In our previous studies, the read-abortion-based role-based synchronisation (RA-RBS) and object-based synchronisation (RA-OBS) protocols are discussed to prevent illegal information flow in the role-based access control (RBAC) model. Illegal read operations mean read operations which might imply illegal information flow. Here, transactions which issue illegal read operations are aborted. In this paper, we consider a unique object whose data is not allowed to flow to another object. An illegal write is defined to be a write operation which a transaction issues after reading a unique object or illegally reading an object. Each transaction reads objects but is aborted if the transaction illegally writes an object. Two types of write-abortion (WA)-based synchronisation protocols WA-RBS and WA-OBS are discussed based on abortions of transactions issuing illegal write operations. In the evaluation, the number of transactions aborted can be more reduced in the WA protocols than the RA protocols.","PeriodicalId":383612,"journal":{"name":"International Journal of Adaptive and Innovative Systems","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126329678","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work focuses on the development of a redundant manipulator design methodology aimed at minimising the degradation in manipulator performance quality that results from k arbitrary joint failures. The relative weighted global isotropy index (RWGII) is developed for use as a manipulator design fitness metric. This metric takes into account the primary manipulation goal of maintaining kinematic dexterity, the secondary goals of collision avoidance and torque minimisation, and fault tolerance capability. The genetic algorithm search of an immense manipulator design space, conducted using the new fault-tolerant manipulator design fitness metric, yields redundant manipulator designs that effectively minimise fault susceptibility due to k joint failures while maintaining dexterous, redundancy-resolved motion on specific tasks.","PeriodicalId":383612,"journal":{"name":"International Journal of Adaptive and Innovative Systems","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122446048","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Since location information may reveal private information, preserving location privacy has become a significant issue in LBS. Many different techniques for securing location privacy have been proposed, for example, the concepts of silent period, dummy node, and cloaking region. However, much of this research has not solved the problem that the quality of service (QoS) of LBS decreases when anonymity is improved, and anonymity falls when QoS is improved. In this paper, we present a node density-based location anonymisation scheme that can provide location privacy by a hybrid method using the dummy node and the cloaking region. Especially, we propose a method to keep the anonymity without reducing the QoS of the LBS by setting the cloaking region based on the road mobility model. Simulations are conducted to evaluate our proposed method from the viewpoint of location error in LBS and the probability of tracking a target node. Simulation results show that the probability of tracking a target node by an adversary is reduced and the QoS of LBS is improved.","PeriodicalId":383612,"journal":{"name":"International Journal of Adaptive and Innovative Systems","volume":"284 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132030148","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

(2009a). An electric circuit is used in order to study the fractional behaviour and the robustness of these RLC operators and compare their responses to the behaviour of the fractance which is an ideal fractional operator (Moreau et al., 2003). This analysis is conducted for both natural and forced responses. In more details, the initial conditions of the capacitors and inductances are neglected in the first case and they are taken into consideration in the second one. The number of initial conditions is related to the number of RLC cells used. The robustness of all arrangements is analysed by varying the unsteady parameter value which is represented by an inductance in the electrical circuit. This inductance represents a different variable parameter in each field of application. For example, in the hydropneumatic domain, this inductance refers to the mass of the vehicle as the mass has the main influence on the dynamics and the robustness when designing the active suspension (Moreau et al., 2001). A conclusion will sum up the results for all four arrangements and a confirmation that the phase constancy and the robustness are present in both modes.","PeriodicalId":383612,"journal":{"name":"International Journal of Adaptive and Innovative Systems","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125165444","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
