Generally, the accuracy stability of a precision motorized spindle unit is influenced by its structural thermal balance behaviors (power matching degree heat generation–dissipations). For accurate analysis this transfer based on temperature detections, paper describes method constructed with numerical simulation technology and proposed genetic algorithm-extreme learning machine (GA-ELM) algorit...

The charge or barion number balance function in the relative azimuthal angle of a pair of particles emitted in ultrarelativistic heavy ion collisions is studied. The ππ and pp̄ balance functions are computed using thermal models with two different set of parameters, corresponding to a large freeze-out temperature and a moderate transverse flow or a small temperature and a large transverse flow. ...

Instruments flown on the Pioneer Venus orbiter and probes measured many of the properties of the atmosphere of Venus which control its thermal balance and support its high surface temperature. Estimates based on orbiter measurements place the effective radiating temperature of Venus at 228 ñ 5 K, corresponding to an emission of 153 ñ 13 W/m 2, and the bolometric Bond albedo at 0.80 ñ 0.02, corr...

This paper examines some experimental evidence for coupling between particle and energy anspor t in tokamak plasmas and presents analytical and numerical investigations of this type of transport. This coupling generally leads to discrepancies between the effective thermal diffusivities inferred from analyses of power balance and perturbation measurements. Such discrepancies have been observed e...

A model of the energy balance of the dayside ionosphere of Venus is presented. Calculations of the dayside electron and ion temperature profiles are carried out and compared with data from experiments on the Pioneer Venus orbiter. The coupled heat conduction equations for electrons and ions are solved for several values of the solar zenith angle. It is shown that thermal conductivities are inhi...

We consider stochastic particle acceleration in plasmas around stellar mass black holes to explain the emissions above 1 MeV from Galactic black hole candidates. We show that for certain parameter regimes, electrons can overcome Coulomb losses and be accelerated beyond the thermal distribution to form a new population, whose distribution is broad and usually not a power law; the peak energy of ...

This paper reports on the modelling of a commercial 1.2 kW proton exchange membrane fuel cell (PEMFC), based on interrelated electrical and thermal models. The electrical model proposed is based on the integration of the thermodynamic and electrochemical phenomena taking place in the FC whilst the thermal model is established from the FC thermal energy balance. The combination of both models ma...

The traffic and thermal problems of high performance three-dimensional Network-on-Chip (3D NoC) system become more unbalanced because of chip stacking and applied minimal routing algorithm. To make the temperature under a certain thermal limit, the overheat nodes are throttled by run-time thermal management (RTM). Therefore, the network topology becomes a Non-Stationary Irregular Mesh (NSI-Mesh...

With the development of quantitative remote sensing, regional evapotranspiration (ET) modeling based on the feature space has made substantial progresses. Among those feature space based evapotranspiration models, accurate determination of the theoretical dry/wet lines remains a challenging task. This paper reports the development of a new method, named DDTI (Determination of Dry line by Therma...
