Abstract:
Penuntut Umum dalam membuat dakwaan suatu dugaan tindakan pidana yang dilakukan oleh lebih dari satu terdakwa acap kali melakukan pemisahan perkara atau sering disebut dengan splitsing, kemudian dengan berkas perkara yang terpisah para terdakwa saling bersaksi untuk satu sama lain. Praktek demikian mengakibatkan proses persidangan menjadi berbelit-belit sehingga bertentangan dengan asas contante justitie. Memunculkan saksi dari perkara splitsing juga beresiko melanggar hak asasi Terdakwa karena mereka harus bersaksi atas tindak pidana yang dituduhkan kepada dirinya sendiri sehingga beresiko memberikan keterangan yang memberatkan dirinya sendiri, hal tersebut bertentangan dengan asas non self-incrimination. Pasal 142 KUHAP mengatur mengenai pemisahan perkara, dan mengatur dengan jelas bagaimana perkara dapat dilakukan pemisahan perkara. Namun dalam prakteknya pemisahan perkara tidak sesuai dengan maksud dan tujuan dari KUHAP yang diciptakan untuk memberikan penghargaan yang besar terhadap hak asasi manusia, justru sebaliknya digunakan untuk melanggar hak asasi manusia.

Abstract:
El presente trabajo de investigación es resultado de un rastreo contante de la variable inflación tanto en México como en Zacatecas por parte de cinco docentes-investigadores de dos unidades académicas de la Universidad Autónoma de Zacatecas, México durante el periodo 2012-2017. Los datos que se manejan fueron obtenidos de fuentes directas e indirectas que al contrastarlas con las oficiales (tanto federales como estatales), nos indican que la inflación ha tenido repercusiones directas en las compras de bienes y servicios que realizan de manera periódica la clase trabajadora de México y Zacatecas. En el sistema económico mexicano, la inflación en el período 2012-2017 se mantuvo bajo control por parte de las autoridades encargadas de ello. Es uno de los mayores logros obtenidos en materia económica del actual sexenio, una inflación por debajo del 10%. Ese indicador económico en México es resultado de una férrea contención del salario de la mayoría de los trabajadores, los cuales sufren el embate empresarial y gubernamental, lo mismo que de sus mismos sindicatos al no propiciar acciones tendientes a subir el bajo salario que tienen desde hace tiempo. Esta tendencia de bajas salariales en el sistema mexicano es resultado de negociaciones anuales sostenidas por la llamada comisión tripartita: trabajadores representados por sus sindicatos, empresarios que se agrupan en varias organizaciones y el sector gubernamental encabezado por la Secretaria de Trabajo y Previsión Social. Al mismo tiempo se escuchaban voces del mismo sector empresarial que proponían de inmediato un aumento a los salarios mínimos en México, argumentando que debe ser por arriba de los 150 pesos al día. También era noticia la posición de sectores económicos canadienses que establecen una posición de crítica contante hacia el bajo nivel salarial de la mayoría de los trabajadores en México.

Abstract:
In dit artikel wordt de wijze waarop woningcorporaties omgaan met jaarrekeningaspecten rond vennootschapsbelasting behandeld. De jaarrekeningen van de grootste 50 woningcorporaties zijn daartoe onderzocht. Op een aantal gebieden zijn goede jaarrekeningvoorbeelden (best practices) overgenomen uit de jaarrekeningen en van kort commentaar voorzien. Het belangrijkste aspect betreft de verwerking en waardering van tijdelijke verschillen in de jaarrekening. Het blijkt dat nagenoeg alle woningcorporaties contante waarde toepassen als waarderingsgrondslag voor de waardering van tijdelijke verschillen. Deze grondslag leidt vervolgens veelal tot een nihil-waardering voor vastgoed in exploitatie met een vervangingsdoel. Deze waardering hangt voor wat betreft belastbare tijdelijke verschillen samen met de fiscale doorschuiffaciliteit waarmee de fiscale afrekening in beginsel onbeperkt kan worden uitgesteld. Voor verrekenbare tijdelijke verschillen hangt de nihil-waardering samen met de onzekerheid met betrekking tot fiscale winstrealisatie. Uit het artikel blijkt dat het overgrote deel van de woningcorporaties latente belastingvorderingen heeft opgenomen die vanuit verschillende bronnen zijn ontstaan. Specifiek hebben we de toelichting op de waardering van voorwaartse verliescompensatierechten onderzocht. In het artikel wordt ook ingegaan op de hoogte van en de toelichting op het effectieve belastingtarief inclusief aansluitingen met het toepasselijke belastingtarief. De mediaan van het effectieve belastingtarief ligt op het lage percentage van 4. De fiscale doorschuiffaciliteit doet zich gelden in dit lage percentage. Tot slot is onderzocht hoe de samenhang tussen de te vormen herwaarderingsreserve en de opgenomen tijdelijke belastingverschillen is toegelicht. Op dit onderdeel is de kwaliteit van de toelichting bij het merendeel van de onderzochte woningcorporaties ondermaats. Het artikel sluit af met een nabeschouwing waarin de belangrijkste bevinding van dit onderzoek - de in de populatie gangbare praktijk van waardering tegen contante waarde leidend tot nihil-waardering van de belastbare verschillen – op zijn merites wordt beoordeeld.

Abstract:
La tesi si propone di mettere in luce i punti di contatto e di reciproca interazione fra la disciplina dell’antiriciclaggio e le indagini fiscali, evidenziandone i punti di forza e le criticità. Viene evidenziato come delle misure pensate per prevenire comportamenti criminali e per la tutela del sistema finanziario nel suo complesso possano influenzare significativamente - seppur indirettamente - le dinamiche dell’accertamento tributario. La grande mole di informazioni raggiunta e gestita nell’ambito delle procedure antiriciclaggio, infatti, può essere incrociata con gli altri dati di natura fiscale già a disposizione dell’amministrazione finanziaria offrendo un riscontro sulla veridicità della documentazione contabile e commerciale di un’impresa o sul tenore di vita palesato da una persona fisica. A questo si aggiunge il grande supporto offerto dalle disposizioni in tema di limitazione dell’uso del contante che, convogliando la maggior parte delle transazioni finanziarie in canali tracciati, contribuiscono a rendere visibile ciò che avrebbe potuto rimanere “sommerso”, esercitando anche un forte impatto psicologico in termini di deterrenza, attraverso la diffusione di una generale sensazione di controllabilità. Ciò nonostante, è certamente un errore attribuire all’antiriciclaggio una diretta valenza fiscale. Le tasse si pagano su ciò che si vede, e tracciare i trasferimenti contribuisce a rendere visibili i passaggi di “moneta”, ma nulla dice in merito alla ragione economica per cui questi siano avvenuti. Proprio per superare questo limite si è cercato di imporre ad una vasta categoria di soggetti (finanziari e professionali) uno specifico obbligo di collaborazione attiva, un onere di approfondimento “economico sostanziale” dell’operazione finanziaria e di segnalazione di quelle “sospette”. Ma sull’attendibilità di tali approfondimenti e sulla completezza delle informazioni a cui i collaboratori dello Stato possono accedere il dibattito è aperto, in fondo non si tratta né di organi di polizia, né di soggetti con particolari potestà “investigative”, si tratta solo di soggetti che devono intervistare dei loro clienti e registrarne le risposte. Spesso, peraltro, sarà proprio l’“intervistatore” a consigliare (in veste di consulente di fiducia) le risposte da fornire. Ma l’antiriciclaggio non è solo segnalazione, è soprattutto patrimonio informativo e cultura della trasparenza e della responsabilità (che si vorrebbe diffondere in tutti gli operatori economici e finanziari).
The dissertation aims to highlight the points of contact and mutual interaction between the discipline of anti-money laundering and tax investigations, especially underlining the strengths and weaknesses. It will be shown that measures designed to prevent criminal behavior and meant to protect the financial system as a whole can influence significantly - though indirectly - the dynamics of the assessment of taxation. In fact, the large amount of information collected and managed within the ambit of anti-money laundering rules and regulations can be cross-checked with further fiscal data already available for revenues authorities, in order to achieve a financial and commercial feedback on the accuracy of records in relation to an enterprise or with reference to the standards of living of an individual. Not to mention the great support given by the provisions concerning restrictions on the use of cash money that - conveying most of the financial transactions through predetermined channels - help to reveal what could have stayed "hidden"; furthermore, they exert a great influence in terms of psychological deterrence thanks to the dissemination of a general feeling of controllability. Nevertheless, it is certainly a mistake to attribute to anti-money laundering a direct fiscal value. Taxes are paid on what is apparent and, if on one hand tracing the transfers helps to make visible the money transfers themselves, on the other it says nothing about the economic reason why they occur. In order to get around this limit, it was made compulsory for a wide group of people both, financially and professionally speaking, to be actively cooperative; that is to say that they now have to develop a “substantial economic role” with reference to the financial operation and, at the same time, they are also asked to report of those that are considered "suspicious". It has to be said that the debate is open in relation to the reliability of such investigations and information completeness, to which State employees can have access. In the end, we are coping with neither police force nor subjects equipped with special powers of "investigation". It is only a matter of individuals which have to interview their clients and record their answers. And it will be just the 'interviewer' who -as a trustworthy advisor- will recommend what answer is to be given. But anti-money laundering is not just reporting, it is -first and foremost- informative heritage and culture of transparency and accountability (which would be desirable to spread among all economic and financial operators).

Abstract:
On introduit trois types de structures géométriques nouvelles sur des variétés différentiables : formes de contact généralisé, couples de contact et couples contacto-symplectiques. Une forme de contact généralisé sur M est une 2k + 1-forme ω telle que ω∧dω soit une forme volume. Plusieurs exemples sont construits et on donne un critère local qui permet de montrer que tous ces exemples ne sont pas triviaux dans le sens qu'ils ne sont pas de la forme α ∧ dαk (où α est une forme de contact). Un couple de contact sur M est un couple (α, β) de formes de Pfaff de classe constante 2k + 1 et 2h + 1 respectivement et telles que la forme α ∧ dαk ∧ β ∧ dβh soit une forme volume. Chacune de ces formes détermine un feuilletage caractéristique dont les feuilles sont des variétés de contact. Ces feuilletages sont transverses et supplémentaires. La géométrie de tels objets est très riche car on peut naturellement leur associer deux champs de Reeb qui commutent, deux types de courbes de Legendre et deux crochets de Poisson. D'une manière similaire on définit un couple contacto-symplectique. Pour les deux dernières structure on démontre qu'il y a un unique modèle local et on construit plusieurs exemples non triviaux dans les groupes de Lie et dans les fibrés principaux en tores. Comme conséquence de la théorie des couples contacto-symplectiques on construit des exemples de champs de vecteurs (sur des variétés de contact) sans transversale fermée et qui ne sont le champ de Reeb d'aucune forme de contact. Ce qui répond à un célèbre problème de Reeb.

Abstract:
The tangential contact stiffness for ground Ti-6Al-4V surfaces is measured to linearly decrease with the application of tangential load. At the beginning of the application of tangential load, for ground surfaces, the ratio of the tangential contact stiffness to the normal contact stiffness is seen to be approximately half the Mindlin ratio. This is consistent with many other published experimental studies. Measurements of normal contact stiffness for ground surfaces conform to a model that posits a linear relationship between normal contact stiffness and normal load. An equivalent surface roughness parameter is defined for two surfaces in contact; and the normal contact stiffness for ground surfaces is observed to be inversely proportional to this parameter. Single asperity models were constructed to simulate the effect of different frictional laws and plasticity on the tangential displacement of an asperity contact. Further, multi-asperity modelling showed the effect of different normal load distributions on the tangential behaviour of interfaces. In addition, normal contact stiffness was modelled for a grid of asperities taking into account asperity interactions. A receding contact problem for which the required form of the distributed dislocations is bounded-bounded was solved. Then, a fundamental 2D frictional receding contact problem involving a homogeneous linear elastic infinite layer pressed by a line load onto a half-plane of the same material was analysed. This was done by the insertion of preformed distributed dislocations (or eigenstrains), which take into account the correct form of the separation of the interface at points away from the area of loading, along with corrective bounded-bounded distributions. The general method of solution was further refined and adapted to solve three other receding contact problems. The solutions demonstrated the robustness and applicability of this new procedure.

Abstract:
This thesis examines the influence of asperities such as found on the teeth of gears and discs, and failure mechanisms associated with rough surface Elastohydrodynamic Lubrication (EHL). The principal outcomes of the research provide a good insight into fatigue life, residual stress effects, damage prediction and surface contact failures. In particular, the study is intended to provide understanding into the residual stress distribution resulting from plastic deformation of surface asperities in the running in process. The residual stress is then added to the asperity elastic stress distribution and examined in detail to see the effects on fatigue damage and fatigue life. So, a theoretical model has been developed to assist design against the residual stress effect and surface contact fatigue, such as micropitting. The technique used in the study starts with developing an elastic plastic model of the rough surface by using the Abaqus Finite Element analysis software package. This is a nonlinear problem and ranges of applied loads have been applied to the as-manufactured surfaces causing the asperity features to experience varying degrees of plastic deformation. The pre and post running roughness profiles are studied in order to assess the level of plastic deformation actually occurring at significant surface asperity features by aligning the pre and post running profiles. This results in a new technique that has helped to identify the level of plastic deformation occurring in the practice, and also to make a comparison with FEA contact analysis for the same asperity features to identify the appropriate residual stress field. The residual stress field associated with the plastic deformation was extracted and evaluated. The extracted residual stress field was transferred to a form that facilitated IV inclusion in stress evaluation code to obtain the stress history for the material subject to loading in an EHL contact. The research carried out considers surface fatigue analysis with and without a residual stress field, so as to establish the influence of asperity plastic deformation on the fatigue properties of the surface. All the work is based on numerical simulation of surface fatigue failure in EHL situations and carried out numerically. The procedure can be applied quickly and gives the opportunity to apply several models and investigate the influence of all the model parameters on material deformation and fatigue life.

No presente trabalho foi desenvolvida uma teoria de característica elétrica da estrutura metal-isolante-metal considerando uma camada fina de óxido entre o metal e o isolante, sendo o óxido um outro isolante de banda de energia proibida mais larga. Foi considerada uma distribuição energética uniforme de estados de impurezas à interface óxido-isolante. Estudamos a distribuição real do potencial na região de carga espacial usando a equação de Poisson. Através desta distribuição obtemos a relação entre o potencial de contato e a carga positiva na região de depleção e assim a característica capacitância-voltagem da estrutura. Este tipo de característica é útil para se calcular as características corrente em função do potencial e corrente em função do tempo para um dado potencial e deste modo é importante para o entendimento das estruturas MIM e MOIM.
In this work we have developed a theory of electric characteristic of the metal-oxide-insulator-metal structure, considering a thin film of oxide between metal and insulator; the oxide is another insulator of wider forbidden energy gap. A uniform energy distribution of impurity states at the oxide-insulator interface was considered. W e have studied the actual distribution of potential in the region of spatial charge using the Poisson equation. With this distribution we obtain the relation between the contact potential and the charge in the depletion region and then the characteristic potential - capacitance of t his structure. This type of characteristic is useful to calculate the characteristic current - potential, and current-time at a given potential . In this manner it is important to the understanding of MIM and MOIM structures.

Abstract:
A novel method for coupling fluid pressure and crack deformation for the purpose of analysing rolling contact fatigue (RCF) cracks in lubricated, hydrodynamic and elastohydrodynamic, contacts is presented. The model addresses some of the simplifying assumptions applied to existing models presented in the literature such as: (i) using an imposed fluid pressure gradient inside the crack, (ii) using an imposed fluid pressure at the crack mouth, and (iii) adopting a surface contact pressure, Hertzian or EHL, that does not account for the fluid flow in and out of the crack during loading. The model has been used to model the effect of lubricant/crack interaction in various RCF configurations as the rolling element passes over the pre-formed crack; which has direct application to bearings and rail/wheel contacts. The results of the simulations performed with the fully-coupled fluid/solid solver developed by the author suggest that the cracked component/lubricant interaction contributes significantly to accelerate the rate of surface breaking crack growth in rolling element bearings and wheel/rail type contacts. It is shown through simulations that the lubricant works as a catalyst inside the crack to convert the compressive contact load into a crack opening, tensile fatigue mechanism, through the effect of fluid pressurisation inside the crack. The results obtained using such a model suggest that the opening associated with the fluid action within the crack induces large mode I stress intensity factors. This has been shown to be the principal factor that promotes and influences the rate of rolling contact fatigue crack growth in lubricated contacts. In addition to the modelling work, an experimental method of analysing RCF cracks in real time has been developed. The technique is based on laser induced fluorescence that allows the penetration of the fluid within the crack to be observed. Though the method would require development to be used to provide results that could be used for quantitative comparisons with crack models, some encouraging preliminary results have been obtained: the technique has been shown to be suitable for measuring, at least qualitatively, the real time evolution of the film thickness in RCF cracks.

Abstract:
Sistemas dinâmicos ferroviários são modelados levando-se em consideração as forças de contato roda trilho. As equações de movimento são fortemente influenciadas pela determinação dessas forças, o que requer o conhecimento da mecânica de contato, ferramenta imprescindível na previsão do comportamento de uma composição ferroviária. O rodeiro é responsável por receber as excitações na forma de irregularidades e imperfeições da via e transferi-la para a suspensão primária. A proposta dessa dissertação consiste em realizar simulações no domínio do tempo, da resposta do comportamento dinâmico do rodeiro ferroviário de 2 graus de liberdade. O modelo matemático equivalente é desenvolvido. A rigidez de contato e a conicidade são linearizados em torno de um ponto de operação, próximo ao centro da via. É apresentada a influência da velocidade na estabilidade para o modelo linearizado e para a conicidade variando de 0.1 a 1.0. Os respectivos modos de vibrar também são apresentados. Em seguida, o modelo matemático não linear do rodeiro ferroviário é gerado por software especializado na criação de sistemas de multicorpos, VAMPIRE, que permite a criação das equações de movimento através da topologia do sistema. O modelo é criado seguindo a proposta do benchmarck apresentada pela International Association of Vehicle System Dynamics (IAVSD). O rodeiro recebe uma força lateral crescente que se estabiliza em 20kN. O rodeiro é excitado com a aplicação de outra força lateral a uma taxa de 50kN/s até o descarrilamento. As forças longitudinais, laterais que aparecem no contato, o ângulo do plano de contato, ângulo de yaw e afastamento lateral são comparados com o benchmarck e outros autores.
Railway dynamics systems are modeled regarding the creep forces between wheel-rail. The equations of movement are strongly influenced by these forces, what requests the knowledge of the theory in mechanical of contact, necessary tool to foresee the behavior of a railway vehicle. The wheelset is responsible by receiving the perturbations of irregularities and transfer them to the primary suspension. A railway vehicle is composed by primary and secondary suspensions. The proposal is based on performing simulations in the time domain, dynamic mresponse of a railway wheelset of two degrees of freedom. The mathematical model is developed. The stiffness of contact and conicity are linearized around an operation point, near to track center. The influence of speed is determined to linearized model and to a range of 0.1 to 1.0 in the conicity. The eigenvectors are presented. In the following, the non linear model of the wheelset is generated using a specialized package of multi body system, VAMPIRE. The package creates equations of movement after the generation of the topology. The non linear mathematical model are defined by the benchmark proposed by International Association of Vehicle System Dynamics (IAVSD). The wheelset is submitted to 20kN at the rail level.

Abstract:
El tema de la presente tesis es La vinculación turca respecto al léxico español y la función de las lenguas transmisoras, cuyo contenido está estructurado en siete apartados: introducción, estado de la cuestión, metodología, análisis, conclusión, bibliografía y apéndice. La investigación trata de las palabras tomadas del turco que existen en la lengua española, las que también denominamos “turquismos”. Hoy en día no se distingue mucho la diferencia entre turquismo y arabismo. Uno de los propósitos de esta tesis es demostrar que este tipo de préstamos son de procedencia distinta. El objetivo principal, sin embargo, es el de intentar justificar, a partir de los datos que hemos recogido y analizado, que la lengua turca también debe considerarse en la historia del léxico del español. Hasta estos momentos, se ha demostrado ampliamente la influencia de los musulmanes de origen árabe en la península ibérica, pero los árabes no fueron los únicos islamitas que se relacionaron con la Península; los turcos también lo hicieron desde diferentes puntos de vista durante largo tiempo, aunque de forma más indirecta. Es evidente que cualquier contacto entre naciones conlleva el intercambio de palabras, y, por esta razón, en el léxico español han aparecido préstamos directos e indirectos de procedencia turca, aunque no sean demasiados si los comparamos con el número de arabismos. Existen también lenguas transmisoras a través de las cuales han llegado al español determinados turquismos. Son el francés, el italiano, el ruso, el árabe, el inglés, entre otras. En la presente investigación se analizan todos los procesos de transmisión de estas voces, se demuestran las áreas semánticas de las que forman parte y su frecuencia de uso en el lenguaje español. Algunos de los ejemplos del corpus son: fez, sultán, horda, turbante, café, hurra, yogur, chamerluco, tabor, corbacho, zapato, tulipán, caftán, atamán, bajá, etc. Algunos de ellos tienen incluso derivados creados en el propio español, que también se han incluido en el corpus de esta investigación. El número total de los préstamos del turco, directos e indirectos, que se ha extraído de fuentes lexicográficas para la elaboración de la presente tesis doctoral, es 130. Entre las distintas palabras, se observa que los sustantivos (82% de todo el corpus) son más frecuentes que los adjetivos u otras partículas. Esto no es de extrañar, ya que los sustantivos son más numerosos que el resto de palabras por tener el rasgo de nombrar todo tipo de objetos entre otros conceptos. La importancia de este trabajo está determinada por el hecho de que sus resultados puedan ser utilizados en estudios posteriores para resolver problemas en este ámbito del origen de las palabras. Es un trabajo importante porque el estudio de la influencia del turco es innovadora y está poco estudiada. Esta tesis puede tener un papel importante en el contexto del léxico español para que su temática pueda desarrollarse de un modo más profundo que hasta el momento.
The theme of the thesis is Direct and indirect Turkish loanwords on the vocabulary of the Spanish language and the function of intermediary languages. It consists of seven sections: introduction, objective, methodology, analysis, conclusion, bibliography and appendix. The research deals with a linguistic analysis of foreign words borrowed from Turkish that are widely used in the Spanish language, which we also call “turquismos”. Today the difference between “turquismo” and “arabismo” has not been thoroughly investigated. One of the objectives of the thesis is to demonstrate the evidence of this type of loanwords originated from different sources. Based on the selected and analyzed materials, we have made an attempt to prove that the Turkish language has left its traces in the Spanish lexicon during the historical periods of the language and its society. Until now, the influence of Arabian muslims in the Iberian Peninsula has been amply demonstrated, but the Arabs were not the only Islamists who were related to the Peninsula; the Turks also did it from different points of view for a long time, although in a more indirect way. It is evident that any contact between the nations involves the exchange of words, and for that reason, direct and indirect loans of Turkish origin have appeared in the Spanish lexicon, although not too many, if we compare them with the number of Arabisms. There are also intermediary languages through which certain Turkish loanwords were integrated in the Spanish vocabulary. They are French, Italian, Russian, Arabic, English and some others. All the transmission processes of these words, their semantic fields and the frequency of their usage in the Spanish language are analyzed. Some examples of the corpus are: fez, sultán, horda, turbante, café, hurra, yogur, chamerluco, tabor, corbacho, zapato, tulipán, caftán, atamán, bajá, etc. Some of them even have derivatives formed in Spanish itself, which have also been included in the corpus of this research. The total number of direct and indirect Turkish loanwords, which has been selected from lexicographical sources for the doctoral thesis, is 130. It has been observed that the nouns (82% of the whole corpus) are more frequent than adjectives or other parts of the speech. It is not surprising that nouns are more numerous than the rest of the words as they have the feature of naming all kinds of things and objects among other concepts. The theoretical importance of this research is determined by the fact that its results can be used in later studies to solve linguistic problems in the field of etymology of vocabulary units. Its practical significance lies in the study of the influence of the Turkish languages which is innovative. The thesis can have an important role in the context of the Spanish lexicon so that its subject can be developed extensively in the future.

Abstract:
Rolling contacts are utilized in many technical applications, both in bearings and in the contact between gear teeth. These components are often highly loaded, which makes them susceptible to suffer from rolling contact fatigue. This work focuses on the rolling contact fatigue mechanism of pitting. In order to attain a better understanding of why pitting initiates and grows, detailed simulations of rolling contacts have been performed. In particular the contact between two gears in a truck retarder was here used as a case study. The investigated contact experienced elastohydrodynamic lubrication conditions since the load was high enough to causes the surfaces in contact to deform and the viscosity of the lubricant to increase significantly. In Paper A it was investigated if surface irregularities in the size of the surface roughness are large enough to cause surface initiated fatigue. The investigation focused on the pitch line since small surface initiated pits were found here even though there was no slip present. Since there were pits present at the pitch line, it is important that the theories of pitting can explain the development of pits also in the absence of slip. The conclusion of the work was that surface irregularities of the size of normal surface roughness are enough to cause surface initiated fatigue at the pitch line. In Paper B it was investigated why pits are more likely to initiate in the dedendum of pinion gears than in the addendum. In both areas slip is present but in different directions. In the dedendum the friction from slip is against the rolling direction which enhances the risk for pitting. The investigation was performed by studying the effect of the temperature rise in the contact caused by the slip. The conclusion drawn was that the temperature rise in the contact explained why pitting was more common in the dedendum than in the addendum.
Rullande kontakter förekommer i många applikationer, till exempel i lager och mellan kugghjulständer. Både lager och kugghjul utsätts ofta för höga laster vilket gör att dess ytor löper stor risk att utmattas, vilket kallas rullande kontaktutmattning. Denna studie fokuserar på pitting, även kallat spalling, vilket är en typ av rullande kontaktutmattning där en utmattninsspricka växer fram som får delar av ytan att ramla av. För att få en bättre förståelse varför pittingskador uppkommer har noggranna simuleringar utförts av rullande kontakter. Kontakten mellan två tänder på kugghjul i en lastbilsretarder har används som underlag då många pittingskador påträffats på dem.  För att minska friktionen och nötningen i kontakten mellan kuggtänderna användes smörjmedel. De höga lasterna lastbilsretardern utsattes för deformerade kuggarnas ytor elastiskt samtidigt de kraftigt ökade viskositeten hos smörjmedlet. Dessa förhållanden gör att kontakten kallas för elastohydrodynamiskt smord, vilket på engelska förkortas till EHL. I Artikel A undersöktes om små ytojämnheter kan orsaka ytinitierade pittingskador. Eftersom skadan påträffats i friktionslösa kontakter, så som vid rullcirkeln på de undersökta kugghjulen, är det viktigt att teorierna som förklarar uppkomsten inte är beroende av friktion. Undersökningen fokuserade därför på förhållandena vid rullcirkeln.  Slutsatsen från arbetet var att små ytojämnheter, av samma storleksordning som ytojämnheterna på de undersökta kugghjulen, är tillräckligt stora för att orsaka utmattningsskador. I Artikel B undersöktes varför det är vanligare att pitts initieras i dedendum än addendum på drivande kugghjul. Kontakten på båda sidorna om rullcirkeln slirar svagt åt olika håll. Att kontakten slirar skapar friktion som är motriktad rullriktningen i dedendum vilket ökar risken för pittingskador. För att undersöka varför dessa förhållanden ökar risken för skador fördjupades analysen av kontakten genom att inkludera temperaturfältet. Simuleringarna visade att temperaturen ökar genom kontakten vilket orsakar en asymmetrisk spänningsfördelning. Denna asymmetriska spänningsfördelning gör att ytojämnheter i dedendum är troligare att orsaka skador än ytojämnheter i addendum.

Abstract:
AbstractIn recent years, research has increasingly focused on the complex processes involved in friction contacts. Especially in tribological high-loaded contacts, characterized by the presence of contact modifying wear particles, macroscopic friction shows a surprisingly high dynamic complexity on many temporal and local scales. There are dominant effects on mesoscopic scales such as the geometric self-organization structures of the wear dust in the contact, which can significantly change the local contact surfaces. For the description and simulation of these phenomena, abstract methods have shown their effectiveness. One class of methods are cellular automata, both volume- and particle-based. The latter are in particular the Movable Cellular Automata developed by Sergey Psakhie. The scales of these discrete methods are freely selectable in wide ranges between the macro world and the atomic scale. Nevertheless, they provide reliable information on mesoscopic balances in the boundary layer and thus also on the macroscopic behavior of the tribocontact. The success of these methods is shown by the example of an automotive brake. The question of the relative insensitivity of the scales of these mesoscopic methods is examined in detail.

Abstract:
AbstractManual contact tracing has been a key component in controlling the outbreak of the COVID-19 pandemic. The identification and isolation of close contacts of confirmed cases have successfully interrupted transmission chains and reduced the disease spread. Even though manual contact tracing has been widely used, its practice has shown that it is slow and cannot be scaled up once the epidemic grows beyond the early phase. In this case, digital contact tracing can play a significant role in controlling the pandemic. In this chapter, based on our experience and lessons learned from the Smittestopp project, we discuss the main prerequisites for the efficient implementation and validation of digital contact tracing in a population. Specifically, we discuss how to translate a close contact defined for manual tracing to proximity events discovered by a phone, that is, how to define a meaningful risk score and validate the digital contact tracing. We discuss challenges related to each step and provide solutions to some of them, even though questions still remain.

Abstract:
A frequência elétrica, em Sistemas Elétricos de Potência (SEPs), é uma característica de elevada importância pois influência diretamente no funcionamento dos equipamentos presentes na rede e na qualidade de energia fornecida. Esse artigo apresenta a implementação de algoritmos de estimação de frequência em Digital Signal Processor (DSP) F28377s com intuito de utilização em simulações de sistemas elétricos de potência em simuladores de tempo real. Os algoritmos apresentados são baseados em detecção por passagem por zero, Transformada Rápida Fourier (FFT) e Transformada Discreta Fourier (DFT). Os métodos foram submetidos a casos de sinal com frequência contante, com frequência variada com degrau, rampa, adição de harmônicas e presença de ruído gaussiano. Os resultados apresentados pelos métodos foram comparados pela análise dos índices de tempo de convergência e erro de estimação em regime permanente. Os resultados dos métodos aqui apresentados foram satisfatórios e evidenciaram vantagem dos algoritmos baseados em Transformada de Fourier.

Abstract:
O ensino de engenharia é uma tarefa extramente complexa e deve estar em contante evolução, uma vez que o público-alvo (alunos) também estão em constante evolução. As metodologias modernas do processo ensino-aprendizagem apontam para a necessidade de o aluno ser protagonista deste processo. As metodologias, chamadas ativas, tais como aprendizagem baseada em problema e sala de aula invertida estão baseadas fortemente na aplicação prática dos conteúdos teóricos vistos em sala de aula. Para que a aplicação dessas metodologias seja possível é necessário, então, uma estrutura mínima, composta de equipamentos e bancadas didáticas. Assim, este trabalho visa contribuir com os cursos de engenharia da Universidade Federal de Santa Maria Campus Cachoeira do Sul, com o desenvolvimento de um veículo elétrico com abastecimento por energia solar com a finalidade de servir como bancada de estudos práticos de conceitos correlato as áreas de ciência e tecnologia. Foi desenvolvido um carro com capacidade para um passageiro utilizando um motor de aproximadamente 1 HP e autonomia superior à 30 minutos. Ainda são propostos planos de aula e ações práticas para a utilização nas disciplinas do curso de Engenharia Elétrica. A elaboração desta banca contribuiu fortemente na formação de habilidades profissionais, técnicas e pessoais dos alunos envolvidos.

Abstract:
The mechanics of snow friction are central to competitive skiing, safe winter driving and efficient polar sleds. For nearly 80 years, prevailing theory has postulated that self-lubrication accounts for low kinetic friction on snow: dry-contact sliding warms snow grains to the melting point, and further sliding produces meltwater layers that lubricate the interface. We sought to verify that self-lubrication occurs at the grain scale and to quantify the evolution of real contact area to aid modeling. We used high-resolution (15 μm) infrared thermography to observe the warming of stationary snow under a rotating polyethylene slider. Surprisingly, we did not observe melting at contacting snow grains despite low friction values. In some cases, slider shear failed inter-granular bonds and produced widespread snow movement with no persistent contacts to melt (μ < 0.03). When the snow grains did not move and persistent contacts evolved, the slider abraded rather than melted the grains at low resistance (μ < 0.05). Optical microscopy revealed that the abraded particles deposited in air pockets between grains and thereby carried heat away from the interface, a process not included in current models. Overall, our results challenge whether self-lubrication is indeed the dominant mechanism underlying low snow kinetic friction.
