New mapping techniques on coastal volcanic rock platforms using UAV LiDAR surveys in Pico Island, Azores (Portugal)

Focal atrial tachycardia (AT) is a relatively uncommon cause of supraventricular tachycardia, but when present is frequently difficult to treat medically. Atrial tachycardias tend to originate from anatomically determined atrial sites. The P-wave morphology on surface electrocardiogram (ECG) together with more sophisticated contemporary mapping techniques facilitates precise localisation and ablation of these ectopic foci. Catheter ablation of focal AT is associated with high long-term success and may be viewed as a primary treatment strategy in symptomatic patients.

There are three objectives of this research. First, to map springs location, second to know spring characteristic and third to calculat springs potency for domestic use. To reach these aims, springs location were plotted on map base on its coordinate. Springs characteristic were analysed descriptively by spatial analysis base on geologic, geomorphologic and hydrogeologic conditions. Springs potency were calculated base on its discharge, whereas domestic use was determined 60 l/person/day for rural and 120 l/person/day for urban area. The study shows, that springs distribution in Bali Island are not homogeny Springs appearance were controlled by geologic structure as fault and rock contact. The differences of discharge also depend on the structure. Contact between volcanic rock (tuff and lahar) from Buyan-Bratan-Batur Formations with another rock formation in its surrounding result many springs appereance with high discharge. Beside that, orohydrology properties of Agung Mount as strato volcanic result springs belt in a certain elevation and each slope changing. Base on calculation, springs potency in Bali Island are 628.800 m3/month,whereas the domestic use is 9.079.990 m3/month. So, the springs potency is just 6,9% from domestic use in Bali Island.Key words : springs potency, springs distribution, springs characteristic

Abstract This work presents advanced resistance mapping techniques based on Scanning Electron Microscopy (SEM) with nanoprobing systems and the related embedded electronics. Focus is placed on recent advances to reduce noise and increase speed, such as integration of dedicated in situ electronics into the nanoprobing platform, as well as an important transition from current-sensitive to voltagesensitive amplification. We show that it is now possible to record resistance maps with a resistance sensitivity in the 10W range, even when the total resistance of the mapped structures is in the range of 100W. A reference structure is used to illustrate the improved performance, and a lowresistance failure case is presented as an example of analysis made possible by these developments.
