A Day in the Life of a Float Plane Charter Pilot

Ever taken a float plane trip or wanted to? Learn what it’s like to be a float plane pilot doing charter work in the Puget Sound area of Washington state. Hear this light-heated, informal, presentation by someone who has done all this for “fun and profit”

Examining the Value of a Bachelor\u27s Degree for Helicopter Pilots

Traditionally, a bachelor’s degree has never been a qualification requirement for entry-level helicopter pilots obtaining employment or for even becoming entirely successful helicopter pilots in the industry.As helicopter companies grow into larger corporate entities, a bachelor’s degree is beginning to appear as a desirable qualification on some helicopter pilot job advertisements.Currently, only corporate helicopter operators, aircraft manufacturers, and some branches of the military actually require their helicopter pilots to hold 4-year degrees

Off-Shore Helicopter Operations

This case study research project is based on a foreign oil company desiring to set up and provide helicopter transportation to and from oil rigs in the gulf. Theresearch resulted in three potential options: Purchase a carrier with a current operating certificate Start a new company Contract an existing operator to perform the operations

The Quantum McKay Correspondence for polyhedral singularities

Let G be a polyhedral group, namely a finite subgroup of SO(3). Nakamura's G-Hilbert scheme provides a preferred Calabi-Yau resolution Y of the polyhedral singularity C^3/G. The classical McKay correspondence describes the classical geometry of Y in terms of the representation theory of G. In this paper we describe the quantum geometry of Y in terms of R, an ADE root system associated to G. Namely, we give an explicit formula for the Gromov-Witten partition function of Y as a product over the positive roots of R. In terms of counts of BPS states (Gopakumar-Vafa invariants), our result can be stated as a correspondence: each positive root of R corresponds to one half of a genus zero BPS state. As an application, we use the crepant resolution conjecture to provide a full prediction for the orbifold Gromov-Witten invariants of [C^3/G].Comment: Introduction rewritten. Issue regarding non-uniqueness of conifold resolution clarified. Version to appear in Inventione

A numerical ocean circulation model of the Norwegian and Greenland Seas

The dynamics and thermodynamics of the Norwegian and Greenland Seas are investigated using a three-dimensional primitive equation ocean circulation model. The horizontal resolution of the model is 1° in the zonal direction and 0.5° in the meridional direction. The vertical structure is described by 15 levels. The model is driven by both annual mean and seasonally varying wind and thermohaline forcing. The connections of the Norwegian and Greenland Seas with the North Atlantic and Arctic Ocean are modelled with an open boundary condition. The simulated currents are in reasonable agreement with the observed circulation

Orbifold Quantum Riemann-Roch, Lefschetz and Serre

Given a vector bundle $F$ on a smooth Deligne-Mumford stack \X and an invertible multiplicative characteristic class \bc, we define the orbifold Gromov-Witten invariants of \X twisted by $F$ and \bc. We prove a "quantum Riemann-Roch theorem" which expresses the generating function of the twisted invariants in terms of the generating function of the untwisted invariants. A Quantum Lefschetz Hyperplane Theorem is derived from this by specializing to genus zero. As an application, we determine the relationship between genus-0 orbifold Gromov-Witten invariants of \X and that of a complete intersection. This provides a way to verify mirror symmetry predictions for complete intersection orbifolds.Comment: major revision: numerous changes made, mistakes corrected, some new materials adde
