We have studied the refining effects of refining agents and ultraviolet transmitting property of soda lime glass, for the purpose of developing ultraviolet transmitting glass with soda lime glass composition which is one of an inexpensive glasses. It was found that for glass that requires ultraviolet transmitting property, antimony oxide, which is commonly used as a refining agent, cannot be us...

We study the energy-efficient configuration of multihop paths with automatic repeat request (ARQ) mechanism in wireless ad hoc networks. We adopt a cross-layer design approach and take both the quality of each radio hop and the battery capacity of each transmitting node into consideration. Under certain constraints on the maximum tolerable transmission delay and the required packet delivery rat...

Multiple regression of genetic evaluations for milk yields of first lactations of 159 Holstein bulls on sire, dam, and maternal grandsire evaluations indicates that the weight for estimated transmitting ability of the dam calculated from the first record of the dam and first records of her herdmates is about as theoretically expected and is markedly superior both to estimated transmitting abili...

In this paper, transmitter polarization optimization is firstly proposed to improve the accuracy of azimuth-elevation arrival angles estimation within MIMO electromagnetic vector-sensor array (EMVA). Minimizing of Cramér-Rao bound is used as cost function for the optimal design of transmitting signal polarization. Computer simulation results verify that the optimal polarization design provides ...

Picture archiving and communication systems (PACS) require highspeed networks to transmit large image files between components. While transmitting data through public networks, privacy, authenticity, and integrity have always been some critical problems. Recent years, IPv6 brings significant improvements in mechanisms for assuring a higher level of security. In this paper, we first analyzes how...

the application of laser in dentistry is considered as a favorable technique for patients due to its many advantages compare to other current methods. one of the main goals in pediatric dentistry is to provide the treatment as comfortable as possible without any risks for the care. laser is being used in different pediatric dental conditions including caries detection, caries removal and cavity...
