Modeling and forecasting long-term natural gas (NG) consumption in Iran, using particle swarm optimization (PSO)

The gradual changes in the world development have brought energy issues back into high profile. An ongoing challenge for countries around the world is to balance the development gains against its effects on the environment. The energy management is the key factor of any sustainable development program. All the aspects of development in agriculture, power generation, social welfare and industry in Iran are crucially related to the energy and its revenue. Forecasting end-use natural gas consumption is an important Factor for efficient system operation and a basis for planning decisions. In this thesis, particle swarm optimization (PSO) used to forecast long run natural gas consumption in Iran. Gas consumption data in Iran for the previous 34 years is used to predict the consumption for the coming years. Four linear and nonlinear models proposed and six factors such as Gross Domestic Product (GDP), Population, National Income (NI), Temperature, Consumer Price Index (CPI) and yearly Natural Gas (NG) demand investigated.

Exploring 'Samoaness' in the Samoan language film The Orator (O Le Tulafale)

The Pacific nation of the Independent Samoa (formerly Western Samoa)  is not known for having a developed film industry.   In 2011, a Samoan languge film called The Orator (O le Tulafale) placed the spotlight on Samoa, its people, and the Samoan culture when it became the country’s first ever film to be accepted into major international film festivals such as the 68th Venice Film Festival.  Samoans the world over have embraced the film for its richness, compassion, and authenticity. Yet at times, the film portrays the Samoan culture as harsh and cruel.   Samoans are usually quick to criticise negative portrayals of their culture but the thousands of comments on the film’s official Facebook page show otherwise.  From April 2011 to March 2012, there were only 11 comments criticising the film on Facebook, and these criticisms were denounced as ‘un-Samoan’. This raised the question as to why Samoans did not react to the unflattering portrayals of their culture, but instead react against legitimate criticisms of the film.  By using Foucault’s concept of heterotopia and the Samoan narrative structure of fāgogo, a heterotopia space and a utopia space are created in which past memories confirming Samoan cultural identity and bonds to the culture are evoked and are (re)experienced by Samoans while viewing the film.  Thus the film’s ability to encourage this is what Samoans praise rather than the actual film.  

Survery and simulation of energy use in the European building stock

the work towards increased energy efficiency. In order to plan and perform effective energy renovation of the buildings, it is necessary to have adequate information on the current status of the buildings in terms of architectural features and energy needs. Unfortunately, the official statistics do not include all of the needed information for the whole building stock.   This paper aims to fill the gaps in the statistics by gathering data from studies, projects and national energy agencies, and by calibrating TRNSYS models against the existing data to complete missing energy demand data, for countries with similar climate, through simulation. The survey was limited to residential and office buildings in the EU member states (before July 2013). This work was carried out as part of the EU FP7 project iNSPiRe.   The building stock survey revealed over 70% of the residential and office floor area is concentrated in the six most populated countries. The total energy consumption in the residential sector is 14 times that of the office sector. In the residential sector, single family houses represent 60% of the heated floor area, albeit with different share in the different countries, indicating that retrofit solutions cannot be focused only on multi-family houses.   The simulation results indicate that residential buildings in central and southern European countries are not always heated to 20 °C, but are kept at a lower temperature during at least part of the day. Improving the energy performance of these houses through renovation could allow the occupants to increase the room temperature and improve their thermal comfort, even though the potential for energy savings would then be reduced.
