<p>NMD 100 is a notes and media dispensing machine, manufactured by De La Rue Ltd, located in Flen, Sweden. The customers, mainly bank offices, have expressed a need for a more comprehensive description of errors occurring from time to time in their machines. In order to acquire a BSc-degree in Computer and Electronics Technology at the University of Linköping I have carried out a diploma work, regarding new computer programs to fulfil the customers’ wishes. The machine NMD 100 is connected to its PC through handshaking. From the PC, the personnel can give orders regarding desired actions to the NMD 100. In turn, the NMD will respond to the PC. Inside the NMD, the Note Stacker is equipped with a great number of sensors. They control that the bundle of notes, delivered to the ATM customer is correct, regarding the number of notes and denomination. Notes that in any way are not immaculate will be sent to the Reject Vault. </p><p>If internal errors or warnings occur in the NMD, a code consisting of 8 digits is sent to the PC. The location of the error or warning is defined by the last 4 digits. The scope of my work is to define and present this information. For this purpose the company uses the program language C++ and the tool Borland C++ Builder 6. In particular, the program NMDW-Test is used to send commands from the PC to the NMD. After having studied the above programs, I was able to write new programmes for error detection, interface and installation. After program testing, the company accepted the result of my work.</p>

Websites today only offer simpler form of technical analysis and are not fun to use, therefore student decided to build a website that makes technical analysis a bit more fun by giving user possibility to experiment with settings for technical indicators and also see clear visible results from analysis. Student decided to build website in ASP.NET. Technical indicators for this project only consist of those who give buy and sell-signals via cross-over, no divergence or pattern finding.This project has three questions that define this project. It’s important that there is good functionality so that performing an analysis is perceived as simple, one question is therefore; what functionality for website is needed in order for analysis to be perceived as more simple?Technical analysis is a pretty complex subject and demands an interface that is perceived as easy to understand and easy to use, it’s therefore important that the interface is well designed, second question is therefore; how should the interface be designed to be user-friendly?When systems grow large they often become hard to develop and later on unmaintainable because of the accumulated complexity and dependency between classes, the code is a mess, the last question is therefore; how can the systems complexity be eased with object-oriented design principles?Jakob Nielsens ten heuristics for User Interface Design were used as inspiration for designing the interface for the website. The system design follows SOLID principles, some pattern-design were also used because pattern-design often fulfills SOLID principles or makes for pretty good solutions in regular code-problems.At the beginning of the project the student did a small research to find out what was needed in order to complete project. Work-method for project follows agile development where decisions were made on a weekly basis. The project was divided into three phases where each phase was strongly coupled to a specific area of responsibility. Prototypes for interface were made and used as a basis for the resulting interface.The project led to a working website with good functionality. Filter was considered as important in order to ease shaping of analysis because the user could more easily sort and pick stock. The student assumed that the user would want fast and easy access to their stock so portfolio management were implemented so that user could more easily get to stock that was considered as favorites. The interface follows to a big extent Jakob Nielsens ten heuristics for User Interface Design and is proven by comparing interface with principles. The same goes for design of the system, design is proven by comparing with principles, still to this day system is considered easy to continue development.Student made the conclusion that SOLID principles were very important in order for the system to maintain its health and took experience from these principles. Student became happy with the interface but more focus could’ve been given for a more interactive interface because it might’ve been perceived as more intuitive.
