Fast and accurate relative positioning for baselines less than 20 km in length is possible using dual-frequency Global Positioning System (GPS) receivers. By measuring orthometric heights of a few GPS stations by di€erential levelling techniques, the geoid undulation can be modelled, which enables GPS to be used for orthometric height determination in a much faster and more economical way than ...

New Zealand uses 13 separate local vertical datums (LVDs) based on normal-orthometric-corrected precise geodetic levelling from 12 different tide-gauges. We describe their unification using a regional gravimetric quasigeoid model and GPS-levelling data on each LVD. A novel application of iterative quasigeoid computation is used, where the LVD offsets computed from earlier models are used to app...

The Campo de Dalias is an area with relevant seismicity associated to the active tectonic deformations of the southern boundary of the Betic Cordillera. A non-permanent GPS network was installed to monitor, for the first time, the fault- and fold-related activity. In addition, two high precision levelling profiles were measured twice over a one-year period across the Balanegra Fault, one of the...

Seven reactive dyes judiciously selected based on chemical structures and fixation mechanisms were applied at 2% of of shade on amidoximated acrylic fabrics. Amidoximated acrylic fabric has been obtained by a viable amidoximation process. The dyeability of these fabrics was evaluated with respect to the dye exhaustion, fixation, and colour strength under different conditions of temperature and ...

Two noticeable events will speed-up the development of road construction robotics the recent availability on the market of adapted localization systems, the increasingly developing utilization of computer aided design in the study of road construction projects. Currently, no links do exist between the design studies and the construction work involving digital data which could be used for progra...

HISHAM HN, HALE M & NORASIKIN AL. 2014. Equilibrium moisture content and moisture exclusion efficiency of acetylated rattan (Calamus manan). The reduced equilibrium moisture content (EMCR) and moisture exclusion efficiency (MEE) of acetylated rattan was studied in relation with age and time of acetylation. Rattans aged 10 and 13 years grown under rubber trees were reacted with acetic anhydride ...

‘Levelling UP’ has taken on considerable significance in the policy discourses of Johnson conservative government, particularly regarding English regions. However, what is meant by Levelling up been far from clear, although if it to mean anything must at least part addressing needs disadvantaged and left behind communities. Key premises this paper are that young people be considered valued memb...

— For large scale distributed storage systems, flash memories are an excellent choice because flash memories consume less power, take lesser floor space for a target throughput and provide faster access to data. In a traditional distributed filesystem, even distribution is required to ensure load-balancing, balanced space utilisation and failure tolerance. In the presence of flash memories, in ...
