    Video Conferencing Evaluation Considering Scalable Video Coding and SDN Network

    Video conferencing is very common nowadays, and it may contemplate heterogenous devices (e.g., smartphones, notebooks, game consoles) and networks in the same session. Developing video conferencing systems for this myriad of devices with different capabilities requires special attention from system designer. Scalable video coding (SVC) is a prominent option to mitigate this heterogeneity issue, but traditional Internet protocol (IP) networks may not fully benefit from such a technology. In contrast, software-defined networking (SDN) may allow better utilization of SVC and improvements on video conferencing components. This paper evaluates the performance of video conferencing systems adopting SVC, SDN and ordinary IP networks, taking into account throughput, delay and peak signal-to-noise ratio (PSNR) as the metrics of interest. The experiments are based on Mininet framework and distinct network infrastructures are also considered. Results indicate SDN with SVC may deliver better video quality with reduced delay and increased throughput

    Indoor air Quality and Its Effects on Health in Urban Houses of Indonesia: A case study of Surabaya

    There is a possibility that the sick building syndrome has already spread widely among the newly constructed apartments in major cities of Indonesia. This study investigates the current conditions of indoor air quality, focusing especially on formaldehyde and TVOC, and their effects on health among occupants in the urban houses located in the city of Surabaya. A total of 471 respondents were interviewed and 82 rooms were measured from September 2017 to January 2018. The results indicated that around 50% of the respondents in the apartments showed some degrees of chemical sensitivity risk. More than 60% of the measured formaldehyde levels in the apartments exceeded the WHO standard, 0.08 ppm. The respondents living in rooms with higher mean formaldehyde values tended to have higher multiple chemical sensitivity risk scores. KEYWORDS: Indoor air quality, Sick building syndrome, QEESI, Formaldehyde, Developing countrie

    The role of the artist at the beginning of the twenty-first century: An exploration of dialectical processes in art and science with particular reference to biologically based art

    This thesis examines the role of the artist at the beginning of the twenty-first century. It focuses on the interaction between art and science in an exploration of the dialectical processes that may occur in that interaction. Researchers have recently developed techniques in stem cell technology and genetic modification that offer remarkable potential and bring possible advantages and disadvantages for scientists and the wider community. In response to these new technologies, scientists and artists have developed collaborative projects and, in some instances, artists have moved from the studio to the science laboratory to create work called sci-art, bio-art, or moistmedia. This new inter-disciplinary activity affords prospects of dialectical processes: it crosses many boundaries and disturbs some existing conventions and practices, and, for the artists involved, the access to innovative materials has moved their work into areas of new skills and concepts. The extent to which traditional artists and those with collaborative sci-art practices contribute to the debate on important social and cultural issues forms part of this study. The research data was gathered during semi-structured interviews with scientists and artists, of whom three scientists and five artists are involved in sci-art collaborations. Proposed dialectical processes identified in the data are outlined throughout the document. A discussion about the ways in which contemporary art and artists are located within the current social and cultural environment; the status accorded visual art education today; and the manner in which commentators and other members of the public regard the elements and functions of art, forms the initial framework. This is followed by an overview of biologically based art practices, worldwide, that provides a background for a discussion of sci-art collaborations. These collaborations are initiated by a wide range of individuals and organisations and, according to the participants, the intentions of the originator or funding body have the potential to influence the outcome of the collaboration. The research explores possible conflicts of interest between the parties involved in these interactions, and any perceived implications for creative freedom. This study also examines current attitudes towards the notion of creativity in science and art, the avant-garde, and the relevance of philosophy and theory in art practices. It discusses the extent to which technology influences the creative process, and highlights issues that augment, interrogate or philosophise about the role of the contemporary artist. The research found that, although the notion of Snow’s ‘two cultures’ still has supporters, there are more similarities than dissimilarities between scientists and artists. Although some instances of Hegelian dialectical processes were identified, the data residing in many of the participants’ responses called for a more post-structuralist, non-linear approach to the dialectic as described by Jervis (1998), Janesick (2000) and others. In this way, the data drew attention to many complex issues and tensions that emanate from the interaction between art, science, technology, government and commerce, and the interaction between artists and the culture and society in which they live at the beginning of the twenty-first century

    Design revolutions: IASDR 2019 Conference Proceedings. Volume 4: Learning, Technology, Thinking

    In September 2019 Manchester School of Art at Manchester Metropolitan University was honoured to host the bi-annual conference of the International Association of Societies of Design Research (IASDR) under the unifying theme of DESIGN REVOLUTIONS. This was the first time the conference had been held in the UK. Through key research themes across nine conference tracks – Change, Learning, Living, Making, People, Technology, Thinking, Value and Voices – the conference opened up compelling, meaningful and radical dialogue of the role of design in addressing societal and organisational challenges. This Volume 4 includes papers from Learning, Technology and Thinking tracks of the conference
