The cyclopropenylidenyl carbene, c-(C)C3H2, should make for an excellent probe of unidentified infrared bands. It has a dipole moment of roughly 5.0 D making it easily detectable rotationally from the ground. Furthermore, it has vibrational frequencies computed here with proven and high-level quantum chemical methods that line up rather well with t...

The venerable Taylor series expansion is a workhorse of computational modeling within the computational and quantum chemistry disciplines. It provides a highly-descriptive means of constructing complicated functions reliably. However, higher-order implementations or broadly defined functions with large numbers of variables can create a significant...

The NS2 radical is a simple arrangement of atoms with a complex electronic structure. This molecule was first reported by Hassanzadeh and Andrew’s group [J. Am. Chem. Soc. 114, 83 (1992)] through Ar matrix isolation experiments. In the quarter century since this seminal work was published, almost nothing has been reported about nitrogen disulfide e...

Cassini has shown that CH2NH2 is likely present in relatively high abundance in Titan’s upper atmosphere. Relatively little is known about this molecule even though it contains the same number of electrons as ethylene, a molecule of significance to Titan’s chemistry. Any studies on CH2NH2 with application to Titan or its atmospheric chemistry will...

Commercial cloud computing (CCC) has the promise of an untold number of computing nodes available for the researcher as long as he or she has the financial means to absorb these costs and the administrative skills necessary to effectively utilize the resources. The key is finding how to maximize parallelization for a minimum of monetary and managem...

The SISE estimation model presents a novel alternative to PSP’s PROBE by combining expert judgment with empirical data to create reasonably accurate predictions.

The SISE estimation model presents a novel alternative to PSP's PROBE by combining expert judgment with empirical data to create reasonably accurate predictions. The model uses a simple, four-steps process in which a future activity is compared to a developer's completed tasks to identify two known effort values that define a prediction interval. I...

The growth of commercial cloud computing (CCC) as a viable means of computational infrastructure is largely unexplored for the purposes of quantum chemistry. In this work, the PSI4 suite of computational chemistry programs is installed on five different types of Amazon World Services CCC platforms. The performance for a set of electronically excite...

Micro Independent Software Vendors (microISVs) are small software businesses operated by entrepreneurs who build and sell shrink-wrapped, noncustom software. The microISV Research Alliance at Auburn University conducted a survey, identifying challenges associated with building and operating such businesses.

Truly viable software—mobile device apps, services, components—are being written by one-person teams, thus demonstrating the need for engineering discipline at the individual level. This article examines effort estimation for individuals and proposes a lightweight approach based on a synthesis of a number of concepts derived from existing team esti...
