The EDF+ (European Data Format Plus) is a flexible and open source data format created in order to store and exchange biomedical signals. it is known worldwide and used by a large variety of specialists in the area. EDF+ signals have been subjected to many researches of clinical interest amongst diagnosing and for treatment of diseases related to sleeping disorders. Nevertheless, more complete and user-friendly tools, which use these signals, are yet too few in the market. This paper presents a new tool developed in order to read and analyze EDF+ signals, focusing in the area of sleep disorders. it includes several features, such as organizing signal channels through previous montage customizations, sleep stage bars and graphics for analyzing the quality of sleep (hypnograms). it provides easiness in the whole process of interpretation and scoring of sleep events in polysomnography exams. The software development used the C++ language, due to its great versatility and efficiency, using Visual Studio Community 2013? as the integrated Development Environment (iDE). Moreover, it implements many Digital Signal Processing (DSP) techniques, for instance, its own set of digital filters. This paper presents an application of Polysomnography analysis software and suggests a modification on the way to interpret the EDF+ standard and its usage.

Classical structural reliability analysis of intact ship hulls is extended to the case of ships with collision or grounding *** water load distribution and residual bending moment capacity are included as random variables in the limit state *** probability density functions of these random variables are defined based on random damage parameters given by the Marine Environment Protection Committee of the international Maritime Organization,while the proposed reliability formulation is consistent with international recommendations and thus may be valuable in the development of rules for accidental limit *** methodology is applied on an example of an Aframax oil *** proposed approach captures in a rational way complex interaction of different pertinent variables influencing safety of damaged ship structure.

Background: Acute myocardial infarction is a leading cause of death worldwide nowadays and treatment of choice is primary percutaneous coronary intervention (PCi). No reflow is a complication that increases mortality and morbidity post intervention and one of its predictors is platelet lymphocyte ratio. Aim of Study: To assess relation between admission platelet to lymphocyte ratio (PLR) and angiographic reflow after primary PCi in acute ST elevation myocardial infarction (STEMi). Patients and Methods: This is a prospective study that was conducted from May 2017 to May 2018 at Cardiology Department, Menoufia University Hospital. Sixty patients presented with ST-elevation myocardial infarction who were eligible for primary PCi were enrolled in the study. According to TiMi flow post intervention, patients were arranged into 2 groups: Group 1 (Normal Reflow) included thirty patients with post intervention TiMi flow iii and Group 2 (NO Reflow) included thirty patients with post intervention TiMi flow (0, i, ii). Comparison between both groups was done regarding platelet lymphocyte ratio (PLR). Result: PLR was significantly higher in patients with coronary no reflow than in patients with normal reflow with a P-value of , timing interval between onset of chest pain to time of intervention and thrombus grading was significantly higher in patients with no reflow than in patients with normal reflow. Conclusion: Pre-intervention PLR is an independent predictor of slow flow/no reflow following PPCi in patient with acute STEMi.

interval constraint propagation (iCP) algorithms allow to solve problems described as constraint satisfaction problems (CSP). iCP has been successfully applied to vehicle localization in the last few years. Once the localization problem has been stated, a large class of iCP solvers can be used. This paper compares a few iCP algorithms, using the same experimental data, in order to rank their performances in terms of accuracy and computing time.
