  • Here we present a collection of examples of general systems of linear differential equations and some applications in Physics and the Technical Sciences. The reader is also referred to Calculus 4b as well as to Calculus 4c-2. It should no longer be necessary rigourously to use the ADIC-model, described in Calculus 1c and Calculus 2c, because we now assume that the reader can do this himself. Even if I have tried to be careful about this text, it is impossible to avoid errors, in particular in the first edition. It is my hope that the reader will show some understanding of my situation....

  • Modern Spectroscopy has been written to fulfil a need for an up-to-date text on spectroscopy. It is aimed primarily at a typical undergraduate audience in chemistry, chemical physics, or physics in the United Kingdom and at undergraduate and graduate student audiences elsewhere. Spectroscopy covers a very wide area which has been widened further since the mid- 1960s by the development of lasers and such techniques as photoelectron spectroscopy and other closely related spectroscopies.

  • The bremsstrahlung beam with energy end point of 65M eV created when the e− beam with energy of 65M eV irradiated to thin wolfram target was used to irradiate to TiO2 sample in order to make the 46 Ti (γ, pn)44m,g Sc reaction. The gamma spectrum of Sc44m,g was analyzed by the gammavision spectrometry with HPGe detector at linear accelerator laboratory in POSTECH, Korea.

  • The advent of cancer therapy with the use of varous particle beams requires full understanding of radiation interactions with tumours and other materials for its optimal perfomance. Relevant knowledge in this respect comes from physics, chemistry, biology, medicine, and related technologies. A basic item of required Knowledge are the physical data that characterize the earliest phase of radiation interactions on the molecular level, which sets a stage for subsequent chemical and biological effects including the control of cancer.

  • This paper presents a new design method for all-optical NAND and AND logic gates based on 3x3 general interference multimode interference (GI MMI) coupler. The whole device is realized on the silicon on insulator (SOI) platform. The transfer matrix method (TMM) and three dimensional beam propagation method (3D-BPM) are used to optimally design these devices. Key words: Optical logic gate, multimode interference (MMI) coupler, silicon on insulator (SOI), beam propagation method (BPM)

  • A bridge is a structure built to span physical obstacles such as a body of water, valley, or road, for the purpose of providing passage over the obstacle. Designs of bridges vary depending on the function of the bridge, the nature of the terrain where the bridge is constructed, the material used to make it and the funds available to build it.

  • Ion implantation represents a particularly useful means by which to modify the surface properties of a variety of materials. This prosaic statement, however, does not convey the depth of basic understanding which has been developed to fully utilize the advantages of ion implantation. The interaction of a host lattice with the energetic beams produces metastable states and structures which cannot be achieved by other means. However, ion implantation also requires an understanding of the fundamental physics and chemistry that dictate the interaction of the ion beam and the target.

  • Flow cytometry is a technology that simultaneously measures and analyses multiple physical characteristics of single particles, usually cells, as they flow in a fluid stream through a beam of light. The properties measured include a particle’s relative size (represented by forward angle light scatter), relative granularity or internal complexity (represented by right-angle scatter), and relative fluorescence intensity.

  • Metal nanoparticles are certain to be the building blocks of the next generation of electronic, optoelectronic and chemical sensing devices. The physical limits imposed by top-down methods such as photo- and electron- beam lithography dictate that the synthesis and assembly of functional nanoscale materials will become the province of chemists.

  • This book evolved from the first term of a two-term course on the physics of charged particle acceleration that I taught at the University of New Mexico and at Los Alamos National Laboratory. The first term covered conventional accelerators in the single particle limit. The second term covered collective effects in charged particle beams, including high current transport and instabilities. The material was selected to make the course accessible to graduate students in physics and electrical engineering with no previous background in accelerator theory.

  • Three-dimensional (3D) laser micro-fabrication has become a fast growing field of science and technology. The very first investigations of the laser modifications and structuring of materials immediately followed the invention of the laser in 1960. Starting from the observed photomodifications of laser rod materials and ripple formation on the irradiated surfaces as unwanted consequences of a high laser fluence, the potential of material structuring was tapped.
