There has been increasing interest over the last few years in the use of radar interferometry for land subsidence evaluation/monitoring. InSAR time series algorithms such as PSI and small baseline methods offer the possibility to measure ground displacements to a degree of accuracy comparable to traditional geodetic technique such as leveling. This preliminary work reveals the potential of time...

Peatland surface motion is highly diagnostic of peatland condition. Interferometric Synthetic Aperture Radar (InSAR) can measure this at the landscape scale but requires ground validation. This necessitates upscaling from point to areal measures (80 × 90 m) hampered by a lack data regarding spatial variability peat characteristics. Using nested precise leveling approach within two areas upland ...

In this work, the thermal stabilities of a series of polyethylene glycols (PEG 4000, 6000 and 10000) were investigated after compositing with different kinds of inorganic salts, such as ammonium molybdate tetrahydrate (AMT), NH4VO3, (NH4)2SO4, NH4NO3, Na2SO4, Na2MoO4. It was first observed that all the ammonium salts exerted leveling effects for the thermal stabilities of the PEGs. In other wor...

Phase Change Memory (PCM) may become a viable alternative for the design of main memory systems in the next few years. However PCM suffers from limited write endurance. Therefore future adoption of PCM as a technology for main memory will depend on the availability of practical solutions for wear leveling that avoids uneven usage especially in the presence of potentially malicious users. First ...

studying active faults behavior for earthquake prediction and recognition is a concentrated subject in earth science. precise measurements of earthsurface deformation by geodetic observation provide a good reference for studying different geodynamic phenomena.  applying geodetic measurements in postseismic and interseismic intervals is an important tool for estimating strain accumulation and rh...

resource leveling and allocation are two basic categories for project management. the objective of resource allocation is to schedule activities so that a particular resource does not exceed a specific limit in any given project time period, while holding the project duration to a minimum. the resource leveling problem arises when there are sufficient resources available and it is necessary to ...

The article is devoted to the numerical simulation and experimental verification of a vehicle’s response kinematic excitation caused by driving along an asphalt road. source was road unevenness, which mapped geodetic methods. Vertical unevenness measured in 0.25 m increments two longitudinal profiles spaced meters apart with precise leveling realized digital levels. A space multi-body computati...
