Abstract: A dynamic viscoelastic vibration neutralizer for industrial pipes includes a metallic housing, to which the shaft supports are fixed, by screws. The supports of the viscoelastic pieces and the supports of the housing itself, allow the junction of the device with the system to be controlled. An oscillating mass, fixed in the center of a metallic shaft, is supported by the shaft supports. two sets of viscoelastic pieces, are fixed by one of their ends to the supports of the viscoelastic pieces and by the other to the oscillating mass.

The present invention may include constructing the conversational bot by training a deep learning model. The present invention may include receiving a natural language expression from a user. The present invention may include determining whether the natural language expression is enough to activate the bot.

Abstract: An example of a non-transitory computer-readable medium storing machine-readable instructions. The instructions may cause the processor to receive a three-dimensional (3D) object representation and subdivide it into a triangular grid. Curved triangles may be calculated for triangles in the triangular grid. The triangles may be subdivided and differences calculated between corresponding sections of the curved triangles and the received 3D object representation.

Abstract: A shrink film may include at least one layer comprising a blended ethylene-based polymer composition, the blended ethylene-based having a PCR content varying from greater than 5 to less than 95 wt % and a virgin resin content varying from greater than 5 to less than 95 wt %, wherein the virgin resin is selected from HOPE, LLDPE, LDPE, or combinations thereof.

Abstract: Despite recent efforts to eradicate malaria worldwide, this parasitic disease is still considered a major public health problem, with a total of 219 million malaria cases and 435,000 deaths in 2017 After a decade of use, however, resistance to CQ has emerged in some locations, including Southeast Asia, South America, and the Western Pacific region, spreading progressively into malaria-endemic areas, including Africa, where increases in malaria mortality have been observed. This has led, in recent years, to the adoption of artemisinin-based combination therapies. Artemisinin-based combination therapies remain effective in most parts of the world, but recent cases of resistance in Southeast Asia call for new approaches and especially new drugs to treat malaria. Thus, the present invention features CQ analogues of Formula (I) that exhibited high activity against CQ-sensitive and CQ-resistant blood parasites and were also active in mice.

Abstract: An example of a computer-readable medium is provided to store machine-readable instructions. The instructions may cause a processor to receive three-dimensional (3D) object representations of an object. The distance between points of a grid applied to 3D object representation and random points on the 3D object representation may provide a sampling error used in calculating a modeling accuracy between the 3D object representations.

Abstract: A method, a computer program product, and a computer system orchestrate devices of a device ecosystem. The method performed by an orchestrator includes receiving polling data from agents that are directly connected to the devices indicating simulations run by the devices for a cloud service. The method comprises determining a preview state of the device ecosystem. The method comprises determining an action to change a state of the device ecosystem based on the preview state. The method comprises generating an instruction for the action and the devices to perform the action. The method comprises transmitting the instruction to the agents, the agents actuating the change via the determined at least one of the devices performing the action. The orchestrator orchestrates the agents such that the devices are provided the cloud service isolated from a cloud computing system associated with the cloud service.

Abstract: The instant invention relates to a metallurgical furnace, comprising at least one upper stack (1), at least one lower stack (2), at least one fuel feeder positioned substantially between at least one upper stack (1) and the at least one lower stack (2), at least one row of tuyères (3, 4) positioned in at least one of the at least one upper stack (1) and at least one lower stack (2), the at least one row of tuyères (3, 4) providing a fluid communication between the inside of the furnace and the external environment, positioned in at least one of at least one upper stack (1) and at least one lower stack (2), and further comprising at least one permeabilizing fuel column fed through at least one hood (6), placed in the upper stack (1), which extends longitudinally through the furnace.

Abstract: A system and method are presented for key management and user authentication. Secure SSH access may be performed through a public/private set of SSH keys where a user uploads a public SSH key to a key management application. The private SSH key remains with a device associated with a user. The public SSH key is distributed across multiple regions to instances and is region agnostic. Public SSH keys may be distributed and synchronized in a large cloud computing environment where public SSH keys associated with users may be added or removed in order to rebuild system security.

Abstract: A method and apparatus for estimating a fouling state of a heat exchanger of an aircraft. Training sensor measurements are obtained of a parameter related to operation of the heat exchanger and a wavelet transform is applied to the training sensor measurements to obtain wavelet data. Data reduction is performed on the wavelet data to obtain representative features indicative of the training sensor measurements. A classifier is then trained to assign suitable fouling classes to the representative features. The trained classifier is used on testing sensor measurements from the heat exchanger to assign a fouling class to the testing sensor measurements in order to estimate the fouling state of the heat exchanger.

Abstract: A robotic system that includes a plurality of controlled linkages operating in an environment where random disturbance forces act on the linkages is disclosed. A rigid chassis with first and third linkages pinned to the rigid chassis at one end and pinned at the other end to other linkages is also disclosed. Sensors are also disclosed that sense the respective angles and rates of change of the angles between the chassis and the first and third linkages. Motors are also disclosed that move the first and third linkages about the pinned connections to the chassis. A controller is disclosed that controls the first and second motors as a function of the output of the sensors and a sum of the magnitudes of the discrete disturbance forces acting on the linkages to programmably control the first and second angles. The controller thereby controls the position and motion of all of the linkages without need for calculating the discrete disturbance forces acting on the individual linkages.
