Detection of hepatitis B virus genotypes in a group of hepatitis B virus-infected patients in central and northern Sri Lanka.

Hepatitis B infection causes a spectrum of clinical diseases varying from asymptomatic infection to severe or fulminant acute hepatitis, chronic liver disease, cirrhosis and hepatocellular carcinoma. Hepatitis B virus (HBV) genotypes appear to influence transmission dynamics, clinical outcomes and responses to antiviral therapy. However, hepatitis B genotyping has been poorly investigated in Sri Lanka.

Vision-based dirt distribution mapping using deep learning.

Cleaning is a fundamental routine task in human life that is now handed over to leading-edge technologies such as robotics and artificial intelligence. Various floor-cleaning robots have been developed with different cleaning functionalities, such as vacuuming and scrubbing. However, failures can occur when a robot tries to clean an incompatible dirt type.

A Novel Path Planning Strategy for a Cleaning Audit Robot Using Geometrical Features and Swarm Algorithms.

Robot-aided cleaning auditing is pioneering research that uses autonomous robots to assess a region's cleanliness level by analyzing the dirt samples collected from various locations. Since the dirt sample gathering process is more challenging, adapting a coverage planning strategy from a similar domain for cleaning is non-viable. Alternatively, a path planning approach to gathering dirt samples selectively at locations with a high likelihood of dirt accumulation is more feasible.

Application of an adapted FMEA framework for robot-inclusivity of built environments.

Mobile robots are deployed in the built environment at increasing rates. However, lack of considerations for a robot-inclusive planning has led to physical spaces that would potentially pose hazards to robots, and contribute to an overall productivity decline for mobile service robots. This research proposes the use of an adapted Failure Mode and Effects Analysis (FMEA) as a structured tool to evaluate a building's level of robot-inclusivity and safety for service robot deployments.
