Texto completoVaz, Bruno Rafaelo Lopes. "A RECEPÇÃO DE FREGE DA NOÇÃO KANTIANA DE EXISTÊNCIA". Universidade Federal de Santa Maria, 2006. http://repositorio.ufsm.br/handle/1/9041.
Texto completoIn this work the relationship between two famous conceptions of existence is investigated. The first, proposed by Kant, excludes the concept of existence from the set of possible predicates or properties of objects. The second, later proposed by Frege, treats the concept of existence as a higher-level predicate, i.e., it presents this concept as a predicate of predicates rather than as a predicate of objects. A closer look at these conceptions reveals, however, that despite this similarity it would be premature to identify their conceptions, because there are differences with regard to the systems in which they are embedded as well as differences with regard to the aims that they pursue. The present work tries to show that Kant developed his conceptions of the concept of existence in an epistemological context whose aim was, as he makes clear in his opus magnum, to warrant the claim that every knowledge should have besides a conceptual element also a counterpart arising from the intuition. Frege, on the other hand, develops his conception in a basically logical context, in which the treatment of expressions is submitted to strong rigor. The aim of the present work is to compare Kant s and Frege s approaches in order to answer the question whether there are significant differences between their characterizations of the concept of existence and, if so, which ones. One important result of the present work is that the differences in their positions are consequences of some differences between the contexts in which they are developed. Another result is that their conceptions include some common theses, such as the claim that the concept of existence is not a concept that can be used to characterize an object, or the claim that existential statements constitute an odd type of judgement whose appearance in natural languages suggests an erroneous reading of them. On the other hand, however, there are significant differences between the positions advocated by Kant and Frege as, for instance, differences with regard to the possibility of deriving statements of existence from the analysis of concepts, a possibility that is categorically denied by Kant but admitted, with some qualifications, by Frege. The third important result finally is that Frege s conception of existence must be regarded as an improvement, not as a mere repetition, of Kant s conception.
Este trabalho apresenta um estudo da relação entre duas célebres abordagens do conceito de existência. A primeira, apresentada por Kant, exclui o conceito de existência do conjunto dos possíveis predicados ou propriedades de objetos. A segunda, apresentada mais tarde por Frege, trata o conceito de existência como um predicado de nível superior, i.e., apresenta o conceito como um predicado de predicados, e não como um conceito que se aplica diretamente a objetos. Apesar de ambas abordagens se parecerem muito entre si, um estudo mais aprofundado de ambas servirá para mostrar que a diferença entre os sistemas teóricos em que se inserem, bem como entre os objetivos que visavam, sugerem que seria precipitado identificá-las. Tentar-se-á mostrar, neste trabalho, que Kant desenvolve suas concepções a respeito deste conceito num contexto epistemológico, tendo em vista, como fica claro na sua opus magnum, garantir o requisito de que todo conhecimento deve ter, além do elemento conceitual, também uma contraparte advinda da intuição. Frege, por sua vez, apresenta suas teses a respeito do tema dentro de um contexto basicamente lógico, onde se fazia necessária uma rigorização do tratamento das expressões que compõem a linguagem. O objetivo do presente trabalho consiste em estudar a abordagem de cada autor separadamente, e, em seguida, comparar as duas abordagens a fim de mostrar se existem diferenças significativas entre as caracterizações que ambos deram ao conceito de existência, e, em caso positivo, mostrar quais seriam estas diferenças. Dentre os principais resultados a que se chegou, destacam-se as diferenças que as posições dos autores possuem; diferenças sugeridas pela diferenciação entre os contextos de apresentação da temática nos dois autores. Também se destaca a equivalência das teses de ambos em alguns aspectos, como por exemplo, a tese segundo a qual o conceito de existência não se encontra entre os conceitos que podem servir para caracterizar um objeto, ou a alegação de que os enunciados existenciais constituem um tipo único de juízo, cuja aparência nas linguagens naturais sugere uma leitura errônea dos mesmos. Deve-se mencionar, por outro lado, a diferença significativa de posições de Kant e Frege em outros aspectos, como no que tange à possibilidade de se derivar existência por meio de análise conceitual, possibilidade negada categoricamente por Kant e admitida, com algumas ressalvas, por Frege. Por fim, destaca-se a possibilidade de se interpretar as teses de Frege como um aperfeiçoamento, mas não como uma mera repetição, das teses de Kant.

Texto completoSingle molecule fluorescence techniques enable to monitor the molecular dynamics and interactions in the biological processes. Nowadays, the molecular dynamics of proteins is principally accompanied by external fluorescent labeling. However, an attached molecule might perturb the protein dynamics. Fortunately, a vast majority of proteins contain tryptophan and tyrosine that absorb and emit light in the UV range of 260-400 nm. These intrinsically fluorescent amino acids yield limited absorption cross-section, quantum yield, and photostability in the UV range, which hampers single protein UV autofluorescence detection. In order to reach single molecule sensitivity of protein UV autofluorescence, we develop a time-resolved UV confocal microscope with 266 nm and 295 nm excitations and the detection optics in the near UV. Based on the total fluorescence time traces, we quantify the single molecule sensitivity, the effect of photostabilization techniques on the protein autofluorescence. Fluorescence correlation spectroscopy (FCS) and time-correlated single photon counting (TCSPC) measurements provide quantitative information on the detection volume, the fluorescence enhancement factors, and the accelerated photokinetics of the UV emitting molecules in the presence and absence of the aluminum (Al) nanostructures. Using p-terphenyl as a bright UV emitting molecule, we optimize the Al plasmonic nanostructures to enhance the single molecule fluorescence. Under certain conditions, the light confinement and fluorescence enhancement in the aluminum nanostructures enable to apply the UV plasmonics for the single molecule detection of label-free beta-galactosidase protein

Texto completoThis study aims to analyze the relationship between thehuman will with the problem of evil from the of Augustine thought. Since your youth Augustine questioned about the problem of evil and saw in the Manichean dualism a reasonable response as a solution to the problem. After nearly a decade in Manichaeism, Aurelio Augustine moved to Rome and then Milan, where he participated in Platonic studies group. However, the contact of Augustine, in Milan, with the Catholic Bishop Ambrose led him to conversion to Catholicism and the abandonment of Manichaeism. From this, Augustine prepared your theory about evil, that relate directly to human will. In this perspective, evil is not a being, as he taught the Manichaeism, but as a result of the free will of the human being by your will stop wanting want God as supreme good for wanting a well more than himself. In this way, the desire human being deprived of God, corrupting the relationship between the divine and the human.
Este estudo visa analisar a relação entre a vontade humana com o problema do mal a partir do pensamento de Agostinho. Desde a sua juventude Aurélio Agostinho questionava-se sobre o problema do mal e viu no dualismo maniqueísta uma resposta razoável como solução para o problema. Depois de quase uma década no maniqueísmo, Agostinho mudou-se para Roma e posteriormente, Milão onde participou de grupo de estudos platônicos. Contudo, o contato de Agostinho, em Milão, com o bispo católico Ambrósio levou-o a conversão ao catolicismo e com isso o abandono do maniqueísmo. A partir disso, Agostinho elaborou sua teoria sobre o mal, a que está relacionada diretamente à vontade humana. Nessa perspectiva, o mal não é um ser, como ensinava o maniqueísmo, mas fruto da vontade livre do ser humano que, por livre vontade, deixa de querer Deus como bem supremo para querer um bem inferior ou a si mesmo. Dessa forma, pela vontade o ser humano se priva de Deus corrompendo a relação entre o divino e o humano.

Texto completoIn Magnetic Resonance Imaging (MRI), the increase of the static magnetic field strength is used to provide in theory a higher signal-to-noise ratio, thereby improving the overall image quality. The purpose of ultra-high-field MRI is to achieve a spatial image resolution sufficiently high to be able to distinguish structures so fine that they are currently impossible to view in a non-invasive manner. However, at such static magnetic fields strengths, the wavelength of the electromagnetic waves sent to flip the water proton spins is of the same order of magnitude than the scanned object. Interference wave phenomena are then observed, which are caused by the radiofrequency (RF) field inhomogeneity within the object. These generate signal and/or contrast artifacts in MR images, making their exploitation difficult, if not impossible, in certain areas of the body. It is therefore crucial to provide solutions to mitigate the non-uniformity of the spins excitation. Failing this, these imaging systems with very high fields will not reach their full potential.For relevant high field clinical diagnosis, it is therefore necessary to create RF pulses homogenizing the excitation of all spins (here of the human brain), and optimized for each individual to be imaged. For this, an 8-channel parallel transmission system (pTX) was installed in our 7 Tesla scanner. While most clinical MRI systems only use a single transmission channel, the pTX extension allows to simultaneously playing various forms of RF pulses on all channels. The resulting sum of the interference must be optimized in order to reduce the non-uniformity typically seen.The objective of this thesis is to synthesize this type of tailored RF pulses, using parallel transmission. These pulses will have as an additional constraint the compliance with the international exposure limits for radiofrequency exposure, which induces a temperature rise in the tissue. In this sense, many electromagnetic and temperature simulations were carried out as an introduction of this thesis, in order to assess the relationship between the recommended RF exposure limits and the temperature rise actually predicted in tissues.This thesis focuses specifically on the design of all RF refocusing pulses used in non-selective MRI sequences based on the spin-echo. Initially, only one RF pulse was generated for a simple application: the reversal of spin dephasing in the transverse plane, as part of a classic spin echo sequence. In a second time, sequences with very long refocusing echo train applied to in vivo imaging are considered. In all cases, the mathematical operator acting on the magnetization, and not its final state as is done conventionally, is optimized. The gain in high field imaging is clearly visible, as the necessary mathematical operations (that is to say, the rotation of the spins) are performed with a much greater fidelity than with the methods of the state of the art. For this, the generation of RF pulses is combining a k-space-based spin excitation method, the kT-points, and an optimization algorithm, called Gradient Ascent Pulse Engineering (GRAPE), using optimal control.This design is relatively fast thanks to analytical calculations rather than finite difference methods. The inclusion of a large number of parameters requires the use of GPUs (Graphics Processing Units) to achieve computation times compatible with clinical examinations. This method of designing RF pulses has been experimentally validated successfully on the NeuroSpin 7 Tesla scanner, with a cohort of healthy volunteers. An imaging protocol was developed to assess the image quality improvement using these RF pulses compared to typically used non-optimized RF pulses. All methodological developments made during this thesis have contributed to improve the performance of ultra-high-field MRI in NeuroSpin, while increasing the number of MRI sequences compatible with parallel transmission

This thesis presents a 12-bit 80-MS/s low power pipelined successive approximation register (SAR) analog-to-digital converter (ADC) with loading-free architecture. The basic idea of this work is manipulating the capacitor array of the second-stage SAR ADC to serve as the feedback capacitor of the first stage amplifier during its amplification mode. In addition to the saving in the occupied area of the total capacitor, such an arrangement reduces the power consumption of the used high performance operation amplifier as well, resulting in a low-power and compact ADC. Additionally, the fixed-window function technique is adopted to cut the power consumption and tolerate non-idealities in the first-stage SAR ADC, including the comparator’s erroneous judgments incurred by incomplete settling behavior during the capacitor array switching, large INL/DNL errors due to the capacitor mismatch, and missing codes induced by comparator offset. Moreover, the direct switching technique is also utilized to reduce the critical path delay between the digital control logic and switching buffers. This proof-of-concept ADC is fabricated in TSMC standard low-power 90-nm 1P9M CMOS process with the active area of only 0.117 mm2. The measured peak SNDR is 55.98 dB and effective resolution bandwidth (ERBW) is 35 MHz. The total power consumption is 2.72 mW.

This delay locked loop uses TSMC 90nm process. It uses the shift-counting type successive approximation register to control the digital delay line, which can solve the problem of harmonic lock. The part of delay line uses a complementary way to improve the range of lockable and using coarse and fine way to improve the resolution of delay. This delay locked loop uses 10-bit successive approximation register to achieve the fast locking. In addition, the locking range is from 100 MHz to 1 GHz. The supply voltage is 1.2V. The delay resolution is about 4 ps. The power is 0.38 mW at 100 MHz and 0.9 mW at 1 GHz. The jitter is 8.8 ps at 100 MHz and 2.6 ps at 1 GHz. The lock time is 40 clock cycles at 100MHz and 24 clock cycles at1 GHz.

For 16-bit successive approximation register (SAR) analog-to-digital converters (ADCs), noise and linearity are two major challenges for chip implementation. In this work, without the oversampling and noise-shaping techniques, I use several circuit design skills to meet the noise specification. For the linearity, it’s mainly affected by the capacitor mismatch. In this thesis, two techniques are presented to improve the ADC linearity. One is the level-two capacitor-swapping technique, and the other is the fast-binary-window DAC switching scheme. For the first two MSB capacitor switching, the level-two capacitor-swapping utilizes the swapping mechanism to transform the distortion into noise for better SFDR. The fast-binary-window DAC switching technique changes the SAR ADC’s conventional switching method to improve SNDR by reducing unnecessary capacitor switching. A 16-bit 1-MS/s calibration-free SAR ADC was implemented in TSMC 0.18μm CMOS. This ADC chip occupies die area of 0.52 mm2. It consumes 1.54 mW from a 1.8V supply. At a 1-kHz input frequency, the measured DNL is -0.7/1.3 LSB. The measured INL is -3.1/3.3 LSB. The measured SNDR and SFDR are 76.3 dB and 102 dB, respectively. This leads to a Schreier FOM of 161.4 dB.

A single-channel 8-bit 400-MS/s successive-approximation register (SAR) analog-to-digital converter (ADC) in 90-nm CMOS process is presented in this thesis. We propose a hybrid architecture for high-speed SAR ADC without a complex calibration engine. The operation speed is enhanced by adopting the loop-unrolled technique in the coarse conversions. Considering the mismatch between coarse and fine conversions, we adopt the non-binary search scheme with redundancy to maintain the overall performance. Moreover, two circuit techniques are proposed to increase the operation speed in the fine conversions. Firstly, a pre-amplifier-only comparator is proposed to shorten the critical timing path in the fine conversions. It significantly reduces the comparator reset time. Secondly, we propose a high-gain dynamic pre-amplifier to mitigate the offset mismatches among the latches for the requirement of the overall accuracy. With the above-mentioned techniques, it leads to a calibration-free design. The proof-of-concept prototype was fabricated in a TSMC 90-nm CMOS technology. The core area occupies 0.0276 mm2. At a supply voltage of 1.2-V and sampling rate of 400-MS/s, the power consumption of the SAR ADC is 3.198 mW. The peak ENOB is 7.15 bits without complex calibration circuit. It achieves a figure of merit (FoM) of 56.29 fJ/conversion-step.
