Automatic ball balancers (ABBs) have shown good performance in suppressing vibration in planar eccentric rotors. All relevant studies assume that the plane of the circular track of the balls of ABB needs to be mounted perpendicular to the spindle. However, in practical applications, assembly deviations are always unavoidable. Since no discussion about the deviation angle has been seen, in this paper a new model is established to explore the system of a planar eccentric rotor equipped with a skew-mounted ABB. First, the angular positions of the balls and their restriction conditions when the vibration of the system is completely suppressed are analyzed, and the theory to examine whether the ABB is skew-mounted is obtained. Finally, numerical simulations are performed to verify the theoretical model and to compare the characteristics and differences in suppressing the unbalanced vibration of the system between the conditions of ideal and skewed mounted ABB.

This study presents a machine learning based method for design customization of a 3D respiratory mask. A parametric model of a3D human face was constructed from an anthropometric database consisting of 495 facial models. An AdaBoost.R algorithm wasapplied to identify a set of measurable parameters most related to the facial geometry. The correlation between parameters wasestimated using principal component analysis and linear regression. With those parameter values as input, the parametric modelgenerates 3D meshes of a human face that serve as a design reference for the construction of a customized respiratory mask of agood fit. We conducted a series of experiments with 10-fold cross-validation to validate the effectiveness of the proposed method.
Effect of a Carbon Additive on the TbCu7-type Melt-spun Sm(Co, M)7 (M=Ti, Zr, Hf, V and Ge) Ribbons
Chih-Chieh Hsieh,Shih-Teng Huang,Jin-Sheng Guo,Chih-Wei Shih,Wen-Cheng Chang,Huang-Wei Chang,Chun-Chung Shaw 한국물리학회 2013 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.63 No.3
The effect of a carbon additive on the microstructure and the magnetic properties of melt-spunSmCo7−xMxCy (M=Ti, Zr, Hf, V and Ge; x = 0 - 0.3 and y = 0 - 0.1) ribbons was studied. Based on the XRD and the TEM analyses, a pure 1:7 phase could be formed for the C-containingribbons with M= Ti and Ge. However, carbide phases, i.e., Sm2C3 for M=Zr and Hf, and SmCoC2for M=V, respectively, were found. Nevertheless, a slight C addition may effectively refine themicrostructure and improve both the intrinsic coercvity and the magnetic energy product in all thestudied ribbons. Among them, the SmCo6.9V0.1C0.1 ribbons with r = 58.7 emu/g, iHc = 13.5kOe and (BH)max = 9.3 MGOe, and the SmCo6.9Hf0.1C0.1 ribbons with r = 61.6 emu/g, iHc =11.8 kOe and (BH)max = 10.3 MGOe are most suitable for the bonded magnet applications.

A successful decolorization of methylene blue (MB) was achieved through advanced Fenton’s process(AFP) coupled with sonolysis (sono-AFP) using zero-valent iron (Fe0) aggregate as a catalyst. Thedecolorization was dependent on the pH, Fe0, H2O2 doses, and acoustic power. Fe0 aggregate wasreusable. A modified pseudo-first order equation was developed to describe the decolorization kinetics. To save electricity, short ultrasound irradiation was applied to the system. MB was completely degradedin the sono-AFP under optimized condition. The decolorization was obviously inhibited by the presenceof Cl , but it was unaffected by the presence of H2CO3, H2PO4, ClO4, NO3, and SO42

The steel bars account for a high percentage of material costs for the current construction projects. At the present time, most of the construction projects for the factories of thin-film transistor liquid crystal display (TFT-LCD) complete the transactions of steel bars when the suppliers ship the steel bars to the temporary storage/processing sites. This paper applies the buy-in concept in the Theory of Constraint (TOC) on the supply chain of steel bars. In this study, suppliers are required to establish warehouses at the construction sites and complete the transactions when the formed and processed steel bars are shipped into the factory sites. The aim is to find a win-win solution to meet with the expectations from constructors as they hope that there is no need to build up inventories but supply is ready at any time. Also, this paper compares and analyzes the traditional supply/inventory model of steel bars and the Demand-Pull (D-P) model under the TOC framework. It is proved that Vendor Management Inventory (VMI) in the D-P model is able to more effectively manage steel bars as a material.
