Written corrective feedback is extensively used in second language writing courses. Although some think it detrimental to student learning (i.e. Truscott, 1996), much research over the last decade has proven a place for written corrective feedback in the classroom. The present report seeks to review literature on such feedback. This includes research on more recent approaches such as dynamic written corrective feedback, computer-based feedback, concordance use as feedback, and peer feedback. The report discusses pedagogical implications and areas for future research. / text

This thesis deals with distributed applications and WCF framework. The first part is based on theoretical information about distributed systems and we also concentrate on models of distributed systems. Next part describes WCF framework and key elements of WCF application. The following chapter is designated to introduce information about prime factorization. Then the knowledge from previous parts is used to create examples of service-oriented applications. In conclusion we discuss main parts of designing distributed application to solve factorization problem. Finally the comparison of distributed and dedicated application is made.

This thesis provides reflections on a practice of corrective feedback known as dynamic Written Corrective Feedback (dynamic WCF). First addressing 20 years of concerns regarding the highly-debated topic of feedback in second language (L2) writing and then outlining dynamic WCF as a pedagogical practice founded on four principles, the thesis finally introduces a recently developed handbook for instructors. This handbook presents the four foundational principles of dynamic WCF (timeliness, manageability, meaningfulness, and constancy) to first-time instructors and supports the implementation of dynamic WCF to optimize benefit and enhance manageability in written corrective feedback.

This study looks at the effectiveness of direct and indirect written corrective feedback (WCF) when using them with 26 intermediate ESL learners’ writings. The study also investigates whether giving the learners the type of feedback they preferred or less preferred would influence their actual performance. WCF, a pedagogy that is often used when helping learners improve their written accuracy, has captured researchers’ attention in recent decades. Truscott (1996) claimed that WCF is ineffective and suggested teachers should abandon it. Therefore, in the early studies, researchers concentrated on examining the effectiveness of WCF, in order to justify the value of using WCF. In recent studies, researchers have proved that WCF is effective in certain contexts, and they have also investigated the value of using different types of WCF, and the value of using it over time. Moreover, in order to help learners to improve in written accuracy, recent studies in the field have also investigated whether WCF is more effective when used on a certain type of linguistic form/structure. With respect to different types of WCF, researchers in recent decades have also paid some attention to learner preference in WCF. However, the relationship between learner preference and the value of using the type of feedback learners prefer has not yet been investigated. In essence, the relationship between learner preference and their actual performance when using the type of feedback they preferred was examined in this study. The study also aimed to look at the effectiveness of WCF over time, and to investigate whether direct feedback or indirect feedback helped learners better. Furthermore, the study also aimed to investigate whether there was a certain type of linguistic form that WCF works best with. A quantitative approach was used in this study in order to show the results more clearly, and to provide statistical evidence on each finding. The study involved questionnaires, and three writing tests: pre-test, immediate post-test, and a delayed post-test. Before the learners did the pre-test, they were asked to complete a questionnaire to select their preferred type of feedback (direct feedback or indirect feedback). Based on their preferences on feedback, they were put into different groups. Group one received direct feedback; group two received indirect feedback; group three received the feedback they preferred (indirect feedback); group four received no linguistic feedback, but general commentaries on their writing were given. The participants (twenty-six students who enrolled in a general English program at AUT University) had completed the questionnaire and the three writing tests. Findings from the study revealed that, most of the learners preferred receiving direct feedback. When examining learner performance between those who received the type of feedback they preferred and those who did not, the former did not outperform than others. However, factors like different levels of scaffolding assistance may have affected the results. Other findings from the study revealed that WCF was effective overtime, especially when using it on errors of present simple tense. The study also found that indirect feedback was more effective than direct feedback. A possible factor that appeared to influence learners’ performance was identified as learners’ motivation in learning. The results of the study contribute to an understanding of the type of feedback that is most suitable for learners at intermediate level, and on which type of linguistic form WCF can work best with. Practical suggestions for pedagogy and further research are also made.

This thesis project is about collecting usage statistics in an application, how the information can be logged and presented in a suitable way and to what purpose these statistics are used. The project is a logging service to which applications can connect and send performance and usage data. The service logs the data to a file, which can be opened in QlikView for presentation of data statistics. The resulting statistics are planned to be used for the evaluation and improvement of the client application and improvement on the end users way of working with that application. The service was implemented as a WCF service in C# and uses the logging capabilities of the Enterprise Library Logging Application Block. A WCF service is a service capable of having a variety of different applications connected to it, using different communication protocols. The result of our project is a working service prototype which logs data to file. Data generated by a test client is successfully logged by our service and its statistics is displayed in an application named QlikView.

The project discussed in this thesis was initiated by the Swedish IT company Ninetech in an effort to simplify maintenance of the company's server farm. The proposed method of simplifying maintenance was to create an Android application capable of visualizing key elements of the server farm. Since the internal information that the application should expose is of a classied nature, the whole system needs to be secured to prevent unauthorized access. This thesis describes the development of an Android application as well as a server application handling the communication between the Android application and the server farm information service. / Data visualization on Android

Det här projektet handlar om arbetet med att ta fram SPÅRA Fisk, en webbapplikation som är skapad för att hantera fisk-och vattenbrukspartier. SPÅRA Fisk skall underlätta partihanteringen för företag inom fiskbranschen, vilket innefattar nyregistrering av partier, skapande av produktionspartier, registrering av försäljning och förädling samt terminering. Produkten är framtagen i syfte att underlätta hanteringsprocessen för företag inom fiskbranschen som verkar inom EU och därmed omfattas av spårbarhetskraven som träder i kraft under slutet av 2016. Spårbarhetskraven innebär att i stort sett all handel och förädling med fisk- samt vattenbruksprodukter måste rapporteras in till Hav & Vatten myndigheten. Applikationen är skapad med responsiv design och fungerar både på dator och mobil, även om mobilversionen har mer att önska inför framtiden. Applikationen är skriven i ASP.NET och kommunicerar med en databas genom en Web Service.

When you need to assess or troubleshoot network by analysing capture file, you want it done as fast as possible and you do not always have a high-performance computer. Here comes the distributed system, which allows you to use his high computing power and lot of available memory. I introduce distributed application, which is scalable, extensible and capable of processing captured network communication and is developed for Windows platform. That provides technology, like Microsoft HPC Pack and Windows Communication foundation. The application supports multiple capture formats. In parallel system (cluster), exists database in order to save statistics and data of captured communication in order to save user's computer memory so client's application can be used for low-performance computers or make data available to a client after distributed processing.

I dagsläget ställer sig många företag frågan om man ska uppgradera sina applikationer från Dotnet Framework till Dotnet 6. Saab AB är ett av dessa företag och har därför valt att undersöka möjligheten att migrera sin MSS applikation till Dotnet 6. De vill även veta hur stort jobb det skulle innebära att migrera från Dotnet Framework till Dotnet 6. För att migrera en applikation som använder det obsoleta ramverket WCF behöver det ersättas med antingen gRPC eller CoreWCF. Då MSS använder sig av WCF kommer den här rapporten rikta sig på den sistnämnda ersättningen, CoreWCF. Baserat på resultatet är det tydligt att det kommer krävas ett stort arbete för att få över MSS till Dotnet 6. Avslutningsvis ges förslag på vidare forskning inom området.
