Buffering Pv Output During Cloud Transients With Energy Storage, Yacouba Moumouni
Buffering Pv Output During Cloud Transients With Energy Storage, Yacouba Moumouni
College of Engineering: Graduate Celebration Programs
The Problem
• Photovoltaic output power can be affected by many factors including clouds passing overhead.
• Utilities in generally prefer a guaranteed power delivery level over some specified power delivery period.
• Power delivered during peak demand hours is generally more valued by utilities. For the Desert Southwest this is in the summertime afternoons. For the local area this will be defined as 1-5 pm for the three summer months.
• While battery power can be adapted to this problem, large batteries to be expensive.

Natural structure with simultaneous negative permittivity and permeability has not been discovered yet. However, using specially-designed metal embedded in dielectric bodies can achieve a kind of artificial negative index. This periodic structure which is smaller than the guided wavelength is known as a metamaterial. However, recent designs of metamaterials have some disadvantages when they are used in the application of solar cell. The perfect absorption is only within a narrow band, and for most of the solar spectrum, the absorption is no more than 10%. Here, a new kind of absorber for the solar spectrum has been designed and analyzed, …

INTRODUCTION
Manual Counters:
•The vehicles counts and characteristics at signalized intersections and others transportation facilities are usually made using manual counters. These manual counters are mechanical or digital boards in which the user can record the different observations from the field. The use of these devices is usually required when more sophisticated methods are not available, when expensive equipment is not justified and for scholastic practices.

Real-Time Face Detection And Recognition, Parker Hill, Brendan Morris
College of Engineering: Graduate Celebration Programs
The face has become a popular biometric for identification due to the wide range of features and difficulty in manipulation of the metric. In order to work towards a robust facial recognition system, this work contains a foundation for using the face as a recognition metric. First, faces are detected from still images using a Viola-Jones object detection algorithm. Then, Eigenfaces is applied to the detected faces. The system was tested on face databases as well as real-time feed from a web camera.
Modeling Passive Solar Distillation In Las Vegas, Nv, Noe I. Santos
Modeling Passive Solar Distillation In Las Vegas, Nv, Noe I. Santos
College of Engineering: Graduate Celebration Programs
Project Background
• Many rural areas on the planet do not have easy access to clean water!
• Water distillation basins are capable of distilling water by using incident solar radiation to evaporate polluted water.
• Current thermodynamic models used to predict behavior require instantaneous data; requires the use of expensive equipment.
• Distillation basins are dependent on multiple meteorological variables: insolation, temperature, wind speed, cloud cover.
• Non‐linear behavior is difficult to predict for long term operations.

Framework Developmant For Construction Safety Visialization, Kishor Shrestha
College of Engineering: Graduate Celebration Programs
Throughout the history of the construction industry, many fatalities and injuries have occurred in construction sites. One of the major causes of accidents is unsafe site conditions: basically, this is due to inadequate supervision. To improve upon the traditional supervision approach, this study proposes a 'Framework Development for Construction Safety Visualization' approach. In addition to this, a computer vision Edge Detection Algorithm was developed and tested to convert construction site still images into edges of the objects in the images. The framework development of this study uses computer vision, robot vision, image compression, pattern recognition, internet transmission, network communication, and …
Impact Of Sludge Treatment Processes On Estrogen Concentration In Wastewater Sludge, Erica Marti
Impact Of Sludge Treatment Processes On Estrogen Concentration In Wastewater Sludge, Erica Marti
College of Engineering: Graduate Celebration Programs
Endocrine-disrupting compounds (EDCs), such as estrogen, are known to be present in the aquatic environment at concentrations that affect fish and other wildlife. For example, juvenile male fish exposed to estrogen will synthesize vitellogenin, which is a female-specific protein. Estrogen exposure is also linked to sex reversal, intersexuality, and inhibition of gonadal growth (Jobling et al., 1996).
Wastewater treatment plants are major contributors of EDCs into the environment. EDCs end up in wastewater as a result of natural excretion from the body or being washed off the skin. WWTPs are not designed to remove these substances. As a result, EDCs …
