Using game elements to increase students’ motivation for providing peer assistance

2017

Master's thesis Multimedia and Educational Technology MM500 - University of Agder 2017 Abstract Peer assistance is a support system where people of equal status help each other solve problems. It is also a recognized method within education where students support each other with their assignments. The positive effect of peer assistance is well known, and it would be favorable if more students participated and took on the role as peer-teachers. To increase the activity of peer assistance, several incentives can be used, including game elements. In “Using game elements to increase peer assistance among university students”, (Nordengen & Brinch, 2016, p. 1) tried to predict which game elements…

Theoretical Game Approach for Mobile Users Resource Management in a Vehicular Fog Computing Environment

2018

Vehicular Cloud Computing (VCC) is envisioned as a promising approach to increase computation capabilities of vehicle devices for emerging resource-hungry mobile applications. In this paper, we introduce the new concept of Vehicular Fog Computing (VFC). The Fog Computing (FC) paradigm evolved and is employed to enhance the quality of cloud computing services by extending it to the edge of the network using one or more collaborative end-user clients or near-user edge devices. The VFC is similar to the VCC concept but uses vehicles resources located at the edge of the network in order to serve only local on-demand mobile applications. The aim of this paper is to resolve the problem of admissi…

Service Provisioning and User Association for Heterogeneous Wireless Railway Networks

2017

In addition to comforting passengers' journey, the modern railway system is responsible to support a variety of on-board Internet services to meet the passenger's demands on seamless service provisioning. In order to provide wireless access to the train, one idea attracting increasing attention is to deploy a series of track-side access points (TAPs) with high-speed data rates along the rail lines dedicated to the broadband mobile service provisioning on board. Due to the heavy data traffic flushing into the base stations (BSs) of the cellular networks, TAPs act as a complement to the BSs in data delivery. In this paper, we focus on the TAP association problem for service provisioning in a …

Service Provisioning with Multiple Service Providers in 5G Ultra-dense Small Cell Networks

2015

In this work, a game theoretical approach for addressing the virtual network service providers (NSPs), small cell provider (SCP) and user interaction in heterogenous small cell networks is presented. In particular, we consider the users can select the services of different NSPs based on their prices. The NSPs have no dedicated hardware and need to rent from the SCP in term of radio resources, e.g., small cell base stations (SBSs) in order to provide satisfied services to the users. Due to the fact that the selfish parties involved aim at maximizing their own profits, a hierarchical dynamic game framework is presented to address interactive decision problem. In the lower-level, a Stackelberg…

Les populations périurbaines face à l'automobile en grande couronne francilienne

2007

The present article is attempting to identify if the automobile, which took part in development of periurban spaces but which causes strong disparities of mobility between households, according to their incomes and of their age, leads to exclude an increasing part of the population in this spaces. We looked more closely into not-motorized population but also motorized households, of modest income or older age, for which cost or physical requirements of automobile mobility are too high. Our results show that number of not-motorized households, most strongly marginalized, decrease in particular in periurban territories most dependent on car, in spite high level of unemployment and ageing of p…

Latency-Oblivious Distributed Task Scheduling for Mobile Edge Computing

2018

Mobile Edge Computing (MEC) is emerging as one of the effective platforms for offloading the resource- and latency-constrained computational services of modern mobile applications. For latency- and resource-constrained mobile devices, the important issues include: 1) minimize end-to-end service latency; 2) minimize service completion time; 3) high quality-of-service (QoS) requirement to offload the complex computational services. To address the above issues, a latencyoblivious distributed task scheduling scheme is designed in this work to maximize the QoS performance and goodput for the MEC services. Unlike most of the existing works, we consider the latency-oblivious property of different …

Mining Customer Requirement from Helpful Online Reviews

2014

Today there are a huge quantity of online reviews available across different categories of products. The key question is how to select helpful online reviews and what can we learn from the abundant reviews. In this paper, we first conclude five categories of features to predict reviews' helpfulness from the perspective of a product designer and then present an approach based on conjoint analysis to measure customer requirement. The suggested approach are demonstrated using product data from a popular Chinese mobile phone market.

Introducing usability heuristics for mobile map applications

2013

In this paper, a set of heuristics for evaluating the usability of mobile map applications is introduced. We developed the heuristics by exploring the present generic heuristics and then forming new theory-based heuristics. Usability specialists tested the heuristics by evaluating the usability of a mobile map application with both generic and domain-specific heuristics. As a result, more usability problems were found with the proposed domain-specific heuristics. In addition, based on the evaluators’ views the initial domain-specific heuristics were further developed. We conclude by proposing domain-specific usability heuristics for evaluating the mobile map applications. peerReviewed

Perceived Well-being Effects During the Implementation of a Self-tracking Technology

2016

In recent years, both individuals and the healthcare sector have become more interested to measure and improve health and well-being by using different selftracking technologies. However, the number of studies concerning the experiences that people have with these technologies is still rather limited. This study investigates the expectations and perceived short-term effects of using self-tracking technologies on users’ well-being. The focus is on the first weeks of usage i.e., the implementation phase. The study is qualitative in nature and based on thematic analysis of ten semistructured interviews. The results reveal that the perceived well-being effects of using a self-tracking technolog…
