Ocean wave energy and its uses in generating electricityDr. Ved Nath Jha
This document discusses ocean wave energy and its potential uses and challenges. It describes how ocean waves are a renewable source of energy generated by wind. While wave energy could help meet electricity demand, there are technological and environmental challenges to overcome. These include efficiently converting wave motion to electricity, designing structures that can withstand storms and corrosion, and reducing costs. Further research is needed to better understand the feasibility and impacts of wave energy technologies for specific locations like remote Alaskan communities. Overall, the document examines the viability and opportunities of harnessing ocean wave power, but notes the development challenges that must still be addressed.

Extinction ratio and its effect on the nonlinearity in optical fiber networks...Dr. Ved Nath Jha
Extinction ratio is an important factor in optical fiber networks that affects nonlinearity and signal quality. A higher extinction ratio leads to better signal quality and lower bit error rates over longer transmission distances. The document presents simulation results showing that with an extinction ratio of 7dB, a transmission distance of 50km achieved a higher quality factor and lower bit error rate than 100km. Increasing the extinction ratio to 30dB improved the quality factor and bit error rate at both 50km and 100km, but the performance degraded more at 100km compared to 50km. Therefore, for a given extinction ratio, shorter fiber lengths provide better performance in optical communication systems.

STUDY ON FIBER GRATINGS AND ITS CHARACTERIZATIONDr. Ved Nath Jha
Good potential uses in fiber and fiber lasers have been seen through Random Fiber Gratings (RFGs). However, a quantitative link has never been studied between the RFG's randomness and spectral reaction. This paper first experimentally characterizes two RFGs of varying degrees of randomness by optical frequency reflectometry (OFDR). The high degree of randomness indicates that the grating intensity is limited and the strength variations in spatial domain are large. The experimental findings show. Study establishes the theoretical basis for the optimization configuration and implementation of the long-term fiber grating in the area of fiber optics sensing and communication.
DEVELOPMENT OF OPTICAL PARAMETER CALCULATIONS OF THE PROBES IN WATERDr. Ved Nath Jha
This document describes the development of optical parameter calculations for probes used in water sensing. Three probes (a, b, c) of varying nanoparticle size were developed and their plasma and collision wavelengths were calculated based on experimental measurements in water and air. The probes showed decreasing collision wavelength but nearly constant plasma wavelength with increasing nanoparticle size. Models were developed to calculate output intensity based on the dielectric constant of the surrounding medium. Distinct dips in output intensity correlated with different dielectric components when mixtures were tested, showing ability to detect multiple impurities simultaneously. The probes function best for dielectric constants between 1.4-2.0 and silver nanoparticles provide sensitivity towards targeted impurities in water quality monitoring.
AN INTRODUCTION TO BASIC PHENOMENA OF PLASMA PHYSICSDr. Ved Nath Jha
Plasma is a set of neutral and charged particles which reveals a number of collective behaviors. The very
long range coulomb forces enable the charged particles in plasma to work together with one another
simultaneously. The study of plasma is actually a really ancient area of investigation in plasma physics
and it remains to be among the vital fields due to the crucial role of its in most plasma uses including
plasma processing, fabrication of semiconductor systems, etching, etc. except the presence of just ions
and electrons, the plasma in many instances, has a number of other species of ions like negative ions
which impact the complete plasma behaviour. Within this paper we study about the fundamental ideas of
plasma physics.

This document discusses dispersion in optical fibers and its effects. It makes the following key points:
1. Dispersion occurs when the phase velocity of a wave depends on its frequency, causing different wavelength components of a pulse to travel at different group velocities. This leads to pulse broadening.
2. In optical fibers, dispersion arises from the wavelength-dependent mode field diameter and refractive index differences between the core and cladding. This causes different propagation speeds for different wavelengths.
3. Dispersion limits the rate at which data can be transmitted over fibers by causing pulse broadening that leads to overlapping pulses at high bit rates. This dispersion-induced limitation affects the maximum usable bit rate and transmission distance.

Optimizing Gradle Builds - Gradle DPE Tour Berlin 2024Sinan KOZAK
Sinan from the Delivery Hero mobile infrastructure engineering team shares a deep dive into performance acceleration with Gradle build cache optimizations. Sinan shares their journey into solving complex build-cache problems that affect Gradle builds. By understanding the challenges and solutions found in our journey, we aim to demonstrate the possibilities for faster builds. The case study reveals how overlapping outputs and cache misconfigurations led to significant increases in build times, especially as the project scaled up with numerous modules using Paparazzi tests. The journey from diagnosing to defeating cache issues offers invaluable lessons on maintaining cache integrity without sacrificing functionality.
CHINA’S GEO-ECONOMIC OUTREACH IN CENTRAL ASIAN COUNTRIES AND FUTURE PROSPECTjpsjournal1
The rivalry between prominent international actors for dominance over Central Asia's hydrocarbon
reserves and the ancient silk trade route, along with China's diplomatic endeavours in the area, has been
referred to as the "New Great Game." This research centres on the power struggle, considering
geopolitical, geostrategic, and geoeconomic variables. Topics including trade, political hegemony, oil
politics, and conventional and nontraditional security are all explored and explained by the researcher.
Using Mackinder's Heartland, Spykman Rimland, and Hegemonic Stability theories, examines China's role
in Central Asia. This study adheres to the empirical epistemological method and has taken care of
objectivity. This study analyze primary and secondary research documents critically to elaborate role of
china’s geo economic outreach in central Asian countries and its future prospect. China is thriving in trade,
pipeline politics, and winning states, according to this study, thanks to important instruments like the
Shanghai Cooperation Organisation and the Belt and Road Economic Initiative. According to this study,
China is seeing significant success in commerce, pipeline politics, and gaining influence on other
governments. This success may be attributed to the effective utilisation of key tools such as the Shanghai
Cooperation Organisation and the Belt and Road Economic Initiative.

Using recycled concrete aggregates (RCA) for pavements is crucial to achieving sustainability. Implementing RCA for new pavement can minimize carbon footprint, conserve natural resources, reduce harmful emissions, and lower life cycle costs. Compared to natural aggregate (NA), RCA pavement has fewer comprehensive studies and sustainability assessments.
