Rotationally Symmetric Ferrofluid Flow and Heat Transfer in Porous Medium with Variable Viscosity and Viscous Dissipation

The analysis of three dimensional rotationally symmetric boundary layer flow of field dependent viscous ferrofluid saturating porous medium is performed. The fluid under consideration is electrically nonconducting incompressible magnetic fluid. The flow is generated due to the rotation of an infinite disk maintained at a uniform temperature. The momentum equations give rise to nonlinear coupled boundary value problem which is solved using Finite Difference and Newton methods. The numerical solutions for the governing nonlinear differential equations are obtained over the entire range of physical parameters. The effects of field dependent viscosity, permeability parameter, Prandtl number (Pr) and Eckert number (Ec) on various flow characteristics are discussed in detail and presented graphically. A special attention has been paid to study the effects of viscous dissipation on thermal boundary layer. Appreciable effects of these physical parameters are recorded on boundary layer displacement thickness, skin friction coefficients and rate of heat transfer.
Models in the Brain

The issues surrounding mental content that were intensely debated in the 1980’s and 90’s remained unresolved, and no new approaches have been forthcoming since. Now, intense interest in consciousness, perceptual content, concepts, and mental representation has once again brought the issue of intentionality to the fore. Models in the Brain aims to present a new naturalistic theory of intentionality that addresses these problems freshly with a much-needed injection of neuroscience, opening up the subject to empirical investigation in a new way.
Feature Transfer Learning for Wav 2 Text Sequence-to-Sequence ASR

In this paper, we construct the first end-to-end attention-based encoder-decoder model to process directly from raw speech waveform to the text transcription. We called the model as ”Attention-based Wav2Text”. To assist the training process of the end-to-end model, we propose to utilize a feature transfer learning. Experimental results also reveal that the proposed Attention-based Wav2Text model directly with raw waveform could achieve a better result in comparison with the attentional encoder-decoder model trained on standard front-end filterbank features.
Structural alteration of pyrophyllite by dry grinding as studied by IR spectroscopy

Fine particles are obtained by grinding (wet or dry), the nature of which plays an important role in determining the physicochemical properties of the powdered material [1-3]. In particular, the effects of grinding on clay minerals have been studied mainly for kaolinite [4-6] and montmorillonite and bentonite [7, 8] in view of their importance as ceramic raw materials. Concerning pyrophyllite, A14Si8020(OH)4 , Levine and Joffe [9] described in a pioneering work some grinding experiments using this silicate. Hayashi et al. [10] studied the continued grinding of pyrophyllite and its effects on toxicity of the cell. Juh~isz [11] suggested that destruction of this silicate during mechanochemical activation (intensive dry grinding) may be accelerated by cations and adsorbed water. Other researchers, e.g. Okuda et al. [12], have studied the density of charges on the edge and basal surfaces of dryand wet-ground pyrophyllite. Industrial grinding of pyrophyllite materials has also been examined to determine the efficiency of the method [13, 14], and to separate pyrophyllite from other minerals [15]. These results are of great interest in the processing of advanced ceramics starting from pyrophyllite. In previous papers [16-19] the authors studied the effects of dry grinding on this silicate and its influence on thermal behaviour, focusing mainly on mullite formation from the activated ground material. However, the structural alteration induced on pyrophyllite by dry grinding as deduced by IR spectroscopy has not been extensively studied. The only authors to report some scarce IR spectroscopy data were Hayashi et al. [10]. Thus, the aim of the present letter is to provide more detailed structural information on pyrophyllite after grinding using IR spectroscopy. A sample of pyrophyllite from Hillsboro (North Carolina, USA) was used as starting material. Dry-grinding experiments were performed using a ball mill (Model S-l, Retsch) as described previously [17, 18]. IR absorption spectra in the region 4000-400 cm -1 were recorded on a spectrophotometer (Model 377, Perkin-Elmer) using KBr pellets. X-ray diffraction (XRD) patterns were obtained on a diffractometer (Model D-500, Siemens) using Ni-filtered CuKo~ radiation. Samples were prepared
Investigation of the Impact of Surface Properties of a Gas Electron Multiplier on its Performance

A Time Projection Chamber (TPC) is foreseen as the main tracking detector in the International Large Detector (ILD) one detector concept for the planned International Linear Collider (ILC). This TPC will use Micro Pattern Gaseous Detectors (MPGDs) for amplification, of which Gas Electron Multipliers (GEMs) are one possibility. This thesis is embedded in a series of studies on the long term high voltage stability of GEM foils and efforts to improve it. A possible candidate to avoid or lessen the negative effects of electrical discharges is the coating of the GEM copper surface with a thin layer of copper oxides. Such a coating presumably would offer a simple possibility to increase the GEM stability, since it can easily be applied by heat treating the foils in air. In this thesis, GEM foils were systematically heat treated and results are described. Firstly, the effect of different parameters as duration and temperature of the heat treatment on the oxide layer was studied. The GEMs foils were analyzed regarding their surface properties in terms of roughness, thickness, composition and resistivity. The results are described in detail and compared to the properties of untreated GEMs. Secondly, the high voltage stability and gas gain performance of untreated and heat treated GEMs are compared. As part of the high voltage stability tests the nature of shorted GEMs is investigated as well. The hope to find a set of parameters for a simple baking procedure which is able to significantly improve the GEM performance in all aspects can not be confirmed within the work presented here.
Music Synthesis based on Impression and Emotion of Input Narratives

This paper presents a technique to synthesize the music based on the impression and emotion of the input narratives. The technique prepares a dictionary which records the sensibility polarity values of arbitrary words. The technique also supposes that users listen to the sample chords and rhythms, and input the fitness values to the pre-defined impression word pairs, to learn the relations between features of chords/rhythms and these impression. After these processes, the technique interactively synthesizes the music for input narratives. It estimates the fitness values of an input narrative to the impression word pairs using the dictionary, and then selects the chord and rhythm progressions those impressions and emotions are the closest to the narrative. Finally, the technique synthesizes the output tune by combining the chord and rhythm. We suppose this technique encourages to express impression and emotion of the input narratives by generating music.
Carotenoid profile of a vegetable by-product .

In recent years, bioactive compounds such as carotenoids present in by-products from fruits and vegetables are receiving increased attention because of their potential antioxidant activity which is related to several health benefits. Also, integral exploitation was recognized as a sustainable action that reduces the disposal of waste by food industries. Peels and seeds are the major residue obtained during the processing of fruits and vegetables and for the past few decades have been considered as important sources of bioactive compounds and pigments. The aim of this study was to assess the total carotenoids content of a dry residue obtained from the manufacturing of a natural supplement by HPLC-DAD; and the concentrations of lutein, α-carotene, β-carotene, lycopene, 13-cisβ-carotene and 9-cis-β-carotene. β-carotene was predominant (1317 ± 207 μg.100g-). Lower amounts of other carotenoids were also observed indicating that this residue could be a valuable source of carotenoids.

Innovating the Food Value Chain ” Postharvest Technology and AgriFood Processing Stellenbosch , South Africa – 25-28 November , 2012 Integrated Test of An Autonomous Tomato Picking Robot

The objective of this research is to develop and test an autonomous picking robot system for greenhouse-grown tomato, which consists of four major components: the end-effector, the machine vision, the robot carrier, and the control system. The robot carrier and its platform can move horizontally and vertically, respectively on the rails automatically for positioning control, and capture and analyze images automatically, so as to identify fruit. The end-effector was designed with four fingers that have foam sponge pads inside to reduce damaging the fruit when bending and gripping. By controlling solenoid activation, the fingers are bent to reduce the opening of the tip, securing the fruit inside the end-effector. The center of the end-effector is a fruit suction device, which assists the fixation of fruit to the inside of end-effector, enhancing the holding performance. During the automated picking operation, the robot carrier first moves to the designated position. The binocular vision system then takes photographs to calculate the three-dimensional coordinates of the fruits to be picked. The robotic arm then positions the end-effector in front of the fruit, where the fruit suction device is initiated to hold the fruit in the end-effector. After the fruit is grasped securely, the endeffector twists the fruit to detach it from the peduncle before finally placing the fruit in the harvest basket, completing one picking operation. Test results showed that the successful picking rate was 73.3%. The overall success rate of the fruit suction device was 93.3%. The visual system identification success rate was 100%. Future field test should increase the feasibility of developing automatic robotic picking systems.
Withaferin A induces Nrf 2-dependent protection against liver injury : role of Keap 1-independent mechanisms

Small molecules of plant origin offer presumptively safe opportunities to prevent carcinogenesis, mutagenesis and other forms of toxicity in humans. However, the mechanisms of action of such plant-based agents remain largely unknown. In recent years the stress responsive transcription factor Nrf2 has been validated as a target for disease chemoprevention. Withania somnifera (WS) is a herb used in Ayurveda (an ancient form of medicine in South Asia). In the recent past, withanolides isolated from WS, such as Withaferin A (WA) have been demonstrated to be preventive and therapeutic against multiple diseases in experimental models. The goals of this study are to evaluate withanolides such as WA as well as Withania somnifera root extract as inducers of Nrf2 signaling, to probe the underlying signaling mechanism of WA and to determine whether prevention of acetaminophen (APAP)-induced hepatic toxicity in mice by WA occurs in an Nrf2-dependent manner. We observed that WA profoundly protects wild-type mice but not Nrf2-disrupted mice against APAP hepatotoxicity. WA is a potent inducer of Nrf2-dependent cytoprotective enzyme expression both in vivo and in vitro. Unexpectedly, WA induces Nrf2 signaling at least in part, in a Keap1-independent, Pten/Pi3k/Akt-dependent manner in comparison to prototypical Nrf2 inducers, sulforaphane and CDDO-Im. The identification of WA as an Nrf2 inducer that can signal through a non-canonical, Keap1-independent pathway provides an opportunity to evaluate the role of other regulatory partners of Nrf2 in the dietary and pharmacological induction of Nrf2-mediated cytoprotection.
Chapter 2 Use of Luciferase Chimaera to Monitor PLC z Expression in Mouse Eggs

The microinjection of cRNA encoding phospholipase C (PLC zeta) causes Ca oscillations and the activation of development in mouse eggs. The PLC protein that is expressed in eggs after injection of cRNA is effective in causing Ca oscillations at very low concentrations. In order to measure the amount and timecourse of protein expression we have tagged PLC with firefly luciferase. The expression of the luciferase protein tag in eggs is then measured by incubation in luciferin combined with luminescence imaging, or by the lysis of eggs in the presence of Mg-ATP and luciferin in a luminometer. The use of luciferase to monitor protein expression after injection of cRNA is a sensitive and effective method that efficiently allows for sets of eggs to be used for PLC quantitation, Ca imaging, and studies of embryo

EFFECT OF ULTRAVIOLET IRRADIATION ON THE OPTICAL AND STRUCTURAL CHARACTERISTICS OF IN-SITU PREPARED PVP-Ag NANOCOMPOSITES

Silver nanoparticles dispersed Polyvinylpyrrolidone (PVP) nanocomposites were prepared by in-situ chemical reduction of silver nitrate (AgNO3) from an ethanolic solution of PVP. The prepared nanocomposite films were subjected to ultraviolet (UV) irradiation at room temperature for different times. The effect of UV-irradiation has been studied through electron microscopy, optical spectroscopy and FTIR spectroscopy. The appearance of Surface Plasmon Resonance (SPR) band at ~ 420 nm in the UV-Visible absorption spectra indicates the presence of the silver nanoparticles. The optical band gap values were found to reduce from 4.90 eV in pure PVP to 4.11 eV for PVP-Ag nanocomposite prior to irradiation. This value is further reduced to 3.55 eV after UV irradiation for 180 minutes. Such a reduction in optical band gap may be linked to the increased conjugation in PVP matrix as an effect of embedding of silver nanoparticles followed by UV-irradiation, as observed through FTIR analysis.
Simple correlated wavefunctions for excitons in 0 D , quasi-1 D and quasi-2 D quantum dots

We propose correlated yet extremely simple single-parameter-dependent wave-functions with a Slater-type correlation factor, to describe excitons in 0D, quasi-1D and quasi-2D semiconductor quantum dots. We provide closed-form formulas for the wave-function normalization factor, electron/hole single-particle density and the expectation value of the kinetic energy. We additionally supply fast integration procedures for the Coulomb interaction in the presence of dielectric mismatch with the surrounding medium for nanoplatelets (quasi-2D systems), and for the bare-Coulomb integral in long nanorods (quasi-1D systems).
OF A HIGH-PERFORMANCED VIBRATOR FOR LINEAR ULTRASONIC MOTORS USING A GENETIC ALGORITHM AND A FINITE ELEMENT ANALYSIS

An optimum design method is proposed for designing the vibrator for the linear ultrasonic motors using genetic algorithms, finite element method and evaluation function based on design conditions. As a result, basic geometry of the vibrator for small-sized and high-performanced linear ultrasonic motors is generated. Dimension is within ten millimeters wide and twenty millimeters long. Obtained geometry of the vibrator satisfies all the design conditions. The obtained geometry and natural vibration modes of the vibrator are so identical that it can not be designed by the trial and error by designers.
Beliefs on Parenting and Childhood in India

In the investigation of parent-child interactions, studies on parent-child relationships, parent attitudes, discipline methods and their impact on children's development have been the primary areas of research. Developmental researchers in various cultures have over the years focused much of their attention on accounts of socialization pattems and the overt behavior of parents (what parents do) with limited attention to their thoughts as parents (what parents believe). Parental behavior has been the preferred pathway to understanding development. The formal study of parenting beliefs, ideas or cognitions is seen by some to have begun in the 1950s in research that interviewed parents to gather information about socialization practices, the home environment and parent child relationships (Rubin and Mills, 1992; Sears et al., 1957). Later this trend was reversed with objections being raised about the validity and accuracy of reports and recall made by parents, the weak correlation between beliefs and behavior and the feeling that much behavior may not have any salience for parents and hence they may not be able to comment on it. So for a long period, parental ideas were not the focus of research. The revival of interest in parental cognitions and ideas is a recent development (Kagitcibasi, 2007).

Poverty is a complex issue because it involves a variety of aspects such as the fulfillment of the right to food, health, education, employment, and so on. The Government had been many issued in the framework of poverty alleviation programs, but the implementation of such programs, especially in South Jakarta is not maximized, proven by Central Statistics Agency South Jakarta totaled 9,608 poor people poor households. This phenomenon became the background of this research. The purpose of this study is to develop a concept for reducing poverty with microcredit. Particularly poor effort in utilizing micro-credit assistance. The method used in this study is using a qualitative approach, with a knife phenomenological analysis. Phenomenology is used to gain experience of the poor as it navigates life. The results showed that the effectiveness of poverty reduction with the help of micro-credit is determined by two factors: factors driving and inhibiting factors. The driving factor is composed of market-oriented marketing management, customer orientation; especially entrepreneurial business development, creativity and honesty, perseverance and tenacity; responsibility to maintain the trust; commitments that have access to credit, strong determination; discipline that prioritizes timeliness accompanied by an increase spiritual to draw closer to God. While the inhibiting factors that emergencies caused by natural disasters, non-fulfillment of basic needs, especially the problem of consumption; low competitiveness due to the identification of products and market competition KEYWORD: Microcredit, Poverty Alleviation
Direction of Arrival Estimation for Complex Sources through ` 1 Norm Sparse Bayesian Learning

In this letter, Laplace distribution is used to model the prior for the direction of arrival (DoA) of sources. In order to incorporate the real and imaginary part of the received signal, we propose a method that pairwise estimates the hyperparameters for parts of the signal coefficients. In addition, we propose a multi-task algorithm to extend the application of our method to the situation where multiple measurements are available. Nonuniform linear arrays are used to demonstrate the validity and advantages of the proposed method including its improved efficiency and accuracy compared with state-of-art DoA estimation methods.
HYBRID NUMERICAL SIMULATION OF FLOW-INDUCED RADIATION OF AIR-DUCTING STRUCTURES LINED WITH POROUS MATERIAL

Airflow plays a vital role in a significant number of today’s appliances, e.g. in heating, ventilation, air condition (HVAC), intakes, exhausts. The expectations from their users are not restricted to proper operation but also include aspects of comfort, especially in terms of low noise emission. Air flow through structures generally generates two types of sounds: the aero-acoustic sound resulting from turbulences within the flow, and the sound radiated from the structure which undergoes excitation due to the flow. In this work, the latter case will be examined and the effectiveness of porous liners in order to reduce structural vibrations and hence sound radiation is studied. The chosen approach builds a model made up from four interacting parts: air flow, porous liner, structure and surrounding space. ANSYS CFX a commercial computational fluid dynamics (CFD) software which makes use of the Reynolds Averaged Navier-Stokes equations in a Volume-of-Fluid method is used to simulate the air flow. The liner is represented by Biot’s theory for poroelastic materials and is discretized by means of the finite element method (FEM) as continuum elements. The structural part is modeled as a shell, also using FEM. The boundary element method (BEM) is chosen to simulate radiation into the surrounding air.
