This paper describes the development of a heart rate monitor system based on a microcontroller using fingertip sensor. The paper explains how a single-chip microcontroller can be used to analyze heart beat rate signals in real-time. The hardware and software design are oriented towards a single-chip microcontroller-based system, hence minimizing the size. Heart rate of the subject is measured from the finger using optical sensors and the rate is then averaged and displayed on a text based LCD.

Worldwide the incident of malignant melanoma is increasing continuously. Melanoma is the deadliest form of skin cancer. There is need of computerised system to evaluate a patient’s risk of melanoma using images of their skin lesion captured using dermatoscope due to cost of dermatologist to monitor every patient. Segmentation is performing measure role for detection of skin lesion from images. Dermoscopy images of skin cancer and other pigmented lesions are segmented using different methods. A review of different types of skin lesion segmented techniques is presented in this paper. Accuracy, speed and computational efficiency are the main aim of segmentation.

Software Data graphs encompasses the development and evaluation of methods for graphically representing different aspects of methods of software, including its structure, execution and evolution. Creating data graphs helps the user to better understand complex phenomena. It is also found by the software engineering community that a data graph is essential and important. In order to visualize the evolution of the models in Software Evolution, authors have proposed a framework which consists of areas and key features for the assessment of Software Evolution process and addresses a number of stakeholder concerns.

Highway travel is the lifeblood of modern industrial nations. The larger roads are sorely over burdened: around the major cities, heavy usage slows most peak-hour travel on freeways to less than 60 kilometers per hour. In all excessive traffic causes more than five billion hours delay every year; it wastes countless gallons of fuel and needless multiplies exhaust emission. The main goal of this paper is to make the experience of driving less burdensome and accident less, especially on long trips. This can be achieved by making the highway itself part of the driving experience and integrating roadside technologies that would allow the overburdened highway system to be used more efficiently. The automobile will have automatic throttle, braking and steering control. Here is a system to host these cars consist of roadside sensors that obtain information about current traffic condition and rely them to receives in the automobile on the road. The automobile can be grouped together at highway speeds, 65-70MPH, no more than a few feet apart, which make better use of the available roadways. In this manner, the traffic system and the automobiles work together to bring passengers safely and quickly to their destination.

Indian agriculture, even after the Green Revolution, is not as productive as it could potentially be. It calls for a second Green Revolution–one of “precision agriculture?, where cutting-edge technology is used to maximize production with minimum input costs and resources. In this paper we present a multi-purpose agricultural robot to implement precision irrigation, fertilizer addition and de-weeding, apart from continuous monitoring of crop and soil conditions. This will involve efficient utilization of water resources, intensive plant and soil monitoring, condition based use of fertilizers and the ability to work in unstructured environments. Developed agriculture needs to find new ways to improve efficiency.

Polymer portrayal in arrangement has risen as a significant analytical strategy on the grounds that numerous smaller scale basic highlights can be seen in the high goals spectra. The initial phase in the investigation of polymers is setting up the reverberation assignments. This is a significant undertaking and much exertion has been guided towards growing new methods to make the assignments. The methods incorporate correlation of the sign forces with those normal for polymerization models (Bernoullian, Markov, and so forth.), examination with model mixes, substance move computations and multidimensional NMR.
