Estimating dynamic copula dependence using intraday data
Authors: Grossmass Lidan , Poon Ser-Huang 
Published: December 2014

Abstract
We estimate the dynamic daily dependence between assets by applying the Semiparametric Copula-Based Multivariate Dynamic (SCOMDY) model on intraday data. Using tick data of three stock returns of the period before and during the credit crisis, we find that our dependence estimator better captures the steep increase in dependence during the onset of the crisis as compared to other commonly used time-varying copula methods. Like other high-frequency estimators, we find that the dependence estimator exhibits long memory and forecast it using a HAR model. We show that for out-of-sample forecasts, our dependence estimator performs better than the constant estimator and other commonly used time-varying copula dependence estimators.
Joseph, Jehoiachin, and Cyrus: On Book Endings, Exoduses and Exiles, and Yehudite/Judean Social Remembering
Authors: Wilson Ian Douglas 
Published: December 2014

In a recent ZAW article, Michael Chan argues that II Reg 25,27–30 alludes to Gen 40–41, and that this allusion provides a hermeneutical key for understanding the purpose of II Reg 25,27–30 in an Enneateuchal context: it points to an imminent exodus, a return from exile and a gathering of diaspora in the promised land. This article picks up where Chan left off, in order to flesh out some of the implications of his contribution. It argues that remembering exodus at the end of II Reg included hope, as Chan says, but also struggles and failure, punishment and death. Exodus is multivocal. Likewise, the end of II Reg contributes to a multivocal discourse concerning Davidic kingship, which included the end of Chronicles and prophetic literature. The diminution of Davidic kingship in II Reg 25,27–30 is balanced by other perspectives. The article concludes with an observation on the import of this multivocality for Yehudite social memory.Dans un article récent de la ZAW, Michael Chan tente d’établir que II Rois 25,27–30 fait allusion à Gen. 40–41, et que cette relation offre une clé herméneutique pour la compréhension de cette péricope dans le contexte de l’Ennéateuque: celle-ci renvoie à un exode imminent, un retour de l’exil et un rassemblement de la diaspora en terre promise. Cette étude prend le relais de celle de Chan, afin d’élucider certaines implications de sa contribution. L’A. soutient que l’évocation de l’Exode à la fin de II Rois inclut l’espérance (comme Chan le dit), mais aussi les combats et les échecs, la punition et la mort. L’exode est polysémique. De la même manière, la fin de II Rois contribue à un discours polyvalent sur la royauté de David, auquel participent aussi la fin des Chroniques et la littérature prophétique. L’amoindrissement de la royauté davidique en II Rois 25,27–30 est compensé par d’autres perspectives. On note enfin l’importance de cette polysémie pour la mémoire collective de Juda.In einem aktuellen ZAW-Aufsatz argumentiert Michael Chan, dass II Reg 25,27–30 auf Gen 40–41 anspielt, und dass diese Anspielung einen hermeneutischen Schlüssel für das Verständnis von II Reg 25,27–30 im Kontext des Enneateuch bereitstellt: Diese verweist auf einen nahe bevorstehenden Exodus, eine Rückkehr aus dem Exil und eine Sammlung der Diaspora im verheißenen Land. Dieser Artikel beginnt dort, wo Chan aufgehört hat, um einige der Konsequenzen seines Beitrags zu verdeutlichen. Es wird argumentiert, dass die Erinnerung an den Exodus am Ende von II Reg Hoffnung einschließt, wie Chan sagt, aber auch Kämpfe und Scheitern, Strafe und Tod. Der Exodus ist mehrdeutig. In ähnlicher Weise trägt das Ende von II Reg zu einem vielstimmigen Diskurs über das davidische Königtum bei, zu dem auch das Ende der Chronik und die prophetische Literatur gehören. Die Verkleinerung des davidischen Königtums in II Reg 25,27–30 wird durch andere Perspektiven ausbalanciert. Der Artikel schließt mit einer Beobachtung über die Bedeutung dieser Vielstimmigkeit für das kollektive Gedächtnis Jehuds.
The Dual Role of Historiography in Psalm 106: Justifying the Present Distress and Demonstrating the Individual’s Potential Contribution
Authors: Kugler Gili 
Published: December 2014

In its reference to the people’s sins in the wilderness, Psalm 106 connects the episode of the spies to the future exile. This idea, that the exile came as a result of the sins of the ancestors, is not found in the Pentateuch. We do find it in Ezekiel 20, in the prophet’s attempt to present the fate of Israel as foretold and deterministic. This paper asks why and in what way the psalmist adopts Ezekiel’s idea and terminology. The psalmist cites Ezekiel’s words almost entirely, acknowledging that the situation of the exile was predetermined. However, in its new context, this idea is altered as the psalmist highlights the people’s ability to influence and ease the severity of their situation.Dans sa référence aux péchés du peuple dans le désert, le Psaume 6 relie l’épisode des espions à l’exil futur. Cette idée que l’exil résulte des péchés des ancêtres ne se trouve pas dans le Pentateuque; on la trouve en Ez. 20, tentative du prophète de présenter le destin d’Israël comme annoncé et prédéterminé. Cette étude vise à comprendre pourquoi et de quelle manière le Psalmiste adopte l’idée et la terminologie d’Ezéchiel; il cite les paroles du prophète presqu’entièrement et reconnaît ainsi que la situation de l’exil était prédéterminée. Cette idée est cependant modifiée dans son nouveau contexte, dans la mesure où le Psalmiste relève la capacité du peuple à changer et à alléger la dureté de sa situation.Mit seinem Verweis auf die Sünden des Volkes in der Wüste verbindet Ps 106 die Kundschafterepisode mit dem zukünftigen Exil. Die Vorstellung, dass das Exil eine Folge der Sünden der Vorfahren war, findet sich so nicht im Pentateuch. Dagegen ist sie in Ez 20 belegt, wo der Prophet versucht, Israels Schicksal als vorhergesagt und vorherbestimmt zu präsentieren. In diesem Aufsatz wird gefragt, warum und in welcher Weise der Psalmist die Vorstellung und die Terminologie Ezechiels aufnimmt. Der Psalmist zitiert Ezechiels Worte fast vollständig und erkennt damit an, dass die Situation des Exils vorbestimmt war. Doch in ihrem neuen Kontext wird diese Vorstellung insofern verändert, als der Psalmist die Fähigkeit des Volkes, die Schwere seiner Situation zu beeinflussen und zu erleichtern, hervorhebt.
On the compression softening effect of prestressed beams
Authors: Khang Nguyen Van , Dien Nguyen Phong , Huong Nguyen Thi Van 
Published: December 2014

The main objective of the present paper is to study the transverse vibration of the prestressed beams. The differential equation of the transverse vibration of the Euler-Bernoulli beam is developed, in which the initial axial strain in every cross section of the beam is taken into account, so that the initial normal stress is not equal to zero. We have proposed some formulae to determine the natural frequencies of the prestressed beam. The forced transverse vibration of the beam with a moving external force has been considered. From this it follows compression softening effect of prestressed beams. A detailed comparison between the calculating results for the prestressed and the non-prestressed beam is also presented.

Authors: Tinh Nguyen Duc 
Published: December 2014

For many years the higher order stochastic averaging method has been widely used for investigating nonlinear systems subject to white and coloured noises to predict approximately the response of the systems. In the paper the method is further developed for two-degree-of-freedom systems subjected to white noise excitation. Application to Duffing oscillator is considered.

Authors: Bich Dao Huy , Phu Khuc Van 
Published: December 2014

In the present paper the governing equations for corrugated cross-ply laminated composite plates in the form of a sine wave are developed based on the Kirchoff-Love's theory and the extension of Seydel's technique. By using Bubnov-Galerkin method approximated analytical solutions to the non-linear stability problem of corrugated laminated composite plates subjected to biaxial loads are investigated. The post buckling load-deflection curve of corrugated plates and analytical expressions of the upper and lower buckling loads are presented. The effectiveness of corrugated plates in enhancing the stability compared with corresponding fiat plates is given.
Calculation of loading-induced tendon slip in beams prestressed with external tendons. Part II: Numerical analysis
Authors: Diep Bui Khac , Quang Lam Huu 
Published: December 2014

In this paper, a computing method for the tendon slip based on the force equilibrium condition at deviators was proposed. The proposed method for the evaluation of tendon slip was presented in a general form by taking into account all possibilities of tendon slip at deviators, and several factors found to be important that affect the tendon slip, such as effects of the slippage at two adjacent deviators, friction, change of tendon angles during the applied load, etc. The validation of the proposed method was verified by comparing with the experimental results. The predicted results showed a close agreement with the experimental observation.
Application of the curvature smoothing technique for four-node quadrilateral Reissner-Mindlin plate element
Authors: Hung Nguyen Xuan , Phong Ngo Thanh 
Published: December 2014

A quadrilateral element with smoothed curvatures for Reissner-Mindlin structure plates is proposed. A curvature matrix at an arbitrary point is normalized by a non-local approximation over a smoothing function. By choosing a constant smoothed function and applying the divergence theorem, the bending stiffness matrix calculated on boundaries of smoothing elements (smoothing cells) instead of on their interior. Several numerical results are analyzed to demonstrate high reliability and free locking of the proposed method.
Finite element analysis of laminated composite plates using high order shear deformation theory
Authors: Khoa Ngo Nhu , Thinh Tran Ich 
Published: December 2014

A rectangular non-conforming element based on Reddy's higher-order shear deformation plate theory is developed. Although the plate theory is quite attractive but it could not be exploited as expected in finite-element analysis. This is due to the difficulties associated with satisfaction of inter-elemental continuity requirement and satisfy zero shear stress boundary conditions of the plate theory. In this paper, the proposed element is developed where Reddy's plate theory is successfully implemented. It has four nodes and each node contains 7 degrees of freedom. The performance of the element is tested with different numerical examples, which show its precision and range of applicability.
Using Betts-Miller-Janjic convective parameterization scheme in H14-31 model to forecast heavy rainfall in Vietnam
Authors: Hang Vu Thanh , Xin Kieu Thi 
Published: December 2014

According to Krishnamurti, improvements of physical parameterizations will mainly affect simulations for the tropics [10]. The study of William A. Gallus Jr. showed that the higher the model resolution and more detailed convective parameterizations, the better the skill in quantitative precipitation forecast (QPF) in general [16]. The quality of precipitation forecast is so sensitive to convective parameterization scheme (CPS) used in the model as well as model resolution. The fact shows that for high resolution regional model like H14-31 CPS based on low-level moisture convergence as Tiedtke did not give good heavy rainfall forecast in Vietnam. In this paper we used the scheme of Betts-Miller-Janjic (BMJ) based on the convective adjustment toward tropical observationally structures in reality instead of Tiedtke in Hl4-31. Statistical verification results and verification using CRA method of Hl4-31 of two CPSs for seperated cases and for three rain seasons (2003-2005) shows that heavy rainfall forecast of Hl4-31/BMJ is better than one of H14-31/TK for Vietnam-South China Sea. CRA verification also shows that it is possible to say that heavy rainfall forecast skill of l-I14-31/BMJ in tropics is nearly similar to the skill of LAPS of Australia.
Formulation of the membership function and determination of the input of fuzzy loads in the structural fuzzy analyzing problem
Authors: Pho Nguyen Van 
Published: December 2014

The fuzzy analyzing process consists of different steps. In this paper, the author considers only the method for formulation of the membership function of fuzzy loads acting on the structure. Based on the membership function of fuzzy loads, the combinations of deterministic of the regression analyzing process will be determined. The membership function of fuzzy loads is selected by the triangular membership function. It is in conformity with the concept on selection of loads in the design standards. The combination of inputs for the analyzing process will be determined, based on the number of present times of the value of input parameters (including the deterministic parameters, fuzzy parameters and the random ones) in the schema of analysis. The number of present times of input parameters is either proportional to value of the corresponding membership function or to the value of the probabilistic density function. A method for determining the appropriate combination of deterministic inputs so that each input parameter will present only one time in each combination is proposed. To illustrate the proposed method, an example on the determination of input combinations of tornado's velocity in Vietnam is presented.
Influences of the compressibility on aerodynamic characteristics of profile under the transonic flow theory
Authors: Ngoc Hoang Thi Bich 
Published: December 2014

Transonic flows are complex problems. At certain Mach numbers, in gas flows there are local transitions from the subsonic into the supersonic and reciprocally, especially the discontinuity throughout shock waves. Subsonic flows and supersonic flows have very different properties, thus calculation methods are also different-the subsonic equation is elliptic and the supersonic equation is hyperbolic. Using established programs (based on the incompressible theory, the compressible theory and the transonic theory), we studied sub-transonic flow characteristics with variations of the Mach number. Our studies are also carried out with variations of incidence, which impact on t he transonic effect. Numerical results show that the local compressibility depends on not only the speed but also the incidence. At a rather great angle of attack, local supersonic regions can appear with free Mach numbers in the order of 0.3 - the Mach number is normally considered as a speed of incompressible flows. According to these results, we can recognize for which regime the local compressibility of flow is considerable and then it is necessary to consider the problem under the transonic flow theory.
A new finite element for free vibration analysis of stiffened composite plates
Authors: Thinh Tran Ich , Khoa Ngo Nhu 
Published: December 2014

A new 6-noded stiffened triangular plate element for the analysis of stiffened composite plates based on Mindlins deformation plate theory has been developed. The stiffened plate element is a combination of basic triangular element and bar component. The element can accommodate any number of arbitrarily oriented stiffeners and obviates the use of mesh lines along the stiffeners. Free vibration analyses of stiffened laminated plates have been carried out with this element and the results are compared with those published. The finite element results show very good matching with the experimental ones.
A unified Krylov-Bogoliubov-Mitropolskii method for solving hyperbolic-type nonlinear partial differential systems
Authors: Islam M. Zahurul , Alam M. Shamsul , Hossain M. Bellal 
Published: December 2014

A general asymptotic solution is presented for investigating the transient response of non-linear systems modeled by hyperbolic-type partial differential equations with small nonlinearities. The method covers all the cases when eigen-values of the corresponding unperturbed systems are real, complex conjugate, or purely imaginary. It is shown that by suitable substitution for the eigen-values in the general result that the solution corresponding to each of the three cases can be obtained. The method is an extension of the unified Krylov-Bogoliubov-Mitropolskii method, which was initially developed for un-darnped, under-clamped and over-clamped cases of the second order ordinary differential equation. The methods also cover a special condition of the over-damped case in which the general solution is useless.
An extension of the identification algorithm for feedback active control of incomplete measured systems
Authors: Viet La Duc , Anh Nguyen Dong 
Published: December 2014

In a previous paper [1], the identification algorithm is presented for feedback active controlled systems. However, this method can only be applied to complete measured systems. The aim of this paper is to present a combination of the identification algorithm and the modal superposition method to control the incomplete measured systems. The system response is expanded by modal eigenfunction technique. The external excitation acting on some first modes is identified with a time delay and with a small error depending on the sensor locations. Then the control forces will be generated to balance the identified excitations. A numerical simulation is applied to an eight story building subjected to base acceleration.
Numerical simulation of the crack 2D by the finite element incorporated the discontinuity
Authors: Giang Nguyen Truong 
Published: December 2014

Determining stress intensity factors is important in fracture mechanics. The extended finite element method (XFEM) provides a robust and accurate to determine factors. This paper describes some results from the analysis of cracked plates using XFEM. Extended finite elements allow the entire crack to be represented independently of the meshing. The elements employ discontinuous functions and the facture mechanics two dimensional asymptotic crack tip displacement fields. The Fortran source code of Cast3M applies these elements to a set of examples. The obtained stress and deformation fields are used to compute stress intensity factors via interaction integrals. The results are compared with these obtained from conventional FEM to demonstrate the advantages of the employing the new elements.
A new approach for investigating corrugated laminated composite plates of wave form
Authors: Bich Dao Huy , Phu Khuc Van 
Published: December 2014

Corrugated plates of wave form made of isotropic elastic material were considered as flat orthotropic plates with corresponding orthotropic constants determined empirically by the Seydel’s technique. In some recent researches the extension of this technique was given for corrugated laminated composite plates. In the present paper a new approach for investigating corrugated composite plate of wave form is proposed, regarding this plates as a combination of parts of shallow cylindrical shells with alternative curvatures. It reduces to no use of Seydel’s empirical formulas and sufficiently apply to composite plates. Based on this approach governing equations of corrugated laminated composite plate of wave form are developed and application to the non-linear stability problem of this plate is considered. Obtained results are compared with those of Seydel’s technique.

Authors: Can Ngo Huy , Don Nguyen Thanh , Phong Nguyen Hong , Anh Nguyen Tuan , Que Nguyen Van 
Published: December 2014

In the paper the optimal operation of Hoabinh reservoir for flood control on Hong–Thai Binh river system is presented. The findings show that in the flood season in 1996 if the operation of gates and outlets of Hoa Binh reservoir was made base on the calculated release, the water level at Hanoi would be 12.3 m and the water level of Hoa Binh reservoir would be 98 m. So the calculated release from Hoabinh reservoir in August 1996 can be considered as optimal in the mean that the water level at Hanoi can be controlled and the Hoabinh reservoir still have necessary pool for controlling the next floods.

Authors: Cuong Nguyen Tien , Phuong Trinh Thu 
Published: December 2014

Da river is the biggest one of three rivers: Da, Thao and Lo which flow into Hong river, so calculating and forecasting correctly the discharge to Hoa Binh reservoir take an important role in managing the task of flood preventing in the Hong - Thai Binh river system. In this paper, a connected hydraulic-hydrological model is developed. The model was applied to forecast the discharge into Hoa Binh reservoir in the flood season 2006. The difference of this connected hydraulic-hydrological model in comparison with the other hydrological models is using the complete Saint-Venant 1D to simulate flow in rivers. Results of verification of the model show that it is good enough for practice.

Based on the linearized equations of motion, a controller is designed to maintain a stable motion of the robot. Some numerical simulation results are shown to clarify the designed controller.
A molecular dynamics/extended finite element method for dynamic crack propagation
Authors: Aubertin Pascal , Réthoré Julien , Borst René de 
Published: December 2014

A multiscale method is presented which couples a molecular dynamics approach for describing fracture at the crack tip with an extended finite element method for discretizing the remainder of the domain. After recalling the basic equations of molecular dynamics and continuum mechanics the discretization is discussed for the continuum subdomain where the partition-of-unity property of finite element shape functions is used, since in this fashion the crack in the wake of its tip is naturally modelled as a traction-free discontinuity. Next, the zonal coupling method between the atomistic and continuum models is described, including an assessment of the energy transfer between both domains for a one-dimensional problem. Finally, a two-dimensional computation is presented of dynamic fracture using the coupled model.
On FSUM model and applications
Authors: Chung Dang Huu 
Published: December 2014

In this paper a 3D model (FSUM) on tidal flows with sediment transport and bed morphology process taking into account the temperature-salinity exchange in estuaries and coastal zones is introduced in more detail. The implicit finite difference method based on semi-Lagrange splitting is used. The software is coded with FORTRAN 90/95. The open boundary condition kinds together source/sink terms are well treated so that it can be applied to every computing domain with the complicated geometry. The software is validated and applied for many different cases and shows the ability of application in practice.
