Biomedical Engineering Course Development for Health Care Delivery

A new program of courses in biomedical engineering has been initiated at Michigan Technological University, both at the graduate and undergraduate level. The rationale for the development of these courses stems from the rapid growth in technology which has permeated almost all areas of health care delivery. The major goals of each course are described in terms of 1) establishing a required level of technical competence and literacy in the field, 2) developing those communication skills that will typically be required of the students after graduation, and 3) developing a sense of challenge which will last the students beyond their formative years. The philosophy underlying the choice of topical content, course organization, and student evaluation are all considered within the broader framework of establishing a modern foundation which the student, as well as the industrial and clinical community, can readily appreciate and identify with.     

System of Systems Collaborative Formation

The formation of a system of systems from a collection of interdependent systems does so in response to a collaborative mechanism. The nature of the constituent systems that compose the system of systems is a paradox by which they maintain an autonomous behavior and yet join the collective in collaboration. A social function can describe the system of systems mechanism that considers the value of collaborative relationships, and stresses preferences for action rather than an independent action of the individual systems. The constituent systems of the system of systems balance the risk of belonging with that of autonomy. This decision dichotomy is an example of typical decision makers that must balance cost and risk against achieving goals in a satisficing environment. A process beginning with a global goal serves to construct a multicriteria decision process creating the set of alternatives representing choices forming a collective social function that binds the system of systems. A case study demonstrates a simple application of independent autonomous systems collaborating to affect a holistic response with positive results.

真空灭弧室中X射线对人体健康的影响

一般认为,在进行真空灭弧室的出厂耐压试验时不会产生危及人体健康的X射线,但这忽略了两个非常重要的因素,即过小的开距和较高的外施电压。为深入了解X射线对高压试验人员的影响,在不同情况下进行一系列模拟加压试验,并对生产线上大量真空灭弧室进行X射线释放量的监测,发现在高电压老炼过程中会释放出高水平的X射线,无论瞬时量还是累计量都已经远远超过标准中规定的要求。因此,在从事该项工作时,采取适当的防范措施是十分必要的。

Human Factor Aspects of Power System Flow Animation

This paper presents experimental results associated with human factor aspects of using animation to display electric power system flow information, including transmission line megawatt flow and power transfer distribution factor (PTDF) values. The paper's results are based on two experiments performed at the University of Illinois at Urbana-Champaign using electric power system students. The results indicate that animated motion of power system flows can be used successfully in displays to improve both the speed and accuracy of certain tasks. This effect was most apparent on displays showing PTDFs. However, the results also show that motion may not provide a clear advantage in the visualization of transmission line flows for uncomplicated analysis tasks.

Comparison of Centralized and Decentralized Systems in Power System Restoration

This paper proposes a multiagent approach to decentralized power system restoration for distribution system networks and presents a comparison of centralized and decentralized systems for power system restoration. Numerous studies have been conducted on power system restoration problems. From the viewpoint of system structures, this research can be divided into two categories: centralized systems and decentralized systems. In this study, we solve a power system restoration problem for a power distribution network by two different methods: mathematical programming (MIP) and the proposed multiagent‐based method (MAS). The proposed multiagent system consists of several distributing substation agents (DSAGs) and load agents (LAGs). An LAG corresponds to the customer load, and a DSAG supplies electricity to the LAG. From the simulation results, it can be seen that the proposed system can reach the right solution by making use of only local information and that the solution quality is better than that of the centralized system (MIP). This means that the proposed multiagent restoration system is a promising approach to larger scale distribution networks.
