Alignment of sequence reads is an important step of many bioinformatics workflows. While the alignment of short reads is well investigated, the alignment of long reads produced by third-generation sequencing technologies, such as Oxford Nanopore, is more challenging because they have high error rates (10–40%). Furthermore, due to their different algorithmic approaches, different tools produce varied...
In this work, a job-flow scheduling approach for Grid virtual organizations (VOs) is proposed and studied. Users' and resource providers' preferences, VOs internal policies, resources geographical distribution along with local private utilization impose specific requirements for efficient scheduling according to different, usually contradictive, criteria. With increasing resources utilization level...
The research quantitatively proved, that the popular today the mode for estimating risks in operators actions based on uses of exponential probability distribution function (PDF) of time between mistakes of operators is a rough and unpromising engineering way. Its application deforms very essentially probabilistic estimations of risks. Operator may be a man or special device or their combination....
Block ciphers are very important in communication systems as they provide confidentiality through encryption. Today's block ciphers need not only high cryptographic security but also high performance encryption and decryption, as well as the ability to adapt in special environments. This paper focuses on improving the security and performance of AES-256 algorithm, based on improving diffusion layer...
Base station cooperation is a promising scheme to improve network performance for next generation cellular networks. Up to this point research has focused on station grouping criteria based solely on geographic proximity. However, for the cooperation to be meaningful, each station participating in a group should have sufficient available resources to share with others. In this work we consider an...
Extensive regions of the Mediterranean Region are currently facing serious problems regarding the supply of sufficient water resources to cover their increasing water supply demands. In the year 2025, several countries will have less than 200 cubic meters per capita per year. This problem of water scarcity in the region is continuously aggravating: while the renewable water resources decrease, the...
Massive open online course (MOOC) exposes the challenge and subversion to the traditional mode of education, and its way of sharing information and knowledge brings a new revelation to integrating and sharing of knowledge resources in colleges and universities. This paper presents an integration and knowledge sharing mode based on the mixed mode of xMOOC and cMOOC which is compatible to knowledge...
This work has elaborated economically-mathematical models of forming production program with homogenous product taking into account market demand, average labor of product, transferred mature product stocks, free store volume and other basic resources, realized with both own means and credit under simple interests, allowing optimal coordinating material flows and presenting enterprise financial resources...
Multi-Agent System (MAS) consists of innumerable independent and active units, called agents, which collaborate with each other to attain pre-determined goals or delegated objectives. Agents being uncoupled, scattered, event-driven and self-motivating in nature any MAS is distributed and large scale. Hence the analysis of MAS are intricate and crucial. This work proposes formal analysis method for...
Most human-environment interactions with regard to any natural resource occur on multiple scales. Furthermore, the “human” aspect of humanenvironment interactions always involves multiple communities of interest and identity, and the “environment” aspect always involves multiple dimensions, uses, and values of any natural resource. These facts pose a significant challenge in the design of institutions...
This chapter first outlines the background to the problem addressed by the preceding chapters, namely the computation using silicon-based hardware of the real-data DFT, including the specific objectives that were to be met by the research, this being followed with a further discussion of the results obtained from the research and finally of the conclusions to be drawn.
The western and the eastern man have the same intrinsic dignity. Whatever happens in the world, somehow it is always good because it gives us the chance to learn a lesson. Meanwhile world’s richest countries are mired in one deep crisis. There is a crisis in the National Health Service (NHS). The publication of the Health and Social Care Bill last week heralds dramatic changes for the NHS, which will...
Quantitative evaluation of enterprise core competence has great theoretical and practical significance for enterprise strategic management. On the basis of studying related literatures, this paper thought that resources and capabilities are the sources of competitive advantage. It constructed evaluation system of enterprise core competence based on resources and capabilities; proposed Nine Grids Chart...
In cooperative missions, if an individual UAV does not have sufficient resources to neutralize a target then a coalition of UAVs may needs to be formed that fulfills the target resource requirement. This paper proposes an algorithm for the decentralized coalition formation of multiple heterogeneous UAVs that cooperatively perform a search and attack task to neutralize the static ground targets. The...
Modern databases are crucial components of quality management systems according to the requirements of ISO 9001:2015, but their design and maintenance need significant resources. Despite the fact that modern databases are a key factor of management decision making, not all organizations can spend sufficient resources on their development what results in the necessity to find a model for database maintenance...
A network-flow method is proposed for decision making in intelligent resource flow networks systems considering the risk on the particular parts of the network. We initially assume that the probability of an adverse event happening on all sections of the network is of the same value.
This paper introduces the concept of information management and work steps. From the application view of the implementation phase, especially the information management in the construction phase can explain the importance of the project information management. And project status and development of information management are discussed.
The article presents the problem of identification and analysis of processes and resources of the logistics system in management of the Division of the Assay Office in Czestochowa (Poland) in the process of determination of gold content in jewelry alloys. In the fundamental process, developed in the logistics system of the administrative body, i.e. in the process of determination of gold content in...
With the resource constraints of Internet of Things (IoT) devices, performance and energy efficiency have become an important IoT software design consideration while minimizing resource usages. To provide efficient communication for resource-constrained applications, several IoT protocols have been introduced, and yet there are few existing guidelines to help the programmer choose an appropriate communication...
Nowadays, virtualization is present in almost all cloud infrastructures. In virtualized cloud, virtual machines (VMs) are the basis for allocating resources. A VM is launched with a fixed allocated computing capacity that should be strictly provided by the hosting system scheduler. Unfortunately, this allocated capacity is not always respected, due to mechanisms provided by the virtual machine monitoring...
