Operational ocean observing system (OOOS) can meet the needs of marine disaster prevention and reduction, safeguard socio-economic development in coastal zones, and promote marine resource exploitation. As a solid foundation for the establishment of the OOOS, operational ocean observing equipment (OOOE) is attached great significance across the world. Three kinds of OOOEs in China are introduced and...
The problems of reliable signal transmission for condition monitoring of power equipment in the energy sector during the technical diagnostics are considered. The principles of the combined coding to ensure a high level of reliability of the systems of technical diagnostics are suggested. The technique for calculating the reliability level for the information signals is represented n this paper.
A Body Area Network (BAN) is a radio standard for wireless connectivity of wearable and implantable sensors located inside or in close proximity to the human body. Medical and some other applications impose stringent constraints on battery powered BAN reliability, quality of service, and power consumption. However, lack of coordination among multiple colocated BANs in the current BAN standard may...
Recently, there are many improvements in Internet of Things (IOT). Through the recombination and optimization, the real-world devices can provide their functionality as web services in IOT. However, it is very difficult to cost-effectively access to the Internet of Things due to the environmental changes. In this paper, firstly, a Petri net-based model for service composition in IOT is proposed, which...
Safety-Critical systems, as used in the automotive, avionics, or aerospace domains, are becoming increasingly software-reliant to the extent that the system cannot function without the software. On one hand the software system provides an integrated set of functionality to operate the system and manage failure and unsafe conditions. Current best safety engineering practices, such as DO178B/C or SAE...
Multiple sclerosis (MS) is a progressive neurological disorder affecting between 2 and 2.5 million people globally. Tests of mobility form part of clinical assessments of MS. Quantitative assessment of mobility using inertial sensors has the potential to provide objective, longitudinal monitoring of disease progression in patients with MS. The mobility of 21 patients (aged 25–59 years, 8 M, 13 F),...
In order to realize the autonomous location and attitude estimation for speedy UAV, this paper designs an improved Iterative Closest Points (ICP) algorithm for fixed-wing UAV with a laser range finder mounted onboard. This improved ICP adopts a K-d tree and AK-d tree mixed closest point searching strategy to enhance its rapidity, and an automatic trim approach to drop out outlier points to improve...
This paper introduces the characterization of the measurement uncertainty of large wafer probing in the WR-1.5 (500 GHz – 750 GHz) band. A micromachined WR-1.5 probe with integrated strain sensor is used to measure calibration standard sets at different locations on a 2-inch wafer. Measurement results of the strain sensor assisted WR-1.5 probe using 20 mN contract force are presented. As a comparison,...
In this paper a new algorithm for multi-targets tracking for roadway environment is proposed. This new approach is based on two parallel tracking stages. Its objective is to improve associations between targets and tracks by avoiding wrong associations which can cause errors on track's path determination. Another interesting point of the proposed approach lies in the fact that the two trackings stages...
High-performance industrial control systems with tens to hundreds of sensors and actuators use wired connections between all of their components because they require low-latency, high-reliability links to maintain stability; however, the wires cause many mechanical problems that moving to wireless links would solve. No existing or proposed wireless system can achieve the latency and reliability required...
In complex automated equipment, mechatronic and robotised systems, maintenance and corresponding diagnostics have extreme significance, because failure may cause considerable damages to the manufacturer. In the lecture we will deal with maintenance of robotised systems. First we will describe properties, introduction of maintenance demand of these technical systems. We will discover properties of...
