TL;DR: In this article, a long-term hydrogen-based scenario of the global energy system is described in qualitative and quantitative terms, illustrating the key role of hydrogen in a longterm transition toward a clean and sustainable energy future.
756 citations
TL;DR: In this paper, generalized crack initiation and crack damage thresholds of rock masses are proposed, where the crack initiation threshold is defined by σ1−σ3=A σcm and the crack damage threshold is determined by π 1−σ 3=B σ cm for jointed rock masses, where B is the uniaxial compressive strength of the rock masses and A is the material constant.

TL;DR: In this article, a new type fault locator has been developed, that calculates the reactance of a faulty line, with a micro-processor, using the one-terminal voltage and current data of the transmission line.
Abstract: A new type fault locator has been developed, that calculates the reactance of a faulty line, with a micro-processor, using the one-terminal voltage and current data of the transmission line. Errors caused by various factors such as load flow, fault resistance, and the unsymmetrical arrangement of the transmission line, are automatically corrected. The equipment is now under field test, and during the nine months of the field test, the equipment has operated satisfactorily.

TL;DR: In this article, a quantitative approach to assist in the use of the Geological Strength Index (GSI) system is presented, which is built on the linkage between descriptive geological terms and measurable field parameters such as joint spacing and joint roughness.

TL;DR: In this paper, the authors conducted a tsunami survey along a 2000 km stretch of the Japanese coast from about 50 to 200 km north of Sendai, the narrow bays focused the tsunami waves, generating the largest inundation heights and run-ups.
Abstract: [1] At 14:46 local time on March 11, 2011, a magnitude 9.0 earthquake occurred off the coast of northeast Japan. This earthquake generated a tsunami that struck Japan as well as various locations around the Pacific Ocean. With the participation of researchers from throughout Japan, joint research groups conducted a tsunami survey along a 2000 km stretch of the Japanese coast. More than 5300 locations have been surveyed to date, generating the largest tsunami survey dataset in the world. On the Sendai Plain, the maximum inundation height was 19.5 m, and the tsunami bore propagated more than 5 km inland. Along the ria coast from about 50 to 200 km north of Sendai, the narrow bays focused the tsunami waves, generating the largest inundation heights and run-ups. The survey data clearly show a regional dependence of tsunami characteristics.
