BIMS: Biomedical Information Management System

This final year project presents the design principles and prototype implementation of BIMS (Biomedical Information Management System), a flexible software system which provides an infrastructure to manage all information required by biomedical research projects.The BIMS project was initiated with the motivation to solve several limitations in medical data acquisition of some research projects, in which Universitat Pompeu Fabra takes part. These limitations,based on the lack of control mechanisms to constraint information submitted by clinicians, impact on the data quality, decreasing it.BIMS can easily be adapted to manage information of a wide variety of clinical studies, not being limited to a given clinical specialty. The software can manage both, textual information, like clinical data (measurements, demographics, diagnostics, etc ...), as well as several kinds of medical images (magnetic resonance imaging, computed tomography, etc ...). Moreover, BIMS provides a web - based graphical user interface and is designed to be deployed in a distributed andmultiuser environment. It is built on top of open source software products and frameworks.Specifically, BIMS has been used to represent all clinical data being currently used within the CardioLab platform (an ongoing project managed by Universitat Pompeu Fabra), demonstratingthat it is a solid software system, which could fulfill requirements of a real production environment.

On Consumer Decision Strategies: New Approaches for Studying and Aiding Preferential Choices

This dissertation focuses on the strategies consumers use when making purchase decisions. It is organized in two main parts, one centering on descriptive and the other on applied decision making research. In the first part, a new process tracing tool called InterActive Process Tracing (IAPT) is pre- sented, which I developed to investigate the nature of consumers' decision strategies. This tool is a combination of several process tracing techniques, namely Active Information Search, Mouselab, and retrospective verbal protocol. To validate IAPT, two experiments on mobile phone purchase de- cisions were conducted where participants first repeatedly chose a mobile phone and then were asked to formalize their decision strategy so that it could be used to make choices for them. The choices made by the identified strategies correctly predicted the observed choices in 73% (Experiment 1) and 67% (Experiment 2) of the cases. Moreover, in Experiment 2, Mouselab and eye tracking were directly compared with respect to their impact on information search and strategy description. Only minor differences were found between these two methods. I conclude that IAPT is a useful research tool to identify choice strategies, and that using eye tracking technology did not increase its validity beyond that gained with Mouselab. In the second part, a prototype of a decision aid is introduced that was developed building in particular on the knowledge about consumers' decision strategies gained in Part I. This decision aid, which is called the InterActive Choice Aid (IACA), systematically assists consumers in their purchase decisions. To evaluate the prototype regarding its perceived utility, an experiment was conducted where IACA was compared to two other prototypes that were based on real-world consumer decision aids. All three prototypes differed in the number and type of tools they provided to facilitate the process of choosing, ranging from low (Amazon) to medium (Sunrise/dpreview) to high functionality (IACA). Overall, participants slightly preferred the prototype of medium functionality and this prototype was also rated best on the dimensions of understandability and ease of use. IACA was rated best regarding the two dimensions of ease of elimination and ease of comparison of alternatives. Moreover, participants choices were more in line with the normatively oriented weighted additive strategy when they used IACA than when they used the medium functionality prototype. The low functionality prototype was the least preferred overall. It is concluded that consumers can and will benefit from highly functional decision aids like IACA, but only when these systems are easy to understand and to use.

Three essays on major trends in a slow clockspeed industry : the case of industrial automation

The motivation for this research initiated from the abrupt rise and fall of minicomputers which were initially used both for industrial automation and business applications due to their significantly lower cost than their predecessors, the mainframes. Later industrial automation developed its own vertically integrated hardware and software to address the application needs of uninterrupted operations, real-time control and resilience to harsh environmental conditions. This has led to the creation of an independent industry, namely industrial automation used in PLC, DCS, SCADA and robot control systems. This industry employs today over 200'000 people in a profitable slow clockspeed context in contrast to the two mainstream computing industries of information technology (IT) focused on business applications and telecommunications focused on communications networks and hand-held devices. Already in 1990s it was foreseen that IT and communication would merge into one Information and communication industry (ICT). The fundamental question of the thesis is: Could industrial automation leverage a common technology platform with the newly formed ICT industry? Computer systems dominated by complex instruction set computers (CISC) were challenged during 1990s with higher performance reduced instruction set computers (RISC). RISC started to evolve parallel to the constant advancement of Moore's law. These developments created the high performance and low energy consumption System-on-Chip architecture (SoC). Unlike to the CISC processors RISC processor architecture is a separate industry from the RISC chip manufacturing industry. It also has several hardware independent software platforms consisting of integrated operating system, development environment, user interface and application market which enables customers to have more choices due to hardware independent real time capable software applications. An architecture disruption merged and the smartphone and tablet market were formed with new rules and new key players in the ICT industry. Today there are more RISC computer systems running Linux (or other Unix variants) than any other computer system. The astonishing rise of SoC based technologies and related software platforms in smartphones created in unit terms the largest installed base ever seen in the history of computers and is now being further extended by tablets. An underlying additional element of this transition is the increasing role of open source technologies both in software and hardware. This has driven the microprocessor based personal computer industry with few dominating closed operating system platforms into a steep decline. A significant factor in this process has been the separation of processor architecture and processor chip production and operating systems and application development platforms merger into integrated software platforms with proprietary application markets. Furthermore the pay-by-click marketing has changed the way applications development is compensated: Three essays on major trends in a slow clockspeed industry: The case of industrial automation 2014 freeware, ad based or licensed - all at a lower price and used by a wider customer base than ever before. Moreover, the concept of software maintenance contract is very remote in the app world. However, as a slow clockspeed industry, industrial automation has remained intact during the disruptions based on SoC and related software platforms in the ICT industries. Industrial automation incumbents continue to supply systems based on vertically integrated systems consisting of proprietary software and proprietary mainly microprocessor based hardware. They enjoy admirable profitability levels on a very narrow customer base due to strong technology-enabled customer lock-in and customers' high risk leverage as their production is dependent on fault-free operation of the industrial automation systems. When will this balance of power be disrupted? The thesis suggests how industrial automation could join the mainstream ICT industry and create an information, communication and automation (ICAT) industry. Lately the Internet of Things (loT) and weightless networks, a new standard leveraging frequency channels earlier occupied by TV broadcasting, have gradually started to change the rigid world of Machine to Machine (M2M) interaction. It is foreseeable that enough momentum will be created that the industrial automation market will in due course face an architecture disruption empowered by these new trends. This thesis examines the current state of industrial automation subject to the competition between the incumbents firstly through a research on cost competitiveness efforts in captive outsourcing of engineering, research and development and secondly researching process re- engineering in the case of complex system global software support. Thirdly we investigate the industry actors', namely customers, incumbents and newcomers, views on the future direction of industrial automation and conclude with our assessments of the possible routes industrial automation could advance taking into account the looming rise of the Internet of Things (loT) and weightless networks. Industrial automation is an industry dominated by a handful of global players each of them focusing on maintaining their own proprietary solutions. The rise of de facto standards like IBM PC, Unix and Linux and SoC leveraged by IBM, Compaq, Dell, HP, ARM, Apple, Google, Samsung and others have created new markets of personal computers, smartphone and tablets and will eventually also impact industrial automation through game changing commoditization and related control point and business model changes. This trend will inevitably continue, but the transition to a commoditized industrial automation will not happen in the near future.

CR1Dmod: A Matlab program to model 1D complex resistivity effects in electrical and electromagnetic surveys

We have constructed a forward modelling code in Matlab, capable of handling several commonly used electrical and electromagnetic methods in a 1D environment. We review the implemented electromagnetic field equations for grounded wires, frequency and transient soundings and present new solutions in the case of a non-magnetic first layer. The CR1Dmod code evaluates the Hankel transforms occurring in the field equations using either the Fast Hankel Transform based on digital filter theory, or a numerical integration scheme applied between the zeros of the Bessel function. A graphical user interface allows easy construction of 1D models and control of the parameters. Modelling results are in agreement with other authors, but the time of computation is less efficient than other available codes. Nevertheless, the CR1Dmod routine handles complex resistivities and offers solutions based on the full EM-equations as well as the quasi-static approximation. Thus, modelling of effects based on changes in the magnetic permeability and the permittivity is also possible.

Maastoajoneuvon käyttöliittymän reaaliaikasimulaattori

Työn tavoitteena oli kehittää ja toteuttaa reaaliaikasimulaattori maastoajoneuvon käyttöliittymälle, jota ajoneuvon kuljettajakäyttää ajon aikana. Simulaattori oli tarkoitettu ensisijaisesti käyttöliittymän testaukseen, mutta sen pitää olla helposti laajennettavissa esimerkiksi koulutuskäyttöön. Mallinnustyökaluina oli tarkoitus käyttääpääsääntöisesti markkinoilta saatavia valmiita ohjelmistoja. Simulaattorin toteutuksessa käytettiin myös manuaalista ohjelmointia, koska valituilla ohjelmistoilla ei suoraan voinut saavuttaa reaaliaikaista visualisointia. Käsin kirjoitetut koodit hoitavat valmiilla ohjelmistoilla tehtyjen osien välisen tiedonsiirron. Varsinainen mallintaminen oli valituilla ohjelmistoilla helppoa ja nopeaa. Työn tuloksena saatiintoteutettua simulaattori, jonka vaikutelma oli reaaliaikainen. Käytettävyystestit onnistuivat hyvin simulaattorin avulla. Simulointimallin modulaarisuuden ansiosta mallia on helppo päivittää. Simulaattorin jatkokehityksessä oleelliset seikat ovat visualisoinnin parantaminen ja todellista ajoneuvoa vastaavan dynamiikan lisääminen.

GTK+ toolkit on mobile Linux devices

Linux -käyttöjärjestelmä on laajasti käytössä palvelin- ja työpöytätietokoneissa. Linux on lisäämässä suosiotaan kuitenkin myös sulautetuissa laitteissa, kuten PDA:issa, kännyköissä sekä erilaisissateollisuusjärjestelmissä. Näytön koko, suorituskyky ja käytettävyys asettavat omia erityisiä tarpeitaan laitteiden graafiselle käyttöliittymälle. Linux -käyttöjärjestelmälle on olemassa useita käyttöliittymäkirjastoja, joista GTK+ on yksi yleisimmin käytetyistä. Tämä diplomityö esittelee sulautetun Linux -käyttöjärjestelmän ja GTK+ käyttöliittymäkirjaston, selvittäen miten hyvin ne soveltuvat mobiileihin päätelaitteisiin. Yksi suurimmista esteistä työpöytäkäyttöön suunnattujen teknologioiden, kuten GTK+, muokkaamisessa mobiileihin päätelaitteisiin on suorituskyky. Osana tätä työtä kehitettiin GtkPerf -niminen työkalu, jolla GTK+:n suorituskykyä eri alustoilla pystytään helposti mittaamaan ja havaitsemaan mahdollisia pullonkauloja. Tämän työn johtopäätöksenä on, että pienillä muokkailuilla ja optimoinneilla GTK+ soveltuu myös mobiileihin päätelaitteisiin. Ensimmäinen kaupallisesti saatavilla oleva GTK+ -pohjainen päätelaite, Nokia 770 Internet Tablet, on tästä osoituksena.

Kontekstitietoisen mobiilipelin suunnittelu ja toteutus

Kontekstitietoisuuden katsotaan voivan parantaa sovellusten ja palvelujen käytettävyyttä matkapuhelimissa. Kontekstitietoisuuden tekniikoita voidaan käyttää myös peleissä, joko siksi, että ne mahdollistavat uudenlaisia pelejä, tai siksi, että peleillä voidaan havainnollistaa ja testata eri tekniikoiden toimintaa. Diplomityössä esitellään prototyyppi monen pelaajan kontekstitietoisesta mobiilipelistä, jossa pelivälineinä käytetään kamerapuhelimella luettavia tavallisia viivakoodeja. Viivakoodit on yhdistetty palvelimella sijaitsevan pelimaailman kohteisiin, joiden omistuksesta pelaajat kilpailevat. Peliä on tarkoitus arvioida myöhemmin pelattavuuden ja idean kiinnostavuuden kannalta. Prototyypin toinen tehtävä on havainnollistaa Multi-User Publishing Environment (MUPE) -sovellusalustan tukea kontekstitietoisuudelle. Työ kuvaa pelin suunnittelun, toteutuksen ja arvioinnin alkaen varhaisimmista ideoista ja päättyen osittaiseen prototyyppiin. Prototyypissä on toteutettu osa pelilogiikasta ja käyttöliittymästä, mutta sitä ei ole integroitu kontekstitietoa kerääviin sensoreihin. Pelin suunnittelussa käytettiin apuna heuristista arviointia ja kahta fokusryhmähaastattelua.

Hallintasovellus M2M-tiedonsiirtoon GPRS-verkossa

Pääosa matkapuhelinjärjestelmien liikenteestä on toistaiseksi puhetta. Dataliikenteen osuus on kuitenkin jatkuvasti kasvamassa uusien tekniikoiden myötävaikutuksella. Langattoman dataliikenteen kehittämiselle tuo myös lisäpainetta internetin nopeasti yleistynyt käyttö. Eräs lupaavimmista sovellusalueista on konekommunikaatio, M2M, minkä läpilyöntiä on ennustettu jo vuosia. Viime vuosina markkinoille tulleet M2M-laitteet tarjoavat aiemmista laitteista poiketen myös mahdollisuuden sovellusten suorittamiseen itse laitteessa ja niiden päivittämisen langattomasti. Työssä vertaillaan kolmea markkinoilla olevaa konekommunikaatioon soveltuvaa laitetta ja tarkastellaan niiden ominaisuuksia ja sovellusten päivitettävyyttä GPRS-verkkoa käyttäen. Tarkastelussa havaitaan, että teleoperaattoreiden asettamat rajoitukset ja käytössä olevat päivitysmenetelmät aiheuttavat tiettyjä ongelmia päivitysten käytettävyydelle. Työn tuloksena kehitettiin hallintasovellusohjelmisto, mikä mahdollisti etäällä sijaitsevien M2M-laitteiden sovellusten päivittämisen helppokäyttöisen käyttöliittymän avulla. Hallintasovellusta käyttäen useita, maantieteellisesti hajallaan olevia laitteita oli mahdollista päivittää samanaikaisesti automatisoidusti. Hallintasovellus osoittautui käyttökelpoiseksi työkaluksi M2Mlaitteiden sovellusten hallintaan jo, kun laitemäärä kasvoi muutamista kappaleista muutamaan kymmeneen.
