The Ministry of Research, Technology and Higher Education Indonesia routinely hosts a competition payload tracking system placed on rocket with Ground Control Station (GCS), known as Kompetisi Muatan Roket dan Indonesia. Fixed GCS antenna causes some problems, including poor communication between GCS, position detection the payload. This research was conducted to create capable moving towards p...
today the image of a permanent skeletal space of cities affected by some forces or mechanisms is put in time with social-economic development and while imposes a new face and perspective to physical anatomy of cities, and prepares field to changes in content and social- economic structures of cities too. simultaneously with quitting villages in order to settle in cities by villagers, the phen...
Formation micro imager (FMI) can directly reflect changes of wall stratums and rock structures. Conventionally, FMI images mainly are analyzed with manual processing, which is extremely inefficient and incurs a heavy workload for experts. Iranian reservoirs are mainly carbonate reservoirs, in which the fractures have an important effect on permeability and petroleum production. In this paper, a...
background: this study assessed the relationship between working memory capacity and auditory stream segregation by using the concurrent minimum audible angle in children with a diagnosed auditory processing disorder (apd). methods: the participants in this cross-sectional, comparative study were 20 typically developing children and 15 children with a diagnosed apd (age, 9–11 years) according t...
In this paper, an improved azimuth angle estimation method with a single acoustic vector sensor (AVS) is proposed based on matched filtering theory. The proposed method is mainly applied in an active sonar detection system. According to the conventional passive method based on complex acoustic intensity measurement, the mathematical and physical model of this proposed method is described in det...
wireless sensor networks (wsns) are one of the most interesting consequences of innovations in different areas of technology including wireless and mobile communications, networking, and sensor design. these networks are considered as a class of wireless networks which are constructed by a set of sensors. a large number of applications have been proposed for wsns. besides having numerous applic...
Surface roughness is an important factor in many soil moisture retrieval models. Therefore, any mischaracterization of surface parameters (root mean square height, RMSH, and correlation length, ?) may result unreliable predictions estimations. In environments, but particularly agricultural settings, show different behaviours with respect to the orientation or azimuth. Consequently, relationship...
This paper presents the development and experiment of three-dimensional image formation by using a ground-based tomographic synthetic aperture radar (GB-TomoSAR) system. GB-TomoSAR formulates two-dimensional synthetic aperture by the motion of antennae, both in azimuth and vertical directions. After range compression, three-dimensional image focusing is performed by applying Deramp-FFT (Fast Fo...
