The effect of dissolved gas on the reversibility of a Li/Li electrode in an ionic liquid electrolyte was investigated. Lithium metal is a potential anode in lithium batteries. The ionic liquid electrolyte was saturated with argon, nitrogen, oxygen, air, or carbon dioxide and the coulombic efficiency for the reduction and reoxidation of lithium metal was measured. Secondary ion mass spectroscopy...

The SEI has been involved with the development and analysis of software process models for several years. As part of the ongoing process of technology evolution, a study has been undertaken to experimentally implement a set of proposed improvements to the process modeling techniques used by the SEI, and to evaluate the results of that experimentation. As a result of that study, a number of modi...

Although the capability maturity model has become an accepted basis for software process improvement in software organizations, its diffusion in IS organizations continues to be slow. This paper describes the experience of piloting the Software Engineering Institute (SEI) process improvement with six different information systems (IS) groups. It brings out the perceptions and reactions of IS de...

The tangram and Sei Shōnagon Chie no Ita are popular dissection puzzles consisting of seven pieces. Each puzzle can be formed by identifying edges from sixteen identical right isosceles triangles. It is known that the tangram can form 13 convex polygons. We show that Sei Shōnagon Chie no Ita can form 16 convex polygons, propose a new puzzle that can form 19, no 7 piece puzzle can form 20, and 1...

Sei whales are the least well known acoustically of all the rorquals, with only two brief descriptions of their calls previously reported. Recordings of low-frequency tonal and frequency swept calls were made near a group of four or five sei whales in waters west of the Antarctic Peninsula on 19 February 2003. These whales also produced broadband sounds which can be described as growls or whoos...

To study the impact of media coverage on spread and control of infectious diseases, we use a susceptible-exposed-infective (SEI) model, including individuals' behavior changes in their contacts due to the influences of media coverage, and fully investigate the model dynamics. We define the basic reproductive number ?0 for the model, and show that the modeled disease dies out regardless of initi...
