In this paper we introduce a novel online path planning method that mimics the human sense of navigation for finding a path between the current location (the ‘origin’) and the destination point. Most pedestrian simulation systems pre-compute a minimum cost (e.g. shortest length) path. Such an approach implies that the simulated agents have perfect knowledge of the infrastructure. Moreover, pre-...

THz band is envisioned to be used in 6G systems meet the ever-increasing demand for data rate. However, before an eventual system design and deployment can proceed, detailed channel sounding measurements are required understand key characteristics. In this paper, we present a first extensive set of urban outdoor environments that ultra-wideband, double-directional where both transmitter receive...

Title of thesis: DEVELOPMENT OF A REAL-TIME HIERARCHICAL 3D PATH PLANNING ALGORITHM FOR UNMANNED AERIAL VEHICLES Matthew David Solomon, Master of Science, 2016 Thesis directed by: Dr. Huan Xu Department of Aerospace Engineering Unmanned aerial vehicles (UAVs) frequently operate in partially or entirely unknown environments. As the vehicle traverses the environment and detects new obstacles, rap...

due to their advantages, omni-directional mobile robots have found many applications especially in robotic soccer competitions. however, omni directional navigation system, omni-vision system and kicking mechanism in such mobile robots have not ever been combined. this situation brings the idea of a robot with no head direction into existence, a comprehensive omni directional mobile robot. such...

The presented two-campus transport problem (TCTP) is a pickup-anddelivery scheduling problem. It is a problem of a college with two campuses located at two different cities. Lecturers living in one city should sometimes teach at the other city campus. The problem is that of transporting N lecturers from one campus to the other, using a fleet of k vehicles, so as to minimize the time the lecture...

Measurement of natural selection on correlated characters provides valuable information on fitness surfaces, patterns of directional, stabilizing, or disruptive selection, mechanisms of fitness variation operating in nature, and possible spatial variation in selective pressures. We examined effects of seed weight, germination date, plant size, early growth, and late growth on individual fitness...

In this work we develop a visual place recognition system for omnidirectional panoramic images that makes use of their full 360 degree circumferential angle of view. The system builds on our previous variant of the sequence SLAM algorithm to include panoramic image rotation alignment for improved image similarity scoring, and bi-directional query and database sequence matching within a Hidden M...

With the continued increase of speed and capacities of computing devices and the growing needs of people for mobile computing capabilities, multihop wireless networks have gained a lot of interest from the research community. Quality of service (QoS) provisioning in these networks is an essential component that is needed to support multimedia and real-time applications. On the other hand, direc...
