In this paper, a CFD analysis on the bare hull form of submarines or torpedoes for minimizing the resistance is represented. There are several parameters in submarine form design which the most important parameter is resistance. All operational characteristics of submarines are related to the resistance, related required power and then, underwater speed and range. Other parameters are only ment...

The provisioning of quality of service by means of statistical multiplexing has been an alluring research idea for the last decade of teletraffic research. In this paper we question the efficiency of statistical bitrate service which is the standardized representation of this operational mode for ATM networks. Our argument is that the amount of information needed about a traffic source in order...

We calculate the transfer function of an optical receiver composed by a photodiode and a FET input operational amplifier as a current to voltage converter. According to the theory of low-pass filters, the receiver bandwidth and quality factor are here analytically evaluated, proposing design solutions and their related sensitivity to eventual parameter fluctuations. We exemplify the combined ac...

We propose an abstract operational model of a highly adaptive distributed resource management architecture (DRMA) for network enabled operations in large-area surveillance. The architectural design of DRMA is described in terms of a distributed abstract state machine. As part of this work, we present the specification and design of a Dynamic Configuration Manager (DCM) that actively maintains t...

We propose a method to prepare and verify spatial quantum superpositions of a nanometer-sized object separated by distances of the order of its size. This method provides unprecedented bounds for objective collapse models of the wave function by merging techniques and insights from cavity quantum optomechanics and matter-wave interferometry. An analysis and simulation of the experiment is perfo...

In this paper, we evaluate the performance of an ad-hoc network architecture, investigating the effect of various design and operational parameters on the blocking and dropping probabilities. In particular, we study the improvement in the network coverage due to the multi-hop routing feature. Furthermore, the effect of limiting the path length on the network performance is studied, showing that...

Recently the superior performance of the PolyMAX modal parameter estimation method using frequency response functions was demonstrated. The method can be implemented in a very similar way as the industry standard polyreference (time-domain) least-squares complex exponential method: in a first step a stabilisation diagram is constructed containing frequency, damping and participation information...

The recently finalized Basel II Capital Accord requires banks to adopt a procedure to estimate the operational risk capital charge. Under the Advanced Measurement Approaches, that are currently mandated for all large internationally active US banks, require the use of historic operational loss data. Operational loss databases are typically subject to a minimum recording threshold of roughly $10...

financial statement of a company is a reflection of the operational and financial position of a company. the comparative analysis of two companies similar in nature, size, work, location and objectives etc., facilitates an understanding of the operational and financial soundness of the companies. the kingdom of saudi arabia is aiming for rapid industrialization in its economy. sahara petrochemi...
