Modeling Federal Funds rates: a comparison of four methodologies
Authors: A. G. Malliaris, Mary Malliaris
Venue: Neural Computing and Applications (2009)

Monthly Federal Fund interest rate values, set by the Federal Open Market Committee, have been the subject of much speculation prior to the announcement of their new values each period. In this study we use four competing methodologies to model and forecast the behavior of these short term Federal Fund interest rates. These methodologies are: time series, Taylor, econometric and neural network. The time series forecasts use only past values of Federal Funds rates. The celebrated Taylor rule methodology theorizes that the Federal Fund rate values are influenced solely by deviations from a desired level of inflation and from potential output. The econometric and neural network models have inputs used by both the time series and Taylor rule. Using monthly data from 1958 to the end of 2005 we distinguish between sample and out-of-sample sets to train, evaluate, and compare the models&#x2019; effectiveness. Our results indicate that the econometric modeling performs better than the other approaches when the data are divided into two sets of pre-Greenspan and Greenspan periods. However, when the data sample is divided into three groups of low, medium and high Federal Funds, the neural network approach does best.
Stabilization of oscillations from a monoparametric family of the autonomous system
Authors: I. N. Barabanov, V. N. Tkhai
Venue: Automation and Remote Control (2009)

The problem of oscillation stabilization is solved for the autonomous system in the case when the oscillations form a monoparametric family. For each possible point type of the family the explicit formulae that solve the problem are obtained. It follows from those formulae that the dissipation is a necessary condition of the stabilization. The obtained sufficient conditions of the stabilizations coinside with the appropriate necessary conditions to within the sign of unstrict inequality.
A Network Coloring Game
Authors: Kamalika Chaudhuri, Fan Chung Graham, Mohammad Shoaib Jamall
Venue: Proceedings of the 4th International Workshop on Internet and Network Economics (2008)

We analyze a network coloring game which was first proposed by Michael Kearns and others in their experimental study of dynamics and behavior in social networks. In each round of the game, each player, as a node in a network G, uses a simple, greedy and selfish strategy by choosing randomly one of the available colors that is different from all colors played by its neighbors in the previous round. We show that the coloring game converges to its Nash equilibrium if the number of colors is at least two more than the maximum degree. Examples are given for which convergence does not happen with one fewer color. We also show that with probability at least 1&thinsp;&minus;&thinsp;&delta;, the number of rounds required is O(log(n/&delta;)).

Naive programmer problems with specification of transfer-of-control
Authors: Lance A. Miller
Venue: Proceedings of the May 19-22, 1975, national computer conference and exposition (1975)

We have conducted a series of experiments concerning the programming performance of persons with no prior contact with computers other than the training received in the experimental sessions. Our objective in these experiments is to identify design principles for facilitating communication between the naive user, as a problem solver, and a computer system. We view programming as a problem-solving activity, an instance of what generally may be called "procedure specification." We believe it possible to design computers as optimal problem-solving tools only if the operating characteristics of the problem solvers are known and taken into account. Consequently, we are seeking to discover the problems and processes involved in human specification of procedures, using experimental laboratory methods.
SPA: a smart phone assisted chronic illness self-management system with participatory sensing
Authors: Kewei Sha, Guoxing Zhan, Weisong Shi, Mark Lumley, Clairy Wiholm, Bengt Arnetz
Venue: Proceedings of the 2nd International Workshop on Systems and Networking Support for Health Care and Assisted Living Environments (2008)

The medical system has not been able to effectively adapt to the dramatic transformation in public health challenges; from acute to chronic and lifestyle-related illnesses. Although acute illnesses can be treated successfully in an office or hospital, chronic illnesses comprise the bulk of health care needs and require a very different approach. There is overwhelming consensus that the prevention and treatment of cardiovascular disease, diabetes, hypertension, chronic pain, obesity, asthma, HIV, and many other chronic illnesses require substantial patient self-management [2].

Multimedia traffic routing
Authors: Dan Mancas, Ecaterina-Irina Manole, Nicolae-Iulian Enescu
Venue: Proceedings of the 8th conference on Applied computer scince (2008)

In this paper, an analysis of the distributions of traffic capacity is made. Problems that arise in routing are treated, each presented in different scenarios in order to obtain a result in comparing different topologies. The comparison analysis is pursuing obtaining a result over the performance of the network. After that, the topology effect is presented. As conclusions, solutions for the presented scenarios and also for other important scenarios are given. In all these algorithms the time problem was not yet consider until now, so the average execution time is finally analyzed.
Gen-Adler: the Generalized Adler's equation for injection locking analysis in oscillators
Authors: Prateek Bhansali, Jaijeet Roychowdhury
Venue: Proceedings of the 2009 Asia and South Pacific Design Automation Conference (2009)

Injection locking analysis based on classical Adler's equation is limited to LC oscillators as it is dependent on quality factor. In this paper, we present the Generalized Adler's equation applicable for injection locking analysis on oscillators independent of the circuit topology. The equation is obtained by averaging the PPV phase macromodel. The procedure is considerably simple and handy to determine the locking range for arbitrary shape small AC injection signal. Analytical equations for injection locking dynamics are formulated using the Generalized Adler's equation and validated with the PPV simulations.
Comparison of bees algorithm, ant colony optimisation and particle swarm optimisation for PID controller tuning
Authors: Karl O. Jones, André Bouffet
Venue: Proceedings of the 9th International Conference on Computer Systems and Technologies and Workshop for PhD Students in Computing (2008)

Evolutionary Computation (EC) is a vibrant area of investigation, with some of the least widely known approaches being Ant Colony Optimisation, Particle Swarm Optimisation and Bees Algorithm, all of which can be used in optimisation problems. This paper makes a comparison of the effectiveness of the three methods on a particular optimisation problem, namely the tuning of the parameters for a PID controller.
Identifying Phenotypes and Genotypes: A Case Study Evaluating an In-Car Navigation System
Authors: Georgios Papatzanis, Paul Curzon, Ann Blandford
Venue: Engineering Interactive Systems: EIS 2007 Joint Working Conferences, EHCI 2007, DSV-IS 2007, HCSE 2007, Salamanca, Spain, March 22-24, 2007. Selected Papers (2008)

There are a range of different usability evaluation methods: both analytical and empirical. The appropriate choice is not always clear, especially for new technologies. In-car navigation systems are an example of how multimodal technologies are increasingly becoming part of our everyday life. Their usability is important, as badly designed systems can induce errors resulting in situations where driving safety may be compromised. In this paper we use a study on the usability of a navigation device when the user is setting set up an itinerary to investigate the scope of different classes of approach. Four analytical and one empirical techniques were used to evaluate the usability of the device. We analyse the results produced by the two classes of approach --- analytical versus empirical --- and compare them in terms of their diversity and the insight they provide to the analyst in respect to the overall usability of the system and its potential improvement. Results suggest a link between genotypes and the analytical class of approach and phenotypes in the empirical class of approach. We also illustrate how the classes of approach complement each other, providing a greater insight into the usability of a system.
Efficient Node Overlap Removal Using a Proximity Stress Model
Authors: Emden R. Gansner, Yifan Hu
Venue: Graph Drawing: 16th International Symposium, GD 2008, Heraklion, Crete, Greece, September 21-24, 2008. Revised Papers (2009)

When drawing graphs whose nodes contain text or graphics, the nontrivial node sizes must be taken into account, either as part of the initial layout or as a post-processing step. The core problem is to avoid overlaps while retaining the structural information inherent in a layout using little additional area. This paper presents a new node overlap removal algorithm that does well by these measures.
A Stochastic Epidemiological Model and a Deterministic Limit for BitTorrent-Like Peer-to-Peer File-Sharing Networks
Authors: George Kesidis, Takis Konstantopoulos, Perla Sousi
Venue: Network Control and Optimization: Second Euro-NF Workshop, NET-COOP 2008 Paris, France, September 8-10, 2008. Revised Selected Papers (2009)

We propose a stochastic model for a file-sharing peer-to-peer network which resembles the popular BitTorrent system: large files are split into chunks and a peer can download or swap from another peer only one chunk at a time. We exhibit the fluid and diffusion limits of a scaled Markov model of this system and look at possible uses of them to draw practical conclusions.

The clique-separator graph for chordal graphs
Authors: Louis Ibarra
Venue: Discrete Applied Mathematics (2009)

We present a new representation of a chordal graph called the clique-separator graph, whose nodes are the maximal cliques and minimal vertex separators of the graph. We present structural properties of the clique-separator graph and additional properties when the chordal graph is an interval graph, proper interval graph, or split graph. We also characterize proper interval graphs and split graphs in terms of the clique-separator graph. We present an algorithm that constructs the clique-separator graph of a chordal graph in O(n^3) time and of an interval graph in O(n^2) time, where n is the number of vertices in the graph.
Application of artificial neural networks to stylometric analysis
Authors: Urszula Stanczyk, Krzysztof A. Cyran
Venue: Proceedings of the 8th conference on Systems theory and scientific computation (2008)

Stylometric analysis of a literary text can comprise several elements and its aims include authorship attribution, author characterisation and similarity detection, which fall within the scope of information retrieval tasks. Author identification is a problem of significant importance not only from academic or historic point of view as in cases of disputed authorship of some literary works (even Shakespeare's) but in more current and sinister affairs of forensic nature. To deal with these problems various methodologies have been employed or invented, and in the paper there is presented the application of Artificial Neural Networks as the processing engine for authorship analysis.
Policy-Driven Negotiations and Explanations: Exploiting Logic-Programming for Trust Management, Privacy & Security
Authors: Piero A. Bonatti, Juri L. Coi, Daniel Olmedilla, Luigi Sauro
Venue: Proceedings of the 24th International Conference on Logic Programming (2008)

Traditional protection mechanisms rely on the characterization of requesters by identity. This is adequate in a closed system with a known set of users but it is not feasible in open environments such as the Web, where parties may get in touch without being previously known to each other. In such cases policy-driven negotiation protocols have emerged as a possible solution to enforce security on future web applications. Along with this setting, we illustrate Protune, a system for specifying and cooperatively enforcing security and privacy policies (as well as other kinds of policies). Protune relies on logic programming for representing policies and for reasoning with and about them.
An Effective Edge Detection Methodology for Medical Images Based on Texture Discrimination
Authors: Sivaram V. Thangam, Sai Deepak K., Harikrishna Rai G.N., Pranav Prabhakar Mirajkar
Venue: Proceedings of the 2009 Seventh International Conference on Advances in Pattern Recognition (2009)

As medical images are fuzzy, edge detection based on texture characteristics is comparatively effective than intensity based techniques. A new methodology is described for texture edge detection in medical images that is applicable across modalities. We use a multi-scale filter to capture texture edge information. An experimental prototype based on the proposed methodology provides a test bed for comparison with a popular edge detection technique.
Customer Value Assessment with Interval Numbers Based on Max-Entropy and TOPSIS
Authors: Quan Zhang, TieYuan Yin, Wei Jia
Venue: Proceedings of the 2009 Second International Workshop on Knowledge Discovery and Data Mining (2009)

This paper proposes an approach to customer value assessment based on Max-Entropy and TOPSIS, while customers’ information are interval numbers. The decision matrix in the form of interval is normalized and transformed into a definite one based on maximizing the entropy of the decision matrix; The weights of attributes are then determined, which are used in assessing the alternatives based on TOPSIS. An example is used to illustrate the proposed approach
Harnessing parallel disks to solve Rubik's cube
Authors: Daniel Kunkle, Gene Cooperman
Venue: Journal of Symbolic Computation (2009)

The number of moves required to solve any configuration of Rubik's cube has held a fascination for over 25 years. A new upper bound of 26 is produced. More important, a new methodology is described for finding upper bounds. The novelty is two-fold. First, parallel disks are employed. This allows 1.4x10^1^2 states representing symmetrized cosets to be enumerated in seven terabytes. Second, a faster table-based multiplication is described for symmetrized cosets that attempts to keep most tables in the CPU cache. This enables the product of a symmetrized coset by a generator at a rate of 10 million moves per second.
Security through Diversity: Leveraging Virtual Machine Technology
Authors: Daniel Williams, Wei Hu, Jack W. Davidson, Jason D. Hiser, John C. Knight, Anh Nguyen-Tuong
Venue: IEEE Security and Privacy (2009)

Biologists have long recognized the dangers of the lack of diversity or monocultures in biological systems. Recently, it has been noted that much of the fragility of our networked computing systems can be attributed to the lack of diversity or monoculture of our software systems. The problem is severe. Because it is virtually inevitable that software will ship with flaws, our software monoculture leaves systems open to large-scale attacks by knowledgeable adversaries. Inspired by the resilience of diverse biological systems, the authors developed the Genesis Software Development Toolchain. An innovative aspect of Genesis is the use of an application-level virtual machine technology that enables the application of diversity transforms at any point in the software toolchain. Using Genesis, they authors demonstrated that diversity, when judiciously applied, is a practical and effective defense against two widely used types of attacks—return-to-libc and code injection.

This paper presents the analytical solution for the radiation by axial slots array antenna on a nonconfocal dielectric-coated elliptic cylinder. The analysis is based on the eigen function technique and the addition theorem of Mathieu functions. The excited apertures are assumed to generate a TM polarized wave. Calculated azimuthal radiation patterns are presented for different antenna and coating parameters.
An Improved Upward Planarity Testing Algorithm and Related Applications
Authors: Sarmad Abbasi, Patrick Healy, Aimal Rextin
Venue: Proceedings of the 3rd International Workshop on Algorithms and Computation (2009)

We consider the standard algorithm to test the upward planarity of embedded digraphs by Bertolazzi et al.[3]. We show how to improve its running time from O(n + r 2) to $O(n+r^{\frac{3}{2}})$, where r is the number of sources and sinks in the digraph. We also discuss 2 applications of this technique: finding a certificate of correctness of an implementation of our upward planarity testing algorithm; and improving the running time of getting a quasi-upward planar drawing for an embedded digraph with minimum number of bends.
An Intrinsic Framework for Analysis of Facial Surfaces
Authors: Chafik Samir, Anuj Srivastava, Mohamed Daoudi, Eric Klassen
Venue: International Journal of Computer Vision (2009)

A statistical analysis of shapes of facial surfaces can play an important role in biometric authentication and other face-related applications. The main difficulty in developing such an analysis comes from the lack of a canonical system to represent and compare all facial surfaces. This paper suggests a specific, yet natural, coordinate system on facial surfaces, that enables comparisons of their shapes. Here a facial surface is represented as an indexed collection of closed curves, called facial curves, that are level curves of a surface distance function from the tip of the nose. Defining the space of all such representations of face, this paper studies its differential geometry and endows it with a Riemannian metric. It presents numerical techniques for computing geodesic paths between facial surfaces in that space. This Riemannian framework is then used to: (i) compute distances between faces to quantify differences in their shapes, (ii) find optimal deformations between faces, and (iii) define and compute average of a given set of faces. Experimental results generated using laser-scanned faces are presented to demonstrate these ideas.
