Elastic Cross-Section Modulus Ratio of Jabon (Anthocephalus cadamba Miq.) Bolt-Laminated Timber Beams
Authors: Pranata Y A , Kristianto A , Darmawan A 
Published: February 2021

Abstract
The strength and stiffness of the beams are related to the elastic cross-section modulus of the beam, which are related to the cross-section moment of inertia. The elastic cross-section modulus of mechanically laminated (bolt-laminated) timber beams are not the same as solid timber beam for the beam with the same cross-section, this can be happened due to the inertia moment of cross-section of the bolt-laminated beam is lower than the solid beam due to slip between laminae and the elastic modulus of every lamina are varying. The aim of this research was to study the elastic cross-section modulus of mechanically laminated timber using bolts as a shear connectors. The scope of the study are the beam specimens made from Jabon timber (Anthocephalus cadamba Miq.) 60 mm x 160 mm cross-section size, three beam specimens with 1500 mm clear-span length, four lamina layers, lamination system using bolt as a shear connectors to reduce slip between laminae, flexural testing using the four-point loading test method according to the ASTM D198, the flexural behavior reviewed in this research are the flexural strength, the elastic cross-section modulus ratio, and the displacement ductility ratio. The bending strength of bolt-laminated timber beams obtained from an experimental test is 12.11 MPa (average) in the term of proportional limit load, while the bending strength of a solid timber beam is 37.96 MPa. The results showed that the elastic cross-section modulus and the flexural stress of the bolt-laminated timber beams were lower with a ratio of 0.32 than the solid timber beam, and the ductility ratio of the bolt-laminated timber beams was 1.18 so that they were categorized in the limited ductility criteria. The test results indicate that the failure of bolt-laminated Jabon timber beams are a failure of bending. The elastic modulus cross-section parameters of laminated timber beams are useful for the design of beam structure components in buildings, especially in the calculation of beam strength and beam stiffness as a serviceability requirement.

Published: February 2021

Abstract
The face or the front of the head consists of the eyes, nose and mouth. Each face has its uniqueness from the many human faces. The face is used to show happy and sad expressions and feelings. Smiling also includes self-expression from others. The analysis of facial expressions plays a key role in analyzing human emotions and behavior. Smile detection is a specialized task in facial expression analysis with a variety of potential applications such as photo selection, user experience analysis, smile payments, and patient monitoring. Conventional approaches often extract low-level face descriptors and smile detection based on strong binary classifiers. In this paper, we propose an effective Histogram of Oriented method supporting vector engines for smile detection. The experimental results show that our proposed network outperforms the current state of the method. The test results using the Histogram of Oriented Gradient and Support Vector Machine method for smile detection were 87% for a precision value of 88% and a recall value of 83% and accuracy. In the future, we want to exploit some of the latest effective designs. we will try to update our mouth model so we can support a bigger head turn and face size scale.

Abstract
Highly stable catalytically active polyvinyl alcohol supported Pd nanoparticles (Pd NPs) are synthesized and used as catalysts in reduction of 4-nitrophenol in aqueous phase by sodium borohydride as reducing agent. The as—synthesized Pd NPs are characterized with the help of UV—vis. absorption spectroscopy, X—ray diffraction (XRD), transmission electron microscopy (TEM). The TEM and high resolution TEM images reveal that the synthesized Pd NPs are mostly global shaped with mean radius of c.a. 2.1 nm. The progress of the reaction is conveniently monitored by UV—vis. spectroscopy. The rate constant of the pseudo—first—order reaction increases with temperature up to 318 K. The rate constant and the activation energy for the reduction of 4-nitrophenol by using Pd nanoparticles were found as 0.013 s−1 and 14.12 kJ mol−1 respectively at 318 K. The as-prepared Pd NPs are stable, easy to prepare, cost effective and have significant efficiency for reduction of 4—nitrophenol in green protocol.

Authors: Mishra Suraj Kumar , Kumar C S 
Published: February 2021

Abstract
This paper proposes a novel 3-degrees of freedom (DOF) compliant parallel micromanipulator. The design of the mechanism is based on triglide parallel manipulator. The compliant version of the triglide is prepared by making use of flexure joints. Displacement amplifiers are incorporated in the design to increase range of motions. The pseudo-rigid-body modeling technique is then used to formulate and solve the inverse kinematic problem for the design. To check the correctness and accuracy of the analytical kinematic model FEA simulations are performed in Abaqus-6.14 environment. Simulation results reveal that the proposed micromanipulator can perform different motions very effectively. Additionally, it is found that results predicted by the analytical model conform very closely to the simulation outcomes. The errors are very low, and the motions involve negligible parasitic motions.

Authors: Qamareen Arees , Alam Shahood S , Ansari Mubashshir A 
Published: February 2021

Abstract
Combustion system design is a complex mechanism involving several physical mechanisms such as chemical reactions, fluid dynamics and heat transfer. At micro scale, short flow residence time adds further to the complexity. Enhancement of heat transfer to the outer surface of the combustor is desirable in several power generating systems. The present work focuses on this aspect by geometrical modification in the form of wall fin and observing the change in outer wall temperature level along with heat transfer rate for various wall surface emissivities and blockage ratio (BR) of wall fin. Lower surface emissivity and higher fin blockage ratio was found to give better combustor performance in terms of outer surface temperature.

Abstract
This work is focused on the implication of a partial magnetic field on a square cavity heated isothermally at the bottom wall and cooled at the sidewalls. The top wall is insulated. The enclosure is filled with electrically conducting fluid. The coupled transport equations are solved numerically using a written computing code adopting FVM and SIMPLE algorithm applying specific boundary conditions. The analysis is carried out for different involved parameters like Rayleigh number (Ra), Hartmann number (Ha), and angle of inclination (γ). The results are illustrated using contours of streamline, isotherms, and heat transfer characteristics. It is found that the flow structure, the temperature distribution is severely affected by the above-mentioned parameters. The rate of heat transfer is significantly reduced with the increasing Ha.
DEVELOPMENT OF A THERMAL MODEL OF A SOLAR POWERED VAPOUR ABSORPTION REFRIGERATION SUPPORTED GREENHOUSE FOR STRAWBERRY CULTIVATION
Authors: Ghosh Subhadeep , Ganguly A. 
Published: February 2021

Abstract
In this paper, a novel scheme of a solar powered vapour absorption refrigeration supported greenhouse with indirect evaporative cooler has been proposed. The main objective of this work is to create a favorable microclimatic condition for strawberry cultivation inside the greenhouse for a country with sub-tropical climatic conditions like India when the ambient temperature and humidity are high. The maximum yield of strawberry is achieved for a temperature ranging between 15-25 °C with a relative humidity varying from 55 to 65%. It is quite impossible to achieve a favorable temperature range for strawberry cultivation in the greenhouse under such condition by using the existing greenhouse cooling techniques. A double effect parallel flow LiBr-H2O absorption cooling system along with an IDEC powered through solar energy has been used. A thermal model for the greenhouse has been developed and analyzed for the climatic condition of Kolkata, India. The study reveals that the proposed system can very well maintain a conducive climate for the growth of target plantation for the given location.

Abstract
Many researchers are working in the field of pneumatic slurry transportation, where the rheological parameters involved in the flow. In the present work is a numerical simulation for the study of pressure drop of 30µm particle size of fly ash air mixture flow through a circular pipe was investigated through ANSYS Fluent. The present paper introduces a simplified 3-D Eulerian model along with RNG k-ε turbulent model. It was observed that the pressure drop was maximum for minimum mass flow rate of air and as the mass flow rate increases the pressure drop decreases and it becomes constant at a threshold mass flow rate for this particle size, which qualitatively matches with the experimental results observed by Bansal et al. (2013).

Proposals on calculating the differential properties of concrete
Authors: Mailyan L R , Stel‘makh S A , Shcherban‘ E M , Korobkin A P , Efimenko E A 
Published: February 2021

Abstract
Background: The paper dwells upon calculating the differential structural properties of centrifugated and vibration-centrifugated concrete as a function of the manufacturing parameters. Methods: One finding is that different layers of centrifugated and vibration-centrifugated concrete are exposed to forces of varying magnitude, resulting in these layers differing significantly in density, strength, strain, and elastic modulus. Another finding is that it is the centrifugal and centripetal forces that are key factors to be applied as arguments in calculational dependencies. Thus, the versatile calculational dependencies that make adjustments for changes in the structural properties of concrete should use these properties or their increments as functions, and the rotation inertia forces as arguments, which are in turn a function of distance from the center of rotation and the angular rotation speed. Results: This research has thus produced calculational dependencies for differential adjustment for change in all the concrete properties that have to be invoked in calculation. Conclusions: Strength- and strain-related properties of concrete that vary depthwise (i.e. across the section) are applied in the calculation procedures for more accurate and complete utilization of the available load-carrying capacity of concrete elements.

Published: February 2021

Abstract
This article examines the cultural landscape as a prerequisite for the socio-spatial strategy formation for the development of a small town in Bashkortostan. The authors of the article analyze the social, cultural contexts of small towns in the republic as the aspects of the city cultural landscape formation. Revealing the continuity of cultural, national and regional patterns of land use and management among the small towns’ residents, the authors of the article propose to consider the cultural landscape as an identity element of a small town. The article draws the conclusions about the need to use the patterns of the cultural landscape of a small town as the fundamental design frameworks for the new city spaces’ development. Following the general algorithms of urban strategizing, namely the identification of the city’s self-identity, the article proposes to use the characteristics of the cultural landscape as a semantic “core” of the small towns’ self-identification in Bashkortostan.
