This paper analyzed the lexical density of the adjective and noun clauses in an English textbook for senior high school students in Indonesia. It aimed to discover whether or not the textbook was suitable for the students in terms of lexical density. The researchers employed a content analysis approach to analyze data. There were 116 sentences, containing adjective and noun clauses, which were investigated. The researchers implemented the lexical density theory and the lexical density indicators to determine the average level of the lexical density measurements. Results showed that there were three lexical density levels found in those adjective and noun clauses. The three levels were low, medium, and high. The average level of the lexical density obtained from the adjective and noun clauses in the textbook was 47%, which was categorized as low lexical density. Thus, the researchers concluded that the English textbook for the tenth-grade students published by the Indonesian Government was appropriate for the students.

This paper entitled "Lexical Density and Grammatical Intricacy in Debaters' speeches (Case Study of National University Debating Championship 2018)" discusses the lexical density and grammatical intricacy to identify the level of lexical density and grammatical intricacy in debaters' speeches conducted by means of descriptive qualitative method. The theories supporting this thesis are the ones proposed by Ure, Halliday, and Simon Quinn. The data source in this thesis were debate speech from Main Grand Final round of NUDC 2018 which are Opening Government team (Prime Minfister and Deputy Prime Minister) and Opening Opposition team (Leader of the Opposition and Deputy Leader of the Opposition) taken from youtube video of NUDC 2018, Malang. The data in this study were lexical items for lexical density and clauses for grammatical intricacy. The step passed in this analysis are collecting the data by transcribing the debate speech into text, identifying the lexical items and clauses, and concluding the analysis. The result of this thesis shows that lexical density and grammatical intricacy of Prime Minister = 40.95 % and 3.43, Deputy Prime Minister = 42.44% and 2.72, Leader of the Opposition = 46.14% and 2.91, and Deputy Leader of the Opposition = 47.90% and 3. Thus, both the level of lexical density and grammatical intricacy in debaters' speeches account for higher density and intricacy, so debaters' speeches represent much information due to many lexical items as the proportion of running words and indicate that clause complex is more dominant than simple sentence.

The research aims to develop the method of contrastive analysis of linguistic creativity in discourse. The present study attracting two typologically different discourses, the cinematic discourse and the discourse of children's literature, demonstrates the 5-stage algorithm of contrastive frequency and contingency analysis of linguistic creativity parameters in all language levels, phonological, morphological, word building, lexical, syntactic and graphic. The algorithm helps distinguish between discourse creative and non-creative use of linguistic means, with the basic criterion of pragmatic relevance serving to make the decision between the two. The procedure is applied to the discourse data sets which amount to 104,543 text signs of two cinematic comedies and four children's humorous short stories; to assess the pragmatic relevance of linguistic creativity parameters, we relied on the humorous effect produced with the use of linguistic means. The main research focus of the study is the parametric activity and parametric distribution within the lexical level of the discourses contrasted. Apart from the general parametric results contrasting all the parameters of linguistic creativity within the lexical level, we present the results of two distinct parameters, socio-communicative register shifts and professional code shifts, which clearly specify the differences in their discourse creative and non-creative use in the cinematic discourse and the discourse of children's literature. The results show that enhanced general parametric activity is not contingent with discourse creative parametric activity as the pragmatically relevant modifications of parameter use display diversity in two discourse types. The developed method of contrastive analysis and the results obtained will stimulate further research in cross-discourse studies of linguistic creativity, which might disclose new dimensions in discourse construal and discourse productivity.

This dissertation proposes a high-power, high-frequency and high-density three-level parallel resonant converter for capacitor charging. DC-DC pulsed power converters are widely used in military and medical systems, where the power density requirement is often stringent. The primary means for reducing the power converter size has been to reduce loss for reduced cooling systems and to increase the frequency for reduced passive components. Three-level resonant converters, which combine the merits of the three-level structure and resonant converters, are an attractive topology for these applications. The three-level configuration allows for the use of lower-voltage-rating and faster devices, while the resonant converter reduces switching loss and enhances switching capability. This dissertation begins with an analysis of the influence of variations in the structure of the resonant tank on the transformer volume, with the aim of achieving a high power density three-level DC-DC converter. As one of the most bulky and expensive components in the power converter, the different positions of the transformer within the resonant tank cause significant differences in the transformer's volume and the voltage and current stress on the resonant elements. While it does not change the resonant converter design or performance, the improper selection of the resonant tank structure in regard to the transformer will offset the benefits gained by increasing the switching frequency, sometimes even making the power density even worse than the power density when using a low switching frequency. A methodology based on different structural variations is proposed for a high-density design, as well as an optimized charging profile for transformer volume reduction. The optimal charging profile cannot be perfectly achieved by a traditional output-voltage based variable switching frequency control, which either needs excess margin to guarantee ZVS, or delivers maximum power with the danger of losing ZVS. Moreover, it cannot work for widely varied input voltages. The PLL is introduced to overcome these issues. With PLL charging control, the power can be improved by 10% with a narrow frequency range. The three-level structure in particular suffers unbalanced voltage stress in some abnormal conditions, and a fault could easily destroy the system due to minimized margin. Based on thoroughly analysis on the three-level behaviors for unbalanced voltage stress phenomena and fault conditions, a novel protection scheme based on monitoring the flying capacitor voltage is proposed for the three-level structure, as well as solutions to some abnormal conditions for unbalanced voltage stresses. A protection circuit is designed to achieve the protection scheme. A final prototype, built with a custom-packed MOSFET module, a SiC Schottky diode, a nanocrystalline core transformer with an integrated resonant inductor, and a custom-designed oil-cooled mica capacitor, achieves a breakthrough power density of 140W/in3 far beyond the highest-end power density reported (<100 W/in3) in power converter applications. ; Ph.

Sanskrit literature abounds in lexicons. Amarakośa is the most celebrated and authoritative ancient thesaurus of Sanskrit. There are references to various lexicons in many ancient Sanskrit texts, but none of these except for Dhanvantari's and Amarasiṃha's are extant. Between the two, the latter's work Nāmaliṇgānuśāsana popularly known as Amarakośa is very familiar to every student of Sanskrit. The actual name of the book 'Nāmaliṇgānuśāsana' means instruction concerning nouns and gender. It is divided into three kāṇḍas (volumes). Eachkāṇḍa is divided into Vargas depending on the subject they deal with. A list of more than 220 plants is mentioned with all the synonyms in the four Vargas. The plants that are revealed in the Amarakośacan be classified into huge trees, edible fruit trees, shrubs, herbs, creepers, water plants, grasses, pulses, cereals, wild cereals and others. Plants that are generally used for incensing, perfumery and cosmetics for human consumption are mentioned in the Manuṣhya Varga. In the Vaiśyavarga crops of commercial value are included.
