—Selecting the optimal service from a set of functionally equivalent services is non-trivial. Previous research has addressed this issue making use of Quality of Service (QoS) attributes of the candidate services. In doing this, researchers have however assumed that the customers' preference of the various QoS attributes varies linearly with the actual(More)
—Service composition is an effective practice to perform complex tasks through varied configurations of simple services. An issue that often arises in such a setup is the selection of the best service from a group of functionally equivalent ones to cater to each of the various functionalities of the composite application. Previous effort in this direction(More)
Selecting an optimal service from a group of functionally equivalent ones is non-trivial. This is more so when the service to be selected is part of a composite application. Research in the past has resolved this issue making use of the Quality of Service (QoS) attributes of the services to determine the most optimal from the functionally equivalents. This(More)
— In this paper, we study the problem of determining the optimal number of traffic and control channels in a packet based cellular system. We only consider systems where a given (total) number of available channels are divided into traffic and control channels. We first show how to compute the ratio of required traffic and control channels based on the(More)
—Web service composition is the art of combining multiple platform independent and modular pieces of software with varied configurations, to achieve an efficient solution for a complex business process. Though Web service composition has been an important area of research in the past decade, the search for procuring an optimal configuration of Web services(More)
Users interact with many electronic devices via menus such as auditory or visual menus. Auditory menus can either complement or replace visual menus. We investigated how advanced auditory cues enhance auditory menus on a smartphone, with tapping, wheeling, and flicking input gestures. The study evaluated a spindex (speech index), in which audio cues inform(More)
—The widespread adoption of service oriented architecture owes its popularity to service composition, where several web services are combined dynamically at runtime. As is evident today, the Internet is evolving towards the 'Future Internet'. In this context, web service composition has to deal with the problems of mobility, fault tolerance, reliability and(More)
In part I of this work, we study adhesionless contact of a long rectangular elastic membrane with a rigid substrate. Our model is based on finite strain theory and is valid for arbitrarily large deformations. Both frictionless and no-slip contact conditions are considered. Exact closed form solutions are obtained for frictionless contact. For small contact,(More)
