Abstract: A New Generation Spherical Actuator is designed for rear view mirrors in modern automobiles. The present paper portrays the design of a bistable compliant locking mechanism for this New Generation Mirror Actuator. A Functionally binary pinned-pinned segment is also designed for bistability. Discussion on related topics like bistable mechanisms, compliant mechanisms and rigid body mechanisms becomes the foundation for this research. A testing rig is constructed here to test the design. The design met the required attributes to be compliant and bistable, and it also emphasized on decreasing the number of parts in the whole assembly of the spherical actuator to minimize the total production cost.

Abstract: Digital disruption offers an innovative opportunity to address housing affordability issues through the use of market design theory and two-sided matching markets. The purpose of this paper is to scope a model for how “uberisation” can revolutionise the traditional apartment delivery model in Australia, leading to improved housing affordability. This paper uses semi-structured interviews with operators of online real estate platforms and deliberative developers to examine how the principles of “uberisation”, that is two-sided matching markets, are driving innovation in the apartment supply process. Findings confirm that real estate internet platforms and deliberative developers innovators are informed by the benefits of aggregating demand to reduce development risk, thus enabling apartments to be provided at a substantially lower price than by traditional methods. The number of interviews is small reflecting the limited number of market actors currently engaged in the innovations investigated. This research is innovative as it introduces theoretical understandings gained from market design theory and applies those concepts to disrupt the apartment development process.

Abstract: A simplified approach for the fabrication of localised surface plasmon resonance (LSPR) sensors based on gold nanorods (GNRs) is described and validated in a model immunoassay for the activated leukocyte cell adhesion molecule (ALCAM) cancer biomarker. Towards improving on standard bottom-up LSPR sensor fabrication methodologies, we demonstrate that GNRs bioconjugated with monoclonal antibodies can be readily covalently immobilized onto silanized glass substrates to yield highly sensitive LSPR sensors. To maximise the performance of the proposed sensors, mixed polyethylene glycol adlayers were optimized in regards to the bioconjugation of monoclonal antibodies using the standard carbodiimide chemistry. In the optimal condition, the ALCAM GNR LSPR sensors yielded a sensitivity of 330 nm per refractive index and allowed the detection of the ALCAM antigen concentration down to 15 pM. This simple fabrication method could foster the implementation of LSPR sensors in the immunoassay field.

Abstract: Electrical power is considered as a significant part of contemporary life, and an essential element for development. Fossil fuels have been utilized since the beginning of the twentieth century for electricity generation. However, fossil fuels depletion at the escalating pace as well as their formidable negative implications upon ecosystem contributed to increasing interest in harnessing renewable energy sources for producing electric power to meet the growing demand worldwide. In Iraq, the electrical supply is not sufficient to supply 12 hours a day of electricity. Many rural areas, particularly their schools are suffering from the electricity shortage such as Umm Qasr Primary School that located 20 km away from the city centre of Karbala city in the middle of Iraq. In order to overcome this issue, this paper proposes a hybrid system which relies on renewable resources and the local grid to electrify Umm Qasr Primary School. Various combinations of energy resources have been analysed by using HOMER software to estimate an optimum hybrid system. The analysis illustrates that the optimal configuration of the projected system is composed of 22.4 kW PV modules, 59 batteries, and 5738kWh purchased from the local grid which has reduced the net present cost(NPC)from US$ 163791 the current situation to US$60,420 for the proposed system. The simulation findings also demonstrate that detrimental emissions have been reduced significantly.

Abstract: In recent years, downscaled coordinate measuring machines (CMMs) are in demand and bring challenges to the development of micro/nanoscale probes for a variety of microscale structure measurement applications. A working prototype apparatus is developed in which a microspherical optical fiber probe tip is created from a strand of standard single mode silica optical fiber using an electric discharge technique. The Taguchi method has been used to investigate the general effects of probe fabrication conditions that result in controllable fabrication of a quality probe tip. With proper control of the process parameters, spherical optical fiber probe tips with the desired diameters in the range of 133–360 μm with a diameter variance within 3% and minimum spherical tip center offset of about 2.2 μm have been achieved. An economical and flexible technique for the fabrication of a quality microspherical probe for micro/nano-CMM application is developed in this work.

Abstract: Piezoelectric composites comprising an active phase of ferroelectric ceramic and a polymer matrix have recently found numerous sensory applications. However, it remains a major challenge to further improve their electromechanical response for advanced applications such as precision control and monitoring systems. We here investigated the incorporation of graphene platelets (GnPs) and multi-walled carbon nanotubes (MWNTs), each with various weight fractions, into PZT (lead zirconate titanate)/epoxy composites to produce three-phase nanocomposites. The nanocomposite films show markedly improved piezoelectric coefficients and electromechanical responses (50%) besides an enhancement of ~200% in stiffness. The carbon nanomaterials strengthened the impact of electric field on the PZT particles by appropriately raising the electrical conductivity of the epoxy. GnPs have been proved to be far more promising in improving the poling behavior and dynamic response than MWNTs. The superior dynamic sensitivity of GnP-reinforced composite may be caused by the GnPs' high load transfer efficiency arising from their two-dimensional geometry and good compatibility with the matrix. The reduced acoustic impedance mismatch resulting from the improved thermal conductance may also contribute to the higher sensitivity of GnP-reinforced composite. This research pointed out the potential of employing GnPs to develop highly sensitive piezoelectric composites for sensing applications.

Abstract: Piezoelectric composites are hybrid materials primarily consisting of polymer matrices and micro-sized particles of ferroelectric ceramic. While incorporating high-fraction ceramic particles into composites is indispensable to meet the ever increasing requirement of sensitivity, it is a great challenge to achieve such a high concentration due to processing difficulties. In this study, we developed piezoelectric composites of 0-3 geometry containing 95 wt% (∼73 vol%) lead zirconate titanate particles by modifying the surface of lead zirconate titanate particles with isophorone diisocyanate and polyoxyalkyleneamine (J2000) and compounding them with epoxy resin. The functional groups of J2000 molecules covalently grafted onto the particle surface can react with the matrix, thus creating a robust linkage between the matrix and the particles. This improved the particle dispersion and the interface, enabling the development of a superior composite film with high lead zirconate titanate fractions. Modified piezocomposites can save up to 75% poling time at 75% lower voltage in comparison with the unmodified s le as well as previous studies. The remarkable improvement is indebted to the two-stage interface modification process and the layer-by-layer fabrication method.

Abstract: Cell culture and cell scaffold engineering have previously developed in two directions. First can be ‘static into dynamic’, with proven effects that dynamic cultures have benefits over static ones. Researches in this direction have used several mechanical means, like external vibrators or shakers, to approximate the dynamic environments in real tissue, though such approaches could only partly address the issue. Second, can be ‘2D into 3D’, that is, artificially created three-dimensional (3D) passive (also called ‘static’) scaffolds have been utilized for 3D cell culture, helping external culturing conditions mimic real tissue 3D environments in a better way as compared with traditional two-dimensional (2D) culturing. In terms of the fabrication of 3D scaffolds, 3D printing (3DP) has witnessed its high popularity in recent years with ascending applicability, and this tendency might continue to grow along with the rapid development in scaffold engineering. In this review, we first introduce cell culturing, then focus 3D cell culture scaffold, vibration stimulation for dynamic culture, and 3DP technologies fabricating 3D scaffold. Potential interconnection of these realms will be analyzed, as well as the limitations of current 3D scaffold and vibration mechanisms. In the recommendation part, further discussion on future scaffold engineering regarding 3D vibratory scaffold will be addressed, indicating 3DP as a positive bridging technology for future scaffold with integrated and localized vibratory functions.

Abstract: In this chapter, the use of two images, the near infrared image and the color image, from a bi-camera machine vision system is investigated to improve the detection of the citrus fruits in the image. The application has covered the design of the bi-camera vision system to align two CCD cameras, the online acquisition of the citrus fruit tree image, and the fusion of two aligned images. In the system, two cameras have been registered with alignment to ensure the fusion of two images. A fusion method has been developed based on the Multiscale Decomposition Analysis (MSD) with a Discrete Wavelet Transform (DWT) application for the two dimensional signal. In the fusion process, two image quality issues have been addressed. One is the detail noise from the background, which is bounded with the envelope spectra and with similar spectra to orange citrus fruit and spatial variance property. The second is the enhancement of the fundamental envelope spectra using two source images. With level of MSD estimated, the noise is reduced by zeroing the high pass coefficients in DWT while the fundamental envelope spectra from the color image are enhanced by an arithmetic pixel level fusion rule. To evaluate the significant improvement of the image quality, some major classification methods are applied to compare the classified results from the fused image with the results from the types of color image. The misclassification error is measured by the empirical type errors using the manual segmentation reference image.

Abstract: In this paper, an image fusion is presented to improve the citrus identification by filtering the incoming data from two cameras. The citrus image data has been photographed by using a portable bi-camera cold mirror acquisition system. The prototype of the customized fixture has been manufactured to position and align a classical cold mirror with two CCD cameras in relative kinematic position. The algorithmic registration on the pairwise images has been bypassed by both the spatial alignment of two cameras with recourse of software calibration and the triggering synchronization in temporal during the photographing. The pairwise frames have been fused by using the Daubechies wavelets decomposition filters. The pixel level fusion index rule is proposed to combine the low pass coefficients of the visible image and the low pass coefficients of the near-infrared image convoluted by the complementary of entropy filter from the visible low pass coefficients. In the study, the fused artifact color image and the non-fused color image have been processed and compared by some classification methods such as low dimensional projection, self-organizing map and the support vector machine.
