Simultaneous localization and mapping (SLAM) plays an important role in fully autonomous systems when a GNSS (global navigation satellite system) is not available. Studies in both 2D indoor and 3D outdoor SLAM are based on the appearance of environments and utilize scan-matching methods to find rigid body transformation parameters between two consecutive scans. In this study, a fast and robust ...

UNLABELLED The relationship between mother and child in the context of oral health has traditionally been exposed by the scientific literature in microbiology, which lacks a broad and necessary discussion of health and illness seen as processes, both biological and social. OBJECTIVE Investigate the family social determinants associated with the caries history of children and the need for dent...

OBJECTIVE To explore the relationship between the Multiple Sclerosis Functional Composite (MSFC), which is comprised of 3 clinical dimensions (arm and hand function, leg function and ambulation, cognition), and an everyday functional skill, driving performance. DESIGN Cohort study. SETTING Medical rehabilitation research organization. PARTICIPANTS Twenty-nine individuals with documented m...

The Industrial Computed Tomography (ICT) is an advanced NDT technology to get exact internal and external structure information of the tested specimen. The nondestructive testing personnel can control the outgoing quality of workpieces by ICT image processing and data measurement. In this paper, we introduce high energy industrial CT system with accelerator X-ray source which is developed for b...

Magnetic induction tomography (MIT) is a tomographic technique utilising inductive coils and eddy currents to map the passive electromagnetic properties of an object. Eddy current methods are widely used for non-destructive testing (NDT) in inspection of metallic structures. Eddy current based NDT uses a single coil or a pair of coils to scan the samples. As an emerging NDT technique, MIT scans...

Nondestructive testing (NDT) provides safe operation to engineering components – it eliminates the risk of damage during operation, and does not require specific sample preparation. It has been widely used to detect and evaluate defects, or measure properties of different types of materials and engineering structures. Examples of NDT techniques include ultrasonic, radiography, infrared thermogr...

Eddy current testing is a kind of non-destructive testing (NDT) method based on the principle of electromagnetic induction. The probe is the key of eddy current non-destructive inspection and its design or combination of form will influence detectability. A complete set of eddy current testing system is designed for standard testing copper and defect copper. Under the same liftoff distance and ...
