Routing with prioritization based on statistics in OBS networks
(2009)
Text en actes de congrés
Accés obertThis paper introduces a new strategy to provide QoS in IP/OBS networks, using Routing with Prioritization Based on Statistics (RPBS). This proposal uses the feedback scheme in optical networks to provide statistical knowledge ... -
Scarcity of crossing dependencies: A direct outcome of a specific constraint?
(American Chemical Society (ACS), 2017-12-04)
Article
Accés obertThe structure of a sentence can be represented as a network where vertices are words and edges indicate syntactic dependencies. Interestingly, crossing syntactic dependencies have been observed to be infrequent in human ... -
Spatial distribution analysis with capture effect of a mobile S-ALOHA network
(Institute of Electrical and Electronics Engineers (IEEE), 1998)
Text en actes de congrés
Accés obertThe throughput performance of a mobile S-ALOHA network can be improved considering the capture phenomenon, which also depends on the spatial distribution of the mobiles within the cell. We have studied the capture probabilities ... -
Statistical analysis and comparison of 2T and 3T1D e-DRAM minimum energy operation
(Institute of Electrical and Electronics Engineers (IEEE), 2016)
Text en actes de congrés
Accés obertBio-medical wearable devices restricted to their small-capacity embedded-battery require energy-efficiency of the highest order. However, minimum-energy point (MEP) at sub-threshold voltages is unattainable with SRAM memory, ... -

Statistical analysis of stoppages in a metal stamping line: a case study
(OmniaScience, 2023-11)
Article
Accés obertPurpose: This article seeks to establish a statistical analysis to estimate the time of stoppages in a stamping line, which have a high variability that generates an unreliable scenario for the production program. Likewise, ... -
Statistical Modelling of Channel Occupancy in Trunked PAMR Systems
(Elsevier Science B.V., 1997-06)
Article
Accés restringit per política de l'editorialPublic access mobile radio systems (PAMR) using trunking technology allow more efficient use of the frequency spectrum, as all the users of the system jointly use a common pool of channels. Trunked PAMR systems can operate ... -
Statistical reference criteria for adaptive signal processing in digital communications
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 1997-01-01)
Article
Accés obertA general criterion for the design of adaptive systems in digital communications called the statistical reference criterion is proposed. The criterion is based on imposition of the probability density function of the ... -
Statistical study of resonance in AC traction systems equipped with Steinmetz circuit
(2013-10)
Article
Accés restringit per política de l'editorialAC traction systems can be 25 kV/50 Hz single-phase, non-linear, time-varying loads of random naturecausing unbalance and distortion of the supply voltages. To reduce voltage unbalance, thyristor controlledreactances are ... -
Statistics of the slope-method estimator
(Optical Society of America, 2000-11-30)
Article
Accés obertThe slope method has customarily been used and is still used for inversion of atmospheric optical parameters, extinction, and backscatter in homogeneous atmospheres from lidar returns. Our aim is to study the underlying ... -
Strict calculation of the light statistics at the output of a travelling wave optical amplifier
(Institution of Electrical Engineers, 1993-08)
Article
Accés obertA new method for calculating the probability density function of the photon number propagating through a travelling wave optical amplifier with no restriction on its working regime (linear and nonlinear) is reported. The ... -

Accés obertStructural Health Monitoring is a growing area of interest given the benefits obtained from its use. This area includes different tasks in the damage identification process, among them, the most important is the damage ... -
System identification using a linear combination of cumulant slices
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 1993-07-01)
Article
Accés obertIn this paper we develop a new linear approach to identify the parameters of a moving average (MA) model from the statistics of the output. First, we show that, under some constraints, the impulse response of the system ... -
The continuous wavelet transform as a maximum entropy solution of the corresponding inverse problem
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 1999-07-31)
Article
Accés obertThe continuous wavelet transform is obtained as a maximum entropy solution of the corresponding inverse problem. It is well known that although a signal can be reconstructed from its wavelet transform, the expansion is ... -
