Real-time eye and iris tracking is important for handsoff gaze-based password entry, instrument control by paraplegic patients, Internet user studies, as well as homeland security applications. In this project, a smart camera, LabVIEW and vision software tools are utilized to generate eye detection and tracking algorithms. The algorithms are uploaded to the smart camera for on-board image processing. Eye detection refers to finding eye features in a single frame. Eye tracking is achieved by detecting the same eye features across multiple image frames and correlating them to a particular eye. The algorithms are tested for eye detection and tracking under different conditions including different angles of the face, head motion speed, and eye occlusions to determine their usability for the proposed applications. This paper presents the implemented algorithms and performance results of these algorithms on the smart camera.

The perception of this paper based on a project done for adjusting and monitoring of fuel supply in power plant boilers using LabVIEW. For power generation, in thermal power plant system water is converted to steam and the steam is send it to the high pressure turbine in order to rotate the shaft then the power has been produced. The Natural Gas (Methane, CH 4 ) is used as more reliable fuel for boilingthe water. The fuel supply is controlled by using Programmable Logical Controller (PLC) mechanism. The proposed method has implemented using LabVIEW for monitoring and controlling the fuel supply for increasing the fuel efficiency and safety. Fuel Supply System (FSS) has modeled in LabVIEW for easy access of the system. The communication between the LabVIEW and PLC is done by using Object Linking and Embedding for Process Control (OPC) server software. This proposed method the natural gas is controlled and energize, two boilers and one pilot's gun is used for ignition.

Pressure is an important physical parameter to be controlled in process boiler, heat exchanger, nuclear reactor and steam carrying pipeline. In the article the issue has been face in boiler operation due to pressure is handled. In boiler, the problem is due to maximum and minimum range of pressure. Due to the issues there is a chance to causes the hazop. To avoid such the problem the high and low pressure in boiler has to control. In the paper such the problem has sorted out by implementing ON-OFF control. Here the proposed control action for pressure control is implemented with the help of LabVIEW (Laboratory Virtual Instrument Engineering Workbench) software and NI ELVIS hardware. In the idea the boiler’s low range and high is monitored and controlled valve desirably. And also the high range and low range of pressure in the boiler is signified to plant operator by alarm signal.

Blood Pressure is the pressure exerted by blood on the
walls of arteries. Normal blood pressure is considered to be a
systolic blood pressure of 120 millimetres of mercury and
diastolic pressure of 80 millimetres of mercury (stated as "120
over 80"). If an individual were to have a consistent blood
pressure reading of 140 over 90, he would be evaluated for
having high blood pressure. If left untreated, high blood pressure
can damage important organs, such as the brain and kidneys, as
well as lead to a stroke. Thus it becomes important to measure
blood pressure as it can lead to early diagnosis of diseases that
may be linked to high or low blood pressure. PTT is the time
taken by the arterial pulse propagating from the heart to a
peripheral site. This can be calculated from ECG signals and
PlethysmoGram signals. Since, PTT has been found to be
correlated to Blood Pressure, it is imperative to calculate PTT
accurately. In this paper, a relation has been developed between
PTT and Blood Pressure using regresssion analysis. Another
indicator, known as the Photoplethysmogram Intensity Ratio,
henceforth known as the PIR has also been used in estimation of
the Blood Pressure. The coding has been done in LabVIEW
which is has a graphical programming syntax that makes it
simple to visualize, create, and code engineering systems.

Computer based instrumentation systems has promoted greatly the development of test and measurement technology. In last years two key technologies are proposed in this realm-Virtual Instruments and LAN eXtensions for Instrumentation (LXI). Virtual instrument uses computer software to add additional functionality or replace some hardware. On the other hand LXI constructs hybrid and distributed network measurement systems via Ethernet bus. The objective of this paper is to discuss the design, development and implementation of LXI instruments using LabVIEW Plug and Play instrument drivers. With proper measurement hardware these virtual instruments can be used for local and remote measurements, analysis, design and distributed control.

In view of reducing constraint parameters of any communication system several techniques were implemented using algorithmic approach only. Usually good architectural
design and advanced technology process reduces time delay significantly. Network security an emerging outlook in communication system plays an important role for reliable communication in everyday life. Therefore in this novel work the Advanced Encryption Standard as a promising trend in network security is discussed. The unique feature of this proposed work is on fly key instead of pre-computation key algorithm. The pre-computation algorithm consumed more time during different iteration of encryption. The on fly key generation reduces the delay associated with each round of
encryption results in reduction of overall encryption delay. This will leads to increase the throughput in message encryption using architectural design level. This work uses NI-LabVIEW as an implementation platform for simulation. In presented work AES 128/192/256 is implemented using on fly key generation module at architectural design.

The result of simulator and discussed mathematical modeling was very accurate. The maximum error is little than 1%. So, it is acceptable to use in various studies and researches of photovoltaic energy.

Diabetes carries with it neurovascular entanglements, which winds up being developed of increment in pressure among the foot districts. Typically diabetic patients with poly neuropathy regularly lose agony and temperature sensations in their feet, bringing about insuf icient weight under their feet, during strolling or standing. This may cause injury in the feet; easy injury creates and brings about ulceration. So counteraction of diabetic foot ulcer is required. A circuit is proposed to quantify the weight on the foot with the assistance of power detecting resistor. The weight on the foot is gained by the sensor. For huge scope information procurement framework, a graphical program condition like LabVIEW is required. As indicated by the Normalized Peak Pressure (KPa) values arrangement of ordinary and diabetic neuropathy patients was finished. In this strategy analysis of foot ulceration is done in a prior stage consequently the further ulceration is forestalled.

The design, analysis and implementation of a robot arm system, which is expressed towards its performance with an analytical model by using LabVIEW and embedded system tools was presented in this article. Mathematical modeling of kinematics plays an essential role in design and implementation of a robot arm control. The projected work was focused to control the end effector of the robot arm to achieve any accessible point in an amorphous region using LabVIEW, ARM (Advanced RISC (Reduced Instruction Set Computing) Machine) microcontroller and Dexter ER2 robotic arm. LabVIEW uses analytical method to design the inverse kinematic model of the robot arm. The inverse kinematic model and robot arm control was implemented using LabVIEW and ARM microcontroller. LabVIEW uses the parallel communication to send the joint angles of the robot arm to the ARM. ARM microcontroller uses five PWM (Pulse Width Modulation) signals in order to control the robot arm, which was geared up with servo motors. Robot arm was controlled manually through the LabVIEW GUI (Graphical User Interface) controls. The present paper discussed about the mechanical configuration, analytical modeling, software and hardware of the above said work.

This paper presents a digital proportional-integral controller implementation for a Coupled Tanks System for liquid level control. The model identification is done by sinusoidal signal at different frequencies, as result the bode plot obtained is applied for designing the controller. One of the main advantages of programming the digital controller in Labview is the possibility of sending small gains which allow to get a better performance for fixing the parameters: settling time and overshoot. Since the system is nonlinear the mathematical model is also presented to compare with the experimental model obtained. The obtained results on simulation are shown as well as the implementation of two PI controllers one in the control module that has the tanks system used (CE105MV) and another in Labview.

This thesis is concerned with modeling of structural dynamics, dynamic stiffness, and active control of unwanted vibrations in Parallel Kinematic Mechanisms (PKMs) as a result of flexibility of the PKM linkages.
Using energy-based approaches, the structural dynamics of the PKMs with flexible links is derived. Subsequently, a new set of admissible shape functions is proposed for the
flexible links that incorporate the dynamic effects of the adjacent structural components. The resulting mode frequencies obtained from the proposed shape functions are
compared with the resonance frequencies of the entire PKM obtained via Finite Element (FE) analysis for a set of moving platform/payload masses. Next, an FE-based
methodology is presented for the estimation of the configuration-dependent dynamic stiffness of the redundant 6-dof PKMs utilized as 5-axis CNC machine tools at the Tool
Center Point (TCP). The proposed FE model is validated via experimental modal tests conducted on two PKM-based meso-Milling Machine Tool (mMT) prototypes built in the
CIMLab.
For active vibration control of the PKM linkages, a set of PZT transducers are designed, and bonded to the flexible linkage of the PKM to form a “smart link”. An electromechanical model is developed that takes into account the effects of the added
mass and stiffness of the PZT transducers to those of the PKM links. The electromechanical model is subsequently utilized in a controllability analysis where it is shown that the desired controllability of PKMs can be simply achieved by adjusting the
mass of the moving platform. Finally, a new vibration controller based on a modified Integral Resonant Control (IRC) scheme is designed and synthesized with the “smart link” model. Knowing that the structural dynamics of the PKM link undergoes configuration dependent variations within the workspace, the controller must be robust with respect to the plant uncertainties. To this end, the modified IRC approach is shown via a Quantitative Feedback Theory (QFT) methodology to have improved robustness against
plant variations while maintaining its vibration attenuation capability. Using LabVIEW Real-Time module, the active vibration control system is experimentally implemented on
the smart link of the PKM to verify the proposed vibration control methodology.
