In recent years, due to the overcrowding of Emergency Department (ED) and the growing concern in reducing the number of inpatient ward beds, it has become crucial to improve the capacity planning and control activities, which manage the patient flows from EDs to hospital wards. Bed Management has a key role in this context. This study starts by a collaboration with the Local Health Government (LHG)...
The ocean surface is part of the upper ocean which directly interacts with the overlying atmosphere and sea ice. Once oil spill happened due to an accident such as the oil rig pipe leaking and exploring, it would be unimaginable disaster to the oceanic environment, especially in the coastal area. If we can predict the direction along which the oil films floats over the marginal sea surface, the damage...
It is expected that international sea transportation will continue to increase as the world population increases. The International Maritime Organization (IMO) requires preparation of ship navigation efficiency management plans, including improvement in ship cruising methods such as appropriate ship trajectory selection. Moreover, shipping companies pay careful attention to fuel consumption and environmental...
The purpose of this paper is quantitative estimation of the reliability of digital microscopy systems for automated petrographic analysis. The proposed method consists in measuring the intensity of the three spectral components of the reflected light (red, green, blue) in each pixel of the investigated surface (frame) and using of methods of pattern recognition of images in geological and mineralogical...
This paper presents a framework to support the development of three-dimensional virtual scenarios for an operator training simulator for electrical systems. Given the need to represent a variety of scenarios of interest, this can be an effort and time consuming task. The proposed framework promotes a systematic approach when building scenarios and is supported by tools from the ontology-based domain...
The 2004 Indian Ocean tsunami and the 2011 Great East Japan tsunami left several lessons for future events. Both tsunami events confirmed the importance of early evacuation, tsunami awareness and the need of developing much more resilient communities with effective evacuation plans. To support reconstruction activities and efforts on developing resilient communities, tsunami evacuation simulation...
To discover the movement rules of soil particles around cutterhead during shield machine tunnelling, the discrete element model of shield machine tunnelling is established. The model is able to simulate the structure of shield machine, the pressure of ground, the excavation operation process and the flow process of soils. The cutterhead torque is obtained by running the model, which is accord with...
Over the past years Wireless Sensor Networks (WSNs) have been applied to a range of fields from military applications to medical and multimedia ones. Meanwhile, robots have managed to prove their necessity in cases where actuation is needed, therefore, achieving high accuracy tasks indeed. New prospects of collaboration for these two avant-garde technologies have already emerged and have been put...
A key technology problem with respect to approval testing and evaluation is that of simulating sea wave impact in shipborne weapons systems, both in terms of land-based and sea-based tests. There are two main methods in use at present: the first method is to build large-scale water pool, in which the shipborne weapons system under test is mounted to a special model ship; the second method is to simulate...
The proposition is connected with the research of the security or threatens referring to message decryption, user dishonesty, non-fresh nonce, uncontrolled information jurisdiction, etc. (security attributes), in network communication processes. Encrypted messages are usually sent in the form of protocol operations. Protocols may be mutually interleaving, creating the so called runs, and their operations...
Our position is that agent-based modelling is a potentially powerful complementary tool in the study of financial systems, especially where institutional behavioural factors and empirical data are incorporated. The work reported here concerns an agent-based model of a banking system focused on liquidity provision, principally the flows of cash between banks and other system actors. This model has...
The authors are studying backward simulators which trace from results to causes for comprehensive verification of system safety. It is not easy to make a backward simulation model because the forward model may not be expressed in a reversible formula, or it is not reversible in cases of multiple inputs or inclusion of internal state variables. In this paper, we propose a backward simulator which can...
Hair modelling is an important part of many applications in computer graphics. Since 2D hair strands represent the information of the hair shape and the feature of the hairstyles, the generation of 2D hair strands is an essential part for image-based hair modelling. In this paper, we present a novel algorithm to generate 2D hair strands based on a template matching method. The method first divides...
There has been a growing interest in recent years in development of computational intelligence methodologies that relate to nature-inspired computational methodologies and approaches to address complex real-world problems to which traditional approaches, are ineffective or infeasible. The essential to development of novel algorithms is modeling the phenomena of the nature in that way that they can...
