Two soluble nucleating agents were used to modify the optical properties of nine PP homo- and random copolymers. The ethylene content of the polymers changed between 0 and 5.3 wt %. Chain regularity was characterized by the stepwise isothermal segregation technique (SIST), while optical properties by the measurement of the haze of injection molded samples. Crystallization and melting characteri...

To report the possibility of post myopic photorefractive keratectomy (PRK) haze treatment in a patient with expressed reluctance for any additional laser therapy. Seven months after bilateral PRK with subsequent development of corneal haze and refractive regression in both eyes, a 37-old-year male patient presented a best-spectacle corrected visual acuity (BSCVA) of 20/30 in the right eye and o...

[1] We observed Titan in 1996–2004 with high-resolution 2 mm speckle and adaptive optics imaging at the W. M. Keck Observatory. By observing in a 2 mm broadband filter we obtain images that have contributions from both Titan’s surface and atmosphere. We have modeled Titan’s atmosphere using a plane-parallel radiative transfer code that has been corrected to agree with 3-D Monte Carlo prediction...

2 The cover image shows a true color subset of a Landsat-7 ETM+ scene with lake Constance at the Austrian-German-Swiss border (top left), acquired 2 June 2000. The top right image is the atmospherically corrected scene employing a haze removal over land and water. The haze removal over water is one of the new features of the 2011 release. The bottom part presents a zoomed view. The water mask i...

Free space optics (FSO) is an optical mean of communication where free space acts as a medium between transmitter and receiver and both should be in the line of sight for successful transmission of signal. Free space can be air, outer space, or vacuum. This system is economically beneficial than other systems and deployed in a matter of hours. This system poses great advantages like high bandwi...

Clear and wide-angle images are essential to detect and trace objects for applications such as CCTV and unmanned vehicles. Fog, haze, and rain causes problem in getting clear image and lowers the detection rate of objects. To remove haze, we use median dark channel prior which can reduce the complexity of hardware. Image stitching stitches a number of images from multiple cameras into single wi...

Outdoor images Outdoor images that are captured in inclement weather are degraded due to factors like haze and fog. This factor diminishes the visibility of the image. Haze is formed due to two fundamental phenomena namely, attenuation and the air light. Attenuation reduces the scene contrast and air light increases the whiteness in the scene. Images may also contain impulse noises which are pr...

The three typical extreme weather of fog, haze and dust storm have occurred frequently in recent years in 10 China. These events influence the transportation, the ecological environment, and the daily lives of people. Remote sensing is very important technology that can be used to monitor them due to its high temporal resolution and wide area of coverage. But because the spectral features of th...

Observations of the mass and chemical composition of particles less than 2.5 microm in aerodynamic diameter (PM2.5), light extinction, and meteorology in the urban Baltimore-Washington corridor during July 1999 and July 2000 are presented and analyzed to study summertime haze formation in the mid-Atlantic region. The mass fraction of ammoniated sulfate (SO4(2-)) and carbonaceous material in PM2...
