To evaluate the expected availability of a backbone network service, administrator should consider all possible failure scenarios under specific service model stipulated in corresponding service-level agreement. Given increase natural disasters and malicious attacks with geographically extensive impact, considering only independent single component failures is often insufficient. This paper bui...

We minimally extend the Standard Model field content by adding new vector-like fermions at TeV scale to allow gauge coupling unification a realistic scale. embed model into $SU(5)$ grand unified theory that is asymptotically safe and features an interacting fixed point for coupling. There are no Landau poles of $U(1)$ Higgs couplings. Gauge, Yukawa couplings retraced from matched those rescaled...

The unified hybrid censoring is a mixture of generalized Type-I and Type-II hybrid censoring schemes. This article presents the statistical inferences on Generalized Exponential Distribution parameters when the data are obtained from the unified hybrid censoring scheme. It is observed that the maximum likelihood estimators can not be derived in closed form. The EM algorithm for computing the ma...

In contrast to the classical findings of lightness constancy, recent psychophysical studies show the strong dependency of the perceived reflectance of a surface on the structure of the natural illumination. The present study examined this inconstancy for systematic variations in the light field and an image-based explanation for it. Observers matched the specular and diffuse reflectance of a th...

Abstract The salinity structure in estuaries is classically described terms of the as well mixed, partially or salt wedge. existing knowledge about processes that result such structures comes from highly idealized models are restricted to either well-mixed and mixed cases subtidal wedge estuaries. Hence, there still little driving transitions between these different estuarine parameters at whic...

This study attempts to reveal the effect of family structure on social participation of  Payame Noor university students, it consists of 339 students. The theoretical framework of this investigation is based on two hypotheses. Hegen personality structure theory and Parsons action theory.  One hypotheses is on satisfactoriness in the family structure were based on personality structure theory an...

this paper presents a new design for a microstrip dual-band band-pass microstrip filter (bpf) with suitable isolation between two passbands. in this design, a basic structure is used to achieve a desirable frequency characteristic in the passband. in this regard, defected ground structure (dgs) is implemented to reach optimum parameters of the filter such as bandwidth, return loss, insertion lo...

Due to its attractive properties, generalized frequency division multiplexing (GFDM) is recently being discussed as a candidate waveform for the fifth generation of wireless communication systems (5G). GFDM is introduced as a generalized form of the widely used orthogonal frequency division multiplexing (OFDM) modulation scheme and since it uses only one cyclic prefix (CP) for a group of symbol...
