The legal framework for energy provisions in the European Union – With special regard to providing of energy provisions within the scope of Article 194(2) TFEU

The thesis interprets the caveat of Article 194(2) TFEU in order to assess the use of the Article as a legal basis for energy provisions provided by the European Union. The research subject is the Energy Title in the Treaty of the Functioning of the European Union and the possibilities of the application of the legal basis provided therein. The purpose is analysis of the possibilities for providing of provisions within the scope of the caveat found in Article 194(2) TFEU with special regard to the possibilities of providing renewable energy legislation. The purpose of the thesis is on one hand to provide an overview of the premises for providing of energy provisions in the EU, and on the other hand to analyse the Treaty text in order to determine the legal basis for energy provisions. The ultimate objective is to determine the correct legal basis for renewable energy provisions, aimed at the mitigation of climate change. According to Article 194(2) TFEU, the practice of the shared legislative powers in the field of energy are restricted by the retention of certain energy matters within the power of the Member States. The wording of the caveat containing the restrictions is open to interpretation and has been a subject of extensive discussion. Many scholars have argued that the caveat in Article 194(2) TFEU might obstruct decision-making in energy matters. This argument is contested, and the factual impact of the codification of the energy competences is analysed. The correct legal basis for energy provisions depends on the final interpretation of the text of the caveat and the level of significance of the effect of the measure. The use of Article 194(2) TFEU as a legal basis might not be the only option. There is a possibility that the legal bases within the Environmental Title might be used as legal bases for energy provisions in addition to Article 194(2) TFEU.

Centralized Motion Control of a Linear Tooth Belt Drive: Analysis of the Performance and Limitations

A centralized robust position control for an electrical driven tooth belt drive is designed in this doctoral thesis. Both a cascaded control structure and a PID based position controller are discussed. The performance and the limitations of the system are analyzed and design principles for the mechanical structure and the control design are given. These design principles are also suitable for most of the motion control applications, where mechanical resonance frequencies and control loop delays are present. One of the major challenges in the design of a controller for machinery applications is that the values of the parameters in the system model (parameter uncertainty) or the system model it self (non-parametric uncertainty) are seldom known accurately in advance. In this thesis a systematic analysis of the parameter uncertainty of the linear tooth beltdrive model is presented and the effect of the variation of a single parameter on the performance of the total system is shown. The total variation of the model parameters is taken into account in the control design phase using a Quantitative Feedback Theory (QFT). The thesis also introduces a new method to analyze reference feedforward controllers applying the QFT. The performance of the designed controllers is verified by experimentalmeasurements. The measurements confirm the control design principles that are given in this thesis.

Predicting Market Crashes: An Examination of the Performance of Macroeconomic Indicators and Technical Analysis

The purpose of this study is to examine macroeconomic indicators‟ and technical analysis‟ ability to signal market crashes. Indicators examined were Yield Spread, The Purchasing Managers Index and the Consumer Confidence Index. Technical Analysis indicators were moving average, Moving Average Convergence-Divergence and Relative Strength Index. We studied if commonly used macroeconomic indicators can be used as a warning system for a stock market crashes as well. The hypothesis is that the signals of recession can be used as signals of stock market crash and that way a basis for a hedging strategy. The data is collected from the U.S. markets from the years 1983-2010. Empirical studies show that macroeconomic indicators have been able to explain the future GDP development in the U.S. in research period and they were statistically significant. A hedging strategy that combined the signals of yield spread and Consumer Confidence Index gave most useful results as a basis of a hedging strategy in selected time period. It was able to outperform buy-and-hold strategy as well as all of the technical indicator based hedging strategies.

Pulsed corona discharge as an advanced oxidation process for degradation of organic

Advanced oxidation processes (AOPs) have been studied and developed to suffice the effective removal of refractory and toxic compounds in polluted water. The quality and cost of wastewater treatment need improvements, and electric discharge technology has a potential to make a significant difference compared to other established AOPs based on energy efficiency. The generation of active oxidant species such as ozone and hydroxyl radicals by high voltage discharge is a relatively new technology for water treatment. Gas-phase pulsed corona discharge (PCD), where a treated aqueous solution is dispersed between corona-producing electrodes free of the dielectric barriers, was developed as an alternative approach to the problem. The short living radicals and ozone formed in the gas phase and at the gas-liquid interface react with dissolved impurities. PCD equipment has a relatively simple configuration, and with the reactor in an enclosed compartment, it is insensitive towards gas humidity and does not need the gas transport. In this thesis, PCD was used to study and evaluate the energy efficiency for degrading various organic compounds, as well as the chemistry of the oxidation products formed. The experiments investigate the aqueous oxidation of phenol, humic substances, pharmaceutical compounds (paracetamol, ibuprofen, indomethacin, salicylic acids, -estradiol), as well as lignin degradation and transformation to aldehydes. The study aims to establish the influence of initial concentration of the target pollutant, the pulsed discharge parameters, gas phase composition and the pH on the oxidation kinetics and the efficiency. Analytical methods to measure the concentrations of the target compounds and their by-products include HPLC, spectrophotometry, TOC and capillary electrophoresis. The results of the research included in this summary are presented in the attached publications and manuscripts accepted for publication. Pulsed corona discharge proved to be highly effective in oxidizing each of the target compounds, surpassing the closest competitor, conventional ozonation. The increase in oxidation efficiencies for some compounds in oxygen media and at lower pulse repetition frequencies shows a significant role of ozone. The role of the ·OH radicals was established in the surface reactions. The main oxidation products, formation of nitrates, and the lignin transformation were quantified. A compound specific approach is suggested for optimization of the PCD parameters that have the most significant impact on the oxidation energy efficiency because of the different characteristics and responses of the target compound to the oxidants, as well as different admixtures that are present in the wastewater. Further studies in the method’s safety (nitration and nitrosation of organic compounds, nitrite and nitrate formation enhancement) are needed for promoting the method.

Insiders´ views as a predictor of stock performance : can insider trading be used to predict stock performance on the United States stock market?

This thesis studies the possibility of using information on insiders’ transactions to forecast future stock returns after the implementation of Sarbanes Oxley Act in July 2003. Insider transactions between July 2003 and August 2009 are analysed with regression tests to identify the relationships between insiders’ transactions and future stock returns. This analysis is complemented with rudimentary bootstrapping procedures to verify the robustness of the findings. The underlying assumption of the thesis is that insiders constantly receive pieces of information that indicate future performance of the company. They may not be allowed to trade on large and tangible pieces of information but they can trade on accumulation of smaller, intangible pieces of information. Based on the analysis in the thesis insiders’ profits were found not to differ from the returns from broad stock index. However, their individual transactions were found to be linked to future stock returns. The initial model was found to be unstable but some of the predictive power could be sacrificed to achieve greater stability. Even after sacrificing some predictive power the relationship was significant enough to allow external investors to achieve abnormal profits after transaction costs and taxes. The thesis does not go into great detail about timing of transactions. Delay in publishing insiders’ transactions is not taken into account in the calculations and the closed windows are not studied in detail. The potential effects of these phenomena are looked into and they do not cause great changes in the findings. Additionally the remuneration policy of an insider or a company is not taken into account even though it most likely affects the trading patterns of insiders. Even with the limitations the findings offer promising opportunities for investors to improve their investment processes by incorporating additional information from insiders’ transaction into their decisions. The findings also raise questions on how insider trading should be regulated. Insiders achieve greater returns than other investors based on superior information. On the other hand, more efficient information transfer could warrant more lenient regulation. The fact that insiders’ returns are dominated by the large investment stake they maintain all the time in their own companies also speaks for more leniency. As Sarbanes Oxley Act considerably modified the insider trading landscape, this analysis provides information that has not been available before. The thesis also constitutes a thorough analysis of insider trading phenomenon which has previously been somewhat separated into several studies.

Designing of Balanced Performance Measurement System to Purchasing Process

The performance measurement produces information about the operation of the business process. On the basis of this information performance of the company can be followed and improved. Balanced performance measurement system can monitor performance of several perspectives and business processes can be led according to company strategy. Major part of the costs of a company is originated from purchased goods or services are an output of the buying process emphasising the importance of a reliable performance measurement of purchasing process. In the study, theory of balanced performance measurement is orientated and framework of purchasing process performance measurement system is designed. The designed balanced performance measurement system of purchasing process is tested in case company paying attention to the available data and to other environmental enablers. The balanced purchasing performance measurement system is tested and improved during the test period and attention is paid to the definition and scaling of objectives. Found development initiatives are carried out especially in the scaling of indicators. Finally results of the study are evaluated, conclusions and additional research areas proposed.

A Study of Multicast Performance in IEEE 802.11 Wireless Local Area Networks

Langattomat lähiverkot ovat yleistyneet ja monin paikoin niillä pyritään täysin korvaamaan perinteiset kaapeloidut verkot. Samalla verkoissa välitettävät palvelut monipuolistuvat. Etenkin interaktiivisten sisältöjen ja viiveriippuvaisten palvelujen välittämisessä korostuvat verkolle asettavat vaatimukset suorituskyvystä ja palveluntasosta. Radiotaajuuksilla tapahtuva tiedonsiirto on ongelmallista siirtomedian jaetun luonteen vuoksi. Käytettäessä ympärisäteileviä antenneja jokainen kantomatkan päässä oleva asema kuulee lähetyksen, vaikkei se olisi sille suunnattu. Tämä luo turvallisuusongelman, mutta lisäksi heikentää tehokkuutta, koska nykyisellä antenniteknologialla vain yksi asema kerrallaan voi lähettää häiriöttä kantoalueellaan. Täsmälähetykset yhden lähteen ja useiden kohteiden välillä luovat erillisiä siirtolinkkejä. Olisi luontevampaa luoda yksi lähetysvirta, johon useat vastaanottajat voivat kytkeytyä. Kaistan säästön vastapainona on tarve luoda ja ylläpitää näitä yhteyksiä. Käyttäjien liikkuvuuden ja siirtotien vaihtelevien ominaisuuksien vuoksi langattoman verkon rakenne ja rajat ovat epäselviä. Näihin haasteisiin on vastattava sekä protokolla- että sovellustasolla. Tässä tutkielmassa käydään ensin läpi IEEE 802.11 -standardin mukaisen langattoman verkon perusteet ja sen ominaisuuksiin liittyvät tyypilliset ongelmakohdat. Yleis- ja ryhmälähetyksiä tarkastellaan ensin perinteisessä IEEE 802.3 standardin mukaisessa langallisessa lähiverkossa ja selvitetään, miten vastaavat ominaisuudet toteutuvat IEEE 802.11 standardien mukaisissa langattomissa verkoissa. Käyttötapaustutkimuksissa keskitytään rajatussa ympäristössä tapahtuviin ryhmälähetyksiin. Erityisesti tutkitaan langattomien ryhmälähetysten käyttökelpoisuutta sekä langattoman ympäristön asettamia erityisvaatimuksia.

Protocol Specific Embedded Operating System

Sulautettujen järjestelmien määrä kuten niiden sisältämä älykkyyskin ovat viime vuosina kasvaneet merkittävästi. Sulautettujen ohjelmistojen yleistymistä ja monipuolistumista on edesauttanut sulautettujen laitteistojen prosessointitehon merkittävä kehittyminen, jonka myötä entistä vaativampien ohjelmistojen totetuttaminen sulautetusti on mahdollistunut. Seuraavana sulautettujen järjestelmien kehitysaskeleena on nähtävissä järjestelmien kommunikointikyvyn paraneminen ja siten uusien ja uudentyyppisten sulautettujen ratkaisujen toteuttaminen. VTT on päättänyt tutkia sulautettujen järjestelmien kommunikointia ja kehittää sulautettun protokolla-alustan. Tutkimuksen perusta on CVOPS protokollajärjestelmä, jota jatkokehittämällä pyritään toteuttamaan sulautettu protokollajärjestelmä, µCVOPS. Tässä diplomityössä esitetään kommunikaation sulautetulle järjestelmälle asettamia vaatimuksia, järjestelmän suunnittelu ja prototyypitys sulautetulla laitteistolla. Prototyypitykseen on käytetty sulautettua DragonBall mikrokontrolleria jonka käyttöjärjestelmänä käytettiin sulautettua Linux:a. Tälle alustalle on tehty CVOPS:sta modifioitu versio, jolla µCVOPS:ia pystytään simuloimaan.
