Collaborative Map Matching in Nav2Nav [PDF]

Proceedings of the 7th International Conference on Collaborative Computing: Networking, Applications and Worksharing, 2011
Although in-car navigation systems are becoming commonplace, cars travelling in urban canyon areas still suffer from poor positional accuracy and limited visibility of GPS satellites due to signal blockage. As a result, map matching accuracy and navigation performance may not reach the required level for many applications.

Research on Multi-sensor Fusion Localization for Autonomous-rail Rapid Tram

Kongzhi Yu Xinxi Jishu, 2022
Traditional positioning methods, such as GNSS (global navigation satellite system) and location base service, have large positioning error when applied in complex traffic scenarios such as like tunnels buildings and viaducts.

Map-Matching Using Shortest Paths [PDF]

ACM Transactions on Spatial Algorithms and Systems, 2018
We consider several variants of the map-matching problem, which seeks to find a path Q in graph G that has the smallest distance to a given trajectory P (which is likely not to be exactly on the graph). In a typical application setting,

Map-matching Algorithm for Large Databases [PDF]

Journal of Navigation, 2015
This article proposes a batch-mode algorithm to handle the large databases generated from experimentations using probe vehicles. This algorithm can locate raw Global Positioning System (GPS) positions on a map, but can also be used to correct map-matching errors introduced by real time map-matching algorithms.

Concurrent and robust topological map matching [PDF]

Proceedings of the 20th International Conference on Advances in Geographic Information Systems, 2012
Offline map matching is a process of associating a sequence of GPS location readings measured with a device held by a traveling user, to the real-world roads that were presumably traveled by the user. The main goals in map matching are (1) to provide an association which is as accurate as possible with respect to actual traveled roads, and (2) to ...

Geomagnetic/inertial navigation integrated matching navigation method

Heliyon, 2022
The accuracy of an a priori geomagnetic reference map is a significant constraint on the geomagnetic matching navigation method. Especially when the aircraft enters an unknown environment, it is impossible to accomplish the navigation task using ...

Map Matching for Urban High-Sampling-Frequency GPS Trajectories

ISPRS International Journal of Geo-Information, 2020
As a fundamental component of trajectory processing and analysis, trajectory map-matching can be used for urban traffic management and tourism route planning, among other applications.

Personalized Zebrafish Models for Fusion‐Positive Pediatric Sarcomas

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Clinical sequencing efforts have revolutionized our approaches to categorizing pediatric cancers in real time. This has dramatically improved our ability to profile pediatric tumors, identify actionable vulnerabilities, and influence clinical care.

The Role of “Adult‐Onset” Cancer Predisposition Genes in Pediatric Cancer: A Comprehensive Review

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Current literature estimates that 10% of pediatric cancers are caused by pathogenic or likely pathogenic (P/LP) germline variants in cancer predisposition genes (CPGs). Variants in CPGs thought to increase cancer risk exclusively during adulthood are referred to as “adult‐onset” CPGs (aoCPGs).

Health Literacy, Self‐Efficacy and Knowledge of Sickle Cell Disease Among Caregivers

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Sickle cell disease (SCD) is a hereditary blood disorder in which abnormal haemoglobin leads to severe anaemia, painful crises and organ failure. Caregivers’ health literacy (HL) – their ability to assess, understand and apply information, and interact with healthcare professionals – is crucial for managing children with SCD, yet ...
