in this study, the disadvantages of wood, which is widely employed in producing music instruments, are discussed. for example, high moisture sensitivity, low impact resistance, and time-consuming procedure as well as various properties of different species or in several parts of one specimen which are the main problems of wooden music instruments are extensively discussed in this paper. many ma...

The Hotelling's  control chart, is the most widely used multivariate procedure for monitoring  two or more related quality characteristics, but it’s power lacks the desired performance in detecting small to moderate shifts. Recently, the variable sampling intervals (VSI) control scheme in which the length of successive sampling intervals is determined upon the preceding values has been proved t...

In coping with the trend toward the much higher powered electric-motor driven injection molding machine, multi-AC servomotors control system has become necessary in order to control the molding machine mechanism. Thus, it is inevitable to use a synchronous positioning control technique not to cause the excessive mechanical stress in the machine body. It is possible to realize the synchronous po...

Objectives: This In-vitro study was designed to compare the Impact strength and Residual monomer content of conventional and high impact types of denture base resins polymerized by Compression and Injection molding technique with short curing cycle. Materials and Methods: Forty samples were made (twenty from each technique)in the dimension of 60 × 10 × 3 with 2 mm notch on the thickness side. T...

Design flexibility, mass customization, waste reduction and the ability to manufacture near-net complex-shape structures, as well rapid prototyping, are main advantages of Metal Injection Molding (MIM). A brief review MIM technique, materials their development trending applications using iron powders was delineated. The ground-breaking in automotive, medical, magnetic were discussed. current-st...

Injection molding technology should assure a high level of quality control of the molded parts in an automated way. Inherent complexities of the process make mathematical modeling di¢cult, hindering the control quality demands of conventional methods. Neural networks adaptive data based technology has been successfully applied in industrial applications since these rely on highly nonlinear mode...
