Abstract

We introduce a new time-division multiplex wireless power transfer (TDM-WPT) scheme for charging multiple devices with a single transmitter. More specifically, our proposed scheme adopts the intermediate energy storage (IES) circuit which enables storing the received energy from the source temporarily and then supplying it to the load. Thus, by adopting the IES, the receiver can charge the battery with the stored energy in the IES even while the receiver is not performing the direct charging process (from the transmitter). This allows charging multiple receivers simultaneously in a virtual manner, and it eventually leads to the reduction of overall charging time. For the theoretical verification, we analyse the performance of our proposed scheme based on the identical environment and in some selected results. We show that with our proposed scheme the required total charging time can be reduced compared to the conventional TDM-WPT. We also consider practical load (battery charger) requirements which change...

Abstract

Department of Environmental Health Science, Soonchunhyang University(Received July 17, 2012 / Accepted April 30, 2013)Abstract : In university laboratories, areas of studies are becoming diverse and complicated according to the development of the industry. Newforms of potential risk factors are increasing and they are unlike existing ones. In addition, many students are conducting various experiments in the laboratory. Therefore, they could be exposed to risk more often. Despite these risks, people do not recognize university lab safety activities properly and observe safety precautions. They are exposed to various laboratory accidents continually. In this study, we do not apply the present diagnosis method, checklist, but the safety assessment that is widely used in industry. Then we can find lots of hazard that checklist method could miss. This study will use the 4M and Hazard & Operability to design a new Laboratory safety assessments method.Key Words : 4M, HAZOP, laboratory, risk assessment, checklist.

Abstract

A monolayer of L10 FePt nanoparticles was fabricated on a polymer film by introducing a Au seed layer prior to the Fe-Pt deposition on the polyimide film. The particle size distribution was tightened from 5.1plusmn1.8 nm to 3.8plusmn1.1 nm by introducing the Au seeds to induce a preferential nucleation of the deposited metal on the preexisting Au particles. Deposition and annealing was repeated so that well-separated hard magnetic nanoparticles with several nanometers in diameter were achieved in a monolayer configuration. The method can be easily extended to a larger area as well as to other alloy systems to create a monolayer of nanoisland structures on a polymer film.

Abstract

We have developed a novel activation technique for the conformal electroless deposition (ELD) of Cu on a SiO"2 substrate modified with an organic self-assembled monolayer. The SiO"2 substrate was modified with amine groups using 3-aminopropyltriethoxysilane and Au nanoparticles (AuNPs) to form a uniform, continuous catalyst for ELD. The Au catalytic layer formed on the amine-SiO"2 substrate was stabilized by electrostatic interactions between the positively charged protonated-amine self-assembled monolayer (SAM) and negatively charged AuNPs. Cu films were then electrolessly deposited on Au-catalyzed SiO"2 substrates. The Cu seed layer formed by this method showed a highly conformal and continuous structure. Cu electrodeposition on the 60-nm trench was demonstrated using an acid cupric sulfate electrolyte containing chloride, polyethylene glycol 4000 and bis(3-sulfopropyl)disulfide. The resulting electroplated Cu showed excellent filling capability and no voids or other defects were observed in a 60-nm trench pattern.

Abstract

Dent resistance is an important characteristic to avoid damage on automotive outer panels. From a practical point of view, dents can be caused in a number of ways. Considering doors as an example, denting can occur from stone impacts or from the careless opening of an adjacently parked vehicle door. Denting can occur where the door surface is smooth and may not have sufficient curvature to resist dent. These exterior body parts are designed to improve dent resistance using a combination of work hardening and bake hardening. In brief, dent is affected by the shape of the parts and the material properties such as yield strength, strain and thickness. In this work, forming of door outer panel is investigated by Taguchi method. Main parameters are yield strength, thickness, blank size, blank holding force and so on. For the given value of design parameters, forming analysis of the eighteen cases are carried out according to L18 orthogonal array. After comparing the performance by simple conversion of simulation results into dent resistance, the final suggestion of the forming parameters is verified for the optimal improvement of dent resistance.

Abstract

The molecular weight of exo-biopolymer obtained from a submerged culture of Cordyceps sinensis 16 consisted of a main unit and a subunit of 126 and 68 kDa, respectively. The optimal medium for the production of mycelia and exo-biopolymer was determined to be molasses containing 2% sucrose, 0.9% yeast extract, 0.3% K2HPO4, and 0.4% CaCl2. Using optimized medium, maximum productions of mycelia and exo-biopolymer in shake-flask culture were 54.0 g/L and 28.4 g/L, respectively. This study suggests that large-scale production of mycelia and exo-biopolymer by C. sinensis 16 is possible in submerged culture.

Abstract

Recent reports of SCA2 and SCA3 patients who presented with levodopa responsive parkinsonism have generated considerable interest as they have implications for genetic testing. It is unclear whether ethnic race alone or founder effects within certain geographical region explain such an association. In this study, we conducted genetic analysis of SCA2, 3, 17 in an ethnic Chinese cohort with early onset and familial Parkinson's disease (PD) and healthy controls. A total of 191 subjects comprising of 91 PD and 100 healthy controls were examined. We identified one positive case of SCA2 in an early-onset sporadic PD patient who had CAG 36 repeats, yielding a prevalence of 2.2% in early-onset sporadic PD patients and less than 1.0% in our study PD population. The size of the repeats was lower than the expanded repeats (38-57) in SCA2 patients with ataxia in our population. All the children of the patient were physically normal even though some of them carried the repeat expansion of similar size. No cases and controls were positive for SCA3 and SCA17. We do not think routine screening of SCA2, SCA3 and SCA17 for all idiopathic PD patients is cost-effective in our ethnic Chinese population. However, SCA2 should be a differential diagnosis in young onset sporadic PD when genetic mutations of other known PD genes have been excluded.

Abstract

Nanoparticles with different morphology and composition were fabricated inside a polyimide (PI) matrix based on selectively oxidizing a layer of Fe 100− x Pt x alloy metal film sandwiched between two PI precursor layers. γ -Fe 2 O 3 , Pt, and Fe 3 Pt nanoparticles were formed in a monolayer between two PI layers, depending on the alloy film composition and curing conditions. These particles were well-crystallized and sized between 4 and 10 nm. X-ray photoelectron spectroscopy confirmed that Fe in the film preferentially reacted with the organic matrix whereas Pt remained metallic throughout the curing process, which enabled fabrication of particles different morphology and composition. This process can be easily extended to other alloy films, which provides an opportunity to fabricate nanoparticles relatively easily with desired composition and morphology embedded in an inert organic matrix.

Abstract

Using X-ray magnetic circular dichroism (XMCD), the effective magnetic moments for Co and Mn of the thermally annealed Co 53 Mn 25 B 10 Si 12 alloy were estimated. The XMCD results showed that the effective magnetic moments for both Co and Mn were severely reduced by the disordered amorphous structure while the Mn–Mn interaction remained ferromagnetic. We also observed a substantial rise of Co M spin prior to the crystallization of the amorphous structure due to clustering of Co atoms, indicating the onset of devitrification of the amorphous alloy.

Abstract

(Co 0.75 Cr 0.25 ) 80 Si 5 B 15 amorphous alloy was thermally annealed to study the crystallization and magnetic properties. The amorphous alloy crystallized in two stages. The primary crystallization of hexagonal closed packed (Co, Cr) occurred in the initial stage and the rejection of non-magnetic Cr from the crystallized (Co, Cr) crystals was investigated by the temperature dependence of magnetization using a vibrating sample magnetometer. During the second stage, the precipitation of σ-CoCr occurred instead of the eutectic crystallization of borides that is typically observed in most metal-boride glasses. The apparent activation energies for two crystallization stages were estimated to be 318 (±12) and 1690 (±23) kJ/mol, respectively.

Abstract

Ni80Fe20–Mn alloy thin films were fabricated using magnetron sputtering in order to study the microstructural changes that develop in an exchange couple (Ni80Fe20 and Mn). In the process, we discovered that the alloy films phase separated into Ni80Fe20 and Mn when annealed at 400 °C, although bulk Ni80Fe20 and Mn are miscible at room temperature. Moreover, a strong crystallographic texture developed during annealing, especially for films with high Mn content. The increase of texture was attributed to the volume expansion taking place in the phase separation. It was speculated that the as-deposited alloy films had a large coherent interfacial strain, possibly due to inhomogeneous alloying. In turn, this hindered the formation of intermetallic compounds, and instead forced a phase separation to reduce the interfacial energy.

Abstract

Lithium oxide was introduced into the CaZr4(PO4)6 lattice to densify the material to its theoretical density through liquid phase sintering. Although the liquid phase significantly enhanced the densification rate, due to the high solubility of the Li2O liquid phase in the solid, a transient liquid phase was generated, which resulted in microstructures that were extremely sensitive to both composition and processing conditions. It was determined that 1 wt.% addition of Li2CO3 with accelerated sintering schedule produced the theoretical density of CaZr4(PO4)6 and further addition of Li2CO3 rapidly decreased the sintered density. Minimum bulk thermal expansion of negative 5×10−6 °C−1 was obtained with the addition of 5 wt.% Li2CO3. The thermal hysteresis effect was minimized at the composition of 2.5 wt.% Li2CO3. It was demonstrated that by changing the composition and sintering schedule, the theoretical density of CaZr4(PO4)6 could be reached through liquid phase sintering and the thermal expansion characteristics can be engineered as desired by controlling its composition and sintering schedule.

Abstract

Lipase-catalyzed transesterification of tricaprylin with conjugated linoleic acid (CLA) ethyl ester was performed to produce triacylglycerols containing conjugated linoleic acid. Six commercially available lipases, and seven solvents were screened for their ability to incorporate CLA into tricaprylin. The transesterification reaction was performed by incubating a 1:2 mole ratio of tricaprylin and CLA ethyl ester in 3 ml solvents at 55°C, and the products were analyzed by gas chromatography. Three lipases, Novozym 435, Lipozym IM and lipase PS-C were chosen to allow a comparison of transesterification activity in our model reaction. The highest CLA incorporation with Novozym 435 and Lipozym IM was achieved in hexane while isooctane produced the highest CLA incorporation with lipase PS-C. Lipase PS-C gave higher CLA incorporation into tricaprylin when fatty acid was used as the acyl donor than other lipases did. Lipozym IM and lipase PS-C had not restrict specificity to sn-1, 3 positions, even though they had high specificity at sn-1, 3 positions. Novozym 435 among lipases tested was the most effective on the incorporation of CLA into tricaprylin.

Part of the neutrino events collected in 1994-1995 by the CHORUS experiment has been analysed. A search was performed for ντ charged current interactions followed by the τ lepton decay into a single charged negative hadron, a possible indication for νμ→ντ oscillation. A sample of 6844 events without an identified muon has been located in the emulsion target. Within the selection criteria, no τ− candidate has been found. Combining this result with the one from the search for ντ interactions using the muonic decay mode (36 182 events with an identified muon), a 90% C.L. limit on the mixing angle sin22θμτ

Abstract

SUMMARY In a typical proton exchange membrane fuel cell (PEMFC), Nafion, i.e. a typical proton-exchange membrane, allows to permeate hydrogen and oxygen to the opposite electrode, resulting in unexpected parasitic reaction, and reduces open circuit potential (OCP) because of undesirable potential mixing. This paper investigates the influences of the anode flooding and fuel starvation on cell performance under mixed-potential conditions. A two-dimensional computational fluid dynamics model was formulated by considering direct oxidation reaction when hydrogen and oxygen molecules meet to account additional water generation in both anode and cathode catalyst layers. The present model was validated by comparing the simulated cell polarization with experimentally measured cell polarization. The authors have prepared membrane electrode assembly by the decal transfer method to precisely determine various parameters that dominate the electrode kinetics. Model validation was also conducted to clearly present the predictability of the model with different cell configurations, i.e. with and without microporous layers. Through the model, effect of the oxygen permeation coefficient of the Nafion membrane on the anode flooding was investigated. In addition, reverse-current generation was predicted with different anode saturations and oxygen permeation coefficients to provide a detailed explanation on their relationship.

Abstract

The relative branching fraction RK = Γ(D0 → K−μ+v)/Γ(D0 → μ−X) has been measured by Fermilab experiment E653, using D0 mesons produced by 600 GeV π−. The semimuonic decay sample of 232 events was identified by the decay chain D ∗+ → D 0 π + , D 0 → μ + h − X , where h is a hadron. The Kμv component was extracted from the joint distribution of these events in the D0 decay variables Mmin and pTh. We find RK = 0.472 ± 0.051 (stat) ± 0.040 (sys), and use a world average of the D0 → Klv branching fraction to obtain the D0 inclusive semimuonic branching fraction B(D0 → μ+X) = (7.67 ± 1.13)%.

Abstract

A search for charm production in the coherent diffractive dissociation reaction pSi→XSi was carried out for the modes D0→K−π+, D0→K−π+π+π−, and D+→K−π+π+. No charm signals were observed, and the 90% confidence level upper limit for coherent charm pair production was determined to be 26 μb per silicon nucleus. The results are interpreted as an upper limit of 0.2% on the amount of intrinsic charm in the proton.

The five-prong vertices yield the result B ( D S + → η ′ μ + ν ) / B ( D S + → φμ + ν )

Abstract

We present a study of the Cabibbo-allowed semimuonic decay modes of the DS+ produced in 600 GeV c π − -emulsion interactions. From a signal of 18.7±4.9−0.7+0.4 events in the DS+ → oμ+υ channel, the product of production cross section and partial width is measured with respect to that for D + → K ∗0 μ + υ to be ( σ(D S + ) σ(D + )) . (Λ(D S + → oμ + ν)Λ(D + → K ∗0 μ + ν)) = 0.56 ± 0.14 ± 0.12. The form factor ratios in the decay, obtained by fitting to the decay angles and q2, are A 2 (0) 1 (0) = 2.1 −0.5 +0.6 ± 0.2 and V (0) A 1 (0) = 2.3 −0.9 +1.1 ± 0.4 , where A1 (0) and A2 (0) are the axial vector form factors and V(0) is the vector form factor, evaluated at q2 = 0. The first observation of DS+ → (ημ+υ + η'μ+υ) is also reported, and Γ (D S + → (ημ + υ + η'μ + υ)) Γ (D S + → oμ + υ) is determined to be 3.9 ± 1.6.

Abstract

The branching ratio for the decay mode D + → K ∗0 μ + ν has been measured with two methods. The first uses D0→K−μ+ν for normalization, and yields the result B( D + → K ∗0 μ + ν)=(3.25±0.71±0.75)% . From this method we also obtain the direct measurement Γ( D + → K ∗0 μ + ν)/Γ( D 0 → K − μ + ν)=0.43±0.09±0.09 . The second method uses the mode D+→K−π+π+ for normalization and yields B( D + → K ∗0 μ + ν)=(4.18±0.66±0.96)% . Combining the results of the two methods yields B( D + → K ∗0 μ + ν)=(3.57±0.96)% .

Abstract

We present total and differential cross sections for charm mesons produced in 600 GeV/c π- emulsion interactions. Fits to d2σ/dxF dpT2∞ (1−|xF|)nexp (-bpT2) for 676 electronically reconstructed D mesons with xF>0 give n=4.25±0.24 (stat.)±0.23 (syst.) and b=0.76±0.03±0.03 (GeV/c)-2. The total inclusive D+ and D0 cross sections are σ(π-N→D±; xF>0) = 8.66±0.46±1.96μb nucleon and σ(π - N→D 0 D 0 ; x F >0)=22.05±1.37±4.82μb nucleonk, where a linear dependence on the mean atomic weight of the target is assumed. These results are compared to next-to-leading order QCD predictions.

Abstract

A measurement of the form factor ratios in the decay D + → K ∗ (892) 0 μ + ν is obtained by fitting to the decay angles and q2 of 305 events. The results, evaluated at q2 = 0, are A2(0)/A1(0) = 0.82+0.22−0.23 (stat.)±0.11 (sys.) and V(0)/A1(0) = 2.00+0.34−0.32±0.16, where A1 and A2 are the axial vector form factors and V is the vector form factor. The corresponding ratio of the longitudinal to transverse polarization of the K ∗0 is 1.18±0.18±0.08. These results are compared with other experimental results and with theoretical predictions.

Abstract

Nanoparticles were produced on polyimide (PI) film through oxidation of a Ni/sub 80/Fe/sub 20/ thin film on a PI precursor layer during its imidization reaction. Film properties were investigated through transmission electron microscopy, electron diffraction and X-ray photoemission spectroscopy. The size and shape of embedded and exposed particles were compared and it was verified that the exposed particles can be effectively used as a growth template for nano-sized structures.

Abstract

Summary form only given. The pinned electrode of the exchange biased magnetic tunneling junction (MTJ), consisting of Ta/NiFe/IrMn/CoFe/AlO/sub x//Ta layer was annealed at 300/spl deg/C under vacuum to study the extent of interdiffusion within the pinned electrode. In addition, the tunnel barrier layer, AlO/sub x/ was deliberately under- and over-oxidized in the oxygen plasma in order to elucidate the effects of plasma oxidation on the interdiffusion within the thin film stack. A significant amount of Mn diffusion into the AlO/sub x/ layer was observed in the over-oxidized electrode from the compositional depth profiling using Auger Electron Spectroscopy (AES) while the under-oxidized electrode exhibited a minimal amount of Mn diffusion after annealing at 300/spl deg/C. Further interfacial analysis using X-ray Photoelectron Spectroscopy (XPS) proved that the Mn found at the CoFe/AlO/sub x/ interface in the over-oxidized electrode was in the form of MnO/sub 2/ while the Co in the CoFe layer remained unoxidized.

Abstract

As an extension to their formulation of the compliant control problem employing the framework of constrained Hamiltonian systems the authors consider the feedback of error signals with respect to a desired position, velocity and force. They allow for uncertainty in modeling and disturbances. They show that the nonlinear feedback controls introduced specify the dynamics of the manipulator on the constraint surface. Results of computer simulations which verify the analytical formulation , are presented. >

Abstract

A mono-layer of γ-Fe2O3 nanoparticles embedded in a polyimide (PI) matrix was fabricated by oxidizing Fe metal film between two PI precursor layers. There was a critical Fe thickness (∼7 nm) above which a continuous layer of γ-Fe2O3 film was formed in the PI film. Below the critical Fe thickness, the oxide film broke up into fine particles whose size was ∼10 nm with narrow size distribution. This method offers a unique way of covering a large surface area with fine magnetic oxide nanoparticles for a potential application in high-density data storage media.

Abstract

The 4-bp deletion in codons 41/42 (-TTCT) in the beta-globin gene is a common mutation that causes beta-thalassemia in Chinese. A simple method, which involved PCR amplification of the relevant region, was used for the antenatal diagnosis of a fetus at risk for this mutation. The fetal PCR product showed a single fragment of normal size on MetaPhor gel. The homozygous normal status was further confirmed by the generation of heteroduplexes only after addition of homozygous mutant DNA.

Abstract

The OPERA neutrino detector in the underground Gran Sasso Laboratory (LNGS) was designed to perform the first detection of neutrino oscillations in appearance mode through the study of νμ→ ντ oscillations. The apparatus consists of an emulsion/lead target complemented by electronic detectors and it is placed in the high energy long-baseline CERN to LNGS beam (CNGS) 730 km away from the neutrino source. Runs with CNGS neutrinos were successfully carried out in 2007 and 2008 with the detector fully operational with its related facilities for the emulsion handling and analysis. After a brief description of the beam and of the experimental setup we report on the collection, reconstruction and analysis procedures of first samples of neutrino interaction events. © 2009 IOP Publishing Ltd and SISSA., 0, P06020, SCOPUS: ar.j, info:eu-repo/semantics/published

Abstract

The OPERA neutrino oscillation experiment has been designed to prove the appearance of ντ in a nearly pure νμ beam (CNGS) produced at CERN and detected in the underground Hall C of the Gran Sasso Laboratory, 730 km away from the source. In OPERA, τ leptons resulting from the interaction of ντ are produced in target units called bricks made of nuclear emulsion films interleaved with lead plates. The OPERA target contains 150000 of such bricks, for a total mass of 1.25 kton, arranged into walls interleaved with plastic scintillator strips. The detector is split into two identical supermodules, each supermodule containing a target section followed by a magnetic spectrometer for momentum and charge measurement of penetrating particles. Real time information from the scintillators and the spectrometers provide the identification of the bricks where the neutrino interactions occurred. The candidate bricks are extracted from the walls and, after X-ray marking and an exposure to cosmic rays for alignment, their emulsion films are developed and sent to the emulsion scanning laboratories to perform the accurate scan of the event. In this paper, we review the design and construction of the detector and of its related infrastructures, and report on some technical performances of the various components. The construction of the detector started in 2003 and it was completed in Summer 2008. The experiment is presently in the data taking phase. The whole sequence of operations has proven to be successful, from triggering to brick selection, development, scanning and event analysis. © 2009 IOP Publishing Ltd and SISSA., 0, P04018, SCOPUS: ar.j, info:eu-repo/semantics/published

Abstract

The OPERA neutrino oscillation experiment is based on the use of the Emulsion Cloud Chamber (ECC). In the OPERA ECC, nuclear emulsion films acting as very high precision tracking detectors are interleaved with lead plates providing a massive target for neutrino interactions. We report on studies related to the effects occurring from the contact between emulsion and lead. A low radioactivity lead is required in order to minimize the number of background tracks in emulsions and to achieve the required performance in the reconstruction of neutrino events. It was observed that adding other chemical elements to the lead, in order to improve the mechanical properties, may significantly increase the level of radioactivity on the emulsions. A detailed study was made in order to choose a lead alloy with good mechanical properties and an appropriate packing technique so as to have a low enough effective radioactivity., Comment: 19 pages, 11 figures
