The current practices used in tube drainage design often lead to unsatisfactory results : from the point of view of the system's hydraulic performance, or from the point of view of high cost of the system in relation to the actual economic benefits derived from it. It is proposed therefore, that the design of tube drainage systems should be based on a synthesis of experimental field results, an...

During the design of storm drainage system, many decisions are involved on the basis of rules of thumb, heuristics, judgment, code of practice and previous experience of the designer. It is a suitable application field for application of the recent artificial intelligence technology. This paper presents the knowledge representation of the design of storm drainage system in a prototype knowledge...

Total knee arthroplasty (TKA) is associated with significant postoperative blood loss for which blood transfusion might be necessary. The role of wound drainage is controversial. The use of drainage was believed to be effective in decreasing hematoma formation (Drinkwater and Neil 1995; Holt et al. 1997; Martin et al. 2004), which has been theoretically thought to decrease postoperative pain, s...

This article aims to elucidate the classification of and optimal treatment for pancreatic pseudocysts. Various approaches, including endoscopic drainage, percutaneous drainage, and open surgery, have been employed for the management of pancreatic pseudocysts. However, no scientific classification of pancreatic pseudocysts has been devised, which could assist in the selection of optimal therapy....

A distributed suction i1igh-lift boundary layer control system fitted to a standard liaison L-19 aircraft incre~sed the aircraft c 1 max to 5.74 and decreased the take-off and landing distance over a 50-foot obstacle by 38 percent and 29 percent, respectively, with no increase in available power. The modified aircraft demonstrated acceptable stability, control, and handling characteristics in a...

In vivo, tissues are drained of excess fluid and macromolecules by the lymphatic vascular system. How to engineer artificial lymphatics that can provide equivalent drainage in biomaterials remains an open question. This study elucidates design principles for engineered lymphatics, by comparing the rates of removal of fluid and solute through type I collagen gels that contain lymphatic vessels o...

A major emphasis in geomorphology over the past several decades has been on the development of quantitative physiographic methods to describe the evolution and behavior of surface drainage networks. The quantitative analysis of morphometric parameters is found to be of immense utility in river basin evaluation. The influence of drainage morphometry is very significant in understanding the landf...

The urban drainage system is co-regulated by various governmental departments, who adopt different standards in designing the system, an attempt not conducive to prevention of water logging. This study took Zhongshan and Zhuhai as subjects, proposed Copula-based design a calculated most practical solution drainage, waterlogging rainfall based on Kendall’s Return Period, providing references for...

The cost of medical care has risen rapidly in recent years due largely to the introduction of new and more expensive technology and the need for skilled personnel to manage the devices. Even the lowly catheter and its drainage bag considerably influence medical care costs. Despite their low unit cost, the overall expenditure by hospitals for indwelling urinary catheter systems is considerable. ...
