An approach for cross-modality guided quality enhancement of liver imageIJECEIAES
This paper proposes a novel approach for enhancing the contrast of CT liver images using MRI liver images as a guide. The approach has three steps: 1) transforming the CT and MRI images to the same range, 2) adjusting the CT histogram to match the MRI histogram, and 3) applying adaptive histogram equalization to the CT image using two sigmoid functions. Experimental results show that the proposed approach improves image quality metrics like contrast and brightness preservation compared to traditional techniques. Both subjective and objective assessments indicate the approach enhances image contrast while preserving mean brightness and details.

Wide application of proportional-integral-differential (PID)-regulator in industry requires constant improvement of methods of its parameters adjustment. The paper deals with the issues of optimization of PID-regulator parameters with the use of neural network technology methods. A methodology for choosing the architecture (structure) of neural network optimizer is proposed, which consists in determining the number of layers, the number of neurons in each layer, as well as the form and type of activation function. Algorithms of neural network training based on the application of the method of minimizing the mismatch between the regulated value and the target value are developed. The method of back propagation of gradients is proposed to select the optimal training rate of neurons of the neural network. The neural network optimizer, which is a superstructure of the linear PID controller, allows increasing the regulation accuracy from 0.23 to 0.09, thus reducing the power consumption from 65% to 53%. The results of the conducted experiments allow us to conclude that the created neural superstructure may well become a prototype of an automatic voltage regulator (AVR)-type industrial controller for tuning the parameters of the PID controller.

Voltage and frequency control of microgrid in presence of micro-turbine inter...IJECEIAES
The active and reactive load changes have a significant impact on voltage
and frequency. In this paper, in order to stabilize the microgrid (MG) against
load variations in islanding mode, the active and reactive power of all
distributed generators (DGs), including energy storage (battery), diesel
generator, and micro-turbine, are controlled. The micro-turbine generator is
connected to MG through a three-phase to three-phase matrix converter, and
the droop control method is applied for controlling the voltage and
frequency of MG. In addition, a method is introduced for voltage and
frequency control of micro-turbines in the transition state from gridconnected mode to islanding mode. A novel switching strategy of the matrix
converter is used for converting the high-frequency output voltage of the
micro-turbine to the grid-side frequency of the utility system. Moreover,
using the switching strategy, the low-order harmonics in the output current
and voltage are not produced, and consequently, the size of the output filter
would be reduced. In fact, the suggested control strategy is load-independent
and has no frequency conversion restrictions. The proposed approach for
voltage and frequency regulation demonstrates exceptional performance and
favorable response across various load alteration scenarios. The suggested
strategy is examined in several scenarios in the MG test systems, and the
simulation results are addressed.

One of the problems that are associated to power systems is islanding
condition, which must be rapidly and properly detected to prevent any
negative consequences on the system's protection, stability, and security.
This paper offers a thorough overview of several islanding detection
strategies, which are divided into two categories: classic approaches,
including local and remote approaches, and modern techniques, including
techniques based on signal processing and computational intelligence.
Additionally, each approach is compared and assessed based on several
factors, including implementation costs, non-detected zones, declining
power quality, and response times using the analytical hierarchy process

weight of passive methods (24.7%), active methods (7.8%), hybrid methods
(5.6%), remote methods (14.5%), signal processing-based methods (26.6%),
and computational intelligent-based methods (20.8%) based on the
comparison of all criteria together. Thus, it can be seen from the total weight
that hybrid approaches are the least suitable to be chosen, while signal
processing-based methods are the most appropriate islanding detection
method to be selected and implemented in power system with respect to the
aforementioned factors. Using Expert Choice software, the proposed

Robot manipulators have become important equipment in production lines, medical fields, and transportation. Improving the quality of trajectory tracking for
robot hands is always an attractive topic in the research community. This is a
challenging problem because robot manipulators are complex nonlinear systems
and are often subject to fluctuations in loads and external disturbances. This
article proposes an adaptive synchronous sliding control scheme to improve trajectory tracking performance for a robot manipulator. The proposed controller
ensures that the positions of the joints track the desired trajectory, synchronize
the errors, and significantly reduces chattering. First, the synchronous tracking
errors and synchronous sliding surfaces are presented. Second, the synchronous
tracking error dynamics are determined. Third, a robust adaptive control law is
designed,the unknown components of the model are estimated online by the neural network, and the parameters of the switching elements are selected by fuzzy
logic. The built algorithm ensures that the tracking and approximation errors
are ultimately uniformly bounded (UUB). Finally, the effectiveness of the constructed algorithm is demonstrated through simulation and experimental results.
Simulation and experimental results show that the proposed controller is effective with small synchronous tracking errors, and the chattering phenomenon is
significantly reduced.

The module minimizes hardware resource utilization while enabling the acquisition of a large number of data samples from the signal during the experiments by adaptively compressing the signal prior to data transmission. The results demonstrate an average compression ratio of 2.90 across three benchmark signals, indicating efficient signal acquisition and effective debugging and analysis. This method allows users to acquire more data samples than conventional methods. The proposed lab allows students to remotely test and debug their designs, bridging the gap between theory and practice in embedded system design.

Over the past few years, the internet of things (IoT) has advanced to connect billions of smart devices to improve quality of life. However, anomalies or malicious intrusions pose several security loopholes, leading to performance degradation and threat to data security in IoT operations. Thereby, IoT security systems must keep an eye on and restrict unwanted events from occurring in the IoT network. Recently, various technical solutions based on machine learning (ML) models have been derived towards identifying and restricting unwanted events in IoT. However, most ML-based approaches are prone to miss-classification due to inappropriate feature selection. Additionally, most ML approaches applied to intrusion detection and prevention consider supervised learning, which requires a large amount of labeled data to be trained. Consequently, such complex datasets are impossible to source in a large network like IoT. To address this problem, this proposed study introduces an efficient learning mechanism to strengthen the IoT security aspects. The proposed algorithm incorporates supervised and unsupervised approaches to improve the learning models for intrusion detection and mitigation. Compared with the related works, the experimental outcome shows that the model performs well in a benchmark dataset. It accomplishes an improved detection accuracy of approximately 99.21%.
Applications of artificial Intelligence in Mechanical Engineering.pdfAtif Razi
Historically, mechanical engineering has relied heavily on human expertise and empirical methods to solve complex problems. With the introduction of computer-aided design (CAD) and finite element analysis (FEA), the field took its first steps towards digitization. These tools allowed engineers to simulate and analyze mechanical systems with greater accuracy and efficiency. However, the sheer volume of data generated by modern engineering systems and the increasing complexity of these systems have necessitated more advanced analytical tools, paving the way for AI.
AI offers the capability to process vast amounts of data, identify patterns, and make predictions with a level of speed and accuracy unattainable by traditional methods. This has profound implications for mechanical engineering, enabling more efficient design processes, predictive maintenance strategies, and optimized manufacturing operations. AI-driven tools can learn from historical data, adapt to new information, and continuously improve their performance, making them invaluable in tackling the multifaceted challenges of modern mechanical engineering.

Prediction of Electrical Energy Efficiency Using Information on Consumer's Ac...PriyankaKilaniya
Energy efficiency has been important since the latter part of the last century. The main object of this survey is to determine the energy efficiency knowledge among consumers. Two separate districts in Bangladesh are selected to conduct the survey on households and showrooms about the energy and seller also. The survey uses the data to find some regression equations from which it is easy to predict energy efficiency knowledge. The data is analyzed and calculated based on five important criteria. The initial target was to find some factors that help predict a person's energy efficiency knowledge. From the survey, it is found that the energy efficiency awareness among the people of our country is very low. Relationships between household energy use behaviors are estimated using a unique dataset of about 40 households and 20 showrooms in Bangladesh's Chapainawabganj and Bagerhat districts. Knowledge of energy consumption and energy efficiency technology options is found to be associated with household use of energy conservation practices. Household characteristics also influence household energy use behavior. Younger household cohorts are more likely to adopt energy-efficient technologies and energy conservation practices and place primary importance on energy saving for environmental reasons. Education also influences attitudes toward energy conservation in Bangladesh. Low-education households indicate they primarily save electricity for the environment while high-education households indicate they are motivated by environmental concerns.

This paper deals with the classification of the kidneys for renal stones on
ultrasound images. Convolutional neural network (CNN) and pre-trained
CNN (VGG16) models are used to extract features from ultrasound images.
Extreme gradient boosting (XGBoost) classifiers and random forests are used
for classification. The features extracted from CNN and VGG16 are used to
compare the performance of XGBoost and random forest. An image with
normal and renal stones was classified. This work uses 630 real ultrasound
images from Al-Diwaniyah General Teaching Hospital (a lithotripsy center)

1. INTRODUCTION
The kidneys’ primary function is to keep the body in balance (homeostasis) by regulating fluid levels,
regulating salt levels inside the body, and removing waste products from the blood. Mineral and salt deposits
form inside the kidneys, causing renal stones. They can damage any part of the urinary tract, from the kidneys
to the bladder. Minerals crystallize and bond together in concentrated urine, creating stones. This condition
might be due to various factors, including diet, excess body weight, medical conditions, and specific nutritional
supplements and drugs. Kidney stone illness affects people of all races. However, whites are the most affected,
followed by Hispanics, Blacks, and Asians [1]. Kidney stones are considered a systemic issue associated with
metabolic syndrome. The end-stage renal disease affects 2% to 3% of patients with combined nephrolithiasis
and nephrocalcinosis [2]. Chronic kidney disease is more likely to occur in patients with a history of kidney
stones [3]. When these calculi stones migrate through the ureter, they obstruct urine flow and cause intense
discomfort known as renal colic. Urolithiasis can potentially cause morbidity and damage to the kidneys [4].
Ultrasonography, often known as ultrasound imaging, is a technique for visually inspecting interior
tissues, muscles, and organs and performing quantitative analysis. Ultrasound is used to obtain measurements
to diagnose disorders [5]. Ultrasound is performed as the first-line imaging examination of the abdomen and
kidneys. Ultrasound is a safe, non-invasive, non-radioactive imaging modality [6]. Kidney stones seem brighter
and more hyperechoic in ultrasound images because most ultrasound waves are reflected in the transducer [7],
[8]. Recently, deep learning has become one of the most prominent subjects in artificial intelligence [9]. The
architecture of the deep convolutional network leads to hierarchical feature extraction [10]. Convolutional

neural networks (CNNs) are a prominent area of study in image recognition research. CNN successfully
processes raw pixel data for image categorization [11]. Correctly classifying medical images is critical for
improving clinical care and therapy [12]. The deep CNN model is good at extracting features from images and
classifying them. Deep learning algorithms extract essential features from data and have state-of-the-art
accuracy, often surpassing that of individual intelligence [13]. CNN is the most widely used machine learning
algorithm because it automatically discovers essential features without human intervention [14]. Visual
geometry group-16 (VGG16) is a deep CNN (DCNN) [15].
Verma et al. [16] suggested a method for the detection of kidney stones or the absence of stones. Image
enhancement was performed via the average filter, the Gaussian filter, and unsharp masking. Next, morphological
procedures such as erosion and stretching, and entropy-based segmentation were applied to determine the region
of interest. Principal component analysis (PCA) was used for feature extraction and reduction, and then k-nearest
neighbor (k-NN) and support vector machine (SVM) classifiers were applied for classification. An examination
of these two methods revealed that k-NN is superior to SVM. The accuracy of k-NN was 89%, while that of SVM
was 84%. Sudharson and Kokil [17] introduced pre-trained DNN models, which were given three alternative
datasets for extracting features and then classified using SVM. The model classifies the ultrasound images of the
kidney into four categories: normal, cyst, stone, and tumor. When evaluated with high-quality images, the
approach had a classification accuracy of 96.54% and 95.58% when noisy images were employed. Srivastava
et al. [18] presented a common VGG16 model that was fine-tuned using its collection of ultrasound images. The
model can tell if the ultrasound scans indicate an ovarian cyst or not and has an accuracy rate of 92.11%. Kokil
and Sudharson [19] introduced an algorithm for automatically detecting and classifying kidney abnormalities.
Pre-trained CNNs were utilized to extract features fromthe kidney ultrasound images. The extracted features were
input into an SVM classifier to identify kidney abnormalities. The images were divided into three categories:
normal, cystic, and stoned. A performance review was conducted, and 91.8% accuracy was achieved. The
proposed models focus on features extracted by CNN and VGG16. Diagnose abnormalities in renal ultrasound
images by using machine learning algorithms.

2.1. Data collection
Real images from Al-Diwaniyah General Teaching Hospital (Lithotripsy Center), Iraq, were collected
using a Philips HD11 XE ultrasound system with image dimensions of 800×600 and digital imaging and
communications in medicine (DICOM) format. The images were diagnosed by three radiologists and five
urologists and classified into two groups: renal and normal renal stones. A total of 630 images-315 normal
images and 315 stone images—were obtained.
2.2. Pre-processing
In medical imaging, data preparation is essential. In many cases, pre-processing steps are mandatory
for meaningful data analysis [20]. Pre-processing is accomplished in this study using four steps, including
image format, cropping, resizing, and normalization.
2.2.1. Image format
Renal ultrasound images were converted from DICOM to bitmap format. Then, the files were
arranged, and the images were separated randomly into 70% (440 images for training) and 30% (190 for
testing). Some images of normal kidneys and those containing stones are shown in Figures 2(a) and 2(b).

(b)
Figure 2. Renal ultrasound images (a) normal and (b) stone
2.2.2. Region of interest
Region of interest (ROI) is the process of cropping unwanted areas or unneeded information from
ultrasound images, such as the patient’s name and scanning details. It increases the classification process’s
speed and efficiency [21]. In the present work, a rectangular ROI is identified in the middle of images, and the
images are cropped to a size of 512×512.
2.2.3. Resizing
Image size is adjusted without changing the amount of data in the image. Image resizing is used in
image processing to increase and decrease the size of an image in pixel format [22]. In the present work, the
images are scaled to a uniform size of 224×224.
2.2.4. Normalization
Normalization divides original data by 255 to ensure that all variance values are between 0 and 1.
Normalization may be valuable for prediction [23]. It is beneficial for neural network-based classification
methods [24].
2.3. Feature extraction
Feature extraction requires modifying the original features to create more significant features. Deep
learning, especially when utilizing CNN, does not require a sophisticated way to extract features. CNN-trained
datasets produce a wide range of results depending on the architecture and datasets [25]. More features
correspond to increased difficulty in visualizing and interacting with the training dataset. For this research,
CNN and VGG16 features were extracted from the convolution layer.

2.3.1. CNN
The CNN algorithm is a well-known and widely used algorithm that works by sending an image
through a series of layers and then outputting a single class from a set of possible image classes [26]. It is
capable of learning invariant local properties [26]. The advantages of CNN over other types of neural networks
are its weight-sharing features, concurrent learning of the feature extraction layer and classification layers, and
large-scale network implementation. CNN is a supervised learning method with several fully connected layers
– including several hidden layers, an input layer, an output layer, and normalization layers [15] – that function
similarly to individuals. In this study, the CNN consists of four convolution layers (conv2D), two
MaxPooling2D, and four BatchNormalization layers. The fully connected layers (dense layer) are completely
removed, as shown in Figure 3.
Figure 3. Structure of the CNN architecture
2.3.2. VGG16
VGG16-DCNN is assigned weights learned from the ImageNet database [12]. VGG16 has achieved
high performance in feature extraction in medical imaging [9]. VGG-16 comprises 16 layers with configurable
parameters (13 convolutional layers and three fully connected layers). In this research, the model is initially
loaded to extract features with ImageNet-trained weights without fully connected layers (dense layers) of the
classifier and by making loaded layers non-trainable. Afterward, features are extracted from VGG16 ImageNet
weights to the classifier for prediction, as shown in Figure 4.
Figure 4. Structure of the VGG16 architecture
2.4. Classification algorithms
Image classification aims to lower the model’s computational complexity, which is expected to rise if
the input includes images. Image classification is a major part of the significant medical imaging concerns. The
ultimate objective of medical imaging analysis is to classify images from several modalities to discriminate
among different illness types of biomarkers [27]. Two machine learning techniques are used to diagnose
ultrasound images: extreme gradient boosting (XGBoost) and random forest (RF).

2.4.1. XGBoost
XGboost is a decision tree boosting algorithm at its core. An ensemble learning procedure requires
developing numerous models consecutively, with each new model trying to adjust for the deficiencies of the
prior model [28]. The program first offers potential splitting points based on feature distribution percentiles.
Then, the algorithm splits the continuous features into buckets specified by these option points, aggregates the
statistics, and selects the best solution from among the suggestions based on the aggregated data [29]. Each
iteration of the algorithm adds a new decision tree to the existing decision trees to increase the value of the
desired function. The objective function of XGBoost is the sum of the loss function calculated over whole
predictions and a regularization function for each prediction (K trees) [30].
𝑂𝑏𝑗 = ∑ 𝑙(𝒴𝑖, 𝒴
̂)
𝑛
𝑖=1 + ∑ Ω(𝑓𝑘)
𝐾
𝑘=1 (1)
where 𝑙(𝒴𝑖, 𝒴
̂) is training loss measures how well the model fits on training data, Ω is regularization measures
the complexity of trees, and K is number of trees. In this suggested approach, the XGBoost classifier makes
accurate assumptions to obtain the best tree model.
2.4.2. Random forest
Random forest (RF) is a classification approach that uses ensemble learning and is widely used with
large training datasets and many input variables. The decision tree is a popular classifier because of its fast
execution speed [31]. The method’s essence is the construction of several trees in randomly chosen subspaces
of the feature set. Trees in various subspaces extend the classification in distinctive ways. Their overall
classification can be incrementally improved [32]. RF’s primary benefit is that it enhances forecast accuracy
without raising computing expenses [33]. In the present research, the performance of the RF created with 50
trees trained with CNN and VGG16 features is investigated.
3. RESULTS AND DISCUSSION
Every experiment is performed using a Dell laptop with the following specifications: Intel® Core™
i7-6600U central processing unit (CPU) and 64-bit operating system. Python 3.9.7 is used. The installed
software includes Anaconda Navigator, Spyder, and Python. The models are evaluated using a hold-out
(70% to 30%) train–test split and K-fold cross-validation (K=5) for measuring the model’s classification
performance. A confusion matrix of the selected classifiers is utilized to evaluate the performance parameters,
as shown in Figure 5.
The comparison shows that when CNN was used with XGBoost and RF classifiers, the classification
accuracy was 99.47% and 98.94% for CNN-XGBoost and CNN-RF, respectively. These results were better
than those of VGG16 when used with the same classifier. The accuracy of VGG16-RF and VGG16-XGBoost
is 85.26% and 93.68%, respectively.
These models are evaluated using accuracy, precision, recall, and F1-score. Through the use of
(2) to (5), the true negative (TN), true positive (TP), false negative (FN), and false positive (FP) values are
calculated [34]. Accuracy is the ratio of the true predicted observation to the total observation, as determined
by (2).

Figure 5. Confusion matrix of selected classifiers
A receiver operating characteristic (ROC) curve is a graph that shows the performance of a
classification model over all classification thresholds. This curve demonstrates two parameters: TP rate and FP
rate. The area under the (AUC) is measured to determine the ability of a classification system to distinguish
between the classes. Figure 6 shows the charting of the ROC and AUC curves for the four models. For K-fold
cross-validation, the data are divided into k parts. One part is set aside for validation for each iteration, and the
other parts are combined and used to train the model. Finally, the average cross-validation performance across
all iterations is used to evaluate the model. As a final stage in optimizing the model performance, K-fold
validation (K = 5) was performed on the four models, as shown in Table 1. Table 2 shows the performance of
various classifiers.
In this work, four models are proposed to detect abnormalities from renal ultrasound images using
local datasets from Iraqi centers. Good performance (96.54% accuracy) was achieved on three variant datasets
using the pre-trained DNN models and SVM for classification. The model classifies the ultrasound images of
the kidney into four categories: normal, cyst, stone, and tumor [17]. The pre-trained off-the-shelf CNN was
utilized to extract features from the kidney ultrasound images, and the SVM classifier was used to classify
kidney images into normal, cystic, and stoned kidneys. A performance review was conducted, and 91.8%
accuracy was achieved [19].
This paper proposes four models to classify renal stone ultrasound images. The proposed CNN-
XGBoost and CNN-RF models have better classification accuracy than VGG16-XGBoost and VGG16-RF.
The accuracy of CNN-XGBoost and CNN-RF, VGG16-XGBoost, and VGG16-RF is 99.47%, 98.94%, 93.68,
and 85.26%, respectively.

4. CONCLUSION
Renal stone classification models were established using CNN and VGG16 for feature extraction and
XGBoost and RF as classifiers. The proposed models indicated that the performance of feature extraction with
CNN and the use of the classifier with XGBoost and RF is better than that of the pre-trained network VGG16.
The features of XGBoost and RF are based on classification accuracy. The developed kidney stone
classification models will serve as a supportive toolfor radiologists, especially in Iraq. Given the acknowledged
lack of clinical investigations and diagnostic capabilities, these models offer a possible solution to the loaded
clinical situation in Iraq. In addition, these models can classify abnormalities of renal ultrasound images such
as hydronephrosis (stones in the ureters), cysts, kidney failure, and tumors.
