Patterns of electricity generation and consumption in the United States have rapidly changed over the past decade and are forecasted to continue doing so in coming decades. On the supply side, increasing generation from renewable sources has raised concerns about the ability of the electrical grid to stay stable given renewables’ intermittent and distributed nature, and has increased calls for n ...

THE PURPOSE OFTHIS RESEARCH EFFORT IS TO DETERMINE THE FEASIBILITY OF USING BILINGUAL TEXT ANALYSIS SOFTWARE AS A TOOL TO ASSIST IN TEACHING ENGLISH WRITING SKILLS TO NON -NATIVE SPEAKERS. SINCE SPANISH IS THE VATIVE LANGUAGE PREDOMINANTLY SPOKEN BY STUDENTS ENROLLED IN BILINGUAL PRL PROGRAMS IN GRADES 1-12 IN THE SAN DIEGO AREA, IT HAS BEEN SELECTED AS THE TARGET LANGUAGE IN PHASE I. THIS EFFORT ...

THE PRESENCE OF SOLID PARTICULATES ENTRAINED IN THE AIR CAN BE DETECTED BY MEASURING THEIR SCATTERED LIGHT AND THE OV OVERALL LIGHT EXTINCTION. VERY SENSITIVE EXTINCTION M MEASUREMENTS CAN BE PERFORMED WITH TRANSMISSOMETRY. AM AMONGTHE MOST PROMISING AND SIMPLE TRANSMISSOMETERS ARE THE MA MAXIMUM TURBIDITY METHOD, DISPERSION QUOTIENT METHOD, AND THE TWO-COLOR TRANSMISSOMETER. FOR REASONABLY CLEAN ...

Concentrator PV systems using highly efficient multijunction photovoltaic cells hold out the promise of very low-cost solar electricity generation, but their adoption has been hamstrung by the requirement for bulky mechanical trackers that add cost, diminish land use, increase maintenance, and exclude roof-top installations. The Stationary Wide-Angle Concentrator (SWAC) PV system will provides the ...

Through a prior project, Sokikom developed a suite of games to replace or supplement Grade school math topics. In this project, the team will develop and test a prototype of Sokikom for Teachers (S4), a platform to host the math games for teacher-led direct instruction for Grade 4 math standards. S4 will include "just-in-time" prompts to support teacher-guided mathematical conversations with stude ...

The U.S. Environmental Protection Agency (EPA) Office of Water (OW) is seeking innovative technologies to improve the performance and reliability of small drinking water systems. In response, Physical Optics Corporation (POC) proposes to develop a novel Regenerative Capacitive Electro-Desalination System (RECED) to enable the use of reduced-quality water sources, such as weakly saline brackish wat ...

OPERATING STRATEGIES HAVE BEEN DEVELOPED FOR BIOLOGICAL SEQUENCING BATCH REACTOR (SBR) TREATMENT OF BOTH MUNICIPAL WWASTE (I.E. LOW-STRENGTH WASTES) AND INDUSTRIAL WASTES (I.E.HIGH-STRENGTH WASTES CONTAINING DIFFICULT TO DEGRADE ORGANICS). SBR SYSTEMS SHOULD ALSO OFFER ADVANTAGES FOR BIOLOGICAL TREATMENT OF MIXED MUNCIPAL AND INDUSTRIAL WASTEWATERS THAT ARE RELATIVELY LOW STRENGTH, BUT CONTAIN INO ...

Toxic air pollutants, also known as hazardous air pollutants (HAPs), are those pollutants that are known or suspected to cause cancer or other serious health effects, such as reproductive effects or birth defects, or adverse environmental effects. In today's environment, there are continuing problems associated with the environmental effects of multiple pollutant gas released to the air. This conc ...

In prior research and development, the team developed WuzzitTrouble, an iPhone and iPad gaming app where players solve problems using number sense mathematical strategies. This project will develop and test a prototype of an adaptive engine for this game, intended to tailor gameplay to the skill levels of individual students and to provide support (or scaffold learning) for students with weaker sk ...
