5 In groundwater modeling, Monte Carlo Markov Chain (MCMC) simulations are often used to calibrate aquifer parameters and propagate the uncertainty to the quantity of interest (e.g., pollutant concentration). However, this approach requires a large number of flow simulations and incurs high computational cost, which prevents a systematic evaluation of the uncertainty in presence of complex phys...
We argue that ‘topics’ of topic models can be used as a useful proxy for frames if (1) are operationalized connections between concepts; (2) theme-specific data used; and (3) topics validated in terms frame analysis. Demonstrating this, we analyse 12 climate change by NGOs, governments experts Indian US media, gathered modeling. contribute methodologically to modeling the social sciences analys...
Arabia considers Iran the main source of instability in the region and believes that Iran seeks to dominate the Sunni Arabs through creating Shiite crescent. Especially after the Islamic Revolution, two countries have been as the rivals in the Persian Gulf. Ideological competition is considered as the core of competition in the areas of geopolitics, geostrategics and geoeconomics. In recent yea...
Reconstructing the spatial pattern of a climate process through time from incomplete instrumental and climate proxy time series is a problem with clear societal relevance that poses both scientific and statistical challenges. The scope of these challenges, along with the interdisciplinary nature of the reconstruction problem, point to the need for greater cooperation between the earth science a...
بیمه گران همیشه بابت خسارات بیمه نامه های تحت پوشش خود نگران بوده و روش هایی را جستجو می کنند که بتوانند داده های خسارات گذشته را با هدف اتخاذ یک تصمیم بهینه مدل بندی نمایند. در این پژوهش توزیع های فیزتایپ در مدل بندی داده های خسارات معرفی شده که شامل استنباط آماری مربوطه و استفاده از الگوریتم em در برآورد پارامترهای توزیع است. در پایان امکان استفاده از این توزیع در مدل بندی داده های گروه بندی ...
We perform regression modeling to obtain estimates of the number of cycles (used as a proxy for application performance). A linear regression is performed in which the response (number of cycles) is a weighted sum of predictor variables (such as L1P misses, AXU instructions, XU instructions, FP operations, etc.) plus some random noise. Since linear relationships may not always be adequate to mo...
Genomic imprinting is a violation of Mendel's laws that enables selection to act on genes, depending on parent of origin, but, even more controversially, on the sex of the offspring. This study tested whether there are parent-of-origin effects on the heritability of empathy and systemizing in the general population as part of a larger question concerning the role of imprinted genes in the evolu...
