this study seeks to examine how a company can select the best intermediary for its marketing channels with minimum of criteria and time. a theoretical framework is proposed based on the most important tasks of intermediary and the criteria to measure them. there are four basic tasks and thirty criteria in three independent levels. subsequently, an exploratory case study in iranian food industry...

The paper presents a new two-dimensional computational approach and results for laminar/laminar internal condensing flows. Accurate numerical solutions of the full governing equations are presented for steady and unsteady film condensation flows on a sidewall inside a vertical channel. It is found that exit conditions and noise sensitivity are important. Even for stable steady solutions obtaine...

The photodissociation of DNCN following excitation of the C 2A"<--X 2A" electronic transition was studied using fast beam photofragment translational spectroscopy. Analysis of the time-of-flight distributions reveals a photodissociation channel leading to D+NCN competitive with the previously observed CD+N2 product channel. The translational energy distributions describing the D+NCN channel are...

In this contribution a new procedure for parameter identification for the material characterisation of rubber blends is proposed which is based on genetic algorithms. Such a model has to consider the effect of wall slippage on the viscous properties as well as the identification of a new material parameter regarding die swell. As basis serves an experimental investigation of the viscous propert...

By molecular dynamics simulations, the molecular mechanism of the channel currents is becoming clear. However, the quantitative link between molecular mechanism and action pote...

In the last years, CDMA has been established as a standard multiple access scheme in mobile radio communications. However, high spectral efficiency can only be achieved by applying multi-user detection schemes combatting the inherent multi-user interference. Since the optimum maximum likelihood approach is far to complex for practical implementations, suboptimum iterative strategies are applied...

In this paper, we propose a method for analysis of linear turbo equalization based on extrinsic information transfer (EXIT) charts. Given channel knowledge and therefore the optimum linear equalizer coefficients, evolution of soft information of the soft-input soft-output (SISO) equalizer can be estimated via computing bit error rates (BER) analytically. Compared to conventional analysis method...

A single microfluidic chip consisting of six microfluidic flow-focusing devices operating in parallel was developed to investigate the feasibility of scaling microfluidic droplet generation up to production rates of hundreds of milliliters per hour. The design utilizes a single inlet channel for both the dispersed aqueous phase and the continuous oil phase from which the fluids were distributed...

Laser-induced fluorescence velocimetry measurements obtained from the interior of a 6-kW Hall thruster using the Xe I 6s 3=2 02 ! 6p 3=2 2 transition at 823.4 nm (vacuum) and the Xe I 6s0 1=2 01 ! 6p0 3=2 2 transition at 834.9 nm (vacuum) are presented. The thruster is operated under seven conditions, with discharge voltages ranging from 150 to 600 V and anode mass flow rates ranging from 10 to...

In this paper, we consider orthogonal multiple access coded schemes with correlated sources. The sources are distributedly encoded and their correlation is exploited at the access point (AP). In particular, we assume that each source uses a classical channel code to transmit, through an additive white Gaussian noise (AWGN) channel, its information to the AP. Here component decoders, associated ...
