The core loss calculation is important for the design and performance evaluation of high-frequency transformers. It related to dimensions, temperature rises performance, operating efficiency transformer designs. Some scholars have examined correlation between characteristics losses, such as air gap length structure; some investigations also analyzed effects harmonics, distortion flux, other fac...

In this paper, we introduce non-interest profit/loss sharing (PLS) banks into a three-period overlapping generations model. Two types, (low- and high quality) investments are assumed and capital accumulation and level of output in the steady state is considered. Then, administrative rationing is introduced to the model. It is shown that the level of capital accumulation and output in equilibriu...

androgenetic alopecia is the most common form of hair loss in men. the present study was designed to evaluate the hair growth-promoting activity of a preparation of the adiantum capillus veneris linn. (a. capillus veneris linn.) on albino mice using a testosterone-induced alopecia model. five groups of albino mice were studied: (a) testosterone solution only (n=6); (b) testosterone ‏+ finasteri...

parameters as interception, infiltration, water storage on surface holes and soil profile, evapotranspiration are factors of loss water in a watershed and avoid from changing of precipitation to runoff. in this study, by use of hec-hms model and comparison of results of different methods of precipitation loss evaluation (initial and constant, green & ampt, scs curve number, deficit & constant a...

The purpose of this paper is to study the suitability of loan loss provision (LLP) of Iranian banks when the industry is dealing with earning management behaviors. This goal has been reached using a two-step approach to analyze the discretionary component of LLP and then examine the relevant factors. This empirical study uses an unbalanced panel data of 15 listed banks during the 2006-2017 peri...

Degradation is a common problem for polymer matrix composites (PMCs) under low thermal cycling conditions. This paper investigates the effects of low thermal cycling on total mass loss (TML) and surface degradation of PMCs. Unnotched and open-hole specimens were weighed before and after low thermal cycling. The total mass loss and surface degradation of the specimens were studied over 250 cycle...

Loss-averse behavior makes the newsvendors avoid the losses more than seeking the probable gains as the losses have more psychological impact on the newsvendor than the gains. In economics and decision theory, the classical newsvendor models treat losses and gains equally likely, by disregarding the expected utility when the newsvendor is loss-averse. Moreover, the use of unbounded utility to m...

In most production-inventory systems, the products are transferred from the production centre to the inventory (warehouse) in subbatchs rather than one at a time. In this paper, mathematical models of such systems for both deterministic and stochastic cases of demand are developed and analysed. Comparison of these new models with the EBQ model shows a considerable loss when applying the ru...
