Electron spin resonance (ESR) spectrometry is the most direct and sensitive method for detecting certain reactive oxygen species (ROS)1. By ESR diagnosis, plasma-water reactions can be elucidated, which is meaningful for guiding its clinical application.
A direct current atmospheric pressure cold plasma jet was used to inactivate Staphylococcus aureus (S. aureus) suspended in a liquid. Three types of gases, pure argon (99.999%), argon with 2% oxygen, and argon with 2% oxygen and 10% nitrogen were used as operating gases respectively. The inactivation efficacies for the plasma jets operating in the three gases decrease from Ar/O2(2%) to Ar/O2(2%)/N2(10%)...
The designing of networked command and control(C2) organization is one of the key technologies to the realization of network centric warfare(NCW). This paper reviews the recent existing methods of C2 organizational design. Firstly, the problem of networked C2 Organizational Design is depicted, then the four existing methods of designing C2 organization are surveyed, and the flows of these four methods...
Content Centric Networking (CCN) is a new network infrastructure around content dissemination and retrieval, shift from host addresses to named data. Each CCN router has a cache to store the chunks passed by it. Therefore the caching strategy about chunk placement can greatly affect the whole CCN performance. This paper proposes an implicit coordinate chunk caching location and searching scheme (CLS)...
Radiation performance of the UHF-band invert-F antenna array on the cylindrical metal body is analyzed. Firstly, a low-profile UHF-band inverted-F antenna structure is designed. And several design parameters of the inverted-F antenna are discussed. Secondly, two kinds of the inverted-F antenna array on the cylindrical metal body are simulated. And the effect of the supporting structure on antenna...
This paper studied preventive software maintenance policy based on ant colony algorithm. The entire system was divided into several subsystems and each subsystem has 4 kinds of maintenance policies with different maintenance cost. This model can obtain optimal preventive maintenance policy of each subsystem which guarantees excellent software system reliability with relatively lower costs. An example...
In this paper, micro-particle swarm optimizer (MICROPSO) is improved and applied on the reactive power optimization problem. Self-adapted mutation operator is introduced in MICROPSO. For self-adapted mutation operator, mutation ratio is inverse-proportional to the fitness. So particles with worse fitness have higher mutation probability, and the algorithm can evolve. The self-adapted mutation operator...
In order to analyze low gravity influence to the tractive performance of lunar rover effectively, similitude methodology was introduced to investigate the lunar wheel-soil interaction. The key parameters of the system between lunar soil and rover wheel were selected at first, the terramechanical model of the system under lunar gravity was created according to similarity theorem, then the feasibility...
We demonstrate low-loss fiber-to-chip coupling using 7.3 μm long silicon strip waveguide cantilever couplers. Average coupling losses are measured to be less than 0.62 dB per connection throughout the optical telecommunications C band.
Two Alkane monooxygenase genes (AlkB), AlkB1 and AlkB2 were cloned from two Acinetobacter strains, JH250-5 and JH250-8, which can degrade oil efficiently. AlkB1 exists in both strains, while AlkB2 exist in JH250-8 only. Bioinformatics analysis results showed that, two AlkB1s were highly homologous in DNA or amino acid sequence, and were very similar in predicted protein structure. AlkB2 of JH250-8...
Using crude oil as the sole carbon source, four indigenous microorganisms with oil degradation, JH250-5, JH250-8, JH250-10, and JH250-12, were isolated from heavy oil polluted soil. The oil degradation rate of JH250-8 was over 90% which was much higher than other strains. 16RNA gene sequencing results showed those four strains are all belong to Acinetobacter. GC and GC-MS analysis indicate that, the...
The traffic control of On-Ramp is the most widely used as a expressway control strategy, according to the relationship of the controlled on-ramp, The control of On-Ramp can be divided into the isolated control and coordinated control. Based on the theory and the method of the control above, the two control are classified discussion, summarizing the kinds of control theories and the characteristics...
First, this study presents the concept of heavy equipment transport and the existed problem of turning at bend. Then, considering the characteristics of heavy equipment transport and through preliminary technique analysis and hypothesis, make a dynamic model of the vehicles and cargoes and modify it according to its potential problems. In the end, to take the practical conditions of heavy equipment...
Visualization modeling based on DAQ (Data Acquisition) of SHM (Structural Health Monitoring) system helps nondestructive and Intelligent evaluation on structure. It makes up the shortage of traditional visual methods and speeds up mastering the state of structural health. It promotes the security of structure greatly. Using simulation data from the Key Laboratory of Structural Engineering and Earthquake...
In order to reduce the high complexity of overlapped code division multiplexing (OvCDM) system, a novel simplified OvCDM (S-OvCDM) system with constraint length 1 is proposed in the paper. With reduced constraint length, system complexity is greatly reduced and bit error rate (BER) analysis is simplified. Design criteria of the novel system is set up based on its equivalence to bit interleaved coded...
High spectral efficiency coded modulation schemes would induce complex quantifier and high peak to average ratio (PAPR) due to great number of constellation points. Based on the idea that a one-to-one mapping is only necessary from information bit sequences to channel symbol sequences, a novel scheme is proposed to reduce the constellation size. Key parameter of the system includes code rate, constellation...
In this paper, a new efficient scheme is proposed for the fast detection in spatially correlated MEMO systems. By adding cutting planes to the original semi definite relaxation scheme, the new method shows more robustness than other fast detection schemes towards the increasing condition number of the channel matrix, which is always caused by the correlation between different antennas. In order to...
Service-based systems (SBSs) are distributed systems which have many advantages, including rapid composition of services for distributed applications. In these systems, various capabilities are provided by service providers as services interconnected by networks. It is important for users of SBSs to have confidence in the trustworthiness of service providers. Existing approaches to trust estimation...
The three dimensional magnetohydro dynamic (MHD) model of vacuum arc was obtained based on two-fluid model of ion and electron and Maxwell equation. In the MHD model, mass conservation equation, momentum conservation equations, energy conservation equations of ion and electron, voltage equations and magnetic equations were considered. Characteristics of large-current vacuum arc were simulated and...
