How do consumers react to mobile marketing?
Authors: Kristina Heinonen, Tore Strandvik
Venue: Proceedings of the International Conference on Mobile Business (2006)

Digital marketing media, such as Internet and mobile phones, are considered to be powerful opportunities to reach consumers by allowing interactivity and personalization of the content and context of the message. This paper explores consumers' responsiveness to mobile marketing communication. We propose that consumer responsiveness is a function of the perceived relevance of the marketing message and the acceptance of the medium of receiving the message. Two empirical studies conducted in Finland showed that compared to traditional direct mail and commercial email, the responsiveness to mobile marketing was considerably lower. However, there were also consumers who welcome mobile marketing communication.

Authors: Kai-jian Liang, Quan Liang, Yang Yang
Venue: Proceedings of the First International Conference on Innovative Computing, Information and Control - Volume 1 (2006)

Quality of Service(QoS) support is a very important work in Service-oriented Grid system.The current ways to process QoS parameters is inefficient,even lead to a failure very easily. To solve these problems,the paper researched general QoS parameters,and put forward a new parameter called GSQN(Grid Service Quality Number) to depict the profile of qualitive characteristics of a grid service.Afterwards,a trategy of QoS parameters processing and a price model were presented in the paper,which can reduce the complexity of matchmaking process.The simulation was also accomplished, consequently, experimental data indicates a better performance and agrees with the final computation results.
A Scalable Architecture for On-Chip Compression: Options and Trade-Offs
Authors: Anis Uzzaman, Brion Keller, Vivek Chickermane
Venue: Proceedings of the 15th Asian Test Symposium (2006)

The increasing focus on better Quality of Silicon (QoS) and relentless pressure on the cost of test has brought on-chip test data compression technologies to the forefront. QoS considerations and device complexity have driven up the cost of test by the adoption of test methods that require significant higher test data volume, such as transition tests, to detect small delay defects. On-chip compression is then used to effectively reduce the cost of test by combining the deterministic nature of ATPG with the data compression capability of certain Logic BIST structures.

Authors: Han Qichang, Xie Jiancang, Wang Xiaohui, Si Yiming, Pan Yi
Venue: Proceedings of the 2006 International Conference on Hybrid Information Technology - Volume 01 (2006)

Along with the economical development, water pollution problem has been recognized increasingly. The paper discussed the coordinated development idea of water environment economy system by describing the Kuznets curve of environment quality and economical development. A coordinating model of water environment-economy-population composite system is built base on the multi-objects optimal thoughts and synergetic algorithm, which is used on Xiao-Hua region in the Yellow River. The calculation and analysis indicates that the coordinated development degree is unsatisfied in the last several years, but the total direction tends to harmony.
Design of Certificate Validation Protocol for On-line Financing Transaction using Virtual Identifier Information of Signer
Authors: Hyun-chul Kim, Jun-ho Choun, Moon-seog Jun
Venue: Proceedings of the 2006 International Conference on Hybrid Information Technology - Volume 01 (2006)

Certificate issued from certification authority can be revoked by a variety of reasons such as loss of private key, loss of qualification, and change of key. For such reasons, validation protocol of certificate, which can check status of certificate that is used in transactions on real-time basis, is required. The most generally protocols used these days are the use of the CRL(Certificate Revocation List) and the OCSP(Online Certificate Status Protocol). But the CRL can not give the real-time certificate status because the certificate is being delivered periodically, and the OCSP is structural concentration problem generated that one node handling all transactions. It will also take a long time to validate the certificate because each trade has to send mass information through the network. In this paper, we propose the protocol of real-time certificate validation that solves network overload and communication bottleneck by requesting certification using virtual identifier information of signer. Also, we confirm speed of certificate validation faster than existing CRL and OCSP protocol by test.

Multiscale Fusion of Visible and Thermal IR Images for Illumination-Invariant Face Recognition
Authors: Seong G. Kong, Jingu Heo, Faysal Boughorbel, Yue Zheng, Besma R. Abidi, Andreas Koschan, Mingzhong Yi, Mongi A. Abidi
Venue: International Journal of Computer Vision (2007)

This paper describes a new software-based registration and fusion of visible and thermal infrared (IR) image data for face recognition in challenging operating environments that involve illumination variations. The combined use of visible and thermal IR imaging sensors offers a viable means for improving the performance of face recognition techniques based on a single imaging modality. Despite successes in indoor access control applications, imaging in the visible spectrum demonstrates difficulties in recognizing the faces in varying illumination conditions. Thermal IR sensors measure energy radiations from the object, which is less sensitive to illumination changes, and are even operable in darkness. However, thermal images do not provide high-resolution data. Data fusion of visible and thermal images can produce face images robust to illumination variations. However, thermal face images with eyeglasses may fail to provide useful information around the eyes since glass blocks a large portion of thermal energy. In this paper, eyeglass regions are detected using an ellipse fitting method, and replaced with eye template patterns to preserve the details useful for face recognition in the fused image. Software registration of images replaces a special-purpose imaging sensor assembly and produces co-registered image pairs at a reasonable cost for large-scale deployment. Face recognition techniques using visible, thermal IR, and data-fused visible-thermal images are compared using a commercial face recognition software (FaceIt®) and two visible-thermal face image databases (the NIST/Equinox and the UTK-IRIS databases). The proposed multiscale data-fusion technique improved the recognition accuracy under a wide range of illumination changes. Experimental results showed that the eyeglass replacement increased the number of correct first match subjects by 85% (NIST/Equinox) and 67% (UTK-IRIS).
Policy Based Access Control in Dynamic Grid-based Collaborative Environment
Authors: Yuri Demchenko, Leon Gommans, Andrew Tokmakoff, Rene van Buuren
Venue: Proceedings of the International Symposium on Collaborative Technologies and Systems (2006)

This paper describes the design and development of a flexible, customer-driven, security infrastructure for Gridbased Collaborative Environments. The paper proposes further development of the access control model built around a service or resource provisioning agreement (e.g., an experiment or project) that is used as a basis for an instant access control policy definition and virtual association of users and resources. Workflow management technology is considered as a solution for dynamic security context management during the lifetime of an experiment. The paper analyses the required functionality and suggests extensions to the generic AAA Authorisation framework in order to support complex collaboration scenarios in dynamic virtualised environments. The paper provides implementation details on the use of XACML for fine-grained access control policy definition for complex resources and team-based role management, and SAML for secure credentials exchange. In addition, the paper discusses how the Virtual Organisations (VO) concept can be used for experiment-based dynamic security association management. The proposed technical solutions are intended to be compatible and interoperable with the current implementation of the Grid security middleware in the Globus Toolkit and gLite. The paper is based on experiences gained from major Grid-based and Gridoriented projects in collaborative applications and complex resource provisioning.
E-portfolios and Cross-Cultural Assessment
Authors: Johannes C. Cronje
Venue: Proceedings of the Sixth IEEE International Conference on Advanced Learning Technologies (2006)

It is difficult to collect evidence of adequate performance if an assessor and the assessees have different linguistic and cultural backgrounds. This paper considers three entries in student portfolios where the assessor tried to understand the students and their achievement, rather than to rate it. Three approaches were followed: positivist, post-structural /interpretive and feminist/holistic. Sources of data include artifacts produced by students for inclusion in the portfolio, assessment rubrics and assessment scores. Results indicate that portfolio assessment with criteria negotiated between the instructor/assessor, the learners and their peers allow for a rich thick evaluation that adds to the development of the learners. Detailed assessment rubrics stifled student creativity, while open-ended tasks with video feedback enhanced it. Further research needs to be conducted into standardizing the procedures of auditing assessments, rather than standardizing procedures of assessing.
Design of space-efficient, wide- and narrow transition-band, FIR filters
Authors: Xiaojuan Hu, L. S. DeBrunner, V. DeBrunner
Venue: Proceedings of the 2003 International Conference on Multimedia and Expo - Volume 1 (2003)

We propose a method for designing a filter to meet a set of specifications, which can be implemented with reduced area. Our approach combines a prefilter implementation structure whose function has been developed over the years with our previously reported variable precision technique for intelligently quantizing the filter coefficients. Our area-efficient structure uses frequency masking with a single filter model to give good performance with low order and low coefficient sensitivity. Our method does use a novel connection of a simple prefilter structure used in a frequency masking technique to give good designs for the previously unattainable wide-band filter designs. The technique also gives designs with superior (very sharp) transition regions. Both types produce filters that efficiently use digital circuitry, leading to space-efficient designs that are significantly smaller than would otherwise be the case. Some examples are given to demonstrate the effectiveness of our design.

Authors: Minjuan Wang, Jim Laffey, Tom Tupper, Paul Wangemann, Carl Harris
Venue: Proceedings of the 1999 conference on Computer support for collaborative learning (1999)

This paper describes experiences of youth and their mentors with authentic problem solving in an Internet-based Shared Environment for Expeditions (iExpeditions). The key questions examined are in what ways and to what extent do youth become engaged in an Expedition. First we examine parents&iacute; attitudes toward the iExpeditions project, and youth&iacute;s motivation for these online activities. Then we present the design for youths&iacute; first two-weeks of activities and then the reality of what occurred. After that, we present results of an active group of fourteen youth and analyze why they were more engaged than others were. We describe four cases from this group to further explore this question. Our discussion summarizes youths&iacute; status of participation as a whole, factors that have affected youths&iacute; engagement, and what we should do to ensure a good startup for the second round of the project.

Teaching Object-Oriented Systems Analysis to Non-IT Students: A Practical Experience
Authors: Nor Iadah Yusop
Venue: Proceedings of the Sixth International Conference on Quality Software (2006)

Teaching software development course is not easy even to people with computer science qualification, let alone to those without such background. However, the author personal experience has proven that this is not impossible. This paper aims at sharing the method adopted in teaching object-oriented systems analysis to postgraduate students without academic qualification or experience in information technology or computer science. Most of them are merely end-users to a number of ubiquitous applications software such as word processors. For the said course, three aspects were given special emphasis: concepts and theories familiarization, application of the theories, and familiarization of technical contents. In view of their background, with respect to the aspects addressed, the author would suggest that the method applied in the teaching of systems analysis is considerably successful for they manage to produce the deliverables required with acceptable quality.
Combining Feature-Oriented Analysis and Aspect-Oriented Programming for Product Line Asset Development
Authors: Kwanwoo Lee, Kyo C. Kang, Minseong Kim, Sooyong Park
Venue: Proceedings of the 10th International on Software Product Line Conference (2006)

Feature-oriented analysis (FOA) provides key information for developing reusable and adaptable product line assets. The information includes commonalities and variabilities, various dependencies between features, and their binding time information. On the other hand, aspect-oriented programming (AOP) provides effective mechanisms for encapsulating crosscutting concerns into separate entities, called aspects. By tightly coupling FOA with AOP, we can enhance reusability, adaptability, and configurability of product line assets. In this paper, we present detailed guidelines on how FOA and AOP can be combined. To validate our approach, we applied it to the engineering of an intelligent service robot product line.
Blind identification of under-determined mixtures based on the characteristic function
Authors: Pierre Comon, Myriam Rajih
Venue: Signal Processing (2006)

Linear mixtures of independent random variables (the so-called sources) are sometimes referred to as under-determined mixtures (UDM) when the number of sources exceeds the dimension of the observation space. The algorithms proposed are able to identify algebraically a UDM using the second characteristic function (c.f.) of the observations, without any need of sparsity assumption on sources. In fact, by taking higher order derivatives of the multivariate c.f. core equation, the blind identification problem is shown to reduce to a tensor decomposition. With only two sensors, the first algorithm only needs a SVD. With a larger number of sensors, the second algorithm executes an alternating least squares (ALS) algorithm. The joint use of statistics of different orders is possible, and a LS solution can be computed. Identifiability conditions are stated in each of the two cases. Computer simulations eventually demonstrate performances in the absence of sparsity, and emphasize the interest in using jointly derivatives of different orders.

Venue: Proceedings of the 8th conference on Human-computer interaction with mobile devices and services (2006)

As the number of public displays in the environment increases, new opportunities open up to improve situated interaction and to enable new kinds of applications. In order to make distributed display resources available to nomadic users, a key issue to address is how control can be dynamically shared between display users. It is important to study how control over a shared display can be acquired, released or shared by nomadic and residential users given their competing demands for display resources.In this paper, we present a system and a user study investigating these issues in the context of two applications both competing for display resources provided by a deployment of interactive office doorplates. The first application (Hermes II) provides situated note leaving and messaging services whereas the second one (GAUDI) supports user navigating a university department. Office occupants (i.,e. residential users) can control whether the navigation application may (temporarily) use their doorplate display (thus giving priority to the navigation needs of nomadic users to the department). We report on findings from a user study, and discuss interface design implications for specifying display control.
Edits - Data Cleansing at the Data Entry to assert semantic Consistency of metric Data
Authors: Hans-J. Lenz, Veit Koppen, Roland M. Muller
Venue: Proceedings of the 18th International Conference on Scientific and Statistical Database Management (2006)

It is a matter of fact that the input of numeric data into databases needs careful screening to avoid semantic incoherency with respect to the knowledge at hand. In nearly all real applications such knowledge exists as models, i.e. as balance equations, behavioral equations or simply as definitions. The representation of those objects is possible by validation rules ("edits"), which are roughly speaking specially tailored tests. The methodology is presented, recent work in progress is shown, and a business application is presented.
Prediction-Table Based Fault-Tolerant Real-Time Scheduling Algorithm
Authors: Dong Liu, Chunyuan Zhang, Rui Li
Venue: Proceedings of the Seventh International Conference on Parallel and Distributed Computing, Applications and Technologies (2006)

In order to predict accurately whether primary versions of real-time tasks is executable in software fault-tolerant module, a new algorithm, PTBA, Prediction-Table Based Algorithm, is presented. PTBA uses prediction-table to predict whether a host primary can meet its pre-deadline. Prediction-table contains the pre-assignment information of tasks between the current time and the alternates' notification time. If the prediction result shows that host primary has not enough time to execute, it will be aborted. Otherwise, prediction-table is referenced to schedule tasks with low overhead. The novelty of PTBA is that it schedules primaries according to their corresponding alternates' notification time and has no extra scheduling overhead in prediction-table mode. Simulation results show that PTBA allows more execution time for primaries and wastes less processor time than the well-known similar algorithms. PTBA is appropriate to the situation where the periods of tasks are short and software fault probability is low.
Measurement of frequency responses of nonlinearly distorted SISO systems in noisy environments with generalized parameter frequency response estimators
Authors: Alexander Potchinkov
Venue: Signal Processing (2006)

Topic of this paper is the measurement of frequency responses of SISO systems in the presence of nonlinear system distortions and measurement noise. The measurement uses periodic test signals and digital signal processing. Nonlinear distortion contributions and noise will be modelled by two noise sources which are located at system input and at system output. The justification of modelling the deterministic distortion contributions as (random) noise is given in the appendix. The criteria of test signal design will be discussed and appropriate test signals will be proposed. The known frequency response estimators H1, H>2, Hr (H3) and Hv are motivated, compared and the systematic estimation errors are computed. In addition, generalized parameter frequency response estimators are proposed. A way of deriving generalized parameter frequency response estimators will be introduced in this paper. This way offers particular transparency. The generalized estimators include the known estimators are special cases and they can be adapted to the distortion characteristics which makes these estimators to candidates for the desired universal estimators.
Extracting Personal Conceptual Structures from PC Documents and its Application to Web Search Personalization
Authors: Hiroaki Ohshima, Satoshi Oyama, Katsumi Tanaka
Venue: Proceedings of the 21st International Conference on Data Engineering Workshops (2005)

This paper proposes a method of extracting personal conceptual structures from documents on a personal computer that contain a great deal of personal information, and applying them to personalize Web searches. Everybody has differing ideologies, concepts, and knowledge and there is a lot of personal information stored on PCs. While it is easy for a person to determine what a PC user thinks and knows, computers cannot. In this work, two types of personal conceptual structures are represented, i.e., a "personal concept tree" and "relationships between terms". The "personal concept tree" indicates personal concept classification. Relationships between terms" indicates how the user thinks of a term, and how it is created from the "personal concept tree" based on deviations in the appearance of the term. This paper also proposes the personalization of Web searches, i.e., expanding query keywords and re-ranking of search results using personal conceptual structures.
