SME Innovation in the Malaysian Manufacturing Sector

This paper examines the determinants of innovation amongst small and medium enterprises in the Malaysian manufacturing sector using firm-level data. For small-sized firms, younger firms are more likely to innovate compared to older firms. However, for medium-sized and large-sized firms, older firms are more likely to innovate. The extent of foreign ownership is not an important determinant of innovation. Small-sized firms with more employees are more likely to innovate. Medium-sized firms that produce for domestic market tend to be more innovative. In terms of ownership structure, medium-sized firms that are public limited companies are less likely to innovate. The relationship between technological characteristics of industry and firms' likelihood to innovate appear to be complex. Higher market concentration is associated with higher probability to innovate for medium-sized firms.

Applying the structural equation model rule-based fuzzy system with genetic algorithm for trading in currency market

The present study uses the structural equation model (SEM) to analyze the correlations between various economic indices pertaining to latent variables, such as the New Taiwan Dollar (NTD) value, the United States Dollar (USD) value, and USD index. In addition, a risk factor of volatility of currency returns is considered to develop a risk-controllable fuzzy inference system. The rational and linguistic knowledge-based fuzzy rules are established based on the SEM model and then optimized using the genetic algorithm. The empirical results reveal that the fuzzy logic trading system using the SEM indeed outperforms the buy-and-hold strategy. Moreover, when considering the risk factor of currency volatility, the performance appears significantly better. Remarkably, the trading strategy is apparently affected when the USD value or the volatility of currency returns shifts into either a higher or lower state.Knowledge-based Systems, Fuzzy Sets, Structural Equation Model (SEM), Genetic Algorithm (GA), Currency Volatility

Nuts and bolts of supersymmetry

A topological mechanism is a zero elastic-energy deformation of a mechanical structure that is robust against smooth changes in system parameters. Here, we map the nonlinear elasticity of a paradigmatic class of topological mechanisms onto linear fermionic models using a supersymmetric field theory introduced by Witten and Olive. Heuristically, this approach consists of taking the square root of a non-linear Hamiltonian and generalizes the standard procedure of obtaining two copies of Dirac equation from the square root of the linear Klein Gordon equation. Our real space formalism goes beyond topological band theory by incorporating non-linearities and spatial inhomogeneities, such as domain walls, where topological states are typically localized. By viewing the two components of the real fermionic field as site and bond displacements respectively, we determine the relation between the supersymmetry transformations and the Bogomolny-Prasad-Sommerfield (BPS) bound saturated by the mechanism. We show that the mechanical constraint, which enforces a BPS saturated kink into the system, simultaneously precludes an anti-kink. This mechanism breaks the usual kink-antikink symmetry and can be viewed as a manifestation of the underlying supersymmetry being half-broken.Comment: 14 pages, 5 figure

Apogee motor rocketry reliability improvements

Since 1963, solid propellant apogee motors have been placing satellites into geosynchronous orbits. Major technological breakthroughs are not required to satisfy future mission requirements; however, there is a need to improve reliability to enhance cost effectiveness. Several management test options are discussed. A summary of results and conclusions derived from review of missions, where failure of a solid motor was inferred, and correlation of system factors with failures are reported. Highlights of a solid motor diagnostic instrumentation study are presented. Finally, recommendations are provided for areas of future apogee motor upgrade, which will increase project cost effectiveness by reducing the potential for future flight failures

Les bifurcations culturelles du road movie contemporain

L’article examine sous l’angle de l’interculturalité le renouvellement cinématographique du road movie au tournant du xxie siècle. La cohérence que le terme et l’idée de culture confèrent à une reconfiguration de ce genre filmique réside dans les tensions dont se saisissent des films contemporains faisant appel à l’imaginaire de la route pour mettre en rapport enjeux identitaires et appartenance culturelle. L’interculturalité ne se résume donc pas à une simple unité thématique qui reprendrait en écho le discours aujourd’hui dominant du contact et de la diversité culturels. S’appuyant sur une filmographie pour l’essentiel sud-américaine, nord-américaine et européenne, l’étude privilégie trois axes de réflexion, qui isolent chacun une acception distincte du concept de culture et, partant, délimitent une dimension particulière de l’interculturel. Disponibilisation contrariée, asymétrie et opacité relaient ainsi une analyse situant la dimension interculturelle du road movie contemporain au-delà d’une simple interculturalité de figuration.This article examines the resurgence of the road movie at the turn of the twenty-first century from an intercultural perspective. The coherence that the term culture and the idea of culture confer upon the reconfiguration of this film genre resides in the tensions that these contemporary films employ in their appeal to our collective imagination of the road, bringing into play questions of identity and cultural belonging. Interculturality can thus not be reduced to a mere thematic unity reflecting today’s dominant discourse of cultural contact and diversity. In its discussion of an essentially South American, North American and European body of work, this article sets out three avenues of approach, each one isolating a distinct acceptation of the concept of culture and delineating a specific aspect of the intercultural. By focusing on the ambiguity of cultural disembedding, on asymmetrical dynamics and on the issue of opacity, the analysis locates the intercultural dimension of contemporary road movies beyond the mimetics of representation

Kink-antikink asymmetry and impurity interactions in topological mechanical chains

We study the dynamical response of a diatomic periodic chain of rotors coupled by springs, whose unit cell breaks spatial inversion symmetry. In the continuum description, we derive a nonlinear field theory which admits topological kinks and antikinks as nonlinear excitations but where a topological boundary term breaks the symmetry between the two and energetically favors the kink configuration. Using a cobweb plot, we develop a fixed-point analysis for the kink motion and demonstrate that kinks propagate without the Peierls-Nabarro potential energy barrier typically associated with lattice models. Using continuum elasticity theory, we trace the absence of the Peierls-Nabarro barrier for the kink motion to the topological boundary term which ensures that only the kink configuration, and not the antikink, costs zero potential energy. Further, we study the eigenmodes around the kink and antikink configurations using a tangent stiffness matrix approach appropriate for pre-stressed structures to explicitly show how the usual energy degeneracy between the two no longer holds. We show how the kink-antikink asymmetry also manifests in the way these nonlinear excitations interact with impurities introduced in the chain as disorder in the spring stiffness. Finally, we discuss the effect of impurities in the (bond) spring length and build prototypes based on simple linkages that verify our predictions.Comment: 20 pages, 21 figure
