Schiff’s base Fufural Phenylhydrazone as a Potential Corrosion Inhibitor for Mild Steel in Hydrochloric Acid Solution
Get PDFHeterocyclic Schiff base furfural phenylhydrazone [FPH] was prepared and formulated as a corrosion inhibitor for mild steel in 2M hydrochloric acid solution. Mass change measurement and electrochemical methods adapted to study the effectiveness of the FPH during the corrosion process. FPH inhibitor protected 94.53 % corrosion of mild steel at optimum inhibitor strength of 0.0007 M at 303 ±1 K. Route of corrosion protection was interpreted through adsorption of FPH molecules on specimen surfaces in acid solution. Nature of the adsorption was established via Langmuir adsorption isotherm. Stability of the inhibitor was investigated with higher temperatures. Tafel polarization curves revealed, FPH molecules exhibit mixed nature of inhibitor. SEM and AFM images suggested that corroded specimen surface was severely affected in free acid comparatively in presence of FPH inhibitor. FT-IR analysis proved that, chemical interaction takes place between specimen surface atoms with FPH molecules and established chemical bond between them
A Proposed Security System Using Object Proposals via Superpixel Segmentation
Get PDFA simple security system is presented in this paper, which can be implemented through multiple surveillance cameras, to detect trespasses and breaches of security in a wide range of real-world applications, especially on properties without fencing. The main distinguishable factor contained in the paper is the developed proposed algorithm, which largely deals with grouping objects based on superpixel properties and subsequently proposing objects in a given image. Some of the basic concepts explored include superpixel segmentation (with the help of the concept of SEEDS- Superpixel Extraction using Energy Driven Sampling) and a logical grouping of superpixels proposed to be in the same object
Inequality Adjusted Per Capita Income of Indian States in 2004-05 and 2011-12
Get PDFAs a measure of social well-being, per capita real income has a serious limitation as it reflects only the average level of income in the society disregarding whether the total income is distributed with high or low inequality among the members of the society. To address this limitation, present paper has made an attempt to calculate an inequality adjusted per capita income in India, which may be a better reflector of general wellbeing in the society. The basic methodology for calculating the inequality adjusted per capita income has been developed in line with the UNDP’s inequality adjusted human development index. The household income data of India Human Development Survey-I and II enable us to compute the inequality in per capita income in the different states of India for the two years of 2004-05 and 2011-12. For the present exercise, the inequality in per capita incomes has been captured by calculating Atkinson’s measures of inequality of the observed disparities in per capita income in the states. The purpose of the exercise is to see whether ranking of states change dramatically from their ranking by per capita income after the states are penalized because of inequality in their distributions of income. The exercise does not indicate any systematic relation between per capita income and inequality in the states of India. But the fact that some states have been able to achieve high per capita income levels while reducing their inequality implies that it is not necessary to sacrifice equity for higher growth. With adoption of naturally distributing growth patterns, it is possible to achieve higher growth with reduced inequalities
Informality in Manufacturing Sector in India
Get PDFIn many developing countries including India, a significant proportion of workers are in the informal sector which includes manufacturing, trade, construction, etc. The informal manufacturing sector has been playing an important role in employment generation despite several issues. This study aims to determine the size and sectoral (rural/urban) distribution of the informal manufacturing sector in India and the North Eastern States (NES) in recent years. The study has used secondary data from the 67th and 73rd National Sample Survey Office (NSSO) rounds and descriptive statistics like percentage and average. The percentage share of informal manufacturing enterprises has been found more in the rural than the urban areas in both rounds. During the period of study, the percentage increase in total number of informal manufacturing enterprises lies in between 13%-17% at all India level. The size of the informal manufacturing sector in the North Eastern States is seen to have declined both in absolute as well as percentage terms. This has been due to the fall in the number of units in the rural sector even though the decline has largely been offsetted by an increase in the urban sector.
ANALYSIS AND RETROFITTING OF BUILDING STRUCTURES FOR POUNDING FORCES
Get PDFLearned from recent and past Earthquake, post earthquake damages sustain structural and non-structural damage in the building even collapse of structures. This may cause the building non-functional after the earthquake, which may be problematic in some structures, like hospitals, which need to remain functional even after the earthquake. Among the all possible damages pounding is commonly observed in several earthquakes. A parametric study carried by taking two adjacent buildings G+13(45.1m) and G+8 (24.1m) for pounding forces. Two different ground motion data for input Chamoli, Elcentro Considered. The effect of pounding force is studied using nonlinear time histories in ETABS Software. Gap element is connected to calculate the pounding force between buildings. Pounding Force can be reduced effectively when separation gap provided is sufficient but Due to high land cost in dense populated areas these structures are constructed very close to each other. When two buildings are too close to each other they may Collides, which leads to pounding during strong ground motion .so it’s required to protect buildings by using special tools. For that small building is considered stiff and taller building retrofitted with fluid viscous damper to reduced pounding forces significantly. This paper deals with the analysis of pounding behavior of adjacent buildings retrofitted with fluid viscous damper. Comparative Study for different model is carried out in terms of Pounding force (impact force), displacement, number of impact, Effect fluid viscous damper to reduce global damping with or without retrofitting.Keywords: seismic pounding, Retrofitting, Nonlinear time History, Seismic analysis
Drones as a Technology-Based Key Aid for the Development of Rural India
Get PDFIn rural development, the sole objective is to create a quality of life. In India, the majority of the population resides in rural areas. Several resource-limited countries suffered from underdeveloped infrastructures that prevented equal access to various development opportunities. Initially perceived as a toy, the drone has become one of the most essential, leading-edge, and radical inventions of the modern era. The paper reveals the necessity for drone use in the country's rural areas and presents a methodical approach to adopting drones. In addition, we discuss the newly developed uses for drones in rural areas, including their specific characteristics. This report summarises all of the essential elements of drone technology to provide a framework for utilising this technology for the development of rural areas in India
MAPPING OF SITTAMPUNDI ANORTHOSITE COMPLEX (SAC) IN SOUTHERN GRANULITE TERRAIN (SGT), INDIA WITH ASTER AND SENTINEL-2A DATA
Get PDFThe Sittampundi Anorthosite Complex (SAC) is a well-exposed Archean layered anorthosite-gabbro- ultramafic rock complex in southern India. SAC well preserved white- and dark-anorthosite,gabbros, and ultramafic rocks. This study aims to discriminate, characterize, and separate from adjacent and surrounding rocks the anorthosite complex in sitampundi using Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) and Sentinel-2A data. Methods such as band color composites (True color composite, False color composite and Pseudo color composite), Principal Component Analysis (PCA), Minimum Noise Fraction (MNF) and Spectral Angle Mapper (SAM), are applied to discriminate the anorthosite complex in SGT (Southern Granulite Terrain). Band composites enhance the litho units using visible and shortwave infrared bands and thus, assisted in mapping for the anorthosite complex. PCA and MNF have been applied to the ASTER and Sentinel- 2A bands in order to decrease the redundant information in highly correlated bands. PCA and MNF driven band combinations facilitate the validation and help in discriminating the various lithological units exposed in the study area. SAM classifier classification technique was utilized to characterize the selected surface mineral assemblages from Sitampundi Anorthosite Complex using spectral signatures. The above- mentioned digital image processing techniques have been proven resourceful in discrimination of anorthosite complex and associated rocks. The results obtained from ASTER and Sentinel-2A data processing were validated in field, followed by accuracy assessment

The elephant corridors should be protected legally and there should be less interference of people in those areas
GNL: GeoFencing Based Smart Outdoor Navigation and Localization
Get PDFNavigation is a technique used by humans to construct a plan to help them travel within a place using instruments or maps. Navigation in the modern age is done using various electronic systems which provide a real-time map of the place and the step-by-step directions to the desired destination. The technology widely used today is GPS i.e. Global Positioning System. Outdoor navigation using Google maps, here maps or safari is a common go-to for the users but the problem is the map provided by these companies just has an overview of the place and not the detailed information. The GNL approach which authors have used in this paper focuses on the navigation and localization of the gated environment so that the person living and visiting the area will get familiar with the area and understand the area very well. The web app that authors have designed can be used for the College Campus, Fairs, open museums, etc. Comparative analysis of the web app-based approach is done with an existing one. The Presented approach will not only help you in navigation but also provide you with information about the POI (Point of Interests) of those visiting places. The Geofence mechanism will help users to navigate and get information about the area. The aim is to give the user the maximum information about the place with secured transfer of information and better localization. The authors have tested the approach on the real testbed in the gated society and it provides good results for what it promises
