The widespread use of airborne vehicles and its growing applications in various domains can be attributed to their ability to operate in inaccessible areas, thus decreasing the human loss in major accidents, and making access easy to dangerous conditions. These pilotless airborne vehicles with some remote sensing techniques involved in it, are emerging as a new technology. The airborne vehicles are enduring, cost effective and also provide a reliable platform for surveying. Consequently, small airborne vehicles, here Quad copter, equipped with sophisticated components can capture and transmit the image or video to the Data Base. They are sent for processing and made accessible to the Geographical Information System (GIS), where further analysis is done for the proceedings of the rescue operation. This application finds a great utility predominantly in industries and military.

In this paper, the design of a two port antenna for ultra wideband applications is presented. The radiating element in the antenna is an L-shaped slot which is excited using two microstrip feed lines for generating the orthogonal polarizations. The slot and the feed lines have stepped profiles for achieving wideband impedance matching. The decoupling between the ports is provided by means of three different structures. First, a slant metallic strip is attached at a corner inside the L-shape slot, next, a trident shaped slot is etched below the L-shape slot near its corner and finally, a kite shaped slot is placed in the center. The impedance bandwidth achieved with the antenna is from 3 GHz to 11.6 GHz while the isolation is better than 20 dB from 3.8 GHz onwards. The dual polarized nature of the antenna is shown from the aperture electric field distribution and the radiation patterns. The peak gain of the antenna varies from 4 to 6 dBi over the band. The antenna is expected to be useful for dual polarization applications in radar, imaging and high speed wireless communication.

Considering the advantages of multiple inputs multiple outputs (MIMO) over the single input single output system (SISO), authors have developed various techniques to implement the designs for various applications. In this review paper, a brief investigation has been done on the effort done in last decade. In wireless MIMO both the transmitting and the receiving end is equipped with multiple antenna elements. Various authors have exposed the philosophy behind MIMO system. In that they have elaborated that the transmitting antennas and receiving antennas are jointly combined in such a way that fading will decrease and the bit transfer rate will increase so at the receiving end we will get high signal to noise ratio (SNR). At the system level, careful design of MIMO signal processing and coding algorithms can lead to an increase in the capacity and coverage.

The paper investigates on recognition of breast abnormalities. A novel feature frame work was proposed on mammographic patches based on both texture and geometric features for classification of breast tissues into normal, malignant and benign. The methodology comprises of five stages. First step is preprocessing, texture feature extraction using Local quinary pattern for classifying breast tissues into normal and abnormal, Automatic segmentation of mass using k means algorithm, a new geometric feature descriptors extraction to classify them into benign and malignant and two stage classification. Our feature extraction method attained 99.27 for normal and abnormal, 79.41% for benign and malignant and over all accuracy for three class classification is 89.05%.

First time a theoretical approach towards the enhancement of spatial and angular Goos-Hanchen (GH) shift and Imbert-Fedorov (IF) shift for a Gaussian beam and Laguerre-Gaussian beam are observed, designed and simulated in four layer Kretschmann-Raether geometry at a free space wavelength of 1550 nm. Here the proposed configuration comprises a ZnSe prism and a liquid crystal layer of E44 between two silver layers through which spatial and angular GH shift and IF shift can be observed for Gaussian beam as well as Laguerre-Gaussian beam whereas the exact output beam position can only be accurately identified with the composite effect of spatial and angular GH shift and IF shift. Here with the variation of incident angle from 400 to 500, the spatial and angular GH shift and IF shift have been calculated for two types of beams. This idea expedites the concept of optical tuning at μm ranges and reveals the exact output beam position for every experiments with different beams.

Adaptive filtering and system identification by traditional derivative based algorithms create stability issues when used in infinite impulse response (IIR) systems. In this paper, the identification of IIR system is used as an optimization task. A modification is approached to cat swarm optimization by introducing the concept of craziness to produce Crazy cat swarm optimization(Crazy-CSO) algorithm. The new modified version of the algorithm has been utilized to find a better solution. The efficiency of the modified algorithm is verified by identification of few standard IIR systems through simulation study. The new method exhibits finer identification performance as compared to particle swarm optimization (PSO) and cat swarm optimization (CSO) based identification by providing superior outputs.

This paper presents a survey on distributed fiber-optic sensors (DFOS) and their performances features. Distributed fiber optic sensors are becoming increasingly popular for long range sensing applications such as monitoring temperature in hydrocarbon supply lines (oil and gas pipeline), structural health monitoring of civil structures, strain monitoring of dam and bridges etc. Moreover, these sensors are embedded with the composite materials for realtime estimation of temperature and strain vibration in civil structures. Nowadays, a lot of research is going on the development of distributed fiber-optic sensor and many are commercialized by several industries. We have made a survey on fiber-optic distributed sensors using scattering principles as well as their performances such as sensing accuracy, sensing resolution, sensing range and spatial resolution for different sensing applications.

A new wideband capacitive fed microstrip antenna using parasitic patch for wideband applications is proposed. The objective of the work is to design a wideband rectangular microstrip antenna for covering wireless Mobile Applications. To enhance the impedance bandwidth, capacitive gap-coupled mechanism has been proposed. The proposed antenna geometry describes a coplanar capacitive fed microstrip antenna printed over a FR4 substrate of thickness 1.6mm, air gap 9.0mm and permittivity r = 4.4. The capacitive feed strip used here is basically formed from a microstrip transmission line. The proposed antenna exhibits a much higher impedance bandwidth in the range of 1.49-2.45GHz an impedance bandwidth of 60.75% for return loss of less than 10dB. The proposed antenna possesses the bandwidth 960MHz with a good gain of 5.3dB overall the GPS (1575MHz) PCS (1900MHz), mobile (1800/1900MHz), UTMS (2100MHz) and Bluetooth (2400MHz) operation. HFSS high frequency simulator is employed to analyze the proposed antenna and simulated results on the return loss, VSWR, bandwidth and Gain of the proposed antenna are presented at various parasitic structure.

This paper deals with measurement of projectile velocity from the shockwave signature generated due to supersonic motion of projectiles. Two measurement methodologies have been developed. In the first case, single piezoelectric sensor is used. The time duration of N wave gives the velocity information. In the second case, by using two sensors, from the time of arrival value, the velocity of the projectile has been computed. This paper also covers the spectrum analysis of shock wave signature using Fast Fourier Transformation (FFT) in MATLAB. The velocity results obtained using above two methods is compared with the velocity obtained using Continuous wave (CW) radar systems. From the comparison results, it is found that the second method which is based on the time of arrival measurement is more accurate. The average velocity measurement error using this method with respect to radar results is found to be of the order of 0.36%.
