We propose delayed choice experiments carried out with macroscopic qubits, realised as macroscopically-distinct coherent states $|\alpha\rangle$ and $|-\alpha\rangle$. Quantum superpositions of $|-\alpha\rangle$ are created via a unitary interaction $U(\theta)$ based on nonlinear Hamiltonian. Macroscopic delayed-choice give compelling reason to develop interpretations not allowing retrocausalit...

Wheeled mobile robots (WMRs) can navigate in uncontrolled environments with the assistance of electronic or physical devices. Several works have been conducted on control and management path-tracking a vehicle different road scenarios. This paper aims to create an asynchronous finite state law for WMR. The is based proportional–integral–derivative controller, performance proposed model evaluate...

In the last years, mobile robot localization has been developed significantly due to need for accurate solutions determine position and orientation of wheeled (WMR) in a given environment. Many different sensors have used solve problem. For instance, ultrasonic sensors, laser, or infrared are also pose WMR. However, sensitive noise measurements disturbances, which can distort acquired informati...

This paper presents application of the combination mapping, image identification, and indoor navigation for omnidirectional wheeled mobile robot (WMR). The mapping part uses point clouds converted from depth map LiDAR camera to construct 3D cloud map. Combining this with You Only Look Once ver.4 (YOLOv4) network, door number doorknob can be displayed on by identification. applies map, image, an...

The major cause of powdery mildew in melons (Cucumis melo L.) is the fungus Sphaerotheca fuliginea. There are several cultivar- and season-specific races of this fungus. In order to control powdery mildew, it is important to introduce resistance to fungal infection into new cultivars during melon breeding. Haploid breeding is a powerful tool for the production of pure lines. In this study, it w...

Short substrings of genomic data that are responsible for biological processes, such as gene expression, are referred to as motifs. Motifs with the same function may not entirely match, due to mutation events at a few of the motif positions. Allowing for non-exact occurrences significantly complicates their discovery. Given a number of DNA strings, the motif recognition problem is the task of d...

This paper deals with optimal temporal-planning of wheeled mobile robots (WMRs) when navigating on predefined spatial paths. A method is proposed to generate a timeoptimal velocity profile for any spatial path in static environments or when mobile obstacles are present. The method generates a feasible trajectory to be tracked by fully exploiting velocity, acceleration and deceleration boundarie...

With the widespread use of wheeled mobile robots (WMR) in various applications, new challenges have arisen in terms of designing its control system. One of such challenges is caused by wheel slippage. This paper proposes a new method for haptic teleoperation control of a WMR with longitudinal slippage (not including sliding). In this teleoperation system, the mobile robot’s linear velocity foll...

A new approach from the game-theoretic point of view is proposed for the problem of optimally combining classifiers in dichotomous choice situations. The analysis of weighted majority voting under the viewpoint of coalition gaming, leads to the existence of analytical solutions to optimal weights for the classifiers based on their prior competencies. The general framework of weighted majority r...

In this paper, we have highlighted the importance of the WMR model for designing control strategies. In this sense, the differential model has been used as reference model in order to design the control algorithm. After the control has been design, new actions will be generated for each additional wheel of the real vehicle (non-differential model). This new approach simplifies the overall contr...
