Hybrid FPGA and GPP Implementation of IEEE 802.15.4 Physical Layer
In this thesis, two different cases of hybrid IEEE 802.15.4 PHY (Physical Layer) implementation are explored. The first case is an FPGA implementation of IEEE 802.15.4 PHY on the Xilinx Spartan-3A DSP FPGA of USRP N210. All of the signal processing tasks are performed on the FPGA, while less …

Coarse Radio Signal Classifier on a Hybrid FPGA/DSP/GPP Platform
… uncertainties in the General Purpose Processor (GPP) software itself. Solving the timing and latency problems requires running key parts of the software-defined radio (SDR) code on a Field Programmable Gate Array (FPGA)/Digital Signal Processor (DSP)/GPP based hybrid platform. Our objective is to …

Remote sensing-based assessment of Gross Primary Production (GPP) in agricultural ecosystems
… agricultural yield. Gross primary production (GPP) of agricultural ecosystems is the amount of total carbon assimilated by the planted crops and the driver of useful biomass production. To assess the GPP of croplands, this study combines information from flux determinations with eddy covariance …

A joint analysis of gross primary production and evapotranspiration of Australia using eddy covariance, remote sensing and land surface modelling approaches
… the patterns of gross primary production (GPP) and evapotranspiration (ET) across Australian biomes in combination of eddy covariance, remote sensing and land surface model (LSM) methods, taking advantage of their respective applicability on different space and time scales. To do this, I …

Seasonal Variation in Whole Stream Metabolism across Varying Land Use Types
… these data to estimate gross primary production (GPP) and ecosystem respiration (ER). GPP and ER were compared to stream chemistry, light, land cover, and storms. I found that there is greater influence of local riparian land cover than watershed land cover on GPP and ER. Streams had varying …

The Flow Regime of Function: Influence of flow changes on biogeochemical processes in streams
… from the production (gross primary production; GPP) and consumption (ecosystem respiration; ER) of dissolved oxygen. With these data, I evaluated how low and elevated flows differentially impact water quality (e.g., turbidity, conductivity) and metabolism using segmented metabolism- and …

GraphPipe: Improving the Performance and Scalability of DNN Training with Graph Pipeline Parallelism
… paper, we develop graph pipeline parallelism (GPP), a new pipeline-parallel scheme that partitions a DNN into pipeline stages whose dependencies are identified by a directed acyclic graph. GPP generalizes current sequential pipeline stages. By constructing the pipeline based on the DNN …

The Effect of Elevated Carbon Dioxide and Ozone on Soybean Development, Leaf Anatomy and Productivity
… photosynthesis or gross primary production (GPP). A draw-back of FACE is that GPP cannot be measured directly. Measurements of micrometeorology, leaf photosynthetic properties and canopy structure were combined in an adapted version of the Integrated Scientific Assessment Model (ISAM) to …

A Comparative Study of the Time-Series Behavior and Predictive Ability of Historical Cost Earnings and General Purchasing Power Adjusted Earnings: An Empirical Investigation
… predictive ability of general purchasing power (GPP) accounting numbers. Accordingly, the primary objective of this study is to gather empirical evidence on the time-series behavior of both historical cost and GPP adjusted earnings series, and to use the Box-Jenkins (B-J) methodology to compare …

Investigations of Bicyclo(3.1.1)heptane Terpenes in Higher Plants: Stereochemistry of Pinene Biosynthesis and Isolation of Bergamoten-12-Oic Acids
… are known to convert geranyl pyrophosphate (GPP) to the bicyclic monoterpenes (+)-$\alpha$-pinene (cyclase I) and ($-$)-$\alpha$-pinene and ($-$)-$\beta$-pinene (cyclase II). The stereochemical course of these cyclizations at the gem dimethyl position of the pinene products was investigated. …

Land-atmosphere exchange of carbon in a high-Arctic wet tundra ecosystem
… with soil temperature, gross primary production (GPP), active layer thickness and soil organic acids. The spatial variability in CH4 fluxes was closely correlated to water table depth (WtD), species compo-sition and soil organic acids. The CH4 fluxes remained low during autumn and early winter of …

The effects of terrestrial sediment inputs on ecosystem functions in seagrass meadows and unvegetated sediments
… sandflat. Submerged gross primary production (GPP) in both habitats and emerged GPP in the seagrass habitat were strongly controlled by light availability. Higher rates of light-saturated GPP were found during submerged periods compared to emerged periods in both habitats, but this difference …

Cryptographic coprocessors for embedded systems
… built around a small General Purpose Processor (GPP). If the GPP cannot meet the performance requirements for a certain operation, a coprocessor can be included in the design. The GPP can then offload the computationally intensive operation to the coprocessor; thus increasing the performance of …

Point Process Modelling of Objects in the Star Formation Complexes of the M33 Galaxy
In this thesis, Gibbs point process (GPP) models are constructed to study the spatial distribution of objects in the star formation complexes of the M33 galaxy. The GPP models circumvent the limitations of the two-point correlation function employed in the current astronomy literature by naturally …
