A two‐layer cryptographic scheme for a service framework based on mobile agents

Abstract

In recent years, a new computation model, referred to as Service‐On‐Demand, has come into being gradually. This concept can be summarized as: the whole Net is a computer and one can have his/her tasks served using resources scattered around the Net. One technique that uses a similar concept is Web Service, which has been applied to many networks. However, Web Service is still confined to the Client‐Server paradigm and, in our opinion, does not wholly tally with the spirit of Service‐On‐Demand. Besides, there have not been many effective security schemes proposed for Web Services. This paper presents a mobile agent service framework, designed in reference to the service‐on‐demand concept, for the next generation of service‐based Internet applications. A two‐layer cryptographic security infrastructure is laid in the service framework to offer secured services. By separating the service functionality from its operating medium, the framework successfully prevents many security problems from happening. It also offers a most desirable benefit to both service providers and users. For service providers, deployment of a service is as easy as inserting a plug‐n‐play interface card and for service users, using a service is as easy as filling out a downloaded form. The main goal of this framework is to offer a total solution for providing secured services easily instead of doing difficult programming for services.

Mind systems imitation and emulation framework for service design and production

Knowledge creation and knowledge are the primary sources of productivity, profitability and company growth in the twenty-first century. Our approach is to use brain-based metaphors and models to better understand what kind of services we should be able to design and produce now and in the future. We propose new kind of services that will be able to imitate, emulate and support the mind structures of individuals, groups, teams, companies and organisations in dynamic business situations. The services should support human memory systems, motivational systems, interpreting systems and automatic systems and their sub-systems as they are actively present in living human systems. We have named our approach as Mind Systems Imitation and Emulation Framework. Different engineering disciplines will be jointly responsible for developing and applying such services now and in the future. As an example, a Democratic Company Culture tool Accord is described.

Fuzzy C means integrated with spatial information and contrast enhancement for segmentation of MR brain images

This paper proposes a fully automated method for MR brain image segmentation into Gray Matter, White Matter and Cerebro‐spinal Fluid. It is an extension of Fuzzy C Means Clustering Algorithm which overcomes its drawbacks, of sensitivity to noise and inhomogeneity. In the conventional FCM, the membership function is computed based on the Euclidean distance between the pixel and the cluster center. It does not take into consideration the spatial correlation among the neighboring pixels. This means that the membership values of adjacent pixels belonging to the same cluster may not have the same range of membership value due to the contamination of noise and hence misclassified. Hence, in the proposed method, the membership function is convolved with mean filter and thus the local spatial information is incorporated in the clustering process. The method further includes pixel re‐labeling and contrast enhancement using non‐linear mapping to improve the segmentation accuracy. The proposed method is applied to both simulated and real T1‐weighted MR brain images from BrainWeb and IBSR database. Experiments show that there is an increase in segmentation accuracy of around 30% over the conventional methods and 6% over the state of the art methods.     

A bioinspired path planning approach for mobile robots based on improved sparrow search algorithm

In this paper, a bioinspired path planning approach for mobile robots is proposed. The approach is based on the sparrow search algorithm, which is an intelligent optimization algorithm inspired by the group wisdom, foraging, and anti-predation behaviors of sparrows. To obtain high-quality paths and fast convergence, an improved sparrow search algorithm is proposed with three new strategies. First, a linear path strategy is proposed, which can transform the polyline in the corner of the path into a smooth line, to enable the robot to reach the goal faster. Then, a new neighborhood search strategy is used to improve the fitness value of the global optimal individual, and a new position update function is used to speed up the convergence. Finally, a new multi-index comprehensive evaluation method is designed to evaluate these algorithms. Experimental results show that the proposed algorithm has a shorter path and faster convergence than other state-of-the-art studies.The full text can be downloaded at https://link.springer.com/article/10.1007/s40436-021-00366-x

Quality in patent information retrieval – Communication as the key factor

The perception of what constitutes the key quality factor of a patent search varies considerably, depending on the customers’ background and intended use of the search results. A distinction can be made between what may be termed intrinsic quality as a measure of the search process and its environment combined with the searcher’s skills and extrinsic quality, which aims to define the usefulness of the results for the customer. Intrinsic and extrinsic quality factors all require an intensive and on-going communication between the searcher and the customer: quality can only be achieved through partnership.
