Introduction: Energy economics and financial markets
No full textEnergy issues feature frequently in the economic and financial press. It is argued that the importance of energy production, consumption and trade and raises fundamental economic issues that impact the global economy and financial markets. Specific examples of daily energy issues stem from various countries and can often be related to economics and finance. It is shown that energy economics and financial market research issues can be grouped under the themes of supply and demand, environmental impact and renewables, energy derivatives trading, as well as finance and energy

Sector and Country Effects of Carbon Reduction and Firm Performance
No full textPrevious studies have indicated a positive association between carbon reduction and firm performance. Using a dataset covering firms across 10 sectors and 53 countries over the period 2004–2019, we add to the literature by showing the differences between sectors and various groupings of countries on carbon reduction and firm performance in terms of the return on assets, the return on equity and the return on sales, as well as the Tobin’s Q and the current ratio. The services sector shows a positive result in relation to most of the corporate financial performance variables. The results also provide evidence for a negative relationship for agricultural and mining firms. The findings indicate that differences in carbon reduction are limited when allowing for various ways of grouping countries

Renewable energy in Indonesia:Integrating Human Capital and Money Flows
No full textIn developing countries, renewable energy plays an important role. Applying the available natural resources in conjunction with a technology push may help to solve energy sourcing issues and to develop remote areas in such countries. Whereas many large-scale projects have been taking place, small-scale projects that bring a technology push are rare to find. This study investigates the possibilities of implementing renewable energy sources in the form of Mobile Biodiesel. We construct a conceptual model in which local economic development is infused with money flows and group entrepreneurship aspects in order to realise the implementation of this energy source. Our field research was conducted in remote villages in the Pulang Pisau area in Central Kalimantan, Indonesia. The results indicate a large shortage of technical, managerial, and financial knowledge and skills in the remote villages, resulting in a lack of human capital. Furthermore, the occurrence of frequent electricity blackouts with long durations disturbs the local communities in their daily activities. To address these problems, this study argues for the integration of community empowerment, social capital, social franchising and especially group entrepreneurship in combination with a transparent financial system on the flow of money while introducing a new technology. Although our model is based on empirical results in a remote Indonesian area and on the Mobile Biodiesel technology, the model is also applicable in developing areas throughout and it can be integrated with other renewable energy technologies
Floating WIM Threshold Concept for Truck Weight Enforcement
No full textWeigh stations are the primary weight compliance checkpoints for commercial trucks. In the past several decades, states have used weigh-in-motion (WIM) technology to reduce delay and increase enforcement on overweight vehicles. This study offers a detailed analysis of weigh station systems and presents floating-threshold algorithms to improve the efficiency of WIM equipped weigh stations.
This research evaluates weigh station design and operational parameters using queueing theory and found that WIM technology not only enhances the effectiveness and efficiency of weigh station operations but also largely reduces travel delay for trucking companies. The effects of truck demand, truck weight distribution, static scale service time, WIM accuracy, and sorting threshold on weigh station operations have been analyzed. The author shows the importance of transponders in a WIM mainline weigh station operation. The author also proves that the increase of storage spaces within a weigh station may largely increase truck travel delay and does not significantly improve weigh station operations.
This research focuses on the development of floating-threshold algorithms. Since the number of trucks, particularly heavy trucks, has increased rapidly in recent decades, many weigh stations cannot meet the demand even when equipped with WIM systems. This problem is complicated by the fact that truck demands, truck weight distribution, and static scale service time vary by time of day and day of week. The author designed floating-threshold algorithms to automatically adapt to high truck demand and the varying of truck demand, truck weight distribution, and static scale service time, over time. When the queue at the weigh station is long, the threshold value is increased so as to avoid the closure of the weigh station while still catching the worst weight limit offenders. When the queue is short, the threshold value is lowered to increase the number of trucks inspected. Both the traditional fixed-threshold strategy and two floating-threshold strategies were modeled and tested using a microscopic simulation model. The results show that floating-threshold strategies are both more effective in weight enforcement and more efficient for heavy traffic flow and high-variance environments. The finding that different floating-threshold strategies have different effects indicates that it is necessary to make a further study on floating-threshold algorithms
The Impact of Tourism on Curacao's Economy: A Scenario Approach
No full textCuraçao is an autonomous countrywithin the Kingdom of the Netherlands. The governmentwants to support tourism development. However,various development strategies are possible. This articlepresents four scenarios of marketing and investmentstrategies that will affect the number of tourists fromThe Netherlands and North America (USA and Canada)in different ways. A multiplier model was used to calculatethe economic impacts of the four scenarios. Bydoing so, this article shows how the government’s decisionto support particular marketing and investmentstrategies may have certain outcomes for the number ofjobs in Curaçao’s tourism industry

No full textModel Validation and New Water Control Strategies in Drinking Water Treatment Plant Wim Mensink
No full textStimela is an environment for standardized mathematical models of drinking water treatment processes. It can be used to predict the future water treatment situation which may happen or change. In water treatment plant Wim Mensink, the Stimela model train was set up to compare with other alternative water control strategies. Before starting the work of developing new water control strategies with Stimela model, Stimela model for Wim Mensink must be validated so that the model can be seen as a reliable and stable tool for the next work. Before the validation work, the current water control strategy for the treatment process needs to be investigated clearly to fulfil all the input control information is correct. Besides this, an experiment for obtaining the measured results of pellet diameters over different layers was performed in Wim Mensink. The validation work starts with single pellet softening process for three different reactors over first month from January 20th to February 20th. The fluidized bed height, pressure drop over total height of reactor, pellet diameters and porosities are validated. After that, the validation work is integrated with whole water treatment system to prove the function of pellet softening reactor and the four important water quality parameters over two important locations (after weir aerator location and final RO mixing location). The validated results of softening process are analysed by the relative error way to prove the reliability of the model results compared with measured results. The final step of the thesis work is developing the new water control strategies to optimize the current control plans of Wim Mensink. Five different water control strategies are put forward. They can be either reached separately according to their own advantages and limitations or fulfil with a step by step order as a whole optimization process. Moreover, the other water control strategies developed by engineering consultancy company DHV are evaluated here with Stimela model so that they can be proved reliable and achievable. In the future, the application of Stimela model will be spread over all the drinking water treatment plants in the Netherlands and contributes to the central automated control as a drinking water treatment operator training simulator.Sanitary EngineeringWatermanagementCivil Engineering and Geoscience
