Revision with unchanged content. Cognitive Load Theory focuses on several assessment techniques to assess overall cognitive load, including its three-subclasses, and its relationship to learning. Methods include psychophysical and secondary task techniques, along with task performance and self report. This book looks to review two popular self-report measures (NASA Task Load indeX, and a short subjective instrument) and identify not only if they are consistent with one another, but also to discover whether both are equally sensitive across changes in levels of cognitive load subclasses. The two subclasses looked at in this work are intrinsic load, which is related to element interactivity, and extraneous load, which is influenced by the instructional design. Results from this work show that the NASA-Task Load index, as a weighted multi-dimensional rating scale, differs in measurement of the demands faced by learners in a PC-based, multimedia-learning environment from the more traditional,single question, short subjective instrument. This book is primarily addressed to developers of mutlidmedia educational materials for online or interactive studies. Researchers and practitioners alike should benefit this book.

The fascination of reciprocal frameworks lies in the effortlessness and lightness of their seemingly interwoven elements. The diversity of the forms and patterns of these constructions are created by an interaction of mutually supporting members a technique already exploited by master builders hundreds of years ago. The first part of the book examines the history of this load-bearing principle, which is little known today but stretches from Renaissance master architects such as Leonardo da Vinci right up to current architectural practice. The second part of the publication provides an insight into the principle s intrinsic system, and provides examples of how it is possible using digital tools to expand the current applicational fields of reciprocal frameworks.

One of the main obstacles when using embarked electrical sources, such as batteries or fuel cell, lies in the inertia of this kind of devices, which limits dynamic performances, and in the case of batteries, range and lifetime. The management of embarked electrical energy needs a storage system for peak load shaving, in order to compensate for the intrinsic limitations of the main source. The use of supercapacitors for this storage system is quite suitable, in regard to their energitical properties. This thesis deals with the sizing of the storage device (energy, power, and voltage), the control of the interface converters of hybrid power sources using supercapacitors and the management of transient power peaks between different element of the system. This study is illustrated by the achievement and the test of two experimental hybrid sources. The first is based on the association of batteries and supercapacitors, and the second is an example of voltage regulated DC Hybrid source.

Ferrite is a class of magnetic material. Naturally occurring ferrite is the ferrous ferrite (Fe3O4) as "Load Stone". In early days it was considered as ferromagnetic material. But latter on L Neel realized that, material consists uncompensated anti parallel spin arrangement and hence named as "Ferrimagnetic material. Ferrite is a special class of Ferrimagnetic material having interesting intrinsic properties. Basically Farous ferrite Fe3o4 is having double oxides FeO & Fe2O4. The properties can be altered by substituting divalent iron ion by divalent cations from transition elements. Properties can be significantly modified by substituting trivalent iron ion by another trivalent cations. Ferrites are found to be technologically and commercially useful magnetic material. Due to highly electrically resistive and low magnetic behavior as well as negative temperature coefficient of resistance along with low magnetic loss ferrites can be used at high frequencies. They find applications in the fields like elecommunications, electronic industries, data storage & processing. Aluminum substituted Copper CuxAl2yFe2-2y ferrites are prepared to study structur, electrical & magnetic properties.
