ABSTRACT The main aim of this paper was to contribute to reflections in Brazil on the need to transfer knowledge held at universities and R&D institutions over to companies, i.e. to transfer scientific knowledge of chemistry to technology. It discusses how the competitiveness of countries is increasingly dependent on their technological capacity. The chemicals industry is a fundamental driver of social, environmental, economic and industrial indicators of sustainable development. In Brazil, the chemicals industry's deficit has grown over the last three decades. Patents are important sources of information because patent documents contain 75% of all technological information available. The National Institute of Industrial Property in Brazil has created a Technology Observatory with the purpose of identifying and analyzing technological information contained in patent documents within the ambit of partnerships with government entities or business associations, in order to support their technology-related decision-making processes. The paper gives examples of ethanol and biotechnology patent documents, including pharmaceuticals, of which there are very few in Brazil. However, a few of the patent applications identified are filed in Brazil, giving the country the opportunity to transform this scientific knowledge into technology by means of partnership agreements with companies. Finally, the paper presents information on the patent applications filed by the world's leading chemicals companies as measured by their revenues, and the respective numbers of patent applications in the last five years in organic chemistry and polymers, sectors in which Brazil is currently dependent on imports for over 50% of its needs. The patent assignees in these sectors in Brazil are also identified, and the paper concludes that Brazil needs to invest in the development of professionals, providing clearly-defined career paths in technology innovation teams at R&D institutions, and to foster more initiatives such as the creation of a new research and innovation entity, EMBRAPII, since investing in science and technology is a prerequisite for knowledge production, industrial property, economic development and, consequently, the competitiveness of the country.

XML-muotoista tiedonesitystapaa hyödynnetään yhä enemmän esitettäessä rakenteellista tietoa. Tarkoituksena on antaa yleishyödyllinen ja uudelleenkäytettävä tapa jakaa yleistä tietoa erilaisten rajapintojen yli. XML-tekniikoita käytetään myös korjaamaan aiemmin tehdyissä sovellutuksissa esiintyneitä puutteita ja parantamaan niiden toimintaa. Tässä diplomityössä esitellään Telestelle LabView-pohjaiseen testaussovellusympäristöön suunniteltava ajuriuudistus. Työssä paranneltiin aiempaa ajurimallia soveltamalla siihen XML-tekniikoita hyödyntäviä toimintoja. Tarkoituksena oli vähentää testaussovelluskehityksessä vaadittavaa ohjelmointityötä korvaamalla sovelluksiin kovakoodatut ominaisuudet XML-pohjaisilla konfiguraatiotiedostoilla. Järjestelmän pohjana on yleiskäyttöinen ajuri, joka käyttää Telesten omaa EMS-protokollaa kommunikoinnissaan testattavien tuotteiden kanssa. Ajurimalli käyttää XML-pohjaisia konfiguraatiotiedostoja määrittelemään testattavien tuotteiden ominaisuuksia. XML-skeematiedostoilla esitetään ajurin käyttämän kommunikaatioprotokollan viestityypit ja niiden rakenteet. Työn tuloksena onnistuttiin luomaan uudenlainen XML-tekniikoita hyödyntävä ajurimalli. Yhteen yhteiseen ajuriin perustuva malli yhdenmukaistaa testaussovelluksien toteuttamista ja vähentää tarvittavaa ohjelmointityötä. Ajurin käyttöä helpotettiin toteuttamalla testaussovelluksien kehitysympäristöön erityinen editori, jolla voidaan helposti luoda ajuria käyttäviä toimintoja.

The profitability on transportation field has been low for a long time. The re-cession that started in the fall of 2008 has caused even more trouble to transportation companies as the number of transportations has gone down and the competition has gotten tougher since the time before the recession. Because the low profitability level does not allow competing with prices, transportation companies must come up with other means to differ from their competitors. The main goal of the research was to find out how a small and medium-sized enterprise (SME) on transportation field should manage its customer relationships. Due to limited resources, companies should direct their resources to serving their most valuable customers. Companies should first make a determination of their customer base. This works as a base for establishing customer portfolios, in other words making customer groups based on e.g. profitability, buying volumes and loyalty. Companies can gain competitive advantage also by improving their service quality. Important information regarding the selection criteria of a transporta-tion company, transaction methods, service time and accessibility of person-nel, customers’ expectations on transportation company’s personnel, utiliza-tion of IT-solutions as a part of transportation service, the image of a transportation company and necessity of quality control meetings was gathered for this research by interviewing customers. By utilizing this information, transportation company can adapt its service offering to equal the customer needs and expectations better. A service process example was created to improve the service quality of the transportation company. It shows the whole process from the customer sending the transportation order to the point when the customer receives an invoice from the transportation company. The example process shows the most fragile stages of the service process: the interaction points. An example of this is when the driver and the customer meet at the unloading place. The results show that even a SME can have the opportunity to succeed in competitive markets by managing CRM. Expensive software are usually out of reach of a SME, but having a CRM software does not automatically guar-antee success in customer relationship management. Small and medium-sized firms can commit their current customers and recruit new customers by utilizing customer knowledge, offering top quality service, being innovative and offering functional services.

Työn tavoitteena oli tutkia Etelä-Karjalan sosiaali- ja terveydenhuollon kuntayhtymän kuntalaskutusta ja rakentaa laskentamalli, jolla kuntakohtaiset kustannukset pystytään laskemaan ja jakamaan. Tutkimusote oli konstruktiivinen. Tiedot kerättiin kuntayhtymän toiminta- ja taloustietojärjestelmistä sekä haastattelemalla organisaation asiantuntijoita. Työn tulokseksi saatu laskentamalli koostuu suoritepohjaisesta, asukaslukupohjaisista ja tarvepainotetuista asukaslukupohjaisista kustannusajureista, joilla kustannukset jaetaan piirin jäsenkunnille. Tällä sekamallilla pystytään toteuttamaan kuntalaskutusta, sillä se täyttää kuntalaskutusmallille asetetut vaatimukset. Työn tulosten perusteella tulo-osuusmalli olisi paras tapa toteuttaa kuntalaskutusta. Yksinkertainen rahoitusmalli mahdollistaa toiminnan vapaamman kehittämisen kuin sekamalli ja on lisäksi selkeämpi ja läpinäkyvämpi. Sekamallissa tulisi painottaa tarvepohjaisia asukaslukuajureita. Tärkeimmät ja suurimpia kustannuksia aiheuttavat alueet kannattaisi tuotteistaa.

Innovation has been widely recognized as an important driver of firm competitiveness, and the firm’s internal research and development (R&D) activities are often considered to have a critical role in innovation activities. Internal R&D is, however, not the source of innovation as firms may tap into knowledge necessary for innovation also through various types of sourcing agreements or by collaborating with other organizations. The objective of this study is to analyze the way firms go about organizing efficiently their innovation boundaries. Within this context, the analysis is focused, firstly, on the relation between innovation boundaries and firm innovation performance and, secondly, on the factors explaining innovation boundary organization. The innovation literature recognizes that the sources of innovation depend on the nature of technology but does not offer a sufficient tool for analyzing innovation boundary options and their efficiency. Thus, this study suggests incorporating insights from transaction cost economics (TCE) complemented with dynamic governance costs and benefits into the analysis. The thesis consists of two parts. The first part introduces the background of the study, research objectives, an overview of the empirical studies, and the general conclusions of the study. The second part is formed of five publications. The overall results firstly indicate that although the relation between firm innovation boundary options is partly industry sector-specific, the firm level search strategies and knowledge transfer capabilities are important for innovation performance independently of the sector. Secondly, the results show that the attributes suggested by TCE alone do not offer a sufficient explanation of innovation boundary selection, especially under conditions of high levels of (radical) uncertainty. Based on the results, the dynamic governance cost and benefit framework complements the static TCE when firm innovation boundaries are scrutinized.

Tämä kandidaatintyö käsittelee subwoofer-kaiuttimen mallinnusta ja analysointia impulssivasteen perusteella. Refleksikoteloidulle kaiuttimelle muodostetaan siirtofunktio ja sen avulla simuloidaan kaiuttimen impulssivasteen käyttäytymistä erilaisilla kotelon virityksillä. Simuloinnit toteutetaan kolmella erilaisella kaiutinelementillä käyttäen kullekin viittä erityyppistä viritystä. Simulointien toimivuutta käytännössä yritetään todistaa mittauksilla, joissa simulointien pohjalta toteutetaan viisi viritystä rakentamalla refleksikotelo Seas P11RCY-kaiutinelementille ja mittaamalla kunkin virityksen tuottama askelvaste. Tämän jälkeen mitatuista askelvasteista määritetään impulssivasteet laskennallisesti ja verrataan niitä toisiinsa sekä simulointien tuloksiin yrittäen löytää mahdollinen korrelaatio simulointien ja mittausten välille. Määritetään myös mikä käytetyistä viidestä virityksestä tuottaa parhaimman vasteen kullekin kolmelle kaiutinelementille.

This thesis considers modeling and analysis of noise and interconnects in onchip communication. Besides transistor count and speed, the capabilities of a modern design are often limited by on-chip communication links. These links typically consist of multiple interconnects that run parallel to each other for long distances between functional or memory blocks. Due to the scaling of technology, the interconnects have considerable electrical parasitics that affect their performance, power dissipation and signal integrity. Furthermore, because of electromagnetic coupling, the interconnects in the link need to be considered as an interacting group instead of as isolated signal paths. There is a need for accurate and computationally effective models in the early stages of the chip design process to assess or optimize issues affecting these interconnects. For this purpose, a set of analytical models is developed for on-chip data links in this thesis. First, a model is proposed for modeling crosstalk and intersymbol interference. The model takes into account the effects of inductance, initial states and bit sequences. Intersymbol interference is shown to affect crosstalk voltage and propagation delay depending on bus throughput and the amount of inductance. Next, a model is proposed for the switching current of a coupled bus. The model is combined with an existing model to evaluate power supply noise. The model is then applied to reduce both functional crosstalk and power supply noise caused by a bus as a trade-off with time. The proposed reduction method is shown to be effective in reducing long-range crosstalk noise. The effects of process variation on encoded signaling are then modeled. In encoded signaling, the input signals to a bus are encoded using additional signaling circuitry. The proposed model includes variation in both the signaling circuitry and in the wires to calculate the total delay variation of a bus. The model is applied to study level-encoded dual-rail and 1-of-4 signaling. In addition to regular voltage-mode and encoded voltage-mode signaling, current-mode signaling is a promising technique for global communication. A model for energy dissipation in RLC current-mode signaling is proposed in the thesis. The energy is derived separately for the driver, wire and receiver termination.

The air included in droplets generated by spray nozzles directly int0erferes in transport, deposition and retention of the droplets after its impact on the target. The objective of this study was to analyze the interference of adjuvants in the amount of air included in droplets generated by spray nozzles. The treatments were composed by four spray solutions containing mineral oil, vegetable oil, surfactant and water, and three spray nozzles, two air induction type and one pre-orifice. The air included was calculated by the difference between the volume of spray mix (air plus liquid) and only the liquid, which was made by means of sprayed samples captured in a funnel and collected in a graduated cylinder. The surface tension was estimated by the gravimetric method using a precision scale and a graduated pipette. The surfactant provided the largest percentage of air included in the spray. For the surface tension, the mineral oil and the surfactant had the lowest values. It was concluded that the use of adjuvants had a direct influence on the percentage of air included. In addition, products with greater ability to reduce surface tension and to form homogeneous solutions provided the increase in the percentage of air included in the droplet.

ABSTRACT The present study aims to present the main concepts of the sugarcane straw to energy planning. Throughout the study, the subject is contextualized highlighting broader aspects of sustainability, which is considered the main driver towards agro-energy modernization. Concerning sugarcane straw, we first evaluated its availability regarding technical and economic aspects, and then it summarized the straw production chain for energy supply purposes. As a proposal to support agro-energy planning, it is presented some spatial tools that have been barely used in the Brazilian energy planning context so far. Therefore, working on straw to electricity associated with supply chain basis, we developed a conceptual model to spatially assess this bioenergy system. Using the model proposed, it is described the whole supply chain at state level, which accounted the potential of a single mill to explore straw, as well as main costs associated with straw acquisition, investments on the straw recovery routes and electricity transmission. Bearing these concepts in mind, it is fully believed that spatial analysis can bring important information for agro-energy action plans.

Companies operating in today’s highly internationalized markets consider product differentiation the key priority in pursue to attain a constant competitive advantage in challenging global environment (Baker and Ballington 2002, 158). The main driver affecting companies’ differentiation actions was described as early as 1912 by one of the marketing pioneers A. W. Shaw (1912, 710) as meeting human wants more accurate than the competition, and thus increasing customers’ perceived value and satisfaction. Dickson and Ginter (1987, 2) point out in their study based on earlier research by Chamberlin (1965) and Porter (1976) that differentiation can be based on either tangible characteristics of a product such as design or intangible characteristics such as a brand name and country of origin (hereafter referred to as COO). The concept of COO and its impact on consumers’ evaluation of a product as an extrinsic product cue has been one of the most noteworthy topics in international marketing, having been voluminously examined by over 780 authors in more than 750 academic publications in the past 40 years (Papadopoulos and Heslop 2002, 294). Many of these studies accentuate the significant effect the COO has on consumers’ product attribute evaluations. People routinely associate country images with products and services in order to judge and categorize them based on perceived quality and risk levels; thereby COO can influence the likelihood of a purchase (Peterson and Jolibert 1995, 883-884; Verlegh and Steenkamp 1999, 523). Based on the vast research related to COO in the field of international business, it is widely recognized that the country associated with a product can act in a similar way as the name of a brand and even become a part of product’s total image. Thereby depending on customer’s values and perceptions, the product-country image can either increase or decrease perceived value.

One of the main developments in the global economy during the past decades has been the growth of emerging economies. Projections for their long-term growth, changes in the investment climate, corporate transparency and demography point to an increasing role for these emerging economies in the global economy. Today, emerging economies are usually considered as financial markets offering opportunities for high returns, good risk diversification and improved return-to-risk ratios. However, researchers have noted that these advantages may be in decline because of the increasing market integration. Nevertheless, it is likely that certain financial markets and specific sectors will remain partially segmented and somewhat insulated from the global economy for the year to come. This doctoral dissertation investigates several stock markets in Emerging Eastern Europe (EEE), including the ones in Russia, Poland, Hungary, the Czech Republic, Bulgaria and Slovenia. The objective is to analyze the returns and financial risks in these emerging markets from international investor’s point of view. This study also examines the segmentation/integration of these financial markets and the possibilities to diversify and hedge financial risk. The dissertation is divided into two parts. The first includes a review of the theoretical background for the articles and a review of the literature on EEE stock markets. It includes an overview of the methodology and research design applied in the analysis and a summary of articles from the second part of this dissertation and their main findings. The second part consists of four research publications. This work contributes to studies on emerging stock markets in four ways. First, it adds to the body of research on the pricing of risk, providing new empirical evidence about partial stock market segmentation in EEE. The results suggest that the aggregate emerging market risk is a relevant driver for stock market returns and that this market risk can be used to price financial instruments and forecast their performance. Second, it contributes to the empirical research on the integration of stock markets, asset prices and exchange rates by identifying the relationships between these markets through volatility and asset pricing. The results show that certain sectors of stock markets in EEE are not as integrated as others. For example, the Polish consumer goods sector, the Hungarian telecommunications sector, and the Czech financial sector are somewhat isolated from their counterparts elsewhere in Europe. Nevertheless, an analysis of the impact of EU accession in 2004 on stock markets suggests that most of the EEE markets are becoming increasingly integrated with the global markets. Third, this thesis complements the scientific literature in the field of shock and volatility spillovers by examining the mechanism of spillover distribution among the EU and EEE countries. The results illustrate that spillovers in emerging markets are mostly from a foreign exchange to the stock markets. Moreover, the results show that the effects of external shocks on stock markets have increased after the enlargement of the EU in 2004. Finally, this study is unique because it analyzes the effects of foreign macroeconomic news on geographically closely related countries. The results suggest that the effects of macroeconomic announcements on volatility are significant and have effect that varies across markets and their sectors. Moreover, the results show that the foreign macroeconomic news releases, somewhat surprisingly, have a greater effect on the EEE markets than the local macroeconomic news. This dissertation has a number of implications for the industry and for practitioners. It analyses financial risk associated with investing in Emerging Eastern Europe. Investors may use this information to construct and optimize investment portfolios. Moreover, this dissertation provides insights for investors and portfolio managers considering asset allocation to protect value or obtain higher returns. The results have also implications for asset pricing and portfolio selection in light of macroeconomic news releases.

The aim of the study is to expand networking between a packaging material manufacturer and retailers in order to develop products which appeal to brand owners and their customers. The in-built targets are to understand the retailer’s role in the value chain, clarify who makes packaging decision of private label products, and canvass the importance of sustainability. The present value chain of the packaging material manufacturer is reviewed first. It is assumed that sustainability could be a common interest, and The Consumer Goods Forum’s “A Global Language for Packaging and Sustainability” report is shortly discussed. The presentation of the most common packaging materials is based on a guide called “Packaging in the Sustainability Agenda: A Guide for Corporate Decision Makers”. The terms manufacturer’s brand and private label are defined. A retail value chain with emphasis on the role of customers as partners is introduced. The study area is the Nordic countries, and the information about Nordic retailers was provided first by desk research. The interviews were made in Finland, Sweden, Norway and Denmark. The study method is qualitative: the intention was to get initial insights, ideas and understandings. The results are compiled under the headings: sustainability, private labels, cooperation and packaging development. Also the reasons for good profitability of private labels are explained. Sustainability or responsibility is a key driver for innovation in the retail sector. Private labels have become brands. The ways of cooperation between a packaging material manufacturer and a retailer could be education and training. Packaging development is of great interest to retailers and they are willing to contribute.
