Autonomous Underwater Vehicle Navigation via Sensors Maximum-Ratio Combining in Absence of Bearing Angle Data [PDF]

open access: goldJournal of Marine Science and Engineering, 2023
This paper proposes a maximum-ratio combining sensor fusion scheme for using an extended Kalman filter in the underwater vehicle positioning task by means of communication devices (buoys) providing location information using a slant-range mechanism ...

Hybrid Guidance Optimization for Multipulse Glideslope Approach with Bearing-Only Navigation [PDF]

open access: goldAerospace, 2022
This paper proposes a modified glideslope guidance method that optimizes a hybrid multiobjective of bearing-only navigation error and fuel consumption. The traditional glideslope guidance fixes uniform maneuver intervals and the initial approach velocity

Reliability and Validity of the Femorotibial Mechanical Axis Angle in Primary Total Knee Arthroplasty: Navigation versus Weight Bearing or Supine Whole Leg Radiographs

open access: diamondKnee Surgery and Related Research, 2018
Purpose To evaluate the reliability and validity of the femorotibial mechanical axis angle from radiographs in the weight bearing (WB) and supine positions compared with navigation-measured values.

No differences in clinical outcomes between fixed‐ and mobile‐bearing computer‐assisted total knee arthroplasties and no correlations between navigation data and clinical scores [PDF]

open access: hybridKnee Surgery, Sports Traumatology, Arthroscopy, 2014
PurposeThe theoretical advantages of mobile-bearing (MB) designs over the conventional fixed bearings (FBs) for total knee arthroplasty (TKA) have not been proved yet through clinical studies.

Navigation Improves the Survival Rate of Mobile-Bearing Total Knee Arthroplasty by Severe Preoperative Coronal Deformity: A Propensity Matched Case–Control Comparative Study

open access: greenThe journal of knee surgery, 2020
The primary hypothesis of this study was that the survival rate over 10 years of total knee arthroplasties (TKAs) implanted with a navigation system was superior to that of TKAs implanted with a conventional technique.

3D-printed navigation-guided FNS-CCS fixation reduces complications in young adults with comminuted femoral neck fractures: a retrospective cohort study [PDF]

open access: yesBMC Musculoskeletal Disorders
Background Young adults with comminuted femoral neck fractures face elevated risks of postoperative shortening and osteonecrosis of the femoral head (ONFH) This study evaluates a novel surgical protocol integrating the Femoral Neck System (FNS) and 3D ...

Mobile bearing shows larger rollback motion than fixed bearing in total knee arthroplasty using a medial stabilising technique with a navigation system

open access: goldJournal of Experimental Orthopaedics
Purpose This study aimed to investigate the intraoperative knee kinematics of cruciate‐retaining total knee arthroplasty with a medial stabilising technique (MST‐TKA) and compare the kinematics between mobile‐ and fixed‐bearing MST‐TKAs.

Comparison of Mechanical Axis and Dynamic Range Assessed with Weight Bearing Radiographs and Navigation System in Closed Wedge High Tibial Osteotomy

open access: diamondKnee Surgery and Related Research, 2017
Purpose To compare navigation and weight bearing radiographic measurements of mechanical axis (MA) before and after closed wedge high tibial osteotomy (HTO) and to evaluate post-osteotomy changes in MA assessed during application of external varus or ...
