(Elsevier, 2022-08-28)
Article
Accés obertPolycrystalline cubic boron nitrides (PcBNs) are composites widely used as cutting tool materials due to their exceptional high hardness and wear resistance. Investigation of their micromechanical properties is key for ... -
N-gram-based Machine Translation
(2006-12)
Article
Accés obertThis article describes in detail an n-gram approach to statistical machine translation. This approach consists of a log-linear combination of a translation model based on n-grams of bilingual units, which are referred to ... -

On the inverse windowed Fourier transform
(IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 1999-11-30)
Article
Accés obertThe inversion problem concerning the windowed Fourier transform is considered. It is shown that, out of the infinite solutions that the problem admits, the windowed Fourier transform is the "optimal" solution according to ... -
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 ... -
