The survey contains more than 1300 X-ray detections at low and intermediate Galactic latitudes and covering ... -
A MULTIPHASE FLOW LOOP DESIGN FOR INVESTIGATING THE PARTIAL PHASE SEPARATION IN A PIPE TEE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)This article presents a design and commissioning of a multiphase flow loop, which was developed for scrutinizing the partial phase separation characteristics of pipe Tees. Its length is 9m and its primary diameter is 0.078m ... -
A MYOELECTRIC PROSTHETIC ARM CONTROLLED BY A SENSOR-ACTUATOR LOOP
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2014)This paper describes new methods and systems designed for application in upper extremity prostheses. An artificial upper limb with this system is a robot arm controlled by EMG signals and a set of sensors. The new multi-sensor ... -
A Network Simulation Tool for Task Scheduling
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)Distributed computing may be looked at from many points of view. Task scheduling is the viewpoint, where a distributed application can be described as a Directed Acyclic Graph and every node of the graph is executed ... -
A Neural Network Model for Predicting NOx at the Mělník 1
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2012)This paper presents a non-conventional dynamic neural network that was designed for real time prediction of NOx at the coal powder power plant Mělnik 1, and results on real data are shown and discussed. The paper also ... -
A NEW AND ADAPTIVE SECURITY MODEL FOR PUBLIC COMMUNICATION BASED ON CORRELATION OF DATA FRAMES
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2019)Recent developments in communication and information technologies, plus the emerging of the Internet of Things (IoT) and machine to machine (M2M) principles, create the need to protect data from multiple types of attacks. ... -
A New Concept of PTP Vector Network Analyzer
(IEEE, 2004-12)A new concept for vector network analyzers design based on a perturbation two-port (PTP) is presented. The approach uses redundant states of the PTP. The best states of the PTP for a certain place in Smith chart and frequency ... -
A NEW FASTENER TO ENSURE THE RELIABILITY OF A PASSENGER CAR BODY ON A TRAIN FERRY
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)To ensure the strength of the passenger car bodies during transportation on train ferries, it is proposed to mount fastening elements of chain binders on the body bolster beams. The principle of such an element is based ... -
