America ' s Great Lost Expedition

Until recently the largest and single most significant collection of Hopi Indian art lay buried amidst the dusty recesses of the Peabody Museum. The "Thomas V . Kearn Collection of Hopi Material Culture ," consisting of approximately 4,500 ethnographic objects ranging from prehistoric pots, baskets, and textile fragments to nineteenthcentury wooden tablitas and ceremonial art , was acquired thr...

Harold martin scott (1901-1991)

H. M. Scott, or Scotty to his friends, was born in 1901 in Lincoln, Nebraska. He received his B.S. degree in 1924 from Oregon State College, his M.S. in 1927 from Kansas State College, and his Ph.D. from the University of Illinois in 1938. He held faculty positions at North Dakota State College (1927–1928), Kansas State College (1928–1941), the University of Connecticut (1941–1947), and the Uni...

Factoring N=p^rq^s for Large r and s

Boneh et al. showed at Crypto 99 that moduli of the form N = pq can be factored in polynomial time when r ' log p. Their algorithm is based on Coppersmith’s technique for finding small roots of polynomial equations. In this paper we show that N = pq can also be factored in polynomial time when r or s is at least (log p); therefore we identify a new class of integers that can be efficiently fact...

نگاشت های R - s - پیوسته

کلاس جدیدی از نگاشتهای پیوسته، به نام نگاشت های R - s - پیوسته ، معرفی میشود. ارتباط میان R - s - پیوستگی با پیوستگی و انواع دیگری ازپیوستگیهای قوی که تاکنون معرفی شده اند، بررسی میشود. سپس ویژگیهای نگاشتهای R - s - پیوسته مورد مطالعه قرار میگیرد.
