Cormac Paterson is a student at Arlington High School. We ran into him last year while conducting research in the school. He quickly mastered our Energy3D CAD software. In as short as just five class periods, he came up with three different architectur…
Figure 1: Copy data from Energy2D.Since a few users asked if the simulation data in Energy2D can be exported to other applications such as Excel, I have added a feature to the app for extracting virtual sensor data as multi-column time series data. For…
Figure 1The International Journal of Engineering Education published our paper (“A Time Series Analysis Method for Assessing Engineering Design Processes Using a CAD Tool”) on learning analytics and educational data mining for assessing student perform…
In the winter, a fireplace is the coziest place in the house when we need some thermal comfort. It is probably something hard to remove from our living standards and our culture (it is supposed to be the only way Santa comes into your house). But is the concept of fireplace — an ancient way […]
All educational research and assessment are based on inference from evidence. Evidence is constructed from learner data. The quality of this construction is, therefore, fundamentally important. Many educational measurements have relied on eliciting, analyzing, and interpreting students’ constructed responses to assessment questions. New types of data may engender new opportunities for improving the validity and […]
Link to simulation A rocket mass heater is an innovative and highly efficient space heating system, which is popular among natural building DIYers since its invention in 1970s. A number of engineers who are interested in rocket stove design have used our Energy2D software to visualize the thermal physics involved. Link to simulation Martin Karl […]
A student designIn a pilot study conducted in December 2012, high school students in an engineering class used our Energy3D CAD tool to do an urban solar design project — they must consider the sun path in four seasons and the existing buildings in th…
The day/night cycle of an SUTThe solar updraft tower is a new-concept clean energy power plant for generating electricity from the sun. Sunshine falling on a greenhouse collector structure around the base of a tall chimney heats the air within it. The …
A Trombe wall is a sun-facing wall separated from the outdoors by glass and an air space. It consists a solar absorber (such as a dark surface) and two vents for air in the house to circulate through the space and carry the solar heat to warm the house…
In his Critique of Pure Reason, the Enlightenment philosopher Immanuel Kant asserted that “conception without perception is empty, perception without conception is blind. The understanding can intuit nothing, the senses can think nothing. Only through their unison can knowledge arise.” More than 200 years later, his wisdom is still enlightening our NSF-funded Mixed-Reality Labs project. […]
