Modelling Behaviour Cycles for Life-Long Learning in Motivated Agents
Authors: Kathryn Merrick
Venue: Proceedings of the 7th International Conference on Simulated Evolution and Learning (2008)

Natural systems such as plants, animals and humans exhibit behaviour that forms distinct, rhythmic cycles. These cycles permit individuals and societies to learn, adapt and evolve in complex, dynamic environments. This paper introduces a model of behaviour cycles for artificial systems. This model provides a new way to conceptualise and evaluate life-long learning in artificial agents. The model is demonstrated for evaluating the sensitivity of motivated reinforcement learning agents. Results show that motivated reinforcement learning agents can learn behaviour cycles that are relatively robust to changes in motivation parameters.
A case for adaptable applications software
Authors: Mary Woodward, Peter F. DiGiammarino
Venue: Proceedings of the May 16-19, 1983, national computer conference (1983)

Contemporary economic circumstances have sent many organizations that extend consumer credit scrambling to secure automated support for collection operations. The traditional alternatives, custom system development and packaged software, fall far short of being acceptable to most large credit-oriented organizations. The Computer Assisted Collection System (CACS) was originally developed as a custom system and has since been used as adaptable foundation software by many large organizations to secure essentially customized support at a fraction of the cost, time, and risk that would normally be required. This paper reports on the success of the use of adaptive software to fill this urgent need and lends credence to the theory that throughout the 1980s there will be a trend towards the use of adaptive software to meet business' demands for low-risk, low-cost, fully functional and tailored software.
Design and Evaluation of a Multimedia Integrated Parallel File System
Authors: Alexey Roytman, Israel Ben-Shaul, Israel Cidon
Venue: Proceedings of the 1999 IEEE International Conference on Multimedia Computing and Systems - Volume 02 (1999)

This paper shows the design of MiPFS, a parallel file system intended to be used as a low-level platform to develop more complex I/O entities on top of it. This parallel file system relays on the idea that the user should execute I/O operations using the data-types stored on each object, so that each file can be managed as an typed object. However, as we want to provide only mechanism, and not policies, MiPFS includes functions to manage fixed and variable length records, and their associated indexes. This approach, and the quality of service functionality, allows to use MiPFS as a continuous media parallel file system.
Identification of Piecewise Linear Uniform Motion Blur
Authors: Karn Patanukhom, Akinori Nishihara
Venue: IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences (2008)

A motion blur identification scheme is proposed for non-linear uniform motion blurs approximated by piecewise linear models which consist of more than one linear motion component. The proposed scheme includes three modules that are a motion direction estimator, a motion length estimator and a motion combination selector. In order to identify the motion directions, the proposed scheme is based on a trial restoration by using directional forward ramp motion blurs along different directions and an analysis of directional information via frequency domain by using a Radon transform. Autocorrelation functions of image derivatives along several directions are employed for estimation of the motion lengths. A proper motion combination is identified by analyzing local autocorrelation functions of non-flat component of trial restored results. Experimental examples of simulated and real world blurred images are given to demonstrate a promising performance of the proposed scheme.

Search-order coding method with indicator-elimination property
Authors: Chin-Chen Chang, Yung-Chen Chou, Yi-Pei Hsieh
Venue: Journal of Systems and Software (2009)

Vector quantization (VQ) is a widely used technique for many applications especially for lossy image compression. Since VQ significantly reduces the size of a digital image, it can save the costs of storage space and image delivery. Search-order coding (SOC) was proposed for improving the performance of VQ in terms of compression rate. However, SOC requires extra data (i.e. indicators) to indicate source of codewords so the compression rate may be affected. To overcome such a drawback, in this paper, a search-order coding with the indicator-elimination property was proposed by using a technique of reversible data hiding. The proposed method is the first one using such a concept of data hiding to achieve a better compression rate of SOC. From experimental results, the performance of the SOC method can be successfully improved by the proposed indicator eliminated search-order coding method in terms of compression rate. In addition, compared with other relevant schemes, the proposed method is also more flexible than some existing schemes.
LC3uArch: a graphical simulator of the LC-3 microarchitecture
Authors: Andrew Brownfield, Cindy Norris
Venue: ACM SIGCSE Bulletin (2009)

The small instruction set size of the LC-3 as well as its similarities to more powerful instruction sets make it an ideal hypothetical machine for introductory computer science and computer engineering students. Several tools are available for working with this hypothetical machine including simulators, and assemblers for various platforms. We have created an additional tool, LC3uArch, that is useful for debugging LC-3 programs like the existing simulators, but unlike existing simulators also helps student to develop an understanding of the LC-3 microarchitecture. The results of a student survey on the use of LC3uArch indicate our students find LC3uArch a valuable learning tool.
End user developer: friend or foe?
Authors: Mike Montgomery, Dwight D. Daniel
Venue: Journal of Computing Sciences in Colleges (2009)

Today, in many organizations, end user developers and I/T departments are at loggerheads, accepting neither the advantages nor the capabilities of the other. End user developers create fast but unique applications normally without expandability. I/T departments create "proper" applications but with long development cycles that possibly do not address the needs of the user. Neither talks to the other. This adversarial role creates hard feelings and inefficiencies, with the user in the middle. This paper will categorize each group and then delve into the advantages and disadvantages of each. Once each group's capability is understood, organizations can use both to their best advantages. Finally, this paper gives a methodology to control the directions of each group for a common good.
Start with the Most Difficult Part
Authors: Diomidis Spinellis
Venue: IEEE Software (2009)

The process of putting together wpl, a small system that extends arbitrary Web pages with links to Wikipedia entries, demonstrates the value of being able to choose between bottom-up versus top-down design and implementation. By starting our work with the most difficult task, we ensure that we'll face the fewest possible constraints and therefore have the maximum freedom to tackle it. This approach allows the early shrinking of the project's cone of uncertainty, while ensuring that we undertake it with a beginner's enthusiasm and motivation. We can also apply the principle when ordering elements of the software life cycle: requirements elicitation, high- and low-level design, coding, debugging, testing, and maintenance.
Development of a dolphin robot: structure, sensors, actuators, and user interactions
Authors: Daejung Shin, Seung Y. Na, Soon-Ki Yoo
Venue: Proceedings of the 8th conference on Signal, Speech and image processing (2008)

We introduce a dolphin robot that acts like a dolphin in terms of autonomous swimming and human-dolphin interactions. Body structures, sensors and actuators, governing microcontroller boards, swimming and interaction features are described for a typical entertainment dolphin robot. Actions of mouth-opening, tail splash or water blow through a spout hole are the typical responses of interaction when touch sensors on its body detect users' demand. A pair of microphones as the ears of a dolphin robot, in order to improve the entertainment dolphin robot's ability to interact with people, is used to estimate the peak sound directions from surrounding viewers. Dolphin robots should turn towards people who demand to interact with them, while swimming autonomously.
The Efficiency Variations of Chinese Feed-processing Enterprise of Different Ownership Structures: 2002-2005
Authors: Aimin Wang
Venue: Proceedings of the 2009 Second International Workshop on Knowledge Discovery and Data Mining (2009)

In terms of the DEA-based SBM model and the performances between 2002-2005, the comprehensive technical efficiency, pure technical efficiency and scale efficiency of Chinese feed-processing industry of seven types of ownership structures were evaluated in the paper, respectively. It is shown that our conclusions are consistent with the research results on ownership and efficiency of other industries, as reported by other researchers. That is, the comprehensive technical efficiency, pure technical efficiency and scale efficiency of state-owned enterprises are all lower than those of the non-state-owned enterprises. Of the seven types of enterprises with different ownership structures, cooperative enterprises have the highest the comprehensive technical efficiency, while state-owned enterprises have the lowest efficiency. The efficiency of cooperative enterprises is three times as high as that of the state-owned enterprises. Except private enterprises, the comprehensive technical efficiencies of all types of feed-processing industry increase with time, while that of private enterprises has large fluctuations over the years. The variation of pure technical efficiency almost follows that of the comprehensive technical efficiency. In comparison, the scale efficiencies of the feed-processing industry are relatively high. State-owned enterprises still have the lowest scale efficiency.
Diastolic arrays: throughput-driven reconfigurable computing
Authors: Myong Hyon Cho, Chih-Chi Cheng, Michel Kinsy, G. Edward Suh, Srinivas Devadas
Venue: Proceedings of the 2008 IEEE/ACM International Conference on Computer-Aided Design (2008)

Diastolic arrays are arrays of processing elements that communicate exclusively through First-In First-Out (FIFO) queues. FIFO virtualization units enable relaxed timing of data transfers, and include hardware support to guarantee bandwidth and buffer space for all data transfers, which may follow composite paths through the network. We show that the architecture of diastolic arrays enables efficient synthesis from high-level specifications of communicating finite state machines so average throughput is maximized. Preliminary results are presented on an H.264 decoding benchmark.
SCRABBLE.GZ: A Web-Based Collaborative Game to Promote the Galician Language
Authors: Guillermo de Bernardo, Ana Cerdeira-Pena, Oscar Pedreira, Ángeles S. Places, Diego Seco
Venue: Proceedings of the 2009 Second International Conferences on Advances in Computer-Human Interactions (2009)

We present in this paper a web-based version of a Scrabble game, describing its architecture and some implementation details. This architecture makes possible a high degree of interactivity, so that the players perceive the game as being played in real-time. Furthermore, no client-side plug-in or applet isused. These properties are achieved by means of a carefully designed architecture that uses AJAX (Asynchronous JavaScript and XML) for data exchange. This architecture guarantees low load on the server, so complex computations relative to the game logic can be done in real-time. Moreover, data structures and algorithms were designed to efficiently access a custom Galician dictionary, which supports the game functionalities. We show in this paper how this data structures and algorithms provide an efficient method to create a Scrabble move generation algorithm. We also show how the combination of these with the architecture proposed provides a fully interactive web application that can handle complex calculations over a very large lexicon with real-time appearance.

An English-language processing system that "learns" about new domains
Authors: Bruce W. Ballard, John C. Lusth
Venue: Proceedings of the May 16-19, 1983, national computer conference (1983)

We are developing an English-language processing system called LDC with emphasis upon (a) small- or medium-sized office domains, as opposed to large relationalstyle databases; (b) mechanisms to learn about new domains and the English to be used in discussing them; and (c) capabilities for deep semantic processing, for example where English inputs can be phrased naturally, not merely as a notational variant for complete, formal queries. LDC consists of two major components and an external retrieval module. The first component, which we call "Prep," obtains information about a new domain and the language to be used in discussing it. The second, "user-phase," component of LDC resembles an ordinary NL processor, but (a) most decisions are determined from the preprocessed information appearing in the data files produced by Prep, and (b) the emphasis is upon the semantics of "layered" domains, described herein. In this paper we (1) present the motivation behind LDC; (2) summarize and give examples of the behavior of Prep; (3) provide an overview of the user-phase component; and (4) give examples of current and projected capabilities of the system.
A Model for Enhancing Knowledge Creation, Application, and Succession While Facilitating Leadership Change within Virtual Work Environments
Authors: Michael Charles Hitson
Venue: Proceedings of the 2009 International Conference on Information, Process, and Knowledge Management (2009)

This document posits an approach for leaders to gain advantage through knowledge facilitation within virtual work environments and presents a leadership model, the Knowledge Founded Virtual Self-Management Model (KFVSM). The model addresses the leadership of virtual teams as self-management founded and to operate within a soft systems structure. A proactive leadership structure incorporating environmental scanning founded on a dynamic fulcrum provides the superstructure of the model. The model was developed in reaction to increasing virtual work environments incorporating high levels of information technology within dynamic markets demanding quick change.The model operates from a knowledge facilitation platitude. Multiple contextual factors from the organization and follower perspective are incorporated. The model is meant to propagate organization paradigm shifts rather than just providing a method to react to them. Lastly, the KFVSM embraces leadership learning, change, and growth and views leadership as a skill to be developed over time and in reaction to change, knowledge, and need.
Geometry and Effort in Gestural Renderings of Musical Sound
Authors: Rolf Inge Godøy
Venue: Gesture-Based Human-Computer Interaction and Simulation: 7th International Gesture Workshop, GW 2007, Lisbon, Portugal, May 23-25, 2007, Revised Selected Papers (2009)

As may be seen at concerts and in various everyday listening situations, people often make spontaneous gestures when listening to music. We believe these gestures are interesting to study because they may reveal important features of musical experience. In particular, hand movements may give us information on what features are perceived as salient by listeners. Based on various current ideas on embodied cognition, the aim of this paper is to argue that gestures are integral to music perception, and to present research in support of this. A conceptual model of separating geometry and effort is presented in order to better understand the variety of music-related gestures we may observe, leading up to some ideas on how to apply this conceptual model in present and future research.

At its instantiation the instrument establish a socket connection with a specialized server, gets the task's definition, places facilities at student's disposal to express task's decision and trace and records in a database all students activity during his/her interaction with the instrument. The records are used for students' assessment and form students' models. The instrument is realized as a Java applet. It has been used in the education of future computer, communication and electronic engineers at Rousse University "A. Kanchev".
Towards a Self-structured Grid: An Ant-Inspired P2P Algorithm
Authors: Agostino Forestiero, Carlo Mastroianni, Giuseppe Papuzzo, Giandomenico Spezzano
Venue: Transactions on Computational Systems Biology X (2008)

This paper introduces Antares, a bio-inspired algorithm that exploits ant-like agents to build a P2P information system in Grids. The work of agents is tailored to the controlled replication and relocation of metadata documents that describe Grid resources. These descriptors are indexed through binary strings that can either represent topics of interest, specifically in the case that resources are text documents, or be the result of the application of a locality preserving hash function, that maps similar resources into similar keys. Agents travel the Grid through P2P interconnections and, by the application of ad hoc probability functions, they copy and move descriptors so as to locate descriptors represented by identical or similar keys into neighbor Grid hosts. The resulting information system is here referred to as self-structured, because it exploits the self-organizing characteristics of ant-inspired agents, and also because the association of descriptors to hosts is not pre-determined but easily adapts to the varying conditions of the Grid. This self-structured organization combines the benefits of both unstructured and structured P2P information systems. Indeed, being basically unstructured, Antares is easy to maintain in a dynamic Grid, in which joins and departs of hosts can be frequent events. On the other hand, the aggregation and spatial ordering of descriptors can improve the rapidity and effectiveness of discovery operations, and also enables range queries, which are beneficial features typical of structured systems.
