This paper presents an investigation into analysis of the causes of delays on Construction Projects in Kuwait according to opinion of engineers working in Kuwait. This is achieved through identification of the major causes of delays in the construction industry as reported in literature and using a questionnaire survey to collect the views of the various key players in the Kuwaiti construction industry. The data is analyzed and the views of the groups surveyed discussed and the relative importance index used to rank the causes of delays in the construction industry as per the questionnaire responses obtained. .It is found that the top 10 causes of delays in construction projects in Kuwait are as listed below. Using a lowest price bidding and tendering system Poor performance of the main contractor Inadequate experience or qualifications of main contractor’s staff Delay of payments from client to other parties Poor performance of subcontractors Shortage in the supply of general labour Frequent changes of subcontractors Delay in decision making by the client Poor management of subcontractors Conflict between the main parties to the contract Inappropriate methods used by the main contractor Proposals of ways to effectively prevent delays in the future construction projects managed in Kuwait construction industry were developed from the identified causes delay
The alarming rate of project delays in this country needs urgent attention and resolution as one project delay leads to another therefore affecting the growth of any economy or profit-making organization. This alarming rate would possibly go out of one’s hand if strategies are not put in place to curb these phenomena. The Objectives of this research is to critically identify and evaluate the setbacks or factors causing delays in completing projects on time and its effect. The study narrowed its arrows on Prime Ghana projects executed in the country and it was thus conducted with the usage of questionnaires to solicit for the required data for processing. Results from the study divulge that the actual sources of delays in project delivery are; Inadequate financial resources of clients, delays in honoring payment for work done, underestimation of project duration, poor communication between contracting parties, complexity, difficulties in accessing bank credit (client); change orders during construction and others. It was recommended that, initial proper planning and controlling is essential to the client to have proper action plan, procurement plan, and budget plan prepared before commencement of project. Payment schedule must be agreed by the parties involved. On the part of the contractor adequate knowledge of project management, principles, tools and techniques is required to reduce delays. Consultants must plan very well to ensure that contract processes are duly followed, thus approval of drawings, documentation, and other things to reduce variation during construction. They should monitor their assigned work very well by insisting that corrections are done at the appropriate time to reduce or avoid rework.

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.

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.
