The expandable network disk
… presents a virtual disk cluster called END, the Expandable Network Disk. END aggregates storage on a cluster of servers into a single virtual disk. END's main goals are to offer good performance during normal operation, and efficiently handle changes in the cluster membership. END achieves these …

Evolving building system for expandable housing by means of corrugated metal sheets
Large housing programs in developing countries built out of permanent materials are likely to be too costly for low-income people. Such housing would have to be subsidized or allocated to middle-income groups. For this reason, some governments provide sites and services that allow low-income …

Performance evaluations of a parallel and expandable database computer -- the Multi-Backend Database computer
This study is the actual application of a performance evaluation technique known as benchmarking to an experimental database management system (DBMS). The specific DBMS evaluated is the Multi-Backend Database System (MBDS) which is a software multiple-backend database system. The unconventional …

The development of a remotely expandable anastomosis device for use in paediatric cardiothoracic surgery
Congenital Heart Disease (CHD) is one of the main causes of infant mortality in the UK and United States. In 2011, 47% of infants born with CHD in the UK did not survive to their first birthday. Often forms of CHD require the implantation of conduits (tubes) to redirect the blood flow around the …

Early prototyping and testing of a model of an expandable heart valve apparatus for paediatric deployment
… Unlike traditional prosthetic heart valves, the expandable valves can be enlarged while the patient grows. Such solution potentially allows avoiding the repeated valve replacement procedures that would be required when traditional valve is implanted. The aim of this study was to design nine …

Effect of assertion headings and expandable examples in online engineering textbooks on student performance and satisfaction
… course. In this thesis, we study the effect of expandable worked examples and assertive headings in online instructional texts on students' learning and affective responses. In addition, we explore whether hand-drawn figures have any effect on student satisfaction and self-efficacy. Students …

THE ART AND SCIENCE OF TRANSFORMABLE ARCHITECTURE: Geometry Theory for 2 Bar Scissor-Hinged and Expandable Origami-Scissor Hinged Deployable Structures
Deployable structures can transform and/or expand and contract due to their geometrical, material and mechanical properties. This technology enables an architecture that can be transportable, mobile, adaptable, rapidly built, reusable and that makes efficient use of space and materials and …

Modified Organoclay Containing Chelating Ligand for Adsorption of Heavy Metals in Solution.
… and kaolin were chosen as typical examples of expandable and non-expandable clays, correspondingly. Modifications with silica and ferric oxide were targeted on development of mesoporous structure. Laboratory tests of the organoclay efficiency for purification of wastewater were conducted with …

The interaction of clay minerals with distilled water and saline solutions at elevated temperatures
… The transformation of montmorillonite to a less expandable phase was greatly retarded in solutions having a low K/Ca, Mg or Na ratio. Magnesium and calcium rich solutions were more effective in retarding the reaction rate than sodium rich solutions. The size of the ratio required to be effective …

A waypoint-driven gradient descent solution for a parallel robot
… the robot is built from a sequence of expandable segments that can each extend and tilt. The current path planning algorithm computes arm motion by solving a series of inverse kinematic relations for each segment. This requires a user input of a three-dimensional coordinate to a …
