The effectiveness of location incentive: An analytical study of manufacturing SMEs in the Kedah State

The main objective of this research is to find out the effectiveness of location incentive in att racting Small and Medium Enterprises (SMEs) to a certain industrial location in the state of Kedah. The location choice identified in this research would be Sungai Petani and non-Sungai Petani industrial areas. By using the logit model, we found that location incentive is not as effective as other factors in attracting SMEs in setting up their establishments in Kedah. The important factors that influence the location choice of manufacturing SMEs are (i) the years of operation of an SME, and (ii) the physical distribution of an SME product

Role of Electon Excitation and Nature of Molecular Gas in Cluster Central Elliptical Galaxies

We present observations in CO(3-2) that, combined with previous observations in CO(2-1), constrain the physical properties of the filamentary molecular gas in the central $\sim$6.5 kpc of NGC 1275, the central giant elliptical galaxy of the Perseus cluster. We find this molecular gas to have a temperature $\gtrsim 20$ K and a density $\sim$$10^2$-$10^4 {\rm \ cm^{-3}}$, typically warmer and denser than the bulk of Giant Molecular Clouds (GMCs) in the Galaxy. Bathed in the harsh radiation and particle field of the surrounding intracluster X-ray gas, the molecular gas likely has a much higher ionization fraction than that of GMCs. For an ionization fraction of $\sim$$10^{-4}$, similar to that of Galactic diffuse ($\lesssim 250 {\rm \ cm^{-3}}$) partially-molecular clouds that emit in HCN(1-0) and HCO$^+$(1-0), we show that the same gas traced in CO can produce the previously reported emissions in HCN(3-2), HCO$^+$(3-2), and CN(2-1) from NGC 1275; the dominant source of excitation for all the latter molecules is collisions with electrons. To prevent collapse, as evidenced by the lack of star formation in the molecular filaments, they must consist of thin strands that have cross-sectional radii $\lesssim$0.2-2 pc if supported solely by thermal gas pressure; larger radii are permissible if turbulence or poloidal magnetic fields provide additional pressure support. We point out that the conditions required to relate CO luminosities to molecular gas masses in our Galaxy are unlikely to apply in cluster central elliptical galaxies. Rather than being virialized structures analogous to GMCs, we propose that the molecular gas in NGC 1275 comprises pressure-confined structures created by turbulent flows.Comment: 41 pages, 1 table, 12 figures; accepted by Ap

What makes a graduate an agro-entrepreneur?

Realizing the importance of entrepreneurship to economic development, the Malaysian Ministry of Higher Education has launched the Higher Education Institute Entrepreneurship Development Policy in 2010. This because, based on the 2010 Graduate Tracer Study, there is a low involvement (5.5 percent) of graduates in entrepreneurship, compared to employment in other sectors.This warrants a study to explore the factors influencing a graduate to become agro-entrepreneur.This study aims to identify these factors and also the characteristics of what actually make an agro-based graduate entrepreneur. In-depth interviews are conducted with twelve graduate agro-based entrepreneurs.The entrepreneurs are also requested to rate the importance of various triggering factors which are identified by previous studies. The factor rating results reveals that relatively, the most important factors are interest, satisfaction of being an entrepreneur, a sense of contribution to the society, generic skills (leadership, problem-solving, creativity and innovation, analytical, time and group management), social networking and taking-up of entrepreneur courses (after completing undergraduate studies); whereas, formal entrepreneur education, either at the degree, diploma or certificate level, is the least important. Results of in-depth interviews reveal that the characteristics of a graduate agro-based entrepreneur include those such as the right attitude, open mindedness, willingness to learn and face challenges, diligence, and good social networking

Cosmological Information in Weak Lensing Peaks

Recent studies have shown that the number counts of convergence peaks N(kappa) in weak lensing (WL) maps, expected from large forthcoming surveys, can be a useful probe of cosmology. We follow up on this finding, and use a suite of WL convergence maps, obtained from ray-tracing N-body simulations, to study (i) the physical origin of WL peaks with different heights, and (ii) whether the peaks contain information beyond the convergence power spectrum P_ell. In agreement with earlier work, we find that high peaks (with amplitudes >~ 3.5 sigma, where sigma is the r.m.s. of the convergence kappa) are typically dominated by a single massive halo. In contrast, medium-height peaks (~0.5-1.5 sigma) cannot be attributed to a single collapsed dark matter halo, and are instead created by the projection of multiple (typically, 4-8) halos along the line of sight, and by random galaxy shape noise. Nevertheless, these peaks dominate the sensitivity to the cosmological parameters w, sigma_8, and Omega_m. We find that the peak height distribution and its dependence on cosmology differ significantly from predictions in a Gaussian random field. We directly compute the marginalized errors on w, sigma_8, and Omega_m from the N(kappa) + P_ell combination, including redshift tomography with source galaxies at z_s=1 and z_s=2. We find that the N(kappa) + P_ell combination has approximately twice the cosmological sensitivity compared to P_ell alone. These results demonstrate that N(kappa) contains non-Gaussian information complementary to the power spectrum.Comment: 24 pages, 12 figures, 14 tables.

Wavenet based low rate speech coding

Traditional parametric coding of speech facilitates low rate but provides poor reconstruction quality because of the inadequacy of the model used. We describe how a WaveNet generative speech model can be used to generate high quality speech from the bit stream of a standard parametric coder operating at 2.4 kb/s. We compare this parametric coder with a waveform coder based on the same generative model and show that approximating the signal waveform incurs a large rate penalty. Our experiments confirm the high performance of the WaveNet based coder and show that the speech produced by the system is able to additionally perform implicit bandwidth extension and does not significantly impair recognition of the original speaker for the human listener, even when that speaker has not been used during the training of the generative model.Comment: 5 pages, 2 figure
