  • Uncovering the cellular pathways involved in Lowe syndrome

    • Authors: Farber, Leslie (2006)

  • Lowe syndrome is an X-linked recessive disorder characterized by congenital cataracts, mental retardation, and abnormal kidney functions. Loss of function mutations in the OCRL1 gene lead to Lowe syndrome in all patients to date. The ocrll protein was previously identified as a PIP2 5-phosphatase localized to the trans-Golgi network. However, the mechanism through which loss of ocrll leads to the Lowe syndrome phenotype is still unknown. The aim of these studies was to define the cellular role of the PIP2 5-phosphatase, OCRL1, and its paralog, INPP5B. The first goal of this project was to study the ocrll paralog, INPP5B, in order to understand why Inpp5b can compensate for ocrll-defi...

  • Understanding the figurative language of tropes in natural language processing using a brain-based organization for ontologies

    • Authors: Keuper, Christine M. (2006)

  • Language communication is the successful interpretation of the speaker’s communicative intent. When Shakespeare writes, we see the intent in Romeo’s words, but it is lost again when we attempt to express it using a computer model for language; a model with an ability to handle tropes (metaphor, metonymy, synecdoche and irony) is needed. The goal of this model is to correctly interpret the nouns that occur within these tropes. Early computer language models had not worked well when they encountered tropes, yet the brain handled them easily. These early models concentrated on the language functions of the left temporal lobes of the brain; perhaps the models worked poorly because they...

  • Understanding the performance determining processes in dye sensitized solar cells

    • Authors: Marton, Andras (2006)

  • The work presented in this thesis is aimed at optimizing the performance of the dye-sensitized solar cell (DSSC). Chapter 1 presents a brief overview of the history of solar cells and introduces the reader to the components, mechanisms and characterization techniques relevant to the DSSC. Chapter 2 describes the effect pH has on electron injection and collection processes in DSSC's. Charge collection efficiency, and not the electron injection yield, was related to the TiO2 surface protonation-deprotonation equilibria. In Chapter 3 we examine alternate redox mediators to optimize the regeneration of the oxidized sensitizer while maximizing open circuit voltage (Voc). Bipyrazine based r...

  • Understanding the process of multi-document summarization: Content selection, rewriting and evaluation

    • Authors: Nenkova, Ani (2006)

  • Recent years have seen unprecedented interest in news aggregation and browsing, with dedicated corporate and research websites becoming increasingly popular. Generic multi-document summarization can enhance users' experiences with such sites, and thus the development and evaluation of automatic summarization systems has become not only research, but a very practical challange. In this thesis, we describe a general modular automatic summarizer that achieves state of the art performance, present our experiments with rewrite of generic noun phrases and of references to people, and demonstrate how distinctions such as familiarity and salience of entities mentioned in the input can be auto...

  • Unramified representations of p-adic groups on spherical varieties

    • Authors: Sakellaridis, Loannis (2006)

  • The description of irreducible representations of a group G can be seen as a question in harmonic analysis; namely, decomposing a suitable space of functions on G into irreducibles for the action of G x G by left and right multiplication. For a split p-adic reductive group G over a local non-archimedean field, unramified irreducible smooth representations are in bijection with semisimple conjugacy classes in the "Langlands dual" group. In the first part of this work, we generalize this description to an arbitrary spherical variety X of G as follows: Irreducible quotients of the "unramified" Bernstein component of C°°(X) (or, more generally, CC°(X, LT), where L,y is a G-linear line b...

  • Unsupervised induction of latent semantic grammars with application to parsing

    • Authors: Olney, Andrew McGregor (2006)

  • This dissertation investigated the utility of latent semantic information for unsupervised grammar induction. Utility was directly measured by the relative performance of induced latent semantic grammars in parsing sentences and by the relative performance of induced grammars on making meaning judgments. Latent semantic grammars did not outperform the state of the art method for unsupervised parsing. However, latent semantic grammars performed as well or better than all other methods, indicating that latent semantic parsing is worthy of future research. Latent semantic grammars had equivalent performance to Latent Semantic Analysis on comparative meaning tasks, suggesting that latent ...

  • Use of nondestructive spectroscopy to assess chlorophyll and nitrogen in fresh leaves

    • Authors: Ding, Pinghai (2006)

  • CHAPTER 3: The accuracy of nondestructive optical methods for chlorophyll (Chl) assessment based on leaf spectral characteristics depends on the wavelengths used for Chl assessment. To determine the optimum wavelengths for Chl assessment (OWchl) using reflectance spectroscopy, almond (Prunus dulcis (Mill.) D.A. Webb `Nonpareil'), poplar (UCC-1, a hybrid of Populus trichocarpa x P. deltoides, Union Camp, Princeton, NJ) and apple (Malus domestica Borkh `Fuji') trees were grown at different rates of nitrogen (N) fertilization to produce leaves with different Chl concentrations. Spectral reflectance of leaf discs was measured using a spectroradiometer (300 nm to 1100 nm at 1 nm intervals)...

  • Use of Ontologies and Probabilistic Relational Models to Aid in Cyber Crime Investigation Decision Support

    • Authors: Lazarevich, Aleksandar (2006)

  • The field of computer forensics is continuously evolving and is still in its infancy when compared to other fields in the world of information technology. If one were to compare computer forensics to fields such as data mining, the immaturity of forensics becomes even more apparent and one can see that much more research is needed. Indus-try has developed many automated tools to perform data mining techniques but each implements a proven concept that has been validated. Even though these data mining concepts may have not been applied to ontologies, the precepts that the software is based on are defined in basic database theory and schemas. Software tools for computer forensics have be...

  • Using Animation in Microsoft PowerPoint to Enhance Engagement and Learning in Young Learners with Development Delay

    • Authors: Parette, Howard P.; Hourcade, Jack; Blum, Craig (2011-03)

  • The article examines how early childhood educators can use the Microsoft PowerPoint presentation software to engage students with learning disabilities in literacy lessons. It presents instructions to teachers on how to incorporate animations, add photographic images, and present audio clips in content presented to students through PowerPoint and explores ways in which the use of animation can be used to promote time on task learning opportunities as well as visual prompts for student responses. It also describes additional software which can be used in literacy instruction including Microsoft Photo Story 3 and the web site Book Builder, located at www.bookbuilder.cast.org.

  • Using cognitively inspired agents and information supply chains to anticipate and share information for decision making teams

    • Authors: Sun, Shuang (2006)

  • September 11 and hurricane Katrina have shown that timely information is important not only for disaster prevention but especially valuable in effective disaster response. From the point of view of information and communication technologies, the challenge is how to coordinate information sharing effectively among members of a complex decision-making team (e.g. the first responders for a disaster). A common difficulty is to provide useful and time-sensitive information to team members quickly but at the same time not overwhelm them with irrelevant information. This problem has also been encountered in other application domains that require effective communication in a team environment:...

  • Using domain knowledge for text mining

    • Authors: Dayanik, Aynur (2006)

  • Text mining concerns the automated analysis of textual data to store, retrieve, organize and extract useful information from textual data. Text mining systems usually rely on document collections or training data prepared for a particular application. However, in practice, external knowledge is also available in external databases, reference books, web pages and many other sources. This thesis concerns the use of external knowledge for text mining to improve the performance of text mining systems. First we focus on using domain knowledge for clustering and text retrieval for bioin¬formatics. We describe a method for clustering biological data by exploiting the inter-linked structure ...

  • Using ionic liquid as solvent for coupling, and halogen exchange reactions

    • Authors: Nguyen, Thi Hong Anh.;  Advisor: Phan, Thanh Son Nam.; Truong, Vu Thanh. (2018)

  • In this research, 1-alkyl-3-methyl imidazolium bromide ionic liquids were successfully synthesized under microwave conditions. After that, 1-alkyl-3-methyl imidazolium hexafluorophosphate [AMIM]PF6 ionic liquid was prepared by anion exchange reaction of dialkylimidazolium bromide with hexafluorophosphoric acids. The structural properties of prepared ionic liquids were characterized by using Nuclear Magnetic Resonance (1H, 13C NMR) and Mass Spectrometry (MS) analysis. More interestingly, the results showed that dialkylimidazolium ionic liquid could effectively act as green solvents for coupling reactions, and halogen exchange reaction with high conversion under low temperature and shor...
