This study addresses the roles of self-regulation, co-regulation, and socially shared regulation in computer supported collaborative learning environment. An empirical study was conducted with 19 groups of university students working on computer virus prevention tasks. The results indicated that self-regulation, co-regulation, and socially shared regulation occurred during collaborative learning....
There is a need of noteworthy scaling down in the information approached may be saved in the most recent decade. Delicate and advanced version hard paper duplicate which helps in two ways that they increased the effectiveness from claiming data management but also improved the distribution of entrance of information. On engineered DNA, it may be a chance to view the late improvement on the possibility...
This paper presents an approach to utilize eye-tracking technology to analyze and understand complex collaborative competencies that are subsumed under the term learning to learn together (L2L2). One challenge here is to combine fruitfully analyses at different levels, ranging between gaze information, deliberate problem-solving actions, and complex collaborative interactions. Our analysis uses automated...
Cloud users store millions of files on the cloud every day. Often times the files are simply replicated so that if one is lost a mirror can be fetched when required. Simple replication of data files is easier however it is more costly since more storage is required. Alternatively, cloud datacenters use coding techniques that code a file into parts; each of which can be stored at a different location...
The emerging computational complexities arises the need of fast multiplication unit. The importance of multiplication in various applications necessitates improvement in its design so as to obtain the multiplication result efficiently. Multiplication operation can be improved by reducing the number of partial products to be added and by enhancing the adder unit for obtaining sum. The number of partial...

Content delivery networks often employ caching to reduce transmission rates from the central server to the end users. Recently, the technique of coded caching was introduced whereby coding in the caches and coded transmission signals from the central server are considered. Prior results in this area demonstrate that (a) carefully designing placement of content in the caches and (b) designing appropriate...
The classic problem for a channel with inputs X, outputs Y, and conditional probability pY |X(y|x) is to find the distribution pX(x) that maximizes Shannon's I(X; Y) subject perhaps to constraints imposed on pX(x). Here, we seek instead, for a specified pX(x), the channel pY|X(y|x) that maximizes I(X; Y) subject to constraints on pY |X(y|x). That is, we investigate the part of joint source-channel...
In this paper, we study a construction of binary switch codes. A switch code is a code such that a multi-set request of information symbols can be simultaneously recovered from disjoint sets of codeword symbols. Our construction is optimal in the sense that it has the smallest codeword length given its average encoding degree, which is logarithmic in the code dimension. Moreover, the number of queries...
A new construction for sector-disk codes and partial MDS codes up to three sector erasures are proposed. In contrast to existing codes, which are based on the design of parity check matrix, our new code is based on the design of generator matrix. This new approach allows us to construct a code that requires a small field size. In particular, for the case when there is only one sector erasure, our...
This paper presents a lossless double-precision floating point compression algorithm. Floating point compression can reduce the cost of storing and transmitting large amounts of data associated with big data problems. A previous algorithm called FPC performs well and uses predictors. However, predictors have limitations. Our program (fzip) overcomes some of these limitations, fzip has 2 phases, first...
Approximately 70% of the source code of a software system consists of identifiers. Hence, the names chosen as identifiers are of paramount importance for the readability of computer programs and therewith their comprehensibility. However, virtually every programming language allows programmers to use almost arbitrary sequences of characters as identifiers which far too often results in more or less...
Traditionally a dedicated level designer has to create every aspect of a level by hand, distribute and gather people to test it. Especially for multiplayer maps, the cyclic process of developing and testing can be quite cumbersome and time consuming. This paper presents a novel approach to provide live generation of levels for such multiplayer maps through procedural content generation and interactive...
The barcode technology has undergone many dramatic changes during the past few years. This is due to the increased need for encoding more data into the barcode. One of the latest developments in the barcode technology is color barcode, developed by Microsoft's High Capacity Color Barcode (HCCB). With four or eight colors, color barcodes are now used extensively in certain areas such as airports, print...
Space-filling curves have intrigued both artists and mathematicians for a long time. They bridge the gap between aesthetic forms and mathemtical geometry. To enable construction by computer, an efficient recursive algorithm for the generation of space-filling curves is given. The algorithm is elegant, short and considerably easier to implement than previous recursive and non-recursive algorithms,...
FASTQ is the defacto standard for data from next generation sequencing platforms. The FASTQ format uses four lines per read: two lines for header information, one for the sequence itself, and one for the quality scores. The proposed compression scheme treats the various lines of each four line set differently. The highly repetitive headers are encoded using an LZ77 variant. The reads themselves are...
This paper introduces a 2-D index map coding of the palette mode in screen content coding extension of the High-Efficiency Video Coding (HEVC SCC) standard to further improve the compression performance. In contrast to the current 1-D search using RUN to represent the length of matched string, we bring the block width and height to describe the arbitrary rectangle shape. We also use the block vector...
Fractional-pel motion compensation is very good at improving video coding efficiency, especially for camera-captured content. But for screen content, which is obtained from a computer desktop, motion vectors with integer-precision may be enough to represent the motion in different pictures. Using fractional-pel motion compensation for such content is a waste of bits. Thus, adaptive motion compensation...
Cloud computing allows users to migrate their calculations to distributed environment which will utilize more number of resources to complete execution quickly. Virtualization means multiple virtual machines (VM) on single physical machine.During process of migration, VM move one physical machine to another. In offline migration, process is stopped till the virtual machine can continue on target machine,...
Students who have studied in their native language face difficulty in acquiring programming skills through English medium instruction. One solution for this is to create screen casts of live coding along with instructor explanations in the native language. In this paper we examine the impact of screen cast based self-paced learning for Hindi medium (native language) students. Our study had three groups...
