Quick calculation method for fluid flow through duct systems

Conditions for subsonic compressible flow through duct systems are quickly and easily calculated using compact series of curves showing dimensionless parametric functions of Mach number and specific heat ratio. Method is directly applicable to analysis and design of compressible flow systems in industrial fields or processes

Photography and the Work-for-Hire Doctrine

Photography has enjoyed a unique niche in the history of copyright, especially in the context of the work-for-hire doctrine. In this article, I intend to trace that history, beginning with the Supreme Court case decided over 100 years ago which first extended copyright protection to photographs. I will then examine the treatment photography received under the 1909 Act and the 1976 Act and judicial interpretations of this legislation. Finally, I will look at recent legislative action in the states of New York and California and its impact on the workfor- hire doctrine as it is applied to photography, and recommend a statutory addition for Texas

Legal Barriers and Opportunities to Developing Business Partnerships Between Fisheries and Tourism

Tourism is one of the largest contributors to Maine’s economy, contributing billions of dollars annually. The primary draw for many tourists visiting Maine is the vast outdoor recreation that Maine affords its visitors. This paper examines the legal issues regarding the possibility of commercial fishing vessels carrying passengers for hire, as well as aquaculture farms opening themselves up for visits from tourists

Radiative property investigation

A detailed formulation of radiative heat transfer problems involving the use of bidirectional reflectance is discussed. Except for very simple systems this formulation is very intricate. For this reason and the fact that bidirectional data are scarce, such a formulation is not in common use. However, with the development of the digital computer there have been numerical methods developed for detailed radiative investigations using the bidirectional reflectance. Since computations using bidirectional reflectance are coming into use for spacecraft radiative studies, it is necessary to have reflectance data on the materials involved. Materials that are frequently studied are coatings which are used in controlling the thermal environment of spacecrafts. This study is primarily concerned with the bidirectional reflectance of zinc oxide which is one constituent commonly used for coatings

Determination of particle size using measurement of scatter

A literature search was conducted to determine the state of the art particle size measurement by the light scatter technique. This technique may involve diffraction pattern analysis, location of minima and maxima in angular dependence of scattered light, magnitude of intensity verses angle, forward lobe scattered intensity ratio using two small angles, forward scatter in a small cone, and total scatter. Some of the more modern recordings and detection systems are video, holographic, and systems using optical processing
