The three electromagnetic properties appearing in Maxwell’s equations are dielectric permittivity, electrical conductivity and magnetic permeability. The study of point diffractors in a homogeneous, isotropic, linear medium suggests the use of logarithms to describe the variations of electromagnetic properties in the earth. A small anomaly in electrical properties (permittivity and conductivity...

The Cognitive Reflection Test (CRT) is a hugely influential problem solving task that measures individual differences in the propensity to reflect on and override intuitive (but incorrect) solutions. The validity of this three-item measure depends on participants being naïve to its materials and objectives. Evidence from 142 volunteers recruited online suggests this is often not the case. Over ...

This research paper investigation concerned with understanding the mechanisms and designing a rules of Metacontrol and Metacognition. This work investigated the concept of metacognition as a powerful catalyst for control, unify and self-reflection. Metacontrol is a part of the Metacognition task. Metacontrol rules decides which deliberative agents are to be learned and ready to perform in diffe...

Learner reflection has been found important and valuable, especially in cognitively intensive tasks, such as learning programming. This paper presents, K-Assess, a programming education system that facilitates student self-evaluation and promotes learner reflection. It is built on top of an existing conventional programming teaching system by adding a pragmatic knowledge layer. Our evaluations ...

A method for automatic horizon tracking in reflection seismic data images across discontinuities is described. Horizon tracking is an important task of the structural interpretation of seismic images, however the automatic tracking across discontinuities has still not been solved satisfactorily. The reason for this is the difficulty involved in locating non-ambiguous local correlation features ...

The present study examined the relation between cognitive response styles (i.e., brooding, reflection, distraction) and cognitive inflexibility in differentially predicting history of non-suicidal self-injury (NSSI) only, suicide attempt (SA) only, or both (NSSI + SA). College students (N = 352) completed self-report measures of rumination, distraction, and self-harm history, a diagnostic inter...

Emergency planning is an ongoing activity in which a multidisciplinary group of experts intermittently collaborate to define the most appropriate response to risks. One of the most important tasks of emergency planning is risk reduction. Such a task compiles the analysis of capabilities to face an emergency, the prioritizing of activities, and the definition of procedures and strategies. It is ...

When subjects are required to reason about someone's false belief, a consistent pattern of brain regions are recruited including the medial prefrontal cortex, medial precuneus and bilateral temporo-parietal junction. Previous group analyses suggest that the two medial regions, but not the lateral regions, are also recruited when subjects engage in self-reflection. The current study directly com...

The aim of this work is to review the current status of photovoltaic (PV) power generation, focusing on concentrating PVs mainly as regards their typology, market and state-of-the-art feature. The incorporation of a heat recovery system can increase the overall efficiency by exploiting the waste heat. The proposed solution is a Solar Polygeneration System (PROTEAS System) for the simultaneous p...

This paper describes a prototype of a simulaled physics student that learns by interacting with a human tutor. The system solves physics problems while showing its work on a work· station screen, and the tutor can intervene at cenain points during problem·solving to advise the simulaled studenL This prototype constitutes an initial cognitive task analysis of the skill of learning from a tutor, ...
