AS SUBCONTRACTOR TO OSU, RAYTHEON TECHNOLOGIES RESEARCH CENTER (RTRC) WILL CONTRIBUTE TO THE THERMAL DESIGN OF THE PROTOTYPE, SUPPORT CONTROL STRATEGY DEVELOPMENTS FOR THE PROPOSED DC ENERGY ROUTER, SUPPORT CIRCUIT DESIGN BY PROVIDING SUGGESTIONS ON DESIGN PARAMETERS AND PERFORM TECHNOLOGY TO MARKET ACTIVITIES BY INTRODUCING THE PROJECT TO RTRC BUSINESS UNITS.

THERE ARE TWO GOALS OF THIS PROJECT: 1. TRANSFORM THE MODELING OF ORBITAL MECHANICS BY AUGMENTING PHYSICS-BASED DYNAMICS WITH EXPLAINABLE DATA-DRIVEN TECHNIQUES. THE RESULTING PHYSICS/DATA “HYBRID MODELS” WILL BE INTEGRATED WITH THE FOLLOWING APPLICATIONS: (A) KEY FUNCTIONS IN THE SPACE-DOMAIN AWARENESS (SDA) KILL CHAIN (FIG.(1)), INCLUDING DETECTION, INITIAL ORBIT DETERMINATION AND ORBIT DETERMINATION, DATA-ASSOCIATION, MAINTAINING OBJECT CUSTODY, AND INTENT ESTIMATION. (B) HIGH FIDELITY MODEL DEVELOPMENT FOR THE XGEO AND CISLUNAR DOMAINS TO ADDRESS THE DUAL CHALLENGE OF HIGH NONLINEARITY AND LONG PROPAGATION TIMES IN THESE REGIMES. 2. EXTEND THE OUTCOMES OF DATA-AUGMENTED MODELING IN ORBIT TO ANSWER FUNDAMENTAL QUESTIONS RELATED TO THE THEORY OF NONLINEAR SYSTEM IDENTIFICATION. FIGURE

SCIENCE PERSONNEL: PI DR. FEDERICO FRASCHETTI IS RESPONSIBLE FOR LEADING AND MANAGING THE OVERALL EFFORT. DR. FRASCHETTI WILL PROVIDE THE MHD MODELING FRAMEWORK AND THE ROUTINES TO CALCULATE A MHDSCALE TURBULENCE WITHIN MAGNETIC FLUX TUBES TO INVESTIGATE THE GCR TRANSPORT AT THE BOUNDARY BETWEEN FLUX TUBES AND CLOSED MAGNETIC ARCADES IN THE LOW CHROMOSPHERE, WILL ASSIST WITH THE INTERPRETATION OF THE RESULTS AND THE PREPARATION OF THE REFEREED PUBLICATIONS. CO-I DR. MAHBOUBEH ASGARI-TARGHI WILL DEVELOP A MODEL THAT DESCRIBES THE HEATING OF CORONAL LOOP PLASMA BY MAGNETOHYDRODYNAMIC (MHD) TURBULENCE. THE REDUCED RMHD MODEL IS BASED ON THE COUNTER-PROPAGATING INTERACTION OF ALFVEN WAVES GENERATED AT THE PHOTOSPHERIC FOOTPOINTS. THE CO-I WILL ALSO WRITE THE DESCRIPTIONS OF THE MODELING RESULTS FOR SUBMISSION TO PEER-REVIEWED JOURNALS. DR. FRASCHETTI HAS 1 MONTH PER YEAR ALLOCATED FOR ALL THREE YEARS. DR. ASGARI-TARGHI ALSO HAS 1 MONTH PER YEAR PLANNED. OTHER PERSONNEL: THE BUDGET ALSO INCLUDES 40 HOURS PER YEAR FOR A FUND MANAGER FOR GRANT SPECIFIC ADMINISTRATIVE SERVICES. THESE EFFORTS ARE NOT RECOVERED AS INDIRECT COSTS, AND INCLUDE TRACKING AND MONITORING EXPENDITURES, PROCESSING TRAVEL AUTHORIZATIONS, AND PREPARING REQUISITIONS FOR PURCHASES. THE FUND MANAGER WILL ALSO ASSIST THE PI AND CO-I, IF NECESSARY, WITH TIMELY SUBMISSION OF PROGRESS REPORTS, AND ENSURING COMPLIANCE WITH APPLICABLE FEDERAL REGULATIONS. TRAVEL: WE INCLUDE A TRAVEL BUDGET FOR THE PI TO ATTEND THE AAS WINTER MEETING EACH YEAR TO PRESENT SCIENTIFIC RESULTS. THE DESTINATION OF FIRST YEAR CONFERENCE IS NATIONAL HARBOR, MD WITH COST OF: PER DIEM $1,445 ($289/DAY FOR 5 DAYS) + $265 AIRFARE + MISCELLANEOUS OF $1,274 = $2,984 TOTAL ESTIMATED COST. MISCELLANEOUS COSTS EACH YEAR FOR AGU CONFERENCES IS CALCULATED AS FOLLOWS: $899/PERSON REGISTRATION FEE + $75/DAY FOR 5 DAYS FOR GROUND TRANSPORTATION AND BAGGAGE FEES = TOTAL MISCELLANEOUS OF $1,274. YEAR 2 AAS IS PLANNED IN PHOENIX, AZ WITH COST OF: PER DIEM $2,485 ($497/DAY FOR 5 DAYS) + $239 AIRFARE + MISCELLANEOUS OF $1,274 = $3,998 TOTAL ESTIMATED COST. YEAR 3 AAS IS PLANNED IN SALT LAKE CITY, UT WITH COST OF: PER DIEM $1,110 ($222/DAY FOR 5 DAYS) + $560 AIRFARE + MISCELLANEOUS OF $1,274 = $2,944. PER DIEM AND AIRFARE COSTS ARE INFLATED BY 3% EACH YEAR.

SENIOR PERSONNEL OFER COHEN, PHD, PRINCIPAL INVESTIGATOR WILL RECEIVE 0.50 SUMMER MONTHS SUPPORT FOR EACH YEAR OF THE PROJECT. THE YEAR 1 ANNUAL SALARY IS $122,354.06. DR. COHEN IS AN ASSOCIATE PROFESSOR OF PHYSICS AT THE UNIVERSITY OF MASSACHUSETTS LOWELL AND WILL BE RESPONSIBLE FOR THE OVERALL COORDINATION OF THE PROJECT AND SUPERVISION OF THE PROJECT PERSONNEL. THE PI WILL PROVIDE SOLUTIONS FROM THE SWMF NEEDED TO CALCULATE GAMMA-RAY PRODUCTION. FRINGE BENEFITS FRINGE BENEFITS INCLUDED IN THE ESTIMATES FOR PERSONNEL WERE CALCULATED IN ACCORDANCE WITH THE UNIVERSITY OF MASSACHUSETTS LOWELL RATE AGREEMENT NEGOTIATED WITH THE DEPARTMENT OF HEALTH AND HUMAN SERVICES ON NOVEMBER 8, 2023. FRINGE RATES ARE CALCULATED AS FOLLOWS: 2.11% FOR PI SUMMER SUPPORT INDIRECT COSTS THE UNIVERSITY OF MASSACHUSETTS LOWELL'S (UML) FEDERALLY NEGOTIATED INDIRECT COST RATE FOR ORGANIZED RESEARCH IS CURRENTLY 56.5% OF MODIFIED TOTAL DIRECT COSTS. MODIFIED TOTAL DIRECT COSTS TOTALS $21,667 AND EXCLUDES EQUIPMENT, CAPITAL EXPENDITURES, CHARGES FOR PATIENT CARE, RENTAL COSTS, TUITION REMISSION, SCHOLARSHIPS AND FELLOWSHIPS, PARTICIPANT SUPPORT COSTS AND THE PORTION OF EACH SUBCONTRACT IN EXCESS OF $25,000. COGNIZANT AGENCY: DEPARTMENT OF HEALTH AND HUMAN SERVICES (DHHS) DIVISION OF COST ALLOCATION 26 FEDERAL PLAZA, ROOM 41-122 NEW YORK, NY 10278 CONTACT: RYAN MCCARTHY, (212)264-2069, RYAN.MCCARTHY@PSC.GOV TOTAL ESTIMATED COSTS $33,909

FLIGHT RECEIVERS FOR ORBITAL REMOTE SENSING OF BURIED LUNAR ICE DEPOSITS VIA CORALS: THE COSMIC RAY LUNAR SOUNDER

OBJECTIVE IS DESIGNING, FABRICATING, AND TESTING LOW-PROFILE ULTRA-WIDEBAND (300 MHZ- 60000MHZ) ANTENNA PROTOTYPES FOR SUPPORTING THE OPERATION OF THE PROPOSED LUNAR HEAT FLOW RADIOMETER SYSTEM.

CO-I MARSHALL JOHNSON WILL CONDUCT THE DOPPLER TOMOGRAPHIC ANALYSIS, AS WELL AS THE LBT HIGH-RESOLUTION IMAGING OBSERVATIONS OF OUR TARGET STARS, SOME OF THE ROSSITER-MCLAUGHLIN AND RV ANALYSIS, AND ADVISE TWO UNDERGRADUATE STUDENTS. DR. JOHNSON WILL USE OUR TRANSIT OBSERVATIONS OF SUFFICIENTLY RAPIDLY ROTATING HOST STARS TO PERFORM DOPPLER TOMOGRAPHIC ANALYSES. HE WILL EXTRACT THE TIME SERIES ABSORPTION LINE PROFILES FROM THE SPECTRA, AND MODEL THE DATA TO EXTRACT THE SKY-PROJECTED SPIN-ORBIT MISALIGNMENTS FOR THESE PLANETS. ALL OF THE SOFTWARE TOOLS NECESSARY TO CONDUCT THIS WORK ALREADY EXIST. HE WILL ALSO PROPOSE FOR LBT TIME TO OBTAIN HIGH-RESOLUTION IMAGING OF OUR TARGET STARS, HELP CONDUCT THE OBSERVATIONS AS PART OF THE OSU LBT QUEUE, AND REDUCE AND ANALYZE THE DATA. HE WILL ALSO ASSIST WITH MODELING THE LONG-TERM RVS, AND WILL ALSO SUPERVISE THE TWO UNDERGRADUATE STUDENTS WHO WILL BUILD TOOLS AND TUTORIALS AND ANALYZE DATA FOR THIS PROJECT. DR. JOHNSON HAS CONSIDERABLE EXPERTISE TO PERFORM THESE TASKS, HAVING SPENT MORE THAN A DECADE PERFORMING DOPPLER TOMOGRAPHIC OBSERVATIONS AND ANALYSIS. HE IS ONE OF THE WORLD"S EXPERTS IN THIS TECHNIQUE. HE ALSO HAS SEVERAL YEARS OF EXPERIENCE WITH ANALYZING RV TIME-SERIES DATA, AND WITH OBSERVATIONS WITH THE LBT.
