Abstract:
Thermoeconomic models, combining the concept of cost in economics and the concept of exergy in thermodynamics, provide the ability to optimize complex power generation systems to achieve the best balance between thermodynamic efficiency and economic cost. In this paper, a parametric analysis was carried out based on the method of calculating the unit exergy cost, as well as exergo-economic studies and cost sensitivity studies on the exergy of the cycle of a gas turbine power plant. The mathematical models of mass, energy, effort, and economy were created and presented. Thermodynamic properties

Abstract:
This manuscript presents an advanced exergo-economic analysis of a waste heat recovery system based on the organic Rankine cycle from the exhaust gases of an internal combustion engine. Different operating conditions were established in order to find the exergy destroyed values in the components and the desegregation of them, as well as the rate of fuel exergy, product exergy, and loss exergy. The component with the highest exergy destroyed values was heat exchanger 1, which is a shell and tube equipment with the highest mean temperature difference in the thermal cycle.

Abstract:
This research presents the energy, exergy, economic, and environmental assessment, and multi-objective optimization of a flash-binary geothermal CCHP cycle. A sensitivity analysis of production well inlet temperature and cooling to power flow ratio on exergetic, economic, and environmental parameters was conducted. Furthermore, the effects of the inflation rate and plant working hours on economic parameters were investigated. Results showed that increasing the production well inlet temperature harms exergy efficiency and exergetic performance criteria and results in a gain in exergo-environmen

Abstract:
This paper reviews the fundamentals of the Exergy Cost Theory, an energy cost accounting methodology to evaluate the physical costs of products of energy systems and their associated waste. Besides, a mathematical and computationally approach is presented, which will allow the practitioner to carry out studies on production systems regardless of their structural complexity. The exergy cost theory was proposed in 1986 by Valero et al. in their “General theory of exergy savings”. It has been recognized as a powerful tool in the analysis of energy systems and has been applied to the evaluation of

Abstract:
Based on the structural theory of thermo-economics, a 600 MW unit was taken as an example. An integration system which uses fuel gas heat and solar energy as a heat source for post-combustion carbon capture was proposed. The physical structure sketch and productive structure sketch were drawn and a thermo-economics model and cost model based on the definition of fuel-product were established. The production relation between units was analyzed, and the composition and distribution of the exergy cost and thermo-economic cost of each unit were studied.

Abstract:
Existing methods of exergoeconomic analysis and optimization of energy systems operate with single average or marginal cost values per exergy unit for each material stream in the system being considered. These costs do not contain detailed information on (a) how much exergy, and (b) at what cost each exergy unit was supplied to the stream in the upstream processes. The cost of supplying exergy, however, might vary significantly from one process step to the other. Knowledge of the exergy addition and the corresponding cost at each previous step can be used to improve the costing process. This p

Exergy is a thermodynamic quantity capable of measuring the conversion of material and energy flows into comparable terms based on the capacity of such flows to generate mechanical work as a useful effect and identifying and quantifying the thermodynamic inefficiencies of a generic process by means of the exergy destruction term. Because of its properties, an exergy is a convenient tool for the calculation of the global resource consumption of both natural and engineering processes. Therefore, there are different exergy-based approaches. Every exergy-based approach has its advantages and its

Abstract:
Desalination is one of the proposed methods to meet the ever increasing water demands. It can be subdivided into two broad categories, thermal based desalination and electricity based desalination. Multi-effect Distillation (MED), Multi-Stage Flashing (MSF), Membrane Distillation (MD) fall under former and Reverse Osmosis (RO), Electro-Dialysis (ED) fall under later. MD offers an attractive solution for seawater as well as brackish water distillation. It shows highly pure yields, theoretically 100% pure. The overall construction of a MD unit is way simpler than any other desalination systems.

Stand-alone hybrid energy systems are an attractive option for remote communities without a connection to a main power grid. However, the intermittent nature of solar and other renewable sources adversely affects the reliability with which these systems respond to load demands.

Cigarette smoking presents with considerable health risks and induces high costs on healthcare resources. People continue to smoke cigarettes in the face of adversity because they contain nicotine, which is highly addictive. Nicotine is a stimulant that exerts its effects within the brain by acting at nicotinic acetylcholine receptors (nAChRs). nAChRs are located in areas of the brain involved in reward processing, motivation, and cognitive control, which results in disruptions to behaviour when nicotine addiction has developed. Disturbances to the brain and behaviour are particularly evident

The Exergy Cost Theory (ECT) is a technique extensively applied to optimizing, diagnosing and designing energy systems. But, despite of its wide applications it has its limitations. Such limitations have to do partly with the application to discrete systems solely and partly with the cost allocation problem. Thus in the present paper we go a step further in the scope of the ECT and propose to enlarge its applicability to continuous systems. Essentially, this is carried through by taking the concept of the exergy cost to a microscopic point of view. To put it another words, the exergy costs are

Abstract:
White-tailed deer (WTD) can exert substantial impacts on the ecosystems in the Southeastern United States, particularly by overabundant WTD populations that are sheltered from recreational hunting pressure such as those in the National Parks. Information on WTD abundance and density is indispensable for science-based WTD population management. WTD populations in Vicksburg National Military Park (VICK) have not been surveyed since 2010. Management of WTD populations has been challenged by the lack of reliable, cost-effective methods, such as a deer visual count-density calibration coefficient,

Abstract:
Do targeted transparency interventions reduce corrupt behavior when corrupt actors are few and politically influential; their behavior imposes small costs on numerous individuals; and corrupt behavior is difficult to observe? Results from a study of informal audits and text messages to parents, meant to curb corruption in the School Meals Program of Colombia, suggests that they can. Theory is pessimistic that transparency interventions can change the behavior of actors who exert significant influence over supervisory authorities. Moreover, inherent methodological obstacles impede the identific

Abstract:
The engineering behavior of frozen soils is critical to the serviceability of civil infrastructure in cold regions. Among various geophysical techniques, electrical resistivity imaging is a promising technique that is cost effective and provides spatially continuous subsurface information. In this study, under freeze–thaw conditions, we carry out lab–scale 1D electrical resistivity measurements on frost–susceptible soils with varying water content and bulk density properties. We use a portable electrical resistivity meter for temporal electrical resistivity measurements and thermocouples for t

Abstract:
1.1 Macroeconomic summary In September, headline inflation (11.4% annually) and the average of core inflation indicators (8.6% annually) continued on a rising trend, and higher increases than expected were recorded. Forecasts increased again, and inflation expectations remained above 3%. Inflationary surprises in the third quarter were significant and widespread, and they are the result of several shocks. On the one hand, international cost and price shocks, which have mainly affected goods and foods, continue to exert upwards pressure on national inflation. In addition to these external suppl

Abstract:
While inflation fell significantly in 2024, it continues above the 3% target. However, monetary policy measures and corrections in particular factors that exert upward price pressures have helped direct inflation toward the objective. Economic activity continues to recover and is expected to continue growing. The monetary policy interest rate is compatible with the convergence of inflation to its 3% target and the gradual recovery of economic growth toward more sustainable levels. Inflation has fallen significantly, from 9.3% in 2023 to 5.2% in 2024. During this year and into the next, inflati

Abstract:
Inflation continues to fall, but it is above the 3% target, and it is projected to continue falling until it reaches it in 2025. Economic growth is low, but it would recover, and by 2025, economic activity would reach a path that can be sustained over time without causing unwanted changes in inflation, employment, or the external balance. The current monetary policy interest rate is compatible with the convergence of inflation to the target in 2025 and with the recovery of economic growth in the next two years. • Annual inflation has been decreasing for a year and is projected to continue, wit
