into shock waves in the solar wind upstream of planets. Shortly after the oscillations, Voyager was in the new solar wind regime of heightened magnetic field. Everyone, including Krimigis, now agrees that this new regime is the heliosheath. Now that they are in it, researchers are eager to understand the heliosheath. They missed recording the actual passage through the shock because it occurred...

Statistically significant variations have been observed in the differential flux of ~27-MeV anomalous cosmic ray (ACR) oxygen, helium, and protons at the Voyager 1 spacecraft during 1998 and 1999 (at a helioradius of ~73 AU). The quasiperiodic variations are in phase, with oxygen and helium having periods near 151 days, while protons exhibit a period of ~146 days. The Voyager 1 ACRs vary by ~30...

The Voyager Interstellar Mission is exploring the interaction of the heliosphere with the local interstellar medium (LISM). Voyager 1 (V1) and Voyager 2 (V2) are both in the heliosheath, making the first in situ observations of the shocked solar wind beyond the termination shock (TS). The heliosheath extends to the heliopause; beyond the heliopause is the interstellar medium. The goal of the Vo...

introduction: nowadays , use of library software is a basic need for libraries and information centers. user interface is a part of computerized systems which is interacting to the user and it is an important factor in information searching process. this study aimed to compare librarian's satisfaction rate from library software interface in isfahan libraries in 2010. methods: this was a descrip...

Several companies riding the current wave of popularity of Java want to let you play in the mobile agent sandbox. Each claims that mobile agent technologies are going to change the way we live and work, and each wants to be the company that provides the breakthrough system we all end up using. What do these agent systems actually do and, more importantly, what distinguishes one agent system fro...
