IC ENGINE TESTING
At a design and development stage an engineer would design an engine with certain aims in his mind. The aims may include the variables like indicated power, brake power,
brake specific fuel consumption, exhaust emissions, cooling of engine, maintenance free operation etc. The other task of the development engineer is to reduce the cost and
improve power output and reliability of an engine. In trying to achieve these goals he has
to try various design concepts. After the design the parts of the engine are manufactured for the dimensions and surface finish and may be with certain tolerances. In order verify the designed and developed engine one has to go for testing and performance evaluation of the engines.
Thus, in general, a development engineer will have to conduct a wide variety of engine
tests starting from simple fuel and air-flow measurements to taking of complicated
injector needle lift diagrams, swirl patterns and photographs of the burning process in
the combustion chamber. The nature and the type of the tests to be conducted depend
upon various factors, some of which are: the degree of development of the particular
design, the accuracy required, the funds available, the nature of the manufacturing
company, and its design strategy. In this chapter, only certain basic tests and
measurements will be considered.
After studying this unit, you should be able to
• understand the performance parameters in evaluation of IC engine
performance,
• calculate the speed of IC engine, fuel consumption, air consumption, etc.,
• evaluate the exhaust smoke and exhaust emission, and
• differentiate between the performance of SI engine and CI engines.

Design Optimization and Analysis of a Steam Turbine Rotor GroovesIOSR Journals
A large variety of turbo-machinery rotor groove geometries are used in industry. However, there is
no specific attempt made to compare them on the basis of performance. This paper provides an attempt to fill
that gap aiming to find an optimum geometry. The main objective of the investigations is to reduce fillet stress
concentration factor and associated deformations. The present work carries out the design modification of fillet
of a Steam Turbine Rotor. Finite Element Analysis is performed using ANSYS Workbench that is used to
determine the fillet stresses effectively to modify the blade rotor grooves. The low pressure steam turbine rotor
blades have usually a history of stress failure. They suffer from tensile and bending stresses partly due to the
centrifugal force as a result of high rotational speeds and partly due to high pressure, temperature and speed
steam loading. The centrifugal force is one of the problems that face the designers of turbine blades especially
the long ones. The designer always aims at reducing these stresses. One way to do so is by the reduction of
stress concentration factor which takes place between the rotor and its groove. That is to make the rotor blade
of variable cross section instead of straight. This paper presents the method of reducing stress concentration
factor as well as reduction in the deformation of the rotor
Thermal Analysis of Steam Turbine Power PlantsIOSR Journals
: Steam are a major energy consumer. Optimising process operating conditions can considerably
improve turbine water rate, which in turn will significantly reduce energy requirement. Various operating
parameters affect condensing and back pressure turbine steam consumption and efficiency. The industrial
sector is the largest energy consumer, accounting for about 30 % of total energy used. Fuel and energy prices
are continuously rising. With the present trend of energy prices and scarcity of hydrocarbon resources lowering
energy requirement is a top priority. Energy conservation benefits depend on the adopting minor or major
modifications and using the latest technology. Turbines are designed for a particular operating conditions like
steam inlet pressure, steam inlet temperature and turbine exhaust pressure/ exhaust vacuum, which affects the
performance of the turbines in a significant way. Variations in these parameters affects the steam consumption
in the turbines and also the turbine efficiency. The present study was done to improve the power output of the
turbine, thermal efficiency and specific steam consumption in conventional steam power plants. Three cycles i.e
regenerative cycle, superheater cycle and cogeneration cycle are considered to formulate the data and obtain a
better result in steam turbine power plants
This is a presentation of research in the field of automation of steam turbines power upon 200MW of the group of Process Automation at Institute Mihajlo Pupin, Belgrade. In short, this is a model of steam turbine, which is used during the development of control algorithms steam turbine, power plant personnel training and optimization of steam turbine operation.

Design of Industrial Electro-Hydraulic Valves, New ApproachIJERA Editor
A fully flexible valve actuation systems are being under consideration as an enabling technology for advanced internal combustion engine concepts. Electro-hydraulic valve actuator systems are being considered as a dominating variable valve technology. Compared to the servo control system, the system using a proportional valve has the advantages of low price, high anti-pollution ability and high reliability. Unlike existing electromechanical or servo actuated electro-hydraulic valve actuation systems, precise valve motion control is achieved with an internal feedback mechanism. This feedback mechanism can be turned on or off in real-time using simple two state valves which helps reduce the system cost and enables mass production.
This report gives basic knowledge about overhauling of Turbine, erection, commissioning.

A coordinated mimo control design for a power plant using improved sliding mo...ISA Interchange
For the participation of the steam power plants in regulating the network frequency, boilers and turbines should be co-ordinately controlled in addition to the base load productions. Lack of coordinated control over boiler–turbine may lead to instability; oscillation in producing power and boiler parameters; reduction in the reliability of the unit; and inflicting thermodynamic tension on devices. This paper proposes a boiler–turbine coordinated multivariable control system based on improved sliding mode controller (ISMC). The system controls two main boiler–turbine parameters i.e., the turbine revolution and superheated steam pressure of the boiler output. For this purpose, a comprehensive model of the system including complete and exact description of the subsystems is extracted. The parameters of this model are determined according to our case study that is the 320 MW unit of Islam-Abad power plant in Isfahan/Iran. The ISMC method is simulated on the power plant and its performance is compared with the related real PI (proportional-integral) controllers which have been used in this unit. The simulation results show the capability of the proposed controller system in controlling local network frequency and superheated steam pressure in the presence of load variations and disturbances of boiler.
Model-based adaptive sliding mode control of the subcritical boiler-turbine s...ISA Interchange
As higher requirements are proposed for the load regulation and efficiency enhancement, the control performance of boiler-turbine systems has become much more important. In this paper, a novel robust control approach is proposed to improve the coordinated control performance for subcritical boiler-turbine units. To capture the key features of the boiler-turbine system, a nonlinear control-oriented model is established and validated with the history operation data of a 300 MW unit. To achieve system linearization and decoupling, an adaptive feedback linearization strategy is proposed, which could asymptotically eliminate the linearization error caused by the model uncertainties. Based on the linearized boiler-turbine system, a second-order sliding mode controller is designed with the super-twisting algorithm. Moreover, the closed-loop system is proved robustly stable with respect to uncertainties and disturbances. Simulation results are presented to illustrate the effectiveness of the proposed control scheme, which achieves excellent tracking performance, strong robustness and chattering reduction.
Robust control of speed and temperature in a power plant gas turbineISA Interchange
In this paper, an H∞ robust controller has been designed for an identified model of MONTAZER GHAEM power plant gas turbine (GE9001E). In design phase, a linear model (ARX model) which is obtained using real data has been applied. Since the turbine has been used in a combined cycle power plant, its speed and also the exhaust gas temperature should be adjusted simultaneously by controlling fuel signals and compressor inlet guide vane (IGV) position. Considering the limitations on the system inputs, the aim of the control is to maintain the turbine speed and the exhaust gas temperature within desired interval under uncertainties and load demand disturbances. Simulation results of applying the proposed robust controller on the nonlinear model of the system (NARX model), fairly fulfilled the predefined aims. Simulations also show the improvement in the performance compared to MPC and PID controllers for the same conditions.
Rack And Pinion Mechanism for Continuous Variable Valve Timing of IC EnginesIJERA Editor
The valve timing is a very closely studied event and effects the performance of an IC Engine greatly with
respect to the Brake Power Produced, Volumetric Efficiency and Emissions etc. The valve event if varied and
experimented with, can result in higher efficiencies and overall improved performance of the Engine. Hence,
various researchers have attempted to temper with the valve timing and thus many Variable Valve Timing
systems have been proposed till date with many of them being implemented by various manufacturers.
However, on reviewing the presently employed systems, the lack of existence of a single system capable of
independently altering both the timing and the lift of the valves was recognized. Thus, a single system capable
of achieving the above was thought of and designed. A rack and pinion mechanism powered by a programmed
servo motor mounted vertically seemed most practical in achieving this within the size and space constraints. A
single cylinder diesel Engine was simulated with „Lotus Engine Simulation‟ software to derive the optimum
valve angles and lifts for a range of the Engine operating speed and the system was accordingly programmed
and designed to achieve them. The system was designed in „Creo‟ software and analysed correspondingly in
„Ansys‟ software and then finally assembled on a Diesel Engine in the lab.

BROAD UNEXPOSED SKILLS OF TRANSGENDER ENTREPRENEURSIAEME Publication
Since ages gender difference is always a debatable theme whether caused by nature, evolution or environment. The birth of a transgender is dreadful not only for the child but also for their parents. The pain of living in the wrong physique and treated as second class victimized citizen is outrageous and fully harboured with vicious baseless negative scruples. For so long, social exclusion had perpetuated inequality and deprivation experiencing ingrained malign stigma and besieged victims of crime or violence across their life spans. They are pushed into the murky way of life with a source of eternal disgust, bereft sexual potency and perennial fear. Although they are highly visible but very little is known about them. The common public needs to comprehend the ravaged arrogance on these insensitive souls and assist in integrating them into the mainstream by offering equal opportunity, treat with humanity and respect their dignity. Entrepreneurship in the current age is endorsing the gender fairness movement. Unstable careers and economic inadequacy had inclined one of the gender variant people called Transgender to become entrepreneurs. These tiny budding entrepreneurs resulted in economic transition by means of employment, free from the clutches of stereotype jobs, raised standard of living and handful of financial empowerment. Besides all these inhibitions, they were able to witness a platform for skill set development that ignited them to enter into entrepreneurial domain.

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.

ATTRITION IN THE IT INDUSTRY DURING COVID-19 PANDEMIC: LINKING EMOTIONAL INTE...IAEME Publication
Globally, Millions of dollars were spent by the organizations for employing skilled Information Technology (IT) professionals. It is costly to replace unskilled employees with IT professionals possessing technical skills and competencies that aid in interconnecting the business processes. The organization’s employment tactics were forced to alter by globalization along with technological innovations as they consistently diminish to remain lean, outsource to concentrate on core competencies along with restructuring/reallocate personnel to gather efficiency. As other jobs, organizations or professions have become reasonably more appropriate in a shifting employment landscape, the above alterations trigger both involuntary as well as voluntary turnover. The employee view on jobs is also afflicted by the COVID-19 pandemic along with the employee-driven labour market. So, having effective strategies is necessary to tackle the withdrawal rate of employees. By associating Emotional Intelligence (EI) along with Talent Management (TM) in the IT industry, the rise in attrition rate was analyzed in this study. Only 303 respondents were collected out of 350 participants to whom questionnaires were distributed. From the employees of IT organizations located in Bangalore (India), the data were congregated. A simple random sampling methodology was employed to congregate data as of the respondents. Generating the hypothesis along with testing is eventuated. The effect of EI and TM along with regression analysis between TM and EI was analyzed. The outcomes indicated that employee and Organizational Performance (OP) were elevated by effective EI along with TM.
INFLUENCE OF TALENT MANAGEMENT PRACTICES ON ORGANIZATIONAL PERFORMANCE A STUD...IAEME Publication
By implementing talent management strategy, organizations would have the option to retain their skilled professionals while additionally working on their overall performance. It is the course of appropriately utilizing the ideal individuals, setting them up for future top positions, exploring and dealing with their performance, and holding them back from leaving the organization. It is employee performance that determines the success of every organization. The firm quickly obtains an upper hand over its rivals in the event that its employees having particular skills that cannot be duplicated by the competitors. Thus, firms are centred on creating successful talent management practices and processes to deal with the unique human resources. Firms are additionally endeavouring to keep their top/key staff since on the off chance that they leave; the whole store of information leaves the firm's hands. The study's objective was to determine the impact of talent management on organizational performance among the selected IT organizations in Chennai. The study recommends that talent management limitedly affects performance. On the off chance that this talent is appropriately management and implemented properly, organizations might benefit as much as possible from their maintained assets to support development and productivity, both monetarily and non-monetarily.
A STUDY OF VARIOUS TYPES OF LOANS OF SELECTED PUBLIC AND PRIVATE SECTOR BANKS...IAEME Publication
Banking regulations act of India, 1949 defines banking as “acceptance of deposits for the purpose of lending or investment from the public, repayment on demand or otherwise and withdrawable through cheques, drafts order or otherwise”, the major participants of the Indian financial system are commercial banks, the financial institution encompassing term lending institutions. Investments institutions, specialized financial institution and the state level development banks, non banking financial companies (NBFC) and other market intermediaries such has the stock brokers and money lenders are among the oldest of the certain variants of NBFC and the oldest market participants. The asset quality of banks is one of the most important indicators of their financial health. The Indian banking sector has been facing severe problems of increasing Non- Performing Assets (NPAs). The NPAs growth directly and indirectly affects the quality of assets and profitability of banks. It also shows the efficiency of banks credit risk management and the recovery effectiveness. NPA do not generate any income, whereas, the bank is required to make provisions for such as assets that why is a double edge weapon. This paper outlines the concept of quality of bank loans of different types like Housing, Agriculture and MSME loans in state Haryana of selected public and private sector banks. This study is highlighting problems associated with the role of commercial bank in financing Small and Medium Scale Enterprises (SME). The overall objective of the research was to assess the effect of the financing provisions existing for the setting up and operations of MSMEs in the country and to generate recommendations for more robust financing mechanisms for successful operation of the MSMEs, in turn understanding the impact of MSME loans on financial institutions due to NPA. There are many research conducted on the topic of Non- Performing Assets (NPA) Management, concerning particular bank, comparative study of public and private banks etc. In this paper the researcher is considering the aggregate data of selected public sector and private sector banks and attempts to compare the NPA of Housing, Agriculture and MSME loans in state Haryana of public and private sector banks. The tools used in the study are average and Anova test and variance. The findings reveal that NPA is common problem for both public and private sector banks and is associated with all types of loans either that is housing loans, agriculture loans and loans to SMES. NPAs of both public and private sector banks show the increasing trend. In 2010-11 GNPA of public and private sector were at same level it was 2% but after 2010-11 it increased in many fold and at present there is GNPA in some more than 15%. It shows the dark area of Indian banking sector.

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.

Courier management system project report.pdfKamal Acharya
It is now-a-days very important for the people to send or receive articles like imported furniture, electronic items, gifts, business goods and the like. People depend vastly on different transport systems which mostly use the manual way of receiving and delivering the articles. There is no way to track the articles till they are received and there is no way to let the customer know what happened in transit, once he booked some articles. In such a situation, we need a system which completely computerizes the cargo activities including time to time tracking of the articles sent. This need is fulfilled by Courier Management System software which is online software for the cargo management people that enables them to receive the goods from a source and send them to a required destination and track their status from time to time.

To increase the thermal efficiency in applications, steam turbines consist of multistage
steam expansion made practical by use of tandem-compound turbines. In a tandem
compound turbine, the sections are all on one shaft, with a single generator whereas
for cross compound turbines there are multiple shafts where generators are connected
to each. A stationary set of blades (called nozzles) and a moving set of adjacent blades
(called buckets or rotor blades) installed within a casing work together to turn the
shaft of the turbine and the connected load and so speed control is made by
controlling the inlet steam pressure.
Various control techniques were proposed in steam turbine speed control system.
In [3] the behavior of the shaft torque is simulated with isolated load and proportional
control algorithm but with a simplified first order system. Adaptation of PID
Controller using AI Technique like fuzzy logic, Particle Swarm Optimization (PSO),
Genetic Algorithm (GA), Bacterial Particle Swarm Optimization (BPSO) and Neuro
fuzzy controller(ANFIS) for Speed Control of Isolated Steam Turbine was the work
done by Mohamed .M. Ismail [4]. The turbine is considered just as a first order
system along with an electro-hydraulic governor. In the work by Dr. M Sai Veerraju
and S K Mabhujani [5] general model for power plant with fuzzy PID, ANFIS and
neural network control system is built for power system dynamic analysis. The
responses are compared for system frequency stability.
Sanjay Kr. Singh, 2013 in their study [6] focuses on multi-objective optimization
of the PID controllers for optimal speed control for an isolated steam turbine. In
complex operations, optimal tuning plays an imperative role in maintaining the
product quality and process safety. This study focuses on the comparison of the
optimal PID tuning using Multi-objective Genetic Algorithm against normal genetic
algorithm and Ziegler Nichols methods for the speed control of an isolated steam
turbine. Isolated steam turbine not being connected to the grid; hence is usually used
in refineries as steam turbine, where a hydraulic governor is used for the speed
control.
Ali Chaibakhsh et. al. [7] in their paper characterized the transient dynamics of
steam turbines subsections. In 2013 Lukáš Hubka and Petr Školník presented a paper
[8] which describes a possible way to build a simulation model of the most important
part of a power plant – the turbine with reheating section.
In this paper, Model Reference Adaptive Controller is designed for speed control
of tandem compound reheat steam turbine based on Lyapunov rule.
The structure of this paper is as follows. Section II describes about speed control
in steam turbine. The linear mathematical modelling of steam turbine is explained in
section III. Section IV discuses about Model Reference Adaptive Control (MRAC)
and the designing of Feedback, PI, and PID controllers for steam turbine speed
control system using MRAC based on Lyapunov rule. Simulation results is given in
section V. Conclusion and future scope is discussed in section VI and VII
respectively.
2. SPEED CONTROL IN STEAM TURBINE
The speed control of turbine is to protect the turbine from over speeding, since
applications like generators require precise speed control. The safety control element
on a turbine is the steam supply valve present in the steam chest after boiler and
reheater section. This safety valve can be a separate on/off valve or the shut-off
function can be incorporated into the controls of the steam supply valve that is used
for speed control.

with respect to the error. The parameter adjustment mechanism can be gradient
method or by using stability theory [2].
A stable closed loop system cannot be guaranteed by MIT rule so Lyapunov rule
is presented which is a more powerful theorem to design adaptive controllers. If there
exists a function V, that is positive definite such that its derivative along the solution
is negative semi definite, then the solution is stable. If derivative is negative definite,
then solution is asymptotically stable. This function V is called a Lyapunov function
for the system.

6. CONCLUSIONS
This paper described the MRAC controller for steam generating unit to avoid the
frequency fluctuation and response speed specifications. Feedback, PI and PID
controller was designed and evaluated through computer simulation. The tracking
capability and steady state response is examined. The adaptation gains are responsible
to improve the transient performance of the speed response in terms of rise time,
overshoot, settling time for step speed response.

7. FUTURE SCOPE
This paper investigated the linear modelling of tandem compound steam turbine,
future work can be done including the non-linearities in the system which arise some
errors and it can be eliminated by use of the same Lyapunov rule.
