Requirements engineering is a fundamental component of systems engineering. This paper describes how, and where, cognitive engineering (specifically the Cognitive Work Analysis (CWA) framework) could be applied in requirements engineering. We introduce an existing RE toolkit, the ι* modeling framework, and compare it with the CWA framework. The paper concludes with an outline of opportunities t...

This is the story of a recent U.S. Supreme Court case on the use of cost-benefit analysis at the U.S. Environmental Protection Agency (EPA) for a regulation issued under the Clean Water Act (CWA). The case is Entergy Corp. v. Riverkeeper, Inc., et al. The case was not about the quality of the cost-benefit analysis, nor the fact that EPA conducted one, but whether EPA had CWA authority to base r...

‎‎in the data envelopment analysis (dea) the efficiency of the units‎ ‎can be obtained by identifying the degree of the importance of the‎ ‎criteria (inputs-outputs).in dea basic models‎, ‎challenges are zero‎ ‎and unequal weights of the criteria when decision‎- ‎making units are‎ ‎evaluated‎. ‎one of the strategies applied to deal with these problems‎ ‎is using common weights of the each input...

Over 75,000 antitachycardia devices (ATDs) have been implanted since initial Food and Drug Adrninistra-tion approval in 1985 and have yielded dramatic survival rates. These devices, although life-saving, rely principally on simple measures of the heart rate for arrhythmia detection. The ATDs are highly sensitive, but their low specificity of diagnosis results in episodes of inappropriate therap...

The performance of the units is defined as the ratio of the weighted sum of outputs to the weighted sum of inputs. These weights can be determined by data envelopment analysis (DEA) models. The inputs and outputs of the related (Decision Making Unit) DMU are assessed by a set of the weights obtained via DEA for each DMU. In addition, the weights are not generally common, but rather, they are ve...

At present time most system engineers do not have access to cognitive work analysis knowledge or training in terms that they could understand and apply in the system design process. This may lead to specifying systems requirements that do not account for cognitive strengths and limitations of the prospective users. This paper proposes integration of cognitive work demands in the systems enginee...

Time-domain analysis of intraventricular electrogram morphology during ventricular tachycardia (VT) and sinus rhythm or atrial fibrillation (SR/AF) has been proposed as a method for increasing the specificity of pathological tachycardia detection by antitachycardia devices. However, few studies have validated the use of such analysis with statistical methods. When statistical methods have been ...

Football is one of the most popular and exciting sports fields throughout the world. Today, in addition to the result, the number of goals and points, attraction and quality of the played matches are important for club management staff, coaching staff, the players and especially the fans. Beside number of goals, there are different criteria such as successful passes, attacks, defenses, tackles ...
