The objective of this study has been to examine the portability of Moni- tor ERP System AB’s existing .NET Framework codebase to .NET Core. The study has been conducted by examining the portability of Monitor’s projects by using Microsoft’s .NET Portability Analyzer and visualizing the dependencies of projects by using AsmSpy to gain an understanding of what order projects need to be ported. An examination of used third-party libraries has also been conducted to see which libraries are not compatible with .NET Core. And an attempt to port Monitor’s root solution has been made as a proof-of-concept and to make test and build duration compar- isons between the ported solution and the old solution. The .NET Porta- bility Analyzer reported that 19 projects aren’t 100% compatible with .NET Core (+ Windows Compatibility Pack) where some projects have one miss- ing API call while others have many more. The third-party library examina- tion showed that two libraries are not compatible with .NET Core, the first is Dynamsoft Dynamic .NET TWAIN SDK which can probably be replaced with VintaSoft Twain .NET SDK, and SAP SQL Anywhere which doesn’t have a direct replacement. The results of the comparison show that test duration speeds improved on average by 22.5% with a peak of 67.6%, and build duration differences were negligible. Porting to .NET Core will not be easy, but if fixes for the 19 incompatible Monitor projects are completed and a replacement for SQL Anywhere can be found, then Monitor ERP System AB can make a successful port to .NET Core.

The number of users adopting cellular system technologies over the past years has been enormous. This rapid adoption is not comparable in any other technology. Additionally, this has meant that these users have (at least some of the time) the possibility of connectivity to others and to remote services (advanced data and voice services, such as video conferences, mobile TV, navigation, and location services). Increasingly there is no longer a clear boundary between the wide area cellular network and Internet services, as the wide area cellular network is evolving from circuit switched based technologies to an IP based system; hence these wide area cellular systems are simply becoming part of the Internet. This evolution has become a challenge for the telecommunication operators, who have been used to completely controlling their network services and billing. In an attempt to maintain this traditional role for telecommunication operators, telecommunication vendors have introduced the IP Multimedia Subsystem (IMS). A system designed to enable telecommunication operators to be able to bill the user for all of the different services accessed through the wide area cellular network. The goal of such a system is to prevent the telecommunication operators from becoming a "bit pipe" (i.e., simply providing "commodity priced" connectivity). Another relevant change that has direct impact upon this project is the role of mobile handsets as gateways between sensor networks and other networks (especially the wide area cellular networks or Internet). This has lead to integrated solutions, such as the smart house concept, mobile health monitoring, and others. This thesis project is a collaboration between Ericsson Research and SUUNTO, in which we have implemented a system for monitoring a user’s heart rate via IMS. The system (has a special focus on sports activities, but it could easily be adapted for health care) is based on internetworking sensor networks, specifically a heart rate belt that transmits data wirelessly, with the IMS network through a mobile phone or a PC. The implemented service runs on top of the SIP Presence service. This project examines two alternatives. The first is a mobile scenario, in which a person is jogging outdoors, in this setting the sensor node communicates via the person’s mobile phone, through the IMS network to a monitoring application. The second scenario is more fixed; such as a gym environment, where the sensor node communicates with a personal computer which in turn publishes the data via IMS. Once the data has been published to the Presence and group management sever, an application server subscribed to the athlete’s Presence service will be notified. The people interested in viewing this data will be able to see it through any web-browser. It will even be possible to archive, and download the data for later use by other applications. The system is not optimized yet for a truly real-time communication, as the Presence service does not offer this as other technologies (RTP, SRTP or XMPP) do. There is a big delay difference between the mobile and the fixed solution. We can say that the fixed solution is almost a real-time system for transmitting low frequency data as heart rate information. This project is a first approach to a final high performance system. / Antalet användare som har fått tillgång till mobiltelefon under de senaste åren har varit enorm. Detta snabbt antagande är inte jämförbar med någon annan teknik. Dessutom innebär också detta att dessa användare har (åtminstone ibland) möjligheten till anslutning till andra och till avlägsna tjänster (avancerad data-och taltjänster, t.ex. videokonferenser, mobil TV, navigation och lokaliseringstjänster). Idags läget finns det inte längre en tydlig gräns mellan cellulära nätet och Internettjänster. Efter cellulära nätets utveckling från kretskopplad teknik till ett IP-baserat system, så håller dom cellulära systemem på att bli en del av Internet. Denna utveckling har blivit en utmaning för telekommunikationsföretag, som har varit vana att helt kontrollera sina nättjänster och fakturering. I ett försök att bevara denna traditionella roll för telekommunikationsföretag, har telekom-leverantörer infört IP Multimedia Subsystem (IMS). Ett system som syftar på att kunna göra telekommunikationsföretagen kapabla till att debitera användaren för alla dem olika tjänsterna som han har tillgång till via deras cellulära nät. Målet med ett sådant system är att förhindra telekommunikationsföretagen från att bli en "bit pipe" (dvs bara ge prissatt konnektivitet). En annan betydelsefull förändring som har direkt inverkan på detta projekt är den roll som mobiltelefoner kan utföra som gateways mellan sensornätverk och cellulära nät eller Internet. Detta har påverkat flera integrerade lösningar, såsom smarta hus begrepp, mobil hälsoövervakning och andra. Denna examensarbetes projekt är ett samarbete mellan Ericsson Research och Suunto, där vi har implementerat ett system för övervakning av en användares hjärtslag genom IMS. Systemet (har en särskild inriktning på sport, men det kan lätt anpassas för hälso-och sjukvård) är baserad på Internetworking sensornätverk, särskilt en hjärtfrekvens bälte som överför data trådlöst till en mobiltelefon eller en dator, som sedan skickar ut datan via IMS-nätverket. Tjänsten genomförs ovan på SIP Presence service. Projektet undersöker två alternativ. Den första är en mobil scenario; exempelvis där en person joggar utomhus, vid ett sådant tillfälle kommunicerar sensorn noden genom personens mobiltelefon, via IMS-nätverk med en övervaknings application. Det andra scenariot är mer statiskt och ger inte samma rörlighet, denna lösning passar bättre in på gym activiteter eller liknande. I denna implementering kommunicerar sensorn noden med en persondator som i sin tur publicerar uppgifterna via IMS. När uppgifterna har publicerats hos Presence and group management (PGM) servern. En applikations server som är uppskriven på att få friidrottarens närvaro tjänst kommer att meddelas. De människor som intresserade av att se denna data kommer att kunna göra det via någon webbläsare. Det kommer även att vara möjligt att arkivera och hämta datan för senare en användning men andra tillämpningar. Systemet är inte optimerad ännu för en verkligt realtid, eftersom Presence service inte erbjuder detta ännu som andra tekniker (RTP, SRTP eller XMPP) gör. Det finns en stor fördröjning skillnad mellan den mobila och fasta lösningen. Vi kan säga att den fasta lösningen är nästan ett realtids-system för överföring av lågfrekventa uppgifter som hjärtslag information. Detta projekt är en första strategi för en slutlig högpresterande system.

Norden Machinery AB i Kalmar är idag en ledande leverantör inom högpresterande tubfyllingssystem. Dessa är mestadels automatiska, men när det gäller förpackning finns det några arbetsmoment som utförs manuellt. Detta gör att de ergonomiska aspekterna kring dessa arbetsmoment måste prioriteras högt. I den nuvarande situationen utgör panelarmen som håller fast maskinens kontrollpanel ett ergonomiskt problem då den varken går att höja eller sänka. Syftet med projektet är att tillsammans med Norden utveckla en ergonomisk och användarvänlig lösning gällande panelarmen vid tubfyllningsmaskinerna. Frågeställningen behandlar hur detta görs genom att integrera design för ergonomi, flexibilitet och moduläritet i designprocessen. För att uppfylla syftet och frågeställningen med arbetet användes den grundläggande produktutvecklingsprocessen som Ulrich och Eppinger (2012) har tagit fram. Processen utgår från en förstudie där kraven på produkten sammanställs i en kravspecifikation och att designproblemet delas upp i mindre delproblem. Med detta som grund genereras koncept som därefter utvärderas mot kravspecifikationen vilket slutligen resulterar i att ett koncept väljs ut för vidareutveckling. Till dessa steg har teori och verktyg kring ergonomi, flexibilitet och moduläritet implementerats. Den slutgiltiga lösningen utgörs av modulära komponenter och är betydligt mer ergonomisk och användarvänlig än Nordens nuvarande konstruktion. Lyftanordningen består av en parallellogram och en gasfjäder omslutna av ett par balkar. Detta ger den lyftfunktion som krävs för att konstruktionen ska kunna hålla skärmen på plats och dessutom erbjuda höj- och sänkbarhet. Båda fästena gjordes i princip identiska och baserades på fästena hos Nordens nuvarande lösning. På så sätt behöver inga nya fästpunkter konstrueras och kostnaden kan hållas nere. Överlag förväntas konstruktionen uppnå de förväntningar och mål som både vi och Norden har. Den ergonomiska designaspekten passade bäst in vid förstudien, vilket beror mycket på att teorin kring ergonomi har sin grund i de regler, riktlinjer och mål som berör slutprodukten. Moduläriteten bidrog till att mer detaljerade koncept kunde skapas tack vare problem-uppdelningen. Flexibiliteten var inte fullt lika användbar men gav bra understöd till moduläriteten under processens gång. Huvudsaken är att vid en implementering likt denna ta hänsyn till eventuella kompromisser som kan behöva göras, och att alltid ha slutmålet med projektet i åtanke. / Norden Machinery AB in Kalmar is today a leading supplier of high performance tubing systems. These are mostly automated, but in the case of packaging, there are some operations that are performed manually. This means that the ergonomic aspects of these operations must be given high priority. In the present situation, the panel arm that holds the machine's control panel constitutes an ergonomic problem as it cannot be raised or lowered. The purpose of the project is to develop an ergonomic and user-friendly solution for the panel arm at the tube filling machines together with Norden. The thesis question addresses how this is done by integrating design for ergonomics, flexibility and modularity in the design process. In order to fulfil the thesis question and the purpose of the work, the generic product development process developed by Ulrich and Eppinger (2012) was used. The process is based on a preliminary study where the needs and requirements of the product are compiled in a requirement specification, and where the design problem is divided into sub-problems. With this in mind, it is possible to generate concepts. These are then evaluated against the specification which results in a concept being chosen for further development. During this process, theory regarding ergonomics, flexibility and modularity have been implemented. The final solution consists of modular components and is considerably more ergonomic and user-friendly than Norden’s current design. The lifting device consists of a parallelogram and a gas spring enclosed by a pair of beams. This provides the lifting function required for the design to keep the screen in place and offer raising and lowering possibilities. The screen- and machine attachment were based on Norden’s current design. This means that there is no need to construct new attachment points and the cost can be kept down. Overall, the design is expected to achieve the expectations and goals that both we and Norden have. Design for ergonomics were best suited for implementation at the preliminary study, since it is based on the rules, guidelines and goals that concern the final product. Modularity contributed to the creation of more detailed concepts due to the sub-problems. Flexibility was not quite as useful but gave good support to modularity during the process. The main thing is to consider any compromises that may need to be made in an implementation like this, and to always have the final goal of the project in mind.

La réduction des marges temporelles dans les circuits synchrones est une manière d'améliorer leur performance.En cas de vieillissement, de fluctuations de la tension d'alimentation ou de la température du milieu de mission, des réductions sévères des marges temporelles peuvent néanmoins avoir un impact négatif sur la fiabilité des circuits. La réduction des marges temporelles sans dégradation de la fiabilité peut être réalisée à l'aide des informations d'un contrôle en ligne de ces marges. Cette thèse porte sur l'étude du suivi en ligne des marges temporelles des circuits intégrés synchrones. La première contribution de ce travail consiste en une nouvelle solution shadow-scan bien adaptée au suivi en ligne des marges temporelles, permettant une mise en œuvre de bascules scan plus rapides et pouvant être gérées de façon transparente par les outils de conception du commerce. Une approche naturelle de mise en œuvre du suivi des marges temporelles est le déploiement de moniteurs sur tous les chemins critiques ou susceptibles de le devenir à cause du vieillissement ou des variations dues au processus de production.Dans des circuits très contraints en termes de temps de propagation, avec un grand nombre de chemins critiques, cette approche peut conduire à un surcoût en surface trop important pour un gain en performance limité. Afin de pouvoir réduire le nombre de moniteurs avec un impact limité sur la qualité du monitoring, la seconde contribution de ce travail est la proposition d'une nouvelle méthode d'évaluation de la qualité du monitoring d'un groupe de bascules.Cette méthode est basée sur l'estimation de la probabilité d'activation des moniteurs. Deux métriques sont proposées pour quantifier la qualité du suivi des marges temporelles. La première sert à estimer la couverture temporelle d'un groupe de bascules, alors que la deuxième permet d'évaluer la couverture spatiale.Enfin, en se basant sur ces deux métriques, la dernière contribution de ce travail est la démonstration du fait qu'il est possible avec un surcoût limité d'améliorer significativement la qualité du monitoring d'un circuit si les moniteurs sont adaptés aux cônes logiques qu'ils surveillent. / Slack-time reduction is a way to improve the performance of synchronous sequential circuits. In the presence of circuit wear-out, supply voltage fluctuations and temperature variations, aggressive slack-time reduction can be achieved based on adaptive voltage and frequency scaling with feedback from in-situ slack-time monitoring. The first contribution of this work consist of a new shadow-scan solution which facilitates the implementation of faster scan Flip-Flops (FFs), enables in-situ slack-time monitoring and can be transparently handled by commercial tools for automated scan stitching and automated test pattern generation. A natural approach is to place in-situ slack-time monitors close to all sequential elements with incoming timing-critical paths or susceptible to become timing-critical due to wear-out or manufacturing variability. In latency-constrained circuits with large ratios of timing-critical paths, this methodology may result in large area overheads and minor power improvements. The second contribution of this work is an evaluation methodology of the monitoring quality delivered by a set of FFs. This methodology estimates monitor activation probabilities based on which two evaluation metrics are provided. On one hand, the expected ratio of clock cycles with at least one monitor activated can be used to estimate the temporal coverage of the in-situ slack-time monitoring scheme. On the other hand, the expected number of activated monitors per clock cycle can be used to evaluate the spatial coverage of the monitoring scheme. Finally, based on these metrics, it is shown that the monitoring quality can be significantly improved if the size of the detection window of each in-situ slack-time monitor is correlated to the slack-time of the monitored timing-critical paths.

abstract: Most studies that explored the health benefits of interrupting sitting time focused on using different modalities (i.e., comparing walking vs standing breaks)33,36,59. However, experimental studies that directly compare patterns of interrupting sitting time through standing only are needed to advance the field. This study aimed to (i) determine if there is a difference in glucose response between continuous sitting (CS) and two intermittent standing regimes (high frequency, low duration breaks (HFLD) and low frequency, high duration breaks (LFHD)) and (ii) to determine if there is a difference in glucose response between the two strategies (HFLD vs. LFHD). Ten sedentary employees (mean±SD age 46.8±10.6 years; 70% female) with impaired fasting glucose (mean glucose= 109.0±9.8 mg/dL) participated. Eligible participants were invited to three 7.5 hour laboratory visits where they were randomized to perform each study conditions: (i) CS, (ii) HFLD and (iii) LFHD. Standardized meals (breakfast and lunch) were given with each meal providing 33% of the participant’s total daily caloric needs following a typical American diet (50-60% carbohydrates, 25-30% fat, and 10-20% protein). Participants wore an activPAL device to measure compliance with the sit-stand condition and a continuous glucose monitor to measure post-prandial glucose response. Post-prandial mean glucose, incremental area under the curve and mean amplitude glycemic excursion between conditions were evaluated using linear mixed models. Participants demonstrated high compliance with the study condition. The results indicated that the mean glucose of the HFLD condition were significantly lower (p< .01) than the CS condition with mean difference of -7.70 (-11.98, -3.42) mg/dL·3.5h and -5.76 (-9.50, -2.03) mg/dL·7h for lunch and total time, respectively. Furthermore, the mean post-prandial glucose during lunch and total time were significantly lower in the HFLD condition compared to the LFHD condition with mean difference of -9.94 (-14.13, -5.74) mg/dL·3.5h and -6.23 (-9.93, -2.52) mg/dL·7h, respectively. No differences were found between the CS and LFHD conditions. This study provides evidence favoring the use of frequent interruptions in sitting time to improve glycemic control of prediabetic individuals. In contrast, less frequent, although longer bouts of standing resulted in similar post-prandial glucose profile to that of the continuous sitting condition despite total standing time being equal to the LFHD condition. / Dissertation/Thesis / Doctoral Dissertation Physical Activity, Nutrition and Wellness 2019

For future multicores, a dedicated interconnect subsystem for on-chip monitors was found to be highly beneficial in terms of scalability, performance and area. In this thesis, such a monitor network (MNoC) is used for multicores to support selective error identification and recovery and maintain target chip reliability in the context of dynamic voltage and frequency scaling (DVFS). A selective shared memory multiprocessor recovery is performed using MNoC in which, when an error is detected, only the group of processors sharing an application with the affected processors are recovered. Although the use of DVFS in contemporary multicores provides significant protection from unpredictable thermal events, a potential side effect can be an increased processor exposure to soft errors. To address this issue, a flexible fault prevention and recovery mechanism has been developed to selectively enable a small amount of per-core dual modular redundancy (DMR) in response to increased vulnerability, as measured by the processor architectural vulnerability factor (AVF). Our new algorithm for DMR deployment aims to provide a stable effective soft error rate (SER) by using DMR in response to DVFS caused by thermal events. The algorithm is implemented in real-time on the multicore using MNoC and controller which evaluates thermal information and multicore performance statistics in addition to error information. DVFS experiments with a multicore simulator using standard benchmarks show an average 6% improvement in overall power consumption and a stable SER by using selective DMR versus continuous DMR deployment.

Die natürliche Umgebungsluft enthält Aerosolpartikel, deren Größe von wenigen Nanometern bis zu einigen Mikrometern reicht. Insbesondere anthropogenen ultrafeinen Partikeln, die kleiner als 100 nm sind, werden negative Wirkungen auf die menschliche Gesundheit zugeschrieben. Die gravimetrische Messung der Partikelmassekonzentration erfasst ultrafeine Partikel nur ungenügend, da die Masse dieser Partikel sehr gering ist. Deutlich empfindlicher gelingt die Quantifizierung ultrafeiner Partikel durch die Messung der Partikelanzahlkonzentration. Die Arbeit beschreibt ein Verfahren zur Messung der Anzahlkonzentration von Partikeln in Umweltaerosolen. Es verknüpft die elektrische Aufladung der Partikel mit deren Klassierung im elektrischen Feld und ihre Mengenbestimmung anhand der elektrischen Ladung. Mittels des entwickelten Sensormodells gelingt die Verbindung der gemessenen Rohdaten mit der Anzahlgrößenverteilung der Partikel durch eine Kernfunktion in einer Fredholmschen Integralgleichung erster Art. Zur Dateninversion wird diese Gleichung in diskreter Form als lineares Gleichungssystem genutzt. Dessen Koeffizienten bilden die Kernmatrix, welche mit einer neu entwickelten Methode experimentell bestimmt wird. Vergleichsmessungen zeigen eine gute Übereinstimmung des Verfahrens mit Referenzverfahren der Aerosolmesstechnik und unterstreichen die Eignung des Verfahrens zur Partikelquantifizierung in Umweltmessnetzen.
