Does central bank transparency affect stock market volatility?
(2014)This paper addresses the issue of impacts of central banks' transparency on stock market volatility. Using a simple theoretical macroeconomic model, we analytically find a negative link between stock prices volatility and ... -
The Impact of Parental Bonding on Sexual Distress in Women with Type 1 Diabetes Mellitus
(2013)Introduction. Psychosomatic and social issues have been found to be determinants of sexual distress in diabetic and non-diabetic populations. However, the role of parental bonding as a determinant for sexual distress has ... -
Inverse Gaussian Modeling of Turbulence-Induced Fading in Free-Space Optical Systems
(2011)We propose the inverse Gaussian distribution, as a less complex alternative to the classical log-normal model, to describe turbulence-induced fading in free-space optical (FSO) systems operating in weak turbulence conditions ... -
Node Isolation Probability for Serial Ultraviolet UV-C Multi-hop Networks
(2011)Non-line-of-sight optical wireless transmission, operated in the unlicensed ultraviolet UV-C band, has been recently suggested as an alternative means of communication. However, due to limited coverage, relayed UV-C networks ... -
Optical Wireless Links with Spatial Diversity over Strong Atmospheric Turbulence Channels
(2009)Optical wireless, also known as free-space optics, has received much attention in recent years as a cost-effective, license-free and wide-bandwidth access technique for high data rates applications. The performance of ... -
Parallel short range molecular dynamics simulations on computer clusters: Performance evaluation and modeling
(2005)This paper describes the performance of a portable molecular dynamics code running on an eight-node PC cluster. The molecular dynamics code is based on the atom decomposition method for distributing the computation load ... -
Performance Analysis of a Laser Ground-Station-to-Satellite Link With Modulated Gamma-Distributed Irradiance Fluctuations
(2010)The performance of a ground-station-to-space laser uplink with a Gaussian-beam wave model subject to turbulence and beam wander effects is the topic of the present study. The modulated gamma distribution is used to describe ... -
Performance of a laser Earth-to-satellite link over turbulence and beam wander using the modulated gamma-gamma irradiance distribution
(2011)We present an analytical framework for the performance evaluation of laser satellite uplinks over the major probabilistic impairments, i.e., atmospheric turbulence and beam wander. Specifically, we consider a ground-stat ... -
Underwater Optical Wireless Networks: A k-Connectivity Analysis
(2014)In this paper, optical wireless has been addressed as a promising technology to provide high-bandwidth services for underwater communications. However, the significant attenuation degree due to high absorption and scattering ...
