This paper is concerned with formal derivation of generalized setting (excitation) equations of the flip-flop memory elements of a sequential machine. The equations are expressed in terms of four normalized transition ...

This note is concerned with the design of fast totally self-checking checkers for m-out-of-(2m ± 1) codes. The new method uses only three levels of gates, and is based on the partitioning of the input lines into m blocks ...

This paper gives an overview of the APIM (Aristotle Parallel Inference Machine) research project, which aims to the design of a new multiprocessor architecture for the parallel execution of logic programs. The APIM system ...

The testability of modified Booth multipliers is examined with respect to the cell fault model, an implementation-independent fault model. This is especially useful in design environments where the cell realisations are ...

Τα τελευταία χρόνια της ζωής του μητροπολίτη Ναυπάκτου 'Ιωάννου Άποκαυκου καλύπτονται από ένα πέπλο που σκεπάζει αμφιβολίες και αβεβαιότητες σε τέτοιο βαθμό,, ωστε να μην εχει ξεκαθαριστεϊ πληρως, ως σημερα ακόμη, το ...

This paper proposes a new image retrieval system, thatuses only color features and it's based on a hybrid scheme which combines crisp and fuzzy techniques, in order to retrieve color based similar images. The system ...

This paper deals with the extraction of a new low level feature that combines, in one histogram, color and texture information. This feature is named FCTH - Fuzzy Color and Texture Histogram - and results from the combination ...

LIRe (Lucene Image Retrieval) is a light weight open source Java library for content based image retrieval. It provides common and state of the art global image features and offers means for indexing and retrieval. Due ...

This paper deals with a new low level feature that is extracted from the images and can be used for indexing and retrieval. This feature is called “Color and Edge Directivity Descriptor” and incorporates color and texture ...

We present a personal data management framework called Polis, which abides by the following principle: Every individual has absolute control over her personal data, which reside only at her own side. Preliminary results ...

Compact Composite Descriptors (CCD) are global image features capturing both, color and texture characteristics, at the same time in a very compact representation. In this paper we propose a combination of two recently ...

This paper presents an image retrieval suite called img(Rummager) which brings into effect a number of new as well as state of the art descriptors. The application can execute an image search based on a query image, either ...

img(Anaktisi) is a C#/.NET content base image retrieval application suitable for the web. It provides efficient retrieval services for various image databases using as a query a sample image, an image sketched by the ...

The rapid advances made in the field of radiology, the increased frequency in which oncological diseases appear, as well as the demand for prevailing medical checks, led to the creation of a large database of radiology ...

This article analyses the latency components in Mobile IPv6 handovers. It provides real-implementation results for significant parts of the handover process through measurements in a real MIPv6 implementation on a wireless ...

This paper examines the handover process of Mobile IPv6 in a real wireless testbed, based on IEEE 802.11b and extracts information on the actions taken by network entities during the movement of a mobile node. This work ...

Purpose – In order to enhance privacy protection during electronic transactions, the purpose of this paper is to propose, develop, and evaluate a personal data management framework called Polis that abides by the following ...

In this paper, a new platform, called Quantum, for distributed computations among independent agents, is presented. Quantum is capable to operate on infrastructures that are formed by massive numbers of agents communicating ...

Everyday the following question is posed: Are businesses more successful when they adapt green strategies in producing and marketing their products?. To address this issue, we should investigate to what determines the ...

We report our experiences from participating to the controlled experiment of the ImageCLEF 2010 Wikipedia Retrieval task. We built an experimental search engine which combines multilingual and multi-image search, employing ...
