Designing learner-controlled educational interactions based on learning/cognitive style and learner behaviour
Authors: Kyparisia A. Papanikolaou, Andrew Mabbott, Susan Bull, Maria Grigoriadou
Venue: Interacting with Computers (2006)

Recently, research in individual differences and in particular, learning and cognitive style, has been used as a basis to consider learner preferences in a web-based educational context. Modelling style in a web-based learning environment demands that developers build a specific framework describing how to design a variety of options for learners with different approaches to learning. In this paper two representative examples of educational systems, Flexi-OLM and INSPIRE, that provide learners a variety of options designed according to specific style categorisations, are presented. Experimental results from two empirical studies performed on the systems to investigate learners' learning and cognitive style, and preferences during interaction, are described. It was found that learners do have a preference regarding their interaction, but no obvious link between style and approaches offered, was detected. Derived from an examination of this experimental data, we suggest that while style information can be used to inform the design of learning environments that accommodate learners' individual differences, it would be wise to recommend interactions based on learners' behaviour. Learning environments should allow learners or learners' interaction behaviour to select or trigger the appropriate approach for the particular learner in the specific context. Alternative approaches towards these directions are also discussed.
Relative Entropy-Based Filtering of Internet Worms by Inspecting TCP SYN Retry Packets
Authors: Byungseung Kim, Saewoong Bahk
Venue: Proceedings of the 21st International Conference on Advanced Information Networking and Applications Workshops - Volume 01 (2007)

Although many defense techniques against scanning worms have been developed, they have difficulty in ingress filtering if the incoming scanning traffic has insufficient intensity, which is usually the case. To make matters worse, legitimate Internet services behaving like worms and dynamic network environments undermines the efficacy of the techniques. In this paper, we propose a simple and efficient defense algorithm against Internet scanning worms that has high detection rate and low false positive rate. Our defense algorithm observes the protocol behavior of TCP SYN retries and applies a relative entropy scheme, which is used for measuring the distance between two distributions, to process the collected information. It builds up the black-list to isolate detected hosts from the Internet, and adjusts related parameters adaptively according to the observed traffic. Moreover, it acquires the simplicity and effectiveness at the ingress point only by inspecting SYN retry on a unidirectional link, which makes the defense mechanism easily applicable to a network. Against real-life traces, we investigate the performance of our algorithm and compare it with that of SNORT. The results manifest clearly that our algorithm outperforms the rate-based detection technique in terms of detection rate, detection speed and false positive rate.
Modeling the short-term dynamics of packet losses
Authors: Fernando Silveira, Edmundo de Souza e Silva
Venue: ACM SIGMETRICS Performance Evaluation Review (2006)

Packet loss models play an essential role in computer networks analysis. Performance evaluation studies often abstract the loss and delay characteristics of a path or network with a single end-to-end analytical model. This model should be able to represent the characteristics of the path and accurately reproduce the impact of delay and losses on the studied protocol while keeping complexity low.
Determinants of adoption of high speed data services in the business market: evidence for a combined technology acceptance model with task technology fit model
Authors: Margherita Pagani
Venue: Information and Management (2006)

This paper presents a Business-Oriented Model of Factors that affect the adoption of wireless High Speed Data Services (HSDS). We reviewed business IT acceptance literature and developed an explorative survey of a sample of twelve companies in Europe and USA. From this, a theoretical model was created and hypotheses were formulated. Data were then collected on a sample of 1545 companies in USA and Europe. Based on these results, we developed a model that combined the key ideas of both TAM and TTF and showed that both were necessary in predicting wireless High Speed Data Service adoption.

IBM Websphere V5 Edge of Network Patterns (Websphere Software)
Authors: Vinodha Ramanujam, Byron Braswell
Venue:  (2003)

Runtime Patterns with Caching Proxy and Tivoli Access Manager User authentication and authorization Runtime node placement guidelines Security is such a fundamental enabler of e-busines that in the emerging business-to-consumer (B2C) and business-to-business (B2B) markets, effective security can make the difference betwen being successful and becoming an “also ran”. The promise of e-business and its ability to create new revenue streams is predicated on the ability of these new business processes to reach these new markets and customers. That promise can evaporate if security issues are not addressed up front. This IBM Redbook addresses the security issues of user authentication and authorization using the concept of Patterns. Patterns for e-business are a group of proven, reusable assets that can help speed the process of developing applications. In this redbook, we describe guidelines and options for the selection of Runtime patterns that include user authentication and authorization considerations in the design process. Specifically, we address software and node configuration scenarios within the demilitarized zone (DMZ) and give examples of implementation procedures.
Language support for fast and reliable message-based communication in singularity OS
Authors: Manuel Fähndrich, Mark Aiken, Chris Hawblitzel, Orion Hodson, Galen Hunt, James R. Larus, Steven Levi
Venue: ACM SIGOPS Operating Systems Review (2006)

Message-based communication offers the potential benefits of providing stronger specification and cleaner separation between components. Compared with shared-memory interactions, message passing has the potential disadvantages of more expensive data exchange (no direct sharing) and more complicated programming.In this paper we report on the language, verification, and run-time system features that make messages practical as the sole means of communication between processes in the Singularity operating system. We show that using advanced programming language and verification techniques, it is possible to provide and enforce strong system-wide invariants that enable efficient communication and low-overhead software-based process isolation. Furthermore, specifications on communication channels help in detecting programmer mistakes early---namely at compile-time---thereby reducing the difficulty of the message-based programming model.The paper describes our communication invariants, the language and verification features that support them, as well as implementation details of the infrastructure. A number of benchmarks show the competitiveness of this approach.

Process prioritization using output production: Scheduling for multimedia
Authors: Yoav Etsion, Dan Tsafrir, Dror G. Feitelson
Venue: ACM Transactions on Multimedia Computing, Communications, and Applications (TOMCCAP) (2006)

Desktop operating systems such as Windows and Linux base scheduling decisions on CPU consumption; processes that consume fewer CPU cycles are prioritized, assuming that interactive processes gain from this since they spend most of their time waiting for user input. However, this doesn't work for modern multimedia applications which require significant CPU resources. We therefore suggest a new metric to identify interactive processes by explicitly measuring interactions with the user, and we use it to design and implement a process scheduler. Measurements using a variety of applications indicate that this scheduler is very effective in distinguishing between competing interactive and noninteractive processes.
Pseudopalindrome closure operators in free monoids
Authors: Aldo de Luca, Alessandro de Luca
Venue: Theoretical Computer Science (2006)

We consider involutory antimorphisms ϕ of a free monoid A* and their fixed points, called ϕ-palindromes or pseudopalindromes. A ϕ-palindrome reduces to a usual palindrome when ϕ is the reversal operator. For any word w ∈ A* the right (resp. left) ϕ-palindrome closure of w is the shortest ϕ-palindrome having w as a prefix (resp. suffix). We prove some results relating ϕ-palindrome closure operators with periodicity and conjugacy, and derive some interesting closure properties for the languages of finite Sturmian and episturmian words. In particular, a finite word w is Sturmian if and only if both its palindromic closures are so. Moreover, in such a case, both the palindromic closures of w share the same minimal period of w. A new characterization of finite Sturmian words follows, in terms of periodicity and special factors of their palindromic closures. Some weaker results can be extended to the episturmian case. By using the right ϕ-palindrome closure, we extend the construction of standard episturmian words via directive words. In this way one obtains a family of infinite words, called ϕ-standard words, which are morphic images of episturmian words, as well as a wider family of infinite words including the Thue-Morse word on two symbols.

Distributed Functions of DB2 for Z/OS and Os/390 (IBM Redbooks)
Authors: Bart Steegmans
Venue:  (2003)

Setting up your DDF environment Analyzing DDF performance Advanced topics: Thread pooling, sysplex support, and HiperSockets When DB2's Distributed Data Facility (DDF) was announced in the late eighties, it was looked at by many people as a nice gadget, but not something anybody would use in a real OLTP production environment. Distributed database access and DB2's DDF have come a long way since. DDF is now a full-function transaction monitor, using a highly efficient database interoperability protocol (DRDA) equipped with thread pooling and connection management that allows it to support very large networks. In this IBM Redbook we describe how to set up your DDF environment, and how to deploy the DDF capabilities in different configurations, including how to develop applications that access distributed databases. We also describe a set of more advanced features, such as thread pooling, and high availability distributed configurations, in a DB2 data sharing environment. We also demonstrate the advantages of using HiperSockets with DB2 for z/OS and OS/390 and DB2 Connect for zLinux. As performance and problem analysis are very important in today's production environments with applications demanding subsecond response times and zero down time, the publication also discusses the traces available to you to do performance monitoring and problem determination. We hope that after reading this publication you will have a better view of a wide range of functions that DDF has to offer, and say "Wow, I had no idea that I could do all of this with DDF!"

Stereovision depth analysis by two-dimensional motion charge memories
Authors: José M. López-Valles, Miguel A. Fernández, Antonio Fernández-Caballero
Venue: Pattern Recognition Letters (2007)

Several strategies to retrieve depth information from a sequence of images have been described so far. In this paper a method that turns around the existing symbiosis between stereovision and motion is introduced; motion minimizes correspondence ambiguities, and stereovision enhances motion information. The central idea behind our approach is to transpose the spatially defined problem of disparity estimation into the spatial-temporal domain. Motion is analyzed in the original sequences by means of the so-called permanency effect and the disparities are calculated from the resulting two-dimensional motion charge maps. This is an important contribution to the traditional stereovision depth analysis, where disparity is got from the image luminescence. In our approach, disparity is studied from a motion-based persistency charge measure.
