Kartdataimport för fälttillämpningRindberg, Jonas January 2006 (has links)
I dagsläget kan WM-datas Fältmodul i deras MoveITS-system inte hantera kartdata i andra format än Shape. Fältmodulen är en TabletPC som kör operativsystemet Windows XP. Den kan användas för att redigera viss geografisk information som exempelvis skyltpositioner. Fältmodulen används av Stockholms Tekniska kontor för inventering av skyltstolpar.Stockholms Tekniska kontor ska börja leverera sina kartor i GML (Geography Markup Language). Men eftersom WM-datas Fältmodul inte klarar av det formatet skulle det här examensarbetet gå ut på att ta fram komponenter för hantering av det. Då det under examensarbetets gång har varit svårt att få tag i information runt GML har istället en större fokus blivit lagd på MIF (MapInfo Interchange Format). Eftersom det finns andra kommuner som använder MIF finns det intresse från WM-data att det tas fram komponenter även för detta format.Ett stort antal klasser har utvecklats för hantering av MIF-filer. Dessa klasser är helt utvecklade i C# och har gjorts under examensarbetets gång utifrån de specifikationer som finns för formatet från företaget MapInfo. För GML har det tagits fram information som kan ligga till grund för utveckling av komponenter för hantering av det formatet.

GML Represntation for Interoperable Spatial Data Exchange in a Mobile Mapping ApplicationKanaparthy, Venu Madhav Singh 11 December 2004 (has links)
Geographic information is critical to GIS applications located remotely for executing business operations. GIS applications need to interoperate to be able to share information for analysis and decision making process. Heterogeneity and complexity of information models and structures limit the data flow and application interoperation. Advancements in Internet technologies provided new opportunities for delivering spatial information to remote users. However, spatial data delivered is in proprietary structures, limiting the utility to GIS applications. To enable information flow between GIS applications a portable data modeling approach is necessary. However, geographic information is inherently complex to model. A comprehensive and standardized vocabulary to model characteristics of geographic entities is required. Furthermore applications with the need to share information should have an agreement on information structure and content exchanged. This research presents GML representation to provide interoperable spatial data services. The objective is achieved by providing an open framework to model, encode and delivery geographic information. The results of this research show that it is possible to develop interoperable spatial data services through service oriented architecture.

Comparison of EMP and HERO programsBogan, Willie R. C. 12 1900 (has links)
Approved for public release; distribution is unlimited / Because of the unique features of electromagnetic pulse (EMP) and Hazardous
Electromagnetic Effects on Ordnance (HERO), much research and money has gone into
protecting weapon systems and ordnance against it. The EMP and HERO phenomena
do have a variety of differences and require differences of hardening technique to protect
against it. However, they both involve radiation effects and can prematurely initiate
ordnance via the electroexplosive device (EED). Protection of weapon systems and
ordnance against electronic damage and upset plus EED initiation takes on more of an
art form rather than science once basic principles are applied. Nevertheless by relating
these two programs via the initiating temperature of the EED. they can be accurately
compared with each other. Because of this observation, the two programs can be
effectively combined to work jointly on ordnance hardening and protection including all
forms of radiation type hazards, present and future. / http://archive.org/details/comparisonofemph00boga / Lieutenant. United States Navy

Aerothermodynamic analysis of a Coanda/Refraction jet engine test facilityMaraoui, André 12 1900 (has links)
Approved for public release; distribution is unlimited / A computer model of the Coanda Refraction Jet Engine Test Cell facility was developed
using the PHOENICS computer code. The PIIOENICS code was utilized to
determine the steady state aerothermal characteristics of the test cell during the testing
of an E404 gas turbine engine with afterburner in operation. Computer generated
aerothermodynamic field variables of pressure, velocity and temperature parameters
were compared to operational field test data. Observations regarding compared results
as well as system behavior are presented. Additionally, recommendations of the applications
of PHOENICS to future modeling projects are made. / http://archive.org/details/aerothermodynami00mara / Lieutenant, United States Navy

Modified GML Algorithm with Simulated Annealing for Estimation of Signal Arrival Time in WPAN SystemsChang, Lun-Kai 27 July 2006 (has links)
The main purpose of this thesis is to estimate the signal arrival time in low rate wireless personal area network systems. In a dense multipath environment, the generalized maximum-likelihood (GML) algorithm can be used for the time-of-arrival (TOA) estimation. Nevertheless, the GML algorithm is very time-consuming and usually takes a long period of time, and sometimes fails to converge. Hence, a simplified scheme that would improve the algorithm is investigated. In the simplified scheme, the search is executed in a sequential form. Two threshold parameters are determined for the stop condition in the algorithm. One threshold is on the arrival time of estimated path, while the other is on the fading amplitude of estimated path. The determination of thresholds can be based on the minimum error probability, which is defined as the sum of the false alarm probability and the missing probability. Root-mean-square error statistics are used to improve the thresholds setting. In this scheme, candidate pairs of thresholds are evaluated in each appropriate range. To solve the problem that the root-mean-square error value for each pair of thresholds is calculated, the simulated annealing is adopted for searching the best threshold pair. The problem that all possible solutions in a large range must be evaluated can be solved by simulated annealing. From the simulation results, it is seen that, while the signal-to-noise ratio is larger or equal to 4dB, the proposed scheme can achieve better performance than the root-mean-square error statistics scheme.

<p>In this thesis an approach to visualize internal behaviour of object oriented software is developed.</p><p>The runtime information, which can be described as objects calling other objects, is displayed as a graph consisting of nodes and edges.

Object Call Graph VisualizationTramnitzke, Danny January 2007 (has links)
In this thesis an approach to visualize internal behaviour of object oriented software is developed. The runtime information, which can be described as objects calling other objects, is displayed as a graph consisting of nodes and edges. The aim is to design an application in Java, which takes the runtime information in form of an object call graph and visualizes it as a tree and as a force directed view. Therefore, first a data model has to be designed, holding an object call sequence. Furthermore, a discussion about graph definition languages and according tools is made. After this different graph layout algorithms are examined as well as graph displaying tools. Finally, the implementation of this visualization program deals with the combination of these three components graph data extraction, graph layout calculation and graph visualization.
