MODELING HIGH-VELOCITY QSO ABSORBERS WITH PHOTOIONIZED MAGNETOHYDRODYNAMIC DISK WINDS

We extend our modeling of the ionization structure of magnetohydrodynamic (MHD) accretion-disk winds, previously applied to Seyfert galaxies, to a population of quasi-stellar objects (QSOs) of much lower X-ray-to-UV flux ratios, i.e., smaller αox index, motivated by UV/X-ray ionized absorbers with extremely high outflow velocities in UV-luminous QSOs. We demonstrate that magnetically driven winds ionized by a spectrum with αox ≃ −2 can produce the charge states responsible for C iv and Fe xxv/Fe xxvi absorption in wind regions with corresponding maximum velocities of v(C iv) ≲0.1c and v(Fe xxv) ≲ 0.6c (where c is the speed of light) and column densities NH ∼ 1023–1024 cm−2, in general agreement with observations. In contrast to the conventional radiation-driven wind models, high-velocity flows are always present in our MHD-driven winds but manifest in the absorption spectra only for αox ≲ −2, as larger αox values ionize the wind completely out to radii too large to demonstrate the presence of these high velocities. We thus predict increasing velocities of these ionized absorbers with decreasing (steeper) αox, a quantity that emerges as the defining parameter in the kinematics of the active galactic nucleus UV/X-ray absorbers.
Synthesis and Characterization of Nanosize Polyanthranillic Acid for Solid Polymer Electrolyte

Article history: Received 20 March 2019 Accepted 29 April 2019 Available online 05 June 2019 Conducting polymer of anthranilic acid (PANA) has been synthesized through emulsion polymerization technique. Emulsion polymerization helps in slowing down kinetics of polymerization in comparison to one-phase polymerization and thereby induces formation of monodispersed. Reaction progress of conducting polymer formation is studied by UV–Vis and FTIR spectroscopy. Morphology of PANA is characterized by XRD, TEM, AFM and electrochemical techniques. XRD of conducting polymer depicts the less crystalline nature of polymer with crystallite size of 75 nm. Voltammetry has shown the electroactive nature of PANA. The performance of energy storage devices including pseudocapacitors is evaluated mostly by measuring energy density and power density.
Tin-bronze cladding on thin steel sheet by cold metal transfer arc deposition

ABSTRACT Tin bronze cladding layer with thin thickness and large width was fabricated on thin steel sheet by cold metal transfer arc deposited technique. The morphology, microstructure and mechanical properties of both cladding layer and thin steel sheet were investigated. It was found that the cladding layer had no gas holes, cracks, oxide particles and iron-rich phase. The thickness of diffusion layer at tin bronze/steel interface was only 3–4 µm and the dilution rate of the cladding layer was almost zero. The strength and hardness of the thin steel sheet after arc deposited process were enhanced.
A Low Power Low Supply MOS-Only Subthreshold Voltage Reference for Wide Temperature Range

A Sub-1V, MOS-only Voltage Reference Circuit (VRC) has been proposed with the utmost of transistors working as subthreshold region for low-supply and low-power applications. A supply-insensitive current is passed to Active Load Circuit (ALC) for supply and temperature independence at the output reference voltage. It has four current mirrors connected in a closed loop configuration to generate a supply-independent current which is passed through the ALC resulting supply and temperature insensitive output reference voltage. The ALC has a combination of two subthreshold NMOS transistors having different threshold voltages. The presented VRC is simulated using standard 90 nm CMOS model for 0.25-1 V supply voltage range. The simulation result gives minimum operating voltage required as 0.25 V for which all transistors work in their respective region of operation. For the supply range of 0.25-1 V, the obtained mean voltage reference is 100.4 mV with the line regulation of 0.186 mV/V. The temperature coefficient (TC) of 51ppm/°C is achieved for a wide temperature range of -50 to 135°C with the given minimal operating supply voltage. The power dissipation for minimal supply voltage at room temperature is 33 nW. The proposed VRC exhibits a high PSRR of -52.5 dB at 100Hz and -29 dB at 1 MHz.

NUMERICAL ANALYSIS TO EVALUATE THE EFFECT OF RESTRAINED EDGE DISTANCE ON EARLY AGE CRACKING DUE TO DRYING SHRINKAGE

Drying shrinkage can be defined as the reduction of volume that concrete undergoes as a result of the moisture relocation when exposed to a lower relative moist surrounding environment than the foremost one of its basic pore structure system. Finite element model(FEM) is developed and implemented, to simulate and analyses the early age restrained cracking behavior due to drying shrinkage. The Simulation focus on the evaluation of the impact of restrained edge distance on early age cracking due to deformation resulting from drying shrinkage. The FEM analysis Model deals with phenomena of temperature, humidity exchange, thermal diffusion, and mechanical behavior which can take a place at the three first days followed the concrete casting, to evaluate the diameter, distance effects on the early age crack. The effect of the diameter of the restricted steel ring was studied on the diameter of the concrete and the spacing between them. The results were compared with the results of the experiments discussed in the published literature; it was found that there is an excellent agreement for all the performed analysis.
An Experimental Investigation To Develop A Non-membrane Salinity Gradient Power Configuration

Salinity Gradient power (SGP) has been identified as a clean energy resource with a potential of producing 1.7 to 2.8 TW worldwide. Development of a feasible SGP would allow it to be used when two bodies of water have different salinity levels as well as being combined with other alternate renewable energy sources or use the otherwise waste discharge of desalination plants and fracking sites. Two SGP methods, reverse electrodialysis (RED) and pressure retarded osmosis (PRO) that use membranes to harness into electrical power, have been demonstrated on a pilot plant level. CapMix techniques use electrodes to store charge in the surfaces’ electric double layer (EDL). Energy is stored in an expanding EDL in a high concentration solution and energy is released when the EDL compresses in a low concentration solution. An experimental investigation to develop a benchtop salinity gradient device is described. Both CapMix and BatMix techniques have been demonstrated in batch mode operation and no reported results with continuous power output have been documented. A benchtop apparatus was designed and BatMix and CapMix (CDLE) techniques were attempted to be duplicated. Cell potential during the charging of the BatMix was consistent with literature reports. BatMix High concentration cell potential dropped when it was expected to increase and increased during the discharge phase when it was expected to decrease. The reason for this behavior could not be explained. Current ranges were in the order of nano amperes against the reported range of milliamperes in literature. This is assumed to be due to the high internal resistance of the electrode cell assembly. In the CapMix technique, cell potential during the cycle remained consistently below the literature reported levels. The current ranges also reported in the
Confined van der Waals Epitaxial Growth of Two-Dimensional Large Single-Crystal In2Se3 for Flexible Broadband Photodetectors

The controllable growth of two-dimensional (2D) semiconductors with large domain sizes and high quality is much needed in order to reduce the detrimental effect of grain boundaries on device performance but has proven to be challenging. Here, we analyze the precursor concentration on the substrate surface which significantly influences nucleation density in a vapor deposition growth process and design a confined micro-reactor to grow 2D In2Se3 with large domain sizes and high quality. The uniqueness of this confined micro-reactor is that its size is ~102-103 times smaller than that of a conventional reactor. Such a remarkably small reactor causes a very low precursor concentration on the substrate surface, which reduces nucleation density and leads to the growth of 2D In2Se3 grains with sizes larger than 200 μm. Our experimental results show large domain sizes of the 2D In2Se3 with high crystallinity. The flexible broadband photodetectors based on the as-grown In2Se3 show rise and decay times of 140 ms and 25 ms, efficient response (5.6 A/W), excellent detectivity (7×1010 Jones), high external quantum efficiency (251%), good flexibility, and high stability. This study, in principle, provides an effective strategy for the controllable growth of high quality 2D materials with few grain boundaries.
KEYPHRASE EXTRACTION FROM SCIENTIFIC LITERATURE USING JOINT GEOMETRIC GRAPH EMBEDDING MATCHING by JUSTIN PAYAN

Keyphrase extraction is the task of selecting representative words and phrases from a document. Recent research has focused on keyphrase extraction via graph-theoretic approaches, which leverage various graph-based centrality measures to locate important nodes in a constructed keyphrase candidate graph. In this thesis, we propose the use of an inexact graph matching algorithm for keyphrase extraction. We match graphs derived from test documents with graphs that have labeled keyphrases, and label as keyphrases the test nodes matching with known keyphrases. Our graph matching keyphrase extraction algorithm obtains an F-score of 14.6% on the standard SemEval 2010 Task 5 dataset and 37.1% on the well-known Inspec dataset. These scores are in line with time-tested algorithms on both datasets. We therefore conclude that inexact graph matching algorithms can be applied to keyphrase extraction successfully.

Detection of Atrial Fibrillation using Autoregressive modeling

A ‎ atrial fibrillation (AF) is the arrhythmia that commonly causes death in the adults. We measured AR coefficients using Burg’s method for each 15 second segment of ECG. These features are classified using the different statistical classifiers: kernel SVM and KNN classifier. The performance of the algorithm was evaluated on signals from MIT Physionet database. The effect of AR model order and data length was tested on the classification results. This method shows better results can be used for practical use in the clinics. ‏
Interactive query learning for isolated speech recognition

The authors propose an interactive query learning approach to isolated speech recognition tasks. The approach starts with training multiple 'one-net-one-class' time delay neural networks (TDNNs) based on sequences of LPC vectors. After all TDNNs are trained, initiated from each available LPC training sequence for one specific TDNN (say, class k), an improved network inversion algorithm with imposing constraint is used to generate a set of inverted LPC sequences corresponding to various output values of the corresponding TDNN. By carefully listening to synthesized speech based on the inverted LPC sequences, a conjugate pair of LPC sequences is selected from the whole set of LPC sequences; one corresponds to the acceptable speech of class k and the other corresponds to the unacceptable speech of class k. This conjugate LPC sequence pair constitutes some parts of the classification boundary associated with this class, and should be further used as the training date to refine the already trained classifier boundary. A 6% accuracy improvement was achieved when the proposed method was tested on speaker independent E-set data. <<ETX>>
Discursive Framing : Debates over Small Reservoirs in the Rural South

Why small reservoirs? Why the rural South? What is meant by small reservoir? Why such a specific topic? These are questions readers of this collection of essays are likely to ask. This special issue on the Policies, Politics and Realities of Small Reservoirs in the Rural South was prompted by a simple observation: since the 1980s, the questions that revolve around small reservoirs have evolved little despite continuous development and academic attention to the topic worldwide. Continuous interests and related investments in small reservoirs in the context of long-known challenges and opportunities echo an observation by Diemer and Vincent (1992) on the "failure of collective memory and collective action" and reinforces a tendency to reiterate long-known problems in the field of irrigation in Africa (Lankford, 2009). Rather than providing normative answers to questions surrounding small reservoirs, the papers in this collection help understand how this 'stabilisation' of the debate came into being. Here, small reservoirs in the rural South provide an opportunity to better understand the emergence, malleability and persistence of specific 'models' for rural development, that is, interventions which ostensibly embody a dimension of 'success' and whose shortcomings are generally downplayed and framed as mere 'externalities' associated with the context of implementation (Molle, 2008). More specifically, and in line with critical analysts of development and environmental processes, we demonstrate the importance of looking at discursive framings of past and current agricultural water management projects and policies to understand how and what they do in practice for multiple actors. Thousands of small dams dot the landscapes of the rural South (table 1); they have long attracted development and academic attention worldwide. They are known under multiple names in various regions of the world: tanks or johads in South Asia (Aubriot and Prabakhar; Gupta, this issue), açudes in Brazil (Molle, 1994), small reservoirs or micro-dams in sub-Saharan Africa (Nkhoma; Sally et al., Venot et al., this issue; Aberra, 2004), lacs collinaires in North Africa and the Middle East in general (Albergel et al., 2004) and Tunisia in particular (Selmi and Talineau, 1994), or just small dams in other regions where they are common, such as Northeast Thailand and Mexico. Defining what 'makes' a small reservoir is however not agreed upon, as criteria (size, type of infrastructure, modes of management, planning approaches, etc) and thresholds (volume, height, number of farmers, irrigated area, etc) can vary widely depending on the vantage point considered and the issues or actors at stake (see Turner, 1994 for a similar argument on small-scale irrigation). We do not embark here upon definitional debates on
Performance assessment of an earthquake-based optimally designed fluid viscous damper under blast loading

Terrorist attacks and explosion devices are one of the growing worldwide threats which seriously threaten the safety of strategic structures. The aim of this study is assessing the performance of the linear fluid viscous damper optimally designed based on seismic loading under blast loading. To this end, the control system is first optimally designed under different earthquakes and the performance of the optimally designed fluid viscous damper is evaluated under different external blast scenarios. In order to design the optimal fluid viscous damper for seismic loading, the design problem is transformed into an optimization problem that the genetic algorithm has been used to solve the optimization problem and determine the optimal values of design variables. The fluid viscous damper configuration including size and distribution has been considered as the design variables and the design objective has been defined to keep the structure behavior in the elastic range with a minimum control cost. The optimization results show that the total added optimal damping is dependent on earthquake record, while in this case study the optimal distributions of the fluid viscous damper under earthquake records are not so different. The performance assessment of the earthquake-based optimally designed fluid viscous damper under blast loading shows its effectiveness in achieving the desired design objective. Therefore, in this case study, the fluid viscous damper designed for seismic loading can be considered as a well-designed control system under multi-hazard of blast and earthquake.
Risk assessment of harmful types of plastics in the marine environment

This report presents the results of a risk assessment of residual chemical additives, monomers and degradation products present in microplastic (MP) particles in the marine environment. Seven cases of different polymer types and product groups are defined that represent the most significant exposures of MPs, and thus potential highrisk cases towards marine organisms. Risk Quotients (RQ) are calculated for three trophic levels, i.e. pelagic/planktonic zooplankton: copepod, benthopelagic fish: atlantic cod and seabird: northern fulmar. Danish Miljøkvalitetskrav (MKK) and European Environmental Quality Standard (EQS) values are used as toxicity threshold values. RQ larger than unity, which indicates potential risk, is estimated for copepod and cod (pelagic community) and the flame-retardant pentabromdiphenylether (PeBDE) used in polyurethane (PUR), the biocide tributyltin (TBT) used in polyvinylchloride (PVC) and PUR, and the flame-retardant hexabromocyclododecane (HBCD) used in expanded polystyrene (EPS). The highest estimated RQ for fulmar (secondary poisoning) is 0.1 for PeBDE used in PUR.
Self-Selection into Public Service When Corruption is Widespread: The Anomalous Russian Case

Drawing on experimental games and surveys conducted with students at two universities in Russia, we compare the behavioral, attitudinal, and demographic traits of students seeking public sector employment to the traits of their peers seeking jobs in the private sector. Contrary to similar studies conducted in other high-corruption contexts, such as India, we find evidence that students who prefer a public sector career display less willingness to cheat or bribe in experimental games as well as higher levels of altruism. However, disaggregating public sector career paths reveals distinctions between the federal civil service and other types of public sector employment, with federal government positions attracting students who exhibit some similarities with their peers aspiring to private sector careers. We discuss multiple interpretations consistent with our findings, each of which has implications for the creation of effective anti-corruption policies and for understanding of state capacity in contexts where corruption is widespread.

The Full Information Feedback in Minimum-Effort Game: An Experiment

We report an experiment designed to test for the impact of giving more information feedback about others’ choices in the previous period on coordination in a repeated minimum-effort game. We consider full and limit feedback treatments. Our results indicate that full feedback group coor- dinates at higher level of effort and more group in full feedback treatment reach equilibrium and coordination success than limit feedback group. Compared to the previous studies, we can observe the coordination outcome in the long run by repeating the game 50 times and full feedback is giving the subjects full information about others’ choices in this period and historical choices in last 10 periods in the group.
