- The ever-increasing demand for higher productivity, lower cost and improved safety continues to drive the advancement of manufacturing technologies. As one of the key elements, human-robot collaboration (HRC) envisions a workspace where humans and robots can dynamically collaborate for improved operational efficiency while maintaining safety. As the effectiveness of HRC is affected by a robot's ability to sense, understand and forecast the state of the collaborating human worker, human action recognition and motion trajectory prediction have become a crucial part in realising HRC. In this chapter, deep-learning-based methods for accomplishing this goal, based on the in-situ sensing data from the workspace are presented. Specifically, to account for the variability and heterogeneity of human workers during assembly, a context-aware deep convolutional neural network (DCNN) has been developed to identify the task-associated context for inferencing human actions. To improve the accuracy and reliability of human motion trajectory prediction, a functional unit-incorporated recurrent neural network (RNN) has been developed to parse worker's motion patterns and forecast worker's future motion trajectories. Collectively, these techniques allow the robot to answer the question: "which tool or part should be delivered to which location next?", and enable online robot action planning and execution for the collaborative assembly operation. The methods developed are experimentally evaluated, with the collaborative assembly of an automotive engine as a case study.

- The application of carbon nanotubes (CNTs) for wearable sensing device fabrication is an interesting area, attracting sustained scientific and technological interest. Acquisition of information from wearable technologies is considered a cornerstone in person-centered health informatics, because of its independence, currency, and timeliness. The unique physical and chemical properties (such as high aspect ratio, ultralight weight, high mechanical strength, high electrical conductivity, and high thermal conductivity) of CNTs make them an attractive nanomaterial for wearable sensor fabrication. Extensive efforts will continuously be made in both academia and industry in the research and development of wearable CNT sensors to enhance their function, flexibility, energy saving, and longevity. We will discuss recent advances in the design and application of wearable devices based on CNT materials for sensing, especially in the fields of medical equipment, motion detection, and environmental sensor.

- Screen printed electrodes with conductive ink made of Carbon and Ag/AgCl were tested for polarization potentials and electrode impedances. In 30 minutes the mean decrease of polarization potential was 2 mV. The electrode impedances at 10 Hz were between 670 and 250 Ohms. These characteristics seem adequate for personalized health care applications.

- This study aimed at investigation of the response of the human thorax under various loading conditions. For this purpose an FE thorax model was developed based on the human anatomical structures. The human thorax consists of ribs, thoracic vertebrae and intervertebral discs, a sternum, costal cartilages and internal organs. Material properties used in this study were based on the published literature. The FE model was used to simulate the phenomenon of thorax compression. The simulations were carried out in different configurations, including the three-point bending of single rib and frontal impacting with a cylinder to a complete thorax at low speed. The results from simulations were compared with the impact responses obtained from biological tests, such as 3-point bending tests and rib structural tests. The entire thorax model was then tested by simulation of volunteer test. The responses predicted by the simulation showed a good biofidelity.

- Recently, solar system has gained a rapid development in many countries because it is clean and sustainable. Many solar systems including the solar photovoltaic/loop-heat-pipe (PV/LHP), solar loop-heat-pipe (LHP), solar photovoltaic/micro-channel heat pipe (PV/MCHP) system, and solar thermal facade system (STF) have been designed for energy saving. To assess these systems’ performance, there are many approaches such as energy and exergy assessment which is used in this chapter to analyze their performance. Besides the system design, the authors set up dedicated experimental models in combination with computer models to test the systems’ performance. Furthermore, some systems are compared with the conventional system, and the performance of these solar systems is better than the conventional system. In addition, these solar systems are applied in many real buildings and their performance is examined, the results show that the solar systems have more potential to boost the building energy efficiency and create the possibility of solar development in buildings. © 2019, Springer Nature Switzerland AG.
