1. Kim, Lucy Kyoungsook. Exploring the effects of Korean subject marking and action verbs’ repetition frequency: how they influence the discourse and the memory representations of entities and events.

Degree: PhD, Linguistics, 2015, University of Southern California

Language and memory are two of the most fundamental components of human cognition. Individuals’ linguistic performance relies greatly on memory competence. At the same time, linguistic expressions can also influence what comprehenders remember and how well they remember it. Due to the close connection between these two cognitive domains, it is important to study how linguistic descriptions can influence the representations that language users build in their minds and how those representations are reflected in discourse and memory. ❧ This dissertation investigated the interplay between language and memory in the areas of entity representation denoted by nouns and event information denoted by verbs. Combining research on nominal information and verbal information is beneficial for our understanding of language processing as they are two vital aspects of sentence meaning. ❧ In the nominal domain, I conducted three experiments to explore the effect of Korean subject case marking, more specially the difference between the nominative case marker and the topic case marker (when interpreted as marking a contrastive topic). My results show that how subjects are interpreted (e.g., a default topic or a contrastive topic) has an effect on comprehenders’ expectations about which entities will be mentioned in upcoming discourse. ❧ Furthermore, the experiments also show that the order in which characters are introduced in a story influences how well comprehenders recognize them in a memory task (i.e., a recently-mentioned entity is recognized more accurately than an earlier-mentioned entity). However, a follow-up off-line story continuation task revealed that the entity that comprehenders remembered better is not the entity they talk about frequently in story continuation. Rather, the first-mentioned character was mentioned more often in subsequent sentences. Put together, my results point to a possible disconnect between accessibility in discourse and accessibility in memory: An entity’s prominence in discourse and memory are not always parallel. This suggests that prominence is a multifaceted concept that can be a product of many different factors including: (i) how and where in the discourse an entity is introduced; (ii) who else is in the discourse; and (iii) different reading goals that can affect language processing strategies. ❧ In the verbal domain, I investigated whether and how the frequency semantics of an action verb would influence sentence processing. My results show that comprehenders’ sensicality judgment was more accurate for the sentences containing action verbs of low intrinsic repetition frequency (i.e., actions which typically only happen once or twice in a row) compared to the sentences denoting high frequency actions (i.e., actions which typically happen multiple times in a row). Moreover, in a verb recognition task, verbs of low repetition frequency were recognized more accurately than verbs of high repetition frequency. These results add to the existing literature that demonstrates the effect of other… Advisors/Committee Members: Kaiser, Elsi (Committee Chair), Pancheva, Roumyana (Committee Member), Simpson, Andrew A.

Advisors/Committee Members: Mišurec, Jiří (advisor).

Subjects/Keywords: Dizertační práce se zabývá výzkumem v oblasti optimalizace telemetrických systémů v energetice z pohledu informační bezpečnosti. Práce pojednává o současných problémech informační bezpečnosti; její definici a i o metodách; které vedou k naplnění bezpečnostních principů; a soustředí se zejména na oblast; kde jsou využívány zařízení s omezenými zdroji To z toho důvodu; že zařízení s limitovanými zdroji; tj. operační paměť; omezený přístup k elektrické energii; výkon; aj.; představují bezpečnostní rizika; která mohou ovlivňovat následně celou energetickou infrastrukturu v případě nasazení technologií v konceptu inteligentních sítí. Jsou přiblíženy dnešní vědecké výzvy v této oblasti; objasněna terminologie i legislativa; která je pro tuto oblast také velice zásadní. Hlavní část dizertační práce je následně věnována výzkumu vlastního hybridního řešení; kryptosystému. Jedná se o řešení; které nenaplňuje pouze jeden bezpečnostní princip (např. pouze autentičnost); nýbrž o řešení; které nabízí všechny požadované principy informační bezpečnosti v energetice. Je provedena hloubková analýza dnešních řešení; které jsou následně evaluovány vlastními měřeními i pomocí současné aktuální literatury. Následně je proveden návrh kombinací symetrických a asymetrických kryptografických algoritmů; tak aby byla zaručena efektivita výsledného systému; ale také zachována jeho komplexnost systému. Jedná se o kombinaci symetrických blokových algoritmů elektronické kódové knihy; zajišťující autentizaci a integritu pomocí náhodných klíčů; řetězení šifrovaného textu zajišťující důvěrnost; společně s algoritmem Diffieho-Hellmana nad eliptickými křivkami zajišťující bezpečnou distribuci a výměnu symetrických tajných klíčů. V neposlední řadě je přiblížen provedený vlastní vývoj a optimalizace hybridního kryptosystému. Je představeno vlastní řešení pro reprezentaci velkých čísel a modulární algebru v zařízení s limitovanými zdroji; které je ověřeno experimentálními měřeními. Dále je rozebrán vlastní návrh; validace a optimalizace řešení náhodných hardwarových generátorů (založených na efektivním principu kvantizační chyby a protichůdných oscilátorů). Je také řešena navržená část symetrické kryptografie; kde je využito dvou dostupných knihoven; které jsou následně znatelně optimalizovány. V neposlední řadě je představen provedený rozsáhlý výzkum kryptografie eliptických křivek a možností distribuce symetrického klíče. Jsou implementovány algoritmy pro výpočty s body eliptických křivek nad polem s prvočíselným řádem i nad polem řádu 2. Realizace pak zahrnovala více než 50 eliptických křivek různých standardů; kde největším úspěchem jsou křivky nad polem prvočísel o řádu p = 256. Tyto křivky v době řešení nebyly na takto hardwarových platformách řešeny. Nakonec jsou představeny originální výsledky výzkumu; který se zabýval vhodnou volbou křivek a studií jejich doménových parametrů z pohledu vztahu velikosti k rychlosti operací nad křivkou.; The dissertation thesis focuses on research in the optimisation of telemetry systems in energy from the perspective of information security. The thesis deals with nowadays challenges in information security; its definition as well as its methods. The main focus is on the area; where devices with limited resources such as memory or computational power are used. These devices pose security risks that may affect the entire smart grid infrastructure. Nowadays research challenges terminology and legislative; which is crucial in the defined area; are brought closer. The main part of this thesis is devoted to the research of the author’s own hybrid solution – the hybrid cryptosystem. The solution fulfils all necessary principles of information security – authenticity; confidentiality; integrity and data freshness. An analysis of today’s solutions is provided together with a complex evaluation based on own experimental measurements and available literature sources. Subsequently; a combination of symmetric and asymmetric cryptography algorithms is designed that provides both high efficiency and complexity. It is a combination of the symmetric block cyphers Electronic Code Book; which provides authenticity and integrity by using random keys; Cipher Block Chaining; which provided confidentiality; and the asymmetric algorithm of Diffie-Hellman over Elliptic Curves; which provides key agreement scheme over an unsecured channel. Further; the development and optimisation of the hybrid cryptosystem are brought in light. The proprietary solution of large number representation and modular algebra in a device with limited resources is presented and validated via own experimental measurements. Moreover; the own design is analysed and the two proposed hardware generators (based on efficient methods of quantization error and opposing oscillators) are evaluated and optimised. Additionally; the symmetric part of the cryptosystem is also investigated; where two main solutions are highly optimised. Last but not least; deep research on the cryptography of elliptic curves and the key distribution scheme is presented. Two main curve types are dealt with – over a finite field and over a field of characteristic two. The implementation included more than 50 elliptic curves of different standards. The implementation of the curves of order p = 256 has the highest impact. These curves were not addressed on such devices at the time of solution. Finally; the original research results of possible speed optimisation via using special elliptic curves are introduced. The relationship between curve domain parameters and point computational efficiency is studied. This last part brings also promising results for the field of effective cryptographic algorithm – the lightweight cryptography.
