Muscle strength further decreases with aging and make feeling burden when standing from chair. Also, people who are suffering from secondary symptoms such as bedsores and keep sitting in a chair for a long time are on the rise. The most burdensome for elderly persons when trying to stand up from the chair is to bear the weight themselves. In this paper, we introduce 'Rakutateru' which is especially designed to support elderly persons to easily stand up from the chair and keep people to more active and independent. We also evaluate the validity of an assist unit which is contained inside the lower part of the Rakutateru surface.","PeriodicalId":360794,"journal":{"name":"Int. J. Reason. based Intell.

Modern moving objects, both manned and unmanned, utilise computers as their 'onboard brain'. Since planes, spacecraft, cars, trucks and trains must demonstrate flexible and safe behaviour in various situations, it seems prospective to use intelligent control means instead of rigid control logic dispersed in a program source code. This article is concerned with the possible implementation of onboard intelligence. In contrast to the popular use of neural networks, the logic-based approach is based on clear and exact control rules with strict responsibility. Thus, formal specification and verification methods can be utilised. The article describes the real-time control algorithm logic (RTCAL) for the above-mentioned purposes. We also present case studies of reasoning at the design and operation stages for providing the fault tolerant control of a spacecraft.","PeriodicalId":360794,"journal":{"name":"Int. J.

The false data detection with conventional methods are incapable to detect some false measurements, to remedy this, we have opted to use machine learning which we used five classifiers to conceive an effective detection [k-nearest neighbour (KNN) algorithm, random trees, random forest decision trees, multilayer perceptron and support vector machine]. Our analysis is validated by experiments on a physical bus feeding system performed on PSS/in which we have developed a dataset for real measurement. Afterward we worked with MATLAB software to construct false measurements according to the Jacobean matrix of the state estimation.

Historical return data for six asset classes are used to calculate the optimal proportions of assets, included in a portfolio, so that the expected return of each asset is no less than in advance given target value. Optimisation procedure is performed at the first stage, in order to select a limited number of assets among a large assets sample. At the second stage the optimal proportions of selected assets in the portfolio are calculated, minimising a risk objective function for a given rate of return. Ten optimisation problems are solved for different expected rate of return. The optimisation is performed in MATLAB. The proposed approach is robust and could be used successfully to solve large-scale portfolio optimisation problems.","PeriodicalId":360794,"journal":{"name":"Int. J. Reason. based Intell.

These systems generate the recommendations of items in one of two ways, namely collaborative or content-based filtering. Collaborative filtering is a technique used by recommender systems in order to suggest to the user a set of items based on the opinions of other users who share with him the same preferences. One of the key issues in collaborative filtering systems (CFSs) is how to generate adequate recommendations for newcomers who rate only a small number of items, a problem known as cold start user. Another interesting problem is the cold start item when a new item is introduced in the system and cannot be recommended. In this paper, we present a clustering-based approach SCOL that aims to alleviate the cold start challenges; by identifying the most effective opinion leaders among the social network of the CFS. SCOL clustering focuses on the credibility and correlation similarity concepts.","PeriodicalId":360794,"journal":{"name":"Int. J. Reason. based Intell.

Optimisation of energy consumption has become crucial, and energy is considered a critical resource, so it is important to know and understand both how energy is measured and consumed on mobile devices. An accurate knowledge will allow us to develop efficient solutions to reduce energy consumption in order to improve the user experience. In this paper, we propose an experimental methodology to build a model of the energy consumption of mobile applications. Based on precise measurements, we elaborate predictive models of energy consumption for both unconnected and connected applications.","PeriodicalId":360794,"journal":{"name":"Int. J.

The introduced approach and the widely accepted TCO standard are compared each other and discussed. This comparison shows that the well-known magnetic field measurement TCO standard has important limitations and disadvantages. In fact, the new reasoning-based approach obtains measurement results of the extremely low frequency magnetic field which are closer to the working conditions of the portable computers' users. Accordingly, the introduced measurement methodology is more user-centric than the TCO standard measurement and should be employed in a future standardisation.","PeriodicalId":360794,"journal":{"name":"Int.

It is found that the four indexes of improved algorithm have better effect on the precision of information mining than before, and the cost of this method has not increased significantly.

Depending upon physical nearness and peer interest peers are clustered in current work. File replication algorithm has been employed that creates replicas for the requested file to enhance the efficiency. Compared to unstructured P2P the efficiency is high for structured P2P which is difficult to analyse because of their rigid topology. We have developed nearness and interested cluster (NIC) super peer network to improve the efficiency of file location in current years for P2P system but few works rely on peer interest and physical nearness. Various methods have been used to improve intra-sub-cluster searching. Here the interest is categorised into sub-interest then they are linked according to common-interest. File searching delay is minimised where an overlay is built to link. Flower filter is employed to enhance the efficiency and reduce the overhead. On comparing nearness sensible I-clustered system with other system the efficiency has been traced. The effect of enhancing the efficiency using intra-sub-cluster searching is observed in experimental results.","PeriodicalId":360794,"journal":{"name":"Int. J. Reason. based Intell.

WOA may occasionally converge to suboptimal solutions because of the loss of diversity in its population of candidate solutions. The island model is a distributed approach that is commonly used to control the population diversity in evolutionary algorithms. This paper introduces an improved version of WOA namely island-based whale optimisation algorithm (iWOA) that incorporates the island model into WOA. The iWOA algorithm was compared to well-known optimisation algorithms using 18 standard benchmark functions. The simulation results indicate that iWOA improves the accuracy of results compared to WOA and other popular evolutionary algorithms. In addition, the sensitivity analysis of iWOA to its parameters indicates that its convergence behaviour is sensitive to the parameters of the island model.","PeriodicalId":360794,"journal":{"name":"Int.
