Energy allocation and transmission scheduling for wireless and space communications
This thesis presents two innovations to geophysical inversion. The first provides a framework and an algorithm for combining linear deconvolution methods with geostatistical interpolation techniques. This allows for sparsely sampled data to aid in image deblurring problems, or, conversely, noisy …

Sublethal effects of an acetylcholinesterase-inhibiting pesticide on fitness-related traits in the western fence lizard (Sceloporous occidentalis)
… the effects of carbaryl on sprint performance energy acquisition, and energy allocation, traits which could have important implications for the animal's ability to avoid predators, capture prey, and grow and reproduce. I found that at the highest dose concentration, lizards experienced a …

FUNCTIONAL DISSECTION OF ADIPOKINETIC HORMONE PRODUCING CELLS
… understood. In Drosophila, the mobilization of energy is primarily controlled by the endocrine factor Adipokinetic Hormone (AKH). AKH function is critical for proper energy allocation under ad libitum conditions, and is particularly important for the physiological and behavioral response to …

DEEP REINFORCEMENT LEARNING FOR BUILDING ENERGY MANAGEMENT
Building energy management is an increasingly complex problem, both in terms of energy production and consumption, with the integration of renew- able energy and the ever-increasing needs of building residents. Multiple studies have shown that Deep Reinforcement Learning has great potential in …

Optimization of Near Field Coupling for Efficient Power Transfer Utilizing Multiple Coupling Structures
A rise in the need for dynamic energy allocation has been associated with the saturation of available portable wireless electronic devices. Currently, the methods for transmitting this energy efficiently have been limited to a number of options, including near field resonant magnetic coupling. …

Effects of enhanced winter nutrition and climatic variation on population performance of a large herbivore
Population performance hinges on optimal allocation of available energy by individuals to competing life-history traits. Life-history strategies of long-lived, iteroparous mammals often involve prioritizing energy allocation to adult survival over any single reproductive event, therefore maximizing …

Addressing misspecification in contextual optimization
… on these predictions. For example, consider an energy allocation problem when the energy cost in different areas is uncertain. Despite the absence of precise energy cost values at the time of problem-solving, machine learning models are employed to predict these costs, and the resulting …

Temperature Disparity Comparisons for Campus Heat Vulnerabilities
… both for human comfort as well as more efficient energy usage. In this research, climate modules were built and distributed across MIT’s campus to measure air tem- perature, ground temperature, humidity, pressure, and light every three minutes over 24 hours. The campus temperatures were compared …

Building an In-vitro Cell Model to Study Cellular Basis of Maturation Timing: A Proof of 3D Cell Culture Methodology in Atlantic Salmon Adipose Tissue
… in salmonid maturity, potentially by regulating energy allocation via regulating adipogenesis. In this thesis, a proof of principle study was implemented, where the feasibility of obtaining and maintaining a suspension 3D adipose tissue culture in Atlantic salmon (Salmo salar) was assessed. The …

A techno-economic and environmental assessment of hydroprocessed renewable distillate fuels
… and supporting utilities. Material and energy balances for electricity, carbon dioxide, and water requirements as well as economic costs were obtained from these models. A discounted-cash-flow-rate-of-return (DCFROR) economic model was used to evaluate minimum product values for diesel …

The energetic consequences of tail loss to juvenile lizards
… for predator deflection should allocate energy preferentially to tail growth at the expense of body growth. Relative linear tail growth (linear tail growth/linear body growth) and relative mass tail growth (tail mass growth/body mass growth) were measured for juveniles of two species of …

Molecular basis of life-history evolution: a tale of two insects
… on mortality (i.e. predation), and tradeoffs in energy allocation between competing physiological processes. Differences in life-history strategies have been well documented at the phenotypic level but their causal genetic mechanisms remain largely unknown. At the genetic level, tradeoffs between …

The effect of diet and parasite load on female phonotaxis in the Texas field cricket, Gryllus integer
… Such findings raise interesting questions about energy allocation and costs and risks of phonotaxis and mate choice in acoustic Orthoptera. These results are discussed in terms of sexual selection and female mate choice.

Power allocation in energy harvesting two-way relay systems
… are taken into account: a system with one energy harvesting (EH) relay node and a system with two EH transceivers and one EH relay node. Under these two assumptions, we study the optimization problem of harvesting energy allocation which maximizes the total data throughput of a wireless …

Measuring and Predicting Total Energy Expenditure Among Highly Active Humans in Natural Environments
<p>The current model for predicting human total energy expenditure (TEE), the Factorial Method, significantly underestimates actual TEE, particularly among highly active populations. In this study, the Allocation Model is presented for predicting TEE. Unlike the Factorial Method, the Allocation …
