X3D sensor-based thermal maps for residential and commercial buildings
Proceedings of the 20th International Conference on 3D Web TechnologyFelix G Hamza-Lup, Paul Borza, Dorin Dragut, Marcel Maghiar

There are many building energy simulation systems on the market today; however, most of them rely on theoretical thermal models to make decisions on the building structural design and modifications. Sustainable methods of construction have made tremendous progress in the recent decades. The example of the German Energy-Plus-House technology uses a combination of (almost) zero-carbon passive heating technologies. A web-enabled X3D simulation system coupled with a cost-effective set of temperature/humidity sensors can provide valuable insights into building design, materials and construction that can lead to significant energy savings, an improved thermal comfort for residents and improved efficiency. We propose a cost effective hardware-software prototype system that can provide real data driven 3D thermal maps for residential buildings. The system can easily scale to provide 3D thermal maps for large commercial buildings.

External beam X-ray therapy (XRT) and proton therapy (PT) are effective and widely accepted forms of treatment for many types of cancer. However, the procedures require extensive computerized planning. Current planning systems for both XRT and PT have insufficient visual aid to combine real patient data with the treatment device geometry to account for unforeseen collisions among system components and the patient.

The past decade has seen the advent of numerous building energy efficiency visualization and simulation systems; however, most of them rely on theoretical thermal models to suggest building structural design for new constructions and modifications for existing ones. Sustainable methods of construction have made tremendous progress. The example of the German Energy-Plus-House technology uses a combination of (almost) zero-carbon passive heating technologies. A web-enabled X3D visualization and simulation system coupled with a cost-effective set of temperature/humidity sensors can provide valuable insights into building design, materials and construction that can lead to significant energy savings and an improved thermal comfort for residents, resulting in superior building energy efficiency. A cost-effective hardware-software prototype system is proposed in this paper that can provide real-time data driven visualization or offline simulation of 3D thermal maps for residential and/or commercial buildings on the Web.
Hybrid Courses and Associated Distributed Learning Paradigms

Current learning management system (LMS) are distributed learning environments that allow administration, documentation, tracking and delivery of educational programs worldwide. LMSs are targeted mainly towards online learning delivery but they also support hybrid forms. In this paper we present a brief review of current trends in LMS development and a case study targeted at student-student interaction improvement. We show how the hybrid version of a course can overcome some of the challenges associated with student retention, as well as present specific web-based tools and methods that can positively impact student learning and interaction. The experimental results prove that student retention can be improved by adopting specific early warning systems while student learning is positively affected through the employment of specific tools available in the LMS.
