We address in this paper automatic face verification from 3D (3-dimensional) facial surface and grey level analysis. 3D acquisition is performed by a structured light system, adapted to face capture and allowing grey level acquisition in alignment. The 3D facial shapes are compared and the residual error after 3D matching is used as a first similarity measure. A second similarity measure is der...

Considering the fact that Iran is situated in an arid and semi-arid region, rainfall prediction for the management of water resources is very important and necessary. Researchers have proposed various prediction methods that have been utilized in such areas as water and meteorology, especially water resources management. The present study aimed at predicting rainfall amounts using Grey Predicti...

Title The endocannabinoid system in the rat dorsolateral periaqueductal grey mediates fear-conditioned analgesia and controls fear expression in the presence of nocicpetive tone (2011). The endocannabinoid system in the rat dorsolateral periaqueductal grey mediates fear-conditioned analgesia and controls fear exp...

In this paper, grey system theory and DEA are combined to establish a grey DEA model. In traditional DEA model, Input and output values of decision-making groups are all real numbers and real variables. They are replaced by grey numbers and grey variables in grey DEA model respectively. Using positioning solution method of grey linear programming, we prove the necessary condition for grey effec...

A method to characterize time sequential stereoscopic 3D displays which is based on the measurement of the temporal behavior of the system versus grey levels is presented. OPTISCOPE SA, especially designed for precise measurement of luminance and temporal behavior of LCD displays is used. The transmittance and response time of the shutter glasses is first evaluated. Then the grey to grey respon...

The grey theory mainly works on systems analysis with poor, incomplete or uncertain messages. The popular grey model, GM(1,1) is efficient for long-term port throughput forecasting. However, it is imperfect when the throughput increases in the curve with S type or the increment of throughput is in the saturation stage. In this case, the throughput forecasting error of grey system model will bec...

Purpose – The purpose of this paper is to propose a grey linear control system for regulating the price of China’s real estate and provide the necessary support to assist the relevant management departments with their policy making. Design/methodology/approach – A grey state equation of the real estate market price that can reflect both the market supply-demand price mechanism and the productio...

Modern production processes are heavily reliant on industrial control systems (ICS) to help automate large-scale facilities. The security of these systems is paramount as evidenced by high profile attacks such as those against Iran’s nuclear facilities and the Ukrainian Power Grid. Existing research has largely focused on technical measures against such attacks and little attention has been giv...
