Validity and reliability of end-user computing satisfaction in Indonesian language to measure digital nursing assessment tool Thermodynamic analysis of the effect of reservoir temperature change on the performance of organic rankine cycle system on geothermal power plant Abstract. Nowadays monitoring systems are designed with embedded technology such as Wireless Sensor Network. A communication stack based on IPv6 for low power devices named 6LoWPAN gives a great opportunity for sensor networks to communicate with the Internet using IP. However, with a few differences between the 6LoWPAN protocol stack and IP protocol stack, it is difficult for 6LoWPAN sensor networks to be operated from the Internet directly. In order to be directly connected to IPv6 networks, tunneling is required. Therefore, tunneling process test on 6LoWPAN network to connect to IPv6 networks needs to be done to show how each 6LoWPAN nodes will be accessible through the edge node and IPv6 network. In this research, we have conducted experiments to design the 6LoWPAN networks and test the tunneling process on 6LoWPAN network to connect with IPv6 networks. We have created a 6LoWPAN network with one edge node and two end nodes. The result shows that each node will be accessible using its IPv6 address through the edge after tunneling process is successfully executed. This research can become an insight for further studies on 6LoWPAN protocol stack as a part of the WSN-based monitoring system in movement.

Optimization of geothermal power plant design for evolving operating conditions

“…Using a detailed off-design simulation model for the ORC power plant, the author demonstrated that under these specific operating conditions, the best economic performance is obtained when using the temperature of the geothermal well at the end of its exploitation (i.e., the lowest temperature) instead of using the temperature at the beginning. Didit et al [21] assumed a constant injection mass flow rate and used a curve fitting of the analytical expression for the reservoir temperature presented in [22].…”
