With the development of radiant floor system engineering applications in civil and agricultural buildings, an engineering problem has been gradually becoming urgent, that is how to match the terminal of a radiant floor system for changeable and flexible application. This problem is closely related to thermal performance of the floor. Therefore, it is very important and necessary to study the heat transfer process of the floor, and obtain the regulation and characteristics of heat transfer to solve it. As the core component of heat transfer in radiant floor system, the floor can be regarded as one kind of special heat exchanger. Based on the basic theory and parameters of heat exchanger, thermal performance can be analyzed and evaluated. Based on the application of thermal resistance in series, the heat transfer of multi-layer floor structure is equivalent to that of homogeneous structure, whose analytical solution and heat resistance of floor are obtained. Assuming that the heat conduction in pipes wall is one-dimensional problem, the thermal resistance of the wall is amended after the model based on the equivalent thermal resistance. Furtherly, combined with the basic theory of the thermal design of the heat exchanger, the heat transfer effectiveness ε is raised when the radiant floor is regarded as some kind of heat exchanger. According to the heat transfer effectiveness, the number of transfer units can be obtained, and then the ε-NTU (number of transfer units) method for thermal design of floor structure is creatively proposed, which is compared with the design graph and design tables in ASHRAE (American Society of Heating, Refrigerating, and Air-Conditioning Engineers) Handbook. Finally, the ε-NTU method for thermal design of floor structure was put into practice for the designs of radiant floor system in the buildings located in Beijing. According to the supply temperature provided and the heating load calculated, the total thermal resistance of floor structure was obtained, and then the parameters of floor layers and pipe spacing were determined. The experimental data indicate that the temperatures of the rooms meet the design requirements very well. It shows that the ε-NTU design method can be more convenient for the design of floor heat transfer structure with flexible application. The corresponding floor structure can be determined according to the supply temperature, indoor temperature and heating load, and the supply temperature can be determined according to the different floor structures. The floor surface temperature under the supply temperature and the floor structure can be checked. A new way of thinking for the floor thermal design is provided. [ABSTRACT FROM AUTHOR]

In order to improve magnetic resonance image (MRI) reconstruction quality, this paper proposed a hybrid reconstruction algorithm, which combined higher degree total variation (HDTV) and non-local total variation(NLTV).First, it decomposed the reconstructed MRI into constant area and detail area by a global gradient extraction scheme.Second, in each iteration, the hybrid reconstruction algorithm applied HDTV on the constant area firstly, then it applied the NLTV on the detail area.At last, the MRI reconstruction image was combining the constant area with detail area at the end of iteration. The experiments demonstrate that the proposed algorithm is superior to total variation algorithm, HDTV and NLTV.It not only removes noise effectively and preserves the texture and detail information better, but also greatly suppresses the staircase of the total variation.

High lead tin-bronze (ZCuPb22Sn1.5) was produced by centrifugal casting method. The friction and wear properties of the materials were investigated at fixed loads and friction speed，and the wear mechanisms were also analyzed. The results showed that the wear rate increases and the friction coefficient decreases with the increasing the load， the friction coefficient decreases rapidly and then trends to be stable as the loads increases to 120N when the friction speed is below 0.05m/s. Similarly， at the loads of 100N the wear rate increases and the friction coefficient decreases with the increase of the friction speed when the friction speed increases to 0.10 m/s， the friction coefficient decrease rapidly， and then trends to be stable as the friction speed increases to 0.20m/s. Then， with the increase of the fixed loads and friction speed， the solid lubrication film is damaged， the wear of the materials is severe and the wear rate unstably increases. In the process of friction and wear the Pb solid lubrication film on the worn surface is stable， and the materials have good antifriction and lower wear. [ABSTRACT FROM AUTHOR]

The composability of simulation models is the core of research of the theory and method of composable simulation. Based on the composition-oriented M&S framework, the significance of the "context" to composability evaluation was described. Through the formal definitions of the application context, the model context and their relationship with the composability, the validity of composability is to determine whether the model context of simulation models and their composition is true under the restriction of the application context, therefore, based on the interface pruning and behavior pruning in the model context, the conditions of model composition which meet the application requirements were put forward, and then the criteria for the four IO levels were induced. The criteria not only help to clearly describe the research level and content of composability evaluation, but also help to carry out the engineering practice of composable design and simulation models' maturity.

Boundary layer transition plays a significant role in the prediction of aerodynamic and aerothermodynamics characteristics of hypersonic vehicle. The commonly used correlation based on γ-Reθ transition model is implemented into a Reynolds-Averaged Navier-Stokes solver in order to evaluate its capability in hypersonic flows. The mean flow and turbulent flow equations are solved simultaneously based on the LU-SGS method. Three compressibility correction methods are adopted to simulate the hypersonic flows around a flat plate, a double wedge and a cone body. Results of Stanton number, heat flux on walls, contours of turbulence kinetic energy and intermittency factor are presented. The results of γ-Reθ transition model show better flow essential than that of full laminar or full turbulent results. The transition onset positions obtained by different compressibility methods under the same free stream turbulence intensity varied significantly. Compressibility correction based on local Mach number delays the transition onset greatly, while the correction of source term of turbulent kinetic energy equation improves the accuracy of heat flux on turbulent section of the wall. Rational selection of compressibility correction method should rely on the type of flow. Elaborate and reliable compressibility correction method still need to be further investigated.

To solve the poor performance of presented algorithm in solving the connected target coverage problem in directional sensor networks (DSN), this paper used distributed learning automata (DLA) to design a new scheduling algorithm. It employed the DLA to determine the sensors that should be activated at each stage for monitoring all the targets and transmitting the sensing data to the sink. It devised several pruning rules in order to maximize network lifetime. The proposed algorithm selected sensing nodes with as few overlapped targets as possible and avoided the selection of critical sensors as relay nodes so as to prolong the total network lifetime. Experimental results show that proposed algorithm can effectively resolve the connected target coverage problem, it is better than advanced algorithm in extending network lifetime.

OBJECTIVE: To explore the effects of simvastatin on tumor growth, blood coagulation in mice with colorectal cancer based on microRNA (miR)-181/ nuclear factor (NF)-κB pathway. METHODS: The colorectal cancer mice model was established by subcutaneous injection of human colorectal cancer cell line SW480, and 30 model mice were randomly divided into the control group, simvastatin low-dose group and simvastatin high-dose group. The simvastatin low-dose group and simvastatin high-dose group were intraperitoneally injected with 50 mg/ kg and 100 mg/ kg simvastatin, qd. On the 28th day, tumor growth, angiogenesis, coagulation indicators were analyzed. The expression levels of miR-181, IκBα and NF-κB mRNA and protein in tumor tissues were detected by quantitative reverse transcription polymerase chain reaction and western blotting. RESULTS: Compared with the control group, the tumor volume, mass, CyclinD1 protein, Ki67 protein, Bcl-2 protein, microvessel density, vascular endothelial growth factor (VEGF) levels, whole blood viscosity, IκBα and NF-κB mRNA and protein expression levels of the simvastatin low-dose group and simvastatin high-dose group decreased significantly, while Bax protein and miR-181 levels increased, plasma prothrombin time ( PT), activated partial thromboplastin time ( APTT) and miR-181 were prolonged significantly, with statistically significant differences ( P < 0. 05 ). The tumor volume, mass and microvascular density in simvastatin high-dose group were significantly lower than those in simvastatin low-dose group [(171. 74±19. 33) mm3 vs. (226. 52±26. 38) mm3, (0. 21±0. 03) g vs. (0. 28±0. 04)g, (9. 77±1. 85)% vs. (16. 39±2. 11)%], CyclinD1, Ki67 and Bcl-2 protein levels, VEGF levels, whole blood viscosity, expression levels of IκBα and NF-κB mRNA and protein were significantly lower than those in simvastatin low-dose group; the levels of Bax protein and miR-181 were significantly higher than those of simvastatin low-dose group, PT and APTT were significantly longer than those of simvastatin low-dose group, the differences were statistically significant (P<0. 05). CONCLUSIONS: Simvastatin may inhibit tumor growth and angiogenesis in colorectal cancer model mice by regulating the miR-181/ NF-κB pathway, and alleviate blood hypercoagulability.
