In the past, various virtual Frisch-grid designs have been proposed for cadmium zinc telluride (CZT) and other compound semiconductor detectors. These include three-terminal, semi-spherical, CAPture, Frisch-ring, capacitive Frisch-grid and pixel devices (along with their modifications). Among them, the Frisch-grid design employing a noncontacting ring extended over the entire side surfaces of p...

New data regarding performance studies of Frisch-grid CdZnTe (CZT) detectors are presented. The Frisch-grid detector configuration under investigation is a bar shaped CZT crystal with the side surfaces coated with an insulating layer. A Frisch grid is fashioned by inserting the CZT bar into a metallic sleeve, or by depositing the metal directly upon the insulator; hence the semiconductor materi...

This article is a “theme” review of three books written by management theorists of high repute. (It follows in the footsteps of a piece published here 4 years ago [Frisch, 1995].) These authors approach management from very different perspectives. But to quote Frisch, “Unfortunately, every con-ceptualization and interpretation needed to arrive at a theory represents the point of view or, more g...

This is an adapatation by U. Frisch of an English translation by Thomas E. Burton of Euler’s memoir ‘Principes généraux du mouvement des fluides’ (Euler, 1775b). Burton’s translation appeared in Fluid Dynamics 34 (1999) pp. 801–82, Springer and is here adapted by permission. A detailed presentation of Euler’s published work can be found in Truesdell, 1954. Euler’s work is discussed also in the ...

On the Identification of Frisch Labor Supplies This paper examines how Frisch labor supplies, and other structural components of the intertemporal model of labor supply, can be recovered from estimates obtained with the approach developed by Heckman and MaCurdy. JEL Classification: J22

Trygve Haavelmo got the Nobel prize in economics (the prize in memory of Alfred Nobel) in 1989 – essentially for his 1944 treatise: “The probability approach to econometrics”, where econometrics eventually was founded on probability and mathematical statistics and where simultaneous equation models were introduced. Haavelmo learned statistics from Frisch, and was influenced by Neyman. Ragnar Fr...

The paper presents a general framework for the Frisch scheme and the extended compensated least squares technique within which two new algorithms for the identification of single-input single-output linear time-invariant errors-in-variables models are proposed. The first algorithm is essentially the Frisch scheme using a novel model selection criterion. The second method is a modification of th...
