1 Harrison, Reid R.Analog VLSI implementation of a visual interneuron: enhanced sensory processing through biophysical modelingFlies are capable of rapid, coordinated flight through unstructured environments. This flight is guided by visual motion information that is extracted from photoreceptors in a robust manner. One feature of the fly's visual processing that adds to this robustness is the saturation of wide-fi_x000...1999-01-01
2 Regehr, JohnCPU reservations and time constraints: implementation experience on windows NTThis paper presents an implementation of scheduling abstractions originally developed for the Rialto real-time operating system within a research version of Windows NT called Rialto/NT. These abstractions, CPU Reservations and Time Constraints, as described in the 1997 SOSP paper [Jones et al. 97], ...1999-01-01
3 Harrison, Reid R.Floating gate current mirror for gain correction in CMOS translinear circuitsThe exponential behavior of MOSFETs in subthreshold operation has recently been exploited to build CMOS translinear circuits such as multipliers and log-domain filters. A major obstacle in developing a practical CMOS implementation is the variation in threshold voltage between devices. In transline...1999-01-01
4 Ehleringer, James R.Grupos funcionales en arbustos deserticos del norte de Chile, definidos sobre la base de las fuentes de agua utilizadasLa productividad primaria y la estructura de la vegetación en ecosistemas áridos están determinadas por la disponibilidad de agua. En un estudio realizado en el secano costero del norte-centro de Chile (29/43'S; 71/14'O, 300 m) se compararon los mecanismos de utilización de distintas fuentes de...Grupos funcionales; Functional groups; Arbustos deserticos; Desert shrubs; Fuentes de agua; Water sources; Water availability; Arid ecosystems; Pastoreo con caprinos; Goat overgrazing1999-01-01
5 Regehr, JohnHierarchical schedulers, performance guarantees, and resource managementAn attractive approach to scheduling applications with diverse CPU scheduling requirements is to use different schedulers for different applications. For example: real-time schedulers allow applications to perform computations before deadlines, time-sharing schedulers provide high throughput for com...1999-01-01
6 Olivera, Baldomero M.Multiple bromotryptophan and y-carboxyglutamate residues in a Conus peptideA novel peptide was purified from Conus textile venom which caused hyperactivity in mice. The 31-amino acid peptide has six residues with unusual post-translational modifications: four y-carboxyglutamates and two brominated tryptophan residues. This peptide, which we have designated the dibromorunn...1999-01-01
7 Zhdanov, Michael S.Parameter estimation for 3-D geoelectromagnetic inverse problemsParameter estimation in geoelectromagnetics aims to obtain the most important parameters of a well-defined conductivity model of the Earth. These parameters are features of typical geological structures, such as depth and size of conductive or resistive targets, angle of dike inclination and its le...1999-01-01
8 Regehr, JohnPh.D. Proposal: hierarchical loadable schedulersThe processors in workstations, personal computers, and servers are becoming increasingly powerful, enabling them to run new kinds of applications, and to simultaneously run combinations of applications that were previously infeasible. However, fast hardware is not enough-the operating system must e...1999-01-01
9 Regehr, JohnThe problems you're having may not be the problems you think you're having: results from a latency study of windows NTThis paper is intended to catalyze discussions on two intertwined systems topics. First, it presents early results from a latency study of Windows NT that identifies some specific causes of long thread scheduling latencies, many of which delay the dispatching of runnable threads for tens of millisec...1999-01-01
10 Olivera, Baldomero M.Subfamily Turrinae in the Philippines: the genus Turris (Roding, 1798)Marine gastropods of the family Turridae, commonly known as turrids, comprise the largest living group of venomous snails. The taxonomy of this group, however, has been generally neglected. In this work, the genus Tunis (Roding 1798) is discussed. Out of more than 200 different turrid genera, this g...1999-01-01
11 Zhdanov, Michael S.Three-dimensional quasi-linear electromagnetic modeling and inversionThe quasi-linear (QL) approximation replaces the (unknown) total field in the integral equation of electromagnetic (EM) scattering with a linear transformation of the primary field. This transformation involves the product of the primary field with a reflectivity tensor, which is assumed to vary slo...1999-01-01
