The conference, which takes place in the United States, is one of the most important on subjects related to Laser applications, and there were more than 1,500 scientific articles presented at this encounter. Last Monday, Uta gave a talk titled “Delocalization enhancement induced by weak disorder and nonlinearity,” and on Thursday the 10th she presented the poster “Boundary – induced Anderson localization in a photonic lattice.”

CLEO is organized by the Optical Society of America, and is the conference on lasers and opto-electronics known for being the main international forum for scientific and technical optics, uniting all aspects of laser technology, from basic research, to industrial applications. In addition, it presents high quality themes from five fundamental areas: Fundamental Science, Science and Innovations, Applications and Technology, Market, and Exhibitions.

The presentation included the review and research that he carried out on the available material to verify the current status of GNSS operation, accuracy, and other characteristics, to later apply this knowledge to new tsunami early warning systems and thus to see some possible improvements to their alert implementations, for example, creating a project that encompasses the new warning techniques and those we currently possess.

The Evaluation Committee consisted of Dr. Rolando Hernández, Technology Development Director of our Center and the thesis advisor of Jesus; Dr. Felix Borotto, and Dr. Claudio Faúndez, all of the Physics Department. The academics emphasized the scientific rigor, the relevance, and contingency of the data used and the contribution of the project presented by Jesus, who commented on this last point that “the techniques presented have been implemented, however, there is no project that involves them in a comprehensive manner.”

While acknowledging the commission, Jesus Gonzalez said that his plans are to pursue a graduate degree in “magnetic resonance”.

This conference took place in Brussels (Belgium) and is known for being one of most important in the area of Photonics, including a variety of themes, such as: nanophotonics, biophotonics, micro-optics, laser sources and applications, organic photonics, photonics for solar energy systems, optical sensing and detection, nonlinear optics, metamaterials, quantum optics, optical modelling and design, optical micro- and nanometrology, photonic integrated circuits, laser dynamics, optical fibers, image and video processing, and optical technology, among others.

Dr. Molina was invited by the organizing committee in the area of metamaterials and his talk was titled “Localized resonances and embedded states in magnetic metamaterials.”   “It was an invited presentation, that dealt with three seemingly disconnected problems, but that in fact were complementary, and whose integrated vision allows us to better appreciate the basic phenomena behind these new optical materials,” the researcher explained.

The talk was presented to the “metamaterials” community, a new area that mixes elements of optics, solid state physics, and nonlinear physics with the aim of designing new materials with unusual optical properties, such as negative refractive index and invisibility.

This recognition is awarded by the last generation of graduates of Civil and Electrical Engineering of the University de la  Frontera (UFRO), in this case those who received their degree in 2011. This group chooses a single academic and gives the prize at the official graduation ceremony that involves all University degrees.

In this sense, explains César San Martin, the students highlight the professor who has most influenced their academic formation during their years of study, and who they consider to have given them the best example, not only by having had classes with him, but also in a comprehensive way. “This refers to all the benefits that a student could have obtained from an academic, that stands out above the others, and that also considers treatment outside the classroom, the delivery of values and life experiences, something beyond a mere delivery of knowledge,” the researcher emphasized. He points out:

“It is deeply satisfying to receive this recognition for the first time, since it helps you to realize that you are carrying out your work in the best manner, and with the most enthusiasm and energy, to receive this recognition adds an extra motivation to do it even better, to surpass yourself and to give still more.”

Along with thanking the 2011 graduates of the Civil and Electrical Engineering program of UFRO, César San Martin explains that during his teaching career – which he point out, is just beginning – “I have tried to be a comprehensive professional with each student, and to transmit to them that they should focus on reaching the main objective of their lives, and look beyond problems or difficulties. This motivates you to make a greater effort to grow, to give and to train people for the future of our country.”

Abstract:
The main activities at the TIGO VLBI station during 2011 have been: 121 succesful VLBI sessions enabling post-earthquake monitoring, the development of a VLBI control software for smartphones, encoder replacement and beamsize analysis measurements.

The paper, “Hardware-Based Computation of the Roughness Index for Infrared Imagers”, was presented at SPL 2012 by Rodolfo Redlich, who explained that, “The work presents an implementation in FPGA of the roughness index, to use as a gauge to assess the quality of infrared images in real time. Because the aim is the incorporation of this system in non-uniformity correction algorithms for infrared chambers, the main criteria of the design was to obtain a low- consumption circuit of reduced size, thus producing the least possible impact on the already existing hardware.” He adds that, “Our system manages to operate on line with images of 720×480 pixels resolution to 30 pictures per second comfortably (could operate to 180 pictures per second). The prototype, implemented in the FPGA of low cost Spartan3E XC3S500, makes use of around 6% of the chip, consuming around 1,56 mW.”

The prize obtained in this conference corresponds to the “Xilinx Best Paper Award”. The winner is selected by the technical program committee based on the paper with the best evaluation that made use of Xilinx FPGAs.

To be chosen as best paper, explains Miguel Figueroa, researcher, and Rodolfo Redlich, student, implies that, “Not only is it a work with good results, but it also demonstrates quality and relevance in the eyes of colleagues involved in the area. I also think that it helps to not only notice Chile, but also the University of Concepción and CEFOP at the conference, especially since we were the only Chileans that participated; obtaining the recognition as the best paper demonstrates that we are doing things really well here.” Redlich emphasizes that, “From the moment I finished presenting the work, it was obvious that it aroused considerable interest on the part of the audience, which was gratifying to experience as one of the authors of the paper.”

Along with these facilities, the construction of a second laboratory for the Biophotonics line has also begun, and it will house experiments associated with CARS and SHG. This new laboratory costs 5 million pesos, and it will be inaugurated next June.

Abstract:
Internet applications are always demanding more and more bandwidth where congestion control algorithms work hard to avoid network collapse and keep a fair and efficient network resources utilization. These algorithms are being evolving since Internet birth following the evolution of technology and new networking scenarios, however, despite the wide number of congestion control approaches, such algorithms mostly rely on forced packet losses to infer bandwidth availability. This work introduces a new approach, where the measure of a number of network metrics can give reliable and smoother information to determine the optimal load point with no need of packet losses at all, minimizing stress on middle nodes and therefore reducing its impact on other flows sharing a bottleneck.
