The Progression of LGBTQ+ Acceptance in K-12 Schools in the United States: A Critical Literature Review

Previous research addressing phobia toward K-12 students in the LGBTQ+ community considers mental, emotional, physical, and spiritual effects. Students in the community have experienced progress in the past 20 years regarding equality, support, and empowerment from institutions, interpersonal relationships, and insecurities within themselves. In this study, I review several academic articles and textbooks which highlight the progress students have experienced regarding prejudice and backlash in K-12 schools in the United States. These sources specifically consider the well-being of youth who identify as Lesbian, Gay, Bisexual, Transgender, Queer, and more. My research shows where we were 20 years ago, where we are now, and offers suggestions to implement in schools to better support LGBTQ+ students moving forward

Estimation of Wind Velocity on Flexible Unmanned Aerial Vehicle Without Aircraft Parameters

This research project estimated the wind velocity of a small flexible-wing Unmanned Aerial Vehicle using a software developed the analysis of the data collected by airspeed and attitude sensors. The purpose of this paper is to contribute to the extensive research of destructive vibrations on flexible wing aircraft. The estimation of the wind velocity will be implemented as part of the control design project. This paper is based on literature review of the estimation of wind velocity using only kinematic relationships with a Kalman Filter. The testbed used for wind estimation was a Volantex Ranger EX 757-3. Experimental data of velocity, altitude, and attitude were obtained by performing circular maneuvers at Daytona Beach Radio Control Association. After sampling and processing all the data, the computer code returns the wind velocity estimation of a North-East-Down frame and the airspeed sensor calibration factor. Results show a valid estimation when compared with the local weather data of the date of flight and the sensor calibration factor within typical range. This method of wind velocity estimation is proven to be valid and will yield to the estimation of the incident angles using aerodynamic forces relationships

Simulation of an absorption based solar cooling facility using a geothermal sink for heat rejection

An important issue of solar cooling facilities based on absorption cycles and sometimes not given the necessary attention is the recooling process of the absorber and condenser. This is critical in the overall behaviour of the facility because the condensation and absorption temperatures will affect the COP and cooling capacity of the chiller. Most of the time the recooling process is made by using a wet cooling tower in a closed loop through the absorber and condenser. The use of a wet cooling tower gives good results in terms of cooling capacity and COP, but presents some health risk, like legionella, and its use is restricted to the industrial sector and places where water scarcity is not present. This paper presents the modification of the already validated TRNSYS simulation of a solar cooling facility, implementing a geothermal heat sink instead of the wet cooling tower in order to dissipate the heat generated internally in the absorption chiller. Simulation results shows that a geothermal heat sink composed of 6 boreholes of 100 meters of depth should be sufficient in order to substitute the wet cooling tower, for a typical Spanish single family dwelling.Universidad Carlos III de Madrid - ITEA Research GroupPublicad

Experimental analysis of thermal storage tank configurationin a solar cooling installation with an absorption chiller

The use of air conditioning systems in Spanish dwellings is gaining popularity, as the installed units grows by 0,8 million per year. The most popular air conditioning system today is the vapor-compression cycle. This kind of system consumes a considerable amount of electric energy as it incorporates a mechanical compressor in its cycle and utilizes refrigerants that can be dangerous to the environment. A solution to this kind of equipment can be found in Solar Facilities configured to produce cold water for air conditioning purposes by means of an absorption chiller. This kind of equipment can be driven by a heat input produced by the solar facility. This machine consumes a very low amount of electric energy and presents great advantages for the environment. Nevertheless, the need of a heat reservoir to operate in the afternoon hours, where solar radiation is not enough to drive the chiller, is indispensable in a solar facility. To serve this purpose, the introduction of a thermal storage tank has to be made. There are two basic internal configurations of a thermal storage tank in a solar cooling facility. These are Stratification and Well-mixed configuration. Experimental results show that for solar cooling applications, having a homogeneous mixture temperature in the thermal storage tank produce more daily cooling energy than in an stratified one, although the solar field efficiency is lower. This gives the facility more autonomy of operation in the afternoon, when the sun goes down and radiation is not enough for the application. Effects on the facility produced by Well-mixed configuration are: efficiency reduction on the solar collector’s field , 0,27, higher daily COP’s, 0,33, and extended solar cooling time of about two hours.Universidad Carlos III de Madrid - ITEA Research GroupPublicad
