Abstract: Drivable path detection is an important factor to consider for a successful development of autonomous robot which is characterized as an intelligent vehicle. Researchers using different vision-based techniques have achieved remarkable result toward drivable path detection. Regardless of this achievement, environmental noise such as rain and/or snow can cause misdetection of drivable path which can lead to autonomous robot accident. In this paper, after investigating the effects of rain and/or snow, we introduced into the drivable path detection system a filtering algorithm that addresses the detection and removal of rain and/or snow for the optimization of the system. Experiments were carried out to show the effectiveness of the filter in the system. The results show that filtering algorithm assists the autonomous driving system in navigating perfectly during rain and/or snow scenario with minimal accident.

The U.S. Department of Energy (DOE) has reviewed the 2018 edition of the International Energy Conservation Code and determined the updated edition would improve energy efficiency in buildings subject to the code compared to the 2015 edition.  First. free access to the 2018 edition is linked below:

2018 International Energy Conservation Code (IECC)

Final Determination Regarding Energy Efficiency Improvements in the 2018 International Energy Conservation Code

DOE analysis indicates that buildings meeting the 2018 IECC (as compared with buildings meeting the 2015 IECC) would result in national site energy savings of 1.68 percent, national source energy savings of 1.91 percent, and national energy cost savings of approximately 1.97 percent of residential building energy consumption.  Many colleges and universities have real assets that are classified as residential.

Detailed analysis is linked below:

Energy Savings Analysis: ANSI/ASHRAE/IES Standard 90.1-2019 (64 pages)

Upon publication of this affirmative determination, each State is required by statute to certify that it has reviewed the provisions of its residential building code regarding energy efficiency, and made a determination as to whether to update its code to meet or exceed the 2018 IECC. Additionally, this notice provides guidance on state code review processes and associated certifications.

Public consultation closes December 10, 2021

We maintain this topic on our periodic Energy and E Pluribus Unum (State) colloquia.   See our CALENDAR for the next online meeting; open to everyone.
