This document summarizes research on the inward inversion of metallic shell structures with various geometric features for energy absorption applications. Experiments were conducted using an Instron testing machine to apply loads and measure force-displacement responses for aluminum shell samples with different shapes, wall thicknesses, steps, and curvatures. Finite element simulations of the inversion process matched well with experimental force-displacement graphs and stress distributions. Key findings include frusta with 6-7 degree angles absorbed the most energy, while steps and uneven curvatures reduced energy absorption and caused unstable force responses. Thicker shells and straighter top portions also improved energy absorption performance during inversion.
This document summarizes a study on optimizing the design of an electrostatic precipitator cone structure through finite element analysis. Two models (A and B) with different stiffener arrangements were analyzed under various loads. Model B with vertical stiffeners had the lowest deformation of 36.781 mm compared to Model A's minimum of 88.114 mm, though it was heavier. Increasing the stiffener size from 150x75mm to 400x100mm decreased the deformation for both models while increasing the weight. The maximum deformation region was found to be at the center of the largest surface area. Model B was determined to be safer but more costly due to higher material needs.

Probabilistic design and random optimization of hollow rectangular composite ...IAEME Publication
This document describes a probabilistic design and random optimization of a hollow rectangular composite beam structure using finite element analysis. A Monte Carlo simulation was conducted by randomly varying design parameters like beam length, ply angles, elastic modulus, and force within defined ranges. Scatter plots of maximum bending stress were obtained for different parameter combinations. Random optimization was then performed to minimize bending stress, obtaining 1000 feasible sets. The best set that reduced bending stress the most is proposed as the optimized design.

The document summarizes an experimental study on the flexural behavior of composite reinforced concrete T-beams with horizontal transverse bars as shear connectors. Three large-scale beam specimens were fabricated, loaded until failure, and their load-deflection responses were measured. Results showed that beams with horizontal bar shear connectors had substantially higher ultimate bending capacity, flexural stiffness, and integrity compared to previous studies using headed stud connectors. The use of horizontal bars as shear connectors provides improved flexural performance of composite concrete beams cast in steel channels.

Buckling behavior of straight slot tubesunder oblique loading – A comparative...IJAEMSJORNAL
Hollow tubes are the most important or crucial parts of the rapidly growing automobile and construction industry. The tube is subjected to pure buckling. In theanalysis, one end is fixed and the force is applied to theother end and by application of different angles of inclinations ranging from 0˚ to 20˚ with different thicknessof the range of 0.5 to 2.0. Linear buckling code was used forfinding the critical buckling load. This research paper is about the effects of buckling under oblique loading. It is the process in which the tube is subjected to compressive oblique loading and the tube fails by the first increase in crossectional area and then bulging on any of the sides but in the case, oblique loading in hollow tube shell bulges internally or inside the perimeter of the tube.
A study on plastic hinge formation in rc frame by nonlinear static analysiseSAT Journals
This document presents a study on plastic hinge formation in reinforced concrete (RC) frames under nonlinear static pushover analysis. A single-bay, single-story RC frame is modeled and analyzed using SAP2000 software. The order and location of plastic hinge formation is observed as the frame is subjected to incremental lateral loading. Four plastic hinges form in total. The sequence of hinge formation is found to control the deformation behavior of the frame. Understanding hinge formation and the gap between successive hinges forming provides better insight into the performance of the structure under earthquake ground motions.
Comparison of the lateral deflection at midpoint of long & short side columnIAEME Publication
This document summarizes a study that used finite element analysis to compare the lateral deflection of long and short side reinforced concrete columns subjected to blast loading. The analysis used ANSYS to model 8 columns with different transverse and longitudinal reinforcement. It found that the long side columns experienced significantly higher maximum lateral deformations than the short side columns. Ratios of short to long side column deformation ranged from 0.24 to 0.38 depending on the column. The study concluded that column length and orientation affects deformation under blast loading, with long side columns experiencing greater impacts.

Analysis of Parabolic Shell by Different Models Using Software SAP 2000ijtsrd
The shell structure consists of a thin reinforced concrete shell without the use of internal columns to create an internal opening., parabolic or spherical cross section. On the other hand, warehouses and playgrounds are conventional concrete frame structures, on the other hand, they can be difficult to design as the exact shape required for the stability of the structure depends on the material used, the dimensions of the enclosure, external or internal loads and other chamfers.. .. Thus, by changing the shell parameter, the performance of the shell will also change. The main goal of this work is to parametrically analyze different designs of cylindrical shells of different lengths in order to analyze two different lengths of taken cylindrical shells, and then change two parameters, first the radius and then the thickness, based on the radii. and the difference in thickness for the same width, length and material of the frame, we will evaluate the behavior of the frame for different models.

Seismic behavior of steel rigid frame with imperfect brace membersIAEME Publication
This document summarizes a study on the seismic behavior of steel rigid frames with imperfect brace members. A finite element model was developed using shell elements to model base columns and portions of brace members, in order to account for local buckling effects. Nine frame specimens were analyzed with I-section brace members having varying slenderness ratios. Nonlinear time history analyses were conducted under earthquake ground motions applied in both longitudinal and transverse directions. Results were compared between models using shell elements and beam elements to investigate the impact of local deformations. It was found that ignoring local deformations led beam element models to not accurately predict maximum responses, particularly for components with higher buckling susceptibility.
This document describes a study that developed a finite element model (FEM) to more accurately model transmission towers. The FEM considers factors like member continuity, asymmetric member properties, geometric and material nonlinearities, and eccentric connections. The FEM is first verified using experimental test results. Then, the FEM is used to analyze the effects of connection rigidity on transmission tower behavior. Three models are considered - fully rigid connections, in-plane pin connections, and fully pin connections. Results show connection rigidity significantly impacts ultimate load capacity, with fully rigid connections having the highest capacity. Failure occurs due to main brace bending.
Comparison of Seismic Behaviour of Multi Storey Reinforced concrete Structur...IJRAT
This document summarizes a study analyzing the seismic behavior of dual systems in a G+14 reinforced concrete building using different shear wall arrangements. Five models were analyzed: a bare frame; SMRF and shear walls at corners; SMRF and shear walls at the perimeter; flat slab and shear walls at corners; and flat slab and shear walls at the perimeter. Nonlinear static pushover analysis found that a flat slab and shear walls at corners configuration had the highest base shear and story shears. Story drift was lowest with a flat slab and shear wall combination. The bare frame model performed most poorly seismic zone V due to the lack of a lateral load resisting system. Overall, the dual systems considered provided life safety performance under seismic

Abstract The main objective of this study is to investigate the structural integrity, stability and their comparison due to the effects of longer span floor systems considering some constancy in the multi-storied commercial and residential mixed-used structures. In recent times, mixed-use developments and buildings have created an up surging demand in perspective of relatively small area of lands like Bangladesh. But, the commercial developments consisting of underground basement required maximize serviceable column free open-floor spaces for more flexibility, marketability and uninterrupted executive car parking of the end-users. Now, the column free open-plan floor spaces, usually ranges from 18~27 ft, even up to 45 ft. or more [5], offers a bulky change in span length of the slab that results the longer span structure. Again, the longer span structure is directly related with the beam length which promptly affects the thickness of the slab as well as the sizes of beams, columns and the foundations. In this study, two different span lengths of the mixed-use structural Models are considered based on the economical range [18ft-30ft] of the RC floor systems. Then, both of the structural Models are compared based on the following parameters: design aspects, reduction in the number of components, sizes & thickness, weight of steel and volume of concrete. It is found that, longer span structure keeps highest effects on the RC columns and increase in size by 104.3%. This study will also be helpful for a designer to select an appropriate size of the structural components within the economical ranges of these types of particular RC structures in future Keywords: Regular Span Structure, Longer Span Structure, Flat Plate Slab, Flat Slab, Edge Supported Slab Andmat Foundation.
Finite Element Modeling On Behaviour Of Reinforced Concrete Beam Column Joint...IJERA Editor
Recent earthquakes have demonstrated that most of the reinforced concrete structures were severely damaged during earthquakes and they need major repair works. Beam column joints, being the lateral and vertical load resisting members in reinforced concrete structures are particularly vulnerable to failures during earthquakes. The existing reinforced concrete beam column joints which are not designed as per code IS13920:1993 must be strengthened since they do not meet the ductility requirements. The Finite element method (FEM) has become a staple for predicting and simulating the physical behaviour of complex engineering systems. The commercial finite element analysis (FEA) programs have gained common acceptance among engineers in industry and researchers. The details of the finite element analysis of beam column joints retrofitted with carbon fibre reinforced polymer sheets (CFRP) carried out using the package ANSYS are presented in this paper. Three exterior reinforced concrete beam column joint specimens were modelled using ANSYS package. The first specimen is the control specimen. This had reinforcement as per code IS 456:2000. The second specimen which is also the control specimen. This had reinforcement as per code IS 13920:1993. The third specimen had reinforcement as per code IS 456:2000 and was retrofitted with carbon fibre reinforced polymer (CFRP) sheets. During the analysis both the ends of column were hinged. Static load was applied at the free end of the cantilever beam up to a controlled load. The performance of the retrofitted beam column joint was compared with the control specimens and the results are presented in this paper.

Two different schemes called “ties and longitudinal stiffeners” were proposed for improving the performance of stainless steel square thin walled tubes. An analytical study using finite element models loaded axially has been conducted. Both geometric and material nonlinearities were considered. Those models were verified against the results obtained from previous researches. The analytical study compared between unstiffened, ties stiffened and longitudinally stiffened stainless steel square thin walled tubes. The studied parameters were square thin walled tube width-to-thickness ratio (W/t) and the axial spacing of stiffening along the length. It was observed that the axial load strength can be enhanced by proposed ties stiffening schemes.

Optimum participation of beams and columns in lateral resistance of steel mom...Alexander Decker
This document discusses optimizing the participation of beams and columns in providing lateral resistance in steel moment frames. It presents research on five steel moment frames with varying numbers of stories and bays. The frames were modeled in ETABS2000 software and subjected to earthquake loads. The research aims to determine the optimum ratio of story drift to maximum allowable drift, based on the ratio of beam and column flexural stiffness. It found that increasing the flexural stiffness of columns, while keeping beam stiffness constant, reduced lateral displacement and brought story drift within allowable limits. Controlling the ratio of beam and column stiffness provides a way to optimize lateral frame resistance and displacement.
IRJET- Buckling Analysis of Corrugated Hollow Columns using Trapezoidal and S...IRJET Journal
This document presents a numerical study on the buckling behavior of corrugated hollow steel columns under axial loading using trapezoidal and sinusoidal corrugations. Finite element analysis was conducted in ANSYS to analyze rectangular hollow columns with and without ultra high strength steel tubes. Columns with trapezoidal corrugations and ultra high strength tubes exhibited the highest buckling load of 1269.04 kN, indicating greater load carrying capacity compared to other column designs. The study concluded that corrugated columns can carry double the load of conventional columns, are lighter and more efficient due to their hollow structure, and that ultra high strength tubular columns allow for even higher load capacities in a very thin cross-section.

This document summarizes a study that used finite element analysis to analyze the behavior of concrete-filled steel tube (CFST) columns connected by different methods under various loading conditions. Four square CFST columns were connected using vertical steel plates, plates with perforations, plates with lacings, and lacings with additional horizontal plates. The columns were subjected to axial, lateral, and eccentric loading. The finite element software ANSYS was used to analyze the load-deflection behavior, stress distribution, ductility, and strength of the different connection methods. The connection with lacings and horizontal plates performed best under all loading conditions based on the strength, ductility and load-deflection analyses.
Numerical Simulation of Impact of Truncated Cone Projectile On Thin Aluminum ...IJERA Editor
This document presents a numerical simulation of the impact of a truncated cone projectile on a thin aluminum plate. The simulation was performed using Abaqus explicit software. A Johnson-Cook model was used to define the material behavior of the aluminum plate. The simulation found that the ballistic limit for the 0.82mm thick aluminum plate was 24 m/s. Above this velocity, the plate was perforated by the projectile. The residual velocity of the projectile increased with higher impact velocities. Energy absorbed by the plate also increased as impact velocity rose.
Finite Element Analysis of Obround Pressure VesselsIJMER
This document summarizes a finite element analysis of obround pressure vessels conducted using ANSYS software. Circular and obround pressure vessel models were created and analyzed under internal pressure loading. For the circular vessel, hoop stress results from finite element analysis matched analytical solutions. Higher stresses and deformations were found in the obround vessel compared to the circular vessel. A parametric study examined the effect of varying the radius of the curved portion, vessel thickness, and internal pressure on hoop stresses. In all cases, stresses decreased as dimensions increased and pressure. The analysis provides valuable information on stress distributions in obround pressure vessels.
NUMERICAL INVESTIGATION ON THE PUNCHING BEHAVIOR OF RC FLAT SLABS STRENGTHENI...IAEME Publication
In this paper, the effectiveness of textile-reinforced mortar (TRM) and fiberreinforced
polymer (FRP), as a means of improving the punching behavior of
reinforced concrete flat slabs were numerically investigated. Finite element (FE)
model using ABAQUS computer program was developed to analyze eight half-scaled
slabs, in terms of load-carrying capacity, ductility, stiffness, and crack patterns. These
eight specimens were divided into two groups (G1 and G2) with four specimens for
each of them. Specimens of G1 was similar to that of G2 in all details but differ in the
eccentricity of the applied load. Specimens of G1 were tested with concentric load,
while these of G2 were tested with 150 mm eccentricity. For each group, one specimen
was built as control (unstrengthened), one was strengthened by FRP-sheet, and the
other two was strengthened by TRM-jacket with two different mesh opening (10 and
20 mm). The results obtained from FE analysis showed that the efficiency of TRM in
increasing the punching shear capacity of strengthened slabs was less than that of
FRP. In addition, the slabs strengthened by TRM showed stiffer behavior than that
strengthened by FRP, but lesser ductile. TRM effectiveness was sensitive to the mesh
size of the textile. When the mesh size decreased, stiffness was increased and ductility
was decreased.

The study collected data through questionnaires from 50 customers, 50 marketing managers, and 50 doctors in Gujarat, India. The data was analyzed to understand perceptions of DTCA's impact on clinical issues, psycho-social issues, and the doctor-patient relationship. Marketers and doctors were skeptical DTCA could improve health outcomes, while customers believed it provided treatment information. Professionals agreed DTCA could empower patients but may also cause unnecessary fear. The study provides insight into Indian stakeholders' views on introducing DTCA for prescription drugs.
The document discusses using a genetic algorithm approach to optimize process parameters in laser beam welding of Inconel. Experiments were conducted varying pulse duration, pulse frequency, welding speed, and pulse energy. Response surface methodology was used to develop mathematical models relating the weld bead geometry (penetration, width, volume) to the process parameters. The models are then used with a genetic algorithm to optimize the total bead volume while keeping the other geometry parameters within constraints, in order to produce high quality welds efficiently. In summary, the proposed methodology enables determining optimal process settings for different production needs and potentially automating the welding process.

Two different schemes called “ties and longitudinal stiffeners” were proposed for improving the performance of stainless steel square thin walled tubes. An analytical study using finite element models loaded axially has been conducted. Both geometric and material nonlinearities were considered. Those models were verified against the results obtained from previous researches. The analytical study compared between unstiffened, ties stiffened and longitudinally stiffened stainless steel square thin walled tubes. The studied parameters were square thin walled tube width-to-thickness ratio (W/t) and the axial spacing of stiffening along the length. It was observed that the axial load strength can be enhanced by proposed ties stiffening schemes.

Optimum participation of beams and columns in lateral resistance of steel mom...Alexander Decker
This document discusses optimizing the participation of beams and columns in providing lateral resistance in steel moment frames. It presents research on five steel moment frames with varying numbers of stories and bays. The frames were modeled in ETABS2000 software and subjected to earthquake loads. The research aims to determine the optimum ratio of story drift to maximum allowable drift, based on the ratio of beam and column flexural stiffness. It found that increasing the flexural stiffness of columns, while keeping beam stiffness constant, reduced lateral displacement and brought story drift within allowable limits. Controlling the ratio of beam and column stiffness provides a way to optimize lateral frame resistance and displacement.
IRJET- Buckling Analysis of Corrugated Hollow Columns using Trapezoidal and S...IRJET Journal
This document presents a numerical study on the buckling behavior of corrugated hollow steel columns under axial loading using trapezoidal and sinusoidal corrugations. Finite element analysis was conducted in ANSYS to analyze rectangular hollow columns with and without ultra high strength steel tubes. Columns with trapezoidal corrugations and ultra high strength tubes exhibited the highest buckling load of 1269.04 kN, indicating greater load carrying capacity compared to other column designs. The study concluded that corrugated columns can carry double the load of conventional columns, are lighter and more efficient due to their hollow structure, and that ultra high strength tubular columns allow for even higher load capacities in a very thin cross-section.

Numerical Simulation of Impact of Truncated Cone Projectile On Thin Aluminum ...IJERA Editor
This document presents a numerical simulation of the impact of a truncated cone projectile on a thin aluminum plate. The simulation was performed using Abaqus explicit software. A Johnson-Cook model was used to define the material behavior of the aluminum plate. The simulation found that the ballistic limit for the 0.82mm thick aluminum plate was 24 m/s. Above this velocity, the plate was perforated by the projectile. The residual velocity of the projectile increased with higher impact velocities. Energy absorbed by the plate also increased as impact velocity rose.
Finite Element Analysis of Obround Pressure VesselsIJMER
This document summarizes a finite element analysis of obround pressure vessels conducted using ANSYS software. Circular and obround pressure vessel models were created and analyzed under internal pressure loading. For the circular vessel, hoop stress results from finite element analysis matched analytical solutions. Higher stresses and deformations were found in the obround vessel compared to the circular vessel. A parametric study examined the effect of varying the radius of the curved portion, vessel thickness, and internal pressure on hoop stresses. In all cases, stresses decreased as dimensions increased and pressure. The analysis provides valuable information on stress distributions in obround pressure vessels.
NUMERICAL INVESTIGATION ON THE PUNCHING BEHAVIOR OF RC FLAT SLABS STRENGTHENI...IAEME Publication
In this paper, the effectiveness of textile-reinforced mortar (TRM) and fiberreinforced
polymer (FRP), as a means of improving the punching behavior of
reinforced concrete flat slabs were numerically investigated. Finite element (FE)
model using ABAQUS computer program was developed to analyze eight half-scaled
slabs, in terms of load-carrying capacity, ductility, stiffness, and crack patterns. These
eight specimens were divided into two groups (G1 and G2) with four specimens for
each of them. Specimens of G1 was similar to that of G2 in all details but differ in the
eccentricity of the applied load. Specimens of G1 were tested with concentric load,
while these of G2 were tested with 150 mm eccentricity. For each group, one specimen
was built as control (unstrengthened), one was strengthened by FRP-sheet, and the
other two was strengthened by TRM-jacket with two different mesh opening (10 and
20 mm). The results obtained from FE analysis showed that the efficiency of TRM in
increasing the punching shear capacity of strengthened slabs was less than that of
FRP. In addition, the slabs strengthened by TRM showed stiffer behavior than that
strengthened by FRP, but lesser ductile. TRM effectiveness was sensitive to the mesh
size of the textile. When the mesh size decreased, stiffness was increased and ductility
was decreased.

Finite element simulation and investigation of thin wall impeller casting ija...Dr.Vikas Deulgaonkar
In case of casting of thin wall impeller structure, the prediction of shrinkage defect is a difficult operation and failure of such thin wall structure is a commonly encountered problem. Such failures are due to non-uniform heat transfer rate. The uniformity of heat transfer rate may enhance by placing the runner at appropriate position and riser based on the geometrical attributes. An attempt is made for the analysis of optimization in the placement of runner and riser. The present work focuses on the simulation of aluminum thin wall pump impeller blade using commercially available software (ANSYS) and experiments for optimum placement of risers and reducing defects.
IRJET - Analysis and Model for Flexural Behaviour of Confined Rectangular...IRJET Journal
This document summarizes an analysis of the flexural behavior of confined and unconfined rectangular concrete beams. Three beam samples were tested: one with internal confinement using stirrups, one with external confinement using mesh wrapping, and one without confinement. Testing found that the externally confined beam had the highest load carrying capacity and withstood the greatest strains before failure. The internally confined beam performed better than the unconfined beam but not as well as the externally confined beam. In conclusion, external confinement was found to be the most effective at improving a beam's ductility and strength.

The nonlinear behavior of concrete in compression is simulated by an elasto-plastic work-hardening model, and in tension a suitable post-cracking model based on tension stiffening and shear retention models are employed. The steel was simulated using an elastic-full plastic model. The validity of the theoretical formulations and the program used was verified through comparison with available experimental data, and the agreement has proven to be good. A parametric study has been also carried out to investigate the influence of the slab thickness on column-slab connection response

As more and more we are entering into the modern society and culture, the more we require the services of the so called ‘Khaki Worthy’ men i.e., the police personnel. Whether we talk of Indian police or the other nation’s police, they all have the same recognition as they have in India. But as already mentioned, their services and requirements are different after the like 26th November, 2008 incidents, where they without saving their own lives has sacrificed themselves without any hitch and without caring about their respective family members and wards. In other words, they are like our heroes and mentors who can guide us from the darkness of fear, militancy, corruption and other dark sides of life and so on. Now the question arises, if Gandhi would have been alive today, what would have been his reaction/opinion to the police and its functioning? Would he have some thing different in his mind now what he had been in his mind before the partition or would he be going to start some Satyagraha in the form of some improvement in the functioning of the police administration? Really these questions or rather night mares can come to any one’s mind, when there is too much confusion is prevailing in our minds, when there is too much corruption in the society and when the polices working is also in the questioning because of one or the other case throughout the India. It is matter of great concern that we have to thing over our administration and our practical approach because the police personals are also like us, they are part and parcel of our society and among one of us, so why we all are pin pointing towards them.

ATTRITION IN THE IT INDUSTRY DURING COVID-19 PANDEMIC: LINKING EMOTIONAL INTE...IAEME Publication
Globally, Millions of dollars were spent by the organizations for employing skilled Information Technology (IT) professionals. It is costly to replace unskilled employees with IT professionals possessing technical skills and competencies that aid in interconnecting the business processes. The organization’s employment tactics were forced to alter by globalization along with technological innovations as they consistently diminish to remain lean, outsource to concentrate on core competencies along with restructuring/reallocate personnel to gather efficiency. As other jobs, organizations or professions have become reasonably more appropriate in a shifting employment landscape, the above alterations trigger both involuntary as well as voluntary turnover. The employee view on jobs is also afflicted by the COVID-19 pandemic along with the employee-driven labour market. So, having effective strategies is necessary to tackle the withdrawal rate of employees. By associating Emotional Intelligence (EI) along with Talent Management (TM) in the IT industry, the rise in attrition rate was analyzed in this study. Only 303 respondents were collected out of 350 participants to whom questionnaires were distributed. From the employees of IT organizations located in Bangalore (India), the data were congregated. A simple random sampling methodology was employed to congregate data as of the respondents. Generating the hypothesis along with testing is eventuated. The effect of EI and TM along with regression analysis between TM and EI was analyzed. The outcomes indicated that employee and Organizational Performance (OP) were elevated by effective EI along with TM.

By implementing talent management strategy, organizations would have the option to retain their skilled professionals while additionally working on their overall performance. It is the course of appropriately utilizing the ideal individuals, setting them up for future top positions, exploring and dealing with their performance, and holding them back from leaving the organization. It is employee performance that determines the success of every organization. The firm quickly obtains an upper hand over its rivals in the event that its employees having particular skills that cannot be duplicated by the competitors. Thus, firms are centred on creating successful talent management practices and processes to deal with the unique human resources. Firms are additionally endeavouring to keep their top/key staff since on the off chance that they leave; the whole store of information leaves the firm's hands. The study's objective was to determine the impact of talent management on organizational performance among the selected IT organizations in Chennai. The study recommends that talent management limitedly affects performance. On the off chance that this talent is appropriately management and implemented properly, organizations might benefit as much as possible from their maintained assets to support development and productivity, both monetarily and non-monetarily.
A STUDY OF VARIOUS TYPES OF LOANS OF SELECTED PUBLIC AND PRIVATE SECTOR BANKS...IAEME Publication
Banking regulations act of India, 1949 defines banking as “acceptance of deposits for the purpose of lending or investment from the public, repayment on demand or otherwise and withdrawable through cheques, drafts order or otherwise”, the major participants of the Indian financial system are commercial banks, the financial institution encompassing term lending institutions. Investments institutions, specialized financial institution and the state level development banks, non banking financial companies (NBFC) and other market intermediaries such has the stock brokers and money lenders are among the oldest of the certain variants of NBFC and the oldest market participants. The asset quality of banks is one of the most important indicators of their financial health. The Indian banking sector has been facing severe problems of increasing Non- Performing Assets (NPAs). The NPAs growth directly and indirectly affects the quality of assets and profitability of banks. It also shows the efficiency of banks credit risk management and the recovery effectiveness. NPA do not generate any income, whereas, the bank is required to make provisions for such as assets that why is a double edge weapon. This paper outlines the concept of quality of bank loans of different types like Housing, Agriculture and MSME loans in state Haryana of selected public and private sector banks. This study is highlighting problems associated with the role of commercial bank in financing Small and Medium Scale Enterprises (SME). The overall objective of the research was to assess the effect of the financing provisions existing for the setting up and operations of MSMEs in the country and to generate recommendations for more robust financing mechanisms for successful operation of the MSMEs, in turn understanding the impact of MSME loans on financial institutions due to NPA. There are many research conducted on the topic of Non- Performing Assets (NPA) Management, concerning particular bank, comparative study of public and private banks etc. In this paper the researcher is considering the aggregate data of selected public sector and private sector banks and attempts to compare the NPA of Housing, Agriculture and MSME loans in state Haryana of public and private sector banks. The tools used in the study are average and Anova test and variance. The findings reveal that NPA is common problem for both public and private sector banks and is associated with all types of loans either that is housing loans, agriculture loans and loans to SMES. NPAs of both public and private sector banks show the increasing trend. In 2010-11 GNPA of public and private sector were at same level it was 2% but after 2010-11 it increased in many fold and at present there is GNPA in some more than 15%. It shows the dark area of Indian banking sector.

This study provides significant contributions to ultimate strength by increasing BaSO4 content up to 16% in the composites, and sliding speed contributes 72.45% to the wear rate
ROLE OF SOCIAL ENTREPRENEURSHIP IN RURAL DEVELOPMENT OF INDIA - PROBLEMS AND ...IAEME Publication
The majority of the population in India lives in villages. The village is the back bone of the country. Village or rural industries play an important role in the national economy, particularly in the rural development. Developing the rural economy is one of the key indicators towards a country’s success. Whether it be the need to look after the welfare of the farmers or invest in rural infrastructure, Governments have to ensure that rural development isn’t compromised. The economic development of our country largely depends on the progress of rural areas and the standard of living of rural masses. Village or rural industries play an important role in the national economy, particularly in the rural development. Rural entrepreneurship is based on stimulating local entrepreneurial talent and the subsequent growth of indigenous enterprises. It recognizes opportunity in the rural areas and accelerates a unique blend of resources either inside or outside of agriculture. Rural entrepreneurship brings an economic value to the rural sector by creating new methods of production, new markets, new products and generate employment opportunities thereby ensuring continuous rural development. Social Entrepreneurship has the direct and primary objective of serving the society along with the earning profits. So, social entrepreneurship is different from the economic entrepreneurship as its basic objective is not to earn profits but for providing innovative solutions to meet the society needs which are not taken care by majority of the entrepreneurs as they are in the business for profit making as a sole objective. So, the Social Entrepreneurs have the huge growth potential particularly in the developing countries like India where we have huge societal disparities in terms of the financial positions of the population. Still 22 percent of the Indian population is below the poverty line and also there is disparity among the rural & urban population in terms of families living under BPL. 25.7 percent of the rural population & 13.7 percent of the urban population is under BPL which clearly shows the disparity of the poor people in the rural and urban areas. The need to develop social entrepreneurship in agriculture is dictated by a large number of social problems. Such problems include low living standards, unemployment, and social tension. The reasons that led to the emergence of the practice of social entrepreneurship are the above factors. The research problem lays upon disclosing the importance of role of social entrepreneurship in rural development of India. The paper the tendencies of social entrepreneurship in India, to present successful examples of such business for providing recommendations how to improve situation in rural areas in terms of social entrepreneurship development. Indian government has made some steps towards development of social enterprises, social entrepreneurship, and social in- novation, but a lot remains to be improved.
OPTIMAL RECONFIGURATION OF POWER DISTRIBUTION RADIAL NETWORK USING HYBRID MET...IAEME Publication
Distribution system is a critical link between the electric power distributor and the consumers. Most of the distribution networks commonly used by the electric utility is the radial distribution network. However in this type of network, it has technical issues such as enormous power losses which affect the quality of the supply. Nowadays, the introduction of Distributed Generation (DG) units in the system help improve and support the voltage profile of the network as well as the performance of the system components through power loss mitigation. In this study network reconfiguration was done using two meta-heuristic algorithms Particle Swarm Optimization and Gravitational Search Algorithm (PSO-GSA) to enhance power quality and voltage profile in the system when simultaneously applied with the DG units. Backward/Forward Sweep Method was used in the load flow analysis and simulated using the MATLAB program. Five cases were considered in the Reconfiguration based on the contribution of DG units. The proposed method was tested using IEEE 33 bus system. Based on the results, there was a voltage profile improvement in the system from 0.9038 p.u. to 0.9594 p.u.. The integration of DG in the network also reduced power losses from 210.98 kW to 69.3963 kW. Simulated results are drawn to show the performance of each case.
