This is the first of a series of papers extending a 1+3 covariant and and gauge invariant treatment of kinetic theory in curved space-times to a treatment of Cosmic Background Radiation (CBR) temperature anisotropies arising from inhomogeneities in the early universe. This paper deals with algebraic issues, both generically and in the context of models linearised about Robertson-Walker geometri...

Signal processing using orthogonal cutting force components for tool condition monitoring has established itself in literature. In the application of single axis strain sen­ sors however a linear combination of cutting force compo­ nents has to be processed in order to monitor tool wear. This situation may arise when a single axis piezoelectric actuator is simultaneously used as an actuator and...

Finding structure in multiple streams of datais an important problem. Consider thestreams of data flowing from a robot’s sen-sors, the monitors in an intensive care unit,or periodic measurements of various indica-tors of the health of the economy. Thereis clearly utility in determining how currentand past values in those streams are relatedto future values. W...

INTRODUCTION Inertial Sensors Systems (ISS) are a new generation of low cost, portable, fully wearable motion analysis systems recently become available on the market [1]. ISS sensing units (SU) are lightweight boxes integrating accelerometers, gyroscopes and magnetometers. For each SU a local system of reference (SoR) is defined, and its relative orientation with respect to a global, earth-bas...

This pa per re ports on a new par al lel im ple men ta tion of the pri mal sim plex method for mini mum cost net work flow prob lems, that de com poses both the piv ot ing and pric ing op era tions. The selfscheduling ap proach is both flexi ble and ef fi cient; its im ple men ta tion is close in speed to the best se rial code when us ing one proc es sor, and is ca pa ble of sub stan tial speed...

We present an approach for camera calibration from the image of at least two circles arranged in a coaxial way. Such a geometric configuration arises in static scenes of objects with rotational symmetry or in scenes including generic objects undergoing rotational motion around a fixed axis. The approach is based on the automatic localization of a surface of revolution (SOR) in the image, and it...

In this paper, performance of multistage interconnection network with wormhole routing and packet switching has been evaluated for cache-coherent shared-memory multiproces-sors. The evaluation is based on execution-driven simulation using various applications. The traac in cache-coherent systems is very diierent from the traac in message-passing environment and is characterized by traac bursts,...
