Sound measured at various points around the environment can be evaluated by a series of multi-pole sources and their acoustic strength can be acquired. In this numerical study, a method, called the inverse method, was examined to achieve this goal. A variety of arrangements of different sources were considered and the acoustic strength of these sources was acquired. Through the application of t...

Digital memorials are currently addressed in several studies on the design this type of system requires. However, as different types have needs, research analyzes characteristics software terms design, structural elements, cultural relevance etc. This paper presents an overview recommendations for digital memories from published articles and sums them up.

Abstract In this paper, we introduce the notion of a complete hypertetrahedral arrangement $${\mathcal {A}}$$ A in $${\mathbb {P}}^{n}$$ P n . We address two basic problems. First, describe local freeness terms smaller arrangement...

where Q is an n × n rational symmetric matrix, is a classical NP-hard combinatorial optimization problem. It is well known that the weighted max-cut problem can be considered as a special case. In fact, there are simple polynomial reductions between the weighted max-cut problem and the 01QP. This intereting result, due to [13], will be reviewed in subsection 2. The 01QP problem remains NP-hard ...
