The goal of bio-inspired is to resolve human problems by studying and mimicking the characteristics of organisms or design elements which can be found in nature. Wireless sensor networks are used in a variety of fields but have limited network lifespans, so various research is being performed on the subject. In particular, research is being performed on observing and modeling the behavioral principles of various organisms to use in bio-inspired algorithms for efficient routing techniques in large-scale networks. In this research, we studied the pheromones used in ant communication and designed the techniques for energy efficiency improvement and traffic distribution by applying them to the proposed network. We designed biomimicry technology called the Wireless Sensor Networks Based on Bio-inspired algorithms, and by analyzing and applying the similarities between communication systems and biological systems, our system was able to show improved performance in terms of extended network lifespan, optimized path selection, etc. In simulation results, the proposed routing algorithm has a short information collection time and low energy consumption, and through this it is able to maximize network energy efficiency.

Maxillofacial tumor resection is often dependent on the expertise of the surgeon performing the operation. This study wants to be a first exploration of the role that commercial mixed reality headsets could have in this field. With this purpose in mind, a mixed reality Head Mounted Display (HMD) application is proposed to ease this task and provide a training tool. Due to the invasiveness of the operation, a marker-less registration has been considered as advantageous and therefore a pattern recognition algorithm has been adopted for properly placing a segmented PET-CT scan over the target face. To document the validity and appreciation rate of such a system, groups of physicians and engineers were asked to evaluate and assess the resulting prototype according to the standard ISO-9241/110. The application showed a noticeable accuracy of millimeters, consistent with other biomedical studies, due to intrinsic limitations of the device. Nonetheless, the remarkably positive feedbacks collected from both groups suggest high interest in further work.
The signal achieved by accelerator in the process of the hard-layer penetration is a typical non-stationary random signal with very large peak pulse amplitude, quite short action time and blurry local characteristic. ...

Fingertip's motion is an important input channel of Human-computer-Interaction in Augmented Reality, but HoloLens' depth-image is not accessible nowadays. In this paper, a precise and fast fingertip tracking algorithm is proposed. Firstly, we get 2D fingertip's position from monocular camera video stream by segmentation method. Then, we setup a spherical coordinate system according to the hierarchical finger-hand-arm's motion model to project the fingertip's motion in 2D image to 3D space. Meanwhile, a composite Kalman motion model is designed for 3D tracking prediction and smoothing. With the 3D Kalman filter's help, high-precise fingertip motion is projected back to the 2D space, to promote the fingertip detection of the next state. The fingertip detection is performed in a small neighbourhood of the predicted position. Experiments show that the accuracy and performance are both promoted than traditional fingertip detection method. The algorithm is applied in HoloLens AR gesture interaction system and can provide accurate and fast gesture tracking.
