The challenges of information systems (IS) development have changed significantly in the past 15 years. From a situation where the main problem was to build stable systems based on a requirements specification, the IS project manager now faces challenges of integration; for example: how to integrate a new information system into large existing information infrastructures and unstable business p...

Spinach leaf (Spinacia oleracea L. var. Kyoho) protoplasts sustain protein-synthesizing activity as measured by the incorporation of [(14)C]-leucine into the protein fraction both in the light and in the dark. By the immunoprecipitation of ribulose-1,5-bisphosphate (RuP(2)) carboxylase with rabbit antibody raised against the purified spinach enzyme preparation, it was found that approximately 7...

Transitioning from waterfall to agile processes can be difficult especially for organizations lacking toplevel management support. To explore this topic, we collected qualitative and quantitative data about three projects at a government agency transitioning from a waterfall process to the IBM Rational Unified Process. The results of our analysis of this data identify some of the challenges org...

Dye-sensitized photoelectrochemical cells were prepared with popular ruthenium sensitizer (RuP) and catalyst (RuCAT) coadsorbed on mesoporous titania. The studied in 0.1 M Na2SO4(aq) by spectroscopic methods, including femtosecond transient absorption spectroscopy. formation of RuCAT dimer can be observed the naked eye due to change color from dark-red green. displays a characteristic feature λ...

The importance of producing a certi cate of unsatis ability is increasingly recognized for high performance propositional satis ability solvers. The leading solvers develop a con ict graph as the basis for deriving (or \learning") new clauses. Extracting a resolution derivation from the con ict graph is theoretically straightforward, but resolution proofs can be extremely long. Several other ce...

Altought widely used and recognized in the scientific community, the i* framework has, until now, failed to impose itself into enterprise practices. There are many ways that can be followed to favor industry-adoption. Among them, we believe that an integration into the (Rational) Unified Process, which already includes business modeling as a preliminary step in software development and furnishe...

Learning Management System (LMS) development has become a high priority project for educational institutions and organizations, as it provides the virtual environment for online education. Acquiring and deploying a LMS is a difficult task that involves risks related with costs and time. The goal of this research in progress is to introduce an extension in the Rational Unified Process (RUP) in o...

The foundation of Model Driven Architecture (MDA) approach is creation of models. MDA life cycle begins from Computation Independent Model (CIM) and ends with code. Object Management Group (OMG) explains various models and their relations, but it does not specify clearly how to create these models and which models to use for representation them. In this paper, we focus on CIM level. CIM is the ...

Considerable progress has been made over the last 30 years in the United States to develop systems that describe protein requirements and protein adequacy of diets for dairy cows. Ration formulation systems have moved from balancing diets for crude protein (CP) and digestible protein to the use of nutritional models (e.g., NRC, 2001; CNCPS, CPM-Dairy, and Amino Cow) that recognize that the cow ...
