Understanding human–work domain interaction: Implications for the design of a corporate digital library
Authors: Xie Hong (Iris) 
Published: November 2005

AbstractThe author applies the cognitive work analysis (CWA) approach to investigate human–work interaction in a corporate setting. This study reports the analysis of data collected from a Web survey, diaries, and telephone interviews. The results present characterizations of actors and the work domain; three dimensions for each of the four interactive activities involved in the human–work interaction and their relationships are identified. An enhanced model and its implications for the development of a corporate digital library are discussed.

Synthesis and Investigations of the Crystal Structure of aDinuclear Diazadiene Molybdenum Oxo‐Imido Complex with a Unique N3Mo(μ‐O)2MoN3 Core
Authors: Merkoulov Alexei , Harms Klaus , Sundermeyer Jörg 
Published: November 2005

AbstractLigand metathesis of the diimido and dioxo precursor complexes [Mo(X)2Cl2(DME)] (X = O, NtBu) leads to the mixed oxo‐imido derivative [Mo(NtBu)(O)Cl2(DME)] (1). By treatment with Li2DAD (DAD = 1,4‐di‐tert‐butyl‐1,4‐diazabuta‐1,3‐diene), 1 is converted into the complex [Mo(NtBu)(O)(DAD)]2 (2). The crystal structure determination on a nonmerohedral twin of 2 reveals a dinuclear molecular structure with nearly symmetrical bridging oxygen atoms. The smaller oxo ligand tends to be a better bridging functionality than the imido ligand; the unprecedented N3Mo(μ‐O)2MoN3 configuration is favored over a ON2Mo(μ‐N)2MoN2O core. Compared to other known molybdenum DAD complexes, 2 reveals some degree of pyramidalization at the nitrogen atoms of the DAD ligand. In accord with the Mo–N, N–C, and C–C bond lengths, complex 2 is best described as an ene‐diamido complex of formally six‐valent molybdenum. (© Wiley‐VCH Verlag GmbH & Co.

AbstractThe compound [CoCu(opba)(DMSO)3] (1) [opba = ortho‐phenylenebis(oxamato)] has been synthesized and characterized. Its crystal structure has been analyzed by X‐ray diffraction techniques at 100 and 298 K. A structural phase‐transition has been detected at around 150 K. An orthorhombic crystalline system is found at both temperatures, with very similar unit‐cell dimensions. At room temperature 1 crystallizes in the Pnam space group (α‐1 phase), with a = 7.6712(2), b = 14.8003(3), c = 21.0028(5) Å, and Z = 4, whereas at low temperature it crystallizes in the Pna21 space group (β‐1 phase), with a = 7.3530(2), b = 14.5928(4), c = 21.0510(7) Å, and Z = 4. Both crystalline phases consist of linearly ordered bimetallic chains with the [Cu(opba)]2– units tied by CoII ions to form a one‐dimensional system. The DMSO molecules in α‐1, which are coordinated to either CuII or CoII, are disordered. At low temperature, a small reorganization of the CuII and CoII environments is observed. The origin of this phase transition, which is completely reversible, is the modification of the crystalline packing with the temperature. Linear birefringence measurements were done on single crystals in the 100–300 K temperature range. Around 150 K, the linear birefringence curve shows an inflexion that is interpreted as being related to the conversion of α‐1 into β‐1. Both dc and ac magnetic measurements were performed on the polycrystalline sample. The results reveal a one‐dimensional ferrimagnetic behavior. Single crystal optical characterization at room temperature shows that 1 presents a very strong dichroism superposed on the linear birefringence. (© Wiley‐VCH Verlag GmbH & Co.

AbstractThe Mo36‐polyoxometalate [Mo36O108(NO)4(H2O)16]12– reacts with Ln3+ to give crystalline solids with 1D, 2D, and 3D polymeric frameworks, depending on the size of Ln3+ and the reaction conditions. Reaction of LaCl3 with (NH4)12[Mo36O108(NO)4(H2O)16] gives (H3O)2[{La(H2O)5}2{La(H2O)6}{La(H2O)5Cl}{Mo36(NO)4O108(H2O)16}]Cl·21H2O (1), inwhose structure the La3+ cations and the polyoxometalate anions are united in a 3D framework, whereas NdCl3 and SmCl3 give [{Ln(H2O)6}4{Ln(H2O)4}{Mo36(NO)4O108(H2O)16}]Cl3·nH2O [Ln = Nd, n = 24 (2); Ln = Sm, n = 21 (3)], which have 2D frameworks. Under different conditions, large Ln3+ ions (La–Nd) give the one‐dimensional coordination polymers [{Ln(H2O)6}2{Ln(H2O)7}2{Mo36(NO)4O108(H2O)16}]·nH2O [Ln = La, n = 29 (4); Ln = Ce, n = 41 (5), Ln = Pr; n = 40 (6), Ln = Nd, n = 36 (7)], whereas reaction with Gd(NO3)3 gives [{Gd(H2O)5}4{Mo36(NO)4O108(H2O)16}]·34H2O (8), which has a unique 2D layered structure. Smaller Ln3+ ions (Tb–Lu) give isostructural 1D chain coordination polymers (H3O)3[{Ln(H2O)6}2{Ln(H2O)4}{Mo36(NO)4O108(H2O)16}]·nH2O [Ln = Tb, n = 42 (9); Ln = Dy, n = 43 (10), Ln = Ho, n = 46 (11), Ln = Er, n = 50 (12); Ln = Yb, n = 56 (13); Ln = Lu, n = 31 (14)]. The first coordination polymer based on [Mo36O112(H2O)16]8–, namely (H3O)2[{Nd(H2O)5}2{Mo36O112(H2O)16}]·40H2O (15), was prepared from MoO42–, NH2OH, and Nd3+. It has a 2D layered structure. All these compounds are obtained in moderate to high yields (35–93 %), and were characterized by elemental analysis, IR spectroscopy, and single‐crystal X‐ray structural analysis. Direct coordination of Ln3+ to the oxygen atoms of terminal cis‐MoO22+ groups is responsible for the formation of these polymeric frameworks. The coordination numbers of Ln3+ change from 9 (La–Sm) to 8 (Gd–Lu). (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)

AbstractThe novel heterobimetallic sodium‐bismuth‐oxo clusters [Bi2Na4O(OSiMe3)8] (1), [Bi10Na5O7(OH)6(OSiMe3)15]·1.5C7H8 (2·1.5C7H8), [Bi15Na3O18(OSiMe3)12]·C7H8 (3·C7H8) and [Bi14Na8O18(OSiMe3)14(THF)4]·C6H6 (4·C6H6) were prepared starting from BiCl3 and NaOSiMe3. Compound 1 crystallises in the trigonal space group R$\bar {3}$c with the lattice constants a = 12.8844(3) Å and c = 54.6565(3) Å, compound 2·1.5C7H8 crystallises in the triclinic space group P$\bar {1}$ with the lattice constants a = 15.0377(2) Å, b = 16.0373(2) Å, c = 27.8967(5) Å, α = 87.1321(6)°, β = 86.6530(7)° and γ = 63.6617(6)°, compound 3·C7H8 crystallises in the monoclinic space group C2/c with the lattice constants a = 54.311(11), b = 19.846(4), c = 22.885(5) Å and β = 112.32(3)°, and compound 4·C6H6 crystallises in the trigonal space group R$\bar {3}$ with the lattice constants a = 15.9786(4) Å and c = 46.8329(17) Å. The formation of M–O–M bonds results from both partial hydrolysis followed by condensation as well as from elimination of Me3SiOSiMe3 from M–OSiMe3 groups. The hexanuclear metal‐oxo silanolate 1 is more conveniently synthesised by the addition of NaOSiMe3 to a toluene solution of in situ‐prepared [Bi(OSiMe3)3]. The metal‐oxo(hydroxo) silanolates differ significantly in composition, but show similar building units. Thermal decomposition of the metal‐oxo silanolates in the solid state gave heterogeneous decomposition products containing bismuth silicates. (© Wiley‐VCH Verlag GmbH & Co.

AbstractPyrazine‐2,3,5,6‐tetracarboxylic acid (ptcH4) reacts with Co(NO3)2·6H2O in 1:2 molar ratio in aqueous pyridine (py) at room temperature to form a coordination polymer with the empirical formula, {[Co2(ptc)·(py)2·4H2O]·4H2O}n, (1). The structure consists of 2D sheets of metal‐organic frameworks and infinite chains of cyclic water hexamers that join these sheets to form an overall 3D structure.

These network structures are characterized by X‐ray crystallography, powder X‐ray diffraction, infrared and thermal gravimetric analyses.

Evaluation of a coupled solution approach for fluid flow calculations in body‐fitted co‐ordinates
Authors: Karki K. C. , Mongia H. C. 
Published: November 2005

AbstractAn investigation has been conducted to study the performance of a coupled solution approach for solving the fluid flow equations in body‐fitted co‐ordinates using a covariant velocity formulation. The set of discrete equations is solved using a sparse matrix variant of LU decomposition. A series of test problems have been considered to study the effects of Reynolds number, mesh skewness and grid size on the convergence rate. The coupled solution approach has been compared with a state‐of‐the‐art sequential approach. The results indicate that the coupled technique is faster by a factor of about two for reasonable grids. For severely non‐orthogonal grids the performance of the coupled solution approach deteriorates considerably.
Taylor–least‐squares finite element for two‐dimensional advection‐dominated unsteady advection–diffusion problems
Authors: Park Nam‐Sik , Liggett James A. 
Published: November 2005

AbstractA new finite element method, the Taylor–least‐squares, is proposed to approximate the advection‐dominated unsteady advection–diffusion equation. The new scheme is a direct generalization of the Taylor–Galerkin and least‐squares finite element methods. Higher‐order spatial derivatives in the new formulation necessitate higher‐degree polynomials. Hermite cubic shape functions are used. Extensive comparisons with other methods in one dimension proved that the new scheme is a step forward in modelling this difficult problem. The method offers straightforward generalizations to higher dimensions without losing the accuracy demonstrated in one dimension, i.e. the method preserves the important property of the Taylor–Galerkin scheme of being free of numerical crosswind diffusion. Several numerical experiments were made in two dimensions and excellent results were obtained from the representative experiments.
Fourier analysis of the Eulerian–Lagrangian least squares collocation method
Authors: Bentley L. R. , Aldama A. , Pinder G. F. 
Published: November 2005

AbstractA Fourier analysis was performed in order to study the numerical characteristics of the effective Eulerian–Lagrangian least squares collocation (ELLESCO) method. As applied to the transport equation, ELLESCO requires a C1‐continuous trial space and has two degrees of freedom per node. Two coupled discrete equations are generated for a typical interior node for a one‐dimensional problem. Each degree of freedom is expanded separately in a Fourier series and is substituted into the discrete equations to form a homogeneous matrix equation. The required singularity of the system matrix leads to a ‘physical’ amplification factor that characterizes the numerical propagation of the initial conditions and a ‘computational’ one that can affect stability.Unconditional stability for time‐stepping weights greater than or equal to 0‐5 is demonstrated. With advection only, ELLESCO accurately propagates spatial wavelengths down to 2Δx. As the dimensionless dispersion number becomes large, implicit formulations accurately propagate the phase, but the higher‐wave‐number components are underdamped. At large dispersion numbers, phase errors combined with underdamping cause oscillations in Crank–Nicolson solutions. These effects lead to limits on the temporal discretization when dispersion is present. Increases in the number of collocation points per element improve the spectral behaviour of ELLESCO.
GSMAC finite element method for unsteady incompressible Navier–Stokes equations at high reynolds numbers
Authors: Tanahashi T. , Okanaga H. , Saito T. 
Published: November 2005

AbstractA new finite element technique is developed for predicting the velocity and the pressure in transient incompressible viscous fluid flows at high Reynolds numbers. The new method is based on the generalized and simplified marker‐and‐cell method (GSMAC) and has two characteristics: one is an application of the Bernoulli function and the implicit pressure solution algorithm to the explicit fractional time step method; the other is a high‐order flux calculation to prevent the pressure field from oscillating. Two examples, driven cavity flows at high Reynolds numbers and vortex shedding behind a circular cylinder, are presented. Satisfactory agreement with experiment is demonstrated.
On the quality of viscoelastic flow solutions: An adaptive refinement study of a Newtonian and a maxwell fluid
Authors: Rao Rekha R. , Finlayson Bruce A. 
Published: November 2005

AbstractLittle adaptive finite element work has been done in the area of viscoelastic flow in complex geometries. In this paper an adaptive finite element mesh refinement study is carried out on a Newtonian fluid and a Maxwell fluid in an axisymmetric 4:1 contraction. The error indicator used for the refinement is the local norm of the residual in an element. For the Newtonian fluid, steady improvement with refinement is seen, though this is not the case for the Maxwell fluid, which never achieves a solution of good quality.
Compressible viscous flow calculations using compatible finite element approximations
Authors: Bristeau M. O. , Glowinski R. , Dutto L. , Périaux J. , Rogé G. 
Published: November 2005

AbstractWe discuss in this paper the numerical simulation of compressible viscous flows by a combination of finite element methods for the space approximation, an implicit second‐order multistep scheme for the time discretization and GMRES iterative methods for solving the non‐linear problems encountered at each time step. Numerical results corresponding to flows around aerofoils and aerospace vehicles illustrate the possibilities of these methods.
Godunov–mixed methods for immiscible displacement
Authors: Dawson Clint N. 
Published: November 2005

AbstractThe immiscible displacement problem in reservoir engineering can be formulated as a system of partial differential equations which includes an elliptic pressure–velocity equation and a degenerate parabolic saturation equation. We apply a sequential numerical scheme to this problem where time splitting is used to solve the saturation equation. In this procedure one approximates advection by a higher‐order Godunov method and diffusion by a mixed finite element method. Numerical results for this scheme applied to gas–oil centrifuge experiments are given.
