Recent formal models of pedagogy (Shafto & Goodman, 2008) assume that teachers provide evidence likely to increase the learner’s belief in a target hypothesis. Thus in pedagogical contexts, the learner can infer that evidence is not merely true of the concept but representative of it. If for instance, a teacher demonstrates a single function of a toy, the learner should assume that only that fu...

I recently came across an article from my residency training titled “The Seven Sins of Medicine.” Based on a 1948 lecture by Richard Asher, MD, the article proposes that, although there are a multitude of medical sins, seven are of primary importance: obscurity, cruelty, bad manners, overspecialization, love of the rare, stupidity, and sloth. Reading the article again, I wondered how these sins...

For an underwater Strapdown Inertial Navigation System/Doppler velocity log (SINS/DVL) integrated navigation system, the short-term failure of DVL may lead to loss reliable external information from DVL, which will cause SINS errors accumulate. To circumvent this problem, paper proposes a predictor based on fuzzy multi-output least squares support vector machine (FMLS-SVM) predict measurements ...

Recent events have given rise to considerations of systemic sin and how the church should respond it. This article looks at passages in Hebrew Bible which demonstrate communal character atonement. God holds whole nation responsible despite righteous individuals, often for sins individuals. Paul develops this relation between individuals groups his ecclesiology. I argue from development that res...

In this paper, an improved inertial frame alignment algorithm for a marine SINS under mooring conditions is proposed, which significantly improves accuracy. Since the horizontal alignment is easy to complete, and a characteristic of gravity is that its component in the horizontal plane is zero, we use a clever method to improve the conventional inertial alignment algorithm. Firstly, a large mis...

A new nonlinear robust filter is proposed in this paper to deal with the outliers of an integrated GPS/SINS navigation system. The influence of different design parameters for H∞ cubature Kalman filter is analysed. It is found that when the design parameter is smaller, the robustness of the filter is stronger. However, the design parameter is easily out of step with the Riccati equation and the...

The maneuver characteristic of the most commonly used AUV integrated navigation systems was investigated in this paper. After analyzing the error cause of conversional used Kalman filter of SINS/DVL integrated navigation systems in maneuver state, a novel method was proposed which is to use the output of complex navigation systems to revise the SINS in real-time, and an improved adaptive Kalman...

A steel plate bonded with lead zirconate titanate (PZT) actuators was studied on the basis of finite element methods (FEMs). The damping amplitudes of this plate bonded with PZT actuators were obtained at different locations and under different control conditions by analyzing the distribution of the PZT plate’s strain tensor in the first 4 modes. Furthermore, to reduce the unwanted disturbance ...
