#### Variational Stokes: A Unified Pressure-viscosity Solver for Accurate Viscous Liquids

(Association for Computing Machinery, 2017-07-20)

We propose a novel unsteady Stokes solver for coupled viscous and pressure forces in grid-based liquid animation which yields greater accuracy and visual realism than previously achieved. Modern fluid simulators treat ...

#### Theory Of Atomata

(Elsevier, 2014-06-19)

We show that every regular language defines a unique nondeterministic finite automaton (NFA), which we call "atomaton", whose states are the "atoms" of the language, that is, non-empty intersections of complemented or ...

#### Syntactic Complexity Of R- And J-Trivial Regular Languages

(World Scientific Publishing, 2014-11-01)

The syntactic complexity of a subclass of the class of regular languages is the maximal cardinality of syntactic semigroups of languages in that class, taken as a function of the state complexity n of these languages. We ...

#### Quotient Complexity Of Closed Languages

(Springer, 2014-02-01)

A language L is prefix-closed if, whenever a word w is in L, then every prefix of w is also in L. We define suffix-, factor-, and subword-closed languages in an analogous way, where by factor we mean contiguous subsequence, ...

#### On The Complexity Of The Evaluation Of Transient Extensions Of Boolean Functions

(World Scientific Publishing, 2012-01-01)

Transient algebra is a multi-valued algebra for hazard detection in gate circuits. Sequences of alternating 0's and 1's, called transients, represent signal values, and gates are modeled by extensions of boolean functions ...

#### Quotient Complexity Of Star-Free Languages

(World Scientific Publishing, 2012-09-01)

The quotient complexity, also known as state complexity, of a regular language is the number of distinct left quotients of the language. The quotient complexity of an operation is the maximal quotient complexity of the ...

#### Time-consistent mean–variance portfolio optimization: A numerical impulse control approach

(Elsevier, 2018-11-01)

We investigate the time-consistent mean–variance (MV) portfolio optimization problem, popular in investment–reinsurance and investment-only applications, under a realistic context that involves the simultaneous application ...

#### Complexity of Right-Ideal, Prefix-Closed, and Prefix-Free Regular Languages

(Institute of Informatics: University of Szeged, 2017)

A language L over an alphabet E is prefix-convex if, for any words x, y, z is an element of Sigma*, whenever x and xyz are in L, then so is xy. Prefix-convex languages include right-ideal, prefix-closed, and prefix-free ...

#### Quotient Complexity of Bifix-, Factor-, and Subword-Free Regular Language

(Institute of Informatics: University of Szeged, 2014)

A language $L$ is prefix-free if whenever words $u$ and $v$ are in $L$ and $u$ is a prefix of $v$, then $u=v$. Suffix-, factor-, and subword-free languages are defined similarly, where by ``subword" we mean ``subsequence", ...

#### Quotient Complexities of Atoms in Regular Ideal Languages

(Institute of Informatics: University of Szeged, 2015)

A (left) quotient of a language L by a word w is the language w(-1) L = {x vertical bar wx is an element of L}. The quotient complexity of a regular language L is the number of quotients of L; it is equal to the state ...
