Published: October 2019

Abstract
The paper shows and investigates the technique of classifying the particle size of powder and granulated materials. The objects of the study are industrially produced mineral fertilizers. Samples with different composition (about five types of mineral fertilizers) and various degrees of particle size (less than 100 µm, less than 500 µm and granules of 2-5 mm) were examined. The samples particles have an irregular shape, close to spherical (in the case of granules) or cubic (in the case of powders). To improve the accuracy and eliminate the particle shape influence on analysis, the preliminary pressing of samples on a boric acid substrate was used. The keynote of the proposed technique is to obtain an optoelectronic image of an object with a resolution of at least 640x480 pixels (a three-dimensional matrix of pixel intensity in the Red-Green-Blue (RGB) system). Next, the area of analysis is separated from the obtained image and transformed into grayscale (a two-dimensional matrix of pixel intensities with a resolution of at least 200x200 pixels). The influence of external illumination (gradient, temperature and brightness) is eliminated by the grayscale image differentiation. The result is the “surface map” of the sample, which reflects defects in the pressed structure (patterns, which are responsible for the size of the particles). According to the found patterns, the samples are classified according to their particle size. Four classification algorithms were investigated (linear, linear with L1 and L2 regularization, and a nonlinear “random forest”). All proposed approaches are automated and implemented in the Python 3.6 programming language. There is provided the selection of the operating parameters of all the described algorithms.

Authors: Khan Fatima Najeeb , Batul Beenish , Aizaz Ahmad 
Published: October 2019

Abstract
The present study investigates the use of various wingtip devices to analyse the parameters of lift and drag for an aircraft wing. The coefficients of lift and drag are investigated in this research to optimize the wing design for enhancing the aircraft performance. A reduction in the drag produced due to wingtip vortices leads to reduced fuel consumption which contributes to the reduction in fuel emissions. The two-dimensional analysis is carried out for the selection of an apposite aerofoil by comparing the lift/drag characteristics of NACA 0012, 2415 and 23015 respectively at the velocity of 79.16 m/s at the angles of attack of 0°,4°,8°,12°,16° and 20°. The aerofoil section NACA 2415 is used to design the three-dimensional aircraft wing. For the analysis of the various wing tip devices the three-dimensional wing is incorporated with the spiroid winglet, blended winglet, wingtip fence and a mini-winglet. The CFD analysis for the wing designs is carried out for the take-off and landing phases of an aircraft’s flight because the effect of vortices is the highest during these flight phases. The angles of attack range from 0° to 20°. The CFD results reveal that for the wing designs, the plain wing produced the highest drag and the blended winglet proved to be the wingtip device with the most beneficial design. The results obtained for the 30° cant angled blended winglet and 60° cant angled wingtip fence produces additional lift when compared to the results obtained for the counterpart designs. The results obtained from the analysis are in close correlation to the established use of the wingtip devices.

Published: October 2019

AbstractA traditional scarecrow does not scare birds; subsequently, crops will be demolished by birds during the growing season. Moreover, because farms are often invaded and crops stolen during harvest, the farmer and his dogs are forced to stay and protect the crops. However, this is not efficient for a large farm. Therefore, a remote crop monitoring security system is necessary. In order to maintain sufficient electrical power used by the system, green electrical energy generated by both a solar board and a wind generator are adopted. This system placed in each section of the farm includes five ultrasonic sensors, a microcontroller, a twinkling lighting, and a speaker unit. To ensure efficiency when using the crop security system, crops in huge areas will be divided into several small zones for monitoring. Each zone will have an individual crop security system. When a sensor detects an intrusion of birds, the alarm and light will be initiated. With this, any birds or other intruders will be scared and leave the field.

Published: October 2019

Abstract
Decarburization layer depth has great influence on the quality of metal forming process. For determining the depth value, the inspector progresses the measurement by manual nearly, which is subjective and inconsistency. This paper presents a digital analysis approach for measuring the decarburization depth automatically. Meanwhile, this analysis can be carried out by a portable device. For the digital analysis approach, the morphology image process is developed by comparing the variation of gray gradient of image from edge to core region. While the histogram of grayscale gradient falling down sharply, the distance from edge to the point was defined as the ferrite decarburization depth. Meanwhile, if the histogram keeps decreasing and stopping the decrease at one point, then the distance from edge to that point was defined as the totally decarburization depth. For the portable device, the analysis software is settled on a cloud-based calculating system. The analyst can capture the metallographic image shown in the monitor by smart glasses. Then, the analysis result is shown in smart glasses directly. All analysis and calculation process are progressed on a cloud-computing system. Finally, a digital metallographic analysis approach for estimating decarburization depth of carbon steel specimen by a portable device can be carried out.

Published: October 2019

Abstract
IEEE 80211ah is a low speed and long distance communication protocol which has two modes of operation: one is that stations in RAW need to listen Beacon for data transfer, and the other is that stations in Non-TIM TWT mode need not to synchronous with AP by listening Beacon. 802.11ah with Non-TIM TWT strategy is very suitable for many IoT applications with low speed and low energy consumption. However, there is no further discussion of energy consumption for stations under Non-TIM TWT mode in 802.11ah networks. Therefore, this paper proposes an 802.11ah Non-TIM Implicit TWT simulation which is built with the 802.11 Legacy simulator added to the transmit traffic distribution, Target Wake Time mechanism and Channel Model. This simulation analysis will evaluate energy consumption performance under different IoT applications (agricultural monitoring, smart metering, and industrial automation).

Published: October 2019

Abstract
In the era of Internet of Things (IoT), the Internet has evolved from a simple Internet function of web information access to intelligent functions of identification, position, monitoring, and management of things. Devices in the IoT must transmit data between the devices and equipment connecting to cloud. As a fog computing architecture is established proximally at the local ends of the IoT, the data transmission volume and transmission delay can be effectively reduced. IoT wireless communication is one of the essential items for complete data transmission between the devices and on-line equipment. This paper proposes the low noise amplifier (LNA) design that can be applied to the RF front-end receiver of a 2.45-GHz wireless communication system for IoT applications. The LNA is required to have characteristics of low noise factor and high signal gain in order to amplify weak signals received by the antenna. In this study, the design of 2.45-GHz LNA adopts an architecture of power-constrained simultaneous noise and input matching on the basis of the 0.18-μm CMOS process technology in order to achieve simultaneous noise and input matching at low power conditions. Both the architectures of push-pull and forward substrate bias are also utilized. The LNA demonstrates the characteristics of low noise factor, high gain, and good 1-dB gain compression. The LNA shows good potential for IoT wireless communication system applications.
Design and Simulation of a Porous Rectangular Board-Foldable Trolley
Authors: Shiau Yau-Ren , Fang Jiunn , Chen Yu-Lan 
Published: October 2019

Abstract
To reduce the structural weight and volume and satisfy an optimal balance of performance constraints, a study using a porous rectangular foldable board and structurally improved trolley model was conducted, and motion simulations were performed to derive the static and transient structural properties. The simulations revealed that the fatigue lifetimes of both the main structure and the porous boards were in a high-standard-value range, whereas the transient analysis indicated that both the directional deformation and equivalent stress exhibited minimal local values. For porous boards simply supported only on two sides, the trolley had a much smaller collapsed volume than other types of trolley. The static analysis indicated that this trolley prototype had a good safety coefficient and long fatigue lifetime. The transient analysis showed that the porous area had a higher strength and bending load than the non-porous area. The overall transient response was close to that of a steady-state, showing a negligible effect on the structure.tc.
Computational and experimental study of a hydro-dynamical landslide model based on laboratory flume tests
Authors: Kanule J , Ng’etich W , Rotich S 
Published: October 2019

Abstract
Hydrological factors such as volumetric water content (VWC) and pore-water content (PWC) have been cited widely as significant factors that trigger slope failures especially shallow landslides and debris flows. Over the years, researchers have studied these processes using a range of physically-based models which in many occasions are either too complex incorporating very many parameters or fail to mimic real field conditions. The principal objective of this study was to derive and incorporate a set of physically-based equations that describe the dependence of slope failures at laboratory scale on VWC into a factor of safety expression herein referred to as the hydro-dynamical landslide model. The model was validated by a series of physical tests on soil samples in the laboratory using the Chep-flume. Results showed a close agreement between computational and experimental data, confirming the hypothesis that cohesion, internal friction angle and pore-water pressure are modulated by VWC especially for slopes with sandy-loam soils. More so, rapid change of soil water content was observed to accelerate build-up of negative pore-water pressures (PWP) which triggers slope failure. Apart from giving a simplified expression for the factor of safety, the proposed model circumvents the difficulties associated with tedious procedures employed in the measurement of cohesive stress by limiting the tests to only three sets of parameters i.e. VWC, PWP and displacement.
Aesthetics and the other
Authors: Nanay Bence 
Published: October 2019

Abstract
‘Aesthetic and the other’ looks at the interpersonal dimension of aesthetics. Aesthetics is rarely a solitary endeavour. We are social beings and there are very few aesthetic situations that are devoid of all social aspects. The discussion of the social dimension of aesthetics in the history of ‘Western’ aesthetics has been dominated by aesthetic agreements and disagreements. But the real question about aesthetic agreements and disagreements is not about who is right and who is wrong. It is about the ways in which our experiences depend on the allocation of our attention, our background beliefs and knowledge, as well as our past exposure.
Aesthetics and life
Authors: Nanay Bence 
Published: October 2019

Abstract
‘Aesthetics and life’ considers several questions to show how aesthetics and life are intertwined on all kinds of levels. Should we treat our life as a work of art? Should we become the spectators of our own life? It discusses how not to be jaded by aesthetic experiences, how expectations can influence our experiences, how some aesthetic experiences have a lot to do with seeing something afresh, and how some aesthetic experiences can have a lingering effect. It concludes that aesthetic experience does not have to be detached, it does not need to be contemplative, and it does not need to involve open-ended attention.
Willy Loman and Postwar Jewish Insecurity
Authors: Hodin Mark 
Published: October 2019

Abstract
Willy Loman’s cryptic Jewish identity, recognizable but absent, has long been considered an act of ethnic betrayal, evidence of Arthur Miller’s inauthenticity as a Jewish writer. However, as scholars recently have explored the undercurrent of anxiety running beneath the surface of postwar Jewish life, Willy’s feelings of rootlessness, and his worries over American success, seem now particularly “Jewish.” Arguing that Willy Loman represents a postwar Jewish-American identity crisis, not a suppressed Jewish essence, the article analyzes the reception of Death of a Salesman (1949) in the Jewish press, from the pulpit, and within the synagogue community. Throughout, Willy’s preoccupation with acceptance and his eventual self-destruction resonate uncomfortably with the nightmare of European catastrophe that American Jews were then processing. In this context, the article claims that Biff’s attempt to counter his father’s world of selling by laboring in Texas, an action usually interpreted through myths of the American West, may have been read by Jewish Salesman audiences through a discourse of postwar Zionism they knew well: namely, the resettlement of Holocaust refugees in the land of Israel.
Partial Activation of TrkB Receptors Corrects Interneuronal Calcium Channel Dysfunction and Reduces Epileptogenic Activity in Neocortex following Injury
Authors: Gu Feng , Parada Isabel , Yang Tao , Longo Frank M , Prince David A 
Published: October 2019

AbstractDecreased GABAergic inhibition due to dysfunction of inhibitory interneurons plays an important role in post-traumatic epileptogenesis. Reduced N-current Ca2+ channel function in GABAergic terminals contributes to interneuronal abnormalities and neural circuit hyperexcitability in the partial neocortical isolation (undercut, UC) model of post-traumatic epileptogenesis. Because brain-derived neurotrophic factor (BDNF) supports the development and maintenance of interneurons, we hypothesized that the activation of BDNF tropomyosin kinase B (TrkB) receptors by a small molecule, TrkB partial agonist, PTX BD4-3 (BD), would correct N channel abnormalities and enhance inhibitory synaptic transmission in UC cortex. Immunocytochemistry (ICC) and western blots were used to quantify N- and P/Q-type channels. We recorded evoked (e)IPSCs and responses to N and P/Q channel blockers to determine the effects of BD on channel function. Field potential recordings were used to determine the effects of BD on circuit hyperexcitability. Chronic BD treatment 1) upregulated N and P/Q channel immunoreactivity in GABAergic terminals; 2) increased the effects of N or P/Q channel blockade on evoked inhibitory postsynaptic currents (eIPSCs); 3) increased GABA release probability and the frequency of sIPSCs; and 4) reduced the incidence of epileptiform discharges in UC cortex. The results suggest that chronic TrkB activation is a promising approach for rescuing injury-induced calcium channel abnormalities in inhibitory terminals, thereby improving interneuronal function and suppressing circuit hyperexcitability.

Abstract

Background
Diagnosis of active tuberculosis (ATB) currently relies on detection of Mycobacterium tuberculosis (Mtb). Identifying patients with extrapulmonary TB (EPTB) remains challenging because microbiological confirmation is often not possible. Highly accurate blood-based tests could improve diagnosis of both EPTB and pulmonary TB (PTB) and timely initiation of anti-TB therapy.

Methods
A case-control study was performed using discriminant analyses to validate an approach using Mtb-specific CD4+T-cell activation markers in blood to discriminate PTB and EPTB from latent TB infection (LTBI) as well as EPTB from PTB in 270 Brazilian individuals. We further tested the effect of human immunodeficiency virus (HIV) coinfection on diagnostic performance. Frequencies of interferon-γ +CD4+T cells expressing CD38, HLADR, and/or Ki67 were assessed by flow cytometry.

Results
EPTB and PTB were associated with higher frequencies of CD4+T cells expressing CD38, HLADR, or Ki67 compared with LTBI (all P values &lt; .001). Moreover, frequencies of HLADR+ (P = .03) or Ki67+ (P &lt; .001) cells accurately distinguished EPTB from PTB. HIV infection did not affect the capacity of these markers to distinguish ATB from LTBI or EPTB from PTB.

Conclusions
Cell activation markers in Mtb-specific CD4+T cells distinguished ATB from LTBI and EPTB from PTB, regardless of HIV infection status. These parameters provide an attractive approach for developing blood-based diagnostic tests for both active and latent TB.
Porcelain: another window on the neoclassical visual world
Authors: Marchand Suzanne 
Published: October 2019

AbstractThis article surveys the European, and especially German, porcelain industry’s output of classicizing figurines between about 1740 and 1900 in order to comprehend what vision of the classics Europeans wished to bring into their homes. First made by Italians, classicizing figurines and cameos became a German (and English) specialty, and helped to knit together European luxury markets as well as to spread familiarity with classical iconography to northern and eastern climes. Made for aristocratic courtiers, the first pieces reflect a ‘libertine’ classicism; by about 1790, this style had largely been displaced by a more serious and exacting (but also cheaper!) ‘chaste’ classicism exemplified by Jasperware and white biscuit porcelains. After 1815, industry conditions and the disinterest of new consumers led to the freezing of classicizing porcelains in this latter, ‘chaste’ idiom. As a widely-owned household good by the mid-nineteenth century, porcelain provided an important, if narrow, form of classical education that has left its mark on the tourist industry, and on our perceptions of the classical world.
