An adaptive blind watermarking scheme utilizing neural network for synchronization is proposed in this paper,which allows to recover watermark even if the image has been subjected to generalized geometrical transforms. Through classification of image’s brightness, texture and contrast sensitivity utilizing fuzzy clustering theory and human visual system, more robust watermark is adaptively embedded in DWT domain. In order to register rotation, scaling and translation parameters, feedforward neural network is utilized to learn image geometric pattern represented by six combined low order image moments. The distortion can be inverted after determining the affine distortion applied to the image and watermark can be extracted in a standard way without original image. It only needs a trained neural network. Experimental results demonstrate its advantages over previous method in terms of computational effectiveness and parameter estimation accuracy. It can embed more robust watermark under certain visual distance, and effectively resist JPEG compression, noise and geometric attacks.展开更多

For recovery these valuable mineral, a gravity concentrator viz. wet shaking table was used.Optimisation along with performance prediction of the unit operation is necessary for efficient recovery.So, in this present study, an artificial neural network(ANN) modeling approach was attempted for predicting the performance of wet shaking table in terms of grade(%) and recovery(%). A three layer feed forward neural network(3:3–11–2:2) was developed by varying the major operating parameters such as wash water flow rate(L/min), deck tilt angle(degree) and slurry feed rate(L/h). The predicted value obtained by the neural network model shows excellent agreement with the experimental values.展开更多

The experiment data about the performance of the DEC air conditioner are obtained. Some experiment data are used to train the network until these data can approximate a function, then, simulate the network with the remanent data. The predicted result shows satisfying effects.展开更多

After a thorough neurological examination and neuroimaging, structural causes were excluded and thus the dysarthria was attributed to the irinotecan infusion. A slowing down of the infusion rate to 180 min during the 15 subsequent cycles led to the cessation of the episodes of dysarthria. In 2016, it was estimated there will be 134,490 new cases of colorectal cancer with a five-year survival rate of 21% among patients with metastatic disease. As Irinotecan is often part of the therapeutic regimen in such cases, both in the first and second-line setting, there is a need to report rare adverse outcomes in order to fmd out ways to better manage of these events. The mechanism by which Irinotecan causes dysarthria is unknown and further research in this area is warranted.展开更多

The author is critical of these arguments and believes that the symptoms of crawling and pin-pricking are genuine; just misinterpreted as parasite movements. Based on the author＇s research on over 1000 ＂delusional＂ patients since 1996 at the Parasitology Center, Inc. （PCI）, the author has established that the symptoms of crawling and pin-pricking are caused by toxicity from exposure to incompatible dental materials, implants, environmental toxins among others that alter the propagation of normal nerve impulses. The author has also observed that external parasites/organisms including springtails （Collembola）, other arthropods, bacteria, and fungi represent only opportunistic infections of skin sites compromised by the toxicity disorder involving the elimination of toxins through the skin. The author has described a new pathological disorder, Neuro-cutaneous Syndrome （NCS） primarily associated with dental toxicity to which ＂delusional parasitosis＂ and Morgellons disease cases could be assigned. The author has developed a protocol for the resolution of the symptoms of NCS cases. When followed to the letter, all symptoms of NCS, conventionally called delusional parasitosis, are invariably and irreversibly resolved; each individual＇s unique circumstances taken into account. The author is also presenting a detailed case history of an NCS patient that has recovered from her experiential personal perspective.展开更多

A conventional method is to control the equipment such that the temperature of hot water supply is maintained at a set-point that may be a fixed value or be compensated against the external temperature. This paper presents a novel scheme that can determine the optimal set-point of hot water supply that maximizes the energy efficiency whilst providing sufficient heating capacity to the load. This scheme is based on Adaptive Neuro-Fuzzy Inferential System. The aim of this study is to improve the overall performance of district heating systems.展开更多

Under conditions in which the crush force is too great, the digits are not viable candidates for replantation. We present two cases in which the patients suffered from loss of the thumb ray at the first carpometacarpal joint and skin defect at the radial side. The tendons, radial nerve and metacarpal bone of the index finger were injured, and the second metacarpal head was retained. There was a comminuted fracture of the trapezium in both patients. The treatment protocols consisted of the index finger pollicization and the free anterolateral thigh flap transfer. The procedure was performed in a single operation. The new thumb is able to provide a stable post for pinch and grip after six months follow-up. Both patients were satisfied with the function and appearance of the reconstructed thumb.展开更多
