Final proposal for encoding the Bassa Vah script in the SMP of the UCS

This is a proposal to encode the Bassa Vah script in the international character encoding standard Unicode. This script was published in Unicode Standard version 7.0 in June 2014. The Bassa Vah script was used to write the Bassa language of Liberia

Proposal to encode modern Bamum in the BMP of the UCS

This is a proposal to encode the modern Bamum script in the international character encoding standard Unicode. The script was published in Unicode Standard version 5.2 in October 2009. The script was developed between 1896 and 1910, primarily by King Ibrahim Njoya of the Bamum Kingdom. The script went through six stages; the modern version, contained in this proposal, is a simplified version of the historic script (which was separately proposed in and published in Unicode 6.0)

Application of formal optimization techniques in thermal/structural design of a heat-pipe-cooled panel for a hypersonic vehicle

Nonlinear mathematical programming methods are used to design a radiantly cooled and heat-pipe-cooled panel for a Mach 6.7 transport. The cooled portion of the panel is a hybrid heat-pipe/actively cooled design which uses heat pipes to transport the absorbed heat to the ends of the panel where it is removed by active cooling. The panels are optimized for minimum mass and to satisfy a set of heat-pipe, structural, geometric, and minimum-gage constraints. Two panel concepts are investigated: cylindrical heat pipes embedded in a honeycomb core and an integrated design which uses a web-core heat-pipe sandwich concept. The latter was lighter and resulted in a design which was less than 10 percent heavier than an all actively cooled concept. The heat-pipe concept, however, is redundant and can sustain a single-point failure, whereas the actively cooled concept cannot. An additional study was performed to determine the optimum number of coolant manifolds per panel for a minimum-mass design

A fluorescing spot on the temple: a helpful reminder for a detailed history and physical exam

We discuss a woman with a history of non-melanoma skin cancer who presented with a new erythematous macule on her right temple. On examination with Wood lamp the well-demarcated macule fluoresced pink making neoplasm unlikely. Further history and physical examination suggested an inadvertent ink stain and the patient was spared a biopsy highlighting the importance of eliciting a good history and performing a detailed physical examination with additional tools such as a Wood lamp when necessary

Two leaf beetles new to Florida (Coleoptera: Chrysomelidae)

Specimens recently submitted to the first author for identification turned out to represent two species of leaf beetles previously unknown from Florida, one of which is new to the eastern United States and the other new to the continental United States

Integrated aerodynamic/dynamic optimization of helicopter rotor blades

An integrated aerodynamic/dynamic optimization procedure is used to minimize blade weight and 4 per rev vertical hub shear for a rotor blade in forward flight. The coupling of aerodynamics and dynamics is accomplished through the inclusion of airloads which vary with the design variables during the optimization process. Both single and multiple objective functions are used in the optimization formulation. The Global Criteria Approach is used to formulate the multiple objective optimization and results are compared with those obtained by using single objective function formulations. Constraints are imposed on natural frequencies, autorotational inertia, and centrifugal stress. The program CAMRAD is used for the blade aerodynamic and dynamic analyses, and the program CONMIN is used for the optimization. Since the spanwise and the azimuthal variations of loading are responsible for most rotor vibration and noise, the vertical airload distributions on the blade, before and after optimization, are compared. The total power required by the rotor to produce the same amount of thrust for a given area is also calculated before and after optimization. Results indicate that integrated optimization can significantly reduce the blade weight, the hub shear and the amplitude of the vertical airload distributions on the blade and the total power required by the rotor
