Optimizing communication bottlenecks in multiprocessor operating system kernels
… dissertation focuses on optimizing communication bottlenecks caused by update-heavy workloads, where a data structure is frequently updated but rarely read. Such data structures are commonly used for operating system kernel bookkeeping, such as LRU lists, reverse maps in virtual memory, and file …

Addressing performance bottlenecks for top-down engineered nanowire transistors
… investigated in order to address the performance bottlenecks and to further enhance the performance of semiconductor nanowire devices. In this work, Ge rich nanowire transistors are demonstrated with metal gate/high-k gate stack. Using the pattern size dependent Ge condensation technique, lateral …

Identifying Bottlenecks through Process Consistency in High-Capacity Automated Manufacturing
This thesis explores the identification of bottlenecks in automated assembly lines through process consistency. In general, large automated assembly lines have processes grouped together that have a huge affect on one another. They can only operate as fast as the slowest process (the bottleneck) in …

Theoretical Investigation of Biological Networks Coupled via Bottlenecks in Enzymatic Processing
… of available enzymes permits the formation of bottlenecks which drastically affect molecular dynamics within cells. These effects potentially afford cell behaviors that in part explain the impressive robustness of life to constantly fluctuating environments.

A Comparison of CORSIM and INTEGRATION for the Modeling of Stationary Bottlenecks
Though comparisons of simulation models have been conducted, few investigations have examined in detail the logical differences between models. If the output measures of effectiveness are to be interpreted correctly, it is important that the analyst understand some of the underlying logic and …

Genetic effects of persistent population bottlenecks on long-lived organisms with overlapping generations
… of individuals. The genetic consequences of bottlenecks include increased inbreeding, accelerated rate of random genetic drift, and decreased genetic diversity and adaptive evolution potential. These effects increase extinction probability and raise great concerns in conservation. Most …

Automating Video Analysis for Marine and Behavioural Research: Deep Learning Solutions to Analytical Bottlenecks
Technological advances have dramatically increased marine data collection capacity, shifting the primary challenge in ocean science from data acquisition to data processing. An 'analytical bottleneck' now limits the extraction of ecological insight from information-rich datasets such as video …

Elevated temperatures create bottlenecks in the life history of bull kelp (Nereocystis luetkeana, Phaeophyceae)
… temperatures. These findings reveal critical bottlenecks in bull kelp maturation and recruitment, with serious implications for population persistence and ecosystem resilience in a warming ocean.

Tackling the Bottlenecks in Translational Nanomedicine: Towards Precision in Size Control and Facile Nanoformulation
… of nanomedicine is impeded by several bottlenecks that include low targeting efficiency, imprecise size control, lack of scalable fabrication, rigorous stability requirement, and complicated manufacturing process. The common focus of the studies here is to address these bottlenecks by …

Absorptive capacity to finance HIV/AIDS treatment in South Africa: Where are the bottlenecks?
… framework of absorptive capacity and related bottlenecks in the context of funding for HIV/AIDS treatment in the public health sector. It identifies five major areas where bottlenecks may arise: financial, human, infrastructural, institutional (within the health system) and structural (outside …

A Study of the Capacity Drop Phenomenon at Time-Dependent and Time-Independent Bottlenecks
… drop can be introduced at time-independent bottlenecks (e.g. freeways) as well as time-dependent bottlenecks (e.g. signalized intersections). While to the author's knowledge no one has attempted to link these phenomena, the research presented in this thesis serves as a first step in doing …

Blended Learning and Bottlenecks in the California State University System: An Empirical Look at the Importance of Demographic and Performance Analytics
… Office and Board of Trustees are investigating "bottlenecks," defined as anything limiting students' ability to graduate in a timely manner. Blended learning, a pedagogy combining face-to-face and computer-mediated instruction, presents a potential solution to alleviate overcrowding and …
