The bands below 30 MHz (AM) may have a new opportunity, with the help of digital terrestrial broadcasting. The engineer Ivan Pena provides some basis for the use of the band 26 MHz digital terrestrial broadcasting in DRM, in a thesis defended at the UPV / EHU.
Radio stations are scrambling to gain a foothold in the more popular FM, at the expense of AM with a poorer sound quality. However, the bands below 30 MHz (AM) may have a new opportunity, with the help of digital terrestrial broadcasting. The international consortium Digital Radio Mondiale (DRM) is working on developing a universal system that would offer close to the clarity of FM, as well as other benefits such as multilingual program option or a power reduction of 40-50% .
The engineer Ivan Peña, who works with DRM by Treatment Group and Radio Signal UPV / EHU, has focused specifically on the study of the band of 26 MHz on her doctoral thesis Planning factors for digital local broadcasting in the 26 MHz band(Factors of planning for local digital broadcasting in the band 26 MHz).
Peña’s research is the study of propagation models and planning factors for the implementation of DRM services in the band 26 MHz for this purpose, tests carried out locally in countries like Mexico, Brazil and Germany. Specifically, Mexico and Brazil were the first made with this system in two countries. In addition, 26 MHz is a band that has rarely been used so far, so optimization would have a major impact. So Peña’s research and the group it belongs to have been well received at international conferences and in magazine IEEE Transactions on Broadcasting, Who is ranked seven in the JCR telecommunications classification.

Mirage Technologies The company has developed a technology that can automatically convert stereoscopic images (3D) images autostereoscopic, ie that can be viewed in 3D with the naked eye without using special glasses. This is the only company in the world to offer this conversion service, which has already content producers to showcase their productions in 3D glasses-free 3D displays.
Based on the calculation of the depth in the couple of images that provides the stereoscopic-the one used in films and 3D-TV channels, the technique constructs a 3D model of the scene and calculates the additional views needed to autoestereoscopía (up to eight or nine) as if they took photographs of the virtual scene from different angles, mimicking what the eye would see from any position.

Temperature, soil moisture and vegetation, determine the possible emergence of a locust invasion, but these factors are monitored in areas where they occur. This is due to its complexity and the pests originated in large areas of land, mainly in Mauritania, south-east areas of Morocco and Sahara and Mali, and may also extend to other areas such as Egypt and even the southeast of the Iberian Peninsula . Therefore, at the University of Valladolid have been proposed to control them by remote sensing.

In order to monitor the factors affecting reproduction, development and expansion of locusts, the Remote Sensing Laboratory (LATUV), University of Valladolid working on a new project. “Using remote sensing techniques can understand and evaluate the extent and impact of this problem. This requires continuous monitoring of the development areas and the presence of conditions conducive to the emergence of swarms and then control their spatiotemporal evolution, detailed DiCYT LATUV director, José Luis Casanova .
There are several satellites through which images can measure the parameters of soil temperature and vegetation in areas of difficult access. It also stresses the expert, “by meteorological satellites can even know the rain that occurs in every area.” Knowing the soil temperature, moisture and vegetation amount then provides “a unique position to develop algorithms for prediction and monitoring of lobster that can serve to take precautions, control and reduce the problems that usually cause this type of event.”

Innoware Delacroy Company dedicated to designing and developing mobile applications, is preparing, with assistance from the University of Jaén, and within the SOS project Helpers, the activation of a web platform accessible from smart phones and any device with Internet connection . Users who register can check the information of those who have added, as the display of alerts and consultation in a precise map of the route via GPS of the person that triggered the alarm.
“If a victim says a brother, for example, the password can access all that has given warnings and even see the path that has since sent the message. The phone sends from time to time GPS positioning and brand on a map the path that led the person from triggering the alarm, “said David Mendez, Director Sales and Marketing Delacroy.
In addition, the platform will be available in a month and a half in five languages (English, Spanish, French, German and Portuguese) comprise a specific module dedicated to domestic violence where victims have access to information that can be of assistance to this risk. Such as what steps to take if they find her attacker. “These provide as much information as possible to victims of domestic violence,” said Méndez. For this they have advice on contents of the Professor of Psychology and cabinet responsible for gender violence UJA, Beatriz Montes.

The Institute of Automation and Industrial Informatics (Instituto ai2) of the Polytechnic University of Valencia was presented today at the Sixth Conference on Technology, Computer Graphics and Vision SENSE project (acronym for Smart Embedded Network of Sensing Entities), A security system to detect risk or abnormal behavior, such as dropping out of a suitcase in an airport.
The conference held today by the Institute AI2 of the UPV, which brought together experts and companies interested in the new security methods, has also hosted VICOM exposure (Visual Context Modelling), A European project involving universities and companies in various countries and can be considered an evolution of the SENSE project regarding the interpretation of the images are concerned. With Vicom recorded spaces can be viewed in 3D, and therefore a much more realistic.
This is precisely the project area developed by experts in Computer Vision ai2 Institute at UPV, which are testing the new smart security system in one of the terminals of the port of Valencia. The other European countries are involved by testing it in malls.
The Vicom work consists of three steps: first, the installation of smart cameras throughout the terminal, taking pictures of each corner of this room and collect data on the elements that move in it (staff, trucks, etc.). The second step is to model these 3D spaces and analysis of the distances and motions of each of these elements.
Finally, the system is able to analyze whether any behavior or unusual object within the terminal, so as to extract, from the pictures, simple conclusions for best performance of the same: a truck that has been off course, a professional who does not carry a reflective vest or an intrusion by a back door. In this way accidents can be prevented from theft or intrusion.
Ai2 Institute investigator, Oscar Ripoll, member of the team that developed the Vicom, explains that “these automatic surveillance systems intended to be, for now, support for security personnel of large workspaces as a port or airport. ”

Researchers at the Institute of Marine Sciences of the CSIC have developed a powerful method of analysis of singularities in digital signals to detect and recognize patterns from images or data sets. The method, patented worldwide, allows us to recognize structures, rebuild and enhance images and compress the signal. But above all, stands out because it can obtain relevant information from a very small set of data.
If one does not satisfy the mathematical definition, the singularities can be described as points that indicate an unexpected change. In a homogeneous space, the singularity is less regular points are breaks that indicate that something happens. Thus, a portrait that is losing resolution remains, even if it is fuzzy, the contour lines of the body and the factions are those unique items that reveal the main image information.
The example is provided by Antonio Turiel, Ramón y Cajal researcher at the Department of Physical Oceanography Institute of Marine Sciences (ICM) of the CSIC. This expert works in the development of ocean monitoring applications at different scales. Fruits of his labor and his team developed a mathematical method for the analysis of singularities into digital signals that can be applied to the monitoring of the ocean.
The algorithm, patented worldwide, allows many different applications that go beyond Oceanography: from defining the contours diffuse and subtle changes in medical diagnostic imaging, to detect defects in materials. They also show in the open ocean internal waves and streamlines oceanic flow, locating ships at sea from low-contrast images and images reconstructed from very limited data, implying that would improve the compressibility of the digital signal. “Regarding today’s standards, the maximum expected gain compression, with the same quality, is ten times, but it is a theoretical estimate,” said Turi.
