Adaptive Ascent Control of a Collaborative Object Transportation System Using Two Quadrotors.

The paper focuses on the issue of collaborative control of a two quadrotor (Unmanned Aerial Vehicle QDR) system. In particular, two quadrotors perform the task of horizontally transporting a long payload along a predefined trajectory. A leader-follower method is used to synchronize the motion of both QDRs.

Intelligent Controller Design by the Artificial Intelligence Methods.

With the rapid growth of sensor networks and the enormous, fast-growing volumes of data collected from these sensors, there is a question relating to the way it will be used, and not only collected and analyzed. The data from these sensors are traditionally used for controlling and influencing the states and processes. Standard controllers are available and successfully implemented.

Correction to: Medical Image Retrieval Using Vector Quantization and Fuzzy S-Tree.

The article Medical Image Retrieval Using Vector Quantization and Fuzzy S-tree, written by Jana Nowaková, Michal Prílepok and Václav Snášel, was originally published electronically on the publisher's internet portal (currently SpringerLink) on December 15, 2016 without open access.

Medical Image Retrieval Using Vector Quantization and Fuzzy S-tree.

The aim of the article is to present a novel method for fuzzy medical image retrieval (FMIR) using vector quantization (VQ) with fuzzy signatures in conjunction with fuzzy S-trees. In past times, a task of similar pictures searching was not based on searching for similar content (e.g.

Colorectal cancer liver metastases: laparoscopic and open radiofrequency-assisted surgery.

Introduction: The liver is the most common site of colorectal metastases (colorectal liver metastases - CLM). Surgical treatment in combination with oncological therapy is the only potentially curative method. Unfortunately, only 10-25% of patients are suitable for surgery.

Radiofrequency-assisted liver resections: comparison of open and laparoscopic techniques.

Background/aims: After the first reported laparoscopic liver resection (LLR) twenty years ago, liver surgery still remains one of the last areas of resistance to the offensive of laparoscopy. Radiofrequency assisted laparoscopic liver resection has been recently developed technique for treatment of primary and secondary liver tumors.

Methodology: Over a 5-year period, a total of 134 laparoscopic and open radiofrequency assisted operations were performed in a single institution.

Technical development of a new semispherical radiofrequency bipolar device (RONJA): ex vivo and in vivo studies.

The aim of this study is to inform about the development of a new semispherical surgical instrument for the bipolar multielectrode radiofrequency liver ablation. Present tools are universal; however they have several disadvantages such as ablation of healthy tissue, numerous needle punctures, and, therefore, longer operating procedure. Our newly designed and tested semispherical surgical tool can solve some of these disadvantages.
