FAULT DIAGNOSIS OF ELECTRONIC FUEL CONTROL (EFC) VALVES VIA DYNAMIC PERFORMANCE TEST METHOD
Electronic Fuel Control (EFC) valve regulates fuel flow to the injector fuel supply line in the Cummins Pressure Time (PT) fuel system. The EFC system controls the fuel flow by means of a variable orifice that is electrically actuated. The supplier of the EFC valves inspects all parts before they …

Selective recovery of salts from a ternary eutectic system in EFC using seeding
… research within Eutectic Freeze Crystallization (EFC) has focused on the crystallization of ice and single salts from aqueous solutions. However, as a single salt and ice are crystallized, the concentration of the non-crystallizing salt species increase until the system is saturated with more than …

Accelerating Embedded HOWFSC Algorithms
… optical modeling and Electric Field Conjugation (EFC). Optical modeling underpins both Jacobian-based EFC, and a relatively new variant of EFC, called adjoint-based EFC. The two main contributions of this thesis are to port bottleneck HOWFSC algorithms to the relevant computing environments, and …

Effect of antiscalants during eutectic freeze crystallization of a reverse osmosis retentate
Eutectic Freeze Crystallization (EFC) is a separation technique which involves simultaneous crystallization of water and solute under eutectic conditions. It can be applied to treatment of various industrial aqueous streams containing dissolved organic and inorganic contaminants, such as reverse …

PROGRAM PARTICIPATION AND EXPERIENCES IN YOUNG ADULTS CURRENTLY OR FORMERLY RECEIVING FOSTER CARE SERVICES
… whether participation in Extended Foster Care (EFC) or the Aftercare Program increase perceptions of independence in former and current foster dependents ages eighteen and older. Foster youth have historically experienced worse outcomes than the general population after reaching age 18. This …

KNOWLEDGE AND USE OF FAMILY PLANNING SERVICES BY EXTENDED FOSTER CARE CLIENTS
… of this research, Extended Foster Care (EFC) was created to help to provide additional resources and support to young adults in foster care until age 21. This is a fairly new program, therefore little research has been completed. One of the negative outcomes of foster youth is the high …

Extended Foster Care: The General Population's Perspective
… perspective towards extended foster care (EFC) and emerging adulthood. Topics varied from when foster youth should emancipate to when emerging adult children should move out of their parents’ homes. There is very little literature regarding the topic of EFC, which could impact the …

Gypsum seeding to prevent scale formation and improve separation efficiency
Eutectic freeze crystallization (EFC) is a novel separation technique that can be applied to treat brine solutions such as reverse osmosis retentates. These are often a mixture of different inorganic solutes. The treatment of calcium sulphate-rich brines using EFC often results in gypsum …

AN EXAMINATION OF STUDENT FINANCIAL SECURITY AND STUDENT PERSISTENCE DECISION-MAKING IN COLLEGE
… over and above expected family contribution (EFC) and grade point average (GPA), data on these variables were collected from students at Mid-Atlantic University between the years of 2017 and 2019. Each variable was run separately at the univariate level through correlations (or chi square for …

The Effectiveness of Extended Foster Care in Preparing Young Adults for Self-Sufficiency
… the effectiveness of the Extended Foster Care (EFC) Program in meeting the needs of emancipating foster youth by assisting them in becoming self-sufficient prior to emancipating out of the foster care system. The research method used for this study was a quantitative study design, using …

Alternative methods of vertical plasma control in the Alcator C-Mod Tokamak
… a pair of outboard equilibrium field coils (EFC). The first part of this investigation examines the possibility of using inboard ohmic heating coils (OH2) as the controlling coils. A coupling transformer was designed to connect a large amperage/low bandwidth power supply to a small …

Investigating the Effect of Heat Transfer Driving Force and Seed Loading on the Batch Eutectic Freeze Crystallization of a Dilute Brine
Eutectic Freeze Crystallization (EFC) is a separation technology that separates solute from solvent. It is often used as a wastewater treatment process for industrial brines. In EFC, the solution is cooled to temperatures below the eutectic point of the brine, such that ice and salt simultaneously …

Uncertainty quantification for pavement life-cycle stages
… to assess the vehicle excess fuel consumption (EFC) due to pavement deflection. The developed relationship relies on the fundamental energy-deformation principles obtained by conducting nonlinear regression analysis on 3-D finite element (FE) simulations. The proposed model is formulated using a …

Development of mechanistic rolling resistance model for pavement life cycle assessment
… capture the impact of excess fuel consumption (EFC) and dynamic wheel load (DWL) caused by pavement roughness. The study begins with the development of regional life cycle impact assessment (LCIA) databases and models for Illinois. The LCIA databases were regionalized based on inventory data …

Development of a brine treatment protocol using Eutectic Freeze Crystallization
… treatment...This thesis ultimately showed that EFC could be used to treat multi-component streams and that pure salts could be sequentially produced along with potable water.

Development of novel fertilizer manufacturing processes using human urine
… step. In Paper 5, eutectic freeze concentration (EFC) was investigated to further concentrate the RO brine (70% water removal), whilst simultaneously crystallizing undesirable salts, as this treatment method is not affected by membrane scaling. It was experimentally shown that at eutectic …

Increasing Life Skills While Decreasing Depression, Anxiety, and Stress in Transitional Aged Youth: A Person-Centered Mentorship Approach
… now a part of the Extended Foster Care system (EFC). Unfortunately, this population is not guaranteed familial or social support. They have to rely on basic knowledge and skills obtained while in the foster care system to help with navigate their world. Most TAYs end up homeless, unemployed, and …

Ice scaling in continuous eutectic freeze crystallization
Eutectic Freeze Crystallization (EFC) is a novel and potentially cost effective technique to treat industrial brines by the simultaneous crystallization of ice and salt under sub-eutectic conditions. Previous research has demonstrated that the formation of an ice scale layer on the cooling surfaces …

Impurities in crystals formed by eutectic freeze crystallization
… waste brines; Eutectic Freeze Crystallization (EFC), can potentially separate these into pure water and its major constituent salts, which can be reused or sold. The feasibility of this technology is heavily invested in its capacity to produce pure salts. Thus, it is important to investigate the …
