Gated Communities In The Uae: From A Social Sustainability Barrier To A Catalyst, Marwa Salem Al Jaberi
Theses
Gated communities are commonly defined as residential areas with restricted access, where commonly public spaces are privatized. The main characteristic of gated communities, based on the physical aspect of the development, involves gates, walls, guards, and closed-circuit surveillance. Scholarly studies have focused on the phenomenon of gated communities through covering its implications on the society and the city, where the benefits of this type of development have been frequently questioned. Gated communities have been linked with their negative impacts on the communities as socially segregated areas form the surrounding urban context. Nonetheless, several other studies advocated paradoxical theories related to …

With the emerging of new technologies, the look for more sustainable towers appears. Through designing twisted towers, an aerodynamic and energy efficient structure can be made to reduce materials and wind loads towards it. By definition, a twisted building is one that has gradually rotating floor plates along its height. The problem here rises due to the risk of structural failure and lack of load transfer and unorganized interior function. Thus, this research aims to detect the design solutions used to execute the twisted buildings achieving stability, safety, and withstanding climatic effects. In order to accomplish the mentioned aim, the …

This paper presents an energy-efficient classification framework that performs human activity recognition (HAR). Typically, HAR classification tasks require a computational platform that includes a processor and memory along with sensors and their interfaces, all of which consume significant power. The presented framework employs microelectromechanical systems (MEMS) based Continuous Time Recurrent Neural Network (CTRNN) to performHAR tasks very efficiently. In a real physical implementation, we show that the MEMS-CTRNN nodes can perform computing while consuming power on a nano-watts scale compared to the micro-watts state-of-the-art hardware. We also confirm that this huge power reduction doesn’t come at the expense of reduced …

Framework To Develop Time- And Voltage-Dependent Building Load Profiles Using Polynomial Load Models, Andrew Parker, Mhd Anas Alkrch, Kevin James, Ahmad Almaghrebi, Mahmoud Alahmad
Durham School of Architectural Engineering and Construction: Faculty Publications
The power consumption of buildings over the course of each minute, hour, day and season plays a major role in how this load influences the Electric Power System voltage and frequency, and vice versa. This consumption is based on the building's load component types, efficiencies, and how they consume power and react to changes in real time. Due to this complexity, standard full-building load models are typically voltage-invariant. This paper proposes a novel framework to transform these voltage-invariant building load models into fully time- and voltage-dependent load profiles using available data on the voltage sensitivity of individual load components. While …
