오스트레일리아의 대륙에 처음으로 발을 디딘 사람은 Warramurrungunji라는 여성이다. 그냐는 바다로부터 북오스트레일리아 섬에 나타났고, 내륙으로 향하였으며, 그 과정에서 아이들을 낳고, 각 아이들을 특정 공간에 두었다. 그녀가 들판을 가로질러 이동하며, Warramurrungunji는 각 아이들에게 “나는 너희
(4) Double patterning
The double patterning is divided into four parts, leading with wafer requirements and then two sets of lithographic requirements (Generic Pitch Splitting - Double Patterning Requirements Driven by MPU metal Half-Pitch and Generic Spacer Patterning Requirements - Driven by Flash). The lithography requirements are different for each process; the requirements for pitch splitti
ToolsThe MBE growth can be monitored in real-time using a Reflective High Energy Electron Diffraction (RHEED) system. The system includes an electron gun which directs an electron beam towards the substrate at a shallow angle (1-2°), and a phosphor screen which detects the diffracted beam.
As the substrate surface varies (from rough to smooth) so does the pattern detected at the screen.
direction are by a continuous situation assessment of the changing security climate. Factors that can radically alter the security threat in a particular country or at a particular airport are political agitation or unrest and widespread publicity of other security incidents. Figure 1.2 indicates the conceptual structure of the security planning cycle. Reassessment of threat should take into acco
fatal damage in some aspects as physical, financial, and time. We have called failure.
Let take attention about that how many causes about metal failure and suggestion about them. And we will show the several examples of bolt failures that have been involved in a certain environment. Through this article we can know how to use a bolt in appropriate situation and make a more sustainable bolt.
3D printing
3D printing or additive manufacturing (AM) refers to any of the various processes for printing a three-dimensional object. Primarily additive processes are used, in which successive layers of material are laid down under computer control. These objects can be of almost any shape or geometry, and are produced from a 3D model or other electronic data source.

- 나이지리아의 자동차 산업은 1969년도의 단순조립단계를 거쳐 1970년도부터 1974년까지 정부의 경제개발계획에 의해 2곳의 승용차 조립공장이 건설되는 등 발전을 거듭하였으며 1975년부터 1980년 사이 4곳의 자동차 조립공장이 추가로 건설되는 등 부흥기를 맞은 바 있다. 그러나 80년대
process oriented, using modern techniques to concentrate on one production process, one base raw material and a limited product range. This type of manufacturing optimizes efficiency and production volume. The Danville facility that opened in 2008 specializes in the manufacture of IKEA's LACK, EXPEDIT and BESTA lightweight panel furniture and storage systems. All panels processing and finishing i
process of reverse logistics
This part include the actors and the processes. Reverse logistics actors can be differentiated into returners, receivers and collectors / processors. Any party can be a returner, including customers. Receivers can be found in the whole supply chain, hence suppliers, manufacturers, wholesalers, retailers. Next there is a group of actors

Airport management, in common with others involved in the operation of elements of the civil air transportation system, are required to take measures that will provide a high level of protection of buildings and equipment (including aircraft), in addition to ensuring the safety and personal security of passengers and staff using the system. This must be done in manner that disturbs the normal ope
