Design, implementation and testing of DVB/MHP-application development environment

Tämä diplomityö esittelee 1.6. - 4.11.2002 Mikkelin ammattikorkeakoulun YTI-tutkimuskeskuksen Informaatio- ja mediateknologian hankekokonaisuuden STRIMT-projektin puitteissa tekemäni MHP-kehitysjärjestelmähankinnan tuloksia. Digitaalitelevision MHP-sovelluskehitysjärjestelmän hankinnan tulosten lisäksi työ antaa yleiskuvan MHP-sovelluskehitystyökaluista, digitaalitelevisiostandardeista sekä digitaalitelevisioverkkojen yhteistoimintamalleista televerkkojen kanssa. Keräämieni tietojen, tekemäni tarvemäärittelyn ja suorittamani tuotevertailun perusteella valitsin tarpeisiimme sopivimmaksi järjestelmäksi Alticast Inc.-yrityksen Altifusion-tuotteen. Tuotteen valinnassa otin huomioon myös mahdolliset tulevaisuuden tarpeet aina täysimittaista lähetysjärjestelmää varten kehittämällä vaiheittaisen hankintasuunnitelman. Järjestelmää hankittaessa tärkeintä on huomioida heti alusta alkaen mahdolliset tulevat tarpeet ja varmistaa hankinnan hyödynnettävyys myös tulevaisuudessa. Järjestelmän hankinnan lisäksi vastasin sen käyttöönotosta ja järjestelmää hyödyntävän testisovelluksen laatimisesta.

Robots and robotic systems for the electronics and telecommunication industry

Tämä diplomityö tutkii elektroniikka- ja telekommunikaatioteollisuutta sekä siihen läheisesti liittyviä robotteja ja robottijärjestelmiä. Tavoitteena on määrittää E&T-teollisuuden prosesseihin soveltuvien robottien testausmenetelmä. Tavoitteena on myös selvittää kahden ABB:n robotin soveltuvuutta E&T-teollisuuden tarpeisiin. Muutamia systemaattisia valmistusjärjestelmien suunnitteluun soveltuvia menetelmiä ja apuvälineitä on myös käsitelty. Alussa työ keskittyy elektroniikka- ja telekommunikaatioteollisuuden nykytilan tutkimiseen sekä siellä vallitsevien ja ennustettujen trendien kartoitukseen. Kohdat “Collaborative manufacturing” ja E&T-teollisuuden valmistusjärjestelmille asettamat vaatimukset käydään yksityiskohtaisesti läpi. Tutkimuksen pääkohteina ovat robotit, erityisesti ABB:n IRB 140 ja IRB 340 sekä robottien testausmenetelmän määrittäminen. Työssä käydään läpi IRB 340:llä suoritetut testit, jotka tehtiin sekä konenäköjärjestelmää apuna käyttäen että ilman. Myös TTKK:lla suoritetut robottitestit on käyty läpi. Robottien testituloksia on analysoitu ja vertailtu muihin robotteihin. Testausmenetelmät perustuvat ISO 9283 standardiin. Viimeinen osa työstä esittelee robottijärjestelmien systemaattiseen suunnitteluun soveltuvia menetelmiä ja apuvälineitä. Esillä ovat mm. Modular function deployment (MFD) ja The system design method (SDM).

International Accounting Standards –normistoon siirtymisen vaikutukset suomalaisten pörssiyritysten taloushallintoon ja tilinpäätökseen

Tutkimuksen päätavoitteena oli selvittää, mitä vaikutuksia IAS-tilinpäätösstandardien käyttöön siirtyminen aiheuttaa suomalaisten pörssiyritysten tilinpäätöksissä ja taloushallinnossa. Tähän tavoitteeseen edettiin alatavoitteiden avulla. Näitä olivat tilinpäätösten kansainvälisen harmonisoinnin, Euroopan Unionin IAS-asetuksen ja itse IAS-tilinpäätöksen selvittäminen. Tutkimusaineisto koostuu kirjallisuudesta ja suomalaisille pörssiyrityksille tehdystä kyselystä. Tutkimuksen teoriaosassa käytetään käsiteanalyyttista ja empiirisessä osassa nomoteettista tutkimusotetta. Tutkielman mukaan tiedon lisääntyminen lisää myönteisyyttä IAS-standardistoa kohtaan. Henkilöstön koulutus onkin avainasemassa siirtymäprojektissa. Toinen merkittävä vaikutus on uuden laskentaohjeistuksen luontitarve. Merkittävin standardi vaikutuksiltaan on IAS 14 Segmenttiraportointi.

Present standards and future perspectives in the treatment of metastatic non-small cell lung cancer.

The development of novel effective immunotherapeutic agents and early clinical data hinting at significant activity in non-small cell lung cancer (NSCLC) has introduced yet another player in the field of management of advanced disease. At present, first-line cytotoxic chemotherapy is generally withheld pending results of molecular testing for any actionable genetic alteration that could lead to targeted treatment, and in their absence chemotherapy is prescribed as a default therapy. Phase III trials comparing head-to-head immune checkpoint inhibitors with standard platinum-based doublet chemotherapy are underway. Second-line chemotherapy is likewise being challenged in phase III trials, one of which having recently reported positive results in advanced squamous cell carcinoma. In tumors harboring actionable transforming genetic alterations such as EGFR mutations and ALK rearrangements, second- and third-generation inhibitors allow for multiple lines of targeted treatment beyond initial resistance, postponing the use of cytotoxic chemotherapy to very late lines of therapy. Chemotherapy as a longstanding but still present standard of care capable of prolonging survival, improving quality of life, and relieving symptoms sees its role increasingly restricted to clinical, immunological, and molecular subsets of patients where its activity and efficacy have never been tested prospectively.

Quality standards in e-business software development

Large enterprises have for many years employed eBusiness solutions in order to improve their efficiency. Smaller companies, however, have not been able to leverage these technologies due to the high level of know-how and resources required in implementing them. To solve this, novel software services are being developed to facilitate eBusiness adoption for the small enterprise with the aim of making B2Bi feasible not only between large organisations but also between trading partners of all sizes. The objective of this study was to find what standards and techniques on eBusiness and software testing and quality assurance fit best for building these new kinds of software considering the requirements their unique eBusiness approach poses. The research was conducted as a literature study with focus on standards on software testing and quality assurance together with standards on eBusiness. The study showed that the current software testing and quality assurance standards do not possess such characteristics as would make select standards evidently better fitted for building this type of software, which were established to be best developed as web services in order for them to meet their requirements. A selection of eBusiness standards and technologies was proposed to support this approach. The main finding in the study was, however, that these kinds of web services that have high interoperability requirements will have to be able to carry out automated interoperability and conformance testing as part of their operation; this objective dictates how the software are built and how testing during software development is to be done. The study showed that research on automated interoperability and conformance testing for web services is still limited and more research is needed to make the building of highly-interoperable web services more feasible.

Horizontal pressures in cylindrical metal silos and comparison with different international standards

The focus of this research was to evaluate the horizontal pressures on a cylindrical metal silo of corrugated walls and flat bottom with 1.82m diameter and 5.4m high, and to compare the values with those obtained theoretically by the ISO 11697, EP 433 and AS 3774 standards. The silo was symmetrically filled and constant speed with wheat cv. soft red for two different height/diameter ratios (H/D) and was unloaded through three orifices with a diameter of 71.6mm, one concentric and two eccentrics. Horizontal pressures were measured on the walls of the silo at three positions using hydraulic type pressure cells. The results showed that shortly after the start of the unloading, there was a mass flow above the quota of H/D = 1.2, whereas below this quota funnel flow occurred. It can be said that the EP 433 standard was more appropriate to predict horizontal pressures in silos in H/D ratio = 1.0, with eccentric unloading. For the H/D ratio = 1.5, AS 3774 standard was the one that produced values closer to the experimental.

Outlining precision boundaries among areas with different variability standards using magnetic susceptibility and geomorphic surfaces

There is an increasing demand for detailed maps that represent in a simplified way the knowledge of the variability of a particular area or region maps. The objective was to outline precision boundaries among areas with different accuracy variability standards using magnetic susceptibility and geomorphic surfaces. The study was conducted in an area of 110 ha, which identified three compartment landscapes based on the geomorphic surfaces model. To determinate pH, organic matter, phosphorus, potassium and magnesium, the total sand and clay, 514 soil samples were collected at depths of 0-0.20 m and 0.60-0.80 m. The sum of base, cationic exchange capacity and base saturation were calculated and the magnetic susceptibility was evaluated in the laboratory using a system based on a balance of analytical precision method. Geomorphic surfaces identification allowed setting specific management areas (locations with maximum homogeneity of soil attributes). The map of spatial variability of magnetic susceptibility can be used to validate the precise boundaries among geomorphic surfaces identified in the field and infer the variability of clay content and soil base saturation.

CSR standards and financial performance in forest industry - Empirical analysis

The definition of corporate social responsibility (CSR) has been developed since 1950s but even today there is no consensus what CSR includes. The main purpose of this thesis was to find out whether financial performance is better among first adopters of CSR standards in forest industry. To support the main purpose it was critical also investigate what kind of companies adopt CSR standards. The empirical part of the thesis based on a survey which was done in 2010 to forest industry companies and financial data that was gathered from different databases from years 2003-2010. According to the research results it seems the early CSR standards adopters benefits the position of the first adopter many times. Especially cash position and solvency of early adopter companies were better than later adopters or those who did not adopt CSR standards at all. Profitability seemed to be better among CSR standards adopters but early adopters did not have significantly better position compared to later adopters. CSR standards adopters were companies that considered themselves as environmental performance pioneers and had employee oriented management.
