The Fusion Matching Method for Polyphonic Music Feature Database

Abstract: This article proposes the fusion matching method for polyphonic music feature database which are extracted from music signal. The best way looking for the song is the tag based retrieval method using metadata like title, singer, lyrics, etc. This is very convenient and powerful way if you have already known about information of contents what you are looking for. But if you do not have any information of the contents, contents based query method might be a plan-B. Query by Singing/Humming (QbSH) is the powerful tool and the best supplemental method looking for song or music over the internet or among huge database. This topic has been researched for a so long time with various solutions. But, there have not been any outstanding solution so far. So we propose the fusion matching method with three matchers against polyphonic music signal in order to improve matching performance. Proposed method is based on Dynamic Time Warp (DTW), Linear Scaling (LS) and Quantized Binary Code (QBcode) and then combines them with fusion score based PRODUCT rule.

AI Management Platform with Embedded Edge Cluster

Abstract: The area of AI application continues to grow from resource-rich environment such as cloud to resource-constraint environment such as embedded devices. However, management of AI on the embedded device is still a challenging task due to different environment other that resource-rich devices. This paper proposes an AI management platform for a cluster which consists of edge devices and cloud resources. The proposed system provides efficient methods to identify different hardware acceleration resources and resource management for a specific AI application. The implementation of the proposed platform on a cluster which consists of cloud VMs and embedded devices are described presented.

A computer supported learning environment to support pupils with cognitive disabilities and their teachers

Abstract: Although there is no doubt that computers are highly capable to provide pupils with cognitive disabilities in learning we observe an immense lack of professional learning software for this target group. There are few products designed by special education teachers with a high level of instructional design but at a low technical level, unflexible and not adaptable. In contrast there are loads of colorful animated commercial products, mostly designed for primary school pupil and often with absence of any instructional quality. In our project we want to overcome these problems by developing a learning platform which meets the needs of both, the pupils with cognitive disabilities and their teachers. In this interactive presentation will present an overview of this platform and give some examples of good practice as well as latest results of an ongoing study about facilitating communication between pupils with cognitive disabilities using a CSCL setting.

CSCL practices

Abstract: The CSCL 2009 international conference on the theme “CSCL Practices” will be held in Rhodes, Greece, on June 8-13, 2009. Paper submissions are due November 1 and workshop/tutorial proposals are due December 15. For conference information, see http://ISLS.org/CSCL2009. The conference focuses on issues related to formal and informal learning through collaboration, promoting productive collaborative interactions with the help of the computer and other communication technologies. The conference theme “CSCL Practices” emphasizes practices relating to technology-based collaborative learning in schools, workplaces, and daily life. The CSCL community is not only concerned with studying and designing effective tools to support CSCL practices, but also with identifying specific educational and professional practices that are associated with their appropriate usages. In order to study practices in a reflective way, powerful theories and analytical approaches are required. The aim is to understand how learning emerges: on an individual level, on a groupcognition level, and at the community level. The CSCL conference and the CSCL journal work together to advance the collective understanding of the community of researchers and practitioners. The journal organizes a symposium at each conference and publishes expanded versions of important conference presentations. We look forward to seeing you on the historic island of Rhodes.

Understanding and mitigation of scratch induced magnetic damage in perpendicular recording media

Abstract: Hard disk drives (HDDs) are among the most widely used information storage components in these digital times, since they were commercialized in late 1970s. The perpendicular magnetic recording (PMR) media using (CoCrPt) x (Metal Oxide) 1−x magnetic alloys have reached an areal density of 700GB/in2 and beyond[1]. The current researches focus on achieving higher grain refinement and increasing uniaxial magnetocrystalline anisotropy and so on [2] to improve signal-to-noise ratio. Mechanical reliability is also one of key important properties to be considered for the recording media design [3].
