We investigate universal bounds on spherical codes and spherical designs that could be obtained using Delsarte’s linear programming methods. We give a lower estimate for the LP upper bound on codes, and an upper estimate for the LP lower bound on designs. Specifically, when the distance of the code is fixed and the dimension goes to infinity, the LP upper bound on codes is at least as large as ...

Though it is vital to estimate infiltration as one of the key factors in effective management of water resources, only few studies have been carried out either to determine the infiltration or to compare the performance of infiltration models for coarse textured soils. Thus, the present study was conducted to accomplish two objectives. First to estimate the Horton’s infiltration model parameter...

To identify factors that influence changes in the activities of daily living (ADL) assessed by a standardized scoring system, ADL-20, and factors affecting the self-estimate of the changes in ADL, we conducted a 1-yr follow-up study of 1,163 outpatients aged 50 yr or older. The follow-up rate was 83.1%. A decrease in the ADL score was associated with advancing age and a lower prescription rate ...
