Dynamic datums, which account for crustal dynamics, are widely used in Australia and New Zealand, although in many cases users may not be aware that they are using such a datum. The most widely-used global dynamic datums in Australia and New Zealand are the International Terrestrial Reference Frame (ITRF) and the World Geodetic System 1984 (WGS84). The use of WGS84 presents particular challenge...

Let G be a complex reductive group. We study the problem of associating Dixmier algebras to nilpotent (co)adjoint orbits of G, or, more generally, to orbit data for G. If g = 0 + n + in is a triangular decomposition of g and 0 is a nilpotent orbit, we consider the irreducible components of 0 n n, which are Lagrangian subvarieties of 0. The main idea is to construct, starting with certain "good"...

Many applications of wireless sensor network require precise knowledge of the locations of nodes. Conventional sparse wireless sensor network, which is formed by a restricted number of nodes, has two drawbacks, i.e., low connective ratio and hop count limited, which probably cause the network link failure and/or low locating performance. To improve the relative position precision and reliabilit...

One may employ Data Envelopment Analysis (DEA) to discriminate decision-making units (DMUs) into efficient and inefficient ones base upon the multiple inputs and output performance indices. In this paper we consider that there is a centralized decision maker (DM) who ‘owns’ or ‘supervises’ all the DMUs. In such intraorganizational scenario the DM has an interest in discriminating the efficient ...

Measured vertical gravity gradients usually quite differ from the normal value of 0.3086 mGal/m (1mGal = 10ms). Generally the changing of vertical gradient is rather big, up to a few 10 cm height above the ground and can be taken into consideration as a second order function. Over 40 m height the changing is linear and over 500 m height the changing is very small, the measured value of vertical...

Using tape or optical devices for scale-out storage is one option for storing a vast amount of data. However, it is impossible or almost impossible to rewrite data with such devices. Thus, scale-out storage using such devices cannot use standard data-distribution algorithms because they rewrite data for moving between servers constituting the scale-out storage when the server configuration is c...

Scalable shared-memory multiprocessors are often slowed down by long-latency memory accesses. One way to cope with this problem is to use data forwarding to overlap memory accesses with computation. With data forwarding, when a processor produces a datum, in addition to updating its cache, it sends a copy of the datum to the caches of the processors that the compiler identified as consumers of ...

— Singapore’s shores have been extensively modifi ed to meet the rising demands of economic and recreational activities, and seawalls are a resultant ubiquitous feature of the island state’s coastline. In spite of the harsh environmental conditions, seawalls in Singapore are known to harbour rich intertidal communities. This study surveyed the hard coral assemblages at zones immediately above a...

We express the cohomology of the basic Newton stratum of some unitary Shimura varieties associated to division algebras in terms of automorphic representations of the group in the Shimura datum. 2010 Mathematics Subject Classification: Primary 11G18 ; Secondary 11F70, 11F72.

Under some regularity assumptions on the boundary datum u (assumptions automatically satisfied in the classical case when the growth of the integrand is bounded by a+ b‖ξ‖), we prove the validity of the Euler Lagrange equation for the functional
