Behavioral Considerations in Developing Web Information Systems: User-centered Design Agenda

The current paper explores designing a web information retrieval system regarding the searching behavior of users in real and everyday life. Designing an information system that is closely linked to human behavior is equally important for providers and the end users.  From an Information Science point of view, four approaches in designing information retrieval systems were identified as system-...

Optimum Design of Hydraulic Excavator

Excavators are heavy construction equipment consisting of a boom, dipper (or stick), bucket and cab on a rotating platform known as the "house". In this paper the hydraulic shovel excavator is analyzed through the D-H method. The shovel working device with the bucket capacity of 36m3 is optimized. The determination of the objective function, variables and constraints are described in ...

Design Considerations for Mask Projection Microstereolithography Systems

Mask projection microstereolithography (MPμSL) uses a dynamic mask and focusing optics to digitally pattern UV light and selectively cure entire layers of photopolymer resin. These systems have been shown to be capable of creating parts with features smaller than 10μm. In this paper, the authors analyze existing MPμSL systems using functional decomposition. Within the context of a morphological...
