Electrical circuits have basic components like switches, loads, hot and neutral wires. Voltage is electrical pressure that can be alternating current (AC) or direct current (DC), while current is the flow of electrons measured in amps. Resistance is a component's opposition to current flow and is measured in ohms. Common electrical measurements include voltage, current, resistance, frequency, and temperature. Digital multimeters are typically used to measure these components and ensure circuits are functioning properly.
The document discusses analog ohmmeters and multimeters. It describes how an ohmmeter uses a low-current source to measure resistance through a mechanical movement. Analog multimeters also use a mechanical movement to measure voltage, current, and resistance by changing the circuit connections. The document outlines some limitations of analog meters, such as reliance on stable battery voltage and nonlinear scales. It then describes how digital multimeters digitally display measurements and are now more common, though analog meters are still sometimes preferable for monitoring rapidly changing values.

Resistance is a component's opposition to current flow and is measured in ohms. Common electrical measurements include voltage, current, resistance, frequency, and temperature. Digital multimeters are typically used to measure these components and ensure circuits are functioning properly.
The document discusses analog ohmmeters and multimeters. It describes how an ohmmeter uses a low-current source to measure resistance through a mechanical movement. Analog multimeters also use a mechanical movement to measure voltage, current, and resistance by changing the circuit connections. The document outlines some limitations of analog meters, such as reliance on stable battery voltage and nonlinear scales. It then describes how digital multimeters digitally display measurements and are now more common, though analog meters are still sometimes preferable for monitoring rapidly changing values.
A digital multimeter (DMM) is an electronic instrument that measures voltage, current, and resistance. A DMM displays measurements digitally and can measure AC and DC voltage, AC and DC current, and resistance. It may also have features to measure frequency, temperature, capacitance, continuity, and diode performance. A DMM uses symbols on its front panel to indicate the measurement units. DMM specifications include the number of display digits, measurement accuracy, and voltage/current ranges and resolutions. DMMs are used to troubleshoot circuits by measuring voltage, current, and resistance. True RMS DMMs provide accurate measurements of non-sinusoidal waveforms.

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.

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.

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.

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.

Road construction is not as easy as it seems to be, it includes various steps and it starts with its designing and
structure including the traffic volume consideration. Then base layer is done by bulldozers and levelers and after
base surface coating has to be done. For giving road a smooth surface with flexibility, Asphalt concrete is used.
Asphalt requires an aggregate sub base material layer, and then a base layer to be put into first place. Asphalt road
construction is formulated to support the heavy traffic load and climatic conditions. It is 100% recyclable and
saving non renewable natural resources.
With the advancement of technology, Asphalt technology gives assurance about the good drainage system and with
skid resistance it can be used where safety is necessary such as outsidethe schools.
The largest use of Asphalt is for making asphalt concrete for road surfaces. It is widely used in airports around the
world due to the sturdiness and ability to be repaired quickly, it is widely used for runways dedicated to aircraft
landing and taking off. Asphalt is normally stored and transported at 150’C or 300’F temperature

Applications of artificial Intelligence in Mechanical Engineering.pdfAtif Razi
Historically, mechanical engineering has relied heavily on human expertise and empirical methods to solve complex problems. With the introduction of computer-aided design (CAD) and finite element analysis (FEA), the field took its first steps towards digitization. These tools allowed engineers to simulate and analyze mechanical systems with greater accuracy and efficiency. However, the sheer volume of data generated by modern engineering systems and the increasing complexity of these systems have necessitated more advanced analytical tools, paving the way for AI.
AI offers the capability to process vast amounts of data, identify patterns, and make predictions with a level of speed and accuracy unattainable by traditional methods. This has profound implications for mechanical engineering, enabling more efficient design processes, predictive maintenance strategies, and optimized manufacturing operations. AI-driven tools can learn from historical data, adapt to new information, and continuously improve their performance, making them invaluable in tackling the multifaceted challenges of modern mechanical engineering.

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODELijaia
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.

I.P.S. Ahuja and J.S. Khamba [3] have suggested that OEE is an all-inclusive benchmarking tool that serves to
gauge the various subcomponents of the manufacturing process (i.e., availability, performance and quality) and used to
measure actual improvements on 5S, Lean Manufacturing, TPM, Kaizen and Six Sigma. Benchmarking overall
equipment effectiveness can facilitate an organization to realization of zero breakdown, zero defect, zero machine
stoppage, zero accidents, zero pollution, which serve as the ultimate objective of TPM. When using OEE with these
management systems the benefits become tangible and noteworthy.
A.J.de Ron and J.E. Rooda [4] have stated that, manufactured goods are a result of a complex production
process and without the proper measuring tools and formula, the business can be expected to run blindly even in the light
of day. Having the right metrics, OEE provides a window to analyse out-of-the-ordinary issues and gives an established
framework for improving the entire manufacturing process. They further announce that a key performance measure in
mass production environments is OEE.
Bulent Dal et al. [5], suggest that the OEE measure can be applied at several different levels within a
manufacturing environment. Firstly, OEE can be used as a “benchmark”' for measuring the initial performance of a
manufacturing plant in its entirety. In this manner the initial OEE measure can be compared with future OEE values, thus
quantifying the level of improvement made. Secondly, an OEE value, calculated for one manufacturing line, can be used
to compare line performance across the factory, thereby highlighting any poor line performance. Thirdly, if the machines
process work individually, an OEE measure can identify which machine performance is worst, and therefore indicate
where to focus TPM resources.
Christian N. Madu [6] shows that equipment maintenance and reliability management are importantly associated
with an organization’s competitiveness and must be given adequate attention in the organization's strategic planning.
OEE is an effective way of analysing the efficiency of a single machine or an integrated machinery system. However,
Alok Mathur et al. [7] implies that the most important objective of OEE is not to get an optimum measure, but to get a
simple measure that tells production personnel where to spend their improvement resources. The greatest contribution of
OEE is that it is a simple, but still comprehensive, measure of internal efficiency and that it can work as an important
indicator of the continuous improvement process.
3. OVERALL EQUIPMENT EFFECTIVENESS (OEE) MEASUREMENT
In this section, the measurement of OEE for the selected critical equipments is presented.
OEE combines the operation, maintenance and management of manufacturing equipment and resources. It takes
the most common and important sources of productivity loss, which are called six big losses, shown in Fig. 1. These
losses are quantified as Availability (A), Performance (P) and Quality (Q) in order to estimate OEE and OEE calculation
is given by:
OEE = Availability × Performance × Quality
According to Nakajima [1] the ideal conditions are: Availability…..greater than 90%, Performance
Efficiency…… greater than 95%, Rate of Quality products …… greater than 99%. Therefore, the ideal OEE should be
85+ %. However, literature survey indicates that the exact definition of OEE differs between applications and various
authors. For an organization, wishing to measure their OEE, the differences in various approaches of calculating OEE
parameters (A, P, Q) could be significant in terms of OEE resultant figures.

This section presents the overall profile of the samples, descriptive statistics and frequency distribution. The
results of statistical methods of descriptive statistics, One way Anova, Scheffe’s post hoc test are tabulated in Table 1.
Here we have grouped the machines with similar criticality as Machine 1 and Machine 2. Hence Banbury of
Tyre industry and Straddle Facing of Automobile industry fall under Machine 1 and 4 Roll Calender Machine of Tyre
industry and Centerless Grinding of Automobile industry fall under Machine 2.

One way ANOVA revealed a highly significant difference between 2 companies in their mean overall
equipment effectiveness scores with F value of 368062E+14 and significance (P) of .000. Further, Scheffe’s Post hoc test
indicated that Tyre industry has maximum overall equipment effectiveness (mean 90.68%), followed by Automobile
industry (mean 60.66%).
Overall equipment effectiveness of Machine 2
One way ANOVA revealed a highly significant difference between 2 companies in their mean overall
equipment effectiveness scores with F value of 355597E+14 and significance (P) of .000. Further, Scheffe’s Post hoc test
indicated that Tyre industry has maximum overall equipment effectiveness (mean 90.4%) and overall equipment
effectiveness for Automobile industry is found to be less (mean 60.7%).
5. CONCLUSION
The study highlights the accurate estimation of equipment effectiveness that affects the productivity of the
organization. As seen from the OEE computation of the equipments, accurate performance measure of the equipment was
obtained if all six major losses were considered while computing the three OEE elements Viz., Availability, Performance
and Quality Rate. Since Total Productive Maintenance tries to reduce the losses, OEE of critical machines was found to
be high in Tyre industry which has implemented TPM to full extent and less in Automobile industry which has partially
implemented TPM. It is also found that there are many differing methods of collecting data for the six big losses, and
therefore computation of OEE also varies from one organization to another. However, the quality of data collection
determines the accuracy of OEE.
