Node cooperation is considered in this paper in the existence of two relaying protocols i.e. “Amplify and Forward (AF)” also called “Store and Forward (SF)” and the second relaying protocol is “Decode and Forward”. The two stated protocols are different from each other and perform different operations on received data before retransmitting to next hop. Also the selection of each protocol is var...

This paper contains three important contributions to the literature on international migrations. First, it compiles a new dataset on migration flows (and stocks) and on immigration laws for 14 OECD destination countries and 74 sending countries for each year over the period 1980-2005. Second, it extends the empirical model of migration choice across multiple destinations, developed by Grogger a...

Migration of health professionals is an important policy issue for both source and destination countries around the world. The majority of migrant care workers in industrialized countries today are women. However, the dimension of mobility of highly skilled females from countries of the global south has been almost entirely neglected for many years. This paper explores the experiences of high-s...

oman has made tremendous progress in the last four decades on the back of rising oil prices and this has led to substantial economic activity in oil, construction, industries and services sectors creating an unprecedented demand for labor ranging from professionals, technical experts, educators, highly skilled people in all vocations to low and semi-skilled people including cleaners, gardeners,...

With few exceptions, the empirical literature on foreign direct investment (FDI) continues to be gender-blind. This paper contributes to filling this gap by assessing the importance of gender inequality in education as a determinant of FDI. We estimate a standard gravity model on bilateral FDI flows which is augmented by educational variables, including different measures of gender inequality i...

Image translation, size scaling and rotation can be analyzed from a unified standpoint. Let for and denote a discrete destination image that is created by geometrical modification of a discrete source image for and . In this derivation, the source and destination images may be different in size. Geometrical image transformations are usually based on a Cartesian coordinate system representation ...

Channel estimation via training is a common method for providing imperfect channel state information (CSI) in a network. In a relay network, imperfect CSI can be efficiently provided at the relays by sending training signals from the source and the destination nodes to the relays. Providing imperfect CSI at the destination is more challenging since each relay is required to send training signal...

Selection or Network Effects? Migration Flows into 27 OECD Countries, 1990-2000 Recent migration patterns show growing migration pressure and changing composition of immigrants in many Western countries. During the latest decade, an increasing proportion of the OECD immigrants have been from poor countries, where the educational level of the population is low. The migration patterns may be affe...
