Mobile applications are usually developed in a native way, using languages and APIs specific for a given platform, hindering the portability. As an alternative, web technologies as JavaScript and PHP have been employed enabling a same implementation to be executed in different mobile platforms without any recompilation or recoding process. This paper compares the efficiency of Android applications...
In recent times, mobile broadband networks are focused on bringing different capabilities to the edge of the mobile network. Mobile Edge Computing (MEC) addresses this issue by placing the compute and storage resources closer to the Radio Access Network (RAN), with an aim to reduce end-to-end latency, ensure better service delivery, and offer improved user experience. In this work, we propose SDEC...
Background. Process mining is a technique to build process models from "execution logs" (i.e., events triggered by the execution of a process). State-of-the-art tools can provide process managers with different graphical representations of such models. Managers use these models to compare them with an ideal process model or to support process improvement. They typically select the representation...
User-generated mobile application reviews have become a gold mine for timely identifying functional defects in this type of software artifacts. In this work, we develop a hidden structural SVM model for extracting detailed defect descriptions from user reviews at the sentence level. Structured features and constraints are introduced to reduce the demand of exhaustive manual annotation at the sentence...
This work presents a new concept of environment mapping aiming to identify dynamic objects in the scene, and then estimate their direction and future position. The motion analysis is performed directly in the traditional 2D costmap through three different map frames. Costmap is a traditional mapping technique that uses an occupation grid is used, where each cell has a degree of uncertainty about whether...
Rapid development of wireless network technologies allows smartphones to take computer's place in many areas. Therefore, the majority of work to be done on the computer can be done via smartphones without place limitation and trouble of carrying computer. Using smartphones on vocational education necessitates mobilizing of modelling studies. This study aims to design a mobile simulation tool by using...
Recently, mobile broadband networks are focused on bringing additional capabilities to the network edge. For instance, Mobile Edge Computing (MEC) brings storage and processing capabilities closer to the mobile user i.e., at the radio access network, in order to deploy services with minimum delay. In this paper, we propose a resource constrained cloud-enabled small cell that includes a MEC server...
In the next decades, hundreds of autonomous ships (AS) and Conventional ships (CS) will cross the Detroit of Gibraltar. For their autonomous operation, and remote control, these ships need to communicate with each other, with the vessel traffic system (VTS), with the port state control (PSC) and with the shore control centre (SCC). For a sustainable maritime industry, the biggest challenge will be...
This paper presents an energy-efficient symmetric block-wise concatenated-BCH (SBC-BCH) decoder architecture for energy-starving mobile storages. The proposed 4KB SBC-BCH code remarkably enhances the hard-decision-based error-correcting performance to defer the energy-consuming memorysensing operations for generating the soft-decision values, which are necessary to prolong the lifetime of flash memories...
We describe a “crowd measurement” project, referred to as PoQeMoN, whose main objective is to identify Quality of Service (QoS) indicators in order to predict the Quality of Experience (QoE) for HTTP YouTube content on mobile networks. Results are based on experiments on an operational network. The second contribution of this paper is to show that the proposed indicator is easy to implement in order...
Requirements of different applications and usage scenarios on a wireless positioning system is very different. A single positioning system is unlikely to meet all the requirements. UWB based positioning systems offer a solution which would meet all the indoor usage requirements. Though, the theoretical positioning accuracy offered by such systems is very good, in actual implementation, their accuracy...
Computer based support for clinical and health-related procedures is growing in the last decades. However, the vast majority of information systems adopted in health structures are legacy systems, which do not often allow to export data easily and also are usually desktop oriented. A growing number of medical instruments are image-oriented and produce a large quantity of image data, typically in the...
In this paper, we consider a Device-to-Device (D2D) cellular network in which idle users can work as relays between cell users and the base station to improve their data rate. The relaying induces a cost for the User Equipment Relays (UER), that should be compensated with a payment from the mobile operator so that UERs accept to offer the service. The problem hence arises for the operator to match...
Recently, several protocols have been proposed to accomplish user authenticity with proper session key establishment in Global Mobility Network. Unfortunately, some of them still suffer from various security threats and high computational complexity. This article demonstrates a new enhanced two-factor authentication scheme for secure anonymous communication to mutually authenticate the communicating...
The vertical handover is an important issue in the world of internet. In fact, the use of internet is becoming wider with the diversity of possible offered services, going from emailing, Data and video transfers, to IoT. The number of internet users has reached multimillions of people these last two decades, in addition, they are willing to connect wirelessly anytime and anywhere, to the best available...
mHealth4Afrika is a collaborative research and innovation project, co-funded under Horizon 2020. It is focused on supporting Sustainable Development Goal 3 and Horizon 2020 Societal challenges by developing, researching and evaluating the potential impact of co-designing an open source, multilingual enabled mHealth platform to support quality community-based primary maternal healthcare delivery at...
Four 5.8 GHz band transceivers at the University of Colorado at Boulder (UCB) were first operated as a wide area local area network (WLAN) in April of 2017. The purpose of this WLAN is to serve as a testbed for installations to be made in the developing world as a part of the IEEE Smart Village program. The configuration of the components is discussed in detail. The testbed is self-powered by solar...
Advances in mobile technologies have led to the use of mobile devices in telemedicine. Examples include smartphones for capturing microscopic images from glass slides for remote telepathology and in teledermatology consultations. As use of smartphones become even more pervasive in developing countries where expert medical consultation is greatly needed, telemedicine, such as telepathology and telemicroscopy...
Mobile devices have been helping to empower underserved communities around the world. From bringing information on health and farming to substituting expensive devices, cellular phones and apps have proved to be powerful tools in poverty alleviation and disaster relief. The Mobile Lab at Santa Clara University focuses on developing mobile solutions for social benefit and, in this paper, we describe...
In this study, a mobile based project depended on client-server communication has developed for the early diagnosis of eye diseases. It is a disadvantage that the technical devices used in the diagnosis of eye diseases are expensive and not portable. For this reason, a mobile based system is proposed in order to make eye examinations more practical and cheap in the study. The estimated pathological...
