Dynamic thresholding on speech segmentation
This document discusses several dynamic thresholding approaches for segmenting continuous Bangla speech sentences into words or subwords. It proposes using k-means clustering, fuzzy c-means clustering (FCM), and Otsu's thresholding method to determine optimal thresholds for segmentation. K-means and FCM clustering produce better segmentation results than Otsu's method. The algorithms are implemented in MATLAB and achieve an average segmentation accuracy of 94%. Blocking black areas and boundary detection techniques are used to properly detect word boundaries in continuous speech and label the segmented units.
Dynamic thresholding on speech segmentation
Abstract Word is the preferred and natural unit of speech, because word units have well defined acoustic representation. This paper presents several dynamic thresholding approaches for segmenting continuous Bangla speech sentences into words/sub-words. We have proposed three efficient methods for speech segmentation: two of them are usually used in pattern classification (i.e., k-means and FCM clustering) and one of them is used in image segmentation (i.e., Otsu’s thresholding method). We also used new approaches blocking black area and boundary detection techniques to properly detect word boundaries in continuous speech and label the entire speech sentence into a sequence of words/sub-words. K-Means and FCM clustering methods produce better segmentation results than that of Otsu’s Method. All the algorithms and methods used in this research are implemented in MATLAB and the proposed system achieved the average segmentation accuracy of 94% approximately. Keywords: Blocking Black Area, Clustering, Dynamic Thresholding, Fuzzy Logic and Speech Segmentation.

A Parallel Architecture for Multiple-Face Detection Technique Using AdaBoost ...
Face detection is a very important biometric application in the field of image
analysis and computer vision. The basic face detection method is AdaBoost
algorithm with a cascading Haar-like feature classifiers based on the
framework proposed by Viola and Jones. Real-time multiple-face detection,
for instance on CCTVs with high resolution, is a computation-intensive
procedure. If the procedure is performed sequentially, an optimal real-time
performance will not be achieved. In this paper we propose an architectural
design for a parallel and multiple-face detection technique based on Viola
and Jones' framework. To do this systematically, we look at the problem
from 4 points of view, namely: data processing taxonomy, parallel memory
architecture, the model of parallel programming, as well as the design of
parallel program. We also build a prototype of the proposed parallel
technique and conduct a series of experiments to investigate the gained
acceleration.

Patterns for the internet of things (IoT) which represent proven solutions used to solve design problems in the IoT are numerous. Similar to objectoriented design patterns, these IoT patterns contain multiple mutual heterogeneous relationships. However, these pattern relationships are hidden and virtually unidentified in most documents. In this paper, we use machine learning techniques to automatically mine knowledge graphs to map these relationships between several IoT patterns. The end result is a semantic knowledge graph database which outlines patterns as vertices and their relations as edges. We have identified four main relationships between the IoT patterns-a pattern is similar to another pattern if it addresses the same use case problem, a large-scale pattern uses a small- scale pattern in a lower level layer, a large pattern is composed of multiple smaller scale patterns underneath it, and patterns complement and combine with each other to resolve a given use case problem. Our results show some promising prospects towards the use of machine learning techniques to generate an automated repository to organise the IoT patterns, which are usually extracted at various levels of abstraction and granularity.

The system extracts fingerprint features using Dual Tree Complex Wavelet Transforms and extracts face features using Discrete Wavelet Transforms. It then concatenates the fingerprint and face features into a single feature vector. Euclidean distance is used to match test biometrics to those stored in a database. The proposed algorithm is shown to achieve better equal error rates and true positive identification rates compared to individual transformation domain techniques.

This document discusses network reconfiguration in distribution systems with variable load demand. It outlines the benefits of reconfiguration during normal and abnormal operation, including loss reduction and reliability improvement. The objectives are defined as minimizing losses while satisfying radial topology and equipment constraints. Two cases are studied for fixed loads: with and without distributed generation. Variable demand is also analyzed using a fixed configuration and hourly reconfiguration approach. Results on a test system show the fixed approach achieves lower losses with fewer switching operations than the hourly method. In conclusion, reconfiguration reduces losses and improves voltage, while fixed switching is preferred to hourly switching due to lower operational costs and disturbances.

Run time dynamic partial reconfiguration using microblaze soft core processor...
aydeshmukh@gmail.com
Abstract
DSP Application requires a fast computations & flexibility of the design. Partial Reconfiguration (PR) is an advanced technique,
which improves the flexibility of FPGAs by allowing portions of a design to be reconfigured at runtime by overwriting parts of the
configuration memory. In this paper we are using microblaze soft core processor & ICAP Port to reconfigure the FPGA at runtime.
ICAP is accessed through a light-weight custom IP which requires bit stream length, go, and done signal to interface to a system that
provides partial bit stream data. The partial bit stream is provided by the processor system by reading the partial bit files from the
compact flash card. Our targeted DSP application is matrix multiplication; we are reconfiguring design by changing partial modules
at run time. To change the partial bit stream we interfaces a microblaze Soft processor & using a UART interface.ISE13.1 &
PlanAhead is used for partial reconfiguration of FPGA .EDK is used for microblaze soft processor design & ICAP Interface .The
simulation is done using Chip Scope Logic Analyzer & the complete hardware implementation is done on Xilinx VIRTEX -6 ML605
Platform.
Keywords — PlanAhead, EDK, Dynamic partial reconfiguration, ICAP, Matrix multiplication, Chipscope pro analysis,

This document discusses network reconfiguration in distribution systems with variable load demand. It outlines the benefits of reconfiguration during normal and abnormal operation, including loss reduction and reliability improvement. The objectives are defined as minimizing losses while satisfying radial topology and equipment constraints. Two cases are studied for fixed loads: with and without distributed generation. Variable demand is also analyzed using a fixed configuration and hourly reconfiguration approach. Results on a test system show the fixed approach achieves lower losses with fewer switching operations than the hourly method. In conclusion, reconfiguration reduces losses and improves voltage, while fixed switching is preferred to hourly switching due to lower operational costs and disturbances.

Abstract
DSP Application requires a fast computations & flexibility of the design. Partial Reconfiguration (PR) is an advanced technique,
which improves the flexibility of FPGAs by allowing portions of a design to be reconfigured at runtime by overwriting parts of the
configuration memory. In this paper we are using microblaze soft core processor & ICAP Port to reconfigure the FPGA at runtime.
ICAP is accessed through a light-weight custom IP which requires bit stream length, go, and done signal to interface to a system that
provides partial bit stream data. The partial bit stream is provided by the processor system by reading the partial bit files from the
compact flash card. Our targeted DSP application is matrix multiplication; we are reconfiguring design by changing partial modules
at run time. To change the partial bit stream we interfaces a microblaze Soft processor & using a UART interface.ISE13.1 &
PlanAhead is used for partial reconfiguration of FPGA .EDK is used for microblaze soft processor design & ICAP Interface .The
simulation is done using Chip Scope Logic Analyzer & the complete hardware implementation is done on Xilinx VIRTEX -6 ML605
Platform.

Distribution network reconfiguration for loss reduction and voltage
This document presents a technique for distribution network reconfiguration to reduce power losses and improve voltage profiles using Bacterial Particle Swarm Optimization (B-PSO). The technique was tested on three IEEE standard test networks - a 16-bus system, 33-bus system, and 69-bus system. For each test system, the proposed technique optimized the open/closed status of sectionalizing and tie switches to minimize losses and voltage deviations while maintaining radial network topology. Results showed reductions in power losses of 12-56% and improvements in voltage profiles for all three test systems. Future work could incorporate distributed generation to support overloaded feeders from load transfers during reconfiguration.
Introducing Undergraduate Electrical Engineering Students to Chaotic Dynamics...
In current undergraduate electrical engineering, the emphasis on linear systems develops a way of thinking that dismisses nonlinear dynamics as spurious oscillations. The linear systems approach oversimplifies the dynamics of nonlinear systems. This talk helps students understand chaotic behavior using simulations of a continuous-time circuit and a discrete-time system. The undergraduate students and teachers can recognize the educational value of chaotic phenomena from them.

This document summarizes a physics colloquium presentation about strange attractors in chaotic systems. Strange attractors are fractal patterns that arise in some dynamical systems and are characterized by sensitivity to initial conditions and having a non-integer fractal dimension. The presentation outlines examples of strange attractors like the Lorenz and Hénon attractors. It discusses properties of strange attractors like attractor dimension and Lyapunov exponents. It also shows that chaos is more common at higher dimensions and in neural networks, and evaluates the aesthetic appeal of strange attractors.

Encryption & Decryption of Sound in image format on Matlab
Using this software any 50 sec audio message can be decrypted into image file and then original message can again be recovered from image file. This project is coded in Matlab and gui is also built in Matlab.
Chaos Theory
Chaos theory deals with nonlinear and complex systems that are highly sensitive to initial conditions. These systems, while deterministic, are largely unpredictable due to this sensitivity. Lorenz discovered this "butterfly effect" through modeling atmospheric convection. Chaotic systems evolve toward attractors, which can be fixed points, limit cycles, or strange attractors exhibiting fractal geometry. This geometry is seen throughout nature. While chaotic systems cannot be precisely predicted, control methods like Ott-Grebogi-Yorke can influence their behavior. Chaos theory has applications across many domains.
Image Encryption in java ppt.
The document proposes a chaotic image encryption technique using Henon chaotic systems. It consists of two main steps: 1) Image fusion between the original image and a key image. 2) Encrypting the pixel values of the fused image using a Henon chaotic map. The technique aims to provide high security with less computational time compared to traditional encryption methods. Experimental results show the algorithm is sensitive to keys and resistant to brute force attacks. The technique can be used for applications like secure internet image transmission.
Image encryption and decryption
Encryption converts plaintext into ciphertext using an algorithm and key. Gaussian elimination with partial pivoting and row exchange is used to encrypt images by converting the image matrix to an upper triangular matrix and generating a decryption key. The encrypted image matrix and key can then be multiplied to recover the original image matrix and decrypt the image. This algorithm allows for faster encryption time while still producing robust encryption to prevent unauthorized access to images.
Chaos Theory: An Introduction
Chaos theory is a mathematical field of study which states that non-linear dynamical systems
that are seemingly random are actually deterministic from much simpler equations. The
phenomenon of Chaos theory was introduced to the modern world by Edward Lorenz in 1972
with conceptualization of ‘Butterfly Effect’. As chaos theory was developed by inputs of
various mathematicians and scientists, it found applications in a large number of scientific
fields.
The purpose of the project is the interpretation of chaos theory which is not as familiar as
other theories. Everything in the universe is in some way or the other under control of Chaos
or product of Chaos. Every motion, behavior or tendency can be explained by Chaos Theory.
The prime objective of it is the illustration of Chaos Theory and Chaotic behavior.
This project includes origin, history, fields of application, real life application and limitations
of Chaos Theory. It explores understanding complexity and dynamics of Chaos.

This document summarizes a research paper that proposes a novel technique for visual cryptography to securely transmit visual information. The technique encrypts images into shares using chaotic pseudo-random number generation, zigzag scan pattern, and pixel index reversal to increase security. It also aims to reduce image degradation by applying the methods to individual RGB color channels rather than just grayscale. The results demonstrate that the proposed approach increases security without increasing file size like previous methods, and improves image quality by enabling color images.

Lightweight digital imaging and communications in medicine image encryption f...
Diagnosis in healthcare systems relies heavily on the use of medical images. Images such as X-rays, ultrasounds, computed tomography (CT) scans, magnetic resonance imaging (MRIs), and other scans of the brain and other internal organs of patients include private and personal information. However, these images are vulnerable to unauthorized users who unlawfully use them for non-diagnostic reasons due to the lack of security in communication routes and the gaps in the storage systems of hospitals or medical centers. Image encryption is a prominent technique used to protect medical images from unauthorized access in addition to enhancing the security of communication networks. In this paper, researchers offer a lightweight cryptosystem for the secure encryption of medical images that makes use of the present block cipher and a five-dimensional chaotic map. More than 25 images from the open science framework (OSF) public database of patients with coronavirus disease 2019 (COVID-19) were used to evaluate the proposed system. DICOM stands for “digital imaging and communications in medicine”. The efficiency of the proposed system is proved in terms of adjacent pixels’ correlation analysis, National Institute of Standards and Technology (NIST) analysis, mean square error, information entropy, unified average changing intensity, peak-to-signal noise ratio, entropy, and structure similarity index image.

Insecure communication in digital image security and image storing are considered as important challenges. Moreover, the existing approaches face problems related to improper security at the time of image encryption and decryption. In this research work, a wavelet environment is obtained by transforming the cover image utilizing integer wavelet transform (IWT) and hybrid discrete cosine transform (DCT) to completely prevent false errors. Then the proposed hybrid chaotic map with L-shaped fractal Tromino offers better security to maintain image secrecy by means of encryption and decryption. The proposed work uses fractal encryption with the combination of L-shaped Tromino theorem for enhancement of information hiding. The regions of L-shaped fractal Tromino are sensitive to variations, thus are embedded in the watermark based on a visual watermarking technique known as reversible watermarking. The experimental results showed that the proposed method obtained peak signal-to-noise ratio (PSNR) value of 56.82dB which is comparatively higher than the existing methods that are, Beddington, Free, and Lawton (BFL) map with PSNR value of 8.10 dB, permutation substitution, and Boolean operation with PSNR value of 21.19 dB and deoxyribonucleic acid (DNA) level permutation-based logistic map with PSNR value of 21.27 dB.

An ideal steganographic scheme in networks using twisted payload
Abstract With the rapid development of network technology, information security has become a mounting problem. Steganography involves hiding information in a cover media, in such a way that the cover media is not supposed to have any confidential message for its unintentional addressee In this paper, an ideal steganographic scheme in networks is proposed using twisted payload. The confidential image values are twisted by using scrambling techiques.The Discrete Wavelet Transform (DWT) is applied on cover image and Integer Wavelet Transform (IWT) is applied to the scrambled confidential image. Merge operation is done on both images and Inverse DWT is computed on the same to get the stego image. The information hiding algorithm is the reverse process of the extracting algorithm. After this an ideal steganographic scheme is applied which generates a stego image which is immune against conventional attack and performs good perceptibility compared to other steganographic approaches.

CHARACTER RECOGNITION USING NEURAL NETWORK WITHOUT FEATURE EXTRACTION FOR KAN...
Handwriting recognition has been one of the active and challenging research areas in the
field of pattern recognition. It has numerous applications which include, reading aid for blind, bank
cheques and conversion of any hand written document into structural text form[1]. As there are no
sufficient number of works on Indian language character recognition especially Kannada script
among 15 major scripts in India[2].In this paper an attempt is made to recognize handwritten
Kannada characters using Feed Forward neural networks. A handwritten kannada character is resized
into 60x40 pixel.The resized character is used for training the neural network. Once the training
process is completed the same character is given as input to the neural network with different set of
neurons in hidden layer and their recognition accuracy rate for different kannada characters has been
calculated and compared. The results show that the proposed system yields good recognition
accuracy rates comparable to that of other handwritten character recognition systems.

The document summarizes a two-branch parallel RC circuit Simulink model of a lithium polymer battery. The model parameters depend on temperature and state of charge, which are represented using 2D lookup tables. User-defined functions calculate open circuit voltage and internal resistance. A dedicated block autonomously detects charge/discharge transitions and resets the current integrator. Comparisons to experimental data show maximum errors of 3% for dynamic responses and 5% for static discharging responses.

Applications of artificial Intelligence in Mechanical Engineering.pdf
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...
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.
DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODEL
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.

Height and depth gauge linear metrology.pdf
Height gauges may also be used to measure the height of an object by using the underside of the scriber as the datum. The datum may be permanently fixed or the height gauge may have provision to adjust the scale, this is done by sliding the scale vertically along the body of the height gauge by turning a fine feed screw at the top of the gauge; then with the scriber set to the same level as the base, the scale can be matched to it. This adjustment allows different scribers or probes to be used, as well as adjusting for any errors in a damaged or resharpened probe.

- 2. Current researches in image encryption techniques suggest using chaotic systems. But, one-dimensional (1D) chaotic schemes have drawbacks like small key space and weak security. This paper proposes a novel chaotic image encryption scheme based on two-dimensional (2D) logistic map. The 2D logistic map has more complex chaotic behaviors with respect to 1D logistic map like basin structures and attractors. The proposed scheme is based on permutation-substitution network and offers good confusion and diffusion properties in stream and block ciphers both. It encrypts plaintext image into random-like ciphertext image by generating the pseudorandom sequences from logistic map. The key schedule algorithm translates a binary encryption key to initial values and system parameters used in the 2D logistic map. This scheme uses 256 bit long cipher key for encryption/decryption. Experimental result indicates that the proposed scheme is secure against known cryptanalytic attacks and offers superior performance compared to existing chaotic image encryption schemes. 2www.icgst.com http://www.icgst.com/paper.aspx?pid=P1151351311 Secure Image Encryption using Two Dimensional Logistic Map Abstract
