A CLIPS-based tool for aircraft pilot-vehicle interface design
The Pilot-Vehicle Interface of modern aircraft is the cognitive, sensory, and psychomotor link between the pilot, the avionics modules, and all other systems on board the aircraft. To assist pilot-vehicle interface designers, a C Language Integrated Production System (CLIPS) based tool was developed that allows design information to be stored in a table that can be modified by rules representing design knowledge. Developed for the Apple Macintosh, the tool allows users without any CLIPS programming experience to form simple rules using a point and click interface
Classifying and monitoring water quality by use of satellite imagery
A technique in which LANDSAT measurements from very clear lakes are subtracted from measurements from other lakes in order to remove atmospheric and surface noise effects to obtain a residual signal dependent only on the material suspended in the water is described. This residual signal is used by the Multispectral Data Analysis System as a basis for producing color categorized imagery showing lakes by type and concentration of suspended material. Several hundred lakes in the Madison and Spooner, Wisconsin area were categorized for tannin or non-tannin waters and for the degree of algae, silt, weeds, and bottom effects
Sensitivity of mixing layers to three-dimensional forcing
It is well known that turbulent mixing layers are dominated by large scale, fairly coherent structures, and that these structures are related to the stability characteristics of the flow. These facts have led researchers to attempt controlling such flows by selectively forcing certain unstable modes, which can in addition have the effect of suppressing other modes. Much of the work on controlling the mixing layer has relied on forcing 2-D instabilities. The results of forcing 3-D instabilities are addressed. The objectives of the work are twofold: to understand how a mixing layer responds to 3-D perturbations, and to test the validity of an amplitude expansion in predicting the mixing layer development. The amplitude expansion could be very useful in understanding and predicting the 3-D response of the flow to a variety of initial conditions

Equation of state of classical Coulomb plasma mixtures
We develop analytic approximations of thermodynamic functions of fully
ionized nonideal electron-ion plasma mixtures. In the regime of strong Coulomb
coupling, we use our previously developed analytic approximations for the free
energy of one-component plasmas with rigid and polarizable electron background
and apply the linear mixing rule (LMR). Other thermodynamic functions are
obtained through analytic derivation of this free energy. In order to obtain an
analytic approximation for the intermediate coupling and transition to the
Debye-Hueckel limit, we perform hypernetted-chain calculations of the free
energy, internal energy, and pressure for mixtures of different ion species and
introduce a correction to the LMR, which allows a smooth transition from strong
to weak Coulomb coupling in agreement with the numerical results.Comment: 6 pages, 7 figures; Phys. Rev. E. In v.2 after proofreading, minor
