The infrastructure sectors of developed countries have direct and indirect interdependencies. These interdependencies make national infrastructures extremely prone to the cascading effects of perturbations or failures. A negative event that reduces the operability of one infrastructure sector rapidly spreads to other sectors and back to the original sector in a feedback loop, amplifying the neg...

Light Detection and Ranging (LIDAR) is a system which can directly collect three-dimensional coordinate information of ground point and laser reflection strength information. With the wide application of LIDAR system, users hope to get more accurate results. Boresight error has an important effect on data accuracy and thus, it is thought that eliminating the error is very important. In recent y...

Methyl and ethyl esters were prepared from camelina [Camelina sativa (L.) Crantz] oil by homogenous base-catalyzed transesterification for evaluation as biodiesel fuels. Camelina oil contained high percentages of linolenic (32.6 wt.%), linoleic (19.6 wt.%), and oleic (18.6 wt.%) acids. Consequently, camelina oil methyl and ethyl esters (CSME and CSEE) exhibited poor oxidative stabilities and hi...

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...
