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.

Selective catalytic reduction of nitrogen oxides with ammonia in forced unsteady state reactors - Case based reasoning and mathematical model simulation reasoning

The application of forced unsteady-state reactors in case of selective catalytic reduction of nitrogen oxides (NOx) with ammonia (NH3) is sustained by the fact that favorable temperature and composition distributions which cannot be achieved in any steady-state regime can be obtained by means of unsteady-state operations. In a normal way of operation the low exothermicity of the selective catalytic reduction (SCR) reaction (usually carried out in the range of 280-350°C) is not enough to maintain by itself the chemical reaction. A normal mode of operation usually requires supply of supplementary heat increasing in this way the overall process operation cost. Through forced unsteady-state operation, the main advantage that can be obtained when exothermic reactions take place is the possibility of trapping, beside the ammonia, the moving heat wave inside the catalytic bed. The unsteady state-operation enables the exploitation of the thermal storage capacity of the catalyticbed. The catalytic bed acts as a regenerative heat exchanger allowing auto-thermal behaviour when the adiabatic temperature rise is low. Finding the optimum reactor configuration, employing the most suitable operation model and identifying the reactor behavior are highly important steps in order to configure a proper device for industrial applications. The Reverse Flow Reactor (RFR) - a forced unsteady state reactor - corresponds to the above mentioned characteristics and may be employed as an efficient device for the treatment of dilute pollutant mixtures. As a main disadvantage, beside its advantages, the RFR presents the 'wash out' phenomena. This phenomenon represents emissions of unconverted reactants at every switch of the flow direction. As a consequence our attention was focused on finding an alternative reactor configuration for RFR which is not affected by the incontrollable emissions of unconverted reactants. In this respect the Reactor Network (RN) was investigated. Its configuration consists of several reactors connected in a closed sequence, simulating a moving bed by changing the reactants feeding position. In the RN the flow direction is maintained in the same way ensuring uniformcatalyst exploitation and in the same time the 'wash out' phenomena is annulated. The simulated moving bed (SMB) can operate in transient mode giving practically constant exit concentration and high conversion levels. The main advantage of the reactor network operation is emphasizedby the possibility to obtain auto-thermal behavior with nearly uniformcatalyst utilization. However, the reactor network presents only a small range of switching times which allow to reach and to maintain an ignited state. Even so a proper study of the complex behavior of the RN may give the necessary information to overcome all the difficulties that can appear in the RN operation. The unsteady-state reactors complexity arises from the fact that these reactor types are characterized by short contact times and complex interaction between heat and mass transportphenomena. Such complex interactions can give rise to a remarkable complex dynamic behavior characterized by a set of spatial-temporal patterns, chaotic changes in concentration and traveling waves of heat or chemical reactivity. The main efforts of the current research studies concern the improvement of contact modalities between reactants, the possibility of thermal wave storage inside the reactor and the improvement of the kinetic activity of the catalyst used. Paying attention to the above mentioned aspects is important when higher activity even at low feeding temperatures and low emissions of unconverted reactants are the main operation concerns. Also, the prediction of the reactor pseudo or steady-state performance (regarding the conversion, selectivity and thermal behavior) and the dynamicreactor response during exploitation are important aspects in finding the optimal control strategy for the forced unsteady state catalytic tubular reactors. The design of an adapted reactor requires knowledge about the influence of its operating conditions on the overall process performance and a precise evaluation of the operating parameters rage for which a sustained dynamic behavior is obtained. An apriori estimation of the system parameters result in diminution of the computational efforts. Usually the convergence of unsteady state reactor systems requires integration over hundreds of cycles depending on the initial guess of the parameter values. The investigation of various operation models and thermal transfer strategies give reliable means to obtain recuperative and regenerative devices which are capable to maintain an auto-thermal behavior in case of low exothermic reactions. In the present research work a gradual analysis of the SCR of NOx with ammonia process in forced unsteady-state reactors was realized. The investigation covers the presentationof the general problematic related to the effect of noxious emissions in the environment, the analysis of the suitable catalysts types for the process, the mathematical analysis approach for modeling and finding the system solutions and the experimental investigation of the device found to be more suitable for the present process. In order to gain information about the forced unsteady state reactor design, operation, important system parameters and their values, mathematical description, mathematicalmethod for solving systems of partial differential equations and other specific aspects, in a fast and easy way, and a case based reasoning (CBR) approach has been used. This approach, using the experience of past similarproblems and their adapted solutions, may provide a method for gaining informations and solutions for new problems related to the forced unsteady state reactors technology. As a consequence a CBR system was implemented and a corresponding tool was developed. Further on, grooving up the hypothesis of isothermal operation, the investigation by means of numerical simulation of the feasibility of the SCR of NOx with ammonia in the RFRand in the RN with variable feeding position was realized. The hypothesis of non-isothermal operation was taken into account because in our opinion ifa commercial catalyst is considered, is not possible to modify the chemical activity and its adsorptive capacity to improve the operation butis possible to change the operation regime. In order to identify the most suitable device for the unsteady state reduction of NOx with ammonia, considering the perspective of recuperative and regenerative devices, a comparative analysis of the above mentioned two devices performance was realized. The assumption of isothermal conditions in the beginningof the forced unsteadystate investigation allowed the simplification of the analysis enabling to focus on the impact of the conditions and mode of operation on the dynamic features caused by the trapping of one reactant in the reactor, without considering the impact of thermal effect on overall reactor performance. The non-isothermal system approach has been investigated in order to point out the important influence of the thermal effect on overall reactor performance, studying the possibility of RFR and RN utilization as recuperative and regenerative devices and the possibility of achieving a sustained auto-thermal behavior in case of lowexothermic reaction of SCR of NOx with ammonia and low temperature gasfeeding. Beside the influence of the thermal effect, the influence of the principal operating parameters, as switching time, inlet flow rate and initial catalyst temperature have been stressed. This analysis is important not only because it allows a comparison between the two devices and optimisation of the operation, but also the switching time is the main operating parameter. An appropriate choice of this parameter enables the fulfilment of the process constraints. The level of the conversions achieved, the more uniform temperature profiles, the uniformity ofcatalyst exploitation and the much simpler mode of operation imposed the RN as a much more suitable device for SCR of NOx with ammonia, in usual operation and also in the perspective of control strategy implementation. Theoretical simplified models have also been proposed in order to describe the forced unsteady state reactors performance and to estimate their internal temperature and concentration profiles. The general idea was to extend the study of catalytic reactor dynamics taking into account the perspectives that haven't been analyzed yet. The experimental investigation ofRN revealed a good agreement between the data obtained by model simulation and the ones obtained experimentally.

The Connectivity of Musical Aptitude and Foreign Language Learning Skills: Neural and Behavioural Evidence

Given the structural and acoustical similarities between speech and music, and possible overlapping cerebral structures in speech and music processing, a possible relationship between musical aptitude and linguistic abilities, especially in terms of second language pronunciation skills, was investigated. Moreover, the laterality effect of the mother tongue was examined with both adults and children by means of dichotic listening scores. Finally, two event-related potential studies sought to reveal whether children with advanced second language pronunciation skills and higher general musical aptitude differed from children with less-advanced pronunciation skills and less musical aptitude in accuracy when preattentively processing mistuned triads and music / speech sound durations. The results showed a significant relationship between musical aptitude, English language pronunciation skills, chord discrimination ability, and sound-change-evoked brain activation in response to musical stimuli (durational differences and triad contrasts). Regular music practice may also have a modulatory effect on the brain’s linguistic organization and cause altered hemispheric functioning in those who have regularly practised music for years. Based on the present results, it is proposed that language skills, both in production and discrimination, are interconnected with perceptual musical skills.

The Usage of Microsoft Push Notification Service on Mobile Devices

Along with the increasing in demand of mobile computing, Push Notification (PN) is widely used in mobile phones and other devices. PN allows the developer to send messages to the end users even when the client application is not running at the moment. This solves the problem produced by non-supported multi-tasking feature as well as saving battery life. Microsoft Push Notification Service (MPNS) is one solution to use PNs in Windows Phones. The thesis gives the developers an idea of how to use PNs by introducing MPNS, comparing MPNS with other Push Notification Services, usage of different PN types analysis, and PN simulation system implementation.

Potential and Challenges of Analog Reconfigurable Computation in Modern and Future CMOS

In this work, the feasibility of the floating-gate technology in analog computing platforms in a scaled down general-purpose CMOS technology is considered. When the technology is scaled down the performance of analog circuits tends to get worse because the process parameters are optimized for digital transistors and the scaling involves the reduction of supply voltages. Generally, the challenge in analog circuit design is that all salient design metrics such as power, area, bandwidth and accuracy are interrelated. Furthermore, poor flexibility, i.e. lack of reconfigurability, the reuse of IP etc., can be considered the most severe weakness of analog hardware. On this account, digital calibration schemes are often required for improved performance or yield enhancement, whereas high flexibility/reconfigurability can not be easily achieved. Here, it is discussed whether it is possible to work around these obstacles by using floating-gate transistors (FGTs), and analyze problems associated with the practical implementation. FGT technology is attractive because it is electrically programmable and also features a charge-based built-in non-volatile memory. Apart from being ideal for canceling the circuit non-idealities due to process variations, the FGTs can also be used as computational or adaptive elements in analog circuits. The nominal gate oxide thickness in the deep sub-micron (DSM) processes is too thin to support robust charge retention and consequently the FGT becomes leaky. In principle, non-leaky FGTs can be implemented in a scaled down process without any special masks by using “double”-oxide transistors intended for providing devices that operate with higher supply voltages than general purpose devices. However, in practice the technology scaling poses several challenges which are addressed in this thesis. To provide a sufficiently wide-ranging survey, six prototype chips with varying complexity were implemented in four different DSM process nodes and investigated from this perspective. The focus is on non-leaky FGTs, but the presented autozeroing floating-gate amplifier (AFGA) demonstrates that leaky FGTs may also find a use. The simplest test structures contain only a few transistors, whereas the most complex experimental chip is an implementation of a spiking neural network (SNN) which comprises thousands of active and passive devices. More precisely, it is a fully connected (256 FGT synapses) two-layer spiking neural network (SNN), where the adaptive properties of FGT are taken advantage of. A compact realization of Spike Timing Dependent Plasticity (STDP) within the SNN is one of the key contributions of this thesis. Finally, the considerations in this thesis extend beyond CMOS to emerging nanodevices. To this end, one promising emerging nanoscale circuit element - memristor - is reviewed and its applicability for analog processing is considered. Furthermore, it is discussed how the FGT technology can be used to prototype computation paradigms compatible with these emerging two-terminal nanoscale devices in a mature and widely available CMOS technology.

The importance of environmental sustainability in public procurement of medical devices in health care sector

The aim of this thesis was to examine the role of environmental sustainability in the procurement of medical devices in health care sector. Current literature is mainly focused on other product groups and medical devices have been left without sufficient attention. Nevertheless, EU has recently developed green public procurement criteria for medical devices (EU GPP criteria for health care EEE) in order to support and offer guidelines for purchasers in hospitals. In this study, the criteria were used as a framework in order to examine the most significant environmental aspects for medical devices. The empirical research was executed in Finnish public hospitals with mixed method approach; quantitative data was collected by a survey and qualitative data was collected by interviews held for procurement specialists. The focus was on understanding the importance of environmental sustainability in the procurement of medical devices and which environmentally sustainable features would be the most significant. Of interest was also the medical device supplier view and how they could take environmental sustainability into consideration.

Paikkatietoalustan hyödyntäminen mobiilipalveluissa

Matkailualan palvelujen kehitystä on pitkään hidastanut standardien ja yhtenäisten toimintatapojen puute. Tässä diplomityössä tarkastellaan standardien merkitystä teknisesti kehittyneille matkailupalveluille ja esitellään TravelGate Finland -hankkeen tuloksena syntynyttä mobiilisovellusta. Kehittyneiden matkaviestinverkkojen ja älypuhelimien ansiosta yhä useammilla ihmisillä on mahdollisuus käyttää matkustaessaan erilaisia mobiilipalveluja. Matkailualan yritysten tarjoamia palveluita ei kuitenkaan ole juurikaan saatavilla, koska niiden kehittäminen on standardien puuttumisen takia hankalaa ja kallista. TravelGate Finland -hankkeen tuloksena matkailualan käyttöön määriteltiin uusi rajapintakirjasto, jonka avulla uusien Internet- ja mobiilipalvelujen kehittäminen helpottuu. Uusien rajapintojen ja toimintatapojen avulla toteutettiin Symbian-älypuhelimissa toimiva mobiilisovellus, jonka avulla matkailijat voivat etsiä heitä lähellä olevien matkailukohteiden sijainnin ja perustiedot veloituksetta.

Tukkilajittelun röntgenmittauksen hyödyntäminen, tapaus Korkeakosken saha

Diplomityön tavoitteena oli selvittää työn toimeksiantajan UPM, Korkeakosken sahan röntgenmittauslaitteen oksaindeksilajitteluparametrille lukuarvo, jolla päästään A-tukkien osalta tavoiteltuun sydänsahatavaralaatujakaumaan eli saadaan siirrettyä VI- sydänsahatavaralaatu B-tukkien joukkoon. Lisäksi työssä tutkittiin sahan tukkilajittelun röntgenmittauslaitteen mittauksen toimivuutta ja sen tehokkaampaa hyödyntämistä. Korkeakosken sahan käyttämä röntgenmittauslaite on Bintec Oy:n kehittämä ja on tyypiltään Wood-X-4D. Laitteen mittaus perustuu tukin kuvaamiseen viipaleinaeli tomografiamittaukseen. Laite mittaa tukista useita ominaisuuksia ja antaa niiden perusteella lajitteluparametreille lukuarvoja. Lajitteluparametriarvojen muuttaminen vaikuttaa syntyvään sydänsahatavaralaatujakaumaan. Työ suoritettiin röntgenmittauslaitteella tekemällä tukeille toistomittauksia ja lajittelukokeita. Kokeissa käytettävät tukit olivat halkaisijaltaan 230 mm - tukkiluokasta. Tukkeja lajiteltiin eri tukkilaatulajitteluasetuksilla, jolloin seurattiin niistä sahattavia sahatavaralaatuja. Sahatavaralaatujen määrityksessä käytettiin sahaosastolla olevaa Finscan Oy:n kehittämää BoardMaster-NT-lajittelumittalaitetta. Tutkimus osoitti, että oksaindeksin pudottamisella, ei päästy työnantajan asettamaan sydänsahatavaran laatulajittelutavoitteeseen sallituissa oksaindeksirajoissa. Tavoitteen saavuttaminen olisi edellyttänyt oksaindeksin arvon pudottamista selkeästi alle asetetun 28 rajan. Tutkimustulokset osoittivat, että röntgenmittalaitteen lajitteluparametrien toiminnan varmuus vaihteli merkittävästi riippuen käytettävästä parametrista ja että laitteen mittaustarkkuus kärsi laitteen yleiseksi viaksi todetun detektorivian myötä. Täten tarkka laatulajittelu edellyttää röntgenmittalaitteen kaikkia neljää toimivaa detektoria. Tämä pystytään varmistamaanvaradetektorilla.

Bluetooth™ Teknologia - Bluetooth Wireless Technology - on lyhyen kantaman langaton kommunikointiteknologia. Vaikka se onkin ensisijaisesti suunniteltu kaapelin korvaajaksi laitteiden omaan toimintaan liittyvässä liikenteessä, voidaan sitä myös käyttää alustana monen käyttäjien peleissä ja muissa vastaavissa sovelluksissa. Tassa diplomityössä esitellään Bluetooth teknologia sovellusohjelmoijan näkökulmasta. Työssä esitellään teollisuuskonsortion määrittelemä Java-ohjelmointirajapinta Bluetooth teknologiaan. Tämän rajapinnan avulla voidaan kehittää kannettavia sovelluksia jotka kommunikoivat Bluetooth yhteyden yli. Rajapinta pohjautuu "Java™ 2 Microedition" alustaan ja on siten toteutettavissa myös pienissä laitteissa kuten matkapuhelimissa. Työssä esitellään lyhyesti rajapinnan keskeiset osat sekä annetaan esimerkki rajapinnan käytöstä. Työn konstruktiivisessa osassa rajapinnan keskeiset on toteutettu kahdelle eri alustalle: Sambian™ ja Microsoft® Windows® käyttöjärjestelmille. Talla tavalla on saatu arvokasta tietoa siitä, miten kyseinen rajapinta tulisi toteuttaa ja myös siitä miten sovellukset sitä käyttäisivät. Keskeiset suunnitteluratkaisut ja saadut kokemukset on raportoitu työn kirjallisessa osassa. Vaikka työn konstruktiivinen osuus onkin luonteeltaan esitutkimus eikä tähdännyt tuotteeseen, on tuloksena syntynyttä rajapintaa tarkoitus käyttää useassa Nokian sisäisessä tutkimus-ja kehityshankkeessa.

Vanhusten hyvä kotona asuminen: tutkimusta kuntatuottavuudesta, älykodeista ja apuvälinepalveluprosesseista

The purpose of the research was to investigate operational processes related to home care of the elderly as well as use of assistive devices in smart home environments, and operational processes that are generally related to use of assistive devices – from the point of view of productivity improvement. The themes were looked into from the points of view of both the elderly and care personnel. In addition, perspectives of near relatives of the elderly, of the larger service system as well as of companies that provided assistive devices to the smart homes were taken into consideration. In the study of home care processes, 32 customer interviews and 17 employee interviews were carried out. This report contains a summary that is based on a separate report of the home care study. The study of home care was conducted in 2006. The use of technological and mechanical assistive devices and the related operational processes were investigated with the help of the smart home pilot in 2007–2008. The study is described in this report. The smart home pilot was implemented in four different housing service units for elderly people at Lahti, Nastola and Hollola. They were in use during short-term housing periods related to, for instance, end of hospitalisation, holidays of caring relatives and assessment of living and housing conditions. More than 60 different assistive devices and technologies were brought to the smart homes. During the pilot period, experiences of customers and personnel as well as processes related to the use of assistive devices were investigated. The research material consisted of 20 survey questionnaires of personnel and customers, four interviews with customers, five interviews with personnel, feedback survey responses from 14 companies, and other data that were collected, for instance, in orientation events. The research results highlighted the need for tailored services based on an elderly person’s needs and wishes, while taking advantage of innovative and technological solutions. As in the earlier home care study, also assistive device-related operational processes were looked into with the help of concepts of ‘resource focus’, ‘lost motion’ and ‘intermediate landing’. The following were identified as central operational processes in assistive device-related services (regardless of the service provider): (1) acquisition process of technologies and assistive devices as well as of rearrangement and rebuilding works in the home, (2) introduction and orientation process (of the elderly, their relatives and care personnel), (3) information and communication process, and (4) service and monitoring process. In addition, the research focused on design and desirability of assistive devices as well as their costs, such as opportunity costs. The process-based points of view gave new knowledge that may be used in the future to develop service processes and clarify their ownership so that separately managed cross-functional processes could be built with participants from different sectors to operate alongside organisations of elderly care. Development of functionality of assistive device-related services is a societally significant issue.

Hitsaustuotannon kehittäminen pk-konepajassa

Kustannusten pienentäminen hitsauksessa on loputon tie. Pääosa hitsauksen kustannuksista muodostuu hitsaukseen käytetystä ajasta. Tämä diplomityö on tarkoitettu avustamaan yrityksiä mekanisoinnin ja robotisoinnin käyttöönotossa sekä mekanisointilaitteiden ja hitsausrobottien investoinneissa ja niiden kannattavuuden arvioimisessa.

Lisäksi selvitetään kolmella yritys-case-esimerkillä hitsausajan vähentämisen vaikutusta kustannuksiin. Samalla esitetään sopivia laitteistoinvestointeja, joilla hitsausajan vähentäminen on mahdollista, sekä tarkastellaan näiden investointien kannattavuutta sekä syntyviä säästöjä.

Haja-asutusalueen keskijänniteverkon kaapeloinnin ja automaation suunnittelumetodiikka

Tässä diplomityössä tutkitaan erilaisia keskijänniteverkon kehittämismenetelmiä sekä suunnittelua haja-asutusalueelle. Suunnittelumetodiikan perustana on vertailla sähköverkon käyttövarmuuden tunnuslukujen sekä kokonaiskustannusten kehittymistä erilaisilla investointiratkaisuilla. Lähemmässä tarkastelussa ovat erilaiset kaapelointimenetelmät sekä automaatiolaitteet kuten maastoon sijoitettavat katkaisijat sekä kauko-ohjattavat erottimet. Kehittämisratkaisujen vertailemiseksi sähköverkosta muodostetaan laskentaa varten malli, jonka avulla on mahdollista tarkastella mm. käyttövarmuuden tunnuslukujen sekä verkon kustannusten kehittymistä. Verkon kustannuksissa otetaan huomioon investointikustannukset, käyttö- ja kunnossapitokustannukset, viankorjauskustannukset sekä keskeytyskustannukset. Keskeytysten laskentaa varten toteutetaan erilliset laskentalohkot, jotta keskeytyskustannukset saadaan mallinnettua tarkasti. Kaapelointistrategia-analyysissä vertaillaan kaapeloinnin erilaisia toteuttamisperiaatteita. Erilaisia tutkittavia kaapelointimenetelmiä ovat vyörytysmenetelmä, vikaherkimpien kohteiden uusinta, vanhimpien kohteiden uusinta, täydellinen kaapelointi sekä optimiverkostoratkaisu, jossa on hyödynnetty keskijännitejohtojen kaapeloinnin lisäksi mm. automaatioratkaisuja ja 1000 V tekniikkaa. Kaapelointimenetelmiä vertailtaessa on havaittu, että vikaherkimmistä kohteista aloitettava saneeraus tuottaa parhaimman tuloksen, jos optimiratkaisua ei oteta huomioon.

Lasikuituputkien kelauslinjan automatisointi

Lasikuituputkien kelaamiseen tarkoitettu automaatio voidaan toteuttaa suorakulmaisen kolmion trigonometrian perusteella. Kelaaminen tapahtuu pyörittämällä muottia ja liikuttamalla samalla muottia sivuttain. Näin tehdessä saadaan kelattavat lasikuitulangat leviämään koko muotin leveydelle. Jos langat halutaan saada kelattua tiiviisti toistensa viereen, on muotin liikuttava tietty matka yhtä muotin pyörähdystä kohden. Matkaa kutsutaan nousuksi. Nousu riippuu lankojen muodostaman kimpun leveydestä, kelauskulmasta ja muotin säteestä. Kelauskulmalla voidaan vaikuttaa kelattavan tuotteen aksiaaliseen ja pitkittäiseen lujuuteen. Kelauskoneen automaatiojärjestelmä koostuu sähkökäytöistä, ohjaavasta yksiköstä, valvomosta ja erilaisista antureista. Eri osat yhdistetään toisiinsa väylätekniikalla. Sähkökäytöt ovat yleensä servokäyttöjä, koska niiltä vaaditaan tarkkuutta ja nopeutta. Ohjaavana yksikkönä toimii yleensä teollisuus logiikka. Anturointia tarvitaan esimerkiksi hartsin lämpötilan säätöön ja lankojen ratakireyden säätöön. Anturoinnilla ja säädöillä pyritään parantamaan kelattavan tuotteen laatua. Koneen ohjelmallinen toteutus vaatii kelauskoneen mekaniikan ja kelausprosessin ymmärtämistä. Lisäksi on huomioitava koneen käyttäjät ja heidän turvallisuus.
