Fiber-filled plastic materials are commonly used in metal replacement applications. The combination of low weight and high stiffness makes fiber-filled plastics ideal for high-performance applications. The key to unlocking the potential of these plastics lies in the orientation of the fibers. The orientation direction and the degree of orientation of the fibers determine the mechanical properties of the molded part. The injection moluding process for fiber-filled parts can cause great
variation in strength throughout a part, the effects of the injection process should be considered in the design of such a part.
This document discusses optimization of clearance in sheet metal blanking processes. It investigates how parameters like clearance, tool wear, and sheet thickness affect blanking results. The blanking process is modeled using finite element analysis and design of experiments to understand interactions. An optimum clearance is defined as the point where the crack propagation direction coincides with the diagonal line between punch and die contact points, resulting in clean separation. The document outlines algorithms to predict blanking forces, crack initiation and geometry based on clearance and other factors.
Experimental investigations of milling on fiber compositesIRJET Journal
This document summarizes an experimental investigation into milling fiber composites. The study examined how milling speed, feed rate, and depth of cut influence cutting forces like thrust and torque. Experiments were conducted on carbon fiber reinforced polymer composites with fiber orientations of 0, 45, 90, and 135 degrees relative to the tool motion. Results showed that fiber failure mechanisms depend on orientation, with crushing failure at 45 and 90 degrees producing higher forces than bending failure at 0 and 135 degrees. Chip morphology and delamination patterns supported the proposed failure modes. The research provides insight into fiber failure during milling of composites to optimize machining parameters.
ANALYSIS OF PROCESS PARAMETERS IN MILLING OF GLASS FIBRE REINFORCED PLASTIC C...IAEME Publication
Milling is one of the most important machining processes in manufacturing parts made out
of FRPs. Milling is a very versatile process capable of producing simple two dimensional flat
shapes to complex three dimensional interlaced surface configurations, in which a rotating,
multi-tooth cutter removes material while traveling along various axes with respect to the work
piece. However, unlike the milling of metals which is characterized by high material removal
rates, milling of FRPs is conducted at much lower scale. The reason for this is that FRP
components are largely made near net shape and any subsequent milling is limited mainly tode-burring and trimming as well as to achieving contourshapeaccuracy. Milling compositematerials are significantly affected by the tendency of these materials to delaminate under the
action of machining forces, cutting force, feed force and depth force respectively.Quality surface milling of Glass Fibre reinforced Plastic materials present variety ofissues, such milling is one of the foremost oftentimes used material removal processes in
machining of FRPs to produce a well-defined surface finish and has surface delaminationrelated to the characteristics of the material and therefore the cutting parameters used. Thesurface quality and dimensional precision greatly have an effect on the elements throughout

Synthesis of composite polymer for industrial applicationeSAT Journals
Abstract The Method of Fused Deposition Modelling is most popular rapid prototyping process producing parts layer by layer which is mainly made up of polymer. But the use of these parts is restricted because of low strength of plastic. To achieve efficient mechanical properties, metal composite polymer can be used which has not been used as feedstock material in FDM. Plastic component are most commonly produced by injection molding process. Wide variety of shapes and sizes of thin walled plastic parts are manufactured by this method . The aim of present study was to fabricate new metal composite and to investigate the effect of addition of metal powder on strength of polymer. As both FDM and Injection moulding are similar process the feasibility of metal composite feedstock was checked in injection moulding process. Experiments were carried out on parts produces by injection moulding process with different composition of metal and polymer. Six specimens with different proportions of aluminum and copper in polymer by weight were prepared as per the ASTM standard for Tensile and Flexural test. It can be concluded that addition of copper increases tensile strength of parts and aluminum increases bending strength of parts produced by Injection Moulding process.

INFLUENCE MECHANISM OF THICKNESS AND VISCOSITY OF FLAT ENERGY DIRECTOR TO THE...adeij1
The research in this paper is an essential part of a bigger effort to develop ultrasonic welding using flat energy directors (FED) in thermoplastic composites. It mainly focused on assessing the effect of the changes in thickness and viscosity of FED on welding strength and welding strength stability. Furthermore, the welding and failure mechanisms were investigated by monitoring the real-time temperature evolution at the interface and analyzing the welding area (WA) and the macro and
microfracture surface. From the experimental results, the use of FED with thinner thickness (0.1-0.2 mm) and slightly higher viscosity greatly improved weld strength and weld strength stability. Due to the effect of glass fibers forming a mechanical interlocking effect between the adherend and FED, joints with 20% SGF/PP FED also had a surprisingly excellent weld quality. Welding area analysis indicated a significantly positive correlation between the lap shear strengthⅠand the welded area for the joints with FED. Based on real-time temperature curves, thinner FED had an improvement on the initial temperature
rate and the most temperature curves leveled off at the onset melting temperature (Tonset) of the FED after a time-lapse of about 0.4 s. Morphology analysis showed that the melting and flow of matrix at the interface started at the edges of the overlap; the melting area and morphology of the interfaces with 1% EG/PP FED and 20% SGF/PP are much bigger and coarse. And failure mechanisms of the joints with FED are a combination of adhesive failure, cohesive failure, and fiber-matrix debonding failure.

Experimental investigation and analysis of mechanical properties of injectionIAEME Publication
The document experimentally investigates the mechanical properties of injection molded jute and glass fiber reinforced hybrid polypropylene composites. Composites with varying weight percentages of jute and glass fibers were tested for tensile, flexural, impact and hardness properties. The results showed that all the mechanical properties increased with increasing glass fiber content, as glass fibers have better adhesion to the matrix and higher strength than jute fibers. SEM images showed glass fibers fracturing and pulling out, along with jute fiber pull-out, under applied loads. The hybrid composites thus require greater forces to fail due to the combined effects of different fiber types.

Experimental investigation and analysis of mechanical properties of injectionIAEME Publication
The document experimentally investigates the mechanical properties of injection molded jute and glass fiber reinforced hybrid polypropylene composites. Composites with varying weight percentages of jute and glass fibers were tested for tensile, flexural, impact and hardness properties. The results showed that all the mechanical properties increased with increasing glass fiber content, as glass fibers have better adhesion to the matrix and higher strength than jute fibers. SEM images showed glass fibers fracturing and pulling out, along with jute fiber pull-out, under applied loads. The hybrid composites thus require greater forces to fail due to the combined effects of different fiber types.

of FRP composite materials. This paper also comprehensively addresses the success and
the failures of drilling operations, the factors associated with the drilling operation, their
impact on the various output parameters. In addition, this review paper also discusses

A STUDY ON THE IMPACT OF ORGANIZATIONAL CULTURE ON THE EFFECTIVENESS OF PERFO...IAEME Publication
The main objective of this study is to analyze the impact of aspects of Organizational Culture on the Effectiveness of the Performance Management System (PMS) in the Health Care Organization at Thanjavur. Organizational Culture and PMS play a crucial role in present-day organizations in achieving their objectives. PMS needs employees’ cooperation to achieve its intended objectives. Employees' cooperation depends upon the organization’s culture. The present study uses exploratory research to examine the relationship between the Organization's culture and the Effectiveness of the Performance Management System. The study uses a Structured Questionnaire to collect the primary data. For this study, Thirty-six non-clinical employees were selected from twelve randomly selected Health Care organizations at Thanjavur. Thirty-two fully completed questionnaires were received.
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.

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%.

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.

Gas agency management system project report.pdfKamal Acharya
The project entitled "Gas Agency" is done to make the manual process easier by making it a computerized system for billing and maintaining stock. The Gas Agencies get the order request through phone calls or by personal from their customers and deliver the gas cylinders to their address based on their demand and previous delivery date. This process is made computerized and the customer's name, address and stock details are stored in a database. Based on this the billing for a customer is made simple and easier, since a customer order for gas can be accepted only after completing a certain period from the previous delivery. This can be calculated and billed easily through this. There are two types of delivery like domestic purpose use delivery and commercial purpose use delivery. The bill rate and capacity differs for both. This can be easily maintained and charged accordingly.
Prediction of Electrical Energy Efficiency Using Information on Consumer's Ac...PriyankaKilaniya
Energy efficiency has been important since the latter part of the last century. The main object of this survey is to determine the energy efficiency knowledge among consumers. Two separate districts in Bangladesh are selected to conduct the survey on households and showrooms about the energy and seller also. The survey uses the data to find some regression equations from which it is easy to predict energy efficiency knowledge. The data is analyzed and calculated based on five important criteria. The initial target was to find some factors that help predict a person's energy efficiency knowledge. From the survey, it is found that the energy efficiency awareness among the people of our country is very low. Relationships between household energy use behaviors are estimated using a unique dataset of about 40 households and 20 showrooms in Bangladesh's Chapainawabganj and Bagerhat districts. Knowledge of energy consumption and energy efficiency technology options is found to be associated with household use of energy conservation practices. Household characteristics also influence household energy use behavior. Younger household cohorts are more likely to adopt energy-efficient technologies and energy conservation practices and place primary importance on energy saving for environmental reasons. Education also influences attitudes toward energy conservation in Bangladesh. Low-education households indicate they primarily save electricity for the environment while high-education households indicate they are motivated by environmental concerns.

Comparative analysis between traditional aquaponics and reconstructed aquapon...bijceesjournal
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.
