Nowadays, with the cloud's charismatic storage and computation power, more and more traditional services (social networking service, location-based services, etc.) are being migrated onto cloud platforms. These cloud services on different cloud platforms could be employed to form cross-cloud mobile applications of mobile cyber-physical systems (CPS). However, a cloud service may have various versions...
This article focuses on the issue of the use of mobile technologies, especially on online Laboratories, as a support to professional development of adults in the work situation in Senegal. More specifically, how mobile learning can be a solution to access to education for nomadic professionals working specifically in the area of computer networks? This issue is at the heart of a doctoral research...
The keen adoption of m-learning by higher education institutions on a global scale because of widespread use of mobile devices requires proper security considerations in order not to expose m-learning systems to cyber-attack. M-learning systems normally comprise three components which are the mobile device, one or multiple servers and network devices. While servers and network infrastructure have...
Emerging large-scale distributed storage systems such as content delivery networks (CDNs) are faced with the task of distributing peta-bytes of requested data from mobile service users. In this paper, we present a novel cache architecture with enhanced performance that aims to reduce the data distribution load on CDNs for large-scale storage systems. Our proposed architecture is located between a...
Recently, as the smartphone market is growing rapidly, the amount of using QR Code with smartphone is increasing together. This paper proposes a new method for improving the rate of QR Code recognition on smartphone. In some angles, sometimes, a few applications cannot recognize QR code. So, this method make it possible to recognize the QR Code any angle. In order to find an original QR Code we proposes...
It has become easier to create a lifelog by using smart phones. Lifelogs can be used in several ways. However, some problems exist in memory recollection; as many lifelogs owned by a person are partial information, it is impractical to remember days themselves. Therefore, a lifelog sharing system for memory recollection is proposed. The system elicits related information from other people's lifelogs...
A recent Pew research center study of mobile device usage revealed that, African American and Latinos are the most active users of the Internet from mobile devices. The study also revealed that minority cell phone owners take advantage of a much greater range of their phone's features compared with people of other ethnicities. At Winston Salem State University (WSSU), it is common for students to...
The rapid pace of change being witnessed globally in the Information and Communication Technology sector as well as the skyrocketing costs in getting basic education needs met have forced many to seek for alternative ways of meeting these needs. Recent innovations in distance education opened up the pathway to new and dynamic ways of learning through Massively Open Online Courses (MOOCs) aimed at...
In Thailand University, checking student attendance is one of the important issues for universities, because many universities evaluate students' attendance and while giving the final grade, professors consider their total number of appearances on classes during the whole semester. This brings to the idea of having some tool to control students' attendance. Some universities prefer to use paper sheet...
This paper deals with exploring of the potential of writer identification by handwriting on a touch-screen phone for an application in access control systems. Our aim was to examine the possibility of writer recognition by a biometric model based on handwritten password. A mobile phone-server solution based on distributed blocks is proposed. The implemented approach performs a pre-processing block,...
The recent advance in cloud computing and mobile devices empowers many innovative e-learning systems or games with increased interactivity and improved features. In this paper, we consider an innovative framework of cloud-based e-learning games that can be assessed through mobile devices to enhance students' learning anytime and anywhere. Being model-based, our proposal is adaptive and highly portable...
Mobile learning is a new stage of distance education, and is the product of the stage in which wireless mobile communication device and wireless mobile communication network technology are developed to be mature. Its main characteristic is the 4A"Anyone Anytime Anywhere Anystyle" free learning style. This paper introduces the concept of Mobile Learning and 3G technology, also describes the...
While a substantial amount of big data are consumed via mobile devices, accessing content via wireless data connections on mobile devices has its own set of challenges. Among these challenges, speed of data transfer is usually our first priority. Although there are many fast data connections available for Web surfing (3G, LTE etc.), the actual connection speed could vary significantly among different...
Mobile cloud computing has been introduced to be a powerful technology for mobile services by combining mobile computing and cloud computing technology. Though, a direct integration of two technologies can overcome a many of hurdles related to the performance, flexibility, security, and dynamic management discussed in mobile computing. Mobile cloud computing can address these problems by executing...
The paper describes architecture of a prototype networked student information delivery system. Main system functionalities include interactive access to lecture room timetables and group messaging. The system exploits modern mobile technologies to allow flexible usage scenarios. The use of open APIs of telecommunications service delivery platforms in combination with e-mail messaging provides diverse...
Some high school students lack a motivation to review the English vocabulary learning in second language after school. However, many studies have pointed out that the game-based learning (GBL) can improve students' learning motivations and effectiveness. We present a digital game-based learning system for high school students' after-school learning in English vocabulary. Teachers should only guide...
This paper describes a server system to support the development of applications with multiple sources of input and output. The framework includes support for different types of mobile communication services and the management of communication between the server and clients, who are mobile phone users. Communication is achieved via readily available mobile communication methods, including SMS and email...
Computations with higher than the IEEE 754 standard double-precision (about 16 significant digits) are required recently. Although some software routines in Fortran or C for high-precision computation are available, users are required to implement such routines in their own computers with knowledges about high-precision computations. In this paper we show an user-friendly online system for octuple-precision...
EHEA guidelines are promoting the modernization of the universities all over Europe, focusing on the implementation of new technologies to get services offered by universities closer to society. With this idea in mind, the Technical University of Cartagena is deeply involved in the development and implementation of the so-called Smart University model: a ubiquitous computing platform based on NFC,...
This paper presents the design and implementation of Asterisk server, which serves as the local exchange for placing voice and video calls within a private Wi-Fi cloud and legacy networks, that is, with the Public Switch Telephony Network (PSTN). The model is accessible within the area of a university campus and allows only those mobile phones and PCs' to connect to the Asterisk server which are registered...
