Multiobjective Optimization in Imrt Treatment Planning
ISBN: 9783838372631 / Angielski / Miękka / 196 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The aim of intensity modulated radiation therapy (IMRT) is to kill tumor cells while at the same time protecting the surrounding tissue and organs from the damaging effect of radiation. Given the number of beams and beam directions, beam intensity optimization needs to determine beam intensity profiles that yield the best dose distribution under consideration of clinical and physical constraints. In this book, we first review existing mathematical models and computation methods for the beam intensity optimization problem. Then we formulate the beam intensity optimization problem ...

Classical q-Numbers: A Study of the Case q = -1
ISBN: 9783838337586 / Angielski / Miękka / 88 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Several of the classical sequences in enumerative combinatorics have q-generalizations arising as generating functions for statistics defined on finite discrete structures. When q = 1, these generating functions reduce to the original sequences. When q = -1, on the other hand, one gets the difference in cardinalities between those members of a set having an even value for some statistic (on the set) with those members having an odd value. The current text provides a systematic study of the case q = -1, giving both algebraic and combinatorial treatments. For the latter, ...

Multiobjective Programming Under Generalized Invexity
ISBN: 9783838373355 / Angielski / Miękka / 152 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. In the invex problems, it is required to consider a same function for the objective and constraint functions. Because of this restriction, various difficulties are encountered in applications related to optimality and duality properties. To improve this situation, in this work, the invexity with respect to different functions ( i) is proposed to study optimality conditions and duality for nonlinear and multiobjective programming problems with or without differentiability. Under this generalized invexity or its extensions assumptions, new Kuhn-Tucker (Fritz-John) type necessary and sufficient...

ISBN: 9783843362184 / Angielski / Miękka / 112 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The design of efficient Micro heat Pipes requires efficient heat transport capability. In this work steady-liquid flow and heat transfer in a micro heat pipe with triangular, rectangular and advanced capillary shaped grooves have been closely examined, to study the maximum heat transport capability of cooling devices such as micro heat pipes. A lubrication-type model of liquid flow and heat transfer under negligible gravity and small capillary number is considered. The adiabatic region plays an important role in determining the flow rate. The flow rate could be controlled by changing the...

Amenability of Beurling Algebra
ISBN: 9783843365482 / Angielski / Miękka / 108 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. In this monograph, some new techniques are developed to define derivation on a Beurling algebra. Moreover, the amenability, weak amenability of a Beurling algebra and amenability of its second dual are discussed. Also, it is shown that if G is non-discrete, then the Banach algebra M(G, w) is not weakly amenable. Finally, the conjecture of H.G.Dales and A.T.M.Lau about 2-weakly amenability of a Beurling algebra is proved with an additional condition which is weaker than almost invariance

Laplacian Spectrum and Graph Structure
ISBN: 9783843386142 / Angielski / Miękka / 96 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The Laplacian matrix of a graph and its eigenvalues can be used in several areas of mathematical research and have a physical interpretation in various physical and chemical theories. The related matrix, the adjacency matrix of a graph and its eigenvalues were much more investigated in the past than the Laplacian matrix. However in my opinion the Laplacian spectrum is much more natural and more important than the adjacency matrix spectrum. We have used the standard terminology of graph theory, as it is introduced in most text books on the theory of graphs. We have studied the graph structure...

Block Methods for Special Second Order Ordinary Differential Equations
ISBN: 9783844384130 / Angielski / Miękka / 196 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Various types of methods have been developed for solving the special second order ODEs which is not explicitly dependent on the first derivative of the solution. The solution to the equation can be obtained by reducing it to an equivalent first order system of twice the dimension and solved using a standard numerical methods. However it is often advantageous to solve them directly. This book focused on the derivation of the block methods for solving the special second order ODEs directly. The early section of the book is devoted to the derivation of the methods using linear operator. Then...

Factorization of Quasiseparable Matrices
ISBN: 9783838306544 / Angielski / Miękka / 72 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. The class of quasiseparable matrices includes several other well-known matrices, such as band matrices, diagonal plus semiseparable matrices, tridiagonal matrices, and unitary Hessenberg matrices; and arises naturally in classical control theory. As with any matrix operator, computational benefits can be obtained from factoring, especially by utilizing unitary factors. This book provides some detail concerning a current (largely unitary) approach to factoring quasiseparable matrices described by Y. Eidelman and I. Gohberg (2002), derived in part from a previous description by P. M. Dewilde...

Mathematical modelling of avascular tumour growth
ISBN: 9783843354899 / Angielski / Miękka / 72 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. While major advances have been made in the area of cancer research over the last few decades, certain aspects of the avascular tumour growth processes remain poorly understood. The mathematical model discussed in this monograph therefore provides a more biologically realistic description of avascular tumour growth by taking into account stochastic cellular and extracellular tumour growth processes. The discussion is presented in two distinct parts- the first comprises the construction of a model for avascular tumour growth with random variation, while the second consists of refining...

The Scale of a Quasi-Uniform Space
ISBN: 9783843385626 / Angielski / Miękka / 92 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. We continue our investigations of the scale of a quasi-uniform space, which we had started in an earlier article. We distinguish between the left-sided scale and the two-sided scale of a quasi-uniform space. While the behavior of the two-sided scale of a quasi-uniform space X shows similarities with the usual hyperspace of X equipped with its Hausdorff quasi-uniformity, the left-handed scale generalizes the quasi-uniform multifunction space of X into itself.For instance the two-sided scale of any totally bounded quasi-uniform space X is totally bounded, while total boundedness of the ...

ISBN: 9783843386647 / Angielski / Miękka / 112 str. Termin realizacji zamówienia: ok. 5-8 dni roboczych. Nonpolynomial Spline Methods (NPSMs) are presented for solving single and system of boundary value problems (BVPs) of orders two, four, six and an 2mth order BVPs respectively. Also, the numerical solution of singular second order BVPs is considered. Optimal order approximations to the solutions of these boundary value problems are obtained. The matrix properties of these BVPs, arising from the discretization of systems of BVPs by NPSMs, are discussed. Sufficient conditions for the optimal convergence for NPSMs are obtained. Also, NPSMs generalize other recent finite difference methods and...

In this paper a regularized spectral estimation formula and a regularized iterative algorithm for band-limited extrapolation are presented. The ill-posedness of the problem is taken into account. First a Fredholm equation is regularized. Then it is transformed to a differential equation in the case where the time interval is {bf R}. A fast algorithm to solve the differential equation by the finite differences is given and a regularized spectral estimation formula is obtained. Then a regularized iterative extrapolation algorithm is introduced and compared with the Papoulis and Gerchberg...
