Authors: Chauhan Harsh Raj , Panwar Harsh , Rastogi Vikas
Published: February 2023

Aircraft design is a multi-disciplinary iterative design process which follows a Systems Engineering approach and Unmanned Aerial Vehicle design follows one such design methodology. This paper is an attempt to formulate the structural design process for a UAVwing and subsequent optimizationfor SAE India Aero Design Challenge 2017.The design starts with the identification of structural design parameters and challenge requirements in the Pre-design/Conceptual Design phase. Based on the engineering values, a mathematical interface is coded in MATLAB to calculate the mechanical equivalents for the wing at individual sections and to prepare an internal structural layout adhering to the selected material properties. The structural design of the wing is then modelled in Solidworks and final mass is calculated in the Preliminary Design phase. For initial estimates, the static structural analysis of the layout is performed theoretically.The final design of the wing is then fed in ANSYS Finite Element Solver for Static Structural analysis. Now, successive iterations are performed for the optimization of a critical structural parameter with bound constraints directly affecting the mass of the structure using MATLAB in the Detailed Design phase. The optimized version is then finally validated.

Language Testing for Im(migration): In(validity) and Ir(relevance)
Authors: Shokeen Bharti
Published: February 2023

Linguistic proficiency has emerged as one of the key conditions for the granting of permission to stay and for naturalization in an increasing number of European as well as non- European countries. A survey in 2002 showed that 4 out of 14 countries (29%) had language conditions for citizenship; the 2007 follow-up survey revealed that five years later this number had grown to 11 out of 18 countries (61%). These tests are often used for a variety of undeclared and covert purposes, other than just 'measuring knowledge'. These 'Language tests' enable governments to use them in the context of immigration, and for the purpose of gate-keeping to regulate and restrict the entry of immigrants. (Spotti and Van Avermaet 2009:14).This article offers a vide range of possible answers, their in(validity) and ir(relevance), social desirability and level of detail required.
Software Professionals use Object Oriented data modeling instead of traditional relational data modeling
Authors: Singh Vijay
Published: February 2023

The purpose of this paper is to explain why object oriented data modeling is more popular than relational data modeling. A data model is a logic organization of the real world objects (entities), constraints on them, and the relationships among objects. Relational model is very simple since data in represented in the form of relations that are depicted by use of two-dimensional tables. Rows in the table represent records and Columns represent attributes of the entity. The basic concept in the relational model is that of a relation. In object-oriented model main construct is an object. As in relational model, there are relations similarly we have objects in OO data modeling. So first thing in OO model is to identify the objects for the systems. Examining the problem statement can do it. Other important task is to identify the various operations for these objects. It is easy to relate the objects to the real world entity. The object-oriented approach has proved to be especially fruitful in application areas, such as the design of geographical information systems which have a richly structured knowledge domain and are associated with multimedia databases. Relational data modeling is different from Object Oriented data modeling because it focuses solely on data while object oriented data models focuses on both the behavior and data aspects of your domain. OODBMS are faster than relational DBMS because data isn’t stored in relational rows and columns but as objects. Objects have a many to many relationship and are accessed by the use of pointers.

Published: February 2023

Pollution dispersion mechanism in an urban street canyon has been studied using numerical simulations. Street canyon of aspect ratio “one” with perpendicular wind flow direction and pollutant line source has been modelled using ANSYS FLUENT 16.2 software code. RNG, k-ε turbulence model and species transport model were applied in this numerical study. Pollutant mass fractions at various locations of street canyon have been studied and discussed. The numerical results show significant variations of pollutant due to existence of unsteady vortex in street canyon. Pollutant concentrations were observed higher on leeward side compared to windward side. Slow mixing rate of pollutant with fresh air leads to higher pollutant accumulation in street canyon. It has been observed that pollutant concentrations were higher at pedestrian level and decreased along the height of the street canyon.

Published: February 2023

This paper gives a brief study of the components, operating modes, merits and demerits of a four-wheel drive system over two-wheel drive system, and a case study of Mahindra Scorpio S11 is done for tractive effort by 4WD and 2WD (front wheel drive). The results for Mahindra Scorpio S11 showed that the tractive effort by 4WD system increases as the gear ratio decreases, i.e., highest for reverse gear (14362.96 Nm) with gear ratio 3.28:1, 1st gear (13000.00 Nm) with gear ratio 2.97:1, 2nd gear (9066.67 Nm) with gear ratio 2.07:1 whereas lowest for 6th gear (2451.85 Nm) with gear ratio 0.56:1. Similar results for tractive efforts by 2WD (front wheel drive) system can be depicted, i.e., highest tractive effort for reverse gear (7674.07 Nm), 1st gear (6940.74 Nm), 2nd gear (4837.04 Nm) whereas lowest for 6th gear (1311.11 Nm). As observed, the tractive effort by a 4WD system is comparatively higher than a 2WD (front wheel drive) vehicle. Thus, this results into reduced wheel slippage tendency, better climbing capability in hilly areas and better driving control over the vehicle on the low frictional surfaces such as wet/snowy surfaces. Whereas additional components in 4-wheel drive system adds on weight; increases cost, maintenance, repair, noise and vibrations; and makes the construction comparatively more complex.

Published: February 2023

Microbial xylanases have attracted a great deal of attention, due to their biotechnological potential in various industrial processes. In this study, the isolation, screening and optimization of xlanase-producing fungi from rhizosphere soil of cassava tuber under submerged fermentation were carried out. Altogether, eight fungal strains were isolated from the rhizosphere soil of cassava. All the fungal isolates were screened positive for xylanase activity on mineral salt medium supplemented with araboxylan as sole carbon source. The process parameters were optimized using one factor at a time technique. The identities of the isolates authenticated as Debaryomyces nepalensis and Penicillium polonicum by molecular techniques were regarded as good xylanase producers and they were selected for optimization studies. In order to maximize enzyme synthesis from fungi, the effect of nutritional and environmental conditions on xylanase production was investigated. The optimal incubation periods for maximal xylanase production by Penicillium polonicum and Debaryomyces nepalensis were 120 and 144 hours respectively while the optimal pH and temperature for xylanase production were 5.0 and 50oC respectively by Penicillium polonicum and Debaryomyces nepalensis. The best carbon sources for xylanase production from both fungi were found to be xylan. As a result of this, both fungal species have significant potential as sources of xylanases for industrial and biotechnological applications.
Sacred Space - Healing Islands of Urban Conglomeration
Authors: Garg Abhinav , Kesarwani Chandrakala , Gupta Tanya
Published: February 2023

India and its architecture has always been guided and shaped by its culture and traditions. Spaces reflect the traditions through the user and their activities. The word ‘Sacred’ has been linked in tremendously strong manner with widening its horizons from traditions to modernity. Sacred Groves as a concept is an ancient way to protect, preserve and value the mythology to give a sustainable future. People have strong attachments to sacred trees, gathering in their shade, socializing and developing economic spaces under them. Sacred is linked to any one single entity or one category of architecture. Sacred space is a healing sphere that is pure, holy and safe. The sacred space allows us to enter our quiet inner world, where healing takes place. Sacred space has shaped and provided deep meaning to cities and urban communities. Due to tremendous growth in urban cities, culture, traditions and values of city gets diverse. Sacred space could even be an area where a person often finds peace and the religion in work. The daily routine and regime become a part of worship. Across the culture and throughout time, people have designated sacred trees and groves as special places to meditate. Sacredness is conveyed through location, symbolism, and through the social process of creating such sites e.g. - Vrindavan, Nathdwara. Sensitivity to issues for Architecture and Urban Planners require more research and education to understand and evolve. This could be layered with social, cultural, common linkages to add more meaning and depth. The sacred can be personal, valuable in the perception of an individual or a group following tradition. The sacred space needs to achieve harmony in the multiplicity of voices found in the public. As policy makers and decision makers increasingly think of parks as green infrastructure, we much appreciate that these spaces have layered social and historic meanings.
The Transfer of What? Electronic Conveyancing and the Destabilisation of Property
Authors: Keenan Sarah
Published: February 2023

In jurisdictions around the world, the previously paper-based practice of conveyancing is being digitised. The move to ‘e-conveyancing’ has attracted little critical attention and tends to be regarded as a mere change of form rather than substance. In this article, I examine Australia’s move to national, platform-based electronic conveyancing, focusing on legal and practical changes made in the state of New South Wales to facilitate that move, asking how changes in the legal form of property affect its substance. Using legal analysis and engaging with a range of interdisciplinary literature on materiality, I argue that these digitising reforms involve a new structure of governance for the transfer of property in land, which in turn has negative implications for the relevance of subject-owns-object theories of property and the status of the proprietor. Although the diminution of proprietor status is presently occurring in ways that bolster the power of corporate finance, the shift away from older modes of landownership nonetheless presents a moment of potential disruption to the political regimes they help uphold, and an opportunity to reimagine what property is and could be.

En la vibración del acontecimiento: temporalidad eventual y activismo político
Authors: Cañedo Rodríguez Montserrat , Allen-Perkins Diego
Published: February 2023

Los acontecimientos atraviesan las biografías activistas y resignifican las memorias de la movilización social. Sin embargo, a pesar de su relevancia en los discursos de los movimientos sociales, el estudio de los acontecimientos suele abordarse desde planteamientos abstractos que impiden apreciar la complejidad y la efervescencia de las prácticas ligadas a ellos. Este artículo explora la fecundidad analítica del concepto de «acontecimiento» en distintas dimensiones de la praxis del activismo político. Nuestro objetivo es mostrar cómo el acontecimiento puede ser entendido como una unidad de significado y acción característica de las formas contemporáneas del hacer y el ser activista. El artículo se sustenta en las etnografías desarrolladas por los autores en diversos núcleos de activismo político y artístico de Madrid y Extremadura (España) a lo largo de los últimos 20 años. Los resultados muestran que el acontecimiento es un elemento de mediación esencial en las formas de participación que proveen la infraestructura del ser activista y legitiman su reconocimiento. Asimismo, cómo el acontecimiento delimita temporalidades que contribuyen a formar subjetividades que son ellas mismas eventuales. Por último, señalamos algunas paradojas de la participación y la representación políticas derivadas de una concepción de la «voluntad popular» típicamente presentista, esto es, entendida como enunciación en el aquí y ahora del acontecimiento.

Published: February 2023

By autonomous personal guarantee we will understand that contract by which one or more persons (autonomous personal guarantees) oblige themselves to another person (the creditor of the secured claim) to satisfy, at his request, the claim or claims submitted. This definition results from the provisions of art. 1628, para. 3, C. civ: "Autonomous personal guarantee is considered the obligation of the guarantor assumed for the benefit of a creditor, for the purpose of guarantee, in which it is expressly provided or from which it unequivocally follows that it does not depend on the obligation that another person owes the creditor". It follows from the definition that a third person can assume the obligation towards the creditor to guarantee the satisfaction of the creditor's claims contracted by him from the moment of concluding the autonomous guarantee contract. If in the case of suretyship, the guarantor undertakes to guarantee an obligation or obligations of the debtor, or in the case of the comfort letter, the obligation that he will determine the execution of the debtor's obligation, in the case of the autonomous personal guarantee, the guarantor assumes the obligation to satisfy a determined claim of the creditor or to satisfy all the creditor's claims arising during the entire period of validity of the guarantee contract. The personal guarantee can be particular or general.
