NURBS 곡면기법을 이용한 압출금형 곡면의 표현방법에 관한 연구

In the present study, an advanced surface construction method based on NURBS surface scheme is proposed to construct the extrusion die surface. The inlet and outlet profiles we precisely described with NURBS curves using the cubic appropriate control points and weights. The interior control Points of surface are generated using the cubic interpolation of the weights at the inlet and outlet sections. In order to verify of the proposed method, automatic surface generation is carried out for the various types of extrusion die surface.

6 Vpp - 66 GHz-ultrabroadband amplifier for fibre-opticaltransmission systems

A large amount of bandwidth has been achieved with advanced construction methods developed for ultra-high bandwidth distributed amplifiers. A 66 GHz-bandwidth GaAs device with more than 6 Vpp of voltage swing has been manufactured.

Do-it-yourself TMN applications by visual programming methods

The development of specialized telecommunications management network (TMN) applications using conventional programming languages requires enormous development resources. In this article a method is presented that enables any network operator to create customized applications utilizing visual programming techniques. The advanced script construction method outlined in this article represents a script in the operations system (OS) as a linked network of templates for individual network element (NE) commands/Q3 operations and NE responses similar to a hypertext structure employed for the navigation through multimedia documents. The scripts are created by using visual programming techniques. The craft can interactively influence script control flow during its execution. This creates a vast number of options for script construction and virtually eliminates the expensive design and development of specialized TMN applications. >

A Challenge for Research

Over the years, contractors have looked to educational institutions to provide a cadre of skilled construction employees, and to gain access to new construction technologies. Early contractor proponents of construction education considered research to be a necessary educational component of benefit to the contracting community. It now appears that this research objective has been over‐looked and that communication has been lost between contractors and the researchers. The present work attempts to show that the research community, needs the construction industry if construction programs are to survive in the major universities, and that nonengineering construction education programs also need research to provide the teaching personnel and the subject matter for educating students. The construction industry needs research to develop the advanced construction methods and management skills needed to meet competition and increase profits. The research community is asked to expend greater efforts in developing mutual relationships with contractors and technology oriented educational programs. The Construction Research Council (CRC) is proposed as a possible leader in these efforts.
