We present a method for navigating an autonomous agent based on the textures present in an environment. Specifically, the autonomous agent in question is that of a robotic lawn mower. If we can successfully differentiate the textures of the cut and uncut lawn surfaces, then we can track the boundary between them and mow in a pattern as a human would. The system uses the wavelet transform as the...

The study attempted to assess the impacts of brick kilns emissions on farm soil in and around kiln areas. A total 72 representative samples were collected from 12 selected clusters Rajshahi Gazipur Districts Bangladesh, covering two years (September 2015 August 2017). analyzed using standard methods. pH organic matter content found be very low. parameters such as pH, matter, texture critical co...

An interesting subclass of Noun-noun combinations in English can take two meanings depending on whether the first or second word is stressed in speech. A BRICK factory is one that makes bricks, whereas a brick FACTORY is one made of brick. An explanation is offered in terms of a bias for nouns from particular ontological categories to trigger particular semantic interpretations for a combinatio...

The classical "brick wall," which may, according to quantum mechanics, leak via tunneling, is here shown to be completely transparent when appropriate impedance matching media are placed both in front of and behind the "wall." Optical experiments involving beyond-critical-angle-tunnel barriers in the frustrated total internal reflection scheme which mimic quantum mechanical systems provide conv...

This paper presents a novel background model for video surveillance—Spatio-Temporal Patch based Background Modeling (STPBM). We use spatio-temporal patches, called bricks, to characterize both the appearance and motion information. Our method is based on the observation that all the background bricks at a given location under all possible lighting conditions lie in a low dimensional background ...

An experimental study is conducted on three ½ scales, single-story, single-bay, frame specimens. The first specimen was a reinforced concrete frame with solid-brick infill. The second specimen was a reinforced concrete frame with hollow clay perforated-brick infill. The last specimen was a reinforced concrete frame without any infill. These three specimens were tested by pseudostatic method. Di...
