Automatic vision based inspection of railway trackeSAT Journals
Abstract Currently, most of railway track inspections are manually conducted by railroad track inspectors. Practically, it is not possible to inspect the thousand of miles of railway track by trained human inspector. This inspection takes too much time to inspect the defected railway track and then inform to the railway authority people. In this way it may lead to disaster. Hence to avoid delay and improve the accuracy, our propose system will automatically inspect the railway track by using vision based method and vibration based method. This method proposes continuous monitoring and assessment of the condition of the rail tracks which prevent major disasters. Our proposed system will inspect the rail track component such as missing bolts, tie plates, anchors etc by using vision based method and simultaneously do the calibration of railway track by using vibration based method. The system provides real-time monitoring and structural condition for railway track using vision based method and calibration to search the fault location on the track. Inspections include detecting defects on tracks, missing bolts, anchor, tie plate and clips etc. In vision based method camera we will use to capture the images or videos. In vibration based method some sensors we will use to detect the vibrations on the railway track. We will extract the signal from 2-D. Keywords: Railway track inspection, Vision based and vibration based method, Image processing, Data acquisition.
Hybrid and Electric Drives are far more complex than the traditional I.C. Engine based powertrains of cars and trucks. Such complexity multiplies the possible failure modes that could lead to catastrophic failure of the drivetrain, as well as make the job of optimizing the powertrain for fuel efficiency, much more challenging. Model Based Design is a solution to manage complexity, find and eliminate failure modes, and to find and exploit even obscure performance improvement opportunities.

Towards Rapid Implementation of Adaptive Robotic SystemsMeshDynamics
Current automation design practice produces expensive one-of-a-kind installations where the system cannot be easily modified to
meet changing demands or advancements in technology. It is imperative that we design robot systems to be modular, portable and
easily re-configurable in order to reduce the design lead times and life cycle costs of providing automation alternatives.
The Unified Tele-robotics Architecture Program (UTAP) was developed under the sponsorship of the US Air Force Robotics and
Automation Center of Excellence. A goal of the program was to define and develop prototypes of commonly used software building
blocks for sensor guided real time embedded control of telerobotic devices. Standard building blocks and a non-proprietary
communication protocols would provide the Air Force and specifically the Logistic Centers with a support infrastructure designed to
rapidly and efficiently build and maintain mission critical automation systems.
Image processing based girth monitoring and recording system for rubber plant...sipij
Measuring the girth and continuous monitoring of the increase in girth is one of the most important processes in rubber plantations since identification of girth deficiencies would enable planters to take corrective actions to ensure a good yield from the plantation.
This research paper presents an image processing based girth measurement & recording system that can replace existing manual process in an efficient and economical manner.
The system uses a digital image of the tree which uses the current number drawn on the tree to identify the tree number & its width. The image is threshold first & then filtered out using several filtering criterion to identify possible candidates for numbers. Identified blobs are then fed to the Tesseract OCR for number recognition. Threshold image is then filtered again with different criterion to segment out the black strip drawn on the tree which is then used to calculate the width of the tree using calibration parameters. Once the tree number is identified & width is calculated the girth the measured girth of the tree is stored in the data base under the identified tree number.
The results obtained from the system indicated significant improvement in efficiency & economy for main plantations. As future developments we are proposing a standard commercial system for girth measurement using standardized 2D Bar Codes as tree identifiers

Online aptitude test management system project report.pdfKamal Acharya
The purpose of on-line aptitude test system is to take online test in an efficient manner and no time wasting for checking the paper. The main objective of on-line aptitude test system is to efficiently evaluate the candidate thoroughly through a fully automated system that not only saves lot of time but also gives fast results. For students they give papers according to their convenience and time and there is no need of using extra thing like paper, pen etc. This can be used in educational institutions as well as in corporate world. Can be used anywhere any time as it is a web based application (user Location doesn’t matter). No restriction that examiner has to be present when the candidate takes the test.
Every time when lecturers/professors need to conduct examinations they have to sit down think about the questions and then create a whole new set of questions for each and every exam. In some cases the professor may want to give an open book online exam that is the student can take the exam any time anywhere, but the student might have to answer the questions in a limited time period. The professor may want to change the sequence of questions for every student. The problem that a student has is whenever a date for the exam is declared the student has to take it and there is no way he can take it at some other time. This project will create an interface for the examiner to create and store questions in a repository. It will also create an interface for the student to take examinations at his convenience and the questions and/or exams may be timed. Thereby creating an application which can be used by examiners and examinee’s simultaneously.
Examination System is very useful for Teachers/Professors. As in the teaching profession, you are responsible for writing question papers. In the conventional method, you write the question paper on paper, keep question papers separate from answers and all this information you have to keep in a locker to avoid unauthorized access. Using the Examination System you can create a question paper and everything will be written to a single exam file in encrypted format. You can set the General and Administrator password to avoid unauthorized access to your question paper. Every time you start the examination, the program shuffles all the questions and selects them randomly from the database, which reduces the chances of memorizing the questions.
NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.

The Research And Development Of Measurement Robot
Automatic Monitoring Systems
Luo Kaitian
Department of Computer Science Sichuan University for Nationalities Kangding, China
I. THE BASIC COMPONENTS AND MEASURING PRINCIPLES OF THE
MEASUREMENT ROBOT
The measurement robot, also known as the total station, is a comprehensive surveying system, which
includes the basic functions of auto target recognition (ATR), autocollimation, auto target tracking (ATT), auto
angle and distance measurement and automatic recording. It minimizes labor intensity, greatly improves work
efficiency and achieves a more accurate result. The major subsystem of the measurement robot contains eight
parts, namely a coordinate system, manipulator, transducer, calculator & controller, closed-circuit control
sensor, decision maker, target acquisition and integrated sensor. First of all, by using a spherical coordinates
system, the coordinate system can find targets in the range of 360° horizontally and 180° vertically; the
manipulator is mainly used to adjust rotation; the transducer transforms electrical energy into mechanical energy
that activates the stepper motor; the calculator & controller boots up and shuts down the operating system(OS)
and stores data while creating conditions for other systems related to dock; the closed-circuit control sensor
transmits collected data to the manipulator and controller in order to fix positions accurately and measure; the
decision making is used to find targets; target acquisition, including setting thresholds, region-segmentation
method and heliography, is mainly for precisely collimating targets and the integrated sensor is used to collect
data.The basic measuring principles are: processing images collected by the image sensor to achieve automatic
tracking and precise collimation under the control of the calculator & controller. In general, surveyors plan a
measuring strategy based on information acquired from a measuring task. They obtain data using sensory
recognition analyzing the surroundings and targets via the available instruments. While measuring the robot can
identify, judge, analyze, automatically control, collimate and indicate. It can be connected to a computer and or
softwares for data analysis and program design and has high automation, remote control, fast response and high
precision features. The measurement robot has passed three stages of development. Currently, it can use image-
processing to automatically recognize, match and autocollimate targets according to their counters and textures,
and can realize 3D imaging.
II. THE PRINCIPLES OF MEASURING ROBOT’S DEVELOPMENT AND THE
REALIZATION OF AUTOMATIC MONITORING SYSTEMS PREPARE YOUR PAPER
BEFORE STYLING
The principles
Internationally famous measurement solution providers have launched their own products. The robot
produced by Leica Geosystems in Switzerland has always been leader in the development of this industry
because of its high precision, stability and ease of secondary development. The high-performance Leica
TCRA1201 intelligent measuring robot with its high precision is widely employed for construction use. This
paper studies the way its hardware device and Microsoft Visual C#2008 as the programming language are used
to develop software. The secondary development can be carried out with a uniform serial interface GeoCOM
instruction set. GeoCOM, a COM component in the form of DLL (Dynamic Link Library), specially developed
by Leica Geosystems for secondary development, can provide users with a more personalized UI (User
Interface) or allow users to develop more advanced client applications on the basis of the Leica measuring
devices. It has two interface modes: the advanced function mode and ASCII. The former uses VB (Visual
Basic) or C++ and can directly invoke the request, response and analytic function packaged in the COM
component; the latter, constructed to demand, uses serial line to send request to the robot and immediately
receiving response decoding. During each process of the latter there is a corresponding specific identification
code related to given parameters. Although the advanced function mode is highly integrated and easy to invoke,
ABSTRACT:
This paper describes the hardware components and principles of measuring of the
measurement robot and introduces its secondary developmental principles. For the purposes of this
study serial control between the computer and the measuring robot was studied. Through the analysis
and coordination of software requirements, engineering automation observations, Microsoft Visual
C#2008 programming language, and Leica Geosystems GeoCOM robot programming interface,
developers can achieve the engineering standards of automatic monitoring data acquisition software.
Experiments show a high degree of automation software improves work efficiency in significant ways.

The Realization of Automatic Monitoring
Because the location and numbers of the observation spot are relatively fixed, in order to realize
unattended, real-time, consecutive, effective and dynamic automatic measurement, the software used can
automatically search, collimate and indicate in a certain field range to finish tasks like timing measurement,
calculation, analysis and output. The objective Automation. The automatic monitoring software strictly
implements auto detection and processes and analyzes data feedback according to given observation set
numbers and observation intervals. Intelligence. When blocked and not meeting tolerance requirements, the
software should command the robot to measure again, and if necessary, give an alarm. Mass storage. After
measuring there is a large amount of data. The DLL can store and manage data effectively and provides data
query and analysis. Friendly and easy user interface. For the convenience of users, the software should have an
easy-to-use interface and simple operation. The main functional modules of the automatic monitoring software
This software mainly consists of project management, system preferences, survey station settings, measurement
learning, automatic measurement, data processing and output. Project management. Each engineering project
has a corresponding database file that stores data including system preferences, original values and a range of
calculated analysis.
System preferences. Set the computer’s serial communication parameters to conform to the robot’s baud
rate, calibration stop bit, 2c mutual error, index error. Misclosure of the round will be set as well.
Survey station settings. These include settings of the name of the station, the height of the instrument
and prism constants.
Measurement learning. Firstly, users supply rough information about the target spot. After auto search,
precise collimating and surveying, location data is recorded.
Automatic measurement. The software will, if running over time, automatically remeasure part or all of
the target according to the numbers configured.
Data processing. Based on the original data, the software will calculate and analyze.
Output. It provides enquiry and output of the original observation data, calculation and analytic results
and generate forms and charts.
Friendly and easy user interface. For the convenience of users, the software should have an easy-to-use
interface and simple operation.

2) Measurement learning and storage of the Datum point BM1~BM4 and the observation spot J1~J2.
3) Collect data 3 times of observation set according to the parameters in Table 3. If the results do not meet the
requirements in Table 3, the tester is warned and the robot will remeasure part of target or the whole.
4) After auto measurement, make coordinate calculations and store the results. The observation spot’s eight-
period coordinate transformation is presented in Figure 4and Figure 5. And this system based on measurement
robot is proved to be capable of the surveying requirements and increasing work efficiency.
