Cache compression seeks the benefits of a larger cache with the area and power of a smaller cache. Ideally, a compressed cache increases effective capacity by tightly compacting compressed blocks, has low tag and metadata overheads, and allows fast lookups. Previous compressed cache designs, however, fail to achieve all these goals. In this paper, we propose the Skewed Compressed Cache (SCC), a new...
A caching model is proposed to accelerate the I/O speed between disks and FPGA devices in the conditions of reconfigurable computing. Especially the speed of FPGA processing is much larger than the RAID reading rate. The accelerating strategy is based on LRU-MRU replacement, adding physical address factors at the same time. In the case of two-cache application mode, the accelerating strategy, according...
Women represent more than 50% of the University students both in Europe and the United States. According to this, one might assume that the number of female students in Engineering might have been progressively increasing. But, the under-representation of women in engineering degrees has become a persistent problem. This work presents an analysis of women enrolment in engineering degrees at the Public...
The existing research of distributed provenance storage is at the preliminary stage. Most of the researchers are endeavor to improve the query efficiency of storage solution, whereas, very few people pay attention to the matching problem of provenance and data and the waste of storage space. Two aspects on the problem of provenance storage were proposed in this paper. First one is the relationship...
Qualitative Mapping(QM) is the basis of Property Theory, by which Conversion Degree Functions are induced. Furtherly Inverse Conversion Degree Functions are proposed used to convert qualitative description into quantitative value for some attributes of objects according to the degree to which the qualitative description belongs. Finally Qualitative Membership Degree Matrix based on the proportion...
Since adversaries may spoof their source IPs in their attacks, traceback schemes have been proposed to identify the attack source. Among these methods, Hybrid IP traceback schemes fuse packet marking and packet logging, using only one packet for traceback and reducing the storage requirements during packet logging. However, if a hybrid traceback scheme logs a packet's digests on a router, the router's...
This paper deals with information education in development of a knowledge-based society in Croatia. The basic objective of the paper is focused on systematic comprehension and analysis of the situation related to information education and its tendency. Hence, some concepts and models for IT education in Croatia were propounded. Accordingly, these tasks were fully accomplished. Application of ICT has...
Event matching is the process of checking high volumes of events against large numbers of subscriptions and is a fundamental issue for the overall performance of a large-scale distributed publish/subscribe system. Most existing algorithms are based on counting satisfied component constraints in each subscription. As the scale of a system grows, these algorithms inevitably suffer from performance degradation...
As a space-efficient approach to data archive and backup, data deduplication is becoming increasingly popular in storage systems. However, as the data growing rapidly in data centers, single-node storage node is no longer be able to provide the corresponding throughput and capacities as expected. Building deduplication clusters is considered as a promising strategy to leverage such bottle-neck on...
Out of sample fusion is a computational method where real and independent computer generated data are fused. The method hinges on a density ratio model whereby the distributions of the real and the generated data are related. The method is applied in the interval estimation of very small binomial proportions from moderately large samples.
If ubiquitous learning is to be effectively developed and feasibly applied to education, it is necessary to evaluate its effectiveness. Using fuzzy theory, the ubiquitous learning evaluation model is established in the paper. Evaluation index system is formulated which accords with ubiquitous learning and learners characteristics. Put forward subjective and objective weighting method to determine...
This paper presents a novel B-tree storage scheme that reduces the number of time-consuming erase operations on flash memory-based systems. The scheme adopts group-based round robin fashion and in-block logging technique for efficiently maintaining the B- tree nodes in the heavy-update workloads. Experimental results show that the proposed scheme improves the I/O performance by up to 3X , compared...
Education quality assessment of primary and secondary school teachers is an important part of teacher education. In this paper, a fuzzy comprehensive assessment model for the education quality of primary and secondary school teachers, which combines the experience of experts with quantitative analysis, is proposed. It reduces the influence of human arbitrariness on the assessment, and then enhances...
Certain subclasses of analytic univalent functions associated with quasi-subordination are defined and parameter estimation for functions belonging to these subclasses are derived.
Snapshot was not realized as a basic function in distributed database HBase. This paper studied on the key issues and the progress of design and realization of snapshot of distributed database HBase, realized the function that recover the HBase table to the snapshot created state through the snapshot recovery, and verified its availability by experiments.
Economies of the world are growing faster than ever. The Asian countries are also in a major play with the economic giants in the world. Stock Exchange is a key component of a country's economy. In this research we mainly focus on promoting investment of market shares. Sri Lanka being a small island in Asia seems to show a strong growth rate in the 21st Century. And its main stock exchange, the Colombo...
Software architecture design ability is quite important for a college student majored in the direction of software technology. In college education, students can be trained to elevate their software architecture design ability. In this paper, we introduce our practice in cultivating students' ability of software architecture design by means of laying solid theoretical foundation, building favorable...
This work deal with multi-functional use of electronic power converters as interface between utility grid and local power sources. The Conservative Power Theory is used to simultaneously injecting power into the grid and performing selective disturbance compensation.
China is a multi-ethnic nation with rich and diverse culture traditions. State-wide standardized textbooks, however, take little into account the local ethnic minority cultures; thus limiting the opportunities of preserving the unique ethnic traditions through education. On the other hand, property of information technology requires information technology teaching to combine knowledge with local culture...
In this paper, we propose a training model that aims to improve the college students' autonomous learning ability based on the Internet. We build an autonomous learning environment, which can effectively combine classroom teaching and extra-curricular learning without time and space constraints. In this way, it not only can evaluate the students' self-learning ability, but also classification regulation...
