The characteristics of early outbreak signal which are weak and behaved under uncertainties has brought to the development of outbreak detection model based on dendrite cell algorithm. Although the algorithm is proven can improve detection performance, it relies on several parameters which need to be defined before mining. In this study, the most appropriate parameter setting for outbreak detection...
New requirements for the validation of simulation models based on measurements in many grid codes show that existing generic approaches for generator and converter models of doubly fed generator systems (DFG) may not be accurate enough. The authors show that by applying a detailed analysis of the generator equations and the converter control design, a reduction of the model complexity is possible...
This paper focuses on one of the earliest steps in System of Systems (SoS) design aiming to meaningfully determine stakeholders' values or preferences. It recommends the plural problem definition and dynamic construction of stakeholder's values in the front end of design process. It suggests a method based on the probability theory to embed flexibility and tolerance, and construct a basic framework...
Real-world robots commonly have to act in complex, poorly understood environments where the true world dynamics are unknown. To compensate for the unknown world dynamics, we often provide a class of models to a learner so it may select a model, typically using a minimum prediction error metric over a set of training data. Often in real-world domains the model class is unable to capture the true dynamics,...
Multiuser voice conferencing platforms are more and more popular. Internet bandwidth is becoming very accessible, what makes voice over IP used on an everyday basis. Being able to communicate with multiple people at the same time can be beneficial, but on the other hand increases the need of coordination mechanisms. Determining a moderation scheme which is fair and efficient is not a trivial problem...
This paper presents a second look at the computation of the Medical Technology Score (MTS), a metric designed to convey the relative technical competence of a health facility. Modification of the score to reflect local disease burden is discussed, as are its intended interpretations. Extensive data collection on up-to-date equipment and personnel resources must be undertaken before the MTS can become...
The second leading cause of cancer related death in women is breast cancer, mostly diagnosed in the age group of 40–60. Breast cancer is the formation of lump in the breast, this the initial stage which is further followed by abnormal cell division and growth of malignant tumour. Mammography is the most powerful detector of breast cancer that can easily diagnose masses and micro-calcifications. Early...
Algorithmic trading (AT) strategies aim at executing large orders discretely, in order to minimize the order's impact, whilst also hiding the traders' intentions. Most AT evaluation methods range from running the AT strategies against historical data (back testing) to evaluating them on simulated markets. The contribution of the work presented in this paper is twofold. First we investigated different...
