This paper proposes a new ASIFT hardware architecture that processes a Video Graphics Array (VGA)-sized (640 × 480) video in real time. The previous ASIFT accelerator suffers from low utilization because affine transformed images are computed repeatedly. In order to improve hardware utilization, the proposed hardware architecture adopts two schemes to increase the utilization of a bottleneck hardware module. The first is a prior anti-aliasing scheme, and the second is a prior down-scaling scheme. In the proposed method, 1 × 1 and 0.5 × 1 blurred images are generated and they are reused for creating various affine transformed images. Thanks to the proposed schemes, the utilization drop by waiting for the affine transform is significantly decreased, and consequently, the operation speed is increased substantially. Experimental results show that the proposed ASIFT hardware accelerator processes a VGA-sized video at the speed of 28 frames/s, which is 1.36 times faster than that of previous work.

Abstract This paper presents a synchronic and diachronic computer corpus of Makarska littoral dialects. This corpus was created as part of the project to explore the ikavian neoštokavian dialects of the narrow coastal area in Croatian region of Dalmatia around the town of Makarska. The dialectological characteristics of the dialects studied are briefly presented first, followed by presentation of the digital system. The system is logically organized in first part as a corpus of literary texts created from 1729 to 1803 and digitally processed, and in the second part from the materials collected through dialectological questionnaires prepared and methodologically adapted as part of the creation of the Croatian Linguistic Atlas. Methods of collecting linguistic data, method of input into the digital form and methods and possibilities of data processing will be explained. Based on the input and search strategies within the system, the examples will prove the origin of the dialects of the Makarska littoral to be that of the ikavian neoštokavian dialect described in the dialectological literature. This computer-based principle of work is a novelty in Croatian dialectology which has not been digitally processed so far and offers a basis for future dialectological research. This platform can be used in order to shorten the time of data processing and to analyse them more systematically and more efficiently. So far, there has been no such digital repository for any Croatian speech. This project represents a thorough synchronic and diachronic study of one rounded language area.

The paper gives a report on the Karolinska Hospital Information System in three parts.In part I, the information problems in health care delivery are discussed and the approach to systems design at the Karolinska Hospital is reported, contrasted, with the traditional approach.In part II, the data base and the data processing system, named T1—J 5, are described.In part III, the applications of the data base and the data processing system are illustrated by a broad description of the contents and rise of the patient data base at the Karolinska Hospital.
