يهدف هذا العمل إلى تفسير و تحليل الطاقة الفائقة التي تمتلكها بعض الجسيمات الكونية التي تصل الأرض، و ذلك باستخدام فرضية التزايد المكمم لسرعة الضوء في الزمن الماضي السحيق، تأسيساً على قانون انحفاظ الطاقة ، و آلية التحول المتبادل بين الحالة الجسيمية و الحالة الموجية، و أخذ جسيم النيوترون مثال للدراسة.
This work aims to explane and analysise some cosmic particles that reach to the earth with super high energy using the hypothesis of increasing the speed of light dated to ancient past time ,based on the energy conservation law and the mechanism of transformation between particle state and wave state.As example ,the speed of neutrin has been taken for studying.

Developers of text generation models rely on automated evaluation metrics as a stand-in for slow and expensive manual evaluations. However, image captioning metrics have struggled to give accurate learned estimates of the semantic and pragmatic succe
ss of output text. We address this weakness by introducing the first discourse-aware learned generation metric for evaluating image descriptions. Our approach is inspired by computational theories of discourse for capturing information goals using coherence. We present a dataset of image--description pairs annotated with coherence relations. We then train a coherence-aware metric on a subset of the Conceptual Captions dataset and measure its effectiveness---its ability to predict human ratings of output captions---on a test set composed of out-of-domain images. We demonstrate a higher Kendall Correlation Coefficient for our proposed metric with the human judgments for the results of a number of state-of-the-art coherence-aware caption generation models when compared to several other metrics including recently proposed learned metrics such as BLEURT and BERTScore.
The main goal of the presented research in this paper is to find a general way to solve longitudinal vibration problems. This way must solve these problems in nonlinear elastic bar systems with a biological factor.
We applied longitudinal vibration
equations in a nonlinear elastic bar with biological factor, the bar material was taken non-linear. and solve the problem in a bar of finite length.
The aim of this research is measure of airborne PM10 and
PM2.5 concentrations in different locations in Homs during the
seasons of the year, finding the relationship between PM2.5 and
PM10 .
A portable GRIMM aerosol dust monitor & counter was use
d,
the measurements were conducted in twenty different locations in
city Homs in the morning, noon, and evening periods during the
seasons of the year.
In this study, an Interaction Function between quasi particles has been introduced
into an energy formula in Kinetic Equation of Quantum Plasmas. Such new type can be
used to study quasi Particles of Quantum Fermi Plasmas, since it contains quantum
term
that is correlated with Bohm Potential, when the mean inter-particle distance is of the same
order as the de-Broglie thermal wavelength. An interaction function between quasi
particles has been expressed using spherical Functions in three-dimensional space with
Landau’s spread coefficients for ℓ = 0 , 1 , 2 . Using such representation led to obtaining
the dispersion relation of the structural waves and its energy Spectrum in balanced local
condition. The use of Landau parameters in this study isconsidered new comparing to other
studies in this field. It allows us to get more generic and more precise dispersion relations
with new previously unknown spectrum energy in Quantum Fermi Plasmas.
The contribution of relative light particles and relative neutrinos in the cosmic
Omega-density parameter (W) was separately calculated based on the data of Wilkinson
Microwave Anisotropy Probe. Also it has been shown that the effect of the relativ
e
particles circulating in the universe in Omega-density parameter is roughly equivalent to
the effect of the Big Bang neutrinos in this parameter and the universe will remain in the
vicinity of the critical situation.
