Abstract:

Single layer feed forward neural networks with hidden nodes of adaptive wavelet functions (wavenets) have been successfully demonstrated to have potential in many applications. Yet applications in the process control area have not been investigated. In this paper an application to a self-tuning design method for an unknown nonlinear system is presented. Different types of frame wavelet functions are integrated for their simplicity, availability, and capability of constructing adaptive controllers. Infinite impulse response (IIR) recurrent structures are combined in cascade to the network to

Abstract:

Cavity filters are a necessary component in base stations used for telecommunication. Without these filters it would not be possible for base stations to send and receive signals at the same time. Today these cavity filters require fine tuning by humans before they can be deployed. This thesis have designed and implemented a neural network that can tune cavity filters. Different types of design parameters have been evaluated, such as neural network architecture, data presentation and data preprocessing. While the results was not comparable to human fine tuning, it was shown that there was a re

La classificazione automatizzata di documenti digitalizzati in categorie predefinite ha sollevato un grande interesse fin dagli anni 2000. Questo è dovuto al sensibile aumento di documenti in formato digitale ed alla crescente necessità di dar loro un’organizzazione gerarchica. Inoltre, principalmente a causa della grande mole di documenti da categorizzare, negli ultimi anni si richiede che tale compito venga gestito in modo automatizzato. In ambito aziendale, queste problematiche vengono spesso affrontate mediante l’utilizzo di soluzioni “black box” proprietarie. Tali soluzioni si rivelano

This thesis focuses on modelling of passive hydraulic automotive dampers for use in computationally-fast vehicle-dynamic simulation.

Initially the extension includes just additional input kinematics to account for inertial effects, with an imposed temperature profile. Subsequently a heat g

The concept takes advantage of the principles employed in vibratory gyro sensors and the ductile attributes of GalFeNOL to target high sensitivity and shock tolerance. The sensor is designed as a tuning fork structure. A GalFeNOL patch attached to the y-z surface of the drive prong causes both prongs to bending the x-z plane (about the y axis) and a patch attached to the x-z surface of the sensing prong detects Coriolis-force induced bending in the y-z plane (about the x axis).

Component values of integrated filters vary considerably due to· manufacturing tolerances and environmental changes. Thus it is of major importance that the components of an integrated filter be electronically tunable. The method explored in this thesis is the transconductance-C-method. A method of realizing higher-order filters is to use a cascade structure of second-order filters. In this context, a method of tuning second-order filters becomes important The research objective of this thesis is to determine if the Neural Network methodology can be used to facilitate the filter tuning process

Abstract:

Routing within a telecommunication network defines how the traffic flow is mapped on the network topology. The increasing commercial importance of the Internet together with a rising number of real-time applications make of the routing mechanisms as essential feature in the control of the network performance. The routing mechanisms involved allow to assign the network capacities, more or less efficiently, to the demands or requests of traffic. The routing choice has a direct impact on the existence and location of congestion within the network. A high level of congestion may decrease the grade

Deep learning has been rapidly growing in recent years obtaining excellent results for many computer vision applications, such as image classification and object detection. One aspect for the increased popularity of deep learning is that it mitigates the need for hand-crafted features. This thesis work investigates deep learning as a methodology to solve the problem of autonomous collision avoidance for a small robotic car. To accomplish this, transfer learning is used with the VGG16 deep network pre-trained on ImageNet dataset. A dataset has been collected and then used to fine-tune and valid

Abstract:

Huvudsyftet med vår studie är att undersöka och analysera hur personal i hemtjänsten upplever sin arbetssituation samt vad relationerna till arbetskamrater respektive brukare kan ha för betydelse för denna upplevelse. Vi har därför valt en kvalitativ ansats med semistrukturerade intervjuer, som bygger på intervjupersonernas egna upplevelser av sin verklighet. Vårt övergripande perspektiv på studien är socialpedagogiken. Den teoretiska ramen består sociala nätverk, samt begreppen gemenskap och tunna nätverksband. Datamaterialet som insamlats har kodats, kategoriserats, tematiserats och analyser

Abstract:

This work deals with obtaining pedestrian information, which are captured by static, external cameras located in public, outdoor or indoor spaces. The aim is to obtain as much information as possible. Information such as gender, age and type of clothing, accessories, fashion style, or overall personality are obtained using using convolutional neural networks. One part of the work consists of creating a new dataset that captures pedestrians and includes information about the person's sex, age, and fashion style. Another part of the thesis is the design and implementation of convolutional neural

The associations between input and output of fuzzy set will be clearly described based on the adapiive capability of neural network. 　　Fuzzy theory has been applied into a wide variety of engineering and business areas. Fuzzifier, rule base and defuzzifier are three main cores in fuzzy mechanism Rule base could be built generally by designer's expertise based on the characteristics of the system approached. It consists of a set of fuzzy IF-THEN rules. I

碩士<br>南台科技大學<br>工業管理研究所<br>94<br>In the semiconductor manufacturing, Exponentially Weighted Moving Average (EWMA) controller has been shown to be an effective feedback control system. The performance of the EWMA controller depends heavily on the weight parameter (also called “discount factor”) of the system. According to the realization of the literature, using adaptive discount factors provides EWMA controllers that are superior to those using fixed discount factors. The reason is that shift or drift often exists in the semiconductor manufacturing, resulting in a process with unexpected bi

Regarding car metal as an antenna, so don’t need additional antenna structure. By using L-matching network to match the antenna, the inductance and capacitance can be switched to different values by diode switches, achieving impedance match at different frequencies. Finally, a matching network consists of 4 inductors, 3 capacitors and 7 diodes were designed and fabricated. The measured results show that the S_11 are all lower than -10

The modern requirements of parameters variations and operation conditions variations become the new challenges for convention PID controls, which have used to be applied to electro-hydraulic servo systems. This paper is concerned with a new architecture of a self-tuning neural-PID control system and its application to control the displacement of an electro hydraulic servo system.
