Putting the pieces together: Online argumentation vee diagrams enhance thinking during discussions

We examine the effect of online Argumentation Vee Diagrams (AVDs) on the quality of students’ argumentation during asynchronous, online discussions. With AVDs, students develop arguments on both sides of a controversial issue and then develop an integrated, overall final conclusion. In this study, students used AVDs individually before composing discussion notes, and then—at the end of the discussion—jointly created a group AVD using Wiki technology. Compared to a control group, the experimental intervention was found to significantly enhance the integration of arguments and counterarguments (specifically, compromises) and fostered opinion change. For AVDs to be effective, however, it was found to be necessary to include specific scaffolds on how to evaluate argument strength and/or to provide practice and feedback in using the AVDs.     

Intellectual property protection for deep semantic segmentation models

Deep neural networks have achieved great success in varieties of artificial intelligent fields. Since training a good deep model is often challenging and costly, such deep models are of great value and even the key commercial intellectual properties. Recently, deep model intellectual property protection has drawn great attention from both academia and industry, and numerous works have been proposed. However, most of them focus on the classification task. In this paper, we present the first attempt at protecting deep semantic segmentation models from potential infringements. In details, we design a new hybrid intellectual property protection framework by combining the trigger-set based and passport based watermarking simultaneously. Within it, the trigger-set based watermarking mechanism aims to force the network output copyright watermarks for a pre-defined trigger image set, which enables black-box remote ownership verification. And the passport based watermarking mechanism is to eliminate the ambiguity attack risk of trigger-set based watermarking by adding an extra passport layer into the target model. Through extensive experiments, the proposed framework not only demonstrates its effectiveness upon existing segmentation models, but also shows strong robustness to different attack techniques.     

Intellectual property protection: everything you've always wantedto know

This article examines the legal issues affecting people who spend a lot of time in the computer hardware/software arena. It discusses some of the basic patent-application disclosure requirements which inventors must satisfy. These requirements enumerate what inventors must include in the patent application to meet the US Patent Office's definition of a “fully described” invention. To more clearly demonstrate some of the prominent issues I discuss examples from a patent attorney with both a professional and personal interest in the acquisition of intellectual property rights for computer-related inventions     

Putting it all together – Formal verification of the VAMP

In the verified architecture microprocessor (VAMP) project we have designed, functionally verified, and synthesized a processor with full DLX instruction set, delayed branch, Tomasulo scheduler, maskable nested precise interrupts, pipelined fully IEEE compatible dual precision floating point unit with variable latency, and separate instruction and data caches. The verification has been carried out in the theorem proving system PVS. The processor has been implemented on a Xilinx FPGA. A shorter version of this article with the title “Instantiating uninterpreted functional units and memory system: functional verification of the VAMP” appeared in [8]. The work reported here was done while all the authors were with Saarland University.

Design of reconfigurable array processor for multimedia application

With the rapid growth of the amount of computations and power consumption, there is a pressing need for a high power-efficiency architecture, which takes account of computational efficiency and flexibility of application. This paper proposes a type of array-processor architecture for multimedia application which is programmable and self-reconfigurable and consists of 1024 thin-core processing elements (PE). The performance and power dissipation are demonstrated with different multimedia application algorithms such as hash, and fractional motion estimation (FME). The results show that the proposed architecture can provide high performance with less energy consumption using parallel computation.

     

APADYT: a multimedia application for SEN learners

Information technologies have been increasingly used in education in recent years, mainly due to their possibilities of improving the classroom experience, especially those related to multimedia facilities. The new technologies are especially useful for the Special Educational Needs (SEN) group. In this paper we introduce APADYT Professional (Aplicación Psicopedagógica para Apoyo en Diagnóstico Y Tratamiento—Psychopedagogical APplicAtion for supporting Diagnosis & Education), an application developed in collaboration with SEN teachers, children with SEN and parents. This multimedia application supports SEN treatment and it exploits multi-touch interfaces to offer SEN learners multimedia learning activities. The main advantage of APADYT Professional is that it helps teachers’ work by providing them with a single application that supports multiple tasks. In this way APADYT fills the gap in the existing applications, by supporting pupil management, computer-assisted learning process, report generation, planning, communication between parents and specialists, authoring tools and others interesting facilities in an integrated way. User-centered techniques have been successfully used for the development of APADYT, as the results of the User eXperience (UX) assessment reported in this paper shows, These results also shows that the approach followed to design this multimedia application is extremely appreciated by SEN teachers and specialists.

Putting Our Headers together: A Report on the TEI Header Meeting 12 September 1997

The TEI Header plays a vital role in the documentation and interchange of TEI conformant electronic texts. Moreover, this role is becoming increasingly important as more people follow the recommendations set out in TEI P3, and libraries, archives, and electronic text centres seek to share their holdings of electronic texts. However, the fact that TEI P3 allows for flexibility in the structure and content of TEI Headers has meant that divergent practices have begun to emerge within the numerous projects and initiatives creating TEI texts. With this in mind, the Oxford Text Archive hosted a one-day colloquium of leading TEI exponents, at which invited participants were encouraged to share their views and expertise on creating TEI Headers, and work together to develop some recommendations towards good practice.

An object-oriented multimedia database system for a news-on-demand application

We describe the design of a multimedia database management system for a distributed news-on-demand multimedia information system. News-on-demand is an application that uses broadband network services to deliver news articles to subscribers in the form of multimedia documents. Different news providers insert articles into the database, which are then accessed by users remotely, over a broadband, asynchronous transfer-mode (ATM) network. The particulars of our design are an object-oriented approach and strict adherence to international standards, in particular the Standard Generalized Mark-up Language (SGML) and Hy-Time. The multimedia database system has a visual query facility, which is also described in this paper. The visual query interface provides three major facilities for end users: presentation, navigation, and querying of multimedia news documents. The main focus, however, is the querying of multimedia objects stored in the database.

Semi-supervised adaptive feature analysis and its application for multimedia understanding

Multimedia understanding for high dimensional data is still a challenging work, due to redundant features, noises and insufficient label information it contains. Graph-based semi-supervised feature learning is an effective approach to address this problem. Nevertheless, Existing graph-based semi-supervised methods usually depend on the pre-constructed Laplacian matrix but rarely modify it in the subsequent classification tasks. In this paper, an adaptive local manifold learning based semi-supervised feature selection is proposed. Compared to the state-of-the-art, the proposed algorithm has two advantages: 1) Adaptive local manifold learning and feature selection are integrated jointly into a single framework, where both the labeled and unlabeled data are utilized. Besides, the correlations between different components are also considered. 2) A group sparsity constraint, i.e. l _2?,?1-norm, is imposed to select the most relevant features. We also apply the proposed algorithm to serval kinds of multimedia understanding applications. Experimental results demonstrate the effectiveness of the proposed algorithm.

Intellectual property rights in computer software: Issues at stake for developing countries

Abstract

Intellectual Property Rights (IPR) have become important in the discourse amongst nations as it may have substantial bearing on the wealth of nations in the future. Computer software is an important component of these new types of property. Since developing countries have some of the factors of production in software and certain developing countries have made significant investments in education, it has become critical to study the impact of IPR on developing countries. In this paper, we investigate IPR in computer software and their implications for developing countries (sometimes with specific reference to India), especially in the context of the GATT/TRIPs agreement that was recently concluded at Marrakesh.
