In a cooling gas of rigid particles interacting with a constant coefficient of restitution, groups of particles within the gas may experience an infinite number of collisions in a finite time. This singularity, named inelastic collapse, is a shortcoming of the mathematical model, and it hampers the efforts of simulating a freely evolving, cooling granular system. After a brief review of previou...

In today's world with companies operating in a global business environment. Most enterprises, and especially the SMEs, lack the necessary business culture, technical and non-technical infrastructure and economic flexibility in order to efficiently adjust to the environment of a B2B integration framework. This paper proposes an Enterprise Integration Assessment Framework (EIAF) and its support s...

The scarf framework as presented [2] offers the basic equations for training SCRFs. We propose to extend the framework with Empirical Bayes Risk training or Empirical Training Error optimization, which are better correlated with the error metric one seeks to optimize, than the conditional log-likelihood normally used. Second, SCRFs are (marginalized) exponential models over segmented sequences....

The selection and adoption of open source ERP projects can significantly impact the competitiveness of organizations. Small and Medium Enterprises have to deal with major difficulties due to the limited resources available for performing the selection process. This paper proposes a framework for evaluating the quality of Open Source ERP systems. The framework is obtained through a specializatio...

The response of the water table of an intertidal salt marsh in NW England has been investigated. During neap tides, water seeps upward from the underlying sand-silt-clay interface. This effect continues as the marsh is overtopped during spring tides but is then dwarfed by penetration of water downward from the surface. Under “typical conditions” the delay between high water in the river and max...

MIDDLE EAST JOURNAL ✮ VOLUME 58, NO. 2, SPRING 2004 Dhufar, the southern region of the Sultanate of Oman, displays a tremendous diversity in its social structure, rather surprising for an area so small. While the people of the coastal plain and the inland Najd are Arabic-speaking, the mountain highlands of the region are home to various non-Arabic speaking communities. Brief descriptions of the...

We analyze a simple model for running: a three-dimensional springloaded inverted pendulum carrying a point mass (3D-SLIP). Our formulation reduces to the sagittal plane SLIP and horizontal plane lateral leg spring (LLS) models in the appropriate limits. Using the intrinsic geometry and symmetries and appealing to the case of stiff springs, in which gravity may be neglected during stance, we der...

Many of Florida’s springs and spring runs are enriched in nitrate due to broad-scale contamination of groundwater supplies. This observation fosters two primary and interrelated concerns regarding the effects of nutrients on flora and fauna in spring systems. High nitrate concentrations can affect fauna directly through toxicity. In addition, high nitrate concentrations can promote eutrophicati...
