Although legal personality has slowly begun to be granted non-human entities that have a direct impact on the natural functioning of human societies (given their cultural significance), same cannot said for computer-based intelligence systems. While this notion not had significantly negative humanity point in time only remains case because advanced computerised systems (ACIS) been acknowledged ...

The Advanced CCD Imaging Spectrometer (ACIS) on the Chandra X-ray Observatory is suffering a gradual loss of low energy sensitivity due to a buildup of a contaminant. High resolution spectra of bright astrophysical sources using the Chandra Low Energy Transmission Grating Spectrometer (LETGS) have been analyzed in order to determine the nature of the contaminant by measuring the absorption edge...

A novel Adaptive Color Image Segmentation (ACIS) System for color image segmentation is presented. The proposed ACIS system uses a neural network with architecture similar to the multilayer perceptron (MLP) network. The main difference is that neurons here uses a multisigmoid activation function. The multisigmoid function is the key for segmentation. The number of steps i.e. thresholds in the m...

We examined 11 cases of carcinoma arising from Barrett's esophagus consisting of two adenocarcinomas in situ (ACIS), two intramucosal adenocarcinomas, and seven overt invasive adenocarcinomas. Overexpression of p53 (implying a mutation of the p53 gene), ERBB2, and EGFR was measured by immunohistochemistry, and gene amplification of ERBB2 and EGFR was measured by fluorescence in situ hybridizati...

Segregation is one of the major phenomena decreasing durability concrete and increasing its risk failure. This paper investigates feasibility AC Impedance Spectroscopy (ACIS) to serve as a monitoring technique for segregation during compaction. The impedances fresh were determined between compaction intervals. Changes in calculated bulk resistivities compared hardened densities drilled cores, w...

Alternating current impedance spectroscopy (ACIS) was used to assess the effect of different sand, anhydrite and water contents on electrochemical response Portland cement paste in early stages hydration. Potential factors that may affect measurements data interpretation are also discussed, such as complexity chemical composition cement, its physical properties hydration kinetics, technique lim...

Background and purpose Carotid webs (CaW) may be an under-recognized cause of anterior circulation cryptogenic ischemic stroke (ACIS). Prevalence is still unknown in European patients with ACIS. Objective To evaluate the prevalence CaW ACIS describe phenotype a cohort from French center. Methods We conducted retrospective monocentric study 01/01/2015 to 31/12/2019 (Montpellier University Hospit...

Developing an awareness of the challenges entailed in the protection of Critical Infrastructures is an important first step. Before one can take effective measures to improve the protection of Critical Infrastructures, it is necessary to understand how these function and to identify and analyse the critical processes within the Critical Infrastructures. The ACIS methodology described in this pa...
