The paper reports results on the automation of the spray-painting process in industrial powder coating plants. The automation of the spray-painting process requires a painting model and the definition of appropriate metrics for painting task validation. Two main topics are addressed in the paper: motion planning of paint deposition and paint quality analysis. A paint quality function is formula...

In the current paper, the effect on Indoor Air Quality (IAQ) of two commercial acrylic-based paints were compared: one (Paint A) for indoor applications, the other (Paint B) for indoor/outdoor applications. Both were applied on an inert and on a real mortar substrate. The possibility of Paint B to passively improve IAQ was also investigated when adding highly porous adsorbent fillers, both as a...

A system is introduced for the simulation of spray painting. Head mounted display goggles are combined with a tracking system to allow users to paint a virtual surface with a spray gun. Ray tracing is used to simulate droplets landing on the surface of the object, allowing arbitrary shapes and spray gun patterns to be used. This system is combined with previous research on spray gun characteris...

background and aim: traffic accident is one of the main causes of mortality in iran. the damage and injury caused by these accidents threatens human societies severely. rural accidents are often more severe and show harsher consequences because the operational speed is higher on rural roads and highways. world statistics presented by world health organization (who) reveal that about 25 percent ...

This paper presents a novel countermeasure against Distributed Denial-of-Service (DDoS) attacks that we call the rouTer poRt mArking and paCKet filtering (TRACK), which includes the functions of both IP traceback and packet filtering. TRACK is a comprehensive solution that is composed of two components: a router port marking module and a packet filtering module. The former is a novel packet mar...

We have recently developed a calculus for dynamically evolvable aggregations of components. The calculus extends CCS with primitives for describing components and their evolvability capabilities. Central to these novel primitives is a restricted form of higher-order communication of processes involved in update operations. The origins of our calculus for components can indeed be traced back to ...

In this study, we developed a rapid nondestructive tool for testing rust spread in metal covered by paint layer using THz time-domain spectroscopy system at speed of 100 Hz/pixel. Time-of-flight imaging helps identify formation exclusively obtaining the reflection from steel below surface. The use frequency-selective allows us to manipulate contrast imaging. Higher is generally obtained when mo...

Understanding the mechanical properties of ancient paintings is a major issue for conservation and restoration. One strategy is to measure the mechanical properties of reconstructed paints: however the aging process is poorly known, so it is also desirable to measure mechanical properties directly on ancient paint samples. Using nanoindentation, we have characterized submillimetric samples reco...
