Hybrid Ventilation Flows
Hybrid ventilation is likely to become an increasingly important element of low-energy building design, as it is often perceived to embody both the energy efficiency of natural ventilation, and the control and reliability of mechanical ventilation. However, at the outset of this work there was …

Hybrid body craft
… and modification. As its name implies, Hybrid Body Craft (HBC) is an attempt to hybridize technology with body craft materials, form factors, and application rituals, with the intention of integrating existing cultural practices with new technological functions that have no prior …

Hybrid Steel Frames
… introduces two new structural steel systems: hybrid Buckling Restrained Braced Frames (BRBF) and hybrid steel Moment Frames (MF). The "hybrid" term for the BRBF system comes from the use of different steel material including carbon steel (A36), high-performance steel (HPS) and low yield point …

Hybrid wireless broadband networks
A hybrid system is an integration of two or more different systems, particularly in this thesis referring to wireless broadband networks. However, to provide end-to-end quality of service (QoS) in a hybrid system is a challenging task due to different protocol in each system. In this thesis, we aim …

Inorganic/organic hybrid polymers
… and characterise a range of inorganic/organic hybrid polymers containing pendant vinyl groups and to study their uses as possible fire retardants. The work consisted of several parallel strands: the synthesis of organically modified silicas; the preparation of vinyl containing silsesquioxanes …

Hybrid cloud security certification
In this report, I introduce a hybrid approach for certifying security properties of cloud services that combines monitoring and testing data. This report argues about the need for hybrid certification and examines the basic characteristics of hybrid certification models. The certification of cloud …

Hybrid plasma-semiconductor devices
A hybrid plasma-semiconductor phototransistor has been realized by substituting a plasma for the collector of an npn bipolar junction transistor. Designated as the plasma bipolar junction transistor (PBJT), this optoelectronic device relies on the correspondence between the properties of a low …

Hybrid bio-templated catalysts
… as a biological scaffold and template to form hybrid Rh-Ni@CeO₂ nanowires. These composite materials have exceptionally high thermal stability, showing a greater than 8 th order growth when made as isolated nanoparticles, and over 2 0 th order growth when assembled into nanowires, compared to …

Hybrid and multifield inflation
… in two classes of inflationary models: hybrid inflation and multifield inflation with non-minimal coupling to gravity. In the case of hybrid inflation, we developed a new method of treating these perturbations that does not rely on a classical trajectory for the fields. A characteristic …

Precision hybrid pipelined ADC
… ADC operating at up to 100MS/s. A two-phase hybrid ZCBC operation is used to improve the power-linearity tradeoff of the A/D conversion. The first phase approximates the final output value, while the second phase allows the output to settle to its accurate value. Since the output is allowed …

Vertical Axis Hybrid Wind Turbine
… the potential and practicality of vertical axis hybrid wind turbines (VAHWTs) for sustainable electricity generation and investigate the self-starting issue of VAWT. The development of sustainable energy sources has become increasingly critical in recent years because of growing worries about …

Hybrid machine modelling and control.
… machine, the second one is referred to as a hybrid machine. The focus of interest here is on the hybrid machine. One anticipated benefit, the second would have over the first, is that the size of the servo-motor power requirement should come down. In order to explore the idea an experimental …

Hybrid Methods for Feature Selection
… set of features. In this study, we propose two hybrid methods for feature selection. The best features are selected through either the hybrid methods or existing feature selection methods. Next, the reduced dataset is used to build classification models using five classifiers. The classification …

Hybrid Control For Aerospace Systems
Hybrid dynamical systems are dynamical systems in which continuous and discrete evolutions coexist and interact. Their twofold nature makes them particularly powerful for both describing and synthesizing complex dynamical behaviors. In this work we exploit this capability for designing innovative …
