A discussion of major issues related to the archiving of office business records

Based on our research and data analysis, we have made an in-depth study of the elements that have had an impact on the archiving of those office records from the automated office management system. In addition, we also offered a few suggestions about archiving such electronic office records more efficiently and effectively from a holistic perspective. In this paper, these authors discussed at some length about the following issues which included but limited to the unique features and requirements about the offline record transmission, the online record archiving, the requirements of electronic archiving stemming from the automated office document generating system, how to make the electronic business management system more congenial to its task-specific requirements for business records management and how to protect the system users' interest during the process of the system's continuous evolutionary development.

Automatic data archiving and visualization at HLS-Ⅱ

The control system of Hefei Light Source II(HLS-Ⅱ) is a distributed system based on the experimental physics and industrial control system(EPICS). It is necessary to maintain the central configuration files for the existing archiving system. When the process variables in the control system are added, removed, or updated, the configuration files must be manually modified to maintain consistency with the control system. This paper presents a new method for data archiving, which realizes the automatic configuration of the archiving parameters. The system uses microservice architecture to integrate the EPICS Archiver Appliance and Rec Sync. In this way, the system can collect all the archived meta-configuration from the distributed input/output controllers and enter them into the EPICS Archiver Appliance automatically. Furthermore, we also developed a web-based GUI to provide automatic visualization of real-time and historical data. At present,this system is under commissioning at HLS-Ⅱ. The results indicate that the new archiving system is reliable and convenient to operate. The operation mode without maintenance is valuable for large-scale scientific facilities.

Multi-objective fuzzy particle swarm optimization based on elite archiving and its convergence

A fuzzy particle swarm optimization （PSO） on the basis of elite archiving is proposed for solving multi-objective optimization problems. First, a new perturbation operator is designed, and the concepts of fuzzy global best and fuzzy personal best are given on basis of the new operator. After that, particle updating equations are revised on the basis of the two new concepts to discourage the premature convergence and enlarge the potential search space; second, the elite archiving technique is used during the process of evolution, namely, the elite particles are introduced into the swarm, whereas the inferior particles are deleted. Therefore, the quality of the swarm is ensured. Finally, the convergence of this swarm is proved. The experimental results show that the nondominated solutions found by the proposed algorithm are uniformly distributed and widely spread along the Pareto front.

The Way of Onitsha Market Literature： A Case for Proper Archiving of Nollywood Video Films

In contemporary times, many Nigerians, and indeed Africans, go through huddles to behold some of their most cherished artifacts in foreign lands. Such artifacts were taken away by the colonial masters during their various conquests of ancient African kingdoms. In the modern days as well, such trips are made to other countries by Nigerians and Africans to research into some popular arts and amusements lost as a result of neglect. One of such lost is the popular form of literature that once existed in the eastern part of Nigeria--the Onitsha Market Literature. Using evidences from secondary research materials, this paper discusses the re-occurrence of this silly history of neglecting the production and consumption of popular culture in Nigerian and indeed Africa. Using the Nigerian video film industry, Nollywood, as a case study, a case is here made for the proper archiving of these video films for future generations. It is observed that just few decades of video film production in Nigeria, virtually all the pioneer films cannot be found anywhere in the country. Such films must be needed in future for research purposes as the foundations upon which other great films of the future will base. The work therefore concludes with the obvious recommendation that genuine efforts, will, and finances be committed to proper archiving of legally approved Nollywood films. This will engender the sentiment central to film archiving and drastically reduce the problems that may confront the future generation as regards research in the Nigeria video film culture, Nollywood.

Audiovisual Archiving in Lithuanian Central State Archive

There are more than 800,000 units of audiovisual documents in the archive. The main laws regulating the activity of Lithuanian Central State Archive and related to audiovisual archiving are the Law on Documents and Archives of Lithuanian Republic, the Law of Cinema of Lithuanian Republic, and the Law on Copyright and Related Rights of Lithuanian Republic. There are four big collections of audiovisual documents in the Lithuanian Central State Archive--films, photo documents, sound recordings, and video recordings. The Archive＇s specialists have a large experience in the field of physical treatment and preservation of analogue audiovisual documents. Lithuanian Central State Archive digitizes audiovisual documents seeking the balance between long time preservation and nowadays access. Since May, 2010 till April 2013, Lithuanian Central State Archive implemented the project--Lithuanian documentaries on the Internet. During the project the Archives digitized and transferred to the Internet 1,000 titles of Lithuanian documentaries, created in the period 1919-1961. Lithuanian Central State Archive wants to popularize its collections, so various international projects are participated in.

Technology of Secure File Archiving in the Uniformly Random Distributed Archive Scheme

This paper investigates the security features of the distributed archive scheme named Uniformly Random Distributed Archive (URDA). It is a simple, fast and practically secure algorithm that meets the needs of confidentiality and availability requirements of data. URDA cuts a file archived into fragments, and distributes each fragment into randomly selected n -k + 1 storages out of n storages. As the result, users only need to access at least k storages to recover original file, whereas stolen data from k -1 storages cannot cover original file. Thus, archived files are nothing but sequences of a large number of fixed length fragments. URDA is proved of disappearing both characters and biased bits of original data in archived files, indicating the probabilities of both a fragment and a bit appearing at particular position are uniformly constant respectively. Yet, through running experiments, we found out the risk of likelihood that URDA might be vulnerable to bit pattern attack due to the different ratios of characters appearing in real world files. However, we solved the problem by modifying URDA with variable fragment lengths, which results in that all the bits in revealed sequences are distributed uniformly and independently at random.

Large-scale data archiving: At the interface of archive science and computer science

Both computer science and archival science are concerned with archiving large-scale data,but they have different focuses.Large-scale data archiving in computer science focuses on technical aspects that can reduce the cost of data storage and improve the reliability and efficiency of Big Data management.Its weaknesses lie in inadequate and non-standardized management.Archiving in archival science focuses on the management aspects and neglects the necessary technical considerations,resulting in high storage and retention costs and poor ability to manage Big Data.Therefore,the integration of large-scale data archiving and archival theory can balance the existing research limitations of the two fields and propose two research topics for related research-archival management of Big Data and large-scale management of archived Big Data.

TIFAflow: Enhancing Traffic Archiving System with Flow Granularity for Forensic Analysis in Network Security

The archiving of Internet traffic is an essential function for retrospective network event analysis and forensic computer communication. The state-of-the-art approach for network monitoring and analysis involves storage and analysis of network flow statistic. However, this approach loses much valuable information within the Internet traffic. With the advancement of commodity hardware, in particular the volume of storage devices and the speed of interconnect technologies used in network adapter cards and multi-core processors, it is now possible to capture 10 Gbps and beyond real-time network traffic using a commodity computer, such as n2disk. Also with the advancement of distributed file system （such as Hadoop, ZFS, etc.） and open cloud computing platform （such as OpenStack, CloudStack, and Eucalyptus, etc.）, it is practical to store such large volume of traffic data and fully in-depth analyse the inside communication within an acceptable latency. In this paper, based on well- known TimeMachine, we present TIFAflow, the design and implementation of a novel system for archiving and querying network flows. Firstly, we enhance the traffic archiving system named TImemachine＋FAstbit （TIFA） with flow granularity, i.e., supply the system with flow table and flow module. Secondly, based on real network traces, we conduct performance comparison experiments of TIFAflow with other implementations such as common database solution, TimeMachine and TIFA system. Finally, based on comparison results, we demonstrate that TIFAflow has a higher performance improvement in storing and querying performance than TimeMachine and TIFA, both in time and space metrics.

Coevolutionary Framework for Generalized Multimodal Multi-Objective Optimization

Most multimodal multi-objective evolutionary algorithms(MMEAs)aim to find all global Pareto optimal sets(PSs)for a multimodal multi-objective optimization problem(MMOP).However,in real-world problems,decision makers(DMs)may be also interested in local PSs.Also,searching for both global and local PSs is more general in view of dealing with MMOPs,which can be seen as generalized MMOPs.Moreover,most state-of-theart MMEAs exhibit poor convergence on high-dimension MMOPs and are unable to deal with constrained MMOPs.To address the above issues,we present a novel multimodal multiobjective coevolutionary algorithm(Co MMEA)to better produce both global and local PSs,and simultaneously,to improve the convergence performance in dealing with high-dimension MMOPs.Specifically,the Co MMEA introduces two archives to the search process,and coevolves them simultaneously through effective knowledge transfer.The convergence archive assists the Co MMEA to quickly approach the Pareto optimal front.The knowledge of the converged solutions is then transferred to the diversity archive which utilizes the local convergence indicator and the-dominance-based method to obtain global and local PSs effectively.Experimental results show that Co MMEA is competitive compared to seven state-of-the-art MMEAs on fifty-four complex MMOPs.

A Novel Collaborative Evolutionary Algorithm with Two-Population for Multi-Objective Flexible Job Shop Scheduling

Job shop scheduling(JS)is an important technology for modern manufacturing.Flexible job shop scheduling(FJS)is critical in JS,and it has been widely employed in many industries,including aerospace and energy.FJS enables any machine from a certain set to handle an operation,and this is an NP-hard problem.Furthermore,due to the requirements in real-world cases,multi-objective FJS is increasingly widespread,thus increasing the challenge of solving the FJS problems.As a result,it is necessary to develop a novel method to address this challenge.To achieve this goal,a novel collaborative evolutionary algorithmwith two-population based on Pareto optimality is proposed for FJS,which improves the solutions of FJS by interacting in each generation.In addition,several experimental results have demonstrated that the proposed method is promising and effective for multi-objective FJS,which has discovered some new Pareto solutions in the well-known benchmark problems,and some solutions can dominate the solutions of some other methods.
