At first step polymer optical fibers (POFs) are used in short distance for optical data transmissions. At second step SiO2 nanoparticles were prepared by sonochemical-assisted method. Silica nanoparticles were added to polymer matrix to prepare polymer based nanocomposites. Most of the POF applications are in the medical and electrical devices. There are several methods for fabrication of POFs,...

Many modern industrial processes are capable of generating rich and complex data records that do not readily permit the use of traditional statistical process control techniques. For example, a “single observation” from a process might consist of n pairs of (x, y) data that can be described as y = f(x) when the process is in-control. Such data structures or relationships between y and x have be...

We outline a new approach to process modeling in support of development of product data models. It is based on the definition of process models with far greater detail than have been used previously, and on the automated mapping of these models to product model schemas. A new process-modeling tool was developed for this purpose along with applications for structuring and analyzing the data coll...

In parametric IC testing, outlier detection is applied to filter out potential unreliable devices. Most outlier detection methods are used in an offline setting and hence are not applicable to Final Test, where immediate pass/fail decisions are required. Therefore, we developed a new bivariate online outlier detection method that is applicable to Final Test without making assumptions about a sp...

This paper is a qualitative case study analysis of the issues involved in designing and implementing data sculptures, the physical “embodiment” of data in a tangible presence, shape or form, within the context of an undergraduate design studio. It demonstrates how approaches and theories from the field of data visualization can form a rich contextual resource and motivational tool for teaching ...

Since the early 1990s, organizations have focused on making smarter decisions in their integrated supply chain central planning, but the representation of capacity and cycle time has remained static and linear in contrast to its complex nature. This includes central planning for firms with semiconductor fabrication facilities (FABS) as a component of a complex demand supply network(DSN) where m...

Collagen I hydrogels are commonly used to mimic the extracellular matrix (ECM) for tissue engineering applications. However, the ability to design collagen I hydrogels similar to the properties of physiological tissues has been elusive. This is primarily due to the lack of quantitative correlations between multiple fabrication parameters and resulting material properties. This study aims to ena...

a simple method for fabrication of highly ordered gold nanorod film is introduced in this article. the procedure is based on thermal evaporation of gold into a porous anodic alumina film (paa). the ppa film was fabricated by combining the hard and mild anodization. this combination effectively decreases the processing time of fabrication of highly ordered porous anodic alumina film with control...

Due-date performance is one of the most important production indexes for success utilized by wafer fabrication factories. Traditionally, the industry sets a specific due-date tightness level and a dispatching rule based on the total processing time, the production capacity, pre-defined order release criteria and historical data, to ensure deliveries are made on-time. However, such policies typi...

With today’s keen competition, semiconductor market has changed from producer-oriented to customer-oriented. To be successful, companies need to consider both customer satisfaction in demand and the ultimate profit goal of companies. Semiconductor fabricators today must face an environment with multi-product types and multi-priority orders. Since semiconductor fabrication has a very complicated...
