For energy experts the oil sources in the world except from Middle East end Khazar zone will be exhausted in the next 15 years. In this situation being dependent to outside by oil means that political,economical and ecological problems which focuses on energy’ll be the determinative component for world’s future. Most of the countries are looking out new ways for renewable energy sources like solar, geothermal, hydrogen, heave, biodiesel, wind energy. Between these alternatives wind energy and biodiesel are the most promising ones.The process of the energy problems and transforming them into oppotunities is valid for Turkey too. The aim of the study is to show the the problems due to the heavy usage of fossil fuel, and try to find out how these problems can be transformed into oppurtunities while using renewable energy sources general for world in special for Turkey.energy, Turkey, renewable energy
Generalized von Neumann–Kakutani transformation and random-start scrambled Halton sequences
AbstractIt is a well-known fact that the Halton sequence exhibits poor uniformity in high dimensions. Starting with Braaten and Weller in 1979, several researchers introduced permutations to scramble the digits of the van der Corput sequences that make up the Halton sequence, in order to improve the uniformity of the Halton sequence. These sequences are called scrambled Halton, or generalized Halton sequences. Another significant result on the Halton sequence was the fact that it could be represented as the orbit of the von Neumann–Kakutani transformation, as observed by Lambert in 1982. In this paper, I will show that a scrambled Halton sequence can be represented as the orbit of an appropriately generalized von Neumann–Kakutani transformation. A practical implication of this result is that it gives a new family of randomized quasi-Monte Carlo sequences: random-start scrambled Halton sequences. This work generalizes random-start Halton sequences of Wang and Hickernell. Numerical results show that random-start scrambled Halton sequences can improve on the sample variance of random-start Halton sequences by factors as high as 7000
Derivative-based Shapley value for global sensitivity analysis and machine learning explainability
We introduce a new Shapley value approach for global sensitivity analysis and
machine learning explainability. The method is based on the first-order partial
derivatives of the underlying function. The computational complexity of the
method is linear in dimension (number of features), as opposed to the
exponential complexity of other Shapley value approaches in the literature.
Examples from global sensitivity analysis and machine learning are used to
compare the method numerically with activity scores, SHAP, and KernelSHAP
Por Que Dizem “Adiós”: Uma Compreensão Crítica Da Economia Política Da Migração Contemporânea De Venezuelanos
The aim of this study is to create a pattern by looking at the historical background of the migration movement in Venezuela and to reveal that the Venezuelan diaspora is a social movement that takes place with push factors, based on the push and pull theory. In this context, it has been focused on the economic and political background of the Venezuelan migration movement, and by looking at the political economy history, it has been determined that the migration movement took place in three different waves. By analyzing the push factors, the development of the migration phenomenon in Venezuela was followed and a framework was drawn with the sociological contexts of the target countries. The main argument of the article is the claim that the current Venezuelan migration movement took place with push factors, considering the economic and political conditions, while the first two migration waves were depending on the pull factors.El objetivo de este estudio es crear un patrón al observar los antecedentes históricos del movimiento migratorio en Venezuela y revelar que la diáspora venezolana es un movimiento social que se lleva a cabo con factores de empuje, basados en la teoría de empujar y tirar. En este contexto, se ha centrado en los antecedentes económicos y políticos del movimiento migratorio venezolano y, al observar la historia de la economía política, se ha determinado que el movimiento migratorio se dio en tres oleadas diferentes. Mediante el análisis de los factores de empuje, se siguió el desarrollo del fenómeno migratorio en Venezuela y se trazó un marco con los contextos sociológicos de los países objetivo. El argumento principal del artículo es la afirmación de que el movimiento migratorio venezolano actual se dio con factores de empuje, considerando las condiciones económicas y políticas, mientras que las dos primeras olas migratorias dependieron de los factores de atracción.O objetivo deste estudo é criar um padrão olhando para o contexto histórico do movimento migratório na Venezuela e revelar que a diáspora venezuelana é um movimento social que ocorre com fatores push, com base na teoria push and pull. Nesse contexto, concentrou-se no contexto econômico e político do movimento migratório venezuelano e, analisando a história da economia política, determinou-se que o movimento migratório ocorreu em três ondas diferentes. Ao analisar os fatores de impulso, acompanhou-se o desenvolvimento do fenômeno migratório na Venezuela e traçou-se um quadro com os contextos sociológicos dos países-alvo. O principal argumento do artigo é a afirmação de que o atual movimento migratório venezuelano ocorreu com fatores de impulso, considerando as condições econômicas e políticas, enquanto as duas primeiras ondas migratórias foram dependentes dos fatores de atração
Diffusion of myosin V on microtubules
Organelle transport in eukaryotes employs both microtubule and actin tracks to deliver cargo effectively to their destinations, but the question of how the two systems cooperate is still largely unanswered. Recently, in vitro studies revealed that the actin-based processive motor myosin V also binds to, and diffuses along microtubules. This biophysical trick enables cells to exploit both tracks for the same transport process without switching motors. The detailed mechanisms underlying this behavior remain to be solved. By means of single molecule Total Internal Reflection Microscopy (TIRFM), we show here that electrostatic tethering between the positively charged loop 2 and the negatively charged C-terminal E-hooks of microtubules is dispensable. Furthermore, our data indicate that in addition to charge-charge interactions, other interaction forces such as non-ionic attraction might account for myosin V diffusion. These findings provide evidence for a novel way of myosin tethering to microtubules that does not interfere with other E-hook-dependent processes
Strong Localizations of the Kobayashi Distance
Recently, visibility property of Kobayashi (almost) geodesics has been used
to provide localizations of the Kobayashi distance. In this note, we provide
sufficient growth conditions for Kobayashi distance to obtain new strong
multiplicative and additive localization results. Curiously, the conditions we
provide are deeply related to the behaviour of the Kobayashi geodesics

Precise estimates of invariant distances on strongly pseudoconvex domains
Studying the behavior of real and complex geodesics we provide sharp
estimates for the Kobayashi distance, the Lempert function, and the
Carath\'eodory distance on -smooth strongly
pseudoconvex domains. Similar estimates are also provided for the Bergman
distance on strongly pseudoconvex domains with -boundary
