Buried culverts have been in service more than half a century and their age raises questions about reliable serviceability for the new standard vehicles. The gross weight axle spacing of these trucks play an important role on performance buried where culvert is covered with shallow fill heights. Field live load tests were conducted by driving loaded truck over some at slow speed while recording...

generally human vision system searches for salient regions and movements in video scenes to lessen the search space and effort. using visual saliency map for modelling gives important information for understanding in many applications. in this paper we present a simple method with low computation load using visual saliency map for background subtraction in video stream. the proposed technique i...

For the dimensioning of shared resources, the latency and utilization of the service is a vital design characteristic. The throughput and latency is as important for e.g. network streaming applications as in e.g. (small-scale) distributed embedded systems interacting with physical processes. Calculating latencies of a system involves the analysis of the queue sojourn times. The analysis of queu...

Analyses of Power Output of Piezoelectric Energy Harvesting Devices Directly Connected to a Resistive Load Using a Coupled Piezoelectric-Circuit Finite Element Method Meiling Zhu, Emma Worthington and James Njuguna Department of Materials, Department of Sustainable Systems Cranfield University, Bedfordshire, MK43 0AL UK Abstract A coupled piezoelectric-circuit finite element model (CPC-FEM) is ...

The managers need to have a reasonable guide on the operation and management in district heating system (DHS), so it’s very necessary to predicting the heat load for DHS. In this paper, the relationships between the heat load and weather conditions have been researched in order to determine the inputs variables and output variable of the future heat load prediction model. Using the given data f...

The advanced transient concrete model (ATCM) is an extended model for concrete in compression at elevated temperature that incorporates elastic, plastic and creep strain as a function of temperature and stress history. The ATCM is applied with the material model of the thermal induced strain model. The non-linear model comprises thermal strain, elastic strain, plastic strain and transient tempe...

The electrical distribution network operation depends considerably on network busloads, which are formed by active and reactive power of the substations. Therefore, the network operation variables such as power flows, currents, voltages, etc. change similarly as do loads. It is possible to notice periodicity, temperature dependency, stochasticity etc. This paper describes the distribution netwo...

Probabilistic forecasting of electricity demand (load) facilitates the efficient management and operations energy systems. Weather is a key determinant load. However, modelling load using weather challenging because relationship cannot be assumed to linear. Although numerous studies have focussed on forecasting, literature uncertainty in while estimating probability distribution scarce. In this...

In this paper, experimental responses of the clamped mild steel, copper, and aluminium circular plates are presented subjected to blast loading. The GMDH-type neural networks (Group Method of Data Handling) are then used for the modelling of the mid-point deflection thickness ratio of the circular plates using those experimental results. The aim of such modelling is to show how the mid-point de...

The employment of network-based technologies, such as the WWW and middleware platforms, significantly increased the complexity of distributed application, as well as the Quality-of-Service requirements for the underlying network. Distributed application modelling is nowadays far more demanding than network modelling, where numerous solutions are already employed in commercial tools. We introduc...
