background: a new microextraction method named dispersive liquid-liquid microextraction (dllme) for determination of chloroform in pool water and blood of swimmers after swimming is described. methods: this method was performed based on coupling dispersive liquid-liquid microextraction (dllme) with gas chromatog­raphy-mass spectrometry (gc-ms). methanol and trichloroethylenes were used as the d...

As is well known that sensing and measuring the weld pool surface is very important to design intelligent welding machines which is able to imitate a skilled human welder who can choose suitable welding parameters. Therefore, in this paper, we concentrate the problem of weld pool surface 3D reconstruction, which is a key issue in intelligent welding machines development. Firstly, the framework ...

We explore how active learning with Support Vector Machines works well for a non-trivial task in natural language processing. We use Japanese word segmentation as a test case. In particular, we discuss how the size of a pool affects the learning curve. It is found that in the early stage of training with a larger pool, more labeled examples are required to achieve a given level of accuracy than...

A software application called “Musical Gene Pool” is described. It was designed to evolve non-linear music from an initial random soup of sounds, which play continuously. Most evolutionary music systems to date require the user to select for musical aspects in a piecemeal fashion, whereas this system is experienced as continuous music throughout the entire process, as follows: a human listener ...

We consider a multi-pool version of the infinitely-many armed bandit problem, where a learning agent is faced with several large pools of items, and interested in finding the best item overall. At each time step the agent chooses a pool, and obtains a random item whose value is precisely revealed. The obtained values within each pool are assumed to be i.i.d., with an unknown probability distrib...

This paper discusses the signs that indicate a machine is suffering from a virtual memory constraint in 32-bit Windows. Machines configured with 2 GB or more of RAM installed are particularly vulnerable to this condition. It also discusses options to keep this from happening, including (1) changing the way 32-bit virtual address spaces are partitioned into private and shared ranges, (2) setting...

In vitro selection of functional RNAs from large random sequence pools has led to the identification of many ligand-binding and catalytic RNAs. However, the structural diversity in random pools is not well understood. Such an understanding is a prerequisite for designing sequence pools to increase the probability of finding complex functional RNA by in vitro selection techniques. Toward this go...

A random testing strategy for object-oriented software constructs test runs by repeatedly performing the following three tasks: 1) randomly select a method under test (MUT); 2) randomly select or construct target or argument objects to feed to the chosen method; 3) invoke the test case. Usually all the objects created for or returned by a MUT are stored in an object pool for reuse by future tes...

Uniform random intersection graphs have received much interest and been used in diverse applications. A uniform random intersection graph with n nodes is constructed as follows: each node selects a set of Kn different items uniformly at random from the same pool of Pn distinct items, and two nodes establish an undirected edge in between if and only if they share at least one item. For such grap...
