In this work, we investigate the potential benefits of introducing relay stations in the round-trip ridesharing problem. In the classical round-trip ridesharing system, the pick-up and drop-off locations for the rider don’t differ from his origin and destination, respectively, for both outgoing and return trips. This system is straightforward but inflexible and unbalanced as it puts the whole d...

Communications systems often have many types of users. Since the users share the same resource, there is a conflict in their needs. This conflict leads to the imposition of controls on admission or elsewhere. In this paper, there are two types of customers, GP (Guaranteed Performance) and BE (Best Effort). We consider an admission control of GP customer which has two roles. First, to guarantee ...

Online bandwidth limitations and fluctuations impose a major challenge in estimating the amount of data to transmit in a given time period. Over or under estimation of bandwidth can jeopardize the visual fidelity of the transmitted data and related multimedia data. We propose a Visual Quality Prediction (VQP) model which supports an adaptive fragmented texture transmission approach taking bandw...

When developing and aiming to achieve success in the arena of mobile commerce, user acceptance is a key aspect for consideration. This study aims to empirically examine some of the factors affecting the acceptance of m-commerce within the context of Saudi Arabia. Based on the revised UTAUT model, the revised model include two particular construct : costs and trust to enhance our understanding o...

This paper reports spreadsheet calculations intended to verify the timing of 6-4 GasP asynchronous Network on Chip (NoC) control circuits. The Logical Effort model used in the spreadsheet estimates the delays of each logic gate in the GasP control. The calculations show how these delays vary in response to differing environmental conditions. The important environmental variable is the physical ...

The use of ATMs has become fundamental in the banking industry owing to the values transacted using these systems and their 24/7 usage. Although several researchers have studied the role of biometrics in security applications for financial institutions, no systematic empirical research has been applied to studying the role of organizational characteristics and contextual factors in the Kenyan f...

This paper proposes a novel semi-distributed and practical ICIC scheme based on the Almost Blank SubFrame (ABSF) approach specified by 3GPP. We define two mathematical programming problems for the cases of guaranteed and besteffort traffic, and use game theory to study the properties of the derived ICIC distributed schemes, which are compared in detail against unaffordable centralized schemes. ...

A new software cost estimation approach is proposed in this paper, which attempts to cluster empirical, non-homogenous project data samples via an entropy-based fuzzy k-modes clustering algorithm. The target is to identify groups of projects sharing similar characteristics in terms of cost attributes or descriptors, and utilise this grouping information to provide estimations of the effort need...

This study was undertaken to investigate the relationship between quality of parental homework involvement and academic functioning in the reading domain (reading score, homework effort, and academic procrastination) among students. The statistical population of the study was comprised of all sixth graders in Ardakan, Yazd Province, in school year 2014-15. The sample consisted of 366 students w...
