PV Module Energy Rating Standard IEC 61853-3 Intercomparison and Best Practice Guidelines for Implementation and Validation

The IEC 61853 standard series aims to provide a standardized measure for photovoltaic (PV) module energy rating, namely the Climate Specific Energy Rating(CSER). For this purpose, it defines procedures for the experimental determination of input data and algorithms for calculating the CSER. However, some steps leave room for interpretation...

Approximate confidence regions for the parameters of three software reliability models

Expressions are derived from which confidence regions for the parameters of three specific software reliability models can be computed. These expressions are based on the asymptotic probability distribution of the maximum likelihood estimator. Some numerical results of point estimates as well as confidence regions are given, based on simulated...

A model of the human decision maker observing a dynamic system

In this report a model of the human observer and decision maker is described. A submodel of the human observer is formulated in linear estimation theoretical terms including the perception of the displayed information of a linear process and the central information processing stage. The subsequent decision process is described in terms of...

An improved flat front model for a gas loaded variable conductance heat pipe

A uniaxial flat front--"theory is presented for a gas loaded variable conductance heat pipe. The theory takes into account the inertial effects of the moving vapour, which can grow large under certain circumstances, but neglects the axial heat conduction of the wall and wick. A limited number of numerical examples indicates excellent agreement...

The effect of visual information on the manual approach and landing

The visual scene is an important source of information for the manual approach and landing task. This study deals with the effect of this information in combination with basic display information on the manual approach performance. In this context, a pre-experimental theoretical analysis has been performed in terms of the optimal control model....

Theoretical investigation of the basic thermal performance of multilayer insulation blankets

The thermal performance of evacuated multilayer insulation blankets depends on three modes of energy transfer: radiation between the radiation shields, gas conduction m the residual interstitial gas and solid conduction via the contacting interfaces. The importance of the contributions of the three heat transfer modes depends on many parameters...
