The development of overhead costs management is becoming more and important as the percentage rising. last 15 years have demonstrated awakening advanced methods tools aimed at understanding utilization overheads better. paper investigates current state using a sample 20 companies in Austria, Hungary, Slovakia. A qualitative approach was applied multi-case study, which unveiled significance cost...

Revolving codes (ReC) are a new family of network that reduce signaling overhead and maintain high decoding probability, which is key in applications with small payloads, e.g., IoT, Industry 4.0. However, they have only been studied using simulations. We present i) the first exact mathematical model for total probability set ReCs, ii) efficient encoders decoders. Our analysis shows ReC decoders...

Streaming video algorithms dynamically select between different versions of a video to deliver the highest quality version that can be viewed without buffering over the client’s connection. To improve the quality for viewers, the backing video service can generate more and/or better versions, but at a significant computational overhead. Processing all videos uploaded to Facebook in the most int...

In this paper a reversible data hiding scheme based on shifting the histogram of host image blocks is presented. This method attempts to use full available capacity for data embedding by dividing the image into non-overlapping blocks. Applying histogram shifting to each block requires that extra information to be saved as overhead data for each block. This extra information (overhead or bookkee...

A tagged architecture is a system that applies tags on data, recently used in the field of information security. The previous studies using tagged architecture mostly focused on how to utilize tags, not how the tags are implemented. A naive implementation of tags simply adds a tag field to every byte of the cache and the memory. Such technique, however, results in a huge hardware overhead and p...

Measurement-based profiling introduces intrusion in program execution. Intrusion effects can be mitigated by compensating for measurement overhead. Techniques for compensation analysis in performance profiling are presented and their implementation in the TAU performance system described. Experimental results on the NAS parallel benchmarks demonstrate that overhead compensation can be effective...
