This document summarizes a study on the effects of spiral grooves in the piston bowl on exhaust emissions from a direct injection diesel engine. Three spiral grooves were cut into the inner surface of the piston bowl, slightly increasing the bowl diameter. Testing found this modified piston reduced NOx emissions by 8.82% and fuel consumption by 0.1 kg/hour compared to the standard piston at full engine load. Carbon monoxide was also reduced by 7.7%, while exhaust gas temperature decreased by 4.8 degrees Celsius. The spiral grooves enhanced swirling flow in the combustion chamber for better air-fuel mixing, lowering emissions while maintaining brake thermal efficiency.
This document summarizes a study on controlling aldehyde emissions from a 4-stroke spark ignition engine using methanol-blended gasoline with an improved catalytic converter design.

Results showed that the copper coated chamber and catalytic converter with air injection reduced aldehyde emissions more effectively than other configurations tested.
The document discusses the effect of varying piston bowl geometry and hydrogen addition on the performance and combustion characteristics of a diesel engine. Experiments were conducted on a single cylinder diesel engine operated with diesel alone and with hydrogen added at various flow rates. Two piston bowl geometries - hemispherical and toroidal - were tested. Results showed that adding hydrogen up to 6 L/min improved brake thermal efficiency, brake specific fuel consumption, exhaust gas temperature, heat release rate, and cylinder pressure compared to diesel alone. The toroidal piston bowl geometry further improved these parameters compared to the standard hemispherical geometry. Above 6 L/min hydrogen flow, knocking was observed due to higher combustion temperatures.

The dual plug engine was developed by introducing a second spark plug opposite the first plug. Experiments were conducted at different loads and compression ratios. Results showed the dual plug engine had better thermal efficiency, lower HC and CO emissions, but slightly higher NOx emissions than the single plug engine. The effect of compression ratio on the dual plug engine was also investigated, finding an optimum ratio for best performance and emissions.
This document summarizes a study on exhaust emissions from a four-stroke spark ignition engine operating on gasohol (ethanol blended with gasoline) with two different engine configurations: a conventional engine and one with a copper-coated combustion chamber.

Exhaust emissions of carbon monoxide and unburnt hydrocarbons were measured at various engine loads. The copper-coated engine configuration and use of the catalytic converter both reduced exhaust pollutants compared to the conventional engine operating on pure gasoline without a catalytic converter. Further reductions were seen when air was injected into the catalytic converter.

3) Advancing injection timing reduced particulate concentration at high injection pressure by allowing more time for oxidation, but had varying effects at low pressure due to competing effects on mixing time and droplet size.
This document discusses a new technology called Rainbow Technology that allows large amounts of data to be stored on ordinary paper. It describes how audio and text files can be converted to grayscale images and printed on paper. By scanning the printed paper, the data can be reconstructed back into the original files. The key advantages are that paper is very low-cost compared to storage devices like CDs and is biodegradable. It also describes how the technology works by encoding and decoding the data files into and out of the grayscale images.
Rainbow technology is a paper-based storage technique that can store up to 450GB of data. It works by encoding files into colored geometric shapes printed onto paper at high density. Data is represented by colors rather than binary 1s and 0s. The process involves converting data bits into values, then pictures, with error correction added. Data retrieval reverses this process. Advantages include extremely low cost and biodegradability, while disadvantages are potential for data loss from fading or damage. Future applications could include high capacity paper cards and replacements for CD/DVD drives.

The document describes rainbow technology, which enables massive data storage through encoding files as colored geometric shapes printed on paper. It can store up to 450GB on an ordinary sheet of paper by representing data as circles, triangles, and squares encoded in various color combinations.

The document describes a proposed new data storage technology called "Rainbow Technology" that claims to be able to store up to 450 GB of data on an ordinary sheet of paper. It would represent data using colored geometric shapes rather than binary and could store around 2.7 GB per square inch when printed at high resolution. However, experts are skeptical because the claimed storage densities would require unprecedented compression or capabilities beyond current printing and scanning technologies. If proven, Rainbow Technology could provide an extremely low-cost and environmentally friendly alternative to DVDs and hard drives.

- The study examined exhaust emissions from a diesel engine with a ceramic-coated cylinder head (low-grade low heat rejection combustion chamber) fueled with cottonseed biodiesel under various operating conditions.
- Particulate emissions decreased and NOx levels increased with the low heat rejection combustion chamber compared to a conventional engine, due to improved combustion. Biodiesel also reduced particulate emissions but increased NOx levels over diesel.
- Preheating the biodiesel reduced both particulate emissions and NOx emissions in both combustion chamber types by improving fuel properties. Higher injector opening pressure generally improved emissions by enhancing atomization and air-fuel mixing.

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.

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.

Home security is of paramount importance in today's world, where we rely more on technology, home
security is crucial. Using technology to make homes safer and easier to control from anywhere is
important. Home security is important for the occupant’s safety. In this paper, we came up with a low cost,
AI based model home security system. The system has a user-friendly interface, allowing users to start
model training and face detection with simple keyboard commands. Our goal is to introduce an innovative
home security system using facial recognition technology. Unlike traditional systems, this system trains
and saves images of friends and family members. The system scans this folder to recognize familiar faces
and provides real-time monitoring. If an unfamiliar face is detected, it promptly sends an email alert,
ensuring a proactive response to potential security threats.

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.

Supermarket Management System Project Report.pdfKamal Acharya
Supermarket management is a stand-alone J2EE using Eclipse Juno program.
This project contains all the necessary required information about maintaining
the supermarket billing system.
The core idea of this project to minimize the paper work and centralize the
data. Here all the communication is taken in secure manner. That is, in this
application the information will be stored in client itself. For further security the
data base is stored in the back-end oracle and so no intruders can access it.
Height and depth gauge linear metrology.pdfq30122000
Height gauges may also be used to measure the height of an object by using the underside of the scriber as the datum. The datum may be permanently fixed or the height gauge may have provision to adjust the scale, this is done by sliding the scale vertically along the body of the height gauge by turning a fine feed screw at the top of the gauge; then with the scriber set to the same level as the base, the scale can be matched to it. This adjustment allows different scribers or probes to be used, as well as adjusting for any errors in a damaged or resharpened probe.
