Oil-reservoir management using measurements and control techniques have been in use by oil and gas industries to improve the production and maintenance of the existing oil reservoirs. In the course of this project the applications of UWB radar systems and techniques to acquire near real-time information about the oil reservoir conditions are studied. Various oil reservoir structures such as oil...

This paper aims to reveal the mechanism of Collateralized Debt Obligations (CDOs) and how CDOs extend the current global financial crisis. We first introduce the concept of CDOs and give a brief account of the development of CDOs. We then explicate the mechanism of CDOs within a concrete example with mortgage deals and we outline the evolution of the current financial crisis. Based on our overv...

Autonomous vehicles are a new and exciting challenge for the automation of transport systems. The scope of applications covers heavy traffic control from construction sites, fork-lifting trucks in factories, switcher locomotives in stations and so on. This article refers to the problem of backing up a model-truck with a trailer to a ramp. The concrete solution to this problem requires the integ...

The paper presents an analysis of the effect of magnetic fields of power frequency generated by heavy-current electric equipment on the environment. The results of computation and measurements of the magnetic field in the vicinity of power busducts are included. Possible hazards are considered that result from the effects of the magnetic field on workers present in the vicinity of busducts as w...

In the renewal risk model, several strong hypotheses may be found too restrictive to model accurately the complex evolution of the reserves of an insurance company. In the case where claim sizes are heavy-tailed, we relax independence and stationarity assumptions and extend some asymptotic results on finite-time ruin probabilities, to take into account possible correlation crises like the one r...

Within the framework of these studies, issues related to modification composition heavy concrete based on a polydisperse binder with complex modifier and its influence formation structure properties cement stone, as well hardened concrete, are considered. The purpose study is substantiate possibility obtaining effective for irrigation drainage construction improved indicators operational in ter...

The dynamic characterization of concrete is fundamental to understand the material behavior in case of heavy earthquakes and dynamic events. The implementation of material constitutive law is of capital importance for the numerical simulation of the dynamic processes as those caused by earthquakes. Splitting tensile concrete specimens were tested at strain rates of 10(-7) s(-1) to 10(-4) s(-1) ...

A weakness of many interactive visual programming languages (VPLs) is their static representations. Lack of an adequate static representation places a heavy cognitive burden on a VPL’s programmers, because they must remember potentially long dynamic sequences of screen displays in order to understand a previously-written program. Building upon the cognitive dimensions developed for programming ...
