A Review of Multi Resonant Slotted Micro Strip Patch Antenna (MPA) for IMT, W...IJEEE
In this paper, a stacked multi resonant slotted micro strip patch antenna (MPA) has been proposed which is suitable to be used for GSM, WLAN standard and WiMAX applications. The antenna has been designed using substrate of FR4 material. In the designed stacked antenna, substrates having different thickness has been used. The bottom stack of designed antenna has a radiating patch of circular shape and the patch on the upper stack has rectangular shape and is flexible in nature. The antenna has a feed line which is connected to circular patch to feed power to the antenna. The feed line has to be of suitable width to match the antenna impedance with port impedance of 50 ohms. The designed antenna has a defected ground structure in order to improve the antenna performance. The antenna performance has been measured in terms of antenna parameters such as impedance bandwidth (GHz), Return loss (dB), antenna impedance (ohms), VSWR and Directivity (dBi). The designed antenna results have been simulated in CST Microwave Studio 2010. The practically designed antenna has been tested successfully by using Network analyzer E5071C. It has been observed that the practical results closely match with theoretical results.
Microstrip patch antennas are the most common form
of printed antennas. They became very popular due to their low
profile geometry, light weight and low cost. A Rectangular
Microstrip Patch Antenna with probe feed and substrate used is
Arlon AD260 has the relative permittivity of which is 2.6 is
designed and simulated using high frequency structure simulator
(HFSS). All the Parameters of this microsrip patch Antenna such
as bandwidth, S - parameter, Reflection loss and VSWR has been
found and plotted. The main objective of this work is to consider
the reactive loading effect on the patch and its effect towards the
improvement of the antenna characteristics, particularly the
radiation characteristics in principle plane (E and H) is
examined. As per theoretical approach reactive loading creates
either capacitive loading or inductive loading. Due to this effect
the antenna performance may be degraded or enhanced in terms
of efficiency, isolation, gain, impedance matching etc. The results
of this designed antenna are compared with the existing Micro
strip antenna

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.

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.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.
