In this paper, PIC microcontroller was designed to develop a satellite dish positioning system which can be operated by using a remote control. The main point of using a dish is to receive signal from satellites and other broadcasting sources. In order to get the exact angle of position of the dish, it needs to be adjusted manually. In order to overcome the difficulty of adjusting manually, this paper helps in adjusting the position of the dish through a remote control. Remote control acts as a transmitter whose data is received by an IR receiver which is interfaced to a microcontroller of PIC 16F877A. The remote control sends coded data to the receiver whose output is then sent to the microcontroller.

A circuit was designed using an AT89C51 microcontroller, L293D motor driver, TSOP1738 IR receiver, and two geared motors. The TSOP1738 receives IR signals from the TV remote based on the RC5 protocol and sends data to the microcontroller. The microcontroller then controls the motors via the L293D to position the dish antenna horizontally and vertically based on the remote button pressed. The project aims to allow remote control of a dish antenna for applications such as DTH reception.

Modeling of DC Motor and Choosing the Best Gains for PID Controllerijtsrd
This document summarizes research on modeling a DC motor and using a PID controller to control its position. The researchers modeled the motor mathematically in two ways: by estimating parameters like resistance, inductance, torque constant, and back EMF constant; and based on the motor's first-order speed response curve.

Ziegler-Nichols tuning methods and MATLAB simulations were used to select PID gains for position control. Results showed the PID controller could accurately control the motor's angle based on feedback from an optical encoder. The controlled DC motor could then be applied to positions systems like a robot arm.

The command signals are generated from these gestures using accelerometer sensing [1]. These signals are then passed to the robot to navigate it in the specified directions.
Autonomous Terrain Mapping Using COTS HardwareJames Anderson
Undergraduate paper submission for 2012 International Telemetering Conference
Abstract: The paper describes the development of a robotic platform which can autonomously map terrain using a COTS infrared imaging and ranging system. The robotic system is based on an omni-directional platform, and can navigate typical commercial indoor environments. An on-board processor performs surface reconstruction, and condenses the point clouds generated by the ranging system to mesh models which can be more easily stored and transmitted. The processor then correlates new frames with the existing world model by using sensor odomerty. The robot will autonomously determine the best areas of the environment to map, and gather complete three dimensional color models of arbitrary environments.
Fresnel lens and tracking to improve the solar panel efficiencyIAEME Publication
This document summarizes a study on improving solar panel efficiency through the use of a sun-tracking system and Fresnel lens. A microcontroller-based system was designed to track the sun's movement using light sensors and motors to keep the solar panel perpendicular to the sun's rays.

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.

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.

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.

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.

Greenwich) however is my preference since the satellites go around this way and it
makes sense for the numbers to keep increasing if the satellite moves forwards.
Trying to do orbit calculations is bad enough without having numbers that keep
switching forwards and backwards.
Many satellite operators also use the 0 to +360 deg method, but may additionally
provide the “deg West” notation for some output publications.
Imaginary lines, also called meridians, running vertically around the globe. Unlike
latitude lines are not parallel. Meridians meet at the poles and are widest apart at the
equator. Zero degrees longitude (0°) is called prime meridian. The degrees of
longitude run 180° East and 180° West from the prime meridian in figure 1(a). In this
paper, microcontroller is used to drive the DC motor of the satellite dish in terms of
direction (East and West).
Microcontroller is used extensively where the precise position of the motor
driving the system is required. Microcontroller is as important as computer control
system. Remote control is used to command the signals to the microcontroller by the
user to drive the DC motor of the satellite positioning dish. The main benefit of the
microcontroller is also to control the position feedback. Microcontroller can be
command to move exactly to a specific position. Satellite dish requires the accuracy.
In this paper, PIC 16F877A microcontroller has been selected to control satellite dish
for the system. The advantages of PIC 16F877A microcontroller are low cost high
performance RISC ( Reduce Instruction Set Computer) have many I/O ports, timer,
memory and communication ports. So it is suitable for controlling actual position of
the systems. The system can locate the satellite receiver dish at five different
positions.
The most common issue anyone will come across when aligning the dish is
aiming at the correct satellite for the broadcasts they require. Satellite receivers do
have certain details on them regarding the satellites, but they cannot determine
whether you are aligned to the correct satellite. They rely on the user to align the dish
in the correct direction. There are certain details we will require in order to
successfully align the satellite dish accurately to the correct satellite for our
requirements, these are listed below and as shown in figure 1(b).
Azimuth: This will be the heading required for the dish. The satellite that is
broadcasting the signal will have a point of reference which the dish needs to be
aligned to (for example, Astra 2A, B or D is set at 28.2° East of True South).
Elevation: This is the angle of the dish elevation required that is above the reference
heading for the satellite that we have aligned the heading towards. As the Earth
curves, we need to find the correct elevation for the area where the dish will be
situated.
LNB Skew or Inclination: This is angle of the LNB on its axis. Much the same as
the elevation, we are required to find the correct skew or inclination for the area
where the dish will be situated.

of hardware components which remote controller, PIC microcontroller, relay driver
and DC motor based servo mechanism. A user will enter in a command such as
position of the satellite dish; a position will be generated, and then the control
software will be called. The software of the controller will determine a desired
position of the dish and send the command to the motor through the microcontroller.
Remote control sends the command 12 bits of information.

BLOCKDIAGRAM OF THE SYSTEM
Firstly, the motor is reaching in something degree when the power supply on. This
degree is called the last degree. If the setting switch is pressed to save degree and
count of the motor of the satellite dish, motor will go to the lowest limit from current
degree. After reaching to the lowest limit, the motor will stop. We get zero degree and
zero count. Then the motor will go to the highest limit. After reaching the highest
limit, the motor will stop. And then, the maximum degree is saved in the
microcontroller. So the maximum degree and maximum count are got.
Microcontroller calculated resolution and saved the degrees and pulses in EEPROM.
When command degree from remote control fed to the PIC microcontroller, the motor
is driven. The motor is driving with the counts. These counts are being sensed by reed
sensor. Reed sensor feedback counts of driving motor to the microcontroller.
Microcontroller makes increasing the counts if the command degree is greater than
the last degree. While increasing the counts, the motor will be stopped by
microcontroller when the command degree is equal to the last degree. Similarity,
microcontroller makes decreasing the counts if the command degree is less than the
last degree. While decreasing the counts, the motor will be stopped by microcontroller
when the command degree is equal to the last degree.

A.Infrared Remote Control Device
The infrared remote controller was composed of infrared remote control transmitter
and infrared remote control receiver. Structure of remote transmitter circuit was made
up of specific integrated circuit IC1 as the core element; matrix circuits for transmitter
keyboard were composed of matrix switches, which could constituted input circuit of
keyboard commands with pulse generator in the IC1 and signal encoder in the
keyboard. Remote receiver was composed by specific integrated circuit IC2 installed
with photodiode. When infrared light from remote control was received by
photosensitive tube of receiver, the light signal will be transformed as the electrical
signal by photosensitive tube.

B. Description of Signals of The IR Transmitter And Receiver
IR sensor module receives the IR pulses sent form remote and converts it to
corresponding electric pulses. These electric pulses are given to microcontroller that
decodes it to corresponding data byte using zero crossing detector and on chip timer
and interrupt. These data bytes are used to take further control decisions. The control
output signals are given to driver circuit, which drives the DC motor of the satellite
dish.
A Sony remote control transmitter is used in this paper. The Sony remote control
is based on the Pulse-Width signal coding scheme. The code exists of 12 bits sent on a
40 kHz carrier wave. The code starts with a header of 2.4milli second (ms) or 4 times
T, where T is 600 micro second (μs). The header is followed by 7 command bits and 5
address bits as shown in Figure.4. The address and commands exists of logical ones
and zeros. A logical one is formed by a space of 600 μs or 1 T and a pulse of 1200 μs
or 2T. A logical zero is formed by a space of 600 μs and pulse of 600 μs. The space
between 2 transmitted codes when a button is being pressed is 40 ms. The bits are
transmitted least significant bits first. The total length of a bit-stream is always 45 ms.
C. PIC Microcontroller
There are many different varieties of PICs. Some are OTP (One Time Programmable)
type devices and some are Flash type devices. OTP devices are not well suited for
electronics hobbyists because their software code cannot be changed when have been
programmed. Flash type devices are repeatedly reprogrammed in-circuit. There are
generally three types of Flash type device microcontroller .They are PIC 16F84A, 18
pin microcontroller, PIC 16F628A, 18 pin microcontroller and PIC 16F877A, 40 pin
microcontroller. PIC 16F877A microcontroller has built-in ADC (analog to digital
converter), USART (universal synchronous and asynchronous receiver transmitter),
PWM (pulse width modulation), more I/O ports and more program memory space.
Because of its capability, it has been chosen in this paper.
D. DC Motor Based Servomechanism
Nowadays, the most popular motor is a servo motor that is used to control and drive
for heavy load application. On the other hand, the servo motor cost is extensively high
for this application. So, YURI 518R servomechanism is choosen for this system. The
general view of the YURI 518R servomechanism is shown in Figure.5. It is supported
to drive over 250 kg loads, when only driven by 36V DC motor. In figure 3(b), the
mechanism consists of upper and lower limit switch. This limit switch are protected
not to damage the mechanism for extremely drive and internal magnetic on the main
axis and the feedback reed switch. The reed switch feedback 7 pulses per rotation and
totally 873 pulses for the whole movement of the inner rod.

MAGNETIC REED SWITCH SENSOR
A reed sensor is a device that built using a reed switch with additional functionality
like ability to withstand higher shock, easier mounting, additional intelligent circuitry,
etc. When a magnetic force is generated parallel to the reed switch, the reeds become
flux carriers in the magnetic poles, which attack each other. If the magnetic force
between the poles is strong enough to overcome the restoring force of the reeds, the
reeds will be drawn together. The reeds switch is in a sealed glass capsule usually
with a special insert gas that prevents the switch contacts from oxidizing (rusting).
When a magnet is brought within a specific distance, the reed blades become opposite
magnetic poles which attract. This closes the circuit and allows current to flow. When
the magnet is taken away, the reed blades lose their induced magnetic and separate
thereby opening the circuit. Because the switch is sealed it can be used in harsh
environments. Reed switches respond to both magnetic poles( North and South).

SOFTWARE IMPLEMENTATION OF THE SYSTEM
This system used remote control for input device and LCD module for output device
for user interfacing. Moreover other two different LEDs are used to indicate for motor
direction movement. The DC motor is driven by two electromagnetic relays with the
amplification of transistors. The position feedback is acquired by the usage of reed
switch interface with the help of the Opto-coupler.

A. Operation of the Motor
Microcontroller is used to drive the motor to the clockwise direction when the
command degree is greater than the last degree and counterclockwise direction when
the command degree is less than the last degrees in Figure.7. And it is used to drive
the motor with the desired degree by calculating the command degree from remote
and feedback degree from the reed sensor.
Microcontroller is used to drive the motor to the clockwise direction when the
command degree is greater than the last degree and counterclockwise direction when
the command degree is less than the last degrees in figure 4(A). And it is used to drive
the motor with the desired degree by calculating the command degree from remote
and feedback degree from the reed sensor.
B. Flowchart of the System
The overview of Satellite Dish Positioning System is shown in Figure8. After ports
and registers initialization the program will check whether the setting switch is
pressed or not. This means that if the setting switch press, the program will enter into
the set mode and displays the set menu. On the other hand if not pressed the setting
switch, the program will enter into the search mode to get the desired degree. The
setting mode is used to save the degrees and counts of the motor. So, the user can
choose one of the two modes set mode and search mode. The actual position of the
satellite dish is saved to the EEPROM to reduce system errors while power supply
failure is taken.

5. CONCLUSION
This paper is intended to drive the satellite dish to the select channel’s position. At
first the system displays the satellite dish positioning menu and waits for the user
input desired channel via remote control. When the desired channel is selected, the
program first calculated which direction is needed to drive. And the load current from
EEPROM displays on the LCD. The dish is driven by the searching subroutine and
feed backed and calculated by check feedback signal subroutine. The direction
movement of the dish is indicated by two LED. If the forward direction is taken the
green LED will indicate and for opposite direction the red LED will indicate. As soon
as, the driven position is reached the program will stop the motor and two LEDs will
off. In this paper, reed sensor is used to send the feedback signal to the
microcontroller that the satellite dish is in the desired position or not. If the sensor is
not connected, the system will hang and the user must reset the system. And
microcontroller cannot connect a motor directly because it cannot give sufficient
current to drive the motor. So, in this system, motor driver circuit is designed with
two relays as switches which it is used to drive the motor with clockwise and
counterclockwise direction. Satellite dish positioning system can be provided with
computer system without microcontroller. But microcontroller is a single chip it is
low cost, small size and high performance. So, microcontroller is most suitable for
auto positioning system. In this system, a satellite positioning system has been
developed. A satellite dish control system is critical to its tracking capability.
Satellites are controlled by a ground station antenna on earth that sends commands
and receives information from the satellites. This system is used remote control to
start the motor moving in the desired direction. PIC microcontrollers are widely used
all over the world and it is based on the latest technologies. Using the remote control
improves the advanced technology. And using the microcontroller develops the motor
to maintain the desired position. Although this is the firstapproaching step to the
control system, automation system and robotics systems, these can greatly serve to the
industrial control.
