Last September 14th, our partner Nicolás Calvo Cruz gave his talk in the 27th edition of the Jornadas de Paralelismo national conference. The event, which was held in Salamanca this year, lasted from Septembed 14th to September 16th. There were numerous interesting talks about different topics such as vide HEVC coding, agent-based simulations and hyperspectral image processing. The work of our partner, entitled "Aplicando un procedimiento de optimización paralelo Teaching-Learning para el enfoque automático de helióstatos", was also of interest for the attendants and some questions were asked about its details. Next, the reference of the work is included for anyone interested at it:

Last Friday, September 30th the third edition of the "European Researcher's Night" event was held. This divulgative expo is concurrently celebrated in numerous cities of Europe by different institutions. As expected, the research group "Supercomputación y Algoritmos" also joined the event in order to show its activity to the general public and to capture people's attention as potential students of Computer Science. The event was a complete success and people of all ages came to our stand, placed in the middle of the Almeria's Rambla, to enjoy our activities.

The experiments shown are listed below:

  • TextCamera: How would a picture be if formed only by ASCII characters? This activity shows an example of image processing and device interaction from a low-cost computing environment and potential applicability to Internet of Things, the Raspberry Pi.
  • FruitPiano: Making music with fruit. This activity shows both a processing Raspberry Pi and a MakeyMakey board which allows launching events and actions from extra electrical circuits. In this environment, a piano whose keys were different vegetables was built.
  • Chip-8: Emulating a virtual machine from late 70's. This activity shows an amulator of Chip-8, a virtual machine from late 70's, in action in a Raspberry Pi. Games and software for that platform are shown and described, ranging from the classic Space Invader to an interesting magic trick.
  • LEDCube: 3D matrix of LED's. This activity shows an attractive lightning matrix formed by 512 LED's and controlled by an Arduino micro-controller which was built as a practical activity by students of the UAL.
  • Raspberry Pi cluster: Combining forces. This activity shows a low-cost cluster, built by a student of the UAL as his final degree project, which combines four Raspberry Pi to execute programs in parallel.
  • Presentation video: ¿What research lines are followed by the members of the group? This activity contains a screen in which a presentation video with information of the research group, its members, the problems that they try to solve and their advances is played.
  • PaperJoystick: Controlling videogames with a paper-drawn controller. This activity is formed by a Raspberry Pi in which an emulation-oriented operating system is executed featuring emulators of some widely-known video-game consoles such as the GameBoy-Advance. What is interesting is that, by using the MakeyMakey board, the controller is just a paper sheet in which the buttons have been drawn with conductive ink.
  • DomoticSample: Activating devices from the cell-phone. This activity is formed by an Arduino micro-controller with a GSM module, a relay and a colorful lamp. The lamp can be telematically activated with a simple and free phone call.
  • P2PSP: Collaborative video streaming. This activity shows a set of three laptops and a webcam. The webcam is recording in real time and this information is sent to one of the laptops which creates a P2P team based on the P2PSP protocol, actively developed by members of the group, with the other two laptops.

To conclude this press release regarding the event, a picture with some of the members who collaborated is shown next:

Researchers Night 2016

From 4th to 8th of September, the XIII Global Optimization Workshop GOW’16 was held in Braga (Portugal) and a large part of our research group members attended. It was a great opportunity to swap ideas, to know about other research lines, to share interesting problems and to learn about new methodologies to solve them.

Moreover, our group presented some of its latest research works at the following talks, whose extended resumes can be found at the proceedings book:
