Desterrados
by Bravo Alfredo Molano«Cuando mataron a Jaime Garzón admití que no podía regresar pronto, conseguí una mesa de trabajo grande, alé la pluma y comencé a escribir este libro. Al terminarlo comprendí agachando la cabeza en señal de profundo respeto que el drama de mi exilio, a pesar de sus dolores, es un pálido reflejo de la auténtica tragedia que viven a diario millones de colombianos desterrados, exiliados en su propio país. Creo, con ellos, que sólo un acuerdo político profundo permitirá echar las bases de una verdadera democracia; la guerra no tendría resultado distinto a la dictadura de los vencedores».Alfredo Molano

Destinazione Marte - L’anno 2030, il viaggio spaziale e il nostro destino oltre la Terra
by Adidas WilsonOggi tutti sembrano interessarsi a Marte. La NASA progetta l’invio di esseri umani su Marte per il 2030, mentre la SpaceX vuole farlo prima, nel 2024. Marte è un argomento ricorrente a Hollywood. Ci sono film, come The Martian e Life, che ipotizzano su come potrebbe essere la vita sul pianeta rosso. Tuttavia, nessuno di questi film sembra affrontare il problema fondamentale: come faranno gli esseri umani a vivere su Marte nel lungo periodo? L’atmosfera di Marte è composta, principalmente, di monossido di carbonio e la sua superficie è troppo fredda per la vita umana. La gravità è pari al 38% di quella terrestre. Di conseguenza, resta la questione di come un essere umano possa sopravvivere in un ambiente simile. Andare su Marte è facile, poiché il viaggio richiede soltanto 260 giorni quando i due pianeti sono più vicini l’uno all’altro. Dopo essere arrivati, la difficoltà è atterrare sulla superficie. Quale sistema di atterraggio è più sicuro per astronauti e coloni? Nel 2007, gli scienziati hanno proposto quattro sistemi di atterraggio: il Legged Standing System, lo Sky-Crane Landing System, l’Airbag Landing System e infine il Touchdown Sensing. Al 2017, gli scienziati hanno trovato altri metodi di atterraggio, tra cui tuffarsi nell’atmosfera marziana e costeggiare più da vicino la superficie. La NASA sta già pensando al tipo di abitazioni che aiuteranno i coloni a sopravvivere su Marte. Nel 2016, sei aziende hanno iniziato a progettare prototipi di possibili habitat. Tutti questi prototipi sono probabilmente simili sotto molti aspetti – dovrebbero essere autosufficienti, in grado di sostenere la vita per lunghi periodi senza aiuto dalla Terra ed essere a tenuta stagna per protezione dalla sottile atmosfera di Marte.

Detection Efficiency and Bandwidth Optimized Electro-Optic Sampling of Mid-Infrared Waves (Springer Theses)
by Christina HoferThis thesis investigates the detection efficiency of field-resolved measurements of ultrashort mid-infrared waves via electro-optic sampling for the first time. Employing high-power gate pulses and phase-matched upconversion in thick nonlinear crystals, unprecedented efficiencies are achieved for octave-spanning fields in this wavelength range. In combination with state-of-the art, high-power, ultrashort mid-infrared sources, this allows to demonstrate a new regime of linear detection dynamic range for field strengths from mV/cm to MV/cm-levels. These results crucially contribute to the development of field-resolved spectrometers for early disease detection, as fundamental vibrational modes of (bio-)molecules lie in the investigated spectral range.The results are discussed and compared with previous sensitivity records for electric-field measurements and reference is made to related implementations of the described characterization technique. Including a detailed theoretical description and simulation results, the work elucidates crucial scaling laws, characteristics and limitations. The thesis will thus serve as an educational introduction to the topic of field-resolved measurements using electro-optic sampling, giving detailed instructions on simulations and experimental implementations. At the same time, it showcases the state-of-the-art in terms of detection sensitivity for characterizing mid-infrared waves.

Detection of Corona Discharge in Electric Networks (Studies in Systems, Decision and Control #509)
by Artur Zaporozhets Yevgen Sokol Vitalii Babak Oleg Gryb Ihor KarpaliukThe book is devoted to the solution of the problem of determining the presence of corona discharge on electrical equipment with acoustic radiation. It is shown that corona discharge leads not only to irreversible losses of electrical energy, but also interferes with the transmission of high-frequency signals, deteriorates insulating elements, can become a source of conditions for the occurrence of a destructive arc discharge and is one of the factors of changing the continuity of the electrical system as a whole. The book describes the processes in a corona discharge that lead to the occurrence of acoustic waves. The authors analyzed acoustic radiation from a corona discharge reproduced in laboratory conditions. The received acoustic signals were processed by Fourier transform. Thus, the features of the spectral function, which belong specifically to the corona discharge in electrical networks with industrial frequency current, were determined. Based on the inverse Fourier transform, a simplified model of the acoustic radiation of the corona discharge was constructed. The authors proposed a method for detecting the presence of a corona discharge based on the spectral characteristics of acoustic radiation. Techniques were developed to determine the presence of a corona discharge for the creation of stationary and mobile devices. The advantages of the method of detecting the presence of corona discharge by the acoustic spectrum are shown. The method makes it possible to determine the presence of a corona discharge remotely, even out of direct sight, regardless of the time of day and regardless of the season. The book states that determining the presence of a corona discharge is not enough, it is still necessary to determine its location. The method of finding the coordinates of the corona discharge as a source of sound was described. Methods of searching for corona discharge coordinates with a fixed scanning device and a moving scanning device are proposed. A UAV is proposed as a mobile platform for the scanning system. The influence of the Doppler effect on acoustic measurements when the UAV speed changes was taken into account. The authors have shown that the use of coronal discharge detection with UAVs will not only enable the prevention of coronal discharge, but also increase the frequency of surface inspections. This will allow timely measures to be taken to improve the reliability of the power system operation. The book is intended for the researchers, postgraduate students and students specialized in theory and calculations of electrical systems.

Detection of Fetal Abnormalities Based on Three Dimensional Nuchal Translucency
by Khin Wee Lai Eko SupriyantoUltrasound (US) prenatal screening has been proposed as the most effective technique for Trisomy 21 early assessment. Assessment of Nuchal Translucency (NT) offers promising non-invasive method for fetal abnormalities detection up to 75%. Nevertheless, current clinician practice of NT examination by locating the sonogram calipers on 2D US image requires highly trained and competent operators by adhering to a standard tedious protocol; therefore it is prone to errors and hence it decreases the reliability in intra- and inter-observer repeatability. This Brief provides the basic knowledge regarding Trisomy 21 diseases and its existing detection methods. The restrictions and disadvantages of each method are discussed accordingly. Therefore, a non-invasive early detection method using 3D ultrasound reconstruction of Nuchal Translucency is introduced. This new method for 3D NT assessments has an edge over the previous 2D methods, and entails the composite function in visualizing the explicit internal marker structure. Further, image processing techniques covered from data acquisition, pre-processing, speckle noise reduction and 3D segmentation are also discussed. This should be especially useful for students and professional researchers in the Biomedical and image processing fields.

Detection of Melt Ponds on Arctic Sea Ice with Optical Satellite Data
by Anja RöselThe Arctic sea ice is characterized by profound changes caused by surface melting processes and the formation of melt ponds in summer. Melt ponds contribute to the ice-albedo feedback as they reduce the surface albedo of sea ice, and hence accelerate the decay of Arctic sea ice. To quantify the melting of the entire Arctic sea ice, satellite based observations are necessary. Due to different spectral properties of snow, ice, and water, theoretically, multi-spectral optical sensors are necessary for the analysis of these distinct surface types. This study demonstrates the potential of optical sensors to detect melt ponds on Arctic sea ice. For the first time, an Arctic-wide, multi-annual melt pond data set for the years 2000-2011 has been created and analyzed.
