Hu Yong,Xiang Mingjun,Qiu Xing,Song Pengfei,Song Jingan,Peng Fuhua 대한기계학회 2014 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.28 No.8

Gear hobs are widely used to machine involute gears. However, using Archimedes worm as a base worm of the gear hob, which iscommon used in industry, leads to the generating of theoretical error of the gears. Even though this error can be eliminated by using theaccurate involute base worm or be greatly reduced by complicated modification of the shape of cutting edges, the manufacturing cost isvery high. Reported in this paper is an improved design of inserted tooth finishing hob for involute gears on a conventional hobbing machineaiming to eliminate this error in an economical way. For that purpose, both descriptive-geometry-based method and mathematicalanalyzing are employed to illustrate the major parameters of the base worm and the formation and parameters of the inserted tooth finishinghob. In addition, an approximating formation of the flank for the convenience of grinding the inserted tooth finishing hob is proposedand the errors that this substitution arc surface is discussed. Ultimately, the other advantages of this inserted finishing hob are demonstrated.

Stabilization of Discrete-Time Networked Control Systems with Partly Known Transmission Delay: A New Augmentation Approach

Song-Lin Hu,Jin-Liang Liu,Zhao-Ping Du 제어·로봇·시스템학회 2011 International Journal of Control, Automation, and Vol.9 No.6

This paper is concerned with the stabilization problem of discrete-time networked control systems with partly known transmission delay. Considering the random property of the networked-induced delay, the original system is transformed into a new delay model with stochastic parameter matrices by introducing a novel state augmentation technique. Based on the new model, a new delay-distribution-dependent criterion for the mean square stability of the closed-loop system is derived by using the Lyapunov-Krasovskii functional approach and linear matrix inequality technique. The solvability of the derived criterion depends on not only the size of the delay, but also the probability distribution of the delay taking value in a finite set. Finally, two numerical examples are given to demonstrate the effectiveness of the proposed method.

Continuous-Current Mode Operation of a Semi-Dual-Bridge Resonant Converter

Song Hu,Ming Lu,Xiaodong Li 전력전자학회 2015 ICPE(ISPE)논문집 Vol.2015 No.6

Originated from the dual-bridge resonant converter, a semi-dual-bridge resonant converter is proposed for unidirectional applications in this paper. The single phase-shift modulation is adopted for power regulation. It is proved that the proposed converter is capable to work in either continuous-current mode or discontinuous-current mode. Compared with the dual-bridge resonant converter with single phase-shift modulation, the high circulation energy in output bridge is eliminated and the zero-voltage switching range of all switches is extended in the proposed converter. Steady-state analysis of the converter in continuous-current mode is performed using fundamental harmonics approximation. A design example based on the analysis results is presented and then verified through both simulation and experimental test on a lab prototype converter.

QTL Analysis of Floral Traits of Rice (Oryza Sativa L.) under Well-Watered and Drought Stress Conditions

Song Ping Hu,Ying Zhou,Lin Zhang,Xu Dong Zhu,Zheng Gong Wang,Lin Li,Li Jun Luo,Qing Ming Zhou 한국유전학회 2009 Genes & Genomics Vol.31 No.2

Three floral traits, spikelet number per panicle (SNP), percentage of single exserted stigma (PSES) and dual exserted stigma (PDES) of a RI population with 185 lines under water stress and non-stress conditions for two years were investigated in a drought tolerance screening facility. ANOVA results showed high significance between years, lines, and water stress treatments, together with interactions among them in pairs. High phenotypic correlation was found between PSES and PDES (r=0.5424***). Based on a linkage map of 203 SSR markers, when under well-watered condition, six QTLs (qSNP-3b, qSNP-4, qSNP-11 qSNP-2, qSNP-5 and qSNP-9) were detected for SNP. Half of them had significant Q×E interactions. Three QTLs (qPSES-1, qPSES-2, qPSES-5) were found to influence PSES, including one locus (qPSES-2) having Q×E interaction. And three QTLs (qPDES-2, qPDES-5 and qPDES-8) were also detected to influence PDES. qPDES-5 was found to have Q×E interaction. The contribution rate of a single QTL varied from 0.80% to 8.83% for additive effect, and 1.86% to 15.25% for Q×E interactions. Under drought stress, six QTLs (qSNP-3a, qSNP-4, qSNP-7a, qSNP-7b, qSNP-8 and qSNP-9) were associated with SNP, including qSNP-3a and qSNP-4 with Q×E interaction. Three QTLs (qPSES-1, qPSES-10 and qPSES-12) were located on rice chromosome 1, 10 and 12 for PSES. Four QTLs (qPDES-1a, qPDES-1b, qPDES-4 and qPDES-9) were detected for PDES, including qPDES-9 with Q×E interaction. The additive effect of single QTL can only explain 1.16% to 5.84% of total variance while Q×E interaction of four loci can explain 4.25% to 11.54% of total variance for each locus. There were one to nine pairs of epistatic QTLs influencing SNP and stigma exsertion. The contribution rates of additive and epistatic effects seemed to be in a low magnitude for most cases (0.76%~9.92%) while a few QTLs or QTL pairs explained more than 10% of total variance. Some main effect QTL and epistasis were commonly detected among PSES and PDES, explaining the high positive correlation between them. Few QTLs were detected under both water stress and non-stress conditions, indicating that drought had severe impact on the genetic behaviors of both spikelet number and stigma exsertion.

Theoretical analysis of simply supported channel girder bridges

Hong-Song Hu,Jian-Guo Nie,Yu-Hang Wang 국제구조공학회 2015 Structural Engineering and Mechanics, An Int'l Jou Vol.56 No.2

Channel girder bridges that consist of a deck slab and two side beams are good choices for railway bridges and urban rail transit bridges when the vertical clearance beneath the bridge is restricted. In this study, the behavior of simply supported channel girder bridges was theoretical studied based on the theory of elasticity. The accuracy of the theoretical solutions was verified by the finite element analysis. The global bending of the channel girder and the local bending of the deck slab are two contributors to the deformations and stresses of the channel girder. Because of the shear lag effect, the maximum deflection due to the global bending could be amplified by 1.0 to 1.2 times, and the effective width of the deck slab for determining the global bending stresses can be as small as 0.7 of the actual width depending on the width-tospan ratio of the channel girder. The maximum deflection and transversal stress due to the local bending are obtained at the girder ends. For the channel girders with open section side beams, the side beam twist has a negligible effect on the deflections and stresses of the channel girder. Simplified equations were also developed for calculating the maximum deformations and stresses.

N/A Recently, recombinant human erythropoietin (rHu-EPO) has been used to treat various types of anemia. YHB216 is a new rHu-EPO developed by Yuhan Research Institute. In this study, we investigated the single dose and 4-week repeated dose toxicity of YHB216 in Beagle dogs. In the single dose toxicity study, YHB216 was administered intravenously at single dose levels of 0 and 25,000 IU/㎏ to dogs (2 dogs/sex/ group). There were no treatment-related changes in survivals, clinical signs, body weight gain, hematological values, blood chemical values, and necropsy finding during experimental period. In the repeated dose toxicity study, YHB216 was administered intravenously to dogs for 4 weeks at the dose levels of 0, 100, 500, and 2,500 IU/㎏ (3 dogs/sex/group). There were no toxicologically significant changes in clinical signs, body weights, food and water consumptions, ophthalmoscopy, urinalysis and blood chemistry. There were increased values of red blood cell, hemoglobin, and hematocrit at all treated groups. Spleen revealed increased weight and extramedullary hematopoiesis at 500 IU/㎏ or more. These changes are all considered to be pharmacology-related effects and were recovered after 4-week recovery period. From these results, it is concluded that LD_50 value was above 25,000 IU/㎏ in the single dose toxicity study of YHB216 in dogs and the no observed adverse effect level (NOAEL) was 100 IU/㎏/day in the repeated dose toxicity study of YHB216 in dogs.

Background/Aims Patients with long-standing diabetes often demonstrate intestinal dysfunction and abdominal pain. However, the pathophysiology of abdominal pain in diabetic patients remains elusive. The purpose of study was to determine roles of voltage-gated sodium channels in dorsal root ganglion (DRG) in colonic hypersensitivity of rats with diabetes. Methods Diabetic models were induced by a single intraperitoneal injection of streptozotocin (STZ; 65 mg/kg) in adult female rats, while the control rats received citrate buffer only. Behavioral responses to colorectal distention were used to determine colonic sensitivity in rats. Colon projection DRG neurons labeled with DiI were acutely dissociated for measuring excitability and sodium channel currents by whole-cell patch clamp recordings. Western blot analysis was employed to measure the expression of NaV1.7 and NaV1.8 of colon DRGs. Results STZ injection produced a significantly lower distention threshold than control rats in responding to colorectal distention. STZ injection also depolarized the resting membrane potentials, hyperpolarized action potential threshold, decreased rheobase and increased frequency of action potentials evoked by 2 and 3 times rheobase and ramp current stimulation. Furthermore, STZ injection enhanced neuronal sodium current densities of DRG neurons innervating the colon. STZ injection also led to a significant upregulation of NaV1.7 and NaV1.8 expression in colon DRGs compared with age and sex-matched control rats. Conclusions Our results suggest that enhanced neuronal excitability following STZ injection, which may be mediated by upregulation of NaV1.7 and NaV1.8 expression in DRGs, may play an important role in colonic hypersensitivity in rats with diabetes.
