Chipping Away at the First Amendment: Newspapermen Must Disclose Sources

This Comment will explore the background and history of the journalistic privilege in light of case law and early constitutional argument. It will analyze the recent Supreme Court decisions denying a privilege to newsmen to conceal their sources, and attempt to explain how this privilege can best be maintained

The Compulsory School Attendance Case: Wisconsin v. Yoder

It is an important constitutional doctrine that a law generally constitutional on its face, may be unconstitutional as applied in specific instances. The Amish case marks the first occasion that the Court has clearly articulated that exception in favor of a minority religious group. It would appear that compulsory education laws are- on their face --within a state\u27s constitutional powers, but under the facts of this case, the First Amendment requires that the Amish be exempt

Português controlado para a tradução automática : Português-Italiano

Neste trabalho propõe-se um fragmento de português controlado para a Tradução Automática. A linguagem controlada proposta é do tipo Machine-oriented Controlled Language (MOCL), ou seja, orientada para a máquina, em concreto, para a redação de textos a serem traduzidos por um sistema de tradução automática. Em termos de cobertura lexical, este fragmento não se destina a um domínio específico, pelo que, dado o seu carácter geral, pode ser utilizado para escrever textos diversos. O português controlado para a tradução automática para italiano proposto neste trabalho tem como objetivo a simplificação das estruturas dos textos de partida que causam problemas de tradução automática e, consequentemente, a eliminação, das ambiguidades, entre outros aspetos indutores de maus resultados, para se obter um output gramatical. Discute-se também uma “alternativa” à aplicação da linguagem controlada utilizando uma ferramenta disponibilizada pelo sistema de tradução automática SYSTRANet, demostrando-se que é possível resolver alguns problemas de tradução através da aplicação do português controlado e do auxílio de tal ferramenta. Por outras palavras, este fragmento de português controlado permite a redação controlada de textos cuja tradução produzirá resultados satisfatórios no que respeita aos fenómenos cobertos pelas regras apresentadas.In this study we propose a fragment of controlled Portuguese for machine translation into Italian. The Controlled Language here proposed is a Machineoriented Controlled Language (MOCL) and can be used to write texts that are destined to Machine Translation. This fragment, because of its peculiarities, is not created to cover a specific technical area but, instead, to write and than translate texts that belong to different areas. The scope of controlled Portuguese for machine translation into Italian here proposed is to simplify the structures of the source text which cause translation problems and, consequently, to eliminate ambiguities in order to obtain an acceptable output. In addition, we also discuss an “alternative” to the “traditional” controlled language, by using a tool offered by the machine translation system SYSTRANet. We demonstrated that is possible to resolve some of the translation problems analysed by using the controlled Portuguese and this translation tool. In other words, the fragment of controlled Portuguese here proposed allows the writing and the translation of texts written in this controlled language, so that the resulting translation is acceptable and "correct" because it follows the rules here presented

Dataset on broadband electrochemical impedance spectroscopy of Lithium-Ion batteries for different values of the state-of-charge

This dataset consists of electrochemical impedance spectroscopy measurements on commonly-used batteries, namely Samsung ICR18650-26J cylindrical Lithium-Ion cells. The complex impedance of the batteries was measured at a set of fourteen different frequencies from 0.05 Hz to 1000 Hz, using a random-phase multi-sine excitation signal. For each excited frequency, the current amplitude was 50 mA, resulting in a measurement uncertainty of approximately 0.1 mΩ. Six measurement repetitions are provided at ten different states-of-charge of four different brand-new batteries. Repeated EIS measurement results were obtained, for each individual battery cell, from six separate discharge cycles. All measurements were performed with the battery placed in a temperature-controlled chamber at 25 ± 1 °C. Batteries were allowed to thermalize before each measurement

Gesture recognition of sign language alphabet with a convolutional neural network using a magnetic positioning system

Gesture recognition is a fundamental step to enable efficient communication for the deaf through the automated translation of sign language. This work proposes the usage of a high-precision magnetic positioning system for 3D positioning and orientation tracking of the fingers and hands palm. The gesture is reconstructed by the MagIK (magnetic and inverse kinematics) method and then processed by a deep learning gesture classification model trained to recognize the gestures associated with the sign language alphabet. Results confirm the limits of vision-based systems and show that the proposed method based on hand skeleton reconstruction has good generalization properties. The proposed system, which combines sensor-based gesture acquisition and deep learning techniques for gesture recognition, provides a 100% classification accuracy, signer independent, after a few hours of training using transfer learning technique on well-known ResNet CNN architecture. The proposed classification model training method can be applied to other sensor-based gesture tracking systems and other applications, regardless of the specific data acquisition technology.</p

Tensor Renormalization Group: Studio del Modello di Ising

Questo lavoro fornisce un'analisi approfondita delle tecniche Tensor Renormalization Group (TRG) e High Order Tensor Renormalization Group (HOTRG) applicate allo studio di sistemi classici su reticolo, in particolar modo, alla transizione di fase continua nel modello di Ising bidimensionale. Le tecniche TRG costituiscono un metodo efficiente per la contrazione dei tensori di trasferimento. Questo approccio consente di gestire il costo computazionale, che altrimenti aumenterebbe in maniera esponenziale. Il lavoro comprende il calcolo di osservabili, come il cumulante di Binder e il calore specifico, mediante l'utilizzo dei tensori difetto. Inoltre, dalla matrice di trasferimento colonna a colonna, viene estratta la lunghezza di correlazione. L'analisi include l'applicazione di risultati della conformal field theory (CFT) per stimare gli autovalori del gruppo di rinormalizzazione e la carica centrale del sistema. Attraverso l'impiego del path integral, viene valutata l'entropia di entanglement del sistema quantistico equivalente, insieme allo spettro della matrice densità ridotta associata. I risultati ottenuti vengono confrontati con risultati esatti e stime Monte Carlo, evidenziando le potenzialità e i limiti di queste tecniche nel contesto dei modelli statistici su reticolo
