Semi-automatic semantic enrichment of raw sensor data

One of the more recent sources of large volumes of generated data is sensor devices, where dedicated sensing equipment is used to monitor events and happenings in a wide range of domains, including monitoring human biometrics. In recent trials to examine the effects that key moments in movies have on the human body, we fitted fitted with a number of biometric sensor devices and monitored them as they watched a range of dierent movies in groups. The purpose of these experiments was to examine the correlation between humans' highlights in movies as observed from biometric sensors, and highlights in the same movies as identified by our automatic movie analysis techniques. However,the problem with this type of experiment is that both the analysis of the video stream and the sensor data readings are not directly usable in their raw form because of the sheer volume of low-level data values generated both from the sensors and from the movie analysis. This work describes the semi-automated enrichment of both video analysis and sensor data and the mechanism used to query the data in both centralised environments, and in a peer-to-peer architecture when the number of sensor devices grows to large numbers. We present and validate a scalable means of semi-automating the semantic enrichment of sensor data, thereby providing a means of large-scale sensor management

Mapping and Displaying Structural Transformations between XML and PDF

Documents are often marked up in XML-based tagsets to delineate major structural components such as headings, paragraphs, figure captions and so on, without much regard to their eventual displayed appearance. And yet these same abstract documents, after many transformations and 'typesetting' processes, often emerge in the popular format of Adobe PDF, either for dissemination or archiving. Until recently PDF has been a totally display-based document representation, relying on the underlying PostScript semantics of PDF. Early versions of PDF had no mechanism for retaining any form of abstract document structure but recent releases have now introduced an internal structure tree to create the so called 'Tagged PDF'. This paper describes the development of a plugin for Adobe Acrobat which creates a two-window display. In one window is shown an XML document original and in the other its Tagged PDF counterpart is seen, with an internal structure tree that, in some sense, matches the one seen in XML. If a component is highlighted in either window then the corresponding structured item, with any attendant text, is also highlighted in the other window. Important applications of correctly Tagged PDF include making PDF documents reflow intelligently on small screen devices and enabling them to be read out in correct reading order, via speech synthesiser software, for the visually impaired. By tracing structure transformation from source document to destination one can implement the repair of damaged PDF structure or the adaptation of an existing structure tree to an incrementally updated document

The Design of XML-Based Model and Experiment Description Languages for Network Simulation

The Simulation Automation Framework for Experiments (SAFE) is a project created to raise the level of abstraction in network simulation tools and thereby address issues that undermine credibility. SAFE incorporates best practices in network simulationto automate the experimental process and to guide users in the development of sound scientific studies using the popular ns-3 network simulator. My contributions to the SAFE project: the design of two XML-based languages called NEDL (ns-3 Experiment Description Language) and NSTL (ns-3 Script Templating Language), which facilitate the description of experiments and network simulationmodels, respectively. The languages provide a foundation for the construction of better interfaces between the user and the ns-3 simulator. They also provide input to a mechanism which automates the execution of network simulation experiments. Additionally,this thesis demonstrates that one can develop tools to generate ns-3 scripts in Python or C++ automatically from NSTL model descriptions

Generic Web Server in Embedded Control Systems

The goal for this master thesis was to investigate the possibility of using an existing web server and modify it so it can be used in ABB controllers. The work has resulted in two different versions of a web server. The basic functionality is the same for both versions. The web servers are able to present a number of controller-related information. For example: hardware, which control programs that are executing in the controller, information about the firmware, and also system information like heap memory usage. It can also be used for changing different parameters. The two versions use different techniques for presenting the information. They are also implemented in different ways. The first version has a more user-friendly interface but requires more memory, 71 kb. The second version requires less memory, 48 kb, but does not have the same user-friendly interface

BSML: A Binding Schema Markup Language for Data Interchange in Problem Solving Environments (PSEs)

We describe a binding schema markup language (BSML) for describing data interchange between scientific codes. Such a facility is an important constituent of scientific problem solving environments (PSEs). BSML is designed to integrate with a PSE or application composition system that views model specification and execution as a problem of managing semistructured data. The data interchange problem is addressed by three techniques for processing semistructured data: validation, binding, and conversion. We present BSML and describe its application to a PSE for wireless communications system design

Integration of relational database metadata and XML technology to develop an abstract framework to generate automatic and dynamic web entry forms.

Developing interactive web application systems requires a large amount of effort on designing database, system logic and user interface. These tasks are expensive and error-prone. Web application systems are accessed and used by many different sets of people with different backgrounds and numerous demands. Meeting these demands requires frequent updating for Web application systems which results in a very high cost process. Thus, many attempts have been made to automate, to some degree, the construction of Web user interfaces. Three main directions have been cited for this purpose. The first direction suggested of generating user interfaces from the application¿s data model. This path was able to generate the static layout of user interfaces with dynamic behaviour specified programmatically. The second tendency suggested deployment of the domain model to generate both, the layout of a user interface and its dynamic behaviour. Web applications built based on this approach are most useful for domain-specific interfaces with a relatively fixed user dialogue. The last direction adopted the notion of deploying database metadata to developing dynamic user interfaces. Although the notion was quite valuable, its deployment did not present a generic solution for generating a variety of types of dynamic Web user interface targeting several platforms and electronic devices. This thesis has inherited the latter direction and presented significant improvements on the current deployment of this tendency. This thesis aims to contribute towards the development of an abstract framework to generate abstract and dynamic Web user interfaces not targeted to any particular domain or platform. To achieve this target, the thesis proposed and evaluates a general notion for implementing a prototype system that uses an internal model (i.e. database metadata) in conjunction with XML technology. Database metadata is richer than any external model and provides the information needed to build dynamic user interfaces. In addition, XML technology became the mainstream of presenting and storing data in an abstract structure. It is widely adopted in Web development society because of its ability to be transformed into many different formats with a little bit of effort. This thesis finds that only Java can provide us with a generalised database metadata based framework. Other programming languages apply some restrictions on accessing and extracting database metadata from numerous database management systems. Consequently, JavaServlets and relational database were used to implement the proposed framework. In addition, Java Data Base Connectivity was used to bridge the two mentioned technologies. The implementation of our proposed approach shows that it is possible and very straightforward to produce different automatic and dynamic Web entry forms that not targeted at any platform. In addition, this approach can be applied to a particular domain without affecting the main notion or framework architecture. The implemented approach demonstrates a number of advantages over the other approaches based on external or internal models

A lightweight XML-based middleware architecture

Predefined components often require adaption to make them work together including an adaption of the data exchanged. The present paper describes an XML based approach to solve the adoption of data. It includes the serialization of objets to XML, the transformation with XSLT, and the parsing and construction of the transformed objects. The pre-agreed document types involved allow a pre-compilation of the processes. Compared to standard interpreted XML processing, this approach reduces the online adaptation processes and speeds up the components\u27 communication

XSLT Benchmarking

Hlavním cílem této práce bylo vytvoření XSLT Benchmarku, tedy srovnání dostupných XSLT procesorů. Nejprve jsme si stanovili hlavní kritéria XSLT procesorů (cena, korektnost, rychlost, využití paměti, podpora, OS a UX), která budeme diskutovat. Poté jsme shrnuli existující XSLT procesory, popsali jednotlivé typy procesorů (program, knihovna a prohlížeč) a ohodnotili kritéria cena, podpora, OS a UX. Abychom mohli ohodnotit kritéria korektnost, rychlost a využití paměti, museli jsme si vytvořit vhodné testovací prostředí. Vytvořený program XSLT Benchmarking je jedním z hlavních přínosů této práce. Součástí programu jsou také připravené testy. Při jejich vytváření, jsme vycházeli z 5787 stažených XSLT souborů. Testy byly vytvořeny na základě analýzy těchto souborů. Zaprvé jsme zkoumali obecné vlastnosti XSLT souborů (použité elementy, použité XSLT verze, formát výstupu atd.). Zadruhé jsme zkoumali zaměření jejich použití. Dalším velkým přínosem této práce je shrnutí výsledků testů z různých pohledů. V tomto shrnutí jsme okomentovali další kritéria a vlastnosti testovaných procesorů. Na závěr jsme shrnuli možná rozšíření našeho programu i naší analýzy.The main goal of this work was to create an XSLT Benchmark, to compare available XSLT processors. At first, we determined main criteria of XSLT processors (price, correctness, speed, memory usage, support, OS and UX), which we discussed. Next, we summarized existing XSLT processors, described individual types of processors (program, library and browser) and measured criteria price, support, OS} and UX. We had to create appropriate test environment to measure criteria correctness, speed and memory usage. Created program XSLT Benchmarking is one of the main benefits of this work. The program also includes tests. We created tests based on 5787 downloaded XSLT files. Tests were created based on the analysis of these files. Firstly, we researched common features of XSLT files (used elements, used XSLT versions, output format etc.). Secondly, we researched focuses of their usages. Next big benefit of this work is a summary of results of tests from different views. We discussed other criteria and features of tested processors. Finally, we summarized possible extensions of our program and also of our analysis.Department of Software EngineeringKatedra softwarového inženýrstvíFaculty of Mathematics and PhysicsMatematicko-fyzikální fakult
