The rate regions and sufficiency of simple linear codes for a class of distributed storage systems.with prioritized data sources are investigated in this paper. The exact repair problem is considered. Different from conventional setups, the scenario considered in this paper has prioritized data sources, where the hot data has higher priority than cold data in the decoding process. It is assumed that a user demanding cold data demands hot data as well. Instead of using same capacity for all storage nodes, the rate regions of interest are all feasible different storage sizes versus different tuples of source entropies, with assumption of sufficient large repair bandwidth. Both symmetric and asymmetric repairs are discussed in the paper. Linear network codes over some finite field are said to be sufficient for such a distributed storage system if and only if for every point in the rate region, there exists a code over that finite field to achieve it. As a multi-source multi-sink network coding problem, the rate regions are obtained from computer-aided approaches via bounding the region of entropic vectors. Experimental results on the rate regions of hundreds of non-isomorphic distributed storage systems.are presented for demonstration. In addition, it is shown that binary linear codes suffice for most of them.

This paper provides a comprehensive literature review for water-filling algorithms and underground tunnel systems. Afterwards, an improved version of water-filling algorithm is proposed for distributed multi input multi output systems.in underground tunnels. The proposed algorithm is based on the conventional water-filling and Nash equilibrium approaches. It is believed that the designed scheme can enhance both the channel capacity and system performance for distributed multi input multi output in underground tunnel systems.

The paper introduces the challenge of scalability in machine learning algorithms suitable for massive datasets. Today, big data has relevant applications in the industry due to improvements in the system performance and by turning information into knowledge. Big data challenges include the lack of strategies to process computational cost and the large amount of data when computing machine learning predictions. To overcome these scalability issues, it is convenient to work with distributed and parallelized architecture across multiple nodes. The approach is based on Apache Spark, an in-memory distributed application that offers extensive machine learning libraries. The main contribution of the study is to measure the scalability by calculating the execution time that a classifier achieves with larger workloads. We validate our classifier models with experiments on logistic regression and random forest by studying their adaptability to the Apache Spark framework. The present work expects to combine the areas of big data and machine learning on scalability, and the use of optimization methods, cache and persist. In addition, a comparison between the classifiers is provided. The evaluation experiments show that logistic regression performed the shortest execution time and best scalability.
