Reduced-order mass weighted proper orthogonal decomposition (RMPOD), smooth orthogonal decomposition (SOD), and state variable modal decomposition (SVMD) are used to extract modal parameters from a nonuniform experimental beam. The beam was sensed by accelerometers. Accelerometer signals were integrated and passed through a high-pass filter to obtain velocities and displacements, all of which w...

this paper presents new sensitivity-based methods for detection of structural damage using incomplete noisy modal data. these methods are based on the first-order derivative of modal parameters. changes of natural frequency do not usually provide spatial information on the structural damage. they are also not sensitive to the local damage. in this paper, a new sensitivity function is proposed u...

conclusions although carbohydrate fermentation patterns specified these three isolates as b. infantis, b. bifidum, and b. longum, the molecular results did not confirm b. longum, which is still also controversial in the literature. overall, our results demonstrated that kashk-e zard is a rich potential source of probiotic bacteria and further investigations should be undertaken. results twelve ...

density of rhizobium population in faba bean (vicia faba l.) fields of wollo area (asketema, gashana, kotem, major and sekota) northern ethiopia was studied. the highest population of rhizobia was found at major and the least at sekota regions. the native rhizobial strains isolated from the northern parts of the country tolerated a higher salt concentration (5% nacl) than the exotic rhizobial s...

a new system is presented for the generation ofrecombinant bacillus subtilis strains without antibioticmarkers. this system is based on two plasmids constructed in escherichia coli. the first plasmid phm30contains an incomplete hisi gene, the last gene in thehistidine biosynthesis operon of b. subtilis and part ofthe genes yvca and yvcb of unkown function flankinghisi at the 3´-end. the spectin...

Under German law, federal ministries are responsible for preparing legislation, while federal states (Länder) are responsible for applying the legislation. The author describes the system, contrasting it with the situation in former East Germany, where preparation and application of legislation were controlled centrally. The author also describes the various inland water fisheries Acts and regu...

A number of recombinant inbred mouse strains (currently 48) have been developed from the strains A/J and C57BL/6J. These strains are likely to become an excellent probe in the study of genetic mechanisms underlying host resistance to infections and tumors.

In recent years, a tight connection has emerged between modal logic on the one hand and coalgebras, understood as generic transition systems, on the other hand. Here, we prove that (finitary) coalgebraic modal logic has the finite model property. This fact not only reproves known completeness results for coalgebraic modal logic, which we push further by establishing that every coalgebraic modal...

We reexamine the modal-calculus in the light of some classical theory of Boolean algebras and recent results on duality theory for a modal logic with xed points. We propose interpreting formulas into a eld of subsets of states instead of the full power set lattice used by Kozen. Under this interpretation we relate image compact modal frames with Scott continuity of the box modality, m-saturated...
