Alfresco Developer Guide
Authors: Jeff Potts
Venue:  (2008)

Alfresco is an open source platform for Enterprise Content Management solutions. ECM includes things like Document Management, Web Content Management, Collaboration/Enterprise 2.0, Digital Asset Management, Records Management, and Imaging. At its core is a repository for rich content like documents, web assets, XML, and multimedia. The repository is surrounded by a services layer (supporting both SOAP and REST) that makes getting content into and out of the repository a breeze, which is why so many next generation Internet solutions are built on Alfresco. Implementing Alfresco usually involves extending the repository to accommodate your business-specific metadata and business logic. These extensions are done using some combination of Java, JavaScript, XML, and FreeMarker. This book takes you through a set of exercises as if you were rolling out and customizing the platform for a fictional organization called SomeCo, which wants to roll out Alfresco enterprise-wide. Each department has a set of requirements that need addressed. We will show you how to extend Alfresco to meet these requirements. By the time you've worked through the entire book, you will be familiar with the entire platform. You'll be prepared to make your own customizations whether they are part of a Document Management solution, a web site that uses Alfresco for content storage, or an entire custom application built on Alfresco's REST API. This book will give you the knowledge and confidence you need to make Alfresco do what you need it to do. Appoach This book focuses on teaching by example. Every chapter provides a bit of an overview, and then dives right in to hands-on examples so you can see and play with the solution in your own environment. All code samples run on both the latest Enterprise and Labs release. Audience This book will be most useful to developers who are writing code to customize Alfresco for their organization or who are creating custom applications that sit on top of Alfresco. This book is for Java developers, and you will get most from the book if you already work with Java but you need not have prior experience on Alfresco. Although Alfresco makes heavy use of open source frameworks such as Spring, Hibernate, JavaServer Faces, and Lucene, no prior experience using these is assumed.
I am my robot: the impact of robot-building and robot form on operators
Authors: Victoria Groom, Leila Takayama, Paloma Ochi, Clifford Nass
Venue: Proceedings of the 4th ACM/IEEE international conference on Human robot interaction (2009)

As robots become more pervasive, operators will develop richer relationships with them. In a 2 (robot form: humanoid vs. car) x 2 (assembler: self vs. other) between-participants experiment (N=56), participants assembled either a humanoid or car robot. Participants then used, in the context of a game, either the robot they built or a different robot. Participants showed greater extension of their self-concept into the car robot and preferred the personality of the car robot over the humanoid robot. People showed greater self extension into a robot and preferred the personality of the robot they assembled over a robot they believed to be assembled by another. Implications for the theory and design of robots and human-robot interaction are discussed.
Using slithers of simulation in a new approach for intelligent initialization of non-terminating systems
Authors: Philip G. Brabazon
Venue: Proceedings of the 40th Conference on Winter Simulation (2008)

Reduction and even avoidance of the initial transient is known to be possible using intelligent initialization but it is not an approach that has been actively researched for some time. Using ideas from complexity science and informed by the recently developed equation-free technique a new method for identifying initializing conditions is developed. Many short bursts of simulation, called slithers, are used to construct the dynamic function of a system. Importantly, the function reveals the point attractor of the dynamic system to which it will evolve and the conditions at the attractor define the initializing conditions for future simulation runs. The method is demonstrated by application to a queuing network.
The plasma free space optical model for ubiquitous systems
Authors: Brian J. d'Auriol, Yu Niu, Sungyoung Lee, Young-Koo Lee
Venue: Proceedings of the 3rd International Conference on Ubiquitous Information Management and Communication (2009)

The Plasma Model for free space-based optical communication in ubiquitous systems is proposed. The Plasma Model provides various operations including dispersion, redirection, retransmission, unicast, multicast and broadcast in potentially long distance sector regions. Details of the model are presented and discussed including technology feasibility. Applications to distributed algorithm development and cluster spacecraft/satellite systems are described. Advantages and disadvantages with typical Radio Frequency based communication are also presented. Collectively, we show that our model, though simple, is an effective alternative to develop a system that compares favorably with either conventional RF wireless systems, or, with other free space optical systems that require precise calculation of receiver locations.

Authors: Zheng Yue-feng, Ma Wei-feng
Venue: Proceedings of the 3rd WSEAS international conference on Computer engineering and applications (2009)

Along with the development of education, it becomes more important to issue and gain the education information day by day. According to the education information's characteristic, we can change the single attribute query type to a better one which can satisfies the requirement of education information service through using the Web Geographic Information System(WebGIS). This paper proposes a new design for education information service platform based on WebGIS, and analyses the key technologies including MapXtreme's basic work principle, the architecture and so on. At the same time, this paper introduces service platform's function, data structure and ASP implementation method of MapXtreme in detail.
DisCo: Distributed Co-clustering with Map-Reduce: A Case Study towards Petabyte-Scale End-to-End Mining
Authors: Spiros Papadimitriou, Jimeng Sun
Venue: Proceedings of the 2008 Eighth IEEE International Conference on Data Mining (2008)

Huge datasets are becoming prevalent; even as researchers, we now routinely have to work with datasets that are up to a few terabytes in size. Interesting real-world applications produce huge volumes of messy data. The mining process involves several steps, starting from pre-processing the raw data to estimating the final models. As data become more abundant, scalable and easy-to-use tools for distributed processing are also emerging. Among those, Map-Reduce has been widely embraced by both academia and industry. In database terms, Map-Reduce is a simple yet powerful execution engine, which can be complemented with other data storage and management components, as necessary. In this paper we describe our experiences and findings in applying Map-Reduce, from raw data to final models, on an important mining task. In particular, we focus on co-clustering, which has been studied in many applications such as text mining, collaborative filtering, bio-informatics, graph mining. We propose the Distributed Co-clustering (DisCo) framework, which introduces practical approaches for distributed data pre-processing, and co-clustering. We develop DisCo using Hadoop, an open source Map-Reduce implementation. We show that DisCo can scale well and efficiently process and analyze extremely large datasets (up to several hundreds of gigabytes) on commodity hardware.
Variable weight risk management model for IT services
Authors: Mahmoud Z. Iskandarani, Gahleb A. El-Refae
Venue: Proceedings of the 8th conference on Systems theory and scientific computation (2008)

The important part that Information Technology services play controlling risks in assets management is discussed. The effect of level of threat on running IT resources is modeled and explained with a new parameter called the Rust Factor (RF), which measures readiness of resources and services in comparison to existing threats. The extent of human contribution to risk management is also explained with emphasis on level of trust, confidence and skill level.
Note: Finding a tree structure in a resolution proof is NP-complete
Authors: Jan Hoffmann
Venue: Theoretical Computer Science (2009)

The resolution tree problem consists of deciding whether a given sequence-like resolution refutation admits a tree structure. This paper shows the NP-completeness of both the resolution tree problem and a natural generalization of the resolution tree problem that does not involve resolution.
On the decreasing significance of large standard cells in technology mapping
Authors: Jae-sun Seo, Igor L. Markov, Dennis Sylvester, David Blaauw
Venue: Proceedings of the 2008 IEEE/ACM International Conference on Computer-Aided Design (2008)

Technology scaling reduces gate delays while wire delays may increase. Our work studies the interaction of this phenomenon with technology mapping and its impact on modern EDA flows. In particular, we demonstrate that the use of larger standard cells increases the number of long wires and may undermine circuit delay optimization at 65nm and below. Experiments with 130nm, 90nm, 65nm, and 45nm industrial CMOS technology suggest that limiting the use of larger standard cells in technology mapping becomes more effective at 65nm and 45nm node, resulting in up to 12% improvement in critical path delay on large benchmark circuits.

Authors: Aybars Uğur, Doğan Aydin
Venue: Advances in Engineering Software (2009)

Traveling salesman problem (TSP) is one of the extensively studied combinatorial optimization problems and tries to find the shortest route for salesperson which visits each given city precisely once. Ant colony optimization (ACO) algorithms have been used to solve many optimization problems in various fields of engineering. In this paper, a web-based simulation and analysis software (TSPAntSim) is developed for solving TSP using ACO algorithms with local search heuristics. Algorithms are tested on benchmark problems from TSPLIB and test results are presented. Importance of TSPAntSim providing also interactive visualization with real-time analysis support for researchers studying on optimization and people who have problems in form of TSP is discussed.
Optimal Shot Boundary Detection Based on Robust Statistical Models
Authors: Alan Hanjalic, HongJiang Zhang
Venue: Proceedings of the 1999 IEEE International Conference on Multimedia Computing and Systems - Volume 02 (1999)

This paper presents a novel statistical framework for the optimal shot boundary detection based on minimization of the average detection error probability. The required statistical functions are modeled using a robust metric for visual content discontinuities (based on motion compensation) and by taking into account the knowledge about the shot length distribution and visual discontinuity patterns at shot boundaries. Major advantages of the proposed framework are its robust and by far sequence independent detection performance, as well as the possibility for simultaneously detecting different types of shot boundaries.
Mechanized information flow analysis through inductive assertions
Authors: Warren A. Hunt,  Jr., Robert Bellarmine Krug, Sandip Ray, William D. Young
Venue: Proceedings of the 2008 International Conference on Formal Methods in Computer-Aided Design (2008)

We present a method for verifying information flow properties of software programs using inductive assertions and theorem proving. Given a program annotated with information flow assertions at cutpoints, the method uses a theorem prover and operational semantics to generate and discharge verification conditions. This obviates the need to develop a verification condition generator (VCG) or a customized logic for information flow properties. The method is compositional: a subroutine needs to be analyzed once, rather than at each call site. The method is being mechanized in the ACL2 theorem prover, and we discuss initial results demonstrating its applicability.
Online fuzzy modeling with structure and parameter learning
Authors: Wen Yu, Xiaoou Li
Venue: Expert Systems with Applications: An International Journal (2009)

This paper describes a novel nonlinear modeling approach with fuzzy rules and support vector machines. Structure identification is realized by an online clustering method and fuzzy support vector machines, the fuzzy rules are generated automatically. Time-varying learning rates are applied for updating the membership functions of the fuzzy rules. The modeling errors are proven to be robustly stable with bounded uncertainties by a Lyapunov method and an input-to-state stability technique. Comparisons with other related works are made through an application of gas furnace process. The results demonstrate that our approach has good accuracy, and this method is suitable for online fuzzy modeling.
A multiprocessor description language
Authors: William T. Overman, Stephen D. Crocker, Vittal Kini
Venue: Proceedings of the May 4-7, 1981, national computer conference (1981)

A language for describing multiprocessor systems is presented. The language, called MPDL, provides a flexible and unambiguous model of concurrency and allows for hierarchical construction of concurrent systems. MPDL encourages the user to encapsulate interprocess synchronization and communication in a special component called a connector. This encapsulation helps facilitate multilevel modeling and abstraction of communication protocols. A simulator for the language has been implemented and is running at ISI. This paper describes MPDL and evaluates the language in terms of two examples.
Fault tolerant file models for parallel file systems: introducing distribution patterns for every file
Authors: A. Calderón, F. García-Carballeira, L. M. Sánchez, J. D. García, J. Fernandez
Venue: The Journal of Supercomputing (2009)

Parallelism in file systems is obtained by using several independent server nodes supporting one or more secondary storage devices. This approach increases the performance and scalability of the system, but a fault in one single node can stop the whole system. To avoid this problem, data must be stored using some kind of redundant technique, so any data stored in a faulty element can be recovered. Fault tolerance can be provided in I/O systems by using replication or RAID based schemes. However, most of the current systems apply the same technique for all files in the system.This paper describes the fault tolerance support provided by Expand, a parallel file system based on standard servers. This support can be applied to other parallel file systems with many benefices: fault tolerance at file level, flexible definition of fault tolerance scheme to be used, possibility to change the fault tolerant support used for a file, etc.
To Determine the Weight in a Weighted Sum Method for Domain-Specific Keyword Extraction
Authors: Wenshuo Liu, Wenxin Li
Venue: Proceedings of the 2009 International Conference on Computer Engineering and Technology - Volume 01 (2009)

Keyword extraction has been a very traditional topic in Natural Language Processing. However, most methods have been too complicated and slow to be applied in real applications, for example in web-based system. This paper proposes an approach which will complete some preparing works focusing on exploring the linguistic characteristics of a specific domain. This part can be completed once and for all and thus reduce the burden in the real extraction process. It is a weighted sum method and the preparing work focus on finding out the weight. Once we have the weight, the extraction can be completed by addition, multiplication and sort, which are quite simple for modern computer. Experimental results show the effectiveness of the proposed approach.
The effect of design parameters on single-event upset sensitivity of MOS current mode logic
Authors: Mahta Haghi, Jeff Draper
Venue: Proceedings of the 19th ACM Great Lakes symposium on VLSI (2009)

In this paper, we describe and discuss the effects of design parameters such as transistor size, output voltage swing and bias current on radiation sensitivity of MOS current mode logic (MCML) type sequential elements that are used in high-speed communication systems. We have implemented latches and flip-flops in 90 nm technology and show how single-event upset can be mitigated just by adjusting particular design factors at the same clock frequency. It is shown that the critical charge needed to upset the logic state of a sequential element increases up to 5 times by increasing the bias current at the cost of more power and up to 2 times by increasing output voltage swing at the cost of more area. The effect of changing operation frequency from 500MHz to 4GHz on single-event upset is also investigated. For frequencies higher than 2 GHz, critical charge improves 1.3 times.
Estimating the measuring sensitivity of unipolar and bipolar ECG with lead field method and FDM models
Authors: Merja Puurtinen, Jari Viik, Noriyuki Takano, Jaakko Malmivuo, Jari Hyttinen
Venue: Computer Methods and Programs in Biomedicine (2009)

New portable electrocardiogram (ECG) measurement systems are emerging into market. Some use nonstandard bipolar electrode montage and sometimes very small interelectrode distances to improve the usability of the system. Modeling could provide a straightforward method to test new electrode systems. The aim of this study was to assess whether modeling the electrodes' measuring sensitivity with lead field method can provide a simple tool for testing a number of new electrode locations. We evaluated whether the actual ECG signal strength can be estimated by lead fields with two realistic 3D finite difference method (FDM) thorax models. We compared the modeling results to clinical body surface potential map (BSPM) data from 236 normal patients and studied 117 unipolar and 42 bipolar leads. In the case of unipolar electrodes the modeled measuring sensitivities correlated well with the clinical data (r=0.86, N=117, p <0.05). In the case of bipolar electrodes the correlation was moderate (r=0.62 between Model 1 and clinical data, r=0.71 between Model 2 and clinical data, N=42 and p <0.05 for both). Based on this we can conclude that lead field analysis based on realistic thorax models provides a good initial prediction for designing new electrode montages and measurement systems.

Venue: Proceedings of the May 6-10, 1974, national computer conference and exposition (1974)

Rapidly changing technology is affecting every aspect of computer graphic systems. Basically, a computer graphic system consists of an interface/display processor, function generators, display, operator input/output devices, and software. Each element will be briefly described as an introduction for subsequent speakers who will discuss technology impact on the elements. Tradeoff considerations among the various elements will also be discussed.
Computing full disjunction using COJO
Authors: T. V. Vijay Kumar, Atul Shridhar, Aloke Ghoshal
Venue: Information Technology and Management (2009)

The Internet has provided users with access to wealth of information available on the Web, a considerable amount of which is semi-structured. In recent times, there has grown a need to access this information in an interpretable and meaningful way. One way to access this information is by transforming it into relations and integrating the relations to arrive at a universal relation thus ensuring simple and powerful searching of the underlying semi-structured data. Several operations exist for integrating these relations, like outer union, natural inner join, natural outer join etc., of which natural outer join has been found to be most effective in terms of achieving meaningful results i.e. full disjunction of the relations. Since natural outer join is non-associative, for more than two relations only some of the natural outer join ordering may lead to full disjunction. The Correct Outer Join Ordering (COJO) strategy proposed in this paper computes such natural outer join ordering of relations leading to full disjunction. It is further shown that the natural outer join ordering of relations produced by algorithm COJO compares well with the well-known algorithm SOJO on performance parameters.
A New Model for Simulating Multiple Uncorrelated Mobile-to-Mobile Rayleigh Fading Waveforms
Authors: Huogen Yu, Lidong Zhu
Venue: Proceedings of the 2009 WRI International Conference on Communications and Mobile Computing - Volume 01 (2009)

To produce multiple uncorrelated mobile-to-mobile Rayleigh fading waveforms is often required for simulating frequency selective mobile-to-mobile channels, multiple-input multiple-output (MIMO) mobile-to-mobile channels, and diversity-combined mobile-to-mobile channels. In this paper, a new deterministic model based on Rice’s sum of sinusoids (SoS) is proposed to guarantee the uncorrelationbetween different simulated Mobile-to-Mobile Rayleigh fading waveforms. Analytical and numerical results show that the resulting sum-of-sinusoids-based deterministic model fulfills all main requirements imposed by the reference model with given correlation properties derived under two-dimensional isotropic scattering conditions.
Reflections on the role of seeding in social design
Authors: Penny Hagen, John MacFarlane
Venue: Proceedings of the 20th Australasian Conference on Computer-Human Interaction: Designing for Habitus and Habitat (2008)

In strategies that make use of social software participation not only defines success but also defines the design. This foregrounds particular considerations during the planning and design process about participation, and how we bridge the gap between the client vision, the project and the potential community of contributors or users. This paper introduces and reflects on the notion of seeding as a construct useful for emphasising and exploring ways to promote or increase the likelihood of successful engagement. In systems that are determined by participation, it is our position that part of our role as designers is to facilitate or seed that participation and that the act of seeding (participation) becomes a core design activity. In this paper we reflect through case studies on the significance and potential for seeding content, connection and community through our design work, and on the way this has affected our approach to and understanding of the design process.
