Appropriate boundary conditions have been framed based on the physical conditions of the problem. The temperature profiles have been computed and the thermal changes in the breast have been analysed during the follicular and luteal phases of the menstrual cycle in different stages of its development. The finite element method has proved to be quite flexible and powerful in the present study as it was possible to incorporate the physiology of the breast in the proposed model to generate the thermal information of the breast due to benign changes occurring in the breast such as the menstrual cycle, etc.","PeriodicalId":266151,"journal":{"name":"Int.

For that reason, the Mexican government announced a couple of years ago the construction of a completely new one which is supposed to be operative in 2020 in its first phase. However, the technical issues and the economic downturn in the country jeopardise the project; for that reason, it is important to have alternatives that allow investing in a progressive fashion so that the investments are not lost or end up in useless infrastructure like the ones that have taken place in other parts of the world. The current work presents a simulation-based study of the alternative of using one of the runways of the new airport in a remote fashion in case the original project is delayed or even cancelled. The results indicate that the proposed infrastructure alleviates the congestion problem in the current airport, and at the same time allows the traffic growth with performance indicators similar to airports that have remote runways as in the case of Schiphol in The Netherlands.","PeriodicalId":266151,"journal":{"name":"Int.

To this end, two real players, i.e., a WEEE collection company and a treatment plant both located in the north of Italy, were preliminarily observed. Data about the incoming flow of WEEE and the production of recycled goods was retrieved from direct observations. Specific key performance indicators were determined and used to evaluate the performance of the existing network and of some alternative configurations. As it grounds on a real WEEE reverse logistics system, this study provides interesting proposals for future actions on WEEE management.","PeriodicalId":266151,"journal":{"name":"Int. J. Simul.

This paper introduces a new approach for modelling causal relationships between various ATM performance indicators, which can be used to predict, by means of simulation techniques, the evolution of airport operations scenarios. The analysis of reachable airport states is a relevant approach to design mitigation mechanisms on those perturbations which drive the system to poor KPIs.","PeriodicalId":266151,"journal":{"name":"Int.

The simulation framework is based on a modular concept with the core module GEPOC (generic population concept), developed within the DEXHELPP consortia project in Austria, parameterised for regional forecast. Demographic changes, their simulated effects on (re)-hospitalisation, changes in distance to service and the effect of changes in the diabetes mellitus prevalence are calculated as forecast for Austria, Slovenia, and Veneto region.

There are many actions that human tutors perform which make them remarkably effective, including the attention that they pay to the cognitive and affective states of the human students that they tutor, and the use of this knowledge to modify the way that they instruct the material. According to theoretical models, learner state data is used to inform instructional data and decisions, which then influences the learning of the student. Naturally, the data about student state must be available in order to be used to adjust the instruction. Success amongst operational systems, however, has not been observed with generalised modelling techniques. Individualised and adaptive modelling techniques from other domains in the literature present an alternative to the approach which is not observing significant operational success. This work investigates individualised adaptive models, validates the approach, and shows that it can produce models of acceptable quality, but that doing so does not obviate the experimenter from creating quality generalised models prior to individualising.","PeriodicalId":266151,"journal":{"name":"Int.

Practices such as the onshore power supply (OPS) may have relevant benefits but it has been argued that container terminal operators perceive a paucity of evidence that the benefits derived from the implementation of these practices exceed the investment costs. To this end, an advanced simulation-based decision support system is proposed in this article to represent a reliable test environment to simulate and compare different alternatives in terms of environmental impacts and economic sustainability. The implementation of an OPS system is considered as case study. Results show that an OPS system must consider the source of the electric power needed by ships at berth, i.e., coal, biofuels or renewable energies. The unit costs of 1 m3 of saved CO2 and NOX by implementing an OPS system are also calculated.","PeriodicalId":266151,"journal":{"name":"Int. J. Simul. Process.

The lower level, consisting of the delivery of goods in the form of raw materials and or finished products to customers on time, is vital as it enhances customers' loyalty. This could boost competitive advantages yielding to higher profitability of organisations over their rivals. However, to achieve and sustain these advantages, organisations need to identify and analyse the risks and their impacts on deliveries especially during strategic and operational decision making processes. Hence, modelling and simulation may be utilised as an effective tool to support decision making when planning delivery patterns. Consequently, a research is conducted in a logging company, Company 'L', to comprehend the way uncertainties affect deliveries. This article therefore uses a simulation model as a tool to boost managerial decision making, with reference to Company 'L', by identifying and analysing uncertainties and portraying their impacts on deliveries. This will enable the organisation to be agile and flexible enough to combat uncertainties.","PeriodicalId":266151,"journal":{"name":"Int. J. Simul. Process.

Therefore, simple rules and thresholds guide the routing decisions rather than extensive data collection and machine learning. In this paper, we optimise some of the thresholds governing the behaviour of a reactive and predictive routing algorithm by using the microscopic traffic simulator TraffSim. Microscopic traffic simulation is more exact than its macroscopic counterpart and very well suited to test the efficiency of a reactive and predictive routing algorithm. Unfortunately, it is also tremendously more computationally expensive, impairing the applicability of 'conventional' heuristic optimisation techniques like genetic algorithms or evolution strategies. Extensive use of surrogate models in an optimisation procedure is a promising alternative. Several variations of the efficient global optimisation (EGO) algorithm are tested and compared. Furthermore, a new type of surrogate model geared towards the parameter optimisation is presented.","PeriodicalId":266151,"journal":{"name":"Int. J. Simul. Process.

The proposed simulator is based on an interoperable architecture using the new MS2G paradigm and it designed for being federated by IEEE 1516 HLA with other systems. The paper presents its use as test-bed on a specific case study conducting experiments over the SPIDER virtual platform developed by simulation team. In facts these experiments were based on two university classes that performed tests and training experiences on multiple target functions including mission time, detection, classification and securing of injured people. The analysis included also use of innovative procedures based on autonomous systems. The obtained results highlighted improvements on the learning curves with respect to specific target functions. These results confirm the potential of this approach as a training strategy that combines medical skills with engineering to improve reaction capabilities and situation awareness during industrial crises.","PeriodicalId":266151,"journal":{"name":"Int.
