Ocean-going vessels usually sail at a constant speed in open sea.Rule 8 of the International Regulations for Preventing Collisions at Sea (COLREGs) recommends alteration of course as the single most effective way to avoid collisions.This makes the study of constant speed collision avoidance (CSCA) critical for the development of automatic navigatio
In birds with facultative brood reduction, survival of the junior chick is thought to be regulated primarily by food availability.In black-legged kittiwakes (Rissa tridactyla) where parents and chicks are provided with unlimited access to supplemental food during the breeding season, brood reduction still occurs and varies interannually.Survival of
The geomagnetic total force observations along the navigation route from Japan to the Antarctic Ocean via Singapore and Cape Town were carried out using the Proton Precession Magnetometer which was used in the second (1957-58) and the third (1958-59) expeditions for the same purpose.We got nearly the same results at the Indian Ocean as on former ob
Enzymatic browning is a serious quality deterioration of fresh-cut fruits and vegetables.Recently, consumers and fruit and vegetable industrial processors have demanded the use of natural antibrowning agents to replace the use of chemicals.Mango (Mangifera indica cv.Chok Anan) peel was prepared in the form of mango peel liquid nitrogen powder.This
A microwave power limiter with an H-type slot structure is proposed as a waveguide structure that blocks high-power microwaves through plasma discharge.At an operating frequency of 5.75 GHz, the electric field is concentrated in the discharging electrode gap; when high power is applied, the plasma limiter discharges, and low power is transmitted.By
