This paper presents a survey using parametric design investigation of composite and homogenous cylindrical pressure vessels with hemispherical ends (also known as 'Heads' or 'Cups'). Two main kinds of composite and homogenous cylinders geometry were modeled and examined: thin and thick cylinders. Stress-strain relationships of the cylinders are derived as a result of their model equation solution. Also, reinforced wrapping method effect on thin cylinder strength was presented and examined. In addition, compound cylinder theory was discussed and main results were presented. Moreover, thick walled composite cylinders in polar coordinates theory has been developed and displayed. Filament winding methods of composed cylinder were discussed together with analytic modeling and numerical examination. Finally, failure criteria of composed and homogenous cylinders were presented and discussed.

Supportive Care in Cancer | Year: 2013
The Mucositis Study Group of the Multinational Association of Supportive Care in Cancer/International Society of Oral Oncology (MASCC/ISOO) recently conducted a systematic review to update the MASCC/ISOO clinical practice guidelines for oral and gastrointestinal mucositis. Here, we discuss the details of some considerations underlying the process used. © 2012 Springer-Verlag.

In this paper, several numerical analysis methods were performed for solving Kuiken model of boundary layer flow model development due to a moving surface ('sheet'). This model obeys to general stretching law and was presented by Kuiken in 1981. The numerical simulation methods which were used are the shooting method and finite difference method (FDM). Creating the final simulation model involved a calibration step. It was found that the shooting method does not describe properly the fluid physics as compared to finite difference method (FDM). Additionally, comparison between numerical and suggested approximate solutions was done while qualitative compatibility was found between solutions. Kuiken solution branch was found to be fully coincided with current FDM solution forκ= 1/3. Finally, comparison between ADM (Adomian Decomposition Method) and FDM has been done, while appropriate match was found between solutions. Quantitatively, all presented solutions have the same order of magnitude; nevertheless, inaccuracy between all kinds of solutions does exist.

A six-degree-of-freedom simulation of helicopter roll-on takeoff is described. The simulation incorporates helicopter and landing gear dynamic models, as well as a simplified human pilot model, which is capable of performing the takeoff process in various ambient and runway conditions and for different helicopter configurations. This simulation is used to evaluate roll-on takeoff distances and carry out a simplified preliminary optimization to define takeoff techniques that reduce the roll-on takeoff distances. © 2011 The American Helicopter Society.

RIDGECREST, CA--(Marketwired - October 31, 2015) - Ridgecrest dentist Dr. Josef Mamaliger is reminding patients to schedule their second biannual dental visit before the end of the year. Dr. Mamaliger said the end of the year is typically the busiest time of the year for his dental office, The Dentist House. With the holidays quickly approaching, Dr. Mamaliger is advising patients to schedule their visits as soon as possible to make sure they can be seen before Dec. 31. "Not many of us are considering the end of the year in October, but in a dental office, this is our busiest time," Dr. Mamaliger said. "Planning ahead gives us time to get everyone in, with a comfortable amount of time to finish their work. When we start approaching the holidays, our days get filled up and our patients' free time starts to get smaller and smaller." Many patients with dental insurance have an annual allocation that does not carry over to the next year. Dr. Mamaliger said patients with remaining insurance money may have untreated dental issues. Dr. Mamaliger sends out end-of-the-year letters to better inform patients who need to have dental treatment completed before the first of the year. The Dentist House also will be giving away a flat-screen TV as part of a patient drawing. "We want to inform patients who have outstanding dental issues so they can use their insurance benefits by the end of the year," Dr. Mamaliger said. "I hate to see patients lose their dental insurance dollars after having paid into the plan for the whole year." Dr. Mamaliger offers crowns, bridges, teeth-whitening treatments, prepless veneers and durable dental implants. Dental implants are used to replace individual missing teeth or to replace entire arches of teeth. Dental implants give patients about 90 percent of the chewing force they had with their natural teeth. Dr. Mamaliger uses dental implants to replace individual missing teeth or stabilize dentures. Dental implants have become popular options for patients with removable dentures because the implants stabilize oral devices and prevent any future jawbone deterioration. In addition to life-changing implant dentistry, Dr. Mamaliger provides prepless veneers that can transform a patient's smile instantly. No-prep veneers are unique because they do not require any drilling or removal of tooth enamel. To place the veneers, Dr. Mamaliger simply bonds the composite veneer over the tooth without any discomfort to the patient. Dr. Mamaliger was born in Russia and immigrated to Israel as a child. He earned his dental degree in Israel and then served in the Israeli Air Force for five years. Dr. Mamaliger trained with some of the best specialists in Israel before moving to the United States, where he completed his boards in 1990. He started his Ridgecrest dental office in 2007. The Dentist House uses the latest technology like a CT cone beam scanner to diagnose and treat its patients, from preventive dentistry to planning dental implants and diagnosing sleep apnea. Dr. Mamaliger offers a five-year warranty on all of his work.
