The factors that contribute to a good design are difficult to be defined and even harder to control, because of the many variables involved such as experience, education, creativity, analytical approach competence, etc.
Defining the product is one of the most important factors to be taken into consideration.
One of the key factors necessary for a robust design process is well structured product definition [3].
The simulation tool estimates the quality of mechanical proprieties and appearance of the resulting part.
Also the defect can be moved in an area where it does not affect the aesthetics of the part (Fig. 17 b).

The advantage and disadvantage of both methods are described and analysed according to the different material property and requirement.
In addition, the sintering process is a key factor to obtain the high dense part with no crack occurrence and desirable microstructure.
A viscometer (DV-III, ULTRA) is used to measure the viscosity because the particle size affects the viscosity of slurry and the fluidity during casting a layer.
This combination gives the material its corrosion-resistance properties.
Green bodies of dental crown and spur gear are fabricated successfully but the optimization of slurry content to manage of shrinkage and sintering parameters are the main factors to obtain the high precision high dense part.

Factors such as humidity and the presence of hard particles in the air can influence the tribological processes and indirectly affect the braking effectiveness.
These difficult to control factors, i.e. hard particles and water, are often present and represent the serious tribological problems during braking operation [4].
The transfer film mediates the interaction between the mating surfaces and changes the tribological properties at the sliding interface significantly [9].

The lamps not only
beautify the shape of automotive and fulfill automotive streamline design, but also are important
factors for automotive running without accidents, especially in night or bad weather.
During the using process, the lamps have fogging and deformation problems, and these problems not only affect the beauty of the lamps, but also seriously influence normal lamp function.
Hao at al [1] give the discussion for the front steering lamp, and Wagner at al. [2] analyzed the effects of different analysis parameters and finite-element types on the thermo-mechanical properties.
Obviously, it means that direct heat radiation is the main factor, which affects the temperature of the lamp in this first stage.

Introduction
Materials that possess both magnetic and electrical properties have drawn much attention in recent years because of their potential use in novel devices in which magnetic and electric properties can be mutually controlled [1].
The TEM specimens were prepared from the polycrystalline samples by mechanical grinding, dimple grinding, and subsequently ion-milling.
Obviously, this is benefit to the improvement in the dielectric properties, as proved by the data of dielectric properties.
To further reduce the dielectric losses of the 0.33BTO-0.67BFO solid solutions and to confirm that the change in dielectric properties is repeatable, the dielectric properties of the samples with higher Mn-doped concentrations (e.g., x = 1.0 - 10) have been measured.

The polarisation resistance of a cathode can be affected by two factors: its porosity and the formation of a secondary phase [9].
The same factors affect the fabrication of dual composite cathodes.
Traditional preparation methods, such as mechanical mixing, limit the preparation of dual composite cathodes.
This synthesis requires three factors in the selection: 1.

Improvement of mechanical, thermal and other properties has to be achieved, where they are dominantly determined by its microstructure [4].
It has excellent castability, sound room temperature (RT) mechanical properties and low cost [5].
It is well accepted that a fine grain size generally results in an increase in mechanical properties, such as yield strength, toughness and ductility, for most metals and alloys [6].
Furthermore, since magnesium has a large Taylor factor due to the lack of slip systems [7], grain refinement is believed to be a good method for improving strength [8].
In this study, it was also found that the grain refinement on AZ91 magnesium alloy was drastically affected by the use of 0.4 wt% strontium.

Because of these and other outstanding material
properties, diamond potentially enables the development of high-voltage and high
frequency electronic devices with superior performance.
The high field electrical transport properties, in particular the breakdown field strength, ultimately determine the upper voltage limit for high voltage devices.
Similarly, the high-field transport properties determine the upper cut-off frequency in high-frequency field effect transistors.
