The Relationships Among Leadership Styles, Entrepreneurial Orientation, and Business Performance
This study aims to contribute to the knowledge of leadership styles and entrepreneurial orientation at small and medium enterprises as well as their effects on business performance. This study examines how leadership style can affect the development and implementation of entrepreneurial orientation in small and medium enterprises in Taiwan. It is also designed to examine the effects of leadership styles and entrepreneurial orientation on business performance. Significant conclusions from this study are that different leadership styles may affect business performance; that transformational leadership is significantly more correlated to the business performance than is transactional leadership and passive-avoidant leadership; that entrepreneurial orientation is positively related to performance; and that transformational leadership with higher entrepreneurial orientation can contribute to higher business performance.leadership styles, entrepreneurial orientation, business performance
Fabrication of Miniaturized Variable-focus Lens Using Liquid Filling Technique
This paper describes a simple method for fabricating a variable-focus lens by
using PDMS (polydimethylsiloxane) and filling with liquid for the
variable-focus lens. The lens diameter of 2-mm was designed in this experiment
and expected to reach the focal length in the range of 3 ~ 12 mm. The
theoretical value between the liquid volume and the lens contact angle at
different focal lengths were simulated and measured. The pumped-in volumes
ranged from 200 to 1400 l, the contact angles ranged from 14.25 degrees to
49.02 degrees. Changing the deformation of PDMS film using different
micro-fluidic volume produces the variable focal length from 4 10 mm in this
experiment. The proposed method successfully fabricated a variable-focus lens.
Bonding PDMS only once using no expensive instrument such as oxygen plasma was
accomplished. The final objective is to insert the variable focus lens into
portable optical imagery products.Comment: Submitted on behalf of EDA Publishing Association

Self-imitating Feedback Generation Using GAN for Computer-Assisted Pronunciation Training
Self-imitating feedback is an effective and learner-friendly method for
non-native learners in Computer-Assisted Pronunciation Training. Acoustic
characteristics in native utterances are extracted and transplanted onto
learner's own speech input, and given back to the learner as a corrective
feedback. Previous works focused on speech conversion using prosodic
transplantation techniques based on PSOLA algorithm. Motivated by the visual
differences found in spectrograms of native and non-native speeches, we
investigated applying GAN to generate self-imitating feedback by utilizing
generator's ability through adversarial training. Because this mapping is
highly under-constrained, we also adopt cycle consistency loss to encourage the
output to preserve the global structure, which is shared by native and
non-native utterances. Trained on 97,200 spectrogram images of short utterances
produced by native and non-native speakers of Korean, the generator is able to
successfully transform the non-native spectrogram input to a spectrogram with
properties of self-imitating feedback. Furthermore, the transformed spectrogram
shows segmental corrections that cannot be obtained by prosodic
transplantation. Perceptual test comparing the self-imitating and correcting
abilities of our method with the baseline PSOLA method shows that the
generative approach with cycle consistency loss is promising

Rankine-Hugoniot Relations in Relativistic Combustion Waves
As a foundational element describing relativistic reacting waves of relevance
to astrophysical phenomena, the Rankine-Hugoniot relations classifying the
various propagation modes of detonation and deflagration are analyzed in the
relativistic regime, with the results properly degenerating to the
non-relativistic and highlyrelativistic limits. The existence of
negative-pressure downstream flows is noted for relativistic shocks, which
could be of interest in the understanding of the nature of dark energy. Entropy
analysis for relativistic shock waves are also performed for relativistic
fluids with different equations of state (EoS), denoting the existence of
rarefaction shocks in fluids with adiabatic index \Gamma < 1 in their EoS. The
analysis further shows that weak detonations and strong deflagrations, which
are rare phenomena in terrestrial environments, are expected to exist more
commonly in astrophysical systems because of the various endothermic reactions
present therein. Additional topics of relevance to astrophysical phenomena are
also discussed.Comment: 34 pages, 9 figures, accepted for publication in Ap
