We conducted a lung cancer risk assessment for internal exposure to naturally occurring 222Rn gas both indoor and outdoor. A series of equations were used to estimate Rn concentrations indoor and outdoor and the associated lung cancer risk in some coastal regions in Egypt. The mean 222Rn concentrations were 42.98 (SD 33.12) Bq/m3 and 8.63 (SD 6.16) Bq/m3 indoor and outdoor respectively. The mea...

1. the failure of the algorithm in [AMR] and [Morelli1] for the strong factorization pointed out by Kalle Karu, 2. the statement of a refined weak factorization theorem for toroidal birational morphisms in [AMR], in the form utilized in [AKMR] for the proof of the weak factorization theorem for general birationla maps, avoiding the use of the above mentioned algorithm for the strong factorizati...

This paper examines a kernel implementation lightweight process mechanism built for the Mach operating system. The pros and cons of such a mechanism are discussed along with the problems encountered during its implementation. This research was sponsored by the Defense Avanced Research Projects Agency, Department of Defense, ARPA Order 4976, Amendment 20, monitored by the Airforce Avionics Labor...

D uring the early years of Mach, anyone who talked to Rick Rashid soon encountered two ideas that excited him. One was the idea that operating systems had grown too large and complex, and that the time had come to simplify and shrink. The second was the idea that different operating systems offered the same core functionality XQGHUQHDWK D ORW RI VXSHUÀFLDO GLYHUVLW\ DQG LW VKRXOG WKHUHIRUH EH S...

High definition video is becoming popular day by day due to desire for superior level quality and high resolution video. The upcoming High Efficiency Video Coding (HEVC) standard is designed to serve diverse range of applications like HDTV, video conferencing, fast internet streaming and videophone. This paper describes the performance analysis of HEVC with H.264/AVC video coding standard. Vari...
