Order-batching is a common practice in orderpicking» which can reduce the total picking time if the orders have many relevant in Multi-Shuttle Warehouse System. In this paper, the performance of different order-batching methods that are made up of one seed-order selection rule and one accompanying-order selection rule is investigated. A seed-order selection rule selects the first order (i.e. the seed...
Research in the area of internet-of-things, cyberphysical-systems, and smart health often employ sensor systems at residences for continuous monitoring. Such research-oriented residential monitoring systems (RRMSs) usually face two major challenges, long-term reliable operation management and validation of system functionality with minimal human effort. Targeting these two challenges, this paper describes...
Process-aware Information Systems (PAIS) have become ubiquitous in companies. Thus the amount of data that can be used to analyze and monitor process executions is vast. The event logs generated by PAIS might contain information about decision making processes and can support the understanding and improving of procedures in companies. Mining decisions and constraints from logs has already been investigated,...
Object Tracking is an important task in Computer Vision, which has gained increasing attention from academia to industry. In this paper, we propose a real-time tracking system based on weak segmentation. Different from general tracking by detection systems, we do not classify objects into car, cat or bike, instead we just classify the image into object area and non-object area. Many tracking systems...
This paper investigates the fuzzy H∞ filter design issue for nonlinear systems with time-varying delay. In order to obtain less conservative fuzzy H∞ filter design method, a novel integral inequality is employed to replace the conventional Lebniz-Newton formula to analyze the stability conditions of the filtering error system. Besides, the information of the membership functions is introduced in the...
Cooperative caching that utilizes the distributed storage of popular files is regarded as one prospective technology for offloading the traffic for the base station (BS) and boosting the capacity of the wireless networks. It's a critical issue to achieve the goals that the content providers (CPs) are encouraged to download and cache the popular content items so that the CPs can share them with the...
Pathfinder network scaling is a graph sparsification technique that has been popularly used due to its efficacy of extracting the “important” structure of a graph. However, existing algorithms to compute the pathfinder network (PFNET) of a graph have prohibitively expensive time complexity for large graphs: O(n3) for the general case and O(n2 log n) for a specific parameter setting, PFNET(r = ∞, q...
Recommendation systems have become increasingly popular as a result of the significant growth in online information. However, it requires a substantial amount of historical user data to generate accurate predictions, which raises concerns over user privacy. Differential privacy is a well acknowledged privacy notion that has become an important standard for the preservation of privacy. Unfortunately,...
One of the key features of cloud computing is on demand resource provision. Unfortunately, different cloud service providers often have different standards, which makes the job of choosing the suitable resource to be a very difficult one for the common users. Then the technology of service broker came out which is designed to choose the appropriate services among different providers to meet the user's...
For a class of linear systems with external smooth disturbances, control design is considered to attenuate the effect of the disturbances on the outputs of the systems. To deal with the unmatched disturbances, a disturbance-dependent state transformation is introduced, so that the transformed disturbances satisfy the matching condition in the new state coordinates, and therefore we design controllers...
This paper presents a novel equivalent description of fractional-order integrals and derivatives via an auxiliary integral function of two variables. Employing the concept of Laguerre integration, a novel approximate scheme for the resulting infinite dimensional state space model is derived. A simple example with numerical simulations is provided to show the superiority and effectiveness of the proposed...

Tea is very popular in the world owing to its numerous therapeutic effects in lowering blood pressure, decreasing blood coagulation, repairing oxidative damage among many others. Due to their promising biodegradability, biocompatibility and antimicrobial activity, tea nanoparticles isolated from tea leaves have a great potential for various biomedical applications. Small molecules like polyphenols...
The finite-time tracking control for reusable launch vehicle with matched disturbance is investigated. An adaptive-multivariable controller is proposed where the bounds of the perturbations are not known. A proof of the finite-time convergence of the closed-loop system is derived using the Lyapunov technique. The feature of the proposed control scheme is that it does not require any information on...
Both the plant parameter4 and delay time of the system may vary in the time-varying system, which makes system identification relatively complex. In this paper, a new system identification algorithm based on subspace method and cross-correlation function is proposed to identify system parameter and time-delay simultaneously. The time delay is identified with the calculation of the cross-correlation...
The dual-drive H gantry is widely used in many industrial processes that require high precision Cartesian motion. The conventional rigid-link version suffers breaking down of joints if any de-synchronization between the two carriages occurs. To prevent above potential risk, a novel biaxial gantry with flexure-links is designed to allow a small rotation angle of the cross-arm. Nevertheless, the chattering...
To embed ensemble techniques into belief decision trees for performance improvement, the bagging algorithm is explored. Simple belief decision trees based on entropy intervals extracted from evidential likelihood are constructed as the base classifiers, and a combination of individual trees promises to lead to a better classification accuracy. Requiring no extra querying cost, bagging belief decision...
The problem under consideration is the axial elastic impact by a body on a thin rod. The results of theoretical, finite-element and experimental approaches to the solution of the problem are compared. The theoretical approach takes into account both the propagation of longitudinal waves in the rod and the local deformation due to the Hertz model. The results are compared with the results of three-dimensional...
Approximate message passing (AMP) is a class of efficient algorithms for solving high-dimensional linear regression tasks where one wishes to recover an unknown signal βο from noisy, linear measurements y = Αβ0 + w. When applying a separable denoiser at each iteration, the performance of AMP (for example, the mean squared error of its estimates) can be accurately tracked by a simple, scalar iteration...
At present, many human activities are influenced by the use of information technologies, undergoing major changes to adapt to them. However, in the field of education, the changes that have occurred are not enough to break with the classical learning schemes and there are lot of voices that are demanding radical changes in this context. Mainly one of the fundamental characteristics that educators...
