BACKGROUND Understanding the mechanisms conditioning development of chronic kidney disease (CKD) is still a challenge. The aim of this study was to evaluate the activity of the intrarenal nitric oxide (NO) pathway in the context of sensitivity or resistance of different animal strains to the development and degree of renal failure. MATERIAL AND METHODS Two rat strains were used: Wistar (WR) and...

Accessing information in multimedia databases encompasses a wide range of applications in which spoken document retrieval (SDR) plays an important role. In SDR, a set of automatically transcribed speech documents constitutes the files for retrieval, to which a user may address a request in natural language. This article deals with two probabilistic aspects in SDR. The first part investigates th...

Software defined radio (SDR) mobile terminals that can access multiple wireless communication systems are the trend of the future. An SDR wideband mobile terminal must be capable of high-speed data processing and low power consumption. Reconfigurable processors with these features show promise for SDR wideband mobile terminals. We have developed a signal processing board using a reconfigurable ...

Observational studies assessing causal or non-causal relationships between an explanatory measure and an outcome can be complicated by hosts of confounding measures. Large numbers of confounders can lead to several biases in conventional regression based estimation. Inference is more easily conducted if we reduce the number of confounders to a more manageable number. We discuss use of sufficien...

~ b s m c t the functions of software-defined radio (SDR) can be changed by changing its software. Therefore, many security problems that have never been seen in the conventional fixed wireless terminals will arise. We assess the security issues of the SDR system by taking the distribution model of SDR terminal software into account. A universal security architecture for the SDR systems is prop...

Abstract. In this paper, we consider a fundamental problem in modern digital communications known as multi-input multi-output (MIMO) detection, which can be formulated as a complex quadratic programming problem subject to unit-modulus and discrete argument constraints. Various semidefinite relaxation (SDR) based algorithms have been proposed to solve the problem in the literature. In this paper...

In this research we present Bidirectional exact pattern matching algorithm [20] in detail. Bidirectional (BD) exact pattern matching (EPM) introduced a new idea to compare pattern with Selected Text Window (STW) of text string by using two pointers (right and left) simultaneously in searching phase. In preprocessing phase Bidirectional EPM algorithm improved the shift decision by comparing righ...

Chen et al. in 2004 proposed a new hierarchy structure, called the enhanced pyramid network (EPM, for short), by replacing each mesh in a pyramid network (PM, for short) with a torus. Recently, some topological properties and communication on the EPMs have been investigated or derived. Their results have revealed that an EPM is an attractive alternative to a PM. This study investigates the node...

In recent years, improvement of software process is increasingly gaining attention. However, its practice is very difficult because coherent data collection and utilization of the collected data require considerable experience with software process improvement. In this paper, we describe our empirical approach to software engineering and introduce Empirical Project Monitor (EPM). Collecting dat...
