Predictive models play an important role in the design of post-combustion processes for the capture of carbon dioxide (CO2) emitted from power plants. A rate-based absorber model is presented to investigate the reactive capture of CO2 using aqueous monoethanolamine (MEA) as a solvent, integrating a predictive molecular-based equation of state: SAFT-VR SW (Statistical Associating Fluid Theory-Va...

Knowledge of the phase behavior of mixtures of oil with carbon dioxide and water is essential for reservoir engineering, especially in the processes of enhanced oil recovery and geological storage of carbon dioxide. However, for a comprehensive understanding, the study of simpler systems needs to be completed. In this work the system (n-decane + carbon dioxide + water) was studied as a model (o...

This paper presents an empirical study on two different navigation styles within QuickTime VR panorama scenes. In one style, the users would jump from one position in the scene to the next while maintaining their direction of view. In the second style, the users would jump from one position to the next and reverse their direction of view. The results show that participants preferred the later s...

In this work the solubility of 15 amino acids and 18 peptides in aqueous 2-propanol solutions was successfully modelled using PC-SAFT that used recently determined experimental melting properties as input data.

Recent developments in Virtual Reality (VR) technology present a tremendous opportunity for the tourism industry. This research aims to better understand how the VR experience may influence travel decision making by investigating spatial presence in VR environments and its impact on attitudes toward tourism destinations. Based on a study involving virtual walkthrough of tourism destinations wit...

Nowadays, the development of a Virtual Reality (VR) application is still very time-consuming and hard for a non VR-expert. In addition, the VR applications often lack the necessary semantic information to make the VR application more intuitive and more attractive for the end-user. This paper describes a new approach for designing VR applications using ontologies, which make the design of the VR...

BACKGROUND Mechanism and effects of vagal response (VR) during cryoballoon ablation procedure on the cardiac autonomic nervous system (ANS) are unclear. The present study aimed to evaluate the relationship between VR during cryoballoon catheter ablation for atrial fibrillation and ANS modulation by evaluating epicardial adipose tissue (EAT) locations and heart rate variability (HRV) analysis. ...

BACKGROUND Virtual reality (VR) and physical model (PM) simulators differ in terms of whether the trainee is manipulating actual 3-dimensional objects (PM) or computer-generated 3-dimensional objects (VR). Much like video games (VG), VR simulators utilize computer-generated graphics. These differences may have profound effects on the utility of VR and PM training platforms. In this study, we ai...

OBJECTIVE To investigate the effects of using motor imagery (MI) in combination with a virtual reality (VR) program on healthy volunteers and stroke patients. In addition, this study investigated whether task variability within the VR-guided MI programs would influence corticomotor excitability. METHODS The present study included 15 stroke patients and 15 healthy right-handed volunteers who w...

3D interfaces allow easy and intuitive human-computer communication. These 3D interfaces are most often used in the virtual reality (VR) and VR systems. This fact was the reason for creation of this dissertation thesis which focuses on the formal description of the process of VR system creation. Thesis is divided into five sections. The first section presents the current state of the VR, 3D int...
