use of efficient methods of weed control with as regards environmental sustainability as well as increased crop yield and also weed resistance to herbicides is essential. in order to, an experiment was conducted in 2012 in the damavand jaban in iran. experiment treatments were compared in a split plot design by a randomized completely block design with 3 replication. the used variety of maize w...

This work aims to design the uplink (UL) of a cellular network for maximal energy efficiency (EE). Each base station (BS) is randomly deployed within a given area and is equipped with M antennas to serve K user equipments (UEs). A multislope (distance-dependent) path loss model is considered and linear processing is used, under the assumption that channel state information (CSI) is acquired by ...

Analog–Digital (A/D) converters used in instrumentation and measurements often require high absolute accuracy, including very high linearity and negligible dc offset. The realization of high-resolution Nyquist-rate converters becomes very expensive when the resolution exceeds 16 bits. The conventional delta–sigma ( ) structures used in telecommunication and audio applications usually cannot sat...

In this paper, we will obtain first integral, integrating factor and λ-symmetry of third-order ODEs u ⃛=F(x,u,u ̇,u ̈). Also we compare Prelle -Singer (PS) method and λ-symmetry method for third-order differential equations.In this paper, we will obtain first integral, integrating factor and λ-symmetry of third-order ODEs u ⃛=F(x,u,u ̇,u ̈).

Integrating A/D converters have two characteristics in common. First, as the name implies, their output represents the integral or average of an input voltage over a fixed period of time. Compared with techniques which require that the input is “frozen” with a sample-and-hold, the integrating converter will give repeatable results in the presence of high frequency noise (relative to the measure...

In this paper, we investigate the impact of network densification on the performance in terms of downlink signalto-interference (SIR) coverage probability and network area spectral efficiency (ASE). A sophisticated bounded dual-slope path loss model and practical user equipment (UE) densities are incorporated in the analysis, which have never been jointly considered before. By using stochastic ...

The aim of this paper is the analytical solutions the family of rst-order nonlinear stochastic differentialequations. We dene an integrating factor for the large class of special nonlinear stochasticdierential equations. With multiply both sides with the integrating factor, we introduce a deterministicdierential equation. The results showed the accuracy of the present work.

Background: Teaching professional ethics in the ceramics branch requires using a standard system of integrating professional ethics components in the ceramics curriculum elements to determine the relationship between professional ethics and the curriculum components. The aim of the present study is a conceptual framework for integrating the elements of professional ethics in the ceramic’s curri...

saffron is one of the highly exotic spices known for traditional values and antiquity. it is used for home décor besides serving as a colorant flavor and is widely known for medicinal value. over the last few years, saffron has garnered a lot of interest due to its anti-cancer, anti-mutagenic, anti-oxidant and immunomodulatory properties. integration of systems biology approaches with wide appl...
