Insider threats are one of the most damaging threats to modern systems. The ubiquity of cybersecurity problems related to insider threats promoted various solutions over the years. However, effective solutions are undermined by mathematical algorithms and host-based event driven techniques that...
A multi-objective energy efficient and flexible data center design has been of interest for all in the industry that are familiar with data center costs. A survey of 416 CIO's conducted by the CIO Data center Strategies Survey, suggested that the data center operating costs are steady at 25% of...
Systems engineers are faced with the challenge of adhering to broad systems engineering policies, while simultaneously tailoring systems engineering processes to meet the unique challenges facing their projects. Tailoring is often performed ad hoc, and determining which stages, steps, and...
Developing nations are poised to spend billions on information and communication technology (ICT) innovation in 2020. A study of the historical adoption of ICT in developing nations has indicated that their adoption patterns do not follow typical technology innovation adoption models. This study...
The U.S. healthcare system is the largest and most complex system worldwide. Many aspects of it necessitate major reforming to improve the quality of care and efficiency, reduce redundancies, and to restructure the existing cost structure. The Health Information Exchange (HIE) was initiated in...
In a 2007 memorandum, John Young, Under Secretary of Defense at that time, mandated the use of “competitive prototyping” strategies prior to the System Design and Development phase (Young, 2007). Department of Defense Instruction 5000.02 also includes considerations for prototyping in the...
There are significant challenges involved in regulating the growing commercial human spaceflight industry. The safety of the crew and passengers should be protected; however, care should be taken not to overburden the industry with too many or too stringent, or perhaps inapplicable,...
Effects of Geographic and Demographic Dispersion on the Performance of Systems Engineering TeamsGlobalization and the increasing complexity of systems require collaboration across multidisciplinary teams. Systems Engineering (SE) teams are often geographically and demographically dispersed; such...
This dissertation presents research that focuses on efficient allocation of defense resources to minimize the damage inflicted on a spatially distributed physical network such as a pipeline, water system, or power distribution system from an attack by an active adversary. The allocation...
Every year, the Department of Defense (DoD) invests billions of dollars on the development of major defense acquisition programs. In return, many of these weapon systems have been plagued with cost overruns and schedule delays during the Engineering and Manufacturing Development phase. Under...
AbstractA Systems Engineering Framework for Implementing aSecurity and Critical Patch Management Process in Diverse Environments(Academic Departments' Workstations)Use of the Patch Vulnerability Management (PVM) process should be seriously considered for any networked computing system. The PVM...
Public and private organizations face the challenges of protecting their networks from cyber-attacks, while reducing the amount of time and money spent on Information Technology. Organizations can reduce their expenditures by reusing server, switch and router hardware, but they must use reliable...
The recent economic downturn has had global repercussions in all businesses alike. Competition is fierce and a survival of the fittest model is always present; fast delivery times and innovative designs ultimately translate into the enterprises' bottom line. In such market conditions, enterprises...
In 2008, the Government Accountability Office (GAO) performed a study on 11 Department of Defense (DoD) programs and compared how requirements were developed between DoD and private industry. The study found that the DoD did not follow good Systems Engineering practices when developing...
Around the world, renewable energy-generating systems (RES) have expanded dramatically in capacity and in energy generated. A variety of means have driven this expansion, including mandates to meet RES-based generation targets. Much of the literature has focused on improving technical aspects of...
The electromagnetic spectrum is a crucial asset for wireless technology innovation and for the industry's economy. The significance of the telecommunications industry's capital expenditures increases with the spectrum acquisition value in its primary market due to the scarcity factor, which is...
Summary of contributions of this study: This study contributes new knowledge regarding the prescriptive utility of business intelligence systems and explicit knowledge objects in evidence-based management, and proposes a framework to better facilitate the management of business intelligence...
