An explainable artificially intelligent (XAI) application contains an ordered sequence of artificially intelligent software modules. When an input dataset is submitted to the application, each module generates an output dataset and an explanation that represents, as a set of Boolean expressions, reasoning by which each output element was chosen. If any pair of explanations are determined to be semantically inconsistent, and if this determination is confirmed by further determining that an apparent inconsistency was not a correct response to an unexpected characteristic of the input dataset, nonzero inconsistency scores are assigned to inconsistent elements of the pair of explanations. If the application's overall inconsistency score exceeds a threshold value, the system forwards information about the explanation, the offending modules, and the input dataset to a downstream machine-learning component that uses this information to train the application to better respond to future input that shares certain characteristics with the current input.

A radiant panel having a U-shaped channel or groove with substantially parallel vertical sides. Because varied diameter tubing pressed into curved channels of varying radius will change their shape from round to oval by different amounts, channel width will be reduced at curved channel areas as appropriate, based on tubing size and channel radius. This reduction in curved channel width compared to straight channel width allows for a consistent friction force to be developed upon pressing the tubing into a channel. The depth of groove may be varied to allow for the increased vertical dimension of tubing which is deformed from round to oval by bending forces, so that tubing can be installed consistently flush with the surface of the radiant panel. Varying width and depth will also tend to maximize the contact area of tube to conductive surface, thereby improving the flow of heat from tube to radiant panel.

Nitric oxide-releasing mesoporous silica nanoparticles (MSNs) were prepared using an aminosilane-template surfactant ion exchange reaction. Initially, bare silica particles were synthesized under basic conditions in the presence of cetyltrimethylammonium bromide (CTAB). These particles were functionalized with nitric oxide (NO) donor precursors via the addition of aminosilane directly to the particle sol, and a commensurate ion exchange reaction between the cationic aminosilanes and CTAB. N-diazeniumdiolate NO donors were formed at the secondary amines to yield NO-releasing silica MSNs. Tuning of the ion exchange-based MSN modification approach allowed for the preparation of monodisperse particles ranging from 30 to 1100 nm. Regardless of size, the MSNs stored appreciable levels of NO (0.4-1.5 μmol/mg) with tunable NO-release durations (1-33 h) dependent on the aminosilane modification. The range of MSN sizes and NO release demonstrate the versatility of this strategy.

An unmanned and self-powered vehicle or Towable Autonomous Dray (TOAD) may follow a vehicle and tow a trailer, haul a load, and/or recharge a pilot vehicle. The TOAD may be semi-autonomous and may attach to a pilot vehicle by an electronic identification. Further, wireless charging of the pilot vehicle may be provided by the TOAD. Smart trailer brakes, electric trailer axles, and a mechanically coupled tow vehicle may be provided by the TOAD in combination with additional units. A smart trailer controller may include a smart head unit and a smart tail unit in a trailer that may offer trailer security and increased safety. A smart trailer brake controller on the pilot vehicle and a smart module on the trailer may be applied where no unmanned vehicle is employed, such as, in a classic pick-up/trailer combination.

What is provided is a front end structure which can secure a strength and rigidity of a frame portion and reduce a weight thereof. The front end structure includes a frame portion (45), a vehicle body mounting portion (46), and a duct portion (42). The frame portion is formed to cover outer peripheral portions of a radiator and a condenser disposed in front of the vehicle body. The vehicle body mounting portion is provided on the frame portion and is connected to a front end of a front side frame (23) which extends in a forward and rearward direction of a vehicle body. The duct portion is continuous with the front end of the frame portion, and at least a part thereof is disposed above the vehicle body mounting portion and forms a continuous flow path between the duct portion and the condenser in a vertical direction. The frame portion, the vehicle body mounting portion, and the duct portion are integrally formed.

A wheel-mounting assembly for an agricultural utility vehicle includes a chassis and a telescopic axle arrangement fixed to the chassis. The telescopic axle arrangement includes an inner axle telescopically received in an outer axle, which is fixed to the chassis. A wheel-support assembly is mounted to an outboard end of the inner axle. A steering-control actuator is connected between the inner axle and the wheel-support assembly. The steering-control actuator is connected to the inner axle through an opening provided in the outer axle, which allows the steering-control actuator to translate together with the inner axle when track width is adjusted.

An ECU includes plural sensor units and plural control units. The sensor units include magnetic field detection elements for detecting a rotation of a motor, and output mechanical angles related to the rotation angle in one rotation and count values related to the number of rotations of the motor, respectively. One rotation of the motor is divided into indefinite regions, in which detection deviation of the count values may occur, and definite regions, in which no detection deviation occurs. The definite region of the count value is set to deviate from the definite region of the other count value. Absolute angle calculation units calculate the absolute angles using the count values of the definite regions.
