This paper presents a new method of threshold estimation for ECG signal denoising using wavelet decomposition. In this method, threshold is computed using the maximum and minimum wavelet coefficients at each level. Using this threshold and well known Hard thresholding process, the significant wavelet coefficients from each level are selected and denoised ECG signal is reconstructed with inverse wavelet transform. The performance of this method is compared with all well know wavelet shrinkage denoising methods with bior4.4 wavelet using root mean square error (RMSE) and signal to noise ratio (SNR) on MIT-BIH ECG database. The proposed threshold estimation is simple and faster compared to all existing threshold calculation methods namely VisuShrink, SureShrink, BayesShrink, and level-dependent threshold estimation and gives better SNR and RMSE. Proposed threshold estimation process decreases data sorting and storing resources allowing low-cost and faster implementation for portable biomedical devices.

Radial pulse signal analysis is an extensively explored diagnostic tool in traditional Indian as well as Chinese school of medicine. Objective examination of radial pulse signal and effect on its temporal domain characteristics features, as a result of activities conducted on healthy individuals have been evaluated. Radial pulse analysis, using pulse peak-peak variability-basis, on lines similar to heart rate variability, has been performed. Analysis of radial pulse signal for extracting respiration, thermoregulation and auditory perception related rhythms, prominently visible in HRV spectrum, has been attempted and results compare well with those reported from HRV analysis. Effects of posture change on pulse signal, have also been examined.

Broadband microstrip antenna is more commonly realized by cutting the slot at an appropriate position inside the patch which is fabricated on lower dielectric constant thicker substrate. In this paper, a new 2700 sectoral microstrip antenna is proposed. The 2700 sectoral patch, derived from conventional circular microstrip antenna, has an additional mode below the resonance frequency of fundamental mode of the equivalent circular patch. The variations of sectoral patch, namely, 3000, 3200 and 3400 sectoral microstrip antenna are also discussed. By studying the surface current distributions at first two modes of sectoral patch, a formulation in resonant length / patch radius, is proposed. The frequencies calculated using them closely agrees with the simulated results. Further a rectangular slot cut 2700 sectoral microstrip antenna is proposed. An analysis to study the effects of slot in sectoral patch is presented. The rectangular slot reduces the resonance frequency of second order mode of 2700 sectoral patch and along with its fundamental mode, yields broadband response. The measured and simulated BW of nearly 450 MHz at center frequency of around 1000 MHz is obtained. The proposed broadband antenna shows broadside radiation pattern with gain of more than 6 dBi over the operating bandwidth.

This paper presents a system to automatically analyse a basketball long-shot using trajectory-based ball tracking method from a basketball video sequence. The accuracy of a long-shot in a basketball game is mostly dependent on the ball throwing angle and the velocity at which the ball is to be thrown. The proposed system detects and tracks the ball in a basketball long-shot sequence by exploiting the trajectory information of the ball. The ball motion characteristics are used to determine the ball trajectory. The candidate trajectories are generated from a set of ball candidates in each frame. The trajectory-based ball tracking minimised the rate of error of ball tracking in the video which occurs due to occlusion and merging of the ball image with other objects in the frame, distortion of the ball image due to ball and camera motion and the presence of many moving objects in the foreground and background in the video. The ball locations verified by the tracking results are then used to estimate the ball throwing angle and the throwing velocity. The experiments show encouraging results for videos with dynamic background and different illumination conditions.

A novel, compact and dual polarized ring Sectoral Monopole Antenna (RSMA) with defected ground is presented for Ultra Wide Band (UWB) applications. Present structure has been derived from the circular monopole antenna to accomplish dual polarization characteristics without much change in the impedance band width, radiation pattern (quasi Omni-directional) and other antenna characteristics. Proposed RSMA with partial and defected ground design, UWB response (i.e. 3.1 GHz-10.6 GHz) with reference to VSWR<;2 is achieved. The antenna is fabricated on a RT/Duroid5880 (εr =2.2) substrate having thickness of 0.785 mm with total real-estate of 20×28 mm2. Measurements are in close agreement with the simulated results. Dual polarization characteristics ensure that proposed antenna can be a promising candidate for the UWB applications.

In this paper, a rotor-flux model reference adaptive system (MRAS) based speed sensorless direct torque and flux control (DTFC) of induction motor drive (IMD) using sliding-mode control (SMC) and fuzzy logic control (FLC) based adaptation mechanism schemes are implemented to replace the conventional constant gain PI-controller (PIC). The SMC is considered to minimize the error dynamics under different loading conditions, which is derived based on Lyapunov theorem. Furthermore, the FLC adaptation scheme is proposed to minimize the chattering phenomenon as well as achieve high performance speed sensorless drive with less error signal. The performance of each adaptation control schemes has been tested for its robustness to sudden change in speed and load disturbance. A detailed comparison of different control schemes are carried out in a MATALB/Simulink environment in both sensor and sensorless modes of operation, when a IMD is operating in forward and reversal motoring under no-load, load, sudden change in speed and sudden zero speed conditions.

Use of IPv6 protocol is increasing due to lack of address space in IPv4 protocol. Along with increased address space, IPv6 also provides simplified header and additional functionality is put in the form of extension headers which can cause certain network threats, if misused. Network devices and operating systems are not at the matured stage to handle threats against IPv6 protocol. Reason being, not all network devices and operating system are fully RFC complaint. Even if they are, experience with IPv6 protocol is less, so there are possibilities of many unknown threats. This research investigates the threats due to misusing IPv6 destination option and fragmentation extension headers. Attacks addressed are fragmentation attack where upper layer protocol not present in first fragment i.e. tiny fragmentation attack, overlapping fragmentation attack, and flooding attack due to unknown option in destination option header. To verify these attacks, real test network set up is used. For each attack, detection logic is proposed and implemented in Linux environment using advanced shell scripting and C programming. To create packets with attack vectors Scapy - Python based packet manipulation tool is used. The proposed solution can run in host in order to detect these attacks and raise the alarm.

A novel compact microstrip line fed diamond shaped monopole antenna for Ultra Wideband (UWB) applications is proposed. The antenna structure consists of a diamond shaped radiating patch and a semicircular like ground plane. The radiating patch is derived from a conventional rectangular patch antenna. The simulated results show that the impedance bandwidth (VSWR ≤ 2) of the proposed antenna ranges from 0.8409 to 15.5109 GHz (179.4%) and 16.7679 to 18.3753 GHz (9.15%).

Automatic image registration is still a major challenge in many of the image processing applications, to name a few-remote sensing, medical imaging, industrial image analysis etc. In general, the problem of image registration can be identified as the determination of translations and a small rotation between the respective source images and generation of the resulting registered images. The most critical issue in regards to appropriate image registration is the variability in terms of the different image sensors in producing the source image, which can affect the accuracy in the resultant registered image. In this paper, we have proposed a novel image registration technique based on wavelet theory and near-fuzzy set approach. We have used five sets of test images for our experiment and the experimental results for the entire test sets are superior in terms of noise reduction and varied difference in the image content compared to the other related research works. To the best of our knowledge, our approach of image registration using near-fuzzy set approach is first of its kind and the superior quality of the resultant registered image can well justify its novelty.
