Comparison of Kernel equating methods under NEAT and NEC designs

open access: yesInternational Journal of Assessment Tools in Education, 2023
In this study, Kernel test equating methods were compared under NEAT and NEC designs. In NEAT design, Kernel post-stratification and chain equating methods taking into account optimal and large bandwidths were compared.

Sociotechnical Theory and NEC System Design [PDF]

open access: bronze, 2007
The term 'Sociotechnical' is much more than merely a buzzword, it is a set of theories and concepts that seek to jointly optimize the co-evolution of organizations and technology. In this paper we show how the specification of a set of basic sociotechnical principles (responsible autonomy, adaptability and meaningfulness of tasks) could help to create ...

Design and Validation of the GI-NEC Score to Prognosticate Overall Survival in Patients With High-Grade Gastrointestinal Neuroendocrine Carcinomas [PDF]

open access: bronzeJournal of the National Cancer Institute, 2017
Prognostic markers for risk stratification of patients with gastrointestinal high-grade neuroendocrine carcinomas (GI-NECs) are lacking; we designed and validated a prognostic score for overall survival (OS).Consecutive patients diagnosed in five neuroendocrine specialist European centers were included.

Design and Validation of Blast Non-propagation Wall for Multi-Compartmented Explosive Storage Structure of Capacity 5T NEC per Compartment

open access: diamondDefence Science Journal, 2018
Conventional magazines for hazard division 1.1 are constructed using bricks and reinforced cement concrete (RCC) for which storage inside quantity distance (SIQD) is 2.4 W1/3 m, where W is Net Explosive Content in kg. New composite called laced reinforced concrete (LRC) has been developed recently, for which SIQD has been reduced up to 0.5 W1/3 m.

An antenna design for PANSAT using NEC.

open access: closed, 1991
In this thesis the Numerical Electromagnetics Code (NEC) is used to design an omnidirectional antenna for the Petite Amateur Navy Satellite (PANSAT). The completed antenna design uses a tangential turnstile antenna to achieve a circularly polarized radiation pattern with predicted worst nulls of approximately -3.0 dBi.

Equality of admission tests using kernel equating under the non-equivalent groups with covariates design

open access: yesInternational Journal of Assessment Tools in Education, 2021
Educational assessment tests are designed to measure the same psychological constructs over extended periods of time. This feature is important considering that test results are often used in the selection process for admittance to university programs ...
