Utveckling av kompatibilitetsdatabas

This report explains the need to develop a configuration manager that handles transmission equipment which exists in the Swedish Defence telecommunications network. The configuration module will display the configurations and compatibility among the equipment and their software which are all part of the network.Also included in this report are tools, methods and results for the development of a prototype for the configuration manager. The prototype consists fundamentally of a database assisted by a user friendly website.The transmission equipment handles a lot of important transmission of information and is in the hands of a department of SAAB, OFGCA, by orders from the Swedish Defence Materiel Administration (FMV). Within the work included in this order exists a continuous update of both software and hardware which the equipment consists of. Therefore it?s highly important that there is a monitoring of which of the software and hardware is compatible with one another, ensuring that the functions of the system work properly.The consistent updating has resulted in compatibility issues between components and because of this, a need for a configuration manager has arisen..

They need a suggestion for configuration for how the system and the application can work together. The work presented in this report is a suggestion for how you can make business configuration of an IT-based Treasury System in general. The exact configuration for the case received from If is presented as a separate report, found in Appendix A and is called the If-report. The If-report presents the suggested technical set-up of the configuration.

IDQ Viewer: För enklare Visning av Databasstruktur : Viewer : För enklare Visning av Databasstruktur

The social community is structured around data, a lot of that data is stored in different types of databases. The meaning of this essay is to develop an interactive tool that will change the way database visualization is done, and also to research in which fields a tool of this type can be used. With the help of different methods we discovered areas where it could be of use, such as; presentation of a database, development and documentation of a database. The primary goal of the prototype was to make viewing of database structures easier, even people without prior database knowledge should be able to understand the structure. During the development we used prototypes.

Säker grannupptäck i IPv6

The IPv6 protocol offers with some new functions, one of them is auto configuration. With auto configuration it is possible for nodes, i.e. hosts and routers, for automatically associated with IPv6 addresses without manual configuration. Auto configuration it is another protocol as it uses Neighbor Discovery protocol (ND) messages (ND is mandatory in the IPv6 stack). The main purpose of ND is that nodes can discover other nodes on the local link, perform address resolution, check that addresses are unique, and check the reachability with active nodes.There are exactly the same vulnerabilities of IPv6 as IPv4 and is now exception, ND if not properly secured.

Design och implementation av konfigurationsverktyg för funktionsblock

Abstract In high voltage substations there is an increasing demand for computerized equipment, and automation of operation and supervision. The future primary equipment will provide the possibility to collect more information and to provide better control for improved effectiveness. Since ABB has got a large customer target, each product must be custom made to fulfil the customers (often from different countries) demands. Later these products will be configured by engineers who may not be familiar with the tools used at ABB. This is a very expensive and time consuming.

Makten på Öland och i Möre : Järnålderns elit i ett lokalt perspektiv

The social elite on Öland and in Möre in the south east of Sweden during the Iron Age is described on the basis of the archaelogical record, such as graves, settlements and traces of pre-Christian central places. The material is discussed to see if traces of an elite are to be found. The power configuration between Öland and Möre is also discussed.

Praktiska effekter av begreppsförvirring för en databas konceptuella design : En fallstudie om databas- och begreppsmodellering

Company X develops a laboratory information system (LIS) called System Y. The informationsystem has a two-tier database architecture consisting of a production database and a historicaldatabase. A database constitutes the backbone of a IS, which makes the design of the databasevery important. A poorly designed database can cause major problems within an organization.The two databases in System Y are poorly modeled, particularly the historical database. Thecause of the poor modeling was unclear concepts.

Migration of a very large database with Swedish demographic data, using Microsoft SQL Server

SMC is in the process of developing a micro simulation model. The existing micro simulation model developed at Cornell University for US data, CorSim, is one of the fundamental parts for the new micro simulation at SMC. To develop the Swedish model, Swedish data on all individuals in Sweden during 11 years are also available. These data are organized in a database. This paper describes the process of rebuilding the database to a more useful structure.

Utveckling av internt Administrationssystem

This thesis work is executed at Business Unit Ericsson Test Environment (BETE), in Linköping. BETE is the department at Ericsson, which is responsible for the operation and maintenance of the company's Operations Support System (OSS). Their management system was outdated and they wanted it to be updated and it also required new features. The database needed to be replaced and the data migrated to a new database without licensing costs. The system also needed a part where employees could manage existing users.As a programming language PHP was chosen for its dynamic possibilities, platform independence and good support for database intergration.

Platt Hierarki : Metoder för omvandling av relationsdata till hierarkisk data

The relational database model was defined in the 1970?s and is the dominating database type today.  The main difference between data from a relational database and a hierarchical data structure is that the relational database stores records in tables. The records have no particular order, but can include links in terms of relationships with other records. A hierarchical structure organizes data in the form of a tree structure  and  can for an example be found in organizational structures in which different levels involves different responsibilities. If the data stored in a relational database is to be presented in a hierarchically, a conversion of the data structure is required. The intention of this paper is to describe how such a conversion can be performed.  To investigate the conversion methods, case studies has been conducted on the basis of a specific organization?s hierarchical structure.

Effektiv och underhållssäker lagring av medicinsk data

Creating a database to manage medical data is not the easiest. We create a database to be used for a presentation tool that presents medical data about patients that is stored in the database. We examine which of the three databases, MySQL with relational design, MySQL with EAV design and MongoDB that are best suited for storing medical data. The analysis i performed in two steps. The first step handles the database that is most effective to retriev data. The second step examines how easy it is to change the structure of the various databases. The results show that depending on whether efficiency or maintenance is most important, different databases are the best choise. MySQL with relational design proves to be most effective while MongoDB is the easiest to maintain..

Utveckling och design av WiGID

The Center for Genomics and Bioinformatics (CGB) is an academic department at Karolinska Institute. Generally stated, the CGB department is committed to the generation and management of genetic information by approaches aiming at elucidating the connection between genes, protein and function.WiGID is a genome information database that is available through WAP (Wireless Application Protocol).Our version of WiGID is based on WML, PHP and PostgreSQL as a database server.One of the changes on the old WiGID application was the creation of a relational database with seven tables and one view, instead of the file that represented the database on the old version. We also changed the script language from python to PHP.The search engine ability has been extended with three new search alternatives for a user to choose from. Each choice leads to other, sometimes multiple choices.A GUI has been created for the administrator, to be able to insert information into the database.The structure of the search engine is primarily for narrowing down the search result on the phone display, thereby making the search efficient..

Spetsbärförmåga hos betongpålar slagna i friktionsjord

The purpose of this study was to build a database for point-bearing piles in dense noncohesive soil, predominantly moraine. Further, the database was analysed and areas with difficult geotechnical conditions was identified.The database includes for point-bearing piles driven to refusal in moraine. Piles with mainly shaft friction have been excluded. Only concrete piles have been included. Geographically the database covers almost all geotechnical conditions of Sweden.

Kinematisk och dynamisk modellering av den haptiska enheten TAU i sex frihetsgrader

The thesis presents an optimally designed kinematic structure for a new 6-DOF haptic devicebased on TAU configuration. The configuration of the TAU-2 proposed by Suleman Khan andKjell Andersson [1] was modified and its mobility was verified by using Grübler criterion tohave a 6 DOF. Analytical kinematic models for the inverse and forward kinematics weredeveloped for the haptic TAU configuration to determine a set of optimal design parameters.Kinematic performance indices such as volume of the workspace, kinematic isotropy and payload index, were defined based on the singular values of the Jacobian matrix. The Jacobianmatrix was scaled to homogenize the physical units. The Jacobian matrix dependent on theposition and orientation of the end-effector gives local isotropy and pay load index, so globaldesign indices were defined, which represent the performance of the mechanism in the wholeworkspace.

Användning av realtidsdatabas i diagnostiksystem

The main purpose in this degree thesis is to investigate changes in performance when introducing a newly produced Real-Time database in one of CC Systems products, the Diagnostic Runtime Engine, DRE. The thesis is a collaboration between CC Systems, creator of DRE, and Mimer AB, developer of the Real-Time database.The result reveals that the time spent on database access is considerably lesscompared to the originally used database. The research has lead to several additional requirements on the real-time database and these are presented as part of the result in this thesis. The additional features will help making the product more suitable for DRE and similar applications.Additional research is required to be able to recommend the use of this product or not. Primarily the performance in another operating system, Windows CE, but also the introduction of additional features should be investigated.
