This paper presents some of the results of the simulation in the radiation section of an industrial boiler using an advanced mathematical model. Calculations are described for the flow, heat transfer, and chemical reaction processes occurring within a gas-fired cylindrical furnace. The calculation procedure is a two dimensional one in which the main hydrodynamic variables are the velocity and s...

The current study focuses on the challenges and threats faced by Indian consumer while using digital money. highlights buying patter of context conventional system. Methods: In theoretical model constructed reviewing different journals based as well evaluates factor effecting purchase decision light...

This study examines how the timing of waste disposal fee collection affects producer’s choice built-in product durability and social welfare in a durable-goods monopoly model. We categorize policies into two: advance (ADF) policy (DF) policy. show that DF has two opposing effects on durability. Firstly, gives producer an incentive to increase order delay households’ discount future payments (th...

Cooperative transmission by base stations (BSs) can significantly improve the spectral efficiency of multiuser, multicell, multiple input multiple output (MIMO) systems. We show that contrary to what is often assumed in the literature, the multiuser interference in such systems is fundamentally asynchronous. Intuitively, perfect timing-advance mechanisms can be best only ensure that the desired...

this study investigated 1) whether the effect of teacher-developed graphic organizers vis-à-vis student-developed ones was more significant on improving intermediate efl learners’ writing, and 2)whether the use of both graphic organizers had any impact on their writing. the participants were selectedin two stages: 130 students sat for a piloted proficiency test. those who scored above half ofth...

How does agricultural insurance affect the modernization of farming in low income countries? We focus on institutional contexts without formal contract enforcement, where smallholders cannot access modern inputs via markets. Instead, farmers can engage relational contracting with traders to sell their crop and gain (as an advance in-kind payment). Although conventional theory assumes that “crow...
