Abstract:

This project explores the rapidly expanding area of AC direct drive for LED lighting. AC LED driving does not use typical DC-DC converter-based driving but uses semiconductor switches and a linear regulator to activate a number of LEDs proportional to the input voltage at any given time. This allows bulky, expensive magnetics to be eliminated from the system. The goal of this project was to design a scaled-down physical AC LED direct drive system to validate the conclusions of methods for improving efficiency from a previous investigation that found minimizing voltage across the linear regulat

The Marchamalo salt flats, built in the 18th century, are located near Cabo de Palos, Murcia (Spain), in a hot spot area with constant pressures of tourism and urban speculation. The salt flats are currently abandoned, but its landscape and ecological value still subsist. This Thesis aims to develop a low impact lighting Master plan for Marchamalo salt flats in which a comprehensive analysis is relevant for the design project. A holistic analysis method is employed which considers three agents: “Space”, “Humans” and “Light” to which the factor “Flora & Fauna” was added since the original m

Abstract:

Companies have long been interested in gauging the customer’s level of interest in their advertisements. By analyzing the gaze direction of individuals viewing a public advertisement, we can infer their level of engagement. Head pose detection allows us to deduce pertinent information about gaze direction. Using video sensors, machine learning methods, and image processing techniques, information pertaining to the head pose of people viewing advertisements can be automatically collected and mined. We propose a method for the coarse classification of head pose from low-resolution images in cro

Abstract:

Computer vision is a key component of any autonomous system. Real world computer vision applications rely on a proper and accurate detection and classification of objects. A detection algorithm that doesn’t guarantee reasonable detection accuracy is not applicable in real time scenarios where safety is the main objective. Factors that impact detection accuracy are illumination conditions and image resolution. Both contribute to degradation of objects and lead to low classifications and detection accuracy.

Lightning protection is an issue of safety for humans and their properties. Although humans may be protected against a direct lightning strike if they are situated into a modem structure, electrical and electronic appliances, which equip the structure may suffer fatal damages. These damages can be avoided by taken the necessary protective measures. Depending on the low voltage distribution system that connects the structure, the necessary protective measures may vary due to different risks that are associated with each low voltage distribution system.

Abstract:

Lightning is the strongest natural electromagnetic radiation source, emitting electromagnetic energy in the frequency range from ~4 Hz to ~300 MHz or more. The location of lightning is calculated based on the received electromagnetic waves. The received electromagnetic waves, or lightning sferics, propagate from the lightning radiation source to the receiver along the ground path and reflections by the ionosphere named sky waves. Particularly for a long-baseline (>400 km) lightning receiver array, the received electromagnetic waves are usually a mixture of the ground wave and sky waves, which

Challenging conservative notions of the revolution as a bloody and anarchic affair, Chartists constructed histories of 1789 that posed the era as a romantic struggle for freedom and nationhood analogous to their own, and one that was deeply entwined with British history an

碩士<br>國立中山大學<br>公共事務管理研究所<br>100<br>The background and motivation of this study are based on: (1) Energy saving and carbon emission reduction are the rising issues gaining more awareness and efforts worldwide. (2) Taiwan plans to build “low-carbon cities” in order to implement the policy of greenhouse gas reduction. (3) The most direct and practical way to reduce carbon emissions is by saving energy. (4) Everyone has to use illumination sources. (5) “Electro-Magnetic Induction Lamps” is a useful tool to achieve the goal of energy saving and carbon emission reduction. Thus the topic of this stu

Recently, T5 fluorescent lamps have more advantages than other types of fluorescent lamps in energy-saving policy promoted by the government. This thesis compares the results of T8 and T5 fluorescent luminaires for a basement park lot application. The experimental results can provide valuable reference for users in design or maintenance phases. Moreover, this thesis has demonstrated the feasibility of applying the T5 fluorescent luminaires to replace th

In this study, ATP / EMTP simulation software will simulate the lightning discharge striking the system power of Taipower which provides power to users, home users and distribution lines. First, a SPD will not be installed on the power dis

For analyzing the protection scheme after each outage, the TRTS has organized a research team for this purpose. For each lightning outage, the equipments damaged by lightning strikes are not the same, in view of their usage and location within the depot. Design for the engineering work for improvement of lightning protection carried out, after each outage, are thus on a case-by-case basis, which complicates the

If the electricity for lighting facilities in an underground parking lot can be smartly distributed according to the time of day and the number of cars entering or exiting the parking lot, the overall lighting electricity can be effectively reduced. This study aims to reduce the electric energy consumption of lighting facilities used in underground parking lot. To achieve this objective, infrared and ultra

Consequently,damage cases in the low voltage customers due to lightning and switching surges from feeder are frequent. In the thesis, the characteristics of lightning and switching surges of secondary substation and feeders are analyzed, and the surge voltages from feeder to low voltage customers are surveyed and the affectio

abstract: For the death penalty to be justified, it must be reserved for the worst of the worst. In his 2011 study of Connecticut's death penalty system, however, John Donohue found that arbitrariness and discrimination are defining features. Donohue's finding that non-white defendants whose victims were white are six times more likely to receive the death penalty indicates that race is more a predictor of a death sentence than the egregiousness of the crime. An analysis of capital sentencing outcomes in Maricopa County, Arizona reveals that the race of the victim is not related to the likelih

Abstract:

Το θέμα της παρούσας διπλωματικής εργασίας είναι η μελέτη της συμπεριφοράς απαγωγέων υπερτάσεων (SPD), όταν αυτοί αποτελούν μέρος του εσωτερικού συστήματος αντικεραυνικής προστασίας για μια οικιακή εγκατάσταση. Αρχικά γίνεται μια αναφορά στα αίτια δημιουργίας κρουστικών υπερτάσεων στο δίκτυο διανομής, ενώ στη συνέχεια δίνεται έμφαση στις υπερτάσεις που προκαλούνται από άμεσα ή έμμεσα κεραυνικά πλήγματα στο σύστημα. Στα πλαίσια της μελέτης δημιουργήθηκε ένα μοντέλο προσομοίωσης που αναπαριστά ένα δίκτυο χαμηλής τάσης TN-C-S με δύο πανομοιότυπους οικιακούς καταναλωτές, όσον αφορά τη δομή της εσω

Abstract:

Celem prezentowanej pracy doktorskiej jest odtworzenie i analiza kształtowania się prawa sąsiedzkiego w Egipcie ptolemejskim i rzymskim (od podboju przez Aleksandra Wielkiego po podbój arabski) w oparciu o źródła praktyki, jakimi są papirusy w kilku językach – przede wszystkim greckim i demotycznym, ale z odwołaniami także do tych napisanych po koptyjsku i arabsku. Wśród nich możemy wyróżnić petycje, akty sądowe, instrukcje oraz raporty urzędników, kilka zbiorów praw i edykty prefektów, a także różnorodne kontrakty – umowy kupna-sprzedaży, najmu czy podziału własności, w których zazwyczaj jedy
