Calibrating a Latent Order Book Model to Market Data
… Monte-Carlo ABC (PMC-ABC) as well as a Black-box approach using the Nelder-Mead algorithm. We show that in the diffusion limit, the master equation becomes the LOB reaction-diffusion PDE and certain free-parameters are recoverable with the iterative calibration techniques.

Synthesis of electric networks interconnecting PZT actuators to efficiently damp mechanical vibrations
… circuit analog to the Euler beam.We will approach this synthesis problem following the black box approach to mechanical systems, studied by many engineers and scientists during the 1940's in an attempt to design analog computers.It will be shown that it is possible to obtain a quick energy …

Investigation in modeling a load-sensing pump using dynamic neural unit based dynamic neural networks
… creating complex computer model is the use of “black box” approach to create an approximation of the system behaviour by analyzing input/output relationships. That means the details of the physical phenomena are not so much of concern in the “black box” approach. Neural network can be used to …

A genetic approach to management education and the science of teaching
… students in the transmission of knowledge. A "black-box" approach to the processes of learning and problem solving is developed. From this approach evolved five essential phases to designing a protocol on how management students should learn what we (teachers) want them to learn. A case is …

Multiple-implementation testing of supervised learning software
… test-oracle issue, this thesis presents a novel black-box approach of multiple-implementation testing for supervised learning software. The insight underlying the approach is that there can be multiple implementations (independently written) for a supervised learning algorithm, and majority of …

Modeling and Control of Voltage-Controlling Converters for Enhanced Operation of Multi-Source Power Systems
… and systems. The dissertation will start with a "black box" approach to modeling of three-phase power electronics converters, introducing a method to remove source and load dynamics from in-situ measured terminated frequency responses. It will be then shown how converter, itself, can perform an …

Trojan Detection in Large Language Models of Code
… evaluated two trojan detection techniques – a black-box approach, OSeqL, for detecting input triggers to trojaned code models, and a white-box approach for detecting trojan signatures from such models. Finally, we evaluated the effects of quantization on the trojan behaviour of models. Our …

Mapping numerical software onto distributed memory parallel systems
… dependencies. The use of tools rather than the black box approach removes the handicaps associated with using heuristic methods, if any relevant heuristic methods exist.

Secure and high-performance big-data systems in the cloud
… search overhead. The key idea is to use a white-box approach to search for the theoretically best partitioning and then use a black-box approach to verify the effectiveness of such partitioning. The proposed technique, called Auto-pipelining, is implemented on IBM Stream S. Third, I proposed …

Terminal Behavioral Modeling of Electric Machines for Real-time Emulation and System-level Analysis
… system. In this work, the application of the black box approach study of the power converters has been expanded to the electrical machines. Using this modeling method, it is possible of have accurate behavior of electrical and mechanical terminals of the machine without the detailed …

The Role of Mirror Errors in Solar Energy Conversion
… that relies on reflection. Three theoretical approaches are taken. Taking a “black box” approach to an open cycle engine which converts radiation to work, basic relations are derived which express the work output as a function of entropy carried by the radiation. When radiation is reflected …

An Ecological Approach to Feed Management in Fish Rearing Ponds
… Catfish culturists have historically used a “black box” approach to feed management by only quantifying the effects of varied manufactured feed subsidies on mean fish size and yield at harvest. Alternatively, I sought to improve fish production efficiency and reliability by quantifying the …

Bayesian bilevel optimization
… improving bilevel optimization through several approaches developed during research. Bilevel optimization problems consist of upper-level and lower-level optimization problems connected hierarchically. Upper-level and lower-level problems are also referred to as the leader and the follower …

Design and evaluation of real-time Voice-Over-IP (VOIP) systems with high perceptual conversational quality
… under repeatable and fair conditions using a black-box approach. We have applied this methodology and test-bed on four commonly used VoIP systems; Skype, Google-Talk, Windows Live and Yahoo Messenger. The results show that different systems operate differently in coping with network …

The feasibility of a commercial-scale recirculating aquaculture system integrating sea urchins (Tripneustes gratilla) and seaweed (Ulva)
… emissions and its complexity, an empirical ‘black box' approach using regression models was used for predicting TAN concentrations in T. gratilla effluent. Training and validation data were acquired from an extensive trial where water samples were collected from urchin systems with different …
