The perceived distance between objects has been found to decrease over time in memory, demonstrating a partial failure of space constancy. Such mislocalization has been attributed to a generalized compression effect in memory. We confirmed this drift with a pair of remembered dot positions but did not find a compression of perceived distance when the space between the dots was filled with a con...

Introduction A new compression algorithm is presented which may either be considered an improvement to dictionary coding or an improvement to context coding. This algorithm works by reducing the set of available window position, for an LZ77 encoder to match from; thus fewer bits are required to indicate the match-from location, and higher compression is attained because the average match length...

The effective size of an L2 cache can be increased by using a dictionary-based compression scheme. Naive application of this idea performs poorly since the data values in a cache greatly vary in their “compressibility.” The novelty of this paper is a scheme that dynamically partitions the cache into sections of different compressibilities. While compression is often researched in the context of...

In this paper, we consider the problem of lossless compression of video by taking into account temporal information. Video lossless compression is an interesting possibility in the line of production and distribution. We propose a compression technique which is based on motion compensation, optimal 3D linear prediction and context based GolombRice entropy coding. The proposed technique is compa...

In real time applications Image Compression plays a major role in storage memory and transmission bandwidth. As many compression methods are existing, selection of compression methods depends upon the quality in image reconstruction. Two popular compression methods are Wavelet and Ridgelet methods. Wavelet method has affected by the blocking artifacts and Ridgelet is designed to handle only lin...

Roles of the extrinsic and intrinsic tongue muscles in the production of vowel /i/ were examined using a finite element model applied to the tagged cine-MRI data. It has been thought that tongue tissue deformation for /i/ is mainly due to the combined actions of the genioglossus muscle bundles advancing the tongue root to elevate the dorsum with a mid-line grooving. A recent study with the tagg...

percutaneous vertebroplasty is a promising therapeutic technique for pain control in patients with pathologic fractures of vertebral bodies. percutaneous vertebroplasty is an appropriate treatment for vertebral pathologic fractures, which is resistant to other usual treatment. it is a useful and only choice in special cases, because of less tissue damage and there is no risk of open surgery and...

We investigate the feasibility of using instruction compression at some level in a multi-level memory hierarchy to increase memory system performance. Compression eeectively increases the memory size and the line size reducing the miss rate at the expense of increased access latency due to decompression delays. We analytically evaluate the impact of compression on the average memory access time...

Evaluation of text summary is very essential issue of summarization. Normally, we can judge the relevance of any summary by applying extrinsic or intrinsic evaluation measures. Intrinsic evaluation techniques try to judge the relevance of any summary with evaluation by human experts. Extrinsic evaluation techniques judge quality of summary with task oriented techniques like task related to extr...
