constringency การใช้

• Bear the heat , can bear 230 heat but do not take place the constringency
• 5 . make some improvements on bp neural network to quicken the network constringency speed
• Because the optimization result is discrete , excellent individual protect plan was adopted to quicken constringency
• Power flow calculating , power loss and reactive power optimization analysis calculate fast and have credible constringency
• Levenberg - marquart optimized algorithm was used to learn the network , and its constringency is rapid
• The experimental results indicate that it is easy to be realized , can save the calculating cost and improve the constringency speed
• According to the low speed of constringency and high complexity of training methods in large scale training , particle swarm algorithm is brought forward to solve the problem
• Meanwhile the improved algorithm to solve the problems of bp as slow constringency and the trap of regional minimum . finally the thesis detailedly describes the design of neural network of bp
• But this kind of constringency transform because of its inner part not even stress and all control functions exist with exterior , and make concrete produce to pull - stress and pull - strain
• In the design process of the project , firstly the principle scheme is figured out with the theory of " black box " . constringency is done after the sub - functional solutions are acquired
• This arithmetic combined the rules of the accomplishment of the genetic algorithm and the rules of the traditional fuzzy clustering , so it can not only enhance the performance of clustering analysis , but also accelerate its constringency
• The aerodynamic design of curve of nozzle adopts perfect gas cresco method to calculate non - existence glutinous model surface , the correct boundary layer of the nozzle wall side adopts sivells - payre method , and the calculation of constringency part of the nozzle adopts stock formula
• This paper not only adopts the adaptive neuron network pid arithmetic for the purpose of distinguish system parameters , but also brings forward expert system control ruler in order to overcome the disadvantage of slow speed constringency of neuron network on the basis of neuron network pid arithmetic
• Firstly , the wavelet neural network is established to compress ecg data . the result shows that the given compression algorithm has good performance of fast constringency speed and highly compression radio . the network reserve the vital information about ecg data so that it can help to diagnosing
• Construction of a mass concrete is in the construction process , because of cement let out in large quantity hydration heat and surface of a mass concrete let out heat , make its temperature , humidity cause to ascend and descend , and it causable constringency transform will be unavoidable
• On the contrary , fuzzy system is based on an easily expressed way - " if - then " , which is easily accepted by people . its constringency is great , because fuzzy system is based on the knowledge of experts . however , it is a challenge on how to create and adjust the membership functions and fuzzy rules automatically
• This paper studies nonlinear dynamic problems of tall building structures , first , constitutes linear dynamic equation and elasto - plastic dynamic equation of structure by using qr method , later , solves the dynamic equation by using spline unconditional stable algorithm , last , programs corresponding computer programs with c program language , and calculates some example and a tall building in constructing the courses and the results prove that qr method is not only simple in calculating and fast in constringency rate , but also precise , that qr method is a effective and economic new method
• At last , it ' s the analysis the internal character of real estate fluctuation in china , there are such problems as lack consume demand , the simple expansion or constringency of the quantity type ; product inclination motion ; obvious of policy period type motion ; the market mechanism is not perfect ; district development pole unb
• The productions include : 1 . the investigation of crackss of masonry structures , the characteristic and the reason on cracks of wall ; 2 . the limited element analysis about datum of brick - wall the relation between the maximal stress in wall and the relative sedimentation of foundations , the relation between the cracks form in wall and inner stress , the validity of limited element mode ; 3 . the limited element analysis about the relative sedimentation of foundations , the influence of ratio of length and height , foundations rigidity , groundsill rigidity on the inner stress in wall ; 4 . the limited element analysis about the influence of temperature on wall cracks and the influence of space between extension cracks , difference in temperature on the inner stress in wall ; 5 . the analysis about the cracks rule because of temperature , the contrast between the result and the simulant result ; 6 . the study about the influence of cracks of masonry structures because of constriction stress , the experience of dealing with constriction cracks in the domestic and the foreign ; 7 . the advice of avoiding cracks because of the asymmetric sedimentation temperature , constringency in design and construction
