Dynamic Change Impact Analysis For Maintaining And Evolving Agent Systems, Hoa Khanh Dam, Aditya Ghose
Dynamic Change Impact Analysis For Maintaining And Evolving Agent Systems, Hoa Khanh Dam, Aditya Ghose
Faculty of Engineering and Information Sciences - Papers: Part A
In contrast to an increasing number of agent-based applica- tions in various domains, there has been very little work on maintenance and evolution of agent systems. This paper ad- dresses this gap with a focus on change impact analysis, i.e. estimating the potential eects of changes before they are made as an agent system evolves. We propose a technique for performing impact analysis in an agent system using dy- namic information about agent behaviour. Our approach builds a representation of an agent's behaviour by analyzing its execution traces which consist of goals and plans, and uses this representation to estimate …
Thermal, Microstructural And Mechanical Coupling Analysis Model For Flatness Change Prediction During Run-Out Table Cooling In Hot Strip Rolling, Xiao-Dong Wang, Fei Li, Zheng-Yi Jiang
Thermal, Microstructural And Mechanical Coupling Analysis Model For Flatness Change Prediction During Run-Out Table Cooling In Hot Strip Rolling, Xiao-Dong Wang, Fei Li, Zheng-Yi Jiang
Faculty of Engineering and Information Sciences - Papers: Part A
Non-uniformity of temperature distribution across strip width direction is the ultimate reason why the flatness defect occurs on the strip after cooling process although the strip is flat at the exit of finishing mill. One thermal, microstructural and mechanical coupling analysis model for predicting flatness change of steel strip during the run-out table cooling process was established using ABAQUS finite element software. K Esaka phase transformation kinetics model was employed to calculate the phase transformation, and coupled with temperature calculation using the user subroutine program HETVAL. Elasto-plasticity constitutive equations of steel material, in which conventional elastic and plastic strains, thermal …
Analysis Of Temperature Field In Liquid-Solid Bimetal Casting Of Laminated Metal Composite, Xingjian Gao, Dongbin Wei, Zhengyi Jiang
Analysis Of Temperature Field In Liquid-Solid Bimetal Casting Of Laminated Metal Composite, Xingjian Gao, Dongbin Wei, Zhengyi Jiang
Faculty of Engineering and Information Sciences - Papers: Part A
In order to improve the low toughness and poor crack resistance of high chromium cast iron (HCCI), the laminated metal composite (LMC) consisting of HCCI and carbon steel has received increasingly attentions in modern industries. Considering that the controllable temperature field at interface of LMC is a key issue in liquid-solid bimetal casting process, a three layered finite element method (FEM) model has been proposed. The influence of parameters including pouring temperature - Tpour, preheating temperature - Tpre and effective volume ratio - VRe on temperature field are discussed. Simulation results show that the temperature at the interface between two …

Cannabis use is highly prevalent among people with schizophrenia, and coupled with impaired cognition, is thought to heighten the risk of illness onset. However, while heavy cannabis use has been associated with cognitive deficits in long-term users, studies among patients with schizophrenia have been contradictory. This article consists of 2 studies. In Study I, a meta-analysis of 10 studies comprising 572 patients with established schizophrenia (with and without comorbid cannabis use) was conducted. Patients with a history of cannabis use were found to have superior neuropsychological functioning. This finding was largely driven by studies that included patients with a lifetime …
