Using CA to Find Out How a Child with High Functioning Autism Responds to Questions in Different Settings

Anecdotal reports on the discourse of children with High Functioning Autism (HFA) often claim that failure to respond to questions is a key characteristic. However, Kremer-Sadlik (2004) found that HFA children respond 85% of the time to questions, and that 75% of the time their responses are also communicatively “adequate,” meaning that they address the pragmatic intent behind the question as well as its surface form. Using Conversation Analysis (CA) as one of her methodologies, Kremer-Sadlik explained this surprisingly high number by showing that in her data, which consisted of audio/videotaped family interactions, family members extensively scaffolded the children’s responses, teaching and coaching them in appropriate response patterns with every interaction. Thus, in Kremer-Sadlik’s study, CA complements quantitative methods in describing language and interaction patterns of impaired individuals that run counter to popular belief. These results prompted me to ask whether response behavior of HFA children would be similar in non-family settings

Indoor Characterisation of a Photovoltaic/ Thermal Phase Change Material System

Photovoltaic/ thermal (PV/T) systems integrate photovoltaic and solar thermal technologies and have the added advantage of producing both electrical and thermal energy simultaneously. This study has been carried out to investigate the performance of a PV/T phase change material (PCM) system under experimental climatic conditions. Electricity is generated by the PV during daylight hours and the heat produced is absorbed and stored in PCM. Water flows through a pipe network within the PCM and absorbs the stored heat in the PCM. In the PV/T-PCM system, water remained at a higher temperature for an extended period of time as well as shifting the time period of available heat when compared to the reference systems

No Longer Trending on Artstation: Prompt Analysis of Generative AI Art

Image generation using generative AI is rapidly becoming a major new source of visual media, with billions of AI generated images created using diffusion models such as Stable Diffusion and Midjourney over the last few years. In this paper we collect and analyse over 3 million prompts and the images they generate. Using natural language processing, topic analysis and visualisation methods we aim to understand collectively how people are using text prompts, the impact of these systems on artists, and more broadly on the visual cultures they promote. Our study shows that prompting focuses largely on surface aesthetics, reinforcing cultural norms, popular conventional representations and imagery. We also find that many users focus on popular topics (such as making colouring books, fantasy art, or Christmas cards), suggesting that the dominant use for the systems analysed is recreational rather than artistic.Comment: Paper accepted for EvoMUSART 2024, Aberystwyth, Wales, United Kingdom, 3-5 April 202

On Surface Currents in a Polycrystalline Solar Cell Acting as Ground Plane for Microstrip Patch Antennas

The integration of communication devices with photovoltaic (PV) technology leads to the development of autonomous communication systems distinguished by immunity to grid breakdowns and eco-friendliness

Transparent Patch Antenna on a-Si Thin Film Glass Solar Module

An optically transparent microstrip patch mounted on the surface of a commercially available solar module is proposed. The patch comprises a thin sheet of clear polyester with a conductive coating. The amorphous silicon solar cells in the module are used as both photovoltaic generator and antenna ground plane. The proposed structure provides a peak gain of 3.96 dBi in the 3.4-3.8 GHz range without significantly compromising the light transmission in the module. A comparison between copper and transparent conductors is made in terms of antenna and solar performance. The proposed technique is considerably simpler that previous integration approaches

Novel Techniques for the Integration of Antennas and Photovoltaic Cells

Various novel approaches to the integration of antenna and photovoltaic technologies are proposed. These include the use of polycrystalline solar cells as groundplane for microstrip patch antennas as well as for reflectors of half-wave dipole antennas. Transparent materials were also evaluated as antenna radiating elements, allowing greater solar efficiency. A novel technique illustrating how emitter-wrap-through rear contact solar cells can be used as a folded-dipole antenna, which is located in the focal line of a parabolic solar concentrator, to provide high solar efficiency as well as high antenna gain, is presented

Influence of Solar Heating on the Performance of Integrated Solar Cell Microstrip Patch Antennas

The integration of microstrip patch antennas with photovoltaics has been proposed for applications in autonomous wireless communication systems located on building façades. Full integration was achieved using polycrystalline silicon solar cells as both antenna ground plane and direct current power generation in the same device. An overview of the proposed photovoltaic antenna designs is provided and the variation characterised of the electromagnetic properties of the device with temperature and solar radiation. Measurements for both copper and solar antennas are reported on three different commercial laminates with contrasting values for thermal coefficient of the dielectric constant

Design Considerations for Real-Time Collaboration with Creative Artificial Intelligence

Machines incorporating techniques from artificial intelligence and machine learning can work with human users on a moment-to-moment, real-time basis to generate creative outcomes, performances and artefacts. We define such systems collaborative, creative AI systems, and in this article, consider the theoretical and practical considerations needed for their design so as to support improvisation, performance and co-creation through real-time, sustained, moment-to-moment interaction. We begin by providing an overview of creative AI systems, examining strengths, opportunities and criticisms in order to draw out the key considerations when designing AI for human creative collaboration. We argue that the artistic goals and creative process should be first and foremost in any design. We then draw from a range of research that looks at human collaboration and teamwork, to examine features that support trust, cooperation, shared awareness and a shared information space. We highlight the importance of understanding the scope and perception of two-way communication between human and machine agents in order to support reflection on conflict, error, evaluation and flow. We conclude with a summary of the range of design challenges for building such systems in provoking, challenging and enhancing human creative activity through their creative agency
