AN EMPIRICAL STUDY ON MEDIATED MULTI-ROUTES TR MODEL BASED ON SC PLATFORM

With the new era of intellectual economic, intellectual capital became the critical components of wealth creation. Core employees with higher organizational performance characteristics are often entitled Talent for their key networking status in creating the organizational intelligent capital values. They can also be competed hotly by other competitor in human capitall market. In the field of talents’ retention (TC), the empirical study of relationship-oriented between talents’ performance and voluntary turnover by modeling is taking lead way in highlighting the talents’ turnover mechanism. This paper, after survey in the cross- industries samples, developed talents’ performance characters- withdraw tendency model by introducing social capital (SC) construction and way of combination of the literature methodology and the empirical study.Talent retention, Social capital, Performance character, Withdraw tendency

The Role of Solution Chemistry and Cell Surface Properties in Mediating Bacterial Transport and Deposition in Porous Media and Interactioin with Nanomaterials

Groundwater is an important source for drinking water supply. Microbial contaminants have been implicated in two-third of the waterborne disease outbreak. Understanding the fundamental processes, the governing factors and the interfacial interactions that contribute to the deposition of microbial contaminants to porous media will help to elucidate the microbial attachment/transport profile and is highly needed for bioremediation in the environment as well as water purification industry. In this study, the effects of (1) chemical factors including ionic strength, pH and concentration of phosphate, (2) biological factors including lipopolysaccharide (LPS), biofilm and biofilm extracellular polysaccharide (EPS), and strain type on E.coli O157:H7\u27s transport and deposition in saturated sand columns were investigated. The contributions of surface charge, hydrophobicity and steric force to bacterial attachment were quantitatively assessed by calculating extend DLVO theory and steric interaction. Moreover, the role of LPS in protecting bacteria from antibacterial effect of graphene oxide(GO) was studied. At last, the role of surface functional groups in antibacterial activities of carbon nanotubes was examined. The overall findings in our study are as follows: (1) The transport of E.coli O157:H7 through saturated porous media is enhanced with increasing ionic strength and pH condition; (2) The presence of phosphate in water body encourages the transport of E.coli O157:H7 cells through porous media; (3) LPS on the cell surface facilitate E.coli O157:H7\u27s transport in sand columns; (4) The retention of E.coli O157:H7 in sand is significantly lower than E.coli JM109 under various solution chemical conditions; (5) The association of E.coli bacteria with biofilm coated on the porous media substantially increase the attachment of cells; (6) XDLVO integrating with steric interaction can qualitatively explain our observations about the retention of E.coli O157:H7 on sand surface; (7) The LPS component can protect E.coli O157:H7 cells from antibacterial activities of GO sheets; (8) Carbon nanotubes functionalized with amine groups have the highest bacterial removal efficiency. The adsorption of bacteria to the nanomaterials fits to Langmuir isotherm equation and can be expressed by pseudo second order kinetics equation

An Aircraft Ranging Algorithm Based on Two Frames of Image in Monocular Image Sequence

We proposed a novel rotation-invariant feature based passive ranging algorithm to estimate the distance of an imaged non-cooperation target to camera. This improved algorithm avoids sometimes occurrence of physically unreasonable results in solving the existing quartic equation, such as the happening of complex or negative value. This method uses three matched points in two adjacent frames of an image sequence to extract depth-dependent line features of the target. With this line features combination of the observer’s displacement and imaging directions, a quadratic equation was build to estimate the distance. Analysis shows that the proposed new passive ranging equation would be solvable when the observer is with non-zero displacement in adjacent sampling instances. Our reduced-model experiment also demonstrates that the proposed algorithm is not only simple and feasible but also with a relative ranging error no more than 4 per cent in most cases.Defence Science Journal, Vol. 64, No. 1, January 2014, DOI:10.14429/dsj.64.288

An Experimental Investigation of Hyperbolic Routing with a Smart Forwarding Plane in NDN

Routing in NDN networks must scale in terms of forwarding table size and routing protocol overhead. Hyperbolic routing (HR) presents a potential solution to address the routing scalability problem, because it does not use traditional forwarding tables or exchange routing updates upon changes in network topologies. Although HR has the drawbacks of producing sub-optimal routes or local minima for some destinations, these issues can be mitigated by NDN's intelligent data forwarding plane. However, HR's viability still depends on both the quality of the routes HR provides and the overhead incurred at the forwarding plane due to HR's sub-optimal behavior. We designed a new forwarding strategy called Adaptive Smoothed RTT-based Forwarding (ASF) to mitigate HR's sub-optimal path selection. This paper describes our experimental investigation into the packet delivery delay and overhead under HR as compared with Named-Data Link State Routing (NLSR), which calculates shortest paths. We run emulation experiments using various topologies with different failure scenarios, probing intervals, and maximum number of next hops for a name prefix. Our results show that HR's delay stretch has a median close to 1 and a 95th-percentile around or below 2, which does not grow with the network size. HR's message overhead in dynamic topologies is nearly independent of the network size, while NLSR's overhead grows polynomially at least. These results suggest that HR offers a more scalable routing solution with little impact on the optimality of routing paths

Infinitely many sign-changing solutions for an elliptic equation involving double critical Hardy–Sobolev–Maz’ya terms

In this paper, we consider the existence of infinitely many sign-changing solutions for an elliptic equation involving double critical Hardy–Sobolev–Maz’ya terms. By using a compactness result obtained in [C.H. Wang, J. Yang, Infinitely many solutions for an elliptic problem with double Hardy–Sobolev–Maz’ya terms, Discrete Contin. Dyn. Syst., 36(3):1603–1628, 2016], we prove the existence of these solutions by a combination of invariant sets method and Ljusternik–Schnirelman-type minimax method
