This paper uses a real options approach to examine the impact of ramping rate restrictions imposed on hydro operations to protect aquatic ecosystems. We consider the effect on hydro plant value in order to inform policy decisions. A novelty of the paper is in examining the optimal operation of a prototype hydro power plant with electricity prices modelled as a regime switching process. We show ...

A coordinated strategy between wind and reversible hydro units for the mid-term that reduces the imbalance of wind power and improves system efficiency is proposed. A stochastic mixed integer linear model is used, which maximizes the joint profit of wind and hydro energies and Conditional Value at Risk (CVaR), where CVaR is the tool utilized to model risk. The offering strategies studied are: i...

The use of digital information in geological fields is becoming very important. Thus, informatization in geological surveys should not stagnate as a result of the level of data accumulation. The integration and sharing of distributed, multi-source, heterogeneous geological information is an open problem in geological domains. Applications and services use geological spatial data with many featu...

With the advancements of technology in era big data and artificial intelligence, IoT (Internet Things) has a major role for purpose monitoring natural disasters like landslides. Landslides are catastrophic disaster worldwide that alter from terrain to terrain. In pursuit saving communities endangered by landslides, many techniques practiced. This paper is survey landslide adapted different part...

1-introduction one of the problems that is important in the waste management is the topic of waste rural landfill site selection and latex resulting from that in rural areas. the latex can be because groundwater pollution the contamination vulnerability and groundwater protection assessment has proved to be an effective tool for the delineation of protection zones in area affected by groundwate...

Ground-penetrating mapping radar allows fo r the three-dimensional reconstruction of ancient landscapes by interpreting geological horizons associated with archaeological sites. When the geological framework of a site can be placed in both time and space, ancient environments and people’s usage and adaptation to landscapes can be studied. In coastal Portugal late Ice Age people discarded stone ...

Preserving the hydration status means to balance daily fluids and salt losses with gains, where depend on several physiological environmental factors. Especially for athletes, these could be relevant negatively influence performance: therefore, their hydro-saline must preserved personalized pre- rehydration plans all along performance period. Scientific literature in this field is mainly dedica...

Sarvak formation, with the middle cretaceous (Cenomanian) age, is one of the stratigraphic units of the Bangestan group in the southern Iran. The carbonate rocks of this formation form the reservoir rock in the study field. Generally, Sarvak formation is subdivided into three members including Mishrif, Khatiyah, and Maddud in the Persian Gulf, and the average thickness of the reservoir unit (i....
