As a result, most of the applications used require a more complex system in order to achieve a better performance. These systems have a mathematic background indicating the need of a better mathematical tool to increase the reliability of them. One of the most significant problems coming up

Membrane Computing, a branch of Natural Computing, is constantly producing interesting results the last 15 years. In this work we attempt to describe a mitochondrial fusion process based on membrane automata in a novel way. We combine these computation machines with notions from brane calculus and we depict the procedure of the production of specific proteins that are essential for a successful fusion. We also discuss possible extensions of our methodology stating direction for future works and thoughts.

Parts of these works concern the query process of Linked Data using SPARQL. Our work examines the querying of such data sources which are characterized by eventual computability, rather than finite. This infinite character of the data and the query process stimulated the use of Büchi automata in order to properly verify this computation model. In brief, our work contributes by presenting a novel approach to describe the infinite computation of SPARQL queries on a Web of Linked Data using Büchi automata.

However, the mechanism behind these operations is yet not sufficiently clear. In this work we present a novel approach to describe a biomolecular model for mitochondrial fusion using notions from the membrane computing. We use a case study defined in BioAmbient calculus and we show how to translate it in terms of a P automata variant. We combine brane calculi with (mem)brane automata to produce a new scheme capable of describing simple, realistic models. We propose the further use of similar methods and the test of other biomolecular models with the same behaviour.

become popular with smart phone users who are concerned about
their health and fitness. Nevertheless, there is limited research
on the user requirements for sports tracking software, which
needs to be fun and easy to use in order to appeal to a broad
set of users. For this purpose, we employed a four-week long
experiment with five users who were asked to perform multiple
workouts with two levels of gamification. The first treatment
stands for “no gamification” and the second treatment provided
rich visual feedback, such as speed, distance, elapsed time, map.
At the end of the experiment, we asked users to describe the
devices. Both devices included GPS sensor, so we also measured
the distance covered for each one of the workouts. We found
that augmented feedback from mobile self-tracking devices can
promote working out, but there is also a trade-off of increased
anxiety and disorientation. Thus, we suggest that sports tracking
software should be modest about how much and what type of
visual information it provides to the user. In particular, we found
that the only piece of visual information that had an impact on
performance was average speed, which indicates a connection
with gamication. Further research should consider additional
levels of gamification beyond score, such as graphics, sociability,
rules.

At first we present a summarized review of terms and facts regarding the branch of ecoinformatics, web mining and the semantic web. In Section 2 we provide some related work derived from the current literature upon the web mining and the production of semantic content. The main part of our work follows presenting a notional model for building semantic content through 2-level web mining. This is achieved in web sites containing environmental data. We conclude mentioning the importance of this contribution from different points of view.
