In view of the frequent multimedia data transfer authentication and protection of images has gained importance in today’s world. In this paper we propose a new watermarking technique, based on bit plane, which enhances robustness and capacity of the watermark, as well as maintains transparency of the watermark and fidelity of the image. In the proposed technique, higher strength bit plane of di...

It is very pleasing for human health that medical knowledge has increased and the technological infrastructure improves systems. The widespread use of imaging devices been instrumental in saving lives by allowing early diagnosis many diseases. These images are stored large databases purposes. datasets used when a suspicious diagnostic case encountered or to gain experience inexperienced radiolo...

We propose two H.264 bit rate prediction and selection applications based on features extracted for our blind video quality assessment (VQA) algorithm, Video BLIINDS. We describe the blind VQA algorithm briefly, and we show that is correlates highly with human judgments of quality. We then demonstrate two applications: an H.264 bit rate predictor and an H.264 bit rate selector. Keywords-Video q...

We examine site selection diversity transmission (SSDT) for 3GPP WCDMA forward link by means of analytical tools. Hard handover (HHO), soft handover (SHO) and SSDT are compared by using the receiver bit error probability as a performance measure taking into account the effect of feedback bit errors as well as the shadow fading. Results show that without fast transmission power control the perfo...

This article describes a methodology which supports evaluation of bit preservation strategies for different digital materials. This includes evaluation of alternative bit preservation solutions. The methodology presented uses the preservation planning tool Plato for evaluations, and a BR-ReMS prototype to calculate measures for how well bit preservation requirements are met. Planning storage of...

The study of rotary steering drilling technology is currently one of the hot topics in the drilling engineering field. It requires accurate well trajectory control instructions when rotary steerable tools are applied to achieve the well trajectory control goal. A drilling trajectory prediction model will benefit this progress. According to the continuous beam theory, a mechanical model of push-...
