Presenter: Omero Costa Filho MD, MSc | Hospital Militar de Área Porto Alegre (HMAPA) Methods: Description of our conventional technique for LPD using hanging maneuver to expose uncinate process with the principles “artery-first” approach. Results: is performed patient placed in a supine, split-leg position and carefully secured operative table, surgeon on foot between legs, an assistant at each...

A b s t r a c t In this paper, we briefly discuss the dynamic and functional approach to computer symbolic tensor analysis. The ccgrg package for Wolfram Language/Mathematica is used to illustrate this approach. Some examples of applications are attached.

In this article, we propose a fuzzy class relation assigning to each pair of finite fuzzy sets a degree to which they are equipollent, which indicates that they have the same number of elements. The concepts of fuzzy sets and fuzzy classes in the class of all countable sets are introduced, and several standard relations and constructions, such as the fuzzy power set and exponentiation, are defi...

We take up the challenge of learning a grounded model of language when our agent has a body of machine learning algorithms and no prior knowledge of either the physical domain or language, in the sense of "least commitment". Based on a 2D video and co-occurring raw text, we demonstrate how this cognitively inspired model segments the world to obtain a meaning space, and combines words into hier...

We describe a convex relaxation for a family of problems of minimal perimeter partitions. The minimization of the relaxed problem can be tackled numerically, we describe an algorithm and show some results. In most cases, our relaxed problem finds a correct numerical approximation of the optimal solution: we give some arguments to explain why it should be so, and also discuss some situation wher...

The efficient siphon computation is the key to the development of siphon-based deadlock control strategies with good performance. This work studies the computation of minimal siphons in a class of Petri nets called SPR. Firstly, we propose a function with polynomial complexity to determine whether a resource subset can generate a minimal siphon. Next, using the technique of problem partitioning...

The concept of a forecast horizon has been widely studied in the operations management/research literature in the context of evaluating the impact of future data on current decisions in a multi-period decision making environment. As a solution approach for computing forecast horizons, integer programming has been largely ignored by the research community. However, the modelling and structural a...

To learn and mimic how the brain processes information has been a major research challenge for decades. Despite the efforts, little is known on how we encode, maintain and retrieve information. One of the hypothesis assumes that transient states are generated in our intricate network of neurons when the brain is stimulated by a sensory input. Based on this idea, powerful computational schemes h...
