The market interest in developing reliable and stable products at shorter development time and reduced cost, has led to an increasing surge of interest in Component-Based Software Engineering. The success of these systems largely depends on the effective selection of components that meet users requirements. In this context, the products evaluation needs to be a simultaneous process with the req...

Cardiac monitoring is an important application of mobilemonitoring systems. Such systems typically require experts to label electrocardiogram (ECG) data; however, large interand intra-expert variation limits the reliability and accuracy of diagnosis. This paper presents a process of integrating the mobile end of the system with a back-end annotation system for reviewing and scoring the quality ...

We report on some recent work of the authors showing the relations between singular (point) perturbation of the Laplacian and the dynamical system describing a charged point particle interacting with the self–generated radiation field (the Maxwell–Lorentz system) in the dipole approximation. We show that in the limit of a point particle, the dynamics of the system is described by an abstract wa...

287 Numerous organizations are involved in distributing goods and materials. When shipping alternatives exist, the selection of the appropriate shipping alternative (mode) for each shipment may result in significant cost savings. This paper describes a highly flexible dispatching system that selects the shipping mode to be used for each shipment while minimizing the overall shipping costs. Mult...

Comparative work on human spatial cognition contrasts systems of calculating position and trajectory that involve body-relative reckoning frequently where the body in question is that of an egocentric observer with systems which rely on global coordinates such as compass directions not relative to the positions and orientations of moveable entities. I consider here a case from a Tzotzil speaker...

The rapid development in the technologies for Wireless Sensor Networks (WSN) have generated a huge interest among embedded developers as it gives freedom from wires, easy development, reduced cost of hardware, reduced maintenance and very useful in unattended situations. WSN provides low cost solutions to variety of real-world problems. Sensors are low cost tiny devices with limited storage, co...

A double sampled second order ΣΔ modulator with an analog look ahead (ALA) approach is presented. The proposed architecture provides an extra clock period to be used for the quantization. The feedforward path in both integrators allows the further reduction of the output voltage swing, relaxing also the slew-rate requirements of the op-amps. Moreover, the modulator enables the reduction of the ...

From the mid-1980s until 1994, U.S. oil and gas exploration and production steadily declined, forcing a significant increase in U.S. imports of crude oil. For example, in 1994, the United States imported more than 50 percent of the nation's total demand, which was the highest level since 1990. To economically develop U.S. oil production in deep-water locations, the industry needed strong, light...

Against the backdrop of new economic realities, one of the larger forces that is affecting businesses worldwide is cloud computing, whose benefits include agility, time to market, time to capability, reduced cost, etc. The intent of this research was to contribute to the body of knowledge that could be applied by researchers, businesses, and IT organizations alike to achieve optimal results thr...
