"This comprehensive new book deals with motion estimation for autonomous systems from a biological, algorithmic and digital perspective. An algorithm, which is based on the optical flow constraint equation, is described in detail. This algorithm fits with the motion processing model, hardware and software constraints and resolves depth-velocity ambiguity, which is critical for autonomous navigation. There is also extensive coverage on the use of this algorithm in digital hardware and describes both the initial motion processing model, the chosen hardware platforms, and the global function of the system."

"Sintesis nanopartikel Ni OH 2 Ni OH 2NP telah berhasil dilakukan menggunakan metode pengendapan kompleks dengan keadaan hidrotermal. Ni OH 2NP dikarakterisasi menggunakan Spektrofotometer UV-Visible, Fourier Transform InfraRed FTIR , X-Ray Diffraction XRD , dan Transmission Electron Microscopy TEM . Metode Anodic Stripping Voltammetry ASV menggunakan elektroda Boron-doped Diamond BDD digunakan untuk penentuan konsentrasi Ni OH 2NP secara elektrokimia. Kondisi optimum yang diperoleh dari hasil penelitian ini adalah potensial deposisi -600 mV, waktu deposisi 90 sekon, scanrate 100 mV/s pada larutan HClO4 pH 1. Kurva kalibrasi menunjukkan bahwa ASV Na OH 2NP linier pada rentang konsenstrasi 5-25 ?M dengan limit deteksi LOD 0,481 ?M. Ni OH 2NP kemudian dikonjugasikan dengan antibodi melamin yang telah dipurifikasi Ni OH 2NP-Ab dan dikarakterisasi dengan spektrofotometer UV-Visible, FTIR, zeta potensial, dan TEM. Ni OH 2NP-Ab kemudian digunakan sebagai pengenal dalam strip test immunokromatografi untuk mendeteksi melamin dengan asumsi konsentrasi melamin berbanding lurus dengan Ni OH 2NP-Ab. Pengujian strip test immunokromatografi sebagai perangkat sensor untuk deteksi melamin secara kuantitatif dilakukan dengan metode ASV menggunakan elektroda BDD dengan kondisi seperti pada pengujian Ni OH 2NP. Strip test yang difabrikasi berhasil mendeteksi melamin secara linier R2 = 0,9605 pada rentang konsentrasi 25 ndash; 250 ppm dengan LOD 53,90 ppm.
The synthesis of Ni OH 2 nanoparticles Ni OH 2NPs has been successfully performed using hydrothermal complexation precipitation method. Ni OH 2NPs were characterized by UV Visible Spectrophotometer, Fourier Transform InfraRed FTIR , X Ray Diffraction XRD , and Transmission Electron Microscopy TEM . Anodic Stripping Voltammetry ASV method at Boron doped Diamond BDD electrode was employed to determine the concentration of Ni OH 2NPs electrochemically. The optimum electrochemical conditions were obtained at the deposition potential of 600 mV, the deposition time of 90 seconds with a scanrate of 100 mV s in HClO4 pH 1 solution. Linear calibration curve showed that the ASV of Ni OH 2NP was linear in the concentration range of 5 25 M with limit of detection LOD of 0.481 M. The Ni OH 2NPs was then conjugated with purified melamine antibodies Ni OH 2NPs Ab and characterized by UV Visible spectrophotometers, FTIR, zeta potential, and TEM. The Ni OH 2NPs Ab was employed as the sensing in immunochromatographic strip test for the detection of melamine with assumption that the melamine concentration will be proportional with Ni OH 2NPs. The quantitative determination was determined by using the ASV method with BDD, which was previously optimized. The strip test can succesfully detect melamine linearly R2 0.9605 in the concentration range of 25 ndash 250 ppm with LOD of 53.90 ppm."

"Jahe merah telah lama dimanfaatkan sebagai salah satu obat tradisional untuk mengurangi peradangan atau inflamasi. Namun, herbal rimpang seperti jahe merah dilaporkan mengandung cemaran mikroorganisme yang relatif tinggi. Sehingga diperlukan metode sterilisasi untuk mendekontaminasi cemaran mikroorganisme tersebut. Iradiasi gamma sering menjadi pilihan untuk dekontaminasi, tetapi belum diketahui dosis yang efektif membunuh mikroorganisme dan tidak mempengaruhi kadar senyawa bioaktif serta aktivitas biologis jahe merah. Penelitian ini bertujuan mengevaluasi pengaruh iradiasi gamma terhadap cemaran mikroorganisme, kadar senyawa 6-gingerol, 8-gingerol,10-gingerol, dan 6-shogaol serta aktivitas antiinflamasi ekstrak etanol 70% jahe merah. Serbuk rimpang jahe merah terlebih dahulu diekstraksi dengan metode maserasi menggunakan etanol 70% 1:5. Ekstrak jahe merah kemudian diiradiasi dengan dosis 0, 5, 7,5, 10, dan 15 kGy. Evaluasi cemaran mikroba angka lempeng total dan angka kapang khamir dilakukan dengan metode tuang. Evaluasi kadar bioaktif dianalisis dengan metode Kromatografi Cair Kinerja Tinggi. Aktivitas antiinflamasi diukur dengan metode penghambatan denaturasi protein BSA dengan spektrofotometer UV-Vis. Efektivitas iradiasi sinar gamma dalam menurunkan angka cemaran mikroorganisme meningkat seiring meningkatnya dosis iradiasi (p<0,05). Kadar bioaktif 6-gingerol menunjukkan kadar yang paling tinggi diantara tiga senyawa bioaktif lainnya. Namun, secara keseluruhan dosis iradiasi gamma yang diberikan tidak berpengaruh signifikan terhadap kandungan 6-gingerol,8-gingerol,10-gingerol dan 6-shogaol dalam ekstrak etanol 70% jahe merah (p>0,05). Aktivitas antiinflamasi ekstrak etanol 70% jahe merah juga tidak berbeda signifikan setelah di iradiasi dengan dosis 0-15 kGy (p>0,05).
Red ginger has long been used as a traditional medicine to reduce inflammation. However, rhizome herbs such as red ginger are reported to contain relatively high levels of contamination by microorganisms. So a sterilization method is needed to decontaminate the microorganisms. Gamma irradiation is often an option for decontamination, but it is not yet known which dose is effective in killing microorganisms and does not affect the levels of bioactive compounds or the biological activity of red ginger. This study aims to evaluate the effect of gamma irradiation on contamination of microorganisms, levels of compounds 6-gingerol, 8-gingerol, 10-gingerol, and 6-shogaol, and the anti-inflammatory activity of a 70% ethanol extract of red ginger. Red ginger rhizome powder was first extracted by the maceration method using 70% ethanol at 1:5. The red ginger extract was then irradiated at doses of 0, 5, 7.5, 10, and 15 kGy. The evaluation of microbial contamination of the total plate count and yeast mold count was carried out by the pouring method. The evaluation of bioactive levels was analyzed using the high-performance liquid chromatography method. Anti-inflammatory activity was measured by inhibiting BSA protein denaturation with a UV-Vis spectrophotometer. The effectiveness of gamma irradiation in reducing the number of microorganisms contaminating the environment increased with increasing irradiation dose (p 0.05). The level of bioactive 6-gingerol showed the highest level among the other three bioactive compounds. However, overall, the dose of gamma irradiation given had no significant effect on the content of 6-gingerol, 8-gingerol, 10-gingerol, and 6-shogaol in the 70% ethanol extract of red ginger (p > 0.05). The anti-inflammatory activity of the 70% ethanol extract of red ginger was also not significantly different after irradiation with dose 0-15 kGy (p > 0.05)."
