In the article “IoT based Smart Parking Systems for Smart Cities”, hIOTron (2020) claims that smart parking technology will improve the overall efficiency on roads and the experience of users. Smart parking utilizes sensors installed on lots to detect lot availability, which can be used in offices and shopping malls. Occupants can book in advance the desired lot while receiving real-time accessibility. Once the sensors confirm a vacant lot, the car will be parked automatically. An IoT solution must make it easy to transfer field data to the cloud at low cost and increased return of investment (ROI). Challenges faced include real upfront costs, as in-ground sensors can incur the additional cost of two parking systems. The sensors may read data from the other parking systems and add them to the user’s lot. Smart parking authentication is done using an  RFID  tag and data collected is reserved in the cloud. The app would find a vacant lot and send the location to the user after r...

The Sydney Morning Herald. (2017). What is cladding and why is it used on buildings?. https://www.smh.com.au/national/what-is-cladding-and-why-it-is-used-on-buildings-20170615-gwrir6.html In this article, Herald (2017) focus on what is cladding and its usage. The article states that cladding is an extra layer on the exterior of a building. Cladding can be attached to the building’s structure or act as an intermediate layer of spacers. The main purpose of cladding is to stop wind and rain from entering the building. Cladding also provides sound and thermal insulation as well as fire resistance. Cladding is made up of many different materials, however, each material is different in terms of their resistance to fire. Brick cladding is excellent in fire resistance while weatherboards cladding made from steel are high in fire resistance. Aluminum cladding is good in fire resistance while plywood sheet cladding is poor in fire resistance. The panel consists of two aluminum faces and a cor...
