This paper describes the results from a performance comparison of different types of HVAC systems in a low energy residential building. There were five different HVAC systems which were investigated and evaluated: Ground Couple Heat Pump (GCHP); Ground Water Heat Pump (GWHP); Air-to-Water Heat...

The experiments of reforming the methane of coke-oven gas with steam were performed. The effects of the thermodynamic factors, such as the H2O/CH4 ratio, the conversion temperature (T) of methane and the reaction time (t), on the methane conversion rate have been investigated. The experimental...

Among billions of Internet enabled devices that are expected to surround us in the near future, many will be resource constrained, i.e., will have limited power supply, processing power and memory. To cope with these limitations, the Constrained Application Protocol (CoAP) has been recently...

The new generations of mobile networks will require economical and viable solutions in order to meet the promises raised by scientists. In this article, the authors overview the available research activities and present an architecture for DAS and femtocells and a mathematical model analyzing...

Net neutrality is defined as the concept in which Internet service providers are obliged to treat all data streams equally, independent of which application, service, device, sender or receiver is involved. They are as such forbidden to block, throttle or alter data traffic over their networks....

Machine-to-Machine (M2M) communications refers to the automate exchange of information between devices for control and monitoring applications. This type of communication is not new since automated systems have been present for more than three decades. However, miniaturization of device's size,...

It is beyond doubt that the exponential growth in available data will serve many purposes and will be provided for and to many users. To meet the wide range of needs, a business handling data system must meet different criteria. This paper provides an a both qualitative and quantitative...

Transportation played a significant role in energy consumption and pollution subsequently. Caused by the intense growth of greenhouse gas emission, efficient and sustainable improvement of the transportation sector has elevated the concern in many nations including Malaysia. Bioethanol is an...

This work aims to contribute to the debate on the fixed wireless versus fixed line broadband access solutions by focusing on scenarios offering Gbps level broadband access. More specifically, we performed a techno-economic analysis on the cost, performance (in the term of download speed) and...

The last years have witnessed a surge in research papers focusing on the visions, enabling technologies, use cases, business models, and applications of 6G Wireless Communications Networks. While the technological advancements have garnered significant attention, the technoeconomic feasibility...
