TL;DR: In this paper, the authors proposed a system for customized crowd-sourced update and validation of self-driving vehicles based on a technical computing environment (TCE)-based engine that receives user information from one or more user devices, executes a TCE model with the user information to generate behavior data of the TCE, and generates a software update for the model based on the behavior data.
Abstract: Technologies for customized crowd-sourced update and validation include a computing device having a technical computing environment (TCE)-based engine that receives user information from one or more user devices, executes a TCE model with the user information to generate behavior data of the TCE model, and generates a software update for the TCE model based on the behavior data. The TCE model may be a model for an autonomous system such as a self-driving vehicle, and the software update may be a safety update for the autonomous vehicle. The user information may include sensor data, such as distance detection sensor data. The computing device may transmit an incentive such as a software update, feature update, or safety software update to the user devices. The computing device may also receive information associated with the TCE model from one or more developer devices. Other embodiments are described and claimed.

TL;DR: By introducing an additional state feedback into a three-dimensional autonomous chaotic attractor Lu system, this article presented a novel four-dimensional continuous autonomous hyper-chaotic system which has only one equilibrium.
Abstract: By introducing an additional state feedback into a three-dimensional autonomous chaotic attractor Lu system, this paper presents a novel four-dimensional continuous autonomous hyper-chaotic system which has only one equilibrium. There are only 8 terms in all four equations of the new hyper-chaotic system, which may be less than any other four-dimensional continuous autonomous hyper-chaotic systems generated by three-dimensional (3D) continuous autonomous chaotic systems. The hyper-chaotic system undergoes Hopf bifurcation when parameter c varies, and becomes the 3D modified Lu system when parameter k varies. Although the hyper-chaotic system does not undergo Hopf bifurcation when parameter k varies, many dynamic behaviours such as periodic attractor, quasi periodic attractor, chaotic attractor and hyper-chaotic attractor can be observed. A circuit is also designed when parameter k varies and the results of the circuit experiment are in good agreement with those of simulation.

TL;DR: An autonomous platform for exploration and navigation within networks of tunnels, as those typically found in underground mines and caves, is described, allowing two modes of operation: exploration/surveying mode and autonomous navigation mode.
Abstract: This paper describes an autonomous platform for exploration and navigation within networks of tunnels, as those typically found in underground mines and caves. In this context, we propose a system allowing two modes of operation: exploration/surveying mode and autonomous navigation mode. In the exploration mode, a remotely located supervisor instructs the platform to move through successive sections of the network, gathering range data that is then concatenated into 2D/3D survey maps of the environment. In the navigation mode, the supervisor specifies high-level missions on the previously acquired survey maps. A motion planner then translates each mission into a set of consecutive navigation actions, separated by natural landmarks. Mission execution consists of autonomously detecting landmarks, self-localizing and performing the planned navigation actions. Advanced and innovative features, mostly related to exploration capabilities, navigation mode switcher, and the integrated aspect of our system distinguish it from the systems described in the literature.

TL;DR: In this article, an autonomous sensor system with low power electronics for RF communication and with an energy harvesting module is presented for temperature measurements, but it can be used with other sensor types to measure different quantities.
Abstract: Autonomous sensing system is a promising approach in applications that do not allow cabled solutions and the use of battery has maintenance problems. In this paper an autonomous sensor system with low power electronics for RF communication and with an energy harvesting module is presented. The sensored system is proposed for temperature measurements, but it can be used with other sensor types to measure different quantities. When the autonomous sensor is placed on a heat source, a thermoelectric module harvests energy, powering the autonomous sensor. In this condition no external electromagnetic field is necessary, the temperature measurement is performed and the data are saved in non-volatile memory. When the readout unit is active the electromagnetic field is used to power the autonomous sensor system and to communicate the data. An experimental set-up has been arranged to compare the temperature data of the heat source collected by the autonomous sensor and a referenced thermoresistance. The experimental measurements shows good agree between the two measured temperature data. The wake-up signals demonstrate that the autonomous system works correctly for a temperature gradient of less than 9degC, and with a readout distance of few centimeters. The presented autonomous sensor system can be efficiently used for measurements into close environment in which a temperature difference is present.

TL;DR: The paper considers a fish school as an autonomous decentralized system and constructs a mathematical model for the autonomous decentralized mechanism and a remarkable difference in fish trajectory is found between the two schools.
Abstract: The behaviour of a fish school is considered an interesting phenomenon because a fish school behaves differently in various situations. The paper considers a fish school as an autonomous decentralized system and constructs a mathematical model for the autonomous decentralized mechanism. Simulation results show that, by varying the quantity of information exchange among members in school, the present model describes fish behaviour not only for a school with fixed configuration but also for that with variable form. Furthermore, a remarkable difference in fish trajectory is found between the two schools.
