The occurrence of crude oil fouling in heat exchangers is a critical problem in the petroleum industry. It is the formation of impurities known as foulants that adhere to the surface of the heat exchanger which reduces its heat transfer capacity and increases the force required for the crude oil...
This Praxis describes a method for improving the accuracy of Use Case Point (UCP) effort estimation for software development projects. The thesis for the research is that an emergent factor exists in software development projects that is not considered in the UCP process. This emergent factor is...
Due to federal mandates, there is an increasing demand to advance renewable energy in the District of Columbia (D.C.) to deliver power. Utilities must find ways to achieve objectives while avoiding costly alternative compliance payments. In 2016, the District of Columbia’s Renewable Portfolio...
Locating children missing from state care quickly is critical for their safety and overall wellbeing. This research was conducted to evaluate the time it takes to establish the team of teams, or human systems of system, to search for a missing child. Specifically, the time it takes for social...
As airborne systems become more complex and highly-integrated, greater effort is required to demonstrate that systems operate as intended. The design and verification processes outlined in DO-178B and DO-254 are based on requirements. The system development practice recommended in ARP4754 expands...
The future of developing nations – both in terms of opportunities and challenges – is tied to the security of the information communications and technology (ICT) infrastructure. As many developing nations increase reliance on ICT to enable economic growth, they fail to commit an equivalent level...
Information Technology incident ticket prolonged resolution times means increased support costs for the IT organization and leads to dissatisfied users. The purpose of this study is to identify the factors that are causing this high-resolution time. A Six Sigma DMAIC (Define, Measure, Analyze,...
The nature of cyber security vulnerabilities has become more and more complex and the volume of vulnerabilities has become more overwhelming. The reporting and collection of vulnerability data has not stemmed the tidal wave of cyber security vulnerabilities This research performs analysis of the...
IT spending worldwide is projected to continue its growth, whereby using new technologies has become a significant factor in success rates of many companies. Moreover, IT projects are becoming more complex and more difficult to manage, as they involve uncertainty in terms of objectives, project...
This praxis seeks to determine the employee engagement drivers line managers can impact. By focusing on drivers that are linked to employee engagement, IT line managers can increase employee engagement. The existing literature on employee engagement is sourced from academia, industry, internal...
Project Managers in the construction industry need to implement changes on the way they manage complex projects to increase efficiency and stay ahead of the competition. One of these changes is the implementation of Agile, a set of principles developed from software development which focuses on...
The agile methodology is the incremental, continuous development and delivery of software, providing a continuous stream of software solutions that meet the customer’s needs. The U.S. federal government has realized the advantages of this methodology and has decided to utilize this methodology in...
Crowdsourcing is an increasingly common method used for new product development in large engineering-focused companies. While effective at generating a large number of ideas, previous research has noted that there is not an efficient mechanism to sort ideas based on the sponsor's desired...
Software systems can become overly complex throughout the software development process, leading to increased error rates and failures. This praxis improves on the measurement of complexity, the first step in resolving this problem. Most software development technologies allow for incorporation of...
This praxis develops a new logistics optimized approach to improve utilization rates in the TNC model and provides an alternative to the predominant existing TNC model used by both Uber & Lyft, which has been found to be inefficient in providing modern transportation mobility services....
