#### Acceptance Of The Autonomy Required For Interplanetary Small Spacecraft Missions By The Scientists Who Will Use The Data, Jeremy Straub

##### Jeremy Straub

Small spacecraft operating at a distance from Earth are constrained by communications in several ways. The delay between message trans- mission, receipt at Earth, and eventual receipt of a reply can be significant. Further, gain and transmission power limitations (introduced by spacecraft form factor constraints and the resulting limitation on antenna size and power generation capabilities) constrain the amount of data that can be sent and received. This drives a need for mission autonomy: a requirement that the spacecraft be able to manage its own operations and choose the data that it should collect and transmit, based on high-level instructions ...

#### Hilbert Space Theory And Applications In Basic Quantum Mechanics, Matthew Gagne

##### Mathematics

We explore the basic mathematical physics of quantum mechanics. Our primary focus will be on Hilbert space theory and applications as well as the theory of linear operators on Hilbert space. We show how Hermitian operators are used to represent quantum observables and investigate the spectrum of various linear operators. We discuss deviation and uncertainty and briefly suggest how symmetry and representations are involved in quantum theory.

Level Crossing Times In Mathematical Finance, 2013 East Tennessee State University

#### Level Crossing Times In Mathematical Finance, Ofosuhene Osei

##### Electronic Theses and Dissertations

Level crossing times and their applications in finance are of importance, given certain threshold levels that represent the "desirable" or "sell" values of a stock. In this thesis, we make use of Wald's lemmas and various deep results from renewal theory, in the context of finance, in modelling the growth of a portfolio of stocks. Several models are employed .

Effects Of Hru Size On Prms Performance In 30 Western U.S. Basins, 2013 Portland State University

#### Effects Of Hru Size On Prms Performance In 30 Western U.S. Basins, Madeline Olena Steele

##### Dissertations and Theses

Semi-distributed hydrological models are often used for streamflow forecasting, hydrological climate change impact assessments, and other applications. In such models, basins are broken up into hydrologic response units (HRUs), which are assumed to have a relatively homogenous response to precipitation. HRUs are delineated in a variety of ways, and the procedure used may impact model performance. HRU delineation procedures have been researched, but it is still not clear how important these subdivision schemes are or which delineation methods are most effective. To start addressing this knowledge gap, this project investigated whether or not HRU size has a significant effect on ...

A Cauchy Problem For Some Local Fractional Abstract Differential Equation With Fractal Conditions, 2013 China University of Mining & Technology

#### A Cauchy Problem For Some Local Fractional Abstract Differential Equation With Fractal Conditions, Yang Xiaojun, Zhong Weiping, Gao Feng

##### Xiao-Jun Yang

Fractional calculus is an important method for mathematics and engineering [1-24]. In this paper, we review the existence and uniqueness of solutions to the Cauchy problem for the local fractional differential equation with fractal conditions $D^\alpha x\left( t \right)=f\left( {t,x\left( t \right)} \right),t\in \left[ {0,T} \right], x\left( {t_0 } \right)=x_0 ,$ where $0<\alpha \le 1$ in a generalized Banach space. We use some new tools from Local Fractional Functional Analysis [25, 26] to obtain the results.

Challenges And Prospects Of Processes Utilising Carbonic Anhydrase For Co2 Separation, 2013 Wroclaw University of Technology

#### Challenges And Prospects Of Processes Utilising Carbonic Anhydrase For Co2 Separation, Patrycja Szeligiewicz, Wojciech M. Budzianowski

##### Wojciech Budzianowski

This article provides an analysis of processes for separation CO2 by using carbonic anhydrase enzyme with particular emphasis on reactive-membrane solutions. Three available processes are characterised. Main challenges and prospects are given. It is found that in view of numerous challenges practical applications of these processes will be difficult in near future. Further research is therefore needed for improving existing processes through finding methods for eliminating their main drawbacks such as short lifetime of carbonic anhydrase or low resistance of reactive membrane systems to impurities contained in flue gases from power plants.

#### Mapping And Decomposing Scale-Dependent Soil Moisture Variability Within An Inner Bluegrass Landscape, Carla Landrum

##### Theses and Dissertations--Plant and Soil Sciences

There is a shared desire among public and private sectors to make more reliable predictions, accurate mapping, and appropriate scaling of soil moisture and associated parameters across landscapes. A discrepancy often exists between the scale at which soil hydrologic properties are measured and the scale at which they are modeled for management purposes. Moreover, little is known about the relative importance of hydrologic modeling parameters as soil moisture fluctuates with time. More research is needed to establish which observation scales in space and time are optimal for managing soil moisture variation over large spatial extents and how these scales are ...

#### Determination Of Kinetic Parameters From The Thermogravimetric Data Set Of Biomass Samples, Karol Postawa, Wojciech M. Budzianowski

##### Wojciech Budzianowski

This article describes methods of the determination of kinetic parameters from the thermogravimetric data set of biomass samples. It presents the methodology of the research, description of the needed equipment, and the method of analysis of thermogravimetric data. It describes both methodology of obtaining quantitative data such as kinetic parameters as well as of obtaining qualitative data like the composition of biomass. The study is focused mainly on plant biomass because it is easy in harvesting and preparation. Methodology is shown on the sample containing corn stover which is subsequently pyrolysed. The investigated sample show the kinetic of first order ...

#### Currents, Primitive Cohomology Classes, And Symplectic Hodge Theory, Yi Lin

##### Yi Lin

Tseng and Yau developed primitive cohomology theories on symplectic manifolds. In addition, they proposed a definition of primitive homology, and proved that there is a natural homomorphism from the primitive homology to the primitive cohomology. Inspired by the work of Tseng and Yau, we develop a new approach to the symplectic Hodge theory, and prove in this paper that there is a Poincar\'{e} duality between the primitive homology and cohomology for any compact symplectic manifold with the Hard Lefschetz property. Among other things, we introduce a De Rham complex of real flat chains on symplectic manifolds, and use it ...

Electric Currents Due To Stress-Activated Positive Hole Charge Carriers In Ice, 2012 Michigan Technological University

#### Electric Currents Due To Stress-Activated Positive Hole Charge Carriers In Ice, Cary T. Keller P.E., Friedemann T. Freund, Dale P. Cruikshank

##### STAR (STEM Teacher and Researcher) Presentations

Jupiter’s satellite Europa, whose surface is composed of ice with a possible water ocean beneath, could conceivably serve as an abode for extraterrestrial life. This and other icy celestial bodies may contain organic macromolecular solid material that is produced when surface ices are exposed to ultraviolet radiation and/or electrical energy. Tidal and tectonic stresses or meteorite impacts in icy crusts may produce electrical discharges, which would provide the energy for in-situ synthesis of the organic solids. This electrical energy can be provided by positive hole charge carrier activation. Positive holes exhibit properties such as the ability to flow ...

#### Hydrologic Modeling To Examine Land Use Change Impacts (1970’S And 2005) On The Sediment Yield And Flow Regime In Cayuga Creek, Niagara County, New York, Kimly Reth

##### Multidisciplinary Studies Theses

This research aims to assess the water quality and the land use change impacts on sediment concentration and flow regime in Cayuga Creek, Niagara County, NY for two land use periods, 1970’s and 2005. The 1970’s land use, classified by the USGS, had a significant error. Therefore, the scenario of sediment yield and discharge level to land use change is more of a “what if” since the 1970’s land use was classified incorrectly. The Soil and Water Assessment Tool (SWAT)was used to simulate flows and sediment concentrations for the two land use scenarios using the same ...

Technical Factors Utilised By Elite Archers: Towards Setting An Agenda For Archery, 2012 Bournemouth University

#### Technical Factors Utilised By Elite Archers: Towards Setting An Agenda For Archery, Andrew J. Callaway, Shelley A. Broomfield

##### Andrew J Callaway

Archery, in one form or another, has been around for thousands of years yet research into what makes an archer 'good' is still in its infancy. There are several variations over bow type and different competitions which can be competed, previous works have focused on Recurve (Olympic) bow types whilst Compound have generally been ignored. Research in the area has tended to focus on muscle activation patterns using Electromyography (EMG) and aiming based studies, where generally scores are used as a factor to correlate to.

AIM: The aim of this research is to offer a development from the use of ...
