The work describes the application of hot gas powder sintering using robotic positioning system with special equipment, designed for this new way of manufacturing technology. Material used for this type of sintering is recycled dust portion of PET plastics, which proposes potential possibility of costs reduction for this kind of production technology, which is focused on the use unusable materials. This opens new potential trends in robotics application, even in a new technology, suitable for rapid prototyping in mechanical engineering. It is sintering of the plastics powder using hot gas, usually nitrogen or any inert gas, to propose the best material structure without any deformation.

Teknlologi ADSB is a new technology in the observation plane which is a combination of global positioning system (GPS), so that the aircraft can be traced to the position, velocity, wind direction, and altitude. This tool can be installed in the aircraft or ground stations and more superior than the radar.ADS-B is indeed a revolutionary look, start with only the antenna and the tool less than for a small refrigerator can detect aircraft and air traffic displays.Automatic Dependent Surveillance- Broadcast (ADS-B) is a detection technology where each plane passing owned transponder emits every two times per second information altitude, position, speed, direction, and other information to ground stations and other aircraft. This information is obtained from the information the Global Positioning System (GPS) or backup Flight Management System (FMS) in each plane. Teknlologi ADSB adalah teknologi baru dalam pengamatan pesawat terbang yang merupakan kombinasi global positioning system (GPS), sehingga pesawat bisa terlacak posisi, kecepatan, arah angin, dan ketinggian. Alat ini bisa dipasang di pesawat atau stasiun darat dan lebih unggul dari radar. ADS-B ini memang terlihat revolusioner, dengan hanya berbekal antenna dan alat kurang dari sebesar lemari es kecil dapat mendeteksi pesawat terbang dan menampilkan lalu lintas udara.Automatic Dependent Surveillance- Broadcast (ADS-B) adalah teknologi pendeteksi dimana setiap pesawat lewat transponder yang dimiliki memancarkan setiap dua kali dalam tiap detik informasi ketinggian, posisi, kecepatan, arah, dan informasi lainnya ke stasiun darat dan pesawat lainnya. Informasi ini didapat dari informasi Global Positioning System (GPS) atau backup Flight Management System (FMS) yang ada di pesawat masing-masing.

In any precision manufacturing process, positioning systems play a very important role in achieving a quality product. As a new approach to current systems, camera-LCD positioning systems are a new technology that can provide substantial improvements enabling better accuracy and repeatability. However, in order to provide stability to the system a global positioning system is required. This paper presents an improvement of a positioning system based on the treatment of images on an LCD in which a new algorithm with absolute reference has been implemented. The method is based on basic geometry and linear algebra applied to computer vision. The algorithm determines the spiral center using an image taken at any point. Consequently, the system constantly knows its position and does not lose its reference. Several modifications of the algorithm are proposed and compared. The simulation and test of the algorithm provide an important improvement in the reliability and stability of the positioning system providing errors of microns for the calculation of the global position used by the algorithm.

A brief summary of some highlights in the study of high energy astrophysical sources over the past decade is presented. It is argued that the great progress that has been made derives largely from the application of new technology to observation throughout all of the electromagnetic and other spectra and that, on this basis, the next decade should be even more exciting. However, it is imperative to observe cosmic sources throughout these spectra in order to obtain a full understanding of their properties. In addition, it is necessary to learn the universal laws that govern the macroscopic and the microscopic behavior of cosmic plasma over a great range of physical conditions by combining observations of different classes of source. These two injunctions are illustrated by discussions of cosmology, hot gas, supernova remnants and explosions, neutron stars, black holes and ultrarelativistic outflows. New interpreations of the acceleration of Galactic cosmic rays, the cooling of hot gas in rich clusters and the nature of ultrarelativistic outflows are outlined. The new frontiers of VHE γ-ray astronomy, low frequency radio astronomy, neutrino astronomy, UHE cosmic ray physics and gravitational wave astronomy are especially promising.

Disruptive luxury is a recent addition to the lexicon of luxury. Understood as both a practical and philosophical antidote to luxury’s entrenched patterns of production and consumption, the term disruptive is proving to be as indeterminate as the word luxury itself, with its complex historical and cultural formations. This article will briefly explore some of the possible meanings of disruptive luxury, before focusing on new technology, especially rapid prototyping or 3-D printing, as a possible route to luxury’s disruption. Utilizing a fashion spread from American Vogue of 1977 to bring into focus the traditional alliance between the luxury trades and new technology, the article will then explore the cultural, economic, and aesthetic similarities between the current “gilded age” of luxury consumption and the art nouveau designers and clientele of the belle epoque and ask whether established luxury will even notice, let alone “feel the force” of, the disruption.

The present paper approaches the issue of using the new technology of Rapid Prototyping [1,2] in product engineering and tries to demonstrate its economic efficiency from the point of view of costs, in comparison with other technologies [. The comparison is made between Rapid Prototyping and plastic material injection. Rapid Prototyping is used for obtaining some prototypes but it also can be successfully used for individual or small series production. The background of the work briefly presented in this paper is related to some experimental research developed by the author regarding Rapid Prototyping Technologies for certain products which are belt pulleys. After the products have been physically created using Rapid Prototyping Technologies, the author was interested in quantifying its economic efficiency. The belt pulley the present paper refers to was obtained by using the Rapid Prototyping Technology FDM (Fused Deposition Modeling [).The working principle of this technology is briefly described later in this paper. As a novelty, the present paper is aiming at determining a criterion that allows a company to choose between the two technologies mentioned above.

In the current time, mastering the rapid prototyping technology and equipments is a complicated question in Vietnam because of shorting of ability and finance for investment. In order to save currency from imported machine, the demand of research and mastering the new technology of rapid prototype machine, especially a program of control motion in Selected Laser Sintering (SLS) rapid prototype machine, is essential in our country in the purpose of manufacture a domestic SLS rapid prototype machine. This paper presents the design of a control program for the SLS rapid prototyping machine that is corporated to the hardward of our typical manufactured SLS machine in our laboratory. From the result of empiriments we considered that the performed program of control motion responded all the requirements of control as well as experimental adjustments of the technological parameters in our manufactured SLS machine. The results of testing the program via manufacture model products by SLS rapid prototyping machine are accepted.
