We studied the effect of anterior and posterior axial crystalline lens displacement (and thereby ciliary tone) on the aqueous humor outflow facility in enucleated human eyes. After attaching a reversible footplate plunger to the anterior lens capsule with cyanoacrylate, the lens was placed in one of three positions: "neutral baseline," posterior displacement (2.5 mm), or anterior displacement (...

Static coseismic offsets >1 mm are observed up to 7800 km away from the great Sumatra-Andaman earthquake of 26 Dec. 2004 using global GPS network data. We investigate the rupture process based on far-field continuous GPS data. To reduce error in the coseismic offset estimates due to post-seismic deformation in the days following the main shock, we simultaneously fit a model of coand postseismic...

Measurements of surface displacement made using GPS, SAR interferometry, and ground-based photogrammetry were compared for a number of targets located close to the terminus of a polythermal arctic glacier. The results showed that average measurements for the winter period made using GPS and SAR interferometry agreed well at most locations. Horizontal and vertical photogrammetric measurements we...

This paper describes an embedded pedestrian navigation system composed of a self-contained sensors, the Global Positioning System (GPS) and an active Radio Frequency Identification (RFID) tag system. We use self-contained sensors (accelerometers, gyrosensors and magnetometers) to estimate relative displacement by analyzing human walking locomotion. The GPS is used outdoors to adjust errors in p...

Malaysia is witnessing a rapid growth in the vicinity of urban cities with the construction of large engineering structures (e.g. towers, factories, high-rise condominiums, wide-span bridges and highways) to meet the requirement for the nation’s economic growth, societal activities and the aspirations of its population. These manmade structures are, however, subject to deformation and structura...

This paper investigates the feasibility using continuously operating reference stations (CORS) in Victoria (termed GPSnet) for deformation monitoring and analysis. A number of critical issues associated with the suitability, geological stability, data quality of the GPS networks system, the precision and reliability of the GPSnet solution are investigated using geological information. Appropria...

For airborne surveys, direct georeferencing has become the primary source for EOPs (Exterior Orientation Parameters) determination since integrated GPS/INS (Global Positioning System/Inertial Navigation System) systems were introduced. However, there is still need for alternative indirect georeferencing since there are remote, inaccessible areas that lack a geodetic infrastructure and thus GPS/...

We tested the effect of copackaging retroviral vectors of different sizes on retroviral replication and recombination. Our results indicate little or no difference in replication or in the rate or pattern of the strand transfers leading to the formation of recombinant proviruses with size. The size difference of the vectors also allowed us to extend our previous analysis of the linkage of marke...

In a gravel pit (SE Vienna basin), metre-thick bedded successions of conglomerate and sand layers of Miocene age are exceptionally well exposed along a W-E-striking wall. The sediments are cut by numerous N-Sstriking, high-angle normal faults. The faults have a marked displacement gradient and offset marker layers of up to several metres. Using ground penetrating radar, we measured ten sections...

This paper presents a method of accurately determining the displacement of tracer particles between two images using recursive correlation. The local correlation value is iteratively arrived at through successive approximations of local displacement using increasingly smaller regions of determination. By starting with a large search area and iteratively narrowing the search restricting the sear...
