Experimental study on the spatial coherence and polarization of random optical fields

All optical fields are inherently of statistical nature undergoing random fluctuations. The underlying theory of fluctuating optical fields is known as coherence theory and partial polarization. This thesis describes the experimental study on the coherence and polarization measurements for statistical optical fields. Particular emphasis is placed on the full field visualization for coherence function and coherence matrix, and its application to the study of changes in random optical fields on propagation. The thesis consists of 9 chapters including Chapter 1 devoted to introduction. Chapter 2 proposes a novel optical geometry for the full-field coherence visualization to study the coherence diffraction. The non-diffracting solutions for the coherence function and the coherence interference phenomena have been presented in Chapter 3 and Chapter 4, respectively. As the application, Chapter 5 presents the experimental demonstration of the coherence holography to synthesize the arbitrary spatial coherence function. To take the vector nature, Chapter 6 and Chapter 7 develop our optical geometry for the full-field visualization of coherence polarization matrix to study of the stochastic electromagnetic fields on propagation. The principle of coherence tensor holography is proposed in Chapter 8 and experimentally demonstrated for the first time. At last, conclusions and future works have been given

Diiodidobis(1-methyl­imidazole-κN 3)cadmium(II)

In the title compound, [CdI2(C4H6N2)2], each Cd atom is coordinated by two N atoms from two 1-methylimidazole and two iodido ligands. The Cd atom has a distorted tetrahedral coordination. Inter­molecular C—H⋯I hydrogen bonds link the monomeric units, generating a one-dimensional supra­molecular chain along the a axis

Language Learning Strategies and English Proficiency: A Study of Chinese Undergraduate Programs in Thailand

The purpose of this study was to investigate the use of language learning strategies by undergraduate students: the extent of use of language learning strategy categories in the Oxford Taxonomy, and the relationship between the use of language learning strategies and English proficiency. Two hundred fifty four Chinese undergraduate students (123 male and 131 female) in Assumption University participated in the study. The results showed that the students were medium users of overall strategies, Compensation Strategy was the most frequently used, and Memory Strategy category was the least used. A positive correlation was found between the use of language learning strategies and the English proficiency, which were indicated by students’ grades and self-efficacy. Suggestions are offered for future research

catena-Poly[[bis­(1-methyl­imidazole-κN 3)zinc(II)]-μ-isophthalato-κ2 O 1:O 3]

In the solid state, the title compound, [Zn(C8H4O4)(C4H6N2)2]n, exhibits the existence of polymeric zigzag chains extending along the a axis. Each ZnII ion is coordinated by two N atoms [Zn—N = 1.996 (6) and 2.032 (5) Å] and two O atoms [Zn—O = 1.930 (4) and 1.976 (4) Å] in a distorted tetra­hedral geometry. Weak C—H⋯O inter­actions contribute to the crystal packing stability

Corruption of the “American Dream” in Death of a Salesman: A Thematic Analysis of Arthur Miller’s Death of a Salesman

Arthur Miller published his most famous work Death of a Salesman in 1949. This play received numerous awards for its literary merit, including the Pulitzer Prize for drama and it is regarded by many critics as the perfect embodiment of the modern American drama. Willy Loman, the hero of the play, is caught-up in the “American Dream” which consists of a genuine and determined belief that in America all things are possible to all men regardless of birth or wealth. If you work hard enough you will achieve anything. However, Miller believes that people have been ultimately misguided and Miller’s play, Death of a Salesman, is a moving destruction of the whole myth.Key words: Death of a Salesman; American Dream; corruption; traged
