The changing rules of influencing factors, such as luffing coefficient, eccentric coefficient, overflow area and relative sliding velocity, are analysed. With the amplitude coefficient and eccentric coefficient as decision variables, the paper optimises the equatorial short hypochromic curve to, get the best ratio of each head of the parameters and end line type.","PeriodicalId":266151,"journal":{"name":"Int.

In these systems, we have to deal with the problem of rescuing a high number of people of different ages, sex, physical characteristics, etc. Furthermore, this process mostly runs in buildings with different constraints like locations of the rows of shelves, exit gates, etc. On one hand, in order to deal with disasters such as fire propagation, studying this kind of system using a dynamic model has a great importance in order to avoid the maximum of casualties. On the other hand, the model that represents this kind of system must take into account several factors such as time, the building's characteristics and people's characteristics. In this study, an agent-based model has been designed to visualise the dynamic system behaviour via these internal entities that often interact. Additionally, we use some dynamic data mining methods such as Monte Carlo method to calculate the stable characteristics of this model via probabilistic approach.","PeriodicalId":266151,"journal":{"name":"Int.

The results show that elliptical cross-section mufflers show almost the same muffling effect as square cross-section mufflers, while square cross-section mufflers are more suitable for mass production; the length of the first cavity and the overlapped section of the insertion pipe present a remarkable noise reduction on low- and mid-range frequency; shortening the distance between the 1/4 wavelength pipe and the main pipe's confluence is more conducive to noise reduction; the addition of dissipative materials improves the muffling performance. Based on the above structure, a simulation model of impedance composite muffler was designed, with its A-weighting noise level dropped from the original 92.2 dB to 59.7 dB, thus achieving a good noise reduction effect.","PeriodicalId":266151,"journal":{"name":"Int.

Agents in the Cogent language are specified by a domain-specific language (DSL). The DSL provides the syntax for specifying the decision-making strategy along with its cognitive coherence model. The framework also provides the ability to model complex hierarchical cognitive network structures.

During the identification process, fuzzy analytic hierarchy process and fuzzy integrated evaluation are employed to identify the traffic condition on the arterial road; according to the fuzzy logic scheme, a proper coordination strategy is then generated based on the resulting identification of each way of the artery. To verify the effectiveness of the proposed method, a numerical experiment is carried out by using the microscopic traffic simulation software VISSIM, where a traffic flow simulation system is generated according to the real-time traffic data. The comparison results show that the proposed model works well to fit with the actual operating condition of the arterial traffic and the proposed coordination strategy can provide a better performance for the traffic management.","PeriodicalId":266151,"journal":{"name":"Int.

Based on theory of planned behaviour, we explore how local task self-efficacy and IT self-efficacy evolve with a computational model. The simulation results of the aerospace industry show that the organisation will emerge to a non-balanced state of development. Moreover, sites which form the distributed organisation will evolve to the independent locations in the end. For overcoming these situations, the study proposes a strategy - 'resisting foreign aggression home safe'. Moreover, a high rate of global tasks accomplishment can be achieved by improving members' IT self-efficacy, which brings in more communication and coordination between separated sites. For distributed organisations, the higher and the lower coordination are not rewarding, while the high local task self-efficacy and the moderate IT self-efficacy are beneficial.","PeriodicalId":266151,"journal":{"name":"Int.

Hosting discrete event system specifications (DEVS) models, these AmI servers and their communication protocols are different, miscellaneous and require interoperability. The triple-space computing (TSC) paradigm addresses interoperability by sharing information represented in a semantic format through a common virtual space. In this paper, we present DEVSServer, a fully distributed TSC simulation server solution (middleware) designed to meet the needs of parallel and distributed discrete event simulation. DEVSServer defines a service oriented architecture (SOA) interface for the TSC operations. This interface complies with DEVS formalism and focuses on simplicity, conviviality and modularity, so that a single or many simulations that support different models can still interact. To assess DEVSServer, we provide a tuberculosis epidemic model simulation in time-varying temporal network with genetic programming immunisation strategy approach.","PeriodicalId":266151,"journal":{"name":"Int.

In this paper, the concept of step height is introduced in a creative way, and a three-dimensional PDR model based on gait recognition is proposed, which makes it possible to locate indoor three-dimensional space. The three-dimensional PDR model uses an improved method of step detection and the average accuracy of the model is higher than the traditional 2D PDR model.

In this work, we present a normalised dynamics expressed in terms of dimensionless ratios. Our analysis and simulation of the passive bipedal gaits is realised mainly through bifurcation diagrams where a normalised leg length discrepancy is adopted as the bifurcation parameter. We report the exhibition of complex behaviours, namely the period-doubling bifurcation (PDB), the cyclic-fold bifurcation (CFB), the period-doubling route to chaos, the period-remerging scheme, the boundary crisis (BC), etc. We demonstrate also the exhibition of the Neimark-Sacker-2 bifurcation by investigating the tendency of the characteristic multipliers of the Jacobian matrix of the Poincare map.","PeriodicalId":266151,"journal":{"name":"Int.
