Introduction: Rheumatoid Arthritis (RA) can get a considerable impact on patients’ quality of life. Path analysis is an exact statistical method for determining the best causative model of variables. So, the aim of this paper is application of regression based path analysis for introduction of the best model of RA quality of life determinants, using Precede Model constructs. Methods: Thi...
We propose a new active nonlinear model of the frequency response of the basilar membrane in biological cochlea called the simple dual path nonlinear (SDPN) model and a novel sound processing strategy for cochlear implants (CIs) based upon this model. The SDPN model was developed to utilize the advantages of the level-dependent frequency response characteristics of the basilar membrane for robu...
In modern supply chain management systems, Radio Frequency IDentification (RFID) technology has become an indispensable sensor technology and massive RFID data sets are expected to become commonplace. More and more space and time are needed to store and process such huge amounts of RFID data, and there is an increasing realization that the existing approaches cannot satisfy the requirements of ...
Lightning discharges radiate the bulk of their electromagnetic energy in the very low frequency (VLF, 3–30 kHz) and extremely low frequency (ELF, 3–3000 Hz) bands. This energy, contained in impulse-like signals called radio atmospherics or sferics, is guided for long distances by multiple reflections from the ground and lower ionosphere. This suggests that observed sferic waveforms radiated fro...
This paper provides a framework for error rate performance analysis of maximal ratio combining multichannel reception of coherent -ary phase-shift keying (MPSK) systems over slowly fading channels. Each channel is described by a two-sided discrete model with correlated complex Gaussian taps based on bandlimiting an underlying WSSUS physical channel. The resulting “resolved channel” performance ...
Latent class analysis (LCA) is a method of evaluating non sampling errors, especially measurement error in categorical data. Biemer (2011) introduced four latent class modeling approaches: probability model parameterization, log linear model, modified path model, and graphical model using path diagrams. These models are interchangeable. Latent class probability models express l...
The present research was performed to Design the Marital Adjustment Model with due attention to Islamic life Style and Perfectionism in High School Teachers in Birjand. The method of research was non experimental and structural equation Modeling (SEM). A sample of 300 teachers from Birjand city was selected through random cluster sampling (150 male and 150 female). The tools included: Locke-Wal...
In this paper, to model the path-loss characteristics in urban line-ofsight(LOS) propagation, we performed measurements in Goyang, Republic of Korea, at a frequency of 2.4GHz using the IEEE 802.15.4 standard. Although path-loss variance for any street existed, measurements yielded a typical pathloss of PL(dB) = L r ) ( log 10 10 , where is the path-loss coefficient, r is the street le...
We consider finite graphs whose edges are labeled with elements, called colors, taken from a fixed finite alphabet. We study the problem of determining whether there is an infinite path where either (i) all colors occur with the same asymptotic frequency, or (ii) there is a constant which bounds the difference between the occurrences of any two colors for all prefixes of the path. These two not...
