In this paper, a 7-level Diode Clamped Multilevel Inverter (DCMLI) is simulated with three different carrier PWM techniques. Here, Carrier based Sinusoidal Pulse Width Modulation (SPWM), Third Harmonic Injected Pulse Width Modulation (THIPWM) and Modified Carrier-Based Space Vector Pulse Width Modulation (SVPWM) are used as modulation strategies. These modulation strategies include Phase Dispos...

nowadays, standard seems to be very important and necessary in all aspects of the life including reference services in libraries. this article is to survey the role of standards in electronic reference services and also considers some sample application instructions which are presented in the dupont- university. by the end, the guide for digital reference services which is called ifla is presen...

Nitrification in the hyporheic zone of Sycamore Creek, a Sonoran Desert stream, was examined, focusing on the association between respiration and nitrate production. Subsurface respiration in Sycamore Creek is highest in regions of hydrologic downwelling where organic matter derived from the stream surface is transported into the hyporheic zone. Similarly, nitrification was closely related to h...

We are investigating the fusion of edge information into Markov Random Fields (MRF) region growing based image segmentation. Our goal is to segment the image in a way that would take edge information into consideration. This is achieved by modifying the energy minimization process so that it would penalize merging regions that have real edges in the boundary between them. Experimental results c...

Sequence comparison is a fundamental task in pattern matching. Its applications include file comparison, spelling correction, information retrieval, and computing (dis)similarities between biological sequences. A common scheme for sequence comparison is the longest common subsequence (LCS ) metric. This paper considers the fully incremental LCS computation problem as follows: For any strings A,...

This paper describes the implementation of a Stub Generation system targeted specifically at C++. It enables distributed C++ applications to be constructed in a straightforward manner with minimal programmer assistance. The system does not require the use of an auxiliary interface definition language but instead processes existing C++ header files to maximise transparency. The generated code ex...

abstract objective: homeostasis model assessment of insulin resistance (homa-ir) is a simple and practical method for estimation of insulin resistance (ir), but a reliable reference interval (ri) of homa-ir is needed to deduce the threshold level to define ir. this ri has been controversial in different populations and even more divergent when considering factors like age, gender and body mass ...

The finite element method is employed for the flexural-torsional linear buckling analysis of beams of arbitrarily shaped composite cross-section taking into account generalized warping (shear lag effects due to both flexure and torsion). The contacting materials, that constitute the composite cross section, may include a finite number of holes. A compressive axial load is applied to the beam. The...
