Pedestrian bollards protect walkways from vehicle intrusion, guide foot traffic, snow plows and can provide heating and illumination. They should be positioned in front of energy utility services (such as natural gas and electrical power switchgear). at sidewalk entrances, crosswalks, and near pedestrian-heavy zones. Join us today at 16:00 UTC when we examine best practice literature and a few construction details as time allows.

From time to time we break from our interest in lowering the cost of our “cities-within-cities” to enjoy the work of our colleagues responsible for seasonal ambience and public art. We have a dedicated post that celebrates the accomplishments of our gardeners and horticultural staff. Today we dedicate a post to campus fountains–a focal point for gathering and a place for personal reflection for which there is no price.
Alas, we find a quickening of standards developing organizations growing their footprint in the spaces around buildings now. They used to confine the scopes of their standardization enterprises to the building envelope. That day will soon be behind us as an energized cadre of water rights social justice workers, public safety, sustainability and energy conservation professionals descend upon campus fountains with prescriptive requirements for evaporation rates, bromine concentrations, training, certification and inspections. In other words regulators and conformity functionaries will outnumber benefactors and fountain designers 1 million to 1.
We will deal with all that when the day comes. For the moment, let’s just enjoy them.
We are happy to walk you through the relevant structural, water safety, plumbing and electrical issues any day at 11 AM EST during our daily standing online teleconferences. Click on any image for author attribution, photo credit or other information.

Speech Day generally refers to an annual event held at schools in the United Kingdom, particularly private or independent schools, where students showcase their achievements and receive prizes or awards. The exact date of “Speech Day” varies by school and is typically determined by the school’s academic calendar. It is usually held towards the end of the academic year, either in the summer term or in the early autumn term, before students break for the summer holidays.
Abstract: Internet of Things (IoT) is the interconnection of physical objects and devices to the internet and in turn to each other to aid decision making. This paper deals with automation of gardening systems using IoT. With water resources becoming ever so scarce by the day, it has become imperative that we use water extremely judiciously in all walks of our daily life. We track the environmental conditions such as humidity of the soil, and temperature and take an appropriate route towards the problem. Based on the data collected, we run algorithms which help keep the garden in good condition and at the same time using resources optimally.
