Precision beam pointing is the key indicator for APT (acquisition, and tracking) system in space laser communication. The travels inside optical vector will be affected by an assembly error of axis reflectors. In this paper, model path coaxiality induced are established; distribution given a quantitative analysis performed. results show that magnitude assembling greatly but its susceptible to r...

There are many interesting aspects ( hardware and software ) of the Colorado Space Grant Robotics Challenge to be solved including mobility on the sand, obstacle detection and avoidance, general planning, and the use of sensors and actuators in an imperfect world. None of these aspects will lead to a robot that can complete the challenge in the absence of a radio beacon system that allows homin...

In this paper, we develop a method to check the schedulability superframe with beacon-enabled mode in ISA100.11a Wireless Industrial Networks environment. Maximum length of time slot is added in the superframe to reduce the overhead, and deadline monotonic scheduling approach is proposed to analyze the system scenario. The simulation results indicate that our proposed method required less numbe...

Abstract A path planning for mobile beacon nodes is presented based on the node localization problem of WSN. The beacon nodes define the unknown node position by using ranging method of RSSI. By analyzing defects of a static trajectory, random trajectory, the beacon nodes move to the maximum coverage of unlocated nodes. The simulation result demonstrates that this algorithm obtains good localiz...

For the localization competition, we propose to deploy an indoor localization system based on Non-Uniform Sequence Based Localization (NU-SBL) algorithm. NU-SBL algorithm works by dividing the two dimensional localization space into faces on the basis of the ranked RSS from the deployed stationary beacon nodes. The algorithm requires the scaled floor plan of the building and the location coordi...

Researchers use four moves to show how their work is important, relevant, and novel: (1) Explain the significance of the research area, (2) Describe the status quo (current state of research) in the field, (3) Identify a " gap " in that research, and (4) Fill that gap with your project. This handout offers examples to highlight possible lexical bundles used to complete each move. Here, you shou...
