Introduction:The overlap syndrome, consisting ofobstructive sleep apnea hypopnea syndrome (OSAHS) and chronic obstructvie pulmonary disease (COPD) is a major problem in COPD patients. OSHAS corresponds to the likelihood of systemic hypertension.The present study was aimed to evaluate the association between apnea-hypopnea index and diastolic blood presssure (DBP) in overlap  patients. Materials...

In the framework of distributed object systems, this paper presents the concepts and an implementation of an overlapping mechanism between communication and computation. This mechanism allows to decrease the execution time of a remote method invocation with parameters of large size. Its implementation and related experiments in the C++// language running on top of Globus and Nexus are described.

In this paper we present a nethod f or computing the synthesis filter (window) needed in a weighted overlap—add (WOLA) scheme for the reconstruction of signals in analysis/synthesis systems used to implement the discrete short time Fourier transform (DSTFT). The method is based on an algebraic representation of the analysis synthesis process and assume that the analysis filter (window) is known...

can be calculated with the FFT and bring the order of arithmetic operations down to Nlog (N) which can be signi cant for large N . This approach, which is called fast convolutions", is a form of block processing since a whole block or segment of x (n) must be available to calculate even one output value, y (n). So, a time delay of one block length is always required. Another problem is the lter...

The Data Distribution Management (DDM) services, one category of HLA management services, control filters for data transmission and reception of data volume among simulators. In this paper, we propose design concept of DDM and show its implementation for RTI. The design concept of DDM is to minimize total amount of message that each federate and a federation process generate using the rate of R...

In this article, a comprehensive study on uncertainty principle of the local polynomial Fourier transform (LPFT) is presented. It shows that the uncertainty product of the LPFT of an arbitrary order is related to the parameters of the signal and the window function, in addition to the errors of estimating the polynomial coefficients. Important factors that affect resolutions of signal represent...

Novel methods of cardiac rhythm detection are proposed that are based on time-frequency analysis by a weighted overlap-add (WOLA) oversampled filterbank. Cardiac signals are obtained from intracardiac electrograms and decomposed into the timefrequency domain and analyzed by parallel peak detectors in selected frequency subbands. The coherence (synchrony) of the subband peaks is analyzed and emp...

PREMISE OF THE STUDY Automatic self-fertilization may influence the geography of speciation, promote reproductive isolation between incipient species, and lead to ecological differentiation. As such, selfing taxa are predicted to co-occur more often with their closest relatives than are outcrossing taxa. Despite suggestions that this pattern may be general, the extent to which mating system inf...

Detecting communities plays a vital role in studying group level patterns of a social network and it can be helpful in developing several recommendation systems such as movie recommendation, book recommendation, friend recommendation and so on. Most of the community detection algorithms can detect disjoint communities only, but in the real time scenario, a node can be a member of more than one ...

We recorded articulatory data to investigate the influence of consonantal coarticulation resistance on consonant-vowel timing in Polish onset clusters. While recent studies found different onset-vowel timing patterns depending on the position of the sibilant within the cluster, it is widely unknown how onset-vowel timing interacts with different degrees of coarticulation resistance of the vowel...
