Spatial Dimensions

When the size of a semiconductor is reduced by an appropriate materials processing technique to a dimension less than about twice the radius of an exciton in the bulk crystal, the band like structure of the semiconductor gives way to discrete molecular orbital electronic states. Clusters of semiconductors in a size regime lower than 2R {where R is the exciton Bohr radius; e.g. 3 nm for CdS and 7.3 nm for CdTe) are called Quantum Dots (QD) because they confine optically excited electron- hole pairs (excitons) in all three spatial dimensions. Structures based on QD are of great interest because of fast response times and non-linearity in optical switching applications.In this paper we report the first HREM analysis of the size and structure of CdTe and CdS QD formed by precipitation from a modified borosilicate glass matrix. The glass melts were quenched by pouring on brass plates, and then annealed to relieve internal stresses. QD precipitate particles were formed during subsequent "striking" heat treatments above the glass crystallization temperature, which was determined by differential thermal analysis.

Banyan Networks

Vertically stacked optical banyan (VSOB) networks are attractive for serving as optical switching systems due to the desirable properties (such as the small depth and self-routing capability) of banyan network structures. Although banyan-type networks result in severe blocking and crosstalk, both these problems can be minimized by using sufficient number of banyan planes in the VSOB network structure. The number of banyan planes is minimum for rearrangeably nonblocking and maximum for strictly nonblocking structure. Both results are available for VSOB networks when there exist no internal link-failures. Since the issue of link-failure is unavoidable, we intend to find the minimum number of planes required to make a VSOB network nonblocking when some links are broken or failed in the structure. This paper presents the approximate number of planes required to make a VSOB networks rearrangeably nonblocking allowing link-failures. We also show an interesting behavior of the  blocking  probability of a faulty VSOB networks that the blocking probability may not  always  increase monotonously with  the  increase  of  link-failures; blocking probability  decreases  for  certain range of  link-failures, and then increases again. We believe that such fluctuating behavior of blocking probability with the increase of link failure probability deserves special attention in switch design.  Keywords: Banyan networks; Blocking probability; Switching networks; Vertical stacking; Link-failures. © 2009 JSR Publications.

The research was conducted during April to June 2012. Primary and secondary data were used in this research. The primary data related to respondent demography and brand equity.   One hundred respondents were selected accidentally around Bengkulu city.  Data were analysed quantitatively and qualitatively.  Quantitative data were processed using Test of Validity, Reliability Test (Hoyt), Cochran Test Analysis, Importance Performance Analysis (IPA), and Brand Switching Matrix Pattern.  The result of the research showed that the NU Green Tea brand is the highest one, and 48% Top of Mind value. Brand Recall in Frestea Green get 45,8%.  Brand Recognition asserts 75% among respondences to the existence of  Joytea brand. The result of Unaware Brand reveals the research doesn’t seem to know Joytea Brand. Analyzing of Branded Association declares that NU Green Tea has 12 brand associations, Frestea Green brand has 10 brand associations, and in other side Joytea Green brand has 7 brand associations which each made brand image. More results for associations Cochran testing, means the consumers aware to the attributes of the product. It’s included that NU Green Tea brand of drinking package has most of the brand image than  Frestea and Joytea Green. Consumer’s perceptions analyzing reveals that NU Green Tea has a good effort as to the respondents want to. Frestea Green must to get more effort to satisfy consumers. At least Joytea Green brand should be awared enough to increase their ability to get more result in consumer satisfying.  Consumers’ loyalty analysis showed that the Frestea brand has good consumers loyalty than NU Green Tea and Joytea Green brand.Keywords: brand equity, ready to drink green tea
