PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA
ABSTRACT This paper is a review of recent trends in United States expenditures on research and development (R&D). Real expenditures by both the government and the private sector increased rapidly between the mid-1970s and the mid-1980s, and have since leveled off. This is true of both overall expenditures and expenditures on basic research, as well as funding of academic research. Preliminary estimates indicate that about $170 billion was...

In 1965, while working at Fairchild Semiconductor, Gordon Moore predicted that the number of transistors in an integrated circuit would double approximately every two years. Moore’s law, as his observation has been dubbed, has so far been the foundation of the business of per- sonal computing and its derivative applications. With its publication in Electronics magazine on April 19‘h, 1965, Moore’s law was introduced...

Laser scanning technology has emerged as a research field in the science and engineering arena. Laser scanning performs a procedure to detect a surface using laser technology. A scanning device analyzes a real-world object to retrieve data on its shape and its appearance. The collected data can then be used to construct a digital three-dimensional model. The aim of the scanning is usually to create a point cloud on an object surface.

SINTERING – METHODS AND PRODUCTS
Sintering refers to the science and technology of production objects from fines or powders. Being a very complex phenomenon, sintering covers a broad subject field and combines chemistry, physics and mechanics. Sintering deals with various material systems such as metals, non-metals, ceramics, polymers, and their combinations. Processes of sintering may occur in a wide temperature range - in a solid state as well as with participation of...

Design patterns have been around for quite a few years. They were originally created by the Gang of Four (Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides), which is responsible for formalizing the accepted design patterns we use today. Their use, while questioned and argued over by different programming schools of thought, has generally been accepted as “best practices” within the development community. The original...

Performance has been an important issue with Java™ since the first version hit the Web years ago. Making those first interpreted programs run fast enough was a huge challenge for many developers. Since then, Java performance has improved enormously, and any Java program can now be made to run fast enough provided you avoid the main performance pitfalls. This book provides all the details a developer needs to performance-tune any type of...
