Platform as a Service - new opportunities for software development companies

Today cloud computing is the next stage in development information-oriented society in field of information technologies. Great attention is paid to cloud computing in general, but the lack of scientific consideration to components brings to the problem, that not all aspects are well examined. This thesis is an attempt to consider Platform as a Service (a technology of providing development environment through the Internet) from divergent angles. Technical characteristics, costs, time, estimation of effectiveness, risks, strategies that can be applied, migration process, advantages and disadvantages and the future of the approach are examined to get the overall picture of cloud platforms. During the work literature study was used to examine Platform as a Service, characteristics of existent cloud platforms were explored and a model of a typical software development company was developed to create a scenario of migration to cloud technologies. The research showed that besides all virtues in reducing costs and time, cloud platforms have some significant obstacles in adoption. Privacy, security and insufficient legislation impede the concept to be widespread.

Marketing plan for a new service concept: case Taksipalvelu MPS Oy

Markkinointisuunnitelmatutkimukset koostuvat pääosin tuotantoalalle tai suurille yrityksille tehdyistä markkinointisuunitelmista. Vaikuttaa siltä, että pienet yritykset tekevät suunnitelmansa ilman nimenomaisesti heille suunniteltua mallia, jos tekevät suunnitelmaa ollenkaan. Kuten sanottu, sovellukset palveluyrityksille ja pk-yrityksille puuttuvat markkinointisuunnitelmiin kohdistuvasta tutkimuksesta, mikä lisää tämän tutkimuksen arvoa keskittyen juuri kyseisiin markkinointisuunnitelman osa-alueisiin. Tutkimusta sovelletaan uuteen palvelukonseptiin, jota case-yritys Taksipalvelu MPS Oy on lanseeraamassa. Palvelu on kohdistettu venäläisille matkailijoille sekä Lappeenrannan alueella eläville venäläisille, ja se perustuu ennen kaikkea korkeaan laatuun. Tutkimus on tärkeä, sillä taksiala on hyvin säännelty, mutta säännöstelyn piirissä on todennäköisesti paljon potentiaalia palveluiden differentaatioon. Segmentointi ja palveluiden kohdistus tiettyihin asiakasryhmiin on taksialalla myös hyvin minimaalista. Tutkimalla kohdistetun palvelun kysyntää ja arvoa saadaan selville olisiko tällainen toiminta kannattavaa vai ei. Venäläisten asiakkaiden määrä on kasvanut Lappeenrannan alueella paljon, minkä potentiaalia ei ole ehkä vielä täysin hyödynnetty. Tutkimuksen tarkoituksena on luoda hyödyllinen markkinointisuunnitelma case-yritykselle kiinnittäen erityisesti huomiota toimialaan ja kohdeasiakasryhmään. Tarkoituksena on antaa suuntaviivoja kuinka lähestyä kohdeasiakkaita ja kuinka markkinoida palvelua oikein. Tavoitteena on myös selvittää onko valitulla asiakassegmentillä kysyntää vai tulisiko kohdistaminen tehdä toisia määritteitä käyttäen.

A design and a prototype for a mobile information service for tourists

Tourism is one of the biggest industry branches with billions of tourists traveling every year around the world. Therefore, solutions providing tourist information have to be up to date with both changes in the industry and the world’s technological progress. The aim of this thesis is to present a design and a prototype of a tourist mobile service which is individual-oriented, cost-free for the end user, and secure. On the information providers’ side, the solution is implemented as a Webbased database. The end users access the information through a Bluetooth application on their mobile devices. The Bluetooth-based solution allows to avoid any costs for the end users, that is tourists. The study shows that, even with small data transfers, the tourists could save significantly when compared to possible roaming charges for data transfer. Also, the proposed mobile service is not intrusive, as it is provided through an application installed by tourists voluntarily on their mobile devices. Through design and implementation this work shows that it is possible to build a system which can be used to provide information services to tourists through mobile phones. The work achieved a successful ongoing synchronization between the client and the server databases. Implementation and usage were limited to smart phones only, as they provide better technological support for the solution having features like maps, GPS, Wi-Fi, Bluetooth and Databases. Moreover, the design of this system shows how Bluetooth technology can be used effectively as a means of communication while minimizing its shortcomings and risks, such as security, by bypassing Bluetooth server service discovery protocol (SDP) and connecting directly to the device. Apart from showing the design and implementation of the end-user costfree mobile information service, the results of this work also highlight the possible business opportunities to the provider of the service.

Building object-oriented software with the D-Bus messaging system

Object-oriented programming is a widely adopted paradigm for desktop software development. This paradigm partitions software into separate entities, objects, which consist of data and related procedures used to modify and inspect it. The paradigm has evolved during the last few decades to emphasize decoupling between object implementations, via means such as explicit interface inheritance and event-based implicit invocation. Inter-process communication (IPC) technologies allow applications to interact with each other. This enables making software distributed across multiple processes, resulting in a modular architecture with benefits in resource sharing, robustness, code reuse and security. The support for object-oriented programming concepts varies between IPC systems. This thesis is focused on the D-Bus system, which has recently gained a lot of users, but is still scantily researched. D-Bus has support for asynchronous remote procedure calls with return values and a content-based publish/subscribe event delivery mechanism. In this thesis, several patterns for method invocation in D-Bus and similar systems are compared. The patterns that simulate synchronous local calls are shown to be dangerous. Later, we present a state-caching proxy construct, which avoids the complexity of properly asynchronous calls for object inspection. The proxy and certain supplementary constructs are presented conceptually as generic object-oriented design patterns. The e ect of these patterns on non-functional qualities of software, such as complexity, performance and power consumption, is reasoned about based on the properties of the D-Bus system. The use of the patterns reduces complexity, but maintains the other qualities at a good level. Finally, we present currently existing means of specifying D-Bus object interfaces for the purposes of code and documentation generation. The interface description language used by the Telepathy modular IM/VoIP framework is found to be an useful extension of the basic D-Bus introspection format.

A Framework for IT Service Management Integration

The objective of this Master’s Thesis is to find out best practices for IT service management integration. Integration in this context means process integration between an IT organization and an integration partner. For observing the objective, two different perspectives are assigned: process and technology. The thesis consists of theory, framework, implementation, and analysis parts. The first part introduces common methodology of IT service management and enterprise integration. The second part presents an integration framework for ITSM integration. The third part illustrates how the framework is used and the last part analyses the framework. The major results of this thesis were the framework architecture, the framework tools, the implementation model, the testing model, and the deployment model for ITSM integration. As a fundamental best practice, the framework contained a four-division structure between architecture, process, data, and technology. This architecture provides a baseline for ITSM integration design, implementation and testing.

Developing the Product Return Process of a Service Center With Lean Methods

Today lean-philosophy has gathered a lot of popularity and interest in many industries. This customer-oriented philosophy helps to understand customer’s value creation which can be used to improve efficiency. A comprehensive study of lean and lean-methods in service industry were created in this research. In theoretical part lean-philosophy is studied in different levels which will help to understand its diversity. To support lean, this research also presents basic concepts of process management. Lastly theoretical part presents a development model to support process development in systematical way. The empirical part of the study was performed by performing experimental measurements during the service center’s product return process and by analyzing this data. Measurements were used to map out factors that have a negative influence on the process flow. Several development propositions were discussed to remove these factors. Problems mainly occur due to challenges in controlling customers and due to the lack of responsibility and continuous improvement on operational level. Development propositions concern such factors as change in service center’s physical environment, standardization of work tasks and training. These factors will remove waste in the product return process and support the idea of continuous improvement.

Customer orientation of sales personnel: Implications for service quality

Prior customer orientation research has concentrated mainly on studying the economical potential of customer orientation to companies. Service quality research instead has concentrated on emphasizing the evaluation of service quality from the customer’s perspective. This means that the service providers lack important information regarding customer orientation and service quality they would need for managerial purposes such as selecting and training employees. Therefore, there is an emerging need to study how customer orientation and service quality relate to company processes, policies and employees, and this study answers to those calls. The objective of this study was to examine what is the role of sales personnel’s’ customer orientation in quality of service delivery and what features support the development of customer orientation among sales personnel. Also the components customer orientation were studied extensively in order to understand how they relate to service quality. The empiric part of the study was conducted as a qualitative research by interviewing seven sales people from operative, tactical and strategic levels of the case corporation in order to get a broader view for customer orientation. The findings propose that both organizational factors and individual factors are affecting customer orientation construct inseparably. Organizational factors are bundled in this study under standards, support and systems, whereas individual factors are formed of employees’ personal attributes, motivation and self-perceived decision making authority. The findings suggest that in the service delivery process at an operative level, customer orientation appears largely in the employees’ individualistic characteristics. Their social and technical skills and motivation to serve customers are the most identifiable factors for customer orientation and consequently, quality service. However, organizational standards, support and systems are strongly dictating the frames the operative sales people operate in, having an influence on how the employees are experiencing their decision making authority and in the end, customer orientation. When looking at the service delivery process at tactical and strategic levels, customer orientation is affecting mainly in the organizational constructs through setting standards, support and systems. However, tactical and strategic level employees influence the operative level through individual customer orientation components as well. The findings indicate that their emotion and personal interaction skills are affecting the overall service delivery process mainly through supervisor support and motivation of the operative level employees. Based on this study it can be argued that an organization can operate as a facilitator and create certain frames for customer oriented sales behavior through standards, support and systems. However, as the impact of individual customer orientation factors on sales people’s service quality seems decisive, from an organizational perspective it puts pressures on the recruitment.

Development of an Ecology-Oriented Software-Defined Networking Framework

ICT contributed to about 0.83 GtCO2 emissions where the 37% comes from the telecoms infrastructures. At the same time, the increasing cost of energy has been hindering the industry in providing more affordable services for the users. One of the sources of these problems is said to be the rigidity of the current network infrastructures which limits innovations in the network. SDN (Software Defined Network) has emerged as one of the prominent solutions with its idea of abstraction, visibility, and programmability in the network. Nevertheless, there are still significant efforts needed to actually utilize it to create a more energy and environmentally friendly network. In this paper, we suggested and developed a platform for developing ecology-related SDN applications. The main approach we take in realizing this goal is by maximizing the abstractions provided by OpenFlow and to expose RESTful interfaces to modules which enable energy saving in the network. While OpenFlow is made to be the standard for SDN protocol, there are still some mechanisms not defined in its specification such as settings related to Quality of Service (QoS). To solve this, we created REST interfaces for setting of QoS in the switches which can maximize network utilization. We also created a module for minimizing the required network resources in delivering packets across the network. This is achieved by utilizing redundant links when it is needed, but disabling them when the load in the network decreases. The usage of multi paths in a network is also evaluated for its benefit in terms of transfer rate improvement and energy savings. Hopefully, the developed framework can be beneficial for developers in creating applications for supporting environmentally friendly network infrastructures.

The neo-liberal state and the crisis of public service broadcasting in the Anglo-American democracies /

The NeO'liberal State and the Crisis ofPublic Service Broadcasting in the Anglo-American Democracies The purpose ofthis analysis ofthe present condition ofpublic service broadcasting in the Anglo- American democracies was to investigate whether such media can still be regarded as the primarypublic spherefor a dialogue between each nation 's civil society and the State. The motivationfor this thesis was based on a presumption that such fora for public discussion on the central issues of each society have become viewed as less relevant bypoliticians andpolicy-makers and thepublics they were intended to serve in the Anglo-American democracies over thepast two decades. It is speculated that this is the case because ofa beliefthat the post-war consensus between the respective States andpublics that led to the construction of the Keynesian Welfare State and the notion ofpublic service broadcasting has been displaced by an individualistic, neo-liberal, laissez-faire ideology. In other words, broadcasting as a consumer-oriented, commercial commodity has superseded concerns pertaining to the importance ofthe public interest. The methodology employed in this thesis is a comparative analysisfrom a criticalpolitical economy perspective. It was considered appropriate to focus on the United Kingdom, Australia, Canada and the\ United States because they comprise the four largest Anglo-American nations with democratic political systems andprimarily market economies. Justificationfor this particular sample is reinforced by thefact that case study countries also share a common socio-political and economic tradition. The evidence assembledfor this thesis consisted almost exclusively ofexisting literature on the subjects ofpublic service broadcasting, global economic andpolitical integration, and the ascendance ofthe 'free-market ' ethos in Western democracies since the late mid- to late-1970s. In essence, this thesis could be considered as a reinterpretation ofthe existing literature relevant to these issues. Several important common features werefound among the political, economic and broadcasting systems of the four case study nations. It is proposed that the prevalence of the neo-liberal world view throughout the political and policy environments of the four countries has undermined the stability and credibility of each nation 's national public service broadcasting organization, although with varying intensity and effect,. Deregulation ofeach nation 's broadcasting system and the supremacy ofthe notion of 'consumer sovereignty' have marginalized the view of broadcasting on any basis other than strictly economic criteria in thefour case study countries. This thesis concludes that,for a reconstruction ofa trulyparticipatory anddemocraticpublicsphere to be realized in the present as well as thefuture, a reassessment ofthe conventional concept ofthe 'public sphere ' is necessary. Therefore, it is recommended that thefocus ofpolicy-makers in each Anglo-American democracy be redirectedfrom that which conceived ofan all-encompassing, large, state-ownedand operated public broadcasting service toward a view which considers alternativeforms ofpublic communication, such as local community and ethnic broadcasting operations, that are likely to be more responsive to the needs of the increasingly diverse and heterogeneous populations that comprise the modem Anglo-American democracies. The traditional conception of public broadcasters must change in accordance with its contemporary environment if the fundamental principles of the public sphere and public service broadcasting are to be realized.

When job dissatisfaction leads to customer-oriented citizenship behaviors

This thesis places boundary conditions on the withdrawal model in the frontline setting of service organizations by considering continuance commitment and supervisory support as moderators of the relationship between job dissatisfaction and customer-oriented citizenship behaviors (COCBs). Departing from traditional research in the areas of the service-profit chain and employee withdrawal, the author advances our understanding of conditions that may lead frontline service employees who are dissatisfied to deposit COCBs into the organizational system. Specifically, based on principles derived from social exchange theory, high continuance commitment and high supervisory support are expected to lead to COCBs, because under this condition the benefits of performing such behaviors are increased (i.e., promotion-based, reciprocity-based), while the costs are decreased (i.e., opportunity costs). Utilizing a sample of 127 frontline employees from both the financial services and travel agency industries, the hypothesized relationships are empirically supported using moderated hierarchical regression analysis. To conclude discussion, implications of the results for both academics and p

Identification d’une architecture à base de composants dans une application orientée objets à l’aide d’une analyse dynamique

Un système, décrit avec un grand nombre d'éléments fortement interdépendants, est complexe, difficile à comprendre et à maintenir. Ainsi, une application orientée objet est souvent complexe, car elle contient des centaines de classes avec de nombreuses dépendances plus ou moins explicites. Une même application, utilisant le paradigme composant, contiendrait un plus petit nombre d'éléments, faiblement couplés entre eux et avec des interdépendances clairement définies. Ceci est dû au fait que le paradigme composant fournit une bonne représentation de haut niveau des systèmes complexes. Ainsi, ce paradigme peut être utilisé comme "espace de projection" des systèmes orientés objets. Une telle projection peut faciliter l'étape de compréhension d'un système, un pré-requis nécessaire avant toute activité de maintenance et/ou d'évolution. De plus, il est possible d'utiliser cette représentation, comme un modèle pour effectuer une restructuration complète d'une application orientée objets opérationnelle vers une application équivalente à base de composants tout aussi opérationnelle. Ainsi, La nouvelle application bénéficiant ainsi, de toutes les bonnes propriétés associées au paradigme composants. L'objectif de ma thèse est de proposer une méthode semi-automatique pour identifier une architecture à base de composants dans une application orientée objets. Cette architecture doit, non seulement aider à la compréhension de l'application originale, mais aussi simplifier la projection de cette dernière dans un modèle concret de composant. L'identification d'une architecture à base de composants est réalisée en trois grandes étapes: i) obtention des données nécessaires au processus d'identification. Elles correspondent aux dépendances entre les classes et sont obtenues avec une analyse dynamique de l'application cible. ii) identification des composants. Trois méthodes ont été explorées. La première utilise un treillis de Galois, la seconde deux méta-heuristiques et la dernière une méta-heuristique multi-objective. iii) identification de l'architecture à base de composants de l'application cible. Cela est fait en identifiant les interfaces requises et fournis pour chaque composant. Afin de valider ce processus d'identification, ainsi que les différents choix faits durant son développement, j'ai réalisé différentes études de cas. Enfin, je montre la faisabilité de la projection de l'architecture à base de composants identifiée vers un modèle concret de composants.

Management of Traffic Control — A Computer Oriented Approach

Traffic Management system (TMS) comprises four major sub systems: The Network Database Management system for information to the passengers, Transit Facility Management System for service, planning, and scheduling vehicle and crews, Congestion Management System for traffic forecasting and planning, Safety Management System concerned with safety aspects of passengers and Environment. This work has opened a rather wide frame work of model structures for application on traffic. The facets of these theories are so wide that it seems impossible to present all necessary models in this work. However it could be deduced from the study that the best Traffic Management System is that whichis realistic in all aspects is easy to understand is easy to apply As it is practically difficult to device an ideal fool—proof model, the attempt here has been to make some progress-in that direction.

Knowledge Building in Landscape Architecture

The objective of this study was to develop an internet-based seminar framework applicable for landscape architecture education. This process was accompanied by various aims. The basic expectation was to keep the main characteristics of landscape architecture education also in the online format. On top of that, four further objectives were anticipated: (1) training of competences for virtual team work, (2) fostering intercultural competence, (3) creation of equal opportunities for education through internet-based open access and (4) synergy effects and learning processes across institutional boundaries. This work started with the hypothesis that these four expected advantages would compensate for additional organisational efforts caused by the online delivery of the seminars and thus lead to a sustainable integration of this new learning mode into landscape architecture curricula. This rationale was followed by a presentation of four areas of knowledge to which the seminar development was directly related (1) landscape architecture as a subject and its pedagogy, (2) general learning theories, (3) developments in the ICT sector and (4) wider societal driving forces such as global citizenship and the increase of open educational resources. The research design took the shape of a pedagogical action research cycle. This approach was constructive: The author herself is teaching international landscape architecture students so that the model could directly be applied in practice. Seven online seminars were implemented in the period from 2008 to 2013 and this experience represents the core of this study. The seminars were conducted with varying themes while its pedagogy, organisation and the technological tools remained widely identical. The research design is further based on three levels of observation: (1) the seminar design on the basis of theory and methods from the learning sciences, in particular educational constructivism, (2) the seminar evaluation and (3) the evaluation of the seminars’ long term impact. The seminar model itself basically consists of four elements: (1) the taxonomy of learning objectives, (2) ICT tools and their application and pedagogy, (3) process models and (4) the case study framework. The seminar framework was followed by the presentation of the evaluation findings. The major findings of this study can be summed up as follows: Implementing online seminars across educational and national boundaries was possible both in term of organisation and technology. In particular, a high level of cultural diversity among the seminar participants has definitively been achieved. However, there were also obvious obstacles. These were primarily competing study commitments and incompatible schedules among the students attending from different academic programmes, partly even in different time zones. Both factors had negative impact on the individual and working group performances. With respect to the technical framework it can be concluded that the majority of the participants were able to use the tools either directly without any problem or after overcoming some smaller problems. Also the seminar wiki was intensively used for completing the seminar assignments. However, too less truly collaborative text production was observed which could be improved by changing the requirements for the collaborative task. Two different process models have been applied for guiding the collaboration of the small groups and both were in general successful. However, it needs to be said that even if the students were able to follow the collaborative task and to co-construct and compare case studies, most of them were not able to synthesize the knowledge they had compiled. This means that the area of consideration often remained on the level of the case and further reflections, generalisations and critique were largely missing. This shows that the seminar model needs to find better ways for triggering knowledge building and critical reflection. It was also suggested to have a more differentiated group building strategy in future seminars. A comparison of pre- and post seminar concept maps showed that an increase of factual and conceptual knowledge on the individual level was widely recognizable. Also the evaluation of the case studies (the major seminar output) revealed that the students have undergone developments of both the factual and the conceptual knowledge domain. Also their self-assessment with respect to individual learning development showed that the highest consensus was achieved in the field of subject-specific knowledge. The participants were much more doubtful with regard to the progress of generic competences such as analysis, communication and organisation. However, 50% of the participants confirmed that they perceived individual development on all competence areas the survey had asked for. Have the additional four targets been met? Concerning the competences for working in a virtual team it can be concluded that the vast majority was able to use the internet-based tools and to work with them in a target-oriented way. However, there were obvious differences regarding the intensity and activity of participation, both because of external and personal factors. A very positive aspect is the achievement of a high cultural diversity supporting the participants’ intercultural competence. Learning from group members was obviously a success factor for the working groups. Regarding the possibilities for better accessibility of educational opportunities it became clear that a significant number of participants were not able to go abroad during their studies because of financial or personal reasons. They confirmed that the online seminar was to some extent a compensation for not having been abroad for studying. Inter-institutional learning and synergy was achieved in so far that many teachers from different countries contributed with individual lectures. However, those teachers hardly ever followed more than one session. Therefore, the learning effect remained largely within the seminar learning group. Looking back at the research design it can be said that the pedagogical action research cycle was an appropriate and valuable approach allowing for strong interaction between theory and practice. However, some more external evaluation from peers in particular regarding the participants’ products would have been valuable.

WAIS seminar: Application Performance Monitoring and Architecture Discovery with Kieker

Wednesday 23rd April 2014 Speaker(s): Willi Hasselbring Organiser: Leslie Carr Time: 23/04/2014 14:00-15:00 Location: B32/3077 File size: 802Mb Abstract The internal behavior of large-scale software systems cannot be determined on the basis of static (e.g., source code) analysis alone. Kieker provides complementary dynamic analysis capabilities, i.e., monitoring/profiling and analyzing a software system's runtime behavior. Application Performance Monitoring is concerned with continuously observing a software system's performance-specific runtime behavior, including analyses like assessing service level compliance or detecting and diagnosing performance problems. Architecture Discovery is concerned with extracting architectural information from an existing software system, including both structural and behavioral aspects like identifying architectural entities (e.g., components and classes) and their interactions (e.g., local or remote procedure calls). In addition to the Architecture Discovery of Java systems, Kieker supports Architecture Discovery for other platforms, including legacy systems, for instance, inplemented in C#, C++, Visual Basic 6, COBOL or Perl. Thanks to Kieker's extensible architecture it is easy to implement and use custom extensions and plugins. Kieker was designed for continuous monitoring in production systems inducing only a very low overhead, which has been evaluated in extensive benchmark experiments. Please, refer to http://kieker-monitoring.net/ for more information.

Reviewing Member States’ Commitment to the European External Action Service. EPIN Working Paper No. 34, 20 November 2012

Based on interviews with diplomats from a representative cross-section of nine member states and members of the EEAS itself, the research findings of this EPIN Working Paper confirm long-standing traditions and member state perceptions of cooperation with European institutions. The paper also reveals new aspects of the intergovernmental method of foreign policy shaping and making in the European Union; in particular how different national positions can positively or negatively affect the consolidation of the EEAS and the role of the EU as an international actor. As such, the Working Paper makes an original contribution to the existing literature on one of most discussed actors in the European Union’s post-Lisbon architecture in the domain of EU external action.
