Amaç: Kız ve erkek yüzücülerde ısınma yapılarak yapılmadan 4 tekrarlı 50 metre (m) karışık yüzme performansındaki kulaç mekaniğinin karşılaştırılmasıdır. Gereç Yöntemler: Çalışmaya; 19 kız, toplam 38 yüzücü (Xyaş=12,58±0,50 yıl; Xvücutağırlığı=45,68±8,30 kg; Xboyuzunluğu=156,94±7,11 cm) gönüllü olarak katılmıştır. Yüzücülerin fiziksel ölçümlerinden 24 saat sonra sudaki performans ölçümleri gerç...

Model theory is a branch of mathematical logic that investigates the logical properties of mathematical structures. It has been quite successfully applied to computational complexity resulting in an area of research called descriptive complexity theory. Descriptive complexity is essentially a syntactical characterization of complexity classes using logical formalisms. However, there are still m...

We continue with the task of obtaining a unifying view of process semantics by considering in this case the logical characterization of the semantics. We start by considering the classic linear timebranching time spectrum developed by R.J. van Glabbeek. He provided a logical characterization of most of the semantics in his spectrum but, without following a unique pattern. In this paper, we pres...

This paper studies the descriptional complexity of multi-parallel grammars with respect to the number of nonterminals and selectors, and the length of these selectors. As a result, it proves that every recursively enumerable language is generated by a multi-parallel grammar with no more than seven nonterminals and four selectors of length five.
