Investigating the Factors Affecting Delays in Infrastructure ProjectsDr. Amarjeet Singh
Time and expense overruns are regular occurrences in the construction industry all around the world but these are a major concern in developing countries such as India, and their consequences can be extremely harmful when public infrastructure projects are concerned. In India as per the MoS & PI report, as of October 2019, there were 552 delayed construction projects, and the mean time overrun in these 552 delayed projects is29.07 months. Many studies in the literature review previously, have concentrated on a variety of infrastructure risk management issues but there have only been a few studies that have looked into the overall dynamics of infrastructure and how a project's timeline can be affected by changing risk interactions. This article aids in the investigation of the variables and causes of construction delays in infrastructure projects.

Furthermore one way ANOVA analysis conducted to select factors that share agreement between the three groups.
A Study in Construction Delays of Residential StructuresIRJESJOURNAL
Abstract: Delays are one of the most common problem faced by the construction industry in India and around the world. Construction delays can be caused by several reasons which can be related to owner, design, labor or could be caused by some external factors such as bad weather. The delay in construction causes time overrun which implies that the project requires additional time for completion than originally anticipated. Time overrun in turn leads to cost overrun which causes huge monetary losses. This study focuses on finding out the most common causes of construction delays in Indian context. The study was carried out in South and Central Mumbai region. A questionnaire based survey was conducted based on 43 questions spread across 9 different categories. The findings were evaluated with Relative Importance Index technique. The aim of the study was to identify various causes of delays in construction and their importance.
An Investigation into the Delays in Road Projects in BahrainIJRES Journal
This research investigated the delays in road projects in Bahrain. It studied frequency and severity of delay’s causes, as well as frequency of delay’s effects in such projects. Forty seven causes were identified and classified by responsibility into six groups. A field survey was conducted through a questionnaire including 36 contractors, 24 consultants and 84 engineers working at Ministry of Works (MOW). The researcher concluded that there are many causes of delay related to contractors such as the improper planning and scheduling. One of the major causes related to the owner, i.e. MOW is delay in decision making. The main problems related to consultants are due to lack of experience. Moreover, cost and time overruns were two of the most frequent effects of delay.
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. 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.
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.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
