Book Description
Resumen La tesis estudia el problema del flujo armónico de cargas desde dos puntos de vista. La formulación del problema del flujo armónico de cargas analizando los distintos métodos existentes en la bibliografía y desarrollando una formulación completa del mismo. Y la resolución numérica del sistema no lineal planteado en la formulación. Analizando los distintos métodos numéricos existentes en la bibliografía y sus problemas de convergencia. Y desarrollando un nuevo método numérico, denominado método de h-newton, que ofrece rapidez y seguridad en la convergencia.

The Radiological Accident in Goiânia
Author: International Atomic Energy Agency
Publisher:
ISBN:
Category : Business & Economics
Languages : en
Pages : 174
Book Description
The Government and authorities in Brazil were faced with a tragic accident in Goiânia resulting from the misuse of a strongly radioactive medical teletherapy source not under radiation protection surveillance. The present report is divided into four parts: a chronology of destruction of the source, discovery of the accident and initial response; a description of the human consequences and the dosimetry and treatment of seriously exposed and contaminated persons; an account of the assessment of the environmental contamination and the remedial actions taken; and observations and recommendations. Appendices and annexes give an assessment of the effectiveness of international co-operation in the emergency response, and provide further information on: public communications; radiological survey equipment; guidelines for the discharge of patients; radiological protection; chemical decontamination; and the lessons learned.

The North American Mosaic
Author: Commission for Environmental Cooperation (Montréal, Québec). Secretariat
Publisher:
ISBN:
Category : Agriculture
Languages : en
Pages : 240
Book Description
The North American Mosaic has four overarching features. First, it is, to the extent feasible, based on comparable information on the status and trends of major indicators of the state of the environment in Canada,Mexico, and the United States. Second, the report confirms that these three countries together make up an incredibly complex, dynamic, and interconnected ecosystem in which humans play a dominant and decisive role. Third, the report raises important and sometimes disquieting questions concerning the sustainability of some current trends. Finally, the report is a reminder that our economic, social, and physical well-being are utterly dependent on the life-sustaining services provided by nature. This report emphasizes the importance of developing mutually compatible economic, social, and environmental goals and policies across the three-country region.

Power Quality Issues
Author: Suresh Mikkili
Publisher: CRC Press
ISBN: 1498729630
Category : Technology & Engineering
Languages : en
Pages : 160
Book Description
Power Quality Issues: Current Harmonics provides solutions for the mitigation of power quality problems related to harmonics. Focusing on active power filters (APFs) due to their excellent harmonic and reactive power compensation in two-wire (single phase), three-wire (three-phase without neutral), and four-wire (three-phase with neutral) AC power networks with nonlinear loads, the text: Introduces the APF technology, describing various APF configurations and offering guidelines for the selection of APFs for specific application considerations Compares shunt active filter (SHAF) control strategies for extracting three-phase reference currents, evaluating their performance under a number of source voltage conditions using a proportional-integral (PI) controller Presents PI controller-based SHAF instantaneous active and reactive power (p-q) and instantaneous active and reactive current (Id-Iq) control strategies, supplying detailed MATLAB®/Simulink simulation results Proposes SHAF control strategies using type 1 and type 2 fuzzy logic controllers (FLCs) with different fuzzy membership functions (MFs), analyzing their harmonic mitigation and DC link voltage regulation Verifies the proposed type 2 FLC-based SHAF control strategies with trapezoidal, triangular, and Gaussian fuzzy MFs using RT-LAB, a real-time digital simulation software from OPAL-RT Technologies Power Quality Issues: Current Harmonics is a useful resource for those tackling electrical power quality challenges. The compensation techniques described in this book alleviate harmonic issues that can distort voltage waveforms, fry a building’s wiring, trigger nuisance tripping, overheat transformer units, and cause random end-user equipment failure.

VOLUNTARY GUIDELINES ON NATIONAL FOREST MONITORING
Author: Food and Agriculture Organization of the United Nations
Publisher: Food & Agriculture Org.
ISBN: 9251096198
Category : Technology & Engineering
Languages : en
Pages : 76
Book Description
National information needs on forests have grown considerably in recent years, evolving from forest area and growing stock information to key aspects of sustainable forest management, such as the role of forests in the conservation of biodiversity and the provision of other ecosystem services. More recently, information on changes in carbon stocks, socio-economic aspects including the contribution to livelihoods and poverty reduction, governance and broader land use issues has become critical for national planning.

Oral Infections and General Health
Author: Anne Marie Lynge Pedersen
Publisher: Springer
ISBN: 3319250914
Category : Medical
Languages : en
Pages : 150
Book Description
This book provides a wide-ranging update on the associations between oral infections and general health. Detailed consideration is given to the underlying mechanisms or pathways linking oral infections to general health, including metastatic spread of infection from the oral cavity as a result of transient bacteremia, metastatic injury from the effects of circulating oral microbial toxins, and metastatic inflammation caused by immunological dysfunction induced by oral microorganisms. The book also reviews the complex structure and development of oral biofilms in health and disease, and the molecular tools that are currently available for their analysis. The advantages and limitations of such techniques, as well as their impact on the future of diagnostics, prevention and patient management, are discussed.
