Avalanche Hazard Mapping along Manali-patsio Road Axis (Himachal Pradesh, India) Using Advanced Geo-Informatics Techniques
Abstract: Avalanche occurrence is quite a hazardous and unpredictable natural phenomenon. A large number of factors that are associated with its occurrence make it quite difficult to assess hazard in hilly areas. There are two main groups of variables that define the avalanche hazard – meteorological conditions and terrain characteristics. Due to the stable nature along the time, terrain parameters are easier to map. The purpose of this work is to …

DTM Generation and Avalanche Hazard Mapping using Large Format Digital Photogrammetric Data and Geomatics Technique
Abstract: The main objective of the study is Digital Terrain Model (DTM) generation from aerial photogrammetric data and identify and map the potential avalanche prone zones in Manali region. Avalanche is a dynamic hazardous phenomenon in the snow-bound mountainous terrain. Mapping of avalanche prone terrain is crucial to minimize the avalanche hazard. Nowadays, airborne data capturing technology, such as large-format Photogrammetry, has opened new vistas for the mapping of complex and …

Algebraic Foundations of AES (Advanced Encryption Standard): Group Theory and Finite Field Applications in Symmetric Cryptography
Abstract: This paper presents a mathematical study of symmetric cryptographic algorithms, with a particular emphasis on the Advanced Encryption Standard (AES), which is one of the most widely used encryption schemes in modern security applications. The study highlights how abstract mathematical frameworks such as group theory, finite fields, and vector space concepts provide the foundation for the design, implementation, and analysis of AES. By approaching the algorithm from a mathematical perspective, …

Optimized Receivers for Underwater Visible Light Communication
Abstract: For uses like ocean exploration, environmental monitoring, and underwater data transfer, wireless communication under water is crucial. Conventional acoustic and radio frequency communication methods suffer from low bandwidth, high latency, and severe signal attenuation in underwater environments. With its high data rate and low propagation delay, Visible Light Communication (VLC) provides a promising alternative. In this work, an underwater VLC system is implemented using Light Emitting Diodes (LEDs) with intensity …

Design of Photonic Sensor for Driver Assistance
Abstract: AbstractA report from National Highway Traffic Safety Association, USA, states that 100000 police reported crashes are a result of driver fatigue. This figure would be quite mind boggling for developing nations, where work periods are usually extended without conducting detailed scrutiny. Sophisticated vehicles are equipped with sensors for assisting drivers and providing them with time-critical accident alerts. However, there is a need to develop cheap and reliable sensors for 24x7 …

Environment Degradation and Disaster Management in Gilgit-Baltistan
Abstract: The mountainous region of Gilgit-Baltistan (GB) has been impacted by excessive natural and human-induced hazards like landslides, earthquakes, floods, avalanches and rock falls etc. Weak institutions coupled with climate/environmental changes are some of the factors increasing vulnerability of communities living in GB. In this paper, an attempt has been made to highlight the increased vulnerability of GB to various disasters due to phenomenon of climate/environmental change and recommended a methodology …

Digital Elevation Model (DEM) Extraction using Google Earth and Terrain Zonum Solutions Online Tool
Abstract: Topographic data or DEM are commonly perceived as providing loaded information for various types of modeling. However, this information severely limited and most users rely on published topographic maps or DEM produced by government agencies. This paper proposes an alternative method of generating DEM by using online source of elevation data which is easier and free. Firstly, the location of the study area identified in Google Earth and marked using …
