Human fingertips are densely populated with tactile receptors and are hence incredibly sensitive.However, wearing gloves on the fingers drastically reduces the tactile information available to the fingertips, such as the texture and shape of the object, and makes it difficult to perform dexterous work.As a solution, in this study, we developed a hi

The size of cities has been continuously increasing because of urbanization.The number of public and private transportation vehicles is rapidly increasing, thus resulting in traffic congestion, traffic accidents, and environmental pollution.Although major cities have undergone considerable development in terms of transportation infrastructure, prob

In this article, a broadband 3-dB directional coupler is proposed using groove gap waveguide (GGW) structures.Gap waveguide jilungin dreaming tea technology has been introduced to overcome manufacturing and assembling challenges of different millimeter-wave components and devices.The presented coupler has wideband coupling flatness with low return

The ready-mixed discount greenery concrete is subject to certification in accordance with the compliance system 2+.Manufacturers of concrete are required to implement factory production control and then to certify concrete, which is subject to the national mark B.The paper presents the results of strength tests of C 40/50 concrete samples.Designed

Longitudinal bunch shaping is gaining increasing attention due to the large impact it has on modern accelerators.The existing methods for controlling the density profile fall into three categories: laser shaping, emittance exchange, or correlations between the energy and one of the other coordinates.These methods require either (i) dispersive eleme
