Time series models for business and economic forecasting / Philip Hans Franses, Dick van Dijk and Anne Opschoor.
No full texteconomic&political bookfair2015Includes bibliographical references and index.xii, 300 pages :"With a new author team contributing decades of practical experience, this fully updated and thoroughly classroom-tested second edition textbook prepares students and practitioners to create effective forecasting models and master the techniques of time series analysis. Taking a practical and example-driven approach, this textbook summarises the most critical decisions, techniques and steps involved in creating forecasting models for business and economics. Students are led through the process with an entirely new set of carefully developed theoretical and practical exercises. Chapters examine the key features of economic time series, univariate time series analysis, trends, seasonality, aberrant observations, conditional heteroskedasticity and ARCH models, non-linearity and multivariate time series, making this a complete practical guide. A companion website with downloadable datasets, exercises and lecture slides rounds out the full learning package"-- Provided by publisher."The econometric analysis of economic and business time series is a major field of research and application. The last few decades have witnessed an increasing interest in both theoretical and empirical developments in constructing time series models and in their important application in forecasting. This book aims at reviewing several important developments within the context of forecasting business and economic time series"-- Provided by publisher
Natural products in medicinal chemistry / edited by Stephen Hanessian.
No full textpharmacy bookfair2016Includes bibliographical references and index.xxi, 630 pages :The inspiration provided by biologically active natural
products to conceive of hybrids, congeners, analogs and
unnatural variants is discussed by experts in the field in 16
highly informative chapters.
Using well-documented studies over the past decade, this
timely monograph demonstrates the current importance
and future potential of natural products as starting points for
the development of new drugs with improved properties
over their progenitors.
The examples are chosen so as to represent a wide range
of natural products with therapeutic relevance among
others, as anticancer agents, antimicrobials, antifungals,
antisense nucleosides, antidiabetics, and analgesic
MATLAB optimization techniques / César Pérez López.
No full textDescription based on print version record.xi, 277 pages :MATLAB is a high-level language and environment for numerical computation, visualization, and programming. Using MATLAB, you can analyze data, develop algorithms, and create models and applications. The language, tools, and built-in math functions enable you to explore multiple approaches and reach a solution faster than with spreadsheets or traditional programming languages, such as C/C++ or Java. MATLAB Optimization Techniques introduces you to the MATLAB language with practical hands-on instructions and results, allowing you to quickly achieve your goals. It begins by introducing the MATLAB environment and the structure of MATLAB programming before moving on to the mathematics of optimization. The central part of the book is dedicated to MATLAB?s Optimization Toolbox, which implements state-of-the-art algorithms for solving multiobjective problems, non-linear minimization with boundary conditions and restrictions, minimax optimization, semi-infinitely constrained minimization and linear and quadratic programming. A wide range of exercises and examples are included, illustrating the most widely used optimization methods
Effect of changes in sintering parameters on monolithic translucent zirconia
No full textObjectives. Aim of this study was to evaluate the effect of different sintering parameters on color reproduction, translucency and biaxial flexural strength of monolithic zirconia. Methods. Translucent zirconia discs having 15 mm diameter, 1 mm thickness, and shade A3 were milled and divided according to the sintering temperatures (1460C) into three groups (n = 30). Each group was later divided into three subgroups (n = 10) according to the sintering holding time (1, 2, and 4 h). Easyshade spectrophotometer (Vita, Bad Säckingen, Germany) was used to obtain the E between the specimens and the shade A3. Mean E values below 3.0 were considered “clinically imperceptible”, E values between 3.0 and 5.0 were considered “clinically acceptable” and E values above 5.0 were considered “clinically unacceptable”. Contrast ratio (CR) was obtained after comparing the reflectance of light through the specimens over black and white background. Biaxial flexural strength was tested using the piston-on-three balls technique in a universal testing machine. Results. Mean E results ranged from 4.4 to 2.2. Statistically significant decrease in the Delta E was observed as the sintering time and temperature increased. CR decreased from 0.75 to 0.68 as the sintering time and temperature increased. No significant change in the biaxial flexural strength was observed.Significance. Sintering zirconia using long cycles and high temperatures will result in reduc- tion of E and CR. Biaxial flexural strength is not affected by changes in the evaluated sintering parameters

Opinion Mining and Sentimental Analysis Approaches : A Survey
No full textThe automatic extraction of information from unstructured sources has opened up new ways for querying, organizing, and analyzing data by building a clean semantics of structured databases from a huge number of unstructured data and the society became more data oriented with easy online access to both structured and unstructured data. New applications of structured extraction came around such as the paper topic opinion mining, which is a type of natural language processing for tracking the mood of the public about a particular topic. Opinion mining, which is also called sentiment analysis, involves building a system to collect and examine opinions about the product or topic made in blog posts, comments, reviews or tweets. Automated opinion mining often uses machine learning, which is a component of artificial intelligence (AI)
Speed control of BLDC motor by using PID control and self-tuning fuzzy PID controller
No full textThis paper presents three different robust controller techniques for high performance brushless DC (BLDC) motor. The purpose is to test the ability of each control technique to force the rotor to follow a preselected speed/position track. This objective should be achieved regardless the parameter variations, and external disturbances. The first technique is conventional PID controller. The second controller technique use genetic algorithm to adjust the PID controller parameters based on three different cost functions. Finally a self-tuning fuzzy PID controller is developed and tested. These controllers are tested for both speed regulation and speed tracking. Results shows that the proposed self-tuning fuzzy PID controller has better performance
Body sculpting with silicone implants / [edited by] Nikolas V. Chugay, Paul N. Chugay, Melvin A. Shiffman.
No full textxiv, 258 p. :This book covers all aspects of body contouring with silicone implants with the exception of breast augmentation. After a discussion of the available silicone implants and anesthetic management, the various techniques that may be used in body sculpting are carefully described in a series of chapters focusing on augmentation of the biceps, triceps, pectorals, buttocks, hip/thigh, calf, and quadriceps. Potential complications are identified for each of the procedures and clear guidance is provided on how to avoid them. The book will enable the surgeon to gain a sound understanding of the different body sculpting techniques and when they are applicable. It is intended both for students/beginners and for experienced cosmetic plastic surgeons alike
