Extending the Birkhoff-von Neumann switching strategy to multicast switching
The Birkhoff-von Neumann (BVN) strategy for offline switching does not support multicast, as it considers only permutation-based switch configurations. This thesis extends the BVN strategy to multicast switching. Using a graph theoretic model, we show that the capacity region for a traffic pattern …

Design of Switching Strategy for Adaptive Cruise Control Under String Stability Constraints
… of ACC controller often involves the design of a switching logic that decides where and when to switch between the two modes in order to ameliorate driving comfort, mitigate the chance of a potential collision with the preceding vehicle while reduce long-distance driving load from the driver. In …

Analysis and Design of Hybrid Control Systems
… designs in separate regions together with a switching strategy. Dynamics are not well defined if the control design methods lead to fast mode switching. The dynamics depend on the salient features of the implementation of the mode switches. A theorem for the stability of second order …

Development of Functional DNA -Based Sensors and Investigations Into Their Mechanism
… in Chapter 5. Chapter 6 describes the structure-switching strategy to isolate DNA aptamers specific for endotoxins. It is anticipated that the results obtained from the current study and future characterizations will lead to the development of functional DNA sensors for endotoxins.

Control of Switched Reluctance Motors Considering Mutual Inductance
… current or flux linkage ripple, a unipolar switching strategy is proposed. The unipolar switching strategy effectively doubles the switching frequency without increasing the actual switching frequency of the switches. This contributes to the mitigation of current or flux linkage ripple and …

Foraging memory: Retrieving words from one and from two semantic categories
… mental load of executing an autonomous switching strategy (executive-decision cost); and sub-optimal allocation of time between categories. Experiment 1 tested whether switching between categories leads to a switch cost and/or time-out benefit by having subjects produce items from a …

Real-time optimal control of autonomous switched systems
… systems are open-loop in nature. Therefore, the switching times of the system can not be adjusted or adapted when the system parameters or the operational environments change. This thesis aims to close this loop, and apply adaptations to the optimal switching strategy based on new information …

Evaluation of the potential impact of electrochromic windows on the energy performance of commercial buildings
… the effect of several driving variables for switching on the cooling load of an existing large commercial building. The present capabilities of the DOE program are expanded using the Functional Values approach in order to study the effect of the electrochromic glazing switching time for the …

Soft-Switching, Interleaved Inverter for High Density Applications
… the latest transistor technology to push switching frequency to shrink passive filter size. Furthermore, while high efficiency is an important thermal handling strategy, it must be weighed against increases in component size. Google's Little Box Challenge shone light on these challenges in …

A discrete event simulation model for unstructured supervisory control of unmanned vehicles
… and operator team structure, and operator switching strategy. The accuracy and robustness of the MO-MUVDES model were measured by a two-stage validation process using data from a human-in-the-loop supervisory control experiment, and a Monte Carlo simulation. The first stage of the …

A comparison of human performance on computer text editing tasks using windowed and non-windowed strategies
… three strategies, note-taking, memorizing, or switching between files, were included to allow comparisons in terms of working memory and number and types of responses executed. The tasks required subjects to locate information from a supplementary file and type it into a main file. The three …
