With the development of urbanization, the construction of town informationization is becoming more and more urgent and important in China. At present, the consciousness of town informationization is not deep; the information application is not of large scale; information-based talents are not enough and the information industry is of low level. Besides, lots of towns don’t know what to do and h...

We present a new protocol for maintaining replicated data that can provide both high data availability and low response time. In the protocol, the nodes are organized in a logical grid. Existing protocols are designed primarily to achieve high availability by updating a large fraction of the copies which provides some (although not signiicant) load sharing. In the new protocol, transaction proc...

Situation Awareness, and how systems can be designed to support it appropriately, have been a focus of study in dynamic, safety critical contexts such as aviation. The work reported here extends the study of situation awareness into the domain of Emergency Medical Dispatch (EMD). The study was conducted in one of the largest ambulance services in the world. In this study, we encountered develop...

We explore the possibility of automatically constructing hierarchical schemas from low-level sensory data. Here we suggest a hierarchical event network to build the hierarchical schemas and describe a novel machine learning method to learn the network from the data. The traditional methods for describing schemas define the primitives and the relationships between them in advance. Therefore it i...

Die High Level Architecture (HLA) ist ein Ansatz der verteilten Simulation. Im Mittelpunkt des Beitrags steht die Nutzung dieser Architektur für verteilte Simulationsmodelle von Fertigungsprozessen. Es wird eine prototypische Federation aus heterogenen Federates vorgestellt, wobei sich die beteiligten Federates hinsichtlich ihrer Funktionalität, ihrer Implementationssprache und ihres lokalen Ze...

This paper presents a novel textile wearable antenna that has been designed to operate at Wi-Fi bands of 2.4GHz & 5.8GHz. Antenna performance in free space environment showed Gain of 1.8dBi at 2.4GHz and 4.5dBi at 5.8GHz. However, performance deteriorated when antenna was operated near human body which is lossy and complex in nature. For mitigating the human body effect on antenna performance, ...
