This thesis fills a gap in the history of mental handicap by focusing on a specific mentally handicapping condition, Down's syndrome, in Britain and America. This approach has facilitated an examination of how various scientific and social developments have actually affected a particular group of people with handicaps. The first chapter considers certain historiographical problems this research...
A (k, n) secret image sharing method shares a protected image in n shared images and the protected image can be reconstructed by k shared images. This study solves the secret image sharing problem by a geometry secret sharing strategy named the Blakley scheme. The protected image is first partitioned into non-overlapping sets of k pixels. Each set of k pixels forms a point under a k-dimensional...
background : aneuploidy is one of the main causes of congenital anomalies, mental and physical disabilities, in new-borns. the aim of this study was to determine various chromosomal aneuploidies in the first and second trimester screening of pregnant women, in iran. methods : a descriptive retrospective study was conducted on 125,170 pregnant women referred to a major referral medical diagnosti...

BACKGROUND Cerebral salt wasting syndrome (CSWS), syndrome of inappropriate antidiuretic hormone secretion (SIADH) and diabetes insipidus (DI) are frequently found in postoperative neurosurgery. PURPOSE To identify these syndromes following neurosurgery. METHOD The study included 30 patients who had been submitted to tumor resection and cerebral aneurysm clipping. Sodium levels in serum and...

This article develops an algorithm for a group of guards statically positioned in a nonconvex polygonal environment with holes. Each guard possesses a single searchlight, a ray sensor which can rotate about the guard’s position but cannot penetrate the boundary of the environment. A point is detected by a searchlight if and only if the point is on the ray at some instant. Targets are points whi...
Blakley, Blakley, Chan and Massey conjectured a lower bound on the entropy of broadcast messages in threshold schemes with disenrollment. In an effort to examine the conjecture, we identify their original scheme definition has a limitation: a coalition of participants can reconstruct all shared secrets without broadcast from the dealer, and hence render the dealer no control over disenrollment....
Blakley, Blakley, Chan and Massey conjectured a lower bound on the entropy of public broadcast in a threshold scheme with disenrollment capability. In this paper, we first show that the conjecture need not be true in general. Then we establish a tight lower bound on the entropy of public information by introducing one property to the definition of threshold schemes with disenrollment. We also p...
