We investigate the phononic energy transport properties of mesoscopic, suspended dielectric wires. The Landauer formula for the thermal conductance is derived and its universal aspects discussed. We then determine the variance of the energy current in the presence of a steady state current flow. In the final part, some initial results are presented concerning the nature of the temperature fluct...

LSA, a mathematical modeling technique, captures the essential relationships between text documents and word meaning, or semantics, the knowledge base which must be accessed to evaluate the quality of content. Several educational applications that employ LSA have been developed: (1) selecting the most appropriate text for learners with variable levels of background knowledge, (2) automatically ...

We present a precise formulation of a correspondence between information and thermodynamics that was first observed by Szilard, and later studied by Landauer. The correspondence identifies available free energy with relative entropy, and provides a dictionary between information and thermodynamics. We precisely state and prove this correspondence. The paper should be broadly accessible since we...

Thomas K. Landauer’s (1986) estimate of the capacity of normal human memory is deeply flawed. His estimate neither reflects the quantity of computational resources necessary for supporting a human-like memory, nor provides any constraint on a theory of such a memory. The roots of the problem lie in a m isunderstanding of the relationship of previous experience to intelligent behavior and theref...

Disordered T-shaped graphene nanodevice (TGN) was designed and studied in this paper. We demonstrated the intrinsic transport properties of the TGN by using Landauer approach. Knowing the transmission probability of an electron the current through the system is obtained using Landauer-Buttiker formalism. The effects of single disorder on conductance, current and on the transport length scales a...
