The relationship of soil-transmitted nematode infections to the availability of latrines was studied among 1,614 children 3-12 years of age living on plantations in Sri Lanka. The majority (89.7%) of the children had at least one type of soil-transmitted nematode. There was a significantly lower mean count of hookworm eggs for children coming from(More)
OBJECTIVE To compare the efficacy of a single dose mebendazole 500 mg from the original manufacturer and a formulation locally produced by State Pharmaceuticals Manufacturing Corporation of Sri Lanka and albendazole 400 mg in mass treatment of soil-transmitted nematode infections. DESIGN Randomised trial. SETTING Government owned plantations in(More)
Identification of moving objects in the vicinity of a mobile robot is important for safe navigation. This paper presents a robust technique for detecting moving objects using a laser ranger mounted on a mobile robot. The proposed method uses two consecutive laser range scans to detect the moving objects in the environment. After the initial alignment of the(More)
OBJECTIVE To determine the prevalence of soil-transmitted nematode infections among children and to assess the magnitude of nematode infections among women in the reproductive age group. DESIGN Cross-sectional study. SETTING 14 government owned plantations in the up-country and low-country regions of Sri Lanka. SUBJECTS 1614 children 3 to 12 years of(More)
This paper describes a landmark position measurement system using an integrated laser-camera sensor. Laser range finder can be used to detect landmarks that are direction invariant in the laser data such as protruding edges in walls, edges of tables, chairs. When such features are unavailable the processes that depend on landmarks such as navigation and(More)
Detection of moving objects around a mobile robot is important for safe navigation. This paper presents a robust technique for detecting moving objects using a laser ranger mounted on a mobile robot. After the initial alignment of the two consecutive laser scans, each laser reading is segmented and classified according to object type, stationary,(More)
