In conformity with the request for search and rescue application, the design criterions of human-robot interaction are proposed. Based on the human-robot interaction, the control station system for the shape-shifting search and rescue robot is designed. The system mainly has four features, which are completely perceptive information, flexible control, friendly interface and strong interaction. The experiments demonstrate that the control station system for search and rescue robots can control motion and exchange the multi-channel information in the complex simulated after-earthquake environment. Thus, feasibility and validity of the control station system have been proved in the fields of search and rescue.

A comparison of particle swarm optimizations for uncapacitated multilevel lot-sizing problems

Journal of Japan Industrial Management Association 2010年第3期61卷 203-213页

The multilevel lot-sizing (MLLS) problem is a key production planning problem in the material requirement planning (MRP) system. The MLLS problem deals with determining the production lot sizes of various items appearing in the product structure over a given finite planning horizon to minimize the production cost, inventory carrying cost, backordering cost, etc. In a previous study, a particle swarm optimization (PSO) algorithm integrated with flexible inertial weight (WPSO-MLLS) was proposed for uncapacitated MLLS problems by embedding the characteristics of the MLLS problem, a coding system and redefinitions of operators for 'velocity' plus 'velocity', 'position' plus 'velocity', and 'position' subtract 'position'. This research further investigates the suitability of WPSO-MLLS by comparing the solving performance of WPSO-MLLS with a PSO algorithm without inertial weight (PSO-MLLS) and two extended hybrid versions of PSO, which are WPSO-MLLS integrated with crossover and mutation operators of a genetic algorithm (GA) (HWPSO-MLLS) and PSO-MLLS integrated with crossover and mutation operators of GA (HPSO-MLLS). Some benchmarking testing instances are adopted to compare these PSO algorithms.

Acta Metallurgica Sinica(English Letters) 2009年第4期22卷 291-296页

The thermal dissolved sulfuration technology is brought forward and performed based on the characteristic of low grade lead-zinc oxide ore in lanpin. Using sulfur as the sulphidizing agent in the experiment, the oxides in the sandstone and ignimbrite are changed into sulfides. The disproportionation reaction of sulfur in a solution is confirmed as 4S＋3H2O=2S^2-＋S2O3^2--＋6H^＋. The dynamics process is studied and the first-order reaction rate equation -1n（1-a）=ktt is obtained. The effects of the reactive products, stirring speed, dosage of sulfuration agent, value of pH and sulphidizing temperature on the sulfuration of oxide ore are investigated. The results indicate that the reactive apparent activation energy is 100.8 kJ/mol and the sulfuration ratio of lead-zinc oxide ore reaches 60% under the conditions of pH 5.9-7.5, the sulfuration temperature of 130 ℃, sulfuration time of 180 min and the stirring speed of 800 r/min.

The slashing is a very important procedure in textile manufacturing process which can improve warp quality, loom efficiency and reduce warp break. A hybrid modeling method is proposed for textile slashing process. Data are divided to multiple subsets by clustering algorithm, and then artificial neural networks (ANN) and partial least square (PLS) regression are used to model multiple sub-models respectively according to size of subset. The weight coefficient of sub-model is obtained by Lagrange multiplier method, and the whole model is established by combining multiple sub-models. The simulation result shows that the proposed hybrid modeling method has a better predictive accuracy and robustness. © 2009 IEEE.

Enigmatic new ungulates from the Early Middle Eocene of central Anatolia, Turkey

Four new ungulate species described here from the early middle Eocene Uzunçarsidere Formation, near Ankara, Turkey present a phylogenetic and biogeographic puzzle. The four species, known from jaws, teeth, and skull and postcranial fragments, share a suite of diagnostic dental features (selenolophodont molars, all lower molars lacking hypoconulids, premolars with metacones small or absent, and narrow, short premolar talonids) and are included in a single new genus, Hilalia. Hilalia saribeya, H. selanneae, H. sezerorum, and H. robusta are distinguished from each other by size and details of premolar morphology. Cladistic analysis indicates that although Hilalia shares a common ancestor with perissodactyls, hyracoids and some “condylarths” to the exclusion of artiodactyls, its position relative to those taxa is unresolved—the calcaneum lacks derived features of artiodactyl, perissodactyl or hyracoid calcanea, some features of Hilalia's molar morphology are convergent with features in some hyracoids, perissodactyls, and selenolophodont “condylarths”, and Hilalia has more primitive premolars than most members of those groups. The affinities of some other members of the Uzunçarsidere mammal fauna, including an embrithopod, marsupials, and a possible proboscidean, have suggested that central Anatolia may have served as a biogeographic crossroads for mammalian dispersal among Asia, Africa, and Europe during the early Paleogene. However, the absence of convincing links between Hilalia and any of the increasingly well-known Paleogene ungulates of Asia, Indo-Pakistan, and Africa, or those of Europe and North America suggests that our understanding of early Paleogene ungulate evolution and biogeography is far from complete.

Active Power Filter (APF) is usually used to compensate the harmonic and reactive currents which are generated by the nonlinear load, and its compensation performance mainly depends on the design of controller. When the parameters of the line and load are uncertain or unknown, the system may be unstable. In order to solve this problem, this paper adopts the Energy Shaping Repetitive Control (ESRC) to improve the output current waveform of three-phase three-wire shunt active power filter. In this control strategy, the Energy Shaping control is used to guarantee system dynamic performance and the repetitive control is to correct current waveform quality. The new controller design procedure is analyzed in detail. Theoretical analysis and experimental results demonstrate the validity of the proposed method and the filtering performance is improved obviously. © 2009 IEEE.

The Surface Detector of the Pierre Auger Observatory is sensitive to neutrinos of all flavors above 0.1 EeV. These interact through charged and neutral currents in the atmosphere giving rise to extensive air showers. When interacting deeply in the atmosphere at nearly horizontal incidence, neutrinos can be distinguished from regular hadronic cosmic rays by the broad time structure of their shower signals in the water-Cherenkov detectors. In this paper we present for the first time an analysis based on down-going neutrinos. We describe the search procedure, the possible sources of background, the method to compute the exposure and the associated systematic uncertainties. No candidate neutrinos have been found in data collected from 1 January 2004 to 31 May 2010. Assuming an E−2 differential energy spectrum the limit on the single-flavor neutrino is E2dN/dE<1.74×10−7GeVcm−2s−1sr−1 at 90% C.L. in the energy range 1×1017eV

Since the BP neural network algorithm has some unavoidable disadvantages, such as slowly converging speed and easily running into local minimum, the genetic algorithm and simulated annealing algorithm with the overall search capability have been put forward to optimize authority value and threshold value of BP nerve network. In this paper, a new neural network model which is optimized by genetic algorithm and simulated annealing algorithm has been established and applied into the freight volumes forecast. The result shows that the optimized neural network has significant advantages inspect of fast convergence speed, good generalization ability and not easy to yield minimal local results. In generally, the optimized neural network exhibits good representation and strong prediction ability, and is a helpful tool in the future freight volumes prediction. ©2009 IEEE.
