Consumer resistance to mobile commerce services

Oheinen opinnäytetyö on kvalitatiivinen tutkimus kuluttajavastarinnasta mobiilin kaupankäynnin palveluja kohtaan. Tutkimus kohdistuu läntisiin kulttuureihin, joissa kyseisen innovatiivisen palveluryhmän leviämistä tukevat monet aikaisemmat innovaatiot kuten matkapuhelin, Internet, digitaaliset pankkipalvelut. Tutkimus esittelee innovaatioiden vastarintatekijöitä ihmisen luonnollisena reaktiona tämän vakiintuneita elämäntapoja mullistavia keksintöjä kohtaan nimenomaan läntisissä kulttuureissa, joissa kuluttajat ovat perinteisesti hyvin teknologiamyönteisiä. Toisaalta tutkimusalueella on havaittavissa sosiaalisten ryhmien pirstoutuminen yhä pienemmiksi alaryhmiksi, mikä voi hidastaa sosiaalista oppimista. Tutkimus vastaa todelliseen tutkimusaukkoon. Aihe on samalla sekä ajankohtainen että relevantti vastatessaan nykyisin käytävään utopistiseen keskusteluun digitaalisen informaatioyhteiskunnan kehittymisestä ja merkityksestä modernille ihmiskunnalle. Tutkimuksen teoreettinen eksploratiivinen viitekehys rakentuu valikoiduista uusien tuotteiden ja palvelujen kehittämisen, palvelumarkkinoinnin ja sosiaalisen oppimisen teorioista sekä innovaatio- kommunikaatioteorioista. Empiirisen osan muodostavat kansainvälisten markkinatutkimuslaitosten ja haastateltujen asiantuntijoiden näkemykset alan kehityksestä. Tutkimus osoittaa, että kuluttajat eivät ole valmiita vastaanottamaan kehittyvien teknologioiden mahdollistamia mobiilin kaupankäynnin palveluita ennen kuin ne vastaavat kuluttajien perustarpeisiin ja rakenteelliset vastarintatekijät (alhainen käytettävyys, matala lisäarvo, koetut riskit, perinnevastarinta, palveluryhmän huono mielikuva) on poistettu. Tutkimus esittää, että mobiilin kaupankäynnin alalla toimivien yritysten tulisi työskennellä yhteistyössä keskenään ja kuluttajien kanssa luodakseen kuluttajien tarpeita ja toiveita vastaavia turvallisiksi koettuja mobiilin kaupankäynnin palveluita. Tutkimus ehdottaa, että kyselytutkimusten ohella käytettäisiin havaintomenetelmiä, jotta teknologiat voitaisiin valjastaa kuluttajien tarpeita ja kulutustottumuksia vastaaviksi.

Varaosien tunnistuspalvelut sähköisessä liiketoimintaympäristössä

Työn tarkoituksena on ollut luoda varaosien tunnistukseen kehitysmalli, jota voidaan käyttää pohjana palveluiden kehityksessä. Saatavilla olevia tunnistusmenetelmiä parantamalla on mahdollista kehittää liiketoimintaprosesseja. Yrityksiin kohdistuu yhä enemmän vaatimuksia, jotka täyttääkseen on kyettävä luomaan kustomoitavissa olevia innovatiivisia palvelukokonaisuuksia. Yritysten tulisi kerätä yhteen kaikki saatavilla oleva tieto asiakkaiden hankkimista tuotteista ja palveluista tarjoten näiden kautta toimintamahdollisuuksia lähemmäs asiakasrajapintaan. Sähköisten tunnistuspalveluiden kehitys ja integrointi yhdeksi kokonaisuudeksi on keskeisessä asemassa yrityksen palvelutarjontaa kehitettäessä. Palveluihin voidaan antaa pääsy SOA (Service Oriented Architecture) -malliin perustuvien portaaleiden kautta. Uudet varaosien tunnistusmenetelmät tulee liittää web-palveluina portaaliin integrointimenetelmiä käyttäen. Varaosien tunnistuksen kannalta on keskeistä linkittää taustajärjestelmien tieto tukemaan tunnistusprosessia tuotteiden koko elinkaaren ajan. Case tapauksessa integroitiin varaosien tunnistuspalveluina IMB WebSphere Portal:n PDM (Product Data Management) -järjestelmän varaosadokumentaatio. Lisäksi luotiin varaosien tunnistusjärjestelmän vaatima datamalli, joka mahdollistaa PDMjärjestelmässä olevan as-built – varaosarakenteen hyväksikäytön portaaliin liitettävän graafisen varaosien tunnistusjärjestelmän kanssa. Tulevaisuuden kehitysmahdollisuuksina nähdään huoltojärjestelmien tiedon integrointi osaksi tunnistusmenetelmiä parantavaa kokonaisuutta, huoltotarpeen automaattinen seuranta ja analysointi, RFID:n käyttömahdollisuudet, mobiili-sovellusten kehitys, varaosien tunnistukseen perustuvien liiketoimintaprosessien automatisointi sekä jatkuva tiedonjaon kehittäminen.

Optimizing Mobile Java Location-Based Services in Symbian OS

This thesis evaluates methods for obtaining high performance in applications running on the mobile Java platform. Based on the evaluated methods, an optimization was done to a Java extension API running on top the Symbian operating system. The API provides location-based services for mobile Java applications. As a part of this thesis, the JNI implementation in Symbian OS was also benchmarked. A benchmarking tool was implemented in the analysis phase in order to implement extensive performance test set. Based on the benchmark results, it was noted that the landmarks implementation of the API was performing very slowly with large amounts of data. The existing implementation proved to be very inconvenient for optimization because the early implementers did not take performance and design issues into consideration. A completely new architecture was implemented for the API in order to provide scalable landmark initialization and data extraction by using lazy initialization methods. Additionally, runtime memory consumption was also an important part of the optimization. The improvement proved to be very efficient based on the measurements after the optimization. Most of the common API use cases performed extremely well compared to the old implementation. Performance optimization is an important quality attribute of any piece of software especially in embedded mobile devices. Typically, projects get into trouble with performance because there are no clear performance targets and knowledge how to achieve them. Well-known guidelines and performance models help to achieve good overall performance in Java applications and programming interfaces.

Means and challenges in international operations for a Finnish mobile application provider

Master’s Thesis concentrates to means and challenges in international operations for a Finnish mobile application provider Small Planet Oy during its various company stages from founding till maturing and during macro economical phases between year 1998 and 2008. Small Planet has just celebrated its 10 year anniversary and is therefore quite an extraordinary company which has survived all the highs and lows during past ten years and which has operated in the market as long as the whole mobile application industry has existed. Master’s Thesis describes possibilities for a company’s internationalization with different entry modes like exporting, licensing, investment entry and co-operative operations which are suitable for a mobile application provider. Unsuitable entry modes like franchising or contract manufacturing are not explained. The goal has been to analyze Small Planet’s international operations and to make conclusions from the practical experiences. Analysis and conclusions shall help Small Planet in its international operations in the future and should give insight to other mobile application companies and their managers who are in the situation of planning their own international operations. Results show that the best ways for Small Planet to internationalize its operations has been the co-operation with a big domestic client and the co-operation with Finnish operator infrastructure providers which have complementary products with Small Planet. Through these co-operations Small Planet has got lot of new international clients. Same time financial risks and investment need for international operations have been low. Co-operative international sales can be the most efficient international entry mode for a mobile application provider.

Handover aspects in Unlicensed Mobile Access Technology

Fixed Mobile Convergence is the recent buzz in the field of telecommunication technology. Unlicensed Mobile Access (UMA) technology is a realistic implementation of Fixed Mobile Convergence. UMA involves communication between different types of networks. Handover is a very important issue in UMA. The study is an analysis of theoretical handover mechanism and practical test results. It includes a new proposal for handover performance test in UMA. It also provides an overview of basic handover operation on different scenarios in UMA. The practical test involves an experiment on handover performance test using network analyzers. The new proposal provides a different approach for an experimental setting on handover performance test without using network analyzers. The approach is not be implemented because of some technical problem in a network equipment in UMA. The analysis of the test results reveals that time of handover between UMA and Global System for Mobile Communication (GSM) network is similar to time of handover between inter base station controller (BSC) handover in GSM networks. The new approach is simple and provides measurement at the end point communicating entities. The study gives a general understanding of handover operation, an analysis of handover performance in UMA and specifically provides a new approach useful for further study of handover in different real world environments and scenarios.

Adaptive optimization schemes for mobile VoIP applications Battery life and call quality aspects

In this thesis programmatic, application-layer means for better energy-efficiency in the VoIP application domain are studied. The work presented concentrates on optimizations which are suitable for VoIP-implementations utilizing SIP and IEEE 802.11 technologies. Energy-saving optimizations can have an impact on perceived call quality, and thus energy-saving means are studied together with those factors affecting perceived call quality. In this thesis a general view on a topic is given. Based on theory, adaptive optimization schemes for dynamic controlling of application's operation are proposed. A runtime quality model, capable of being integrated into optimization schemes, is developed for VoIP call quality estimation. Based on proposed optimization schemes, some power consumption measurements are done to find out achievable advantages. Measurement results show that a reduction in power consumption is possible to achieve with the help of adaptive optimization schemes.

Particle detector link system modifications in RE1/1 sector

The large hadron collider constructed at the European organization for nuclear research, CERN, is the world’s largest single measuring instrument ever built, and also currently the most powerful particle accelerator that exists. The large hadron collider includes six different experiment stations, one of which is called the compact muon solenoid, or the CMS. The main purpose of the CMS is to track and study residue particles from proton-proton collisions. The primary detectors utilized in the CMS are resistive plate chambers (RPCs). To obtain data from these detectors, a link system has been designed. The main idea of the link system is to receive data from the detector front-end electronics in parallel form, and to transmit it onwards in serial form, via an optical fiber. The system is mostly ready and in place. However, a problem has occurred with innermost RPC detectors, located in sector labeled RE1/1; transmission lines for parallel data suffer from signal integrity issues over long distances. As a solution to this, a new version of the link system has been devised, a one that fits in smaller space and can be located within the CMS, closer to the detectors. This RE1/1 link system has been so far completed only partially, with just the mechanical design and casing being done. In this thesis, link system electronics for RE1/1 sector has been designed, by modifying the existing link system concept to better meet the requirements of the RE1/1 sector. In addition to completion of the prototype of the RE1/1 link system electronics, some testing for the system has also been done, to ensure functionality of the design.

Context exchange between devices in mobile environment

Context awareness is emerging on mobile devices. Context awareness can be used to improve usability of a mobile device. Context awareness is particularly important on mobile devices due the limitations they have. At first in this work, a literature review on context awareness and mobile environment is made. For aiding context awareness there exist an implementation of a Context Framework for Symbian S60 devices. It provides a possibility for exchanging the contexts inside the device between the client applications of the local Context Framework. The main contribution of this thesis is to design and implement an enhancement to the S60 Context Framework for providing possibility to exchange context over device boundaries. Using the implemented Context Exchange System, the context exchange is neither depending on the type of the context nor the type of the client. In addition, the clients and the contexts can reside on any interconnected device. The usage of the system is independent of the programming language since in addition to using only Symbian C++ function interfaces it can also be utilized using XML scripts. The Meeting Sniffer application, which uses the Context Exchange System, was also developed in this work. Using this application, it is possible to recognize a meeting situation and suggest device profile change to a user.

Comovement of stock price risk in strategic alliance — Case: mobile internet

The focus of this study has been comovement of stock price risk level between two companies as they form strategic alliance. Thus the main reason has been to shed more light to possible increased risk level that the stockholder confronts when a company he owns forms a strategic alliance with another company. This study has centralized to interfirm cooperation between mobile and internet companies, which have furthered the development of mobile internet. The study has been divided into theoretical and empirical part. In theoretical part the main concepts riskiness of a stock (volatility), comovement and strategic alliance have been run through. In empirical part seven strategic alliances formed by mobile internet companies have been examined. Based on this, strategic alliance seems to increase comovement of stock price risk in some degree. This comovement seems to be stronger when core businesses or operating environments of cooperating companies differ more from each other.

Trigger and data link system for CMS Resistive Plate Chambers at the LHC accelerator

The purpose of the work was to realize a high-speed digital data transfer system for RPC muon chambers in the CMS experiment on CERN’s new LHC accelerator. This large scale system took many years and many stages of prototyping to develop, and required the participation of tens of people. The system interfaces to Frontend Boards (FEB) at the 200,000-channel detector and to the trigger and readout electronics in the control room of the experiment. The distance between these two is about 80 metres and the speed required for the optic links was pushing the limits of available technology when the project was started. Here, as in many other aspects of the design, it was assumed that the features of readily available commercial components would develop in the course of the design work, just as they did. By choosing a high speed it was possible to multiplex the data from some the chambers into the same fibres to reduce the number of links needed. Further reduction was achieved by employing zero suppression and data compression, and a total of only 660 optical links were needed. Another requirement, which conflicted somewhat with choosing the components a late as possible was that the design needed to be radiation tolerant to an ionizing dose of 100 Gy and to a have a moderate tolerance to Single Event Effects (SEEs). This required some radiation test campaigns, and eventually led to ASICs being chosen for some of the critical parts. The system was made to be as reconfigurable as possible. The reconfiguration needs to be done from a distance as the electronics is not accessible except for some short and rare service breaks once the accelerator starts running. Therefore reconfigurable logic is extensively used, and the firmware development for the FPGAs constituted a sizable part of the work. Some special techniques needed to be used there too, to achieve the required radiation tolerance. The system has been demonstrated to work in several laboratory and beam tests, and now we are waiting to see it in action when the LHC will start running in the autumn 2008.

Social Networking on Mobile Environment on top of PeerHood

Social networking and social networking sites have gained popularity among internet users during the past few years. Social networks fulfill the need of users to stay connected to friends and other people interested in the same issues. Combining social networks to the mobile environment is a growing interest of mobile device users as it allows the users to be in their online social community despite their mobility. This thesis highlights the basics of mobile environment, social networking and PeerHood and introduces a new approach of social networking on mobile environment, which is a new concept in mobile social networking. This approach is based on dynamic group discovery in accordance to some common user interests and management in the PeerHood environment. A reference implementation of a social networking application built on top of PeerHood is presented and it is tested and analyzed to understand the social networking on mobile environment and the new concept of dynamic group discovery in it.

Mobile Subscription Acquisition and Retention Costs - An Actvity-Based Model

The objective of this master’s thesis was to develop a model for mobile subscription acquisition cost, SAC, and mobile subscription retention cost, SRC, by applying activity-based cost accounting principles. The thesis was conducted as a case study for a telecommunication company operating on the Finnish telecommunication market. In addition to activity-based cost accounting there were other theories studied and applied in order to establish a theory framework for this thesis. The concepts of acquisition and retention were explored in a broader context with the concepts of customer satisfaction, loyalty and profitability and eventually customer relationship management to understand the background and meaning of the theme of this thesis. The utilization of SAC and SRC information is discussed through the theories of decision making and activity-based management. Also, the present state and future needs of SAC and SRC information usage at the case company as well as the functions of the company were examined by interviewing some members of the company personnel. With the help of these theories and methods it was aimed at finding out both the theory-based and practical factors which affect the structure of the model. During the thesis study it was confirmed that the existing SAC and SRC model of the case company should be used as the basis in developing the activity-based model. As a result the indirect costs of the old model were transformed into activities and the direct costs were continued to be allocated directly to acquisition of new subscriptions and retention of old subscriptions. The refined model will enable managing the subscription acquisition, retention and the related costs better through the activity information. During the interviews it was found out that the SAC and SRC information is also used in performance measurement and operational and strategic planning. SAC and SRC are not fully absorbed costs and it was concluded that the model serves best as a source of indicative cost information. This thesis does not include calculating costs. Instead, the refined model together with both the theory-based and interview findings concerning the utilization of the information produced by the model will serve as a framework for the possible future development aiming at completing the model.
