Low cost technology applied to thermometry of grains

Modern agriculture demands investments in technology that allows the farmers to improve productivity and quality of their products, aiming to establish themselves in a competitive market. However, the high costs of acquiring and maintaining such technology may be an inhibiting factor to its spread and acceptance, mainly to a large number of small grain Brazilian farmers, who need low cost innovative technological solutions, suitable for their financial reality. Starting from this premise, this paper presents the development of a low cost prototype for monitoring the temperature and humidity of grains stored in silos, and the economic implications of cost/benefit ratio of innovative applications of low cost technology in the process of thermometry of grains. The prototype was made of two electronic units, one for acquisition and another one for data reception, as well as software, which offered the farmers more precise information for the control of aeration. The data communication between the electronic units and the software was reliable and both were developed using low cost electronic components and free software tools. The developed system was considered as potentially viable to small grain Brazilian farmers; it can be used in any type of small silos. It provided reduction of costs of installation and maintenance and also offered an easy expansion system; besides the low cost of development when compared to similar products available in the Brazilian market.

The accuracy potential of Galileo E5/E1 pseudoranges for surveying and mapping

In the paper we discuss the potential of the new Galileo signals for pseudorange based surveying and mapping in open areas under optimal reception conditions (open sky scenarios) and suboptimal ones (multipath created by moderate to thick tree coverage). The paper reviews the main features of the Galileo E5 AltBOC and E1 CBOC signals; describes the simulation strategy, models and algorithms to generate realistic E5 and E1 pseudoranges with and without multipath sources; describes the ionosphere modeling strategy, models and algorithms and discusses and presents the expected positioning accuracy and precision results. According to the simulations performed, pseudoranges can be extracted from the Galileo E5 AltBOC signals with tracking errors (1-σ level) ranging from 0.02 m (open sky scenarios) to 0.08 m (tree covered scenarios) whereas for the Galileo E1 CBOC signals the tracking errors range between 0.25 m to 2.00 m respectively. With these tracking errors and with the explicit estimation of the ionosphere parameters, simulations indicate real-time open sky cm-level horizontal positioning precisions and dm-level vertical ones and dm-level accuracies for both the horizontal and vertical position components.

The Role of the (In)visible and the Secret in the Translation of Harryette Mullen s Muse & Drudge

This paper, based on Jacques Derrida’s thoughts in Des Tours of Babel, addresses the issue regarding the (in)visible in translation, by arguing that the latter, beyond the traditional conception of communication, produces a complex set of relations between the visible and the invisible, which highlights the values of the non-dit and the secret that take place in their relation to interpretation. This line of thought underpins the discussion of my translation of two poems from Muse & Drudge (1995), by the African-American poet Harryette Mullen, whose dense poetry displays un(expected) possibilities of meanings and associations that proliferate in translation. It is argued that every act of translation entails a relationship between that which is translated (and made visible or intelligible through this act) and that which remains invisible and secret by resisting a definitive translation, which, as such, requires further interpretations in search for intelligibility (or “visibility”). We analyze the extent to which such relation between the visible and the invisible takes part in the translation of the notion of blackness raised by Mullen’s poems and how her translated poetry dialogues with issues of reception in Brazilian culture.

O estilo do rei: o diálogo entre O Rei Leão, da Disney, e Hamlet, de Shakespeare, sob uma perspectiva semiótica

This work consists of a semiotic analysis of the animation motion picture The Lion King (1994), by the Walt Disney Animation Studios, describing its intertextual relation with Hamlet, by Shakespeare, considering Disney’s individuality, its style. In order to study style in texts, we use discursive semiotics theory, highlighting Discini’s work (2013) and the concept of discursive settings. Hence, a deep discussion about The Lion King’s style, compared to the Shakespeare’s play, is established. The movie, once a syncretic text, requires advanced studies on Expression Plane, its plastic, musical and verbal/phonic aspects. We find these studies in the work of José Luiz Fiorin (2009), Lúcia Teixeira (2009), Ana Claúdia de Oliveira (2009), Jean-Marie Floch (2009) and Antônio Vicente Pietroforte (2008). We note how a syncretic text makes the discursive settings more complex by assembling plastic and sonorous materials in semissimbolic relation. Once defined The Lion King’s style, we analyze the way it justifies the intense popularity of this kind of animation features. Finally, it is important to understand how Disney uses in its style not only discursive settings, but also passional settings, revealing its own way to stir emotions on the spectator

A recepção de Shakespeare na Alemanha

This is an article about a decisive moment in the formation of Western modern literature. We are talking about Lessing’s criticism of the excessive influence of neoclassical French theatre on German theatrical production. Lessing considered that the aristocratic model imported from France did not correspond to German society’s context at all – society which had already been marked by an incipient bourgeois mode of life. So the German critic dedicated his theoretical efforts to affirm the necessity and to raise possibilities about a literary production which had more consonance with what he considered to be the German Zeitgeist. It is in Shakespeare’s work that Lessing found his answer, and this fact will unleash the appearing of the Sturm und Drang movement and will consequently give birth to an incipient bourgeois literature. So we analyze here the way this Shakespearian influence happens and its relevance in the formation of a bourgeois literature.

Hamlet's Ophelia: The Changing Perceptions of Suicide, Death, and Madness in the Elizabethan and Victorian Periods

William Shakespeare's Hamlet, Prince of Denmark has been the source of question, debate, and research since its theatrical debut. In the midst of readings performances and one particular question has remained open and unresolved: was Ophelia's death an accident or a suicide? Some see Ophelia's death as an accident; others see it as a suicide resulting from the accumulation of a series of unfortunate events: her rejection by her boyfriend, her father’s murder, and her possible pregnancy. This paper will explore that age-old question from the perspectives of two historically different audiences: those of sixteenth-century and nineteenth-century England. I will argue that, despite the 300-year expanse between these two audiences, both emerged with the same conclusion: Ophelia's death was accidental. However, cultural and scientific changes affected the reasons why each came to that conclusion.

Holling Family Award Reception

John Holling, a 1912 graduate of the University of Nebraska who died in 1988, established the "Peter and Anna Holling Fund" in 1973 with his sisters, Hattie and Elvena Holling, the only other surviving children at the time. Their siblings, Gustave, Emil, and Rose also had contributed to the estate. The Hollings were a pioneer farm family of German-Danish descent. Peter Holling settled in the Grand lsland area in the 1870s after missing a westbound Union Pacific work-train that he had originally boarded in Iowa.
