We describe a highly portable head-mounted display designed for use in action sports such as skiing and snowboarding. The low field-of-view, monocular display is designed to keep distraction to a minimum and not impede the mobility of the wearer. Implications of the location of the monocular display are discussed. The driving electronics and power source are small enough so that no tethering is ne... View full abstract»

Mobility models play an influential role in the simulation studies of mobile ad hoc networks (MANETs). Realism and simplicity are two attractive properties of mobility models, and achieving both together in modeling mobility has been a challenging task. Recently, a framework of moblity models called destination guided mobility (DGM) models for MANETs was proposed. This framework can be used to dev... View full abstract»

Traditional E-Commerce applications have evolved in the last years due to the growth of the mobile environment, creating a new research area known as U-Commerce. The application of these techniques in the banking environment has been a direct outcome in order to enhance the services offered to end users. In this paper, we present a context-aware mobile recommender system based on real banking data... View full abstract»

Proxies can be used as gateways between remote resources and mobile devices to deal with the challenges resulted from disconnections and the limited resources of mobile devices. This paper describes a proxy-based infrastructure that provides proxy services to support mobile device applications. Proxy services can be thought of as a library of functions where the functions execute on a proxy and se... View full abstract»

In this paper, we describe a mobile application that synchronizes the playback of a video stream among a group of mobile devices while the video playback is controlled (e.g. pause, resume, seek) by one of the devices. This feature allows a group of people to collaborate remotely in real-time through watching the same video on their mobile devices. To make this application work for heterogeneous mo...

Participatory sensing (PS) systems are a new emerging sensing paradigm based on the participation of cellular users. While they present interesting characteristics, such as spatiotemporal granularity and low cost, they also create new problems and challenges. One key challenge in PS systems is that of the determination of the locations and number of users where to obtain samples from so that we ca... View full abstract»

Music Information Retrieval (MIR) is a crucial topic in the domain of information retrieval. According to major characteristics of music, Query-by-Humming system retrieves interesting music by finding melody that contains similar or equal melody to the humming query. Basing on the designed fuzzy inference model a novel Query-by-Humming/Singing system is proposed to extract pitch contour informatio... View full abstract»

In this paper, we propose a location-based large-scale landmark image recognition scheme for mobile devices such as smart phones. To achieve this goal, we collected landmark images all around the world, which were available on the web. For each landmark, we detected interest points and constructed their feature descriptors using SURF. Next, we performed a statistical analysis on the local features... View full abstract»

The Semantic Web aims to enrich the existing Web by building an infrastructure layer of a web of data. Three-quarters of the data on the Web come from relational databases. Thus, in the context of the Semantic Web, it has become one of the most important topics to generate OWL ontologies from the legacy databases. For this purpose, the existing approaches typically define how to map the databases ... View full abstract»

Online social networks (OSNs) have become the most popular services on the Internet, and such systems have become part of users' life all over the world. They visit such systems every day and spend more and more time on them. So understanding users' behavior is important to understand such systems. This paper presents results from our measurement on the large-scale OSN spanned by Weibo, the most p... View full abstract»

Offset assignment (OA) is a highly effective address code optimization technique for embedded processors with limited memory. Modify registers (MRs) concern the offset difference of address code for offset assignment (OA) problems. Address registers (ARs) concern the assignment of program variables for general offset assignment (GOA) problems. This paper proposes a novel MRs and ARs assignment tec... View full abstract»

Traditional e-voting systems replace the paper-based process with an electronic one at official voting locations. Remote e-voting, where the voter can vote from any location, increases both participation rates in the elections and the user's satisfaction as it eases the voting process and saves time. However, having a remote e-voting system increases the security vulnerabilities. Those vulnerabili... View full abstract»
