Rapid pace of global urbanization has posed significant challenges to urban transportation infrastructures. Existing urban transit systems suffer many well-known shortcomings, where public transits have limits on coverage areas, and fixed schedules, and private transits are expensive and fail to timely meet the demand needs. We thus envision a Cloud-Commuting system, that employs a giant pool of centralized...
With rapid growth in smart phones and mobile data, effectively managing cellular data networks is important in meeting user performance expectations. However, the scale, complexity and dynamics of a large 3G cellular network make it a challenging task to understand the diverse factors that affect its performance. In this paper we study the RNC (Radio Network Controller)-level performance in one of...
Because of the fast and convenient accessing to network, commodity management and selling with network has been widely applied to various kinds of industries. Accordingly to jewelry, which is different from other commodities, a jewelry management and sell system based on .NET MVC framework was designed and built on the visual studio 2010 development platform with SQL server 2008 express database in...
In this paper, we propose a novel trust management scheme for improving routing reliability in wireless ad hoc networks. It is grounded on two classic autoregression models, namely Autoregressive (AR) model and Autoregressive with exogenous inputs (ARX) model. According to this scheme, a node periodically measures the packet forwarding ratio of its every neighbor as the trust observation about that...
Based on the former researches by minimum method on the impacts of the ecological impact factors (water depth, water temperature, substrate, et al) on suitability indices of adult fish growth, spawning and hatch, we calculate the habitat suitability indices by the parallel method, and use different simulation equations (polynomial equation, exponential equation, logistic equation, et al) to compare...
The use of information technology on the clinical diagnosis has become a hot study issue in recent years. In this paper, based on the dynamic model of Hepatitis B Virus and patients' clinical testing data, we identify the key parameters of HBV dynamic model. With the help of this parameter identification, the patients' developing trends of Hepatitis B Virus are simulated by computer to provide some...
Today's large campus and enterprise networks are characterized by their complexity, i.e. containing thousands of hosts, and diversity, i.e. with various applications and usage patterns. To effectively manage and secure such networks, network operators and system administrators are faced with the challenge of characterizing, profiling and tracking activity patterns passing through their networks. Because...
A game-based training system usually has its specific purpose. In our work, the system is designed for the mine accident rescue troop. When a mine accident happens, the conditions in the mine are extremely abominable, so the members are required not only to master the basic professional knowledge and skills but also to have good psychological diathesis, which are exactly our goals of designing this...
Adsorption and separation of the binary mixture of CO2 and CH4 in erionite, mordenite and clinoptilolite are studied through a computer simulation technology-molecular simulation, and the simulation results showed a good agreement with the experimental data. The mechanism for the process was discussed and some conclusions for the process design were made.
Firstly, the factors influencing industrial electric power demand are analyzed. Secondly, the changing law of power consumption intensity and the character of industrial electric power consumption are studied based on the power consumption and the value of industrial output. Finally, a model of power demand is established based on panel data, in which the influence of policy of saving energy is considered...
The simulation technology is one of the key technologies in computer hardware circuit design. The Commonly used simulation strategies are all used in systems which have a determined evolution status, that is, it is certain on the there is a pre-determined happen time on events and whether the event happens is also pre-determined. The nature of a pre-determined happen time makes these strategies vulnerable...
An architecture for online discovery quantitative models system of service performance management was proposed. The system was capable of constructing the quantitative models without prior knowledge of the managed elements. The model can be updated continuously in response to the changes made in provider configurations and the evolution of business demands. Due to the existence of strong correlation...
