Face Recognition Technology
Face Recognition TechnologyShashidhar Reddy Face recognition technology uses digital images and video frames to automatically identify or verify a person. It works by comparing selected facial features from an image to a facial database containing 80 landmarks on each face, such as distance between eyes, width of nose, and jaw lines. This is done using local feature analysis algorithms to encode faces and create unique numerical codes, or "face prints", that can be matched against large databases. While face recognition provides convenience over other biometrics like fingerprints, it has disadvantages such as an inability to distinguish identical twins and potential issues with database searching speeds. However, decreasing costs are leading to more widespread deployment of this technology in applications like access control, advertising, and retail point-of-sale systems.

Devanagari Character Recognition
Devanagari Character RecognitionPulkit Goyal The presentation will describe an algorithm through which one can recognize Devanagari Characters. Devanagari is the script in which Hindi is represented. This algorithm
could automatically segment character from the image of Devenagari text and then recognize them.
For extracting the individual characters from the image of Devanagari text, algorithm segmented the image several
times using the vertical and horizontal projection.
The algorithm starts with first segmenting the lines separately from the document by taking horizontal projection and then the line
into words by taking vertical projection of the line. Another step which is particular to the separation of
Devanagari characters was required and was done by first removing the header line by finding horizontal projection
of each word. The characters can then be extracted by vertical projection of the word without the header line.
Algorithm uses a Kohonen Neural Netowrk for the recognition task. After the separation of the characters from the
image, the image matrix was then downsampled to bring it down to a fixed size so as to make the recognition
size independent. The matrix can then be fed as input neurons to the Kohonen Neural Network and the winning neuron is
found which identifies the recognized the character. This information in Kohonen Neural Network was stored
earlier during the training phase of the neural network. For this, we first assigned random weights from input neurons
to output neurons and then for each training set, the winning neuron was calculated by finding the maximum
output produced by the neurons. The wights for this winning neuron were then adjusted so that it responds to this
pattern more strongly the next time.

Arnaud Collard, Technical Leader for Embedded AI at 7 Sensing Software, presents the “Cutting-edge Memory Optimization Method for Embedded AI Accelerators” tutorial at the May 2024 Embedded Vision Summit.
AI hardware accelerators are playing a growing role in enabling AI in embedded systems such as smart devices. In most cases NPUs need a dedicated, tightly coupled high-speed memory to run efficiently. This memory has a major impact on performance, power consumption and cost. In this presentation, Collard dives deep into his company’s state-of-the-art memory optimization method that significantly decreases the size of the required NPU memory. This method utilizes processing by stripes and processing by channels to obtain the best compromise between memory footprint reduction and additional processing cost.
Through this method, the original neural network is split into several pieces that are scheduled on the NPU. Collard shares results that show this technique yields large memory footprint reductions with moderate increases in processing time. He also presents his company’s proprietary ONNX-based tool that automatically finds the optimal network configuration and schedules the subnetworks for execution.

Development of portable automatic number plate recognition (ANPR) system on R...IJECEIAES ANPR system is used in automating access control and security such as identifying stolen cars in real time by installing it to police patrol cars, and detecting vehicles that are overspeeding on highways. However, this technology is still relatively expensive; in November 2014, the Royal Malaysian Police (PDRM) purchased and installed 20 units of ANPR systems in their patrol vehicles costing nearly RM 30 million. In this paper a cheaper alternative of a portable ANPR system running on a Raspberry Pi with OpenCV library is presented. Once the camera captures an image, image desaturation, filtering, segmentation and character recognition is all done on the Raspberry Pi before the extracted number plate is displayed on the LCD and saved to a database. The main challenges in a portable application include crucial need of an efficient code and reduced computational complexity while offering improved flexibility. The performance time is also presented, where the whole process is run with a noticeable 3 seconds delay in getting the final output.

Prediction of Unconfined Compressive Strength of Expansive Soil Amended with ...
Prediction of Unconfined Compressive Strength of Expansive Soil Amended with ...Journal of Soft Computing in Civil Engineering Expansive soils (ES) have a long history of being difficult to work with in geotechnical engineering. Numerous studies have examined how bagasse ash (BA) and lime affect the unconfined compressive strength (UCS) of ES. Due to the complexities of this composite material, determining the UCS of stabilized ES using traditional methods such as empirical approaches and experimental methods is challenging. The use of artificial neural networks (ANN) for forecasting the UCS of stabilized soil has, however, been the subject of a few studies. This paper presents the results of using rigorous modelling techniques like ANN and multi-variable regression model (MVR) to examine the UCS of BA and a blend of BA-lime (BA + lime) stabilized ES. Laboratory tests were conducted for all dosages of BA and BA-lime admixed ES. 79 samples of data were gathered with various combinations of the experimental variables prepared and used in the construction of ANN and MVR models. The input variables for two models are seven parameters: BA percentage, lime percentage, liquid limit (LL), plastic limit (PL), shrinkage limit (SL), maximum dry density (MDD), and optimum moisture content (OMC), with the output variable being 28-day UCS. The ANN model prediction performance was compared to that of the MVR model. The models were evaluated and contrasted on the training dataset (70% data) and the testing dataset (30% residual data) using the coefficient of determination (R2), Mean Absolute Error (MAE), and Root Mean Square Error (RMSE) criteria. The findings indicate that the ANN model can predict the UCS of stabilized ES with high accuracy. The relevance of various input factors was estimated via sensitivity analysis utilizing various methodologies. For both the training and testing data sets, the proposed model has an elevated R2 of 0.9999. It has a minimal MAE and RMSE value of 0.0042 and 0.0217 for training data and 0.0038 and 0.0104 for testing data. As a result, the generated model excels the MVR model in terms of UCS prediction.

Filters for Electromagnetic Compatibility Applications
Filters for Electromagnetic Compatibility ApplicationsMathias Magdowski In this lecture, I explain the fundamentals of electromagnetic compatibility (EMC), the basic coupling model and coupling paths via cables, electric fields, magnetic fields and wave fields. We also look at electric vehicles as an example of systems with many conducted EMC problems due to power electronic devices such as rectifiers and inverters with non-linear components such as diodes and fast switching components such as MOSFETs or IGBTs. After a brief review of circuit analysis fundamentals and an experimental investigation of the frequency-dependent impedance of resistors, capacitors and inductors, we look at a simple low-pass filter. The input impedance from both sides as well as the transfer function are measured.
"The Enigmas of the Riemann Hypothesis" by Julio Chai
"The Enigmas of the Riemann Hypothesis" by Julio ChaiJulio Chai In the vast tapestry of the history of mathematics, where the brightest minds have woven with threads of logical reasoning and flash-es of intuition, the Riemann Hypothesis emerges as a mystery that chal-lenges the limits of human understanding. To grasp its origin and signif-icance, it is necessary to return to the dawn of a discipline that, like an incomplete map, sought to decipher the hidden patterns in numbers. This journey, comparable to an exploration into the unknown, takes us to a time when mathematicians were just beginning to glimpse order in the apparent chaos of prime numbers.
Centuries ago, when the ancient Greeks contemplated the stars and sought answers to the deepest questions in the sky, they also turned their attention to the mysteries of numbers. Pythagoras and his followers revered numbers as if they were divine entities, bearers of a universal harmony. Among them, prime numbers stood out as the cornerstones of an infinite cathedral—indivisible and enigmatic—hiding their ar-rangement beneath a veil of apparent randomness. Yet, their importance in building the edifice of number theory was already evident.
The Middle Ages, a period in which the light of knowledge flick-ered in rhythm with the storms of history, did not significantly advance this quest. It was the Renaissance that restored lost splendor to mathe-matical thought. In this context, great thinkers like Pierre de Fermat and Leonhard Euler took up the torch, illuminating the path toward a deeper understanding of prime numbers. Fermat, with his sharp intuition and ability to find patterns where others saw disorder, and Euler, whose overflowing genius connected number theory with other branches of mathematics, were the architects of a new era of exploration. Like build-ers designing a bridge over an unknown abyss, their contributions laid the groundwork for later discoveries.
