The development of reusable requirements and design artifacts often requires one to characterize families of problem and solution models. This paper presents a metamodeling approach to characterizing a family of models. A characterization is expressed as a Role Model that consists of roles that can be played by UML model elemets. In this paper we describe how a family of UML static structural d...

Threshold cryptography increases security and resilience by sharing a private cryptographic key over different devices. Many personal devices, however, are not suited for threshold schemes, because they do not offer secure storage, which is needed to store shares of the private key. We present a solution that allows to include devices without them having to store their share. Shares are stored ...

Marketing-mix plays an essential role in the competitive business environment. Marketing decision makers constantly need to monitor changes in the environment and organization to make necessary changes. Therefore, a knowledge management system is required to acquire, store, retrieve and use up-to-dated knowledge. Corporations also tend to look for systems assisting them in knowledge management....

This paper introduces a word boundary detection algorithm that works in a variety of noise conditions including what is commonly called the ‘cocktail party’ situation. The algorithm uses the direction of the signal as the main criterion for differentiating between desired-speech and background noise. To determine the signal direction the algorithm calculates estimates of the time delay between ...

When a driver starts a car, he doesn’t think about starting an intelligent analytics system; sometimes, that’s precisely what he’s doing. In the future, we will encounter intelligent systems more often as embedded analytics is added to applications such as automotive vision, security and surveillance systems, industrial and factory automation, and a host of other consumer applications. Texas In...

This study in 2004 and 2005 aimed to present the pattern of job stress among car manufacturing workers in one factory in the Islamic Republic of Iran, and to assess its relationship with occupational injuries. Data were collected from 608 male workers (508 at-risk general workers and 100 with injuries in the last year). Job stress was assessed by the Belkic occupational stress index. The preval...

Let's read! We will often find out this sentence everywhere. When still being a kid, mom used to order us to always read, so did the teacher. Some books are fully read in a week and we need the obligation to support reading. What about now? Do you still love reading? Is reading only for you who have obligation? Absolutely not! We here offer you a new book enPDFd japans software factories a chal...

Software modelers refactor their design models to improve design quality while preserving essential functional properties. Tools that allow modelers to check whether their refactorings preserve specified essential behaviors are needed to support rigorous model evolution. In this paper we describe a rigorous approach to analyzing design model refactorings that involve changes to operation specif...

In the world of software systems, the process of evolving is an essential one. If this process represents no challenge on small systems, it becomes unbearable if the size of the system exceeds a certain limit. Therefore, the need arises for software tools that can carry out the necessary transformations automatically. This paper addresses the possibility to detect spots within an object-oriente...

Factory farming continues to grow around the world as a low-cost way of producing animal products for human consumption. However, many of the practices associated with intensive animal farming have been criticized by public health professionals and animal welfare advocates. The aim of this essay is to raise three independent moral concerns with factory farming, and to explain why the practices ...
