Multi-objective Optimization of PV-SOFC-GT-Electrolyser Hybrid System

This study shows the design of a new hybrid power generation system, photovoltaic panel (PV)–coupled solid oxide fuel cell (SOFC) and gas turbine (GT)–electrolyser. Three objectives (cost, pollutant emissions, and reliability), which are usually in conflict, are considered simultaneously. The design of a hybrid system, considering the three mentioned objectives, poses a very complex problem of o...

Computed tomography anomalies associated with isolated hypoparathyroidism

Hypocalcemia due to chronic hypoparathyroidism presents with nonspecific symptoms. However, if untreated, hypocalcemia may affect neurological, cognitive, muscular, and cardiac function. Computed tomography (CT) findings may confirm a diagnosis of chronic hypoparathyroidism. Although autoimmune acquired hypoparathyroidism is a rare disease, early diagnosis and treatment are critical for avoidin...

Astrometric Solar-System Anomalies

There are at least four unexplained anomalies connected with astrometric data. Perhaps the most disturbing is the fact that when a spacecraft on a flyby trajectory approaches the Earth within 2000 km or less, it often experiences a change in total orbital energy per unit mass. Next, a secular change in the astronomical unit AU is definitely a concern. It is increasing by about 15 cm yr−1. The o...

Identification of Geochemical Anomalies Using Fractal and LOLIMOT Neuro-Fuzzy modeling in Mial Area, Central Iran

The Urumieh-Dokhtar Magmatic Arc (UDMA) is recognized as an important porphyry, disseminated, vein-type and polymetallic mineralization arc. The aim of this study is to identify and subsequently determine geochemical anomalies for exploration of Pb, Zn and Cu mineralization in Mial district situated in UDMA. Factor analysis, Concentration-Number (C-N) fractal model and Local Linear Model Tree (...
