Show moreEffective use of the Requirement gathering is our greatest and most critical role. We need to communicate with stakeholders to make the best of it. The techniques mentioned here are mixed and for each project, the mix shall be different. This technique for gathering requirements is perhaps the most common way to obtain requirements from all the required techniques. This article also looks at how to run a Delphi session, Creating Affinity Diagram & Mind maps. Show less

Show morePhotograph of the Armor Research Foundation's Antarctic Snow Cruiser on a crowded street (location unknown) during the trip between Chicago and the Boston Army Wharf, the Snow Cruiser's departure point for Antarctica. The Snow Cruiser was designed by Armor Research Foundation Scientific Director Thomas C. Poulter, constructed by ARF, and taken on Richard Byrd's third Antarctic expedition. This photograph originally appeared in the December 1939 issue of the Armor Engineer and Alumnus. Photographer unknown. Show less

binary. Its main contributions are (1) a birational parametrization for every such HMM, with an
explicit inverse for recovering the hidden parameters in terms of observables, (2) a semialgebraic
model membership test for every such HMM, and (3) minimal dening equations for the 4-node
fully binary model, comprising 21 quadrics and 29 cubics, which were computed using Grobner
bases in the cumulant coordinates of Sturmfels and Zwiernik. The new model parameters in (1) are
rationally identiable in the sense of Sullivant, Garcia-Puente, and Spielvogel, and each model's
Zariski closure is therefore a rational projective variety of dimension 5. Grobner basis computations
for the model and its graph are found to be considerably faster using these parameters. In the
case of two hidden states, item (2) supersedes a previous algorithm of Schonhuth which is only
generically dened, and the dening equations (3) yield new invariants for HMMs of all lengths
4. Such invariants have been used successfully in model selection problems in phylogenetics, and
one can hope for similar applications in the case of HMMs. Show less
