SDN/NFV-enabled satellite communications networks: opportunities, scenarios and challenges

In the context of next generation 5G networks, the satellite industry is clearly committed to revisit and revamp the role of satellite communications. As major drivers in the evolution of (terrestrial) fixed and mobile networks, Software Defined Networking (SDN) and Network Function Virtualisation (NFV) technologies are also being positioned as central technology enablers towards improved and more flexible integration of satellite and terrestrial segments, providing satellite network further service innovation and business agility by advanced network resources management techniques. Through the analysis of scenarios and use cases, this paper provides a description of the benefits that SDN/NFV technologies can bring into satellite communications towards 5G. Three scenarios are presented and analysed to delineate different potential improvement areas pursued through the introduction of SDN/NFV technologies in the satellite ground segment domain. Within each scenario, a number of use cases are developed to gain further insight into specific capabilities and to identify the technical challenges stemming from them.Peer ReviewedPostprint (author's final draft

Troli tong gas

Tong gas adalah sebahagian daripada keperluan rumah yang sangat penting untuk kegunaan dapur. LPG (Liquefied Petroleum Gas), atau petroleum gas biasanya digunakan untuk aplikasi perumahan (tong gas masak) dan tujuan komersial. LPG terutamanya terdiri daripada campuran hidrokarbon seperti propana (C3H8), propene (C3H6), n-butana (C4H10), isobutena (metil-propana), dan pelbagai butanes lain (C4H8) (Mustapa, Gitano Briggs, 2008). LPG disimpan cair dalam tong pada tekanan tinggi, tekanan wap sekitar 6 hingga 7 bar (Petrolium Nasional Berhad, 2013). Oleh itu, tong gas perlu diperbuat daripada silinder keluli bertekanan tinggi. Tong gas digunakan hampir di semua perumahan, termasuk rumah pangsa, kondominium dan apartment. Kebiasaan penghuni perumahan bertingkat yang tidak mempunyai lift terpaksa mengangkat tong gas menggunakan tenaga empat kerat, kadang kala menggunakan troli biasa untuk menggangkut tong gas tersebut bagi memudahkan dan meringankan kerja. Troli adalah peranti yang digunakan untuk membawa beban atau memindahkan bahan dari satu tempat ke yang lain. Untuk aplikasi yang berbeza pelbagai jenis troli digunakan Kebanyakan pekerja domestik juga menggunakan tenaga tulang empat kerat untuk kerja-kerja pemindahan troli .

Economic location-based services, privacy and the relationship to identity

Mobile telephony and mobile internet are driving a new application paradigm: location-based services (LBS). Based on a person’s location and context, personalized applications can be deployed. Thus, internet-based systems will continuously collect and process the location in relationship to a personal context of an identified customer. One of the challenges in designing LBS infrastructures is the concurrent design for economic infrastructures and the preservation of privacy of the subjects whose location is tracked. This presentation will explain typical LBS scenarios, the resulting new privacy challenges and user requirements and raises economic questions about privacy-design. The topics will be connected to “mobile identity” to derive what particular identity management issues can be found in LBS

Technology and Service Quality in the Banking Industry: An Empirical Study of Various Factors in Electronic Banking Services

Technology-based self service has greatly changed the way that service Firms and consumers interact and are raising a host of research and practice issues relating to the delivery of e-service which has become increasingly important not only in determining the success or failure of electronic commerce but also in providing consumers with a superior experience with respect to the interactive flow of information. The purpose of this research study was to establish the relationship between technology and service quality in the banking industry in Nigeria. The research was carried out through a cross sectional smvey design which questioned respondents one e-banking services. The population of study mainly constituted of customers of Oceanic bank within Lagos metropolis and its environs. The respondents of the study were customers of banks using e-banking services (internet banking, mobile banking and AIM). The sample in this study consisted of 120 respondents who are users of thee-banking services. The data collected was analyzed by use of frequency, percentage, means and correlation analysis. The findings revealed that secure services as the most important dimension, followed by convenient location of AIM, efficiency (not need to wait, ability to set up accounts so that the customer can perform transactions immediately, accurately of records, user friendly, ease of user, complaint satisfaction, accurate transactions and operation in 24 h)

Designing a smooth service experience: Finding the balance between online and offline service

Tutkimuksen tavoitteena on selvittää, kuinka digitaalisen ja analogisen palvelun voi paremmin yhdistää kokonaispalveluksi niin, että asiakas saa mahdollisimman sujuvan palvelukokemuksen. Tutkimuksen aihe nousee Tunteesta arvoa palvelulle –hankkeesta, jossa toteutettiin palvelumuotoilun kehitysprojekteja yhdessä viiden yrityksen kanssa. Niistä useammassa konseptien osana oli digitaalinen palvelu, mutta haasteeksi nousi digitaalisen kanavan yhdistäminen analogiseen, eli fyysisessä tilassa tapahtuvaan palveluun. Nykypäivänä digitaalisten palveluiden yleisyys on kasvanut ja ihmiset ovat yhä tottuneempia käyttämään digitaalisia kanavia osana palvelukokonaisuutta. Toisaalta käyttäjät ovat myös tietoisia digitaalisten kanavien tarjoamista mahdollisuuksista ja siten heidän odotuksensa ja vaatimuksensa palvelua kohtaan kasvavat. Eri palvelukanavien välillä on kuitenkin havaittavissa eroavaisuuksia ja siten yhtenäisen ja sujuvan palvelukokemuksen syntyminen asiakkaalle on vaikeaa. Asiakkaan tarpeiden ja odotusten sekä yrityksen tavoitteiden huomioiden palvelupolun luomisessa mahdollistavat palvelun sujuvan etenemisen palvelukanavien välillä. Tässä on laadullisessa tutkimuksessa tutkimusaineisto on kerätty puolistrukturoituina teemahaastatteluina. Tutkimusaineisto on analysoitu teemoittelemalla ja tutkimuksen löydökset vastaavat kysymyksiin, miten sujuva palvelukokemus muotoillaan palvelumuotoilun menetelmin, ja miten digitaalisia ja analogisia palvelukanavia tasapainotetaan palvelupolussa. Tutkimuksen tuloksen muodostaa seitsemästä osasta koostuva työkalu, jonka tarkoituksena on toimia palvelun muotoilun ja kehittämisen tukena.While working as a research assistant in Value through Emotion research project at University of Lapland and doing service design projects with several companies, I noticed that there is a challenge in designing a service that combines online and offline service channels. Nowadays the trend is to have an online service, such as service application, as a part of the overall service path, but there is often a gap between the online and offline elements of the service in regards of the communication and the quality of service delivery. The customers are more and more used to digital service channels and they are aware of the possibilities that online channels can provide. Therefore the customers have high expectations about the service delivery. Designing a service that keeps the continuity throughout the service despite the form of delivery channel would be a solution for providing the customer a smooth service experience. In this research I study how a smooth service experience can be built using service design methods. I also study how the balance between online and offline service channels can be found in the overall service path. The research data of partly structured theme interviews are analysed by qualitative research methods. As a result for this case study I present a toolkit with seven templates that can be used as a guideline and support in the service design process when combining online and offline service elements as a smooth service experience
