A Study of the Contact Interface for Compressor Blisks with Ring Dampers Using Nonlinear Modal Analysis
Authors: Sun Yekai , Yuan Jie , Denimal Enora , Salles Loïc 
Published: May 2021

Abstract
The integrally bladed disks, also known as blisks, have been widely used in industrial turbomachinery because of their benefits in aerodynamic performance and mass reduction. Friction damping is considered as the major damping sources in turbomachinery. However, in blisks, the friction damping is negligible due to the lack of the contact interfaces. The friction ring dampers are one of the emerging external damping sources for blisks. In this paper, a full-scale blisk with a friction ring damper is studied, where a 3D contact element is used to compute the contact frictions. The blisk and ring damper is investigated using their damped nonlinear normal modes. The modal damping can be directly calculated and used to quantify the friction damping generated by the ring damper. The contact behaviour within the contact interface is further analysed. The nodes with initial gap show less damping ability. The separations within the contact interface are expected to be avoided to achieve a better damping performance.

Authors: Gupta Mayank , Kulkarni N.H. 
Published: May 2021

Abstract
Ordinary Portland cement (OPC) production is boosting global warming very speedily. Therefore, geopolymer concrete is receiving huge attention as an alternative to traditional concrete because it develops without the use of OPC. Majority of the previous publications suggest that high-temperature curing required to gain higher mechanical strength and better durability properties, which is not feasible for cast-in-situ work. This obstacle has been overcome by adding calcium oxide and reducing silicon dioxide in the geopolymer. In addition, geopolymers also confront many other problems such as cost of construction, efflorescence and utilization of harmful chemical etc. that can’t be easily overcome. This literature makes an effort to identify some hurdles with the geopolymer composite in the Indian scenario. It concludes geopolymer composites will take some more time to completely replace conventional composites and requires some more improvement.

Published: May 2021

Abstract
Aluminium matrix composites (AMCs) have evolved itself in recent times as a source material for automotive applications, spacecraft applications, electronics applications and sports accessories applications. The reason for these numerous applications is their alterable mechanical properties such as good strength-weight ratio, better stiffness, excellent resistance to wear, precise co-efficient of thermal expansion, improved resistance to fatigue, and better immutability at elevated temperature conditions. All these properties are fully dependent on processing/manufacturing methods and their processing conditions. In comparison to other composite development techniques, Stir casting is an adequate method as well as it is greatly acceptable in industries. Such wide acceptability of stir casting process is by the virtue of its adaptability, cost benefits and its superiority for mass production. Therefore, this review paper compiles the details of AMC and their manufacturing methods. Among various manufacturing methods, stir casting method is described in details along with its various parameters, such as size of impeller, impeller blade angle, and position of impeller Stirring speed and stirring time for the homogeneous distribution of reinforcing material. It is still a tough task for AMCs production firms and researchers to investigate the effects of stirring process variables on the particle distribution and also adequate selection of these variables. This review encloses the study of rigorous and specific attempts made so far to investigate the consequences of stirring variables in stir casting method. Additionally for AMCs production firms and researchers, Optimized levels of stirring variables are proposed for obtaining better mechanical characteristics.

Published: May 2021

Abstract
Greater specific heat capacity of certain materials makes them a good heat storage material. Photovoltaic panels are unable to convert all the irradiation into electrical energy. Only a small fraction gets converted into electrical energy rest gets converted into heat which increases the operating temperature of cell. Higher operating temperature deteriorates the efficiency of cell. In this paper, we used results of several cooling techniques (Phase Change Material cooling, Thermoelectric cooling, Nanotube cooling etc.) to investigate their effect on operating temperature. The objective of the paper is to evaluate the varying parameters of the panel after cooling and to suggest which cooling technique offers better efficiency and panel temperature is being optimized for three different ambient conditions. The study concludes that water spraying from both front and rear side of panel results in highest variation of temperature and leads to higher efficiency of panel.

Published: May 2021

Abstract
In the photovoltaic (PV) research community, the dramatic improvement in the power conversion efficiency of organic-inorganic metal halide perovskite-based devices has made them very appealing. The serious challenge, though, has to do with durability under different circumstances and difficulties with toxicity. In recent years, a significant number of papers have been published in PSCs based on these issues through the use of different electron transport materials(ETMs), hole transport materials (HTMs), and Perovskite materials. The hole transport material is responsible for a significant part of the expense of the components of a Perovskite solar cell (PSC), as the most effective systems so far have costly HTMs, such as spiro-OMeTAD and poly(triaryl amine). The inverted PSCs (p-i-n) give a wide variety of alternate HTLs, as the HTL is deposited underneath the perovskite layer. Any material with moderate hole mobility is, therefore, a possible substitute for replacing the expensive HTMs that have been used so far. In this review manuscript, we have compiled the various Cu-based materials added as HTMs in planar inverted p-i-n) structure. This manuscript appears to focus on the role and classification of various copper-based materials used as a hole transport layer affecting long-term stability, improving solar cell parameters, and thus improving overall device performance. Furthermore, a description of the overall device structure, preparation methods, and the effect of the thickness of the HTM layers on the overall solar cell parameters of the perovskite devices is also presented. We hope that this analysis will explicitly and extensively demonstrate their significance and strengths in the concerned domain by introducing and exploring the developments of Cu-based materials as HTMs in planar PSCs and provide inspiration for their further development.

Authors: Shekhar Shashi 
Published: May 2021

Abstract
The Neural based artificial intelligence system is made linguistically intelligent through simulation model to identify pun material expressions from code mixed text. The text available on social media consist contents which are written in mixed script format and from these content puns word identification is a challenging task in this scenario. The retrieval of pun and its corresponding equivocation terms is very hard to retrieve from the transliterated text. The pun retrieval and its equivocation representation are widely used to present the opinions over the network applications. The work described in the paper gives the comparative view of different neural network and its corresponding learning and simulation techniques applied in the area of transliteration. The rule framed approach is presented which accepts the roman form text as input and as per the defined rules the system is developed to give the equivocation words available in the sentence. The evaluation measures used here to validate the hypothesis is based on statistical measures along with HLSTM learning model. Further the result is validated using the voting technique that can choose appropriate equivocation label which are not identifies by the learning model. The use of voting technique here is to provide an extra edge when the proposed approaches suggest incorrect tag against the pun word. The voting approach enhances the overall result accuracy with high precision value.
