The fact that real-world decisions made by artificial intelligences (AI) are often ethically loaded has led a number of authorities to advocate the development “moral machines”. I argue project building “ethics” “into” machines presupposes flawed understanding nature ethics. Drawing on work Australian philosopher, Raimond Gaita, ethical dilemmas problems for particular people and not (just) eve...

The present work focuses on the physicochemical characterization of selected mineral-based biomaterials that are frequently used in dental applications. The selected materials are commercially available as granules from different biological origins: bovine, porcine, and coralline. Natural and calcined human bone were used for comparison purposes. Besides a classical rationalization of chemical ...

The porosity within a reservoir rock is a basic parameter for the reservoir characterization. The present paper introduces two intelligent models for identification of the porosity types using image analysis. For this aim, firstly, thirteen geometrical parameters of pores of each image were extracted using the image analysis techniques. The extracted features and their corresponding pore types ...

permeability is a property of porous medium that quantifies rock capacity to transmit fluids. frequently, core based permeability data are not available either because of the borehole conditions or due to the high cost of coring. for these reasons, over the years attempts have been made to estimate permeability by alternative ways. permeability is an elusive parameter in hydrocarbon reservoirs ...

Zirconia particles were prepared from a 20% colloidal sol (ZrO2) by the polymer­induced colloid ag­ gregation (PICA) process, both in the presence and absence of porogens. Specifically, porous zirco­ nia particles having varying porosity were prepared by a two­step protocol wherein a porogen was first embedded during the particle synthesis, followed by its removal in a subsequent step. In this ...

Porous Silicon (PS) layers have been prepared from p-type silicon wafers of (100) orientation. SEM, XRD, FTIR and PL studies were done to characterize the surface morphological and optical properties of PS. The porosity of the PS samples was determined using the parameters obtained from SEM images by geometric method. The refractive index values of the PS samples as a function of poros...
