The interaction between the virtual world and the real world has received continuous attention in recent years, and this type of interaction has often been found unidirectional or asynchronous. By reviewing the literature, this study explained our view of the virtual world, as well as the necessity of media and the directional connection in the interaction of the two worlds. To validate our design concept, we created a wall in the virtual world that can be instantly synchronized and interact with the monitor in the real world. Based on our findings in the design process, we also proposed applying the concept to more senses in the future.

The matching situation with AND operations between two parties is a common application in card-based protocols, and it is known to provide a non-embarrassing confession of love. This means that the other party does not know whether the input was 0 or 1, which is said to avoid embarrassment. In this paper, we consider an extended AND protocol that extends the usual AND operations with two input choices, 0 and 1, to allow the input of a third value, “indefinite,” which is neither 0 nor 1. Considering the continuity of the protocols, it is better to design them to satisfy the transitivity law, and in practice, we need to deal with the classification of three-element semigroups. We attempted a complete classification with restrictions to have a local AND structure, and found that except for trivial examples and considerations of the algebraic isomorphism, we could reduce the classification to only seven cases. These include cases of three-valued logic by Bochvar and Lukasiewicz respectively. We also discuss some examples applied to the card-based protocols that have been devised. The examples are based on the same pattern cards with indistinguishability on the backside, which is another card protocol different from the general encoding rules.

In-network caching is a technology that enables intermediate routers to store contents. Clients can download the contents from the routers in addition to content servers. Considering optimal placement of servers and contents leads to improve responsiveness and save network resources. This paper discusses joint optimization of server and content placement problems for in-network caching. We formulate integer linear programming to simultaneously determine the location of content servers and content caching. Through numerical experiments, we examine the performance of the joint optimization.

Android operating system adjusts its screen view orientation based on the angle to the gravity of the device. This function has kept similar behavior without large modification for a decade. We think that this implementation has room for improvement. For example, this implementation is too pessimistic for some users and makes a user wait for a while for its screen's view rotation after the device rotation. In this paper, we propose a method for quickly adjusting screen orientation. The proposed method predicts the angle of the device in the near future from the recently measured acceleration. We then show that our proposed method can adjust the screen view orientation sooner by 0.38 s than the original implementation and its negative effect of miss rotation is small.

Path planning is the research focus of robot development and design. As technology advances, mobile vehicles for various jobs are used in different environment. Therefore, it is an important research to plan an optimal path that is able to avoid obstacles and consider time and distance to reach the goal. In this paper, to improve the efficiency of mobile vehicle path planning, the Voronoi diagram is used to describe the map, and the shortest path tree is built by Dijkstra algorithm. Re-planning path task is activated when moving obstacles approach the mobile vehicle. The collision-free A* algorithm that take account of the directions and positions of the moving obstacles will effectively avoid collisions and find optimal path according to the shortest path tree. In the simulation results, there are several random moving obstacles in the map to simulate the complex dynamic environment. The mobile vehicle could reach the goal without any collisions, and only add a small amount of time and distance.

When setting up a terrestrial laser scanner near the target building and performing 3D measurement, the return measurements get corrupted because of the reflectivity and transparency of the glass objects. The discrimination of reflections and indoor points from the outdoor environment is a challenging task. As the first step of removing these erroneous measurements, it is important to detect these glass planes framed in the building façade. In this study, we propose an unsupervised segmentation approach in combination with the threshold of Gaussian distribution to extract transparent and reflective glass planes from point clouds with intensity attributes. For practical validation, our approach is evaluated on two scan points of a building with many glass components.

Heart disease poses a great threat to the health of an individual and even leads to sudden cardiac death, and hence a ubiquitous and portable tool for early detection and warning is of significant value. Benefiting from the speedy advance of sensor technology, artificial intelligence, and internet of things, we have developed an intelligent system that can remotely collect heart sounds, process the signals, and predict common cardiac diseases with the trained machine learning model. In this study, we detail our designed smart stethoscope and show the system architecture and its components. Besides, initial results demonstrate its power.
