ABSTRACT The topic of the diploma thesis bears the title Possibilities of using technical means of narcotics checks in road traffic. The thesis endeavours to describe, compare and evaluate searching methods that are used in road checks for habit-forming drugs by public officials. The theoretical part is focused on the description of individual groups of habit-forming drugs and their effects on the human organism. Further, the theoretical part contains an overview of the most frequently used analytic methods. The practical part deals with the questions of detection aids used by the traffic police in the Czech Republic. Based on the methodology used, which included research in domestic and foreign sources and a structured interview, all the information obtained was thoroughly evaluated and it illustrates the substance of the topic. This diploma thesis is structured in such a way that enables its use by police units and other organisations that take part in fighting the use of habit-forming drugs. The thesis can be also a contribution for tuition as study material.

Among the physical and chemical properties, Cetane Number (CN) is one of the most common indicators of the diesel quality. Beyond the standard method (ASTM D613) for CN determination, there are others alternative methods, such as ASTM D6890, ASTM D4737, through infrared spectroscopy and the portable IROX DIESEL. This work aimed to evaluate and compare alternative methods for CN determination and applying non-parametric statistical tests (Friedman, Wilcoxon). There were selected randomly 80 samples that were in accordance with ANP specifications and subsequently assayed in triplicate. According to statistical analysis, the CN determinations through ASTM D6890 and infrared spectroscopy have no significant differences at a significance level of 5%. CN results through ASTM D4737 and IROX DIESEL were statistically different from each other and when they are compared with the previous mentioned methods at a significance level of 5%. The infrared spectroscopic technique shows to be an alternative for obtaining CN if it is included in diesel oil specifications because it is a technique that requires less cost of implementation and maintenance, fast and accurate determination requiring no external calibration and easy operability. / No Brasil, a maior empregabilidade do óleo diesel é no sistema rodoviário de transporte de cargas, tornando necessário um rigoroso acompanhamento da qualidade de ignição deste combustível Dentre os parâmetros físicos e químicos, o Número de Cetano (NC) é um dos mais comuns indicadores da qualidade do óleo diesel. Além do método padrão (ASTM D-613) para determinação do NC, existem outros métodos alternativos, como, ASTM D-6890, ASTM D-4737, por técnicas de espectroscopia no infravermelho e pelo aparelho portátil IROX DIESEL. O presente estudo teve como objetivo avaliar e comparar métodos alternativos para determinação do NC, utilizando-se teste de estatísticas não paramétricas (Friedman, Wilcoxon). Foram selecionadas aleatoriamente 80 amostras que estivessem em conformidade com as especificações da ANP e posteriormente ensaiadas em triplicatas. De acordo com análise estatística, os resultados das determinações de NC pelo método ASTM D-6890 e por técnicas de espectroscopia no infravermelho, não possuem diferenças significativas ao nível de significância de 5%. Já os resultados de NC dos métodos ASTM D-4737 e IROX DIESEL, foram estatisticamente diferentes entre si e também quando comparados com os métodos anteriores mencionados ao nível de significância de 5%. A técnica de espectroscopia no infravermelho mostra ser uma alternativa para obtenção do NC se incluído nas especificações de óleo diesel, pois é uma técnica que requer menor custo de implementação e manutenção, determinação rápida e precisa não requerendo calibração externa e de fácil operação.

It is the act of executing a software product in order to validate whether it behaves as intended and identify possible malfunctions. Studies have shown that testing makes up more than 50% of the development cost. Besides, much effort and emphasis have now been placed on tasks related to automation with the purpose of reducing cost and the participation of the human element in software activities. Testing is a human-based activity. Therefore, efficient ways of testing software products for quality assurance will require a better and more comprehensive understanding of testers’ feelings, perceptions, and motivations, referred to as Tester Experience (TX). Thus, the better the TX of developers during testing, or anyone who takes up the role of a tester, the better the result. TX can be defined as a means of capturing how testers think and feel about their activities within the software testing environment, with the assumption that an improvement of the tester’s experience has a positive impact on quality assurance. This thesis motivates the importance of TX, proposes concepts, issues, definition and factors affecting TX. It also proposes an approach, namely, the Tester ExperienceBased Approach (TX-A), composed of guidelines and activities that developers (or testers) can follow in order to improve their TX in addition to the factors affecting TX. Moreover, this work presents the results of a survey carried out with software development practitioners in order to evaluate TX-A which evaluates the importance of the factors and the relevance of the guidelines in improving TX. The results obtained show that more than 95% of participants agree that the factors are important and the guidelines relevant for improving TX. / Teste é uma atividade essencial para o desenvolvimento de software. É o ato de executar um produto de software para validar se o mesmo se comporta como previsto e identificar possíveis falhas. Estudos demonstraram que os testes compõem mais de 50% do custo de desenvolvimento. Além disso, muito esforço e ênfase têm sido dedicados em tarefas relacionadas à automação com o objetivo de reduzir custos e a participação do elemento humano em atividades de teste de software. No entanto, teste é também uma atividade humana. Assim, formas eficientes de testar produtos de software para garantia de qualidade exigem uma compreensão melhor e mais abrangente dos sentimentos, percepções e motivações dos testadores, conhecido como Tester Experience (TX). Dessa forma, quanto melhor o TX dos desenvolvedores durante o teste, ou qualquer um que assumir o papel de testador, melhor será o resultado. O TX pode ser definido como um meio de capturar como os testadores pensam e sentem sobre suas atividades dentro do ambiente de teste de software, com o pressuposto de que a melhoria da experiência do testador tenha um impacto positivo na garantia de qualidade. Esta dissertação demonstra a importância do TX, propõe conceitos, definições e fatores que afetam o TX. Ela também propõe uma abordagem, denominada, Tester Experience-Based Approach (TX-A), composta por diretrizes e atividades que os desenvolvedores (ou testadores) devem seguir para melhorar seu TX, além dos fatores que afetam o TX. Além disso, este trabalho apresenta os resultados de um survey realizado com profissionais de desenvolvimento de software para avaliar a TX-A. O estudo avaliou a importância dos fatores e a relevância das diretrizes na melhoria do TX. Os resultados obtidos mostram que mais de 95% dos participantes concordam que os fatores são importantes e as diretrizes são relevantes para melhorar o TX.

Det finns idag behov av att ta fram information om hur vatten flödar i marken. För att undersöka detta brukar det installeras grundvattenrör. Grundvattenrör används oftast i syfte att bevaka grundvattennivåer i marken men kan även användas för att utföra hydrauliska tester vars syfte är att skatta jordens hydrauliska egenskaper. Det är då framförallt den hydrauliska konduktiviteten som söks. Kunskap om markens hydrauliska konduktivitet är bland annat viktig för modellering av grundvattenflöden och beräkning av föroreningsspridning. Genom åren har det utvecklats ett antal hydrauliska tester för att ta fram hydrauliska egenskaper i jorden. Från de ursprungliga testerna med pumprör och observationsrör (interferenstester) har det tillkommit metoder för att genomföra tester i enskilda grundvattenrör. Idag kan bland annat pumptest och slugtest genomföras för att skatta hydrauliska egenskaper i enskilda grundvattenrör. Examensarbetet har undersökt olika hydrauliska tester som genomförs i enskilt grundvattenrör. Testerna har varit pumptest, injektionstest, slugtest med solid slug, slugtest med vatten och stigningsmätning. Testerna har genomförts i 11 olika grundvattenrör. Grundvattenrören har varit placerade i olika jordarter och akvifertyper. Alla tester har gjorts i alla rör för att kunna göra en jämförelse mellan testerna. Resultat från testerna visar att det föreligger en variation i skattade hydrauliska egenskaper när en jämförelse gjordes mellan alla slugtester och alla pumptester. Pumptesterna gav generellt en mindre variation mellan test och modellösning och visar sig därför mer oberoende av testtyp och val av modellösning. Slugtesterna visade skillnad i skattad hydraulisk konduktivitet beroende på modellösning. Modellösningarna Hyder mfl. (1994)/KGS och Dougherty-Babu (1984) för slugtest gav en högre skattning hydraulisk konduktivitet än pumptesterna medan modellösningen Bouwer-Rice (1976) gav en lägre skattning av hydraulisk konduktivitet än pumptesterna. Testerna skiljer sig åt när de genomförs i olika jordarter. I lågkonduktiva jordarter är det svårt att genomföra olika typer av pumptest då dessa är påverkade av brunnsmagasin och det krävs att pumpflödet är tillräckligt lågt för att grundvattenröret inte ska torrläggas eller svämma över. Därför är det rekommenderat att utföra slugtest i lågkonduktiva jordarter. I högkonduktiva jordarter är det rekommenderat att göra pumptester då slugtester genererar färre mätpunkter och kan därför leda till fel i modelleringen. / There is a need today to gain information on how water moves in the ground. Groundwater pipes are therefore installed to monitor the groundwater levels. These groundwater pipes can however be used to perform hydraulic tests to obtain information regarding hydraulic properties of the soil. Hydraulic tests are usually performed to investigate the water flow in the soil. This water flow is called hydraulic conductivity. Information on hydraulic conductivity is, for example, essential in modeling of pollutant transport. Several types of hydraulic tests have been developed throughout history in the purpose to investigate hydraulic properties in the soil. The original tests involved pumping tests where one pipe was pumped while an adjacent pipe was used to monitor water level changes. From these original pumping tests there has been a development where the methods can be applied in a single groundwater pipe. Typical single-well tests used today are pumping tests and slug tests. This thesis has investigated and evaluated different hydraulic test performed in single groundwater pipes. Two types of pumping test have been performed: pumping test with constant flow, where the water is pumped out from the pipe, and injection test where water is pumped into the pipe with a constant flow. Three types of slug test have been performed: slug test using a solid slug, slug test using water and rising head test. Slug test is a test where the water level in the pipe is rapidly lowered or raised. The time it takes for the water to return to the initial water level is measured and used to calculate the hydraulic conductivity of the soil. The tests have been performed in 11 different groundwater monitoring pipes. The groundwater pipes were situated in different types of soil and aquifers. All the tests were performed in all the pipes to be able to compare them. Different model solutions were used to analyze the measured data from the hydraulic tests. The results showed variation in estimated hydraulic conductivity when the average hydraulic conductivity of pumping tests and slug tests were compared. The different types of pumping tests had on average a small difference in hydraulic conductivity and the results were on average independent of model solution used. Depending on the model solution there was a difference in hydraulic conductivity for the slug tests. The model solutions of Hyder et al (1994)/KGS and Dougherty-Babu (1984) for slug test estimated over-all a higher hydraulic conductivity than the pumping tests while the model solution of Bouwer-Rice (1976) estimated over-all a lower hydraulic conductivity than the pumping tests. The results and performance of the tests behaved differently depending on the type of soil. It was difficult to perform pumping and injection tests in low conductivity soils due to well-bore storage in the groundwater pipe. It is therefore recommended to perform slug tests in low conductivity soils and pumping tests in high conductivity soil because slug tests generates fewer measurements than pumping tests and can cause errors in the modeling.

Viva la Diva är ett Svenskt makeup-varumärke som nyligen har lanserat sin nya webbplats. Denna webbplats har inte blivit testad på deras slutanvändare eller målgrupp. Genom att använda en heuristisk utvärdering och 12 Think aloud-tester har flera användbarhetsproblem upptäckts där designen behöver förbättringar. Senare i rapporten presenteras några förbättringsförslag om hur användarupplevelsen kan förbättras på webbplatsen, men också hur problemen som jag fann under utvärderingen och Think aloud-testerna kan lösas. Jag tillhandahåller också för Viva la Diva ett designförslag för en av deras sidor som inte är helt färdig i designen. Detta arbete ger insikt i hur man kan använda en heuristisk utvärdering och Think aloudtester för att upptäcka användbarhetsproblem på webbplatser. / Viva la Diva is a Swedish makeup-brand that has recently launched their new website. This website has not been tested with their end-users or target users. By using a heuristic evaluation and 12 Think aloud-tests several user problems have been discovered where the design needs improvements. Later in the article I present some suggestions on how to improve the user experience on the website, as well as fix the problems that I found during the evaluation and Think aloud-tests. I also provide Viva la Diva with a design suggestion for one of their pages that is not completely finished in the design. This work provides insights on how to use a heuristic evaluation and Think aloud-tests to discover usability problems on websites.

Les chercheurs au travers de plusieurs domaines essaient de fournir des solutions pour intégrer les objets et les systèmes dans l’internet des objets (IdO ou IoT pour Internet of Things en anglais). Il y a deux domaines parmi les domaines les plus importants d’IdO. Le premier est de tester et évaluer l’IdO. Plusieurs milliards d’objets sont déjà connectés à l’internet. Ces objets peuvent communiquer entre eux directement sans intervention humaine. Les entreprises et les développeurs doivent être capable de tester et d’évaluer des scénarios différents dans plusieurs environnements. Ces environnements doivent être capable d’échanger des services entre eux. Nous présentons notre architecture IoTaaS (Internet of Things Testing As A Service). IoTaaS est un environnement distribué pour tester et évaluer l’IdO. Nous présentons aussi la première mise en oeuvre expérimentale qui est appelée CEMAT (Cloud Environment for Mobile Application Testing) qui permet de tester les applications mobiles et les objets connectés. Le deuxième domaine correspond aux méthodes de communication. Nous présentons notre conception de communications COLDE (Connectionless Data Exchange) pour échanger une petite quantité de données publiques entre les clients Wi-Fi et les points d’accès sans qu’ils aient besoin d’être associés. Alors que COLDE présente la méthode nécessaire pour échanger ces données, le concept de services Lightweight décrit les données échangées en utilisant le protocole COLDE. / Researchers across many domains are working to provide solutions that enable integration of objectsand systems into the Internet of Things (IoT). There are two domains which are among the mostimportant ones in IoT. First domain is IoT testing and evaluation. The billions of objects whichare connected to IoT would intercommunicate without any human intervention. Enterprises anddevelopers should be able to test and evaluate different operational scenarios of their systems indifferent environments. Testing environments should be able to exchange services. We present ourarchitecture IoTaaS (Internet of Things Testing As A Service). IoTaaS is a hierarchy of a distributedcloud for testing and evaluating IoT. We also present the pilot implementation of IoTaaS under thecode name CEMAT (Cloud Environment for Mobile Application Testing) which focuses on mobiledevices and their connected objects. The second domain is about communication methods andtechniques. Several IoT applications depend on public data exchange. We present our design toexchange small amount of public data on wireless network without establishing a connection. COLDE(Connectionless Data Exchange) is our extension to protocol the IEEE 802.11. COLDE utilizesthe management frames to allow Wi-Fi devices and access points to exchange small amounts ofdata without having any association. COLDE describes how we can exchange data without beingconnected. Lightweight services concept explains which data could be transferred using COLDE.Simulation experiments and real world implementation are presented along with their results.

När stadsbyggnadsprojekt planeras och städer omformas, var kommer medborgares kunskap om sin omgivning in? Hur behåller eller skapar medborgarna en anknytning till stadens platser, när deras användning och identitet förändras? Om staden ska vara en allmän rättighet krävs det att den växer fram kollektivt. Därför måste medborgares kunskap tas till vara på i stadens utveckling och i konkreta stadsbyggnadsprojekt. Det är svårt att se hur medborgare kommer få en koppling till dessa platser när de under en lång tid av stadsomvandlingen är avskärmade från den. Hur kan dessa platser, istället för att exkludera medborgare, bli en del av deras vardag redan under planerings- och förändringsprocesser? Hur kan medborgarnas delaktighet i planerings- och byggprocessen vara med om att bygga upp värden för platsers framtida användare?I Jubileumsparken i Göteborg används en metod planerarna kallar platsbyggnad. Arbetet bygger på att koppla samman medborgare med platsen under planeringen av den nya stadsdelen i Frihamnen genom att skapa urbana prototyper. Prototyperna öppnar upp för medborgarna att använda och utveckla platsen medan den planeras och tar fysisk form.Genom att prototyperna är i ett konstant flöde av användning och omvandling kan nya förståelser av hur planering kan gå till och vad platsen kan bli skapas. Prototyperna hjälper till att gå från något flytande (planer, idéer, visioner) till något fast.I studien ställer vi oss frågorna: var kommer idén om prototypprojekt ifrån? Hur har idén vuxit fram? Hur har prototyperna utvecklats och förändrats? Hur förstår och använder olika aktörer prototyperna och hur fungerar de i arbetet med Jubileumsparken?Prototyperna i sig själva hamnar i ett gränsland mellan aktörers relationer till prototyperna. Kontrasten av aktörernas relation till prototyperna gör det svårt att definiera vad prototyperna egentligen är, men genom att för en stund gör relationerna till något fast kan vi studera dem. När prototyperna är stabila och relationerna inte längre kommer omvandlas, och inga nya relationer kommer skapas, så har de kanske slutligen övergått till något fast. Men kommer de någonsin bli permanenta? Kanske är de bara i ett fast tillstånd för en stund? De är fasta objekt så länge inga relationer skapas eller omvandlas. / When urban construction projects are planned and cities are transformed, where will citizens’ knowledge of their surroundings come in? How do the citizens create or keep an attachment to the city’s places when their use and identity change? If the city is to be a universal right, it is required that it grows collectively. Therefore, citizens’ knowledge must be taken into account in the city’s development and in concrete urban construction projects. It’s hard to see how citizens will get a connection to these sites when they are shielded from the urban transformation for a long time. How can these places, instead of excluding citizens, become part of their everyday lives during the planning and construction process? How can citizens’ involvement in the planning and construction process help to build up the values ​for site’s future users?Jubileumsparken in Gothenburg uses a method the planners call space building. The work is based on linking citizens with the site during the planning of the new district in Frihamnen by creating urban prototypes. Prototypes open up for citizens to use and develop the site while it’s being planned and taking physical form. Because the prototypes are in a constant flow of use and conversion, new understandings of how planning can be and how the site can be created. Prototypes help move from something floating (plans, ideas, visions) to something solid.In the study we are asking the following questions: where does the idea of ​​prototype projects come from? How has the idea emerged? How have prototypes evolved and changed? How do different actors understand and use prototypes and how do they work in Jubileumsparken?The prototypes themselves end up in a borderland between actors’ relations with the prototypes. The contrast of the actors’ relation to the prototypes makes it difficult to define what the prototypes really are, but by making the relationships solid for some time we can study them. When the prototypes are stable and the relationships will no longer be transformed, and no new relationships will be created, they may eventually have shifted to something fixed. But will they ever become permanent? Maybe they are just in a solid state for a while? They are fixed objects as long as no relationships are created or converted.

This semestral paper deals with the issues of testing and requirements examinations for cables and cable harnesses. These terms are defined in the work and the difference in their meaning is described. The work also describes the characteristic features of cables and cable harnesses, explains their importance and focuses in more detail on the variable properties that may change over time or that are dependent on manufacturing errors. The principles and procedures of tests of these properties are covered in the work and are the essence of the subsequent practical part. In this part, the work deals with the design of the measuring circuit prototype for testing of the insulation resistance of cables and their desired continuity in bundles. This design is then physically implemented, the processes of designing and implementing are described in detail and finally its functionality is tested and presented to the reader.

The aim of this dissertation is to focus on the systems design of a multi purpose engine tester, a device for diagnostic techniques of self propelled motor vehicles to be used in a car mechanics work shop. The principle aim is to combine a permanently installed PC, a portable laptop and a workshop trolley containing all the necessary assembly tools and accessories. These three pieces used together will serve as a self contained unit within the workshop. I will compare the quality of the devices with others on the market. I will talk about the layout of the individual parts such as the design, structure and shape of the unit, as well as the ergonomics of the designed pieces. An important factor will be reducing the size of the device without compromising the quality and keeping it a similar price to other similar products on the market.
