On Hajj Tourism: In Search of Piety and Identity in the New Order Indonesia
… the conceptual problems of stratification in a new comparative manner; rather, it focuses on the ways in which an Islamic identity has been transformed into a new configuration of life and into a dominant expressive culture such as through hajj-tourism."

Development of Mechanistic Flexible Pavement Design Concepts for the Heavyweight F-15 Aircraft (Airfield, Computer Design, Cbr, Algorithms)
A new configuration of the F-15 aircraft has been developed and is in use by the U.S. Air Force. This heavyweight F-15 has a 30-kip/355-psi wheel loading. A heavier-weight F-15 with 36-kip/395-psi wheel loading has been proposed for use. The F-15 will become the controlling aircraft for design of …

Effect of struts on aeroacoustics of axisymmetric supersonic inlets
… of a high bypass turbofan engine. Two inlet configurations were investigated in this study. The first configuration was the standard inlet design where the struts are located immediately upstream of the fan. The new configuration has the struts located 3.3 chord length upstream of the fan. …

Beyond Arrows: Energy Performance of a New, Naturally Ventilated Double-Skin Facade Configuration for a High-Rise Office Building in Chicago
… in high rise office buildings with DSF configuration: • A methodology for assessing the performance of naturally ventilated DSF buildings through an airflow modeling was developed by three-dimensional analysis using Fluent. Buoyancy, wind, and combined ventilation strategies for a …

The American church/state quagmire: A major cause and a proposed solution
… colonists had come to recognize an entirely new manner in which to organize a society. This new manner of organization gave sovereignty to the individual in two major societal systems: the political and the religious. The consequence of this was the recognition that churches and governments …

Performance and analysis of the plasma bipolar junction transistor: Control of the surface electrical properties
A new configuration of plasma bipolar junction transistor (PBJT) based on an epitaxial wafer has been designed and fabricated. Its electrical properties and the collector plasma densities are characterized using electrical and optical methods. Using this device as a platform, coupling of the …

An improved in situ sensing device for freshwater DOM characterization
… high DOC concentration and inner shielding. A new instrument is required to be designed to fulfil the objectives. Like the previous instrument, the new instrument still needs to measure the fluorescence and absorbance data to give an estimation of DOC concentration. There are three LEDs to …

Novel Reactors for Biological Treatment of High Strength Nitrogen and Carbon Wastewater
… The second objective was to modify the configuration of the foam-based anammox (MAX) in order to resolve some potential operational issues observed with PAX systems and to increase N removal efficiency. The third objective was focused on using a combination of nitritation-denitrification …

Competing constructions of children's participation in social care : analysing text and talk
… unevenly across them. I argue that there is a new configuration of welfare developing around children’s services where managerialism is dominant and children’s rights are collapsed into the customer discourse. Children’s voices are either absent or mediated by adult/professionals in most of the …

Design of microwave subsystems for radio astronomical receivers
… first project is focus on the development of a new configuration of broadband polarizer with very flat phase response in microtrip technology. The second project is a feasibility study on the optics of a 3mm SIS receiver in order to install it in the Gregorian focus of the Sardinia Radio …

Optimization of a fiber optic freshwater DOM sensing device
… for the Hammerhead optical fibers. Of the configurations tested, the narrowest spacing between excitation fiber and detector (0.076 inches from each fiber's tip to the center of the chamber) produced optimal results. This new configuration shortens the light path length and largely avoids …

Designing interfacial structures for selective electrocatalysis
… To achieve high 02 tolerance, we design a new configuration of electrocatalysis by employing a solid oxide-based mixed electron-proton conductor (MEPC) as a condensed membrane to segregate the catalyst and electrolyte while only transporting H-atom equivalents, thus blocking 02 and …

State aristocracy : resident senators and absent emperors in Late-Antique Rome, c. 320-400
… divisions within aristocratic society. New fiscal pressures, a rise in competitive expenditure and a narrowing of access to senior government posts had the consequence that many aristocrats could no longer participate in the competition for honour, wealth and offices. But not all …

Strain transducers for active control
… The second part of this thesis investigates a new configuration of the velocity feedback control system, which is composed of a piezoceramic actuator shaped as isosceles triangle with a velocity sensor at its tip. A fully coupled mobility model has been developed, which predicts the response of …
