The Automated Product Delivery System (APDS) was developed to address a need in industrial manufacturing for a simple way to transfer materials between areas of a manufacturing environment. At the moment, most equipment used for such a task consist of some type of fixed system, such as conveyor belts, elevators, etc. While adequate, they are not easily adaptable to any changes in their environm...

BACKGROUND Current professional guidelines recommend a maximum hang time for reprocessed duodenoscopes of 5-14 days. We sought to study the association between hang time and risk of duodenoscope contamination. METHODS We analyzed cultures of the elevator mechanism and working channel collected in a highly standardized fashion just before duodenoscope use. Hang time was calculated as the time ...

Notwithstanding the interest in three-surface concept shown by aircraft designers, this configuration was not thoroughly investigated conjunction with adoption of two-elevator surfaces, on both canard and tail. In fact, inclusion an additional elevator produces a redundant longitudinal control which can be specifically exploited to target trim optimization. The same redundancy also employed imp...

The objective has been to develop a viable scenario for the construction, deployment and operation of a space elevator using current or near future technology. This effort has been primarily a paper study with several experimental tests of specific systems. Computer simulations, engineering designs, literature studies and inclusion of existing programs have been utilized to produce a design for...

Nowadays, most of the main companies in the vertical transport industry are researching tools capable of providing support for the design process of elevator systems. Numerous decisions have to be taken to obtain an accurate, comfortable, and high-quality service. Effectively, the optimization algorithm is a key factor in the design process, but so are the number of cars being installed, their ...

aircraft regarding to the elevator deflection angle is designed. The way how the elevator angle affects pitching motion of the aircraft is pointed out, as well as, how a pitch controller can be applied for the aircraft to reach certain pitch angle. In this digital optimal system, the elevator deflection angle and pitching angle of the plane are considered to be input and output respectively. A ...

An elevator configuration task, the VT task, is modelled within DESIRE as a design task. DESIRE is a framework within which complex reasoning tasks are modelled as compositional architectures. Compositional architectures are based on a task decomposition, acquired during task analysis. An earlier developed generic task model of design, based on a logical analysis and synthesis of task models de...

The latest elevator systems have structural differences from traditional systems, such as the use of destination calls, or multiple cars in the same hoistway. This requires the development of new elevator group control systems, which is best done by adopting modern soft-computing methods. We review some of these systems and the results of research so far, and suggest further directions of resea...

Post-installed elevator projects have grown significantly in recent years response to the problem of insufficient vertical traffic capacity existing buildings, but research on seismic performance post-installed structures has been relatively limited. This study takes a 26-story-frame shear wall structure as an example. The characteristics this before and after installation elevators were analyz...
