By using suitable trigger elements,…

In this article, a new method to extract the RLC parameters from the structure of a Rotating Traveling Wave Oscillator (RTWO) is described. The use of a 3D simulator (EMPRO) allow us to develop a precise analysis of the impact of the topology, the geometrical discontinuities, and the dimensions of the transmission lines, on the…

The Industrial Internet of Things (IIoT), a typical use case of the Internet of Things, has been a great prospect for development in the near future. In the developing fifth generation mobile communications, the IIoT is an extremely important application case. In this paper, the channel propagation properties are researched and modeled based on the…

Requirement for pole-changing motors emerged at the very early times of asynchronous motor design. Different solutions have been elaborated and some of them are generally used. One of these solutions in use is the so called pole phase modulation method. The so called 3 Y / 3 Y pole-changing winding being subject of this paper…

This paper refers to a novel mixed-mode universal biquad employing plus current output differential voltage current conveyors with grounded passive components. The circuit performs mixed-mode operation with the selection of the input and output terminals, and it enables low-pass, band-pass, high-pass, band-stop and all-pass responses choosing suitable input signals. The circuit needs no component matching…

This paper introduces a design process for developing a humanoid mobile robot, namely VieBot. Stemming from the design process, it is easy to adjust the design and extent robot behaviors to meet customer needs. Our key solution is to split the design into three modules related to robot behavior, kinematic computation and motion control. Base…

Four different soundscapes with different loudness and spectral distributions were recorded in Zagreb (capital of Croatia) and reproduced to two groups of listeners while they were performing a concentration demanding task – a simplified variation of the memory game. These two groups of test subjects listened to the same soundscapes but with different loudness distribution.…

In this research human gait database is collected using different possible methods such as Wearable sensors, Smartphone and Cameras. For a gait recognition accelerometer data from wearable shimmer modules and smartphone are used. Data from different sensors location is compared to know which sensor location have better recognition rate. Different walking scenarios like slow, normal…

A Digital Terrain Model (DTM) is a digital model representing the earth ‘s surface topography in three dimensions (3D) while a Digital Surface Model (DSM) represents the whole terrain including the objects on it such as trees and buildings. DTMs can be created through stereo-plotting. The advantage of this method is that the 3D data…

Selection of a routing protocol is vital for modern arena of Internet communication as network traffic and network complexities are rapidly increasing. This paper evaluates the effectiveness of three routing protocols namely routing information protocol version 2 (RIPv2), open shortest path first (OSPF), enhanced interior gateway routing protocol (EIGRP), and hybrid protocols based on these…
