Boolean operations mediated by an ion-pair receptor of a multi-readout molecular logic gate

2013

A heteroditopic BODIPY dye that performs all basic Boolean operations with a cation (K+) and an anion (F-) as inputs and absorption, transmission and fluorescence as outputs is described. The molecular logic gate can also act as a digital comparator between the inputs.

Temnothorax pilagens sp. n. – a new slave-making species of the tribe Formicoxenini from North America (Hymenoptera, Formicidae)

2014

A new species of the ant genus Temnothorax Forel, 1890 – Temnothorax pilagens sp. n. is described from eastern North America. T. pilagens sp. n. is an obligate slave-making ant with two known hosts: T. longispinosus (Roger, 1863) and T. ambiguus (Emery, 1895). A differential diagnosis against Temnothorax duloticus (Wesson, 1937), the other dulotic congener from the Nearctic, is presented and a biological characteristics of the new species is given.

Multiple-attribute decision support system based on fuzzy logic for performance assessment

2005

Abstract This paper deals with the problem of assessing the performance of a set of production units, simultaneously considering different kinds of information, yielded by a Data Envelopment Analysis, a qualitative data analysis and an expert assessment. The tool for integrating heterogeneous data is a model that applies fuzzy logic to decision support systems. The results obtained are a holistic performance assessment of each unit of the set and a ranking order of the units.

Spim-Cache: A Pedagogical Tool for Teaching Cache Memories Through Code-Based Exercises

2007

Cache memories represent a core topic in all computer organization and architecture courses offered at universities around the world. As a consequence, educational proposals and textbooks address important efforts to this topic. A valuable pedagogical help when studying cache memories is to perform exercises based on simple algorithms, which allow the identification of cache accesses, for instance, a program accessing the elements of an array. These exercises, referred to as code-based exercises, have a good acceptance among instructors of computer organization courses. Nevertheless, no tool (e.g., simulator) has been developed to be used in undergraduate courses working with this kind of e…

Combining traditional and indirect augmented reality for indoor crowded environments. A case study on the Casa Batlló museum

2017

Abstract Mobile audio-guides are currently being used in museums to enhance the visitors’ experience. Over the past few years, some Augmented Reality (AR) solutions have been explored in this context, making it possible to provide augmented visual and sonic stimuli through the use of smartphones. However, the special conditions of museums (e.g. artificial markers cannot be used, small, crowded rooms, etc.) and the limited computational capacity of smartphones mean that there are important restrictions in the use of this technology. In this paper we introduce a novel mobile augmented guide for the Casa Batllo museum (Barcelona, Spain) which is based on a combination of traditional and indire…

Diversification of adult education with the help of video lectures

2010

For some years now, adult education and working while studying have had an important role in the modern society. Mature-age study brings with it some special features, such as time use limitations, which must be taken into account when creating educational programmes for the students concerned. Above all, flexibility must become a major feature of participation in education. In relation to the Master Studies in Mathematical Information Technology at Kokkola University Consortium, the aim for some years now has been to increase that flexibility by diversifying traditional lecture teaching with the help of real-time and on-demand video lectures. With the help of the results presented in this …

Symbol, Munch and creativity: metabolism of visual symbols

2010

In this dissertation the relationship between visual symbols and creative thinking is studied through visual, textual and conceptual analysis. The first part of the work focuses on the concept of symbol, the second part on the imagery of Edvard Munch (1863–1944), and the third part on creative thinking. The problematics of visual symbols is approached through the concept of metabolism by assuming that both perceivable and non-perceivable properties of symbols can transform when symbols are used. Because visual symbols are frequently understood as conventional signs with fixed meanings, their perceivable properties are easily ignored. However, symbols can also be unconventionally used, for e…

Acute effects of static and dynamic stretching on the neuromuscular system

2019

Stretching is traditionally incorporated into pre-exercise routines in health, rehabilitation and sporting environments to condition the neuromuscular system for exercise. While a large body of evidence reported that stretching may acutely impair the subsequent muscular performance, some conflicting results highlight possible mitigating factors of neuromuscular responses variability. Because the limited data available do not present a clear consensus, the aim of this thesis was to investigate the effects of different factors on neuromuscular responses to stretch: the muscle group, the stretch duration and modality. By means of four studies, it has been shown that static stretching may alter…
