Automated demand response can be a valuable resource for ancillary services in the power grid. This paper illustrates this value with the first experimental demonstration of frequency regulation from commercial building Heating Ventilation and Air Conditioning (HVAC) systems. The experiments were conducted in a 40,000 sq. ft. commercial building located at the University of Florida campus. Deta...

As more and more critical services are provided over the Internet, the risk to these services from malicious users is also increasing. Several networks have witnessed Denial of Service (DoS) attacks over the recent past. This paper reports on our experience in building a Linux-based prototype to mitigate the effect of such attacks. Our prototype provides an efficient way to keep track of server...

In the mining industry, at the beginning of development of a project, a consultant is assigned to build a design feasibility study to incorporate the client requirement, government regulation, and other inputs into the design. The consultant usually faces overwhelmed stages due to changes caused by the client and other stakeholders and has to repeat the process of inputting requirements into th...

Building a nervous system requires a precise sequence of genetic transitions, mediated in part by the temporal and spatial regulation of transcription factors. Quan et al. add to our understanding of this regulation by describing an evolutionarily conserved post-translational mechanism that rapidly extinguishes proneural protein activity in neural precursors.

Left ventricular hypertrophy (LVH) is a common adaptive response of the heart to the increased workload associated with hypertension.1 Essential hypertension is characterized by an increase in total peripheral resistance.2 Mechanical modeling of the cardiovascular system suggests that a necessary consequence of increased downstream resistance to flow is increased pressure to maintain end organ ...

The results of building evaluation and feed back have been used for centuries, particularly following a major building failure. These evaluations have resulted in regulations that historically have often been the only systematic and research-based source of direction to building design. Regulations evolved into building codes, which began to control critical aspects of buildings. Over the years...

In this paper, we model energy use in commercial buildings using empirical data captured through sMAP, a campus building data portal at UC Berkeley. We conduct at-scale experiments in a newly constructed building on campus. By modulating the supply duct static pressure (SDSP) for the main supply air duct, we induce a response on the main supply fan and determine how much ancillary power flexibi...
