This thesis investigates the possibilities of finding solutions, in order to reduce the total time spent for testing and waiting times for running multiple automated test cases in a test framework. The “Automated Test Framework”, developed by Axis Communications AB, is used to write the functional tests to test both hardware and software of a resource. The functional tests that tests the software is considered in this thesis work. In the current infrastructure, tests are executed sequentially and resources are allocated using First In First Out scheduling algorithm. From the user’s point of view, it is inefficient to wait for many hours to run their tests that take few minutes to execute. The thesis consists of two main parts: (1) identify a plugin that suits the framework and executes the tests in parallel, which reduces the overall execution time of tests and (2) analyze various scheduling algorithms in order to address the resource allocation problem, which arose due to limited resource availability, while the tests were run in parallel. By distributing multiple tests across several resources and executing them in parallel, help in improving the test strategy, thereby reducing the overall execution times of test suites. The case studies were created to emulate the problematic scenarios in the company and sample tests were written that reflect the real tests in the framework. Due to the complexity of the current architecture and the limited resources available for running the test in parallel, a simulator was developed with the identified plugin in a multi-core computer, with each core simulating a resource. Multiple tests were run using the simulator in order to explore, check and assess if the overall execution time of the tests can be reduced. While achieving parallelism in running the automated tests, resource allocation became a problem, since limited resources are available to run parallel tests. In order to address this problem, scheduling algorithms were considered. A prototype was developed to mimic the behaviour of a scheduling plugin and the scheduling algorithms were implemented in the prototype. The set of values were given as input to the prototype and tested with scenarios described under case studies. The results from the prototype are used to analyze the impact caused by various scheduling algorithms on reducing the waiting times of the tests. The combined usage of simulator along with scheduler prototype helped in understanding how to minimize the total time spent for testing and improving the resource allocation process.

Automated tests have become the most sought after method of testing in today’s market. Automating systems is generally found to be cheaper, faster and more reliable than manually operating them. For this reason many companies decide to make the switch over to this inexpensive yet efficient way of testing, only to realize that their costs have in fact gone up. The reasons for this could be poor planning, automating too much too soon or even automating unnecessary parts of the system. This study takes a closer look at the effects of automating tests used on interlocking systems. A tool has been developed as a part of the automated tests at Bombardier. The main function of the tool is to speed up the testing process by automatically generating test cases rather than having a worker write them down. The aim of this paper is to present this recently developed tool and show how its use significantly reduces testing time, costs and workload compared to the manual tests used today.

Running automated tests can be a time-consuming task, especially when doing regression testing. If the sequence of the execution of the test cases is arbitrary, there is a good chance that many of the defects are not detected until the end of the test run. If the developer could get the failing tests first, he would almost immediately be able to get back to coding or correcting mistakes. In order to achieve this, we designed and analyzed a set of test case prioritization techniques. The prioritization techniques were compared in an experiment, and evaluated against two existing techniques for prioritizing test cases.Our implementation of the prioritization techniques resulted in a tool called Pritest, built according to good design principles for performance, adaptability and maintainability. This tool was compared to an existing similar tool through a discussion.The problem we address is relevant for the increased popularity of agile software methods, where rapid regression testing is of high importance. The experiment indicates that some prioritization techniques perform better than others, and that techniques based on code analysis is outperformed by techniques analyzing code changes, in the context of our experiment.

Automated software testing is often very helpful when performing functionality testing. It makes it possible to have a lot of user actions performed within the application without the need for a human interaction. But would it be possible to extend the behavior of regular functionality testing scripts and use them for performance testing? This way we could have regular application usage testing performed automatically during longer runs as well as investigate how well the application performs over time.This report presents the process of making test automation scripts run in a manner that makes it possible to analyze the tested application’s performance and limitations over time – not just its functionality. Additionally, a research is performed on how to choose proper test automation suites, appropriate tools and in which way to make it possible to efficiently gather performance related data during the test automation runs.This work has been done at the company Tobii Technology and it is used to test a desktop application they develop, called Tobii Studio. As a result of our work, we have implemented a test suite that can run automated tests over a long period of time while monitoring runtime performance for both the application and the computer’s hardware. The resulting tests can be used repeatedly by Tobii to help them identify performance issues for common test cases, and newer versions of Tobii Studio can be tested in the future to verify that a certain level of performance is maintained. The designs of our tests are so general that it will be possible for Tobii to continue extending our suite with more functionality.

GUI testing is expensive to perform manually. Software systems involving a heterogeneous set of components exclude the applicability of specific GUI testing techniques. Visual GUI Testing (VGT) is a test automation technique that combines image recognition with scripts. It applies to almost any GUI driven application. VGT is proven to be cost-effective in comparison with manual testing. Still, it is expensive to maintain. This study investigates if test script design by following specific guidelines positively affects maintenance costs. A case study was conducted to identify best practices for VGT w.r.t. maintenance time. Four VGT versions were developed for each manual test case. These consisted of two design versions, with/without guidelines, for the two VGT-tools EyeAutomate and Sikuli. Data was collected using time measurements, observations, and interviews. Results highlighted differences in initial development time and maintenance time between the two design versions. In total, 44 observations were collected. 17 were related to the design versions, 17 to the VGT-tools, and 10 to VGT in general, initial development, and the system under test. The interviews collected the perceptions of VGT in general, maintenance of the different VGT versions, and guidelines. In conclusion, the combination of the guidelines did not have a positive effect on maintenance in terms of costs and experience. However, some of the individual guidelines did. A rationale why the guidelines did not give the desired result was identified. Future research is necessary to investigate other combinations of guidelines, such as those identified as beneficial.

To be able to improve products extensive testing is required in order to find hidden flaws in the design. The earlier flaws are found the higher are the probability that they can be corrected before the product is released onto the market. If the tests could be carried out all hours of the day every day of the week, this would introduce another level of stress to the product. More stress than if the product would be tested only during working days and it may reveal issues that could be corrected to improve the product further. Although a similar test environment already exists at Whirlpool Sweden AB, there are requests to rethink and improve these tests so that the microwave ovens are tested in an environment more close to reality. This thesis will present a concept proposal of how to improve the tests. Further, the thesis will include initial construction of a machine that could perform automated tests with the ability to interpret errors and report them. In the end, the machine should press buttons on the microwave oven, look at the display with a camera, open the door and so on. The mechanics for the machine is bought, so a big part of the thesis will be electronics design. The project will include an embedded system design with a 32-bit ARM micro controller that is going to control the machine. As this part is quite big the thesis will include the hardware design, but not much programming. The hardware design of the embedded system did work as expected, without any revisions. The hardware has been verified by electrical tests and basic software to test the general functions of the hardware. In the future, the hardware needs programming and the machine has to be equipped with a mechanical finger to be able to press buttons. Keywords: Embedded system design, ARM, Cortex-M3, , Linear guide, Stepper motor.

Behavior-Driven Development (BDD) is an emerging agile development approach where all stakeholders (including developers and customers) work together to write user stories in structured natural language to capture a software application's functionality in terms of re- quired "behaviors". Developers then manually write "glue" code so that these scenarios can be executed as software tests. This glue code represents individual steps within unit and acceptance test cases, and tools exist that automate the mapping from scenario descriptions to manually written code steps (typically using regular expressions). Instead of requiring programmers to write manual glue code, this thesis investigates a practical approach to con- vert natural language scenario descriptions into executable software tests fully automatically. To show feasibility, we developed a tool called Kirby that uses natural language processing techniques, code information extraction and probabilistic matching to automatically gener- ate executable software tests from structured English scenario descriptions. Kirby relieves the developer from the laborious work of writing code for the individual steps described in scenarios, so that both developers and customers can both focus on the scenarios as pure behavior descriptions (understandable to all, not just programmers). Results from assessing the performance and accuracy of this technique are presented.Master of Science

This paper deals with CUSUM tests based on
grouped or classified observations. The computation of average
run length is reduced to that of solving of a system of simultaneous
linear equations. Moreover a corresponding approximation
based on the Wald approximations for characteristics of sequential
likelihood ratio tests is presented.
The effect of grouping is investigated with a CUSUM test
for the mean of a normal distribution based on F-optimal
grouping schemes. The considered example demonstrates that
hight efficient CUSUM tests can be obtained for F-optimal
grouping schemes already with a small number of groups.

Testning är en nödvändig men kostsam del av mjukvaruutveckling. Test utförs på olika abstraktionsnivåer och kan vara manuella eller automatiserade. På lägsta abstraktionsnivå, enhetsnivå, är automatiserad testning vanligt och relativt okomplicerat, medan systemtester är svårare att automatisera. I synnerhet gäller detta tester på ett grafiskt användargränssnitt (GUI) som kräver speciella verktyg. Triona vill undersöka möjligheterna att automatisera regressionstester från GUI:t av sin produkt C-Load, en molnbaserad webbtjänst för avtalsbaserad transportbokning. Det primära syftet med denna fallstudie är att med en anpassad urvalsprocess utvärdera ett möjligt verktyg i förhållande till C-Load-förvaltningens förväntningar på automatiserad GUI testning (AGT) och att utifrån resultatet föreslå hur C-Loadförvaltningen kan gå vidare med val av verktyg för AGT. För att uppfylla syftet användes litteraturstudier, intervjuer och observationer av praktiska test. Verktyg för GUI-testning kan delas in i tre huvudkategorier: skriptbaserade, modellbaserade och skriptlösa. Baserat på tidigare forskning drogs slutsatsen att ett skriptbaserat verktyg där koden i testskripten skrivs manuell bäst passar C-Loadförvaltningens krav och förutsättningar. Det mest använda verktyget av denna typ, Selenium WebDriver, utvärderades kvalitativt gentemot identifierade krav. Av tidigare forskning framgår att vanliga utmaningar med skriptbaserade GUI-tester är att arbetsinsatsen för att skapa och underhålla testskript är stor och att testen kan vara opålitliga. Dessa problem framkom också i studiens intervjuer och observationer. Slutsatsen är att det vore möjligt att automatisera regressionstester av C-Load med hjälp av Selenium Webdriver, och att det på sikt skulle kunna frigöra tid. Initialt krävs dock en omfattande insats för att implementera automatiserade tester i förvaltningen och Selenium Webdriver uppfyller bara delvis C-Load-förvaltningens förväntningar på AGT. C-Load-förvaltningen rekommenderas att utvärdera fler verktyg innan beslut fattas. I en kommande urvalsprocess bör Triona beakta hur väl olika verktyg fungerar i förhållande till moderna webbramverk.Testing is a necessary but costly part of software development. Tests are performed at different abstraction levels and can be either manual or automated. On the lowest level of abstraction, where unit testing is performed, automated testing is commonplace and relatively uncomplicated, whereas system testing is more difficult to automate. This is especially true for GUI-testing, which requires special tools. Triona wished to investigate possibilities to automate regression testing of the GUI for its C-load product, which is a Cloud-based web-service for contract-based transport booking. The purpose of this case study was to evaluate one tool for automated GUI-testing (AGT) against the C-Load team’s expectations on AGT, and based on the result recommend Triona how to proceed in the process of implementing AGT. Literature studies, observations and interviews were conducted to fulfil the purpose. GUI-testing tools can be classified into three categories: script-based, model-based and scriptless. One conclusion was that a script-based tool, where test scripts are manually coded would best suit Triona’s needs. The most used tool in that category, Selenium WebDriver, was tested and evaluated against requirements. Prior research shows that common challenges encountered when using script-based GUItests are the workload required to create and maintain test scripts and that the tests can deliver inconsistent or “flaky” results. These challenges were confirmed during our analysis. Our conclusion is that it is possible to automate C-Load regression tests with Selenium WebDriver, and that it would eventually free up time. However, a considerable effort is initially required to implement automated testing. Selenium Webdriver only partly fulfills the C-Load team’s expectations on AGT. Before a decision is taken, the C-Load team should evaluate more tools. When evaluating tools for AGT, Triona should take note that Selenium Webdriver can be deficient when it comes to testing applications based on modern web frameworks.

A utilização desta abordagem no ciclo de desenvolvimento de uma aplicação web traz algumas vantagens, como ser necessário gerar manualmente apenas o modelo de comportamento de cada funcionalidade da aplicação, (pois os demais artefatos são gerados automaticamente), consumindo menos tempo e estando menos sujeitos a erros, além de prevenir diferentes interpretações dos requisitos pelos stakeholders, desenvolvedores e testadores. O tempo despendido na especificação dos modelos é compensado pelo tempo economizado com a geração dos cenários e do código de testes.The testing activity throughout software development is fundamental to the pursuit of software quality and reliability, finding faults to be removed. However, despite its importance, software testing is often an underutilized phase in software development. Moreover, tests are proved to be expensive, difficult and problematic when not done in the appropriate way. A new paradigm for software testing is model-driven testing (MDT), which can be defined as software testing where test cases are derived from a model that describes some aspects of the system being tested, such as behavior, for example. This description, often using UML diagrams and/or its profiles, can be processed to produce a set of test cases. Software specifications based on usage scenarios expressed by appropriate UML diagrams are considered significant and effective, because they describe the system’s requirements from an intuitive and visual perspective. Thus, they can be used for the description of acceptance tests, which validate that the system meets user requirements. These specifications also facilitate the automation of this kind of test. Test automation can decrease time spent on testing, thereby reducing the cost of this activity. Thus, this work proposes an approach for automated generation of acceptance tests from U2TP (the UML 2.0 test profile) diagrams for web applications, based on behavior driven development (BDD) paradigm, obtaining acceptance scenarios and executable test code supported by an acceptance testing automation framework. This approach was applied on an actual development environment, by means of an experiment. Using this approach in an web application development cycle has some advantages, such as being required only to manually generate the model of behavior of each application functionality (because other artifacts are generated automatically), thus being less time consuming and less prone to errors, and preventing different interpretations of requirements by stakeholders, developers and testers. The time spent at the models’ specification is compensated by the time saved with the generation of scenarios and test code.

Chaque année, plus de 150 000 décès sont associés aux cancers épithéliaux de l’ovaire dans le monde, notamment en raison du développement d’une résistance à la chimiothérapie. Environ la moitié de ces cancers présentent des altérations moléculaires provoquant une déficience de la réparation de l’ADN par recombinaison homologue (HRD) qui les sensibilise à l’action des inhibiteurs de la protéine PARP (PARPi). A ce jour, il n’existe pas de test capable d’appréhender le phénotype HRD dans sa globalité, limitant ainsi l’accès à ces traitements. Dans ce contexte, nous avons entrepris de mettre au point des tests fonctionnels basés sur l’utilisation d’explants tumoraux tranchés puis sur l’utilisation d’organoïdes tumoraux dérivés de tumeurs ovariennes de patientes chimio-naïves ou antérieurement traitées. La culture d’explants s’est révélée inappropriée pour la réalisation de ces tests et nous avons alors focalisé nos travaux sur les organoïdes tumoraux. Ces derniers ont été exposés au carboplatine (traitement de 1e ligne) et à deux inhibiteurs de PARP (l’olaparib et le niraparib) utilisés en traitement d’entretien. En parallèle, nous avons collecté les données cliniques des patientes (survie, intervalle sans platine, RECIST, traitements) afin d’évaluer le potentiel prédictif de ces modèles. Les organoïdes tumoraux établis ont répondu de façon hétérogène aux différents médicaments testés, et nos résultats montrent que les tests réalisés sur les organoïdes sont capables d’identifier des patientes présentant un niveau de résistance élevé au carboplatine, suggérant que ce test fonctionnel pourrait présenter un intérêt prédictif vis-à-vis de ce médicament. Concernant le potentiel prédictif des organoïdes vis-à-vis des PARPi, des profils de sensibilité variés ont été identifiés, mais la corrélation avec la réponse clinique reste à établir par des études menées sur des échantillons de tumeurs issus de patientes traitées par ces médicamentsWorldwide each year, more than 150 000 women die from epithelial ovarian cancer largely due to emergence of resistance to chemotherapy. Approximately half of these cancers display molecular alterations that cause deficiency of DNA repair via homologous recombination (HRD), which confer sensitivity to PARP protein inhibitors (PARPi). To date, there is no test capable of fully identifying the HRD phenotype, thus limiting access to these treatments. In this context, we are developing functional assays based on the use of tumor explant slices and then, on the use of tumor organoids derived from ovarian tumors of chemotherapy-naive or previously treated patients. The culture of explants was unsuitable for this application and we then focused our work on tumor organoids. Tumor organoids were exposed to carboplatin (first-line treatment) and two PARP inhibitors (olaparib and niraparib) used for maintenance therapy. In parallel, we collected clinical data from patients (survival, platinum-free interval, RECIST, treatments) to evaluate the predictive potential of these models. The established tumor organoids responded heterogeneously to different drugs, and our results show that the organoid-based assay is capable of identifying patients highly resistant to carboplatin, suggesting that this functional assay could have a predictive value for patients treated with carboplatin. Regarding the potential of organoids in predicting PARPi response, multiple sensitivity profiles have been identified, but the correlation with clinical response has yet to be determined by studies conducted on tumor samples from patients treated with these drugs

Load testing remains the most integral part of testing and measuring the performance of Large Scale Software Systems (LSS). During the course of a load test, a system under test is closely monitored, resulting in an extremely large amount of logging data, e.g., Performance counters logs. The performance counter log captures run-time system properties such as CPU utilization, disk I/O, queues, and network traffic. Such information is of vital interest to performance analysts. The information helps them to observe the system’s behavior under load by comparing it against the documented behavior of a system or with expected behavior. In practice, for LSS, it is impossible for an analyst to skim through the large amount of performance counters to find the required information. Instead, analysts often use ‘rules of thumb’. In a LSS, there is no single person with complete system knowledge. In this thesis, we present methodologies to help performance analysts to 1) more effectively compare load tests to detect performance deviations, which may, lead to Service Level Agreement (SLA) violations and 2) provide them with a smaller and manageable set of important performance counters to assist in the root cause analysis of the detected deviations.
We demonstrate our methodologies through case studies based on load test data obtained from both a large scale industrial system and an open source benchmark system. Our proposed methodologies can provide up to 89% reduction in the set of performance counters while detecting performance deviations with few false positives (i.e., 95% average precision).Thesis (Ph.D, Computing) -- Queen's University, 2013-08-28 23:04:58.774

The purposes of this study were to investigate the relationship between maximum oxygen uptake and 1.5 mile run/walk, 1600 meter run/walk and 12-minute run/walk. Regression equations were obtained from the relationship between oxygen uptake and run/walk test. Fifty-four male university students (age 20.15 ± 0.76 yrs; body height 173.02 ± 4.60 cm; body weight 63.99 ± 6.89 kgw) were recruited in this study. The results showed that 12-minute run/walk was significantly correlated with maximum oxygen uptake, compared with 1.5 mile run/walk, and 1600 meter run/walk (correlation coefficient r=0.897). This study provided new best regression equations to predict maximum oxygen uptake from the run/walk tests. These findings will provide the guidelines of training program design for the coaches and the reference for the research.

As software complexity grows so does the size of automated test suites that enable us to validate
the expected behavior of the system under test. When that occurs, problems emerge for
developers in the form of increased effort to manage the test process and longer execution time
of test suites.
Manual managing automated tests is especially problematic, as the recurring costa of guaranteeing
that the automated tests (e.g.: thousands) are correctly configured to execute on
the available test environments (e.g.: dozens or hundreds), on a regular basis and during the
products lifetime may become huge, with unbearable human effort involved. This problem increases
substantially when the system under test is one highly configurable product, requiring
to be validated in heterogeneous environments, especially when these target test environments
also evolve frequently (e.g.: new operating systems, new browsers, new mobile devices, ...).
Being an integral part of software development, testing needs to evolve and break free from
the conventional methods. This dissertation presents a technique that extends one existent
algorithm to reduce the number of test executions, and extend it, enabling to perform the test
case distribution over multiples heterogeneous test environments.
The development, implementation and validation of the technique presented in this dissertation
were conducted in the industrial context of an international software house. Real development
scenarios were used to conduct experiments and validations, and the results demonstrated that
the proposed technique is effective in terms of eliminating the human effort involved in test
distribution.À medida que a complexidade do software aumenta o mesmo acontece com a dimensão das suites de testes automizados que permitem validar o comportamento esperado do sistema que está a ser testado. Quando isso ocorre, aparecem problemas para os programadores sob a forma de aumento de esforço necessário para gerir o processo de teste e maior tempo de execução das suites de teste. Gerir manualmente milhares de testes automatizados é especialmente problemático uma vez que os custos recorrentes de garantir que os testes automatizados (ex: milhares) estão corretamente configurados para executar nos ambientes de testes disponíveis (ex: dezenas ou centennas), durante o tempo de vida dos produtos pode tornar-se gigantesco. Este problema aumenta substancialmente quando o sistema que está a ser testado é um produto altamente configurável, precisando de ser validado em ambientes heterogéneos, especialmente quando também estes ambientes destino de testes também evoluem frequentemente (ex: novos sistemas operativos, novos browsers, novos devices móveis, ...). O tempo de execução destas suites de testes torna-se também um problema enorme, dado que não é viável executar todos as suites de testes em todas as configurações possiveis. Sendo uma parte integral do desenvolvimento de software, a forma de testar precisa de evoluir e libertar-se dos métodos convencionais. Esta dissertação apresenta uma técnica que estende um algoritmo existente que permite reduzir o número de execuções de testes, e estende-o, permitindo fazer a distribuição de casos de teste sobre múltiplos ambientes de teste heterogéneos. O desenvolvimento, implementação e validação da técnica proposta na presente dissertação foram conduzidos no contexto industrial de uma empresa internacional de desenvolvimento de software. Foram utilizados cenários de desenvolvimento de software reais para conduzir experiências e validações, e os resultados demonstraram que a técnica proposta é eficaz em termos de eliminar o esforo humano envolvido na distribuição de testes.

In recent years, automotive engineering becomes more challenging and complex than previous years because of the innovation that transformed the cars powertrain system. By the quick developing of the automotive systems and increasing the consumer demand for Hybrid Vehicles (HV), Electric Vehicles (EV) and Autonomous cars, authenticity and security of engine systems
are an essential part. The Hybrid Electric Vehicle structure contained several system sections like Electric Motor, Inverter, DC-DC Converter, etc. For testing this device, OEM’s are providing a special automotive standard norm (these norms are individually defining by automotive companies as LV124/123/148) which used for simulates variety of the electrical disturbances and monitoring the system behavior. This standard profile applies, simulates and
records by EM Autowave system. Electrical tests have been done for a long time manually. Manual testing takes a huge amount of time, money and human resources. Based on the facts, the thesis purpose is to provide the
automated system test for supporting test case execution on the HEV test bench, and offline classification independent of the test bench. This scope of the project will be developed by adapting automation library which is going to equip new features for automation system tool.
On the other hand, in order to conform the test simulator and their communication system, a device file is implemented for loading and testing the electrical profiles on the test bench system. In addition, automated classification and evaluation used Matlab functions and the test result will be provided as plots which makes differential discovering very easier.

Purpose: First I compare the body mass index and VO2max between elementary school boys and girls .Second, I explore the correlation between 800m run walk, PACER, gradually step test and VO2max. Third,I develop the regressive equation to predict VO2max . Method:Subjects are 22 boys (age : 11.76.31years old ) and 28 girls ( age : 11.63 .26 years old )who are 6th grade elementary school students. All subjects perform 800m run/walk , PACER , gradually step test , and VO2max test. Independent samples t-test is used to determine differences between boys and girls, intraclass coefficient with one-way ANOVA model is used to determine the test-retest reliability of the three field tests, Pearson`s product-moment correlation is used to determine the reationship between three field tests and VO2max test., the stepwise regression analysis is used to develope the equation to predict VO2max. The significant level is set at α=.05. Results: (1)there is no difference on body mass index, but a significant difference on VO2max between boys and girls; (2)significantly high correlations between 800 run/walk, PACER, gradually step test and VO2max were found in all subjects(r＝－.72、68、75 , p＜.05 ). Three regression models predicting VO2max are established as following: (a)VO2max(ml．kg-1．min-1)=90.81－.10．800m run/walk(sec)－5.53．sex(boy＝0, girl=1)－1.69．BMI(kg/m2)＋.37．weight(kg); (b)VO2max(ml．kg-1．min-1)=56.10＋0.28．PACER(laps)－2.01．BMI(kg/m2)－5.03．sex(boy＝0, girl=1)＋0.47．weight(kg); (c)VO2max(ml．kg-1．min-1)=49.26＋0.02．step(sec)－4.98．sex(boy＝0, girl=1)－1.77．BMI(kg/m2)＋0.41．weight(kg). Conclusions: (1) 800 run/walk, PACER and gradually step test provid accurate predictions of VO2max (2)The study suggests that 800 walk/run test is the best predictor of the VO2max for all subjects; if 800 walk/run test can not be performed in bad weather or narrow places, Gradually Step Test can be used instead.

There exist numerous approaches to index either spatio-temporal or high-dimensional data. None of them is able to efficiently index hybrid data types, thus spatio-temporal and high-dimensional data. As the best high-dimensional indexing techniques are only able to index point-data and not now-relative data and the best spatio-temporal indexing techniques suffer from the curse of dimensionality, this thesis introduces the Spatio-Temporal Pyramid Adapter (STPA). The STPA maps spatio-temporal data on points, now-values on the median of the data set and indexes them with the pyramid technique. For high-dimensional and spatio-temporal index structures no generally accepted benchmark exists. Most index structures are only evaluated by custom benchmarks and compared to a tiny set of competitors. Benchmarks may be biased as a structure may be created to perform well in a certain benchmark or a benchmark does not cover a certain speciality of the investigated structures. In this thesis, the Interface Based Performance Comparison (IBPC) technique is introduced. It automatically generates test sets with a high code coverage on the system under test (SUT) on the basis of all functions defined by a certain interface which all competitors support. Every test set is performed on every SUT and the performance results are weighted by the achieved coverage and summed up. These weighted performance results are then used to compare the structures. An implementation of the IBPC, the Performance Test Automation Framework (PTAF) is compared to a classic custom benchmark, a workload generator whose parameters are optimized by a genetic algorithm and a specific PTAF alternative which incorporates the specific behavior of the systems under test. This is done for a set of two high-dimensional spatio-temporal indices and twelve variants of the R-tree. The evaluation indicates that PTAF performs at least as good as the other approaches in terms of minimal test cases with a maximized coverage. Several case studies on PTAF demonstrate its widespread abilities.

YesObjectives: To develop a logistic regression model to predict the risk of sepsis following emergency medical admission using the patient’s first, routinely collected, electronically recorded vital signs and blood test results and to validate this novel computer-aided risk of sepsis model, using data from another hospital. Design: Cross-sectional model development and external validation study reporting the C-statistic based on a validated optimized algorithm to identify sepsis and severe sepsis (including septic shock) from administrative hospital databases using International Classification of Diseases, 10th Edition, codes. Setting: Two acute hospitals (York Hospital - development data; Northern Lincolnshire and Goole Hospital - external validation data). Patients: Adult emergency medical admissions discharged over a 24-month period with vital signs and blood test results recorded at admission. Interventions: None. Main Results: The prevalence of sepsis and severe sepsis was lower in York Hospital (18.5% = 4,861/2,6247; 5.3% = 1,387/2,6247) than Northern Lincolnshire and Goole Hospital (25.1% = 7,773/30,996; 9.2% = 2,864/30,996). The mortality for sepsis (York Hospital: 14.5% = 704/4,861; Northern Lincolnshire and Goole Hospital: 11.6% = 899/7,773) was lower than the mortality for severe sepsis (York Hospital: 29.0% = 402/1,387; Northern Lincolnshire and Goole Hospital: 21.4% = 612/2,864). The C-statistic for computer-aided risk of sepsis in York Hospital (all sepsis 0.78; sepsis: 0.73; severe sepsis: 0.80) was similar in an external hospital setting (Northern Lincolnshire and Goole Hospital: all sepsis 0.79; sepsis: 0.70; severe sepsis: 0.81). A cutoff value of 0.2 gives reasonable performance. Conclusions: We have developed a novel, externally validated computer-aided risk of sepsis, with reasonably good performance for estimating the risk of sepsis for emergency medical admissions using the patient’s first, electronically recorded, vital signs and blood tests results. Since computer-aided risk of sepsis places no additional data collection burden on clinicians and is automated, it may now be carefully introduced and evaluated in hospitals with sufficient informatics infrastructure.

Les outils de programmation sont des programmes informatiques qui aident les humains à programmer des ordinateurs. Les outils sont de toutes formes et tailles, par exemple les éditeurs, les compilateurs, les débogueurs et les profileurs. Chacun de ces outils facilite une tâche principale dans le flux de travail de programmation qui consomme des ressources cognitives lorsqu’il est effectué manuellement. Dans cette thèse, nous explorons plusieurs outils qui facilitent le processus de construction de systèmes intelligents et qui réduisent l’effort cognitif requis pour concevoir, développer, tester et déployer des systèmes logiciels intelligents. Tout d’abord, nous introduisons un environnement de développement intégré (EDI) pour la programmation d’applications Robot Operating System (ROS), appelé Hatchery (Chapter 2). Deuxièmement, nous décrivons Kotlin∇, un système de langage et de type pour la programmation différenciable, un paradigme émergent dans l’apprentissage automatique (Chapter 3). Troisièmement, nous proposons un nouvel algorithme pour tester automatiquement les programmes différenciables, en nous inspirant des techniques de tests contradictoires et métamorphiques (Chapter 4), et démontrons son efficacité empirique dans le cadre de la régression. Quatrièmement, nous explorons une infrastructure de conteneurs basée sur Docker, qui permet un déploiement reproductible des applications ROS sur la plateforme Duckietown (Chapter 5). Enfin, nous réfléchissons à l’état actuel des outils de programmation pour ces applications et spéculons à quoi pourrait ressembler la programmation de systèmes intelligents à l’avenir (Chapter 6).Programming tools are computer programs which help humans program computers. Tools come in all shapes and forms, from editors and compilers to debuggers and profilers. Each of these tools facilitates a core task in the programming workflow which consumes cognitive resources when performed manually. In this thesis, we explore several tools that facilitate the process of building intelligent systems, and which reduce the cognitive effort required to design, develop, test and deploy intelligent software systems. First, we introduce an integrated development environment (IDE) for programming Robot Operating System (ROS) applications, called Hatchery (Chapter 2). Second, we describe Kotlin∇, a language and type system for differentiable programming, an emerging paradigm in machine learning (Chapter 3). Third, we propose a new algorithm for automatically testing differentiable programs, drawing inspiration from techniques in adversarial and metamorphic testing (Chapter 4), and demonstrate its empirical efficiency in the regression setting. Fourth, we explore a container infrastructure based on Docker, which enables reproducible deployment of ROS applications on the Duckietown platform (Chapter 5). Finally, we reflect on the current state of programming tools for these applications and speculate what intelligent systems programming might look like in the future (Chapter 6).
