Mobile Crowd Sensing (MCS) is a new paradigm which takes advantage of pervasive smartphones to efficiently collect data, enabling numerous novel applications. To achieve good service quality for a MCS application, incentive mechanisms are necessary to attract more user participation. Most of existing mechanisms apply only for the offline scenario where all users’ information are known a priori....

conclusions the findings of the study showed that, compared with the opiate users, methamphetamine users are younger, more likely to be single, and less likely to have received treatment. we recommend that policymakers should not only design preventive programs for improving the level of knowledge about stimulant use, but also prepare treatment plans and facilities for this newly emerged substa...

one of important issues in designing a supply chain is supplier selection. this issue is complicated, because each supplier should satisfy some criteria from buyer and choosing among them is actually a multi criteria decision making problem. so, there is a need for a structured and systematic approach to solve this problem. in this article, we address supplier selection in an advertising indust...

The explosive growth of wireless applications and high demand for wireless resources have created spectruIIl crisis. Many spectrnm occupancy measurements have shown that most of the allocated spectrum experiences inefficient utilization. Hence radically new approaches arc required for better utilization of spectrum. This has motivated the concept of opportunistic spectrum access in the licensed...

Experiments involving evaluation of new network technologies require realistic network environments. Network traffic is one of the important elements in these environments and many products and approaches are available to generate realistic traffic. However, for efficient evaluation, users should be able to configure their traffic to possess the requisite userdefined characteristics. The existi...

Involving users in the design process is increasingly discussed as the quickest and most reliable way to capture the requirements and needs of users and consumers (Östlund, 2011; Chen & Chan, 2011; Dickinson & Dewsbury, 2006; Habell, 2001; Kohlbacher & Herstatt, 2011). In parallel, the fastest growing segment of the population in Asia and the West is older people (OECD, 2010). A question, howev...

today most of financial analyst believes that companies for creating value should have more return than cost of capital. this concept is operationalised by applying eva an ir. as a result of changes created by stewart in the ri concept, eva has become a new tool of financial performance management. stewart believes that for evaluating internal and external performance eva should be used instead...

The dynamics of belief and knowledge is one of the major components of any autonomous system that should be able to incorporate new pieces of information. In this paper, we argue that to apply rationality result of belief dynamics theory to various practical problems, it should be generalized in two respects: first of all, it should allow a certain part of belief to be declared as immutable; an...

In many fields such as city administration and facilities management, there are increasing requests for a Geographic Information Systein (GIs) that provides automated mapping functions to users. Especially, some mechanism for displaying 3D views of an urban scene is eagerly expected because it allows construction of an intuitive and understandable environment for managing objects in the scene. ...

In this paper, some considerations on the reform of local public transport are presented. In the light of new exigencies, the hope is that the adoption of competitive manoeuvres, although limited, brings about economic advantages and appreciable qualitative improvements of transport services. This should be possible due to new entrants on the market that could favour the implementation of innov...
