Abstract: Sixth Sense is a wearable gestural interface that augments the physical world around us with digital information and lets us use natural hand gestures to interact with that information. Sixth Sense recognizes the objects around us, displaying information automatically and letting us to access it in any way we need. The Sixth Sense prototype implements several applications that demonstrate the usefulness, viability and flexibility of the system. It allows us to interact with this information via natural hand gestures. This has the potential to become the ultimate "transparent" user interface for accessing information about everything around us. The key here is that Sixth Sense recognizes the objects around you, displaying information automatically and letting you access it in any way you want, in the simplest way possible. We can incorporate to get rid of color markers, camera and projector inside mobile computing device. Whenever we place pendant- style wearable device on table, it should allow us to use the table as multi touch user interface. In this paper, we have presented the technology behind the sixth sense technology and its application and advantage.

Abstract: Indigenous agriculture is base on farmer’s cooperation with nature. Sustainable agriculture that inspired by indigenous systems would rectify most of deficiencies of modern agriculture. Indigenous agriculture systems is production of centuries of cultural and subsistence revolution. These systems are collections of farmer’s experiences that haven't enjoy sources except inputs, capital and indigenous knowledge. And consequently they accessed to such sustainable agriculture that just is dependent on using restricted local resources and existing humane and animal power. At indigenous agriculture, culture diversity and frequency would minimize possibility of loss crops in spite of simple technology. These systems despite of limitation of sources enjoy merits of sponsors traditions and intelligent methods of using animals, fields, and compatible crop species. Thus ecological agriculture scholars consider these systems as unique samples to determine sustainability standards in agricultures activities

Abstract: Asphaltene precipitation and deposition occur in petroleum reservoirs as a change in pressure, temperature and liquid phase composition. It is great importance to investigate the asphaltene content hysteresis under change of effective factors on thermodynamic conditions such as pressure, temperature and composition. In the present work the asphaltene content hysteresis was investigated during natural depletion. Experimental procedure includes decreasing pressure from initial reservoir pressure to near saturation pressure and investigating asphaltene content hysteresis during redissolution process at reservoir temperature. At each step IP143 standard test was used to measure precipitated asphaltene. The results of the study indicated that reservoir fluid was located at unstable region. It was concluded that, above saturation pressure, asphaltene precipitation has a low asphaltene content hysteresis and pressurizing is acceptable method for solving the problem in this heavy asphaltenic crude oil.  Also density measurement of flashed oil confirmed that there is a little hysteresis in asphaltene content during redissolution and precipitation processes.

Abstract: Worldwide many electrical equipment insulation failures have been reported caused by switching operations, while those equipments had previously passed all the standard tests and complied with all quality requirements. The problem is mostly associated with high-frequency overvoltages generated during opening or closing of a switching device. The transients generated during switching operations in a Gas Insulated Substation (GIS) are associated with high frequency components in the order of few tens of MHz. The frequency spectrum of the VFTO generated in the 220/66 kV Wadi-Hoff GIS is analyzed using Fast Fourier Transform technique. The main frequency with high voltage amplitude due to the operation of disconnector (DS5) is 5 to 10 MHz, with the highest amplitude at 9 MHz. The main frequency with high voltage amplitude due to the operation of circuit breaker (CB5) is 1 to 25 MHz, with the highest amplitude at 2 MHz. Mitigating techniques damped the oscillating frequencies effectively. The using of cable terminal reduced the frequency oscillation effectively than that of OHTL terminal. The using of a shunt capacitance results in vanishing the high frequency components. Ferrite rings reduces the high frequency components effectively especially in the range 2 to 7 MHz. The using of RC and RL filters results in vanishing the high frequency components.

Abstract: Selecting the right technology is always a difficult task for decision-makers. Technologies have varied strengths and weaknesses which require careful assessment by the purchasers. The purpose of this paper is applying a new integrated method to technology selection. Proposed approach is based on Logarithmic fuzzy preference programming and GTMA methods. Logarithmic fuzzy preference programming method is used in determining the weights of the criteria by decision makers and then rankings of technologies are determined by GTMA method. A numerical example demonstrates the application of the proposed method.
