Medical ultrasound (US) images are characterized by inherent noise perturbations which introduce uncertainty in their interpretation even by experienced radiologists. In this paper we propose a novel deformable model for medical US image segmentation, which incorporates a combination of domain and boundary integrals for the alleviation of the noise effects. It can be applied as a diagnostic aid...

In this paper methods for analysing and processing digitised compressed video newsfeeds are discussed. Due to computing, storage and communication limitations the material has to be processed in compressed form. This creates particular problems which are not encountered when decompressed video material is handled. The methods described allow news editors to directly extract information from the...

{ This paper presents a sensor based docking strategy for a non holonomic mobile platform used to support material transportation operations in industrial like environments. A low cost in-frared sensor system was designed and implemented, aiming at locating the mobile platform relative to the docking station where passive reeectors are installed. With this information, trajectories are generate...

The numerous early drawings made by the enigmatic Abstract Expressionist, Clyfford Still, have remained largely undiscovered due to the strict requirements of the artist’s will. Still demonstrated a fast-paced development of a unique aesthetic leading to abstraction as a young man; however, the earliest known drawings, circa 1920, are stylistically consist with a group of drawings performed ove...

n-player coalitional games with transferable payo® o®er a promising framework for analyzing value appropriation under competition. But making progress necessitates understanding how the force of a player's value-producing alternatives a®ects the upper and lower bounds of his set of equilibrium (core) payo®s. Unfortunately, there are virtually no results of this kind. We explore the determinants...

We present the solution that Hypo Real Estate Bank International (Hypo) implemented to perform Monte Carlo simulations of its commercial real estate credit risk. The solution uses Risk Integrated’s proprietary software, the Specialized Finance System, which is supported by another Risk Integrated technology, the Enterprise Spreadsheet Platform. The platform embeds individual master spreadsheets...

The paper proposes a solution for the Grid scheduling problem, addressing in particular the requirement of high performance an efficient algorithm must fulfill. Advance Reservation engages a distributed, dynamic, fault-tolerant and efficient strategy which reserves resources for future task execution. The paper presents the main features of the strategy, the functioning mechanism the strategy i...

Discrimination as a Competitive Device: The Case of Local Television News Local news offers a unique look not only at customer preferences but also at the strategic response of firms to these preferences. This paper uses a combination of ratings data and newly gathered information on television stations in 25 U.S. markets to examine the decisions of competing firms and how customers respond to ...

HE retirement is a concept of recent origin though it could be traced to Indian philosophy. The reasons related to voluntary retirement scheme (VRS) of Government of India and its response by public sector employees have been analyzed in this paper. There are number of reasons for opting to VRS like doing some business, job dissatisfaction, health and personal reasons. There exists variation in...

In this paper, we consider the problem of resource reservation for networks. Current approaches for resource reservation in Integrated Service Networks adopt an all-or-nothing approach, where partially acquired resources must be released if resources are not available at all routers on the chosen path. Furthermore, under high load, endsystems must retry requests repeatedly leading to inefficien...
