This paper investigates the merits of the SR-VTCA (Stable Routing-Virtual Topology Capacity Adjustment) approach as a mechanism to find a beneficial trade-off between network stability and reduction in capital expenditures (CapEx). These are two main objectives for the entities that own the optical infrastructure, such as Network Operators (NOs), and those also acting as Internet Service Provid...

This paper describes ILP-PLAN, a framework for solving AI planning problems represented as integer linear programs. ILP-PLAN extends the planning as satisfiability framework to handle plans with resources, action costs, and complex objective functions. We show that challenging planning problems can be effectively solved using both traditional branchand-bound IP solvers and efficient new integer...

-The network standards organizations have left the assessment component of network management to the network administrator. While there are good reasons for doing so, we feel that this has unnecessarily left a void between network service management and the end user. Our research is motivated by this position. We present a network monitoring and assessment algorithm that bridges the gap that ex...

Purpose In our proton beam therapy center, we use imaging plates (IP) for dose verification of field matching in irradiation (called patch-field technique). this study, a polymer gel dosimeter, which can perform three- dimensional distribution measurement, was used as new tool the patch method corresponding to rectangular irradiation. Method The results measurements PAGAT dosimeter irradiate tw...

Multicast networking support is becoming an increasingly important technology area for both commercial and military distributed or group-based applications. The underlying delivery mechanism for IP multicast is presently the User Datagram Protocol (UDP) or raw IP packets. At present, these mechanisms provide a "best effort" delivery service. Best effort implies that IP packets are treated with ...

During the years 2000 and 2001, the Italian Ministry for University and Scientific Research funded four research projects covering various topics in the field of networking: IPPO (IP packet optical networks), NEBULA IP (Techniques for end-to-end quality of service control in multidomain IP networks), PLANET-IP (Planning IP networks), and RAMON (Reconfigurable access module for mobile computing ...

In the provision of multiservice network services, much attention has been focused on the use of usernetwork (UN) signalling. UN signalling plays an important role in connection-oriented networks. In such networks, it can be used for admission control, providing resource allocation (resource reservation), enabling new services, accounting information (for generating bills) as well as allow coll...

In order to examine the distribution of errors in different phrases in the Korean prosodic hierarchy, 12 native Korean speakers were recorded while producing tongue twisters. The resulting errors were categorized and their location coded with respect to the prosodic structure of the utterances in which they occurred. Findings were that a disproportionate number of errors occurred in initial or ...

This paper is a case study concerning the design and dimensioning of the IP (internet protocol) network of TDC, the largest Danish network operator. Due to historical reasons the number of IP POPs (points of presence) in the network has reached a level, believed to be too high. To point out potential IP POPs for dismantling, we consider a network planning problem concerning dimensioning of the ...
