A 0.6 V Current Reference Based on the MOSFET Forward-Body-Biased ZTC Condition
No full textThis work presents a self biased current reference circuit based on the MOSFET Zero Temperature Coefficient (ZTC) condition. To achieve lower supply voltage (VDD) operation, the proposed circuit employs forward body biasing technique to decrease the MOSFET ZTC biasing point. In addition, a body-driven pseudo differential Operational Transconductance Amplifier (OTA) is used to further reduce the minimum supply voltage. From transitor-level simulations, the current reference is predicted to have an Effective Temperature Coefficient (TCeff ) of 65 ppm/oC from -55 to 125 oC and a fabrication sensitivity of s/u= 6.5 %, including process and mismatch variability. The power supply sensitivity is around 0.75 %=V for this new reference
Incursões pela gênese do romance "Memórias sem malícia de Gudesteu Rodovalho", de Gilberto de Alencar
No full textThis paper aims at to present a critical text and some aspects of Gilberto de Alencar s
creation process into a previously chosen corpus from his novel Memórias sem malícia de
Gudesteu Rodovalho from two manuscript that we ll call manuscript (MsA), manuscript
(MsB) and two printed editions: the first one, of 1946, sponsored by the author himself and
printed by Gazeta Commercial de Juiz de Fora, the second one, of 1957, printed by Agir
Editions from Rio de Janeiro. Considering that the textual criticism aims at the ways of the
edited text and the genetic criticism at the creation of the text itself, we tried to follow step
by step the author s creation. Therefore we proceeded to the handwritten comparison of the
genetic dossier witch is formed by four documents: two manuscripts and two life editions.
By means of the register of the variants and a study of the erasures we tried to show the
alterations basically understood by the four erasures functions in a text such as: to
substitute, to add, to suppress and to displace words expressions and paragraphs then
relating the erased segments with the text as a whole. The annex was filled with concerning
data to complementary documentation related directly to the analyzed documents in the
dossier. The contact with the author s work manuscript helps to preserve the social history
of man in his cultural trajectory.Esta tese propõe-se a apresentar um texto crítico e alguns aspectos do processo de
criação de Gilberto de Alencar, em um corpus, previamente selecionado do romance Memórias
sem malícia de Gudesteu Rodovalho, a partir de dois manuscritos, a que chamamos manuscrito
A (MsA), manuscrito B (MsB), e de duas edições impressas. A primeira, de 1946, custeada
pelo próprio autor, foi feita nas oficinas da Gazeta Comercial de Juiz de Fora. A segunda, de
1957, pela editora Agir, Rio de Janeiro. Considerando que a Crítica Textual tem por objeto os
caminhos do texto editado e a Crítica Genética, os caminhos da criação, tentamos acompanhar
o autor em seu caminho. Para tanto, procedemos ao cotejo do dossiê genético, formado pelos
quatro documentos: dois manuscritos e duas edições em vida. Mediante o registro das variantes
e um estudo das rasuras, procuramos dar uma visão das alterações, basicamente compreendidas
pelas quatro funções da rasura, num texto, ou seja: substituir, acrescentar, suprimir e deslocar
palavras, expressões e parágrafos, para, então, relacionar os segmentos rasurados com a
totalidade do texto. O anexo foi preenchido com dados concernentes à documentação
complementar, que se encontra relacionada diretamente aos documentos analisados no dossiê.
O contato com os manuscritos da obra é um ato de resgate que preserva a construção da
história social do homem em sua trajetória cultural
Diffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
A 1.9 nw, sub-1 v, 542 pa/v linear bulk-driven ota with 154 db cmrr for bio-sensing applications
No full textIn this paper, a new technique for improvement on the DC voltage gain, while keeping the high-linearity in symmetrical operational transconductance amplifier (OTA) bulk-driven (BD) topology is proposed. These features are achieved by allying two topological solutions: enhanced forward-body-biasing self-cascode current mirror, and source degeneration. The proposed concept is demonstrated through simulations with typical process parameters and Monte Carlo analysis on nominal transistors of the CMOS TSMC 180 nm node. Results indicate that the proposed OTA can achieve a very small transconductance, only 542 pA/V while keeping a voltage gain higher than 60 dB, 150 dB CMRR, and high linearity of 475 mVpp (1% THD), consuming only 1.9 nW for a supply voltage of 0.6 V. This set of features allows the proposed OTA to be an attractive solution for implementing OTA-C filters for the analog front-ends in wearable devices and bio-sensing

No full textCan archives of audiovisual TV interviews be used to make authors more visible to students, and thereby reduce the learning gap between native and non-native language speakers in college classes? We examined students in a college course who learned about one scholar's ideas through watching an audiovisual TV interview (i.e., visible author format) and about another scholar's ideas through reading a formal text description (i.e., invisible author format). For the invisible author, native language speakers scored significantly higher than the non-native language speakers on a corresponding exam question (i.e., a cognitive measure), generated more words on the exam question (i.e., a motivational measure), and mentioned the author's name more often in answering the exam question (i.e., an affective measure). For the visible author, the groups did not differ on any of these measures. These findings provide evidence for the idea that making the author visible through audiovisual TV interviews can eliminate the learning gap between native and non-native language speakers. 3 Universities around the world serve students who are non-native speakers of th
The vanishing author in computer-generated works: a critical analysis of recent Australian case law
No full textAbstract
The use of software is ubiquitous in the creation of many copyright works, yet the requirement in copyright law that every work have a human author who engages in independent intellectual effort means that its use may prevent copyright subsistence. Several recent Australian cases have refocused attention on authorship as an essential criterion of copyright subsistence, and these cases suggest that much computer-produced output may be authorless and thus lack copyright protection. This article, the first in a two-part series, analyses how each case deals with the question of authorship of computer-produced works and why the use of software diminishes copyright protection for a significant number of computer-generated works. The article critiques the application of conventional notions of human authorship developed in the pre-computer age to modern productions and suggests alternative approaches to authorship that satisfy both the major objectives of copyright policy and the need to adapt to the computer age. The article argues that, without a broader judicial approach to authorship of computer-generated works, Parliament must remedy the lacuna in protection for these ‘authorless’ works. Possible solutions for reform are suggested. In a forthcoming article, the author comprehensively examines those reform proposals
The construction of Karen Karnak: The multi-author-function
No full textThis thesis is situated within the comparatively recent developments of Web 2.0 and the emergence of interactive WikiMedia, and explores the mode of authorship within a Read/Write culture compared to that of a Read/Only tradition. The hypothesis of this study is that the role of the audience has become merged with the author, and as such, represents new functions and attributes, distinct from a more conventional concept of authorship, in which the roles of audience and author are more separate. Read/Write and participatory culture, as defined by this study, is focused on collaboration, and includes the influences of D.I.Y. culture, Open-Source practices and the production of text by multiple authors. Multi-authorship presents a re-thinking of several concepts which support the notion of the individual author, since the focus of multi-authorship is not on attribution and ownership of a finished text, but on the continued malleability of a text. Modes of multi-authorship, demonstrated in the use of the pseudonyms Alan Smithee and Karen Eliot, represent declarative authors whose names signify multiple origins, whilst concurrently indicating a distinct body of work. The function of these names form an important context to this study, since primary research involves the construction of an experimental mode of multi-authorship utilising WikiMedia technology and the interaction of thirty nine participants, who are invited to create a body of work under the collective pseudonym Karen Karnak. The data generated by this experiment is analysed using aspects of Michel Foucault's author-function to identify and determine power structures inherent in the WikiMedia context. The interplay of power structures, including concepts such as identity, ownership and the body of work, affect the resulting mode of authorship and contribute to the construction of Karen Karnak, suggesting further areas of research into the emerging multi-author
