This Master's thesis was written to create the extension for an experimental rendering engine CSSBox about scripting support in JavaScript language. In the theoretical section the thesis describes the architecture of the rendering engine and introduces problems of the scripting in HTML documents according to the recommended HTML 5 specification. This thesis deals with thorough analysis of existing scripting engines and their interfaces, which could be used for the extension implementation. Depending on the knowledge gained from the previous parts this thesis focuses only on the scripting engine Rhino and introduces an abstract design of its integration into the CSSBox project. At the end it evaluates the reliability and efficiency of the implemented functionalities and considers possibilities of their further development.

The content of this thesis is devided into five parts. Firstly basic principles, data models and some languages of temporal databases are introduced. Next chapter describes ways and techniques for persistent storing of data objects in the programming language Java. Following chapters contain main ideas and key concepts of the Java Data Objects standard, draft for temporal extension of this standard and in the final chapter there are details of the actual implementation.

This thesis explores the execution of object-oriented code on an embedded Java platform. It presents established and derives new approaches for the implementation of high-level object-oriented functionality and commonly expected system services. The goal of the developed techniques is the provision of the architectural base for an efficient and predictable code execution. The research vehicle of this thesis is the Java-programmed SHAP platform. It consists of its platform tool chain and the highly-customizable SHAP bytecode processor. SHAP offers a fully operational embedded CLDC environment, in which the proposed techniques have been implemented, verified, and evaluated. Two strands are followed to achieve the goal of this thesis. First of all, the sequential execution of bytecode is optimized through a joint effort of an optimizing offline linker and an on-chip application loader. Additionally, SHAP pioneers a reference coloring mechanism, which enables a constant-time interface method dispatch that need not be backed a large sparse dispatch table. Secondly, this thesis explores the implementation of essential system services within designated concurrent hardware modules. This effort is necessary to decouple the computational progress of the user application from the interference induced by time-sharing software implementations of these services. The concrete contributions comprise a spill-free, on-chip stack; a predictable method cache; and a concurrent garbage collection. Each approached means is described and evaluated after the relevant state of the art has been reviewed. This review is not limited to preceding small embedded approaches but also includes techniques that have proven successful on larger-scale platforms. The other way around, the chances that these platforms may benefit from the techniques developed for SHAP are discussed.

GlobalEye is an aircraft by Saab that provides surveillance of air, sea, and land. In order to train on the system present in this aircraft a Mission Training System, MTS, is used. The MTS consists of the Command and Control, C2, system that is present in the aircraft as well as a scenario simulator. This master thesis is focused on evaluating the performance of the distributed real-time system that is the MTS in terms CPU and memory usage of its Java processes. These Java processes are divided across four servers and two types of workstations.  Two sorts of tests were conducted; workload model testing and user scenario testing. Both tests were conducted multiple times with different amount of workload. The workload was defined as a number of air and sea targets added to the scenario simulator. The data was collected by running bash scripts on each machine that saved the CPU and memory output from the Linux top command. Java VisualVM was used to examine a selection of processes further. In Java VisualVM the heap size, garbage collector pauses, and CPU time of the methods were the main focus of interest. The result from the workload model testing showed that a large majority of the processes handled an increased workload in terms of memory usage well. When it comes to the CPU usage four processes with significantly increasing CPU values were examined further in Java VisualVM. These processes were MMI processes and processes involved in data transfer. No problems were noted regarding the garbage collection and heap sizes. The longest pause, across all processes, caused by garbage collection was 29.7ms. The methods with highest amount of CPU self time were also identified for the processes. One observation was that a method related to map rendering, for the MMI processes, showed decreases in CPU time as the workload increased. The result from the user scenario testing showed that the MMI of the scenario simulator suffers delays dependant on the number of targets present in the scenario. The Java process of the MMI did increase its CPU usage significantly as the targets increased. In Java VisualVM it was observed that the garbage collector for the scenario simulator MMI process was more extensive during these tests, with the longest pause being 104ms. Lastly when it comes to the CPU self time of the methods within the MMI process, one error related method was identified.

ITC/USA 2007 Conference Proceedings / The Forty-Third Annual International Telemetering Conference and Technical Exhibition / October 22-25, 2007 / Riviera Hotel & Convention Center, Las Vegas, Nevada / Increasingly, many software developers are facing the challenge of adapting software applications developed on one platform to work on multiple platforms. While software standards have helped this effort, they do not go far enough, and many platforms only partially support these standards leaving many needed functions in platform specific libraries. This is particularly evident in the areas of graphics and user interfaces, threading and synchronization, and in network and file access. Fortunately, Java offers a common interface where native libraries diverge. This paper outlines a phased strategy for migrating platform specific applications to be platform independent while reusing the robust, existing algorithms.

Yogyakarta and Surakarta are two cities on the island of Java, Indonesia, which are considered as the centres of Javanese culture. That identity has resulted from the existence of the royal court or kraton in each of them. Both cities have shared a similar history as descendants of the Mataram kingdom, the greatest kingdom in Java, which was divided into two in 1755. Both also share a similar physical layout of the palace, shown not only in the layout of the kraton compounds, which consist of seven hierarchical courtyards, but also in the names and the functions of the courtyards and buildings. They also share similar city layouts in which the palace located at the centre, two squares each at the northern and southern end of the kraton compounds, and a royal road, create a north-south axis which is claimed to be cosmological. However, the kratons have suffered different fates in the modern era. Since Indonesian Independence in 1945, Yogyakarta has been considered to be a ‘special region’, with its territory awarded a status equivalent to a province. Also the king is automatically appointed governor, while Surakarta is only recognised as a city, which is a part of the province of Central Java. While the kraton of Yogyakarta holds importance in Yogyakarta, with the acknowledgement of territory and the king’s political role as governor, the kraton of Surakarta has no influence in the city of Surakarta. The mayor of Surakarta city is elected by the people, and even in the 2010 election a candidate from the royal family of the kraton of Surakarta lost 10:90 to a non-kraton-related candidate. The kraton of Yogyakarta has its land and property acknowledged by the state, while the kraton of Surakarta has its land and properties appropriated by the state, except the palace and some of its noble houses. The description above shows that there is a difference in power levels between both kratons. This thesis examines the background process of power, particularly those related to architecture and the built environment including arts, rituals, and culture integrated with them. Based on Bourdieu’s theory of structure/agency, I focused myself on the silent ideology of the built environment, which embodies a power structure in people’s unconsciousness through experience, in order to find out why differences in power levels occurred in two places that share a similar history and physical layouts. Using a comparative analysis, I examine in detail the silent ideology in terms of landscape, in both urban and architectural context. This silent ideology, with the support of cosmological narratives and colonial discourses, together with the accumulation of history in each of them, has a determining role in reproducing the existing power structure and continuous effort as this silent ideology helps to make sure that the existing power structures last.

International Telemetering Conference Proceedings / October 21, 2002 / Town & Country Hotel and Conference Center, San Diego, California / Because of an ever-increasing need for performance and high predictability in modern real-time telemetry systems, the Java programming language is typically not considered a viable option for embedded software development. Nevertheless, the Java platform provides many features that can easily be applied to embedded telemetry systems that other development platforms cannot match. But obviously, there are pitfalls to be aware of. This paper will present an alternative solution to address today’s problems in real-time telemetry systems and will cover the following topics: • Java development platforms for the embedded world • Impact on software portability and reusability • Performance and optimization techniques • Direct access to hardware devices • Memory management and garbage collection • Network-centric component-oriented architecture • Real-time examples from past experience • Future developments

International Telemetering Conference Proceedings / October 23-26, 2000 / Town & Country Hotel and Conference Center, San Diego, California / The Range Instrumentation and Control System (RICS) is the twenty-first century replacement for an aging time-space-position information (TSPI) distribution and collection system used by the 46th Test Wing at Eglin AFB, Florida. The purpose of the RICS is to collect TSPI and distribute it across a wide area network in real-time. It will utilize a multi-threaded C++ program on VxWorks (a real-time operating system by Wind River Systems) to acquire TSPI from a radar system. The acquired data will be multicast to several local area networks where the data will be recorded and displayed in real-time using a Java program on the Linux operating system. This paper describes the design process and design rationale for developing a distributed, real-time, heterogeneous system.
