The 2nd generation plants producing ethanol from lignocelluloses demand risky and high investment costs. This paper presents the energyand economical evaluations for integrating lignocellulose in current 1st generation dry mill ethanol processes, using filamentous fungi. Dry mills use grains and have mills, liquefactions, saccharifications, fermentation, and distillation to produce ethanol, whi...

This study aims at studying the environmental effects of desalination byproducts and the cost analysis of desalination systems. Focus was made on the two widespread techniques of seawater desalination; the Multistage Flash (MSF) System and Reverse Osmosis (RO) system. These two technologies of thermal and membrane desalination have a substantial history and their industry is well established. M...

As computing technologies continue to rapidly advance since the last two decades, the knowledge economy has become an important part of the overall world economy. In addition to its significantly contribution to economy growth, computing technologies also have profound impact on many aspects of society. A panel discussion was held at the 21st ISCA International Conference on Computer Applicatio...

financial and economic analysis of investment constitute an essential part of the decision making process. in this paper the feasibility of executing wastewater projects has been assessed using techniques of engineering economics including economic and financial analyses. primarily, the economic and financial assessments of a specific project in kalateh-khij city, with a population of five thou...

Since the work of André Martinet back in the 60’s [7], the notion of ‘economy’ has been accepted as one of the main principles underlying the organization of phonological inventories (hereafter PI). This principle, also named MUAF (‘Maximal Use of Available Features’) by John Ohala [8], states that PI are organized along a few phonetic dimensions that they tend to maximize in terms of number of...

In this paper, we have continued doing a research project which had done previously. Three types of power plants include an Organic Rankine Cycle (ORC), a Dual-Fluid-Hybrid (DFH) and a single-fluid hybrid-fueled (HYB); were re-modeled. After model validation, thermodynamic studies and exergy analysis were extended for the defined cases using the first and second laws of thermodynamics. Then the...
