X-Ray methods
This article is about the nature, production, and uses of the radiation. For the method of imaging, see Radiography. For the medical specialty, see Radiology. For other meanings, see X-ray (disambiguation). Not to be confused with X-wave or X-band. X-rays are part of the electromagnetic spectrum, with wavelengths shorter than visible light. Different applications use different parts of the X-ray spectrum. X-ray X-ray of human lungs An X-ray, or X-radiation, is a penetrating form of high-energy electromagnetic radiation. Most X-rays have a wavelength ranging from 10 picometres to 10 nanometres, corresponding to frequencies in the range 30 petahertz to 30 exahertz (3×1015 Hz to 3×1018 Hz) and energies in the range 124 eV to 124 keV. X-ray wavelengths are shorter than those of UV rays and typically longer than those of gamma rays. In many languages, X-radiation is referred to as Röntgen radiation, after the German scientist Wilhelm Röntgen, who discovered it on November 8, 1895.[1] He named it X-radiation to signify an unknown type of radiation.[2] Spellings of X-ray(s) in English include the variants x-ray(s), xray(s), and X ray(s
stability analysis
Slope stability analysis is a static or dynamic, analytical or empirical method to evaluate the stability of earth and rock-fill dams, embankments, excavated slopes, and natural slopes in soil and rock. Slope stability refers to the condition of inclined soil or rock slopes to withstand or undergo movement. The stability condition of slopes is a subject of study and research in soil mechanics, geotechnical engineering and engineering geology. Analyses are generally aimed at understanding the causes of an occurred slope failure, or the factors that can potentially trigger a slope movement, resulting in a landslide, as well as at preventing the initiation of such movement, slowing it down or arresting it through mitigation countermeasures. The stability of a slope is essentially controlled by the ratio between the available shear strength and the acting shear stress, which can be expressed in terms of a safety factor if these quantities are integrated over a potential (or actual) sliding surface. A slope can be globally stable if the safety factor, computed along any potential sliding surface running from the top of the slope to its toe, is always larger than 1. The smallest value of the safety factor will be taken as representing the global stability condition of the slope. Similarly, a slope can be locally stable if a safety factor larger than 1 is computed along any potential sliding surface running through a limited portion of the slope (for instance only within its toe). Values of the global or local safety factors close to 1 (typically comprised between 1 and 1.3, depending on regulations) indicate marginally stable slopes that require attention, monitoring and/or an engineering intervention (slope stabilization) to increase the safety factor and reduce the probability of a slope movement.
micro-reactor
A microreactor or microstructured reactor or microchannel reactor is a device in which chemical reactions take place in a confinement with typical lateral dimensions below 1 mm; the most typical form of such confinement are microchannels.[1] Microreactors are studied in the field of micro process engineering, together with other devices (such as micro heat exchangers) in which physical processes occur. The microreactor is usually a continuous flow reactor[2][3] (contrast with/to a batch reactor). Microreactors offer many advantages over conventional scale reactors, including vast improvements in energy efficiency, reaction speed and yield, safety, reliability, scalability, on-site/on-demand production, and a much finer degree of process control
crystallization
Qualitative methods illuminate both the ordinary within the worlds of fabulous people and events and also the fabulous elements of ordinary, mundane lives. How to represent the truths we generate remains an open question. The interpretive turn in social sciences, education, and allied health fields inspired a wide variety of creative forms of representation of qualitative findings, including narratives, poetry, personal essays, performances, and mixed-genre/ multimedia texts as alternatives to the hegemony of traditional social scientific research reporting strategies that pervaded the academy (e.g., Denzin, 1997). At the same time, scholars updated traditionally positivist or postpositivist approaches to grounded theory (inductive, constant comparative) analysis (Glaser & Strauss, 1967; Strauss & Corbin, 1990) by bringing them around the interpretive turn and situating them in social constructivist (Charmaz, 2000), ONE 1 01-Ellingson-45623:01-Ellingson-45623 7/2/2008 2:50 PM Page 1 postmodern (Clarke, 2005), and social justice/activist (Charmaz, 2005) frameworks. In both inductive analytic (e.g., grounded theory) and more artistic approaches to qualitative research, researchers abandoned claims of objectivity in favor of focusing on the situated researcher and the social construction of meaning
particle dynamics
This chapter discusses force and motion in relation to particle dynamics. Any influence that can cause a body to accelerate is called a force. The study of the motion of particles in terms of the forces associated with that motion is called particle dynamics. A body has a constant velocity unless it is acted on by a net force. Many individual forces may act on a body, but the resultant or net force must be equal to zero if the body is not to accelerate. The assertion that a body on which there is no net force experiences no acceleration implies that a moving body will maintain a constant velocity forever unless acted on by a net force. Newton's first law, however, does not apply to all reference frames, the coordinate systems. The application of Newton's laws usually means solving dynamics problems, which are commonly stated as word problems. The basic issue in dynamics problems is solving the fundamental dynamic equation, ∑F = ma. Perhaps the most common form of problem in dynamics requires that the acceleration of a given mass be determined when the mass is subjected to known forces. Sometimes more than one mass is involved; occasionally the mass is the unknown quantity to be determined
matlab (for the beginners)
The tutorials are independent of the rest of the document. The primarily objective is to help you learn quickly the first steps. The emphasis here is “learning by doing”. Therefore, the best way to learn is by trying it yourself. Working through the examples will give you a feel for the way that MATLAB operates. In this introduction we will describe how MATLAB handles simple numerical expressions and mathematical formulas. The name MATLAB stands for MATrix LABoratory. MATLAB was written originally to provide easy access to matrix software developed by the LINPACK (linear system package) and EISPACK (Eigen system package) projects. MATLAB [1] is a high-performance language for technical computing. It integrates computation, visualization, and programming environment. Furthermore, MATLAB is a modern programming language environment: it has sophisticated data structures, contains built-in editing and debugging tools, and supports object-oriented programming. These factors make MATLAB an excellent tool for teaching and research. MATLAB has many advantages compared to conventional computer languages (e.g., C, FORTRAN) for solving technical problems. MATLAB is an interactive system whose basic data element is an array that does not require dimensioning. The software package has been commercially available since 1984 and is now considered as a standard tool at most universities and industries worldwide.
