4. Prototyping och utveckling med AngularJS [2015]
-
Nordin, Magnus
- Abstract
-
Den digitala marknadsplatsen delbar.se är en hemsida där användare kan hyra/dela ut och låna grejer och tjänster av varandra. Under våren 2015 planerades det att fokus för tjänsten ska förflyttas från generell annonsering till en mer grupporienterad tjänst, där annonsering och uthyrning främst ska ske inom grupper. En del av omstruktureringsarbetet och målet med det här projektet, bestod av att designa och implementera funktionalitet för inbjudning av nya användare till tjänsten. Arbetet under projektet var uppdelat i tre större faser, förstudie, prototyping och slutligen implementering av funktionaliteten i källkod. Under förstudien undersöktes hur liknande digitala tjänster genomför sina inbjudningar av nya användare till tjänsten. Med den insamlande informationen utvecklades sedan ett antal prototyper som presenterades för Delbar. Efter diskussioner och återkoppling kring prototyperna så togs den bästa prototypen vidare till programmering. Den slutliga fasen av projektet bestod alltså av implementering av inbjudningsfunktionaliteten i det resterande systemet. Resultatet av arbetet är implementerad inbjudningsfunktionalitet på webbplatsen delbar.se med hjälp av javascriptramverket AngularJS. Lösningen som implementerats på webbplatsen innehåller funktioner för att bjuda in nya användare genom delning av URL-länk, inmatning av epost adresser och sedan utskick av inbjudan till dessa adresser. Slutligen finns även funktioner för att dela en inbjudningslänk med relevant information på ett antal sociala nätverk, såsom Facebook, Linkedin, Google+ och Twitter.
Delbar.se is a digital marketplace where users can rent/share and borrow various services and items from each other. In the spring of 2015 delbar.se is planing on shifting focus of the site, moving from an add-based website to a more group oriented site, where sales and rental will primarily be done in groups. Part of this reimagining of the site, as well as the purpose of this project, is the implementation of various ways to invite new users to the site. Work in the project were divided into three main stages, a introductory study, prototyping and finally implementation of the invite functionality in the source code. During the introductory stage a couple of similar sites were studied, in order to determine how these handle invites of new users to their sites. Using this information a number of prototypes were developed and presented to Delbar. After discussing the prototypes the best ones were chosen and sent to the programming stage. Finally the look and functionality of the prototypes were implemented in the source code. The resulting functionality is implemented on delbar.se using AngularJS. In its current state the site has functions for inviting new users using URL, entering emails and then sending an invite to the recipients. In addition to this there’s also functions for sharing an invite link using some of the most common social networks, such as Facebook, Linkedin, Google+ and Twitter.

The Digital Signal Processing (DSP) systems used in mobile wireless communication, such as MIMO detection, beam formation in smart antennas, and compressed sensing, all rely on quickly solving linear systems of equations. These applications of DSP have vastly different throughput, latency and area requirements, necessitating substantially different hardware solutions. The QR decomposition (QRD) method is an efficient way of solving linear equation systems using specialized hardware, and is known to be numerically stable [17]. We present the design and FPGA implementation of smart IP (intellectual property) for QRD based on Givens-Rotation (GR) and Modified-Gram- Schmidt (MGS) algorithms. Our configurable designs are flexible enough to meet a wide variety of application requirements. We demonstrate that our area and timing results are comparable, and in some cases superior, to state-of-art hardware-based QRD implementations. Our QRD design based on a Log-domain GR Systolic array achieved a throughput of 10.1M rows/sec for a complex valued 3x3 matrix on Virtex-6 FPGA, whereas our QRD design based on a Log-domain GR Linear array was found to be an area optimized solution requiring the fewest FPGA slices. Overall the Logdomain GR Systolic array implementation was found to be the most resource efficient design (IP for all of our proposed architectures have been prepared and are available at http://saqib.scripts.mit.edu/qr-code.php). Our set of IP can be configured to satisfy variety of application demands, and can be used to generate hardware designs with nearly zero design and debugging time. Moreover the reported results can be used to pick the optimal design choice based on a given set of design requirements. Since our architectures are completely modular, their sub-units can be independently optimized and tested without the need for re-testing the whole system.

- Abstract
-
This paper describes the techniques used to fabricate a one meter long, 1/6 scale model of a Small Waterplane Area, Twin Hull (SWATH) Unmanned Surface Vehicle (USV) that will be used primarily for dynamic seakeeping testing in the MIT Tow Tank. The model represents a design conceived by Stefano Brizzolara, which will be used for launching, recovering, and servicing Unmanned Underwater Vehicles (UUV) at sea. Construction methods included a number of rapid prototyping methods rarely used for this kind of project, including 3D printing, lasercutting, and spraypainting. The benefits and disadvantages of each of these processes will be discussed. Although there was insufficient time to conduct any tow tank tests, several data-recording techniques are reviewed which may be used by future students continuing the research of this vessel.

- Abstract

Most literature in Information Systems are good at pointing out the advantages of having a well thought-out information infrastructure in place in order to support the activities of the organization. They are also good at mentioning the problems that these information infrastructures often have in reality. However, what the literature does not do too well is to provide guidance as to how the integration of a new system into an already existing information infrastructure can be planned and implemented. As Hanseth and Lyytinen points out “a standard text book on object oriented method-ologies (Mathiassen et al., 2000) spends exactly 1% (4.5/450) of it’s pages on systems inte-gration and issues how to relate design to-be with the current environment” (Hanseth and Lyytinen, 2004, footnote, p. 211). This master thesis explores how a new information system can be integrated in the as-is information infrastructure by analyzing the information infrastructure at Uppsala Univer-sity, where they have identified a need to address the existing problems. This is an informa-tion infrastructure that does not fully support the activities of the organization which leaves them with a lot of unnecessary manual work that could instead have been automated. A possible solution to these issues has been found to be the integration of a new system to fill in the gap where the infrastructure does not support the organization. This is a complex op-eration and a complex issue which is also difficult to fully understand. Therefore this master thesis explores and proposes a method where prototyping is used for multiple purposes to elucidate and elicit both business and technical requirements concerning the integration of a system into an existing information infrastructure. 50 user requirements, 5 interaction requirements and 5 information infrastructure re-quirements were generated through the use of the presented approach. The results suggests that this approach indeed can be advantageous in situations where requirements concern-ing the new system as well as the interoperability with other systems in the information infrastructure are not apparent and thus difficult to define.

Denna uppsats avser att undersöka om systemutvecklingsmetoderna RUP och Prototyping kan komplettera och kombineras med varandra. Vidare avser uppsatsen att undersöka hur de fungerar i praktiken men också hur UML och Prototyping kan visualisera och säkra kravlistan för processtyrning inom läkemedelsindustrin. Fallstudien som denna uppsats innehåller är gjord på ett läkemedelsföretag i Sverige. Vid tillverkning av läkemedel användes olika former av pappersbaserad dokumentation som signeras manuellt. Företaget har idag bland annat ingen kontroll över om signeringen utförs under eller efter tillverkningen och enligt GMP strider detta mot de regler och lagar som styr läkemedelstillverkningen. För att hitta de krav användarna ställer på ett kontrollstyrningssystem har både observationer och intervjuer utförts på plats.

- Abstract
-
The topic of this thesis fo cus on the preliminary design and the p erformance analysis of a multirotor platform. A multirotor is an electrically p owered Vertical Take Off (VTOL) machine with more than two rotors that lift and control the platform. Multirotor are agile, compact and robust, making them ideally suited for b oth indo or and outdo or application especially to carry-on several sensors like electro optical multisp ectral sensor or gas sensor. The main disadvantage is the limited endurance due to heavy Li-Po batteries and high disk loading through the use of different small prop ellers. At the same time, the design of the multirotor do es not follow any engineering principle but it follow the ideas of amateurs’ builder. An adaptation of the classic airplane design theory for the preliminary design is implemented to fill the gap and detailed study of the endurance is p erformed to define the right way to make this kind of VTOL platforms.

I dette studiet ser vi på hvordan man kan praktisere brukersentrert utvikling i de tidlige fasene av systemutviklingsløpet for applikasjoner til Microsoft Surface.Vi har sett på to temaer knyttet til dette; introduksjon av ny teknologi for brukere, og metoder for low-fi prototyping og wizard-of-Oz brukbarhetstesting. Ved praktisering av brukersentrert utvikling er det ikke uvanlig at brukerne som involveres har en lav teknisk innsikt. Dette gjelder spesielt for nye teknologier som multi-touchbord, som fremdeles er lite utbredt. Viktigheten av å formidle mulighetene og begrensningene ved Surface til brukerne er derfor stor. I denne oppgaven blir det sett på hvilken merverdi domenespesifikke demonstrasjoner gir fremfor abstrakte når man skal formidle egenskapene ved Surface. Dette blir besvart gjennom to workshops med uavhengige grupper. Den ene gruppen får presentert abstrakte demonstrasjoner, mens den andre får presentert domenespesifikke. Ved å måle og sammenligne idérikdommen på de to workshopene blir det undersøkt hvilken av de to formidlingsmetodene som fungerer best. Resultatene viste imidlertid ingen signifikant forskjell i antall ideer som kom opp i de to workshopene, men typene av ideer hadde et merkbart skille. Det viser seg at domenespesifikke demonstrasjonseksempler ikke har merverdi overfor abstrakte, men at de to metodene snarere utfyller hverandre. I de tidlige fasene av systemutviklingsløpet til en applikasjon for Surface er det hensiktsmessig å utvikle en prototype som kan brukes i wizard-of-Oz brukbarhetstester, slik at brukerne kan evaluere designet og komme med forslag til endringer, nye krav eller bekrefte designløsninger. Vi ser i denne oppgaven på hvilke metoder, verktøy og materialer som bør benyttes ved prototyping, og hvordan disse kan brukbarhetstestes ved bruk av wizard-of-Oz på flere testbrukere samtidig. Ulike teknikker blir utprøvd og disse resulterer i en prototype som blir brukbarhetstestet for en aktuell brukergruppe. Resultatene fra brukbarhetstestene viser at papirprototyping og wizard-of-Oz flerbrukertesting av Surface-applikasjoner lar seg gjennomføre, men at det krever god planlegging. Blant viktige utfordringer som avdekkes er testpersonenes påvirkning av hverandre og viktigheten av å skille mellom fysiske og virtuelle GUI-elementer i prototypen.

Les systèmes RFID sont de plus en plus utilisés dans des applications critiques fonctionnant dans des environnements perturbés (ferroviaire, aéronautique, chaînes de production ou agroalimentaire) ou dans des applications où la sécurité est essentielle (identification, lutte contre la contrefaçon). Pourtant, ces systèmes faibles coûts, initialement conçus pour des applications de masse non critiques, sont peu robustes par nature. Pour les applications critiques, les défaillances des puces RFID peuvent avoir des conséquences catastrophiques ou créer des failles de sécurité importantes. Ces défaillances peuvent avoir des origines nombreuses : par exemple, des origines matérielles dues au vieillissement naturel des circuits intégrés ou à des attaques (optiques, électromagnétiques, en tension). Il est donc d'usage dans les applications critiques d'accroître la robustesse des systèmes RFID par la mise en œuvre de redondance matérielle. Cependant cette redondance accroît le coût du déploiement des systèmes RFID ainsi que la complexité des protocoles et middleware associés. L'amélioration de la robustesse des tags permet de grandement limiter cette redondance. L'objectif de la thèse est d'accroitre la robustesse des tags UHF passifs en proposant et validant de nouvelles architectures numériques de puces RFID robustes à la fois aux défaillances et aux attaques matérielles. Les approches de durcissement des circuits intégrés étudient généralement leur robustesse par simulation et ce de manière indépendante à la validation de leur conception. La méthode la plus courante afin de valider la robustesse d'un circuit repose sur l'injection de fautes par simulation. Pour les puces RFID, ce type d'approche par simulation est problématique car les performances des puces dépendent de nombreux paramètres difficilement modélisables globalement. En effet, le fonctionnement d'un tag dépend de son environnement électromagnétique, du nombre de tags présents dans le système, des protocoles mis en œuvre. Aussi, nous avons développé une méthodologie basée sur le prototypage permettant d'éviter des simulations complexes et chronophages. La puce RFID prototype est alors implantée dans un FPGA. Ainsi, dès la phase de conception, cette puce peut être validée fonctionnellement dans un environnement réel. De plus, en utilisant différentes techniques d'instrumentation permettant l'injection de fautes dans les circuits numériques sur FPGA, il est alors possible d'analyser l'effet sur l'ensemble du système des fautes injectées dans le tag. Dans cette thèse, dans un premier temps, le prototype fonctionnel d'un tag RFID a été développé. Dans un second temps, ce prototype a été instrumenté pour pouvoir réaliser des injections de fautes en ligne ou hors ligne. Ensuite, le comportement du système RFID en présence de fautes dans ce tag RFID a été évalué. L'analyse des effets de ces fautes sur le système a permis de proposer, de mettre en œuvre et de valider de nouvelles architectures numériques de tags RFID robustes. Ce nouvel environnement de prototypage et d'injection de fautes a également permis de démontrer les effets de nouvelles attaques contre les systèmes RFID reposant sur l'insertion de tags fautifs ou malveillants dans les systèmes. Enfin, cette approche a permis d'évaluer les méthodes de détection des tags fautifs.
RFID tags are more and more used for critical applications within harsh environments (aeronautics, railways) or for secure applications such as identification, countermeasure against counterfeiting. However, such low cost systems, initially designed for non-critical applications with a high volume, are not robust by themselves. For critical applications, a malfunction of RFID chip may have serious consequences or induce a severe security breach for hackers. Dysfunctions can have many origins: for instance, hardware issues can be due to aging effects or can also be due to hackers attack such as optical or electromagnetic fault injection. It is thus a common practice for critical applications to increase the robustness of RFID system. The main purpose of this PhD Thesis is to increase UHF tags robustness by proposing new digital architectures of RFID chips which would be resilient against both hardware attacks and natural defects.Usual design techniques for robustness IC improvement consist in evaluating the design robustness by simulation and to do this independently of the design validation. The main technique for robustness evaluation is the simulation based faults injection. Within the RFID context such an approach only based on simulation has several drawbacks. In fact, simulations often are inaccurate because the system behavior relies on several parameters such as the global electromagnetic environment, the number of tags present in the reader field, the RFID protocol parameters.The purposes of this PhD are to develop a design method dedicated to RFID system based on hardware prototyping in order to avoid time consuming simulations and then to evaluate the design within a real environment.The hardware prototyping based on FPGA allows the design to be validated in a real environment. Moreover, using instrumentation techniques for fault injection within FPGA , it will be then possible to analyze the effects of faulty tags on the global system in terms of safety and security and then to propose countermeasures.In this thesis an FPGA based emulation platform called RFIM has been developed. This platform is compliant to EPC C1 Gen2 RFID standard. The RFID tag emulator has been validated functionally in a real environment. The RFIM platform uses the instrumentation technique for injecting faults in the digital tag circuit. Through fault injection campaigns RFIM platform can analyze the effect on the entire system of the faults injected into the tag, and ten validate new robust digital architectures.The RFIM platform has been used to demonstrate the effects of further attacks against RFID systems based on the insertion of faulty or malicious tag that contains a hardware Trojan. Finally, RFIM platform helps to develop countermeasures against the fault effects. These countermeasures have been implemented and tested in a real RFID environment with several tags and reader.

Detta examensarbete är en del i ett utvecklingsarbete som sker för att förenkla arbetet vid prototypframtagning av reglersystem. Inbyggda system blir mer avancerade och komplexa och därmed ökar utvecklarens behov för att enkelt och snabbt komma igång med en första prototyp. Detta genom att testa, verifiera och felsöka direkt på prototypenheten utöver den traditionella kompilator- och debuggmiljön. Detta utvecklingsverktyg kallas On Target Prototyping (OTP).Ett av målen för detta examensarbete har varit att ta fram hårdvara och tillhörande mjukvara till detta utvecklingsverktyg. Kommunikationen mellan OTP plattformen och PC sköts med hjälp av USB och XCP on USB. USB protokollet har ingått i den litteraturstudie som utförts för att utreda förutsättningarna för en snabbare kommunikation än traditionell seriell kommunikation. Det visade sig tyvärr att USB protokollet var mer komplicerat än vad som antogs då examensarbetet startade. I den här tillämpningen med OTP krävs det att data skickas via USB i så nära realtid som möjligt för att kunna analyseras och presenteras i Caldesk. Detta utgör ett problem då USB endast har en överföringstyp, isochronous, som klarar av större datamängder och att data kommer fram vid utsatt tid. Denna typ av överföring har inte möjlighet till omsändning utan meddelar endast att datapaketet innehöll fel. Om man istället väljer att prioritera att rätt data kommer fram genom att felkontroll tillämpas (bulk, control och interrupt) sjunker överföringshastigheten och tidpunkten för leverans kan inte garanteras.Båda fallen utgör ett problem för OTP då idén bakom att använda USB kommunikation för denna realtidsapplikation var att få tillgång till hög överföringshastighet av mätdata som sedan kan analyseras. Att välja mellan att eventuellt få fel mätdata eller att få mätdata levererat för sent är inte en godtagbar kompromiss för denna tillämpning. Därför föreslår detta examensarbete att för fortsatt utveckling av OTP verktyget bör ett annat kommunikationsgränssnitt användas där dessa avvägningar inte behöver göras.
This thesis is part of a development which is to simplify the work of the prototyping of control systems. Embedded systems become more advanced and complex, thereby increasing the developer needs to easily and quickly get started with a first prototype. And to test, verify and debug directly on the prototype unit in addition to the traditional compiler and debuggmiljön. This development is called On Target Prototyping (OTP).One objective of this thesis was to develop hardware and related software to the developer. Communication but OTP platform and the PC was using the USB and XCP on USB. USB protocol has been part of the literature study was performed to investigate the feasibility of a faster communication than traditional serial communication. Unfortunately it turned out that the USB protocol was more complicated than was assumed when the thesis work started. In this application the OTP is required to send data via USB as close to real time as possible in order to be analyzed and presented in Caldesk. This presents a problem when the USB has only one Transfer Type, isochronous, which can handle larger amounts of data and that data will arrive on time. Unfortunately, this type of transfer is not possible without resending informs only that data packet contained errors. If you instead choose to give priority to the right data will be presented by the error control applied (bulk, control and interrupt) transfer rate drops and the time of delivery can not be guaranteed.Both cases pose a problem for OTP since the idea behind using USB communications for the real-time application was to obtain high throughput of experimental data which can then be analyzed. The choice to possibly get the wrong measurement or to obtain measurement data delivered too late is not an acceptable compromise for this application. Therefore, this thesis suggests that the continued development of the OTP tool uses a different communication interfaces where these considerations do not have to be made.

- Abstract
-
The need for additional research tools that allow for more extensive analysis exists in the field of Cable Suspended Robots (CSR) research. This system addresses that need by providing a hardware model as a type synthesis system that can be used to determine the possible designs, given a vast range of design specifications. This two part system was configured to be adaptable, transferable, and modular, allowing a workspace and trajectory validation and singularity analysis to be completed on an easy to use hand operated Subsystem #1. Offering visual and haptic feedback and potential control validation on Subsystem #2, which allows for a desired trajectory to be automated with easy to use microcontrollers and software program. The system was validated using two real-world CSR models, proving it can adequately represent a CSR. A prototype configuration was deployed onto the system, validation and trajectory results were positive; leading to the conclusion that this system is useful for type synthesis and prototyping of CSR configurations.
