Inorder to recognize the driver's visual distraction in the driving process, this paper chooses the information of pupil diameter as an indicator to study. At first, it designs three typical experimental scenarios of following, overtaking, and target search according to the research goal, selects 12 subjects and does the experiment of distracted driving using the driving simulation platform and the eye tracker. Then, the data is processed and repaired. After the static experiment verification threshold, the difference of the pupil diameter value was treated. The method of sliding standard deviation is used to automatically identify the abnormal mutation of pupil diameter, and use linear interpolation to repair. Finally, by the methods of variance, mean square root and recursive graph, this paper analyzes the changes of pupil diameter in three scenes such as gallop, overtaking and target search, and realizes the recognition of driver's visual distraction. The research results show that the changes of drivers' pupil diameter is more stable and small discrete degree in normal driving condition, on the contrary it is unstable and large discrete degree in distracted driving. At all, it can analyze the pupil diameter using means of variance, mean square root and recursion graph, and identifies the driver's visual distraction behavior.

Over the past 5-10 years, the hair fixative industry has undergone somewhat of a metamorphosis due largely to changes in hair styles and a new surge in creativity in both the salon and consumer retail segments. Greater segmentation of the market is a continuing trend. New product forms and formulations have emerged. In this presentation, the author reviews polymers and formulations in the context of newer product types and market trends.

During last few years, the interest in using natural fibers as reinforcement in polymers has increased significantly. Natural fibers are not only strong and lightweight but also relatively very cheap and bio-degradable. In this work, an investigation is carried out on jute fiber, a natural fiber. Jute fiber has gained interest in the composite field due to its superior specific properties compared to manmade synthetic fibers like glass, Kevlar, asbestos, etc. The present work describes the development and characterization of natural fiber based composites consisting of jute fiber as reinforcement and hybrid resin consisting of general purpose resin and cashew nut shell resin as matrix material. The composites are fabricated using hand lay-up technique. The tensile strength is studied using experimental and numerical analysis. The nature of hybrid matrix at different composition is also studied. The commercial Finite Element Analysis software ANSYS is used for numerical study.
Degradable polymers and compositesComposites have found extensive applications in various industries but are currently limited to low-temperature usage due to their low glass transition temperature (typically 130 ...

This study is an attempt to analyze the load - settlement behavior of short composite caisson foundation using the continuum approach. The steining considered to be rigid, undergoes rigid body translation and hence is treated as an incompressible cylinder while the core inside is analyzed as a compressible pile. Only compatibility of vertical displacements is considered in this analysis. The soil displacements are calculated at mid points of the outer surfaces of each element, and at the centers of bases of steining and granular core by integrating numerically the Mindlin's solution for a vertical point load inside a semi-infinite medium. A detailed parametric study is carried out to evaluate the relative influence of each parameter on the overall deformation response of the composite foundation. The results encourage the use of the above foundation for alluvial lowlands.
