Abstract:
This research will discuss a strategy of frequency control at micro hydro power plant using Capacitive Energy Storage (CES). CES is a device that can store and release energy quickly. To optimize CES performance, proper tuning is required to optimize CES performance. To obtain optimal CES parameter on micro hydro, artificial intelligence method based on Imperialist Competitive Algorithm (ICA) is used. Proportional Integral Derivative Controller (PID) is still a controller that can not be separated from the system, therefore in this research will be combined with CES as the main controller for

Fuzzy control, based on traditional Proportional-Integral-Derivative (PID) control, is used to improve the management of a hydro-junction’s sluice scheduling. In this study, we combined the PID and Fuzzy control theories and determined the PID parameters of the fuzzy self-tuning method of a hydro-junction’s sluice. A fuzzy self-tuning PID controller and its algorithm were designed. In hydro-junction sluice control, the Fuzzy PID controller can modify PID parameters in real-time, resulting in a more dynamic response.

When supplied with adequate infiltration laws, this model can provide useful information in surface hydrology.

Abstract Excessive pressure in water distribution networks (WDNs) may lead to undesirable effects, such as increased pipe failure rate and leakages. Pressure management (PM) techniques are indeed attractive to address these issues, reducing energy and water losses. Among the most recent PM techniques, pumps working as turbines (PATs) can be employed to both control pressure and recover energy. However, finding the best location, setting, and number of PATs to maximize both leakage reduction and energy production within a WDN is particularly challenging due to the severe nonlinearity of the pro

Since the deregulation of the Nordic electricity market in 1996, electricity has become one of the most traded commodities in the Nordic region. The electricity price is characterized by large fluctuations as the supply and demand of electricity are seasonally dependent. The main interest of the hydro power producers is to assure that they can sell their hydro power at an attractive rate over time. This means that there is a demand for hedging against these fluctuations which in turn creates trading opportunities for third party actors that offer solutions between consumers and producers. Telg

The gain values of the PID controllers were tuned using Ant Colony Optimization (ACO) technique with one percent Step Load Perturbation (1% SLP) in area 1. The Integral Square Error (ISE), Integral Time Square Error (ITSE), Integral Absolute Error (IAE) and Integral Time Absolute Error (ITAE) were chosen as the objective function in order to optimize the controller's gain values. The experimental results reported that the IAE based PID controller improved the system performance compared to other objective functions during sudden load disturbance.

In this work, Artificial Intelligence (AI) based Ant Colony Optimization (ACO) algorithm is proposed for Load Frequency Control (LFC) of interconnected multi–area hydrothermal power systems. Area 1&2 are thermal power systems and area 3 is a hydro power system, all the areas are interconnected through the appropriate tie-line. Thermal and hydro power plants are applied with reheat turbine and electric governor respectively. Investigated power system initially applied with conventional Proportional-Integral (PI) controller and controller parameters are optimized by using trial and error method considering Integral Time Absolute Error (ITAE) objective function. After that, the system is equipped with Proportional – Integral – Derivative (PID) controller and controller parameters are optimized by using ACO algorithm with ITAE objective function. The superiority of the proposed algorithm has been demonstrated by comparing conventional controller. Finally, The Simulation results of multi-area power system prove the effectiveness of the proposed optimization technique in LFC scheme and show its superiority over conventional PI controller.

Abstract:
AbstractReactive ion etching is a key technology in the production of advanced semiconductor devices with a resolution of down to sub-10-nm scales. Depending on the exact application, NF3, SF6 as well as complex fluoro(hydro)carbons are used to generate a plasma consisting of ions and other reactive species which converts silicon and its derivatives into volatile compounds. Recently, the development objectives of new etch gases have moved from pure performance to a more complex set of properties including low global warming potential (GWP) and compliance with regulation on fluoroorganic compounds (PFAS). The structure of fluorinated etch gases with low GWP incorporates chemically "weak spots" facilitating atmospheric degradation. The fragmentation in the energetic plasma environment can be predicted by computational methods, enabling the optimization of the ion composition for high etch rate or selectivity between different materials.

Abstract:
Several new routes to furans and to pyrroles have recently been put forward. Inspired by the Achmatowicz ring expansion, Patrick J. Walsh of the University of Pennsylvania developed (J. Am. Chem. Soc. 2008, 130, 4097) the oxidative rearrangement of 3-hydrox-alkyl furans such as 1 to the 3-aldehyde 2. José M. Aurrecoechea of the Universidad del País Vasco established (J. Org. Chem. 2008, 73, 3650) that cumulated alcohols, available by reduction of alkynes such as 3 with SmI2, rearrange under Pd catalysis, and then add to an acceptor alkene such as 4, to give the furan 5. Vladimir Gevorgyan of the University of Illinois at Chicago used (J. Am. Chem. Soc. 2008, 130, 1440) an Au catalyst to rearrange an allene such as 6 to the bromo furan 7. Fabien L. Gagosz of the Ecole Polytechnique, Palaiseau, also found (Organic Lett. 2007, 9, 3181) that an Au catalyst rearranged the eneyne 8 to the pyrrole 9. Azido esters such as 10 are readily prepared from the corresponding aldehyde by phosphonate condensation. Shunsuke Chiba and Koichi Narasaka of Nanyang Technology University demonstrated (Organic Lett. 2008, 10, 313) that thermal condensation of 10 with acetyl acetone 11 gave the pyrrole 12, while Cu catalyzed condensation with acetoacetate 13 gave the complementary pyrrole 14. Huan-Feng Jiang of South China University of Technology observed (Tetrahedron Lett. 2008, 49, 3805) that condensation of an acid chloride 15 with an alkyne 16, presumably to give the alkynyl ketone, followed by the addition of hydrazine delivered the pyrazole 17. Masanobu Uchiyama of RIKEN and Florence Mongin of the Université de Rennes 1 established (J. Org. Chem. 2008, 73, 177) that a pre-formed pyrazole 18 could be metalated and then iodinated, to give 19.

Full text
Abstract:
Many applications require primary information such as average fluxes as a prelude to more complex calculations. In water balance calculations one may be interested only in the average fluxes. For both cases the concept of effective conductivity is useful. The effective hydraulic conductivity is defined by where the angled brackets denote the expected value operator. The local flux fluctuation is defined by the difference qi(x) — (qi(x)). Its statistical properties as well as those of the velocity will be investigated in chapter 6. To qualify as an effective property in the strict physical sense, Kef must be a function of the aquifer’s material properties and not be influenced by flow conditions such as the head gradient and boundary conditions (Landauer, 1978). Our goal in this chapter is to explore the concept of the effective conductivity Kef and to relate it to the medium’s properties under as general conditions as possible. Additionally, we shall explore the conditions where this concept is irrelevant and applicable, the important issue being that Kef is defined in an ensemble sense, but for applications we need spatial averages. Several methods for deriving Kef will be described below. The general approach for defining Kef includes the following steps. First, H is defined as an SRF and is expressed with the aid of the flow equation in terms of the hydro-geological SRFs (conductivity, mostly) and the boundary conditions. The H SRF is then substituted in Darcy’s law and an expression in the form equivalent to (5.1) is sought. If and only if the coefficient in front of the mean head gradient is not a function of the flow conditions will it qualify as Kef. The derivation of the effective conductivity employs the flow equation. In steady-state incompressible flow, for example, Laplace’s equation is employed. Solutions derived under Laplace’s equation are applicable, under appropriate conditions, for other physical phenomena governed by the same mathematical model. For example, the electrical field in steady state is also described by Laplace’s equation.

However, due to the heterogeneity and complex multi-physics nature, high-fidelity physics-based forward simulation can be computationally intensive, creating a barrier to efficient reservoir management. A robust and fast optimization framework for maximizing the thermal recovery from EGS is needed. We developed a general reservoir management framework which is combining a low-fidelity forward surrogate model (fl) with gradient-based optimizers to speed up reservoir manag

Abstract:
The objective of this work is to establish a synthesis between modern methodology in the field of ship maneuvering and control theory using the example of hydrodynamic ship-bank interactions for a large tanker. Evolving technologies have paved the way for developing increasingly sophisticated modeling techniques to study ship flows. These tecnologies have made it possible to resemble Planar Motion Mechanism (PMM) tests in numerical simulations using Reynolds-averaged Navier-Stokes (RANS) equations. These advances give way for the numerical determination of hydrodynamic derivatives as present i
