After the domination of behaviourism in Anglo-American psychology during the
middle of the century, the impression has been left, reflected in the many texts on
research design, that the experimental method is the central tool of psychological
research. In fact, a glance through journals will illuminate a wide array of datagathering
instruments in use outside the experimental laboratory and beyond the
A wide range of issues related to analysis of gas turbines and their engineering applications are considered in the book. Analytical and experimental methods are employed to identify failures and quantify operating conditions and efficiency of gas turbines. Gas turbine engine defect diagnostic and condition monitoring systems, operating conditions of open gas turbines, reduction of jet mixing noise, recovery of exhaust heat from gas turbines, appropriate materials and coatings, ultra micro gas turbines and applications of gas turbines are discussed.
This book is intended to present for the first time experimental methods to measure equilibria states of pure and mixed gases being adsorbed on the surface of solid materials. It has been written for engineers and scientists from industry and academia who are interested in adsorption based gas separation processes and/or in using gas adsorption for characterization of the porosity of solid materials

This chapter presents the uses of experimentation and the various types of experimental designs. It also discusses the advantages and disadvantages of the experimental method. After studying this chapter you will be able to understand: Uses for experimentation, advantages and disadvantages of the experimental method, seven steps of a well-planned experiment, internal and external validity with experimental research designs, three types of experimental designs and the variations of each.
This strategic lab guide explores the current methodological variety of molecular biology and genomics in a simple manner, addressing the assets and drawbacks as well as critical points. It also provides short and precise summaries of routine procedures as well as listings of the advantages and disadvantages of alternative methods.This lab book illustrates ways out of experimental dead ends and teaches a feeling for doing the right experiment at the right time.
The 21st century is said to be a photon-century. People meet contemporary optics
(holography, as well) applications everywhere. It would be appropriate to increase the
common education level in this field for people to be able to understand new surrounding
technologies, entering our everyday lives. Optics serves as an important part of many
scientific experimental methods. This way, such information could be useful also for
researchers without a professional optical education.
State-of-the-art statistical machine translation (MT) systems have made signiﬁcant progress towards producing user-acceptable translation output. However, there is still no efﬁcient way for MT systems to inform users which words are likely translated correctly and how conﬁdent it is about the whole sentence. We propose a novel framework to predict wordlevel and sentence-level MT errors with a large number of novel features. Experimental results show that the MT error prediction accuracy is increased from 69.1 to 72.2 in F-score. ...
Lecture Quantiative methods for bussiness - Chapter 2 introduction to probability. This chapter presents the following content: Experiments and the sample space; assigning probabilities to experimental outcomes; events and their probabilities; some basic relationships of probability; Bayes’ theorem.
The main contents of this chapter include all of the following: Simulation modeling, random variables and pseudo-random numbers, time increments, experimental design, simulation applications, computer implementation, verification and validation, advantages and disadvantages of using simulation.
As described in this paper, we propose a new automatic evaluation method for machine translation using noun-phrase chunking. Our method correctly determines the matching words between two sentences using corresponding noun phrases. Moreover, our method determines the similarity between two sentences in terms of the noun-phrase order of appearance. Evaluation experiments were conducted to calculate the correlation among human judgments, along with the scores produced using automatic evaluation methods for MT outputs obtained from the 12 machine translation systems in NTCIR7.
This paper raises concerns that natural language front ends for computer systems can limit a researcher's scope of thinking, yield inappropriately complex systems, and exaggerate public fear of computers. Alternative modes of computer use are suggested and the role of psychologically oriented controlled experimentation is emphasized. Research methods and recent experimental results are briefly reviewed.
In this paper, we present a feature-based method to align documents with similar content across two sets of bilingual comparable corpora from daily news texts. We evaluate the contribution of each individual feature and investigate the incorporation of these diverse statistical and heuristic features for the task of bilingual document alignment. Experimental results on the English-Chinese and EnglishMalay comparable news corpora show that our proposed Discrete Fourier Transformbased term frequency distribution feature is very effective. ...
This study uses what Cresswell (2003) refers to as a ‘mixed methods approach’, one that combines
quantitative and qualitative data collection and a ‘sequential explanatory strategy’ in which the
collection and analysis of the quantitative data is followed by the collection and analysis of the
qualitative data (p 215).

As currently taught, the introductory course in analytical chemistry emphasizes
quantitative (and sometimes qualitative) methods of analysis coupled with a heavy
dose of equilibrium chemistry. Analytical chemistry, however, is more than equilib-
rium chemistry and a collection of analytical methods; it is an approach to solving
chemical problems. Although discussing different methods is important, that dis-
cussion should not come at the expense of other equally important topics.
This book focuses on the basic electrochemical applications of DNA in various areas, from basic principles to the most recent discoveries. The book comprises theoretical and experimental analysis of various properties of nucleic acids, research methods, and some promising applications.
This book compiles recent studies on interferometry and its applications in science and
technology. It is intended as an up-to-date reference of theoretical and experimental
aspects of interferometry and their applications.
The book is divided in two sections. The first one is an overview of different
interferometry techniques and their general applications. Chapter 1 is concentrated
on the classical field interferometry. This chapter describes and explains the
structures of different type of fiber interferometers, and the standard methods for
The second section of the book involves the regional biogeography of individual taxa.
This section begins with a chapter by Alberto Taylor and his colleagues on the
biogeography of cycads in Central America. Their natural history and experimental
ecological methods integrate the evolutionary context of the cycad lineage with
contemporary autecology, and they elucidate biogeographic patterns and conservation
priorities, the latter of which are under-appreciated but pressingly important in
Measurement is a multidisciplinary experimental science. Measurement systems synergistically blend science, engineering and statistical methods to provide fundamental data for research, design and development, control of processes and operations, and facilitate safe and economic performance of systems. In recent years, measuring techniques have expanded rapidly and gained maturity, through extensive research activities and hardware advancements.
