This paper presents a novel hierarchical network planning model for global logistics (GLs) network configurations. The proposed method, which is based on the fundamentals of integer programming and hierarchical cluster analysis methods, determines the corresponding locations, number and scope of service areas and facilities in the proposed GLs network. Therein, a multi-objective planning model is formulated that systematically minimizes network configuration cost and maximizes both operational profit and the customer satisfaction rate. Particularly, potential risk-oriented costs, such as macro-environmental-risk and micro-operational-risk costs are considered in the proposed model. Numerical results indicate that the overall system performance can be improved by up to 11.52% using the proposed approach. (C) 2011 Elsevier Inc. All rights reserved.

"The positive artifacts in particulate organic carbon fractions for fine particles (PM2.5) and nanoparticles (PM0.1) were characterized in a tunnel environment by using the QBQ (a quartz filter behind a quartz filter) method. The OC concentrations of the backup quartz filters ranged from 3.56 to 11.38 mu g m(-3) with the average of 6.70 mu g m(-3) for PM2.5, and from 2.62 to 7.27 mu g m(-3) With the average of 4.64 mu g m(-3) for PM0.1. The most abundant species on the backup quartz filters was OC1 for both PM2.5 and PM0.1, accounting for 56.9% and 41.1% of the measured organic carbon, respectively. Most of EC fractions (EC1-EC3) on the backup filters for PM2.5 and PM0.1 were below the minimum detection limit. Therefore, only OC contributed to positive artifacts distinctly with the average percentage of 21.7% and 48.0% for PM2.5 and PM0.1, respectively. The artifacts for four organic carbon fractions ranged from 36.1% (OC1) to 4.4% (OC4) for PM2.5 and from 68.0% (OC1) to 31.9% (OC4) for PM0.1]. The uncorrected OC/EC ratios on the front quartz filters were higher by as much as 30% and 107% for PM2.5 and PM0.1 than those corrected for positive organic artifacts, respectively. That is, much higher percentage of positive artifacts was found for PM0.1 DC fractions on the front filters. The comparison of the present and previous studies shows that OC positive artifacts vary widely among various PM fractions and sampling sites attributing to many factors that are worth investigating in the future.

In this paper, high-performance bottom-gate (BG) thin-film transistors (TFTs) with zinc oxide (ZnO) artificially location-controlled lateral grain growth have been prepared via low-temperature hydrothermal method. For the proper design of source/drain structure of ZnO/Ti/Pt thin films, the grains can be laterally grown from the under-cut ZnO beneath the Ti/Pt layer. Consequently, the single one vertical grain boundary perpendicular to the current flow will be produced in the channel region as the grown grains from the source/drain both sides are impinged. As compared with the conventional sputtered ZnO BG-TFTs, the proposed location-controlled hydrothermal ZnO BG-TFTs (W/L = 250 mu m/10 mu m) demonstrated the higher field-effect mobility of 6.09 cm(2)/V.s, lower threshold voltage of 3.67 V, higher on/off current ratio above 10(6), and superior current drivability, reflecting the high-quality ZnO thin films with less grain boundary effect in the channel region.

This study explores trust and shared vision moderate the relationship between the manufacturer's influence strategies and supplier delivery flexibility. The major components of this study are based on reviews of marketing research that focus on influence strategies and literature regarding supply chain flexibility. The results show that the request strategy has a negative effect on supplier delivery flexibility. The model predicts that trust and shared vision have an asymmetrical effect across recommendations, information exchange, and promises influence strategies. When the relationship contains a highly shared vision, a manufacturer's use of the recommendation influence strongly promotes supplier delivery flexibility, whereas the use of a promise strategy depresses supplier delivery flexibility. In contrast, an information exchange strategy will have a negative effect, but the promise strategy will have a positive effect on supplier delivery flexibility when trust is high. This paper contributes to guidelines for management on how to align their suppliers for delivery flexibility to respond quickly to customer demands. (C) 2011 Elsevier Inc. All rights reserved.

"In this study, nanoalumina and nanoclay particles were compounded separately with ethylene vinyl acetate (EVA) polymer to produce nanocomposites using a twin-screw extruder to investigate exposure and effective controls. Nanoparticle exposures from compounding processes were elevated under some circumstances and were affected by many factors including inadequate ventilation, surrounding air flow, feeder type, feeding method, and nanoparticle type. Engineering controls such as improved ventilation and enclosure of releasing sources were applied to the process equipment to evaluate the effectiveness of control. The nanoparticle loading device was modified by installing a ventilated enclosure surrounding the loading chamber. Exposures were studied using designed controls for comparison which include three scenarios: (1) no isolation; (2) enclosed sources; and (3) enclosed sources and improved ventilation. Particle number concentrations for diameters from 5 to 20,000 nm measured by the Fast Mobility Particle Sizer and aerodynamic particle sizer were studied. Aerosol particles were sampled on transmission electron microscope grids to characterize particle composition and morphology. Measurements and samples were taken at the near-and far-field areas relative to releasing sources. Airborne particle concentrations were reduced significantly when using the feeder enclosure, and the concentrations were below the baseline when two sources were enclosed, and the ventilation was improved when using either nanoalumina or nanoclay as fillers."

We have demonstrated the capabilities to catch the signals of induced electromotive force (EMF). The characteristics of EMF signals are analyzed systematically. Influences of volumes, sizes and travelling velocities of ferrofluids on the magnitudes and wave spans of the signals are presented. In addition, simulations of the induction fields are carried out to provide the physical insights of the induced EMF signals. The signals can be potentially applied as diagnostic characteristics in the measurements of travelling velocities or sizes of moving ferrofluid drops or slugs.

A novel 3-D bonding technology with cosputtered copper and titanium as bonding material is proposed and investigated based on the diffusion mechanism of cosputtered metal during bonding. This technology features a self-formed adhesion layer for Cu metal layers and interconnects. In addition, cosputtered Cu/Ti bonding exhibits good electrical performance as well as high resistance to multiple current stressing. With the advantages of fabrication efficiency and reliable bond quality, cosputtered Cu/Ti bonding technology presents the potential to be applied in 3-D integration.

Highly uniform current distributions of high resistance state (HRS) and low resistance state (LRS), low 0.6 pJ switching energy, fast 30 ns switching speed, and good 10(6) cycling endurance are achieved in Ni/GeOx/Ta2O5-yNy/TaN resistive random access memory (RRAM) devices. Such good performance is attributed to nitrogen-related acceptor level in Ta2O5-yNy for better hopping conduction, which leads to forming-free resistive switching and low self-compliance switching currents.

With the dramatic growth of fandom population, a considerable amount of research efforts have been devoted to baseball video processing. However, little work focuses on the detailed follow-ups of ball hitting events. This paper proposes a HMM-based ball hitting event exploration system for broadcast baseball video. Utilizing the strictly-defined layout of the baseball field, the proposed system first detects the game-specific spatial patterns in the field, such as the field lines, the bases, the pitch mound, etc. Then, the play region the currently camera-focused region of the baseball field is identified for frame type classification. Since the temporal patterns of presenting the game progress follow a prototypical order, we consider the classified frame types as observation symbols and recognize ball hitting events using HMM. Experiments conducted on broadcast baseball video show encouraging results in frame type classification and ball hitting event recognition. Three practical applications, including highlight clip extraction by user-designated query, storyboard construction, and similar event retrieval, are introduced to address the applicability of our system.

A graph G is pancyclic if it contains a cycle of every length from 3 to vertical bar V(G)vertical bar inclusive. A graph G is panconnected if there exists a path of length l joining any two different vertices x and y with d(G)(x,y) <= l <= vertical bar V(G)vertical bar - 1, where d(G)(x,y) denotes the distance between x and y in G. A hamiltonian graph G is panpositionable if for any two different vertices x and y of G and any integer k with d(G)(x,y) <= k <= vertical bar V(G)vertical bar/2, there exists a hamiltonian cycle C of G with d(C)(x,y) = k, where d(C)(x,y) denotes the distance between x and y in a hamiltonian cycle C of G. It is obvious that panconnected graphs are pancyclic, and panpositionable graphs are pancyclic. The above properties can be studied in bipartite graphs after some modification. A graph H = (V-0 boolean OR V-1, E) is bipartite if V(H) = V-0 boolean OR V-1 and E(H) is a subset of {(u, v) vertical bar u is an element of V-0, v is an element of V-1}. A graph is bipancyclic if it contains a cycle of every even length from 4 to 2 . left perpendicular vertical bar V(H)vertical bar/2right perpendicular inclusive. A graph H is bipanconnected if there exists a path of length 1 joining any two different vertices x and y with d(H)(x,y) <= l <= vertical bar V(H)vertical bar - 1, where d(H)(x, y) denotes the distance between x and y in H and 1 dH(x,y) is even. A hamiltonian graph H is bipanpositionable if for any two different vertices x and y of H and for any integer k with d(H)(x,y) <= k < vertical bar V(H)vertical bar/2, there exists a hamiltonian cycle C of H with d(G)(x,y) = k, where d(G)(x,y) denotes the distance between x and y in a hamiltonian cycle C of H and k - d(H)(x,y) is even. It can be shown that bipanconnected graphs are bipancyclic, and bipanpositionable graphs are bipancyclic. In this paper, we present some examples of pancyclic graphs that are neither panconnected nor panpositionable, some examples of panconnected graphs that are not panpositionable, and some examples of graphs that are panconnected and panpositionable, for nonbipartite graphs. Corresponding examples for bipartite graphs are discussed. The existence of panpositionable (or bipanpositionable, resp.) graphs that are not panconnected (or bipanconnected, resp.) is still an open problem.

This study presents a pilot-scale spray drying system designed to manufacture spherical mesoporous silica particles (MSP) that is capable of producing up to 100 g per hour. The MSP fabricated via a nozzle pressure of 4 kg/cm(2) and a drying temperature of 200 degrees C possess a high specific area of 1012 m(2)/g, a narrow pore size distribution with an average pore diameter of 2.4 nm, and large pore volume of 0.81 cm(3)/g. They were further modified with a tetraethylenepentamine (TEPA-MSP) to enhance CO2 adsorption selectivity from gas streams. The adsorption capacity of 15% CO2 on TEPA-MSP was significantly influenced by adsorption temperature and water vapor of air streams, and reached a maximum of 87.05 mg/g (1.98 mmol/g) at 60 degrees C and 129.19 mg/g (2.94 mmol/g) at a water vapor of 6.98%. The adsorption capacities and the physicochemical properties of TEPA-MSP were preserved through 20 cycles of adsorption-desorption operation. A comparative study revealed that the TEPA-MSP had better adsorption performance of 15% CO2 than the TEPA-modified granular activated carbon and zeolite. These results suggest that the TEPA-MSP can be stably employed in the prolonged cyclic CO2 adsorption and that they possess good potential for CO2 capture from flue gas. (C) 2012 Elsevier B. V.

Utilizing some results in number theory, we propose an efficient method to speed up the computer search of large-order maximum-period Multiple Recursive Generators (MRGs). We conduct the computer search and identify many efficient and portable MRGs of order up to 25,013, which have the equi-distribution property in up to 25,013 dimensions and the period lengths up to 10(233,361) approximately. In addition, a theoretical test is adopted to further evaluate and compare these generators. An extensive empirical study shows that these generators behave well when tested with the stringent Crush battery of the test package TestU01. (C) 2012 Elsevier B.V. All rights reserved.
