As soluções encontradas atendem outras aplicações que requerem sincronismo remoto de tempo. O trabalho foi desenvolvido em diferentes áreas que englobam contadores de alta precisão; relógios com resolução de nano segundo; enlaces de rádio para disseminação de tempo e determinação de distância; geradores de seqüências codificadas para detecção e identificação de campos de contagem; supressores digitais de jitter com uso de média de amostras; e sincronizadores de marcha para osciladores baseados em quartzo. Os contadores de alta precisão foram pesquisados para construção do relógio de alta resolução. Como resultado foi obtida uma solução inédita empregando linhas de retardo com contadores independentes. Esta configuração possibilita aliar alta resolução de contagem com uso de osciladores de referência operando em baixa freqüência sem que a incerteza do processo seja aumentada em função dos erros de não linearidade de interpolação. Os enlaces de rádio foram construídos com interface síncrona entre as bases de transmissão e recepção empregando modulação FSK (Frequency Shift Keying) e os erros nas medidas de tempo de propagação nos circuitos causados pela influência de jitter foram minimizados através do cálculo de média das amostras tomadas em cada campo de contagem. No intuito de viabilizar a implementação de um sistema de baixo custo, foi desenvolvida uma técnica inovadora de sincronização de marcha entre elementos osciladores de quartzo do tipo OCXO (Oven Controlled Crystal Oscillator). Esta técnica de sincronização permite que o sistema opere com estabilidades equivalentes a referências baseadas em rubídio. Os sistemas eletrônicos digitais foram construídos com solução FPGA (Field Programmable Gate Array). / Abstract: This thesis present new proposals for time dissemination systems, which were analyzed and implemented as complete solutions providing high resolution in radio links focusing in the requirements of the new geolocation system known as GEOLOCAL. The solutions found are useful for other applications equiring time synchronization. The work has been developed in different areas that include high precision counters; nanosecond resolutions clocks; radio links for time dissemination and measurements of distance; coded sequence generators for detection and identification of counting fields, digital jitter suppressors using samples averaging and clock synchronizers for quartz based oscillators. High precision counters have been investigated for the purpose to construct a high resolution clock. As a result it has been obtained a unique solution using delay lines with independent counters. This configuration allows the obtaining high count resolution with the use of low frequency reference oscillators, without increasing the system uncertainties due to interpolation non-linearity errors. The radio links were constructed with synchronous interface between the transmission and reception bases using FSK (Frequency Shift Keying) modulation. The measurements errors due to jitter in circuit propagation were minimized by calculating the average of samples taken every count set. In order to implement a low cost system, it has been developed an innovative clock synchronization technique between quartz oscillator elements to the type OCXO (Oven Controlled Crystal Oscillator). This synchronization technique produced stabilities equivalent to those obtained with rubidium-referred oscillators. The digital systems have been constructed using FPGA (Field Programmable Gate Array). / Doutorado / Telecomunicações e Telemática / Doutor em Engenharia Elétrica

Die steigende Nachfrage nach mechanischen Kleinuhren und deren monopolhafte, meist in Schweizer Unternehmen erfolgte Fertigung der Uhrenkomponenten, führten zu einem stetig zunehmenden Interesse, historisch gewachsene handwerkliche Vorgaben und Vorschriften zu hinterfragen. Genauere Fertigungstechnologien, die Verwendung neuerer Materialien und die Möglichkeit des Einsatzes heutiger Rechentechnik bei der Auslegung und Qualitätssicherung, welche beispielsweise in der Feinwerktechnik, dem Maschinenbau oder der Fahrzeugtechnik seit Jahren Stand der Technik sind, führen zu Forschungsaufgaben mit der Möglichkeit, ermittelte theoretische Ergebnisse mit reichlich handwerklichen Erfahrungen der Uhrmacher zu stützen. Das Interesse, die Funktionsweise der einzelnen Teilsysteme im Uhrwerk genau zu analysieren, Möglichkeiten der Anpassung sowohl fertigungsbedingt als auch wirkungsgrad- und genauigkeitssteigernd aufzuzeigen und zu definieren führte zur Anfertigung dieser Arbeit. Mit dieser Arbeit wird ein Beitrag geschaffen, welcher das systematische Vorgehen bei der Analyse und der Berechnung der Uhrwerkskomponenten Räderwerk und Schweizer Ankerhemmung beschreibt. Es werden theoretische Untersuchungen aufgeführt, Optimierungsparameter herausgestellt und Messungen an realen Uhrwerken durchgeführt, insbesondere zur Validierung der theoretischen Untersuchungen. Mit der Auswertung der Messergebnisse werden Möglichkeiten gezeigt, geometrische und kinematische Problemstellungen zu identifizieren und gezielt anzupassen.

My research topic concerns how learners use the analogue clock (as a human tool) to make meaning of clock time. This study is informed by a Vygotskian socio-cultural framework to learning and development based on the concept that human activities take place in cultural contexts and is mediated by tools. In this qualitative study I report on the learners meaning making of analogue clock time using the physical clock. This study was carried out at a South African primary school through an intervention programme after school. The research employed a case study method. It involved a purposeful sample of 4 learners (n=38) from the grade four class group based on their response to a baseline assessment task. The selected sample of learners included learners across the ability spectrum to gain rich insight into how learners make meaning of analogue clock time. Data collection and analysis was done through an interpretive approach. The video-taped interviews and intervention programme was my main instrument of data collection. Other research instruments included document analysis of responses to baseline assessment tasks. These research tools yielded the data collected and also allowed for triangulation. My research topic explored how the learners make meaning of analogue clock time. In particular the two-way movement of how the learners use the physical tool namely the analogue clock to develop meaning and how the clock mediates clock knowledge in return. The findings of the study suggest that learners’ find it difficult to conceptualise analogue clock symbols and signs, in particular, in Afrikaans the half hour concept, in relation to the two hands. The physical analogue clock is also important to support and extend clock knowledge in solving time-related problems. This shows the power of the analogue clock to mediate meaning making of clock time in young learners. Because of its potential to improve teaching and learning analogue clock time in primary school it is therefore recommended that the analogue clock time be further researched in South Africa.

There are more and more parents that are considering to purchase smart watches for their kids. The children’s smart watches on the market are usually equipped with many practical functions like the GPS positioning, the camera and the messaging. Among all the smart watches for children, the ones that can be connected via a mobile application called SeTracker are popular for the acceptable prices. These smart watches may have different brands although they come from the same manufacturer company and share the common service and database. The security of the mobile application is essential to the security of the products. But are they designed in a secure way? There were reports about vulnerabilities of the products previously. Unfortunately, the security requirements do not stop upon solving those vulnerabilities. In this project, it was found that the parents can track the kids and communicate with them through the mobile application, but their accounts might be logged on the attacker’s phone at the same time. And it is surprisingly easy to get the password of the users because it is stored in a local file using simple substitution cipher. There are other examples of insecure design in the products. Among them are the unlimited attempts to send and enter verification codes used for changing the password. It seems that the server does not have a complete logging and monitoring mechanism to prevent abnormal behaviors. The security analysis and penetration testing of this project would provide an example of the mobile hacking, and it will also raise a warning on the security of smart devices. / Det finns fler och fler föräldrar som funderar på att köpa smarta klockor till sina barn. De smarta barnklockorna på marknaden är vanligtvis utrustade med många praktiska funktioner som GPS, kamera och meddelanden. Bland alla smarta klockor för barn är de som kan kopplas upp via en mobilapplikation som heter SeTracker populära för de acceptabla priserna. Dessa smarta klockor kan ha olika märken även om de kommer från samma tillverkarföretag och delar den gemensamma tjänsten och databasen. Säkerheten för den mobila applikationen är väsentlig för produkternas säkerhet. Men är de designade på ett säkert sätt? Det fanns rapporter om sårbarheter i produkterna tidigare. Tyvärr slutar inte säkerhetskraven när man löser dessa sårbarheter. I det här projektet fann man att föräldrarna kan spåra barnen och kommunicera med dem via mobilapplikationen, men deras konton kan vara inloggade på angriparens telefon samtidigt. Och det är förvånansvärt lätt att få användarnas lösenord eftersom det lagras i en lokal fil med hjälp av enkla ersättnings-chiffer. Det finns andra exempel på osäker design i produkterna. Bland dem är de obegränsade försöken att skicka och ange verifieringskoder som används för att ändra lösenordet. Det verkar som om servern inte har en fullständig loggnings- och övervakningsmekanism för att förhindra onormalt beteende. Säkerhetsanalysen och penetrationstesten av detta projekt skulle ge ett exempel på mobilhackning, och det kommer också att väcka en varning om säkerheten för smarta enheter.

Bakgrund: Tiden är en av de äldsta mänskliga konstruktionerna och ett fenomen som människor alltid velat mäta. Detta har människan gjort genom alla tider med hjälp av allt från solur, astronomiska ur till mekaniska ur. I dagens moderna samhälle där människor har en ständig tillgång till displayer som visar hur mycket klockan är, fortsätter den Schweiziska klockindustrin att exportera för miljontals Schweiziska franc och efterfrågan tycks inte påverkas av de elektroniska prylarna och ”smartphones”. När tiden inte är det relevanta längre eller det som konsumenter strävar efter vid köp av en klocka, ställer vi oss frågan om vad det är som driver folk till att vara villiga att lägga ner så mycket pengar på en sådan produkt? Vad är det för värde som huvudsakligen uppfattas och varierar de mellan konsumenterna beroende på klockans syfte? Genom att undersöka faktorer inom de olika värdekategorierna Socialt-, Hedonistiskt- och Funktionellt värde, och med hjälp av två olika konsumenttyper, har författarna som avsikt att slutligen klargöra vilka faktorer som är mer eller mindre värdeskapande. Studien bidrar till en kartläggning och en kunskapsspridning om vilka faktorer som är mest värdeskapande, inte bara gällande klockor, men även för hela premiumindustrin. Syfte: Syftet med denna studie är att identifiera vilka faktorer som är av vikt och har betydelse för konsumenters uppfattning om värde när det gäller premiumprodukter. För att utreda detta har vi valt att fokusera på klockindustrin där vi avser undersöka och fastställa vilka faktorer som till högre eller lägre grad har betydelse för konsumentens uppfattning om vad som genererar ett värde. Genomförande: Studien har ett interpretativistiskt synsätt och är en deduktiv studie som karaktäriseras av ett kvalitativt tillvägagångssätt. Empirin har samlats in genom ett bekvämlighetsurval med inslag av målstyrt urval. Sammanlagt har 9 intervjuer med privatpersoner genomförts. Slutsats: Studien visar på att de värdeskapande faktorerna varierar beroende på konsumenttyp samt deras syfte med köpet. Orsakerna till hur konsumenter uppfattar faktorer som värdeskapande beror på vad konsumenten strävar efter, hur insatt konsumenten är i ämnet samt dess bakgrund. De värdeskapande faktorerna går även att väva samman och utgör ofta ett ökat värde tillsammans. / Background: Time is one of the oldest constructions created by humans and a phenomenon that humans always wanted to measure. This has been done by humans throughout all ages, using everything from sundials, astronomical watches to mechanical watches. In today's modern society, where people have constant access to displays showing the time, the Swiss watch industry continues to export for millions of Swiss francs and the demand does not seem to be affected. When time is neither the factor nor the reason why people are buying a watch, what is causing people to spend money on such a product? What types of values are essentially perceived and do they vary between consumers depending on their purpose of the watch? By examining factors within the different categories of value; the Social-, the Hedonistic- and Functional value, and by using two different types of consumers’, the authors have the intention to clarify which factors are of more or less value- creating. The study contributes to a mapping and dissemination of knowledge about which factors are the most value creating ones, not only regarding watches, but for the entire premium industry. Purpose: The purpose of this study is to identify which factors are important and of significance to consumers' perception of value in terms of premium products. As a case for investigating this issue, the authors have chosen the watch industry where they intend to investigate and determine which factors are of higher or lower importance to the consumer's perception of what has generated value-creation. Completion: The study has an interpretative approach and is a deductible study characterized by a qualitative approach. The empirical data has been collected through a convenience sample with elements of a target sample. A total of 9 interviews with private individuals have been conducted. Conclusion: The study shows that the value-creating factors vary depending on the consumer type and their purpose of the purchase. The reasons for how consumers perceive factors as value creating depend on what the consumer strives for, how committed the consumer is to the subject and the consumer’s background. The value-creating factors can also be put together and often constitute an increased value.
