In this paper, a new approach for adaptive linearizing control of continuous fermentations with immobilized yeasts Saccharomyces cerevisiae BO 213 was proposed. Three fermentations with three different procedures of cells immobilization were investigated. The switching from batch to continuous mode of cultivation was realized automatically in time when the ethanol production rate reaches its ma...

The P1 discretization of the Laplace operator on a triangulated polyhedral surface is related to geometric properties of the surface. This paper studies extremum problems for eigenvalues of the P1 discretization of the Laplace operator. Among all triangles, an equilateral triangle has the maximal first positive eigenvalue. Among all cyclic quadrilateral, a square has the maximal first positive ...

Previous implementations of the Aq algorithm have used rule optimisation search strategies to attempt to develop optimal classification procedures. These strategies involve generating successive characteristic descriptions each of which is individually of maximal value. This is contrasted with theory optimisation search strategies which, instead, generate successive complete classification proc...

Matang Mangrove Forest Reserve (MMFR) in Peninsular Malaysia is under systematic management since 1902 and still considered as the best managed mangrove forest in the world. The present study on silvimetrics assessed the ongoing MMFR forest management, which includes a first thinning after 15 years, a second thinning after 20 years and clear-felling of 30-year old forest blocks, for its efficie...

Working over an algebraically closed, complete, non-Archimedean, non-trivially valued eld of characteristic zero, we show that (i) any subanalytic subset of a one-dimensional semialgebraic set is semialgebraic; (ii) any one-dimensional sub-analytic set is semianalytic; and (iii) any subanalytic subset of a two-dimensional semianalytic set is semianalytic. x1. Introduction In this paper, K denot...

In environments with “diffuse” uncertainty, we study bidding behavior in auctions and double auctions. Our dynamics has a strong component of inertia but with a small probability, bids are modified in the direction of ex-post regrets. We apply stochastic stability to identify essentially a unique bid that will be used by each type in the long run. In the first-price auction, bidding half of one...

In wireless sensor networks, node failures occur frequently. The effects of these failures can be reduced by using aggregated values of small groups of sensors instead of the values of individual sensors. However, most existing works have focused on computing the aggregation of all the nodes without grouping. Only a few approaches proposed the processing of grouped aggregate queries. However, s...

A single principal interacts with several agents, offering them contracts. The crucial assumption of this paper is that the outside-option payoffs of the agents depend positively on how many “free agents” there are (these are agents who are not under contract). We study how such a principal, unwelcome though he may be, approaches the problem of contract provision to agents when coordination fai...

Definition 19. A generalized complex structure (GCS) on E is an integrable orthogonal complex structure J : E E, i.e. a map s.t. → • �JA, JB� = �A,B� • L = Ker (J − i1) Note. 1. �JA,B� = �JA, JB� = −�A, JB�, and thus �J·, ·� is a symplectic struction on E compatible with �, �. 2. L is maximal isotropic and so is L, and thus E = L ⊕ L = L ⊕ L∗ and we get a Lie bialgebroid. 3. V must be even dime...

Our aim here is to give a fairly self-contained exposition of some basic facts about the Iwahori-Hecke algebra H of a split p-adic group, including Bernstein’s presentation and description of the center, Macdonald’s formula, the CasselmanShalika formula, and the Kato-Lusztig formula. There are no new results here, and the same is essentially true of the proofs. We have been strongly influenced ...
