Background: Since in multiple sclerosis (MS), changes in speech and voice quality often precede other signs and symptoms; early diagnosis of these changes is necessary. In this study, an acoustic examination of phonation subsystem was performed. Due to the progressive nature of multiple sclerosis, the aim of this study was to examine the correlation between acoustic parameters ...

BACKGROUND The presence of multiple chronic conditions is associated with lower health related quality of life (HRQOL). Disease severity also influences HRQOL. To analyse the effects of all possible combinations of single diseases along with their severity on HRQOL seems cumbersome. Grouping diseases and their severity in specific organ domains may facilitate the study of the complex relationsh...

Abstract | In this paper, a multi-carrier spreadspectrum (MC-SS) code division multiple access (CDMA) system with RAKE receiver is investigated in a multi-user environment. The impact of the non-ideal MC-SS code signal autoand crosscorrelation properties on the system performance is examined. Terms for the probability of bit errors are derived considering these correlation behaviors. Furthermor...

Modern drug discovery for Central Nervous System pathologies has recently focused its attention to in vitro neuronal networks as models for the study of neuronal activities. Micro Electrode Arrays (MEAs), a widely recognized tool for pharmacological investigations, enable the simultaneous study of the spiking activity of discrete regions of a neuronal culture, providing an insight into the dyna...

Copulas are a general tool for assessing the dependence structure of random variables. Important properties as well as a number of examples are discussed, including Archimedean copulas and the Marshall-Olkin copula. As measures of the dependence we consider linear correlation, rank correlation, the coefficients of tail dependence and association. Copulas are a tool for modeling and capturing th...

In this paper we consider the design of practical interleavers for interleaver division multiple access (IDMA) systems. A set of interleavers is considered to be practical if it satisfies two criteria one it is easy to generate (i.e., the transmitter and receiver need not store or communicate many bits in order to agree upon an interleaver), and second no two interleavers in the set “collide”. ...
