Let G be a finite subgroup of a symplectic group Sp2d(Ql). Despite the fact ([3]) that G can fail to be conjugate in GL2d(Ql) to a subgroup of Sp2d(Zl), we prove that it can nevertheless be embedded in Sp2d(Fl) in such a way that the characteristic polynomials are preserved (mod l), as long as l > 3. We start with the following “rigidity” result, which is in the spirit of similar results by Min...

An input and output queueing ATM switch model with a backpressure (BP) mode and a queue loss (QL) mode to decrease the system delay and the cell loss probability under nonuniform traffic is proposed. In the proposed model, the QL mode is adopted if the size of the backpressure exceeds the threshold. We consider a synchronous system with Bernoulli arrivals under hot-spot traffic that consists of...

Approximate Mean Value Analysis (MVA) is a popular technique for analyzing queueing networks because of the efficiency and accuracy that it affords. In this paper, we present a new software package, called the Improved Approximate Mean Value Analysis Library (IAMVAL), which can be easily integrated into existing commercial and research queueing network analysis packages. The IAMVAL packages inc...

where a = ~H/kBT, kB i~ Boltzmann's constant, T is te~­ perature, and ~ is def1ned as before. The total stat1c structure factor S(QL,QR,a) is therefore the single nilrticle structllre factor, \~eighted by th" angular dis­ tribution function, integrated over all angles: S(QL,QR,a) = Nf p(~,a) Ssp(QL,QR,~) d~ (3) Light scattering was used to determine both ~he. average length8 and magnetic moment...

Motivated by a recent paper of Louko and Molgado, we consider a simple system with a single classical constraint R(q) = 0. If ql denotes a generic solution to R(q) = 0, our examples include cases where R(ql) 6= 0 (regular constraint) and R(ql) = 0 (irregular constraint) of varying order as well as the case where R(q) = 0 for an interval, such as a ≤ q ≤ b. Quantization of irregular constraints ...

XML is emerging as one of the dominant data formats for data processing on the Internet. To query XML data, query languages like XQL, Lorel, XML-QL, or XML-GL have been proposed. In this paper, we study how XML data can be stored and queried using a standard relational database system. For this purpose, we present alternative mapping schemes to store XML data in a relational database and discus...

S(u) denotes the interfacial area associated with the surfaces upon which u jumps, and G(x, y) denotes the Green’s function for − on QL with Neumann boundary conditions. The variational problem consists of competing short-range (S(u)) and long-range (the nonlocal Green’s function term) contributions. The former term is attractive, favoring large domains of pure phases with boundaries of minimal...

In the last years, many research directed for concurrency control mechanism, scheduling policy and query language in real-time database are being done. This paper presents an extensions of standard query language (SQL), called SQL-99. SQL-99 includes oriented-object functionalities. The query language for real-time database (QL-RTDB) to provide support the real-time requirements imposed the bot...

We study quadratic forms that can occur as trace forms qL/K of Galois field extensions L/K, under the assumption that K contains a primitive 4th root of unity. M. Epkenhans conjectured that qL/K is always a scaled Pfister form. We prove this conjecture and classify the finite groups G which admit a G-Galois extension L/K with a nonhyperbolic trace form. We also give several applications of thes...

We study the effect of the neutralino polarization in a squark cascade decay q̃ → qχ̃ 2 → ql l̃ → ql l̃ → qllχ̃ 1 . Charge asymmetry in the lepton-jet invariant mass distribution appears depending on the chirality structure of the sfermion-fermion-neutralino coupling. With use of the Monte Carlo simulation, we show that the asymmetry is measurable in LHC. We also show that the distribution of the ch...
