Thesis: S.B., Massachusetts Institute of Technology, Department of Mechanical Engineering, 2018.<br>Cataloged from PDF version of thesis.<br>Includes bibliographical references (page 31).<br>Foot contact forces are imperative to gait analysis for uses such as elderly rehabilitation and athletic training. Previously developed methods for legged locomotion force detection involved convoluted sensing systems and significant external equipment. This thesis builds upon previous developed smart shoe sensors adapted from the MIT Cheetah robot using pressure sensors embedded in urethane rubber, Smooth-On's Vytaflex® 20. Past work developed accurate material models in Abaqus CAE to simulate foot contacts for compression and shear. This thesis builds upon the FEA models for two sensor sizes to create a simple model to measure torque and contact angle given force measured by the sensor. Using experiments with physical footpads on a CNC mill verified by simulations from Abaqus FEA, we derived models for contact angles between 0 to 15 degrees and rolling movement from -7 to 7 degrees at various compressions. Models successfully derive relationships between roll and contact angle versus force. These models can be used as a jumping point for data analysis using the smart shoe sensor.<br>by Jingya (Lauren) Luo.<br>S.B.

Full textAbstract:
This thesis deals with a new marketing tool for campaigns to support product sales at the point of sales. Banner can appropriately draw customer's attention and also persuade to unplanned impulsive purchase. It is a plastic pocket that can hold posters to support individual product or brands of companies and also can be changed quite often. Uniqueness of the solution lies in the location of the advertising space. In case an LCD monitor is part of the cash register, the banner is located on the other side directly exposed to the eyes of customers. The aim of the thesis is to present a new marketing tool and ideally prove that the right use of visual communication means is able to encourage impulsive purchases even in the environment of a Czech bank. Even though it was not completely proven that the banner can encourage impulsive purchases in banks, the whole concept has been prepared, it's potential revealed and the possible effective uses for normal practice have been formulated.

Full textAbstract:
The potential of Digital twin (DT) technology outside of the industrial field has been recognized by researchers who have promoted the vision of applying DTs technology beyond manufacturing, to purposes such as enhancing human well-being and improving quality of life (QoL). The expanded definition of DTs to incorporate living and nonliving physical entities into the definition of DTs was a key motivation behind the model introduced in this thesis for building health digital twins of citizens. In contrast with DTs that have been developed in more industrial fields, this type of digital twins modeling necessitates protecting each citizen's unique identity while also representing features common to all citizens in a unified way. In nature, DNA is an example of a model that is both unified, common to all humans, and unique, distinguishing each human as an individual. DNA’s architecture is what inspired us to propose a digital twin DNA (DT-DNA) model as the basis for building health DTs for citizens. A review of the literature shows that no unified model for citizens’ health has been developed that can act as a base for building digital twins of citizens while also protecting their unique identity thus we aim to fill this gap in this research. Accordingly, in this thesis, we proposed a DT-DNA model, which is specifically designed to protect the unique identity of each citizen’s digital twin, similar to what DNA does for each human. We also proposed a DT-DNA-based framework to build standardized health digital twins of citizens on micro, meso and macro levels using two ISO standards: ISO/IEEE 11073 (X73) and ISO 37120. To achieve our goal, we started by analyzing the biological DNA model and the influencing factors shaping health in smart cities. The purpose of the first is to highlight the DNA model features which provide the building blocks for our DT-DNA model. The purpose of the latter is to determine the main bases of our DT-DNA model of health DTs. Based on the analysis results; we proposed DT-DNA to model health DTs for citizens. In keeping with our DNA analogy, we have identified four bases, A, T, G, and C, for our unified and unique DT-DNA model. The A base in the proposed model represents a citizen’s anthropometric when we build the DT-DNA on an individual level and represents the city’s regulatory authorities when we build the DT-DNA on community and city levels. The T base represents different tasks included in the provided health data that are required to model citizens’ health DT-DNA on different levels. The G base represents the geographic and temporal information of the city, where the citizen exists at the time of data collection. The C base represents the context at the time of data collection. To proof the concept, we present our initial work on building health DTs for citizens in four case studies. The first two case studies are dedicated for health DTs at the micro level, the third case study is dedicated for health DTs at the meso level and the fourth case study is dedicated for health DTs at the macro level. In addition, we developed an algorithm to compare cities in terms of their community fitness and health services status. The four case studies provide promising results in terms of applicability of the proposed DT-DNA model and framework in handling the health data of citizens, communities and cities, collected through various sources, and presenting them in a standardized, unique model.

Projektet beskriver ett tillvägagångssätt för att alstra energi genom solceller och piezoelektronik. Ett kretskortsbaserat system designades som utnyttjade superkondensatorer som lagringsenhet. Planen var att integrera systemet i en sko. Genom denna teknik kan man då substituera eller minimera batteriladdningen för smarta enheter eller mindre anordningar. Det önskvärda resultatet med projektet var att se om det gick att koppla detta system till en mikrokontroller som kunde drivas på låg spänning. Rapporten fick ett positivt resultat med en konstant utspänning på 1.8 volt som kunde driva en mikrokontroller. Dock tog det lång tid för superkondensatorerna att laddas upp på grund av den impedans som fanns i systemet. Aktiviteter som utnyttjar detta system kommer att påverka uppladdningens resultat. Detta gör kretsen optimal för aktiviteter som involverar rörelse och sol, såsom hiking.<br>The past couple of decades gave rise to smartphones, smart watches, and smart homes. Now researchers are looking for ways to make smart clothing. One use case of smart clothing is smart shoes which can give some very useful sensed information especially in the sports industry and healthcare. Such sensed data include temperature, distance and calories, fall detection and many more. This application scenario can be designed to be battery free if we make use of the human motion and solar power. Many research papers exist which present how to exploit swing and shock excitations from the shoes to harvest energy. In this project this energy combined with solar energy will be used to power a low driven MCU. I design a pcb which include solar panels and piezoelectric modules to store the energy in supercapacitors. The goal is to integrate this pcb in a shoe, meaning that it has to have a small size and low power. The results of the project showed that a constant voltage at 1.8 volt could be achieved however recharge time is a factor to take into consideration. The system showed positive results for activities including movements and sun such as hiking.

Full textAbstract:
Introduction The paradigm shift in manufacturing that Industry 4.0 brings forth with new advanced technologies and the rapid growth of sensing and controlling technologies enable further visualization and optimization that can contribute to achievingimproved decision-making in manufacturing. A significant new capability is the ability to construct a Digital Twinthat connects the physical and virtual space. However, there are still confusion and obscurity regarding what Digital Twinis and how it can becreated and then used to create value for the company. Therefor the purpose of the thesis is to examine how manufacturing companies can utilize the implementation of Digital Twinand assess Digital Twinin a shop-floor. ➢RQ1: How can DT be beneficial to increase business value in a manufacturing company? ➢RQ2: What changes need to be done in the shop-floor to implement Digital Twin? Methodology A literature review was conducted to provide previous researchand contextwithin the area of Digital Twin. A multiple-case studywas performed at three case companies to gain meaningful insight from a real-world perspective, semi-structured interviews, dialogs, and observations were conductedat the case companies. The analysis was then performed by examining similarities, and dissimilarities between theoretical and empirical data, as well as opportunities in theoretical findings that correspond with challenges in empirical findings. Frame of Reference The literature review increased the authors’ understanding of the research topic and gave context to the concept of Digital Twin. The review is mainly focused on the Digital Twintechnologyand how it is constructed, as well as the applicationsareas. Empirical Findings The empirical findings provide an overview of boththe current and future state of the case companies in relation to organizational, operational, and technological factors. Additionally, it provides a deeper understanding of how shop-floor management is designed at one of the case companies. Analysis The combination of the Frame of Reference and Empirical Findings contributewith important insight on the potential benefits that can be created through the utilizationof Digital Twin, as well as what is requiredin the shop-floor to enable implementation ofDigital Twin. Conclusions The value that can be created utilizing Digital Twinis outlinedand a clearer definition is proposed to avoid misunderstandings and confusion. Requirements that need to be achieved for a successful implementation arecovered as well. A future recommendation is measuring resources and effort in relation to the created value of a Digital Twin.

Full textAbstract:
The enormous growth of the Internet and the World Wide Web has provided the opportunity for an enterprise to extend its boundaries in the global business environment. While commercial functions can be shared among a variety of
strategic allies - including business partners and customers, extranets appear to be
the cost-effective solution to providing global connectivity for different user groups.
Because extranets allow third-party users into corporate networks, they need to be extremely secure and external access needs to be highly controllable. Access control and authorisation mechanisms must be in place to regulate user access to information/resources in a manner that is consistent with the current set of policies
and practices both at intra-organisational and cross-organisational levels.
In the business-to-customer (B2C) e-commerce setting, a service provider faces a wide spectrum of new customers, who may not have pre-existing relationships established. Thus the authorisation problem is particularly complex. In this thesis, a new authorisation scheme is proposed to facilitate the service provider to
establish trust with potential customers, grant access privileges to legitimate users and enforce access control in a diversified commercial environment. Four modules with a number of innovative components and mechanisms suitable for distributed authorisation on extranets are developed:
* One-shot Authorisation Module - One-shot authorisation token is designed as a flexible and secure credential for access control enforcement in client/server systems;
* Token-Based Trust Establishment Module - Trust token is proposed for server-centric trust establishment in virtual enterprise environment.
* User-Centric Anonymous Authorisation Module - One-task authorisation key and anonymous attribute certificate are developed for anonymous
authorisation in a multi-organisational setting;
* Agent-Based Privilege Negotiation Module - Privilege negotiation agents are proposed to provide dynamic authorisation services with secure client agent environment for hosting these agents on user's platform

Cette thèse vise à déterminer l’influence de deux traitements mécaniques, le grenaillage SMAT effectué avec plusieurs types de billes (en WC, en alumine et en verre) et le choc laser, sur la résistance à l’oxydation haute température de deux alliages de titane : un alliage alpha commercialement « pur » (Grade 1) et un alliage aéronautique béta métastable (TIMETAL-21S).Une fois traitées, les pièces sont oxydées avec différentes conditions : de durée (entre 5 heures pour étudier les premier instants de l’oxydation et 3000h pour se rapprocher d’un essai type en aéronautique), de température (600°C à 700°C) et d’atmosphère (air sec et oxygène).Les pièces sont analysées avant et après oxydation à l’aide de plusieurs techniques d’analyses : mécaniques (dureté, mesures de contraintes), chimiques (DRX, microsonde nucléaire, …) ou structurales (EBSD, texture).Les résultats obtenus montrent que les traitements perturbent fortement les pièces avant leur exposition à haute température d’un point de vue morphologique, structural, mécanique et chimique. Ces traitements mécaniques amènent une réduction de l’oxydation des pièces étudiées. Il semble qu’ils modifient la vitesse de diffusion des espèces (azote, oxygène, aluminium, molybdène) mais aussi la microstructure (recristallisation, morphologie de grain ou texturation) au cours de la mise en température. L’azote joue un rôle essentiel dans les phénomènes observés.Néanmoins, la détermination des conséquences de ces traitements sur la résistance à l’oxydation reste encore complexe de par les observations de ce travail, qui révèlent une contribution simultanée de plusieurs facteurs : chimiques, mécaniques et structuraux<br>The aim of this thesis is to determine the influence of two mechanical surface treatments, the shot- peening performed with several type of balls (WC, alumina and glass) and the laser shock peening, on the high temperature oxidation resistance of two titanium alloys : alpha alloy with commercially purity (Grade 1) and aeronautical beta metastable alloy (TIMETAL-21S).After different treatments, the pieces are oxidized with different conditions: of time (between 5 hours to study the firsts times of oxidation and 3000 hours to compare with a classical aeronautical test), of temperature (600°C to 700°C) and atmosphere (dry air or oxygen).The pieces are analyzed before and after oxidation exposure with several mechanical (micro-hardness, strain measurements), chemicals (XRD, nuclear microprobe) and structural (EBSD, texture) techniques. The results show a large surface perturbation before the high temperature exposure in term of morphological, mechanical, structural and chemical point of view.This mechanical treatments lead up to an oxidation rate reduction for all the different titanium alloys. This treatments modified the diffusion rate of several elements (nitrogen, oxygen, molybdenum or aluminum) but also the microstructure (recrystallization, grain morphology or texturing) during high temperature exposure. Nitrogen element plays an important role in the observed phenomena.However, the determination of consequences after mechanical treatment on the titanium oxidation resistance is again difficult with the observations noted in this work. Actually, there is a simultaneous contributions of several factors: chemical, mechanical and structural

Full textAbstract:
Les effets du SMAT sur les propriétés en fatigue uniaxiale et en torsion ont été étudiés pour un alliage d'aluminium 7075. Des éprouvettes de fatigue ont été traitées thermiquement pour augmenter la sensibilité du matériau au SMAT. Certaines propriétés de cet alliage traité par SMAT ont été caractérisées par des essais de traction et de microdureté. Par rapport à l'état brut d'usinage (AM), les durées de vie en fatigue uniaxiale des éprouvettes SMATées (AM-SMAT) sont augmentées pour des amplitudes de contrainte élevées, mais diminuées pour de faibles amplitudes. Cependant, pour les éprouvettes traitées thermiquement (HT), leurs durées de vie après SMAT (HT-SMAT) sont augmentées pour toute la gamme de contraintes étudiée. Des phénomènes similaires ont été observés pour les éprouvettes testées en fatigue sous sollicitations en torsion. D'autres analyses ont été effectuées pour étudier la dispersion des données de fatigue avec une approche statistique. Les mécanismes de fissuration ont été analysés à l’aide d’observations des éprouvettes rompues. Il a été mis en évidence que les mécanismes sont différents pour les éprouvettes présentant différents états et qu'ils dépendent également du niveau de contrainte imposée. En se basant sur ces résultats, les effets bénéfiques et néfastes du traitement SMAT ont été analysés. Le rôle joué par différents facteurs comme les contraintes résiduelles, le raffinement des grains et la rugosité de surface, a été examiné pour la fatigue sous sollicitations uniaxiales et en torsion<br>The effects of SMAT on uniaxial and torsional fatigue properties were investigated for a 7075 aluminium alloy. A part of fatigue specimens was heat treated to increase the sensitivity of the material to SMAT represented by its ductility. Basic properties of the alloy in different states treated by SMAT were characterized through tensile tests and microhardness measurements. Compared to as-machined (AM) state, the fatigue lives of SMATed specimens (AM-SMAT) tested under uniaxial loading were increased under high stress amplitudes, but decreased under low amplitudes. However, the fatigue lives of SMATed specimens (HT-SMAT) were increased under all the studied stress amplitudes, with respect to heat treated (HT) state. Similar phenomena were observed for the specimens tested under torsional fatigue. Further analyses were performed to investigate the scatter of fatigue data using a statistical approach. The cracking mechanisms of specimens in different states were analysed through observations of failed specimens. It was revealed that the mechanisms are different for specimens in different states and that they are dependent on the imposed stress levels. Based on these results, both beneficial and detrimental effects exhibited by SMAT were analysed. For this purpose, the role played by various factors including residual stresses, grain refinement and surface roughness, were discussed for both uniaxial and torsional fatigue

Les effets du SMAT (Surface Mechanical Attrition Treatment) sur les propriétés en fatigue d’un alliage CoCrMo ont été étudiés par des essais en flexion rotative. Des éprouvettes de fatigue ont été traitées par SMAT avec différentes tailles de billes (SMAT-2 et SMAT-3). La microstructure, l'intégrité de surface et la microdureté ont été caractérisées. Les essais de fatigue ont montré que le SMAT-2 générait des durées de vie plus élevées par rapport aux conditions brut d’usinage (AM) et SMAT-3. Le SMAT-2 a amélioré l'intégrité de surface, tandis que le SMAT-3 l'a détériorée en raison d'un sur-grenaillage. La résistance à la fatigue à 107 cycles a été caractérisée pour les conditions SMAT-2 et AM. Les mécanismes de fissuration ont été analysés par fractographie. Presque toutes les éprouvettes SMAT-3 et AM se sont rompues à partir de la surface, tandis que pour le SMAT-2, la fissuration a été initiée en interne, sous forme de fish-eye. L'efficacité du SMAT-2 contre une fissuration initiée en surface a été prouvée. Au centre des zones en fish-eyes, les facettes principales ont généralement été identifiées comme des sites d'initiation de fissures. La surface des fish-eyes a été mesurée afin d'estimer les facteurs d'intensité de contrainte et de prédire la durée de vie en fatigue. Certains facteurs importants comme le gradient de propriétés, les contraintes résiduelles et leur relaxation, une transformation éventuelle de phases ont également été pris en compte qualitativement dans l'analyse du processus complexe de fissuration<br>The effects of SMAT (Surface Mechanical Attrition Treatment) on rotating bending fatigue properties were investigated for a CoCrMo alloy. Some fatigue specimens were processed by SMAT with different ball sizes (named SMAT-2 and SMAT-3). Microstructure, surface integrity and microhardness were characterized before and after SMAT. Fatigue tests showed that SMAT-2 presented higher fatigue life, compared to As-machined (AM) and SMAT-3 specimens. SMAT-2 actually improved surface integrity, while SMAT-3 deteriorated it by introducing surface defects due to over-peening. Fatigue strength at 107 cycles and scatter were obtained for SMAT-2 and AM groups. The cracking mechanisms of all specimens were analysed through fractography. It was revealed that almost all SMAT-3 and AM specimens fractured because of surface crack initiation, while SMAT-2 induced sub-surface cracks in form of fish-eye for most specimens. It proved the efficiency of SMAT-2 against surface originating cracks. At the centre of fish-eyes, main facets were generally identified as crack initiation sites. The areas of fish-eye zones obtained at different stress levels were measured in order to estimate stress intensity factor at crack tip and predict fatigue life. Some important factors including gradient properties, residual stress and its relaxation, phase transformation were also qualitatively taken into account in the analysis of the complex cracking process

La pandemia di COVID-19 sarà senza dubbio ricordata come un evento spartiacque nella storia mondiale, che ha avuto un innegabile impatto su diversi aspetti della vita quotidiana e su diversi settori produttivi. Anche l'industria televisiva ha subito gli effetti della pandemia, e nel corso dei mesi si è dovuta più volte adattare alla situazione in costante sviluppo. Con questa tesi si intende analizzare l'impatto della pandemia di COVID-19 su questo settore, offrendo una panoramica delle difficoltà affrontate dalle diverse categorie di programmi durante l'emergenza sanitaria e le tipologie di soluzioni adottate.
Nella prima parte si analizzeranno gli effetti immediati dell'interruzione delle attività lavorative e sociali e il confinamento in casa, quali i cambiamenti nei livelli di ascolti o nei numeri di abbonati a piattaforme streaming. Si rifletterà inoltre sulla centralità della televisione in questo periodo e sulle modalità con cui diversi programmi hanno continuato la produzione a distanza o sono stati creati da zero nell'ottica del distanziamento sociale. Nella seconda parte si analizzerà la graduale ripresa delle normali attività produttive e il modo in cui la realtà della pandemia è stata affrontata serie scripted, oltre alle misure di sicurezza adottate nella ripresa di programmi unscripted. Nella terza parte si prenderanno in considerazione i cambiamenti nella produzione, la distribuzione e il consumo che si sono verificati durante l'emergenza sanitaria e si tenterà di capire in base alle opinioni di studiosi e professionisti del settore quali tra questi saranno con buone probabilità permanenti e cosa questo potrebbe comportare a medio-lungo termine. Nell'ultima parte, infine, si prenderà in considerazione il caso specifico del talk show Che tempo che fa e si analizzeranno le modifiche da esso messe in atto durante i mesi di emergenza, tanto dal punto di vista produttivo quanto da quello dei contenuti.

Industri 4.0 har medfört stora förändringar och med denna våg av förändringar har artificiell intelligens tillkommit. AI är inget nytt och har forskats på utvecklats sedan den första datorn uppfanns. Tanken var då enligt Alan Turing fadern av datalogi att om en maskin inte kan särskiljas från en människa då är det en AI. Sedan dess har vi sett flera AI modeller slå människan i olika fält och sett AI teknologiers förmåga. Att AI ska implementeras inom den mest innovativa branschen var inte långtsökt. Industriell AI är till skillnad från vanliga AI modeller en kontrollerad process som hittills tillämpats inom begränsade områden. Eftersom standardisering och systematisk tillvägagångsätt kan likställas som synonymer till industriella verksamheter. Är det ingen skillnad på processer inom fabriker, och AI teknologier måste anpassas efter dessa processer. Det har under det senaste decenniet globalt investerats i innovation inom industrier. Länder världen över vill att deras industrier med Industri 4.0 hamnar i framkanten. Där Tyskland introducerade Industri 4.0, USA Smart Manufacturing Leadership Coalition, Kina deras plan kallad China 2025 och EU tillkännagett Factories for the future. Som en konsekvens av dessa enorma satsningar har denna studie som mål att se hur AI kan hjälpa tillverkande företag öka resurseffektiviteten inom produktionsplanering. Eftersom forskningsområdet är relativt nytt kommer studien basera resultaten på fallstudier där ABB och Scania intervjuas. Dock behöver detta område mer forskning.<br>The global introduction of Industry 4.0 has brought with it changes within industry. The indirect consequence of Industry 4.0 being artificial intelligence. The idea of AI is as old as the invention of computers with Alan Turing the father of computer science stating the first description of AI. His thought was that if a machine could be mistaken for a human then the machine was intelligent. The thought being that machine never could outperform humans back then. Now in modern times we have witnessed great feats made by intelligent algorithms where they outperform humans in various fields. For AI to be implemented in industry the most innovative buisness it has to adapt to the workings of indutrial processes. Systematic approach and standardization being two values that strongly represents industries. During the last decade global initiative and investment in innovation of industry. Has led to global competitors such as Germany creating Industry 4.0, The United States creating Smart Manufacturing Leadership Coalition, China introducing their plan called China 2025 and EU with Factories for the future. This paper is a reaction of these enormous investments made into Industry 4.0. The objective of this paper is to examine how AI can help manufacturing enterprises increase their resource efficiency within production planning. Since this field of science stillbeing in its infancy this paper will base its result on interviews made with companies as ABB and Scania. However this field needs more work.

Ce travail de thèse est focalisé sur des caractérisations microstructurales, des essais de fatigue et une modélisation multi-échelle du comportement en fatigue oligocyclique d’aciers 316L nanocristallisés superficiellement par SMAT. Le gradient de taille de grains superficiel, les contraintes résiduelles et l’écrouissage générés sont évalués à l’aide de différentes techniques : EBSD, DRX et essais de dureté. Le durcissement/adoucissement cyclique des éprouvettes SMATées et l'évolution de la microstructure au cours du chargement cyclique sont ensuite étudiés grâce à des essais de fatigue et des observations par EBSD. Une comparaison entre le SMAT et le grenaillage conventionnel est réalisée en analysant la topographie de surface, les champs de contraintes résiduelles et les profils d’écrouissage générés. Les effets de ces deux traitements sur la durée de vie en fatigue oligocyclique sont également étudiés.Une méthodologie de modélisation des contraintes résiduelles et de l’écrouissage est par ailleurs développée. Elle comporte une modélisation multi-échelle, la reconstruction des contraintes résiduelles et de l’écrouissage ainsi que la simulation du chargement cyclique. Une modélisation macroscopique de la plasticité cyclique de l’acier est d’abord réalisée. Une approche auto-cohérente du durcissement/adoucissement cyclique est ensuite développée. Enfin, une nouvelle méthode de reconstruction des contraintes résiduelles et de l’écrouissage est proposée et appliquée à une structure SMATée<br>This work focuses on experimental analysis and multiscale modelling of LCF behaviour of 316L steels treated by SMAT. The gradient microstructure features of a 316L steel treated by SMAT are characterized by EBSD, XRD and hardness tests. Grain size gradient, residual stress and plastic deformation are evaluated. The cyclic hardening/softening behaviour of the SMATed specimens and the evolution of the microstructures during cyclic loading are studied based on LCF tests and EBSD observations. A comparison between SMAT and conventional shot peening is performed by analysing the surface topography, residual stress fields, and work hardening profiles of the treated specimens as well as their effects on LCF life.A modelling methodology of residual stress and work hardening is developed including constitutive modelling, reconstruction technique, and cyclic loading simulation. First, a macroscopic constitutive modelling of the cyclic plasticity behaviour of a 316L steel is performed. Then, a self-consistent modelling of the cyclic hardening/softening behaviour is developed. Afterwards, a new method for reconstructing residual stress and work hardening is proposed and applied to a SMATed structure. Both of the previous macroscopic and microscopic models are used to predict the cyclic behaviour of the SMATed material

L’objectif de ces travaux de thèse se concentre sur deux points ciblés pour proposer des améliorations de la qualité de pièces en 316L issues de la technologie de FA par Selective Laser Melting (SLM).Le premier consiste à identifier les effets d’un traitement mécanique SMAT (Surface Mechanical Attrition Treatment) ainsi que des traitements thermiques sur les performances mécaniques de pièces issues de fabrication additive sous sollicitations monotone (traction) et cycliques (fatigue en flexion alternée).Le second porte sur la mise au point d’un post-traitement duplex qui combine le traitement SMAT avec un traitement thermique, réalisé soit par lampes à infrarouge, soit par passage d’un courant électrique, et d’évaluer les effets de ce nouveau type de post-traitement sur les propriétés mécaniques de l’acier 316L SLM.L'impact du traitement SMAT sur l’état de surface, la résistance mécanique en traction et la tenue en fatigue de cet alliage s'est avéré très bénéfique. L’amélioration des propriétés mécaniques a cependant été accompagné d’une baisse de ductilité. Le nouveau post-traitement duplex (SMAT/TT) a quant à lui permis d'augmenter davantage la tenue mécanique des pièces, tout en limitant leur baisse de ductilité<br>The objective of this PhD work is to focus on two points to propose improvements in the quality of 316L parts produced by Selective Laser Melting (SLM) AM technology.The first is to identify the effects of Surface Mechanical Attrition Treatment (SMAT) and heat treatments on the mechanical performance of additive manufacturing parts under monotonic (tensile) and cyclic (flexural bending fatigue) loading.The second is the development of a new duplex post-treatment that combines the SMAT with a heat treatment, using either infrared lamps or an electric current, and to evaluate the effects of this new post-treatment on the mechanical properties of a 316L SLM steel.The impact of SMAT on the surface quality, strength and fatigue life of this alloy was found to be very beneficial. However, this improvement in mechanical properties was accompanied by a decrease in ductility. The new duplex post-treatment (SMAT/TT) further increased the mechanical strength of the parts, while minimising the decrease in ductility induced by the SMAT alone

Full textAbstract:
Studying genetic diversity in natural and domestic populations is of major importance in evolutionary biology. The recent advent of next generation sequencing (NGS) technologies has dramatically changed the scope of these studies, enabling researchers to study genetic diversity in a whole-genome context. This thesis details examples of studies using NGS data to: (i) characterize evolutionary forces shaping the genome of the Atlantic herring, (ii) detect the genetic basis of speciation and domestication in the rabbit, and, (iii) identify mutations associated with skeletal atavism in Shetland ponies. The Atlantic herring (Clupea harengus) is the most abundant teleost species inhabiting the North Atlantic. Herring has seasonal reproduction and is adapted to a wide range of salinity (3-35‰) throughout the Baltic Sea and Atlantic Ocean. By using NGS data and whole-genome screening of 20 populations, we revealed the underlying genetic architecture for both adaptive features. Our results demonstrated that differentiated genomic regions have evolved by natural selection and genetic drift has played a subordinate role. The European rabbit (Oryctolagus cuniculus) is native to the Iberian Peninsula, where two rabbit subspecies with partial reproductive isolation have evolved. We performed whole genome sequencing to characterize regions of reduced introgression. Our results suggest key role of gene regulation in triggering genetic incompatibilities in the early stages of reproductive isolation. Moreover, we studied gene expression in testis and found misregulation of many genes in backcross progenies that often show impaired male fertility. We also scanned whole genome of wild and domestic populations and identified differentiated regions that were enriched for non-coding conserved elements. Our results indicated that selection has acted on standing genetic variation, particularly targeting genes expressed in the central nervous system. This finding is consistent with the tame behavior present in domestic rabbits, which allows them to survive and reproduce under the stressful non-natural rearing conditions provided by humans. In Shetland ponies, abnormally developed ulnae and fibulae characterize a skeletal deformity known as skeletal atavism. To explore the genetic basis of this disease, we scanned the genome using whole genome resequencing data. We identified two partially overlapping large deletions in the pseudoautosomal region (PAR) of the sex chromosomes that remove the entire coding sequence of the SHOX gene and part of CRLF2 gene. Based on this finding, we developed a diagnostic test that can be used as a tool to eradicate this inherited disease in horses.

Full textAbstract:
L’impact du grenaillage ultrasonique sur des alliages de titane et d’aluminium est étudié à température ambiante et à température cryogénique. Ce procédé peut aussi s'appeler attrition mécanique ultrasonique de surface (SMAT). La résistance en fatigue ainsi que le comportement tribologique sont étudiés afin de mieux comprendre les avantages et inconvénients liés à ce procédé. Deux alliages de titanes ont été choisis : un titane pur complètement α et un titane β-métastable sous sa forme complètement β. Ce choix permet de corréler l’influence de la microstructure initiale sur le traitement de déformation plastique sévère et sur les propriétés finales. Le titane β-métastable est sensible à la transformation martensitique induite par déformation ce qui permet d’explorer la possibilité d’introduire de la martensite à la surface grenaillée pour lutter, par exemple, contre la propagation de fissures courte lors des essais de fatigue. Le grenaillage à température cryogénique dans ce cas permet d’améliorer le déclenchement de la transformation martensitique. En plus d'aider la transformation martensitique, la température cryogénique permet d’augmenter la limite élastique des alliages lors du traitement, ce qui a pour impact de réduire le flux de matière à la surface grenaillée, améliorant ainsi l’intégrité de surface et entrainant un impact sur les propriétés tribologiques et en fatigue. Deux alliages d’aluminium à durcissement par précipitation ont également été étudiés : le 2024 et le 7075. Cette étude sur les aluminiums a pour but de comparer l’impact du grenaillage ultrasonique quand il est employé avant ou après le revenu de précipitation. Les dislocations produites lors du grenaillage ultrasonique servant de sites de nucléation préférentiels, l’objectif est d’explorer la possibilité d’améliorer (en termes de dureté par exemple) le revenu de précipitation en affinant la taille des précipités et en augmentant leur densité. L’emploi de deux séries d’aluminium devrait permettre de comparer l’effet du traitement sur les deux compositions différentes. De plus, ces deux alliages présentent des différences notables en termes de sensibilité aux défauts, ce qui permet d’étudier l’impact de l’intégrité de surface après grenaillage ultrasonique sur les propriétés mécaniques. L’étude des comportements tribologiques et en fatigue permet de tirer des conclusions quant à l’efficacité de ces traitements face à des conditions d’utilisation standards<br>The impact of ultrasonic shot peening on titanium and aluminium alloys is studied at room temperature and at cryogenic temperature. This process may also be called surface mechanical attrition treatment (SMAT). Fatigue strength and tribological behaviour are investigated in order to better understand the pros and cons of this process. Two titanium alloys were chosen: pure titanium in its fully α form and β-metastable titanium in its fully β form. This choice makes it possible to correlate the influence of the initial microstructure on the treatment of severe plastic deformation and on the final properties. The β-metastable titanium is sensitive to strain-induced martensitic transformation, which allows exploring the possibility of introducing martensite to the shot-peened surface to delay, for example, short crack propagation in fatigue testing. Shot peening at cryogenic temperature in this case improves the initiation of the martensitic transformation. In addition to facilitating martensitic transformation, cryogenic temperature shot peening increases the yield strength of alloys during processing, which has the effect of reducing the flow of material at the shot-peened surface. Thereby, it improves surface integrity and changes tribological and fatigue properties. Two precipitation hardenable aluminum alloys were also studied: 2024 and 7075. The purpose of this aluminium study is to compare the impact of ultrasonic shot blasting when used before or after precipitation aging. As the dislocations produced during ultrasonic shot-peening serve as preferential nucleation sites, the objective is to explore the possibility of improving (e.g. in terms of hardness) the precipitation aging by refining the size of the precipitates and increasing their density. The use of two series of aluminium should make it possible to compare the effect of the treatment on the two different alloying compositions. In addition, these two alloys show significant differences in terms of defect sensitivity, permitting to study the impact of surface integrity after ultrasonic shot-peening on mechanical properties. The study of tribological and fatigue behaviour allows to conclude about the effectiveness of these treatments under common conditions of use

Des travaux scientifiques récents ont ouvert de nouveaux champs d’application aux traitements mécaniques tels que le grenaillage. Il a été montré que de tels traitements, réalisés avant un traitement de nitruration à la surface d’alliage ferreux, permettaient d’abaisser les températures de traitement et d’augmenter significativement les cinétiques de diffusion. Nous avons entrepris de tester les performances de cette combinaison de traitements mécanique et thermochimique sur des aciers inoxydables et des alliages à base nickel austénitiques. Des essais ont été réalisés à partir d’une technique de grenaillage mécanique appelée « Surface Mechanical Attrition Treatment » (SMAT). Des billes en métal ou en céramique sont introduites dans l’enceinte et mises en mouvement par la sonotrode. Les billes percutent et introduisent donc une déformation plastique à la surface des échantillons. Après cette étape, les échantillons subissent un traitement thermochimique de nitruration assisté plasma. La comparaison des résultats obtenus après nitruration sur des échantillons traités mécaniquement avec ceux n’ayant pas été pré-traités mécaniquement a permis de quantifier les effets des traitements combinés. Les analyses par diffraction des rayons X, les mesures de microdureté, les observations au microscope optique/électronique à balayage/électronique en transmission, les analyses de texture par EBSD (Electron BackScatered Diffraction) et la mesure des profils de concentration en azote par SIMS (Secondary Ion Mass Spectrometry) et SDL (Spectroscopie à Décharge Luminescente) ont montré l’importance de la nature de la couche transformée mécaniquement sur la diffusion de l’azote<br>Recent scientific work has opened new fields of application to mechanical treatments such as shot blasting or peening. Indeed, it has been shown that this treatment, performed before a nitriding treatment on the surface of ferrous alloy, lowers processing temperatures and significantly increases the diffusion kinetics. We undertook to test this combination of mechanical and thermochemical treatments on stainless steels and nickel-based alloys. The mechanical treatments were done by Surface Mechanical Attrition Treatment (SMAT). This method is implemented in a box where metal or ceramic balls were introduced and set in motion by an ultrasound system in order to impact the surface of the pieces. The treated samples were then nitrided at low temperature by using a remote plasma. The comparison of the results obtained after nitriding treatments on mechanically treated samples and those not mechanically treated allows quantifying the effects of the combined treatments. Analyses by X-ray diffraction, microhardness measurement, observations by optical and scanning and transmission electron microscopy, texture analysis by EBSD (Electron Diffraction BackScatered) and measurement of nitrogen concentration profiles by SIMS (Secondary Ion Mass Spectrometry) show the importance of the nature of the deformed layer

Mat, språk och kultur är tätt sammanlänkade, och i matlagningsprogram förekommer en rad olika sorters kulturspecifika referenser. Kulturspecifika referenser definieras som ”any reference to a cultural entity which, due to its distance from the target culture, is characterized by a sufficient degree of opacity for the target reader to constitute a problem” (Mailhac i Ranzato 2015:54) och kan vara sådant t.ex. som måttenheter (pint), märken (Tabasco) och maträtter (surf and turf). Denna undersöknings fokus är översättningen av kulturspecifika referenser i matlagningsprogram, och eftersom merparten av de matlagningsprogram som översätts för svensk tv är på engelska består denna studies material av 21 engelskspråkiga matlagningsprogram och deras svenska översättningar. De matlagningsprogram som undersökts är Det goda livet, Jamie Olivers smarta rätter, David Roccos ljuva matresa – Italien, Kitchen Hero och Hela England bakar. Genom att att konstruera en korpus och analysera de kulturspecifika referenserna har normerna för översättningsstrategier gällande kulturspecifika referenser i matlagningsprogram kartlagts, och jämförts med resultaten från Pedersens välkända undersökning av primetime-TV (2011). Resultaten kategoriserades sedan enligt Pedersens taxonomi. Resultaten visade att normerna för matlagningsprogram liknade dem för primetime-TV, trots att det fanns ett par domänspecifika skillnader. Eftersom språk formar hur vi ser världen är det intressant att se hur kulturspecifika referenser översätts från en kultur till en annan, eftersom det formar hur den kulturen ses och värderas, eller åtminstone dess matkultur.<br>Food, language and culture are closely linked and cooking shows are peppered with culturally specific references. Culturally specific references are defined as “any reference to a cultural entity which, due to its distance from the target culture, is characterized by a sufficient degree of opacity for the target reader to constitute a problem” (Mailhac in Ranzato 2015:54) and can be things such as measurements (pints), brands (Tabasco), and dishes (surf and turf) to name a few. This study focuses on the translation of culture specific references in cooking shows. Since most of the cooking shows translated into Swedish are in English, the material for this study consists of 21 cooking shows in English and their Swedish translations. This study will look at the shows 3 good things, Save with Jamie, David Rocco’s Dolce Vita, Kitchen Hero and The Great British Bake off. By constructing a corpus and analyzing the culturally specific references, the norms regarding translation strategies for the translation of culturally specific references in cooking shows have been mapped out, and compared to the results of a well known study on primetime TV by Pedersen (2011). These were categorized in accordance with Pedersen’s taxonomy (2011:76). The results showed that the norms were very similar to those of primetime TV, with the exception of some domain-specific norms. Language influences how we see the world. Thus, the way culturally specific references are translated from one culture into another is important because it affects how cultures are viewed and interpreted, at least within the food community.

Indiana University-Purdue University Indianapolis (IUPUI)<br>Gait analysis plays a major role in treatment of osteoarthritis, knee or hip replacements, and musculoskeletal diseases. It is extensively used for injury rehabilitation and physical therapy for issues like Hemiplegia and Diplegia. It also provides us with the information to detect various improper gaits such as Parkinson's disease, Hemiplegic and diplegic gaits. Though there are many wearable and non-wearable methods to detect the improper gate performance, they are usually not user friendly and have restrictions. Most existing devices and systems can detect the gait but are very limited with regards of diagnosing them. The proposed method uses two A201 Force sensing resistors, accelerometer, and gyroscope to detect the gait and send diagnosed information of the possibility of the specified improper gaits via Bluetooth wireless communication system to the user's hand-held device or the desktop. The data received from the sensors was analyzed by the custom made micro-controller and is sent to the desktop or mobile device via Bluetooth module. The peak pressure values during a gait cycle were recorded and were used to indicate if the walk cycle of a person is normal or it has any abnormality.
Future work: A magnetometer can be added to get more accurate results. More improper gaits can be detected by using two PCBs, one under each foot. Data can be sent to cloud and saved for future comparisons.

Estes produtos, designados de legal highs, incluem uma grande variedade de compostos, como sais de banho, incensos, comprimidos, fertilizantes, spices entre outras formas, todas supostamente não indicadas para consumo humano. Apesar da falta de identificação de todos os constituintes destes produtos, diversos estudos identificaram moléculas com propriedades psicoativas, como os derivados de piperazinas, catinonas sintéticas, kratom, S. Divinorum e canabinóides sintéticos. Estes últimos constituem produtos muitas vezes utilizados como alternativas à canábis e, como tal, vistos como naturais e seguros pelos consumidores, o que não corresponde à verdade, sendo responsáveis por inúmeras hospitalizações. Assim, este trabalho focar-se-á nestes compostos, que são agonistas dos recetores canabinóides CB1 e CB2, tal como o Δ9-THC, principal composto psicoativo da canábis, embora, ao contrário deste, atuem na sua maioria como agonistas totais, apresentando por isso maior ocorrência de efeitos adversos com a mesma dose do que a canábis. Embora a extensão do seu metabolismo e farmacologia não sejam totalmente conhecidas, vários estudos reportam uma panóplia de efeitos adversos que inclui psicoses, alterações de humor, cognitivas, cardiovasculares, gastrointestinais, e também, potencial de abuso e síndrome de abstinência. Pelos inúmeros perigos associados a estas substâncias, os governos de muitos países, incluindo Portugal, adotaram medidas legais para impedir a sua proliferação. No entanto, este processo continua a ser um desafio pela rapidez como surgem novas moléculas que escapam ao controlo legal, mas, também, pela falta de métodos analíticos rápidos e validades de deteção destes compostos em amostras biológicas.

碩士<br>國立臺北科技大學<br>電子工程系研究所<br>105<br>Due to the mature development of smart phones, wearable devices become popularity.
Many companies focus on the development of brand-new wearable devices. According to Gartner forecast, the wearable device market increases 18.4% from 2015 to 2016 and up to 322 million units in 2017. In recent years, due to health consciousness, wearable devices has progressed in healthcare, medicine, and fitness. However, the current wearable devices only detect user physiological signal and can not collect surrounding environmental information. Furthermore, they can not discover the relationship among physiological, environmental and gait. In other words, the current wearable devices may not detect any possible danger, such as staggering or sprain. This paper proposes OCF standard based multi-sensor comprehensive smart shoes. In this paper, we use the pressure sensor for gait analysis, the ultrasonic/infrared sensors for surrounding detection, and the EMG sensor for internal physiological signal measurement. With the OCF standard, all data can be transmitted to the corresponding phone. Users can understand the surrounding environment using the phone to let their walk be safer.
The result shows the multi-sensor comprehensive smart shoes in this research can provide more than 80% correct rate for normal road, bumpy road and wet surface situation.

O setor industrial, sendo um dos grandes impulsionadores do desenvolvimento macroeconómico global, torna-se também um objeto interessante de investimento por parte de entidades públicas e privadas. Face à crescente procura por produtos e serviços que possam suprir as necessidades de toda a população mundial, torna-se necessário a criação em massa de produtos com o mínimo de gasto (zero waste) e o máximo de eficiência. Num chão de fábrica, este objetivo exige soluções que permitam a recolha e a troca de dados dos vários sistemas de informação que apoiam os seus processos de negócio. Estes dados permitem monitorizar as operações, melhorar o planeamento, melhorar os processos e reduzir os erros e defeitos de fabrico. O presente trabalho propõe uma arquitetura de software para a monitorização de um chão de fábrica, baseada no protocolo de comunicação máquina-máquina aberto Open Platform Communications - Unified Architecture (OPC-UA) desenvolvido pela OPC Foundation. Este protocolo posiciona-se para vir a ser um standard de facto da indústria. Os trabalhos iniciaram-se com um levantamento do estado da arte por forma a apurar como a digitalização das empresas fabris pode maximizar os indicadores de produtividade. Com base nos desafios identificados foi realizado um estudo de caso da digitalização de uma empresa de moldes com o desenvolvimento de uma framework que utiliza o protocolo industrial OPC-UA como forma de integração entre um sistema de informação do tipo Enterprise Resource Planning (ERP) e todos os serviços que compõem uma arquitetura de software industrial, permitindo observar em tempo real indicadores de desempenho, bem como digitalizar a gestão de ordens de fabrico num chão de fábrica. O presente projeto insere-se no projeto Mobilizador TOOLING4G – Advanced Tools for Smart Manufacturing (~ 7M€ e 32 parceiros) e enquadra-se no cluster engineering & tooling, que integra uma cadeia de valor alargada (do design ao produto final), para responder a clientes globais que cada vez mais pretendem soluções chave-na-mão.

Indiana University-Purdue University Indianapolis (IUPUI)<br>Reliability of the wide-area power system is becoming a greater concern as the power grid is growing. Delivering electric power from the most economical source through fewest and shortest transmission lines to customers frequently increases the stress on the system and prevents it from maintaining its stability. Events like loss of transmission equipment and phase to ground faults can force the system to cross its stability limits by causing the generators to lose their synchronism. Therefore, a helpful solution is detection of these dynamic events and prediction of instability.
Decision Trees (DTs) were used as a pattern recognition tool in this thesis. Based on training data, DT generated rules for detecting event, predicting loss of synchronism, and selecting stabilizing control. To evaluate the accuracy of these rules, they were applied to testing data sets.
To train DTs of this thesis, direct system measurements like generator rotor angles and bus voltage angles as well as calculated indices such as the rate of change of bus angles, the Integral Square Bus Angle (ISBA) and the gradient of ISBA were used.
The initial method of this thesis included a response based DT only for instability prediction. In this method, time and location of the events were unknown and the one shot control was applied when the instability was predicted. The control applied was in the form of fast power changes on four different buses. Further, an event detection DT was combined with the instability prediction such that the data samples of each case was checked with event detection DT rules. In cases that an event was detected, control was applied upon prediction of instability.
Later in the research, it was investigated that different control cases could behave differently in terms of the number of cases they stabilize. Therefore, a third DT was trained to select between two different control cases to improve the effectiveness of the methodology.
It was learned through internship at Midwest Independent Transmission Operators (MISO) that post-event steady-state analysis is necessary for better understanding the effect of the faults on the power system. Hence, this study was included in this research.
