The engineer relies greatly on Meteorological data for solar energy applications. In most case the available equipments indicate only the hourly or daily total irradiance on a flat horizontal surface. However, a more basic or fundamental information may also be necessary especially when application call for a knowledge of the apparent motion of the sun relative to an observer on earth. In such cases, the controlling equations are often stated without proof. The present submission synthesizes this aspect of spherical geometry in heavenly kinematics in form concise enough for engineering and meteorological applications. The final expressions will be familiar to workers in meteorology and to engineers involved in solar energy instrumentation and utilization on ground. The analyses are educational adaptations of engineering mechanics to this growing field of heliotechnoloy. NOTATION [1] = solar altitude angle = surface tilt angle, towards Equator +, away from Equator = solar azimuth angle, clockwise from North = solar declination angle , i = incidence angle (on surface) = latitude = solar hour angle, solar noon = 0.00, afternoon +ve L = longitude t = time (hours)
Multiresolution grayscale and rotation invariant texture classification with local binary patterns
 IEEE TRANSACTIONS ON PATTERN ANALYSIS AND MACHINE INTELLIGENCE
, 2002
"... This paper presents a theoretically very simple, yet efficient, multiresolution approach to grayscale and rotation invariant texture classification based on local binary patterns and nonparametric discrimination of sample and prototype distributions. The method is based on recognizing that certain ..."

;uniform" patterns for any quantization of the angular space and for any spatial resolution and presents a method for combining multiple operators for multiresolution analysis. The proposed approach is very robust in terms of grayscale variations since the operator is, by definition, invariant against any monotonic

Angular momentum: an approach to combinatorial spacetime
 Living Reviews in Relativity http://www.livingreviews.org/lrr20085 Carlo Rovelli
, 1971
"... I want to describe an idea which is related to other things that were suggested in the colloquium, though my approach will be quite different. The basic theme of these suggestions have been to try to get rid of the continuum and build up physical theory from discreteness. The most obvious place in w ..."

in which the continuum comes into physics is the structure of spacetime. But, apparently independently of this, there is also another place in which the continuum is built into present physical theory. This is in quantum theory, where there is the superposition law: if you have two states, you’re supposed

"... From a signal processing perspective, we examine the main factors defining the visual quality of autostereoscopic 3D displays, which are beginning to reproduce the plenoptic function with increasing accuracy. We propose using intuitive visual tools and raytracing simulations to gain insight into t ..."

With this approach we are able to intuitively demonstrate some basic limitations of displays using anisotropic diffusers or lens arrays. Furthermore, we propose new schemes for improved
