Central composite design

Introduction Since the management team decided to assess the effective factors on the quality of the welding in the manufacturing process by utilizing simulation, we have to briefly describe the used simulation process called Design of Experiment (DOE) and understand the characteristic of such analytical process. Basically, the process of accumulating the data based on the observations is time-consuming and costly and miscalculation in the return of investment on the improvisation can be harmful to the organization. Therefore, different types of analytical software were developed as alternative tools to assist the companies to examine their hypothesis about the assumed issues on simulated platforms. Using such simulating programs in a Six Sigma process are called Design of Experiments (DOE). DEO is used to detect cause-and-effect relationships and put them in the statistical examination to find the significant parameters in order to take a proper measure to improve the process.…

utilized the DFSS and DOE in order to predict the situation related to stress and to predict the wrap of the specimen by using Design and analysis of computer experiments(DACE). Technology methods like predictive engineering and optimization were used to calibrate the critical parameters…

Knee Wraps: The Benefits and Drawbacks What are knee wraps? The knee wrap is similar to the wrist wrap regarding the logic that applies to both. Knee wraps are also to an “Ace” bandage, except that they are much thicker and stronger. The elastic material that is used to make the knee wrap is the same found in wrist wraps. The allowed width for knee wraps is 8 cm (3 inches), although they can sometimes be 2.0 meter, 2.5 meters or even 3.5 meters long. Advantages of using knee wraps The primary…

and steel is a major to transfer the load to any structure. The decrease in bond strength between the concrete and steel leads to the failure of the structural member. Lap splice of steel is the common connection n to transfer the loads from one steel bar to another to which it is connected. Fiber reinforced polymer is a composite material made of a polymer matrix reinforced with fibers. The fibers are usually glass, carbon, aramid, or basalt. In structural members like a beam, columns and slab…

Egyptian Cotton vs. Bamboo Bed Sheets Egyptian cotton or bamboo bed sheets, which is better? On one hand, Egyptian cotton sheets are well established as the epitome of luxury while bamboo sheets are still fairly new to the world of bedding. On the other hand, bamboo sheets have some unique properties, giving it a competitive edge. So, when you’re shopping for a new set of sheets, should you opt for Egyptian cotton or bamboo? To answer this question, we’ve compared Egyptian cotton to bamboo…

This retrospective study aimed to evaluate the long-term performance of resin based fissure sealants applied in a general dental practice. To do this it set out to evaluate sealant retention and failure rates. This study took place in a general dentistry practice located in the Netherlands. The group studied consisted of regularly attending patients who visited the practice for routine exams during the period from July 2006 until November 2007. Patients that had one or more resin-based sealants…

Virginia Commonwealth State Agency-Northrop Grumman Critical System Outage The commonwealth of Virginia experienced an information technology storage area network outage on August 25th 2010. This affected several agencies and caused 13% of the file servers to fail. The failure mainly impacted the Department of Motor Vehicles and Department of taxation. Because of the outage problem, DMV couldn’t process driver’s licenses and couldn’t share data with other agencies. (1) DMV has been unable to…

2.1 Nanocomposite and nanofiller Composite is the combination of two or more different materials that are mixed together in order to bring out the best properties of both material. A nanocomposite is the composite which exhibit at least one dimension of the nanoparticle size material [17]. The nanoparticle size is mainly used as the disperse particle system to enhance or improve the properties of the composite material such as strength, conductivity and wear resistance. The main reason for…

Aeronautical materials must possess a high Young’s modulus to prevent shape deformation under stress, high resistance to chemical and thermal degradation, high glass transition temperature (Tg), impact strength, amongst numerous others which are more task specific.3 Advancements in polymer chemistry have resulted in a large number of aircraft moving from metallic materials to composite for their primary structures. The definition of a composite states that it is a new material with superior…
