Cross-Border Innovation Support Platform for the SMEs: The Case of St. Petersburg Corridor Region

Työssä tutkitaan eri mekanismeja rajojen ylittävään innovaatioiden edistämiseen pienten ja keskisuurten yritysten näkökulmasta. Case ympäristönä on Kaakkois-Suomen ja Luoteis-Venäjän alueeli Pietarin Corridor. Tavoitteena on löytää tarkemmat määritykset ja rajauksetnäille mekanismeille. Teoriassa muodostettiin viitekehys rajojen ylittävälle innovaatioiden edistämismallille. Mallin pohjalta toteutettiinhaastattelututkimus, joka suoritettiin case-ympäristössä. Haastattelujoukko koostui yritysten edustajista, tutkimus-henkilöstöstä sekä julkisista toimijoista. Innovaatiojärjestelmä oli avoin uusille toimintamenetelmille.Menetelmien toteuttamistapa kuitenkin jakoi mielipiteitä. Toimijoiden välille tarvitaan parempaa yhteistyötä ja tämän kautta selkeämpää kommunikointia yritysten suuntaan. Innovaatioiden edistämiseen ehdotetaan Innovation Relay Centre tyyppisen toiminnan laajentamista Corridorin alueelle sekä sen käyttämän teknologioiden välittämismallin sekä kansainvälisen verkoston hyödyntämistä. Edistämisen tukena tulisi käyttää innovaatiotietokanta-työkalua.

Java Specification Request development on a mobile device

Nykyaikaiset Java-teknologiaa sisältävät matkapuhelimet kehittyvät vauhdikkaasti prosessoritehon, muistin määrän sekä uusien käyttöjärjestelmäversioiden tarjoamien ominaisuuksien myötä. Laitteiden näyttöjen koko tulee pysymään pienenä,mutta silti moninaista multimediasisältöä äänen, videon ja kuvan osilta voidaanhuomattavasti parantaa JSR 234:n eli kehittyneen multimedialaajennuksen avulla.Erityisesti edistyneet ääniominaisuudet ovat tervetullut lisä, sillä viime aikojen kehitys matkapuhelimissa on saanut aikaan niiden muuntumisen myös kannettavaksi musiikkisoittimiksi. Diplomityössä JSR 234 -spesifikaation tietty osa kehitettiin ympäristössä, joka koostui Series 60 -ohjelmistoalustankolmannesta versiosta sekä Symbian OS v9.1 käyttöjärjestelmästä. Tuloksena syntynyt Java-rajapinta tarjoaa sovelluskehittäjille yksinkertaisemman lähestymistavan Symbianin efektirajapintaan piilottaen samalla alla olevan käyttöjärjestelmänmonimutkaisuuden. Toteutuksen täytyy olla läpikotaisin testattu, jotta voidaan varmentua sen noudattavan tarkkaan JSR 234 -spesifikaatiota. Työssä on esitelty useita eri testausmenetelmiä tarkoituksena saavuttaa projektissa paras mahdollinen laatu.

Development of a Business Model that Supports Mobile Value-Added Services Market Creation in Emerging Countries

Tutkielman tavoitteena on luoda liiketoimintamalli, joka tukee langattomien matkaviestintäpalveluiden markkinoiden luomista kehittyvillä markkinoilla. Teoreettinen osa tarkastelee langattomien matkaviestintäpalveluiden liiketoimintamallin kehittämisen tärkeimpiä elementtejä CIS maissa. Teoreettisen kappaleen tuloksena saadaan puitteet, jonka avulla liiketoimintamalli matkaviestintäpalveluille voidaan kehittää. Tutkielman empiirinen osa on toteutettu case tutkimuksena, jonka tavoitteena on ollut langattomien matkaviestintäpalvelujen markkinoiden luominen CIS maissa. Pääasiallinen empiirisen tiedon lähde on ollut teemahaastattelut. Tuloksena saatuja empiirisen osan tietoja verrataan teoriakappaleen vastaaviin tuloksiin Tulokset osoittavat, että radikaalin korkean teknologian innovaation markkinoiden luominen on hidas prosessi, joka vaatii kärsivällisyyttä yritykseltä. Markkinoiden, teknologian ja strategian epävarmuustekijät tuovat epävarmuutta kehittyvälle toimialalle ja markkinoille, joka vaikeuttaa liiketoimintamallin kehittämistä. Tärkein tekijä on palvelujen markkinointi ennemmin kuin teknologian. Avain kyvykkyys markkinoiden luomisessa on oppiminen, ei tietäminen.

Facilitating coordination improvement efforts in cross-functional process development programs

Business process improvement is a common approach in increasing the effectiveness of an organization. It can be seen as an effort to increase coordination between units. Process improvement has proved to be challenging, and most management consultation firms facilitate organizations in this kind of initiatives. Cross-functional improvement is one of the main areas for internal consultants as well. However, the needs, challenges and means of cross-functional help have been rarely discussed in the literature. The objective of this thesis is on one hand to present a conceptual and descriptive framework to help understand the challenges of facilitating coordination improvement efforts in cross-functional improvement programs, and on the other hand to develop and test feasible solutions for some facilitation situations. The research questions are: 1. Why and in what kind of situations do organizations need help in developing coordination in cross-functional processes? 2. How can a facilitator help organizations in improving coordination to develop cross-functional processes? The study consists of two parts. The first part is an overview of the dissertation, and the second part comprises six research publications. The theoretical background for the study are the differentiation causing challenges in cross-functional settings, the coordination needed to improve processes, change management principles, methods and tools, and consultation practises. Three of the publications introduce tools for helping in developing prerequisites, planning responsibilities and supporting learning during the cross-functional program. The three other papers present frameworks to help understand and analyse the improvement situation. The main methodological approaches used in this study are design science research, action research and case research. The research data has been collected from ten cases representing different kinds of organizations, processes and developing situations. The data has been collected mainly by observation, semi-structured interviews and questionnaires. The research contributes to the rare literature combining coordination theories and process improvement practises. It also provides additional understanding of a holistic point of view in process improvement situations. The most important contribution is the addition to the theories of facilitating change in process improvement situations. From the managerial point of view, this study gives advice to managers and consultants in planning and executing cross-functional programs. The main factors increasing the need for facilitation are the challenges for differentiation, challenges of organizational change in general, and the novelty of initiatives and improvement practices concerning process development. Organizations need help in creating the prerequisites to change, in planning initiatives, easing conflict management and collaboration between groups, as well as supporting the learning of cross-functional improvement. The main challenges of facilitation are combining the different roles as a consultant, maintaining the ownership for the improvement project with the client, and supporting learning in the client organization.

Design and development of the architecture of an agricultural mobile robot

Parameters such as tolerance, scale and agility utilized in data sampling for using in Precision Agriculture required an expressive number of researches and development of techniques and instruments for automation. It is highlighted the employment of methodologies in remote sensing used in coupled to a Geographic Information System (GIS), adapted or developed for agricultural use. Aiming this, the application of Agricultural Mobile Robots is a strong tendency, mainly in the European Union, the USA and Japan. In Brazil, researches are necessary for the development of robotics platforms, serving as a basis for semi-autonomous and autonomous navigation systems. The aim of this work is to describe the project of an experimental platform for data acquisition in field for the study of the spatial variability and development of agricultural robotics technologies to operate in agricultural environments. The proposal is based on a systematization of scientific work to choose the design parameters utilized for the construction of the model. The kinematic study of the mechanical structure was made by the virtual prototyping process, based on modeling and simulating of the tension applied in frame, using the.

A Model-Based Development and Verification Framework for Distributed System-on-Chip Architecture

The capabilities and thus, design complexity of VLSI-based embedded systems have increased tremendously in recent years, riding the wave of Moore’s law. The time-to-market requirements are also shrinking, imposing challenges to the designers, which in turn, seek to adopt new design methods to increase their productivity. As an answer to these new pressures, modern day systems have moved towards on-chip multiprocessing technologies. New architectures have emerged in on-chip multiprocessing in order to utilize the tremendous advances of fabrication technology. Platform-based design is a possible solution in addressing these challenges. The principle behind the approach is to separate the functionality of an application from the organization and communication architecture of hardware platform at several levels of abstraction. The existing design methodologies pertaining to platform-based design approach don’t provide full automation at every level of the design processes, and sometimes, the co-design of platform-based systems lead to sub-optimal systems. In addition, the design productivity gap in multiprocessor systems remain a key challenge due to existing design methodologies. This thesis addresses the aforementioned challenges and discusses the creation of a development framework for a platform-based system design, in the context of the SegBus platform - a distributed communication architecture. This research aims to provide automated procedures for platform design and application mapping. Structural verification support is also featured thus ensuring correct-by-design platforms. The solution is based on a model-based process. Both the platform and the application are modeled using the Unified Modeling Language. This thesis develops a Domain Specific Language to support platform modeling based on a corresponding UML profile. Object Constraint Language constraints are used to support structurally correct platform construction. An emulator is thus introduced to allow as much as possible accurate performance estimation of the solution, at high abstraction levels. VHDL code is automatically generated, in the form of “snippets” to be employed in the arbiter modules of the platform, as required by the application. The resulting framework is applied in building an actual design solution for an MP3 stereo audio decoder application.

The early activities of front end of innovation in oem companies using a new fei platform as a framework for renewal

The main goal of this study is to create a seamless chain of actions and more detailed structure to the front end of innovation to be able to increase the front end performance and finally to influence the renewal of companies. The main goal is achieved through by the new concept of an integrated model of early activities of FEI leading to a discovery of new elements of opportunities and the identification of new business and growth areas. The procedure offers one possible solution to a dynamic strategy formation process in innovation development cycle. In this study the front end of innovation is positioned between a strategy reviews and a concept creation with needed procedures, tools, and frameworks. The starting point of the study is that the origins of innovation are not well enough understood. The study focuses attention on the early activities of FEI. These first activities are conceptualized in order to find out successful innovation initiatives and strategic renewal agendas. A seamless chain of activities resulting in faster and more precise identification of opportunities and growth areas available on markets and inside companies is needed. Three case studies were conducted in order to study company views on available theory doctrine and to identify the first practical experiences and procedures in the beginning of the front end of innovation. Successful innovation requires focus on renewal in both internal and external directions and they should be carefully balanced for best results. Instead of inside-out mode of actions the studied companies have a strong outside-in thinking mode and they mainly co-develop their innovation initiatives in close proximity with customers i.e. successful companies are an integral part of customers business and success. Companies have tailor-made innovation processes combined their way of working linked to their business goals, and priorities of actual needs of transformation. The result of this study is a new modular FEI platform which can be configured by companies against their actual business needs and drivers. This platform includes new elements of FEI documenting an architecture presenting how the system components work together. The system is a conceptual approach from theories of emergent strategy formation, opportunity identification and creation, interpretation-analysis-experimentation triad and the present FEI theories. The platform includes new features compared to actual models of FEI. It allows managers to better understand the importance of FEI in the whole innovation development stage and FEI as a phase and procedure to discover and implement emergent strategy. An adaptable company rethinks and redirects strategy proactively from time to time. Different parts of the business model are changed to remove identified obstacles for growth and renewal which gives them avenues to find right reforms for renewal.

A SOA-based Framework for Multi-Devices and Multi-Platform User Interfaces

This thesis reports investigations on applying the Service Oriented Architecture (SOA) approach in the engineering of multi-platform and multi-devices user interfaces. This study has three goals: (1) analyze the present frameworks for developing multi-platform and multi-devices applications, (2) extend the principles of SOA for implementing a multi-platform and multi-devices architectural framework (SOA-MDUI), (3) applying and validating the proposed framework in the context of a specific application. One of the problems addressed in this ongoing research is the large amount of combinations for possible implementations of applications on different types of devices. Usually it is necessary to take into account the operating system (OS), user interface (UI) including the appearance, programming language (PL) and architectural style (AS). Our proposed approach extended the principles of SOA using patterns-oriented design and model-driven engineering approaches. Synthesizing the present work done in these domains, this research built and tested an engineering framework linking Model-driven Architecture (MDA) and SOA approaches to developing of UI. This study advances general understanding of engineering, deploying and managing multi-platform and multi-devices user interfaces as a service.

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.

Energy Consumption of Applications on Mobile Phones

Battery consumption in mobile applications development is a very important aspect and has to be considered by all the developers in their applications. This study will present an analysis of different relevant concepts and parameters that may have impact on energy consumption of Windows Phone applications. This operating system was chosen because there is limited research even though there are related studies for Android an iOS operating systems. Furthermore, another reason is the increasing number of Windows Phone users. The objective of this research is to categorise the energy consumption parameters (e.g. use of one thread or several thread for the same output). The result for each group of experiment will be analyzed and a rule will be derived. The set of derived rules will serve as a guide for developers who intend to develop energy efficient Windows Phone applications. For each experiment, one application is created for each concept and the results are presented in two ways: a table and a chart. The table presents the duration of the experiment, the battery consumed by the experiment, the expected battery lifetime and the energy consumption, while the charts display the energy distribution based on the main threads: UI thread, application thread and network thread.

Phospha-adamantane ligands and phosphorous ionic liquids for palladium-catalyzed cross-coupling reactions /

New and robust methodologies have been designed for palladiumcatalyzed cross-coupling reactions involving a library of novel tertiary phosphine ligands incorporating a phospha-adamantane framework. The secondary phosphine, l,3,5,7-tetramethyl-2,4,8-trioxa-6-phospha-adamantane was converted into a small library of tertiary phosphine derivatives and the ability of these tertiary phosphaadamantanes to act as effective ligands in the palladium-catalyzed amination reaction and p-alkyl-Suzuki cross-coupling was examined. l,3,5,7-Tetramethyl-6- phenyl-2,4,8-trioxa-6-phosphaadamantane (PA-Ph) used in combination with Pd2(dba)3 CHCI3 facilitated the reaction of an array of aryl iodides, bromides and chlorides with a variety secondary and primary amines to give tertiary and secondary amines respectively in good to excellent yields. 8-(2,4-Dimethoxyphenyl)- l,3,5,7-tetramethyl-2,4,6-trioxa-8-phospha-tricyclo[3.3.1.1*3,7*]decane used in combination with Pd(0Ac)2 permitted the reaction of an array of alkyl iodides, and bromides with a variety aryl boronic acids and alkyl 9-BBN compounds in good to excellent yields. Subsequent to this work, the use of phosphorous based ionic liquids, specifically tetradecyltrihexylphosphonium chloride (THPC), in the Heck reaction provided good to excellent yields in the coupling of aryl iodides and bromides with a variety of olefins.
