Techniques Used for Eye Gaze Interfaces and Survey

Abstract: Eye movement tracking is a method that is now-a-days used for checking the usability problems in the contexts of Human Computer Interaction (HCI). Firstly we present eye tracking technology and key elements. We tend to evaluate the behavior of the user when they are using the interface of eye gaze. Used different techniques i.e. “electro-oculography, infrared oculography, video oculography, image process techniques, scrolling techniques”, different models, probable approaches i.e. “shape based approach, appearance based methods, 2D and 3D models based approach and different software algorithms for pupil detection etc”. We have tried to compare the surveys based on their geometric properties and reportable accuracies and eventually we conclude this study by giving some prediction regarding future eye-gaze. We point out some techniques by using various eyes properties comprising nature, appearance and gesture or some combination for eye tracking and detection. Result displays eye-gaze technique is faster and better approach for selection than a mouse selection. Rate of error for all the matters determines that there have been no errors once choosing from main menus with eye mark and with mouse. But there have been a chance of errors when once choosing from sub menus in case of eye mark. So, maintain head constantly in front of eye gaze monitor.

FUNGICIDAL METHYL-2-BENZIMIDAZOLE CARBAMATE ADSORPTION IN SOIL AND REMEDIATION VIA Prunus dulcis DERIVED ACTIVATED CARBON

Abstract: Carbendazim (methyl-2-benzimidazole carbamate i.e. MBC) was investigated for pedospheric adsorption-desorption, mobility and effective removal via Prunus dulcis derived activated carbon in addition to physical and chemical characterization of selected soils. MBC was adsorbed into six agriculturally soils with distinctive characteristics via batch-equilibrium method and was evaluated via linear and Freundlich models. The highest value for linear and Freundlich adsorption coefficients i.e. K d and K f (8.8 µg/mL and 11 µg/mL respectively) corresponds to soil sample 6 having organic matter (3.3 %) and clay (18 %). Soils exhibited variable affinity towards MBC adsorption with K d ranging between 6.3 to 11 µg/mLand K f ranging from 5.2 to 7.4 µg/mL, signifying weak adsorption of MBC in selected soils. Desorption for soil sample 1 was highest because all parameters favor the quicker MBC molecules detachment from soil particles deficient in organic matter. Results for current investigation were examined for statistical significance via one way analysis of variance goodness of fit determined with residual plots in Minitab. In the remediation assay, Prunus dulcis shells were used as precursors for activated carbon preparation. MBC was removed up to 100 % in the lowest concentration, i.e. 2.5 ppm, while only 23 % of MBC was removed in case of 7.5 ppm, expressing the concentration dependency of the remediation assay. Prunus dulcis shells derived activated carbon is a sustainable and non-toxic material, which opens the future arenas for further research on its commercialization potential for remediation of soil compartment.

Notice of Retraction Empirical analysis of portfolio investments in Pakistan

Abstract: Foreign private investment could play a vital role in the economic growth of developing countries, provided that governments play an active role in attracting and accelerating the benefits of foreign investment In this paper, I have used the data of some variables affecting capital & financial account from 1986 to 2006 to generate some results I have emphasized the Granger causality test and impulse response functions to analyze the dynamic influence of Foreign Portfolio Investment to the capital and financial accounts, as well as the GDP of Pakistan The results suggest that foreign portfolio investment has a negative effect on current account balance and a positive effect on capital and financial account

Executive Information Systems Based on Data Mining Techniques Modeled through Quadratic Programming

Abstract: This paper presents quadratic integer programming as a modeling technique to formulate the analytical models for financial markets. Financial market analysis has been a promising area of research for the last three decades. The proposed models aim to cater for several scenarios for analysis and prediction of future trends in capital, gold and currency markets. These models after translation into hyper graphs would be solved through clustering (data mining). The implementation of this research would be the basis of a decision support system. It may prove to be an analysis tool to evaluate the economic status of a country statistically in a more accurate manner

Scaling of spatial variation in ground flora of Tharparker, Pakistan

Abstract: The role of vegetation is very important in ecosystem conservation. The present study was conducted to classify the existing ground flora in Tharparker, Pakistan. The distribution pattern of vegetation and species association was grouped into different communities by using ordination techniques. Both direct and indirect ordination methods were applied to classify the species into groups and communities, and also quantify the relationship of species with varied soil parameters (pH, EC, moisture, OM, K, P, Fe+3, Zn+2, Mn+2, Cu+2). Plant and soil samples were randomly collected using quadrat of 1 * 1 m2. Two main groups and four communities were formed by species derived from fifty quadrat. Cynodon dactylon and Desmostachya bipinnata showed higher abundance over the broad range of all edaphic factor’s concentration. This study provided the significant results of least abundant and most abundant herbaceous species in the region of Tharparker, which will be helpful for land managing and planning.
