The magnetic liquid known as ferrofluid is a liquid, acts as a smart material, which becomes strongly magnetized in the presence of a magnetic field. The aim of this work to develop standard, economical method for synthesis of iron oxide nanoparticles along with their coating with oleic acid resulting in good quality of stable ferrofluid. The authors have prepared ferrofluid where nanoparticles are suspended in kerosene. To avoid aggregation, nanoparticles are coated with oleic acid. In present work, the stability of ferrofluid is considered in terms of particle size, size distribution and magnetization. The properties of final fluid are studied with the help of various analytical techniques; X-ray diffraction (XRD), Transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FTIR) which are used for the determination of characteristics of ferrofluid like interatomic distance, size and shape of the particles and adhesion of oleic acid to nanoparticles. In account of synthesized ferrofluid, remaining part of work is dedicated to application of ferrofluid in the inclination sensor. In present there are many commercial applications of ferrofluids such as cancer detection (MRI test), speakers etc. Here the focus is given to construct ferrofluid based inductive inclination sensor as one of the application of the ferrofluid. The range of inclination sensor developed by us is ±12° and the resolution is ~ ±0.5°.

The modern metal machining industry has overcome their limitations of working in order to machine all the points of the work piece. 5 axis machine tools have demonstrated the capability to perform intricate machining operations. Various machining operations involving undercut areas, deep cavities, sharp corners are demonstrated successfully using 5 axis machine tools. However, to perform these operations, often special fixtures, special tooling, tools with longer out sticks, and expensive electrodes are needed. These auxiliary tools are needed to achieve high quality with shorter manufacturing time. This further also leads to substantial saving of the manufacturing cost. Recent developments in CAD/CAM also have made greater impact on the efficient utilization of the 5 axis machine tools. Special attention is given to cutting tools and tool holding systems that support the whole process. This paper focuses on the review of the techniques applied to utilize 5 axis machine tools to improve the quality of the product with lesser machining time.

The detection and monitoring of gases in exhaled human breath till date has been limited by the lack of appropriate materials and technologies which could rapidly and selectively identify the presence and monitor the concentration of trace levels of specific biomarkers. In this paper, a method for detection of NO in exhaled breath has been proposed. Development of a continuous wave, thermoelectrically cooled, Distributed Feedback Quantum Cascade Laser (DFB-QCL) based sensor platform operating near 5.26 μm, in combination with QEPAS has been proposed for the quantitative detection of exhaled NO concentrations, which is a biomarker of airway inflammation and can indicate the extent of respiratory diseases.

Multimedia sharing has become a recent trend over the Internet among which videos are an integral part. In order to handle such large amount of video data, classification techniques are necessary. This paper provides a video classification technique which uses a Fuzzy rule base to calculate a fuzzy measure `Edginess' for each pixel. Differences in pixel intensity are calculated and compared with a fuzzy rule base to calculate edginess. This edginess measure is used to decide whether a pixel belongs to an edge or not. Features extracted from training videos train the Naive Bayesian Classifier which is then used for testing videos. Features are pre-processed using techniques such as Discretize, Fuzzy Logic, Numeric to Binary, PKI Discretize and Normalize. Then, they are filtered using Correlation Feature Selection before training the classifier. Experimental Results show that a high accuracy of classification can be achieved with Fuzzy edge detection technique.

The system “Temporal analysis and remote monitoring of ECG signal” is developed to assist patients and doctors in health care. An arrhythmia is an abnormal heart rhythm. It can cause the heart rate to be too slow or too fast. Enough blood is not provided by the heart to the body when arrhythmias are severe or last long enough. This can cause patient to feel tired, lightheaded or may make him pass out. It can also cause death. Before treatment, it's important for the doctor to know where an arrhythmia starts in the heart and whether it's abnormal. An electrocardiogram (ECG) is often used to diagnose arrhythmias. “Temporal analysis and remote monitoring of ECG signal” is meant to acquire ECG signal from patient and analyze it to detect and classify its anomalies and abnormalities. This is achieved by extracting amplitudes and durations of parameters of ECG waveform such as P wave, QRS complex, RR interval and PR durations. These parameters are compared with the normal values to determine the type of abnormality. Database of the patient is maintained for further use by the doctor. Under critical conditions, transmission scheme will ensure successful transmission of critical messages to doctors via Global system for mobile (GSM) network.

Multilevel inverters had gain popularity over the years in industrial applications such as motor drives, static var compensators and renewable energy systems. Multilevel inverters have received this attention as it promises fewer disturbances and are capable to function at low switching frequency as compared to two level inverters. Out of many multilevel inverter topologies proposed, Cascaded Multilevel Inverter (CMI) features a high modularity degree because each inverter can be seen as a module with similar circuit topology, control structure and modulation. With large number of advantages, cascaded multilevel inverter has one major limitation of voltage unbalance across the dc capacitors. This paper explores basic structure and operating principle of cascaded multilevel inverter. Common modulation techniques are summarized. This paper also presents Phase Disposition (PD) and Phase Opposition Disposition (POD) SPWM techniques along with module voltage balancing algorithm such as sorting strategy for a cascaded multilevel inverter. The THD of PD and POD SPWM techniques are compared. For PD-SPWM technique, it is observed that the output voltage of inverter contains even harmonic components because of half wave unsymmetry in phase switching function.

The rolling element bearing is an important element used in rotating machinery. The performance of any mechanical system depends on condition of the bearing. Hence, to avoid failures condition monitoring of rolling element bearings is essential. In the present study, effect of surface failure on inner and outer race of bearing on vibration spectrum is proposed. The vibration spectrum is acquired for healthy bearing and bearing with surface failure failures on outer and inner race of bearing. The experimental study is carried out with various defect sizes on inner and outer race of bearing surface, at various shaft excitation frequencies. Vibration spectrums are acquired using a tri-axial shear type accelerometer (Type AC 102-A, SI.NO.66760) along with the photon+ (Bruel and Kajer) ultraportable dynamic signal analyser. The experimental results are compared with ball pass frequency of inner and outer race. It has been found that the percentage of errors is within permissible limit. Key words - Rolling element bearing, Bearing defect, Bearing characteristics frequencies, condition monitoring.

Formula Student Racing competitions are international events organized by Society of Automotive Engineers globally at various Formula SAE Circuits. Teams comprising of college students worldwide thrive to build a Formula style race car to compete at these events. In this high octane racing event every team tries to have an inch over their opponents by reducing lap timings. The best way for minimal lap timings is better performance along the straights and a good cornering. It becomes difficult for cars to get good traction when traveling at high speeds as well as they need to reduce their speeds drastically to take sharp corners. To maximize the performance of team NITK Racing car for such events an aerodynamic wings package at the front and the rear is proposed which produces sufficient down-force when accelerating in the straights as well as allowing sharp corners at relatively higher speeds. Being a student based competition intense amount of care is given to the safety precautions. Cars having sharp corners and protrusions are liable to be disqualified and hence the wing tip needs to be modified in order to satisfy the safety rules of the competition.
