To the memory of William Ronald Sendall Sternaspid polychaetes are common and often abundant in soft bottoms in the world oceans. Some authors suggest that only one species should be recognized, whereas others regard a few species as widely distributed in many seas and variable depths from the low intertidal to about 4400 m. There are some problems with species delineation and the distinctive v...

Windows CE 3.0, also known as Pocket PC for palm-sized devices, is becoming increasingly popular among professionals and corporate enterprises. It is estimated that by 2004 Windows CE will have a share of 40% of the marketplace for palm-sized devices. The documented vulnerabilities against a major competitor of WinCE, Palm, and the proliferation of palm-sized devices highlight the need for secu...

Digital libraries have great potential to improve the educational experience. There are a wide variety of such repositories, especially those that focus specifically on education. However, a survey of existing work shows relatively few that have both a narrow subject focus and ample affordances for content browsing. We present our prototype design and implementation for the HumanCentered Comput...

Deep drawing of two-layer sheet is a suitable way to achieve product with a desired shape and desired properties in sheet metal forming technology. Control of deep drawing parameter such as thinning is the most important challenge in this process. The most difficult part of this challenge is differences in material properties and geometry of each layer. In this paper, numerical approach has bee...

An enhanced unfolding Inverse Finite Element Method (IFEM) has been used together with an extended strain-based forming limit diagram (EFLD) to develop a fast and reliable approach to predict the feasibility of the deep drawing process of a part and determining where the failure or defects can occur. In the developed unfolding IFEM, the meshed part is properly fold out on the flat sheet and tre...

The effects of input parameters on the square-cup deep-drawing process for a two-layer aluminum/steel laminated sheet were investigated. Each layer was 0.7 mm thick, and the input parameters covered in the investigation were punch nose radius (PR), die shoulder radius (DR), the clearance between a punch and die (CPD), blank holder force (BHF), and layer arrangement (LA). The effects of the inpu...

In the procedure of Van Handel and Zilversmit (1), triglycerides are measured by assay of glycerol, after removal of phospholipids. Some modifications of this method are given. Zeolite is ground to 80 mesh (2); the unsaponifiedvalues are replaced by a simple reagent blank; oils are purified before being usedas standards. Eight separate extractions from a single serum specimen, assayed in quadru...

Deep drawing is the process of obtaining three-dimensional containers certain depths and shapes under pressing forces with help molds sheet materials. In this study, numerical shaping rectangular cups in angled deep dies was investigated experimentally by using finite element method (FEM). For purpose, die/blank holder surfaces have α=0°, α=3°, α=6°, α=9°, α=12° α=15° angles order to facilitate...

Spiml cord The spinal cord of the spider monkey has 37 segments consisting of eight cervical, thirteen thoracic, five lumbar, three sacral, and eight tcaudal segments. The number of oervical segments is always eight, but there is a considerable variation in the number of thoracic segments, depending upon the number of rib-bearing or thoracic vertebrae. Of ten specimens examined, six have been f...
