The moderating effect of firm size: Internationalization of small and medium enterprises (SMEs) in the manufacturing sector
No full textPrevious research on the internationalization of small and medium enterprises (SMEs) explored the
relationship between adoption of global orientation and competitive advantage, management attitude,
and international knowledge and experience. However, there was a difference in opinion between those
arguing that there is a positive relationship between these variables and others who contended that
there is moderating effect of size on the internationalization. Within this context, this study sets out to
further the discussion by comparing the global orientation of SMEs in Malaysia with their different level
of size. In doing so, it draws upon the findings of survey of 300 internationalized enterprises located in
northern region of Malaysia. The results suggest that size functions as moderating factor for
internationalization only for relatively smaller firms. It has its biggest impact when relatively smaller
SMEs acquire international knowledge and experience. They also note implications for managers and
policy makers
Unified Access to Heterogeneous Resources in a Distributed Library Consortia Environment: Challenges and Opportunities
No full textLibrary consortia in today’s digital age are quite different from that of library networks in yester years. The main reason is that the resources that are shared in today’s consortia environment are predominantly in electronic form such as electronic journals and databases. Hence the technology and associated tools to support sharing the electronic resources are also important components for the success of any library consortia. It is essential that each participating libraries of a consortium is equipped with necessary and sufficient technology to support sharing the resources across. Unified access to heterogeneous resources is one of the greatest challenges that library consortia face. The paper looks at the unified access system to search heterogeneous resources in a distributed library environments. The paper discusses the challenges and opportunities of unified access systems by looking at some of the major international initiatives
Temperature measurement of overlapped fiber Bragg grating sensors in a series fiber sensor network
No full textFiber Bragg Gratings (FBGs) in a sensor network have been widely used for structural health and process monitoring. The number of FBGs with distinct wavelength that can be used in such a sensor network is limited by the bandwidth of the laser used. FBGs, with overlapping spectra cannot be interrogated in a series sensor network since they shadow each other. Methods like time division multiplexing (TDM), code division multiplexing (CDM) have been used to interrogate overlapped FBGs. TDM is limited by the power budget system and CDM is limited by the number of FBGs can be used. We propose a neural network based Spectral Division Multiplexing (SPDM) scheme, to monitor overlapped FBGs in a series fiber sensor network
Dynamic Load Prediction in Offshore Wind Turbines
No full textThe rapid development of the wind industry over the past few years has pushed turbine manufacturers to meet the growing energy demands by designing and producing large scale wind turbines.This also means development of larger monopile foundations for the foundation designers in the case of offshore wind turbines.\ Generally, the turbine tower and monopile are modeled together and the loads from the rotor-nacelle assembly are provided by turbine manufacturers.\ The offshore industry is now showing more interest in extracting the loads from the top mass by developing their own tools in order to reduce the dependency on the manufacturers. In order to aid in this process, the present master thesis aims to develop a linear model based on the concept of Dynamic Substructuring which employs a set of equations to compute the interface forces using the kinematics.\ Furthermore, the developed prediction model is used to analyze the loads occurring at the interface between the rotor-nacelle assembly and the tower for different wind speeds and wind conditions.Consequentially, the model was found to produce acceptable loads at higher wind speeds for selected degrees of freedom at the interface while failing to do the same for other degrees of freedom.The results in time domain were converted to the frequency domain to analyse the resonance.The influence of resonance on the interface degrees of freedom was found to be higher at wind speed below the rated condtion.\ These findings can be used as a basis to conduct further investigations into the application of numerical integration concepts to aeroelastic structures.Electrical Engineering | Sustainable Energy Technolog
