Abstract: Research has shown that motorcycle riders persona and posture have a large impact on motorcycle safety, bringing these challenges into the domain of human factors. Besides these aspects, motorcycle designers have to consider the emotional values of such artefacts for it to be successful in the market. Indeed, motorcycle designers have to take into account multitude of factors when developing such artefacts. These all pose challenges to designers whilst carrying out motorcycle design. A study was carried out with motorcycle designers to investigate their current design practices, and challenges faced during motorcycle design. A critical literature review revealed that there is a research gap in decision consequence models which do not take a holistic view of the underlying phenomena during design decision-making of motorcycle designers. The gap in literature together with the outcome of the study, collectively led to the development of a decision consequence-based phenomena model during motorcycle design. The model is validated with two case studies from the motorcycle industry through the use of a comparative-validation approach.

DISINFECTANT CHAMBER FOR KILLING BODY GERMS WITH INTEGRATED FAR-UVC CHAMBER (FOR COVID-19)
by Sangam Sahu, Shivam Krishna Pandey, Atul Mishra
Abstract: A human body can be infected by over 200 viruses existing in the world. A share of these viruses would just stick to the human body (for exterior) but not infect it per se. We propose a disinfecting chamber / Magnetic body scanner, used to screen persons entering a security-controlled area for the presence of security threats hidden under the clothing such as guns, knives, explosives and contrabands. Just like the body scanner, an innovative scanner system is required to disinfect and sanitize the body from life threatening viruses such as the SARS-Cov 19 (Corona Virus). The scanner chamber has five sections, namely, the entrance, thermal image scanner, FAR-UVC chamber, disinfectant spray chamber, and the exit section. The integrated thermal image scanning section can detect the body temperature with the help of a thermal image shown on the computer screen. The FAR-UVC chamber is used to extract the virus-killing property of FAR-UVC rays proven to have negligible damage on the human skin. The disinfectant chamber is where the human body is sprayed with a disinfectant after which he or she is allowed to exit the chamber.
Keywords: FARUVC; disinfectant spray; sanitization chamber.
Coherence of Interior and Exterior Formal Qualities in Parametrically Designed Buildings
by Morteza Hazbei, Carmela Cucuzzella
Abstract: Parametrically designed buildings often have spectacular exterior forms, quasi-sculptural, that catch the eye of the passers-by. However, the indoor space design of parametric architecture has received less attention due to over emphasis on exterior aesthetic requirements. This may lead to superficial aesthetics where the quality of the indoor space is not compatible with the outer building envelope. This paper seeks to highlight the importance of coherency between these two parts of parametrically designed buildings. To do this, we conducted a two-step survey with architecture students where we first presented a set of different views of indoor and outdoor spaces of some parametric buildings. They were asked to match the images of the interior spaces to images of the exterior facades. In the second step, students were asked to evaluate each building by their formal criteria (specifically the coherence of the fa

Emotional characterization of chairs by descriptors, neural network and verbalized analysis
by Cyril Bertheaux, Rosario Toscano, Roland Fortunier, Nicolas Poisson, Jean-Christophe Roux, Céline Borg
Abstract: In this paper, the emotional value of chairs is evaluated from a sample covering more than a century of design (1900-2014). The purpose of this research is to study the emotional responses to the visual perception of chairs. Emotional reactions are studied according to two protocols. The first protocol classically accesses the emotional valence and arousal of the chairs, whereas the second consists of validating emotional descriptors as key factors for the evaluation of the valence. These emotional descriptors appears to be very important for the designer, particularly when the shopping is online. The product space is first created, by selecting 70 chairs from the collection of the Museum of Modern and Contemporary Art in Saint-Etienne. According to the first protocol, it is tested with a Circumplex model, which collects valence and arousal from a panel of 65 individuals. Then, 18 chairs are selected out of this product space: the most unpleasant, the most pleasant, and the most neutral ones. According to the second protocol, 6 emotional descriptors are proposed: originality, comfort, beauty, confidence, balance of proportions and stability. The evaluation of these descriptors is collected, together with the valence of the chairs, on a new panel of 26 participants. Using a mathematical model based on neural network, an "estimated valence" is then derived from the evaluation of these emotional descriptors. This estimated valence is finally compared with the verbalized valence. The results show that there is a good correlation between the verbalized and the estimated valences. The emotional descriptors proposed are thus validated and can be used as key factors for designing chairs.
Keywords: chair; emotional design; descriptive evaluation; neural network.
INVESTIGATION OF ATTAPULGITE CLAY CRUSHING BY BIONIC TOOTH PLATES INSPIRED FROM CONVEX STRUCTURES ON BODY SURFACE OF DUNG BEETLES
by Xingqiao Deng, Shike Wang, Jie Wang, Shisong Wang, Yucheng Liu, Ge He
Abstract: A bioinspired tooth plate structures imitating convex structures on the head and body surfaces of dung beetles was presented and analyzed using the Discrete Element Method (DEM) through the EDEM software. Simulation results showed that compared with the regular tooth plates without bionic structures, the bionic crushing tooth plate offers a better performance and higher efficiency in crushing the wet attapulgite clay. Based on the simulation results, a two-stage crushing machine was designed, produced, and validated through experiments. This crusher consists of a sawtooth double-geared roller crusher at the top to process the course materials and a double-geared roller crusher that involves the bionic convex structures on its tooth plate surface to continue to break the clay with manageable sizes into final fine clay particles. Experimental results confirmed that the developed crushing equipment with the bioinspired convex structures implemented can effectively crush the attapulgite clay with high moisture content, which cannot be crushed by existing crushers due to the adhesion of the wet clay particles to the solid surface of the tooth plates. The produced crushing equipment has been applied for processing the attapulgite clay in Xuyi, China, and the design idea can be extensively applied to develop other equipment for crushing more rare earth minerals with high moisture content. DEM models for the clay particles were created based on Hertz-Mindlin bonded contact theory and the material properties of the attapulgite clay were obtained from a series of material tests conducted by the authors.
Keywords: Attapulgite clay; crushing performance; bionic design; dung beetle; two-layered double geared-roller crusher.
Special Issue on: ICESF 2019 Energy and Sustainable Futures
by Christopher Pegg, Yatin Suri, Sheikh Islam, Abhishek Asthana, Mamdud Hossain
Abstract: Power kites provide the potential rewards of obtaining the disused energy supply from high altitude wind. This paper aims to provide a design of power kites and optimise the potential for renewable power generation. The power kite was modelled using Computational Fluid Dynamics to study its characteristics. The numerical modelling results were compared against the wind tunnel experimental study involving two 3D printed power kites. The design was optimised using several variables including aerofoil choice, surface roughness, wind speed and operating parameters. The results suggest that operating the kites at minimum 15 m horizontal separation is favourable, with the trailing kite operating below the leading kite, thus removing the potential for it to operate in the wake turbulence of the latter. This paper presents relevant, applicable data which can be used for predicting the performance, and potentially optimising future power kite design.

An overview of applications of renewable energy methods in the development of Structural Health Monitoring systems
by Faisal Siddiqui, Paul Sargent, Nashwan Dawood, Sergio Rodriguez
Abstract: Structural health monitoring is an efficient method for monitoring and scheduling maintenance of civil engineering infrastructure when exposed to various types of loadings. Advances in innovative technologies such as low power wireless sensor networks have further improved the efficiency and versatility of SHM systems. Moreover, harvesting energy from ambient and renewable energy sources, such as solar, wind, structural thermal gradient and vibration, have addressed the issue of the limited life span of batteries powering these sensors. Over the years, the scope of different harvesting mechanisms has been extended from a sensors' power source to sensing structural anomalies. This paper reviews the scope of different energy harvesting technologies in improving the robustness and efficiency of a structural health monitoring system.

Using ratio-weighted sums to project data into future scenarios: the case study of heating systems
by Miquel Banchs-Piqué, David J. Hutchinson, Victor M. Becerra, Mark R. Gaterell
Abstract: Carefully planning the future of the building sector is key to mitigate greenhouse gas (GHG) emissions. The largest contributor of the building sector to GHG emissions is the energy used for space and water heating. Therefore, information on its possible future evolutions can be very valuable. Future scenarios can be used to investigate the behaviour of existing data into the future. Here, electricity demand data are projected into four distinct futures of the household's use of electric heating systems. These projections offer, however, only partial information about the possible evolutions of the residential energy demand, as they account only for changes in the type of heating systems used. This information could, together with a range of other projections, be used to improve the planning of the future residential sector.

Assessment of an innovative floating hydro generator prototype through experiments and modelling
by Abhishek Asthana, Sanjay Mukherjee
Abstract: This work involves developing and testing a prototype of new design of a floating undershot waterwheel. The design uses linkage mechanism between paddles and shaft to always keep the paddles normal to the water-flow to maximise power transmission and efficiency, and to allow using the waterwheel in very low water flow conditions. The prototype was tested in two different field trials: (i) in a swimming pool with jets of water to replicate low flow conditions and (ii) in a millstream to replicate normal flow conditions to experimentally measure the mechanical power outputs. The experiments showed 55-69% efficiency, close to the best performances for undershot water wheels recorded in literature. The floating design also allows aquatics to move freely under the wheel and does not require disruptive construction of barrages or other permanent structures. The findings are promising and encourage further optimisation of the current design and target even higher efficiencies.
Keywords: Hydropower; water wheels; renewable energy; Computational Fluid Dynamics (CFD).
