Increasing demands of process automation for un-manned manufacturing attracted many researchers in the field of on-line monitoring of machining processes. In view of this, extensive research work is taking place world-wide in the area of on-line tool condition monitoring system (TCMS). Tool wear is the most undesirable characteristic of machining processes as it adversely affects the tool life, which is of foremost importance in metal cutting owing to its direct impact on the surface quality of the machined surface, and its dimensional accuracy, and consequently, the economics of machining operations. Therefore, methods for cutting tool wear sensing are crucial in view of the optimum use of cutting tools. With an effective monitoring system, the damages to the machine tool, downtime and scrapped components can be avoided. This paper provides brief overview on tool condition monitoring. © 2015 Elsevier Ltd.

With the rapid spread of radio communication network including cellular phone, Radar Communication System, Navigation, Internet Communication Satellite communication etc., the ANTENNA is basic device which is used in all communication systems. Its proper design is essential to run those systems effectively and gainfully. Conspicuously wide antennas for various transmitting and receiving stations installed on steel towers, suburbs and on the roofs of the buildings and tops of the electrical poles and towers in the city and also in rural area. Thus antenna is the backbone of the any radio wave and microwave communication system. The antenna is usually lightweight, low cost, easily machinable electrically good conductor device. It is mainly divided into two groups (1) External antenna and (2) Internal antenna. External antenna is large in size, material cost is also high and in practice it has more radiation losses. It can be reduced by modern design techniques but its shape and size again incorporates a major problem while interface with the communication devices. However, internal antenna brought in to practice so that, it is easily interface with the any communication system. Numerous design techniques have been used from many years to design the perfect and proper internal antenna. Thus internal antenna is proven benchmark device used in the wireless communication system. Well-known antenna widely used in this area which is known as MICROSTRIP ANTENNA. This paper mainly focuses on the design of miscrostrip antenna to meet the industrial design problems so that it works properly and precisely. Many more design tools and techniques have been used to getting progressive performance of it. As the operating microwave frequency changes or fixed the designed antenna with respect to derived parameters may not give satisfactorily performance. The skilled or expert designer on his experience does changes in the derived design parameters and complete the task so that perfect fitting of the parameters (Patch width W, Length L substrate density etc. ) resulting increases its performance. Hence it translates the designer's knowledge into correct parameter setting. The paper describes proposed work to design and develop a Microstrip Antenna employing conventional mathematical model design which acquires constant environmental conditions for propagation of microwave. In this paper Fuzzy logic technique is effectively used to design and development of miscrostrip antenna which is based on the fuzzy set theory. Also it is proposed to develop Fuzzy Inference System (FIS) on the basis of expert design knowledge and experience. Finally test performance of the conventional design of microstrip antenna and fuzzy based design antenna has been compared. To avoid computational complications it is proposed to use the computer with MATLAB software. It is also proposed that designed microstrip antenna properly interfaced and then it will be tested for performance. Unique computer program also (source code) developed which is useful to fast and easy computation work. In actual practice of this work, Patch length L and width W is taken as input variables and frequency as output variable in the FIS. This paper concludes that fuzzy based design and developed technique is found to be most suitable for betterment of miscrostrip antenna. © 2015 IEEE.

This paper presents a no-reference image quality assessment, targeted towards blur distortions based on the study of human blur perception for varying contrast values. A probabilistic framework is developed based on the sensitivity of human blur perception at different contrasts. Utilizing this framework, the probability of detecting blur at each edge in an image is estimated. The blur perception information at each edge is then pooled over the entire image to obtain a final quality score by evaluating the cumulative probability of blur detection. Proposed metric is able to predict relative amount of blurriness in images. Higher metric value represent less blurred image. Results are provided to illustrate the performance of proposed metric. Performance of proposed metric is compared with existing no reference image quality metric for various publically available image databases. © 2013 IEEE.

Many classes of images contains spatial regions which are more important than other regions. Compression methods which are capable of delivering higher reconstruction quality are attractive in this situation for the important parts. For the medical images, only a small portion of the image might be diagnostically useful, but the cost of a wrong interpretation is high. Hence, Region Based Coding (RBC) technique is significant for medical image compression and transmission. Lossless compression in these 'regions' and lossy compression for rest of image can helps to achieve high efficiency and performance in telemedicine applications. This paper proposes an automated, efficient and low complexity, lossless, scalable RBC for Digital Imaging and Communications in Medicine (DICOM) images. The advantages of RBC are exploited in this paper, segmenting the region into various regions of importance and subjecting varying bit-rates for optimal performance. Moreover, the combined effects of Integer Wavelet Transform (IWT) and bit-rate limiting compression technique for lesser important regions helps reconstruct the image, reversibly, up to a desired quality. The overall compression thus reaches a satisfactory level to be able to safely transmit the image in limited bandwidth over a telemedicine network and reconstruct diagnostic details for treatment, most faithfully. © 2012 The Institution of Engineering and Technology.

Design of circular annular ring patch with circular polarization for surface wave suppression by embedding electromagnetic band-gap structures in its ground plane is considered. The ground plane consists of an M-shaped EBG structure inscribed in the unit square metal patch of dimension 6. mm. ×. 6. mm with conducting vias located at centre of each EBG cell. The antenna is first designed as a simple circular annular ring patch without EBG and then in a planar and double layer form with EBG to resonate at centre frequency of 2. GHz. The circular annular ring patch when surrounded by two rows of M-shaped EBG structure shows improvement in the antenna performance parameters such as impedance bandwidth, axial ratio bandwidth and gain, in comparison to antenna without EBG structures. The circular polarization purity is excellent over the stop band of 296.2. MHz for the M-shape EBG structure. The maximum co-polarized gain is 6.77. dB and cross-polarized gain is -12.55. dB for main lobe direction. The proposed double layer antenna with M-shape EBG structure embedded in its ground plane can be a good candidate for the Mobile Satellite Service band (1990-2025) MHz and for UMTS, WCDMA (1920-2170) MHz applications. © 2016.
