in this paper, dissimilar resistance spot welding of aisi 1075 eutectoid steel to aisi 201 stainless steel is investigated experimentally. for this purpose, the experiments are designed using response surface methodology and based on four-factor, five-level central composite design. the effects of process parameters such as welding current, welding time, cooling time and electrode force are inv...

There are several types of security systems, which focus on detecting, mitigating and responding to incidents. Current response systems are largely based on manual incident response selection strategies, which can introduce delays between detection and response time. However, it would be beneficial if critical and urgent incidents are addressed as soon as possible before they jeopardised critic...

The study presented demonstrates the modeling of a commingled waste plastics blend. The approach is based on statistically designed mixture experiments and regression analysis. Through the evaluation of a specific array of test points, mathematical models and response surface plots were developed which describe the degree of influence and relationship of the formulation vari­ ables.

This paper presents an alternative visualization tool for headrelated transfer functions (HRTF’s) which represents HRTF data sets as magnitude spatial frequency response surfaces. Qualitative analysis of HRTF data is easier in the spatial domain than in the magnitude frequency domain and allows quick comparisons between different subjects’ HRTF sets. In addition, these surfaces exhibit many wel...

The main goal of the rule space method is to classify examinees into the closest ideal attribute mastery patterns and to assigned appropriate attribute mastery probabilities to them based on their item response patterns. The quality of pattern classification and probability assignment depends on the validity of the proposed attributes and the Qmatrix. The rule-space method provides the quality ...

This paper presents a taxonomy of existing approaches for using response surfaces for global optimization. Each method is illustrated with a simple numerical example that brings out its advantages and disadvantages. The central theme is that methods that seem quite reasonable often have non-obvious failure modes. Understanding these failure modes is essential for the development of practical al...

Intrusion response systems aim to provide a systematic procedure to respond to incidents. However, with different type of response options, an automatic response system is designed to select appropriate response options automatically in order to act fast to respond to only true and critical incidents as well as minimise their impact. In addition, incidents also can be prioritised into different...

In this study, a simulated annealing approach is developed to find optimal police patrol district design using a discreteevent simulation to evaluate the performances of districting plans, such as average response time and workload variation among districts. Similar to the solution neighborhood definition in an existing simulated annealing approach, the new solution (districting plan) in each i...
