A HYBRID FUZZY SYSTEM BASED COOPERATIVE SCALABLE AND SECURED LOCALIZATION SCH...ijwmn
Localization entails position estimation of sensor nodes by employing different techniques and mathematical computations. Localizable sensors also form an inherent part in the functioning of IoT devices and robotics. In this article, the author extends1 a novel scheme for node localization implemented using a hybrid fuzzy logic system to trace the node locations inside the deployment region, presented by the
Abhishek Kumar et. al. The results obtained were then optimized using Gauss Newton Optimization to improve the localization accuracy by 50% to 90% vis-à-vis weighted centroid and other fuzzy based localization algorithms. This article attempts to scale the proposed scheme for large number of sensor nodes to emulate somewhat real world scenario by introducing cooperative localization in previous presented work. The study also analyses the effectiveness of such scaling by comparing the localization accuracy. In next section, the article incorporates security in the proposed cooperative localization approach to detect malicious nodes/anchors by mutual authentication using El Gamel digital Signature scheme. A detailed study of the impact of incorporating security and scaling on average processing time and localization coverage has also been performed. The processing time increased by a factor of 2.5s for 500 nodes (can be attributed to more number of iterations and computations and large deployment area with small radio range of nodes) and coverage remained almost equal, albeit slightly low by a factor of 1% to 2%. Apart from these, the article also discusses the impact of adding extra functionalities in the proposed hybrid fuzzy system based localization scheme on processing time and localization accuracy.Lastly, this study also briefs about how the proposed scalable, cooperative and secure localization scheme tackles the type of attacks that pose threat to localization.

Performance evaluation of data filtering approach in wireless sensor networks...ijmnct
Wireless Sensor Network is a field of research which is viable in every application area like security
services, patient care, traffic regulations, habitat monitoring and so on. The resource limitation of small
sized tiny nodes has always been an issue in wireless sensor networks. Various techniques for improving
network lifetime have been proposed in the past. Now the attention has been shifted towards heterogeneous
networks rather than having homogeneous sensor nodes in a network. The concept of partial mobility has
also been suggested for network longevity. In all the major proposals; clustering and data aggregation in
heterogeneous networks has played an integral role. This paper contributes towards a new concept of
clustering and data filtering in wireless sensor networks. In this paper we have compared voronoi based
ant systems with standard LEACH-C algorithm and MTWSW with TWSW algorithm. Both the techniques
have been applied in heterogeneous wireless sensor networks. This approach is applicable both for critical
as well as for non-critical applications in wireless sensor networks. Both the approaches presented in this
paper outperform LEACH-C and TWSW in terms of energy efficiency and shows promising results for
future work.

In this paper, we explored the possibility of using Genetic Algorithm (GA) being used in Wireless Sensor Networks in general with
specific emphasize on Fault tolerance. In Wireless sensor networks, usually sensor and sink nodes are separated by long communication
distance and hence to optimize the energy, we are using clustering approach. Here we are employing improved K-means clustering algorithm to
form the cluster and GA to find optimal use of sensor nodes and recover from fault as quickly as possible so that target detection won’t be
disrupted. This technique is simulated using Matlab software to check energy consumption and lifetime of the network. Based on the
simulation results, we concluded that this model shows significant improvement in energy consumption rate and network lifetime than other
method such as Traditional clustering or Simulated Annealing

In Ad hoc Network of Nanosensors for Wastage detection, clustering assist in nodal communication and in organization of the data fetched by the nanosensors in the network. The attempt of traditional cluster formation techniques degraded the formation of cluster in a precise manner. The data from the nanosensors which act as the nodes of the network have to be distinctively added into the clusters. The dynamic path selection cluster would achieve this distinct addition by dynamically creating a path to the data as an initial process and then redirecting the data to their appropriate cluster based to the readied scheme.

Abstract Motivation: Gene regulatory network is the network based approach to represent the interactions between genes. DNA microarray is the most widely used technology for extracting the relationships between thousands of genes simultaneously. Gene microarray experiment provides the gene expression data for a particular condition and varying time periods. The expression of a particular gene depends upon the biological conditions and other genes. In this paper, we propose a new method for the analysis of microarray data. The proposed method makes use of S-system, which is a well-accepted model for the gene regulatory network reconstruction. Since the problem has multiple solutions, we have to identify an optimized solution. Evolutionary algorithms have been used to solve such problems. Though there are a number of attempts already been carried out by various researchers, the solutions are still not that satisfactory with respect to the time taken and the degree of accuracy achieved. Therefore, there is a need of huge amount further work in this topic for achieving solutions with improved performances. Results: In this work, we have proposed Clonal selection algorithm for identifying optimal gene regulatory network. The approach is tested on the real life data: SOS Ecoli DNA repairing gene expression data. It is observed that the proposed algorithm converges much faster and provides better results than the existing algorithms. Index Terms: Microarray analysis, Evolutionary Algorithm, Artificial Immune System, S-system, Gene Regulatory Network, SOS Ecoli DNA repairing, Clonal Selection Algorithm.
LIFETIME IMPROVEMENT USING MOBILE AGENT IN WIRELESS SENSOR NETWORKJournal For Research
Wireless sensor networks have attracted much attention in the research community over the last few years, driven by a wealth of theoretical and practical challenges and an increasing number of practical civilian application. ‘one deployment, multiple applications’ is an emerging trend in the development of WSN, due to the high cost of deploying hundreds and thousands of sensors nodes over a wide geographical area and the application-specific nature of tasking a WSN. A wireless sensor network is a collection of nodes organized into a cooperative network. To reduce the energy consumption, the transmission of data between sensor nodes must be reduced in order to preserve the remaining energy in cluster node. We propose a new energy balancing architecture based on cluster with hexagonal geometry with radius R.select the base station and after select the cluster head with maximum energy of the node and after select mobile agent in minimum distance to cluster head and second highest maximum energy. And then send the data mobile agent to cluster head and cluster head to base station.and we have energy management must be followed to balance the energy in the whole network and improving network lifetime.

AN EFFICIENT DEPLOYMENT APPROACH FOR IMPROVED COVERAGE IN WIRELESS SENSOR NET...csandit
Wireless Sensor Networks (WSNs) are experiencing a revival of interest and a continuous advancement in various scientific and industrial fields. WSNs offer favorable low cost and readily deployable solutions to perform the monitoring, target tracking, and recognition of physical events. The foremost step required for these types of ad-hoc networks is to deploy all the sensor nodes in their positions carefully to form an efficient network. Such network should satisfy the quality of service (QoS) requirements in order to achieve high performance levels. In
this paper we address the coverage requirement and its relation with WSN nodes placement problems. In fact, we present a new optimization approach based on the Flower Pollination Algorithm (FPA) to find the best placement topologies in terms of coverage maximization. We have compared the performance of the resulting algorithm, called FPACO, with the original practical swarm optimization (PSO) and the genetic algorithm (GA). In all the test instances, FPACO performs better than all other algorithms.
A new approach for area coverage problem in wireless sensor networks with hyb...ijmnct
One of the most important and basic problems in Wireless Sensor Networks (WSNs) is the coverage
problem. The coverage problem in WSNs causes the security environments is supervised by the existing
sensors in the networks suitably. The importance of coverage in WSNs is so important that is one of the
quality of service parameters. If the sensors do not suitably cover the physical environments they will not
be enough efficient n supervision and controlling. The coverage in WSNs must be in a way that the energy
of the sensors would be the least to increase the lifetime of the network. The other reasons which had
increase the importance of the problem are the topologic changes of the network which are done by the
damage or deletion of some of the sensors and in some cases the network must not lose its coverage. SO, in
this paper we have hybrid the Particle Swarm Optimization (PSO) and Differential Evolution (DE)
algorithms which are the Meta-Heuristic algorithms and have analyzed the area coverage problem in
WSNs. Also a PSO algorithm is implemented to compare the efficiency of the hybrid model in the same
situation. The results of the experiments show that the hybrid algorithm has made more increase in the
lifetime of the network and more optimized use of the energy of the sensors by optimizing the coverage of
the sensors in comparison to PSO.
Comparative study between metaheuristic algorithms for internet of things wir...IJECEIAES
Wireless networks are currently used in a wide range of healthcare, military, or environmental applications. Wireless networks contain many nodes and sensors that have many limitations, including limited power, limited processing, and narrow range. Therefore, determining the coordinates of the location of a node of the unknown location at a low cost and a limited treatment is one of the most important challenges facing this field. There are many meta-heuristic algorithms that help in identifying unknown nodes for some known nodes. In this manuscript, hybrid metaheuristic optimization algorithms such as grey wolf optimization and salp swarm algorithm are used to solve localization problem of internet of things (IoT) sensors. Several experiments are conducted on every meta-heuristic optimization algorithm to compare them with the proposed method. The proposed algorithm achieved high accuracy with low error rate (0.001) and low power consumption.

Solution for intra/inter-cluster event-reporting problem in cluster-based pro...IJECEIAES
In recent years, wireless sensor networks (WSNs) have been considered one of the important topics for researchers due to their wide applications in our life. Several researches have been conducted to improve WSNs performance and solve their issues. One of these issues is the energy limitation in WSNs since the source of energy in most WSNs is the battery. Accordingly, various protocols and techniques have been proposed with the intention of reducing power consumption of WSNs and lengthen their lifetime. Cluster-oriented routing protocols are one of the most effective categories of these protocols. In this article, we consider a major issue affecting the performance of this category of protocols, which we call the intra/inter-cluster event-reporting problem (IICERP). We demonstrate that IICERP severely reduces the performance of a cluster-oriented routing protocol, so we suggest an effective Solution for IICERP (SIICERP). To assess SIICERP’s performance, comprehensive simulations were performed to demonstrate the performance of several cluster-oriented protocols without and with SIICERP. Simulation results revealed that SIICERP substantially increases the performance of cluster-oriented routing protocols.

Over the past few years, there has been a considerable spread of microarray technology in many biological patterns, particularly in those pertaining to cancer diseases like leukemia, prostate, colon cancer, etc. The primary bottleneck that one experiences in the proper understanding of such datasets lies in their dimensionality, and thus for an efficient and effective means of studying the same, a reduction in their dimension to a large extent is deemed necessary. This study is a bid to suggesting different algorithms and approaches for the reduction of dimensionality of such microarray datasets.This study exploits the matrix-like structure of such microarray data and uses a popular technique called Non-Negative Matrix Factorization (NMF) to reduce the dimensionality, primarily in the field of biological data. Classification accuracies are then compared for these algorithms.This technique gives an accuracy of 98%.

Feature Selection Approach based on Firefly Algorithm and Chi-square IJECEIAES
Dimensionality problem is a well-known challenging issue for most classifiers in which datasets have unbalanced number of samples and features. Features may contain unreliable data which may lead the classification process to produce undesirable results. Feature selection approach is considered a solution for this kind of problems. In this paperan enhanced firefly algorithm is proposed to serve as a feature selection solution for reducing dimensionality and picking the most informative features to be used in classification. The main purpose of the proposedmodel is to improve the classification accuracy through using the selected features produced from the model, thus classification errors will decrease. Modeling firefly in this research appears through simulating firefly position by cell chi-square value which is changed after every move, and simulating firefly intensity by calculating a set of different fitness functionsas a weight for each feature. Knearest neighbor and Discriminant analysis are used as classifiers to test the proposed firefly algorithm in selecting features. Experimental results showed that the proposed enhanced algorithmbased on firefly algorithm with chisquare and different fitness functions can provide better results than others. Results showed that reduction of dataset is useful for gaining higher accuracy in classification.

The aim of this investigatation is to compare the utility of machine learning algorithms in distinguishing between untreated and processed mint beside in predicting the spray day of the insecticide. Within seven days, mint treated samples with the malathion insecticide are collected, and their aromas are Studied using a laboratory-manufactured sensor array system based on commercial metallic semiconductor (MOS) gas sensors. To distinguish the mint type, some results of machine learning algorithms were compared to know the decision trees (DT), Naive Bayes, support vector machines (SVM), and ensemble classifier. Furthermore, to predict the treatment day support vector machines regression (SVMR) and partial least squares regression (PLSR) were compared. Regarding the best results, in the discrimination case, a success rate of 92.9% was achieved by the ensemble classifier while in the prediction case, a correlation coefficient of R=0.82 was reached by the SVMR. Good results are achieved if the right gas sensor array system is designed and realized coupled with a good choice of the appropriate machine learning algorithms.
A Classification of Cancer Diagnostics based on Microarray Gene Expression Pr...IJTET Journal
inAbstract— Pattern Recognition (PR) plays an important role in field of Bioinformatics. PR is concerned with processing raw measurement data by a computer to arrive at a prediction that can be used to formulate a decision to be taken. The important problem in which pattern recognition are applied have common that they are too complex to model explicitly. Diverse methods of this PR are used to analyze, segment and manage the high dimensional microarray gene data for classification. PR is concerned with the development of systems that learn to solve a given problem using a set of instances, each instances represented by a number of features. The microarray expression technologies are possible to monitor the expression levels of thousands of genes simultaneously. The microarrays generated large amount of data has stimulate the development of various computational methods to different biological processes by gene expression profiling. Microarray Gene Expression Profiling (MGEP) is important in Bioinformatics, it yield various high dimensional data used in various clinical applications like cancer diagnostics and drug designing. In this work a new schema has developed for classification of unknown malignant tumors into known class. According to this work an new classification scheme includes the transformation of very high dimensional microarray data into mahalanobis space before classification. The eligibility of the proposed classification scheme has proved to 10 commonly available cancer gene datasets, this contains both the binary and multiclass data sets. To improve the performance of the classification gene selection method is applied to the datasets as a preprocessing and data extraction step.
siRNA has become an indispensible tool for silencing gene expression. It can act as an antiviral agent in RNAi pathway against plant diseases caused by plant viruses. However, identification of appropriate features for effective siRNA design has become a pressing issue for researchers which need to be resolved. Feature selection is a vital pre-processing technique involved in bioinformatics data set to find the most discriminative information not only for dimensionality reduction and detection of relevance features but also for minimizing the cost associated with features to design an accurate learning system. In this paper, we propose an ANN based feature selection approach using hybrid GA-PSO for selecting feature subset by discarding the irrelevant features and evaluating the cost of the model training. The results showed that the performance of proposed hybrid GA-PSO model outperformed the results of general PSO.a

Analytical Study of Hexapod miRNAs using Phylogenetic Methodscscpconf
MicroRNAs (miRNAs) are a class of non-coding RNAs that regulate gene expression.
Identification of total number of miRNAs even in completely sequenced organisms is still an
open problem. However, researchers have been using techniques that can predict limited
number of miRNA in an organism. In this paper, we have used homology based approach for
comparative analysis of miRNA of hexapoda group .We have used Apis mellifera, Bombyx
mori, Anopholes gambiae and Drosophila melanogaster miRNA datasets from miRBase
repository. We have done pair wise as well as multiple alignments for the available miRNAs in
the repository to identify and analyse conserved regions among related species. Unfortunately,
to the best of our knowledge, miRNA related literature does not provide in depth analysis of
hexapods. We have made an attempt to derive the commonality among the miRNAs and to
identify the conserved regions which are still not available in miRNA repositories. The results
are good approximation with a small number of mismatches. However, they are encouraging and may facilitate miRNA biogenesis for hexapods.
The analysis of proteins and messenger RNA is commonly used in the comparison of gene expression patterns in tissues or cells of different types and under distinct conditions. In gene expression analysis, normalization is a critical step as it guarantees the validity of downstream analyses. Data preprocessing is an indispensable step in the extraction and normalization of microarray gene expression data. The normalization of gene expression data is essential in ensuring accurate inferences. A number of normalization methods in high throughput sequencing studies are being employed. The preprocessing activity begins by a careful analysis of the gene expression data and usually involves the classification of many raw signal intensities into one expression value. The Robust Multiarray Average (RMA) is a normalization approach for microarrays that involves background correction, normalization and summarization of probe levels information without using MM probes (Lim et al., 2007). It is an algorithm commonly used in the creation of an expression matrix for Affymetrix data and is one of the most commonly used modes of preprocessing to normalize gene expression data. Values of raw intensity are initially background corrected and log2 transformed before being normalized. In order to generate an expression measure for probe sets on each array, a linear model is fitted to the normalized data.

In many diseases classification an accurate gene analysis is needed, for which selection of most informative genes is very important and it require a technique of decision in complex context of ambiguity. The traditional methods include for selecting most significant gene includes some of the statistical analysis namely 2-Sample-T-test (2STT), Entropy, Signal to Noise Ratio (SNR). This paper evaluates gene selection and classification on the basis of accurate gene selection using structured complex decision technique (SCDT) and classifies it using fuzzy cluster based nearest neighborclassifier (FC-NNC). The effectiveness of the proposed SCDT and FC-NNC is evaluated for leave one out cross validation metric(LOOCV) along with sensitivity, specificity, precision and F1-score with four different classifiers namely 1) Radial Basis Function (RBF), 2) Multi-layer perception(MLP), 3) Feed Forward(FF) and 4) Support vector machine(SVM) for three different datasets of DLBCL, Leukemia and Prostate tumor. The proposed SCDT &FC-NNC exhibits superior result for being considered more accurate decision mechanism.
RT-PCR and DNA microarray measurement of mRNA cell proliferationIJAEMSJORNAL
For mRNA quantification, RT-PCR and DNA microarrays have been compared in few studies
(RT-PCR). Healing callus of adult and juvenile rats after femur injury was found to be rich in mRNA at
various stages of the healing process. We used both methods to examine ten samples and a total of 26 genes.
Internal DNA probes tagged with 32P were employed in reverse transcription-polymerase chain reaction
(RT-PCR) to identify genes (RT-PCR). Ten Affymetrix® Rat U34A cRNA microarrays were hybridized with
biotin-labeled cRNA generated from mRNA. There was a wide range of correlation coefficients (r) between
RT-PCR and microarray data for each gene. Meaning became genetically unique because of this diversity.
Relatively lowly expressed genes had the highest r values. The distance between PCR primers and
microarray probes was found to be higher than previously assumed, leading to a drop in agreement between
microarray calls and PCR outcomes. Microarray research showed that RT-PCR expression levels for two
genes had a "floor effect." As a result, PCR primers and microarray probes that overlap in mRNA expression
levels can provide good agreement between these two techniques.

Molecular markers (DNA markers) have entered the scene of genetic improvement in a wide range of horticultural crops. Among the major traits targeted for improvement in horticultural breeding programmes are disease and pest resistance, fruit yield and quality, tree shape, floral morphology, drought tolerance and dormancy. The development of molecular techniques for genetic analysis has led to a great increase in the knowledge of horticultural genetics and understanding and behavior of their genomes. These molecular techniques in particular, molecular markers, have been used to monitor DNA sequence variation in and among the species and create new sources of genetic variation by introducing new and favorable traits from landraces, wild relatives and related species and to fasten the time taken in conventional breeding. Today, markers are also being used for, genetic mapping, gene tagging and gene introgression from exotic and wild species.

Amazon products reviews classification based on machine learning, deep learni...TELKOMNIKA JOURNAL
In recent times, the trend of online shopping through e-commerce stores and websites has grown to a huge extent. Whenever a product is purchased on an e-commerce platform, people leave their reviews about the product. These reviews are very helpful for the store owners and the product’s manufacturers for the betterment of their work process as well as product quality. An automated system is proposed in this work that operates on two datasets D1 and D2 obtained from Amazon. After certain preprocessing steps, N-gram and word embedding-based features are extracted using term frequency-inverse document frequency (TF-IDF), bag of words (BoW) and global vectors (GloVe), and Word2vec, respectively. Four machine learning (ML) models support vector machines (SVM), logistic regression (RF), logistic regression (LR), multinomial Naïve Bayes (MNB), two deep learning (DL) models convolutional neural network (CNN), long-short term memory (LSTM), and standalone bidirectional encoder representations (BERT) are used to classify reviews as either positive or negative. The results obtained by the standard ML, DL models and BERT are evaluated using certain performance evaluation measures. BERT turns out to be the best-performing model in the case of D1 with an accuracy of 90% on features derived by word embedding models while the CNN provides the best accuracy of 97% upon word embedding features in the case of D2. The proposed model shows better overall performance on D2 as compared to D1.

In this study, a microstrip patch antenna that works at 3.6 GHz was built and tested to see how well it works. In this work, Rogers RT/Duroid 5880 has been used as the substrate material, with a dielectric permittivity of 2.2 and a thickness of 0.3451 mm; it serves as the base for the examined antenna. The computer simulation technology (CST) studio suite is utilized to show the recommended antenna design. The goal of this study was to get a more extensive transmission capacity, a lower voltage standing wave ratio (VSWR), and a lower return loss, but the main goal was to get a higher gain, directivity, and efficiency. After simulation, the return loss, gain, directivity, bandwidth, and efficiency of the supplied antenna are found to be -17.626 dB, 9.671 dBi, 9.924 dBi, 0.2 GHz, and 97.45%, respectively. Besides, the recreation uncovered that the transfer speed side-lobe level at phi was much better than those of the earlier works, at -28.8 dB, respectively. Thus, it makes a solid contender for remote innovation and more robust communication.

Improving the detection of intrusion in vehicular ad-hoc networks with modifi...TELKOMNIKA JOURNAL
Vehicular ad-hoc networks (VANETs) are wireless-equipped vehicles that form networks along the road. The security of this network has been a major challenge. The identity-based cryptosystem (IBC) previously used to secure the networks suffers from membership authentication security features. This paper focuses on improving the detection of intruders in VANETs with a modified identity-based cryptosystem (MIBC). The MIBC is developed using a non-singular elliptic curve with Lagrange interpolation. The public key of vehicles and roadside units on the network are derived from number plates and location identification numbers, respectively. Pseudo-identities are used to mask the real identity of users to preserve their privacy. The membership authentication mechanism ensures that only valid and authenticated members of the network are allowed to join the network. The performance of the MIBC is evaluated using intrusion detection ratio (IDR) and computation time (CT) and then validated with the existing IBC. The result obtained shows that the MIBC recorded an IDR of 99.3% against 94.3% obtained for the existing identity-based cryptosystem (EIBC) for 140 unregistered vehicles attempting to intrude on the network. The MIBC shows lower CT values of 1.17 ms against 1.70 ms for EIBC. The MIBC can be used to improve the security of VANETs.
Conceptual model of internet banking adoption with perceived risk and trust f...TELKOMNIKA JOURNAL
Understanding the primary factors of internet banking (IB) acceptance is critical for both banks and users; nevertheless, our knowledge of the role of users’ perceived risk and trust in IB adoption is limited. As a result, we develop a conceptual model by incorporating perceived risk and trust into the technology acceptance model (TAM) theory toward the IB. The proper research emphasized that the most essential component in explaining IB adoption behavior is behavioral intention to use IB adoption. TAM is helpful for figuring out how elements that affect IB adoption are connected to one another. According to previous literature on IB and the use of such technology in Iraq, one has to choose a theoretical foundation that may justify the acceptance of IB from the customer’s perspective. The conceptual model was therefore constructed using the TAM as a foundation. Furthermore, perceived risk and trust were added to the TAM dimensions as external factors. The key objective of this work was to extend the TAM to construct a conceptual model for IB adoption and to get sufficient theoretical support from the existing literature for the essential elements and their relationships in order to unearth new insights about factors responsible for IB adoption.
Efficient combined fuzzy logic and LMS algorithm for smart antennaTELKOMNIKA JOURNAL
The smart antennas are broadly used in wireless communication. The least mean square (LMS) algorithm is a procedure that is concerned in controlling the smart antenna pattern to accommodate specified requirements such as steering the beam toward the desired signal, in addition to placing the deep nulls in the direction of unwanted signals. The conventional LMS (C-LMS) has some drawbacks like slow convergence speed besides high steady state fluctuation error. To overcome these shortcomings, the present paper adopts an adaptive fuzzy control step size least mean square (FC-LMS) algorithm to adjust its step size. Computer simulation outcomes illustrate that the given model has fast convergence rate as well as low mean square error steady state.

Experiments in Tram Chim Park, Vietnam, have been conducted to verify and evaluate the operation of the system.
Wavelet-based sensing technique in cognitive radio networkTELKOMNIKA JOURNAL
Cognitive radio is a smart radio that can change its transmitter parameter based on interaction with the environment in which it operates. The demand for frequency spectrum is growing due to a big data issue as many Internet of Things (IoT) devices are in the network. Based on previous research, most frequency spectrum was used, but some spectrums were not used, called spectrum hole. Energy detection is one of the spectrum sensing methods that has been frequently used since it is easy to use and does not require license users to have any prior signal understanding. But this technique is incapable of detecting at low signal-to-noise ratio (SNR) levels. Therefore, the wavelet-based sensing is proposed to overcome this issue and detect spectrum holes. The main objective of this work is to evaluate the performance of wavelet-based sensing and compare it with the energy detection technique. The findings show that the percentage of detection in wavelet-based sensing is 83% higher than energy detection performance. This result indicates that the wavelet-based sensing has higher precision in detection and the interference towards primary user can be decreased.
A novel compact dual-band bandstop filter with enhanced rejection bandsTELKOMNIKA JOURNAL
In this paper, we present the design of a new wide dual-band bandstop filter (DBBSF) using nonuniform transmission lines. The method used to design this filter is to replace conventional uniform transmission lines with nonuniform lines governed by a truncated Fourier series. Based on how impedances are profiled in the proposed DBBSF structure, the fractional bandwidths of the two 10 dB-down rejection bands are widened to 39.72% and 52.63%, respectively, and the physical size has been reduced compared to that of the filter with the uniform transmission lines. The results of the electromagnetic (EM) simulation support the obtained analytical response and show an improved frequency behavior.
Deep learning approach to DDoS attack with imbalanced data at the application...TELKOMNIKA JOURNAL
A distributed denial of service (DDoS) attack is where one or more computers attack or target a server computer, by flooding internet traffic to the server. As a result, the server cannot be accessed by legitimate users. A result of this attack causes enormous losses for a company because it can reduce the level of user trust, and reduce the company’s reputation to lose customers due to downtime. One of the services at the application layer that can be accessed by users is a web-based lightweight directory access protocol (LDAP) service that can provide safe and easy services to access directory applications. We used a deep learning approach to detect DDoS attacks on the CICDDoS 2019 dataset on a complex computer network at the application layer to get fast and accurate results for dealing with unbalanced data. Based on the results obtained, it is observed that DDoS attack detection using a deep learning approach on imbalanced data performs better when implemented using synthetic minority oversampling technique (SMOTE) method for binary classes. On the other hand, the proposed deep learning approach performs better for detecting DDoS attacks in multiclass when implemented using the adaptive synthetic (ADASYN) method.
The appearance of uncertainties and disturbances often effects the characteristics of either linear or nonlinear systems. Plus, the stabilization process may be deteriorated thus incurring a catastrophic effect to the system performance. As such, this manuscript addresses the concept of matching condition for the systems that are suffering from miss-match uncertainties and exogeneous disturbances. The perturbation towards the system at hand is assumed to be known and unbounded. To reach this outcome, uncertainties and their classifications are reviewed thoroughly. The structural matching condition is proposed and tabulated in the proposition 1. Two types of mathematical expressions are presented to distinguish the system with matched uncertainty and the system with miss-matched uncertainty. Lastly, two-dimensional numerical expressions are provided to practice the proposed proposition. The outcome shows that matching condition has the ability to change the system to a design-friendly model for asymptotic stabilization.

Many systems, including digital signal processors, finite impulse response (FIR) filters, application-specific integrated circuits, and microprocessors, use multipliers. The demand for low power multipliers is gradually rising day by day in the current technological trend. In this study, we describe a 4×4 Wallace multiplier based on a carry select adder (CSA) that uses less power and has a better power delay product than existing multipliers. HSPICE tool at 16 nm technology is used to simulate the results. In comparison to the traditional CSA-based multiplier, which has a power consumption of 1.7 µW and power delay product (PDP) of 57.3 fJ, the results demonstrate that the Wallace multiplier design employing CSA with first zero finding logic (FZF) logic has the lowest power consumption of 1.4 µW and PDP of 27.5 fJ.
Evaluation of the weighted-overlap add model with massive MIMO in a 5G systemTELKOMNIKA JOURNAL
The flaw in 5G orthogonal frequency division multiplexing (OFDM) becomes apparent in high-speed situations. Because the doppler effect causes frequency shifts, the orthogonality of OFDM subcarriers is broken, lowering both their bit error rate (BER) and throughput output. As part of this research, we use a novel design that combines massive multiple input multiple output (MIMO) and weighted overlap and add (WOLA) to improve the performance of 5G systems. To determine which design is superior, throughput and BER are calculated for both the proposed design and OFDM. The results of the improved system show a massive improvement in performance ver the conventional system and significant improvements with massive MIMO, including the best throughput and BER. When compared to conventional systems, the improved system has a throughput that is around 22% higher and the best performance in terms of BER, but it still has around 25% less error than OFDM.

In place of the commercial Pt electrode used in quantum sensitized solar cells, the low-cost CuS cathode is created using electrophoresis. High resolution scanning electron microscopy and X-ray diffraction were used to analyze the structure and morphology of structural cubic samples with diameters ranging from 40 nm to 200 nm. The conversion efficiency of solar cells is significantly impacted by the calcination temperatures of cathodes at 100 °C, 120 °C, 150 °C, and 180 °C under vacuum. The fluorine doped tin oxide (FTO)/CuS cathode electrode reached a maximum efficiency of 3.89% when it was calcined at 120 °C. Compared to other temperature combinations, CuS nanoparticles crystallize at 120 °C, which lowers resistance while increasing electron lifetime.

This article discusses the progressive learning for structural tolerance online sequential extreme learning machine (PSTOS-ELM). PSTOS-ELM can save robust accuracy while updating the new data and the new class data on the online training situation. The robustness accuracy arises from using the householder block exact QR decomposition recursive least squares (HBQRD-RLS) of the PSTOS-ELM. This method is suitable for applications that have data streaming and often have new class data. Our experiment compares the PSTOS-ELM accuracy and accuracy robustness while data is updating with the batch-extreme learning machine (ELM) and structural tolerance online sequential extreme learning machine (STOS-ELM) that both must retrain the data in a new class data case. The experimental results show that PSTOS-ELM has accuracy and robustness comparable to ELM and STOS-ELM while also can update new class data immediately.
Electroencephalography-based brain-computer interface using neural networksTELKOMNIKA JOURNAL
This study aimed to develop a brain-computer interface that can control an electric wheelchair using electroencephalography (EEG) signals. First, we used the Mind Wave Mobile 2 device to capture raw EEG signals from the surface of the scalp. The signals were transformed into the frequency domain using fast Fourier transform (FFT) and filtered to monitor changes in attention and relaxation. Next, we performed time and frequency domain analyses to identify features for five eye gestures: opened, closed, blink per second, double blink, and lookup. The base state was the opened-eyes gesture, and we compared the features of the remaining four action gestures to the base state to identify potential gestures. We then built a multilayer neural network to classify these features into five signals that control the wheelchair’s movement. Finally, we designed an experimental wheelchair system to test the effectiveness of the proposed approach. The results demonstrate that the EEG classification was highly accurate and computationally efficient. Moreover, the average performance of the brain-controlled wheelchair system was over 75% across different individuals, which suggests the feasibility of this approach.
Adaptive segmentation algorithm based on level set model in medical imagingTELKOMNIKA JOURNAL
For image segmentation, level set models are frequently employed. It offer best solution to overcome the main limitations of deformable parametric models. However, the challenge when applying those models in medical images stills deal with removing blurs in image edges which directly affects the edge indicator function, leads to not adaptively segmenting images and causes a wrong analysis of pathologies wich prevents to conclude a correct diagnosis. To overcome such issues, an effective process is suggested by simultaneously modelling and solving systems’ two-dimensional partial differential equations (PDE). The first PDE equation allows restoration using Euler’s equation similar to an anisotropic smoothing based on a regularized Perona and Malik filter that eliminates noise while preserving edge information in accordance with detected contours in the second equation that segments the image based on the first equation solutions. This approach allows developing a new algorithm which overcome the studied model drawbacks. Results of the proposed method give clear segments that can be applied to any application. Experiments on many medical images in particular blurry images with high information losses, demonstrate that the developed approach produces superior segmentation results in terms of quantity and quality compared to other models already presented in previeous works.

Drug addiction is a complex neurobiological disorder that necessitates comprehensive treatment of both the body and mind. It is categorized as a brain disorder due to its impact on the brain. Various methods such as electroencephalography (EEG), functional magnetic resonance imaging (FMRI), and magnetoencephalography (MEG) can capture brain activities and structures. EEG signals provide valuable insights into neurological disorders, including drug addiction. Accurate classification of drug addiction from EEG signals relies on appropriate features and channel selection. Choosing the right EEG channels is essential to reduce computational costs and mitigate the risk of overfitting associated with using all available channels. To address the challenge of optimal channel selection in addiction detection from EEG signals, this work employs the shuffled frog leaping algorithm (SFLA). SFLA facilitates the selection of appropriate channels, leading to improved accuracy. Wavelet features extracted from the selected input channel signals are then analyzed using various machine learning classifiers to detect addiction. Experimental results indicate that after selecting features from the appropriate channels, classification accuracy significantly increased across all classifiers. Particularly, the multi-layer perceptron (MLP) classifier combined with SFLA demonstrated a remarkable accuracy improvement of 15.78% while reducing time complexity.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!

related and RNA such as infections (malaria), cancer, inherited, genetics, physiology, among others [1].
Blood-sucking mosquitoes such as Mosquito Anopheles with vectors of malaria plasmodium falciparum are
found in Africa. Mosquito Anopheles is a deadly malaria parasite, responsible for demises of thousands of
humans daily. Antimalaria combat suppositories blowouts, state-of-the-art antimalarials treatment upsurges,
fetching for ground-breaking medications requires improved biotic studies of this infenctions. The parasite
tolerates precise parameter of gene expression query enormously and necessitates making enhanced thorough
extrapolative model transcriptions of vectors [2].
Approachable revealing genetic inquiries have been made in ribonucleic acid sequencing (RNA-seq)
study by unfolding a cautious purposeful biological strategy for enhancement of the learning. RNA-Seq data
requires removal of expletive high-dimension, such as; noises, complaints, repetition, irrelevant, inactivity,
unfitting data, and others [3]. New capabilities strengthen solutions to the development of ground-breaking
healthcare frameworks such as effective public wellbeing nursing systems, advanced interventions and medical
diagnosis and disorders [4].
Machine learning means have been established with convincing uniqueness to investigate the
enormous amount of cutting-edge RNA-Seq knowledge by studying the naturally material structures [5].

data with kth nearest neighbor (KNN) and decision tree classifiers are proposed to classify discrete genetic
structures and obtain advances that are suitable system for predicting and detecting innovative genes for malaria
ailments in human.
2. REVIEWS
Computational procedures are based on enormous samples of individuals genes with or without
diseases, mutations may be found accountable for the precense of diseases. Differential expressed genes (DEG)
are defined through some methods. Machine Learning measures are important for spotting the variation
between genes found from human genome. Machine learning techniques have been emulated severally in
investigating and classifying various profiles of diseases gene expressions. Various machine learning
approaches are reported and reviewed, using recent trends in the evaluations [4].
Machine learning for predicting Autism spectrum ailment was experimented and classify transcripts,
using RNA data from gene omnibus expression data. This study ranked cluster analysis and relatively
discriminated, using SVM and KNN classifiers, an estimate accuracy of 94% was achieved [9]. Clustering and
classification of RNA-Seq data was carried out by performing a mutual valuation, and emphasizing the
expertise and ploys of methods occurring in recent time as predominant shifts, uing nonlinear and linear
dimension reduction systems, by combining scRNA-seq data [10]. Group of RNA-Seq genes for ranking genes
set of huge ensembles using a supervised learning approach was carried out using random forests classification
method, on 1210 samples of tumor RNA-Seq datasets showed hidden supervised learning selection approaches
necessity on analysis [11]. A supervised single-cell RNA-Seq data classification model was proposed using a
comprehensive approach by combining independent feature selection approaches. scPred RNA-seq datasets
showed high accuracy [12]. RNA-DNA machine learning analysis was proposed to indicate small genome
expression to influence PAH ailment, feature selection algorithm was proposed to classify relevant genes with
an outcome that reveals unique PAH [13].

mosquitos and revealed hidden distinct transcriptional signatures [15].
An ensemble classification algorithm for cancer dataset was developed using decision tree, ensemble
decision trees algorithms on available cancerous microarray, the results enhances than the decision trees
classification [16]. An investigative cancer gene expression ensemble classification method was
proposed using a hybrid RFE-Adaboost algorithm to fetch significant features for enhancing classification
performancet [17]. Classification of cancer data was carried out using an effective ensemble classification
method by increasing the classification, the result were less contingent [18]. A metaheuristics system for
fetching relevant RNA/DNA data genes for classification was proposed by briefing recent developments of
metaheuristic-based methods in embedded feature selection methods, useful data for operatives for ranking
coefficients of SVM classifier is used [19]. A GA presenting a state-of-the-art approach was proposed using
filter-wrapper based feature selection on five biological datasets, the results showed an important reduction of
features for classification [20]. An enhanced ensemble classification for certain features was proposed for
learning an ensemble-based feature selection approach with random trees using a subset, the method removes
the unfitting structures and picks the best structures by means of a probability weighing value for classification
evaluation using RF, SVM, and NB [21]. Review of several feature extraction algorithms for gene expression
investigation, such as the PCA, ICA, PLS, and LLE was carried out and discussed for the purpose of the
machine learning applications [22].

3.1. GA
GA is a wrapper-based feature selection approach that examines suitable features from a given high
dimensional datasets, with numerous parameter procedures, where mutation and crossover operators are
associated with relevant recognized binary constraints features [19]. RNA features with N number denotes a
feature having selected and unselected values 1 and 0 respectively. GA is important and helps to find feature
subset models with selected figure features for composite classifications. GA structure is adopted and
well-defined in Algorithm 1 [20]:
Algorithm 1. Genetic Algorithm
Necessitate: Set parameters nPop = m, tmax, t = 0;
Confirm: Optimal feature subset with the maximum suitable value.
1: while (t<=tmax) do
2: Create pop m, tmax;
3: For k = 1 to m do
4: Parents [m1, m2] = system selection (m, nPop)
5: Child = Xor [m1, m2]
6: M u = mutation [Child}
7: End for
8: Replace m with Child1, Child2, …, Childm
9: t = t+ 1;
10: End while
11: Store the Highest fitness value;
m = population size, r = random number 0 to 1, chrome = certain or non-certain feature through threshold δ,
set value = 0.5, and α = threshold number of picked features. Selecting maximum fit features from the
predictable datasets is the main problem of the GA technique.
3.2. KNN
A supervised learning K-nearest neighbor classification technique for gene datasets, performs
neighborhood classification evaluation value of innovative application occurrence. KNN algorithm classifies
innovative entity developed on instances, attributes as well as training models. KNN classifiers do not train
models to fit but built on retention. The features selected are assumed as input to segments. The K value of
nearest neighbors are selected nearest to the query spot. Detachment between query-instance and training
models are considered and sorted based on the Kth
minimum determined distance. Group Y of the nearest
neighbors is fetched. The unassuming common of the group of nearest neighbors as the estimate amount of the
query instance is used. Bonds can fragment randomly [25].
3.3. Decision trees
Decision tree classification algorithm divides recursively instance spacing with hyperplanes
orthogonally. Decision tree model assembles derivative nodes signifying attributes, based on instance space
attribute value roles selected inversely for algorithms, using its values. Advanced data sub-space iteratively
divides till end principle is determined and terminal nodes (leaf nodes) are allocated to class labels
characterizing the classification. Accurate conventional end procedure is a significant tree with too huge,
overfitted and trivial trees, underfitted and suffers loss in accuracy. Algorithms have assembled overfitting
strategies, labelled trimming, classifying new instances by leading the tree basis down a leaf, with respect to
the examination result along the pathway [26]. Competent models are discovered using decision tree classifiers
and ensembles, with unbalanced varying trained datasets, with resultant models totally unalike.
3.4. Performance evaluation and applications
Machine learning model need evaluation and validation of performance metrics using a confusion
matrix and its formula [4, 27]. Expression of gene analysis suggest enhanced RNA-Seq data path identification,
to learn applicable helpful genes in advancing applications such as treatment modifications, diseases diagnosis,
drugs and gene discoveries, classification of cancers, typhoid, malaria, among other ailments. Designs and
inconsistency findings between machine learning data has discovered great algorithms applicable to many
fields such as engineering, banking, health sectors among others. MATLAB 2015A is proposed as an
experimental and executing tool for the prognosis of malaria infections on an iCore2 processor, 4GB RAM
size, 64-bit System.

resistants and susceptibles of genes is used on a GA to draw optimal reduced number of subsets in the data,
taking away uncorrelated attributes to pick maximum variance features. The result shows important gene
evidence suitable for KNN and decision tree classification algorithm study on MATLAB environment for the
model experiment. Genetic algorithm makes use of 0.5 threshold and achieves 708 optimal subset features of
significant genes. Classifiers used 10-folds cross validation was used on KNN and decision tree classifiers, to
implement evaluations of the model’s performance with 0.05 holdout training data parameter and classifier

Figure 1. Related components were fetched by GA from the full data shown in Figure 1, the subset data features
pass into KNN as well as decision tree and shows the Confusion matix result in the Figure 2 and Figure 3 to
derive the solution to the performance metrics. KNN classification algorithm achieves an accuracy of 88.3%,
while the decision tree classification algorithm achieved an accuracy of 98.3%, metrics of other performance
are shown in Table 1.
