Abstract: This article it has become
obvious nowadays that there is a strong need for automating industrial processes.
The automation of various processes has now passed the phase defined by a
standalone, isolated operation of various devices, without the actual possibility
of centralizing the parameters that defined the monitored processes. Managers
begin to feel the need for integrating miscellaneous production parameters
within economic applications like ERPs, in order to get real time production
costs. Our proposal, outlined in this article, aims to help to cut down implementation
costs for automation systems. Thus, time and money are spared when implementing
new solutions. Total costs are also minimized, including personnel training,
and the time needed for the implementation and integration of the solution
is also reduced.
KhaoStripper
cuts down costs in the following three ways:
-
no programming or scripting is required, so personnel training costs are dramatically
decreased;
-
linking all equipment together in a centralized system will reduce "dead times"
(intervals of time when devices are not operational);
-
the OPC (OLE for Process Control) servers & clients facilitate interconnectivity
with other devices.

Abstract: This article
due to the constantly increasing level of automation used today in
various manufacturing processes, the engineers involved are confronted
almost every day with large amounts of data. Historical data represents
a valuable source of information which has to be distributed to
end-users and software clients interested in it. Currently, most of the
historical software engines available use their own interfaces for data
(re)distriubution, because it is more and more difficult to use other
methods in a plug-and-play environment. The aim of standardizing
historical data access is to allow various clients to have access to
historical data, regardless of their manufacturer or their inner
implementation, as long as they use the same standardized interface for
communication.

Abstract:There is a lot
of research in the area of load balancing at any level in distributed
systems. Unfortunately most models take into account homogenous
clusters. This approach makes the station and communication model more
simple, so the area of possible proposed algorithms for load balancing
is increased and sometimes their simplicity. The latest Internet
technology development drives to the necessity that the cluster must be
dynamic and also heterogeneous. In this paper a simulator for a
heterogeneous cluster used in distributed computing is presented.

Abstract: This paper
present algorithms and data structures for quick retrieval only
statistics needed for machine learning from large datasets. We focus on
constructing knowledge datasets by extract only data that match
conjunctive queries. Subject to certain assumptions, the cost of these
operations can be shown to be independent of the number of records in
the knowledge dataset.
This method can be used in rule
learning algorithms, Bayes net learning and we provide an empirical
result comparing to classical direct approaches.

UTILIZAREA RETELELOR NEURALE DE TIP B-SPLINE SI RBF PENTRU INTERPOLARE MULTIDIMENSIONALA
Valeriu Lupu
Universitatea "Stefan cel Mare" Suceava
lupu_2001@yahoo.com
Abstract. This paper presents the importance
of using B-spline and RBF neural network for multi-dimensional
interpolation. Radial basis functions are a natural generalisation of
univariate polynomial splines to the multivariate setting. They are
very attractive objects to use for multivariate fitting since: the
corresponding interpolation problems are uniquely solvable under very
weak conditions on the nodes. In particular, when the nodes do not lie
on a regular grid; the resulting interpolates can be characterised as
smoothest interpolations; radial basis functions also arise naturally
in non-parametric statistical fitting via generalised cross validation.
Keywords: B-spline and
RBF neural network, multi-dimensional interpolation

Abstract . FPGA's can be programmed to implement almost any digital circuit beginning with the
most simple ones like counters up to new microcontrollers and
processors. You can implement a hole standalone microcomputer with one
or more CPU's and all I/O standard controllers in the same FPGA chip.
But from Verilog (or VHDL) source to a complete working system it is a
long way that is passing through a lot of testing. You can make a CPU
for example and when testing, nothing is working like you expected. So
it is a good idea to find a solution to debug your processor or
anything you are doing with the FPGA. There are two solutions for this
problem: to use an expansion board with 7-segment displays and push
buttons or to create a communication protocol with the PC using the
I/O's of the FPGA.
