Summary: In the report it is considered the method of the underwater
vessel noise detection. It is assumed that the underwater vessel noise is a
sum of normal stochastic process and harmonic components. It is considered
the likelihood ratio and the algorithm of optimum detection of the
underwater vessel noise in the sea noise. The optimum detection probability
measure is given too.

Summary: An idea of hypertext system is described in this paper.
Hypertext is an organizational form of text material, with
machine-supported direct links, both within and between documents.
Hypertext systems are computer systems used to create and maintain
hypertext databases and provide mechanisms for users to access the
information.

Title: THE PASSIVE SONAR OPTIMAL STRUCTURE

Proceedings title: Elmar - zbornik radova
Language: hrvatski

Pages: from 270 to 274
Meeting: 35. međunarodni simpozij ELMAR-a
Held: from 06/28/93 to 06/30/93
Summary: The report deals with the passive sonar signal statistical
detection. It is assumed that the signal (vessel noise) is stochastic
process and that the interference (sea noise) is colored Gaussian noise.
The Neyman-Pearson criterion of the Bayes family of likekihood ratio tests
is used. The block-scheme of the optimal structure is considered.

Summary: Visual programming languages use pictures to express
meaning. They enable programming with visual, graphical expressions,
providing thus easier and more natural communication between man and
computer. The difficulties in specifying visual programming languages arise
from the multidimensional nature of pictures. Pictures contain complex and
diverse relationships between components, which require powerful mechanisms
to describe.
The paper presents a variety of approaches to the spcification of visual
programming languages, which attempt to find a formal model for the
definition and processing of languages of pictures.
A classification of mechanisms according their characteristics is done in
the table.

Summary: The problem of the statistical optimum detection of the
extremely weak and sophisticated underwater signal is considered. The
signal is supposed to be a normal stochastic process, the sum of the two
essential parts statistically independent: the wideband component and the
narrowband component. Based on this, the mathematical model of the signal
power spectral density is defined. The deep sea random noise is supposed to
be a normal stochastic process as well, and its mathematical model of the
power spectral density is also being defined. In order to sinthesize the
optimum structure, both the likelihood ratio statistical test and the
Neyman-Pearson criterion are used. To evaluate the optimum structure
performance, the receiver operating characteristics diagram is
investigated, showing that this optimum structure has its full
justification.
