the mere assertion of constancy of the total energy, kinetic and potential, of a material system is insufficient of itself to determine the actual motion of systems with more than one degree of freedom, and, moreover, cannot be applied to find the passive reactions arising from constraints.
Problems arising from constraints on parameters are well known, and there are a number of solutions in the statistics literature.
Temporal mismatch between the Townsend score (1991), survey data (1998) and benefits data (2001) is a further limitation, arising from constraints of data availability.
Perec lived for the creative opportunities that arise from constraint — this is the author who famously wrote a novel without using the letter "e" — and he approached dream writing as a creative exercise in which language itself was the constraint.
Selection in protein evolution, on the other hand, also depends on functional constraints, on other stability constraints, as for instance secondary structure, and on constraints arising from protein dynamics.
Since, in practice, each airport has its own physical architecture, there have been arisen many constraints mainly concerning airplane types and parking lots in this step.
Department chairs / managers and center directors may find the need to revise these guidelines and/or prohibit pets in certain areas if circumstances within departments / centers arise (space constraints, employees with allergies, etc.).
Absence of DNA curvature-related sequence periodicity in phages could arise from constraints associated with DNA packaging in the viral capsid.
We present MC, Model and Constraint Consistency Checker, a computational tool that can be used for two purposes: (a) identifying potential connectivity and topological issues for a given stoichiometric matrix, S, and (b) flagging issues that arise during constraint-based optimization.
The figure shows the "Plan 7" model used by HMMer, the name of which arises from constraints in the transition kernel disallowing all but seven transitions out of the three states corresponding to each profile position.
