Third generation mobile systems are gradually being deployed in many developed countries in hotspot areas. However, owing to the amount of new infrastructures required, it will still be some time before 3G is ubiquitous, especially in developing countries. One possible cost effective solution for deployments in these areas is to use High Altitude Platforms (HAPs) (Collela et al., 2000; Djuknic ...

At least 40 QTL studies have been reported in pigs (Andersson et al., 1994 a,b; Andersson-Eklund et al., 1998; Beeckmann, 2000; Bidanel et al., 2001; Cassady et al., 2001; Casas-Carrillo et al, 1997; Ciobanu et al, 2001; De Koning et al., 1999; De Koning et al., 2000; De Koning et al., 2001a,b; Desautes et al., 2002; Edfors-Lilja et al., 1998; Geldermann et al., 1999; Grindflek et al., 2001; Ha...

Automatic detection and tracking of moving object is very important task for humancomputer interface (Black & Jepson, 1998), video communication/expression (Menser & Brunig, 2000), and security and surveillance system application (Greiffenhagen et al., 2000) and so on. Various imaging techniques for detection, tracking and identification of the moving objects have been proposed by many research...

Investigating nozzle’s orifice flow is challenging both experimentally and theoretically. This paper focuses on simulating flow inside diesel injector nozzle via Ansys fluent v15. Validation is performed with experimental results from Winkhofler et al (2001). Several important parameters such as mass flow rate, velocity profiles and pressure profiles are used for this validation. Results includ...

Security is increasingly becoming a critical focus in information systems projects. With more networks, mobility, and telecommuting, there is an increased need for an assessment of the technical and security risks. These risks if realized can have devastating impacts: interruptions of service, data theft or corruption, embezzlement and fraud, and compromised customer privacy. The software risk ...

Functional neurosurgery is the only surgical alternative treatment for patients with Parkinson’s disease (PD) (Agid, 1999; Benzzouz & Hallett, 2000; Beric et al., 2001; DeLong & Wichmann, 2001; Dowsey-Limousin et al., 2001; Hariz & Fodstad, 2002; Kopper et al., 2003; Krause et al., 2001; Vesper et al., 2002). Dopamine deficiency in Parkinson’s disease leads to increased neuronal activity. Regul...

Variable selection via penalized estimation is appealing for dimension reduction. For penalized linear regression, Efron, et al. (2004) introduced the LARS algorithm. Recently, the coordinate descent (CD) algorithm was developed by Friedman, et al. (2007) for penalized linear regression and penalized logistic regression and was shown to gain computational superiority. This paper explores...

Does Gender Matter? I read with interest the report by Bartlett et al describing a linear relationship between millimeter carotid stenosis, as measured on CT angiography, and derived percent stenosis. According to the “Materials and Methods” section, the authors did not evaluate their patient population on the basis of sex. Tartaglino et al, however, reported that men and women differ in the av...

Although there has been much discussion of belief change (e.g., [Gärdenfors, 1988; Spohn, 1988]), goal change has not received much attention. In this paper, we propose a method for goal change in the framework of Reiter’s [2001] theory of action in the situation calculus [McCarthy and Hayes, 1969; Levesque et al., 1998], and investigate its properties. We extend the framework developed in Shap...

The development and implementation of evidence-based guidelines appears to be one of the most promising and effective tools for improving quality of care (Grol 2001). To improve the quality of physiotherapeutic care for patients with low back pain, evidence-based clinical practice physiotherapy guidelines were developed (Bekkering et al 2003; Table 1). The content of these guidelines connects w...
