Lack of complex solutions covering technical aspects of technologies and theoretical aspects of information systems is felt, while new wireless technologies gain quick adoption in business. Fast spread of WiFi is followed by “WiMAX” – number of this technology based solutions is growing fast. But there is still lack of information systems models which would fit possibilities of current technologies and requests of modern business. Analysis of most popular wireless technologies is followed by conclusion, that only analysis of “WiMAX” and WiFi is logical considering native qualities of technologies analysed. Review of current information system models reveals, that decision making and expert systems can be treated as working on same model same as information and data processing systems can be also threaded. Analysis of existing information system models is fulfilled by adding qualities of wireless technologies and two new models of wireless technologies based information systems are formed. They both are based on essential models of decision making and information processing systems but use wireless technologies where its possible keeping in mind technical possibilities – in connecting input/output parts with main information systems components. These conclusions are followed by research of Lithuanian IT companies which concludes, that there is a high... [to full text]

Work analyses the possibilities of usage of information technology in civil procedure, and how it would impact some principles of civil procedure – efficiency of the process, cost-effectiveness, time-efficiency, effectiveness and other. Paper work mostly concentrates on separate issues of usage of information technology in civil procedure: preparation and service of procedural documents, usage of electronic evidence in the court process, usage of video and teleconferencing, using modern technologies to capture the process of the case, collecting all related documents of the case in electronic form, and computerizing management of courts. Separately the work discusses the impact of information technology usage in the civil procedure to the protection of personal data and right to privacy. Logical, systematical, descriptive, and analytical methods are used in the paper work, besides the work is based on the analysis of the current law and the projects of laws. Very big attention is for analysis of practice of foreign countries in the view of the considered issues, also taking into consideration the articles of some scientists.

The information system created performs the following functions: standardizes the process of failure registration and management; allows monitoring and receiving information in different sections adapted for certain groups; provides opportunity to evaluate the existing situation of provision with equipment and plan future investments within time scale; allows service of a whole group of users in one time. The information system has been created by using open source software – which enables to avoid additional investments.

Nowadays, the work of any concern or organisation that uses modern methods is highly related to computerised information system, which helps the organisation in solving and implementing various tasks that arise during its work. The prototype of Lithuanian interface software that was created during the project is dedicated to small real estate agencies to collect and manage the information on real estate objects and orders that were registered in the agency. The product suits managers of real estate agencies best. Using the following software it is possible to search through the real estate objects that are registered in the system, print the information needed, view the records, register orders, objects related to the orders and all the information related to the implementation of an order. This software will give the managers of organisations the possibility of fast comparing between the real estate objects under various criteria and to select the variants that suit the customer best. The creation of the system involved several main stages. First, it was necessary to specify the requirements for the future system. The second stage involved designing and programming of the system itself using Microsoft Visual Studio 2005 tools and Visual Basic programming language. At the end, the process involved testing of the system and writing the thorough user manual.

In security engineering and computer security, authorization, is a part of the operating system that protects computer resources by only allowing those resources to be used by resource consumers that have been granted authority to use them. Resources include individual files or items data, computer programs, computer devices and functionality provided by computer applications. Examples of consumers are computer users, computer programs and other devices on the computer. Authorization process makes use of the authentication process to identify consumers. When a consumer tries to use a resource, the authorization process checks that the consumer has been granted permission to use that resource. Permissions are generally defined by the computer's system administrator in some types of "security policy application", such as an access control list or a capability, on the basis of the "principle of least privilege": consumers should only be granted permissions they need to do their jobs. Older and single user operating systems often had weak or non-existent authentication and authorization systems. "Anonymous consumers" or "guests", are consumers that have not been required to authenticate. They often have very few permissions. On a distributed system, it is often desirable to grant access without requiring a unique identity. Familiar examples of authorization tokens include keys and tickets: they grant access without proving identity.

Recently among different ways of processing of materials the combined processing is applied. Applying different complex methods of processing of a surface of materials, it is possible to reduce a roughness of a processable surface, to increase thickness of a layer of the processed surface, to increase stability to wear process and microhardness. The further prospects in processing metals are opened with use of laser radiation and ultrasonic fluctuations. It is possible to notice, that complex ways of processing of metals are still not so widely investigated. This work is intended for research of a structure of steel in the field of influence of the combined laser radiation and ultrasonic fluctuations. It is established, that applying ultrasonic fluctuations at technologies of laser processing metals, it is possible to reach more uniform distribution of impurity in a surface of metal, to level a relief of the processed surface.
