Acoustical behavior of a room for a given position of microphone and sound source is usually described using the room impulse response. If we rely on the standard uniform sampling, the estimation of room impulse response for arbitrary positions in the room requires a large number of measurements. In order to lower the required sampling rate, some solutions have emerged that exploit the sparse r...

Recently joint radar communication (JRC) systems have gained considerable interest for several applications such as vehicular communications, indoor localization and activity recognition, covert military satellite based remote sensing. In these frameworks, bistatic/passive deployments with directional beams explore the angular search space identify mobile users/radar targets. Subsequently, link...

A three-dimensional finite element model of the articular disc of the human temporomandibular joint has been developed. The geometry of the articular cartilage and articular disc surfaces in the joint was measured using a magnetic tracking device. First, polynomial functions were fitted through the coordinates of these scattered measurements. Next, the polynomial description was transformed int...

By “parallelogram geometry” we mean the elementary, “commutative”, geometry corresponding to vector addition, and by “trapezoid geometry” a certain “noncommutative deformation” of the former. This text presents an elementary approach via exercises using dynamical software, hopefully accessible to a wide mathematical audience, from undergraduate students and high school teachers to researchers, ...

Supervised learning depth estimation methods can achieve good performance when trained on high-quality ground-truth, like LiDAR data. However, only generate sparse 3D maps which causes losing information. Obtaining ground-truth data per pixel is difficult to acquire. In order overcome this limitation, we propose a novel approach combining structure information from promising Plane and Parallax ...

the subject of geometry and proportions has been regarded as an issue which has a close relationship with architecture. since the entire universe, living beings and the human geometry can be seen clearly, that’s why our unconscious essence has accustomed to these proportions whereby reflection of this mentality can be seen in the architect’s hands and thought in the architecture. it can witness...
