This document summarizes a research study that used Gene Expression Programming (GEP) to develop a model for predicting scour depth at bridge abutments in cohesive soil. The study used laboratory data from previous research to develop and compare nonlinear regression and GEP models. The GEP model was found to perform better than the nonlinear regression model at predicting scour depth. GEP is an artificial intelligence technique that can model complex phenomena through simplified genetic representations. The study aims to apply GEP to predict scour depth using parameters like clay content, water content, abutment Froude number, and bed shear strength.
Scour prediction at bridge piers in cohesive bed using gene expression progra...Mohd Danish
Accurate and reliable estimation of the scour depth at a bridge pier is essential for the safe and economical design of the bridge
foundation. The phenomenon of scour at the pier placed on sediments is extremely complex in nature. Only a limited number of
studies have been reported on local scour around bridge piers in cohesive sediment mainly due to the fact that scour modeling in
cohesive beds is relatively more complex than that in sandy beds. Recent research has made good progress in the development of
data-driven technique based on artificial intelligence (AI). It has been reported that AI-based inductive modeling techniques are
frequently used to model complex process due to their powerful and non-linear model structures and their increased capabilities
to capture the cause and effect relationship of such complex processes. Gene Expression Programming (GEP) is one of the AI
techniques that have emerged as a powerful tool in modeling complex phenomenon into simpler chromosomal architecture. This
technique has been proved to be more accurate and much simpler than other AI tools. In the present study, an attempt has been
made to implement GEP for the development of scour depth prediction model at bridge piers in cohesive sediments using
laboratory data available in literature. The present study reveals that the performance of GEP is better than nonlinear regression
model for the prediction of scour depth at piers in cohesive beds

APPLICATION OF GENE EXPRESSION PROGRAMMING IN FLOOD FREQUENCY ANALYSISMohd Danish
This document discusses different methods for flood frequency analysis, including Gumbel's method, artificial neural networks (ANN), and gene expression programming (GEP). Gumbel's method is widely used in India to predict flood peaks. ANN and GEP are artificial intelligence techniques that have been applied to hydraulic engineering problems in recent decades. The document focuses on applying GEP to flood frequency analysis of the Ganga River at Hardwar, India. GEP is implemented to derive a relationship between peak flood discharge and return period. The results of GEP are promising and suggest it is a useful alternative to more conventional flood frequency analysis methods.
3 d numerical modeling of supercritical flow in gradual expansionsPercy Rosales
This document describes a 3-D numerical model used to study supercritical flow in gradual channel expansions. The model was first verified against experimental data from a modified Rouse expansion, showing satisfactory agreement, particularly at lower Froude numbers. The model was then applied to optimize the design of a complex expansion structure with variable bottom elevation, piers, and walls. Calculations indicated flow conditions would be satisfactory if bottom ramps ensured uniform bottom variation.
This document provides an overview of digital rock technology and its industrial applications. Digital rock technology uses imaging and modeling to obtain a digital representation of a rock's pore structure and simulate fluid flow processes. It can be used to determine properties like porosity, permeability, and relative permeability. This provides similar data as traditional core analysis but with additional benefits like modeling multiple properties of the same sample simultaneously. While imaging capabilities have improved, fully modeling complex rock samples remains challenging due to limitations in resolving pore structures and simulating complex fluid-rock interactions. However, digital rock technology is becoming increasingly integrated into industry workflows for reservoir modeling and understanding fluid transport at pore scales.
This summarizes a study that applies a technique of simultaneous full-waveform inversion (FWI) of baseline and monitor seismic data with total-variation (TV) regularization of the model differences to resolve production-induced subsurface changes using field data from the Gulf of Mexico Genesis Field. The technique inverts multiple survey vintages simultaneously with TV regularization, which promotes blocky model differences and reduces oscillatory artifacts. Application to the Genesis Field data resolves negative velocity changes in the overburden associated with compaction and dilation effects from nearby reservoir production, consistent with prior time-strain estimates.

This document discusses modeling groyne placement on river bends based on sedimentation analysis using numerical simulation with the finite difference method. The goal is to determine optimal groyne placement by considering sediment accumulation volumes in groyne fields.
The study plans to simulate 450 cases combining various groyne positions, lengths, flow velocities, bend radii, and suspended sediment concentrations. Conservation equations for mass and momentum will be used to develop the mathematical model. Validation and verification processes will evaluate the agreement between experimental data and model predictions.
Regression analysis of simulation results will determine suitability coefficients to obtain relationships between parameters like Froude number and groyne length, providing guidance on best distances between groynes. The numerical model aims
Hydrocarbon potential of the Borno Basin through Electrofacies and depositional environment analysis was carried out from well log and seismic reflection data to reassess the potential of the Basin thereby justifying the huge financial commitment of the Government. The reflection configuration pattern from the seismic reflection lines is characterized by variation from parallel, continuous and strong amplitude to sub parallel, chaotic discontinuous and low amplitude which indicate a variation from a low energy basinal setting of uniform rate of continental deposition to high energy environment of monolithologic deposits. Furthermore, the derivable log signatures shows a variation from serrated mud/sand to serrated blocky to serrated funnel and bell shapes with depth. This imply a stable massive mud/sand rich basinwide environment to an upward regressive sequence of bar deposit followed by a deltaic estuarine clastic sediment to gradual upward transgressive decrease in grain size to a fluvial point bar deposit. These environments identified from the research are known to be hydrocarbon province.
This study assessed the effects of DEM gridding methods on predictions from the distributed hydrologic model MIKE SHE when modeling a 586 km2 catchment with a 600 m resolution. Three types of gridding methods were tested: 1) bilinear interpolation around grid cell peripheries, 2) bilinear interpolation around grid cell centers, and 3) TOPOGRID which considers landscape features like streams. Model calibration revealed variations in parameter values and predictions depending on the DEM. Model performance agreed best with DEMs having higher elevation and slope quality. The quality of DEMs from bilinear interpolation was poorer than from TOPOGRID.

Matthew Cahalan Georgia Water Resources Conference PresentationMatthew Cahalan
This is the poster I presented at the 2015 Georgia Water Resources Conference. It focuses on my M.S. thesis research that seeks to answer this fundamental question: "why do sinkholes form where they do?". This question was answered using an improved remote sensing sinkhole mapping procedure, integration of many datasets (i.e., hydrologic, anthropogenic, geologic, geomorphologic, and hydrogeologic), and spatial statistics (i.e., ordinary least squares and geographically weighted regression). This poster / my presentation was voted as one of the top 3 posters at the conference.
This presentation examines the suitability of using Vs30 as the basis for seismic site classification and concludes that it is about as good as we can do. However, there will be wide variation in the site responses within any one site class and it is suggested that nonlinear effective stress site responses should be conducted more routinely. Some guidance is provided on the conduct of such analyses.
Predicting (Nk) factor of (CPT) test using (GP): Comparative Study of MEPX & GN7Ahmed Ebid
Static cone penetration test (CPT) is a broadly satisfactory and dependable geotechnical in-situ apparatus that gives brisk and honest substantial measure of data about soil classification, stratification and properties. Un-drained shear strength of clay (cu) is one of the principle soil parameters that could be sensibly evaluated from the (CPT) results, as it is specifically connected to the tip resistance through the experimental cone factor (Nk). Earlier researches showed that (Nk) value depends on type of soil, nature and stress history conditions and many other variables. Construction development in some locations with thick deposits of soft to very soft clays motivates extensive researches to define the reasonable value of the (Nk) factor for such types of clay. The performed study concentrated on utilizing the genetic programming technique (GP) to predict (Nk) value of clay using the consistency limits that can be easily determined in the laboratory. A set of 102 records were gathered from the CPT site investigations and corresponding consistency limits and other physical properties experiments, were divided into training set of 72 records and validation set of 30 records. Both (GN7) & (MEPX) software were used to apply (GP) on the available data. Four trials for each software with different chromosome lengths were performed to correlate the (Nk) factor with the clay consistency limits, water content (wc) and unit weight (γ) using training data set, then, the produced relations were tested using the validation data set. The four generated formulas using (GN7) showed accuracies ranging between 93% and 97% and coefficient of determination (R2) ranging between 0.7 and 0.9, while the other four formulas form (MEPX) showed accuracy not exceeding 95% and coefficient of determination (R2) ranging between 0.45 and 0.75.
The document discusses 3D geological modeling, including defining the process as developing a mathematical representation of subsurface structures using data from boreholes, seismic surveys, and maps. It outlines the basic steps of 3D modeling as including data georeferencing, picking structural features, creating a fault network, and horizon modeling on a block-by-block basis. A case study of 3D modeling of the Brady's geothermal system in Nevada is also presented.
Improved analyses of liquefaction and settlementRobert Pyke
This is a further updated version of my presentation on the subject topic. It includes additional material on seismic settlements.

An improved method of evaluation is described and illustrated by case histories.
IRJET - Critical Appraisal on Footing Subjected to MomentIRJET Journal
This paper summarizes several studies on the moment capacity of foundations subjected to lateral loads, including experimental and numerical modeling work. Key findings include:
1) Centrifuge and numerical modeling show moment capacity increases with pier length, depth, and dense soil packing, but decreases with higher pier aspect ratios.
2) Experiments and modeling of pile groups and piled rafts found rafts increase lateral resistance over pile groups alone due to base contact pressure.
3) Testing of circular footings on clay found moment-rotation curves are nonlinear and moment limits increase with footing depth and width.
This document discusses the use of non-invasive geophysical techniques to build 3D ground models and reduce the cost and risk of site investigations. It provides examples of using techniques like MASW, CSWS, GPR to map soil properties and depth to bedrock in order to develop detailed geotechnical models. Case studies describe creating models for a sewer project in Langat, Malaysia and a landfill project in Western Australia, allowing identification of problem areas without extensive drilling and reducing costs. The document concludes that geophysical techniques provide a cheap and quick way to gather valuable site information.
Numerical simulation of laterally loaded pileDr. Naveen BP
This document presents a finite element model simulation of a lateral load test on a 1m diameter bored pile embedded in residual soils. The pile and soil were modeled in PLAXIS 2D, with the soil represented by a Mohr-Coulomb model and the pile as a beam element. The model results showed good agreement with load-displacement curves from the field test. However, the field test was unable to apply loads high enough to reach design code displacement limits due to limitations of test equipment for large piles in residual soils. The numerical model can simulate larger displacements to evaluate pile behavior under higher loads.
Multichannel analysis of surface waves Harish Parimi
Active and passive surface wave methods were used to image subsurface shear wave slowness at the Coyote Creek field site. Comparisons of slowness profiles from different methods showed generally good agreement, with most methods predicting larger near-surface slowness and smaller deep slowness compared to the reference model. Site amplification estimates based on the different slowness models were also generally similar. The blind interpretation experiment demonstrated that surface wave methods can provide robust shear wave velocity structures when multiple independent interpretations are considered.
A STUDY OF GEO-ENGINEERING PROPERTIES OF RIVER-BORNE COARSE AGGREGATES OF RIV...IAEME Publication
An attempt has been made to study the geological and engineering properties of the riverborne coarse aggregates of river Pagladia, Baksa district, Assam for evaluating their suitability as road material. The investigation were carried out on both natural and crushed form of the coarse aggregates of the river from upstream to gradually downstream to see their probable property variations. The results of various geological and engineering test performed show that both the type
of aggregates are suitable as road material as per specification laid down by Indian Standard Institutions (Bureau of Indian Standard), Indian Roads Congress and Ministry of Surface Transport and various suggestions put forward by different authors in their different publications.
Robust 3D Geological Models: Hard Data is KeyFF Explore 3D
Understanding and incorporating 2D data, whether from surface field work or underground mine mapping, should always be the starting point of an integrated and coherent 3D geologic model, especially for areas with great geometric contrasts. Without this valuable data, 3D modelling is essentially performed with blinders on, and its absence results in a model that is too theory-driven, and lacks input from geologists and “real” field data.
Three-dimensional geologic models require complete, homogeneous and valid databases. The resulting 3D models are directly based on and rely on high-quality data. The data comprises both surface and underground observations. “Raw” or “hard” data should always be assigned more weight and act as rigid control points in 3D models. Hard data should always be distinguishable from interpreted data in 3D models. Investing the necessary time to learn how to homogenize and structure raw data in a rigorous way will be paid back during the 3D interpretation process.
Once 3D models are completed, they should be used as an exploration tool, populating their cells with user-chosen properties. Both quantitative and qualitative properties can be interpolated throughout the cells of the 3D model for further querying and questioning. Thus, the extra benefit of 3D map models is their use as dynamic interactive tools to help define new mineral exploration targets at depth.
A 3D map model is not a goal but a tool that should be dynamic, modified, questioned, shared and updated. Its future usefulness is determined by how well it can be utilized by a multi-disciplinary team of geologists, geophysicists, geochemists, engineers, metallurgists and environmental experts.
1) The document describes a study applying poststack acoustic impedance inversion to characterize subsalt reservoirs using 3D seismic data from the Walker Ridge protraction area in the Gulf of Mexico.
2) Inversion of a depth-migrated seismic volume was able to derive relative acoustic impedance, which was then used with a background model to estimate absolute acoustic impedance.
3) Comparison of inverted acoustic impedance to well logs showed good agreement, indicating the potential for quantitative seismic analysis of subsalt reservoirs despite challenges of low frequencies and complex salt geometry.
Geocomposite Wick Drainage System.
Geotextile Filtration and Erosion Control
The JET Filter is a flush mount system which can be permanently installed on the front side of any earth retaining structure such as bridge abutments, sheet piling and retaining walls.
With its removable designed inner cartridge, the filter can be changed and cleaned, if needed from the front side of the earth retaining structure without dredging from behind to replace the erosion control fabric.
Arch bridges carry weight outward along a curved arch to abutments at each end, which support the load and prevent the ends from spreading. Abutments work like stacks of books that keep the ends of a curved cardboard strip from spreading when pressed down on. Beam bridges consist of a horizontal beam supported on piers at each end, with weight pushing straight down. When loaded, the top of the beam experiences compression and the bottom experiences tension.
This document provides information on different types of bridges, including their key characteristics and examples. It discusses arch bridges, girder bridges, cantilever bridges, suspension bridges, truss bridges, and prestressed concrete bridges. Specific bridges mentioned include the Tyne Bridge in the UK and the Golden Gate Bridge in California. The document also describes basic bridge engineering concepts such as compression and tension forces.

Arch bridges carry weight outward along a curved arch to abutments at each end, which support the load and prevent the ends from spreading. Abutments work like stacks of books that keep the ends of a curved cardboard strip from spreading when pressed down on. Beam bridges consist of a horizontal beam supported on piers at each end, with weight pushing straight down. When loaded, the top of the beam experiences compression and the bottom experiences tension.

Bridges provide passage over obstacles without blocking the way below. They carry traffic and loads over channels, roads, or railways. Bridges are classified based on their function, materials, form, position, construction method, and more. Common types include girder, truss, arch, cable-stayed, and suspension bridges, which vary in their typical spans and forces. Joints are often included to allow for movement from temperature changes and material shrinkage/expansion without compromising the bridge's integrity.
Segmental bridge construction involves building bridges out of precast concrete segments. This allows for longer spans than traditional methods by reducing the need for intermediate piers. There are several techniques for segmental bridge construction including cast-in-place using form travelers, incremental launching where segments are cast and then pushed out over supports, and precast segment erection using launching girders. Segmental construction enables building bridges more quickly and over existing infrastructure with minimal traffic disruptions.
The document discusses different types of bridge foundations. Shallow foundations include spread foundations and raft foundations, which are suitable for small bridges on soil with good bearing capacity. Deep foundations are needed when the bearing soil is deep below ground or water levels are high. Common deep foundation types are pile foundations, caisson foundations, and well foundations. Caisson foundations involve sinking large, reinforced concrete boxes into the ground under water. Well foundations involve constructing circular brick or stone structures that are filled with compacted soil. The type of foundation chosen depends on the subsoil conditions and hydraulic requirements at the bridge site.

This study aims to investigate the effect of single cavity when it presence at a
specific location within the homogenous soil, on the behavior of seepage and uplift
pressure under a hydraulic structure. The results are analyzed to introduce
deterministic formulae for calculating the amount of seepage and the uplift pressure
head. The work was done in three stages by using experimental investigation; the first
stage includes 36 models of 75mm in diameter cavity, while the second and the third
stages includes eight models for each with 100mm and 34mm diameter of cavity,
respectively. The results shows that, when the cavity presence at the left side its impact
was positive on the seepage behavior. While the influence was changed to a negative
impact when the cavity presence at the right side, except at some specific locations. The
statistical software has been employed to generate the two deterministic formulae, and
the results of multiple regressions are checked by statistical indices for the purpose of
recognizing the reliability of the proposed formulae.
This document summarizes a paper that evaluates the interaction of different parameters of a geofoam-filled trench barrier for mitigating ground vibrations, using response surface methodology. A numerical model was developed using Plaxis finite element software coupled with Python programming to automate parametric studies. Key parameters investigated include trench depth, width, soil layer thickness, shear wave velocity, and distance from vibration source. Results show that depth and shear wave velocity most impact barrier effectiveness. Near-field barriers perform better than far-field. Stiffer soils provide more homogeneous conditions where changing layer thickness has little effect. The interaction of location and soil properties produces complex wave interference patterns that impact screening.

ACCESS RESEARCH ARTICLE OPEN ACCES Wastewater Pipeline Design in Accordance w...IJERA Editor
After the treatment of the wastewaters, a pipeline is used to transfer the treated water from the onshore pump station to the wastewater disposal marine environment. This technique is required for the dilution process in the marine environment instead of a secondary treatment. When the pipeline design for wastewater treatment is implemented, the stability issues of the pipelines must be considered because the pipeline design is based on factors such as currents, waves, geotechnical conditions, physical properties of the water and pipe’s material characteristics. At this point, a computer program is beneficial for the quick design of wastewater pipelines. To find a suitable design under these various design limitation and factors, the algorithm of the SUbmarine Pipeline Design (SUPLID) software was developed which is powerful tool for stability analysis of the submarine pipeline against dynamic current-wave motions and foundation characteristics. The SUPLID program provides a flexible design environment for the design engineer for dimensioning and stabilizing the pipeline system with also artificial weights. In this study, the main methodology and the structure of the SUPLID program was introduced and one of its application for a typical submarine wastewater pipeline was discussed
This document summarizes a study that used computational fluid dynamics (CFD) to model soil erosion during a hole erosion test (HET). The study used the k-epsilon turbulence model in ANSYS Fluent to simulate the turbulent flow within the HET apparatus and calculate wall shear stresses. Higher velocities were found to increase erosion rates according to an erosion law relating erosion rate to shear stress exceeding a critical value. Non-uniform erosion along the hole was predicted, unlike one-dimensional models. Results provide insight into how flow variables like velocity affect internal erosion processes.

Changes in dam break hydrodynamic modelling practice - Suter et alStephen Flood
Abstract: Today, many organisations rely on hydrodynamic modelling to assess the consequences of dam break failure on downstream populations and infrastructure. The availability of finite volume shock-capturing schemes and flexible mesh schematisations in widely used software platforms imply that dam break modelling projects will be carried out differently in the future: Finite volume based platforms allow widespread application of shock-capturing methods and flexible mesh platforms can represent features in the study area more realistically and are more flexible thanks to varying mesh resolutions. Furthermore, the recent adoption of Graphics Processing Unit (GPU) technology in mainstream scientific and engineering computing will also significantly decrease computation times at relatively low cost.
This paper examines the application of finite volume, flexible mesh and GPU technologies to dam break modelling. One-dimensional (1D) modelling results are compared to those from two-dimensional (2D) finite difference and finite volume approaches. The results demonstrate that there are differences between modelling approaches and that the computational speeds of 2D simulations can be significantly reduced by the use of GPU processors.
Open channel flow velocity profiles for different reynolds numbers and roughn...eSAT Journals
Abstract A series of laboratory tests were carried out to understand the extent of effect of roughness and Reynolds number on mean velocity in both outer and inner scaling. To this end, four different types of bed surface conditions (impermeable smooth bed, impermeable rough bed, permeable sand bed and impermeable distributed roughness) and two different Reynolds number (Reh = 47,500 and 31,000) were adopted in the study. Sand particles of median diameter of 2.46 mm were used to create the roughness. The results show that the mean velocities collapsed well for different Reynolds number and for all different bed surfaces. The maximum velocity for all flow conditions were observed below some distances from the free surface. The location of maximum velocity is seen to be dependent on both of roughness and Reynolds number. The smooth bed test data agrees well with the standard log law and collapses well in viscous sub layer and overlap region. The extent of collapses is found to be dependent on Reynolds number. Friction coefficient is noted to be dependent on both the Reynolds number and roughness. Key Words: Open channel flow, Reynolds number, Roughness, mean velocity, friction coefficient, log law
This document summarizes a study that investigated the effect of roughness and Reynolds number on mean flow velocities in an open channel. Laboratory experiments were conducted in a flume with four different bed surfaces (smooth, rough with sand strips, continuous rough sand layer, permeable sand bed) and two Reynolds numbers. Laser Doppler anemometry was used to measure streamwise velocities. The results showed that mean velocities collapsed well across different bed surfaces and Reynolds numbers. Maximum velocities generally occurred below the free surface. The location of maximum velocity depended on roughness and Reynolds number. Friction coefficients were also found to depend on both roughness and Reynolds number.

ABSTRACT: In the developing countries like India, need of infrastructure is very high as compared to the available resources. The various organizations put their demands to state and center government for sanction of their project, government depends upon its various department to provide an approximate cost so that priorities can be assigned. The conventional procedure depends upon the land surveying, collection of data from various departments resulting in delay in necessary decision making or some time shelving due to unreasonable cost estimate due to field data being very old. Survey of India, The National Survey and Mapping Organization single handily taking this responsibility thus up gradation of data is far behind the actual development. From the satellite data, which is available in the form of images and terrains (even in 3d LiDAR points for some areas) is very useful for Feasibility Study, and Preliminary Project Report. In the present study natural drain named „Chai Nala‟ meanders through the prime property of Greater Mohali Area Development Authority (GMADA) thus making a big chunk of commercial land inoperative. It was proposed to straighten and channelize to reclaim the land from drain regime. Being the precious land department wanted the most economical and technically sound design without taking any risk. It was decided to counter check the hydraulic data, ground profile, acquired from the Punjab Irrigation Department with the satellite data and Differential Global Positioning System (DGPS). The data from the Google Earth was acquired using Cad Earth software and water shed analysis was carried out using Autodesk Civil 3D software. Comparison of results shows that this technique is quite useful and can be for preliminary feasibility and project preparation. Thus saving huge money and time.

Living in 21st century in itself reminds all of us the necessity of police and its administration. 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.

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.

An experiment conducted in this study found that BaSO4 changed Nylon 6's mechanical properties. By changing the weight ratios, BaSO4 was used to make Nylon 6. This Researcher looked into how hard Nylon-6/BaSO4 composites are and how well they wear. Experiments were done based on Taguchi design L9. Nylon-6/BaSO4 composites can be tested for their hardness number using a Rockwell hardness testing apparatus. On Nylon/BaSO4, the wear behavior was measured by a wear monitor, pinon-disc friction by varying reinforcement, sliding speed, and sliding distance, and the microstructure of the crack surfaces was observed by SEM. 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.

A nonlinear regression method in the MATLAB environment for the same dataset in the
present study was also implemented to get the scour depth prediction equation. It leads to the
following equation for the estimation of scour depth at the bridge abutment embedded in the bed of
the clay-sand mixture:

327 (the precision) less or equal to 0.01, then the precision is equal to zero, and fi= fmax = Ct.M. In this
case, M = 100 is used and, therefore, fmax = 1000. The advantage of this kind of fitness function is
that the system can find the optimal solution for itself [24, 25].
The second major step consists in choosing the set of terminals T and the set of functions F to
create the chromosomes. In this, the terminal set consists obviously of the independent variable(s),
(see table 2) but the choice of the appropriate function set is not so obvious, but a good guess can
always be done in order to include all the necessary functions[24, 25].
The third major step is to choose the chromosomal architecture, i.e., the length of the head
and the number of genes. A single gene and two head lengths were used initially and then, the
number of genes and heads were increased by one at a time during each run until the most
appropriate fit was obtained. It was observed that more than 7 genes and a head length greater than
twelve did not significantly improve the performance of GEP model. Thus, the head length, h = 12,
and 7 genes per chromosome were employed for the GEP model in the present study.
The fourth major step is to choose the linking function. In this study, addition was used as a
linking function and the final step is to choose the set of genetic operators that cause variation and
their rates. A combination of all genetic operators (mutation, transposition and crossover) is used for
this purpose (Table 2).
The explicit formulation of the GEP for the scour depth prediction at the bridge abutments in
the cohesive sediments has been obtained as:
