Many programs require more RAM to hold their data than a typical computer has. Theoretically, both the compression and deduplication can trade the rich computing capacity for more available RAM space. This paper comprehensively evaluates the performance behaviour of memory compression and memory deduplication by using seven real memory traces. The experimental results give two implications: (1) Memory...
The Indian call center workers of a large computer manufacturer receive lower customer service ratings than their America counterparts despite superior repair outcomes. Indian call center managers are unable to bridge the gap between the customer service ratings of their Indian call centers and American call centers despite accent training and significantly more technical training. This study uses...
Due to the huge amount of calculations of video compression, its implementation needs the support of powerful computing capability. This article briefly describes the principles and key technologies of MPEG-1, and proposes an implementation method of MPEG-1 codec system based on FPGA and upper computer. The MPEG-1 encoding is implemented in FPGA, meanwhile, the adding of HDLC protocol to the compressed...
Liveness in programming environments generally refers to the ability to modify a running program. Liveness is one form of a more general class of behaviors by a programming environment that provide information to programmers about what they are constructing. This paper gives a brief historical perspective on liveness and proposes an extension of a hierarchy given in 1990, to now account for even more...
High speed carry-free adders are very important in computer arithmetic especially in decimal arithmetic where complicated operations such as division and multiplication are the bottleneck. Using redundant number systems to represent intermediate results is an efficient way to speed up decimal arithmetic units. In this paper we improve the fastest previous carry-free signed digit decimal adder, based...
Unicode font is the universally used coding system that provides a unique number of every character irrespective of the platform, program and language. The benefit of using Unicode fonts over ASCII fonts is that the Unicode fonts are visible in any computer system as well as in the web. ASCII and Unicode play the same role for English character coding system but for many languages including some major...
The elementary technology for video retrieval technique in computing is very sensitive to the user's query not to the contents of video. Every user has perspective to the video in the world of videos. So to identify this is difficult using text based video retrieval as this retrieval is based on text as processing input for video retrieval. The better approach for this video retrieval is content based...
Cloud Computing as a service-on-demand architecture has grown in importance over the previous few years. One driving force of its growth is the ever increasing amount of data which is supposed to outpace the growth of storage capacity. This way, public cloud storage services enable organizations to manage their data with low operational expenses. However, the benefits of cloud computing come along...
In order to keep an edge on enhanced competitiveness of 3G technology, the Third Generation Partnership Project (3GPP) set specific targets for the long-term evolution, including increased data rates, larger coverage footprint, and reduced latency. In combination these improvements reduce operator costs in typical traffic scenarios and also reduce overall infrastructure. This paper gives an overview...
For many people, writing is a difficult task because finding a good topic and suitable elements is just not an easy job. In this study, we put our focus on narrative creation and propose that a Picture-Attributed-Note (PAN) framework can help with writing job. Picture and attributed notes were used to present and record story elements and to stimulate creativity. The attributed notes are presented...
A number of complexity metrics has been proposed in the past. However, only a few studies have been conducted to test the relationship between those proposed complexity metrics and their applicability in the real world. To identify the effectiveness and the practicality of a metric a number of evaluation frameworks have been proposed. Out of them, the frameworks proposed by Weyuker and Briand et al...
On the study of stylistic calculation cases, under the theoretical guidance of computational linguistics, corpus linguistics, and statistics., this paper explores the definition and operating mode of computational stylistics, taking affective computing in Mansfield as a case study put forward a common mode of operation. by using Term Connection Techniques, and prove the feasibility of this mode.
Extract DTD documents rapidly by using pattern extraction method and eliminate the embedded ring in DTD by redefining the duplication name in document to solve the complex situation of which the embedded ring existed in XML document and the optimization scheme based on the interval encoding index can't solve. Map back DTD which eliminate the embedded ring to XML document, analyze XQuery query statement...
A loss less dictionary based data compression technique has been proposed in this paper which is based on the optimality of LZW code. The compression process is started with empty dictionary and if the next symbol to be encoded is already in dictionary, length of symbol code is determined by the highest symbol code in the dictionary and encoded with the code in the dictionary. Otherwise, the symbol...
In our Operating Systems course we make available in advance the lecture slides and lab sessions material. The slides are built paying attention to present the key ideas and with embedded links to sites in the Web where the topic is covered in greater detail. We also provide the corresponding excerpts of selected textbooks. Following the download activity and paying attention on what our students...
This essay applies the designing of parallel algorithm to analyse and prove that H.264 can realize parallel computing task unit selection through the research of H.264 video coding; realizes the transplantation of X264 source code based on the MPI parallel environment using the sheet ( slice ) class H.264 parallel coding calculation method; realizes the real-time coding of standard-definition video,...
This paper puts forward the function requirements of the tooth code system, and according to them describes a design that based on VC++ 6.0 and Access database. The system software can generate all the code combinations automatically according to the tooth stage head (the depth of the valleys on the key) and the number of teeth (number of the valleys) [1], and it also can remove the codes that you...
The paper proposes a Random Network Coding based solution for data dissemination applications involving multiple unicast or multicast transmissions between a source and several destinations. The solution proposed is based on a mathematical framework derived from the theory of Random Network Coding employed in multicast transmissions. This framework specifies the conditions allowing to each destination...
In this paper, a classification-based adaptive compression method for computer screen image is presented. This method firstly divides the computer Screen Image into 16x16 non-overlapping blocks, and then every block is classified into three types: text/graphic, pictorial and hybrid blocks based on the characteristics of histogram distribution and the number of colors. For complex text/graphic block,...
In order to improve the processing speed of highly complex video coding that involves high data rate and large amount of computation, a parallel video coding system optimization (PVCSO) method is proposed in this paper. By using PC cluster and general H.264 video coding standard for parallel coding experiments, the important factors that are critical to parallel coding efficiency are thoroughly examined...
