The most expensive project in human history is the International Space Station (ISS); it has reached $160+ billions in total expenses. Currently, the lifespan of the ISS has been exceeded, and the spacecraft operations is projected for a minimum of 10 years. However, due to its aging technology,...
An Easy-to-Implement Model to Determine the Percentage of Wake Energy from a Vessel Reaching the Shoreline Across the country, cities are considering implementing or have implemented ferry service as a method of transportation. According to the U.S. Department of Transportation, there were...
The majority of steel manufacturers within the United States have employed electric arc furnaces (EAFs), which melt raw materials, for the production of steel. The raw material used in EAFs is referred to as steel, or ferrous, scrap. There are many different grades of ferrous scrap, which are...
Forecasting of resource utilization in large cloud computing systems is essential to maintain high-quality service and fulfill service level agreements to ensure cost-effectiveness and profitability. Accurately forecasting long-term resource utilization can be challenging, as it is dynamic and...
This research study presents the concept of DevOps (or development and operations) performance clusters to measure DevOps teams performance, based on three metrics, two agility metrics (delivery lead time and deployment frequency) and a stability metric (mean time to recover). It uses a...
In the package delivery industry, competitive advantage is changing with the evolution of customer expectation. The United States Postal Service (USPS) started with the delivery of letters, but had to restructure its company when the mailing of letters began to decrease, while simultaneously the...
The US Air Force (USAF)’s goal is to achieve aircraft availability (AA) rates similar to those of the commercial airline industry. Improving AA rates while reducing operations and maintenance (O&M;) costs is a major challenge for the USAF. This Praxis research identifies field-level components...
An engineering change (EC) is an alteration made to a system that has beenreleased following a system design process. EC propagation is a series of ECs occurringdue to dependencies among components of a product. ECs can consume up to 50% of theoverall engineering efforts during development of a...
Uncertainty arising from immature technology is a major cause of programmatic risk. Programs continue to have poor results in terms of cost and schedule performance. This research seeks to improve program performance during the system development phase by better understanding the risks of...
Current management and technical structures of the electric power system in Togo have shown their limits. Togo continues to suffer from limited access to electric power and endemic electric power shortages resulting in the slow-down of the country’s socio-economic development. For over 43 years,...
The problem of forecasting emerging technologies (FET) has attracted the attention of researchers in the patent-analysis community because it provides a starting point for organizations to introduce radical technology change or a new product or engage in a merger and acquisition. Many FET methods...
Oil and Gas Exploration and Production (E&P;) projects routinely experience cost overruns and delays, with about 64% of new projects exceeding their budgets and almost 75% completed behind schedule partly as a result of non-optimal project designs1. Owing to the highly complex and heterogeneous...
The last thirty years have seen multiple DoD acquisition programs with significant cost and schedule overruns. This paper posits that the primary driver of schedule overruns is the difficulty of “inventing on a schedule” by undertaking risky technology development efforts within a Major Defense...
Electronic waste (e-waste) is a growing economic opportunity for informal recycling operations in developing countries, while it is a major health and environmental concern for the developed world. Currently, only 25% of gold in e- waste is recovered successfully through informal recycling...
The federal government currently collects information for the Information Technology (IT) Projects in which it invests, but it does not apply this information to more accurately predict the performance of these projects. As a result, project managers within the federal government are not...
Contract chemical manufacturers spend resources on development trials that have errors due to incomplete knowledge transfer from the customer. These errors waste engineering resources and can result in lost business. A technology transfer program was proposed as a solution to reduce the number of...
Valve Original Equipment Manufacturers (OEMs) in the United States are facing increasing pressure to offer products capable of competing with other local and low-cost country industry players, forcing them to continuously lower prices and shorten delivery dates. At the same time, operations and...
Electricity has become an invaluable commodity for the rest of humanity such that nations irrespective of their classification in the world economy will find it difficult to function without it’s reliable supply. For nations such as the United States and the rest of the developed world,...
Although the traditional intrusion detection problem has been well studied with the release of the KDD’99 and NSL-KDD datasets, recent intrusion detection has expanded to include wireless 802.11 networks and Industrial Control Systems & Supervisory Control and Data Acquisition (ICS/SCADA)...
Resilience theory plays a vital role in the practical design of modern engineered resilient systems composed of cyber-physical systems and components having interdependencies intended to make the entire system robust. In this paper, the percolation-based metric is applied to measure the...
Renewable energy generation, including solar photovoltaics, will be an increasing part of the power supply to the utility grid. Due to the intermittent and variable nature of the power supply from photovoltaics, energy storage systems will need to be applied to the utility service grid to allow...
Resilience is explained as an entity’s capacity to survive and recover from disruptions. Approaches to design resilient systems are in growing demand; however, there have been few demonstrations for measuring and quantifying systems resilience. This research presents a Resilience Analysis...
