In this chapter, design and stability analyses of direct model reference control system based on wastewater treatment plant are addressed. The purpose of controller design includes input saturation control and two‐level control system with fuzzy supervisor control. The wastewater treatment plant is a highly uncertain non‐linear system and the plant parameter are unknown, therefore controller design are under those condition.

In the first stage, the feasibility of using the waste materials from coal power plants (i.e., coal slag) and landscapes (i.e., wood chip and compost) as packing media in various biofiltration systems for ammonia (NH3) removal was investigated. In the second stage, the optimized biotrickling system packed with coal slag was employed to investigate the effects of inlet concentration on NH3 treatment performance. A complete NH3 removal was achieved...

Today manufacturing stages in electronic device industry of wide-scale production can be restricted due to the high costs resulting from energy consumption, the use of organic solvents, production of hazardous intermediates, and formation of waste products leading to environmental pollution and several biological risks which damage society’s ability to sustain the planet for future generations. As recycled material resource based on iron oxide,...

Empty fruit bunch of oil palm tree (EFBOPT), solid waste of palm oil industries, is potential for raw materials of biofuel especially bioethanol production because of its cellulose and hemicellulose contents. There are four steps to produce bioethanol, called the second generation bioethanol, from EFBOPT or other lignocellulosic materials. The steps are (a) pretreatment of lignocellulose biomass into cellulose/hemicellulose, (b) hydrolysis of cellulose/hemicellulose...

Excess nitrogen components must be removed from wastewater to protect the quality of the water bodies that it will be eventually discharged to. A conventional wastewater treatment system for nitrogen removal is often involved with two processes, nitrification and denitrification. Nitrification is mostly achieved by complete oxidation of ammonium (NH4+) to nitrite (NO2-) by the appropriate aerobic bacteria and then oxidation of the nitrite to nitrate...

Particle. physical and chemical properties play a key role in determining the health effects associated with PM emissions. Smaller particles can penetrate deep inside the alveolar regions of lungs. Bio-available particulate-bound compounds pose serious health problems. WCOB had lower PNC compared to that of ULSD. However, WCOB had a higher fraction of nucleation mode particles relative to that of ULSD, and therefore, a large fraction of PM emitted...

Explore the benefits of a mindful approach to life Cutting-edge studies in neuroscience have in recent years proved what many doctors, therapists and other health professionals had long suspected: simple, repetitive tasks, performed with focus and attention - mindfulness, in other words - can not only quieten our noisy thought processes and help us relax but also improve our outlook on life and protect us against a range of life-threatening illnesses. A...

40 Wochen dauert es, bis ein menschliches Baby im Bauch der Mutter heranwächst. Anna Blix schaut sich diese Zeitspanne der menschlichen Schwangerschaft an und stellt parallel dazu in jeder dieser Wochen andere Lebewesen vor, die gerade ihre Nachkommen zur Welt bringen. So hat das Bakterium E. coli sich innerhalb von 20 Minuten verdoppelt. Das Graue Riesenkänguru ist nur fünf Wochen schwanger, dann kommt das Baby in der Größe einer Bohne auf die...
