Exploring the bronzing effect at the surface of ink layers

We i nvestigate the optical phenomenon responsible for the colored shine that sometimes a ppears at the surface of ink layers i n t he s pecular direction, o ften ca lled bronzing or gloss di fferential. I t seems to co me from the w avelengthdependent refractive index of t he ink, which induces a wavelength-dependent reflectance of t he i nk-air interface. Our experiments o n c yan and magenta...

Analysis of lumpiness phenomenon in MRP

Occurrence of chaotic behaviors because of fluctuations creation and their intensified transfer along the chain is one of the main causes of inefficiency of Material Requirements Planning (MRP) based supply chains. One of the reasons of the inefficiency is the lumpiness phenomenon. Through this phenomenon, some parts have an irregular production schedule, with nothing produced in some periods a...

Anatomical and Histochemical Factors Associated with Bronzing Development in Strawberry Fruit

Bronzing of strawberry (Fragaria ×ananassa Duchesne) fruit that is not the result of arthropod feeding or chemical spray application occurs frequently in California’s central coast strawberry production region from late spring through midsummer, a period characterized by relatively high temperature, low relative humidity, and high solar irradiance. The cause of this phenomenon is not known, but...
