Tämän diplomityön tarkoitus on rakentaa mobiilipeliyritykselle tuotekehitysprosessin alkupään prosessi tuotekehityksen tehostamiseksi. Toimialan dynaamisuudesta ja hyperkilpailullisuudesta johtuen sekä projektien abstraktin luonteen takia tulee mobiilipelikehitysyritysten erityisesti panostaa tuotekehityksen alkuvaiheisiin. Työ tutkii yleisiä tuotekehityksen periaatteita sekä yleisiä olemassaolevia tuotekehitysprosesseja. Tarkastelun kohteena ovat erityisesti innovatiivinen organisaatio ja benchmarking tuotekehityksen apuna. Yleisesti tuotekehitysprosesseista tutustutaan yleisimpiin malleihin, jotka ovat olleet valtavirran käytössä jo pitkään. Prosessien tarkastelun lisäksi niitä tutkitaan kriittisesti ja löydetään osa-alueita, joihin tulee keskittyä erityisesti tuotekehitysprosessin alkupään järjestämisessä. Lisäksi työssä paneudutaan alan menestyneiden yritysten toimintatapoihin, joista haetaan oppia rakennettavaan malliin. Työssä käsitellään myös toimialan ominaispiirteitä, joista johtuen perinteiset tuotekehitysprosessit eivät ole optimaalisia alalle. Työn tuloksena saadaan virtaviivainen prosessimalli, joka maksimoi luovuuden, mutta säästää resursseja ja luo selkeät linjat prosessin läpivientiin. Rakennettuun malliin pohditaan myös kehitysehdotuksia, ja sille on laadittu kevyt jatkokehityssuunnitelma. Malli menee suoraan yrityksen käyttöön, joten lopullinen malli tulee myös hioutumaan tuotekehitysprojektien edetessä. Työssä on erityistä se, että työn tekijä on toiminut alalla työtehtävissä, ja malli on hioutunut pitkän ajan kuluessa. Täten suuri osa työstä on tekijän hiljaisen tiedon avaamista ja pohtimista.

Many-core systems are emerging from the need of more computational power and power efficiency. However there are many issues which still revolve around the many-core systems. These systems need specialized software before they can be fully utilized and the hardware itself may differ from the conventional computational systems. To gain efficiency from many-core system, programs need to be parallelized. In many-core systems the cores are small and less powerful than cores used in traditional computing, so running a conventional program is not an efficient option. Also in Network-on-Chip based processors the network might get congested and the cores might work at different speeds. In this thesis is, a dynamic load balancing method is proposed and tested on Intel 48-core Single-Chip Cloud Computer by parallelizing a fault simulator. The maximum speedup is difficult to obtain due to severe bottlenecks in the system. In order to exploit all the available parallelism of the Single-Chip Cloud Computer, a runtime approach capable of dynamically balancing the load during the fault simulation process is used. The proposed dynamic fault simulation approach on the Single-Chip Cloud Computer shows up to 45X speedup compared to a serial fault simulation approach. Many-core systems can draw enormous amounts of power, and if this power is not controlled properly, the system might get damaged. One way to manage power is to set power budget for the system. But if this power is drawn by just few cores of the many, these few cores get extremely hot and might get damaged. Due to increase in power density multiple thermal sensors are deployed on the chip area to provide realtime temperature feedback for thermal management techniques. Thermal sensor accuracy is extremely prone to intra-die process variation and aging phenomena. These factors lead to a situation where thermal sensor values drift from the nominal values. This necessitates efficient calibration techniques to be applied before the sensor values are used. In addition, in modern many-core systems cores have support for dynamic voltage and frequency scaling. Thermal sensors located on cores are sensitive to the core's current voltage level, meaning that dedicated calibration is needed for each voltage level. In this thesis a general-purpose software-based auto-calibration approach is also proposed for thermal sensors to calibrate thermal sensors on different range of voltages.

This study investigates the development of relationships in same global virtual team working on different projects. The purpose is to explore how do interpersonal relationships develop in terms of characteristics of virtuality and if there is any influence of project lifespan on the development of these relationships. Since relationships are dynamic in nature and are influenced by multiple levels of variables including individual, group and organizational level, therefore characteristics of virtuality have been considered from all these aspects so as to study their influence on development of relationships. In this study, relationships have been studied at two different levels. At first, dyadic relationships between two members of a GVT have been analyzed and thereafter, focus has been on the development of relationships among the team, based on these dyads. Characteristics having influence on development of relationships include trust, physical distance, time zone difference, cultural and language differences, level of formalization in the organization and means of communication used by team members. Level of formalization and means of communication are two characteristics which emerged after empirical study and are found to have direct influence on development of relationships. Remaining characteristics have been identified through literature review. In order to conduct the study, qualitative methodology has been applied. Empirical data has been collected based on a single case study while using semi-structured interviews as data gathering technique. Data analysis has been performed by applying thematic analysis along with the utilization of company documents such as work sheets, minutes of meetings and recordings of conferences. Findings of the study indicate that development of relationships, both at dyadic level and team level, is influenced by different events taking place among different members of GVT. These events have either positive or negative influence on the characteristics of virtuality, which leads to development of the relationships. It has been found that, trust, among all factors plays a greater role in development of these relations. Contrary to the belief that most conflicts arise among members of different cultures, they are equally likely to happen among the members from same culture in GVT environment. Study suggests that relationship development is not a smooth process but it fluctuates based on different events in teams. For further research, teams within large firms shall be studied along these lines. This study is an early attempt towards bringing different characteristics of virtuality together which previously, have been studied individually. It is therefore plausible to conduct similar studies so as to generalize the findings of this study which has provided a starting point.

Työn kohteena olivat Suomen öljytaseeseen liittyvät kansainväliset vuosikyselyt, joiden raportoinnista Suomessa vastaa Tilastokeskus. Samalla tarkasteltiin Tilastokeskuksen laatimia kansallisia energiatilastoja, jotka liittyvät öljyn hankintaan, jalostukseen ja käyttöön. Työn pääpaino oli kuitenkin kansainvälisissä raportoinneissa. Työn tavoitteena oli kehittää Eurostatin, IEA:n ja YK:n vuosittaisen öljykyselyn sekä YK:n ilmastosopimukselle laadittavaan kasvihuonekaasuinventaarioon liittyvän Reference Approach -laskennan raportointia. Selvitysten toivottiin pienentävän öljynhankinnan ja kulutuksen välisistä tase-eroista johtuvia tilastovirheitä. Kansainvälisten raportointien tutkimuksesta odotettiin myös löytyvän kehittämisehdotuksia kansallisiin energiatilastoihin. Vuosittaisten energiakyselyiden pohjalta syntyvät merkittävimmät kansainväliset energiatilastotietokannat. Tietoja käytetään useisiin tarkoituksiin muun muassa energian riittävyyden jakulutuksen analysointiin globaalisti. Reference Approach on taas vaihtoehtoinenlaskentatapa energiakäytöstä ja -tuotannosta aiheutuville hiilidioksidipäästöille. Reference Approach raportoidaan vuosittain YK:n ilmastosopimukselle. Työ toteutettiin tarkastelemalla kansainvälisen öljykyselyn rakennetta ja useista eri lähteistä saatuja öljytuotteiden lähtötietoja. Vuoden 2004 öljykyselyä täydennettiin ja tietoja verrattiin alkuperäiseen raporttiin. Reference Approach -laskennan tutkiminen toteutettiin tarkistamalla öljytuotteiden lähtötiedot ja loppukäytön jakaantuminen energiakäytön ja raaka-ainekäytön välillä. Tutkimuksien pohjalta Reference Approach -aikasarja laskettiin uudelleen ja tuloksia verrattiin alkuperäiseen aikasarjaan. Työn tuloksena saatiin sekä kansainvälistä öljykyselyä että Reference Approach -laskentaa tarkennettua huomattavasti. Samalla tilastovirheet pienenivät merkittävästi. Työssä tehtyjä havaintoja ja tuloksia tullaan hyödyntämään jatkossa sekä Suomen kasvihuonekaasupäästöjen laskennassa että kansainvälisen öljykyselyn raportoinnissa.

Diplomityö on tehty Insinööritoimisto W.Zenner Oy:n LVI -tekniikan laboratoriossa. Insinööritoimisto W.Zenner Oy:n LVI-tekniikan laboratorio tarjoaa alan yrityksille tutkimuspalveluita sekä laboratoriossa että kentällä. Tämän työn tarkoituksena on ollut määrittää asiakkaan keksimän, toimintaperiaatteltaan aiemmista poikkeavan, lumenerotusjärjestelmän prototyypin lumenerotusaste. Mittausten aikana kuitenkin ilmeni, että keksintö ei sellaisenaan ole toimiva. Tämän vuoksi on työssä käsitelty hieman laajemmin lumenerottelutapoja, järjestelmien suunnittelu- ja käyttöperusteita sekä niiden testausmahdollisuuksia.

Työssä käsitellään Itämeren rahtiliikennettä ja sen kehitykseen vaikuttavia tekijöitä. Työn ajankohtaisuutta on lisännyt Euroopan unionin laajentuminen toukokuussa 2004, jolloin Viro, Latvia, Liettua ja Puola liittyivät kaikki EU:hun. Työn teoriaosuus painottuu tulevaisuudentutkimukseen ja erityisesti skenaariotutkimukseen. Työssä on esitetty kahdenlaisia skenaarioita. Toisissa käsitellä Suomesta ja Ruotsista Baltian maihin suuntautuvaa rahtiliikennettä. Skenaariot on ulottuvat aina vuoteen 2011 asti. Toiset skenaariot puolestaan käsittelevät Suomen ja Puolan välisen rahtiliikenteen tulevaisuutta. Baltian skenaarioissa korostuu Venäjän suuri rooli. Venäjälle suuntautuva transitoliikenne on kaikille Baltian maille hyvin tärkeää. Sen määrän kehitys kuitenkin riippuu hyvin paljon Venäjän omien satamien sekä Venäjän talouden kehityksestä. Venäjän taloudellinen kehitys säätelee myös hyvin paljon ympäristön kehitystä. Baltian liikenteen kehittymistä säätelee myös vahvasti koko Itä-Euroopan sekä Valko-Venäjän ja Ukrainan liikenteen kehitys. Euroopan unionin jäsenyys tuo omat lisänsä kehityksen suunnille erilaisten tukien ja kehitysprojektien mukana. Puolan skenaarioissa korostuu Puolan maantieteellisen sijainnin merkitys keskellä Eurooppaa. Paineet Saksan ruuhkaongelmien purkamisen ja itäisen Euroopan nopean talouskasvun myötä keskittyvät Puolan liikenteeseen. Puolan maaliikenneinfrastruktuuri vaatii suuria kehitysprojekteja, joita rahoittamaan tarvitaan etenkin Euroopan Unionia. Puolan valtion suuri asukaspotentiaali tekee siitä myös erityisen kiinnostavan sijoituskohteen ulkomaisille investoijille. Myös tämä osaltaan lisää Puolan liikennettä. Sekä Puolassa, että Baltiassa eletään vahvan kasvun aikaa. Tämä tekee molemmista mielenkiintoisen vaihtoehdon liikennöintikohteeksi.

The Gulf of Finland is said to be one of the densest operated sea areas in the world. It is a shallow and economically vulnerable sea area with dense passenger and cargo traffic of which petroleum transports have a share of over 50 %. The winter conditions add to the risks of maritime traffic in the Gulf of Finland. It is widely believed that the growth of maritime transportation will continue also in the future. The Gulf of Finland is surrounded by three very different national economies with, different maritime transportation structures. Finland is a country of high GDP/per capita with a diversified economic structure. The number of ports is large and the maritime transportation consists of many types of cargoes: raw materials, industrial products, consumer goods, coal and petroleum products, and the Russian transit traffic of e.g. new cars and consumer goods. Russia is a large country with huge growth potential; in recent years, the expansion of petroleum exports has lead to a strong economic growth, which is also apparent in the growth of maritime transports. Russia has been expanding its port activities in the Gulf of Finland and it is officially aiming to transport its own imports and exports through the Russian ports in the future; now they are being transported to great extend through the Finnish, Estonian and other Baltic ports. Russia has five ports in the Gulf of Finland. Estonia has also experienced fast economic growth, but the growth has been slowing down already during the past couples of years. The size of its economy is small compared to Russia, which means the transported tonnes cannot be very massive. However, relatively large amounts of the Russian petroleum exports have been transported through the Estonian ports. The future of the Russian transit traffic in Estonia looks nevertheless uncertain and it remains to be seen how it will develop and if Estonia is able to find replacing cargoes if the Russian transit traffic will come to an end in the Estonian ports. Estonia’s own import and export consists of forestry products, metals or other raw materials and consumer goods. Estonia has many ports on the shores of the Gulf of Finland, but the port of Tallinn dominates the cargo volumes. In 2007, 263 M tonnes of cargoes were transported in the maritime traffic in the Gulf of Finland, of which the share of petroleum products was 56 %. 23 % of the cargoes were loaded or unloaded in the Finnish ports, 60 % in the Russian ports and 17 % in the Estonian ports. The largest ports were Primorsk (74.2 M tonnes) St. Petersburg (59.5 M tonnes), Tallinn (35.9 M tonnes), Sköldvik (19.8 M tonnes), Vysotsk (16.5 M tonnes) and Helsinki (13.4 M) tonnes. Approximately 53 600 ship calls were made in the ports of the Gulf of Finland. The densest traffic was found in the ports of St. Petersburg (14 651 ship calls), Helsinki (11 727 ship calls) and Tallinn (10 614 ship calls) in 2007. The transportation scenarios are usually based on the assumption that the amount of transports follows the development of the economy, although also other factors influence the development of transportation, e.g. government policy, environmental aspects, and social and behavioural trends. The relationship between the development of transportation and the economy is usually analyzed in terms of the development of GDP and trade. When the GDP grows to a certain level, especially the international transports increase because countries of high GDP produce, consume and thus transport more. An effective transportation system is also a precondition for the economic development. In this study, the following factors were taken into consideration when formulating the future scenarios: maritime transportation in the Gulf of Finland 2007, economic development, development of key industries, development of infrastructure and environmental aspects in relation to maritime transportation. The basic starting points for the three alternative scenarios were: • the slow growth scenario: economic recession • the average growth scenario: economy will recover quickly from current instability • the strong growth scenario: the most optimistic views on development will realize According to the slow growth scenario, the total tonnes for the maritime transportation in the Gulf of Finland would be 322.4 M tonnes in 2015, which would mean a growth of 23 % compared to 2007. In the average growth scenario, the total tonnes were estimated to be 431.6 M tonnes – a growth of 64 %, and in the strong growth scenario 507.2 M tonnes – a growth of 93%. These tonnes were further divided into petroleum products and other cargoes by country, into export, import and domestic traffic by country, and between the ports. For petroleum products, the share of crude oil and oil products was estimated and the number of tanker calls in 2015 was calculated for each scenario. However, the future development of maritime transportation in the GoF is dependent on so many societal and economic variables that it is not realistic to predict one exact point estimate value for the cargo tonnes for a certain scenario. Plenty of uncertainty is related both to the degree in which the scenario will come true as well as to the cause-effect relations between the different variables. For these reasons, probability distributions for each scenario were formulated by an expert group. As a result, a range for the total tonnes of each scenario was formulated and they are as follows: the slow growth scenario: 280.8 – 363 M tonnes (expectation value 322.4 M tonnes)

  • the average growth scenario: 404.1 – 465.1 M tonnes (expectation value 431.6 M tonnes)
  • the strong growth scenario: 445.4 – 575.4 M tonnes (expectation value 507.2 M tonnes) Three alternatives scenarios were evaluated to realize most likely with the following probability distribution:
  • the slow growth scenario: 35 %
  • the average growth scenario: 50 %
  • the strong growth scenario: 15 %. In other words, expert group evaluated the average growth scenario to be the most likely to realize, second likely was the slow growth scenario, and the strong growth scenario was evaluated to be the most unlikely to realize. In sum, it can be stated that the development of maritime transportation in the Gulf of Finland is dominated by the development of Russia, because Russia dominates the cargo volumes. Maritime transportation in Finland is expected to be more stable and, in any case, such a growth potential cannot be seen in Finland. The development of maritime transportation in Estonia is rather challenging to forecast at the moment but, on the other hand, the transported tonnes in the Estonian ports are relatively small. The shares of export and import of the maritime transportation are not expected to change radically in the reference period. Petroleum products will dominate the transports also in the future and the share of oil products will probably increase compared to the share of crude oil. In regard to the other cargoes, the transports of raw materials and bulk goods will probably be replaced to some extend by cargoes of high-value, which adds especially to the container transports. But in overall, substantial changes are not expected in the commodity groups transported by sea. The growth potential of the ports concentrates on the Russian ports, especially Primorsk and Ust-Luga, if investments will come true as planned. It is likely that the larger ports do better in the competition than the small ones due to the economies of scale and to the concentration of cargo flows. The average ship sizes will probably grow, but the growth potential is rather limited because of geographical conditions and of the maritime transportation structure in the Gulf of Finland. Climate change and other environmental aspects are becoming more central e.g. in transportation politics. These issues can affect the maritime transportation in the Gulf of Finland through, for instance, strict environmental requirements concerning the emissions from shipping, or the port investments. If environmental requirements raise costs, it can affect the demand of transportation. In the near future, the development of the maritime transportation in the Gulf of Finland is mainly dependent on the current economic instability. If it will lead to a longer lasting recession, the growth of the transported tonnes will slow down. But if the instability does not last long, it can be expected that the economic growth will continue and along with it also the growth of transported tonnes.

    Traditionally mostly publicly provided Finnish healthcare services are confronted today by the evident challenge of rising healthcare costs as the expenditure on health and social case has exceeded Finland’s national GDP growth significantly since the new millennium. While the opening of the traditional barriers through the EU’s new patient directive resulting in increasing international competition and the free flow of patients within the EU present opportunities for the Finnish healthcare services industry there are also several challenges for the existing healthcare system as proposed by the Ministry of Employment and the Economy in 2011. Due to the structure and nature of the current Finnish healthcare service system the greatest potential for internationalization is seen from a joint cooperation of the public and private sectors in an internationalization network for Finnish healthcare services. As its formation has recently also taken as a strategic initiative to be completed by the Ministry of Employment and the Economy and no earlier research exists on how this is seen in practice by the network actors, the purpose of this study is to examine the proposed solution of forming an internationalization network between the public and private sector actors in Finland in practice from the viewpoint of public sector actors. The research relied heavily on the reports by the Finnish Ministries in understanding the current situation of the Finnish healthcare services internationalization and its potential. Suitable theories were also used to build a more comprehensive view of the matter. The study applied a qualitative research approach on the explorative research problem. The data collection was achieved through expert interviews in two of the largest Finnish public healthcare service providers; the Turku and Helsinki Central University Hospitals. Expert interviews were considered as the most suitable method for data collection in order to create an in-depth understanding of the topic within the limitations of this thesis. In turn, two different public healthcare service providers were chosen to give a broader view of the field instead of focusing on a specific unit and also to allow a possible comparison between the two different organizations. The latter however was shown not to be suitable for the purposes of this study as the opinions of the respondents varied largely also within their own organizations. The conclusion is that while the actors agree on the evident internationalization of Finnish healthcare services, there are several large-scale structural challenges effectively preventing such activities while at the same time the opportunities within Finland vary, as there are several niches but no real large-scale advantages in the highly competitive industry. Interest towards cooperation between the sectors are seen especially in exploiting the advantages offered by the private sector in commercialization and marketization, yet however no clear views exist on how these activities should be governed or structured in the short-term as a larger reform of the entire Finnish healthcare service sector is needed in the long-term.
