Optimization of the Production Planning and Trade of Lily Flowers at Jan de Wit Company
Authors: José Vicente Caixeta-Filho, Jan Maarten van Swaay-Neto, Antonio de Pádua Wagemaker
Venue: Interfaces (2002)

Jan de Wit Company implemented a decision-support system based on linear programming as a production-planning and trade tool for the management of its lily flower business. The LP maximizes the farm's total contribution margin, subject to such constraints as market-defined sales limits, market requirements, characteristics of the production cycle duration, technical requirements, bulb inventory, and greenhouse limitations. The main decision variable to be calculated is the number of flower beds in a specific greenhouse, from a specific bulb batch, of a specific variety, for a specific purpose, taking into consideration planting and expected harvesting weeks. Between 1999 and 2000, company revenue grew 26 percent, sales increased 14.8 percent for pots of lilies and 29.3 percent for bunches of lilies, costs fell from 87.9 to 84.7 percent of sales, income from operations increased 60 percent, return on owner's equity went from 15.1 to 22.5 percent, and best quality cut lilies jumped from 11 to 61 percent of the quantities sold. The system also suggested changes in the product mix.

Why informal information technology management models do not work
Authors: James Lackey, Steve Brown
Venue: Proceedings of the 30th annual ACM SIGUCCS conference on User services (2002)

Thirty years ago, very few universities had information technology departments. The university personnel who worked with computer technology usually had backgrounds in mathematics or engineering. Technology management was an alien concept. This worked fine for that era because there was very little technology to manage and therefore, very few Information Technology personnel to manage. As the discipline matured, the need for management increased. Since management was not the first love of most of the mathematicians and engineers running the Information Technology departments, informal, poorly thought out, management structures arose. Some of these unworkable models still exist within university Information Technology departments today.

Approach for software development of parallel real-time VE systems on heterogenous clusters
Authors: C. Winkelholz, T. Alexander
Venue: Proceedings of the Fourth Eurographics Workshop on Parallel Graphics and Visualization (2002)

This paper presents our approach for the development of software for parallel real-time virtual environment systems (VE) running on heterogenous clusters of computers. This approach is based on a framework we have developed to facilitate the set-up of immersive virtual environment systems using single components coupled by an isolated local network. The framework provides parallel rendering of multiple projection screens and parallel execution of application and interaction tasks on components spread across a cluster. Main concept of the approach discussed in this paper is to use the virtual reality modeling language (VRML) as an interface definition language (IDL) for the parallel and distributed virtual environment system. An IDL-compiler generates skeleton-code for the implementations of the script nodes specified in a VRML-file. Components created this way can be reused in any VE by declaring the same interfaces. Instances of the implemented interfaces can reside in any application. By this approach commercial-of-the-shelf software can easily be integrated into a VE application. In this connection we discuss the underlying framework and software development process. Furthermore, the implementation of a VE system for a geographic information system (GIS) based on this approach is shown. It is emphasized that the components are used in various different applications.
A Uniform Internet-Communicative Agent
Venue: Electronic Commerce Research (2001)

A universal HTML-based communication is described and experimentally implemented in the EMA employment agent. EMA can contact any HTML-based program or database on the Internet on the basis of a single observation of a user filling input forms. After one observation, EMA is capable of gathering information on its own by modifying familiar input forms. While EMA in theory communicates with any other program on the Internet, its performance strongly relies on domain knowledge allowing reasonable guessing about the meaning of major input fields. Another human-type communication in the system is by speech using a Microsoft agent in English and our speech system in Slovenian. The system is in use for seven years. The number of accesses equals all residents in our country in one year.
Computational Design of Optimal Output Feedback Controllers
Authors: T. Rautert, E. W. Sachs
Venue: SIAM Journal on Optimization (1997)

We consider the problem of designing feedback control laws when a complete set of state variables is not available. For linear autonomous systems with quadratic performance criterion, the design problem consists of choosing an appropriate matrix of feedback gains according to a certain objective function. In the literature, the performance of quasi-Newton methods has been reported to be substandard. We try to explain some of these observations and to propose structured quasi-Newton updates. These methods, which take into account the special structure of the problem, show considerable improvement in the convergence. Using test examples from optimal output feedback design, we also can verify these results numerically.
Relational learning and boosting
Authors: Ross Quinlan
Venue: Relational Data Mining (2001)

Boosting, a methodology for constructing and combining multiple classifiers, has been found to lead to substantial improvements in predictive accuracy. Although boosting was formulated in a propositional learning context, the same ideas can be applied to first-order learning (also known as inductive logic programming). Boosting is used here with a system that learns relational definitions of functions. Results show that the occasional negative impact of boosting all resemble the corresponding observations for propositional learning.
Hardness of Approximate Hypergraph Coloring
Authors: Venkatesan Guruswami, Johan Hastad, Madhu Sudan
Venue: SIAM Journal on Computing (2002)

We introduce the notion of covering complexity of a verifier for probabilistically checkable proofs (PCPs). Such a verifier is given an input, a claimed theorem, and an oracle, representing a purported proof of the theorem. The verifier is also given a random string and decides whether to accept the proof or not, based on the given random string. We define the covering complexity of such a verifier, on a given input, to be the minimum number of proofs needed to "satisfy" the verifier on every random string; i.e., on every random string, at least one of the given proofs must be accepted by the verifier. The covering complexity of PCP verifiers offers a promising route to getting stronger inapproximability results for some minimization problems and, in particular, (hyper)graph coloring problems. We present a PCP verifier for NP statements that queries only four bits and yet has a covering complexity of one for true statements and a superconstant covering complexity for statements not in the language. Moreover, the acceptance predicate of this verifier is a simple not-all-equal check on the four bits it reads. This enables us to prove that, for any constant c, it is NP-hard to color a 2-colorable 4-uniform hypergraph using just c colors and also yields a superconstant inapproximability result under a stronger hardness assumption.

Proactive Power-Aware Cache Management for Mobile Computing Systems
Authors: Guohong Cao
Venue: IEEE Transactions on Computers (2002)

Recent work has shown that invalidation report (IR)-based cache management is an attractive approach for mobile environments. However, the IR-based cache invalidation solution has some limitations, such as long query delay, low bandwidth utilization, and it is not suitable for applications where data change frequently. In this paper, we propose a proactive cache management scheme to address these issues. Instead of passively waiting, the clients intelligently prefetch the data that are most likely used in the future. Based on a novel prefetch-access ratio concept, the proposed scheme can dynamically optimize performance or power based on the available resources and the performance requirements. To deal with frequently updated data, different techniques (indexing and caching) are applied to handle different components of the data based on their update frequency. Detailed simulation experiments are carried out to evaluate the proposed methodology. Compared to previous schemes, our solution not only improves the cache hit ratio, the throughput, and the bandwidth utilization, but also reduces the query delay and the power consumption.

Adaptive Eigenvalue Computations Using Newton's Method on the Grassmann Manifold
Authors: Eva Lundström, Lars Eldén
Venue: SIAM Journal on Matrix Analysis and Applications (2001)

We consider the problem of updating an invariant subspace of a large and structured Hermitian matrix when the matrix is modified slightly. The problem can be formulated as that of computing stationary values of a certain function with orthogonality constraints. The constraint is formulated as the requirement that the solution must be on the Grassmann manifold, and Newton's method on the manifold is used. In each Newton iteration a Sylvester equation is to be solved. We discuss the properties of the Sylvester equation and conclude that for large problems preconditioned iterative methods can be used. Preconditioning techniques are discussed. Numerical examples from signal subspace computations are given in which the matrix is Toeplitz and we compute a partial singular value decomposition corresponding to the largest singular values. Further we solve numerically the problem of computing the smallest eigenvalues and corresponding eigenvectors of a large sparse matrix that has been slightly modified.

Practical Data Analysis,Volume III, 2nd edition
Authors: Peter G. Bryant, Marlene A. Smith
Venue:  (1998)

:Practical Data Analysis: Case Studies in Business Statistics is a collection of 75 class tested case studies for use in introductory business statistics and general statistics. All cases are drawn from real situations in a broad range of business,economic,and social science settings and include small and large data sets for analysis by students. The philosophy behind the package is to let the cases and data drive or supplement the course. Doing so provides three important opportunities for students and instructors: useful computing experience,hands-on activity,which is more motivating than the traditional course format,and a sense of realism about the use of statistics.
An array-oriented (APL) wish list: ideas I think may be useful
Authors: Jim Lucas
Venue: Proceedings of the 2001 conference on APL: an arrays odyssey (2001)

The fundamental, data structure in APL is the array. Arrays are, in most APL dialects, the only data structure, from scalars as arrays with no dimensions to the complex structures of nested arrays. But there are other ways in which array concepts could be applied, yet so far they have not. These are the top items on my "Array-Oriented Wish List".Less fundamental---but far easier to implement---should be certain operators and functions I propose, which I think would enhance the power of existing array operations. Some of these already exist in one or more dialects of APL, and I think all would benefit if they were universally adopted.In this suite of proposals, some are general, others more specific, and some could interact with each other in positive synergy, but none of them requires any of the others to be useful. In some cases, I suggest potential variants, each reasonable in its own right.The purpose of this paper is to present the concepts. In most cases, I don't attempt to go into details of implementation. That would require a much more extensive treatment of each concept. I hope that others---especially implementers---might take up the challenge.
Building multi-device, component-based, thin-client groupware: issues and experiences
Authors: John Grundy, Xing Wang, John Hosking
Venue: Proceedings of the Third Australasian conference on User interfaces - Volume 7 (2002)

The use of groupware, or collaborative work-supporting technologies, has become wide-spread, but many existing groupware systems are too difficult to integrate with domain-specific software applications, only work for specific user interface hardware, or provide inappropriate, thick-client architectural solutions. We describe a set of server-side software components we have developed providing a variety of thin-client groupware solutions (chat, email, annotation, to-do lists, notification etc). These components provide HTML and WML-based thin-client user interfaces and can be readily "plugged into" the server-side architectures of domain-specific applications. We focus on the key issues of designing and realising the user interfaces for such groupware solutions and report on our experiences to date.
Support for subtyping and code re-use in Timor
Authors: J. Leslie Keedy, Gisela Menger, Christian Heinlein
Venue: Proceedings of the Fortieth International Conference on Tools Pacific: Objects for internet, mobile and embedded applications (2002)

Unlike most object oriented programming languages Timor, which has been designed to support component development, replaces the class construct with separate constructs for defining types and their implementations (which are not types). It also distinguishes between behaviourally conforming subtyping and the inclusion of behaviourally deviant interfaces in the definition of derived types. The separation of types and implementations simplifies a separation of subtyping and subclassing, facilitating the re-use of implementations of one type to implement other, unrelated types. A further technique allows a type to be mapped onto an unrelated type with different method names, such that the latter's implementations can also be re-used to implement the former. The paper concludes by outlining a substantial example based on the Timor Collection Library.
