Data on the positive synergic action of dimethylacetamide and trehalose on quality of cryopreserved chicken sperm
No full textAbstractThis data article contains supporting information regarding the research article entitled “Combined effect of permeant and non-permeant cryoprotectants on the quality of frozen/thawed chicken sperm”(Mosca et. al., 2016) [1]. The combined effect of the permeant cryoprotectants agent dimethylacetamide and the non-permeant cryoprotectants agent trehalose on the quality of frozen-thawed chicken semen was assessed. In particular, the quantitative dimethylacetamide/trehalose ratio was investigated freezing semen samples according to the following treatments: trehalose 0.1M+0% dimethylacetamide (DMA-0), trehalose 0.1M+3% dimethylacetamide (DMA-3), trehalose 0.1M+6% dimethylacetamide (DMA-6)
Tão dúbio, tão coerente: forma e conteúdo nas crônicas jornalísticas de Sayed Kashua
No full textEste artigo consiste na análise de duas crônicas jornalísticas do escritor árabe-israelense Sayed Kashua publicadas no jornal israelense Haaretz. Estes textos são selecionados devido à sua riqueza de conteúdo e pelo uso de estratégias retóricas, tais como a autoironia e o sarcasmo, para expor os conflitos pelos quais passa o “eu do cronista” retratado pelo autor. Este estudo tem como base os Estudos Culturais e os Novos Paradigmas Literários, ferramentas que permitem o estudo das crônicas jornalísticas como textos literários. Nestas crônicas, de uma maneira despretensiosa, partindo de experiências subjetivas e de temas familiares, com autoironia e tom satírico, Kashua reporta as experiências de um árabe israelense que vive num embate em torno de suas duplas lealdades e ideologias conflitantes, refletindo uma negociação entre sua etnicidade e sua nacionalidade. A crônica, neste contexto, é considerada o local apropriado para a escrita de Kashua: a ambiguidade do gênero é similar à necessidade de quebras de dualidades na sociedade israelense para entendermos e convivermos com o “eu do cronista” de Sayed Kashua. So dubious, so coherent: form and content in Sayed Kashua´s journalistic chronicles - Abstract: This paper consists of the literary analysis oftwo journalistic chronicles written in Hebrew by the Muslim Arab Israeli author Sayed Kashua published in the Israeli newspaper Haaretz. These texts are selected due to their richness of content and use of rhetorical strategies such as self-irony and sarcasm to expose the conflicts through which the “I of the chronicler” portrayed by the author goesthrough. This analysis will rely on theoretical assumptions of Cultural Studies and the “New literary paradigms”, tools that will enable us to study the journalistic chronicle as a literary text. In these chronicles, in a non-pretentious way, coming from the subjective experiences and family topics, with self-irony and in a satirical way, Kashua reports the experiences of an Israeli Arab who lives in a clash over his dual loyalty and conflicting ideologies, reflecting a negotiation between his ethnicity and his nationality. The chronicle, in this context, is considered the appropriate location for Kashua’s writings: the ambiguity of the literary genre is similar to the necessity of breaking dualities in Israeli society to understand and to be acquainted with the “I of the chronicler” of Sayed Kashua
Distributed chance-constrained model predictive control for condition-based maintenance planning for railway infrastructures
No full textWe develop a Model Predictive Control (MPC) approach for condition-based maintenance planning under uncertainty for railway infrastructure systems composed of multiple components. Piecewise-affine models with uncertain parameters are used to capture both the nonlinearity and uncertainties in the deterioration process. To keep a balance between robustness and optimality, we formulate the MPC optimization problem as a chance-constrained problem, which ensures that the constraints, e.g., bounds on the degradation level, are satisfied with a given probabilistic guarantee. Two distributed algorithms, one based on Dantzig-Wolfe decomposition and the other derived from a constraint-tightening technique, are proposed to improve the scalability of the MPC approach. Computational experiments show that the distributed method based on Dantzig-Wolfe decomposition performs the best in terms of computational time and convergence to global optimality. By comparing the chance-constrained MPC approaches with deterministic approach, and traditional time-based maintenance approach, we show that despite their high computational requirements, chance-constrained MPC approaches are cost-efficient and robust in the presence of uncertainties.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Team Bart De SchutterRailway EngineeringDelft Center for Systems and Contro
Hardware Implementation of a 2D Chaotic Map-Based Audio Encryption System Using S-Box
No full textThis paper presents a hardware-based audio encryption system using a 2D chaotic map and dynamic S-box design implemented on an Artix-7 FPGA platform. Three distinct chaotic maps—logistic–fraction (2D-LF), logistic–sine (2D-LS), and fraction–sine (2D-FS)—were investigated and implemented on an FPGA. The 2D-LF map was employed in the encryption system for its throughput and power efficiency performance. The proposed encryption system benefits from the randomness of chaotic sequences for block permutation and S-box substitution to enhance the diffusion and confusion properties of the encrypted speech signal. The system’s encryption strength is validated through performance evaluations, using the mean squared error (MSE), signal-to-noise ratio (SNR), correlation coefficients, and NIST randomness tests, which confirm the unpredictability of the encrypted speech signal. The hardware implementation results show a throughput of 2880 Mbps and power consumption of 0.13 W
The Pherobase
No full textThe Pherobase was developed by Dr. Ashraf El-Sayed, a research scientist at HortResearch in New Zealand, with the primary objective of providing "coverage of the literature published on chemical communication in insects." The Pherobase is intended for use by both scientific and non-scientific communities and currently contains "over 10000 entries, around 3000 molecules, and over 32000 static html pages that make it the world's largest database of behavior modifying chemicals." The site contains multiple Insect indices for such categories as Order, Family A-Z, and Species; References indices such as Discovery by Author, Discovery by Year, and References A-Z; and indices for Compounds, Compounds by Family, and Compounds by Genus. The site also contains a Contribution Form, and number of online forums relating to The Pherobase
