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.

India is geographically large with many towns and villages located in remote rural areas. Few medical facilities exist to serve the large population that resides in the villages. Telemedicine is going to turn a good solution in this case to bridge the gap. There are many difficulties in front of Telemedicine in India, being developing country. This paper looks into the technological issues that are of prime concern in the growth of telemedicine services. In telemedicine various types of data is used such as text, images, audio, video etc. Out of these the use of images is prominent. In this survey, the importance and need of Image compression is discussed. A survey of different image compression techniques is discussed along with new research direction in image compression area.

mHealth is a growing concept across the globe. This is due to mobile access becoming more ubiquitous than the healthcare access in urban as well as rural areas. mHealth makes use of mobile communication technology for broad range of healthcare applications. It includes health information delivery, remote health monitoring of the patient, remote diagnosis and even remote treatment of the patients. There is a huge scope for using mobile communication technology for the development and deployment of innovative healthcare products and services. This paper presents introduction to mHealth concept. It further highlights various considerations for long term health monitoring as one of the major application area of mHealth. To demonstrate the concept, a prototype system for long term ECG monitoring is proposed. The system comprises of a 3 lead ECG device with microcontroller and Bluetooth connectivity. An Android based mobile application has been used to display wirelessly received ECG data in the form of ECG Wave. © 2015 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.
