Modulation formats : Direct and External ModulationPRAJJWAL ROHELA
This document discusses different types of optical modulation techniques, including direct modulation and external modulation.

External modulation separates the light generation and modulation processes, where a continuous wave light source is modulated externally after generation. Some key advantages of external modulation are wider modulation bandwidth and better performance, though it is more complex and expensive. The document also covers modulation parameters, direct and analog modulation, limitations of direct modulation, and external modulation techniques like Mach-Zehnder and electro-absorption modulators.

Phenomena like Mach bands and simultaneous contrast demonstrate that perceived brightness depends on context rather than absolute intensity.

Digital image acquisition requires two main components: a physical sensing device that captures electromagnetic energy and converts it to an electrical signal, and a digitizer that converts the electrical signal to digital form. There are three main methods of image acquisition - using a single sensor, a line of sensor strips, or a 2D array of sensors. The most common modern approach is to use a 2D array of sensors, as found in digital cameras, which allows an entire image to be captured at once without requiring relative motion between the sensor and scene.

Images are discretized through sampling and quantization to create a digital image represented by a matrix of pixels with discrete intensity values. The document covers characteristics of the human visual system, image resolution, interpolation techniques, arithmetic operations on images like averaging, subtraction and multiplication, and how digital images are represented and stored in memory.
The document discusses basic relationships between pixels in digital images. It defines that a pixel has 4 horizontal and vertical neighbors, called 4-neighbors. It also has 4 diagonal neighbors, and together with the 4-neighbors they form the 8-neighbors of a pixel. Adjacency between pixels is defined based on 4, 8 or m-connectivity depending on pixel intensity values. Connectivity and paths between pixels are also described. Regions in an image are defined as connected subsets of pixels, and region boundaries are pixels adjacent to the complement of the region.

Multiple access methods like FDMA, TDMA, and CDMA are used to enable multiple users to access the channel simultaneously. Duplex systems can be simplex, half-duplex, or full-duplex depending on the direction of transmission.

Development of an Institutional App by adopting Android PlayIJMTST Journal
The whole information of any organization or an institution has to view in a hard file, or in website in the current circumstances. At the same time while searching any information it is very hard to access and takes a lot of time to search the particular website. Because of this, in order to overcome this problem a smart phone based application using Android can be used to make this process easier, secure and less error prone. The Android application is portable and can be easily installed and used on any mobile phones supporting Android OS. It also provides an interface which is easy to understand by the users and greatly helps in adapting to the use of this application. Android is an open source Linux based system developed by Google, and mostly aimed at mobile handsets and other portable devices. In short, we will be using them to complete our daily job. One computer program that falls into this category is the Android Application for College. This College application provides a wide range of useful information which split into several abilities to do things. These include: academics, news, events, facilities, and all the college details. Users can install this application in their android mobile to view all of these college details and make use of it. Android application for college provides one attractive environment where you can manipulate information about college easily. Through this the students, Faculty members get all the information in their hand. It is software which is helpful for students as well as the college authorities. The main principle behind the need of Android app for college is easy supervision of the Institute. This software can help us to explore all the activities happening inside the college. The courses offered in the college, the latest news and updates that will be updated in the college website in timely wise manner, the various events took place in our college along with their details, pictures etc.. Our application also provides details of various NSS activities conducted in our college such as Blood donation, various social awareness camps.

STUDY THE EFFECT OF RESPONSE REDUCTION FACTOR ON RC FRAMED STRUCTUREIRJET Journal
This study examines the effect of response reduction factors (R factors) on reinforced concrete (RC) framed structures through nonlinear dynamic analysis. Three RC frame models with varying heights (4, 8, and 12 stories) were analyzed in ETABS software under different R factors ranging from 1 to 5. The results showed that displacement increased as the R factor decreased, indicating less linear behavior for lower R factors. Drift also decreased proportionally with increasing R factors from 1 to 5. Shear forces in the frames decreased with higher R factors. In general, R factors of 3 to 5 produced more satisfactory performance with less displacement and drift. The displacement variations between different building heights were consistent at different R factors. This study evaluated how R factors influence

Embedded machine learning-based road conditions and driving behavior monitoringIJECEIAES
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.
