The operation of distribution system with the components in deteriorating condition makes the system reliability worsen. It is important to find the solution for balancing failure cost and maintenance benefits such as down-time and reliability. In this paper, time to replace the components in optimum condition based on constant-interval replacement mode is investigated. The optimal replacement time is mainly depended on components reliability and the cost ration of preventive replacement and failure replacement. In this paper, equipment inspection method and Weibull Analysis is applied to obtain the accurate reliability estimation. Weibull Analysis is applied with constant-interval replacement model to investigate the optimum replacement time for each component considering the different cost ratios. According to the quantitative results, the determination of the optimal replacement time (OPT) can minimize the total downtime and failure cost. Consequently, the reliability of the system is maximized and

TY - JOUR. T1 - Effect of thermocycling on shear bond strength of glass ionomer cements. AU - Ballal, Nidambur Vasudev. AU - Paulson, Liz. AU - Ginjupalli, Kishore. AU - Ozcan, Mutlu. PY - 2019/1/1. Y1 - 2019/1/1. N2 - To evaluate the effect of thermocycling on shear bond strength of Fuji IX glass ionomer cement and a novel glass ionomer cement (Ketac Universal) to dentin. A total of 40 extracted human molars were divided into 4 groups (n = 10). The occlusal surfaces were ground flat to expose dentin using diamond discs. Dentin surfaces were treated according to manufacturers instructions, and restorative materials were applied onto a plastic mold of 3mm height and 4mm diameter. The shear bond strength of Ketac Universal and conventional Fuji IX glass ionomer cements was evaluated after 24 h using Instron Universal Testing Machine at a crosshead speed of 0.5 mm/min before and after the specimens were subjected to thrmocycling. There was no statistical difference in the shear bond strength of ...

This study evaluated the stress distribution based on the canine pillar geometry in human skull, using a finite element analysis. Computed tomography of human skull was used to build a finite element model, which was composed by all bony structures of canine pillar: canine eminence, canine fossa, frontal process of maxilla, glabellum and superciliary arch. A support on the bite contact of maxillary canine tooth and a resultant force of the masticatory muscles was applied in the simulation. Equivalent Von-mises and maximum principal stresses were analyzed along the structures that compose the canine pillar geometry. Von-mises stress presented high stress concentrated at the canine fossa and frontal process of maxilla. Maximum principal stress showed compression areas at the canine fossa and part of frontal process and tensile stress at canine eminence and part of the frontal process. In conclusion, the different stress areas means different force concentrations transmitted along the canine pillar ...

The photoelastic effect (alternatively called the piezo-optical effect) is the change of refractive index caused by stress. Applications of photoelasticity involve applying a given stress state to a model and utilising the induced birefringence of the material to examine the stress distribution within the model. The magnitude and direction of stresses at any point can be determined by examination of the fringe pattern, and related to the studied structure.. Two different types of fringes can be observed in photoelasticity: isochromatic and isoclinic fringes. Isochromatic fringes are lines of constant principal stress difference, (σP - σQ). If the source light is monochromatic these appear as dark and light fringes, whereas with white light illumination coloured fringes are observed. The difference in principal stresses is related to the birefringence and hence the fringe colour through the Stress-Optic Law.. Isoclinic fringes occur whenever either principal stress direction coincides with the ...

Reed and wheat straw particleboards bonded with urea formaldehyde (UF) resin were manufactured from two different material configurations (i.e., fine and coarse particles). The board densities were in the range of 0.550-.90g/cm3. The effects of particle size and board density on the board properties were examined. The properties of particleboard produced from fine particles were better than those made from coarse particles. An increase in board density resulted in a corresponding improvement in the board properties. The properties of OF bonded reed and wheat straw particleboards were relatively lower than those of commercial particleboards. Three silane coupling agents were used to improve the bondability between the reed and wheat particles and OF resin. Results of this study indicate that all the board properties were improved by the addition of silane coupling agent. The degree of improvement achieved from each coupling agent was different; epoxide silane was found to be more effective for reed straw

Materials and Methods: Buccal enamel of 80 bovine teeth was submitted to finishing and polishing with metallographic paper to a refinement of #600, in order to obtain a 5-mm2 flat area. Blocks (2 x 4 x 4 mm) of laboratory composite resin were cemented to enamel according to different protocols: (1) untreated enamel + RelyX Unicem cement (RX group); (2) untreated enamel + Bifix SE cement (BF group); (3) enamel acid etching and application of resin adhesive Single Bond + RelyX Unicem (RXA group); (4) enamel acid etching and application of resin adhesive Solobond M + Bifix SE (BFA group). After 7 days of storage in distillated water at 37°C, the blocks were sectioned for obtaining microbar specimens with an adhesive area of 1 mm2 (n = 120). Specimens were submitted to the microtensile bond strength test at a crosshead speed of 0.5 mm/min. The results (in MPa) were analyzed statistically by ANOVA and Tukeys test ...

Hair rebonding allows breakage of hair bonds, rearranging those bonds and restructures it once again to the desired, straight, state. Using a flat iron, the hair bonds are restructured and then applied with a neutralizing agent that will preserve the newly structured hair bonds.. The tool usedis a flat-iron to flatten/straighten the hair and relatively takes longer than relaxing.. The effect relatively takes longer than relaxing but is more lasting than relaxing and the results of hair rebonding will be a pin-straight, flat-out stick straight hair.. If you like the sleek, super straight look, then this option will be suitable for you. But to me, after many years (and many times!) of rebonding my hair, I find that it looks rather unnatural and closer to a broomstick effect than a healthy straight hair effect. ...

In determining the fracture toughness of a test specimen, standards currently require either locally-measured load-line displacements or clip gage displacements. In order to measure these parameters, secondary sensors generally need to be installed and calibrated, which often comes at a higher cost. As crosshead displacements are automatically measured in most modern material test machines, use of the crosshead measurements alone would be less expensive. Although much criticism exists on the accuracy of this approach in determining CTOD values, the method can still prove sufficiently accurate for many applications. The current paper aims to assess the magnitude of the errors that arise from using the crosshead displacement in fracture mechanics testing of steels with the Single Edge Notched Bending (SENB) specimen geometry. The results show that for steels with sufficiently large toughness, the use of the crosshead displacement to calculate J and convert to CTOD produces results within 10% of ...
