An optical mouse uses light instead of a rolling ball to detect movement. It works by focusing light onto a surface, using a sensor to detect changes in light intensity caused by movement. The sensor processes this information and sends signals to the computer corresponding to the direction and distance moved. New technologies like lasers and image sensors have improved optical mice by increasing sensitivity and allowing them to work on any surface.
In this technology, light is passed through transmission channel as it is the fastest medium. It overcomes the defect of WI-FI as well. Transmission of data takes place through illumination. Using this, we can connect to several devices under a single LED light.
E-paper is a revolutionary material that can be used to make next generation electronic displays. It is portable reusable storage and display medium that look like paper but can be repeatedly written one thousands of times. These displays make the beginning of a new area for battery power information applications such as cell phones, pagers, watches and hand-held computers etc.
Like traditional paper, E-paper must be lightweight, flexible, glare free and low cost. Research found that in just few years this technology could replace paper in many situations and leading us ink a truly paperless world.

Wi-Vi or wireless vision is one of the most modern technologies which use wireless fidelity or Wi-Fi as the core principle. Basically, it deals with tracking and manipulation of Wi-Fi signals.
Wi-Vi is used to image the obstacles or solids behind any wall or obstructions. The most important advantage of this is it is completely wireless and no cables or wires are used. Hence it becomes more suitable for usage in mobile devices and other lightweight technologies. Wireless facility also allows it to use in armed force and other security agencies.
As we know that SOANR and RADAR uses the principle of transmission and reflected waves, the Wi-Vi which uses the same principle can be called as an adaptation of those. But it also posses several differences and simpler apparatus. We will see those modifications on the coming pages of the paper.
normal person can use computer efficiently but a disabled(deficiency of upper limbs) person cannot.
with this technology a disabled can access the computer mouse simply by his eye movements.

Gergely Debreczeni, Chief Scientist at AImotive, presents the "Distance Estimation Solutions for ADAS and Automated Driving" tutorial at the May 2019 Embedded Vision Summit.
Distance estimation is at the heart of automotive driver assistance systems (ADAS) and automated driving (AD). Simply stated, safe operation of vehicles requires robust distance estimation. Many different types of sensors (camera, radar, LiDAR, sonar) can be used for distance estimation, and different distance estimation techniques can be used with each type of sensor. Each type of sensor and technique has unique strengths and weaknesses. Debreczeni examines these techniques and their strengths and weaknesses, and shows how multiple techniques using different sensor types can be fused to enable robust distance estimation for a specific automated driving application.
The board can also be used to start the application development without a soldering because mounted by default nine-axis sensor. Therefore, it is suitable for Web developers and mobile app developers. That there is not even further the power supply and the terminal connection is to occupy one of the few ports on the laptop because you can with a single USB cable.
Water scarcity is the lack of fresh water resources to meet the standard water demand. There are two type of water scarcity. One is physical. The other is economic water scarcity.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

Maintaining high-quality standards in the production of TMT bars is crucial for ensuring structural integrity in construction. Addressing common defects through careful monitoring, standardized processes, and advanced technology can significantly improve the quality of TMT bars. Continuous training and adherence to quality control measures will also play a pivotal role in minimizing these defects.
Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.
