Meshfree Galerkin approximations in both two and three dimensions have been used in simulations of dynamic shear band propagation in an asymmetrically impact-loaded prenotched plate. Failure mode switching and failure mode transitions, which have been reported experimentally, are replicated in numerical computations. For intermediate impact speed (25 m=s < V 6 30 m=s), the numerical results sho...

The concept of software failure mode and effects analysis (FMEA) has grown in attractiveness over recent years as a way of assessing the reliability of software. Like its hardware counterpart, software FMEA is immensely tedious for an engineer to perform, as well as being error-prone. This paper presents the implementation of a novel method for automating code-level software FMEA based on treat...

The knowledge about failures needed to solve distributed agreement problems can be expressed in terms of completeness and accuracy properties of failure detectors introduced by Chandra and Toueg. The accuracy properties they have considered restrict the false suspicions that can be made by all the processes in the system. In this paper, we deene \??accurate" failure detectors, whose accuracy pr...

Traditionally, failure detectors have considered a binary model whereby a given process can be either trusted or suspected. This paper defines a family of failure detectors, called accrual failure detectors, that revisits this interaction model. Accrual failure detectors associate to each process a real value representing a suspicion level. An important advantage of accrual failure detectors ov...

background: guidelines recommend that exercise training can be considered for medically stable outpatients with heart failure; thus, this study sought to determine the effect of exercise on quality of life in patients with heart failure. patients and methods : in this cross sectional study 160 patients were included and divided into 2 groups (n=80). intervention group performed the exercise (po...

in this paper, numerical simulation of frp composite cylinder tubes progressive crushing processes is conducted using ls-dyna. details on the numerical modeling strategy are given and discussed. it is found that triggers introduced in the numerical simulation can effectively model the bevel trigger at the end of the tubular specimens. it is also found that two-layer finite element model based o...

in this study, behavior of pin-loaded glass fiber reinforced with polyethylene laminated composites with different stacking sequence and different dimensions has been observed experimentally and stress analysis was performed using ansys software. the aim is to investigate stresses, failure strength and failure mode of composite laminates containing a pin loaded hole when the material exhibits l...

background: heart failure is a severe chronic disease and has a negative impact on the health-related quality of life (hrql). in addition to preventing disease progress, one of the important goals in heart failure treatment is to improve the patient’s quality of life. this study is aimed to compare three generic to specific quality of life instruments that are used in cardiac rehabilitation set...
