One of the mechanisms ensuring the continuity of new behaviors is the creation of new habits. The main purpose of policy interventions, including education or economic incentives, is to create behaviors that are sustainable, such as recycling or optimizing water or energy consumption (gas or electricity) or, more simply, creating positive habits. Social researchers emphasize on the importance of the apparent need for a basic change in mindset and practice of consumption. The purpose of the present study was to investigate the consumption habits of household gas consumers with emphasis on consumption optimization. This study was carried out in Mazandaran province in November 2019. The sample consisted of 430 household subscribers of Mazandaran Province Gas Company. Survey method was used and a structured questionnaire was used for data collection. Descriptive and inferential statistics were used for data analysis. Research findings showed that home subscribers tend to optimize gas consumption. The average family culture, awareness of the negative consequences of gas consumption, awareness of policies of optimal gas consumption in the building and the personal efficiency of the respondents were at a good level, while the means of knowledge of gas consumption and satisfaction with gas company service was moderate level. The habit of optimizing gas consumption differed by occupation but it wasn’t different by gender and education. Also, the habit of optimizing gas consumption was positively correlated with age but was not significantly correlated with household income and gas price. The theoretical model was tested by structural modeling. And the relationships drawn in the theoretical model were corrected The results showed that knowledge of gas consumption has the greatest direct impact on the habit of gas consumption, while family culture has the most indirect effect on the habit of gas consumption. Overall, the results of the present study showed that knowledge had a positive effect on gas consumption optimization habits.

Persuading people especially of saving water resources is of paramount importance in our society. This requires a change in people's behavior as a component of the Islamic Republic's customs and conventions that in their turn should be discussed and analyzed. The issue of managing water resources and water consumption in the world and especially in our country that suffers from drought has priority and it necessitates the assistance of researchers in different fields such as sociology and communication. This has led us to examine the semiotics of the ads used by the ministry of energy and see how they could direct people to reform their habits in regard to water consumption. The persuasive structure and the strong and weak points of the ads are therefore analyzed. In other words, what counts is the nature of the sender's message not the receiver's reaction . The research has considered five posters related to water consumption that comprise persuasive measures. The results show that though persuasive measures have been used in the ads, there have been no purposeful and coherent planning of producing them. The most w

In urban road networks, traffic signals have been used to control vehicle movements in order to reduce congestion, improve safety, and enable specific straregies such as minimizing delays and improving environmental pollution. The optimization of signal control is at the heart of urban traffic. Using the optimization techniques in determining signal timing has been discused greatly for decades. Due to the fact that finding effective green times in signalised intersection cause complex differential functions, it is not possible to use derivative rules for analysis of this kind of problems. Due to complexity of the area control problems, new methods and approaches are needed to improve efficiency of signal control in a signalized road network such as meta-heuristic methods. In this paper the combination of genetic programming and genetic algorithm are applied to optimize signal timing. The proposed method uses existing traffic data to construct genetic network. The duty of genetic programming is to predict intersections delay for different timing and phasing of signals. All this process is done in MATLAB software. The comparisons show acceptable result of the proposed method. The major advantages of this method is the ability of genetic programming in producing a proper formula.

To provide clean water with a minimum energy consumption, in the current situation in particular, is of vital importance. Considering the fresh water scarcity and high expense of existing resources exploitation, combining the advantages of free solar energy with a cost effective design to produce fresh water becomes a great interest for many researchers. Desalination of sea water or brackish groundwater using renewable energies is one of the best climate change adaptation and mitigation strategies which is increasingly being supported and heavily financed in the neighboring countries. In our country, with regard to recent water crises, application of an integrated management strategy in resource management for optimizing efficiency in these two critical resources becomes exceedingly necessary. This research aims to provide a feasibility study guideline on techno-economic optimization of renewable desalination systems. It could be used for a sustainable water production for potable, industrial or agricultural sectors.
