Stock market prediction with multiple classifiers
Authors: Bo Qian, Khaled Rasheed
Venue: Applied Intelligence (2007)

Stock market prediction is attractive and challenging. According to the efficient market hypothesis, stock prices should follow a random walk pattern and thus should not be predictable with more than about 50 percent accuracy. In this paper, we investigated the predictability of the Dow Jones Industrial Average index to show that not all periods are equally random. We used the Hurst exponent to select a period with great predictability. Parameters for generating training patterns were determined heuristically by auto-mutual information and false nearest neighbor methods. Some inductive machine-learning classifiers--artificial neural network, decision tree, and k-nearest neighbor were then trained with these generated patterns. Through appropriate collaboration of these models, we achieved prediction accuracy up to 65 percent.
Productivity simulation during the planning phase of the Glencoe tunnel in Calgary, Canada: a case study
Authors: Hussien T. AL-Battaineh, Simaan AbouRizk, James Tan, Siri Fernando
Venue: Proceedings of the 38th conference on Winter simulation (2006)

This paper discusses the Glencoe Storm Sewer Upgrade Project in Calgary, Alberta. The proposed tunnel is 2920mm in diameter, stretching along 27th Ave SW from 15th St SW to 20th St SW with a total length of 935m. Its depth varies from 16m at the working shaft to 42m at the retrieval shaft. The tunnel will reduce surface flooding by providing temporary storage of stormwater runoff during major storm events. The focus of this paper is project planning. The planning phase includes scope definition, contract setup, cost estimate, team assembly, equipment and material procurements, risk analysis, constructability review, geotechnical investigation, Safety and ECO Plan development, and scheduling and productivity simulations. The challenges presented in this project are the unfamiliarity with the local conditions and the uncertainty of the projected productivity and completion date of the project. Those issues were modeled and mitigation strategies were established using simulation technologies.
Some classical mathematical results related to the problems of the firmware/hardware interface
Authors: T. C. Wesselkamper
Venue: ACM SIGMICRO Newsletter (1975)

The paper reviews the Shannon and Reed-Muller Decomposition Theorems and notes the relationship of the former to machine instruction set. It hypothesizes an instruction set based on Galois field operations and applies the divided difference methods of Newton to the automatic generation of a polynomial representation of an arbitrary function. Some numeric results are given for the fields GF(9) and GF(16). An extension of the methods to the representation of functions by rational forms is suggested.

In silico grouping of peptide/HLA class I complexes using structural interaction characteristics
Authors: Joo Chuan Tong, Tin Wee Tan, Shoba Ranganathan
Venue: Bioinformatics (2007)

Motivation: Classification of human leukocyte antigen (HLA) proteins into supertypes underpins the development of epitope-based vaccines with wide population coverage. Current methods for HLA supertype definition, based on common structural features of HLA proteins and/or their functional binding specificities, leave structural interaction characteristics among different HLA supertypes with antigenic peptides unexplored. Methods: We describe the use of structural interaction descriptors for the analysis of 68 peptide/HLA class I crystallographic structures. Interaction parameters computed include the number of intermolecular hydrogen bonds between each HLA protein and its corresponding bound peptide, solvent accessibility, gap volume and gap index. Results: The structural interactions patterns of peptide/HLA class I complexes investigated herein vary among individual alleles and may be grouped in a supertype dependent manner. Using the proposed methodology, eight HLA class I supertypes were defined based on existing experimental crystallographic structures which largely overlaps (77% consensus) with the definitions by binding motifs. This mode of classification, which considers conformational information of both peptide and HLA proteins, provides an alternative to the characterization of supertypes using either peptide or HLA protein information alone.

Rapid and brief communication: Eliminating redundancy and irrelevance using a new MLP-based feature selection method
Authors: E. Gasca, J. S. Sánchez, R. Alonso
Venue: Pattern Recognition (2006)

This paper presents a novel feature selection method based on the use of a multilayer perceptron (MLP). The algorithm identifies a subset of relevant, non-redundant attributes for supervised pattern classification by estimating the relative contribution of the input units (those representing the attributes) to the output neurons (those corresponding to the problem classes). The experimental results suggest that the proposed method works well on a variety of real-world domains.
Analysis of the contention access period of IEEE 802.15.4 MAC
Authors: Iyappan Ramachandran, Arindam K. Das, Sumit Roy
Venue: ACM Transactions on Sensor Networks (TOSN) (2007)

The recent ratification of IEEE 802.15.4 PHY-MAC specifications for low-rate wireless personal area networks represents a significant milestone in promoting deployment of wireless sensor networks (WSNs) for a variety of commercial uses. The 15.4 specifications specifically target wireless networking among low-rate, low-power and low-cost devices that is expected to be a key market segment for a large number of WSN applications. In this article, we first analyze the performance of the contention access period specified in the IEEE 802.15.4 standard in terms of throughput and energy consumption. This analysis is facilitated by a modeling of the contention access period as nonpersistent CSMA with backoff. We show that, in certain applications in which having an inactive period in the superframe may not be desirable due to delay constraints, shutting down the radio between transmissions provides significant savings in power without significantly compromising the throughput. We also propose and analyze the performance of a modification to the specification which could be used for applications in which MAC-level acknowledgements are not used. Extensive ns-2 simulations are used to verify the analysis.

Effective Parametric Estimation of Non-Gaussian Autoregressive Moving Average Processes Exhibiting Noise with Impulses
Authors: Preston D. Frazier, M. F. Chouikha
Venue: Journal of VLSI Signal Processing Systems (2006)

In statistical signal processing, parametric modeling of non-Gaussian processes experiencing noise interference is a very important research topic. Particularly challenging to some researchers is how to estimate signals encountering stochastic noise process exhibiting sharp spikes. The authors propose the use of systems with impulse effect along with the classic autoregressive moving average model as a novel parametric modeling tool to successfully estimate these specific processes. The proficiency of this original system is illustrated in a performance table.
Symmetric Discharge Logic against Differential Power Analysis
Authors: Jong Suk Lee, Jae Woon Lee, Young Hwan Kim
Venue: IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences (2007)

Differential power analysis (DPA) is an effective technique that extracts secret keys from cryptographic systems through statistical analysis of the power traces obtained during encryption and decryption operations. This letter proposes symmetric discharge logic (SDL), a circuit-level countermeasure against DPA, which exhibits uniform power traces for every clock period by maintaining a set of discharge paths independent of input values. This feature minimizes differences in power traces and improves resistance to DPA attacks. HSPICE simulations for the test circuits using 0.18 μm TSMC CMOS process parameters indicate that SDL reduces power differences by an order of magnitude, compared to the existing circuit-level technique.
Moving digital libraries into the student learning space: The GetSmart experience
Authors: Byron B. Marshall, Hsinchun Chen, Rao Shen, Edward A. Fox
Venue: Journal on Educational Resources in Computing (JERIC) (2006)

The GetSmart system was built to support theoretically sound learning processes in a digital library environment by integrating course management, digital library, and concept mapping components to support a constructivist, six-step, information search process. In the fall of 2002 more than 100 students created 1400 concept maps as part of selected computing classes offered at the University of Arizona and Virginia Tech. Those students conducted searches, obtained course information, created concept maps, collaborated in acquiring knowledge, and presented their knowledge representations. This article connects the design elements of the GetSmart system to targeted concept-map-based learning processes, describes our system and research testbed, and analyzes our system usage logs. Results suggest that students did in fact use the tools in an integrated fashion, combining knowledge representation and search activities. After concept mapping was included in the curriculum, we observed improvement in students' online quiz scores. Further, we observed that students in groups collaboratively constructed concept maps with multiple group members viewing and updating map details.
Tandem repeats over the edit distance
Authors: Dina Sokol, Gary Benson, Justin Tojeira
Venue: Bioinformatics (2007)

Motivation: A tandem repeat in DNA is a sequence of two or more contiguous, approximate copies of a pattern of nucleotides. Tandem repeats occur in the genomes of both eukaryotic and prokaryotic organisms. They are important in numerous fields including disease diagnosis, mapping studies, human identity testing (DNA fingerprinting), sequence homology and population studies. Although tandem repeats have been used by biologists for many years, there are few tools available for performing an exhaustive search for all tandem repeats in a given sequence. Results: In this paper we describe an efficient algorithm for finding all tandem repeats within a sequence, under the edit distance measure. The contributions of this paper are two-fold: theoretical and practical. We present a precise definition for tandem repeats over the edit distance and an efficient, deterministic algorithm for finding these repeats. Availability: The algorithm has been implemented in C++, and the software is available upon request and can be used at http://www.sci.brooklyn.cuny.edu/~sokol/trepeats. The use of this tool will assist biologists in discovering new ways that tandem repeats affect both the structure and function of DNA and protein molecules. Contact: sokol@sci.brooklyn.cuny.edu
Independence of certain quantities indicating subword occurrences
Authors: Arto Salomaa
Venue: Theoretical Computer Science (2006)

When words are characterized in terms of numerical quantities, awkward considerations due to the noncommutativity of words are avoided. The numerical quantity investigated in this paper is |w|u, the number of occurrences of a word u as a (scattered) subword of a word w. Parikh matrices recently introduced have these quantities as their entries. According to the main result in this paper, no entry in a Parikh matrix, no matter how high the dimension, can be computed in terms of the other entries. Consequences concerning various inference problems between numbers |w|u themselves, as well as of the word w from these numbers, are obtained.
The use of theatre in requirements gathering and usability studies
Authors: A. F. Newell, A. Carmichael, M. Morgan, A. Dickinson
Venue: Interacting with Computers (2006)

This paper discusses the use of theatrical techniques to communicate to designers the user requirements for IT interfaces - particularly those of ''extreme users'' such as older people. The methodology and processes of producing such material in a video form are described, together with the strengths and weaknesses of this approach. The paper concludes by suggesting the various roles live theatre can play in user centered design. Although the research, on which this paper is based, focuses on the challenges presented by older and disabled users, the techniques described are applicable to a wider range of users.
ISIS: interaction sites identified from sequence
Authors: Yanay Ofran, Burkhard Rost
Venue: Bioinformatics (2007)

Motivation: Large-scale experiments reveal pairs of interacting proteins but leave the residues involved in the interactions unknown. These interface residues are essential for understanding the mechanism of interaction and are often desired drug targets. Reliable identification of residues that reside in protein--protein interface typically requires analysis of protein structure. Therefore, for the vast majority of proteins, for which there is no high-resolution structure, there is no effective way of identifying interface residues. Results: Here we present a machine learning-based method that identifies interacting residues from sequence alone. Although the method is developed using transient protein--protein interfaces from complexes of experimentally known 3D structures, it never explicitly uses 3D information. Instead, we combine predicted structural features with evolutionary information. The strongest predictions of the method reached over 90% accuracy in a cross-validation experiment. Our results suggest that despite the significant diversity in the nature of protein--protein interactions, they all share common basic principles and that these principles are identifiable from sequence alone.

A synthesizable datapath-oriented embedded FPGA fabric
Authors: Steve J. E. Wilton, C. H. Ho, Philip H. W. Leong, Wayne Luk, Brad Quinton
Venue: Proceedings of the 2007 ACM/SIGDA 15th international symposium on Field programmable gate arrays (2007)

We present an architecture for a synthesizable datapath-oriented Field Programmable Gate Array (FPGA) core which can be used to provide post-fabrication flexibility to a System-on-Chip (SoC). Our architecture is optimized for bus-based operations that are common in signal processing and computation intensive applications. It employs a directional routing architecture, which allows it to be synthesized using standard ASIC design tools and flows. We also describe a proof-of-concept layout of our core. It is shown that the proposed architecture is significantly more area efficient than the best previously reported synthesizable programmable logic core.
A new efficient simulation strategy for pricing path-dependent options
Authors: Gang Zhao, Yakun Zhou, Pirooz Vakili
Venue: Proceedings of the 38th conference on Winter simulation (2006)

The purpose of this paper is twofold. First, it serves to describe a new strategy, called Structured Database Monte Carlo (SDMC), for efficient Monte Carlo simulation. Its second aim is to show how this approach can be used for efficient pricing of path-dependent options via simulation. We use efficient simulation of a sample of path-dependent options to illustrate the application of SDMC. Extensions to other path-dependent options are straightforward.
