PURPOSE To quantify the forces necessary to change the shape and optical power of human and monkey lenses. METHODS Cynomolgus monkey (n = 48; age: 3.8-11 years), rhesus monkey (n = 35; age: 0.7-17 years) and human (n = 20, age 8-70 years) eyes obtained postmortem, including the lens, capsule, zonules, ciliary body, and sclera were mounted in an(More)
OBJECTIVE The problem of foreign body aspiration in the community has been studied and compared with other reports. METHODS We have retrospectively studied patients who had bronchoscopy for suspected foreign bodies in the tracheobronchial tree, attending or referred to Al-Noor Specialist Hospital, Makkah over a period of 3 years from May 1996 to May 1999.(More)

The laminated composite beams are basic structural components used in a variety of engineering structures such as airplane wings, helicopter blades and turbine blades as well as many others in the aerospace, mechanical, and civil industries. An important element in the dynamic analysis of composite beams is the computation of their natural frequencies and(More)
Design concept is an important wealth-creating activity in companies and infrastructure. However, the process of designing is very complex. Besides, the information required during the conceptual stage is incomplete, imprecise, and fuzzy. Selection of proper materials for a diverse mechanism is one of the hardest tasks in the design and product improvements(More)
Multi-criteria decision making (MCDM) is one of the most well known branches of decision making and it is referring to making decision in the presence of multiple criteria. Analytic Hierarchy Process (AHP) is a common tool used to solve the MCDM problem. Since AHP has been introduced, it has been applied in numerous situations with impressive results.(More)
Laparoscopic surgery as a treatment for congenital biliary dilatation is uncommon. We herein present a series of laparoscopic surgeries for congenital biliary dilatation performed in our institution and review our experience with this approach over a long period of time. Medical records of 36 consecutive patients who underwent laparoscopic surgery for(More)
Medical image denoising is the main step in medical diagnosis, which removes the noise without affecting relevant features of the image. There are many algorithms that can be used to reduce the noise such as: threshold and the sparse representation. The K-SVD is one of the most popular sparse representation algorithms, which is depend on Orthogonal Matching(More)
