Detta projekt drevs på uppdrag av Flex Datasystem som behövde en vidareutveckling av deras aktuella hemsida. Här finns bland annat möjlighet att direkt ladda ner uppdateringar för kundernas program. Problemet var att hemsidan inte innehöll någon information om uppdateringarna. Kunderna måste då vända sig direkt till supporten för att få information om vad som har åtgärdats. Det här projektet gick ut på att utveckla en funktionalitet som, med automatik, publicerar information om varje uppdatering. Informationen skulle föras över från Flex Datasystems interna system till kundzonen med hjälp av en webbtjänst. Utvecklingen skedde mestadels i Visual Studio miljö. I projektets början infördes några nya funktioner till företagets interna system. Därefter skapades själva webbtjänsten och till sist lades en ny sida till på företagets hemsida som använde sig av denna webbtjänst. De krav som ställdes upp för det här projektet blev uppfyllda. Det visade sig att användandet av en webbtjänst fungerade mycket bra för det här ändamålet.

What do you do if you are implementing a new fieldbus protocol in your embed- ded industrial system and want to test it? This was the question that a group of engineers at ABB Corporate Research was asking themselves. Normally, the easiest way would probably be to buy a matching device supporting the same protocol and hook it up to the system. You might also need some equipment to listen in on the traffic between the two, so you’d need to buy that too. But what if you are working with a limited budget? Or what if this protocol is fairly new, and matching devices are hard to find? Or what if you want to test cases that can’t normally be achieved with normal usage? Normally, with traditional fieldbus standards, this could be complicated. You would probably need an additional sample of your new system, with some cus- tom made test code, and use this to test the original system. This is not a bad method, but this report will give an example of the new possibilities that comes with the new Ethernet base fieldbus standards emerging on the market today. It will highlight the possibility to create a test tool for your industrial system to use on a standard PC. ”Why?” you might ask. The report suggests that this solution is cheap, fast and flexible. First of all, no special hardware was needed, which had a posi- tive impact on cost. The only thing used was a PC and some standard office equipment. Second, once the test tool was created, new test cases was really fast and easy to make. The test tool was designed to function as a general framework for creating dynamic test sequences based on Ethernet. Third, the tool is flexible enough to test a lot of different cases, even cases not allowed by the standard. It made it possible to test cases that would have required the use of several samples of test system simultaneously to work. Also, because Ethernet is such a well known standard, there are a lot of existing software tools at your disposal. For example, free software for capturing and analyzing the test results was used during the tests. Furthermore, since the test tool was designed to be easily extendable to handle more protocols, it is even more flexible and useable for future similar problems.

This is a report founded on a project by Atlas Copco called NYSTAB.  The application Nystab is a calculation program that can calculate the stability of the rockdrill-rigs made by Atlas Copco. The original version of Nystab is stored in a database from 1997 and the code is made in an old version of Visual Basic. My assignment was to develop the application in to a newer programming environment and make it last better in the upcoming years. The software I decided to use to accomplish this project is C# .NET in Visual Studio and Microsoft Access 2010. All the code is written in C# with some insertions from ADO.NET which helped me to easier connect the code with the database. The coding part was split into two pieces; the first was to develop the application scale done with Windows Forms, the second was to write the code for calculations in the application. This report will cover some methods of how you can connect the database to an application and why Microsoft Access was the best alternative for database in this project. The report also shows the difference between VB and C# to get an overview on why  people today often chose to develop their applications in C#. Exceptions is a big part of the handling of errors or search for errors in the application and the report shows concrete examples on how you use exceptions in different situations and why. / Detta är en rapport grundat på ett projekt för Atlas Copco vid namn NYSTAB. Programmet är ett beräkningsprogram som kan beräkna stabiliteten av Atlas Copcos borr-riggar, det ursprungliga programmet ligger på en databas från 1997 och är kodat i en gammal variant av Visual Basic. Mitt uppdrag var att utveckla programvaran till en nyare miljö med bättre framtidssäkerhet och kompabilitet samt att sätta mig in i Visual Basic miljön för att kunna få fram information om hur dessa stabilitetsberäkningar utförs. Den programvara jag har valt att arbeta i under detta projekt är C# .NET i Visual studio 2010 samt Microsoft Access 2010. All programmering är gjord i C# med inlägg från ADO.NET som hjälpt mig att koppla programmet med databasen. Programmeringen var uppdelad i två delar; dels skulle jag utforma en applikation som jag gjort med hjälp av Windows Forms och dels var det programmeringen av beräkningarna. Rapporten tar upp metoder att koppla databaser mot applikationer och varför Microsoft Access är den bästa databasen till just det här arbetet. Rapporten tar även upp skillnader mellan VB och C# för att få en överblick till varför man idag ofta väljer att programmera i C#. Exceptions är en stor del i felhanteringen eller felsökningsfunktionen i applikationen och rapporten tar upp konkreta exempel på hur man använder sig av exceptions i olika situationer och varför man gör detta.

The C Navigational System (CNS) is a proposed programming environment for the C programming language. The introduction covers the major influences of programming environments and the components of a programming environment. The system is designed to support the design, coding and maintenance phases of software development. CNS provides multiple views to both the source and documentation for a programming project. User-defined and system-defined links allow the source and documentation to be hierarchically searched. CNS also creates a history list and function interface for each function in a module. The final chapter compares CNS and several other programming environments (Microscope, Rn, Cedar, PECAN, and Marvel).

In 2019, the Covid-19 pandemic struck the world, creating a need for social distancing to stop the spreading of the virus. This report will discuss and cover how a simulation was implemented in the game engine Unity that simulates human movement-patterns, which in turn will help with spreading people out in public areas. To be able to do this accurately, research was made about which behaviours can be of importance to get as realistic a representation of human movements as possible. The performed research showed that some contributing factors to get a realistic result includes how many destinations (e.g. in a Supermarket, a destination would be a shelf with wares) a human usually visits during a shopping trip to a supermarket. This is something that was quickly realized and could be used and implemented in the simulation, as it directly affects how long each human stays in the store, which in the long run makes crowds, and places where they form, more realistic. When the simulation was finished, a Google Forms was created, which were spread in numerous different groups on Facebook and Reddit, in which a total of 60 participants were registered. This quantitative research gave a good understanding of how the project had turned out and what could be improved. The results were very promising, and more or less what was hoped for. There is still room for further improvements, which are all mentioned in the chapter “Further Research” of this report. One example that is mentioned here is whether or not collisions between our simulated humans matter enough to make a difference to the end result. It is argued that it does not, but this is something one should perform further studies on.
