 | The visual requirements for augmented reality or virtual environments displays that might be used in real or virtual towers are reviewed with respect to similar displays already used in aircraft. As an example of the type of human performance studies needed to determine the useful specifications of augmented reality displays, an optical see-through display was used in an ATC Tower simulation. Three different binocular fields of view (14 , 28 ... |

| The system for the production and distribution of the United States supply of influenza vaccine has experienced disruptions during past influenza seasons. The identification of elements of the influenza vaccine is different each year and must be researched and identified each year prior to the influenza season. The manufacturing of the vaccine is a complicated process with many potential problems. This thesis identifies the requirements and constraints of the current ... |

Mira O. Jung; GEORGETOWN UNIV WASHINGTON DC
|
| Failure of conventional treatment of prostate cancer with radiotherapy may be due to intrinsic resistance of the tumor cells. One of mechanisms underlying intrinsic radiation sensitivity is linked to the state of chromatin architecture. The long-term goal of this proposal is to develop a novel therapeutic strategy by enhancing radiosensitivity of prostate cancer cells by testing the hypothesis that an increase of cellular radiation sensitivity may be achieved by exposure ... |

| This thesis provides an analysis of the diminishing sea ice trend in the Arctic Ocean by examining the NPS 1/12-degree pan-Arctic coupled ice-ocean model. While many previous studies have analyzed changes in ice extent and concentration, this research focuses on ice thickness as it gives a better indication of ice volume variability. The skill of the model is examined by comparing its output to sea ice thickness data gathered during ... |

|
| The interplay between sensors and camouflage has long presented a problem for modeling target acquisition performance of human-in-the-loop thermal sensors. For instance, ACQUIRE, a commonly used target acquisition model, is relatively more sensitive to target size than target contrast. The result is that ACQUIRE generally predicts that low contrast targets will be detected at ranges similar to baseline targets. Thus ACQUIRE has had limited success for camouflage evaluation, since it ... |

 | Our research is focused on an investigation of automated road tracking using multiple images, toward a goal of fully automated extraction of 3D road networks with topology and attribution. The use of multiple images for road tracking makes the process more robust, due to analysis of the scene from different view points. It also supports direct extraction of 3D information along the path of the road. Determination of road elevation ... |

|
| The CDk4/6 kinase has elevated activity in spontaneous breast cancer, making it an excellent candidate for targeted inhibition for the treatment of breast cancer. We propose to prepare a CDK4/6-specific kinase inhibitor that is based on the naturally occurring CDK4/6 specific inhibitory proteins of the INK4 family. Since the INK4 proteins are notoriously unstable, we have been working towards the preparation and structural characterization of INK4 proteins with improved thermostability ... |

| For the past eight years, the small automated telescope Raven has been tested in detecting and tracking deep space objects. As the Raven has proven successful in tracking this regular and predictable orbit, its one arc-second accuracy made it a perfect candidate to attempt to accurately track the less predictable Highly Eccentric Orbit (HEO) objects. Ranging data was obtained from the Sirius satellite radio company for the Sirius3 satellite (Satellite ... |

| I have made considerable progress on the research project that I outlined in the pre-doctoral DOD breast cancer research fellowship proposal. The proposal aimed to determine targets for the ubiquitin ligase activity of BRCA1. BRCA1 (Breast Cancer susceptibility gene 1) is an important tumor suppressor that protects mammary cells from malignant transformation. Recently BRCA1 has been found to have an enzymatic function as an ubiquitin ligase. Ubiquitin ligases tag other ... |

Anjan Nan; MARYLAND UNIV BALTIMORE
|
| The overall purpose of this project is to develop targetable water-soluble polymerantiangiogenic drug conjugates for systemic breast cancer therapy. The rationale is that by selectively targeting polymer-antiangiogenic drug conjugates to alpha-v-beta-3 receptors on endothelial cells of tumor neovasculature; it is possible to restrict the biodistribution of the antiangiogenic drug to the vascular space, thereby increasing tumor accumulation and subsequent antitumor potency of the drug and decreasing dose-limiting toxicity.

Ioannis Kassalias; NAVAL POSTGRADUATE SCHOOL MONTEREY CA
|
| The accurate determination of spacecraft attitude has always been a critical issue in many applications. The presence of imperfect sensors introduces errors in the system and affects the outcome of the mission. One of the most significant sensors is the rate gyroscope. Particularly, the rate gyros are known to degrade with time, introducing random noise and bias. This calls for estimation algorithms which process the measured data in order to ... |

|
| As part of the High Accuracy Network Determination System (HANDS), Raven-class telescopes were built to provide observations with less than an arcsecond of error. While achieving low noise levels, previous work has shown that HANDS optical data contain systematic errors which limit orbit determination accuracy; therefore, the challenge is being able to fully utilize that data to produce deep-space orbits with great certainty. This paper presents findings that better define ... |

| The attitude determination and control subsystem requirements or various payloads on the FalconSAT 3 satellite are stringent enough to demand some type or data processing in order to meet attitude determination requirements. This paper details one data filter, the Kalman filter, and more specifically, the 7-state and 6-state Kalman filters. Both filters prove to meet the attitude determination requirements successfully with little difference in achieved accuracy. However, the 6-state filter ... |

| Progression to irreversible shock may not be clinically apparent until a patient has been given several liters of fluids as well as multiple units of blood and blood products. In combat situations or in situations in which fluids for resuscitation are limited, resources need to be appropriately allocated. Therefore, early differentiation between patients who will progress to irreversible shock and those who are resuscitatable is important. We investigated whether the ... |

| Many military systems must be capable of sustained operation in the face of mechanical shocks due to projectile or other impacts. The most widely used method of quantifying a system's vibratory transient response to shock loading is called the shock response spectrum (SRS). The system response for which the SRS is to be determined can be due, physically, either to a collocated or to a noncollocated shock loading. Taking into ... |

| GaN thin films have been doped with varying Er concentrations (0.01 -10 at.%) during molecular-beam- epitaxy growth. As expected, the visible and infrared (IR) emissions, from photoluminescence (PL) and electroluminescence (EL), are a strong function of Er concentration. We report on the determination of an optimum Er doping level for PL and EL intensity. Secondary ion mass spectroscopy and Rutherford backscattering measurements showed that the Er concentration in GaN increased ... |
