Visualiseringsverktyg för Sykedjor

Norrå, Ulrik, Angerbjörn, David January 2012 (has links)
This thesis has been done in order to ease the process of drawing schematics of electrical wiring. The need arose after demand from the government due to a series of incidents that took place during the revision of the nuclear power plant in year 2009. The task of the project has been to create a computer program that can generate a graphical representation of the electrical components relations. The basis for the program has been an example of how the client wants the graphical representation to look. During the course of the project weekly meetings have occured in which the client has reviewed the work. The result of the project is a program written in Visual Basic Applications that can be run in Microsoft Excel. The program is capable of generating graphics for a majority of the cases. Since the program is written in Visual Basic Applications it is possible to run it on almost any computer that has the Microsoft Office suite installed. The program is straight forward, has a built in user manual and a step-by-step guide in order to make it easy to use.

Automation of Offline Programming for Assembly and Welding Processes in CATIA/DELMIA using VBA

Müller-Wilderink, Henrik January 2021 (has links)
Programming industrial robots for welding or part manipulation tasks is a time-consuming and complicated process, resulting in companies not able to implement robot systems and exploit their advantages. To reduce the time needed for programming, research is looking into ways to automate this process and reduce manual labour.In this thesis a concept for automating the programming process of industrial robots was investigated using EXCEL VBA and CATIA/DELMIA. It was done for an industrial grating model of varying sizes and configurations, resulting in a time reduction of 99% compared to manual creation. For this, the model was first automatically created from scratch for the required configuration and afterwards a robot motion was created fully automatically. The concept and modelling approach is described, and the automation approach detailed. Finally, the results are analysed and discussed.

AUTOMATIC DESIGN OF WIRING PATTERN FOR CAR SEAT HEATERS

Abdollahifakhr, Hamon, Sengul, Ceyhun January 2010 (has links)
This projects aims to develop design automation in product development. Design automation causes increase in producibility and decrease in product cost and manufacturing lead time. The study at hand is proposed to provide a new method and to introduce procedure to the design of wiring pattern for a car seat heater for Kongsberg Automotive, KA. KA is a Norwegian company and a global provider of engineering, design, and manufacture for seat comfort, driver and motion control systems, fluid assemblies, and industrial driver interface products. The method that currently is used in the company to create a wiring pattern is neither sufficient enough nor automated. In order to design the wiring pattern, at first procedure is handled by the designer. Secondly, car seat heater 2D layout is imported and then, the dimensions of the elements are defined as constraints. Then VBA codes are opened and the program is run. The result will be a wiring pattern in different 2D layouts. To make the design process easier, we have modeled five different layouts; wiring pattern of one element, two elements, three elements, five elements (with two back sides) and one element trapezoidal 2D layout. The algorithm written in VBA (Visual basic for application) creates the pattern according to the dimensions of the elements which are used as inputs to define constrained parameters. The created macros are simple to use and easy to modify, independent from the programming knowledge. The user is only responsible with parameter input and running the program. The solution gives wiring pattern for a car seat heater.

Building a multi-tier enterprise system utilizing visual Basic, MTS, ASP, and MS SQL

Poti Allison, Tamara S. January 2001 (has links)
Multi-tier enterprise systems consist of more than two distributed tiers. The design of multi-tier systems is considerably more involved than two tier systems. Not all systems should be designed as multi-tier, but if the decision to build a multi-tier system is made, there are benefits to this type of system design. CSCources is a system that tracks computer science course information. The requirements of this system indicate that it should be a multi-tier system. This system has three tiers, client, business and data. Microsoft tools are used such as Visual Basic (VB) that was used to build the client tier that physically resides on the client machine. VB is also used to create the business tier. This tier consists of the business layer and the data layer. The business layer contains most of the business logic for the system. The data layer communicates with the data tier. Microsoft SQL Server (MS SQL) is used for the data store. The database containsseveral tables and stored procedures. The stored procedures are used to add, edit, update and delete records in the database. Microsoft Transaction Server (MTS) is used to control modifications to the database. The transaction and security features available in the MTS environment are used. The business tier and data tier may or may not reside on the same physical computer or server. Active Server Pages (ASP) was built that accesses the business tier to retrieve the needed information for display on a web page. The cost of designing a distributed system, building a distributed system, upgrades to the system and error handling are examined.Ball State UniversityMuncie, IN 47306 / Department of Computer Science

En jämförande studie av Visual C++, C# och VB.NET / A Comparative Study of Visual C++, C# and VB.NET

Krisell, Magnus January 2005 (has links)
Programmeringsspråken Visual C++, C# och VB.NET (Visual Basic.NET) jämförs, med tyngdpunkt på en praktisk jämförelse av fyra exempelapplikationer. Exempelapplikationen WordCount visar att Visual C++ har förutsättningar förbäst prestanda, men att även C# och VB.NET ger helt godtagbar prestanda. Valet av färdiga klasser är viktigare än språket. Ett olämpligt val kan göra prestandan mycket sämre än förväntat, medan den allra bästa prestandan ofta erhålls med en egen implementering. Applikationen FFT visar att flyttalsprestandan är bättre i C# än i VB.NET. Applikationen Clock visar att Visual C++ har en viss fördel i sitt färdiga ramverk för traditionella dokumentbaserade Windowsapplikationer. C# och VB.NET vinner över Visual C++ i nästan alla övriga avseenden. De ger mindre mängd kod och tillhandahåller ny funktionalitet — som egenskaper, händelser, attribut och ett mycket omfattande klassbibliotek — som gör programmeringen enklare och mindre känslig för buggar och säkerhetshål. Valet mellan C# och VB.NET bör avgöras av projekttyp, företagskultur och utvecklarens individuella preferenser.
