We describe the reflection model of Oberon-2, a language in the tradition of Pascal and Modula-2. It provides run-time information about the structure of variables, types and procedures and allows the programmer to manipulate the values of variables. The special aspect of the Oberon-2 reflection model is that metainformation is not obtained via metaclasses. It is rather organized as structured ...

The separation of diffuse and specular reflection components, or equivalently specularity removal, is required in the fields of computer vision, object recognition and image synthesis. This paper proposes a simple and effective method to separate reflections in a color image based on the error analysis of chromaticity and appropriate selection of body color for each pixel. By solving the least-...

Architectural reflection is the computation performed by a software system about its own software architecture. Building on previous research and on practical experience in industrial projects, in this paper we expand the approach and show a practical (albeit very simple) example of application of architectural reflection. The example shows how one can express, thanks to reflection, both functi...

Placement of a scatter cone at the center of the secondary of a Cassegrain telescope greatly reduces Nareissus reflection. To calculate the remaining Narcissus reflection, a time-consuming physical optics code/such as GRASP8 is often used to model the effects of reflection and diffraction. Fortunately, the Cassegrain geometry is sufficiently simple that a combination of theoretical analysis and...

Reflection is a design principle that allows a system to have a representation of itself in the manner that makes it easy to adapt the system to a changing environment. It has now matured to the point where it is used to address real-world problems in various areas. This principle has been also identified as a pattern of software architecture (PoSA) [1]. This paper presents a non-software examp...

An object-oriented language that permits changing the behavior of a class or of a single object is said to support computational reflection. Existing reflective facilities in object-oriented languages are either complex, type unsafe, or have a large performance penalty. We propose a simple, easy-to-understand, and statically typed model that captures much of the functionalities of other reflect...

Optical properties of doped silicon wafers have been measured by means of terahertz time domain reflection spectroscopy. A method is proposed to obtain the relative phase by reflection accurately. By using this method, the relative phase is obtained within an error of less than 10 mrad at 1 THz. The experimentally obtained complex conductivity of relatively high-doped silicon (r 50.136 V cm) in...

Surface-reflection component is blocked by the analyzer A simple technique of measuring a reflective TN liquid crystal (LC) cell gap using a laser is described. It utilizes a very unique property of strong input-polarization-angle dependence of the reflective LCs, which is not observed in the conventional transmissive LCs. This technique eliminates the surface-reflection problem which can be en...

This is a survey article on the theory of finite complex reflection groups. No proofs are given but numerous references are included. This chapter is concerned with the theory of finite reflection groups, that is, finite groups generated by reflections in a real or complex vector space. This is a rich theory, both for intrinsic reasons and as far as applications in other mathematical areas or m...

The healthcare professional in our age needs to PERFORM in complex and challenging healthcare environments. The importance of reflection, reflective practice and teaching and training to develop a reflective practitioner is frequently established in the literature. In fact, recent research on pedagogy stresses the importance of establishing a link between reflective learning and reflective prac...
