Electrokinetic deposition of methylmethacrylate is used to mitigate

corrosion in reinforced concrete. The methylmethacrylate (MMA)

monomer deposits in the pores in the concrete where it is converted into

its polymer, polymethylmethacrylate, thus creating a barrier that also

enhances the mechanical properties of the concrete. Previous to the MMA

treatment, an electrokinetic deposition is used to transport calcium,

sodium and potassium hydroxide particles through the capillary pores of

concrete directly to the concrete reinforcement. The intent is to use these

compounds as a sacrificial electrode layer during the electrokinetic

deposition of methylmethacrylate monomer. Cylindrical reinforced

concrete specimens were subjected to electrokinetic treatment and the

specimens were tested to characterize porosity reduction and tensile

splitting strength, showing an increase in the tensile strength. In addition,

nine specimens treated electrokinetically and in long-term atmospheric

exposure testing at NASAs Kennedy Space Centers seaside atmospheric

exposure test site were tested to determine their corrosion rate.

The Neutron Star Interior Composition ExploreR (NICER) will be a NASA Explorer Mission of

Opportunity, dedicated to the study of neutron stars, the only places in the universe

where all four fundamental forces of nature are simultaneously important. Answering the

long-standing astrophysics question How big is a neutron star?, NICER will confront

nuclear physics theory with unique observation constraints, exploring the exotic states of

matter within neutron stars, and revealing their interior and surface compositions through

rotation-resolved X-ray spectroscopy. NICER will feature 56 co-aligned X-ray concentrators

and matching detectors with a 2,000 cm2 effective area. Each optic is roughly 6 inches in

height and 4 inches in diameter, featuring 24 concentric aluminum foils which are

individually coated with gold. The detectors which are , located at the focal length of 1.085

meters behind the optics, each have a 2mm aperture. NICER will be the first X-Ray

telescope utilizing mirrors in a full cylindrical configuration, along with new

manufacturing techniques on such a small scale. We began characterizing the

effectiveness of the first assembled optics or engineering testing units (ETUs) bydetermining the point-spread function. The optics were placed inside a vacuum, where

they received approximately parallel X-ray photons. The data is then picked up by the

detector and analyzed with software. We find a 1.84 mm half-flux radius and a 3.49 mm

80% flux radius for the fully populated optic, and a 0.72 mm half-flux radius and a 1.64 mm

80 % flux radius for the sparsely populated optic. From these results we conclude that the

optics are performing relatively well, and should meet design requirements with

improvements in the manufacturing methods. (This project was co-authored by Billy

Barrios, Steve Lentine, and Ceili Burdhimo).

Leishmaniases are among the most important emerging and resurging

vector-borne diseases, second only to malaria in terms of the number ofaffected people. Leishmaniases are endemic in 88 countries worldwide

and threaten about 350 million people (WHO, 2007). Since the first

reported case of zoonotic cutaneous leishmaniasis (ZCL) in Saida, Algeria,

in 1991, 1,275 cases have been recorded (Makhlouf & Houti, 2010), with

the vast majority of study-area cases (99%) reported between the years

of 2000 and 2009. An investigation of potential climatic indicators for the

apparent shift in disease prevalence was conducted by comparing

anomalies in the climate data specific to the local pathogen cycle. It was

determined that long-term climate trends have resulted in conditions

that promote the prevalence of ZCL. Increased precipitation haveresulted in greater vegetation and promoted host and vector population

growth through a trophic cascade. Increased minimum temperatures

have lengthened the annual duration of sandfly activity. Short-term

variations in maximum temperatures, however. show a correlation with

disease suppression in the subsequent years. These findings indicate a

potential to forecast the risk of ZCL infection through models of the

trophic cascade and sandfly population growth.

Quantum Cascade Lasers (QCLs) can be designed to operate anywhere from

the Mid-IR to THz spectrum, and with their small size, tunable frequencies,and high energy output makes them an excellent choice for Trace Gas

Detection. During the course of this internship, our job was to construct a

laser system capable of producing low enough beat frequencies that could be

detected via a spectrum analyzer. After the internship, the QCL would then

undergo experimentation into detecting various molecules. Research and

experimentation into QCLs will allow them to be used in both Earth science

and future planetary NASA missions. QCLs are relatively new within the field

of spectroscopy and operate on a principle different from that of common p-

n junction diode lasers. In a diode laser, conduction band electrons jump into

a valence band hole and emit a photon whose wavelength is determined by

the band gap energy of the semiconductor, known as an interband transition.With QCLs, a conduction band electron can make a series of jumps in a

staircase-like potential existing in the conduction band, emitting an identical

photon in each transition. Here, a single electron emits a cascade of photons

leading to the formation of a high-power laser. Transitions within a QCL take

place from subband-to-subband inside a quantum well, continuing into the

next quantum well, and so on. Thus, these are referred to as intersubband

transitions.

Hygroscopic growth is one of the most fundamental properties of atmospheric aerosols.

By absorbing or evaporating water, an aerosol particle changes its size, morphology,

phase, chemical composition and reactivity, and other parameters such as its refractive

index. Because of this, extensive research is being done on aerosol particle hygroscopic

growth at NASA. This research is important to the understanding of aerosol effects on

climate change. Currently, the operation of radiosondes is the most common technique

used to characterize vertical profiles of temperature, water vapor mixing ratio and

relative humidity. However, radiosondes are launched only two to three times a day

because of the high cost of each one. The attempted solution to this problem is utilizing a

Microwave Radiometer (MWR). Microwave radiometry allows for continuous retrievals

of temperature profiles by measuring brightness and sky temperature at different zenith

elevations. The focus of this study is the sensitivity of Relative Humidity Profiles obtained

from both instruments. This will be accomplished by using temperature profiles from the

MWR and radiosonde. The result of these comparisons will allow for the study of thesensitivity of the Relative Humidity profile obtained by radiosonde and those combining

temperature profiles from the MWR and the Water Vapor mixing ratio from the

radiosonde. These Relative Humidity profiles will then be compared to Relative Humidity

profiles from the radiosonde. The data used in this study was acquired from the Howard

University Beltsville Campus during the Discover AQ campaign in the summer of 2011.

The result of this project will be used as a baseline for evaluating uncertainties in the

retrieval of aerosol hygroscopic growth by means of Lidar measurement.

The Laser Interferometer Gravitational-Wave Observatory (LIGO) is a large-scale

Michelson interferometer which aims to directly detect gravitational waves

predicted by Albert Einstein in 1916. The gravitational waves sources that LIGO

expects to detect consist of the merging of two neutron stars or a neutron and

black hole at cosmic distances. It is anticipated that the coalescence of these

compact objects may also produce a short -lived gamma ray burst (GRB).

Unfortunately, LIGO is not accurate in localizing the points in the sky where the

gravitational sources are to be found. The best that LIGO can do is to constrain a

gravitational wave source in an area of approximately 100 square degrees,

where literally millions of electromagnetic sources can be observed. So it seems

that the simultaneous detection of gravitational and electromagnetic wavescoming from a source is highly unlikely. To facilitate the task of searching for

electromagnetic counterparts coming from gravitational waves, a list of galaxies

within 100 Mpc has been compiledthe gravitational waves galaxy catalog

(GWGC). LIGO is now being designed to improve its sensitivity by a factor of 10,

which means that it would be able to observe neutron star/ neutron star

coalescence to distances of 300 Mpc and neutron star/ black hole coalescence

up to 650 Mpc. Therefore, GWGC must be updated to contain galaxies at these

distances. We present the results of the updates made to GWGC.

Historically, spacecraft reaction control systems have primarily used cold gas

thrusters because of their inherent simplicity and reliability. However, cold gas

thrusters typically have a low specific impulse. It has been determined that a

higher specific impulse can be achieved by passing a monopropellant fluid

mixture through a catalyst bed prior to expulsion through the thruster nozzle.

This research analyzes the potential efficiency improvements from using tri-

gas: a mixture of hydrogen, oxygen, and an inert gas, in this case helium.

Passing tri-gas through a platinum catalyst causes the hydrogen and oxygen to

become reactive, ultimately heating the exiting fluid and generating a higher

specific impulse. The goal of this project was to optimize the thrusterperformance by characterizing the effects of several system components. The

performance effects were examined by varying catalyst types, catalyst lengths,

and initial catalyst temperatures. Additional testing would utilize a hydrogen

rich tri-gas mixture or characterize the performance effects of firing in a

vacuum chamber for future applications and advancement in the field of green

propellants

The organic contaminants library was developed as part of the contamination control plan for the Mars

Science Laboratory rover mission. Work to normalize the data taken from Sample Analysis at Mars (SAM)

to match standardized organic compound databases such as the National Institute of Standards and

Technology (NIST) is needed in order to increase its availability to other potential users. To do this, we

analyzed a standard fragmentation pattern, in this case Perfluorotributyl amine (PFTBA), using the SAM

GCMS settings that will be used for the actual mission and then calculated the ratio differences between

the SAM PFTBA data and the NIST standard for PFTBA. This library is submitted as a New Technology

Report, and will be readily available in the future. Carrying out a correction of the SAM spectral

response, developing and providing an algorithm that makes these corrections to match with more

standard libraries like NIST, will allow general users to use this library and correct SAM data for their

work. The data is processed by correcting for instrumental calibration, and other specific instrumental

behaviors. The processing is documented in a linked location related to the data directories. This works

for a large number of the continuing satellite missions. The lower level data is primarily available from

the mission operations groups. Although this work is intensive in terms of the GCMS Spectral library, the

changes to the spreadsheets that contain entries supplementing the contaminants library should be

minimal, and only needed when the normalization changes the spectra enough to change the chemical

formula (in those cases the compound is properly identified by the library). With the expected data for

the Mars Science Laboratory (MSL) Curiosity Mars landing being August 6, continued support of the

mission via further library improvements will be needed.

Todays helicopter gearboxes are limited by their poor structural design and

lack of capability to correlate changes in transmission and gearbox noise levels

with expected changes in cabin noise levels. This research focuses on the

development of multifunctional nanocomposite materials that possess high

strength, good thermal conductivity and high-performance abilities in vibration

and noise control. The project seeks to demonstrate improvement in the

vibration damping properties of polymeric materials by the addition of carbon

nanotubes. Carbon nanotubes are commonly used to improve the stiffness,

durability, performance and damping properties of materials. Because of their

adjustable elasticity and ability to act as springs, they can dissipate energy much

more efficiently, becoming a key component in noise-reduction applications.

Some of the greater benefits and payoffs of this research include quieter cabinsand the development of lightweight materials that carry no weight penalties.

These materials have many other applications, especially in the automotive and

aerospace industries where manufacturers require vibration-absorbing

materials that are cost-effective for the production of next-generation vehicles.

This research project involves the synthesis of epoxy nanocomposite materials,

dispersion and organic functionalization of carbon nanotubes, and the

processing and characterization of polymeric samples.

Climate variability in Australia is largely driven by an atmospheric phenomenon called the Southern

Oscillation (SO), which involves a see-saw like behavior between low and high pressure systems within the

equatorial Pacific regions. The interaction of SO with abnormally high sea surface temperatures (SSTs) El

Nio and abnormally low SSTsLa Nia (anti-El Nio) creates extreme drought or extreme flooding,

respectively, throughout Australia. El Nio-Southern Oscillation (ENSO) events have significant impacts on

Australias landscape, ecosystems, agriculture production, and, as this report shows, human health. During

La Nia years, when ENSO events involve increased rainfall and consequential flooding, Australias tropical,

warm climate and an associated increase in vegetation growth from the rainfall creates an ideal habitat for

mosquito population increases. Certain species of mosquitoes (Culux annulirostris) are carriers of Murray

Valley Encephalitis (MVE) virus, a rare but potentially fatal infection that attacks neurological and muscular

functioning. We hypothesized that a widespread increase in vegetation indicates an expansion of ideal

mosquito production habitats and will translate to an increased risk of MVE contraction. Our objective is to

show if a correlation exists between the ENSO-driven climate and consequential ecosystem changes and

MVE outbreaks throughout Australia. This study makes use of the Moderate Resolution ImagingSpectroradiometer (MODIS) sensor operating on NASAs Terra satellite to obtain monthly Normalized

Difference Vegetation Index (NDVI) data. It is assumed in this research that an anomalous increase in NDVI

values indicative of vegetation growth occurs due to increased rainfall, which, in tandem with

Australias tropical climate, allows for NDVI to be an adequate proxy for the combined influence of rainfall

and temperature on mosquito ecology. Our results showed a general temporal and spatial correlation

between MVE outbreaks and a greening period, suggestive of ideal mosquito breeding habitats and

assumed population increases. (This project was co-authored by K.Cortney Gustafson, Mouhamad Diabate,

Friction Stir Welding is a process in which different factors such as travel speed, rotational

speed (RPM), and plunge force play a key role in creating a successful weld. Friction is

created between two panels by a shoulder and pin. This friction causes the material at the

abutting edge of two panels to plasticize (plastically deformed 70 percent of melting

point- taffy consistency), allowing for the material to be stirred and welded. This project

will consist of two separate but equally important tasks. First, is to analyze the nugget

shape and material flow characteristics of conventionally friction stir welded (C-FSW)

panels with different pin tool designs. Analyzing the nugget shape and stirring of the weld

through optical microscopy will aid in understanding how these flats will affect a weld.

There are six different pin tool designs for this project: a standard C-FSW pin without

machined flat edges (baseline), and five others with flats ranging from 1 to 5. The panels tobe welded are aluminum 2219 to aluminum 2219. This project will aid in understanding the

differences and similarities between each of the pins. This work will ultimately aid in

determining which pin design provides the optimum weld schedule and characteristics.

Second, is to support fixture design, stress analysis (FEA), and procurement for the Multi-

purpose Crew Vehicle Stage Adapter (MSA) pathfinder cone to adapter ring weld for the

Space Launch System (SLS). (The research was co-authored by Daniel H. Hernandez Jr. and

Elvis Boves).

The Deep Space Network (DSN) is an international antenna network funded by NASA which

provides communications and support for various space missions. A 34-meter beam

waveguide antenna is under construction in Canberra, Australia, and requires a new downlink

channel and telemetry processors. This project focuses on testing of new telemetry decoders

which are implemented on Field-Programmable Gate Array (FPGA) boards. These are also

intended to replace legacy telemetry processors in the future to improve ease of maintenance

and sustainability. The intended functionality and performance of the decoders must be the

same as those which they are replacing. The new decoders are tested using different code

rates, coding schemes and modulation schemes standard to the DSN. The testing process

utilizes equipment similar to those at DSN ground stations, along with a signal generator to

provide equivalent RF signals. The Python scripting language is used to verify the integrity ofdecoded data and can handle large sets. These tools are used to obtain characteristics of

performance such as symbol error rate (SER), bit error rate (BER), and signal-to-noise-ratio

(SNR). Throughout the course of the internship, the encoding scheme that was of primary

focus was Turbo Code using code rates and modulation schemes seen on the actual DSN.

Discrepancies in decoder performance were encountered during testing, with several sources

identified. Various parameters were added to the output to isolate different sections of the

test setup for identifying those sources of error.

Using Interactive Data Language (IDL), an established data visualization

software, I analyze infrared spectroscopic observations of protoplanetary

disks. The observations are taken with the Very Large Telescope (VLT) in

the Atacama Desert of Chile using the Cryogenic Infrared Echelle

Spectrograph (CRIRES). Observing protoplanetary disks, or the gas and

dust around early stars, gives us insight as to what material surrounds

early stars, and since planets form in the protoplanetary disk of the star,

investigating the chemical composition of protoplanetary disks allows us

to probe the material that will eventually make up the planets around a

certain star. Planets whose origins and compositions we would like to

better understand include the recent discoveries of "super-Earths."

Observing these super-Earths gives us minimal information as to what

they are composed of, but observing protoplanetary disks can help us

better understand the origins of the atmospheres and interiors of these

planets.

Gravitational wave detectors in the mHz band (such as the Laser

Interferometer Space Antenna, or LISA) will observe thousands of compact

binaries in the galaxy which can be used to better understand the structure

of the Milky Way. To test the effectiveness of LISA to measure the

distribution of the galaxy, we simulated the Close White Dwarf Binary

(CWDB) gravitational wave sky using different models for the Milky Way. To

do so, we have developed a galaxy density distribution modeling code based

on the Markov Chain Monte Carlo method. The code uses different

distributions to construct realizations of the galaxy. We then use the FisherInformation Matrix to estimate the variance and covariance of the recovered

parameters for each detected CWDB. This is the first step toward

characterizing the capabilities of space-based gravitational wave detectors to

constrain models for galactic structure, such as the size and orientation of

the bar in the center of the Milky Way.

In the last decade, there has been an

increased interest in using palladium (Pd)

nanostructures for hydrogen (H2) sensing

devices. Nanostructured based sensors

promise shorter response times and higher

sensitivity due to their high surface-to-

volume ratio. With this in mind, an anodic

alumina membrane (AAM) Pd

nanostructured based sensor has beendeveloped and tested. The Solid State

Reduction method used formed a

combination of a thin film and nanowires

in the AAM. The fabrication method and

preliminary test results are discussed here.

The Advanced Multimission Operations System (AMMOS) offers missions operationstools and services to deep space missions that are reliable and cost-effective. The

Instrument Operations Subsystem (IOS) of AMMOS deals with the processing of data

from space, and provides tools to orbiters and observatories for tactical operations

related to image processing and instrument design. Currently, up to 189

measurements from Mars' surface (such as wind speed, temperature, and

atmospheric pressure) are available to observers in the form of raw data. However,

this data is recorded every two seconds, making the amount of data enormous and

more difficult to sift through for specific information. Using Javascript/jQuery, a more

aesthetically pleasing way of viewing this information was developed and

demonstrated to make it easier for scientists to dissect. Tools such as the Mars Image

Viewer (MIV) are required from low-volume, relatively simple missions to high-volume, complex missions. Primary users of the MIV were observed in their workspace

and surveyed. Secondary users were also queried on their interest in and the usability

of the tool. The interaction between the MIV and its current/potential users were

analyzed in order to define requirements and ensure that it adequately fit the needs

of the users in ways that enable them to reach their goals with optimal efficiency.

Recommendations were provided for the MIV users manual to further cater to the

standpoint of the novice user.

This project involved Total Ionizing Dose (TID) tests at the

GSFC radiation chamber. The tests were performed using

a TLE2022 Bipolar Op Amp as the Device Under Test

(DUT).

The DUT was subject to a Cobalt 60 source at a Low Dose

Rate (LDR). The main values observed were the input bias

current, supply current, voltage offset, and current offset.

The implication from the results support that the device

has characteristics of radiation hardened.

The number of crew members in commercial flights has steadily

decreased to two members, down from five members 50 years

ago. The next step is to reduce the crew to one pilot, and

eventually fully automate commercial aircraft, with one ground

pilot managing numerous UAS. This reduction in crew will

reduce costs for major airliners. Consistent development of new

aeronautic technologies has enabled this drastic shift to be

possible. The (FDRL) at NASA Ames is getting involved in theresearch efforts for the upcoming changes. My task as an intern

was to develop a cognitive walkthrough and work directly with a

commercial pilot to create testing scenarios and flowcharts for

the experimental testing on single-pilot operations.

Lithium ion batteries using Li2MnO3/LiMO2 (M = Mn, Co, Ni) as the cathode had

been extensively studied. Under 0 C, batteries with this composite oxide present

efficiency issues. This can be explained by a diffusion process with the lithium as

consequences of the poor layer organization. LiCl salts can help improve this

organization by resupplying the intercalated lithium to a molten mixture. Sensitivity

studies directed to understand the effects of LiCl on the cathode material

controlling variables as the synthesis time, and LiCl concentration will be

accomplished. Electrochemical experiments using galvanostatic charge/dischargeprocesses at C/5 and C/10 and impedances at different temperatures provide direct

information of the diffusion and the dynamics of the batteries prepared with

Li2MnO3/LiMO2. Tap density analysis will be completed to have a better

understanding of the behavior of the cathode after being packed in the batteries

and an AlPO4 coating. Results show an improvement in the capacity of the cathode

after the LiCl flux.

The Dryden Aero-Elastic Lab located at the AERO Institute is developing

cutting-edge research in fiber optic strain sensing. The innovative fiber

optics systems are capable of monitoring mechanical and thermal strains,

which allow engineers to monitor real-time deformation of a structure.

Utilizing the NASA University Research Center (S.P.A.C.E.) Uninhabited

Air Vehicle (Odyssey) as a test bed for the fiber optics strain sensors,

engineers will validate the capabilities of the Fiber Bragg Grating sensors.

The use of finite element modeling will aid in the further development of

embedded Fiber Bragg Grating sensors for Uninhabited Air Vehicles.

With real-time, deformation-shape prediction, it will be possible toaccurately measure mode-shape deformations of aircraft wings due to

aero-elastic effects on the aircraft during flight. Structural deformation

data can be sent to a feedback control system to mitigate the aero-

elastic effects on the airframe. Methods developed by NASA's Dryden

Flight Research Center for real-time deformation-shape prediction of

lightweight unmanned flying aerospace structures can potentially reduce

the risk of in-flight breakups, such as that of the Helios Wing..

An experimental study was conducted on the Mid-Atlantic region to investigate the rainfallvariability within the instantaneous field of view of the microwave sensor-based satellite rainfall

estimate. The study was conducted through 30 rain gauges that were deployed at 11 sites, where

eight sites had triple and remaining sites had dual gauges. The gauges were tipping bucket at 0.01

inches resolution. The time of the t ip was recorded to a data logger which is powered by lithium

battery. A continuous gauge record was obtained at every gauge site from May 2005 to September

2010. The gauges sites were distributed from Ocean City, Maryland, to Kiptopeke, Virginia, at a

maximum separation of 150 km and at a minimum separation of 1 km between the two sites at

Wallops Island, Virginia. This study focuses on the variability of rainfall at different climatological

periods. The observations were divided into 20 seasons, 10 cold/warm periods, and five years. A

stretched exponential model was applied to the correlations of paired gauge rainfall at 30-minute

integration period. Two tips (0.5 mm) were considered as the threshold for rain events. The

correlations fell below 50 % at a 10 km distance most of the time in an observational period, whilethey were below 20% at 40 km distance. The variability was more noticeable between the seasons

than between the warm/cold periods and between the years. This could, in part, be related to the

sample size, partly to differences in rainfall characteristics. Additionally, the remnants of tropical

cyclones bring abundant rainfall to the Mid-Atlantic region but they may not be observed at a given

year. The nugget parameter was mainly above 0.95, while the shape parameter was mainly

between 0.4 and 1.0. The correlation distances remained mostly less than 50 km at a given

observational period.

This study examined the effect of force feedback on target

acquisition in a simulated task, using a computer mouse

and the Novint Falcon, with and without force-feedback

information. Participants were asked to select targets that

varied in size, distance, and angular direction from the

start location. Results showed significant differences

between the movement times for the various input

devices. Movement times with the mouse and the Falcon

with force feedback were significantly faster than the

Falcon without force feedback. Force feedback was foundto reduce the effect of target size, but not the effect of

target distance. Force feedback also produced faster

movement times when the direction of movement was in

two dimensions. The findings suggest that force feedback

may be a useful method for assisting pilots in future CDTIs.

When charged particles pass through CR-39 detectors, they lose

energy and break the molecular bonds of the CR-39 polymer to form

paths of high chemical reactive sites along their trajectories. These

trajectories can be revealed as etched cones on the surfaces of CR-39

detectors by chemical etch for a CE-39 plate. Chemical etching for

plastic nuclear track detectors (CR-39) and thermoluminescence

measurements were performed per established techniques currently

used by the Space Radiation Analysis Group (SRAG) at NASA/JSC.

Work objectives included: working with the sodium hydroxide (NaOH)

etching solution, etching the plastic nuclear track detectors,measuring the detectors pre- and post-etch. The goal was to

calculate the bulk etch and prepare the detectors for storage for

future analysis. Over 150 CR-39s were etched successfully and the

bulk etch values were analyzed for accuracy using the standard errors

and error propagation..

The sustainability of aviation directly depends on the availability ofenvironmentally responsible fuel. With the growing gap between petroleum

production and demand, increasing prices, carbon emissions, mounting

environmental regulations, and the limited concentration of known fuel

reserves in politically unstable regions, biofuels are considered a viable

alternative to securing the future of aviation. Biofuels are a renewable

energy source, which could be customized to meet specific fuel needs.

NASA GRC developed the GreenLab Research Facility to study two principal

sources of biofuels: arid land halophytes (salt-tolerant plants) and sea water

algae. Through a Life Cycle Assessment (LCA) of the GreenLab, we

investigated the benefits and contributions to motivating the nextgeneration in STEM-related fields that the facility and its research offer

outweighs the cost of running the program every year. We also looked into

the optimization of Chaetomorpha sp. macro-algae by studying its growth

under four different conditions. Results showed that a direct light source

and some dirt accumulation lead to more successful growth of

The aim of this project is to demonstrate techniques for effectively penetrating

a radio-shielded enclosure using Ethernet cable (CAT-6). This process requires

that we measure the shielding performance by means of testing and data

orchestration to collect and analyze our data, and then present observations

with different test cases. Each test case would represent a different penetration

strategy that utilizes distinctive wire coupling and characteristics (i.e., the type

of bulkhead link, the twist of each CAT-6 cable, the shielding type of each CAT-6

cable, and the length of the cable). As the different cable setups are fabricated,

a prototype evaluation of setup is conducted to measure the signal integrity of

the testing configuration. Our signal integrity is measured through the analysisof different parameters found in the prototype evaluation such as RF leakage,

impedance mismatch, and decay rate. As data values are effectively collected

and analyzed, the most effective cable setup is selected based upon its ability to

penetrate the shielded enclosure. The testing data are compared in conjunction

with the cost of the manufacturing of the prototype wire penetration.

Lithium-ion batteries are among the most energetic rechargeable batteries available,

making them very popular for various applications. A lithium-ion rechargeablebattery provides high energy density, requiring less weight and smaller size

compared to other rechargeable systems. The battery manufacturer ABSL selected

the Sony Lithium 18650 HC cell in the late 1990s to make its space-qualified cells.

NASA Goddard Space Flight Center has flown ABSL batteries built from Sony 18650

HC cells on ST-5, SDO and LRO missions. Recently, Sony made modifications to these

cells due to failures in terrestrial applications. The addition of a mandrel tube is

supposed to "improve the vent path within cell to the safety vent" (Troutman, Joe,

2011) without causing any changes in the performance of the cell and the built-in

safety features. The aim of my project was to establish the baseline characterization

of the life-test batteries, which the contractors at the Naval Surface Warfare Center

at Crane, Indiana, will use to compare later performance tests of the Sony 18650 HC

and Sony 18650 HC mandrel cells. The study consisted in the creation of a test planthat allows researchers to know the capacity of the battery and its behavior in

different environments. The test plan was conducted in the Battery Laboratory at

NASA Goddard Space Flight Center. The project exposed me to Integration and

Testing (I&T) in a Class 10,000 clean room, visits to contractors and vendors (SAFT,

ABSL), and the opportunity to travel to the Naval Surface Warfare Center at Crane,

Indiana. (This project was co-authored by Loraine Torres-Castro, Leonine S. Lee,

The overall objective is to assess the potential of satellite Lidar to retrieve thesurface of the coastal tides during normal (non-surge) conditions. Specific

objectives are to assess the capability of the GLAS sensor on board the ICESat

satellite platform to retrieve the spatial water surface profile during a March 2006

transect over the Chesapeake Bay, using the 1064 wavelength; validate the

retrieved water levels using a calibrated, high resolution 2D hydrodynamic model;

and provide insight on future altimetry observations of coastal regions using Lidar.

The present study focuses specifically on the capability to retrieve water surface

elevations of the Chesapeake Bay during a single ICESat transect in March 2006.

Validation is achieved using water surface elevations with a calibrated 2D, high-

resolution hydrodynamic model. This is because ICESat observations do not fall

exactly over available in situ tidal gages. Thus, it is necessary to first calibrate themodel using tide gages. Then, one can compare the ICES at elevations to those grid

elements over which the satellite observations occur. Future Lidar altimeters, that

will provide higher vertical precision and spatial coverage, should be of significant

benefit not only to hydrodynamic modelers, but also to a wide range of

applications including water resources planning, weather forecasting, ecosystem

monitoring, and disaster prevention and management.
