Efficient algorithm for discrimination of overlapping ultrasonic echoes

Next Generation NDE Sensor Systems as IIoT Elements of Industry 4.0

“…Deconvolution techniques became increasingly elaborate with the growing availability of digital signal processing power [7][8][9]. With the advent of the field of Compressed Sensing (CS) after the seminal papers by Candes and Tao [10], the field of sparse signal processing was revived and a sparse perspective on deconvolution techniques led to a slightly different view on deconvolution techniques as well [11][12][13][14]. Based on these concepts, inversion techniques with sparsity-aware regularizers were discussed more recently [15][16][17].…”

Heck reaction of alkyl halides and α-selective heck reaction of styrenes

“…5 Resveratrol is an antioxidant commonly found in grapes, polygonum cuspidatum and red wine, which is beneficial to human health in a number of ways such as cardiovarscular protective effects and lifespan extension. 6 DSM applies the Heck reaction as a key step for the total synthesis of resveratrol which is commercialized as resVida ® in the market (Scheme 1.1, b). 7 The key monomers for the production of Dow's CYCLOTENE™ advanced electronics resins are also produced based on Heck reaction (Scheme 1.1, c).…”

“…4 Eli Lilly uses the Heck reaction to produce the feedstock en route to pemetrexed disodium heptahydrate (tradename Alimta®), which is a chemotherapy drug for the treatment of non-squamous non-small cell lung cancer and malignant pleural mesothelioma (Scheme 2.1, b). 5 Quest international (acquired by Givaudan)used Heck reaction as a key step to access novel fragrance compounds (Scheme 2.1, c) 6. Perfumes containing these ingredients showed strong and pleasant odour, good substantivity to hair and cloth, antibacterial and antimicrobial properties, etc.…”
