When testing multimedia software applications, we need to overcome important issues such as the forbidding size of the input domains, great difficulties in repeating non-deterministic test outcomes, and the test oracle problem. A statistical testing methodology is proposed. It applies pattern classification techniques enhanced with the notion of test dimensions. Test dimensions are orthogonal p...

In competing risks data, missing failure types (causes) is a very common phenomenon. In a general missing pattern, if a failure type is not observed, one observes a set of possible types containing the true type along with the failure time. Dewanji and Sengupta (2003) considered nonparametric estimation of the cause-specific hazard rates and suggested a Nelson-Aalen type estimator under such ge...

A concrete block retaining wall is supported by its weight. This structure has some advantages, including lower construction costs, a water-permeable that produces less water pressure behind the wall, and more flexible because it can follow ground's contours. Rankine's theory usually used to design this wall. According theory, failure pattern forms an angle of 450 + • /2 with horizontal plane. ...

background: the alteration of th1 and th2 cytokine levels is the subject of controversy in pleural effusions caused by malignancy, a situation that favors a th2 immune response. objective: to examine the different levels of il-4 and il-10 (th2 cytokines), and il-2 and interferon-γ (ifn-γ) (th1 cytokines) in malignant and non-malignant pleural effusions. method: the cytokine levels in pleural fl...

One of the common failure modes of thin cylindrical shell subjected external pressure is buckling. The buckling pressure of these shell structures are dominantly affected by the geometrical imperfections present in the cylindrical shell which are very difficult to alleviate during manufacturing process. In this work, only three types of geometrical imperfection patterns are considered namely (a...

background: renal complication of leptospirosis is common and its clinical manifestations vary from urinary sediment changes to acute renal failure. the aim of this study was to determine the final outcome of renal involvement in leptospirosis. methods: this longitudinal prospective study included all serologically confirmed cases of leptospirosis with evidence of renal failure. all patients we...

BACKGROUND Aimed to elucidate the characteristics of the spectra of superior venae cavae (SVC) in respiratory cycles in patients with right heart failure. METHODS The spectra of SVC of 30 patients with right heart failure and 30 paired healthy subjects were recorded through right supraclavicular fossa view. The profiles of spectra of superior venae cavae were observed, and peak velocity and v...
