Abstract:
Application of power MOSFETs in spaceborne power converters was simulated by exposing devices to low-dose-rate ionizing radiation. Both radiation-hardened and nonhardened devices were tested with constant and switched gate biases during irradiation. In addition, some of the devices were under load. The threshold-voltage shifts were strongly bias dependent. The threshold-voltage shift of the nonhardened parts was approximately dose-rate independent, while the hardened parts exhibited significant dose-rate dependence. A pre-anneal dose-rate dependence was found for the interface-state buildup of

Abstract:
Space radiation is significantly harmful to electronic Components. The operating time, duration and orbit of the space mission are affected by the characteristic of the radiation environment. The aging and the performance of the electronic components are modified by radiation. The performance of the space systems such as electronic units, sensors, power and power subsystem units, batteries, payload equipments, communication units, remote sensing instruments, data handling units, externally located units, and propulsion subsystem units is determined by the properly functioning of various electr

A total of 69 employees in various job positions working in cubicles in an open-office space plan, of a large organization, completed a questionnaire investigating the impact of microenvironmental space on communication and job satisfaction.

We numerically explore the performance of the time reversal approach in terms of temporal and spatial focussing in three different propagation environments: free space, partially reflected medium and fully reflected medium. Performance of the phase conjugation scheme is experimentally investigated in partially reflected medium and fully reflected medium based on the characteristics of focus sing and steering capabilities. We have explored numerically the E-field time evolution along the propagation path and the beam steering action of a 2.45 GHz time reversal retrodirective array using dipole

This thesis evaluates the suitability of silicon-germanium technology for electronic systems intended for extreme environments, such as ambient temperatures outside of military specification (-55 degC to 125 degC) range and intense exposures to ionizing radiation. Silicon-germanium devices and circuits were characterized at cryogenic and high-temperatures (up to 300 degC) and exposed to ionizing radiation, providing empirical evidence that silicon-germanium is an excellent platform for terrestrial and space-based electronic applications.

This work represents several years' research into the field of radiation hardening by design. The unique characteristics of a SiGe HBT, described in Chapter 1, make it ideally suitable for use in extreme environment applications. Chapter 2 describes the total ionizing dose effects experienced by a SiGe HBT, particularly those experienced on an Earth-orbital or lunar-surface mission. In addition, the effects of total dose are evaluated on passive devices. As opposed to the TID-hardness of SiGe transistors, a clear vulnerability to single-event effects does exist.

Abstract:
Low Earth orbit represents a valuable limited natural resource. Of particular interest are sun-synchronous orbits; it is estimated that approximately 44% of low Earth satellites are sun-synchronous. A previously developed sun-synchronous orbit slot architecture is considered. An in-depth analysis of the relative motion between satellites and their corresponding slots is performed. The long-term evolution of Earth's orbital environment is modeled by a set of coupled ordinary differential equations. A metric for quantifying the benefit, if any, of implementing a sun-synchronous architecture is d

Abstract:
The space environment contains many harsh characteristics that are harmful to spacecraft and threaten the success of space missions. Atomic oxygen (AO) and outgassing are among the chief concerns that spacecraft engineers must design for in order to ensure the safety of a spacecraft. AO is monatomic oxygen (O1) that is created when Ultraviolet (UV) radiation photochemically disassociates diatomic oxygen (O2) in space. AO is the dominant atmospheric constituent between 175 and 600 km, and is a great concern in low earth orbits. Orbital AO has an average impact energy of 4.5 ± 1 eV with orbiting

Familiar birds tended to associate more closely than strangers, though hens preferred visual contact with a stranger to isolation.

Abstract:
Urban morphology in combination with soundscape planning and design are important parameters towards the development of sustainable cities. Towards this direction this study primarily investigates the effect of urban morphology and green-space related parameters on traffic noise in different analysis levels. Secondly, it complements this first objective approach with a subjective one, investigating peoples’ perceptual attributes using auditory and visual stimuli. Both approaches aim at merging the gap between acoustics and planning on the grounds of the new holistic approach of urban sound pla

Abstract:
This thesis describes the application of parallel simulation techniques to represent the structured functional parallelism present within the Space Shuttle Operations Flow using the Synchronous Parallel Environment for Emulation and Discrete-Event Simulation (SPEEDES), an object-oriented multi-computing architecture. SPEEDES is a unified parallel simulation environment, which allocates events over multiple processors to get simulation speed up. Its optimistic processing capability minimizes simulation lag time behind wall clock time, or multiples of real-time. SPEEDES accommodates an increase
