High-resolution rainfall data sequences serve as inputs for a range of applications in planning, design and management of small (mostly urban) water resources systems. These applications include continuous flow simulation, rain water tank design, and the evaluation of alternate policies for assessment of environmental impacts. However, high-resolution rainfall data are often not available, sinc...

Vesicoureteral reflux (VUR) is the most common underlying etiology responsible for febrile urinary tract infections (UTIs) or pyelonephritis in children. Along with the morbidity of pyelonephritis, long-term sequelae of recurrent renal infections include renal scarring, proteinuria, and hypertension. Treatment is directed toward the prevention of recurrent infection through use of continuous an...

We show that illumination by continuous white radiation saturates the population of levels so that some of the transitions are not observed. This reduces the number of observable transitions so that the resolution of neighboring transitions is improved. In the case of ν = 11/2 the improved resolution leads to clear observation of zero in the ρxx which appears as a finite resistivity minimum in ...

Hybrid observer design is addressed for a class of discrete-time linear switched systems whose switching mechanism is unknown. The hybrid observation problem consists in determining the estimation of the current mode and the continuous observer for continuous behavior from a finite set of input-output data. First, the current mode is estimated using a classification algorithm that associates th...

Integration of analog-to-digital signal conversion circuits into digital submicron silicon chips is required for many applications. This is typically implemented by sigma–delta circuits, which can provide good resolution without requiring trimming of component values. This paper presents an analytical comparison of noise performance in four alternative sigma–delta circuit configurations which h...

Inherent characteristics of mobile devices make resource discovery in mobile grid challenging. Adding to the complexity is heterogeneity and hence multi-attribute management of these devices. Decentralized resource discovery using DHTs incur maintenance overheads when changes in attributes are continuous and rapid. The paper proposes a novel dual heap non-DHT overlay (DEEPG) for query resolutio...

Continuous wave operation of quantum cascade lasers is reported up to a temperature of 312 kelvin. The devices were fabricated as buried heterostructure lasers with high-reflection coatings on both laser facets, resulting in continuous wave operation with optical output power ranging from 17 milliwatts at 292 kelvin to 3 milliwatts at 312 kelvin, at an emission wavelength of 9.1 micrometers. Th...

Conflict resolution has always been a sensitive matter in air-traffic management. Current European projects aim partial or total automation of air traffic control to deal with the constant growth of air traffic. Technological advances on flight management system allows us to consider an automatic conflict resolution using continuous trajectories. In this paper, we present a new methodology that...

Although most current diffuse optical brain imaging systems use only nearest- neighbor measurement geometry, the spatial resolution and quantitative accuracy of the imaging can be improved through the collection of overlapping sets of measurements. A continuous-wave diffuse optical imaging system that combines frequency encoding with time-division multiplexing to facilitate overlapping measurem...
