PL
W artykule omówiono zagadnienia otwartej edukacji internetowej, w tym wolnodostępnych materiałów OER (ang. Open Educational Resources) oraz masywnych kursów online MOOC (ang. Massive Online Open Courses), a także statystyki oglądalności własnego kursu złożonego z filmów edukacyjnych z dziedziny informatyki.

Data obtained from modern movement analysis systems are challenging to analyse. There are several reasons for that: large number of data obtained during the session, their multi dimensionality, most of them are time dependent, often depend on each other. During last years many different analytical techniques are used to deal with them in order to better understand the physiology and pathophysiology of the human movement (especially gait). This paper presents most commonly used and promising techniques.

Liczba danych otrzymywanych obecnie ze współczesnych systemów analizy ruchu jest trudna do analizy. Składa się na to kilka przyczyn: duża liczba danych otrzymywanych podczas jednej sesji analizy chodu, ich wielowymiarowość, większość z nich charakteryzuje się zależnością od czasu, często są od siebie wzajemnie zależne. W ostatnich latach w literaturze przedmiotu pojawia się coraz więcej prac w których do opracowania danych pochodzących z analizy chodu stosowane są różne techniki analityczne. Ich zastosowane ma na celu lepsze zrozumienie fizjologii i patofizjologii ludzkiego ruchu (zwłaszcza chodu). Celem niniejszego artykułu jest przegląd najpopularniejszych i najbardziej obiecujących z nich.

Molecular computing created for implementing logic systems, solving NP-difficult problems on nanoscale depends on DNA self-assembly abilities and on modifying DNA with the help of enzymes during genetic operations. In the typical DNA computing a sequence of operations executed on DNA molecules in parallel is called an algorithm, which is also determined by a model of DNA chains. This methodology is similar to the soft hardware specialized architecture driven here by heating, cooling and enzymes, especially polymerases used for copying strings. This work presents a unique approach to implementation of OR, NOR logic gates on molecules. It requires the representation of signals by DNA molecules. The presented method allows for constructing logic gates with many inputs and for executing them at the same quantity of elementary operations, regardless of a number of input signals. The NOR gate was implemented with the help of modified polymerase Taq, which stops its activity, when it meets a molecular obstacle on its way. The appropriate experiment was conducted to confirm the possibilities of the suggested implementation. Laboratory results were discussed.

Molecular computation of DNA performs calculations using naotechnology means during chemical reactions. With the help of silicon industry microfluidic processors were invent utilizing nano membrane valves, pumps and microreactors. These so called lab-on-a-chips combined together with molecular computing create molecular-systems-on-a-chips. This work presents an approach to implementation of logic systems on chips. It requires the unique representation of signals by DNA molecules. The main part of this work includes the concept of logic inference based on typical genetic engineering reactions. The presented method uses a lab-on-a-chip approach. every microreactor of the lab-on-a-chip performs one unique operation on input molecules and can be connected by dataflow output-input connections to other ones.

Implementation of the inference system based on DNA chains molecular computing is a new paradigm to perform calculations using nanotechnology means. This work presents a new approach to the implementation of inference engines based on DNA. It introduces the subject of inference methods designed to be used with molecular expert systems. The main part of this work includes the concept of the inference engine based on a rule tree specially customized to allow implementation using deoxyribonucleic acid chains. The approach presented allows the drawing of inferences based on a variable number of predicates using the most reliable techniques employed in standard operations of genetic engineering. In this approach cross cells are bases of multidimensional DNA structures. An experiment was conducted to confirm the capabilities of the implementation suggested. In addition, laboratory evaluation results and perspectives for the further use of the proposed architectural approach are discussed.
