Applications of internet technology for requirements elicitation
During the Requirements Elicitation part of a project various stakeholders need to be able to communicate their requirements to the developers, and the developers need to be able communicate their understanding back to the stakeholders. Communication between the various members of the project is the key factor during the Requirements Elicitation part of a project. Easing communications between stakeholders and developers makes the process of eliciting requirement easier, leading to better requirements specification and eventually a better product.
The Requirements Elicitation Process through Internet (REPI) web site has been designed and implemented to explore this idea. The prototype version of REPI guides project members through the elicitation phase using the Software Engineering Institute\u27s framework for Requirements Elicitation. The REPI web site forces stakeholders to explicitly describe the requirements and encourage early discussion between stakeholders and developers. This decreases the likelihood of misunderstood requirements, leading to better requirements specification
ChemTextMiner: An open source tool kit for mining medical literature abstracts
Text mining involves recognizing patterns from a wealth of information hidden latent in unstructured text and deducing explicit relationships among data entities by using data mining tools. Text mining of Biomedical literature is essential for building biological network connecting genes, proteins, drugs, therapeutic categories, side effects etc. related to diseases of interest. We present an approach for textmining biomedical literature mostly in terms of not so obvious hidden relationships and build biological network applied for the textmining of important human diseases like MTB, Malaria, Alzheimer and Diabetes. The methods, tools and data used for building biological networks using a distributed computing environment previously used for ChemXtreme[1] and ChemStar[2] applications are also described
Coherent bremsstrahlung and GDR width from 252Cf cold fission
The energy spectrum of the high energy gamma-rays in coincidence with the
prompt gamma rays has been measured for the spontaneous fission of 252Cf. The
nucleus-nucleus coherent bremsstrahlung of the accelerating fission fragments
is observed and the result has been substantiated with a theoretical
calculation based on the coulomb acceleration model. The width of the giant
dipole resonance (GDR) decay from the excited fission fragments has been
extracted for the first time and compared with the thermal shape fluctuation
model (TSFM) in the liquid drop formalism. The extracted GDR width is
significantly smaller than the predictions of TSFM.Comment: 12 pages, 3 figures, accepted for publication in Phys. Lett.
Scaling of the giant dipole resonance widths in hot rotating nuclei from the ground state values
The systematics of the giant dipole resonance (GDR) widths in hot and
rotating nuclei are studied in terms of temperature T, angular momentum J and
mass A. The different experimental data in the temperature range of 1 - 2 MeV
have been compared with the thermal shape fluctuation model (TSFM) in the
liquid drop formalism using a modified approach to estimate the average values
of T, J and A in the decay of the compound nucleus. The values of the ground
state GDR widths have been extracted from the TSFM parametrization in the
liquid drop limit for the corrected T, J and A for a given system and compared
with the corresponding available systematics of the experimentally measured
ground state GDR widths for a range of nuclei from A = 45 to 194. Amazingly,
the nature of the theoretically extracted ground state GDR widths matches
remarkably well, though 1.5 times smaller, with the experimentally measured
ground state GDR widths consistently over a wide range of nuclei.Comment: 15 pages, 4 figures, Accepted for publication in Physical Review
