Digital Portfolio Theory
Authors: C. Kenneth Jones
Venue: Computational Economics (2001)

The Modern Portfolio Theory of Markowitz maximized portfolio expected return subject to holding total portfolio variance below a selected level. Digital Portfolio Theory is an extension of Modern Portfolio Theory, with the added dimension of memory. Digital Portfolio Theory decomposes the portfolio variance into independent components using the signal processing decomposition of variance. The risk or variance of each security's return process is represented by multiple periodic components. These periodic variance components are further decomposed into systematic and unsystematic parts relative to a reference index. The Digital Portfolio Theory model maximizes portfolio expected return subject to a set of linear constraints that control systematic, unsystematic, calendar and non-calendar variance. The paper formulates a single period, digital signal processing, portfolio selection model using cross-covariance constraints to describe covariance and autocorrelation characteristics. Expected calendar effects can be optimally arbitraged by controlling the memory or autocorrelation characteristics of the efficient portfolios. The Digital Portfolio Theory optimization model is compared to the Modern Portfolio Theory model and is used to find efficient portfolios with zero calendar risk for selected periods.
A cooperative asynchronous write mechanism for NAS
Authors: Lu Jun, Lu Xianliang, Han Hong, Wei Qingsong
Venue: ACM SIGOPS Operating Systems Review (2002)

Network Attached Storage (NAS) is the high performance storage appliance that provides shared data to clients and other servers in a Local Area Network (LAN). The existing NAS products provide file services by themselves. They can not cooperate with each other to improve performance. This paper presents an automatically cooperative asynchronous write mechanism for NAS: ACAWM. ACAWM is a set of pure software mechanisms which provide both the reliability of synchronous write operations and the performance of asynchronous write operations. ACAWM contains two parts: automatically cooperative mechanism and asynchronous write mechanism. The automatically cooperative mechanism of ACAWM can make all NAS in a LAN to cooperate with each other without artificial configuration. Basing on the automatically cooperative mechanism, asynchronous write mechanism of ACAWM can allow a NAS to use the free RAM of the cooperative NAS to realize asynchronous write in the file system of NAS. The data of asynchronous write in ACAWM are saved on both of the two cooperative NAS before being written to disk, thus ACAWM can ensure the security of data. The design of ACAWM fully considers the usability of NAS and has no special requirement for the system software of clients. The experiments in this paper prove that ACAWM can greatly improve the performance of NAS.

Hartley Transform Representations of Symmetric Toeplitz Matrix Inverses with Application to Fast Matrix-Vector Multiplication
Authors: Georg Heinig, Karla Rost
Venue: SIAM Journal on Matrix Analysis and Applications (2000)

Representations for inverses of real symmetric Toeplitz matrices involving discrete Hartley transformations are presented which can be used for fast matrix-vector multiplication. In this way, multiplication of a column vector by an inverse real symmetric Toeplitz matrix can be carried out with the help of six Hartley transformations plus two for preprocessing. Besides complexity, stability issues will also be discussed. In particular, it is shown that, for positive definite Toeplitz matrices, the relative error of the computed vector can be estimated by a multiple of the condition number of the matrix.
Transmission Systems, 1st edition
Authors: J. E. Flood
Venue:  (1991)

:The past 15 years have seen very rapid progress in the technology of telecommunications and the development of services which have totally eclipsed the evolution of the previous 100 years. Transmission-system development has played a key role in this progress, with the migration from analogue carrier systems operating over twisted-pair, coaxial and radio bearers to digital systems which are now concentrated on optical fibre. These changes have themselves been fuelled by the dramatic progress made in semiconductor technology, which opened the door to an unprecedented revolution in electronic equipment and information technology. The direct result has been a very rapid fall in the cost of transmitting information over long distances.Numerous new service opportunities have thus arisen with the realization of low-cost transmission and the availability of highly-integrated terminal equipment. Now, there is no facet of life which is not influenced by telecommunications. Transmission networks form an essential part of the infrastructure of all modern industrialized nations, and a key contributor to their economic success and social stability.This volume addresses telecommunications transmission over the modern period, using both analogue and digital technology.The book is organized to form a natural progression from the fundamental need for telecommunications, the transmission media available, systems options and design, performance specification and requirements, to the network planning process, and finally, future trends.

Attributed grammars for query language translations
Authors: C. M. R. Kintala
Venue: Proceedings of the 2nd ACM SIGACT-SIGMOD symposium on Principles of database systems (1983)

Systems which translate queries written using a high-level conceptual model of a database into sequences of commands based on another model of the database are studied here. We take the view that these translators are similar to, albeit simpler than, the compilers for programming languages. Motivated by the recent interest in describing all the aspects of a compiler by an attributed grammar, we specify the formal syntax and semantics of two working database translators using attributed grammars. All the precise details about the parsing, the code optimization and the rules for preserving the query semantics are captured by those grammars. It is hoped that this approach brings the understanding of query languages closer to that of programming languages, and opens the possibility of applying the emerging technology of semantics-directed compiler construction to build query language translator-generators and to prove those translators correct.

On some difficult linear programs coming from set partitioning
Authors: Francisco Barahona, Ranga Anbil
Venue: Discrete Applied Mathematics (2002)

We deal with the linear programming relaxation of set partitioning problems arising in airline crew scheduling. Some of these linear programs have been extremely difficult to solve with the traditional algorithms. We have used an extension of the subgradient algorithm, the volume algorithm, to produce primal solutions that might violate the constraints by at most 2%, and that are within 1% of the lower bound. This method is fast, requires minimal storage, and can be parallelized in a straightforward way.
The distributions of the entries of Young tableaux
Authors: Brendan D. McKay, Jennifer Morse, Herbert S. Wilf
Venue: Journal of Combinatorial Theory Series A (2002)

Let T be a standard Young tableau of shape λ ⊢ k. We show that the probability that a randomly chosen Young tableau of n cells contains T as a subtableau is, in the limit n → ∞, equal to fλ/k!, where fλ is the number of all tableaux of shape λ. In other words, the probability that a large tableau contains T is equal to the number of tableaux whose shape is that of T, divided by k!. We give several applications, to the probabilities that a set of prescribed entries will appear in a set of prescribed cells of a tableau, and to the probabilities that subtableaux of given shapes will occur. Our argument rests on a notion of quasirandomness of families of permutations, and we give sufficient conditions for this to hold.
A Java-based framework to support computer-assisted creation of structured XML documents
Authors: Andrea Trentini
Venue: ACM SIGAPP Applied Computing Review (2002)

In the management of document-based information, the structure of the document itself is very important. In the XML world you can use a DTD (Document Type Definition) or XMLSchema to define that structure. But not everything can be described (and forced) through a DTD while XMLSchema is not yet widely supported. For our MENTOR project - a document-based university management system - we needed a tool to support the creation and storage of official-meeting transcripts. These documents are strongly structured, so strongly that in this case a simple DTD was not enough. We decided to build a custom tool to fulfill our need. In this article we show the different solutions we had to study to let users create XML documents with some considerations about the formalization level of each solution. Then we present and motivate our choice.

A Frank&ndash;Wolfe Type Theorem for Convex Polynomial Programs
Authors: Evgeny G. Belousov, Diethard Klatte
Venue: Computational Optimization and Applications (2002)

In 1956, Frank and Wolfe extended the fundamental existence theorem of linear programming by proving that an arbitrary quadratic function f attains its minimum over a nonempty convex polyhedral set X provided f is bounded from below over X. We show that a similar statement holds if f is a convex polynomial and X is the solution set of a system of convex polynomial inequalities. In fact, this result was published by the first author already in a 1977 book, but seems to have been unnoticed until now. Further, we discuss the behavior of convex polynomial sets under linear transformations and derive some consequences of the Frank&ndash;Wolfe type theorem for perturbed problems.

A Method for Computing Nearly Singular Integrals
Authors: J. Thomas Beale, Ming-Chih Lai
Venue: SIAM Journal on Numerical Analysis (2000)

We develop a method for computing a nearly singular integral, such as a double layer potential due to sources on a curve in the plane, evaluated at a point near the curve. The approach is to regularize the singularity and obtain a preliminary value from a standard quadrature rule. Then we add corrections for the errors due to smoothing and discretization, which are found by asymptotic analysis. We prove an error estimate for the corrected value, uniform with respect to the point of evaluation. One application is a simple method for solving the Dirichlet problem for Laplace's equation on a grid covering an irregular region in the plane, similar to an earlier method of A. Mayo [SIAM J. Sci. Statist. Comput., 6 (1985), pp. 144--157]. This approach could also be used to compute the pressure gradient due to a force on a moving boundary in an incompressible fluid. Computational examples are given for the double layer potential and for the Dirichlet problem.

Strategy-based decision making of a soccer robot system using a real-time self-organizing fuzzy decision tree
Authors: Han-Pang Huang, Chao-Chiun Liang
Venue: Fuzzy Sets and Systems (2002)

In a soccer robot game, the environment is highly competitive and dynamic. In order to work in the dynamically changing environment, the decision-making system of a soccer robot system should have the features of flexibility and on-line adaptation. This paper proposed a strategy-based decision-making system for a soccer robot system. The decision system is based on the proposed self-organizing fuzzy decision tree (SOFDT). Due to event-driven strategies, the proposed decision-making system has the advantage of flexibility. The proposed SOFDT possesses simple, apparent, and fast generation/reasoning processes. The resultant system is a self-organizing strategy-based decision-making system. According to decision results, SOFDT can on-line modify its parameters and structure for achieving better adaptability and improvement. The performance of the proposed systems was verified by applying them to the simulation and experiment of 3-to-3 robot soccer games. The results are satisfactory.

Adaptive algorithm for vector field interpolation based on octree structure
Authors: Pavel Tisnovsky, Adam Herout
Venue: Proceedings of the 18th spring conference on Computer graphics (2002)

Computer graphics helps mathematicians and physicians visualize calculations and processed data. Visualization algorithms operating on vector field [9], [13], such as particle-tracing, require continuous (defined for every (x, y, z) position within the space), not necessarily very accurate, but fast and smooth interpolation of the field values. We offer a way of storing vector field in an octree structure, which offers some degree of compression and adaptive density of sampling of the vector field.The presented algorithm solves adaptive interpolation of vectors stored in octree. Our experiments show that this algorithm gives better results than interpolation in a regular grid without requiring more computation time.
