Adaptive modulation MIMO system based on minimizing transmission power

引用

Journal of Zhejiang University-Science A(Applied Physics & Engineering) 2006年第6期7卷 1046-1050页

作者： wang zhi-ying HE Chen Department of Electronics Engineering Shanghai Jiao Tong University Shanghai 200240 China

Adaptive modulation (AM) is an effective technique to approach the theoretical bound of multi-input and multi-output (MIMO) channel. In most previous studies, the AM parameters were obtained by maximizing the transmission rate for a given total transmit power. In this paper, a novel AM-MIMO algorithm is presented, which is based on minimizing total transmit power when the link’s QoS requirements are given. By taking the QoS requirements into account directly, the proposed algorithm not only makes the system more flexible, but also makes the cross layer design of wireless network easier. At last, the numerical results of the proposed scheme are presented.

The ceramic insulators of spark plugs in gasoline engines are especially prone to damage when deto-knock *** under-stand the damage process and mechanism,the present work investigated the impact resistance of ceramic insulators using detonation waves as impact sources.A test device that generates detonation waves was developed,representing a novel means of evaluating the knock resistance of ceramic *** impact types and detonation intensities were employed,and detonation initiation and propagation at peak pressures greater than 100 MPa were assessed using synchronous high-speed direct photography and pressure *** test results demonstrate that ceramic insulators tend to break at the base of the breathing chamber when damaged by a single high peak pressure detonation wave *** contrast,multiple low pressure impacts eventually break the insulator into multiple *** data also show that the positioning of a ground electrode upstream of the ceramic insulator greatly increases the resistance of the ceramic to the detonation impact.A two-dimensional computational fluid dynamics simulation coupled with a chemical kinetics analysis demonstrated that this improved resistance can be ascribed to a reduced peak pressure that appears after the detonation wave diffracts from the electrode prior to contacting the ceramic insulator.

We investigate the entanglement of formation for a class of high-dimensional quantum mixed states. We present a kind of generalized concurrence for a class of high-dimensional quantum pure states such that the entanglement of formation is a monotonically increasing convex function of the generallzed concurrence, from the monotonicity and convexity the entanglement of formafion for a class of high-dimensional mixed states has been calculated analytically,

Total Atomic Scattering Factors of 1s^23s ~2S States for Lithium Isoelectronic Sequence

引用

Communications in Theoretical Physics 2008年第8期50卷 473-476页

作者： CHEN Chao wang zhi-Wen Department of Physics Beijing Institute of Technology Beijing 100081 China College of Physics and Electronic Technology Liaoning Normal University Dalian 116029 China

Total atomic scattering factors for the 1s^23s ^2S stages for the lithium isoelectronic sequence from Z = 3 - 10 are calculated by using the full core plus correlation wave function. The influence of electron correlation on total atomic scattering factors is considered sufficiently in our calculation. For the 1s^2 3s ^2S states of the lithium isoelectronic sequence, the general functional behaviour of total atomic scattering factors is analyzed together for each state of the isoelectronic sequence.

Analysis of nitrobenzene compounds in water and soil samples by graphene composite-based solid-phase microextraction coupled with gas chromatography–mass spectrometry

引用

Chinese Chemical Letters 2014年第11期25卷 1449-1454页

作者： Gui-Jiang Zhang Xin Zhou Xiao-Huan Zang zhi Li Chun wang zhi wang Department of Chemistry College of Science Agricultural University of Hebei

In this work, solid-phase microextraction coupled with gas chromatography–mass spectrometry was developed to determine trace levels of nitrobenzene compounds in water and soil samples. Graphene was chosen as the extraction material and its composite was coated on a stainless steel wire through sol–gel technique for the solid phase microextraction. The key parameters influencing the extraction efficiency were optimized. Under the optimal conditions, the linearity for the compounds was observed in the range of 0.02–15.0 mg/L for water samples, and 0.2–60.0 mg/kg for soil samples, with the correlation coefficients（r） of 0.9966–0.9987. The limits of detection of the method were 0.0025–0.005 mg/L for water samples, and 0.02–0.04 mg/kg for soil samples. The recoveries for the spiked samples were in the range of 72.0%–113.2%, and the precision, expressed as the relative standard deviations, was less than 12.1%.

Cryopreservation of Queen Honeybee (Apis mellifera carnica) Born Worker Eggs by Vitrification

引用

Agricultural Sciences in China 2010年第9期9卷 1353-1361页

作者： LI zhi-yong XUE Yun-bo wang zhi LI Xing-an Key Laboratory for Honeybee Genetics and Breeding Jilin Provincial Apiculture Institute Jilin 132108 P.R. China

Many species of insect egg can be targeted individually or （and） collectively for cryopreservation by vitrification. However, there has been no report on cryopreservation of honeybee eggs by vitrification. In an attempt to define a preliminary procedure of cryopreservation of honeybee eggs by vitrification, queen honeybee born worker eggs （worker eggs） were stored through vitrification in liquid nitrogen up to 1 h, and then post-vitrification survival of the vitrified worker eggs in vitro and their hatching rates during maturation in vivo were observed using microscopic and close visual inspections. The procedure of cryopreservation by vitrification included dechorionation with sodium hypochlorite and permeabilization with isopropyl alcohol; equilibration by addition of loading solution （i.e., 25% vitrification storage solution） and dehydration by gradual replacement of loading solution with vitrification storage solution; cooling in liquid nitrogen vapor right before droplet vitrification in liquid nitrogen; and recovery in liquid nitrogen vapor right after storage in liquid nitrogen, thawing at temperature of thawing medium （5% sucrose in TC 100-insect medium） and rehydration by gradual replacement of vitrification storage solution with rehydration solution （5% fetal bovine serum in TC 100-insect medium）. It was found that among the worker eggs experiencing cyropreservation by vitrification, 1.25% of them were successfully passed through the four life stages, viz., egg, larva, pupa, and adult. In summary, it can be inferred that although a majority of worker eggs were dead after cyropreservation by vitrification, a few of them were developed into larvae, pupae, and finally emerged as adults.
