False star detection and isolation during star tracking based on improved chi-square tests.

The Review of scientific instruments

Zhang H, Niu Y, Lu J, Yang Y, Su G.
PMID: 28863708
Rev Sci Instrum. 2017 Aug;88(8):085004. doi: 10.1063/1.4998986.

The star sensor is a precise attitude measurement device for a spacecraft. Star tracking is the main and key working mode for a star sensor. However, during star tracking, false stars become an inevitable interference for star sensor applications,...

An Improved Fast Self-Calibration Method for Hybrid Inertial Navigation System under Stationary Condition.

Sensors (Basel, Switzerland)

Liu B, Wei S, Su G, Wang J, Lu J.
PMID: 29695041
Sensors (Basel). 2018 Apr 24;18(5). doi: 10.3390/s18051303.

The navigation accuracy of the inertial navigation system (INS) can be greatly improved when the inertial measurement unit (IMU) is effectively calibrated and compensated, such as gyro drifts and accelerometer biases. To reduce the requirement for turntable precision in...

Surgical management of a massive congenital hemangioma of the tongue in an infant: A rare case report.

Clinical case reports

Sarna K, Kamau M, Guthua S.
PMID: 34631090
Clin Case Rep. 2021 Oct 06;9(10):e04909. doi: 10.1002/ccr3.4909. eCollection 2021 Oct.

Hemangiomas of the tongue may reach a massive size resulting in functional compromise. Surgical resection, despite the risk of hemorrhage, may be the only option if conservative measures such embolization are futile in reducing its size.

Hydrocephalus is widely known as "hydrocephaly" or "water in the brain," a building up of abnormal cerebrospinal fluid in the brain ventricles. Due to this abnormality, the size of the head becomes larger and increases the pressure in the...

An innovative approach in the management of alveolar clefts with bone graft harvest from maxillary tuberosity and mandibular wisdom molar odontectomy sites: A case report.

Clinical case reports

Guthua S, Ng'ang'a PM, Sarna K, Kamau M.
