To gain knowledge about the unknown state $\theta$ of nature, we perform experiments. Sufficiency of an experiment for another experiment has been introduced for the comparison of experiments. The knoledge before and after an experiment makes it possible to discuss the amount of information provided by the experiment.

의낙차수력발전소의 속도조정문제는 많은 연구대상을 갖고 있다. 이에 관계되는 문제는 수압변동에 따르는 수추작용현상(water hammering)이며 이의 시간특성의 치가 비교적 크다. 물론 속도조정문제를 위하여 단위실성정수가 수추작용의 시간특성 .theta.보다 큰 발전기를 사용하면 되나, 비용이 고가로 될 것이므로 개량된 조정기를 사용해서 해석코자 하고 있다.

In the present paper, a theorem dealing with local property of ${\mid}\;\overline{N},p_n,{\theta}_n\;{\mid}_k$ summability of factored Fourier series which generalizes a result of Mazhar [8], has been proved. Some new results have also been obtained.

In this manuscript, hybrid fixed point results for four maps using (E.A) and tangential properties in the setting of metric space are studied. Application to system of functional equations is also studied.

We determine explicit formulas for the number of representations of a positive integer n by quaternary quadratic forms with coefficients 1, 2, 5 or 10. We use a modular forms approach.

In this article, we discuss and survey the recent progress towards the Schottky problem, and make some comments on the relations between the André-Oort conjecture, Okounkov convex bodies, Coleman's conjecture, stable modular forms, Siegel-Jacobi spaces, stable Jacobi forms and the Schottky problem.
