Mobile technologies and more precisely apps have disrupted technology scenario. Bring your own application (BYOA) is a new trend that has emerged after the “bring your own device” (BYOD) vogue. However, and in spite of its intrinsic benefits, the trend presents also several caveats and Enterprise app stores are seen as a way to tackle these risks. In this paper, authors present ModEAS, a system...

Social reformers such as John Stuart Mill and John Dewey have long expressed concern about a tension between democratic principles and organizational practices that appear undemocratic.' More recently, a substantial body of academic literature advocating changes in organizations to make them more democratic has been produced.2 Change has been advocated on a variety of normative grounds. In a no...

Error is an inevitable part of life and cannot be completely eliminated, but it can be minimized. A root cause analysis is a technique for understanding the systematic error causes that is involved beyond a person or people to implement an errors and including field and environmental causes of errors when occur in this situation too. An important factor of an error occurrence is a root cause (c...

The paper analyzes, in brief, various on-line condition monitoring techniques for rotating electrical machines. The different failure mechanisms of electrical machines and several monitoring techniques are analysed. The advantages, disadvantages and reliability of each technique are underlined. A few of the current state of the art techniques are reviewed by surveying the latest developments in...

Survivable systems are modelled abstractly as collections of services supported by any of a set of configurations of components. Reconfiguration to restore services as a result of component failure is viewed as a kind of “flow” analogous to information flow. We apply Meadows’ theorem on datset aggregates to characterize the maximum safe flow policy. For reconfiguration, safety means that servic...

When designing aerospace systems, it is essential to provide crucial failure information for failure prevention. Failure Modes and Effects types of analyses and prior engineering knowledge and experience are commonly used to to determine the potential modes of failures a product might encounter during its lifetime. When new products are being considered and designed, this knowledge and informat...

The nose bridge between the inlet valve and exhaust valve is the most fragile part on the cylinder head. Fatigue crack is the major failure mode. It is necessary to analyze the structure strength and reliability (SSR) of this zone. In this paper, a three-dimensional (3D) model for a engine cylinder head is built up using Pro/Engineer wildfire 2.0, and the 3D FEM analysis of the SSR is carried o...

Modern embedded systems contain complex structures, as they are composed of many subsystems. Maintaining such systems requires collaboration between the engineers who designed them and the engineers who analyzed the failures in them. In this paper we present our proposed visual platform ESSAVis, a 2Dplus3D environment, to help both kinds of engineers in understanding the failure mechanisms of s...
