Re-Conceptualizing Expository Language as Narration
Authors: Petersen Douglas B. , Petersen Jeffrey W.
Published: August 2016

There is the very real possibility that narrative-based language intervention may not only improve narrative-specific outcomes such as narrative retelling and personal story generation, but also expository language, which has traditionally been perceived as a dissimilar, distal outcome. In this paper we discuss the relationship between narrative language and expository language, propose that apprehending the elements that are essential to good narration is not only helpful for the production and comprehension of expository language, but is in a sense, even required. We also discuss how narrative intervention, when properly shaped, can logically lead to growth in expository language.

Authors: Gillam Sandra , Holbrook Sarai Sophia , Westenskow Arla
Published: August 2016

Children with language impairment (LI) exhibit difficulty with basic information processing skills that relate to encoding, storing, recalling, organizing, and producing language (Reimann, Gut, Frischknecht, & Grob, 2013). These language-learning problems may impact their ability to understand and use discourse in social and academic settings. One form of informational discourse that is not often discussed, but is critical for success in academic settings, is mathematical discourse. This paper addresses ways in which SLPs may improve students' abilities to profit from instruction in math.
Harmonic currents compensator GCI at the microgrid
Authors: Mohd Zin A.A. , Naderipour A. , Hafiz Habibuddin M. , Guerrero J.M.
Published: August 2016

The main challenge associated with the grid‐connected inverter (GCI) in distributed generation systems is keeping the harmonic content of the output current below the specified value and compensating for unbalanced loads even when the grid is subject to disturbances such as harmonic distortion and unbalanced loads. To overcome these challenges, a current control strategy for a three‐phase GCI under unbalanced and nonlinear load conditions is presented. The proposed control method enables the GCI to inject balanced and clean currents to the grid even when the local loads are unbalanced and/or nonlinear; it also compensates for the harmonic currents and controls the active and reactive powers. The main advantage and objective of this method is to effectively compensate for the harmonic current content of the grid current and microgrid without the use of any compensation devices such as active, passive and LCL filters.
Design of cryptographically secure AES like S‐Box using second‐order reversible cellular automata for wireless body area network applications
Authors: Gangadari Bhoopal Rao , Rafi Ahamed Shaik
Published: August 2016

In biomedical, data security is the most expensive resource for wireless body area network applications. Cryptographic algorithms are used in order to protect the information against unauthorised access. Advanced encryption standard (AES) cryptographic algorithm plays a vital role in telemedicine applications. The authors propose a novel approach for design of substitution bytes (S‐Box) using second‐order reversible one‐dimensional cellular automata (RCA2) as a replacement to the classical look‐up‐table (LUT) based S‐Box used in AES algorithm. The performance of proposed RCA2 based S‐Box and conventional LUT based S‐Box is evaluated in terms of security using the cryptographic properties such as the nonlinearity, correlation immunity bias, strict avalanche criteria and entropy. Moreover, it is also shown that RCA2 based S‐Boxes are dynamic in nature, invertible and provide high level of security. Further, it is also found that the RCA2 based S‐Box have comparatively better performance than that of conventional LUT based S‐Box.
Transmission lines differential protection based on an alternative incremental complex power alpha plane
Authors: Almeida Maria Leonor S. , Silva Kleber M.
Published: August 2016

This study proposes a new concept of transmission line differential protection based on an alternative alpha plane of incremental complex power, where the restraint characteristic is simply defined as its left‐half‐plane, so that no settings are required to define it. As the incremental complex power is evaluated per phase, the proposed algorithm is inherently phase segregated, not requiring additional faulted phase selection logics. A simple harmonic restraint strategy along with an external fault detection logic provides security for external faults with current transformer saturation. Aiming to evaluate the performance of the proposed algorithm, a wide variety of fault scenarios are simulated for a 500 kV transmission line 200 km long using the Alternative Transients Program. The obtained results reveal the proposed algorithm provides a fast and reliable line protection, being robust against variations in fault parameters, sources strength and loading conditions, as well as power swing situations and line energisation manoeuvres. Accordingly, one can suppose the proposed algorithm might be successfully used in numerical transmission line relaying.
Multi‐contingency TSCOPF based on full‐system simulation
Authors: Ledesma Pablo , Calle Ignacio Antonio , Castronuovo Edgardo Daniel , Arredondo Francisco
Published: August 2016

Transient stability constrained optimal power flow (TSCOPF) is a non‐linear optimisation problem used to perform economic dispatches while ensuring TS. This study proposes a multi‐contingency TSCOPF model that retains the dynamics of all generators and includes a transient synchronous generator fourth‐order dq ‐axis model. A program is developed that automatically reads the system data from standard files, builds the multiple‐contingency TSCOPF model on a high‐level modelling system and solves it using a non‐heuristic interior point algorithm. This approach facilitates the application of the model to a variety of systems and scenarios. A TSC based on the speed deviation instead of the rotor angle is proposed. Results obtained on several standard systems are shown. The proposed method is applied to the northwest Spanish transmission system to obtain an optimised dispatch that ensures TS after any of a number of faults, and to assess the economic impact of fault‐clearing times at different substations.
Islanding detection method for microgrid based on extracted features from differential transient rate of change of frequency
Authors: Hashemi Farid , Mohammadi Mohammad , Kargarian Amin
Published: August 2016

One of the most important challenges in microgrid operation is the unintentional islanding occurrence. Unintentional islanding can cause serious safety hazards and technical issues. Islanding detection methods can be classified into active and passive methods. The main disadvantages of the passive methods are large non‐detection zone as well as determination of suitable threshold value to avoid unwanted distributed generations tripping in normal network events. In order to overcome these drawbacks, this study proposes a novel, fast, and reliable method to identify islanding conditions. The proposed method calculates different transient states in the rate of change of frequency signal in two consecutive cycles. Various features of the differential signal are extracted. The extracted feature vectors associated with different operation conditions such as islanding and non‐islanding events are used to train artificial neural networks (ANNs). The performances of different structures of ANNs and also other machine learning methods such as support vector machine and adaptive neuro fuzzy inference system are evaluated for islanding detection purposes. The simulation results indicate that the proposed method provides more accurate and faster responses compared with other conventional islanding detection methods.
Power quality improvement using bridgeless‐Landsman converter for LED driver
Authors: Jha Aman , Singh Bhim
Published: August 2016

This study presents a bridgeless‐Landsman converter for power factor correction (PFC) of light‐emitting diode (LED) driver. It is targeted for high brightness LED driver with pulse‐width modulation dimming for brightness control. This PFC converter is used to feed dual output flyback DC–DC converter which supplies power to the LED module and forced cooling unit with galvanic isolation. The brightness control of LED is performed by three independent synchronous buck converters. The PFC converter is designed to operate in discontinuous input inductor current mode for inherent PFC at universal AC mains. A prototype of the proposed PFC LED driver is developed to validate experimentally the design and model. The power quality indices of the proposed LED driver are evaluated at rated and light load conditions for universal AC mains (90–265 V) with brightness control. The power quality indices are found within acceptable range of international harmonic standard IEC 61000‐3‐2 for universal AC mains.
Bridgeless single‐phase step‐down PFC converter
Authors: Malekanehrad Mahdi , Adib Ehsan
Published: August 2016

This study presents a bridgeless single‐phase step‐down power factor correction (PFC) converter. The proposed converter consists of a buck converter in positive half‐line cycle and a flyback converter in the negative one. The dead angle of input line current is omitted so high power factor (PF) and low total harmonic distortion (THD) are obtained. There are just two simultaneously conducting semiconductor devices in the charging path of buck and flyback inductors that reduce the conduction losses. A 80 W, 24 V experimental prototype verifies the operation of the proposed rectifier and a PF of 0.995 and THD <10% can be achieved.
Reception and calibration of bistatic SF ISAR imaging system with wideband receiver
Authors: Xiong Di , Zhang Xiongkui , Wang Junling , Zhao Huipeng , Gao Meiguo
Published: August 2016

The reception and calibration of bistatic stepped‐frequency (SF) inverse synthetic aperture radar (ISAR) imaging system with wideband receiver are studied in this study. First, as residual carrier frequency offset and over‐sampling will be introduced in the SF linear frequency modulation signal which is received by wideband receiver, a spectrum truncation, and frequency error compensation method is proposed to solve the problems. Second, a calibration method of bistatic SF ISAR imaging system based on accumulated spherical satellite echoes is proposed, since echo signals are modulated by non‐ideal amplitude and phase characteristics of radar system channels, which seriously deteriorates the quality of SF imaging result. Theoretical analysis and simulation results indicate that the proposed method can effectively compensate the non‐ideal characteristics of radar system channels.

The smooth impact drive mechanism (SIDM) actuator is traditionally excited by a saw-tooth wave, but it requires large input voltages for high-speed operation and load capacity. To improve the output characteristic of the SIDM operating at low input voltage, a novel driving method based on ultrasonic friction reduction technology is proposed in this paper. A micro-amplitude sinusoidal signal with high frequency is applied to the rapid deformation stage of the traditional saw-tooth wave. The proposed driving method can be realized by a composite waveform that includes a driving wave (D-wave) and a friction regulation wave (FR-wave). The driving principle enables lower input voltage to be used in normal operation, and the principle of the proposed driving method is analyzed. A prototype of the SIDM is fabricated, and its experimental system is established. The tested results indicate that the actuator has suitable velocity and load characteristics while operating at lower input voltage, and the load capacity of the actuator is 2.4 times that of an actuator excited by a traditional saw-tooth driving wave.

The C-2U experiment at Tri Alpha Energy studies the evolution of field-reversed configuration (FRC) plasmas sustained by neutral beam injection. Data on the FRC plasma performance are provided by a comprehensive suite of diagnostics that includes magnetic sensors, interferometry, Thomson scattering, spectroscopy, bolometry, reflectometry, neutral particle analyzers, and fusion product detectors. While many of these diagnostic systems were inherited from the preceding experiment C-2, C-2U has a variety of new and upgraded diagnostic systems: multi-chord far-infrared polarimetry, multiple fast imaging cameras with selectable atomic line filters, proton detector arrays, and 100 channel bolometer units capable of observing multiple regions of the spectrum simultaneously. In addition, extensive ongoing work focuses on advanced methods of measuring separatrix shape and plasma current profile that will facilitate equilibrium reconstruction and active control of the FRC plasma.

We present a crossed molecular beam scattering study, using velocity-map ion-imaging detection, of state-to-state rotational energy transfer for NO(A2Σ+) in collisions with the kinematically identical colliders He and D2. We report differential cross sections and angle-resolved rotational angular momentum polarization moments for transfer of NO(A, v = 0, N = 0, j = 0.5) to NO(A, v = 0, N′ = 3, 5-12) in collisions with He and D2 at respective average collision energies of 670 cm−1 and 663 cm−1. Quantum scattering calculations on a literature ab initio potential energy surface for NO(A)-He [J. Kłos et al., J. Chem. Phys. 129, 244303 (2008)] yield near-quantitative agreement with the experimental differential scattering cross sections and good agreement with the rotational polarization moments. This confirms that the Kłos et al. potential is accurate within the experimental collisional energy range. Comparison of the experimental results for NO(A) + D2 and He collisions provides information on the hitherto unknown NO(A)-D2 potential energy surface. The similarities in the measured scattering dynamics of NO(A) imply that the general form of the NO(A)-D2 potential must be similar to that calculated for NO(A)-He. A consistent trend for the rotational rainbow maximum in the differential cross sections for NO(A) + D2 to peak at more forward angles than those for NO(A) + He is consistent with the NO(A)-D2 potential being more anisotropic with respect to NO(A) orientation. No evidence is found in the experimental measurements for coincident rotational excitation of the D2, consistent with the potential having low anisotropy with respect to D2. The NO(A) + He polarization moments deviate systematically from the predictions of a hard-shell, kinematic-apse scattering model, with larger deviations as N′ increases, which we attribute to the shallow gradient of the anisotropic repulsive NO(A)-He potential energy surface.
Passive nanofluidic diode using non-uniform nanochannels
Authors: Mo Jingwen , Li Chu , Li Long , Wang Jun , Li Zhigang
Published: August 2016

In this work, we propose a nanofluidic diode for simple fluids using non-uniform nanochannels. Molecular dynamics simulations show that the fluidic diode allows water flows in the forward direction and blocks flows in the backward direction in a wide range of pressure drops. The unidirectional water flows are owing to the distinct activation pressures in different directions. In the forward (converging) direction, the activation pressure is small because of the relatively low capillary pressure and the water coalescence at the exit. In the backward direction, the activation pressure is high due to the high infiltration pressure. The pressure drop range for the fluidic diode can be varied by modifying the surface wettability, channel height, and/or the tilt angle of the channel. The fluidic diode can be used for flow control in integrated micro- and nanofluidic devices.

A non-destructive diagnostic method for the characterization of circularly polarized, ultraintense, short wavelength free-electron laser (FEL) light is presented. The recently installed Delta undulator at the LCLS (Linac Coherent Light Source) at SLAC National Accelerator Laboratory (USA) was used as showcase for this diagnostic scheme. By applying a combined two-color, multi-photon experiment with polarization control, the degree of circular polarization of the Delta undulator has been determined. Towards this goal, an oriented electronic state in the continuum was created by non-resonant ionization of the O2 1s core shell with circularly polarized FEL pulses at hν ≃ 700 eV. An also circularly polarized, highly intense UV laser pulse with hν ≃ 3.1 eV was temporally and spatially overlapped, causing the photoelectrons to redistribute into so-called sidebands that are energetically separated by the photon energy of the UV laser. By determining the circular dichroism of these redistributed electrons using angle resolving electron spectroscopy and modeling the results with the strong-field approximation, this scheme allows to unambiguously determine the absolute degree of circular polarization of any pulsed, ultraintense XUV or X-ray laser source.

We investigated the crystallographic structure of FePS3 with a layered structure using transmission electron microscopy and powder X-ray diffraction. We found that FePS3 forms a rotational twin structure with the common axis along the c*-axis. The high-resolution transmission electron microscopy images revealed that the twin boundaries were positioned at the van der Waals gaps between the layers. The narrow bands of dark contrast were observed in the bright-field transmission electron microscopy images below the antiferromagnetic transition temperature, TN ≈ 120 K. Low-temperature X-ray diffraction showed a lattice distortion; the a- and b-axes shortened and lengthened, respectively, as the temperature decreased below TN. We propose that the narrow bands of dark contrast observed in the bright-field transmission electron microscopy images are caused by the directional lattice distortion with respect to each micro-twin variant in the antiferromagnetic phase.
Multi-field plasma sandpile model in tokamaks and applications

Published: August 2016

A multi-field sandpile model of tokamak plasmas is formulated for the first time to simulate the dynamic process with interaction between avalanche events on the fast/micro time-scale and diffusive transports on the slow/macro time-scale. The main characteristics of the model are that both particle and energy avalanches of sand grains are taken into account simultaneously. New redistribution rules of a sand-relaxing process are defined according to the transport properties of special turbulence which allows the uphill particle transport. Applying the model, we first simulate the steady-state plasma profile self-sustained by drift wave turbulences in the Ohmic discharge of a tokamak. A scaling law as f=aq0b+c for the relation of both center-density n(0) and electron (ion) temperatures Te(0)(Ti(0)) with the center-safety-factor q0 is found. Then interesting work about the nonlocal transport phenomenon observed in tokamak experiments proceeds. It is found that the core electron temperature increases rapidly in response to the edge cold pulse and inversely it decreases in response to the edge heat pulse. The results show that the nonlocal response of core electron temperature depending on the amplitudes of background plasma density and temperature is more remarkable in a range of gas injection rate. Analyses indicate that the avalanche transport caused by plasma drift instabilities with thresholds is a possible physical mechanism for the nonlocal transport in tokamaks. It is believed that the model is capable of being applied to more extensive questions occurring in the transport field.

This paper demonstrates the facile synthesis of high performance silver-polypyrrole-multiwall carbon nanotubes (Ag-PPy-FMWCNTS) nanocomposites via electrodeposition method on stainless steel substrate and its application as a low cost counter electrode (CE) for the precious platinum (Pt) free DSSC. The nanocomposites were characterized by variety of techniques such as Fourier transforms infrared (FTIR), X-ray diffraction, Scanning electron microscope (SEM), cyclic voltammetry (CV) and Four probe technique respectively. The cyclic voltammetry and Tafel polymerization measurements of Ag-PPy-FMWCNTS nanocomposites CE reveal the favorable electrocatalytic activity and low charge transfer resistance Rct(2.50 Ω cm2) for I3−/I− redox solution. The four probe studies showed the large electrical conductivity (226S cm−1) of Ag-PPy-FMWCNTS nanocomposite. The DSSC assembled with Ag-PPy-FMWCNTS nanocomposites CE display the considerable short circuit current density (13.95 mA cm−2) and acceptable solar to electrical conversion efficiency of 7.6%, which is higher to the efficiency of DSSC with thermally decomposed Pt reference electrode 7.1%. The excellent conversion efficiency, rapid charge transfer in combination with low cost and simple fabrication method of Ag-PPy-FMWCNTS nanocomposites can be exploited as an efficient and potential candidate to replace the Pt CE for large scale production of DSSC.
Self-consistent non-stationary theory of the gyrotron
Authors: Dumbrajs Olgierd , Nusinovich Gregory S.
Published: August 2016

For a long time, the gyrotron theory was developed assuming that the transit time of electrons through the interaction space is much shorter than the cavity fill time. Correspondingly, it was assumed that during this transit time, the amplitude of microwave oscillations remains constant. A recent interest to such additional effects as the after-cavity interaction between electrons and the outgoing wave in the output waveguide had stimulated some studies of the beam-wave interaction processes over much longer distances than a regular part of the waveguide which serves as a cavity in gyrotrons. Correspondingly, it turned out that the gyrotron theory free from the assumption about constant amplitude of microwave oscillations during the electron transit time should be developed. The present paper contains some results obtained in the framework of such theory. The main attention is paid to modification of the boundary between the regions of oscillations with constant amplitude and automodulation in the plane of normalized parameters characterizing the external magnetic field and the beam current. It is shown that the theory free from the assumption about the frozen wave amplitude during the electron transit time predicts some widening of the region of automodulation.
