Core network capacity planning is the process of ensuring that sufficient bandwidth is provisioned such that the committed core network service-level agreements can be met. The best practices described in this paper collecting demand matrices, determining overprovisioning factors, and running simulations are the basis of the design principles for the Cisco TM MATE TM portfolio, especially (from...

We present an incremental copying garbage collector for the heap in WAM-based Prolog systems. We describe a heap layout in which the heap is divided in a number of equal-sized blocks. Other changes to the standard WAM allow to garbage collect these blocks independently from each other. Independent collection of heap blocks is the basis of our incremental algorithm. Compared to other copying col...

Improper disposal of household unwanted medications (UMs) is an emergency problem around the world that adversely affects the sustainability of the environment and human’s health. However, the current disposal practices, mainly based on advertising and collecting status, are unsatisfactory in most countries and regions. Thus, some scholars proposed an alternative disposal practice that is to pr...

Grids are becoming more and more dynamic, running parallel applications on large scale and heterogeneous resources. Explicitly stopping a whole distributed application is becoming increasingly difficult. In that context, there is a strong need to free resources a soon as they become useless, leading to automatic termination, using distributed garbage collecting techniques. We propose in this pa...

Automatic provenance collection describes systems that observe processes and data transformations inferring, collecting, and maintaining provenance about them. Automatic collection is a powerful tool for analysis of objects and processes, providing a level of transparency and pervasiveness not found in more conventional provenance systems. Unfortunately, automatic collection is also difficult. ...

The aerosol collection efficiencies of water droplets and ice crystals are compared based on the concept of equivalent geometrical kernel K* which is the geometrical sweep-out volume per unit time by the collector. It is thought that the comparison based on this quantity reveals the real difference of the aerosol collecting abilities of different collectors and sheds lights on the precipitation...

Informatics and AI claim that the word is made of objects organized into classes (taxonomies, ontologies,...). In this paper, we explore an other idea: we structure our material relationships by collecting objects within collections, which are never as static as classes.

Distributed collector solar fields are spatially distributed engineering systems which aim at collecting and storing energy from solar radiation. They are formed by mirrors which concentrate direct incident sun light in a pipe where an oil able to accumulate thermic energy flows. From the control point of view, the objective consists of making the outlet oil temperature to track a reference sig...

A 69-year-old man consulted our department regarding further examination because abnormal venous ectasia of the basal vein of Rosenthal (BVR) was accidentally found on magnetic resonance imaging. Angiography revealed a dural arteriovenous fistula (DAVF) in the left sphenoid wing; the fistula was supplied by the ophthalmic artery and the middle meningeal artery. Venous drainage from the fistula ...
