Title: Path Curves and Plant Buds: an Introduction to the Work of Lawrence Edwards
Authors: Almon, Clopper
Abstract: Lawrence Edwards has shown that many flowering plants have buds with an outline in the form of a path curve, the curve that a point follows under repeated projective transformation of the plane into itself. Edwards, however, did not give a formula for these curves nor did he fit the curves by the standard method of least squares. This paper gives an elementary exposition of the method used by Edwards, shows its relation to projective geometry, and then uses homogeneous coordinates, linear differential equations and characteristic values and vectors of a matrix to derive the formula for path curves. This formula is then used to fit path curves by least squares to data provided by Edwards for the buds of 150 plants. Most buds are fit very closely.1979-07-01T00:00:00ZVelia and the Cilento, an Introduction

Title: Velia and the Cilento, an Introduction
Authors: Almon, Clopper
Abstract: Material for students in a Study Abroad course beginning in Ascea, near Velia, in Southern Italy. It begins with the geological evolution of the Mediterranean and moves on to the prehistory of the area, the coming of the Greeks, the settlement of Elea = Velia, the Eleatic philosophers, the area in Roman times, and history up to the present, with special attention to the Consorzio Velia, which provides water to the area.2013-01-01T00:00:00ZScientific Programming with Borland C++ Builder and Codegear's Turbo C++

Title: A Brief Guide to C and C++ for Fortran or Basic Programmers
Authors: Almon, Clopper
Abstract: This paper introduces C and C++ programming for learners who already have some experience in another language such as Fortran or Basic. It explains basic syntax, dynamic space allocation, structures, classes, constructors and destructors, and overloading of operators. All concepts are illustrated with working programs.1999-01-01T00:00:00Z
