دریاچۀ مهارلو به لحاظ نزدیکی به کلانشهر شیراز نقش تعدیلکنندۀ رطوبتی و دمایی مهمی بر این شهر دارد. بروز خشکسالی طی دهههای اخیر و متعاقب آن کاهش سطح آب این دریاچه بر وضعیت رطوبتی و دمایی مناطق پیرامونی آن به ویژه شهر شیراز آثار نامطلوبی به همراه داشته است. در این پژوهش تغییرات خط ساحلی دریاچۀ مهارلو و تأثیر آن بر عناصر آب و هوایی به ویژه رطوبت هوا و دمای سطح زمین نواحی مجاور دریاچه مورد بررسی ...
In common GP approaches, the space of genotypes (search space) is identical to the space of phenotypes (solution space). Facts and theories from molecular biology suggest the introduction of non-identical genospaces and phenospaces, and a generic genotype-phenotype mapping (GPM) which maps unconstrained genotypes into syntactically correct phenotypes. Neutral variants come into eeect due to GPM...
Precise spatio-temporal measurements of rainfall during seasonal monsoons are critical for accurate hydrologic analyses in the tropical regions of Southeast Asia. The use of satellite precipitation data is technologically sound but requires downscaling to minimize inherent uncertainties. The uncertainties at a local climate regime that are essential to be resolved are rarely reported; consequen...
Capturing ammonia from anaerobically digested manure could simultaneously decrease the adverse effects of ammonia inhibition on biogas production, reduce reactive nitrogen (N) loss to the environment, and produce mineral N fertilizer as a by-product. In this study, gas permeable membranes (GPM) were used to capture ammonia from dairy manure and digestate by the diffusion of gaseous ammonia acro...
A relativistic quark model and a new set of wave functions of nucleon and ∆ have been used to study the electromagnetic properties of 12 + baryons and photoelectric production of ∆(1236). Theoretical results of GpM (q 2), μp, μΛ, μpG p E(q )/GpM (q 2), GE(q 2), and GM1+(q 2), μ, E1+, S1+ of p → ∆ are presented.
The observation of hydrological as well meteorological data is very essential for any kind hydraulic and study. In Nepal, due to the significant variation topography climatic characteristics it necessary establish stations densely, here only 231 are available handled by government organizations Department Hydrology Meteorology (DHM). Even though, many limitations, satellite useful water resourc...
Local dry/wet conditions are of great concern in regional water resource and floods/droughts disaster risk management. Satellite-based precipitation products have greatly improved their accuracy and applicability and are expected to offer an alternative to ground rain gauges data. This paper investigated the capability of Tropical Rainfall Measuring Mission (TRMM) rainfall data for monitoring t...
تبخیر و تعرق از مؤلفههای اصلی بیلان آب هر منطقه و از عوامل کلیدی برای برنامهریزی صحیح و مناسب به منظور بهبود بازده آب مصرفی در اراضی فاریاب است. تصاویر ماهوارهای به دلیل پوشش مناطق وسیع، به منظور غلبه بر محدودیتهای مکانی روشهای نقطهای، کاربرد بهتری برای مطالعات ناحیهای نسبت به دادههای ایستگاههای هواشناسی دارند. بنابراین، هدف از تحقیق حاضر برآورد تبخیر و تعرق واقعی حوضۀ آبریز دریاچۀ ارو...
We describe a major update of our Matlab freeware GloptiPoly for parsing generalized problems of moments and solving them numerically with semidefinite programming. 1 What is GloptiPoly ? Gloptipoly 3 is intended to solve, or at least approximate, the Generalized Problem of Moments (GPM), an infinite-dimensional optimization problem which can be viewed as an extension of the classical problem o...
