The UWB-OFDM Channel Analysis in Frequency
2009
In this paper, the ultra-wideband channel with orthogonal frequency division multiplexing (UWB-OFDM) is analyzed in the frequency domain. For UWB-OFDM channels with log-normal fading in the time domain, we show that the amplitude of each subcarrier can be approximated by a Nakagami-m random variable, where the fading parameter, the mean power and the correlation coefficient are expressed in terms of the following parameters: time arrival of the clusters, inter-arrival time of rays inside clusters, and power decay constants of rays and clusters.
Modeling the escalation/de-escalation of response operation levels in disaster response networks using hierarchical Colored Petri Nets (CPN) approach
2018
In emergency situations, the first responders need to act promptly to situations, while the disaster management authorities' response might not be at the same speed. Delays by disaster management authorities had a direct impact on response operations led response teams to the shift away from command and control structures to net-centric ones. This paper is part of a study to examine patterns of emerging organizational relations and coordination structures in disaster response operations. Understanding coordination patterns in disaster chaos can help to integrate those patterns in the planning and execution in the modern disaster management operations. We use dynamic modeling methods to anal…
Experimental Command and Control Center for Crisis and Disaster Management: A Living-Lab Approach
2021
The living-lab is a planned research infrastructure that includes user involvement and the co-design process. This article presents an overview of the innovative experimental control room for crisis management that adopts this living-lab approach in all research co-creation activities. The aims of this paper are threefold: (1) To study possible control room research methods, focus areas, and technologies that can be tailored to the living-lab approach; (2) To illustrate and share experience on the possibilities to tailor an experimental command and control center as a living-lab. (3) To explore the features to fulfill to maximize the benefit of the living-lab for all intended audiences. By …
Design of the Biotechnological System for the Cultivation of a Polysaccharide-Producing Microorganism and Metabolites Separation
1970
This paper presents a design of the biotechnological system established for the cultivation of a polysaccharide-producing microorganism and the separation of the polysaccharide together with other metabolites. The strain used is a halophilic archaeon called Haloferax mediterranei (Mironescu et al., 2003). On designing the biotechnological system, some requirements are important: The recipients and the pipes must be resistant to the corrosion action of the cultivation substrate very rich in NaCl (125 to 150 g/l); A command and control system for pH, temperature and substrate and inoculum feeding is necessary; A system for monitoring dissolved oxygen and gases evacuated from the bioreactor (O…
Mechatronic Design of a Four-Wheel drive mobile robot and differential steering
2021
This paper presents, the development of an autonomous mobile robot with a four-wheel drive and differential locomotion. The mobile robot was developed in the Machines and Industrial Equipment Department from the Engineering Faculty of Sibiu. The main purpose of developing this type of mobile platform was the ability to transport different types of cargo either in industrial spaces or on rough terrain. Another important objective was that this platform could be driven in confined or tight spaces where a high degree of manoeuvrability is necessary. The great advantage of this type of mobile platform is the ability to navigate through narrow spaces due to the type of locomotion implemented. Th…
