Workstations typically depend on remote servers accessed over a network for such services as mail, printing, storing files, booting, and time. The availability of these remote services has a major impact on the usability of the workstation. Availability can be increased by replicating the servers. In the Echo distributed file system at DEC SRC, two different replication techniques are employed,...

Humans possess manual dexterity, motor skills, and other physical abilities that rely on feedback provided by the somatosensory system. Herein, a method is reported for creating soft somatosensitive actuators (SSAs) via embedded 3D printing, which are innervated with multiple conductive features that simultaneously enable haptic, proprioceptive, and thermoceptive sensing. This novel manufacturi...

The GOLEM project is an attempt to extend evolutionary techniques into the physical world by evolving diverse electro-mechanical machines (robots) that can be fabricated automatically. In this work we go beyond evolution of hardware controllers and demonstrate for the first time a path that allows transfer of virtual diversity of morphology into reality. Our approach is based on the use of only...

A set of modular components is presented for use in reconfigurable robotic construction systems. The set includes passive and active components. The passive components can be formed into static structures and adaptable grids carrying electrical power and signals. Passive and active components canbe combined into general purpose mobile manipulators which are able to augment and reconfigure the g...

The main objective of this research study is to optimize the printing parameters that can be used in FDM (fusion deposition modeling) production method obtain lowest time and best parameter PLA (polylactic acid) filament with tensile test. machines such as extruder temperature, bed layer height, speed, travel infill, shell count taken into account for optimization. In addition, specimens from A...

3D printing is a method of manufacturing in which materials, such as plastic or metal, are deposited onto one another in layers to produce a three dimensional object, such as a pair of eye glasses or other 3D objects. This process contrasts with traditional ink-based printers which produce a two dimensional object (ink on paper). To date, 3D printing has primarily been used in engineering to cr...

Patent application numbers grow exponentially in many industries, a phenomenon that has been linked to high fragmentation of patent ownership. Contradicting these findings and theoretical arguments, we show that such fragmentation is not a precondition for sudden and strong increases in patenting. We describe and analyze a patent portfolio race in an industry with highly concentrated patent own...

3D printing has now been recognized as a very practical technique to create 3D structures with milli-/micron-scale resolution. In tissue engineering, particularly, people utilize 3D printing technique to integrate biodegradable polymers to tissue scaffolds. Hydrogel is highly potential material that provides aqua environment and enables nutrition and oxygen transportation, all of which are requ...

DECprint Printing Services software controls a variety of printer features for a wide range of printers. It supports several different page description languages, handles multiple media simultaneously, and uses different I/O interconnections and communication protocols. Operating within the VMS printing environment, it implements a large number of user-specified options to the PRINT command. DE...
