Colonial designs: Thomas Karsten and the planning of urban Indonesia

Thomas Karsten (1885 – 1945) is undoubtedly a major figure in the history of architecture and town planning in Indonesia. Between 1915 and 1941 he was involved in town planning in 12 of the 19 municipalities and towns in Java (the most prominent exception being Surabaya) 3 of the 9 towns in Sumatra, and the only town in Borneo This paper does not attempts to investigate or question his importance in this field but to place his architectural and town planning ideas in the context of his broader politico-cultural ideas and activities in the Dutch East Indies between 1914 and 1942, and these, in turn, in the context of an evolving colonialism and colonial discourse.

Development and applications of an experimental database for structural engineering education

A great number of research organisations in Japan have been conducting structural steel experiments for many years, particularly seismic tests of steel structures like cyclic-loading and pseudo-dynamic tests, in order to determine their seismic performances. However, the original test data gained by most research organisations are not well stored in an appropriate manner for distribution and possible usage by others. With the rapid development of information networks, structural engineers and researchers are able to exchange various types of test data through the Internet. In this paper, the authors present the development of a distributed collaborative database system for structural steel experiments. The database is made available on the Internet, and the use of Java language enables efficient interactive retrieval. The potential applications of the developed database system for structural engineering education are validated for the retrieval of experimental data and seismic numerical analysis.

Opportunities and challenges with J2SE 5 for introductory programming teaching

The recent release of the Java version 5.0 "Tiger" introduces some significant language changes. For educators, some of these changes provide opportunities to improve teaching, while others pose additional problems that require awareness to avoid them. The authors have recently completed the inclusion of support for all new language features into a wellknown educational IDE for Java – BlueJ – and in the course of doing so evaluated each of them for usefulness in education, and developed pedagogic strategies to handle the inherent opportunities and challenges. This has formed the basis of the design of the features in BlueJ which support the language changes. In this paper, we describe the results of our evaluation, provide recommendations on treatment of the new features in introductory courses and discuss how BlueJ may be used to illustrate important aspects.

Database for structural steel experiments under a distributed collaboration environment

Due to the high requirements of civil infrastructures against the earthquake in Japan, a great number of research organizations have been conducting the structural steel experiments, in particular the seismic tests such as the cyclic loading test and the pseudo-dynamic test, for many years to determine the seismic performances of steel structures. However, the original test data gained by most research organizations are not well stored in an appropriate manner for distribution and possible usage of others. Although a Numerical Database of Steel Structures (NDSS) was developed some years ago to preserve and share experimental data of the ultimate strength tests acquired at Nagoya University, it was not easy to access this database from other computer platform due to the lack of the support of proper communication media. With the rapid development of information networks and their browsers, structural engineers and researchers are able to exchange various types of test data through Internet. This paper presents the development of a distributed collaborative database system for structural steel experiments. The database is made available on the World-Wide Web, and the Java language enables the interactive retrieval efficiently. The applications of the developed database system for the retrieval of experimental data and seismic numerical analysis are validated in the form of examples.

Compositional connections : temple form in early Southeast Asia

The temples of Southeast Asia are remarkable and intriguing in their architecture, in that they are obviously derivative from Indic canon and yet
profoundly original and different from the corpus of the subcontinent. Further, the regional nuances of these temples, whether in Java, Cambodia or Champa, defy obvious and linear connections within these traditions and with the pan-Indic corpus. While epigraphists, Sanskritists and historians have made significant connections between these temple building traditions, much work remains to be done on the compositional and architectural linkages along the trading routes of South and Southeast Asia. This paper is an early attempt at understanding the compositional connections, as evident in the temple forms of early southeast Asia. To elucidate the complex material, the authors deploy a comparative method on two levels. Between ideal notions of the Hindu temple and shared cosmogony on one hand and individual temples as a realization of the ideal on the other. The consideration of the compositional material yields some surprisingly rich and varied connections. For example, the affinities between 7th century cellas in Cambodia and early Gupta models from central India are difficult to ignore. Further, the linkages between these cellas and the early Deccan experiments in structural stone raise questions about both idioms. The range of experimentation in Cambodia
(in plan forms, superstructure and construction methods are discussed with reference to their Indic antecedents. The findings of the paper raise questions about the relation between temple and treatise; between theory and practice and between the individual temple and its collective corpus.

Occurrence and distribution of established and new introduced bird species in north Sulawesi, Indonesia

Distributional and habitat information on eight introduced bird species in north Sulawesi, Indonesia, is presented. The accounts are based on our observations as well as being gathered from published sources and unpublished trip reports. Three species (Sulphur-crested Cockatoo Cacatua galerita, Sooty-headed Bulbul Pycnonotus aurigaster and Red-collared Dove Steptopelia tranquebarica) have not previously been reported in north Sulawesi in the published literature, while the continued presence and status of Java Sparrow Padda oryzivora, Zebra Dove Geopelia striata and Rock Dove Columba livia was considered uncertain in the published literature. Further work is required systematically to document the distribution, status and spread of introduced species in the north and other parts of Sulawesi—an imperative from both an economic and conservation perspective.

Simulation and visualization of fire using extended Lindenmayer systems

This research introduces a method of using Lindenmayer Systems to model the spreading and behavior of fire inside a factory building. The research investigates the use of L-System propagated fires for determining factors such as where the fire is most likely to spread first and how fast. It also looks at an alternative way of storing the Lindenmayer System, not in the form of a string but rather as a graph. A variation on the building and traversal process is also investigated, in which the L-System is traversed depth first instead of breadth first. Results of fire propagation are presented and we conclude that L-Systems are a suitable tool for fire propagation.

Trust ticket deployment : a notion of a data owner's trust in cloud computing

While cloud computing (CC) is a scalable model of shared infrastructure and on-demand computing, it lacks a transparent trust and security mechanism. A data owner (DO) loses control over the data outsourced to a machine in the cloud controlled and operated by a cloud service provider (CSP). This machine is at a location unknown to a data owner. This loss of control over data is further intensified with the lack of managing users' access to the data from practical cloud computing perspectives. In this paper, we introduce a new mechanism of ensuring trust and security in Software as a Service (SaaS) CC. Trust Ticket, with the supporting protocols, is our mechanism that helps a data owner in establishing a link between a CSP and a registered user. In our mechanism, a user first gets registered with a DO before receiving a Trust Ticket and a secret key from that DO. Each Trust Ticket is unique and encrypted. On completing the registration of each user, the DO apprises the CSP of the Trust Ticket. Trust Ticket and secret key are respectively for the registered user's getting accepted to the CSP and having a view of the data owner's data upon a successful verification by the CSP. We have done our experiment in Java network programming by creating an emulated cloud computing framework under the VMware ESXi 4.1 hyper visor based platform. Using the framework, we have evaluated our algorithmic protocol for Trust Ticket. We have also compared our work with prior work. Overall performance of our work is better. We argue that our proposed algorithmic protocol for Trust Ticket deployment establishes a data owner's trust. This trust is established through a data owner's control over data and a registered user, because a registered user is linked with a CSP by a data owner through Trust Ticket.

Early Connections : reflections on the canonical lineage of Southeast Asian temples

Temples were constructed across Southeast Asia following the spread of Brahmanic/Hindu culture between the fifth to eight centuries CE. Epigraphic evidence, architectural and stylistic similarities between temples in the region are strongly indicative of historic cross cultural links between the traditions. This paper presents the findings of a research project that pieces together fragments of evidence from early temple sites in Southeast Asia to establish the linkages between the Southeast Asian temple building traditions. The focus of the paper is on tracing the canonical connections between these traditions through an examination of temple sites in Cambodia and Java respectively. The legacy of this ancient diasporic movement remains celebrated today in the admiration of Southeast Asian monuments such as Angkor Wat and Prambanan. However this architecture evolved over time through a process of long experimentation with philosophies, world-views, and methods. . In order to permit a deeper examination of canonical connections, the authors use methods such as photogrammetry, digital and physical models to reconstruct the architectural forms. A detailed analysis of the canonical geometry and compositional form of these temples is undertaken with reference to Indic texts and temples. Comparing the relationships between cosmology, geometry and physical form in this earlier sites with both Indian and developed Southeast Asian models, it is intended that its generative role within Southeast Asian architectural historiography can be clarified and more fully celebrated.

Towards an understanding of the impact of advertising on data leaks

Recent investigations have determined that many Android applications in both official and non-official online markets expose details of the user's mobile phone without user consent. In this paper, for the first time in the research literature, we provide a full investigation of why such applications leak, how they leak and where the data is leaked to. In order to achieve this, we employ a combination of static and dynamic analysis based on examination of Java classes and application behaviour for a data set of 123 samples, all pre-determined as being free from malicious software. Despite the fact that anti-virus vendor software did not flag any of these samples as malware, approximately 10% of them are shown to leak data about the mobile phone to a third-party; applications from the official market appear to be just as susceptible to such leaks as applications from the non-official markets.

Facilitating learning by going online : modernising Islamic teaching and learning in Indonesia

This chapter examines the impact of eLearning and Web 2.0 social media in a socially conservative environment in Indonesia that has nevertheless proven surprisingly adroit at change management. Web 2.0 social media has proven enormously popular in Indonesia but traditional Islamic schools (which are known in Java as pesantren but elsewhere in the Muslim world as madrasah) the focus of this study is often unable to access Web 2.0 or the Internet in general. Progressive non-national government organizations (NGOs) seek to remedy this situation by providing satellite broadband links to remote schools and this chapter examines one particular project. Despite the impoverished and conservative nature of their community, the leaders of this school have led their students in a surprisingly enthusiastic reception of eLearning technology, recognizing its great capacity to produce and enhance social networks and provide new opportunities for learning. Particular attention in this case study is given to factors relating to social capital, attitudes, and patterns of behavior in leadership and change management. A case study approach was chosen to enable a richer and more finely-grained analysis of the issues. The case study is based on semi-structured interviews and observations conducted over several years. This research shows that whilst the adoption and uptake of eLearning with emerging technologies is strongly shaped by cultural and social factors, it plays out in very different ways than might first have been expected.

The constructional geometry of early Javanese temples

The early development of Hindu Javanese architecture can be traced through interpretation of epigraphs, archaeological excavations, and comparison of extant temples with other traditions. However, while many scholars have speculated on connections between Javanese Hindu temples and presumed antecedents in India, these have been made on the basis of visual comparison and epigraphic interpretations. No Indian temple has been conclusively shown to be a model for the earliest Javanese temples. Archaeologist and temple historian Michael Meister has shown in his analysis of the geometric composition of early Hindu temples in South Asia how a ritual sixty-four square mandala was the geometric basis of temple construction during the formative period (fifth to eighth century) of the Indian architectural tradition. Working from an understanding of temple construction sequence as well as their ritual underpinnings, Meister found that the sixtyfour square mandala's dimensions correlate closely to the constructed dimensions at the level of the vedibandha (which corresponds with the plan level of the sanctuary threshold). Furthermore, he shows how the horizontal profile of the cella depends on the number of offsets and the proportional relationships between ech offset based on the subdivision of the sixty-four square grid. The authors have investigated whether a similar compositional basis can be found for the earliest Javanese temples on the Dieng Plateau in the highlands of central Java, despite differences in architectonic and symbolic expression. The analysis of relationships between ritual geometry and actual temple layouts for these buildings has the potential to furthering our understanding of the connections between Hindu temples in Java and those in India.

Critical literacy in an Indonesian EFL setting: sustaining professional learning

 This study investigates factors leading to the successful design and implementation of critical literacy pedagogy in an English as a Foreign Language (EFL) class at a secondary school in the city of Bandung, West Java, Indonesia. Critical literacy pedagogy appears to have helped students to become more critical and socially aware.
