Optical flow estimation from multichannel spherical image decomposition
2011
The problem of optical flow estimation is largely discussed in computer vision domain for perspective images. It was also proven that, in terms of optical flow analysis from these images, we have difficulty distinguishing between some motion fields obtained with little camera motion. The omnidirectional cameras provided images with large filed of view. These images contain global information about motion and allow to remove the ambiguity present in perspective case. Nevertheless, these images contain significant radial distortions that is necessary to take into account when treating these images to estimate the motion. In this paper, we shall describe new way to compute efficient optical fl…
Restricted Neighborhood Search Clustering Revisited: An Evolutionary Computation Perspective
2013
Protein-protein interaction networks have been broadly studied in the last few years, in order to understand the behavior of proteins inside the cell. Proteins interacting with each other often share common biological functions or they participate in the same biological process. Thus, discovering protein complexes made of groups of proteins strictly related, can be useful to predict protein functions. Clustering techniques have been widely employed to detect significative biological complexes. In this paper, we integrate one of the most popular network clustering techniques, namely the Restricted Neighborhood Search Clustering (RNSC), with evolutionary computation. The two cost functions in…
Using crowdsourcing for a safer society: When the crowd rules
2020
Neighbours sharing information about robberies in their district through social networking platforms, citizens and volunteers posting about the irregularities of political elections on the Internet, and internauts trying to identify a suspect of a crime: in all these situations, people who share different degrees of relationship collaborate through the Internet and other technologies to try to help with or solve an offence. The crowd, which is sometimes seen as a threat, in these cases becomes an invaluable resource that can complement law enforcement through collective intelligence. Owing to the increasing growth of such initiatives, this article conducts a systematic review of the litera…
Employing fuzzy logic in the diagnosis of a clinical case
2010
Fuzzy logic is a logical calculus which operates with many truth values (while classical logic works with the two values of true and false). Since fuzzy logic considers the truth of scientific statements like something softened, it is fruitfully applied to the study of biological phenomena, biology is indeed considered the field of complexity, uncertainty and vagueness. In this paper fuzzy logic is successfully applied to the clinical diagnosis of a patient who suffers from different diseases bound by a complex causal chain. In this work it is presented a mathematical foundation of fuzzy logic (with connectives and inference rules) and then the application of fuzzy reasoning to the study of…
Estimation of Electrical Pathways Finding Minimal Cost Paths from Electro-Anatomical Mapping of the Left Ventricle
2014
The electrical activation of the heart is a complex physiological process that is essential for the understanding of several cardiac dysfunctions, such as ventricular tachycardia VT. Nowadays, electro-anatomical mappings of patient-specific activation times on the left ventricle surface can be estimated, providing crucial information to the clinicians for guiding cardiac treatment. However, some electrical pathways of particular interest such as Purkinje or still viable conduction channels are difficult to interpret in these maps. We present here a novel method to find some of these electrical pathways using minimal cost paths computations on surface maps. Experiments to validate the propos…
Industrial Areas and the City. Equalization and Compensation in a Value-Oriented Allocation Pattern
2016
This study deals with the allocation of the firms in a large industrial area of Quarto, a town in the Naples’ district subject to a “Piano di Insediamenti Industriali” – PIP (Industrial Settlement Masterplan). The main concern of the Municipality is the fair integration between environmental issues, economic development and urban identity. Therefore a structured evaluation process, based on a survey about the company profiles and their geographical location, has been carried out in order to make the plan meet the needs of the firms, and to select the best companies to settle in the planned area. A “generative” MAVT pattern has been designed to outline several layout options and to select th…
Miejsce międzypokoleniowego uczenia się w procesie hominizacji
2016
This article presents the results of a pilot and exploration study. The main objective of the research was to investigate the differences of intergenerational learning in the process of hominisation. For the purpose of the study the author used the quantitative strategy of research and author’s instrument of measurement. In the study participated 50 adult respondents from province opolskie. The research in question combines in a way such fields of knowledge as anthropology, pedagogics and psychology; the aim of the combination is to explore the processes which support the development of a human being in light of andragogy. Two conceptions have constituted the theoretical and methodological …
Activities with Educational Robotics: Research Model and Tools for Evaluation of Progress
2019
The use of robots in the learning process has been popular since S. Papert developed his LOGO Turtle idea and argued that students can construct their own knowledge, test their constructive solutions and be motivated to learn if they use robotics in the learning process. Today, the idea of using elements of robotics in the learning process is no longer new and innovative but there are still elements that can be developed and issues that should be discussed. In this chapter, the authors provide the research model and five research tools (structured observation protocol, evaluation of the possible risks of early school leaving to be filled in by teachers before and after activities, students’…
Complying With the First Law of Robotics: An Analysis of the Occupational Risks Associated With Work Directed by an Algorithm/Artificial Intelligence
2020
It is increasingly common for companies to use artificial intelligence mechanisms, which may be more or less advanced, to manage work, that is, to establish work shifts and production times, design and allocate tasks for workers, recruit workers, evaluate performance and dismiss employees. Companies rely on technology to gather all the information available, process it and make the management decisions (productivity optimisation) that will benefit them the most. This replaces human supervisors and middle managers, as well as experts in human resources, leaving the management of workers in the hands of automated processes directed by algorithms – or in its most advanced stage, to be undertak…
Rigal — a programming language for compiler writing
2005
A new programming language for compiler writing is described. The main data structures are atoms, lists and trees. The control structures are based on advanced pattern matching. All phases of compilation, including parsing, optimization and code generation, can be programmed in this language in short and readable form. Sample compiler written in RIGAL is presented.
