Restoranų informacinės sistemos modelis ir programinė realizacija / Restaurant information system model and implementation

Dzenkauskas, Paulinas 16 January 2006 (has links)
The recent stabilization of the Internet is now driving easy aspect of life into an Internet presence and the accompanying e-commerce solutions. In the coming years, the Internet will see growth in numbers unlike the world has ever seen. E-commerce has built itself with this in mind and is making every effort it can to seize the strongest position possible. The idea of e-restaurant extends the restaurant to the web and therefore to the home of customers. It provides the basic services, such as reservation, meal selection, and recommendation. The most appealing thing we found about e-restaurant is its online reservation service. On customer side, customers can take as much time as their need to choose table positions, search menu items, and investigate menu items through pictures, descriptions and feedbacks on e-restaurant's web page before making reservations. Moreover, e-restaurant provides 24-hour reservation service which is difficult for conventional restaurants to provide. On restaurant side, on-line reservation reduces human errors which are not uncommon in reservations by phone. On-line reservation also frees the staff of e-restaurant from repetitive data entry and paperwork. This allows e-restaurant to redirect labor used for back office tasks to front of the house tasks to improve customer service, which is the heart of restaurant business. The Management of e-restaurant can access immediate and up to date business critical data to adjust management strategy in a... [to full text]

Vartotojiškoji ir mokomoji fraktalinių vaizdų kūrimo sistema / Concumer and Educational Flame Fractal Development System

Urbonavičius, Gytis 18 January 2006 (has links)
"Fraktalai" is a program for creating and editing IFS and Flame Fractal parameters. Once a nice fractal has been found the parameters can be exported to IFS for use with my Iterated Function Systems coloring algorithm. The IFS files that it creates can also be viewed in other fractal programs. Iterated Function Systems is used in image compression. It also becomes very popular as a way of producing fractal images. "Fraktalai" only makes a distinction between Iterated Function Systems and Flame Fractals when loading and saving parameters. The algorithm that generates random fractals is designed to create reasonably interesting parameters but it has no sense of beauty, so you will probably want to make some adjustments. The supplied gradients were created from image files using a special algorithm (you may have noticed the names of a few famous paintings). This sort of gradient looks very nice with Flame Fractals, and "Fraktalai" has the ability to create similar gradients from BMP or JPEG images.

Valuckienė, Loreta 31 May 2006 (has links)
SUMMARY Informational system of elementary school community is Informational system, that accummulates and transfers information, inportant for members of school community. System works on intranet and extranet technologies base. The main demand for the system – informational system (IS) should to decrease user‘s time costs presenting end receiveing important information about the spheres of school activity. The main IS users, are administration of the school, teachers, pupils and parents of pupils. The basic IS activity spheres – information about the shcool, it‘s activity, news, links, e – diary and schedules. This document is the documentation of „Informational system of elementary school community“. The documentation reviews the stages of analysis, projecting, program realization and presented summary of user‘s documentation. In the proccess of analysis, were analysed and specified functional and non-functional requirements and limits, that determined IS should be created with the intranet and extranet technology help, using PHP and HTML programming language, InterBase data base, Macromedia Flash and Paint programs. The created IS corresponds to the model of architectural informational system of 3 levels. User‘s link – Activity‘s rules – Data base or TXT files. Informational system is safe.

Adiklienė, Asta 09 January 2007 (has links)
Theme „E-tool for teaching of economics at school”. The aim of the research is to design an e-tool, i.e. an educational tool to be applied by teachers for teaching and examination of the subject of economics. Objectives:  To create a suitable and attractive user interface;  To present the theory of economic course and task examples;  To design the examination of self-monitoring and check tests and tasks;  To store the evaluation of students by recording it in grade books;  To grant the possibility to teachers to allow their students retake tests or given tasks. Having conducted the analysis of parallel target tools, the requirements raised for the educational tool have been determined: easy installation, no particular requirements for the hardware and software; simple control features; comfortable, explicit and intuitively comprehensible user interface; informatively, explicitly, concisely and interestingly presented information. The designed e-tool, meant for teaching economics at school, is targeted to the students of higher forms and includes the theory of particular topics and task examples, self-monitoring and check tests and tasks. Assessment in grades is stored in teachers’ registers. In the event of designing the tool a lot of information was obtained with reference to programming technologies and tools that facilitate the procedure of designing and programming, as well as various attendant problems.

Matematinių išraiškų pertvarkymo programinė įranga. Lygiagretaus funkcionavimo valdymas / Software for reformation of the mathematical expressions. Parallel operation control

Vaškevičius, Vytautas 28 May 2004 (has links)
This project is a life cycle of the software for reformation of the mathematical expressions. A final product is a system, which operate integrated with Maple and MPI systems. Maple is universal mathematical software product [2], [3]. This system is required to handily input and output data, to have ability using standard functions. MPI is a service for controlling the distributed system [6], [7]. This service is required for parallel reformations of the mathematical expressions using several single-processor computers. The project goal is to design, implement and deliver to customer for usage developed product instead of current slower solutions. Exactly speed is the key non-functional requirement for the product. Current solutions exist, but the speed is unacceptable for the customer. Most solutions are universal mathematical software, which uses one single-processor computer, which is obtainable for most users. Multi-processor systems are very expensive. The product we developed is specialized, so it has high-speed reformation algorithm. Besides, our product uses cheaper solution then multi-processor system – it uses processors of intranet single-processor computers. Parallel (using all processors) performing the reformation of mathematical expressions especially reduces the total time of decision of the problem. We have been developing the system for 16 months, because the resources were limited. We have done demand analysis, collected and specified requirements, designed... [to full text]
