Queueing Modelling is proposed in the domain of Intelligent User Interfaces and, more generally, in the field of Human-Computer Interaction. It is argued that Queueing Modelling can facilitate assessment of the current state and prediction of the future behaviour of user-computer interaction. This assessment can be used as the basis for adaptations either at design-time or at run-time, and can ...

Enterprise application landscapes are complex and hard to manage systems. Enterprise models abstract from this complexity and seek to capture relevant information to cope with business requirements, i.e., increase flexibility while reducing costs of IT. Recent automated approaches focus on utilizing existing information sources. We identified two issues in current approaches. First, in line wit...

Abstract Purpose-The purpose of this paper is to review a sample of the literature relating to Interpretive Structural Modelling (ISM) and its deployment for modelling purposes in the area of supply chain management (SCM). Design/methodology/approach- The literature is examined from the three perspectives. First, concept of ISM and examines ISM as modelling technique. Second, use of ISM by ...

This paper presents a parallel approach to estimate the parameters in the heat loading of a district heating system by use of the traditional particle swarm optimisation (TPSO) on the Graphic Processing Unit (GPU) using OpenCL. The running time of the algorithm is greatly reduced compared to running on CPU. The heat load is approximated by the sum of time dependent and temperature dependent com...

People with larger brains tend to score higher on tests of general intelligence (g). It is unclear, however, how much variance in intelligence other brain measurements would account for if included together with brain volume in a multivariable model. We examined a large sample of individuals in their seventies (n = 672) who were administered a comprehensive cognitive test battery. Using structu...

Renewable energy provides 20% of electricity generation worldwide. Hydroelectric power is the cheapest way to generate electricity today. It provides almost onefifth of the electricity in world. Hydropower is produced in more than 150 countries. The main objective of this paper is modelling and analysis of the effects of the power system stabilizer (PSS) for load frequency control (LFC) system ...

This paper describes the finite element modelling, dynamic testing and finite element model updating of a newly constructed, 35m span, cable-stayed footbridge. A numerical simulation, using an updated FE model, was conducted to evaluate the accelerations that would be induced by a walking pedestrian. The results from the simulation were compared to corresponding experimental measurements, and w...

Subject of this analysis is to show how storage is operated optimally under renewable and load uncertainty in the electricity system context. We estimate a homogeneous Markov Chain representation of the residual load in Germany in 2014 on an hourly basis and design a very simple dynamic stochastic electricity system model with non-intermittent generation technologies and storage. We compare the...

In many data grid applications, data can be decomposed into multiple independent sub datasets and schedule for parallel execution and analysis. Divisible Load Theory (DLT) is a powerful tool for modelling data-intensive grid problems where both communication and computation load is partitionable. This paper presents an Adaptive DLT (ADLT) model for scheduling data-intensive grid applications. T...

This article describes the influence of the kind of membership function on the accuracy of fuzzy logic forecasting model in the local power system. Fuzzy logic approach overcomes some problems related to practical implementations of traditional modelling and forecasting methods. This qualitative method of load forecasting can incorporate imprecise and ambiguous information in reasoning. The com...
