Abstract: For commutative Banach algebras B and I and a continuous representation π: B → M(I), where M(I) are those bounded linear operators T: I → I that satisfy T(ij) = iT(j) for all i,j in I, the direct sum B I can be made into a commutative Banach algebra which contains B and I as respectively a closed subalgebra and a closed ideal. This algebra is called the semidirect product of B and I. Some topological aspects of the character space of a semidirect product are described. Furthermore, decompositions of commutative Banach algebras into the direct sum of a subalgebra and a principal ideal are investigated.

Electronic subscription at Library TUDelft  

Abstract: In general, the orientation interpolation of industrial robots has been done based on Euler angle system which can result in singular point (so-called Gimbal Lock). However, quaternion interpolation has the advantage of natural (specifically smooth) orientation interpolation without Gimbal Lock.

This work presents the application of quaternion interpolation, specifically Spherical Linear IntERPolation (SLERP), to the orientation control of the 6-axis articulated robot (RS2) using LabVIEW and RecurDyn.

For the comparison of SLERP with linear Euler interpolation in the view of smooth movement (profile) of joint angles (torques), the two methods are dynamically simulated on RS2 by using both LabVIEW and RecurDyn.

Finally, our original work, specifically the implementation of SLERP and linear Euler interpolation on the actual robot, i.e. RS2, is done using LabVIEW motion control tool kit. The SLERP orientation control is shown to be effective in terms of smooth joint motion and torque when compared to a conventional (linear) Euler interpolation.

Abstract: It is shown that widely used implicit schemes, in particular the classical Newmark family of algorithms and its variants, generally fail to conserve total angular momentum for nonlinear Hamiltonian systems including classical rigid body dynamics, nonlinear elastodynamics, nonlinear rods and nonlinear shells.
For linear Hamiltonian systems, it is well known that only the Crank-Nicholson scheme exactly preserves the total energy of the system.
This conservation property is typically lost in the nonlinear regime. A general class of implicit time-stepping algorithms is presented which preserves exactly the conservation laws present in a general Hamiltonian system with symmetry, in particular the total angular momentum and the total energy.
Remarkably, the actual implementation of this class of algorithms can be effectively accomplished by means of a simple two-step solution scheme which results in essentially no added computational cost relative to standard implicit methods.
A complete analysis of these algorithms and a related class of schemes referred to as symplectic integrators is given.
The good performance of the proposed methodology is demonstrated by means of three numerical examples which constitute representative model problems of nonlinear elastodynamics, nonlinear rods and nonlinear shells.

Abstract: The present discourse develops an enlarged exploration of the matrix formulation of finite rotations in space initiated in [1]. It is shown how a consistent but subtle matrix calculus inevitably leads to a number of elegant expressions for the transformation or rotation matrix T appertaining to a rotation about an arbitrary axis. Also analysed is the case of multiple rotations about fixed or follower axes. Particular attention is paid to an explicit derivation of a single compound rotation vector equivalent to two consecutive arbitrary rotations. This theme is discussed in some detail for a number of cases. Semitangential rotations—for which commutativity holds—first proposed in [2, 3] are also considered. Furthermore, an elementary geometrical analysis of large rotations is also given. Finally, we deduce in an appendix, using a judicious reformulation of quarternions, the compound pseudovector representing the combined effect of n rotations. In the author's opinion the present approach appears preferable to a pure vectorial scheme—and even more so to an indicial formulation— and is computationally more convenient.

Abstract: We show how to represent perspective projections in 3-dimensions using rotations in 4-dimensions. This representation permits us to replace classical singular 4x4 matrices for perspective projection with nonsingular 4x4 orthogonal matrices. This approach also allows us to compute perspective projections by sandwiching vectors between two copies of a unit quaternion. In addition to deriving explicit formulas for these 4x4 rotation matrices for perspective projection, we also explain the geometric intuition underlying the observation that perspective projections in 3-dimensions can be represented by rotations in 4-dimensions. We show too that every rotation in 4-dimensions models either a rotation, a reflection, a perspective projection, or one of their composites in 3-dimensions.

Abstract: Schwinger has pointed out that the Yang-Mills vector boson implied by associating a generalized gauge transformation with a conservation law (of baryonic charge, for instance) does not necessarily have zero mass, if a certain criterion on the vacuum fluctuations of the generalized current is satisfied. We show that the theory of plasma oscillations is a simple nonrelativistic example exhibiting all of the features of Schwinger's idea. It is also shown that Schwinger's criterion that the vector field m≠0 implies that the matter spectrum before including the Yang-Mills interaction contains m=0, but that the example of superconductivity illustrates that the physical spectrum need not. Some comments on the relationship between these ideas and the zero-mass difficulty in theories with broken symmetries are given.

The notion, introduced 50 years ago, that electrons could be affected by electromagnetic potentials without coming in contact with actual force fields was received with a skepticism that has spawned a flourishing of experimental tests and expansions of the original idea.

Editorial Reviews
From the Back Cover

The idea of modeling the behavior of phenomena at multiple scales has become a useful tool in both pure and applied mathematics.
Fractal-based techniques lie at the heart of this area, as fractals are inherently multiscale objects; they very often describe nonlinear phenomena better than traditional mathematical models. In many cases they have been used for solving inverse problems arising in models described by systems of differential equations and dynamical systems.   
"Fractal-Based Methods in Analysis" draws together, for the first time in book form, methods and results from almost twenty years of research in this topic, including new viewpoints and results in many of the chapters.  
For each topic the theoretical framework is carefully explained using examples and applications.   
The second chapter on basic iterated function systems theory is designed to be used as the basis for a course and includes many exercises.  This chapter, along with the three background appendices on topological and metric spaces, measure theory, and basic results from set-valued analysis, make the book suitable for self-study or as a source book for a graduate course.
The other chapters illustrate many extensions and applications of fractal-based methods to different areas.
This book is intended for graduate students and researchers in applied mathematics, engineering and social sciences.

Summary: Next week, physicists working with the world's biggest atom smasher—the Large Hadron Collider (LHC) at the European particle physics laboratory, CERN—will report the latest results of searches for the Higgs, the key to physicists' explanation of how all particles get their mass. Nobody expects a definitive claim of discovery, but given the amount of data the LHC has produced in 2 years of running, some physicists say that—if it's there—the Higgs should begin to emerge from "background" particle collisions like a sapling rising above the grass.

Abstract: Quaternion multiplication can be applied to rotate vectors in 3-dimensions. Therefore in Computer Graphics, quaternions are sometimes used in place of matrices to represent rotations in 3-dimensions. Yet while the formal algebra of quaternions is well-known in the Graphics community, the derivations of the formulas for this algebra and the geometric principles underlying this algebra are not well understood.
The goals of this paper are:

i.To provide a fresh geometric interpretation of quaternions, appropriate for contemporary Computer Graphics;

ii.To derive the formula for quaternion multiplication from first principles;

iii.To present better ways to visualize quaternions,and the effect of quaternion multiplication on points and vectors in 3-dimensions based on insights from the algebra and geometry of multiplication in the complex plane;

iv.To develop simple, intuitive proofs of the sandwiching formulas for rotation and reflection;

v.To show how to apply sandwiching to compute perspective projections.

In Part I of this paper, we investigate the algebra of quaternion multiplication and focus in particular on topics i and ii.
In Part IIwe apply our insights from Part I to analyze the geometry of quaternion multiplication with special emphasis on topics iii, iv and v.

Abstract: 600-cell{3, 3, 5} and 120-cell {5, 3, 3} four-dimensional dual polytopesrelevant to quasicrystallography have been studied with thequaternionic representation of the Coxeter group W(H4). The maximal subgroups W(SU(5)):Z2and W(H3) × Z2of W(H4) play important roles in the analysis of cell structures of the dual polytopes. In particular, the Weyl–Coxeter group W(SU(4)) is used to determine the tetrahedral cells of the polytope {3, 3, 5}, and the Coxeter group W(H3)is used for the dodecahedral cells of {5, 3, 3}. Using the Liealgebraic techniques in terms of quaternions, we explicitly constructcell structures forming the vertices of the 4D polytopes.
