A Wireless Inductive-Capacitive Resonant Circuit Sensor Array for Force Monitoring  [PDF]
Andrew J. DeRouin, Brandon D. Pereles, Thadeus M. Sansom, Peng Zang, Keat Ghee Ong
Journal of Sensor Technology (JST) , 2013, DOI: 10.4236/jst.2013.33011
Abstract: A wireless passive sensor array based on inductive-capacitive (LC) resonant circuits capable of simultaneously tracking two points of force loading is described. The sensor consisted of a planar spiral inductor connected to two capacitors forming a resonant circuit with two resonant frequencies. When a load was applied to one or both of the parallel plate capacitors, the distance between the plates of the capacitor was altered, thus shifting the observed resonant peaks. Testing illustrated that applied loading to a particular capacitor caused a significant shift in one of the resonant peaks and also a smaller shift in another resonant peak. This interdependence resulted from each capacitive element being connected to the same inductive spiral and was accounted for with a developed analysis algorithm. To validate the experimental observation, a circuit simulation was also generated to model the sensor behavior with changing force/displacement. The novelty of this system lies not only in its wireless passive nature, but also in the fact that a single LC sensor was fashioned to detect more than one point simultaneously.
Heuristics for Production Allocation and Ordering Policies in Multi-Plants with Capacity  [PDF]
Jie Zang, Jiafu Tang
Journal of Service Science and Management (JSSM) , 2010, DOI: 10.4236/jssm.2010.31002
Abstract: Joint decisions in production allocation and ordering policies for single and multiple products in a production-distribution network system consisting of multiple plants are discussed, production capacity constraints of multi-plants and unit production capacity for producing a product are considered. Based on the average total cost in unit time, the decisive model is established. It tries to determine the production cycle length, delivery frequency in a cycle from the warehouse to the retailer and the economic production allocation. The approach hinges on providing an optimized solution to the joint decision model through the heuristics methods. The heuristic algorithms are proposed to solve the single-product joint decision model and the multi-products decision problem. Simulations on different sizes of problems have shown that the heuristics is effective, and in general more effective than Quasi-Newton method (QNM).

Core-Germplasm Construction of Rosa rugosa Collections by CDDP Molecular Markers  [PDF]
Liyuan Jiang, Dekui Zang
Open Journal of Applied Sciences (OJAppS) , 2017, DOI: 10.4236/ojapps.2017.711046
Abstract: A method for constructing core-germplasm of Rosa rugosa in China based on molecular marker data was probed and the optimum core germplasm was established. Studies were initiated to analyze the genetic diversity of 120 rugged roses from 6 different Chinese source populations based on CDDP marker, and a preliminary construction of the core collection was established using stepwise UPGMA clustering sampling method. The 26 core collection resources of R. rugosa collections in China have 20% germplasm samples of initial collection, the retention ratio of polymorphic loci, effective number of alleles (Ne), Nei’s genetic diversity (H) and Shannon information index (I) were respectively 97.52%, 104.16%, 108.38% and 106.18%. The results of t-test showed that no significant difference was found in genetic diversity indexes between the core collection and the original collection. These results also demonstrated that the core collection could stand for original collection excellently. The results show that CDDP molecular technology can be successfully applied to the construction of core germplasm resources of rugged roses.
High Temperature Thermodynamics of the Ferromagnetic Kondo-Lattice Model
H. Roder,R. R. P. Singh,J. Zang
Physics , 1997, DOI: 10.1103/PhysRevB.56.5084
Abstract: We present a high temperature series expansion for the ferromagnetic Kondo lattice model in the large coupling limit, which is used to model CMR perovskites. Our results show the expected cross-over to Curie-Wei{\ss} behavior at a temperature related to the bandwidth. Estimates for the magnetic transition temperatures are in the experimentally observed range. The compressibility shows that the high temperature charge excitations can be modeled by spinless fermions. The CMR effect itself, however, warrants the inclusion of dynamic effects and cannot be explained by a static calculation.
Blow-Up Criteria for Three-Dimensional Boussinesq Equations in Triebel-Lizorkin Spaces

Discrete Dynamics in Nature and Society , 2012, DOI: 10.1155/2012/539278
Abstract: We establish a new blow-up criteria for solution of the three-dimensional Boussinesq equations in Triebel-Lizorkin spaces by using Littlewood-Paley decomposition. 1. Introduction and Main Results In this paper, we consider the regularity of the following three-dimensional incompressible Boussinesq equations: where denotes the fluid velocity vector field, is the scalar pressure, is the scalar temperature, is the constant kinematic viscosity, is the thermal diffusivity, and , while and are the given initial velocity and initial temperature, respectively, with . Boussinesq systems are widely used to model the dynamics of the ocean or the atmosphere. They arise from the density-dependent fluid equations by using the so-called Boussinesq approximation which consists in neglecting the density dependence in all the terms but the one involving the gravity. This approximation can be justified from compressible fluid equations by a simultaneous low Mach number/Froude number limit; we refer to [1] for a rigorous justification. It is well known that the question of global existence or finite-time blow-up of smooth solutions for the 3D incompressible Boussinesq equations. This challenging problem has attracted significant attention. Therefore, it is interesting to study the blow-up criterion of the solutions for system (1.1). Recently, Fan and Zhou [2] and Ishimura and Morimoto [3] proved the following blow-up criterion, respectively: Subsequently, Qiu et al. [4] obtained Serrin-type regularity condition for the three-dimensional Boussinesq equations under the incompressibility condition. Furthermore, Xu et al. [5] obtained the similar regularity criteria of smooth solution for the 3D Boussinesq equations in the Morrey-Campanato space. Our purpose in this paper is to establish a blow-up criteria of smooth solution for the three-dimensional Boussinesq equations under the incompressibility condition in Triebel-Lizorkin spaces. Now we state our main results as follows. Theorem 1.1. Let , be the smooth solution to the problem (1.1) with the initial data for . If the solution satisfies the following condition then the solution can be extended smoothly beyond . Corollary 1.2. Let , be the smooth solution to the problem (1.1) with the initial data for . If the solution satisfies the following condition then the solution can be extended smoothly beyond . Remark 1.3. By Corollary 1.2, we can see that our main result is an improvement of (1.2). 2. Preliminaries and Lemmas The proof of the results presented in this paper is based on a dyadic partition of unity in Fourier

Abstract: In the title molecule, [Fe(C5H5)(C16H12N)], the cyclopentadienyl rings are approximately eclipsed and the interplanar angle is 0.8 (7)°. The Fe atom is slightly closer to the substituted cyclopentadienyl ring, with an Fe...centroid distance of 1.639 (2) , compared with 1.645 (2) for the unsubstituted ring. The C=N double bond is essentially coplanar with the substituted cyclopentadienyl ring with a deviation of 10.3 (1)°. The angle formed by the C=N double bond and the naphthalene ring system is 47.1 (1)°. The C—N=C—C torsion angle is 177.32 (5)°.

International Business Research , 2009, DOI: 10.5539/ibr.v1n1p23
Abstract: A Company is to provide telecommunications, internet billing platform and supporting services technology companies. As a knowledge-intensive small and medium-sized enterprise, human resources is the company’s core competitiveness, companies continue the “people-oriented” core values, and human resources to a strategic height. This is the company survival and development of important support for the company’s success is based on human resources management. A company’s operating and development, utilization of human resources and other management knowledge, analysis of Company A in the management of the problem still exists, make a few constructive comments.
