The concept of Cooperative Positioning (CP) has emerged recently to improve the quality of positioning, provided by Global Navigation Satellite System (GNSS), in terms of accuracy and availability. This is necessary to meet the requirements of the vehicular position-based applications such as collision avoidance, which cannot rely only on GNSS performance. CP systems are based on fusing data fr...

This paper presents low-level models of cellular LTE signals along with an architecture for a software-defined radio (SDR) that is capable of (1) extracting the essential parameters for navigation from the received LTE signals and (2) acquiring and tracking real LTE signals transmitted from multiple base stations. Moreover, a method for obtaining time-of-arrival (TOA) estimates that is highly r...

With the development of iono-free solution, provision of IGS orbit and clock products, high precision GNSS positioning with a single receiver, usually named Precise Point Positioning (PPP), has been playing an increasingly important role in many applications. PPP is to obtain the highly precise coordinates of the receivers, so it is necessary to establish the mathematical model according to the...

Motion capture setups are used in numerous fields. Studies based on motion capture data can be found in biomechanical, sport or animal science. Clinical science studies include gait analysis as well as balance, posture and motor control. Robotic applications encompass object tracking. Today's life applications includes entertainment or augmented reality. Still, few studies investigate the posit...

In the new era of wireless communication, Wireless Local Area Network has emerged as one of the key players in the wireless communication family. It is now a trend to develop the WLAN in various colleges and office campuses for increasing productivity and quality of goods. There are many obstacles when deploying WLAN, which demands seamless indoor handover. The objective of the work reported he...

Literature indicates that centrality is correlated with learners’ engagement in MOOCs. This paper explores the relationship between centrality and performance in two MOOCs. We found one positive and one null correlation between centrality and grade scores at the end of the MOOCs. In both MOOCs, we found out that learners tend to communicate with learners in different performance groups. This su...

a new way of thinking is influencing the behaviour of both consumers and firms: any tourism activity has a sizeable environmental impact and the roots of environmental problems in this industry lie inhuman behaviour. accordingly, in recent years tourists have been taking into account the environment as afactor in their purchasing decisions and firms are using this factor in their competitive po...
