This paper examines the relationship among disaster tolerant systems, Information Technology (IT) application operation and availability, and the executive level management visibility necessary for system operational success. The current state of disaster tolerant application systems is explored including an investigation into the reliability and survivability requirements necessary to achieve ...

Many different designs of total hip arthroplasty (THA) with varying performance and cost are available. The identification of those which are the most cost-effective could allow significant cost-savings. We used an established Markov model to examine the cost effectiveness of five frequently used categories of THA which differed according to bearing surface and mode of fixation, using data from...

Thin-film photovoltaic (PV) modules often suffer from a variety of parasitic resistive losses in transparent conductive oxide (TCO) and absorber layers that significantly affect the module electrical performance. This paper presents the holistic investigation of resistive effects due to TCO lateral sheet resistance and shunts in amorphous-silicon (a-Si) thin-film PV modules by simultaneous use ...

canceled, will generate the resources necessary to implement the new treatment, and whose cancellation will reduce community well-being by less than the incremental gain expected from the new treatment. Until both conditions are met researchers should not infer cost effectiveness or “value for the money” for particular therapies—a result prematurely suggested by van den Brink et al in their eco...

Total Cost of Ownership (TCO) remains a significant factor that influences Enterprise Resource Planning (ERP) strategies and decisions. While “total” costs can and should include a wide range of factors, recent Aberdeen research has shown that the cost of software, services, and maintenance are those which are most often measured and considered when evaluating software or measuring the Return o...

Raman scattering is a rare event. It is only the extreme brightness of a focused laser radiation that makes Raman spectroscopy practical. Thus, since the laser beam is not materially affected by the interaction, it should be possible to pass the same laser beam through a sample multiple times with little attenuation of the laser power. We have accomplished this by means of a probe design in whi...

The scattering properties of transparent conductive oxide (TCO) films into dielectric and semiconductor surrounding media are modeled and compared to experiment. The new approach is not only valid for smooth optical films but also for films with enhanced roughness in order to generate light trapping structures for thin film solar cells. ©2010 Optical Society of America.

We develop an empirical method to assess the degree of financial exposure associated with medical care spending among non-elderly U.S. households with employer-sponsored insurance. A key feature of this method is its simplicity – it only requires data on out-of-pocket (OOP) health care spending and total health care spending and does not require detailed knowledge of health insurance benefit de...

Your SAP environment is critical to business operations. Migrating your SAP systems to Oracle Solaris delivers the availability, performance, scalability, flexibility, and security you need for mission-critical operations, all at a lower total cost of ownership than other UNIX and Linux systems. And, Oracle ACS Lifecycle Migration Services and Oracle Migration Factory help you make the change q...

In Part I of this paper the development of allocated and incremental cost and revenue techniques was described. have become predominant. In contrast, methodologies for dealing with revenues, particularly incremental measures, are in their infancy. Part II of the paper describes the state-of-the-art for these methods. This review is explicitly not meant as a cookbook of methodology, and the read...
