Optimum energy allocation for massive spread-spectrum multiple access in networks of uncoordinated energy-limited terminals
(Institute of Electrical and Electronics Engineers (IEEE), 2016)
Text en actes de congrés
Accés obertThis paper derives the energy allocation policy that maximizes the aggregate spectral efficiency of an uncoordinated spread-spectrum multiple access network operating in the large-user regime and subject to a longterm ... -
PCA based stress monitoring of cylindrical specimens using PZTs and guidedwaves
(Multidisciplinary Digital Publishing Institute (MDPI), 2017-12)
Article
Accés obertSince mechanical stress in structures affects issues such as strength, expected operational life and dimensional stability, a continuous stress monitoring scheme is necessary for a complete integrity assessment. Consequently, ... -
Performance analysis of a new packet trace compressor based on TCP flow clustering
(Institute of Electrical and Electronics Engineers (IEEE), 2005)
Text en actes de congrés
Accés obertIn this paper we study the properties of a new packet trace compression method based on clustering of TCP flows. With our proposed method, the compression ratio that we achieve is around 3%, reducing the file size, for ... -
Performance analysis of an ISMA DS-CDMA packet data network
(Institute of Electrical and Electronics Engineers (IEEE), 1999)
Text en actes de congrés
Accés obertThe efficiency of MAC protocols for a packet switching DS-CDMA network strongly depends on the offered traffic statistic. For bursty sources where transmission needs are restricted to short message lengths, a protocol such ... -
Pitch determination of noisy speech using higher order statistics
(. IEEE, 1992)
Text en actes de congrés
Accés obertThe use of third-order statistics to determine the pitch of a speech signal and how they can eliminate the effect of a wide range of noises, including those generated by periodic sources, are shown. The proposed algorithm ... -
Positive time-frequency distributions based on joint marginal constraints
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 1996-08-01)
Article
Accés obertThis correspondence studies the formulation of members of the Cohen-Posch class of positive time-frequency energy distributions. Minimization of cross-entropy measures with respect to different priors and the case of ... -

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
