Full textEn el contexto energético actual y particularmente en el lado del usuario, el concepto de sistema de gestión energética (EMS) se presenta como una alternativa apropiada para mejorar continuamente la eficiencia energética. Los EMSs en combinación con las tecnologías informáticas dan origen al concepto de iEMS, que además de soportar las funciones de los EMS, tienen la capacidad de modelar, pronosticar, controlar y supervisar los consumos energéticos. Su principal objetivo es el de realizar una mejora continua, lo más autónoma posible y predictiva de la eficiencia energética. Este tipo de sistemas tienen como núcleo fundamental el sistema de modelado y pronóstico de consumos (Load Modeling and Forecasting System, LMFS). El LMFS está habilitado para pronosticar el comportamiento futuro de cargas y, si es necesario, de generadores. Es sobre estos pronósticos sobre los cuales el iEMS puede realizar sus tareas automáticas y predictivas de optimización y supervisión. Los LMFS en el lado del usuario son el foco de esta tesis. Un LMFS en el lado del usuario, diseñado para soportar un iEMS requiere o demanda ciertas características que en otros contextos no serían tan necesarias. En primera estancia, los perfiles de los usuarios tienen un alto grado de aleatoriedad que los hace más difíciles de pronosticar. Segundo, en el lado del usuario, por ejemplo en la industria, el gran número de puntos a modelar requiere que el LMFS tenga por un lado, un nivel elevado de autonomía para generar de la manera más desatendida posible los modelos. Por otro lado, necesita un nivel elevado de adaptabilidad para que, usando la misma estructura o metodología, pueda modelar diferentes tipos de cargas cuya procedencia pude variar significativamente. Por lo tanto, los sistemas de modelado abordados en esta tesis son aquellos que no solo buscan mejorar la precisión, sino también la adaptabilidad y autonomía. En busca de estos objetivos y soportados principalmente por algoritmos de inteligencia computacional, procesamiento de señales y estadística, hemos propuesto tres algoritmos novedosos para el desarrollo de un LMFS en el lado del usuario. El primero de ellos busca mejorar la adaptabilidad del LMFS manteniendo una buena precisión y capacidad de autonomía. Denominado ETA, consiste del uso de una estructura ANFIS que es entrenada por un algoritmo genético multi objetivo (MOGA). Como resultado de este híbrido, obtenemos un algoritmo con excelentes capacidades de generalización y fácil de adaptar para el entrenamiento y evaluación de nuevas estructuras adaptativas basadas en ANFIS. El segundo de los algoritmos desarrollados aborda la autonomía del LMFS para así poder generar modelos de múltiples cargas. Al igual que en la anterior propuesta usamos un ANFIS y un MOGA, pero esta vez el MOGA en vez de entrenar el ANFIS, se utiliza para encontrar la configuración cuasi-óptima del ANFIS. Encontrar la configuración apropiada de un ANFIS es muy importante para obtener un buen funcionamiento del LMFS en lo que a precisión y generalización respecta. El LMFS propuesto, además de configurar automáticamente el ANFIS, incluyó diversos algoritmos para procesar los datos puros que casi siempre estuvieron contaminados de datos espurios y gaps de información, operando satisfactoriamente en las condiciones de prueba en un escenario real. El tercero y último de los algoritmos buscó mejorar la precisión manteniendo la autonomía y adaptabilidad, aprovechando para ello la existencia de patrones dominantes de más baja resolución temporal que el consumo objetivo, y que son más fáciles de modelar y pronosticar. La metodología desarrollada se basa en la transformada de Hilbert-Huang para detectar y seleccionar tales patrones dominantes. Además, esta metodología define el uso de modelos parciales de los patrones dominantes seleccionados, para mejorar la precisión del LMFS y mitigar el problema de aleatoriedad que afecta a los consumos en el lado del usuario. Adicionalmente, se incorporó el algoritmo de auto configuración que se presentó en la propuesta anterior para hallar la configuración cuasi-óptima de los modelos parciales. Este punto fue crucial puesto que a mejor configuración de los modelos parciales mayor es la mejora en precisión del pronóstico final. Finalmente y para cerrar este trabajo de tesis, se realizó una prospección de las tendencias en cuanto al uso de iEMS y se esbozaron varias propuestas de algoritmos híbridos, cuyo estudio y comprobación se plantea en futuros estudios.

Neseniai buvo sukurti nauji radikalinės polimerizacijos metodai, kurie priskiriami gyvybingajai (valdomai) polimerizacijai (GRP). Makromonomerų (MM) gyvybingoji radikalinė polimerizacija yra efektyvus būdas gauti šepetinius (cilindrinius) polimerus). Šepetiniai polimerai – tai makromolekulės, kuriose prie pagrindinės polimerinės grandinės prijungta daug šoninių mažesnės molekulinės masės polimerinių (oligomerinių) grandinių. Dėl tarp šoninių grandinių esančių erdvinės stūmos jėgų tokios makromolekulės įgauna neįprastų savybių, pvz., standumą, cilindrinę formą, didelį segmentų tankį.

The traditional power grid paradigm of centralized and actively controlled power generation facilities serving distributed and passively controlled electrical loads is challenged by the requirements for decarbonization, enhanced reliability and transportation electrification. The power grid will undergo technical, economic and regulatory changes and motivates new control and automation technologies and incentivized Demand Side Management (DSM) to accommodate the intermittent and distributed nature of renewable energy. The first phase of this thesis is an extensive review of existing renewable energy integration study methodologies and their limitations. On the other hand, a newly developed holistic enterprise control assessment method manages the diversity of control solutions and many competing objectives, is case independent, addresses both physical nature as well as enterprise control processes, and is validated by a set of numerical simulations. Another major omission in the majority of integration studies is the demand side resources. Demand Side Management with its ability to allow customers to adjust electricity consumption in response to market signals has often been recognized as an efficient way to mitigate the variable effects of renewable energy as well as to increase system efficiency and reduce system costs. Dispite the recongnized importance of DSM, the academic & industrial literature have taken divergent approaches to DSM implementation. While the popular approach among academia adopts a social welfare maximization formulation, the industrial practice compensates customers according to their load reduction from a predefined electricity consumption baseline that would have occurred without DSM. This thesis then rigorously compares the two different DSM approaches in a dayahead electricity wholesale market analytically and numerically using the same system configuration and mathematical formalism. The comparison of the two models showed that a proper reconciliation of the two models might make them mitigate the stochastic netload in fundamentally the same way given an industrial baseline equal to the dispatchable demand forecast in the social welfare model, which is rarely met in practice. While the social welfare model uses a stochastic net load composed of two terms, the industrial DSM model uses a stochastic net load composed of three terms including the additional baseline term. DSM participants have the incentives to manipulate the baseline in order to receive greater financial compensation, taking advantage of greater awareness of their facilities than the regulatory agencies charged with estimating the baseline. In a day-ahead wholesale market, the artificially inflated baseline forecast used in the industrial formalism is shown to result in higher and costlier dispatchable resources scheduling and unachievable social welfare compared to the academic method. This thesis proceeds to compare the two DSM approaches and quantifies the technical impact of industrial baseline errors in subsequent layers of control using an enterprise control methodology. The baseline inflation errors in a day-ahead market have to be corrected in the downstream enterprise control activities at faster time scales, increasing the control efforts and reserve requirements in the real-time market dispatch and regulation service respectively. The adoption of enterprise control simulator added with a dispatchable demand module enables the simultaneous study of day-ahead and real-time market, regulation service and power flow analysis. The day-ahead wholesale market adopts a unit commitment problem and the real-time wholesale market adopts an economic dispatch (ED) problem on the timescale of minutes. While baseline error is absent in the social welfare model, the industrial model is simulated with different baseline levels, assuming the baseline inflation has the same effects in the day-ahead and real-time market. The resulting implications of baseline errors on power grid imbalances and regulating reserve requirements are tracked. It is concluded that with the same regulating service, the introduction of baseline error leads to additional system imbalance compared to the social welfare model results, and the imbalance amplifies itself as the baseline error increases. As a result, more regulating reserves are required to achieve the same satisfactory system performance with higher baseline error. In summary, the industrial DSM baseline inflation brings about higher and costlier dispatch in day-ahead wholesale market and higher reserve requirements in subsequent control layers, namely the real-time market regulating service.

The main purpose of this study was to carry out a detailed study of the flowfields between the leaflets of widely used bileaflet heart valves. In conventionalresearch, the sewing ring of the valve acts as an obstacle for measurement. In addition, the small space in between the leaflets limits the amount of detailed measurement, which can be done. Therefore, in this study two enlarged semicircular plates were used to mimic the actual fully-opened leaflets during peak systole and the flow field was measured according to dynamic similarity. Flow visualization technique and Laser Doppler anemometer (LDA) were used toobtain qualitative and quantitative data, respectively of the various turbulence characteristics of the flow between the plates and downstream near the wake. The spacings and angles of the plates were changed to study their interactions. Shear stresses in the flow and along the walls of the plates were also measured to evaluate the damage inflicted on red blood cells and platelets. According to experimental result of the visualization flow fields, the deflection of the central flow field is more obvious as the angle of bileaflets becomes larger because of the Coanda effect. However, the direction of deflection is not specific and is especially obvious when the plates' angle is 12° and the interval is 7.5 mm. As the interval increases, the Coanda effect tends to decrease. The LDA measurements show that the maximum shear stress is smallest when the plate are fully open and the angle between a single leaflet and streamwise flow is 0°~6°, thus lowering the possibility of thrombosis.

The behaviour of vortices induced by a single square cylinder and a pair of side-by-side square cylinders in an oscillating flow is investigated. The flow patterns in the vicinity of square cylinders are visualized using the experimental approach and the numerical model. Meanwhile, force coefficients exerted on square cylinders are determined numerically. The results reveal that the flow patterns for an oscillating flow past a single cylinder can be divided into three modes: (i) a pair of attached vortices, (ii) a pair of separation and symmetric vortices, and (iii) vortex shedding as Keulegan-Carpenter number increases. Reynolds number does not affect the flow field apparently. In addition, the in-line force coefficient decreases exponentially as Keulegan-Carpenter number increases. For an oscillating flow past a pair of side-by-side cylinder, the gap ratio plays a vital role in the flow variation. The jet-like structure is found when fluids flow through the gap. In addition, the gap causes the earlier appearance of asymmetric vortex shedding. The in-line force and lift force coefficients of two square cylinders are determined numerically and analyzed using the spectrum analysis and phase diagrams. In terms of those results, the transition of the flow field from the order state to the chaotic state is demonstrated.

Abstract The objective of this research is to investigate the flow interference and heat transfer phenomenon of a pair of identical circular cylinder, arranged side-by side in cross flow with various pitch ratios at Reynolds number of 1000. The analysis was performed by using the FLUENT software, the flow and temperature fields, jet deflection, flow interference, and the local and the average Nusselt numbers were studied in this research. It is observed that as the pitch ratios between 2.0 and 1.5, the jet emerging between cylinders deflects and forms one wide and one narrow wakes behind the cylinders. The gap flow velocity increases as the pitch ratio decreases and consequently increases the average Nusselt number of the cylinders. As the pitch ratio less than 1.5, the jet deflection is more severe and the gap flow velocity starts to decrease slowly. This results to reduce the average Nusselt number of the cylinders. Due to the reduction of the narrow wake width, the average Nusselt number of the cylinder with narrow wake shows an uprising tendency for the pitch ration less than 1.2.

From my experience and take it extended to other adult-son, the purpose of this research is trying to get realized that how they explain their affective interactions between them and their fathers. We invite three adult-sons who is at the period of earlier adult stage. We get the analyzed-information from half-structured interview of qualitative research. At last, we analyze the information by the way of narrative analyzed. Total invite 3 men to participate this research, age from 25~30. Collage graduated at least. "From behind to side by side" is a symbolic of the relationship in father and son. We find that not only time increasing can make them getting closer but also the grow up of their mind. They try to learn more about effective expression, and think maturely to each other. In adult sons’ mind, they take more empathy and positive thinking to understand the past of their fathers. It makes them realized more about their fathers, and lead their fathers to upgrowth themselves. The intimacy and right between father and son will be turned back because the sons’ interpretation of their fathers. We find that the research participators care more about getting "identification" from their fathers rather than getting warm. It shows that be identified is the most important thing in the affective interaction and sons do care about that. Comparing with before, fathers in now days show more inter-affection by saying and show how they love their family and their sons, and they will present it with humorous to avoid some unknown embarrassment in the family interaction. At last, we will provide our suggestion in practice and research ways. Key words: affective interaction, empathy, masculinity, exchange of intimacy and right

This dissertation consists of two parts. The first one is to study the flame stabilization and lift-off over a Tsuji burner using a four-step chemical kinetics in the combustion model developed by Chen and Weng (1990A). The second part is to investigate the flame interference/interaction phenomena between two cylindrical burners in a side-by-side arrangement. A multi-block grid system is introduced to implement the model, however, one-step overall chemical kinetics is used in this part. For the single burner case, the parameters of interest are the inflow air velocity (Uin) and fuel-ejection area (S) of the cylindrical burner. Comparing the blow-off curve of Tsuji (1982) with that of Chen and Weng (1990) reveals that this simulation yields a much better prediction than that in the latter reference. Also, the present predictions have an excellent agreement with the measured data of Dreier et al. (1986). As Uin increases, the envelope diffusion flame, wake flame, lift-off flame, and wake flame appear in order before complete extinction. The formal wake flame is transformed from envelope one and the latter is from the lift-off flame. The existence of a lift-off flame is verified by a corresponding experimental observation (Chang, 2002). The maximal lift-off height is 1.7D when Uin is 1.05 m/sec, and this height is retained up to Uin = 1.09 m/sec. Then, the height declines gradually as the inflow velocity increases, whose process can be regarded as flashback. No recirculation flow exists behind the cylindrical burner for these lift-off flames. A transition from lift-off to wake flame occurs between 1.13 to 1.15 m/sec. The wake flame reappears at Uin = 1.16 m/sec. Finally, the flame is extinguished completely when Uin > 2.12 m/sec. An explanation for flame’s lifting off and dropping back is given. In the second part, a preliminary study for a cold flow over the twin cylinders is given first. Comparing the drag coefficient curve of Hori (1959) with the predicted one by the present study reveals that this simulation yields a reliable prediction. After that, a parametric study is given as well. For flame interference between dual cylindrical burners, comparison of the flame transition curve between Wang (1998) and Chen’s (2003) experiments and the present simulation indicates that this simulation can correctly predict the trend for the variation of flame transition velocity with intercylinder spacing. For the parametric studies, the interested ones are the intercylinder spacing (L) and inflow velocity (Uin), respectively. For flame interference, in general, the wider the intercylinder spacing, the lower the flame transition velocity, which transforms the envelope flame into the wake flame. However, the combustion efficiency increases with L. The twin envelope diffusion flames merge into a larger envelope diffusion flame completely as L is equal to or less than 1.5D. There is only one vortex behind each burner as L = 1.5D or 2D. However, no vortex is found behind in each burner as L = 1.2D. As L is equal to or greater than 3.5D, there is no interference at all between the two flames. The controlling mechanism of mutual interaction for twin counterflow diffusion flames is the oxygen deficiency between the dual flames. In the case of varying Uin under fixed L = 3D, as Uin increases to 0.79 m/sec, the dual envelope diffusion flames transform into dual wake flames. When Uin further increases to 1.96 m/sec, the dual wake flames extinguish. Raising the inflow velocity can enhance the mutual interaction between dual envelope flames. The larger the inflow velocity, the lower the flame temperature due to the flame stretch effect. Besides, there exist three vortices behind each cylinder as flames are near extinction, and this is quite different from another case. For fixed intercylinder spacing, the dual flames have a tendency to attract each other normally due to the mutual interaction between flames. However, as the inflow velocity increases to near extinction limit, the dual flames repel each other.

Abstract The present paper investigates flow characteristics of influence of arrangement position on flow downstream of bluff bodies arranged side by side.The bluff bodies adopted include two-dimensional flat plates,square cylinders,and circular cylinders. The two-body arrangements are comprised arrangement position of flat plate and square cylinder, flat plate and circular cylinder.Two sets of models are adopted,these being bluff bodies with the same cross-setional dimension but with different vortex shedding frequencies,and bluff bodies with different cross-setional dimension but with the same vortex shedding frequency. The results demonstrate that the characteristics of flow downstream are significantly related to arrangement position and cross-settional geometry of the bluff body.the gap flow tends to deflect toward the narrow-wake side downstream of the two-body arrangement side by side.The biasing characteristic of the gap flow is relatively unstable as the widths of the wake downstream of each bluff body are nearly the same.

The experiments were conducted in the wind tunnel to measure the dispersion characteristics of the two side by side sources located before fence,Effects of the location of fence, gap of two sources, and source hight on the wind flow and dispersion characteristics were investigated. Experimental results show that:(1)The wind accelerated as it past the fence, then the wind speed decreased, due to blockage effect of the fence. Furthermore,the reverse flow appeared behind the fence.(2)When the gap of two sources was 18 times source diameter, two concentration plumes interacted and merged around at downstream distance of three times of source heights.

The experimental investigation is to study, based on wavelet analysis, the locked-on characteristics of wakes behind two side-by-side circular cylinders with various excitation frequencies in the low-speed water channel. Quantitative velocity measurements and qualitative dye flow visualization were performed by way of the LDA system and the laser sheet technique, respectively. In this study, two side-by-side circular cylinders has different diameters (d/D=1/2). The net gap ratio between two cylinders is 3D/4, and the Reynolds number based on the large cylinder diameter is 1160. One of the cylinders is perturbed in front of an oscillatory rotation about it’s center with a constant amplitude of tangential velocity. It is found that:(1) When the large cylinder is perturbed at various excitation frequencies, the locked-on band of the narrow and the wide wakes behind each cylinder tend to shift towards the natural shedding frequency of the individual cylinder. When the excited at proper frequency, both the wide and the narrow wakes behind two circular cylinders are locked-on simultaneously but at the distinct frequency. This is called double lock-on phenomena. (2) When the small cylinder is perturbed at various excitation frequencies, the locked-on bandwidth of the wide wakes is located with fe*=0.7~0.9. The locked-on bandwidth of the narrow wakes is located at fe*=2.2~3.2. And the double locked-on of both wakes happens to be within fe*=0.9~1.2. (3) By wavelet transformation and analysis, it is shown that the characteristics frequency of the gap flow is dominated by the frequency of narrow wake when unperturbed. However, the responding frequency in gap flow is dominated by the characteristics frequency of the wide wake when the wide wake is excited near it’s nature shedding frequency. This reveals the direct evidences of flow coupling between the wide and narrow wakes.

This study experimentally investigated the fundamental characteristics of wake structures behind two circular cylinders aligned side by side with different net gap ratios, ranging from infinite to 0.25. The Reynolds number, according to cylinder diameter and free stream velocity, varied from 324 to 1080 in a uniform flow by using Particle image velocimetry (PIV), fiber laser Doppler velocimetry (FLDV), and two flow visualization techniques were used to explore this flow field. In the processes of experiment, PIV system is the major measurement equipment used to measure the whole velocity filed. And the present results show the drawings of velocity field with distinct net gap ratios and Reynolds numbers to compare with the flow-visualization photos, and to compute the length of the formation region and the bias angle of the gap flow according to those velocity data. At the last, this study synchronized to measure the cyclical processes of vortex evolution behind two circular cylinders by using PIV and FLDV systems at the same time. And then to analyze all transient velocity fields which are measured by PIV system into each phase- averaged velocity field in a cycle of the wake flow field by applying the modified phase-average method, and confer the characteristics which are changed according to time of wake flow field of circular cylinders.
