Abstract The demand for smartphone positioning has grown rapidly due to increased accuracy applications, such as land vehicle navigation systems used tracking, emergency assistance, and intelligent transportation systems. integration between is necessary maintain a reliable solution. High-end inertial sensors are not preferred their high cost. Smartphone microelectromechanical (MEMS) attractive...

The positive effect that innovative techniques have has been a broad debate in recent years especially the matter of teaching reading comprehension. Semantic map is one latest used to develop current study attempts provide more detailed investigation regarding effects using semantic on students' comprehension achievement. To investigate objective this paper, null hypothesis claiming there no st...

This paper proposes a new wireless-signal map-matching technique for calibrating non-line-of-sight positioning error in urban environments. Compared with conventional map-matching methods that utilise a continuously-tracked single user trajectory, the proposed map-matching method utilises a considerable number of different user locations for comparison with ideal map information. By appying the...

The analysis of the hyperspectral image is an important method used in mineral detection. A map Feldspar will produced for study area, which lies to west holy province Karbala and limited that download from USGS website (type EO-1 satellite) , by using Spectral Angle Mapper (SAM) technique Erdas software, based on calculating spectral reflection curve any point feldspar available library softwa...

Over the past decade, chaotic systems have found their immense application in different fields, which has led to various generalized, novel, and modified systems. In this paper, general jerk equation is combined with a scaled sine map, been approximated terms of polynomial using Taylor series expansion for exhibiting behavior. The paper based on numerical simulation experimental verification sy...
