School of Public Administration, Hebei University of amp;apos;Economics and Business, Shijiazhuang, Hebei, 050061, China Abstract: This paper discusses the chief techniques and design principles of an ultra-high speed and dual-channel data acquisition card based on PXI bus, using FPGA (Field Programmable Gate Array) as logic controller cell. The instrument consists of pre-pro- cess ciruit, A/D converter, SDRAM (Synchronous Dynamic random access memory), and control circuit integrated in FPGA. It can achieve allowing up to 1000MHz rea-time sampling rate. The test result indicates that the system works normally and the system design is sucessul.

Influence of dopidynamic priority basedicro structure and tribological properties of plasma sprayed 3Al2O3–2SiO2 coating A b s t r a c t With the combination of self-lubricating ability and mechanical property, high-performance ceramic-graphite composite coatings are potential candidates for machine components. Mullite/nickel cladded graphite (Ni–graphite) composite coatings with different content of graphite were fabricated by air plasma spraying technique. Results show that doping a suitable amount of Ni–graphite could greatly reduce the defects of mullite coating without significant decrease of their hardness. With the formation of re-graphitization lubricating film on friction surface, the friction coefficient of composite coating with 20 wt% Ni–graphite was observed to be 0.28, which was approximately 52% lower than that of pure mullite coating, and its wear rates was 4.15 times lower than that of pure mullite coating. Introduction Plasma spraying

Operation Mode and Development Countermeasures of Import Cross-border E-commerce Logistics in China Abstract. With the increasing demand of domestic consumers for foreign high-quality products, and the increasing government support for import cross-border e-commerce,import cross-border e-commerce has developed rapidly in China. Import cross-border logistics, which has been accompanied by the development of imported cross-border e-commerce, has also made considerable progress. Through the analysis of the driving forces of the development of import cross-border e-commerce, we can understand the reasons for the rapid development of import cross-border e-commerce. At the same time, the paper analyzes the development status of import cross-border e-commerce logistics, and studies three operation modes of import cross-border e-commerce logistics: general trade import mode, direct mail import mode and bonded stock import mode. It also puts forward countermeasures for the development of

THE WORK OF ART The work of art is an object as well as a historical event. To describe and analyze it we use categories and vocabularies that have become more or less standard and that are indispensable for understanding this book. General Concepts Form, for the purposes of art history, refers to the shape of whatever is the object of art; in the made object it is the shape that the expression of content takes. To create forms, to make a work of art, artists must of course shape materials with tools. Of the many materials, tools, and processes available, each has its own potentialities and limitations, and it is part of the artists creative activity to select the ones most suitable to their purpose .The technical processes they employ as well as the distinctive, personal way they handle them, we call their technique. If the material artists use is the substance form. Form, technique , and material are interrelated ,as can be readily seen in a comparison of the marble st

Appreciation of American Classic Movies The Godfather Background Information A brief introduction to the history of Mafia in New York Although the exact origin of the word “ mafia ” is uncertain , some believe it originated in 1282 during the French invasion of Sicily and the saying , “ Morte Alla Francia Italia Anela ” (Death to the French is Italyrsquo;s Cry) , or MAFIA . Then , eventually the word “ mafia ” , in Sicily. Another theory of the origin of “ mafia ” begins as early as the 9th century . During that period , Sicily was ruled by Arab forces . The original inhabitants were oppressed , and desperately tried to escape and find refuge . In Arabic , the word “ mafia ” means “ refuge ” . Sicily was invaded by the Normans in the 11th century and its people were forced into labor and oppression once again . Every invasion of Sicily , thereafter , ( French invasion in the 12th century , Spanish in the 13th century , then Germans , Austr

Graphics Communication an Appraisal of an Art of Learning in Contemporary Nigerian Education Emmanuel Bankole Oladumiyte Department of Industrial Design, School of Environmental Technology, Federal University of Technology, Akure, Nigeria Received 15 May 2014; revised 17 June 2014; accepted 25 July 2014 Copyright copy; 2014 by author and Scientific Research Publishing Inc. This work is licensed under the Creative Commons Attribution International License (CC BY). Abstract The concept of communication graphics is characterized by the technology that is infused with information and communication technology which cover any product that stores, retrieves, manipulates, transmits or receive information that helps in disseminating knowledge through graphic device visuals. That generates interest which is the key note to instruction, motivation, stimulation and ultimate finding relevance through the provision of changing experiences in knowledge disseminating. It

Shooting video techniques Speaking of DV video shooting skills, the basic technique also is 'pan'. But due to the characteristics of DC itself, even the DV shooting traditional push-pull pan, also because of the characteristics of DC itself and change of operation. DV shooting exquisite push-pull pan, but we are here to shake and move on the front, why? Because a lot of digital camera when shooting video, is not 'push' and 'pull', in this case, the 'push' and 'pull' can be replaced by 'move', so, when using a digital camera for video shooting, one of the most common technique is to 'move'. 1, push Push the lens, is the camera 'push' forward, the sense that gives a person is the picture frame to move forward, that is close to in the direction of the subject. By pushing the lens, our viewpoints move forward gradually, the subject from small to large, and the surrounding environment is from big to small. However, we always guarantee the best subject is in the middle of the

Animation Animation is the rapid display of a sequence of images of 2-D or 3-D artwork or model positions to create an illusion of movement. The effect is an optical illusion of motion due to the phenomenon of persistence of vision, and can be created and demonstrated in several ways. The most common method of presenting animation is as a motion picture or video program, although there are other methods. Early examples An Egyptian burial chamber mural, approximately 4000 years old, showing wrestlers in action. Even though this may appear similar to a series of animation drawings, there was no way of viewing the images in motion. It does, however, indicate the artists intention of depicting motion. Early examples of attempts to capture the phenomenon of motion drawing can be found in paleolithic cave paintings, where animals are depicted with multiple legs in superimposed positions, clearly attempting to convey the perception of motion. in Iran Five images sequence fr
