THE DESIGN AND ANALYSIS OF EXPERIMENTS. By Oscar Kempthorne. New York, John Wiley and Sons, Inc., 1952. 631 pp. $8.50. This book by a teacher of statistics (as well as a consultant for \"experimenters\") is a comprehensive study of the philosophical background for the statistical design of experiment. It is necessary to have some facility with algebraic notation and manipulation to be able to use the volume intelligently. The problems are presented from the theoretical point of view, without such practical examples as would be helpful for those not acquainted with mathematics. The mathematical justification for the techniques is given. As a somewhat advanced treatment of the design and analysis of experiments, this volume will be interesting and helpful for many who approach statistics theoretically as well as practically. With emphasis on the \"why,\" and with description given broadly, the author relates the subject matter to the general theory of statistics and to the general problem of experimental inference.

Thermal conductivity of carbon nanotubes and their polymer nanocomposites: A review

Human skin is a remarkable organ. It consists of an integrated, stretchable network of sensors that relay information about tactile and thermal stimuli to the brain, allowing us to maneuver within our environment safely and effectively. Interest in large-area networks of electronic devices inspired by human skin is motivated by the promise of creating autonomous intelligent robots and biomimetic prosthetics, among other applications. The development of electronic networks comprised of flexible, stretchable, and robust devices that are compatible with large-area implementation and integrated with multiple functionalities is a testament to the progress in developing an electronic skin (e-skin) akin to human skin. E-skins are already capable of providing augmented performance over their organic counterpart, both in superior spatial resolution and thermal sensitivity. They could be further improved through the incorporation of additional functionalities (e.g., chemical and biological sensing) and desired properties (e.g., biodegradability and self-powering). Continued rapid progress in this area is promising for the development of a fully integrated e-skin in the near future.

Hygro-Thermal Behavior of Cement Mortar and Polystyrene Concrete

This study deals with the estimation of thermophysical properties of concretes containing a phase change material (PCM) from a single well designed experiment. This building material is obtained by the inclusion of micro encapsulated phase change materials, up to a specific volumetric percentage, in concretes. Three thermocouples and two heat flux sensors were carefully imbedded inside a solid flat plate of PCM and then submitted to specific heating cycle. Thermal properties are obtained by the solution of an appropriate inverse heat conduction problem that’s uses measured temperatures and/or heat flux taken inside the plate. Specific heat model is used to take into account the solid/liquid phase occurring inside the wall. First results, show the estimation feasibility by using temperatures or heat flux as additional information in the inverse problem. Thus thermal conductivity and specific heat of the material were estimated with a high accuracy. Preliminary computations show a good estimation of the specific heat as temperature function. The objective of this study to show that estimation of thermophysical properties in real-use conditions is better than the conventional methods such as differential scanning, thermal differential scanning, when available measurement are of high quality, is reached.
