as an automated fashion for updating spatial metadata which is based on an ongoing research by authors on “Spatial Metadata Automation”. The paper firstly compares different methods of spatial metadata generation and focuses on an automation framework. This framework embraces three streamlines including create, update and enrich. Finally, a new synchronisation approach is introduced to address ...

this paper aims to recognise information security policies (isp) and their relationship with the effectiveness of the management information systems (mis) of the major palestinian universities in the gaza strip. the researchers used the descriptive analytical approach. they used a questionnaire as a research tool. they used a stratified random sample to explore viewpoints of the research sample...

We design and conduct an economic experiment to investigate the learning process of the agents under compound risk and under ambiguity. We gather data for subjects choosing between lotteries involving risky and ambiguous urns. Decisions are made in conjunction with a sequence of random draws with replacement, allowing us to estimate the beliefs of the agents at different moments in time. For ea...

in this paper, a new enhanced version of the particle swarm optimization (pso) is presented. an important modification is made by adding probabilistic functions into pso, and it is named probabilistic particle swarm optimization (ppso). since the variation of the velocity of particles in pso constitutes its search engine, it should provide two phases of optimization process which are: explorati...

This paper presents a novel hardware architecture based on generalized Hebbian algorithm (GHA) for texture classification. In the architecture, the weight vector updating process is separated into a number of stages for lowering area costs and increasing computational speed. Both the weight vector updating process and principle component computation process can also operate concurrently to furt...

This paper presents a software framework, PARIS (PARameter Identification System), developed for automated finite element model updating for structural health monitoring. With advances in Application Programming Interfaces (API) for modern computing, the traditional boundaries between different standalone software packages hardly exist. Now complex problems can be distributed between different ...

Even without sensory input, an animal can estimate how far it hasmovedby integrating its velocity, a process called path integration. The entorhinal cortex (EC) and hippocampus seem to be involved in path integration, and in an animal’s perceived location in space. However, path integration is highly susceptible to accumulating errors. A real animal avoids this problem by incorporating sensory ...

Processes that occur in many biological systems are not synchronous, but are governed by asynchronous updating. Although some previous models of multi agent systems have incorporated asynchronous updating in an informal or implicit way, the importance of asynchronous behaviour has been largely overlooked. However, the update scheme chosen is very important in determining the overall system beha...

In this note the author discusses the problem of updating forecasts in a time-discrete forecasting model when information arrives between the current period and the next period. To use the information that arrives between two periods, he assumes that the process between two periods can be approximated by a linear interpolation of the timediscrete forecasting model. Based on this assumption the ...
