Lip area detection and extraction is essential for many applications like facial expression, lip reading and visual speech recognition. In general, the lip segmentation in color image is a tedious task because the color difference between lip and skin region is not so apparent sometimes, which is a major issue in lip reading system. The objective of this work is to provide the solution to the problem of lip segmentation from the video using Image Processing techniques. In this work, Otsu based thresholding and mid-point based lip segmentation is carried out. The performance of the proposed technique is evaluated by testing it on 20 different videos which are taken under standard condition. From the results it is observed that, the proposed method has achieved 98% of success rate for lip segmentation.

Wireless communications and MEMS are the two technologies that have resulted in the development of wireless sensor networks, which are highly distributed networks with the deployment of small, inexpensive nodes. The flexibility of installation and configure ration has greatly improved resulting in a flurry of research activities commencing in the field of sensor networks. This paper studies the routing protocols for WSNs and presents a comparison of the representative routing protocols. At last, several issues that are to be addressed are put forward.

Agriculture plays an important role in economy of India. More than half of the population in India depends on Agriculture. It provides raw material for many industries. Early more than half of the land mass is used for Agriculture and over the years there is decline in agriculture land. Various factors like urbanization and development results in the growth of Non-Agriculture land year by year. Agriculture is the largest abstractor and prime consumer of ground water resources across globe and hence study of agro-economies that is ground water dependent became widely popular. Agriculture Irrigation, Surface water and Ground water resources are interlinked to each other. Water Usage and Food Production are dependent on each other extensively. Water is the major parameter that controls the crop yield. Many countries agriculture yield depends on rain fall. Many at time’s rainfall is not sufficient to crop yields. It made researchers to do rigorous analysis on water resource availability and suggest farmers for its effective utilization. This paper aims at development and application of new Hybrid Data Mining (HDM) Techniques for effective analysis of Land Surface Water Resources (LSWR) like Canals, Tube wells, Tanks and other water resources. Apart from that analysis is also made on Various Agriculture yield’s i.e., both for Cereals and Millets namely Kharif, Rabi, Sugarcane, Maize, Ragi, Wheat, Barley, etc., using new Hybrid Data Mining (HDM) techniques. To model the complex logic, Decision Tables (DT) is used. The results were proved to be good when new Rough Set Based Hybrid Data Mining (RSBHDM) Techniques are applied over the refined data sets.

In a computer numerical control (CNC) milling process, simulation is integral to ensure that the resulting work piece has very little error. This boils down to the accuracy and effectiveness of the G-code generated by the simulation in comparison with the actual CNC milling process. This study presents a system revolving around augmented reality (AR) programming to assist in the generation of G-codes for a virtual CNC milling simulation process. The proposed system allows the operator to understand the relation between G-codes and the position of the cutter through AR-based simulation. The system can be used to train novice machinists and observe the milling simulation before the actual machining operations. The G-code generation is based on a tracking and registration algorithm that calculates the related coordinates aided with a heads-mounted-display (HMD). The coordinates are saved on a separate file, which contains the coordinate of the cutter and current material removal rate (MRR), and transferred to a G-code program. The generated codes are then validated with commercially available simulation tools and it was found that only a deviation of no less than 5% exist, proving that the developed methodology is a viable method to substitute conventional means for simulating CNC milling.

In this paper we present an application of Alternating Direction Solver (ADS) for solution of non-stationary PDE-s with isogeometric finite element method. We illustrate this approach by solving examplary non-stationary three-dimensional problemusing explicit Euler scheme. In particular we focus on the difficult problem of non-linear flow in heterogenous media.

In recent years, along with stagnating wage and souring price index, consumers have grown awareness of shopping behaviors and rights of purchase. More and more retailers strengthen businesses by sustaining quality control and improvement for continuing profits. This paper intergrades the model of Parasuraman, Zeithaml and Berry (PZB) customer services as a measure with retail service quality scale (RSQS), and adopts fuzzy analytic hierarchy process (FAHP) to further analyze possible problems and performances of drugstores. By the criteria based on literature reviews and the interviews with experts, this paper provides results that reveal what consumers most concern-customer oriented resolution. On the contrary, what consumers weigh the least are on physical aspects. As a result, businesses must reinforce the quality of customer services and competitiveness.
