New parallel program synchronization mechanisms are presented. A specialized synchronizer process, or a hierarchy of such processes, gather information about process states and construct Strongly Consistent Global States, using time interval timestamps. Global predicates evaluated by synchronizers can cause synchronization signals to be sent to processes, the signals trigger asynchronous computation activation or cancellation. The proposed framework is integrated with a message passing system - it is added to the GRADE graphical parallel programming environment to enhance its message-passing based features. Architecture and implementation of the enhancement are discussed.

Central Air Conditioning

Air conditioner unit which is a significant part of central air-conditioning is a multiinput-multioutput system.Because the input quantity of it is related with each other and influenced by multifarious interference, an ideal control effect is unavailable by general control method. It is also the main unit of energy consumption, so the refrigeration effect and the energy consumption of the central air-conditioning are determined by the control effect and efficiency of it. A neural network model is made according to the unit of air handing and controlled by the strategy of fuzzy-PID. It is proved by experiment that favorable control effect is available in case that the fuzzy-PID control strategy meets requirements when either there is interference or the target quantity changes.

Purpose The purpose of this paper is to characterize and understand the effects of polymer binder, thixotropic agent, solvent and organic medium content on the rheological properties of silver pastes for screen printing front electrode films of solar cells. Design/methodology/approach Dispersions of silver particles (surface modified with oleic acid) in ethyl cellulose (EC) polymer solutions with and without thixotropic agent were prepared, and yield stress values were measured by setting shear stress to characterize the inter-particle interaction strength of pastes. Steady-state flow, three interval thixotropy shear test and oscillatory measurements were conducted to study the effect of EC polymer and thixotropic agent on viscosity, structure rebuilding and viscoelastic properties of electrode pastes. The effect of solvent was studied by investigating the steady viscosity of cellulose acetate butyrate (CAB) polymer solutions and Ag dispersions. Findings Weak flocculation network of silver particles was produced because of depletion flocculation. Besides the interaction between thixotropic agent micelles, EC polymer also has a significant interaction with thixotropic agent. Merely increasing EC polymer or thixotropic agent content is not the best way to prevent the layer printed from laying down. The effect of solvent on the viscosity of paste is mainly attributed to the difference of hydromechanics radius and configuration of CAB polymer in solvents. With the increase of organic medium content, the properties of electrode pastes were converted from rigidity to flexibility. Originality/value It is still a challenge to obtain high-quality front electrode films for crystalline silicon solar cells by screen printing, because of the difficulty in reducing shadowing losses while ensuring a low series resistance and high filling factor. The paste rheological properties are the key properties related to the paste’s passing ability through the meshes and resistance of paste spreading on the substrate. Organic medium as an important component of the paste is acknowledged to be used to tailor the paste’s rheological properties and have a great role in screen printing.

The Relationship

Objectively and reliably determined indicators of rheological properties of the dough were identified using the alveograph device to create a system of classifications of wheat and flour from it for the intended purpose in the future. The analysis of the relationship of standardized quality indicators, as well as newly developed indicators for identifying them, differentiating the quality of wheat flour for the intended purpose, i.e. for finished products. To do this, we use mathematical statistics methods.
