Visualisierung dynamischer Raumphänomene in Geoinformationssystemen / Visualization of dynamic spatial phenomena in geographic information systems

Schmallowsky, Antje January 2009 (has links)
Die visuelle Kommunikation ist eine effiziente Methode, um dynamische Phänomene zu beschreiben. Informationsobjekte präzise wahrzunehmen, einen schnellen Zugriff auf strukturierte und relevante Informationen zu ermöglichen, erfordert konsistente und nach dem formalen Minimalprinzip konzipierte Analyse- und Darstellungsmethoden. Dynamische Raumphänomene in Geoinformationssystemen können durch den Mangel an konzeptionellen Optimierungsanpassungen aufgrund ihrer statischen Systemstruktur nur bedingt die Informationen von Raum und Zeit modellieren. Die Forschung in dieser Arbeit ist daher auf drei interdisziplinäre Ansätze fokussiert. Der erste Ansatz stellt eine echtzeitnahe Datenerfassung dar, die in Geodatenbanken zeitorientiert verwaltet wird. Der zweite Ansatz betrachtet Analyse- und Simulationsmethoden, die das dynamische Verhalten analysieren und prognostizieren. Der dritte Ansatz konzipiert Visualisierungsmethoden, die insbesondere dynamische Prozesse abbilden. Die Symbolisierung der Prozesse passt sich bedarfsweise in Abhängigkeit des Prozessverlaufes und der Interaktion zwischen Datenbanken und Simulationsmodellen den verschiedenen Entwicklungsphasen an. Dynamische Aspekte können so mit Hilfe bewährter Funktionen aus der GI-Science zeitnah mit modularen Werkzeugen entwickelt und visualisiert werden. Die Analyse-, Verschneidungs- und Datenverwaltungsfunktionen sollen hierbei als Nutzungs- und Auswertungspotential alternativ zu Methoden statischer Karten dienen. Bedeutend für die zeitliche Komponente ist das Verknüpfen neuer Technologien, z. B. die Simulation und Animation, basierend auf einer strukturierten Zeitdatenbank in Verbindung mit statistischen Verfahren. Methodisch werden Modellansätze und Visualisierungstechniken entwickelt, die auf den Bereich Verkehr transferiert werden. Verkehrsdynamische Phänomene, die nicht zusammenhängend und umfassend darstellbar sind, werden modular in einer serviceorientierten Architektur separiert, um sie in verschiedenen Ebenen räumlich und zeitlich visuell zu präsentieren. Entwicklungen der Vergangenheit und Prognosen der Zukunft werden über verschiedene Berechnungsmethoden modelliert und visuell analysiert. Die Verknüpfung einer Mikrosimulation (Abbildung einzelner Fahrzeuge) mit einer netzgesteuerten Makrosimulation (Abbildung eines gesamten Straßennetzes) ermöglicht eine maßstabsunabhängige Simulation und Visualisierung des Mobilitätsverhaltens ohne zeitaufwendige Bewertungsmodellberechnungen. Zukünftig wird die visuelle Analyse raum-zeitlicher Veränderungen für planerische Entscheidungen ein effizientes Mittel sein, um Informationen übergreifend verfügbar, klar strukturiert und zweckorientiert zur Verfügung zu stellen. Der Mehrwert durch visuelle Geoanalysen, die modular in einem System integriert sind, ist das flexible Auswerten von Messdaten nach zeitlichen und räumlichen Merkmalen. / Visual communication is an efficient method to describe dynamic phenomena. Perceiving information objects precisely and facilitating quick access to structured and relevant information requires consistent analysis and presentation methods conceived according to the formal minimisation principle. Because of the lack of conceptual optimisation adaptations due to their static system structure, dynamic space phenomena in geoinformation systems can only model the information of time and space conditionally. This is why research in this paper focuses on three interdisciplinary approaches. The first approach represents data collection close to real-time which is administered in geodatabases in a time-oriented manner. The second approach looks at analysis and simulation methods that analyse and forecast dynamic behaviour. The third approach conceives visualisation methods that model dynamic processes in particular. Where required, the symbolising of processes adapts to the various development phases depending on the process flow and the interaction between databases and simulation models. This allows dynamic aspects to be developed and visualised in a timely manner using modular tools with the help of proven geoscience functions. The analysis, intersection and data administration functions are intended to serve as utilisation and analysis potential as an alternative to static chart methods. For the time component, linking new technologies such as simulation and animation is significant based on a structured time database in connection with statistical methods. Modelling approaches and visualisation techniques are methodically developed and transferred to the traffic field. Dynamic traffic phenomena that cannot be modelled cohesively and comprehensively are separated into a service-oriented modular architecture in order to present them visually on different levels of space and time. Past developments and forecasts are modelled and visually analysed using various calculation methods. Linking a micro-simulation (modelling individual vehicles) to a network-controlled macro-simulation (modelling an entire road network) makes it possible to simulate and visualise mobility behaviour regardless of scale without time-consuming analysis model calculations. In the future, the visual analysis of space-time changes for planning decisions will be an efficient tool in order to make comprehensive, clearly structured and appropriate information available. The flexible analysis of measurement data according to time and space criteria represents the added value of visual geoanalysis integrated into a system with a modular structure.

Sistemas de comunicação CAN FD: modelamento por software e análise temporal. / CAN FD communication systems: modeling software and temporal analysis.

Andrade, Ricardo de 26 September 2014 (has links)
O CAN (Controller Area Network) é um padrão no barramento de comunicação, amplamente difundido em aplicações industriais, particularmente em sistemas automotivos. Atualmente, um dos principais problemas no ramo automotivo é que esse barramento está com muitas mensagens no barramento, resultado da incorporação incremental de sistemas eletrônicos em automóveis, visto que há uma exigência maior de conectividade devido às exigências da sociedade e mercado. Como alternativa, vem sendo desenvolvida uma nova rede de comunicação, conhecida como CAN with Flexible Data-Rate (CAN-FD), que é um barramento com velocidade de transmissão de informação mais alta e maior capacidade de transporte de dados. Este projeto tem por objetivo principal explorar as funcionalidades da rede CAN-FD, através de simulações do trânsito de mensagens numa rede CAN-FD usando os dados de uma rede real CAN, e verificando a previsibilidade de ambas no âmbito de um protocolo que possa atender à demanda de sistemas complexos. A comparação é executada a partir de um conjunto de mensagens adicionadas na rede, para verificar os limites de transmissão de cada uma das redes, e os respectivos tempos de atraso das mensagens. Como um segundo estudo de caso, uma rede de controle em malha fechada foi desenvolvida, conectada a um barramento CAN e um barramento CAN-FD. Essa técnica de controle permitiu eliminar os ruídos que interferem no controle, e checar o limite em que o protocolo de comunicação consegue manter em uma malha de controle funcionando. Os resultados mostraram que é possível transmitir uma imensa quantidade de dados com o menor uso do busload (quantidade de mensagens transmitidas) no veículo através do uso do barramento CAN-FD, porém ainda não foi lançado no mercado um controlador do CAN-FD para realizar essa tarefa. Por outro lado, os dois protocolos, CAN-FD e CAN, tem suas previsibilidades comprometidas pois não conseguem enviar a mensagem quando o barramento está superior a 98,86% de carga. / The CAN (Controller Area Network) is a standard in the communication bus, widespread in industrial applications, particularly in automotive systems. Currently, one of the main problems in the automotive industry is that this bus is with many messages on the bus, the result of incremental incorporation of electronic systems in automobiles, since there is a greater demand for connectivity due to the demands of society and the market. Alternatively, it has been developed a new communications network, known as CAN with Flexible Data-Rate (CAN-FD), which is a bus with transmission speeds higher and higher capacity data transport information. This project\'s main objective is to explore the features of the network CAN-FD, through simulations of the traffic of messages on a CAN network FD using data from a real CAN network, and verifying the predictability both in the context of a protocol that can meet the demand complex systems. The comparison is performed from a set of messages added to the network to verify the boundaries of each of the transmission networks and the respective delay times of the messages. As a second case study, a network of closed-loop control was developed, connected to a CAN bus and CAN bus FD. This control technique has eliminated the noises that interfere with the control and check the extent that the communication protocol can keep a control loop running. The results showed that it is possible to transmit a huge amount of data with the lowest usage busload (amount of transmitted messages) to the vehicle through the use of CAN bus FD, but not yet released to market a CAN controller FD to accomplish this task . Moreover, both protocols, CAN-FD and CAN has its predictability compromised because they are unable to send the message when the bus is more than 98.86% load.

Analysing the use of integrated marketing communication at the View Boutiqu Hotel in Johannesburg, South Africa

Mebuge, Chinelo Ogochukwu 07 1900 (has links)
Text in both English and Afrikaans / Since the early 2000s, the tourism industry in South Africa has experienced phenomenal change and, concomitantly, the hospitality industry has also seen significant growth. This growth has been driven by factors such as the increased demand for hospitality in both the leisure and the business markets. The hotel industry has immensely been benefited. The Tourism Business Index’s report released quarterly by the Tourism Business Council of South Africa, indicating that the revenue received from each available room in the hotel sector increased significantly from 2009. Tourism research has revealed that, globally, the hospitality industry is among the largest employers of labour. The hospitality industry, especially the hotel sector, works hand in hand with tourism. Tourists traveling to a destination require accommodation which is generally provided by hotels. If the tourist is to have a good experience, it is vital that the tourist organisation and the hotel communicate so as to exchange information. Integrated marketing communication (IMC) has been described as a concept that many organisations adopt in order both to coordinate the operation of the organisation effectively and to increase the bottom line. In IMC, also creates synergy within an organisation and paves the way for consistent messages to be sent out to the organisation’s target audience. The aim of this study was to analyse the use of IMC by the View Boutique Hotel in Johannesburg, South Africa. To analyse the IMC at the hotel, in-depth interviews were conducted with both marketing staff and guests. In the aspect of planned messages, the outcome of the study revealed that the hotel uses marketing communication tools on a limited scale and, that to ensure message consistency the manager handles all external communication activities. However, the study also showed that ensuring message consistency should be the responsibility of everyone employed in the hotel. With regard to the product messages, the study showed that guests were negatively disposed towards the food, beverages, entertainment and recreation offered by the hotel. However, the service messages of the study indicated that the hotel’s service quality was good and that the staff were responsive to the needs of the guests. In respect of unplanned messages, the study showed that the hotel was receiving limited coverage from the media and that word of mouth communication was an effective tool in the hotel’s communication toolbox. On the whole, thus, it may be said that the study underscores the centrality of IMC as an instrument for creating and nurturing the relations between the hotel and its quests. It is anticipated that the outcome of this study should provide hotels such as the View Boutique Hotel with guidance in regard to utilising IMC to its full potential to make sure that there is message consistency and also to optimise communication impact. / Sedert die vroeë 2000's het die toerismebedryf in Suid-Afrika 'n merkwaardige verandering ondergaan, en daarmee saam het die gasvryheidsbedryf aansienlike groei getoon. Hierdie groei is aangevuur deur faktore soos die toenemende vraag na gasvryheid in die ontspannings- en sakemark. Die hotelbedryf het baie hierby gebaat. Volgens die besigheidsindeks vir toerisme wat kwartaalliks deur die Toerismebesigheidsraad van Suid-Afrika vrygestel word, het die inkomste uit elke beskikbare kamer in die hotelbedryf sedert 2009 aansienlik toegeneem. Navorsing oor toerisme het getoon dat die gasvryheidsbedryf wêreldwyd die meeste werk verskaf. Die gasvryheidsbedryf, en veral die hotelbedryf, gaan hand aan hand met toerisme. Toeriste wat na 'n bestemming reis het akkommodasie nodig wat oor die algemeen deur hotelle gebied word. Om te verseker dat toeriste positiewe belewenisse het, is dit kritiek dat toeriste-organisasies en hotelle kommunikeer om inligting uit te ruil. Geïntegreerde bemarkingskommunikasie word beskryf as 'n konsep wat baie organisasies aanneem om die bedryf van die organisasie effektief te koördineer en die netto wins te verhoog. Geïntegreerde bemarkingskommunikasie skep medewerking in 'n organisasie en baan die weg vir konsekwente boodskappe wat aan die organisasie se teikengehoor uitgedra word. Die doel van hierdie studie was om die gebruik van geïntegreerde bemarkingskommunikasie by die View Boutique Hotel in Johannesburg, Suid-Afrika, te ondersoek. In die ondersoek van die geïntegreerde bemarkingskommunikasie by die hotel is diepgaande onderhoude met bemarkingspersoneel en gaste gevoer. Ten opsigte van beplande kommunikasie het die studie bevind dat die hotel bemarkingskommunikasie-instrumente op beperkte skaal gebruik, en om te verseker dat die kommunikasie konsekwent is, hanteer die bestuurder alle eksterne kommunikasie-aktiwiteite. Die studie het egter ook getoon dat dit elke werknemer by die hotel se verantwoordelikheid is om konsekwente kommunikasie te verseker. Met verwysing na produkkommunikasie het die studie getoon dat die gaste negatief ingestel was oor die kos, drankies, vermaaklikheid en ontspanning wat by die hotel aangebied is. Die studie het egter bevind dat die diens by die hotel goed was en dat die personeel goed op die gaste se behoeftes gereageer het. Met betrekking tot ix onbeplande kommunikasie het die studie getoon dat die hotel beperkte dekking in die media geniet en dat mondelinge kommunikasie 'n doeltreffende instrument in die hotel se arsenaal is. Oor die algemeen kan daar gesê word dat die studie die sentraliteit van geïntegreerde bemarkingskommunikasie onderskryf as instrument vir die skep en uitbou van verhoudings tussen die hotel en sy gaste. Die resultate van hierdie studie behoort aan hotelle soos die View Boutique Hotel riglyne te bied oor hoe geïntegreerde bemarkingskommunikasie ten volle benut kan word om konsekwente kommunikasie te verseker, en om die impak van kommunikasie te optimeer. / Communication Science / M.A.(Psychology)

Automatické generování testovacích dat informačních systémů / Automatic Test Input Generation for Information Systems

Naňo, Andrej January 2021 (has links)
ISAGENis a tool for the automatic generation of structurally complex test inputs that imitate real communication in the context of modern information systems . Complex, typically tree-structured data currently represents the standard means of transmitting information between nodes in distributed information systems. Automatic generator ISAGENis founded on the methodology of data-driven testing and uses concrete data from the production environment as the primary characteristic and specification that guides the generation of new similar data for test cases satisfying given combinatorial adequacy criteria. The main contribution of this thesis is a comprehensive proposal of automated data generation techniques together with an implementation, which demonstrates their usage. The created solution enables testers to create more relevant testing data, representing production-like communication in information systems.
