Surrogate Modelling for Oxygen Uptake Prediction Using LSTM Neural Network

2023

Oxygen uptake (V˙O2) is an important metric in any exercise test including walking and running. It can be measured using portable spirometers or metabolic analyzers. Those devices are, however, not suitable for constant use by consumers due to their costs, difficulty of operation and their intervening in the physical integrity of their users. Therefore, it is important to develop approaches for the indirect estimation of V˙O2-based measurements of motion parameters, heart rate data and application-specific measurements from consumer-grade sensors. Typically, these approaches are based on linear regression models or neural networks. This study investigates how motion data contribute to V˙O2 …

Redesign enterprise network by local Internet breakout : case study

2015

Nowadays, the popularity of cloud-based services around the web and SaaS applications are empowering customers to improve their business processes and increase user productivity while reducing the company’s IT operation costs. The local Internet breakout solution provides improved performance when accessing cloud-based applications along with a greater user experience. The reason behind this is not having data travel through the corporate WAN to access the Internet at a single point. This new network design solution not only improves user experience by lower latency when accessing the Internet, but also offloading the applications traffic from corporate WAN connections. The main theme of th…

THE DEVELOPMENT OF BUSINESS LOGISTICS CONCEPT. FROM OPERATIONAL MANAGEMENT OF LOGISTICS PROCESSES TO THE INTEGRATED FLOW MANAGEMENT WITHIN THE SUPPLY…

2019

Background: Firms constantly search for ways enabling them to achieve and maintain longterm competitive advantage. Among the most significant concepts influencing the achievement of such an advantage by a firm, an important role is played by the business logistics concept. The aim of the chapter is to identify the most important stages of the logistics concept development, ranging from the operational management of logistics processes to the integrated flow management throughout the entire supply network. Methods: The chapter has a conceptual character. A review of significant works devoted to the development of the logistics concept in business was carried out. Within the chapter there is …

Proximity Effect in Superconducting Heterostructures with Strong Spin-Orbit Coupling and Spin Splitting

2019

It has been shown that singlet Cooper pairs can be converted into triplet ones and diffuse into a ferromagnet over a long distance in a phenomenon known as the long-range proximity effect (LRPE). This happens in materials with inhomogeneous magnetism or spin-orbit coupling (SOC). Most of the previous studies focus on the cases with small SOC and exchange field. However, the physics was not clear when SOC and exchange field strength are both much greater than the disorder strength. In this work, we consider a two dimensional system with a large Rashba-type SOC and exchange field in the case where only one band is partially occupied. We develop a generalized quasiclassical theory by projectin…

When modelling mobile radio channels with moving scatterers, it is generally assumed that the angles of departure (AODs), angles of arrival (AOAs), and the speed of the scatterers are time-invariant. However, this assumption is violated as the AODs and AOAs vary with the positions of t…

Predictive control of networked systems with communication delays

2012

This paper studies the problem of predictive output feedback control for networked control systems with random communication delays. A networked predictive control scheme is employed to compensate for random communication delays, which mainly consists of the control prediction generator and network delay compensator. Furthermore, a new strategy of designing the time-varying predictive controller with mixed random delays for networked systems is proposed. Then the system can be formulated as a Markovian jump system. New techniques are presented to deal with the distributed delay in the discrete-time domain. Based on analysis of closed-loop networked predictive control systems, the designed p…

Self-regulation mechanism of an ecosystem in a non-Gaussian fluctuation regime

1996

We study a dynamical model for an ecological network of many interacting species. We consider a Malthus-Verhulst type of self-regulation mechanism. In the framework of the mean field theory we study the nonlinear relaxation in three different cases: (a) towards the equilibrium state, (b) towards the absorbing barrier, (c) at the critical point. We obtain asymptotic behavior in all different cases for the time average of the process. The dynamical behavior of the system, in the limit of infinitely many interacting species, is investigated in the stability and instability conditions and theoretical results are compared with numerical simulations. \textcopyright{} 1996 The American Physical So…
