it seems impossible to think of the persian art without mentioning the significant presence of gardens. they are present in miniature painting, architecture, and literature. one of the modern works of persian fiction in which gardens play a significant role is malakut (1961), a novella by the modern iranian fiction writer bahram sadeqi (1936-1984). the story of this novella begins in a “green g...

A printed dipole slot antenna for 2.4GHz RFID band and 5.2GHz WLAN band application is designed fabricated on FR4 substrate and measured using Agilent network analyzer. This antenna effectively covers both 2.4GHz and 5.2GHz bands. The return losses of the measured results are in agreement with simulated results, the measured S parameters and radiation pattern showed that the proposed design is ...

Abstract: An inset feed microstrip patch antenna is designed to increase the bandwidth and return loss. RT-Duriod with dielectric constant of 4.4 is used as a substrate for the proposed antenna. RT-Duriod is a having a lowest dielectric constant and can reduce the dielectric losses associated with microstrip patch antenna. This antenna is useful for 2.4 GHz frequency, which comes under ISM (Ind...

a complete procedure for the design of w-band low noise amplifier in mmic technology is presented. the design is based on a simultaneously power and noise matched technique. for implementing the method, scalable bilateral transistor model parameters should be first extracted. the model is also used for transmission line utilized in the amplifier circuit. in the presented method, input/output ma...

Contagious bovine pleuropneumonia (CBPP) is a disease that causes high morbidity and mortality losses to cattle. The financial implications of these losses are of great significance to cattle owners. Control of CBPP is therefore important as a way to salvage the losses and increase the incomes of cattle owners. This study estimated the economic cost of CBPP and the benefits of its control in tw...

In portfolio theory, it is well-known that the distributions of stock returns often have non-Gaussian characteristics. Therefore, we need non-symmetric distributions for modeling and accurate analysis of actuarial data. For this purpose and optimal portfolio selection, we use the Tail Mean-Variance (TMV) model, which focuses on the rare risks but high losses and usually happens in the tail of r...

The authors consider efficient methods of amortizing actuarial gains and losses in defined-benefit pension plans. In the context of a simple model where asset gains and losses emerge as a consequence of random (independent and identically distributed) rates of investment return, it has been shown that direct amortization of such gains and losses leads to more variable funding levels and contrib...

This paper presents the design and experimental results of a miniaturized monolithic 2.4/5.7 GHz concurrent dual-band low noise amplifier with cascade configuration using InGaP/GaAs HBT technology for the first time. The first stage of the LNA provides high gain and input matching simultaneously at both 2.4 GHz and 5.7 GHz bands. The output matching of the second stage is realized by shunt-shun...
