Breast Cancer is among the top five causes of cancer death and topmost cause among women worldwide. The early diagnosis through simple, non-invasive and inexpensive screening can provide great deal of aid especially for the poor people of Bangladesh. Making diagnostics measurement available to the widely geographically spread population in developing countries is a challenge which is unlikely t...

Time Sliced Optical Burst Switching is a proposed variant of optical burst switching, in which switching is done in the time domain, rather than the wavelength domain. This eliminates the need for wavelength converters, the largest single cost component of systems that switch in the wavelength domain. We examine some of the key design issues for routers that implement time sliced optical packet...

The burst aggregation strategy in Optical Burst Switching systems is a balancing act between delay to assemble the burst and efficiency in filling it. The longer the assembly time, the better the fill level. Slotted systems can simplify control and avoid very short and inefficient bursts but the slot assembly strategy becomes a critical issue particularly when service quality must be supported ...

introduction: evaluation of students’ learning in clinical education system is one of the most important and challenging issues that facilities in this field have been facing. the present study aimed to evaluate the role of feedback during evaluation in increasing emergency medicine residents’ clinical skills. method: the present experimental study was performed on all second year emergency med...

this article presents a transient model of a solar adsorption cooling system. a computer program has been developed to simulate the operation of a two bed silica gel- water adsorption cooling system as well as flat plate collectors and the hot water storage tank. this program is then utilized to simulate the performance of a sample solar adsorption cooling system used for cooling a set of rooms...

In this paper, a nonlinear control-system design framework predicated on a hierarchical switching controller architecture parameterized over a set of moving system equilibria is developed. Specifically, using equilibria-dependent Lyapunov functions, a hierarchical nonlinear control strategy is developed that stabilizes a given nonlinear system by stabilizing a collection of nonlinear controlled...

This paper presents the results of simulation and control experiments using a recently proposed method for real-time switching among a pool of controllers. The switching strategy selects the current controller based on neural network estimates of the future system performance for each controller. This neural-network-based switching controller has been implemented for a simulated inverted pendul...

atm switching systems are required to maintain ordering for cells within a given virtual circuit This is most commonly achieved using a switching system in which cells in a given virtual circuit are routed along a common path through the switch ing system This solution has the drawback that it can lead to signi cant virtual circuit blocking unless the switching network is engineered with a larg...

This study attempted to investigate the impact of teacher’s code-switching on the acquisition of a problematic grammatical structure, namely, object relative clauses, by intermediate EFL learners. Moreover, a secondary objective of the study was to determine the EFL learners’ attitudes and opinions regarding the effectiveness of teacher’s code-switching in their learning of a specific aspect of...

Mounting evidence suggests that category learning is achieved using different psychological and biological systems. While existing multiple-system theories and models of categorization may disagree about the number or nature of the different systems, all assume that people can switch between systems seamlessly. However, little empirical data has been collected to test this assumption, and recen...
