Authors: Alfino Pramuji Akbar  , Nurul Fitriani  , Bambang Istiyanto  
Published: December 2024

ABSTRAK
Peningkatan jumlah penduduk turut menyebabkan adanya permasalahan transportasi, seperti kemacetan dan polusi udara. Salah satu upaya yang dapat dilakukan adalah penggunaan angkutan umum. Akan tetapi, minat masyarakat untuk menggunakan angkutan umum masih tergolong rendah, tidak terkecuali dengan masyarakat di Kota Semarang. Padahal, saat ini Pemerintah Kota Semarang telah menyediakan transportasi umum modern yaitu Trans Semarang. Oleh karena itu peneliti bermaksud untuk menganalisis variabel-variabel yang menjelaskan penggunaan Trans Semarang dengan metode Structural Equation Modelling (SEM). Metode SEM memungkinkan mengetahui signifikansi pengaruh antar variabel lebih dari satu variabel bebas maupun terikat. Penelitian menggunakan kepuasan penumpang dan kualitas pelayanan sebagai variabel bebas. Adapun persepsi dan perilaku penumpang menjadi variabel terikat. Hasil penelitian yang dilakukan, menunjukkan bahwa empat variabel penelitian dianggap berpengaruh terhadap penggunaan Trans Semarang.
ABSTRACT
The increase in population causes transportation problems, such as traffic jams and air pollution. One effort that can be done is use public transport. However, people’s interest to using public transport is still relatively low, no exception people in Semarang. In fact, currently The Goverment of Semarang has provided modern public transport, that is Trans Semarang. Therefore, the researcher intends to analyze variables that influence of Trans Semarang usage using Structural Equation Modelling (SEM) method. SEM method makes it posible to determine the significance of influence between variables of more than one independent or dependent variable. Research uses passenger satisfaction and service quality as independent variables. Perceptions and passanger behavior are dependent variables. The result of this research showed that four variables are considered to influence using Trans Semarang.

Authors: Abdulelah Furqan , M. Mohammed Mohammed , Hassan Baaker Rabab 
Published: December 2024

Mucopolysaccharidosis (MPS) is a rare heterogenous progressive genetic disorder, which is a subset of lysosomal storage diseases with a consequence of glycosaminoglycans building-up inside the lysosomes which attributed to enzymes absence or deficiency. This study was aimed to identify mutations that associated with mucopolysaccharidosis of Iraqi children in different Iraqi metabolic centers. While in concerning to the genetic study, the eligible patients who had no genetic analysis and who are not received hematopoietic stem cells transportation were enrolled in this study for molecular confirmation of mucopolysaccharidosis disorders and reporting the existence of any new variants among Iraqi patients. Consequently, the study reports various SNPs are responsible for different MPS types, for instance, there are seven SNPs within IDAU gene of MPS I Iraqi patients, the most frequent one was rs794726877 which accounts for missense c.152G>A. Finally, the study recommends establishment of awareness programs for affected families regarding the genetic conditions, inheritance pattern and potential availability of reproductive options such as In Vitro Fertilization (IVF), educate the population at risk about the risk of genetic disease transmission as a result of inbreed marriage and necessity of availability of prenatal screening and pregnancy termination option in Iraq.
Dispersive effects for nonlinear geometrical optics with rectification
Authors: Lannes David 
Published: December 2024

Oscillating approximate solutions to nonlinear hyperbolic dispersive systems are studied. Ansatz of three scales are used in order to deal with diffractive effects. The scaling of the approximate solutions is chosen so that diffractive, dispersive effects and rectification are present in the leading term. The propagation along the rays of geometrical optics of the oscillating Fourier coefficients of the leading terms is corrected by a Schrödinger dispersion which appears for long times only. The propagation of the nonoscillating Fourier coefficient depends on the properties of a symmetric hyperbolic system, whose characteristic variety is the tangent cone at $0$ to the characteristic variety of the initial operator. Equations determining the leading term require a sublinear growth condition for the corrector and the inroduction of the analytical “average operators” which convey this sublinear growth condition in a simple way and sort the nonlinearities out. In the last part, detailed physical examples are given.
A result on the decay of the boundary layers in the homogenization theory
Authors: Neuss‐Radu Maria 
Published: December 2024

Boundary layers are used in the homogenization of elliptic problems with periodically oscillating coefficients, for example when we want to improve the macroscopic approximation given by homogenization in the neighborhood of the boundary of a domain. For problems with a special geometry the boundary layers are defined on a semi‐infinite strip $]0,1[^{n-1}\times]0,\infty[\,$ , and their energies decrease exponentially with respect to the second variable. In our paper, we show that in general this decay property does not hold, i.e., we cannot get uniform exponential decay of the boundary layers.
Approximation de Born–Oppenheimer de sections efficaces totales diatomiques
Authors: Jecko Th. 
Published: December 2024

[fr] Pour des molécules diatomiques dans la limite de Born–Oppenheimer, on construit une approximation adiabatique de plusieurs sections efficaces totales, y compris des sections inélastiques. On montre la prépondérance de la diffusion élastique et l’on en donne des termes dominants. L’un d’eux contient un potentiel effectif, ce qui permet de réduire la diffusion à celle d’un système à deux corps. De plus, l’approximation améliore une borne a priori sur d’autres sections totales. Abstract. In the Born–Oppenheimer limit, for diatomic molecules, we approximate several total cross‐sections, including inelastic ones, by adiabatic equivalents. We show the preponderance of the elastic total cross‐section and we give leading terms for it. One of them contains a two‐body efficient potential so that the scattering behaviour may be well‐approximated by those of some two‐body system. Furthermore, the adiabatic approximation improves an a priori bound on some other total cross‐sections.
Optimal conditions of convergence and effects of anisotropy in the homogenization of non‐uniformly elliptic problems
Authors: Briane Marc 
Published: December 2024

This paper is devoted to the homogenization of the problem −div(aε∇uε)+ν uε=f in a bounded domain Ω of Rd, with Neumann's (ν=1) or Dirichlet's (ν=0) boundary conditions. The conductivity matrix aε is defined by $a_{\varepsilon }(x):=A_{\varepsilon }(\tfrac{x}{\varepsilon })$ where (Aε)ε>0 is a sequence of bounded but non‐uniformly elliptic periodic matrix‐valued functions. We make a general assumption on Aε for that the sequence uε strongly converges in L2(Ω) to a function u0 solution of a similar problem. We also yield an example in which the compactness result holds true although the sequence Aε uniformly looses its ellipticity as ε tends to zero. Finally we illustrate the optimality of our condition on Aε in the framework of isolating thin layers.
Asymptotic developments of analytic functions in cones
Authors: Meana Jorge Jiménez 
Published: December 2024

In this paper we give a definition of asymptotic development of an analytic function of several complex variables. So far, there existed two different definitions which are joined by the definition given in this paper. This definition generalizes, in a natural sense, the one given for one variable. The generalization is made by changing the object polysector by a conoidal domain which is more general because all the polysectors are conoidal domains but not all the conoidal domains are polysectors. It is given a characterization of the analytic functions that admit asymptotic developments in a cone as those which restricted to a closed subcone admit an extension of class 𝒞∞. It is proven that, through this definition, the asymptotic developments of analytic functions of several variables verify all the good properties of the asymptotic developments of analytic functions of one variable.
A complex WKB method for adiabatic problems
Authors: Fedotov Alexander , Klopp Frédéric 
Published: December 2024

This work is devoted to a new version of the complex WKB method suited for adiabatic perturbations of one‐dimensional periodic Schrödinger operators. Therefore, we introduce an additional parameter, and it is this parameter (and not the variable of the equation) that will become complex. This naturally leads to canonical domains where we construct solutions of the Schrödinger equation with a standard asymptotic behavior. These can be used to compute the asymptotics of the exponentially small coefficients of transfer matrices (e.g., scattering matrices, monodromy matrices, etc.). We give an example of such a computation. Résumé. Ce travail est consacré à une nouvelle version de la méthode BKW complexe adaptée à l'étude des perturbations adiabatiques d'équations de Schrödinger périodiques en dimension 1. Nous introduisons un paramètre supplémentaire; c'est ce paramètre qui sera rendu complexe (au lieu de la variable de l'équation). Ceci nous conduit de façon naturelle à la définition des domaines canoniques dans lesquels on construit des solutions aux comportements asymptotiques connus. Ces développements asymptotiques peuvent être utilisés pour contrôler l'asymptotique des coefficients exponentiellement petits de matrices de transfert (par exemple, de matrices de diffusion, de matrices de monodromie, etc.). On donne un exemple d'un tel calcul.
Asymptotic derivation of a Navier condition for the primitive equations
Authors: Bresch D. , Guillén‐González F. , Masmoudi N. , Rodríguez‐Bellido M.A. 
Published: December 2024

This paper is devoted to the establishment of a friction boundary condition associated with the hydrostatic Navier–Stokes equations (also called the primitive equations). Usually the Navier boundary condition is used, as a wall law, for a fluid governed by the Navier–Stokes equations when we want to modelize roughness. We consider here an anisotropic Navier boundary condition corresponding to the anisotropic Navier–Stokes equations. By an asymptotic analysis with respect to the aspect ratio of the domain, we obtain a friction boundary condition for the limit system, that is the primitive equations. This asymptotic boundary condition only concerns the trace of the horizontal components of the velocity field and the trace of its vertical derivative.
Global existence and asymptotic behaviour for a mildly degenerate dissipative hyperbolic equation of Kirchhoff type
Authors: Ghisi Marina , Gobbino Massimo 
Published: December 2024

We investigate the evolution problem u"+δu'+m(|A1/2u|2)Au=0, u(0)=u0,  u'(0)=u1, where H is a Hilbert space, A is a self‐adjoint non‐negative operator on H with domain D(A), δ>0 is a parameter, and m :[0,+∞[→[0,+∞[ is a locally Lipschitz continuous function. We prove that this problem has a unique global solution for positive times, provided that the initial data (u0,u1)∈D(A)×D(A1/2) satisfy a suitable smallness assumption and the non‐degeneracy condition m(|A1/2u0|2)>0. Moreover (u(t),u′(t),u″(t))→(u∞,0,0) in D(A)×D(A1/2)×H as t→+∞, where |A1/2u∞|m(|A1/2u∞|2)=0. These results apply to degenerate hyperbolic PDEs with non‐local non‐linearities.
Non‐local interactions in the homogenization closure of thermoelectric functionals
Authors: Camar‐Eddine M. , Milton G.W. 
Published: December 2024

It is a very well‐known fact that the effective properties of a heterogeneous electrical medium may contain a non‐local term. The same phenomenon can occur within a heterogeneous thermally conducting medium. We are interested in the set of all non‐local interactions which may arise from the homogenization of a thermoelectric medium where there are couplings between the temperature and the electric field. We consider a bounded open subset Ω⊂ $\mathbb{R}^{3}$ and we show that any non‐local energy of the kind F(u,v)=∫Ω×Ω $\pmatrix{u(x)-u(y)\cr v(x)-v(y)\cr}$ ·μ(dx,dy) $\pmatrix{u(x)-u(y)\cr v(x)-v(y)\cr}$ , belongs to the closure of the set of thermoelectric functionals, provided that the positive definite symmetric matrix‐valued measure μ(dx,dy) makes this energy functional continuous in the strong topology of L2(Ω, $\mathbb{R}^{2}$ ).
On a nonlinear coupled system for the beam equations with memory in noncylindrical domains
Authors: Santos M.L. , Rocha M.P.C. , Ferreira J. 
Published: December 2024

We prove the exponential decay in the case n>2 as time goes to infinity of regular solutions for the nonlinear coupled system of beam equations with memory and weak damping utt+Δ2u−Δu+∫t0g1(t−s)Δu(s) ds+αut+h(u−v)=0  in $\[$\widehat{Q}$$ , vtt+Δ2v−Δv+∫t0g2(t−s)Δv(s) ds+αvt−h(u−v)=0  in $\[$\widehat{Q}$$ in a noncylindrical domains of $\[$\mathbb{R}^{n+1}$$ (n≥1) under suitable hypothesis on the scalar functions g1, g2 and h where α is a positive constant. Observe that the coupled is nonlinear and we worked directly in the noncylindrical domain that presents some technical difficulties turning the interesting problem. We establish existence and uniqueness of regular solutions for any n≥1.
Asymptotic expansion of the solution of an interface problem in a polygonal domain with thin layer
Authors: Caloz Gabriel , Costabel Martin , Dauge Monique , Vial Grégory 
Published: December 2024

We consider the solution of an interface problem posed in a bounded domain coated with a layer of thickness ε and with external boundary conditions of Dirichlet or Neumann type. Our aim is to build a multi-scale expansion as ε goes to 0 for that solution. After presenting a complete multi-scale expansion in a smooth coated domain, we focus on the case of a corner domain. Singularities appear, obstructing the construction of the expansion terms in the same way as in the smooth case. In order to take these singularities into account, we construct profiles in an infinite coated sectorial domain. Combining expansions in the smooth case with splittings in regular and singular parts involving the profiles, we construct two families of multi-scale expansions for the solution in the coated domain with corner. We prove optimal estimates for the remainders of the multi-scale expansions.

Authors: Mercaldo Anna , Mossino Jacqueline , Prignet Alain 
Published: December 2024

We study the asymptotic behaviour, as ε goes to zero, of the entropy solution uε to a class of nonlinear elliptic problems whose prototype is −div((δε)p−1|∇uε|p−2∇uε)=fε in Ωε, uε=0 on ∂Ωε, where 1<p<N, $\varOmega^{\varepsilon}=\overline{\varOmega}\cup\Sigma^{\varepsilon}$ , Ω⊂RN is a bounded domain of class C1,1, surrounded along its boundary by a layer Σε of small thickness ε, δε=1 in Ω, δε=ε in Σε, and fε belongs to L1(Ωε). The solutions uε also satisfies natural transmission conditions on ∂Ω.
Revealed Preference, Congruence and Rationality: A Fuzzy	Approach
Authors: Georgescu Irina 
Published: December 2024

In a previous paper connections between the congruence axioms WFCA, SFCA and the revealed preference axioms WAFRP, SAFRP for fuzzy choice functions whose domain contains the characteristic functions of pairs and of triples of alternatives have been studied. The first objective of this paper is to establish such connections for the case of arbitrary fuzzy choice functions. We introduce the new revealed preference axioms WAFRP ^o , SAFRP ^o , HAFRP and we prove two main theorems: 1. The axioms WFCA and WAFRP ^o are equivalent; 2. The axioms SFCA and HAFRP are equivalent. Our second objective is to define G-rational, M-rational, G-normal and M-normal fuzzy choice functions and to investigate some of their properties. The notions and the results are formulated in terms of the residuum of the Gödel t-norm and the proofs use the residuated lattice structure of the interval [0,1].
Generalized Interpolation in First Order Logic
Authors: Borzyszkowski Tomasz 
Published: December 2024

We consider the Craig Interpolation Property for many sorted first-order logic. The Craig Interpolation Property explored in this paper is inspired by the institution independent generalization of this property presented in [21]. In [3] the author presents the interpolation result for the institution of many sorted first-order logic, with both morphisms in the pushout square being injective on sort names. The author also shows that the Craig Interpolation Property does not hold when both morphisms are certain morphisms which are noninjective on sort names. An open question in that paper was whether the interpolation property holds with only one morphism being injective on sort names. In this paper we give answer to this question. Following the overall structure of the classical proof presented in [7] for single sorted first-order logic, but with new technicalities concerning the many sorted case, we show that many sorted first-order logic has the interpolation property when just one (left or right) morphism is injective on sort names.
A Formal Language Analysis of DNA Hairpin Structures
Authors: Kari L. , Losseva E. , Konstantinidis S. , Sosík P. , Thierrin G. 
Published: December 2024

The concept of hairpin structures in formal languages is motivated from the biocomputing and bioinformatics fields. Hairpin (-free) DNA structures have numerous applications to DNA computing and molecular genetics in general. A word is called hairpin-free if it cannot be written in the form xuyθ(u)z, with certain additional conditions, for an involution θ (a function θ with the property that θ ^2 equals the identity function). A particular involution, the so-called Watson-Crick involution, can characterize binding of two DNA strands. We study algebraic and decision properties, finiteness and descriptional complexity of hairpin (-free) languages. We show an existence of polynomial-time algorithms deciding hairpin-freeness of regular and context-free sets. Two related DNA secondary structures are considered, taking into the account imperfect bonds (bulges, mismatches) and multiple hairpins. Finally, effective methods for design of long hairpin-free DNA words are given.
Limits of Modularity
Authors: Bednarczyk Marek A. 
Published: December 2024

It has been observed that various synchronisation operators underlying the modular design of concurrent systems can be explained as pullbacks in suitable categories of concurrent systems. Here, the boundaries of such approach are investigated. For this purpose we study the issue of completeness in categories of trace monoids. It turns out that (finite) completeness is achieved if trace monoids with concurrency preserving homomorphisms are considered. Taking arbitrary monoid homomorphisms leads, in general, to incompleteness. The results obtained are used to reveal an area in which the code problem for trace monoids, undecidable in general, has always a positive answer.
An Algorithmic Solution of a Birkhoff Type Problem
Authors: Simson Daniel , Wojewódzki Mariusz 
Published: December 2024

We give an algorithmic solution in a simple combinatorial data of Birkhoff0s type problem studied in [22] and [25], for the category rep _{ft} (I,K[t]/(t ^m )) of filtered I-chains of modules over the K-algebra K[t]/(t ^m ) of K-dimension m <∞, where m ⩾ 2, I is a finite poset with a unique maximal element, and K is an algebraically closed field. The problem is to decide when the indecomposable objects of the category rep _{ft} (I,K[t]/(t ^m )) admit a classification by means of a suitable parametrisation. A complete solution of this important problem of the modern representation theory is contained in Theorems 2.4 and 2.5. We show that rep _{ft} (I,K[t]/(t ^m )) admits such a classification if and only if (I,m) is one of the pairs of the finite list presented in Theorem 2.4, and such a classification does not exist for rep _{ft} (I,K[t]/(t ^m )) if and only if the pair (I,m) is bigger than or equal to one of the minimal pairs of the finite list presented in Theorem 2.5. The finite lists are constructed by producing computer accessible algorithms and computational programs written in MAPLE and involving essentially the package CREP (see Section 4). On this way the lists are obtained as an effect of computer computations. In particular, the solution we get shows an importance of the computer algebra technique and computer computations in solving difficult and important problems of modern algebra.
