This paper presents a review of the worldwide application of geothermal energy for direct utilization, and updates the previous survey carried out in 2005. We also compare data from 1995 and 2000 presented at World Geothermal Congresses in Italy and Japan, respectively (WGC95 and WGC2000). As in previous reports, an effort is made to quantify ground-source (geothermal) heat pump data. The prese…
Acquisition of geomagnetic field has been done at Kretek, Sanden, Pundong, Bantul and Panggang, Gunung Kidul, Yogjakarta Province on 14 s/d 17 October and 7,8,9,12 November 2009 in orde to interpreted the subsurface structure. Data has been collected by Proton Precession Magnetometer (PPM) to measured the total intensity of magnetic field, Global Positioning System (GPS) to determine the pos…
The industry is producing new wireless mobile devices, such as smart phones, at an ever increasing pace. In terms of processors and memory, these devices are as powerful as the PCs were one decade ago. Therefore, they are perfectly suitable to become the first real-life platforms for ubiquitous computing. For instance, they can be programmed to run location-aware applications that provide peopl…
In this paper we present a modular system for remote monitoring and control of energy consumption. In particular, we demonstrate the application of the proposed system for electric energy monitoring and control in domestic or medium size office installations. This whole system is integrated in a single platform and consists of different modules: one or several smart plugs including a wireless c…
