The Force Concept Inventory (FCI) can be used as an assessment tool to measure conceptual gains in a cohort of students. FCI uses conceptions/"misconceptions" lens rather than context dependent perspective, such "knowledge-in-pieces". In this study it was given first year students ($N=256$ students) pre- and post-mechanics lectures, at the University Johannesburg. From these results we examine ...

The power spectra for the daily Dow Jones average, both the original series and the de-trended series, are calculated. The spectra are of the form 1/ fCi with a close to 2 instead of 1. Also studied is the distribution of daily price changes which is in-between an exponential and a power law function. With certain criterion, this result suggests that stock market activities may not be qualified...

Today the world is changing with-changing business environment .To keep a pace with this one has to go through physical, mental, emotional and social stress. It become important for an individual organization them free from For purpose different kind of stress coping strategies are available. A comparative analysis was conducted on FCI CWC organaisation test approaches used by personality type....

We present a method for the direct generation of the lists of Ž . strings, suited for integral-driven full-CI FCI algorithms. This method generates the string lists each time they are used, and hence sensibly reduces the memory requirements, compared to our previous method that precalculates the lists. It was also extended to permit a truncation of the string space, according to the level of ex...

We report the large scale syntheses and 'oxidative purification' of fcI(2), fcBr(2) and FcBr (fc = ferrocene-1,1'-diyl, Fc = ferrocenyl). These valuable starting materials are typically laborious to separate via conventional techniques, but can be readily isolated by taking advantage of their increased E(1/2) relative to FcH/FcX contaminants. Our work extends this methodology towards a generic ...

The pcalg package for R (R Development Core Team 2014) can be used for the following two purposes: Causal structure learning and estimation of causal effects from observational and/or interventional data. In this document, we give a brief overview of the methodology, and demonstrate the package’s functionality in both toy examples and applications. This vignette is an updated and extended (FCI,...

In this paper we review several existing tools for fault injection and dependability benchmarking in grids. We emphasis on the FAIL-FCI fault-injection software that has been developed in INRIA Grand Large, and a benchmark tool called QUAKE that has been developed in the University of Coimbra. We present the state-of-the-art and we explain the importance of these tools for dependability assessm...

Las medidas de bioseguridad han sido diseñadas para salvaguardar la vida, actualmente en tiempo pandemia originada por enfermedad del COVID- 19 es cuanta más importancia cobra su aplicación, incorporando una serie acciones contrarrestar el virus, debido a que aún no existe un tratamiento específico o alguna vacuna detenga incubación virus humanos. La presente investigación tiene como finalidad ...

In a network consisting of several thousands computers, the occurrence of faults is unavoidable. Being able to test the behavior of a distributed program in an environment where we can control the faults (such as the crash of a process) is an important feature that matters in the deployment of reliable programs. In this paper, we extend FAIL-FCI (for Fault Injection Language, and FAIL Cluster I...

This paper presents a framework for assessing the fiscal condition index (FCI) and develops a concept to assess fiscal condition of governments and implements it into Iran government as an oil exporting country. The concept consists of four dimensions ­-revenue, expenditure, budget balance, and debt structure-and each dimension has its own indicators. There are seven indicators examined namely ...
