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...

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,...

Adaptive cooling technique has been proposed previously, as an energy efficient strategy for a centralized HVAC system in a tropical environment. It served single or multi zone buildings by considering both the occupancy pattern (occupied and unoccupied periods) and the local weather conditions....

Domestic and industrial sludge generated at wastewater treatment facilities is considered a potential biomass source for producing biodiesel. However, transportation of large amounts of sludge from wastewater treatment facilities to a biorefinery is expensive. The objective of this paper is to...

A review of recent research that has been undertaken on the design and development of various solar distillation systems is reported. A techno-economic analysis is carried out to measure the cost of effectiveness of various distillation systems.

The paper presents a new thermochemical process for the production of isobutanol, which is an excellent biobased gasoline blendstock. The main feedstock for the process is glycerine, obtained as a byproduct in biodiesel production, being used together with methanol. The process was modeled in...

Conventional azeotropic distillation, consuming very high energy, is mostly used to produce high purity ethanol for renewable energy usage. In this study, the techno-economic comparison between azeotropic distillation (distillation followed by practical azeotropic distillation) and hybrid system...

An original proposal for the deployment of photovoltaic (PV) systems in offshore environments is presented in this paper. Crystalline PV panels are considered where they are deployed on pontoon type structures and there are six case study examples precedent practise of such deployments in lakes...

Shortcomings of transport network technologies were the main driver behind strong efforts of standardization organizations to develop control plane frameworks since 2001. Despite the findings of previous studies that the control plane framework deployment will lead to a 50 percent decrease in...
