In this study, we examine some properties of Salkowski curves in $\mathbb{E}^{3}$. We then make sense the angle $(nt)$ parametric equation curves. provide relationship between and binormal vector Darboux Through angle, obtain unit direction curve. Finally, calculate modified orthogonal frames with both curvature torsion give relationships Frenet frame

Hilbert frames theory have been extended to frames in Hilbert $C^*$-modules. The paper introduces equivalent $*$-frames and presents ordinary duals of a constructed $*$-frame by an adjointable and invertible operator. Also, some necessary and sufficient conditions are studied such that $*$-frames and ordinary duals or operator duals of another $*$-frames are equivalent under these conditions. W...

Current theories of second-order motion perception postulate that such motion is detected by either a high-level mechanism which computes the temporal correspondences between "features" extracted from the image, or low-level motion mechanisms which operate on a nonlinear, neural transformation of the luminance profile of the image. Theories which favour the latter strategy either suggest that f...

in this study, for evaluating ductility of ordinary concentrically braced frames (ocbfs) and special concentrically braced frames (scbfs) which are x- braced in two adjacent middle spans, 16 steel ordinary concentrically braced frames and 16 special concentrically braced frames are studied. the results confirm that, although most of ordinary concentrically braced frames, which are x-braced, can...

Most of the well known and widely used pitch determination algorithms are frame-based. They only consider the speech local stationarity within the analysis frame. However, our novel pitch determination algorithms employ the steerable lters to obtain the direction of pitch change. Therefore, the proposed algorithms not only make full use of the information within an analysis frame, but also opti...

This study examined orientation specificity in long-term human memory for environmental spaces. Twenty participants learned an immersive virtual environment by walking a multi-segment route in one direction. The environment consisted of seven corridors within which target objects were located. In the testing phase, participants were teleported to different locations in the environment and were ...

Two experiments investigated whether the spatial reference directions that are used to specify objects' locations in memory can be solely determined by layout geometry. Participants studied a layout of objects from a single viewpoint while their eye movements were recorded. Subsequently, participants used memory to make judgments of relative direction (e.g., "Imagine you are standing at X, faci...

We present an approach for identifying the most walkable direction for navigation using a hand-held camera. Our approach extracts semantically rich contextual information from the scene using a custom encoder-decoder architecture for semantic segmentation and models the spatial and temporal behavior of objects in the scene using a spatio-temporal graph. The system learns to minimize a cost func...
