Review on modeling of coal blends for prediction of coke qualityJorge Madias
The operation of blast furnaces with coal/natural gas injection requires high coke quality. For lowest coke cost while keeping the necessary coke quality, the choice of coals and the formulation of the blend is a very important issue. A widely utilized tool for blend design is modeling, preceded by coal characterization and followed by pilot oven testing. In this paper, the development of models is reviewed, based on public literature. Three main stages are taken into account, form the sixties to current times..
Evaluation Performance ofan Annular Composite Fin by UsingMATLAB ProgrammingIJERA Editor
The aim of this project is analysis the efficiency ratio in an annular fin by the variation of heat transfer coefficient for any surface condition by using MATLAB software to calculate the base fin efficiency and the coated fin efficiency by the variation of heat transfer coefficient, radius ratio and base fin thickness of an annular fin and compare the coating fin efficiency to base fin efficiency. If the heat transfer coefficient is 50W/m2K the increase efficiency ratio is 10.46 – 28.02% for zinc coating fin from the literature but the MATLAB result is 9.3 - 25.54% , the gain efficiency ratio at thicker base fin (d=0.001m) is 11.72%, at the thinner base fin (d=0.0002m) is 33.57% from the literature but the MATLAB result is 7.45% (d=0.001m) and 32.14% (d=0.0002m) for zinc coating fin and the gain efficiency ratio at thicker base fin (d=0.001m) is 11.92%, at the thinner base fin (d=0.0002m) is 33.61% from the literature but the MATLAB result is 7.51% (d=0.001m) and 32.16% (d=0.0002m) for zinc alloy coating fin.
Evaluation of mechanical properties of retrogression and reaged al 7075 alloy...eSAT Journals
Abstract The metal matrix composites offers a spectrum of advantages that are important for their selection and use as structural materials. A few such advantages are high strength, high elastic modulus, high toughness and impact resistance, low sensitivity to changes in temperature or thermal shock, high surface durability, low sensitivity to surface flaws, high electrical and thermal conductivity, minimum exposure to the potential problem of moisture absorption resulting in environmental degradation and improved machinability with conventional metal working equipment. The aim of the present study is to investigate the mechanical properties of Silicon Carbide particulate (SiCp) reinforced Aluminum matrix composite after retrogression and re-aging. Aluminum 7075 alloy with 10%, 15% and 20% SiCp were studied. Keywords: Retrogression and Re-aging, Aluminum 7075 alloy, heat treatment.
Solar thermal control of building integrated phase change materials an experi...eSAT Journals
Abstract
In the present paper, we study experimentally the thermal behavior of phase change material (PCM) for thermal control of indoor
applications. The experimental setup consists of two full scale identical concrete cavities, situated in Faculty of Sciences Aïn
Chock in Casablanca- Morocco (33°36'N, 07°36'W). The first cavity incorporates paraffinic phase change material with melting
temperature of 22 °C and second cavity is built with alveolar bricks. The test cells are equipped by set of thermocouples and heat
flux meters connected to data logger. Thermal analysis for the two cubicles was conducted. The results show that inner
temperature swings decreases remarkably in the cavity with PCM with temperature minima 3 °C upper to the case without PCM.
On the other hand, there is time shift between PCM cavity and the reference cavity temperature oscillations. The integration of the
phase change material on the roof of the building reduces the temperature of internal walls as it has good thermal inertia. When
PCM panel covered the roof, solar heat transmission is reduced. This significantly reduces the ambient temperature of the cell.
This demonstrates the ability of PCM to increase the thermal comfort of buildings.

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.

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.

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.
