Two different visual servoing controls have been developed to govern a translating parallel manipulator with an eye-in-hand configuration, That is, a position-based and an image-based controller. The robot must be able to reach and grasp a target randomly positioned in the workspace; the control must be adaptive to compensate motions of the target in the 3D space. The trajectory planning strate...

Digital image processing has been applied to diverse industry disciplines. The wide application of digital image processing can be attributed to the following advantages: accuracy, objectivity, fastness, consistency, and the mixture of them. Although the RUst Defect Assessment(RUDA) method [1] was efficiently used to differentiate defective images from non-defective images on blue color coat, i...

Aspect graph is an important method in 3D object recognition. To effectively compute the viewpoint space partition (VSP) is critical in acquiring a good aspect graph. In this paper, we present improvements to the VSP algorithm under perspective model: computing EV (Edge Vertex) events using triangle face feature; simplifying VSP representation; boundary intersection updating; closed loop region...

The present study is an attempt to isolate and optimize the fermentation conditions of three fungus, namely Trichoderma virens, Alternaria alternata and Curvularia lunata to get pigments for the purpose of textile dyeing. Highest optical density has been achieved in potato dextrose broth at 28oC in 25 days under static conditions. Wool and silk are dyed unmordanted with very good wash and rub f...

The dyer has always been faced with choices regarding which dye to use and which application process to choose. In previous years, the cost of the dyeing process and the fastness of the dyeings obtained were prime considerations. Today these basic needs have been supplemented by the need for high productivity in the dyehouse together with an awareness of the environmental impact of the dyeing p...

To identify a fast and sensitive method for screening for mutations in patients with imatinib- resistant chronic myeloid leukemia (CML), we compared allele specific oligonucleotide- polymerase chain reaction (ASO-PCR) assay with conventional direct sequencing. Among the 68 imatinib resistant CML patients studied, 18 amino acid substitutions were detected in 44 patients by two assays. The sensit...

We show that the diverse ecoregions of Madagascar share one distinctive climatic feature: unpredictable intra- or interannual precipitation compared with other regions with comparable rainfall. Climatic unpredictability is associated with unpredictable patterns of fruiting and flowering. It is argued that these features have shaped the evolution of distinctive characteristics in the mammalian f...

1. The unsaponifiable fractions of the Mycobacteria, though insoluble in water and extremely stable chemical compounds, are nevertheless remarkable stimulants of cells. 2. They give rise to new monocytes which surround these waxes and then fuse into giant cells which engulf them. 3. The property of acid-fastness of the waxes makes it possible to identify them within the giant cells which have p...

The proposed contribution describes a method for the detection and classification of harmonic transients, as they occur in electrical networks. The method uses, as bases, a special class of wavelet-packets, i. e. smooth biorthogonal sine and cosine-packets in order to find the best ’’Shannon-basis“. The algorithm is based on the minimization of Shannon‘s function for the decomposed wanted signa...
