Spectrophotometry of Nova Cephei 1971

1971 , Volume , Issue Feb-1971

This impressive or CAÃ, system makes impressive contributions to the state of the art of CAI. It's a combination of field-proven hardware, a standard computer language, and well tested curricula. The first curriculum is an elementary mathematics drill and practice program. THAT A NEW PRODUCT SHOULD contribute substantially to the state of the art has long been a philosophical tenet at Hewlett-P...

Sloman 1971

This paper echoes, from a philosophical standpoint, the claim of McCarthy and Hayes that Philosophy and Artificial Intelligence have important relations. Philosophical problems about the use of 'intuition' in reasoning are related, via a concept of analogical representation, to problems in the simulation of perception, problem-solving and the generation of useful sets of possibilities in consid...

Planetary formation in the γ Cephei system

We numerically investigate under which conditions the planet detected at 2.1 AU of γ Cephei could form through the core-accretion scenario despite the perturbing presence of the highly eccentric companion star. We first show that the initial stage of runaway accretion of kilometer-sized planetesimals is possible within 2.5 AU from the central star only if large amounts of gas are present. In th...

Fluorescence Spectrophotometry

Fluorescence and phosphorescence are photon emission processes that occur during molecular relaxation from electronic excited states. These photonic processes involve transitions between electronic and vibrational states of polyatomic fluorescent molecules (fluorophores). The Jablonski diagram (Figure 1) offers a convenient representation of the excited state structure and the relevant transiti...
