Numerical Calculations and Cold Tests for Flow Fields of a 220t/h Retrofitted Oil-Boiler

In this paper, cold simulation experiments and numerical calculations are conducted to predict 3 D flow field aerodynamics for an oil furnace after being retrofitted due to its fuel variation. K ε model and SIMPLE program under body fit coordination (BFC) system, in which TTM non orthogonal method is used to control the irregular geometric boundary, are adopted to solve the control equations. Model tests are conducted to check the calculation results, showing that they are in agreement with each other. Three different alternatives with different side window locations are also calculated to optimize the designs. The field retrofitting results show that the combination of cold tests with numerical calculations has prosperous application in retrofitting or renewing medium and small boilers.

Optimizing selection of bridge raft based on fuzzy matter-element model and combination weighting

It＇ s a necessary selection to support the maneuver across Yangtze River by floating bridge constructed by portable steel bridge and civilian ships. It is a comprehensive index for the scheme of bridge raft, containing a variety of technical factors and uncertainties. The optimization is the selection in the constructing time, quantity of equipments and man power. Based on the calculation result of bridge rafts, an evaluating system is established, consisting of index of spacing between interior bays, raft length, truss numbers, operation difficulty and maximal bending stress. A fuzzy matter element model of optimizing selection of bridge rafts was built up by combining quantitative analysis with qualitative analysis. The method of combination weighting was used to calculate the value of weights index to reduce the subjective randomness. The sequence of schemes and the optimization resuh were gained finally based on euclid approach degree. The application result shows that it is simple and practical.

THE SCENERY FLOW FOR GEOMETRIC STRUCTURES ON THE TORUS: THE LINEAR SETTING

The authOrs define the scenery flow of the torus. The flow space is the union of all flat 2- dimensional tori of area 1 with a marked direction (or equivalently the union of all tori with a quadratic differential of norm 1). This is a 5-dimensional space, and the flow acts by following individual points under an extremal deformation of the quadratic differential. The authors define associated horocycle and translation flows; the latter preserve each torus and are the horizontal and vertical flows of the corresponding quadratic differential. The scenery flow projects to the geodesic flow on the modular surface, and admits, for each orientation preserving hyperbolic toral automorphism, an invariant 3-dimensional subset on which it is the suspension flow of that map. The authors first give a simple algebraic definition in terms of the group of affine maps of the plane, and prove that the flow is Anosov. They give an explicit formula for the first-return map of the flow on convenient cross-sections. Then, in the main part of the paper, the authors give several different models for the flow and its cross-sections, in terms of : stacking and rescaling periodic tilings of the plane; symbolic dynamics: the natural extension of the recoding of Sturmian sequences, or the S-adic system generated by two substitutions; zooming and subdividing quasi-periodic tilings of the real line, or aperiodic quasicrystals of minimal complexity; the natural extension of two-dimensional continued fractions; induction on exchanges of three intervals; rescaling on pairs of transverse measure foliations on the torus, or the Teichmuller flow on the twice-punctured torus.

Effect of tuina exercise on simple obesity in college students

Objective:To observe the effect of tuina exercise on simple obesity in college students.Methods:Fifty-seven college students with simple obesity were divided into two groups according to the stratified randomization method.Twenty-eight in the tuina exercise group were trained in tuina exercise;while 29 in the auricular acupoint sticking group were treated with acuricular acupoint sticking.The tuina exercise group was trained once every other day,and 10 times made one course.The auricular acupoint sticking was replaced once every 4 d,and 5 times made one course.After 2-course treatment,the total therapeutic effect,weight,body mass index (BMI),waist and hip circumferences,serum total cholesterol (TC),triglyceride (TG),high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) were assessed.Results:The total therapeutic effect was 86.2% in the auricular acupoint sticking group and 85.7% in the tuina exercise group.There was no significant difference between the two groups (P>0.05).After treatment,the weight,BMI,waist and hip circumferences were decreased and the differences were statistically significant (all P<0.05).The waist and hip circumferences in the tuina exercise group were lower than those in the auricular acupoint sticking group,showing statistically significant differences (all P<0.05).After treatment,there were no significant intra-group differences in TC,TG,HDL-C and LDL-C in the two groups (all P>0.05),and the between-group differences were not significant (all P>0.05).Conclusion:Tuina exercise has reliable effect in treating obesity.It can produce more significant improvements in waist and hip circumferences than auricular acupoint sticking.But no obvious effect is shown in blood lipid indicators.

Effect of Point Sticking Therapy on Biochemical Markers and Rating of Perceived Exertion in Athletes with Exercise-induced Fatigue

Objective： To observe the effect of point sticking therapy on biochemical markers and Rating of Perceived Exertion （RPE） in athletes with exercise-induced fatigue. Methods： A total of 35 football players were randomly allocated into a blank group, a control group and an observation group. The athletes in the blank group received no treatment, those in the control group take Xi Yang Shen （Radix Panacis Quinquefolii） orally and those in the observation group were treated by point sticking therapy. The athletes＇ RPE, hemoglobin （Hb）, red blood cell count （RBC）, blood urea nitrogen （BUN） and blood glucose （BG） were recorded every day for analysis. Results： The RPE value in the blank group tends to increase, while that in the treatment and the blank groups tend to increase first but decrease afterwards, and the corresponding RPE value in the observation group was smaller than that in the control group. After treatment, athletes in the blank group showed a decrease in Hb, RBC and BG, but an increase in BUN in the blank group; while athletes in the observation and the control groups showed increases in Hb, RBC and BG, but a decrease in BUN. Conclusion： Point sticking can alleviate clinical symptoms induced by exercise-induced fatigue.

A NOTE ON THE PROPERTIES OF STEIN-RULE AND INEQUALITY RESTRICTED ESTIMATORS WHEN THE REGRESSION MODEL IS OVER-FITTED

This paper considers the effect of an erroneous inclusion of regressors on the risk propertiesof the Stein-rule,positive-part Stein-rule and inequality restricted and pre-test estimators in a linearregression model.The two Stein-rule estimators are considered when extraneous information is availablein the form of a set of multiple equality constraints on the coefficients,while the inequality estimatorsare considered under the case of a single inequality constraint.It is shown that the inclusion ofwrong regressors has only minimal effect on the properties of the Stein-rule and positive-part Stein-ruleestimators,and no effect at all on the inequality restricted and pre-test estimators when there is asingle inequality constraint.

Clinical observation of acupuncture plus acupoint sticking therapy for insomnia and its influence on subjective and objective sleep indicators

Objective To observe the effects of acupoint sticking therapy of different dosages and durations on the subjective and objective sleep indicators in insomnia patients.Methods Ninety-six patients with insomnia due to liver-Qi stagnation and spleen deficiency were divided into a high-dosage 7 d group(25 cases),a high-dosage 14 d group(22 cases),a low-dosage 7 d group(21 cases),and a low-dosage 14 d group(28 cases)using the random numbers generated in a stratified and stage-by-stage manner in combination with the visiting sequence.The four groups all received the same acupuncture treatment,but acupoint sticking therapy varied in dosage and duration.Before and after treatment,the actigraphic readings(total time in bed,total sleep time,sleep efficiency,number of wake bouts,length of wakes after asleep,and sleep latency),Pittsburgh sleep quality index(PSQI)score,and symptoms score of traditional Chinese medicine(TCM)were observed.A correlation analysis was conducted among the subjective and objective indicators.Results The PSQI score was positively correlated with the total time in bed and total sleep time(P<0.05).After treatment,the sleep latency,PSQI scores,and TCM symptoms scores changed significantly in the four groups(P<0.05).The total sleep time and sleep efficiency gained improvements after treatment in the high-dosage 14 d and low-dosage 14 d groups(P<0.05).The high-dosage acupoint sticking groups had longer total sleep time compared with the low-dosage groups of the same treatment duration(P<0.05).After treatment,the length of wakes after asleep,PSQI scores,and TCM symptoms scores were better in the 14 d groups than in the 7 d groups of the same acupoint sticking dosage(P<0.05).Conclusion Given the same acupuncture treatment,acupoint sticking therapy of different treatment durations produces different effects on the length of wakes after asleep,PSQI score,and TCM symptoms score in insomnia patients,and the 14-day acupoint sticking treatment is superior to the 7-day treatment.
