Information security professionals have to assess risk in order to make investment decisions on security measures. To investigate whether professionals make such decisions optimally, we conduct an online experiment and survey measuring risk attitudes of security professionals. Participants were asked to state their willingness-topay to avoid a series of losses-only lotteries and to make choices...

We examine the optimization of NLC parameters at 500, 1000, and 1500 GeV c.m. energy for speci c classes of physics processes, in particular, top and stop pair production, and W-W scattering processes. Our focus is on optimizing the luminosity spectrum, while maintaining or improving machine operability. Presented at Worldwide Study on Physics and Experiments with Future Linear e+eColliders, Ap...

The assessment of inoperability of bronchial carcinoma by angiocardiography has received little attention in this country, and it is the purpose of this paper to discuss the value of this investigation by analysing our results in 31 cases at Leicester Chest Unit. Since the introduction of angiocardiography by Robb and Steinberg in 1938 many authors have described its use in the differential dia...

-In a clinical investigation of postoperative survival after primary surgery for stomach cancer, 390 patients were registered since 1974. The potential prognostic parameters examined within the first days of hospitalization for primary resection included age of the patients, operability, tumour extension (TNM classification) and tumour stages I-IV (UICC). Statistical treatment of the data revea...

The Jet Propulsion Laboratory (JPL) is developing a 5 12x640-format, dual broadband, Quantum Well Infrared Photodetector (QWIP) focal plane array (FPA) for an imaging interferometer. This is a new type of imaging interferometer which is based on special Fourier-transform spectroscopy, scans interferograms digitally without moving any optical components. It is stable enough to measure fluctuatin...

The aim is to improve the operability of an advanced demonstration platform incorporating reflexive teleoperated control concepts developed on a mobile robot system. The robot is capable of autonomously navigating in semi-structured environments. Reflexive tele-operation mode employs the robot extensive onboard sensor suite to prevent collisions with obstacles when the human operator assumes co...

Personal health records (PHRs) are a rapidly expanding area in medical informatics due to the belief that they may improve healthcare delivery and control costs of care. To truly understand the full potential value of a technology, a cost analysis is critical.However, little evidence exists on the value potential of PHRs, and a cost model for PHRs does not currently exist in the literature.This...
