The problem of destination accessibility is a vital concern in the sustainable tourism development in the emerging regions due to the increasing numbers of tourism business growth in the recent times. Tourism is one of the potential foreign exchange earning sectors, which place sustainability as one of the main success metrics for benchmarking the industry’s overall development. On the other ha...

Reactive routing protocols for mobile ad-hoc networks usually discover routes by disseminating control packets across the entire network; this technique is known as brute-force flooding. This paper presents NARD, which stands for neighbor-assisted route discovery protocol for mobile ad-hoc networks. In NARD, a source node floods a limited portion of the network searching not only for the destin...

the purpose of this study is to develop a brand equity model for isfahan as a tourism destination. the statistical population of this study consists of the inbound tourists who have traveled to isfahan in november 2013. a sample of 200 tourists has been selected from this population. a self-administrated questionnaire has been used for collecting the research data. in order to analyze the resea...

We consider relay channels in which the source-destination and relay-destination signals are assumed to be orthogonal and thus have to be recombined at the destination. Assuming memoryless signals at the destination and relay, we propose a low-complexity quantize-and-forward (QF) relaying scheme, which exploits the knowledge of the SNRs of the source-relay and relay-destination channels. Both i...

The relevance and effectiveness of the World Health Organization's (WHO's) Global Code of Practice on the International Recruitment of Health Personnel is being reviewed in 2015. The Code, which is a set of ethical norms and principles adopted by the World Health Assembly (WHA) in 2010, urges members states to train and retain the health personnel they need, thereby limiting demand for internat...

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,...

We study in this paper the interactions between migration rates and the level of labour standards. We use an augmented version of the Grogger and Hanson (2008) model, adding the level of working conditions into the specification. Our hypothesis is that the differential of working conditions may be a complementary determinant of migration. In a first time, we test the influence of labour standar...

In this paper, we study using Destination Artificial Noise (DAN) besides Source Artificial Noise (SAN) to enhance physical layer secrecy with an outage probability based approach. It is assumed that all nodes in the network (i.e. source, destination and eavesdropper) are equipped with multiple antennas. In addition, the eavesdropper is passive and its channel state and location are unknown at t...

In this chapter, we consider space-time coding strategies for multiple-relay cooperative systems that effectively harness available spatial diversity. More specifically, the goal is to examine ways to efficiently forward signals from multiple relays to the destination while addressing the important practical issue of synchronization among the relays. We assume a general two-phase transmission p...

This paper focuses on a joint relay-selection and resource-allocation algorithm for an Amplify-andForward (AF) cooperative network. In a multiuser scenario, joint relay selection and power allocation is a combinational problem for heterogeneous, i.e., real time (RT) and non-real time (NRT), users. In single relay AF (S-AF) scheme, a source-destination pair selects best relay. Thus only two chan...
