气流床气化炉在气化工业中得到了广泛应用,托砖架用于支撑气化炉耐火砖的重量,必须有足够的强度,温度是托砖架强度的重要影响因素。传统方法使用有限单元法计算,需要编制复杂的计算机程序。本文使用已有软件计算出托砖架最高温度点温度,对一个自适应神经模糊系统(ANFIS)进行训练,然后对未知数据进行预测,取得了准确的结果。 相似文献

This paper presents two concepts: asymmetric warfare and dissymmetric warfare. NATO and US Military operations in recent wars in Kosovo and Afghanistan are analysed by means of comparison with old Chinese strategic thinking. No‐Loss‐Strategy and virtual warfare as well as the transformation from asymmetric to dissymmetric and from dissymmetric to asymmetric warfare are reflected upon. 相似文献

An observing method for stator flux and rotor flux is presented. Based on the proposed flux observing method, a novel speed estimator has been designed. At last, the speed estimator combined with the flux observing is applied in the direct torque control system without speed sensor. The simulation results show that these methods can improve the accuracy of speed observing and the low speed performance of direct torque control system, and strengthen the robustness of system. 相似文献

Emotional support is known to provide psychosocial benefits for women with breast cancer, but women can experience a mismatch between support that is wanted and support that is received from their personal supporter. The role of wanted and unwanted support in psychosocial adjustment was examined in 79 women recovering from breast cancer. Four distinct patterns of desired support actions were found using cluster analysis. Patterns of wanted support were not related to better or worse psychosocial adjustment. However, a misalignment of support between the provider and the receiver significantly influenced psychosocial adjustment, and unwanted but received support (support commission) was uniquely associated with poor psychosocial adjustment. Clinical interventions using the support instrument could help match support providers' actions to receivers' preferences. (PsycINFO Database Record (c) 2010 APA, all rights reserved) 相似文献

This paper presents a methodology of using six-sigma quality tools for benchmarking of rapid prototyping & manufacturing (RP&M) processes. It involves the fabrication of a geometric benchmark part and a methodology to control and identify the best performance of the process to reduce the variablity in the fabricated parts. The approach is demonstrated with a case study based on the direct laser sintering (DLS) process for prototyping using plastic powder. In the case study an identified set of six-sigma/ statistical process control tools is employed to determine and best tune factors affecting the desired outcomes of the built parts. 相似文献

Demarcating distribution area of goods is often guided by the rule of thumb by business proprietors.However,this method seems to be unsuitable when the demand points increase to a certain large extent.The present work attempted to convert the problem of distribution area demarcation into a localized problem of warehouseing and networking,and tried to establish district-based planning mode based on location based heuristic (LBH).Two methods were used in this study:1) the manual method to construct the mathematical model and conduct simulation;2) the automatic method using TransCAD software of geographical information system (GIS) for simulation.By comparing the effects of the two methods,the research provides theoretical support for business proprietors to demarcate the distribution area rationally with the application of GIS system.The results show that GIS has very good graphics construction function to replace complex text,and the automatic demarcating mode with human-machine interaction provides a good business decision-making support. 相似文献
