Due to its versatility, flexibility and fast development, the modern Internet is far from being well understood in its entirety. A good way to learn more about how the Internet functions is to collect and analyze real Internet traffic. This paper addresses several major challenges of Internet traffic monitoring, which is a prerequisite for performing traffic analysis. The issues discussed will ...

The Swedish MultiG program addresses research issues in distributed multimedia workstation applications, including CSCW, and high-speed networks. This report treats some basic CSCW issues in a distributed design environment. We review and analyse relevant literature on system design and computer supported cooperation and discusses the basic issues: What is design?What is collaboration in design...

To detect and describe categories in a given set of utterances without supervision, one may apply clustering to a space therein representing the utterances as vectors. This paper compares hard and fuzzy word clustering approaches applied to ‘almost’ unsupervised utterance categorization for a technical support dialog system. Here, ‘almost’ means that only one sample utterance is given per categ...

This study is undertaken to compare some different flood routing models including wave models and numerical models in the real field. The results of the wave models included kinematic, diffusive and dynamic wave have already been compared using laboratory data. Lack of the data field and technical support has been causes of not be investigated in the real field. In this present paper, several n...

Many application domains make extensive use of spatial and temporal information. However, the numerical approaches employed by most software tools have limitations, particularly when information is vague or incomplete. To address this, alternative qualitative spatial and temporal reasoning (QSTR) methods have been developed, yet few applications have made significant use of these techniques. In...

In an arid country like Kuwait with harsh and hot climate conditions, the scarcity of fresh water supplies presents a serious threat to sustainable socio-economic development and growth. Kuwait is an oil rich country with capital abundance and coastal locations enabled it to build desalination plants for fresh water production that is sold to the customers at highly subsidized prices. However, ...

Matt Spiegel for their comments and suggestions. Abstract This paper develops a model of optimal capital structure with stochastic interest rate which is assumed to follow a mean-reverting process. Closed-form solutions are obtained for both the value of the firm and the value of its risky debt. The paper finds that the current level and the long-run mean of the interest rate process play disti...

Finally, it sample of Illinois grain farms using the corshould be noted that the method developed rected ordinary least squares method. Instead here can be easily applied to farm data ...

This paper presents a comprehensive model intended to analyse general quality in telecommunications services centred in end users’ perceived quality (PQoS). The proposed model allows us to estimate the quality experienced by end users, while offering detailed conclussions regarding the responsibility of the different agents involved in the service provision. We overview the structure of the mod...

hospitals as the centers that consume the most resource of health system, based on their function have difference performance and efficiency. the purpose of this study was to assess the efficiency of ahvaz hospitals using data envelopment analysis (dea) method. this study is a descriptive-analytic study that assessed the efficiency of teaching and nonteaching hospitals in ahvaz using dea in 200...
