Reconfigurable computing architectures allow the adaptation of the underlying datapath to the algorithm. The granularity of the datapath elements and data width determines the granularity of the architecture and its programming flexibility. Coarse-grained architectures have shown the right balance between programmability and performance. This paper provides an overview of coarse-grained reconfigurable architectures and describes Versat, a Coarse-Grained Reconfigurable Array (CGRA) with self-generated partial reconfiguration, presented as a case study for better understanding these architectures. Unlike most of the existing approaches, which mainly use pre-compiled configurations, a Versat program can generate and apply myriads of on-the-fly configurations. Partial reconfiguration plays a central role in this approach, as it speeds up the generation of incrementally different configurations. The reconfigurable array has a complete graph topology, which yields unprecedented programmability, including assembly programming. Besides being useful for optimising programs, assembly programming is invaluable for working around post-silicon hardware, software, or compiler issues. Results on core area, frequency, power, and performance running different codes are presented and compared to other implementations.

Reconfigurable Hardware Architecture

Since the introduction of the first reconfigurable devices in 1985 the field of reconfigurable computing developed a broad variety of architectures from fine-grained to coarse-grained types. However, the main disadvantages of the reconfigurable approaches, the costs in area, and power consumption, are still present. This contribution presents a solution for application-driven adaptation of our reconfigurable architecture at register transfer level (RTL) to reduce the resource requirements and power consumption while keeping the flexibility and performance for a predefined set of applications. Furthermore, implemented runtime adaptive features like online routing and configuration sequencing will be presented and discussed. A presentation of the prototype chip of this architecture designed in 90 nm standard cell technology manufactured by TSMC will conclude this contribution.

This article investigates ways in which theatre and performance have the potential to revisit and re-interpret ideological narratives. Drawing on the politics of transnational performance-making processes, it examines how multilingual theatre productions can contribute to the production of subjective and collective identities, and help articulate ideas and perceptions of belonging. With reference to 20/20 – a piece of documentary-style theatre about a major inter-ethnic conflict that took place in 1990 in a bilingual city in Romania – this case study maps out arguments for utilizing multilingualism on stage, and engages with the ethics of representation in the process of multilingual transfer. Billed as  ‘multi-ethnic and multilingual’, the production embraces an agenda that goes beyond the examination of an isolated local conflict and makes the point that both theatre-making and theatre-going are experiences that strongly interact with narratives of cultural identity and hybridization. Thus, the representation of belonging or not belonging is tied in with questions of agency, and the right of individuals to affirm and indeed interrogate their hereditary links to a community.

Electricity demand forecasting has attracted the attention of many researchers and power company staff. It still does so because with better forecasting, power companies can approach exact plans with no over- or –under planning. This is reflected as being the right investment in terms of time, money, and performance. In essence a good demand forecast means the right investment plan and therefore, satisfied customers. In reality this is the objective of any business; to be able to estimate the demand as close to reality as possible. The number and extent of demand forecasting methodologies and models developed is tremendous, however, there exists no novel technique that can serve all situations. Basically forecasting models can be divided into statistically based and intelligence-based models. A description of forecasting models helps in identifying the characteristics, features, and strengths of each model. The selection of the most suitable forecasting algorithm is not an easy process. The time frame of the forecast, data availability, the accuracy and cost of the forecast, the application and purpose of the forecast are some of the important parameters in the selection process. A case study of two forecasting models used in Jordan is presented. The discussion of the case study shows that load forecasting in Jordan is based on an intelligence-based model for short term forecasting, and on a combination of traditional statistically-based models for long term forecasting.

The benefits of automatic identification technologies in healthcare have been largely recognized. Nevertheless, unlocking their potential to support the most knowledge-intensive medical tasks requires to go beyond mere item identification. This paper presents an innovative Decision Support System (DSS), based on a semantic enhancement of Near Field Communication (NFC) standard. Annotated descriptions of medications and patient’s case history are stored in NFC transponders and used to help caregivers providing the right therapy. The proposed framework includes a lightweight reasoning engine to infer possible incompatibilities in treatment, suggesting substitute therapies. A working prototype is presented in a rheumatology case study and preliminary performance tests are reported. The approach is independent from back-end infrastructures. The proposed DSS framework is validated in a limited but realistic case study, and performance evaluation of the prototype supports its practical feasibility. Automated reasoning on knowledge fragments extracted via NFC enables effective decision support not only in hospital centers, but also in pervasive IoT-based healthcare contexts such as first aid, ambulance transport, rehabilitation facilities and home care.

ABSTRACT This research will elaborate four Indonesian contemporary choreographers, which lead to open the significant of embodiment process on Indonesian dancers. With a focus on four choreographers, Mar- tinus Miroto, Mugiyono Kasido, Hartati, and Jecko Siompo. A case study of body of those four choreo- graphers has reached its “institutional” level, so choosing those four characters, as a representation of Indonesian dancer is the right thing to do. With the complexity discipline and body work training, the four dancers and choreographer strengthening on how procession to achieve and advancing body work is located in some important process: exercise, training, and performance. This is different from the pro- cess of body works quality and the achievement of most dancers and choreographer outside of Indonesia. Usually the dancers outside of Indonesia only stress on two things: Training and performance. The four dancers in the work have had a typical body works each of them, but it is undeniable that there is a role in the respective Sardono as the maestro. Sardono’s strong influence thus again took place in forming a model to the body or body-dance attitude of dancers who then the outcome was, in fact, different from Sardono’s works. Keywords: contemporary, embodied, training, rehearsal, performance  ABSTRAK Penelitian ini membahas empat koreografer, dalam membuka wacana proses ketubuhan penari di Indonesia. Empat koreografer tersebut, Martinus Miroto, Mugiyono Kasido, Hartati, dan Jecko Siompo, memperlihatkan betapa kompleksitas proses ketubuhan mereka berbeda dengan penari dan koreografer pada umumnya, terutama dari luar Indonesia. Mereka mem- berikan pengalaman yang detail tentang pendisiplinan tubuh mereka untuk mencapai sebuah capaian dan keunggulan. Dengan kompleksitas disiplin dan training ketubuhan, keempat penari dan koreografer ini menggukuhkan betapa proses pencapaian dan kemuktahiran tubuh terletak pada beberapa proses penting: Training, Latihan, dan Pementasan. Jika ditilik secara ke- seluruhan, keempat penari ini mempunyai pengalaman belajar, atau setidaknya pernah men- galami proses menari bersama Sardono W. Kusumo. Ketubuhan yang yang dieksplorasi adalah ciri khas dari Sardono yang dikenal dengan laku dalam bahasa Jawa. Walaupun belajar dari Sar- dono, keempat koreografer tersebut mengembangkan tarian yang berbeda dengan Sardono. Kata kunci: kontemporer, ketubuhan, training, latihan, pementasan

Novel Algorithm

By means of partial reconfiguration, parts of the hardware can be dynamically exchanged at runtime. This allows that streaming application running in different modes of the systems can share resources. In this paper, we discuss the architectural issues to design such reconfigurable systems. For being able to reduce reconfiguration time, this paper furthermore proposes a novel algorithm to aggregate several streaming applications into a single representation, called merge graph. The paper also proposes an algorithm to place streaming application at runtime which not only considers the placement and communication constraints, but also allows to place merge tasks. In a case study, we implement the proposed algorithm as runtime support on an FPGA-based system on chip. Furthermore, experiments show that reconfiguration time can be considerably reduced by applying our approach.

Event Based

The growth of the event sector is underpinned by the demand of organizing a business event.  Thus, it leads to an increase in economic and social impact. However, the problems from the growth of this sector potentially results from the use of several event materials, transportation and infrastructure development.  Organizing a green event is seen as one of the strategies to reduce the environmental impact.  Therefore, the aim of this paper is to explore the issues involved throughout the process of greening an event by applying Mair and Jago Model.  Semi-structured interviews were conducted with event managers from six Malaysia business event companies that encourage green practices during their event.  Findings suggest that impact, initiative, support and performance motivates event organizers in organizing a green event.  It has also been found that knowledge, resources and behaviour are the barriers faced by event organizers throughout the process of organizing a green event.  Based on the findings it appears that two important factors have emerged from the data collection and analysis that showed a deviation from the Mair and Jago Model, namely “impact” for the motivation element and “support” for the barrier element.  The main limitation of this study was the scope of the study; as it only focuses on business events.  However, as the main purpose of this study is to explore the issues of organizing a green event, it has been found that there are other issues need to be explored in other contexts and geographical area.  Apart from this, as this is a case study, it can only replicate according to the circumstances of this case study. However, this study can be generalized in terms of the theory that has emerged from it.  It is suggested that further research should explore more issues in other contexts and geographical areas.
