Biophilic Design Applications: Putting Theory and Patterns into Built Environment Practice
Authors: Downton Paul , Jones David , Zeunert Josh , Roös Phillip
Published: February 2017

In 1984 E.O. Wilson (1984) introduced and popularized the Biophilia hypothesis defining biophilia as "the urge to affiliate with other forms of life" (Kellert & Wilson 1995: 416).  Wilson’s biophilia hypothesis suggests that there is an instinctivebond between human beings and other living systems.  More recently, in the USA, Browning et al (2014) have proposed ‘14 Patterns of Biophilic Design’ within a framework for linking the human biological sciences and nature to built environment design offering a series of tools for enriching design opportunities, and avenues for design applications as a way to effectively enhance the health and well-being of individuals and society.  While biophilia is the theory, biophilic design as advocated by Kellert et al (2008) and Beatley (2010) internationally offers a sustainable design strategy that seeks to reconnect people with the ‘natural environment’.  Overall, from what little research has been undertaken internationally in the last 10 years, there is a solid understanding as to the applied application of this theory, its principles and processes to built environment design and no research about to how to retrofit the existing urban fabric using this approach.  This paper reviews the application of biophilic design in Australia, including the scope of design, health and wellbeing literature, the ‘14 Patterns of Biophilic Design’ and performative measures now unfolding, brings forward a new Biophilic Design Pattern, and considers the value the approach offers to built environment practice as well as to human and non-human occupants.
Building a case for an International Design Centre in Geelong
Authors: Kelly Meghan , Kennedy Russell
Published: February 2017

Geelong has a long history of design innovation and there exists an opportunity to applaud the achievements of a city and its people whom have been punching well above their weight. The significance of these hidden achievements is currently lost in a city where deindustrialization has changed the landscape forever. This article proposes it is time to affirm Geelong’s role in innovative design, albeit through broad association, and offers ways to celebrate these achievements. It concludes there is an opportunity for a recognized International Design Centre based in Geelong where the past can be showcased but, more importantly, we can open the discussion for future innovation connecting industry and manufacturing with design, creating new opportunities for Geelong.
Shape optimisation of a snowboard binding highback. A case study of generative design process comparison
Authors: Leen Robert
Published: February 2017

FEA software is traditionally expensive to purchase, takes a high level of technical skill and understanding and requires users to dedicate years to develop specialist skills. With the increasing popularity of more user-friendly, elementary software packages such as Fusion360, more cost effective and efficient processes can be developed and harnessed, especially by SME’s and designers that don’t have the ability to purchase expensive software packages. One particular FEA element that has recently begun transitioning from highly specialised to more readily available is ‘generative design’ and ‘shape optimisation.' Shape optimisation has only been able to be utilised by large corporations with large research and development budgets. This case study looks at exploring and optimising the methods involved in generative design for product development and it’s aimed at facilitating practises for small to medium enterprises (SME’s).

The work described in this paper presents a study using a snowboard binding highback component which was reverse engineered using 3D scanning. A blank model, free of any discerning features was created from the scan and then used as the platform for the generative design phase. This process was completed using easily accessible software (Fusion 360) as well as high-end professional software (Ansys 16). A comparison between the two workflows analyses the resultant model outcomes and outlines efficiencies regarding processing time, technical skill, and latent difficulties of the entry-level process for generative design of the snowboarding high back.

This paper aims to demonstrate and describe an optimisation model for generative design and shape optimisation during entry-level product development.
Critical Buckling Load for Lattice Column Elements with Variable Dimensions
Authors: Alghamdi Ahmad , Leary Martin , Qian Ma , Xu Wei , Brandt Milan
Published: February 2017

Lattice structures are used in a variety of high-value engineering applications; for example, in automobile, aerospace and biomedical applications, due to their light weight, high specific strength, stiffness, heat transfer control and energy absorption. Additive Manufacturing (AM) technologies, such as Selective Laser Melting (SLM), offer radical net-shape manufacturing solutions for metallic structures directly from digital data. The prediction of AM lattice structure mechanical properties prior to manufacture is both cost and time-consuming; particularly as existing models do not readily accommodate the effects of manufacturing defects and lattice node geometry on column buckling. The critical buckling load of columns was algebraically and numerically simulated for a full Design of Experiments (DOE) of independent variables, including column length, column radius, node radius and material type. This simulation data quantifies the effect of independent variables on critical buckling load and demonstrates the limitations of algebraically prediction. This research can be extended to allow the simulation of the load carrying capacity of entire lattice structures; and to accommodate the effect of manufacturing variation on the associated load carrying capacity of AM lattice structures.

Authors: Kuppu Rao Guruprasad , Shah Tanmay , Dayanand Shetty Vijay , Ravi B.
Published: February 2017

Management of bone and joint injuries is commonly done by immobilisation using plaster/fibreglass casts. This study describes design and fabrication of patient specific cast using 3D printing.  The 3D printed cast while being patient friendly is superior to earlier casts in healing efficacy and hence redefines the joint immobilisation practice. We present here a case of “walk on brace” design and fabrication using 3D printing. The custom design of ankle immobilisation cast was done for an 18-year-old boy having tibia bone fracture during gymnastic activity. The workflow comprises of anatomical data acquisition, CAD, 3D printing, post processing and clinical approval for use. Additional features such as straps, anti-slip inner surface and tread for floor grip were incorporated in the design. 
Customised design of a patient specific 3D printed whole mandible implant
Authors: Mohammed Mazher I. , P. Fitzpatrick Angus , Gibson Ian
Published: February 2017

In this study we investigate the design methodology for the creation of a patient specific, whole mandible implant based on a patient’s medical imaging data. We tailor the implant as a treatment option for a patient who will undergo a mandibulectomy due to cancer infiltration of the jaw. We create a 3D representative model of the patient’s skeletal structure from CT scan data, and us this to generate the implant from the patient’s corrupt mandible. In this particular case study the cancer is restricted to the right region of the mandible, and so the left side is used in a symmetry matching approach to create the final model for manufacturing. The final design was 3D printed in medical grade titanium and finished using a mechanical polishing technique, the yield a near mirror finish. We found the final implant to be highly robust, and an excellent fit to a representative model of the patient’s skeletal anatomy. We believe this approach to hold considerable potential for implementation as a treatment option for mandibular complications. 
Design and fabrication considerations for three dimensional scaffold structures
Authors: Iqbal Mohammed Mazher
Published: February 2017

Porous three dimensional structures have seen extensive investigation among design engineers for a wide range of novel applications. The fabrication of such designs would not be possible using traditional manufacturing approaches owing to the dimensional intricacy of such structures, but have now become a distinct possibility owing to the maturity of 3D printing technologies. In this study, we have examined the creation of novel unit cells from mathematic surface renderings as a basis for creating tailored porous structures, before realising the final designs through Fuse Deposition Modelling (FDM) 3D printing. We examined the use of Gyroid and Schwarz primitive (P) surfaces to create novel unit cells not typically found in design software libraries. We then transpose these structures into several test geometries comprising a cylinder, cuboid and tetrahedron, which will adequately test limits of design and fabrication in regular and irregularly shaped structures. It was found that the porosities of the resulting models could be adjusted through discrete dimensional changes in the unit cell and digital wrapping procedures. It was also found that models could be fabricated using FDM printing to a minimum pore diameter of approximately 1mm with a high degree of accuracy and repeatability. Ultimately this work will provide guidance to engineering's when creating porous structures and could find usefulness in applications where optimal material usage versus porosity are required, such as in high throughput 3D fluidic applications, such as heat exchangers and tissue engineered structures.
Design of 3D knitted structures for impact absorption in sportswear
Authors: Nayak Rajkishore , Kanesalingam Sinnappoo , Vijayan Arun , Wang Lijing , Padhye Rajiv , Arnold Lyndon
Published: February 2017

Some sports involve frequent collisions between the players, and between a player and the playing surface, leading to injuries such as muscular strains, dislocations, sprains, lacerations, fractures and soft tissue injuries. In several instances, these injuries are so severe that they may cause bone fracture or dislocation of joints. In recent years, researchers are focusing on reducing these injuries by using protective gears and protective clothing to cover the torso, head, hands and legs. For rugby uniforms, shoulder pads are integrated to reduce the incidence of shoulder injury during the making or receiving of front-on tackles. Although some shoulder pads such as closed cell foams are commercially available, they are often discarded by the players due to their stiffness and discomfort. Hence, in this research an attempt was made to explore the potential of using flexible textile structures to replace the currently used commercial foam. Three flexible textile structures (A, B and C) were designed in three dimensional (3D) structure using Shima Seiki flatbed machine. Each fabric consisted of 3 layers, 2 external (face and back) and one internal layer. Fabric A consisted of mercerized cotton (space dyed) and Elastane external layers, whereas ballistic nylon internal layer. Fabrics B and C were prepared using Dyneema (untwisted) and Elastane external layers and Dyneema (untwisted) internal layer, but with different structures. These textile structures were analysed for their collision protection using the technique of ‘drop test’. The test was based on principle of energy absorption by the textile structure due to the impact of a hard surface with them. It was assumed that the higher is the energy absorbed by the textile structure, the smaller will be the impact to the wearer. It was found that the 3D structures can provide equivalent amount of impact protection as the commercial foam (Sample D). The flexible structures recover easily with the body movement, and provide a high level of comfort. The methods of drop-test including the results are discussed in this paper. The findings of this study suggested that an equivalent level of protection can be achieved with the use of 3D textile structures and higher amount of comfort for the rugby players. Hence, the 3D textile structures can be used as an alternative material to replace the commercial closed foam currently in use in the shoulder pad to achieve similar protection and improved thermal comfort.

Published: February 2017

Additive Manufacturing (AM), also known as 3D printing is an emerging technology in oral & maxillofacial surgery with respect to reconstructive bone surgery. Such treatment protocols often require customized implants to fulfill the functional and aesthetic requirements. Currently, such customized implants are being manufactured using AM technology. This paper describes a mandible defect of oral & maxillofacial surgery. The fracture and defect of the mandible inferior border is one of the serious complications during alignment and fixing of the implant. Reconstruction of such defects is daunting tasks. The case report describes a method based on Computer Aided Design (CAD) and AM for individual design, fabrication and implantation of a mandible inferior border. A 40-year old male meet an accident with rash drive. The patient specific customized implant is designed with patient Computed Tomography (CT) data. The CT images in Digital Imaging and Communication in Medicine (DICOM) file format is used to develop a 3D CAD model of customized implant. The implant is designed to maintain the symmetry of mandible from right to left. The designed implant model is manufactured by Fused Deposition Modelling (FDM) techniques with a biocompatible material. The patient mandible prototype model was manufactured by AM process, which is helpful for pre-planning of surgical procedures. For these pre-planning surgical procedures, a perfect fit obtained during surgery. The patient ultimately regained reasonable mandible contour and appearance of the face. 
Detection of Large Bodies of Water for Heterogeneous Swarm Applications
Authors: Champion Benjamin , Benavidez Patrick , Jamshidi Mo , Joordens Matthew
Published: February 2017

Multiple robot systems are becoming popular, as introducing more robots into a system generally means that the system is able to finish a task quickly, as well as making the system more robust. Generally, these systems are homogenous in nature as they are easier to build, test and conceptualise. More applications of these types of systems in a heterogeneous sense is becoming a must, as these robots are acting in more than one medium such as on land and underwater. In this paper a subsystem of a heterogeneous swarm is investigated where a land based robot is to drive up to the edge of a pool and stop autonomously, allowing for the transfer of an object from an underwater robot. To detect the edge of a pool an Xbox Kinect sensor is used as it was found that by using the IR feed of the camera the problem becomes significantly simpler.

Healing the ‘Scar’ of the Landscape: Post-Mining Landscape in Anglesea
Authors: Su Yang , Jones David
Published: February 2017

The nexus between environmental bio-remediation and environmental design, as it pertains to disused coal mining sites in Australia, is little investigated. Increasingly, many of these open cut extraction holes around south-eastern Australia, are becoming redundant as their resources are exhausted or non-economic viability creeps into the industry or are becoming management ‘nightmares’. The recently announced March 2017 cessation of the Yallourn Power Station and associated brown coal Open Cut, and the recent fires and insurance liability legal determinations of the Yallourn Open Cut are exemplar of the former and latter respectively.
This paper surveys the deeper bio-remediation and ecological transformative issues directly associated with the Anglesea brown coal Open Cut, and offers an ecological design lens insight as to possible treatments and scenarios that can be offered to guide the future use and management of the site. The lens demonstrates the richness that interdisciplinary design and applied research offers in assisting the healing and mediation of sites. The extraordinary nature and scope of the Anglesea coal mine site provides an opportunity to create a range of cultural attractions, natural succession treatments, natural bio-remediation strategies and educational opportunities. One scenario, for an Anglesea Lake Eco-Resort, proposes to incorporate an integrated Aboriginal cultural destination, performance centre, art installations and recreational venues, engaging the Anglesea community, visitors, researchers and students towards creating a vibrant and unique environment.
Hybrid Environmental-Media Facades
Authors: Moloney Jules , Globa Anastasia , Wang Rui
Published: February 2017

There is significant potential for responsive sun screening systems to improve the energy performance of large scale public and commercial buildings. However there has been minimal uptake, primarily due to the capital and maintenance costs. We propose that these costs can be offset by providing added value in three ways. (1) Development of a finer grained control interface for occupants to enhance individual comfort, which has been shown to improve worker productivity. (2) With a high granularity of panels and a control system that enables individual movement of each panel, the system can be re-purposed as a low resolution media screen to foster social interactions in urban settings. (3) Enabling a new movement-aesthetic for architecture of indeterminate states that coalesce and shift during the daily and seasonal cycles, thus enlivening the public face of architecture. To evaluate the feasibility of such hybrid responsive facades we are developing physical prototypes calibrated to real time simulation and control software. A initial proof-of-concept design explores the optimal configuration and geometry of the kinetic panels to enable the granularity required for a range of graphic and textural information, along with development of the actuator. We document progress to date on this research into hybrid environmental-media façades’.

Knowledge of Making Life: Design Pattern for Regenerative-Adaptive Design
Authors: Roös Phillip , Jones David
Published: February 2017

An astonishing intense fascination is under way in the design sciences, where the words of ‘living structures’ and ‘adaptive’ are being linked with ‘technology.  In part fuelled by the emergence of the Anthropocene discourse, these words are inspiring authoritative new insights into the workings of wild nature, humanity’s position and responsibility to planet Earth, and is being articulated through the rapidly increasing science of pattern theory. The new terminology is provoking the design sciences to seriously consider technologically-informed innovation in design and new possibilities including living technology, morphogenetic sequences, self-organisation, generative codes, biophilia, biomimetics and regenerative-adaptive design, opening the doors to a new era in ecology-informed design. The idea of design as an adaptive and transformation process, is at the core of the whole systems theory pioneered by Alexander in A Pattern Language (1977) and The Nature of Order (2001-2005).  Alexander positioned this hypothesis in generative codes supported by morphogenetic sequences.  Drawing upon Alexander’s The Nature of Order (2001-2005), this paper advances a regenerative-adaptive design theory (Roӧs, 2016), towards a holistic integrated design method that incorporates the principles of regenerative design with an adaptive pattern language that re-establishes human wholeness with nature and offers relevant strategies towards resilience; in essence creating a living technology.

Published: February 2017

This paper focuses on the design of an evaluation made to a large-scale virtual reality micro-robotic cell injection training system. The aim of the evaluation is to empirically investigate the usability and effectiveness of three distinct display configurations and the input controller employed in the system. The data was gathered through a set of experiments with human participants. Participants’ performance against metrics such as success rate and magnitude of error was considered in the evaluation. For the experiments, participants were randomly divided into six equal sized groups where each group was provided with a specific combination of display configuration and haptic guidance mode. The participants performed ten injections and the time and position of the virtual micropipette tip were recorded. Data was analysed using descriptive statistics and performance comparison between groups was conducted. Additionally three groups also underwent two subsequent sessions, training and post-training, as a basis to evaluate the effectiveness of the training with haptic guidance by comparing participants’ performance before and after the training session. The implementation of the designed evaluation has contributed to the conclusions drawn which suggest the proposed large-scale virtual reality system as a feasible training tool for micro-robotic cell injection procedure, and recommendations for future work are proposed.

Authors: Novak James , Loy Jennifer
Published: February 2017

This paper evaluates the impact of visual coding on the Industrial Design and 3D Design disciplines, in particular the role it plays in developing new products and services that would previously require interdisciplinary teams, or significant training beyond the scope of these disciplines into text-based coding and electrical engineering. The professional practice of designers working at the intersection of product design and coding is discussed, and design education evaluated in relation to the opportunities of electronics and visual coding. Quantitative research data is provided to support an argument that visual coding can enable designers to control their designs in new ways throughout the design and prototyping process.

Authors: Mohammed Mazher Iqbal , Mohan Meera , Das Anirudra , D. Johnson Mitchell , Singh Badwal Parminder , McLean Doug , Gibson Ian
Published: February 2017

In this study we aim to investigate recycling of waste plastics products into filaments for use in a typical FDM 3D printing system. We investigate the parameters relating to control of the filament thickness to a variety of different plastic types, which include HDPE and ABS. Following filament generation, parameters were investigated to optimise the print parameters to produce a variety of demonstration models, which test the print resolution. Results suggest that the proposed supply chain can allow for highly repeatable ABS and HDPE filament generation with a diameter of 1.74 ± 0.1mm and 1.65 ± 0.1mm respectively. Ultimately, the production of usable filaments can provide a viable means of consuming waste plastics and reducing the burden of increased landfill.

Published: February 2017

3D printing and Building Information Modelling (BIM) are two technologies that have become increasingly popular and changed a wide variety of applications in a significant manner. 3D printing enables the design, prototyping and manufacture of items that were previously impossible or infeasible to do. Similarly, BIM is changing the way building and civil infrastructure projects are conceived, designed, delivered and maintained with a push towards a digital, wholly collaborative construction environment.

This paper examines how 3D printing and BIM can be used in a complimentary manner to help visualise and communicate important aspects of a project to the relevant stakeholders and personnel involved. By using the BIM model that has been developed for a specific project and segmenting key components of this model we can then use 3D printers to create a scaled model of the job and educate the concerned parties in the construction methodology, main risk areas, and ongoing concerns for maintenance and end-of-life deconstruction. 
Scheduling Algorithm for Real-Time Embedded Control Systems using Arduino Board
Authors: Thirunavukkarasu Gokul Sidarth , Krishna Ragil
Published: February 2017

The time taken for the scheduling task in a control system to reduce the traffic within the system is one of significant field of research in modern era. There are different control systems that require time scheduling such as elevator control system, traffic control system and train control system. Currently, there are unique control logic strategies adopting scheduling algorithm that are implemented in real time systems like earliest deadline first and ant colony optimization. At the same time, the disadvantages possessed by them are the exponential dip in the performance ratio due to over loading. Despite of all the available resources there are many issues faced such as congestion in traffic networks due to non-adaptive scheduling algorithms, etc., which led to several misfortunes and danger for human life. Hence an improved algorithm that increases the efficiency of the system is required to validate the processing time and the deadlines. Our research is focused on validating a proposed idea of using Arduino microcontroller to implement the different scheduling tasks and validate the efficiency of the algorithm to optimize the results of the system. This take cares of assigning the critical paths which priorities the tasks and focuses on reducing the scheduling time. This rapidly increases the processing speed and efficiency of the algorithm. We plan to use the Arduino board which has an inbuilt error detection algorithm that helps in checking whether the time scheduling is done effectively. In the initial phase of the project we develop and fabricate the hardware design using CAD design software packages like Solid Works. This is later employed with suitable environmental interfaces like, sensors and microcontrollers that can work in an adaptable environment as per requirements to validate the scheduling algorithm. The scheduling algorithm can also be used for controlling the current flow and power storage which will contribute a lot in the power consumption aspect. Graphical data interpretation of various algorithms from the past literature is observed and few selected ones are to be implemented in the experimental set up that is built as an initial proof of concept. By analyzing the results from the simulations carried out using the Altera FPGA board with VHDL and Arduino it is clear that we obtain better results using the Arduino board. Finally, to have an extensive study on different intelligent control logics that are used in the above mentioned control systems, we use the prototyped miniature model of an elevator system and a train control system to validate the different disk scheduling approaches like First Come-First Serve (FCFS), Elevator (SCAN) and ant colonization to solve the discrete combinational optimization of the scheduling logic. Initial validation of the system focuses on the effectiveness of using the ant colonization strategies to enhances the efficiency of the scheduling algorithm and optimize it for real time application.

Authors: Boer Nicholas de , Abdi Hamid , Fielding Michael , Nahavandi Saeid
Published: February 2017

This paper presents segmentation and feature extraction of human gait motion. The methodology of this paper focuses on segmenting ‘XYZ’ position curves, in reference to time of gait motion based on the velocity or acceleration of the movement. The extracted features include amplitude, time, and equally spaced sample data, maximum and minimum for each segment. The results can be used for reconstruction of a viable dataset that is critical for simulation and validation of human gaits. We propose a method to enables the fitting of the same curve with limited data. Such data sets may prove valuable for studying impairments and improving simulations of rehabilitation tools, and statistical classification for researchers worldwide.
Thermal Stress Flow Analysis in Fabrication of Acetabular Shells Using SLM
Authors: Khorasani Amir Mahyar , Gibson Ian , Goldberg Moshe , Masoud Movahedi Mohammad , Littlefair Guy
Published: February 2017

Additive Manufacturing (AM), more popularly known as 3D Printing, is a process for producing functional artifacts by adding layers of materials from data generated directly from 3D solid CAD models. Additive Manufacturing (AM) is the formalized term for what used to be called Rapid Prototyping and what is commonly referred to as 3D Printing. The key to how AM works is that parts are made by adding layers of material; each layer corresponding to a thin cross-section of the part derived from the original CAD data. Although most AM machines produce parts using polymers, there are an increasing number of machines that can directly fabricate in metals. The majority of these machines fabricate from raw material in powder form using a directed energy beam to create a local melt zone. Total hip replacement is recommended for people who have medical issues related to excessive wear of the acetabular, osteoarthritis, accident or age. Researches have shown that large numbers of hip arthroplasties (where the articular surface of a musculoskeletal joint is replaced), hip remodelling, or realignment are carried out annually and will increase in the next few decades. Manufacturing of acetabular shells by using AM is a promising and emerging method that has a great potential to improve public health. Lost wax casting or investment casting is currently used to produce acetabular shells followed by lengthy and complex secondary processes such as machining and polishing. Living organs and medical models have intricate 3D shapes that are challenging to identity in X-ray CT images. These images are used for preparing treatment plans to improve the quality of the surgeries regarding waiting and surgery time per procedure and care regime. For instance, a limited number of hip replacement procedures can be carried out on each acetabulum due to a decrease of bone thickness. Rapid prototyping is a suitable treatment planning tool in complex cases to enhance the quality of surgical procedure and provide long-term stability that can be used to customize the shape and size of the acetabular shell. In this paper, to analyse the manufacturing of a prosthetic acetabular shell, built-up lines resulting from a thermal stress flow and process stopping during the selective laser melting (SLM) AM process, with regarding Gibbs free energy, interfacial energy, and equilibrium temperature will be discussed. Geometrical measurements showed 1.59% and 0.27% differences between the designed and manufactured prototype for inside and outside diameter respectively. Experimental results showed that thermal stress flow in outer surfaces are compressive, but for inner surfaces are tensile, so built-up lines in inner and outer surfaces appear as a groove and dent respectively. The results also indicate that SLM is an accurate and promising method for fabrication of acetabular cup.
Urbanheart Surgery – a Collaborative Interdisciplinary Design Studio
Authors: J. Rollo , Y. Esteban
Published: February 2017

The following paper presents an interdisciplinary design studio program at the School of Architecture and Built Environment, Deakin University, referred to as the ‘UrbanHeart Surgery’. This is a design based research forum that attempts to facilitate a landscape of decision-making that stimulates an integrated approach to design within the urban context.

The Urbanheart program has developed into a very successful teaching, research and public/community relations program. It has not only secured an ongoing relationship with various planning authorities, but its core of industrial partnerships has expanded to include four regional councils (Bendigo, Ballarat, Geelong, Surfcoast and Warrnambool), three metropolitan municipalities (Melbourne City, Port Phillip, Wyndham and Maribyrnong) and close links with various Victorian State government departments.

The program actively integrates postgraduate students from Architecture, Urban Design, Landscape Architecture and Planning. The different scales of resolution at which the unit operates would welcome further integration with students from Mechanical Engineering, Art and Design, Information Technology and Environmental Science.
Wearable smart device incorporating real-time clock module and alcohol sensor
Authors: Ng David
Published: February 2017

In this work, we designed and built a wearable device with battery-saving and alcohol-sensing functions. The motivation for this device was to deliver a proof-of-concept wearable and functional device which alerts the user of possible alcohol breath level above a threshold limit and can be worn for an extended time due to battery saving features. It was built using a combination of Arduino electronics and sensors, and encased in 3D-printed ABS bracelet. A 4-digit 7-segment LED display on board is used to display time which is tracked using a real-time clock module. A 3-axis accelerometer determines the orientation of the device and activates the display only when it is held in a specific orientation by the user. An example is when two axes are normal to the gravitational pull while a single axis is in line with gravity to simulate users raising their arm parallel to the ground. A slight tolerance in the setting ensures that the threshold for activation is not overly strict. This will ensure that the LED display is activated over a narrow range of orientations. The alcohol sensor is sensitive to alcohol content in the air. The threshold for detection can be changed and calibrated to the user specific needs. The alcohol sensor is slightly sensitive to humidity and very sensitive to alcohol. It has been tested with ethanol, wine and beer with 95%, 12.5% and 4.55% alcohol content, respectively. Because the alcohol sensor works by using a resistor that continuously pulls current and detects changes in resistivity due to adsorption of alcohol molecules, it consumes a lot of power when turned on continuously. In order to conserve power, the sensor can be activated only when the device is oriented in a specific position or when the user pushes a button. An Arduino Nano board is used to reduce the overall size of the device. It is powered using an external 5V battery via a mini-USB connector. In order to reduce the number of IO pins used, the RTC, LED and accelerometer were configured to use I2C interface connections. A default SCL clock speed of 100 kHz is used and the component IOs are connected to a common SDA line which terminates at one analog pin. In normal operation, the RTC is configured to read time continuously at one second interval. It is preprogramed with the correct date and time prior to operation of the device.
Whose Job is it? 3D Scanning Design for Innovation
Authors: Little Chris , Loy Jennifer
Published: February 2017

There are often references in design education to the idea that design graduates of the future will be working in jobs that do not yet exist. There are therefore opportunities emerging that are not currently recognised as within the designers’ purview. One such area of growth is emerging out around the potentials created by technological developments relating to 3D scanning. This technology is proving to be a catalyst for not only new product outcomes but also innovations in thinking and practice. This is particularly in relation to new workflows that are permeating traditional discipline boundaries. The wide range of advances in digital scanning over the last twenty years have resulted in a myriad of complex capabilities, and the potential of these technologies to support innovation in practice, outcome and thinking are only beginning to be explored. Examples of these explorations are considered in this paper, demonstrating how they can provide a basis for redirecting design for a future of digital immersion. This paper questions the rigour in current approaches to teaching 3D scanning technologies in design education.  It provides an argument that 3D scanning is part of a rapidly evolving suite of digital enablers that are challenging conventional design practice and suggests that educators need to more effectively research and understand the innovations that 3D scanning technologies can inspire. 
Enhancing student learning with case-based teaching and audience response systems in an interdisciplinary Food Science course
Authors: Giacalone Davide
Published: February 2017

A growing body of research in higher education suggests that teachers should move away from traditional lecturing towards more active and student-focus education approaches. Several classroom techniques are available to engage students and achieve more effective teaching and better learning experiences. The purpose of this paper is to share an example of how two of them – case-based teaching, and the use of response technologies – were implemented into a graduate-level food science course. The paper focuses in particular on teaching sensory science and sensometrics, including several concrete examples used during the course, and discussing in each case some of the observed outcomes.

Overall, it was observed that the particular initiatives were effective in engaging student participation and promoting a more active way of learning. Case-base teaching provided students with the opportunity to apply their knowledge and their analytical skills to complex, real-life scenarios relevant to the subject matter. The use of audience response systems further facilitated class discussion, and was extremely well received by the students, providing a more enjoyable classroom experience.

Undergraduate psychology students rated expectations of a bogus professor (randomly designated a man or woman and hot versus not hot) based on an online rating and sample comments as found on RateMyProfessors.com (RMP). Five professor qualities were derived using principal components analysis (PCA): dedication, attractiveness, enhancement, fairness, and clarity. Participants rated current psychology professors on the same qualities. Current professors were divided based on gender (man or woman), age (under 35 or 35 and older), and attractiveness (at or below the median or above the median). Using multivariate analysis of covariance (MANCOVA), students expected hot professors to be more attractive but lower in clarity. They rated current professors as lowest in clarity when a man and 35 or older. Current professors were rated significantly lower in dedication, enhancement, fairness, and clarity when rated at or below the median on attractiveness. Results, with previous research, suggest numerous factors, largely out of professors’ control, influencing how students interpret and create professor ratings. Caution is therefore warranted in using online ratings to select courses or make hiring and promotion decisions. 
A Literary Approach to teaching English Language in a Multi – Cultural Class - Room
Authors: Choudhary Sanju
Published: February 2017

Literature is not generally considered as a coherent branch of the curriculum in relation to language – development in either mother tongue or foreign language – teaching. As teachers of English in Multi cultural Indian class rooms we come across students with varying degree of competence in English language learning. Though, language learning is a natural process for natives but the Students of other languages put in colossal efforts to learn it. Despite   their sincere efforts they face challenges regarding Pronunciation, Spelling and Vocabulary. The Indian class rooms are a microcosm of the larger society, so teaching English language in a manner which equips the students to face the cut-throat competition has become a necessity and a challenge for English language Teachers. English today has become the key determinant for getting success in their career. The hackneyed and stereotypical methods of teaching are not acceptable now. Teachers have no longer remained arbitrary dispensers of knowledge but they are playing the role of a guide and facilitator for the students. Teachers of English are using innovative ideas to make English language teaching and learning interesting and simple. Teachers have started using the literary texts and their analysis to explore and ignite the imagination and creative skills of the students. One needs to think and rethink the contribution of literature to intelligent thinking as well as its role in the process of teaching – learning. My paper would, therefore, be an attempt at exploring the nature of the literary experience in the present day class rooms; and the broader role of literature in life.
Digital literacy matters. Increasing workforce productivity through blended English language programmes.

The three Rs, the ability to read, write and do basic arithmetic have traditionally been measured as indicators of knowledge and ability to communicate, and in turn, a predictor of success at workplace. However, survey any place of work today, and we see that the traditionally held literacy skills do not suffice; newer forms of literacies that go beyond the ability to decode print, like the skill to communicate, interact, solve complex problems, analyse, judge, evaluate, collaborate, construct, create, and to use information technology/ digital tools, are now considered essential contributors to enhanced employability opportunities as well as workplace success.
The role of information literacy competence and higher order thinking skills to develop academic writing in Science and Engineering learners
Authors: Kumari B. Kranthi
Published: February 2017

The English syllabus for learners pursuing engineering courses includes teaching writing as one of the objectives. Learners who enroll for these courses are not equipped with the general writing skills that they should have mastered at the entry level. In this context, a study was organized to develop academic writing skills of the undergraduate learners who are pursuing engineering courses.  The study focused on raising awareness in the learners of the nature and characteristics of academic texts in order to develop academic writing skills. The study also emphasizes that involving the learners in the cognitive processes of writing that include defining the rhetorical problem, identifying the rhetorical situation, the audience and setting goals for writing, planning for the text by generating and organizing ideas is necessary. The study further suggests that discussions between learners and teachers regarding the construction of a text and the way language works in various text types facilitates better writing.
