ELECTRONIC JOURNAL OF THE FACULTY OF ARTS, UNIVERSITY OF MISURATA: AN EVALUATION STUDY

The aim of the study was identifying the reality of the electronic journal of the Faculty of Arts at Misurata University, and knowing its compatibility with the standards of a number of databases and directories of international journals. The researcher has applied a descriptive analytical approach to compare and evaluate between what was offered in the electronic journal and the indicators mentioned in the model approved by the University of Al-Quds. According to the results of the study, it was found that, despite the journal has committed to the majority of standard indicators; there is a shortcoming in its website as it needs to be modified in a way that ensures attracting readers. In addition, the receiving date, the date of announcing the publication, and the year of issuance are not documented. Moreover, the researcher's international academic number and the document DOI have not identified in the published articles. It should also be noted that the publication in the journal has ceased since the beginning of the year (2022). A number of recommendations can be suggested which might contribute to the improvement and development of scientific research policies at the Faculty of Arts, Misurata University. First, it is recommended to initiate a scientific research plan. Secondly, it is suggested to develop the faculty members' research skills and competencies locally and internationally by participating in courses designed for this purpose. Thirdly, it is important to provide research scholarships and incentives to the faculty members for publishing their aricles in the journal. Moreover, financial rewards to refereeing committees for reviewing scientific studies can be necessary in order to ensure the continuous issuance of journal. Finally, it is significant to work on classifying and indexing scientific articles in order to make it easier for researchers to access them with less time, effort and cost

Fuzzy-Folded Bloom Filter-as-a-Service for Big Data Storage in the Cloud

With the ongoing trend of smart and Internet-connected objects being deployed across a broad range of applications, there is also a corresponding increase in the amount of data movement across different geographical regions. This, in turn, poses a number of challenges with respect to big data storage across multiple locations, including cloud computing platform. For example, the underlying distributed file system has a large number of directories and files in the form of gigantic trees, which are difficult to parse in polynomial time. Moreover, with the exponential increase of big data streams (i.e., unbounded sets of continuous data flows), challenges associated with indexing and membership queries are compounded. The capability to process such significant amount of data with high accuracy can have significant impact on decision-making and formulation of business and risk-related strategies, particularly in our current Industrial Internet of Things environment (IIoT). However, existing storage solutions are deterministic in nature. In other words, they tend to consume considerable memory and CPU time to yield accurate results. This necessitates the design of efficient quality of service-aware IIoT applications that are able to deal with the challenges of data storage and retrieval in the cloud computing environment. In this paper, we present an effective space-effective strategy for massive data storage using bloom filter (BF). Specifically, in the proposed scheme, the standard BF is extended to incorporate fuzzy-enabled folding approach, hereafter referred to as fuzzy folded BF (FFBF). In FFBF, fuzzy operations are used to accommodate the hashed data of one BF into another to reduce storage requirements. Evaluations on UCI ML AReM and Facebook datasets demonstrate the efficacy of FFBF, in terms of dealing with approximately 1.9 times more data as compared to using the standard BF. This is also achieved without affecting the false positive rate and query time.

Web directories: selected features and their impact on directory quality

Purpose – The purpose of this paper is statistical examination of nearly 7,000 web directories and an analysis of factors which affect their quality measured by PageRank. Design/methodology/approach – The authors analysed 6,821 directories registered at www.katalogiseo.info/. The following information about the directories was examined: the year of registration on the website, the directory’s PageRank value, the existence of an active IP address, backlink requests, a fee charged for submission to the directory, as well as directory moderation and subject. Statistical analyses were performed with the use of Microsoft Excel, version 2010, and R software, version 3.0.0. The PageRank values were collected with a software written in Python. Findings – The study has shown a gradual increase in popularity of directories as one of the basic tools in search engine optimisation. The analysis has indicated a relatively high percentage of spam web directories. The evidence of this is the number of directories with undetermined PageRank values. The study revealed that careful management of a directory and its subject have key impact on directory quality measured by PageRank. Originality/value – Relatively few publications focus on the problem of web directories which represent a very large group of websites created solely to manipulate web search engine rankings. This paper discusses the phenomenon of web directories, reveals the percentage of spam directories, and factors which affect their quality measured by PageRank.

Directory search performance optimization of AMGA for the Belle II experiment

AMGA (ARDA Metadata Grid Application) is a grid metadata catalogue system that has been developed as a component of the EU FP7 EMI consortium based on the requirements of the HEP (High-Energy Physics) and the biomedical user communities. Currently, AMGA is exploited to manage the metadata in the gBasf2 framework at the Belle II experiment, one of the largest particle physics experiments in the world. In this paper, we present our efforts to optimize the metadata query performance of AMGA to better support the massive MC Campaign of the Belle II experiment. Although AMGA exhibits very outstanding performance for a relatively small amount of data, as the number of directories and the metadata size increase (e.g. hundreds of thousands of directories) during the MC Campaign, AMGA suffers from severe query processing performance degradation. To address this problem, we modified the query search mechanism and the database scheme of AMGA to provide dramatic improvements of metadata search performance and query response time. Throughout our comparative performance analysis of metadata search operations, we show that AMGA can be an optimal solution for a metadata catalogue in a large-scale scientific experimental framework

ECFS: A decentralized, distributed and fault-tolerant FUSE filesystem for the LHCb online farm

The LHCb experiment records millions of proton collisions every second, but only a fraction of them are useful for LHCb physics.In order to filter out the "bad events" a large farm of x86-servers (~2000 nodes) has been put in place. These servers boot from and run from NFS, however they use their local disk to temporarily store data, which cannot be processed in real-time ("data-deferring"). These events are subsequently processed, when there are no live-data coming in. The effective CPU power is thus greatly increased. This gain in CPU power depends critically on the availability of the local disks. For cost and power-reasons, mirroring (RAID-1) is not used, leading to a lot of operational headache with failing disks and disk-errors or server failures induced by faulty disks.To mitigate these problems and increase the reliability of the LHCb farm, while at same time keeping cost and power-consumption low, an extensive research and study of existing highly available and distributed file systems has been done. While many distributed file systems are providing reliability by "file replication", none of the evaluated ones supports erasure algorithms.A decentralised, distributed and fault-tolerant "write once read many" file system has been designed and implemented as a proof of concept providing fault tolerance without using expensive – in terms of disk space – file replication techniques and providing a unique namespace as a main goals.This paper describes the design and the implementation of the Erasure Codes File System (ECFS) and presents the specialised FUSE interface for Linux.Depending on the encoding algorithm ECFS will use a certain number of target directories as a backend to store the segments that compose the encoded data. When target directories are mounted via nfs/autofs – ECFS will act as a file-system over network/block-level raid over multiple servers.

An SSD-based accelerator for directory parsing in storage systems containing massive files

Data explosion introduces new challenges to storage systems. In a file system for big data, a large number of directories and files exist, which are usually organized in a large tree. Parsing directories in a large tree is difficult. In this paper, we propose an accelerator, which helps file systems to fetch the metadata of files rapidly. Contributions of this work include two aspects. First, we propose an accelerator for directory parsing. The accelerator is actually an SSD-based (Solid State Drive-based) cache, which keeps the metadata of frequently or recently accessed files and directories. When a file is demanded, the accelerator attempts to obtain its metadata directly from SSD. If the metadata is kept in SSD, the file system can rapidly obtain the metadata. However, if the metadata is not in SSD, the accelerator consumes a long time to access SSD, but to no avail. In order to avoid non-beneficial SSD accesses, the accelerator predicts whether the metadata is kept by SSD before issuing a read request. Only if the metadata has a high probability of being kept in SSD, the accelerator issues a request to the SSD. The second contribution of this paper is a new bloom filter used to predict whether a piece of data is kept in SSD. Bloom filter is a space-efficient data structure supporting membership query. But, the standard bloom filter cannot support element deletion. Whereas, our accelerator is a cache, which evicts items periodically. The standard bloom filter is not suitable for our accelerator. In this work, we designed a new bloom filter with low overhead, which supports element deletion. The new bloom filter perfectly suits the proposed accelerator. With the prediction of our bloom filter, the accelerator can accelerate the process of directory parsing with nearly no negative impact. We evaluated the accelerator by using a prototype. Experimental results demonstrate that, the accelerator can speed up the directory parsing process by nearly four times compared with a file system without an accelerator.

차세대 이동통신 시스템에서 유동적 USIM 카드를 이용한 인증 시스템

본 논문은 유동적 USIM(Universal Subscriber Identity Module)을 이용한 사용자 편의를 위한 인증시스템을 제안한다. 유동적 USIM 카드는 이동통신망 이용자에게 시스템에서 단말의 할당된 고유번호나 주민등록번호와 같은 개인화 정보를 인증의 인자로 이용하여 제한된 횟수나 사용시간을 허가하는 인증 방법이다. 본 연구에서 제안하는 모듈을 검증하기 위해 시뮬레이션을 수행하였으며 제안한 알고리즘 및 시스템이 현재의 시스템에서 완벽하게 동작하며, 기존의 USIM 카드를 사용하는 인증방법과도 높은 호환성을 확인하였다. 또한 유동적 USIM 카드를 이용하여 또 다른 인증방식을 설계할 수도 있음을 제시하였다. 제안하는 유동적 USIM 기술을 적용할 경우 간단하면서도 강력한 인증방법과 시스템을 개발할 수 있을 것이며 사용자 환경과 독립적으로 이동통신망 접근을 가능하게 해 줄 수 있다. This paper presents a user-friendly authentication system using a flexible USIM. In the proposed method and its system, the flexible USIM utilizes personalized data such as Mobile Directory Number(MDN) and social security number as the key to user authentication. The authentication method proposed in this paper permits limited times of use and/or limited duration of use. A simple simulation model shows that the proposed algorithm works well and shows high compatibility with existing authentication methods. In addition, an alternative or more advanced authentication system can be developed with the proposed flexible USIM card. It is seen that this simple alternative method will eventually be able to make wireless communication networks more easily accessible for subscribers, irrespective of user environments.

Effect of heterogeneity on static load balance algorithm performance in DHT systems

Application layer peer to peer (P2P) network technology is widely regarded as the most important development for next generation Internet infra‐structure. For these systems to be effective, load balancing among the peers is critical. Early structured P2P systems rely on the randomness of object ID generated with a dynamic hash function to avoid the load imbalance issue. This has been known to result in an imbalance factor of O (log N) in the number of items stored at a node. This paper makes two contributions. First, based on previous work, we propose a simple yet extremely effective extension. We demonstrate the superior performance of our proposal and also explore other important issues vital to the performance for the virtual server framework, such as the effect of the number of directories employed in the system, and the performance ramification of user registration strategies. Secondly, and more significantly, we characterize systematically the effect of heterogeneity on load balancing algorithm performance, and the conditions in which heterogeneity may be easy or hard to deal with. We show how previous results may be valid only in the simpler settings.

The Server Reassignment Problem for Load Balancing in Structured P2P Systems

Application-layer peer-to-peer (P2P) networks are considered to be the most important development for next-generation Internet infrastructure. For these systems to be effective, load balancing among the peers is critical. Most structured P2P systems rely on ID-space partitioning schemes to solve the load imbalance problem and have been known to result in an imbalance factor of ominus(logN) in the zone sizes. This paper makes two contributions. First, we propose addressing the virtual-server-based load balancing problem systematically using an optimization-based approach and derive an effective algorithm to rearrange loads among the peers. We demonstrate the superior performance of our proposal in general and its advantages over previous strategies in particular. We also explore other important issues vital to the performance in the virtual server framework, such as the effect of the number of directories employed in the system and the performance ramification of user registration strategies. Second, and perhaps more significantly, we systematically characterize the effect of heterogeneity on load balancing algorithm performance and the conditions in which heterogeneity may be easy or hard to deal with based on an extensive study of a wide spectrum of load and capacity scenarios.

Systems and methods for caller-controlled tune notification of a call

A system and method for a caller to control a tune notification for a telephone call includes a service switching point and a service control point. The service switching point is operable to receive a tune notification service access code and a called directory number, and to issue a query in response to receiving the service access code. The service control point is operable to receive the query and issue a response including a tune notification signal to the service switching point. Upon receiving the response from the service control point, the service switching point processes the call so that the tune notification signal causes the tune notification to be applied to a called telephone line associated with the called directory number.

Three target document range metrics for university web sites

AbstractThree new metrics are introduced that measure the range of use of a university Web site by its peers through different heuristics for counting links targeted at its pages. All three give results that correlate significantly with the research productivity of the target institution. The directory range model, which is based upon summing the number of distinct directories targeted by each other university, produces the most promising results of any link metric yet. Based upon an analysis of changes between models, it is suggested that range models measure essentially the same quantity as their predecessors but are less susceptible to spurious causes of multiple links and are therefore more robust.

Wireless enhanced 9-1-1 service-making it a reality

Enhanced 9–1–1 (E9–1–1) service has proliferated in the U. S. wireline marketplace. Today, E9–1–1 relays the caller's location, name, and telephone directory number to the dispatch telecommunicator and provides accurate 9–1–1 call routing to the appropriate emergency dispatch center. In practice, E9–1–1 service improves the overall response time for dispatching emergency personnel to the scene. Unfortunately for wireless users, E9–1–1 has not evolved with this same level of service to support the mobile nature of wireless telecommunications. Recently, the Federal Communications Commission (FCC) developed requirements for enhanced wireless 9–1–1 service to improve this situation. These requirements are described in the Report and Order and Further Notice of Proposed Rulemaking, FCC Docket No. 94–102. The FCC has proposed a two-phase implementation timeline. Phase 1 requires that the wireless network provide the user's call-back number and the geographic area associated with the cell/sector handling the call. Phase 2 requires the caller's location to be reported with a much higher degree of accuracy. This paper presents an evolution plan that will apply state-of-the-art technology to solving today's wireless E9–1–1 shortcomings, and it discusses how E9–1–1 will lead to new service opportunities in the future.

Blazing the trail

Electronic information is proliferating at an exponential rate with limited concern for design or usability. Thousands of people yearly are adding dynamic information to the World Wide Web while hundreds of thousands more "surf" the Internet through Mosaic and other services. Periodicals, encyclopedias, and even news services are now published electronically. CD-ROM titles are replacing software on merchant shelves.Each of these forays into the electronic information frontier present opportunities and challenges. Tapping the vast reservoir of world-wide knowledge and interacting with individuals across the globe will surely richen our awareness, if not change our social and political ways of life. At the same time the frontier is expansive and largely uncharted. Finding our way is often like stumbling in the dark and knowing where we are as disorienting as the middle of a desert --- indeed, an unforgiving place to be lost in. Witness the number of Internet directories recently published. Useful, yes, however, most compensate for the Internet's inherent navigation problems.Like the pioneers who crossed the North American continent, or those who first sailed the Atlantic Ocean, we too are pioneers on the electronic information frontier. Whether as authors, blazing the trail and creating outposts of information, or as consumers in quest of knowledge, we face similar obstacles and possibilities. Too often on-line "help", the World Wide Web of hyperlinked information, or electronic periodicals are largely inaccessible, difficult to digest, and abandoned in frustration. Confronted by these large and unfamiliar volumes, users ask themselves "where am I?" and "is what I'm looking for really here?"This article describes two products where integrated design of information structure and graphic affordances ease user access and exploration. Multiple recognizable metaphors visually identify information categories, helping users create a predictable cognitive map of the information-space. Throughout the article we discuss some alternatives we explored, constraints we accommodated, and our design perspectives.This information design was commercially released by Hewlett-Packard in 1993 as part of a process management software package. The design principals were improved and reapplied in the design of Access HP --- an interactive graphical on-line information service --- made public in early 1994 and part of the World Wide Web (WWW) [1]. These product successes relied on iterative design, structured information, visual thinking --- and above all, full collaboration between information engineers and visual design professionals.As geographically disperse users increasingly access distributed hyper-information reservoirs, user-centered design becomes vitally important. Requirements for what we call the Four Axes of Information Architecture --- information affordability, applicability, accessibility, and anonymity --- must be addressed. Remembering that we're all pioneers --- both as authors and users --- on the electronic information frontier, we conclude with observations about these design considerations for professionals engaged in distributed on-line information design.

Multi-directory hashing

We present a new dynamic hashing scheme for disk-based databases, called Multi-Directory Hashing (MDH). MDH uses multiple hash directories to access a file. The size of each hash directory grows dynamically with the file size. The advantages of MDH are enhanced concurrency, improved bucket utilization and smaller total directory size than single-directory hashing. The expected utilization of MDH increases monotonically and approaches 100% as the number of hash directories increases. A variation of MDH, called Main Memory Multi-Directory Hashing (MM-MDH), is also described. MM-MDH achieves optimal search time in main memory databases. The performance of both methods is analyzed through theoretical and experimental results.

The National Technical Information Service - Working to Strengthen U.S. Information Sources

The National Technical Information Service (NTIS) is a self-supporting agency of the U.S. Department of Commerce that actively collects, organizes, and distributes technical information generated by United States and foreign governments in all areas of science and technology. There are two million titles in the NTIS permanent archives, some of which date as far back as 1945, and last year NTIS added 63,000 new titles to its collection. The entire collection is available at any time - whether a report dates from 20 years ago or last month. In addition, NTIS provides government generated computer software and computerized data files on both tape and diskette through its Federal Computer Products Center. To keep pace with technology transfer activities, the NTIS Center for the Utilization of Federal Technology licenses Federal inventions and makes them available to private industry and prepares and issues a number of publications, catalogs, and directories announcing Federal technologies and resources. In th...

A Working Research Prototype of an ISDN Central Office

This paper describes a working research prototype of an ISDN central office which demonstrates the key hardware and software elements needed for ISDN services. As such, it does not include all the normal trappings of a central office such as maintenance or non-ISDN interfaces and there is no attempt to cope with heavy traffic conditions. Details are included on the prototype central office architecture which is a distributed system, the call processing procedure's and the necessary data structures which provide basic circuit switching and a small number of advanced capabilities. These include the ability to suspend and resume calls at different line appearances, the ability of users to set their own line restrictions and move their services from one line to another, and the allowance of multiple directory number listings for terminals. Also discussed are security aspects of such line controls and commonplace call scenarios which must be considered to avoid deadlocks or incorrect processing by the call processor. Detailed presentations consider all of these aspects within the context of a real-time distributed central office software architecture.

A New Electronic Telephone Accounting System for Local Telephone Calls

Telephone switching systems provide facilities to measure subscriber usage for billing purposes. As new telephone services are offered, additional equipment is often required to appropriately measure this usage. Rate plans are being considered by telephone companies to more appropriately reflect service rendered on local telephone calls and additional equipment is required. This paper describes an electronic local message accounting system to measure local call usage which can be appliquéd to Panel, No. 1 crossbar, No. 5 crossbar, and Step-by-Step switching entities. Magnetic tape records for each local call provide: directory number of the calling party, distance to the called party, duration, and time of call termination. This information allows subscriber billing based on many and varied criteria which are established by software at the revenue accounting office. The system is presently in widespread use. The first installation occurred in January 1972, and now almost 5 percent of all telephones in the United States are served by the system.
