A time domain modeling and simulation tool for beam-cavity interactions in LER and HER rings at PEP II are presented. The motivation for this tool is to explore the stability margins and performance limits of PEP II RF systems at higher currents and upgraded RF configurations. It also serves as test bed for new control algorithms and can define the ultimate limits of the architecture. The time ...

an experiment was conducted as randomized complete block design with three replications and 14 fertilizer treatments in year 2014. the treatments were including the control, application of chemical fertilizers according the soil analysis, application of 15, 30 and 45 tons of municipal  waste compost per ha as simple and with 25, 50 and 75% of chemical fertilizers. the results revealed that the ...

Abstract As the energy transition accelerates and renewable technologies become cost-competitive with fossil fuels in many countries, availability of finance could a bottleneck. Integrated assessment models (IAMs) other macro-economic (MET) typically do not feature detailed financial markets sufficiently consider financing barriers opportunities for to carbon neutrality. While progress has been...

In this paper, we explore three different ways of developing T-Trefftz finite elements of quadrilateral as well as polygonal shapes. In all of these three approaches, in addition to assuming an inter-element compatible displacement field along the element boundary, an interior displacement field for each element is independently assumed as a linear combination of T-Trefftz trial functions. In a...

in order to the effects of macronutrients  and micronutrients on morphological traits and yields of rice, an examination as factorial in random complete block design and 3 replicate in galoogah region during the year of 2014 conducted. the treatments of nutrients were microelements, microelements, and the mixture of microelements, macro elements and control. the results showed the treatments ha...

In the current study, macro and microelement contents of oat grains were determined by Inductively Coupled Plasma Atomic Emission Spectrometry (ICP-AES). P contents of grains were found between 2428.72 mg/kg (Arslanbey) and 4557.25 mg/kg (TL10). While K contents of oat samples change between 3055.99 mg/kg (TL63) and 5621.12 mg/kg (TL8), Ca contents of oats ranged from 568.50 mg/kg (TL63) to...

Architectural limitations in many situations make it necessary for the RC shear walls to be extended in plan in different directions at a single location that makes them a 3D configuration. Analysis of such walls is very challenging. In this research about 450 cases of 3D shear walls are considered with different shapes and heights. L, T and H-shape walls are studied. They are nonlinearly analy...

Hygienic macro systems, such as Scheme’s, automatically rename variables to prevent unintentional variable capture—in short, they “just work.” Yet hygiene has never been formally presented as a specification rather than an algorithm. According to folklore, the definition of hygienic macro expansion hinges on the preservation of alphaequivalence. But the only known notion of alpha-equivalence fo...

in treating the subject of musical language, a persian musician would be intrinsically drawn to the structural similarities between the persian music and language. indeed persian music and language are extremely related in their metrics, intonations and structural phrases (syntax). although we will draw upon this relationship, our aim in this article is to present “music as a language,” consist...
