Digital management and retrieval of physical documents
Authors: Matthew Jervis, Masood Masoodian
Venue: Proceedings of the 3rd International Conference on Tangible and Embedded Interaction (2009)

Although in today's everyday work environments digital and paper documents co-exist, the systems used to manage them are often completely separate; digital documents are managed using computer systems, while paper documents are organised and managed using manual systems. Since it is unlikely that the widespread use of paper documents will cease to exist in the foreseeable future, digital systems are needed for managing the storage and retrieval of paper documents which better integrate with existing systems for management of digital documents. This paper presents an architecture for a system to digitally manage paper document containers, such as folders, which has been used as the design basis for a prototype system we have developed. This prototype system aims to resolve some of the problems associated with an earlier prototype we have developed to integrate filing of physical folders with digital document management systems.

Authors: Harun Resit Yazgan, Semra Boran, Kerim Goztepe
Venue: Expert Systems with Applications: An International Journal (2009)

An enterprise resource planning (ERP) software selection is known to be multi attribute decision making (MADM) problem. This problem has been modeled according with analytic network process (ANP) method due to fact that it considers criteria and sub criteria relations and interrelations in selecting the software. Opinions of many experts are obtained while building ANP model for the selection ERP then opinions are reduced to one single value by methods like geometric means so as to get desired results. To use ANP model for the selection of ERP for a new organization, a new group of expert's opinions are needed. In this case the same problem will be in counter. In the proposed model, when ANP and ANN models are setup, an ERP software selection can be made easily by the opinions of one single expert. In that case calculation of geometric mean of answers that obtained from many experts will be unnecessary. Additionally the effect of subjective opinion of one single decision maker will be avoided. In terms of difficulty, ANP has some difficulties due to eigenvalue and their limit value calculation. An ANN model has been designed and trained with using ANP results in order to calculate ERP software priority. The artificial neural network (ANN) model is trained by results obtained from ANP. It seems that there is no any major difficulty in order to predict software priorities with trained ANN model. By this results ANN model has been come suitable for using in the selection of ERP for another new decision.

Venue: Proceedings of the 2009 International Conference on Advanced Computer Control (2009)

The necessity of finding right skilled people, sharing resource and limitation on cost has made distributed software development indispensable. In a distributed development project, but are working collaboratively toward the outcome. Such offshore service providers follow the traditional process models. Agile practices promote development iterations, open collaboration, and process adaptability throughout the life cycle of the project. Adapting these practices in a distributed environment can help distributed development tackle the challenges of cultural incompatibility, leadership struggle and lack of trust. This paper describes the benefits of using Agile process and Scrum the iterative incremental process in Distributed Software development, and proposes two team structures for its implementation.

Authors: kanupriya Raturi, K. Susmitha Wils, Abhilash Mt
Venue: Proceedings of the 8th conference on Signal processing, computational geometry and artificial vision (2008)

The cancerous attaches, mainly the lung cancers, make a serious medical problem all over the world. The early diagnoses based on chest radiographs could notably lower its mortality. The efficiency of the computers gives the possibility to facilitate the work of the radiologists. In the first step the region of the interest, i.e. the lung field is determined and in the second step the lung nodules are identified. In this paper we describe a method for processing chest radiographs which segments the lung field and extracts a set of nodule candidate regions characterized by low cardinality and a high sensitivity ratio.
The research of online price quotation for the automobile parts exchange programme
Authors: S. G. Li, Y. L. Rong
Venue: International Journal of Computer Integrated Manufacturing (2009)

With the lack of virgin materials and the growing concerns for the environment, there has been an ever growing interest in reusing old products. In this paper, an online price quotation model (OPQM) for the 'exchange the new part with the old one' is proposed. The main aim of OPQM is to minimise the exchange price, based on jointly optimising the disassembly and remanufacturing plan for the used part throughout the supply chain. The disassembly and remanufacturing plan problem, however, resembles a combinatorial problem, whose computation time to obtain an optimal solution increases exponentially in proportion to the size of the problem. Therefore, the authors propose an enhanced particle swarm optimisation (EPSO) method to generate a relatively good solution within a given time. Through a series of experiments with several benchmark methods, the proposed EPSO method is found to be superior to the conventional optimisation methods, such as LINGO solver, in time, and preferable to the traditional particle swarm optimisation (PSO) and genetic algorithm (GA) in quality.
Relational Presentation: A Visually Interactive Approach
Authors: Robert Lane
Venue:  (2007)

Relational Presentation methods outlined in this book explore visually interactive PowerPoint presentation, where a speaker has dynamic, random access to hundreds, or even thousands, of visually rich slides while presenting. Instead of robotically advancing through a single linear slide show full of bullet points, he or she illustrates thoughts on-the-fly, answers audience questions with customized visual display, skips or adds material as appropriate, and otherwise sculpts messages to the needs of the moment- all while using standard PowerPoint software. Relational presenters approach an audience very differently compared to regular speakers. Their style is conversational, flexible, and responsive. This graduate-level, full-course textbook features hands-on exercises and more than 500 4-color illustrations. It also contains a link and password for downloading associated digital files and course resources. Learners immediately apply the methods to their own presentation materials, creating interlinked slide show structures that resemble Web sites, yet are formed exclusively with PowerPoint. This version of the textbook is compatible with PowerPoint 2003. A separate edition exists for PowerPoint 2007.
The Logic of Proofs as a Foundation for Certifying Mobile Computation
Authors: Eduardo Bonelli, Federico Feller
Venue: Proceedings of the 2009 International Symposium on Logical Foundations of Computer Science (2009)

We explore an intuitionistic fragment of Artëmov's Logic of Proofs as a type system for a programming language for mobile units. Such units consist of both a code and certificate component. Dubbed the Certifying Mobile Calculus, our language caters for both code and certificate development in a unified theory. In the same way that mobile code is constructed out of code components and extant type systems track local resource usage to ensure the mobile nature of these components, our system additionally ensures correct certificate construction out of certificate components. We present proofs of type safety and strong normalization for a run-time system based on an abstract machine.

JAID: An algorithm for data fusion and jamming avoidance on distributed sensor networks
Authors: Aristides Mpitziopoulos, Damianos Gavalas, Charalampos Konstantopoulos, Grammati Pantziou
Venue: Pervasive and Mobile Computing (2009)

Mobile Agent (MA) technology has been recently proposed in Wireless Sensor Networks (WSNs) literature to answer the scalability problem of client/server model in data fusion applications. In this paper, we describe the critical role MAs can play in the field of security and robustness of a WSN in addition to data fusion. The design objective of our Jamming Avoidance Itinerary Design (JAID) algorithm is twofold: (a) to calculate near-optimal routes for MAs that incrementally fuse the data as they visit the nodes; (b) in the face of jamming attacks against the WSN, to modify the itineraries of the MAs to bypass the jammed area(s) while not disrupting the efficient data dissemination from working sensors. If the number of jammed nodes is small, JAID only modifies the pre-jamming scheduled itineraries to increase the algorithm's promptness. Otherwise, JAID re-constructs the agent itineraries excluding the jammed area(s). Another important feature of JAID is the suppression of data taken from sensors when the associated successive readings do not vary significantly. Data suppression also occurs when sensors' readings are identical to those of their neighboring sensors. Simulation results confirm that JAID enables retrieval of information from the working sensors of partially jammed WSNs and verifies its performance gain over alternative approaches in data fusion tasks.
An attacker model for MANET routing security
Authors: Jared Cordasco, Susanne Wetzel
Venue: Proceedings of the second ACM conference on Wireless network security (2009)

Mobile ad-hoc networks are becoming ever more popular due to their flexibility, low cost, and ease of deployment. However, to achieve these benefits the network must employ a sophisticated routing protocol. Early proposed routing protocols were not designed to operate in the presence of attackers. There have been many subsequent attempts to secure these protocols, each with its own advantages and disadvantages. To allow for a comparison of these secure protocols, a single common attacker model is needed. Our first contribution in this work is to develop a comprehensive attacker model categorizing attackers based on their capabilities. This is in contrast to the existing models which seek to categorize attacks and then map that categorization back onto the attackers. Our second contribution is an analysis of the SAODV routing protocol using our new model, which demonstrates the structured approach inherent in our model and its benefits compared to existing work.
Proverbial wallet: tangible interface for financial awareness
Authors: John Kestner, Daniel Leithinger, Jaekyung Jung, Michelle Petersen
Venue: Proceedings of the 3rd International Conference on Tangible and Embedded Interaction (2009)

We propose a tangible interface concept for communicating personal financial information in an ambient and relevant manner. The concept is embodied in a set of wallets that provide the user with haptic feedback about personal financial metrics. We describe how such feedback can inform purchasing decisions and improve general financial awareness.
Advantages Of Evolutionary Computation Used For Exploration In The Creative Design Process
Authors: Peter von Buelow
Venue: Journal of Integrated Design Process Science (2007)

In early phases of design a wide exploration of the design space is crucial to the development of creative solutions. In this regard, Evolutionary Computation (EC), and in particular Genetic Algorithms, contain several qualities that can enhance exploration by opening the search process beyond the focus of finding a single "best" solution. Over the years many researchers in the area of creative thinking including Gordon, de Bono, Parnes, Osborn and others, have suggested design strategies that have interesting parallels in EC processes. For instance, a well known inhibitor of creative thinking is design fixation, where the suggestion of a particular solution makes it difficult to imagine other good solutions. Unlike many other computational search algorithms, EC methods work with populations of "fairly good" solutions. Therefore, there is less danger that creativity will be harmed by design fixation on one "best" solution. This paper shows through a specific example of a truss bridge how an EC based design exploration program can aid the designer by providing a selection of "pretty good" solutions rather than a single optimal solution. Other aspects of the EC program are also discussed including drawbacks to the method such as computational intensity as well as directions of future development.

A Simple On-Road Object Segmentation Approach in ITS System
Authors: Yongquan Xia, Jun Zhi, Min Huang, Weili Li, Rui Ma
Venue: Proceedings of the 2009 International Asia Conference on Informatics in Control, Automation and Robotics (2009)

In ITS(Intelligent Transportation System), on-road object detection algorithm is one of the most important research fields and obstacle segmentation is a key factor in obstacle detection approaches. In this paper, a simple and fast segmentation approach is proposed for on-road object in ITS. Firstly, a simple method is applied to detect the interest pixels in the transportation scene images by the defined interest pixels function and a single strategy is applied to reduce the redundant computation in the process of computation gray mean of pixels in squared window; Secondly, all the detected interest pixels neighbored each other are grouped to object interest region; after that, the non-interest pixels enclosed by interest region are changed as interest pixels; Lastly, the binarized images can be easily segmented applying simple edge detection algorithms or contour tracing approaches. Several images captured from ITS system is used to test the proposed algorithm, the result indicate that the approach is valid and feasible.
An analytical study of terahertz-waves measurements by ZnTe electro-optic crystal
Authors: Muhammad Siddique, Li Zhuo, Yang Suhui, Li Ping
Venue: Proceedings of the 6th conference on Microelectronics, nanoelectronics, optoelectronics (2007)

An analysis for intensity measurement of terahertz-waves generated by TPO and detection of the THz pulses occurs via free-space electro optic detection in ZnTe crystal has been carried out. The pump-probe technique has been used to observe the dynamics of an optically excited ZnTe electro-optic crystal. The THz pulses generated by TPO are 10-25 ns pulses at a repetition rate of 1 Hz. ZnTe crystal is being use for intensity measurement of THz-waves. In this theoretical proposed experiment, a short pump pulse (THz-wave) and probe pulse (near IR laser) with duration of typically 10 to 25 ns interacts in the ZnTe. In electro-optic sampling the two effects namely Pockels effect and Kerr effect have been discussed and interaction of two beams from or transmission through the ZnTe, the probe pulse Intensity contains information about the THz-waves' intensity and so on.
Hypergraph decomposition and secret sharing
Authors: Giovanni Di Crescenzo, Clemente Galdi
Venue: Discrete Applied Mathematics (2009)

A secret sharing scheme is a protocol by which a dealer distributes a secret among a set of participants in such a way that only qualified sets of them can reconstruct the value of the secret whereas any non-qualified subset of participants obtain no information at all about the value of the secret. Secret sharing schemes have always played a very important role for cryptographic applications and in the construction of higher level cryptographic primitives and protocols. In this paper we investigate the construction of efficient secret sharing schemes by using a technique called hypergraph decomposition, extending in a non-trivial way the previously studied graph decomposition techniques. A major advantage of hypergraph decomposition is that it applies to any access structure, rather than only structures representable as graphs. As a consequence, the application of this technique allows us to obtain secret sharing schemes for several classes of access structures (such as hyperpaths, hypercycles, hyperstars and acyclic hypergraphs) with improved efficiency over previous results. Specifically, for these access structures, we present secret sharing schemes that achieve optimal information rate. Moreover, with respect to the average information rate, our schemes improve on previously known ones. In the course of the formulation of the hypergraph decomposition technique, we also obtain an elementary characterization of the ideal access structures among the hyperstars, which is of independent interest.

Authors: Ming-hua Hsieh
Venue: Proceedings of the 40th Conference on Winter Simulation (2008)

Variable annuities are very appealing to the investor. For example, in United States, sales volume on variable annuities grew to a record 184 billion in calendar year 2006. However, due to their complicated payoff structure, their valuation and risk management are challenges to the insurers. In this paper, we study a variable annuity contract with cliquet options in Asia markets. The contact has quanto feature. We propose an efficient Monte Carlo method to value the contract. Numerical examples suggest our approach is quite efficient.
Effects of perspective elevation and environmental geometry on representation of a virtual room space
Authors: Zhiqiang Luo, Henry Been-Lirn Duh
Venue: Virtual Reality (2009)

The present study investigated how perspective elevation and room geometry influenced mental representation of spatial layout in virtual rooms. One virtual rectangular and one virtual cylindrical room were constructed. Subjects observed the spatial layout on the floor from five perspectives along the vertical dimension of each virtual room. Then they judged the direction of objects with respect to egocentric and canonical coordinates. The analysis of spatial judgment indicated that judgment accuracy of vertical direction decreased as the perspective elevated, while global situation awareness was best maintained at the 45&#x00b0; elevation angle. The effect of perspective elevation on judgment of horizontal direction was only found in the rectangular room. Moreover, subjects judged the relative direction between objects more quickly in the cylindrical room than in the rectangular room. Applications of these findings to virtual environment design were discussed.
Study of the positioning errors in a bidimensional horizontal strap-down inertial navigator generated by the inertial sensors
Authors: Teodor Lucian Grigorie, Nicolae Jula, Catalin Ioan Cepisca, Ciprian Racuciu
Venue: Proceedings of the 8th conference on Applied informatics and communications (2008)

The paper deals with the study of the influence of the inertial sensors errors on the position, speed and attitude of a bidimensional strap-down inertial navigation system in a horizontal plane. To test this influence we put up MATLAB/SIMULINK models for the acceleration and rotation sensors based on the sensors data sheets and on the IEEE equivalent models for the inertial sensors. The models can be used in the numerical simulation of the strap-down inertial navigation system, close by real conditions from the point of view of the distortions suffered by the useful acceleration and rotation signals at the passing through any type of accelerometers or gyros desired to be implemented in the navigator. These models have the advantage to work independent from each of the sensors' errors and thus to study their influence on the inertial navigator.
A Strong Designated-verifier Proxy Signature Scheme
Authors: Bo Zhang, Qiuliang Xu
Venue: Proceedings of the 2009 Second International Workshop on Knowledge Discovery and Data Mining (2009)

A strong designated-verifier proxy signature scheme was proposed to protect the original signer’s interests. In this scheme, the verifier was designated by the original signer. The valid proxy signature generated by the proxy signer on behalf of the original signer can only be accepted by the designated verifier and no body else can be convinced about the proxy signatures’ validity or invalidity even they get the private key of the verifier. So the holder of the signatures can’t misuse them even by leaking his private key. The scheme is proved secure under the CDH assumption in the random oracle model.
