A Survey on Proxy Mobile IPv6 Handover
2016
[EN] As wireless technologies have been improving in recent years, a mobility management mechanism is required to provide seamless and ubiquitous mobility for end users who are roaming among points of attachment in wireless networks. Thus, Mobile IPv6 was developed by the Internet Engineering Task Force (IETF) to support the mobility service. However, Mobile IPv6 is unable to fulfill the requirements of real-time applications, such as video streaming service and voice over IP service, due to its high handover (HO) latency. To address this problem, Proxy Mobile IPv6 (PMIPv6) has been introduced by the IETF. In PMIPv6, which is a network-based approach, the serving network controls mobility m…
A New Approach for the Reliability of Vehicular Ad Hoc Networks
2018
Vehicular ad hoc networks (VANET), a subset of Mobile Ad hoc Networks (MANETs), is a wireless communication technology applied to transportation, referring to a set of smart vehicles used on the road. These vehicles provide communication services among one another (V2V) or with Road Side Infrastructure (V2I). The main benefits of VANET are enhancing road safety, reducing energy use and emissions, and giving information services. Reliability is one of the most critical issues related to VANET since the information transmitted is distributed in an open access environment. We focused in this paper, on the reliability of VANET as a function of reliable hardware and their functionality taking in…
A systematic review of handheld tools in lieu of colposcopy for cervical neoplasia and female genital schistosomiasis
2020
Abstract Background Visualization of the lesions in the lower genital tract is the mainstay for diagnosis of the four lesions found in female genital schistosomiasis (FGS), but colposcopes are generally not available in low‐resource settings. Objective We sought to review handheld devices that could potentially be used for FGS diagnosis. Search strategy We searched Medline and Embase 2015–2019 for handheld devices used in cervical cancer screening and FGS diagnosis. Selection criteria We excluded studies that did not compare the device to standard‐of‐care colposcopes or histopathology. Main results and conclusion In 11 studies, four handheld colposcopes, two smartphones, and one compact dig…
The Co‐mutational Spectrum Determines the Therapeutic Response in Murine FGFR2 Fusion‐Driven Cholangiocarcinoma
2021
Background and aims Intrahepatic cholangiocarcinoma (ICC) is the second most common primary liver cancer and a highly lethal malignancy. Chemotherapeutic options are limited, but a considerable subset of patients harbors genetic lesions for which targeted agents exist. Fibroblast growth factor receptor 2 (FGFR2) fusions belong to the most frequent and therapeutically relevant alterations in ICC, and the first FGFR inhibitor was recently approved for the treatment of patients with progressed, fusion-positive ICC. Response rates of up to 35% indicate that FGFR-targeted therapies are beneficial in many but not all patients. Thus far, no established biomarkers exist that predict resistance or r…
The development of mobile banking services in a large Finnish financial organization
2018
The chapter, based on an ongoing qualitative study, provides answers to the following questions: what are the case organizations’ rationales in developing mobile banking services? how are customer perspectives considered in developing them? and what are the implications of digitalization and m-banking for the bank and the client? Based on the findings, m-banking is seen to allow ubiquitous availability and efficiency of service provision, offering a sound rationale for their development. The flipside is that digital and m-banking services dilute the human interaction, which challenges the rationale of improving the customer experience. The service development follows the software industry m…
Assessment of Mobile Money Enablers in Nigeria
2018
This chapter describes how mobile money is an emerging and innovative financial service delivery mechanism. With huge success, recorded mostly in the developing economies, it is scholarly unclear the antecedents of its adoption. Using a survey of 151 respondents comprising both the banked and underbanked in the South-Western part of Nigeria, the authors used the PLS-SEM to test the research hypothesis. The results reveal the enablers of mobile money, which are social influence, performance expectancy, security and effort expectancy, and inhibitors such as system anxiety and cost. Privacy, trust, image and convenience were not found significant in this study. Social influence, performance ex…
“If you take away my phone, you take away my life...” Community Narratives about the Social Implications of Mobile phone Usage for Livelihood Security
2019
Smallholder farmers in developing regions like sub-Saharan Africa still grapple with development challenges like poverty, illiteracy, food insecurity, poor infrastructures like roads and limited access to learning opportunities. Moreover, amidst all these challenges, these possess mobile phones as they continuously engage in diverse livelihood activities. Echoed in previous research, mobile phones are the most diffused technologies available in many rural communities. Yet, most mobile technological interventions are urban-based projects neglecting rural locales in harnessing mobile phone usage. More so, mobile for development research uses quantitative methods which limits proper interrogat…
Resource-efficient hardware implementation of a neural-based node for automatic fingerprint classification
2017
Modern mobile communication networks and Internet of Things are paving the way to ubiquitous and mobile computing. On the other hand, several new computing paradigms, such as edge computing, demand for high computational capabilities on specific network nodes. Ubiquitous environments require a large number of distributed user identification nodes enabling a secure platform for resources, services and information management. Biometric systems represent a useful option to the typical identification systems. An accurate automatic fingerprint classification module provides a valuable indexing scheme that allows for effective matching in large fingerprint databases. In this work, an efficient em…
Usability analysis of a novel biometric authentication approach for android-based mobile devices
2014
Mobile devices are widely replacing the standard personal computers thanks to their small size and user-friendly use. As a consequence, the amount of information, often confidential, exchanged through these devices is raising. This makes them potential targets of malicious network hackers. The use of simple passwords or PIN are not sufficient to provide a suitable security level for those applications requiring high protection levels on data and services. In this paper a biometric authentication system, as a running Android application, has been developed and implemented on a real mobile device. A system test on real users has been also carried out in order to evaluate the human-machine int…
Dopo la firmitas. Prospettiva metabolista di architetture resilienti
2019
Identificata per millenni attraverso la sua capacità di durare identica nel tempo – secondo il paradigma della firmitas vitruviana - l’architettura contemporanea è invece chiamata oggi ad un adattamento dinamico alle mutazioni del suo contesto. L’emergenza climatica è l’epifenomeno più evidente fra quelli che hanno orientato la disciplina verso l’indeterminatezza programmatica, la flessibilità morfologica, gli approcci sistemici aperti. Lontana dall’essere un semplice adeguamento tecnico a nuove esigenze quantitative, l’architettura resiliente chiarisce progressivamente i suoi termini teorici e le sue derivazioni culturali. Un approccio genealogico che traccia la riformulazione di alcuni te…
