Active–passive mixtures with bulk loading: a minimal active engine in one dimension

Bulk loading a Data Warehouse

This paper considers the issue of bulk loading large data sets for the UB-Tree, a multidimensional index structure. Especially in dataware housing (DW), data mining and OLAP it is necessary to have efficient bulk loading techniques, because loading occurs not continuously, but only from time to time with usually large data sets. We propose two techniques, one for initial loading, which creates ...

Simulations of transport in one dimension

Advection-dispersion equation is solved in numerically by using combinations of differential quadrature method (DQM) and various time integration techniques covering some explicit or implicit single and multi step methods. Two different initial boundary value problems modeling conservative and nonconservative transports of some substance represented by initial data are chosen as test problems. ...

Bulk Loading into Databases: a Declarative Approach

We present novel optimization techniques for bulk loading into databases. The aim of this work is to capture, understand and optimize diierent performance criteria (e.g., elapsed time, bandwidth, memory consumption) when populating a database with a large amount of data. This work applies to many applications where large amounts of data are manipulated: dataware-houses, replicated databases, et...

Energy band correction due to one dimension tension in phosphorene

Among graphene-like family, phosphorene is a typical semiconducting layered material, which can also be a superconductor in low temperature. Applying pressure or tension on phosphorene lattice results in changing the hopping terms, which change the energy bands of the material. In this research we use the tight-binding Hamiltonian, including relevant hopping terms, to calculate energy bands of ...
