The Gram matrix is symmetric in the case the inner product is real-valued; it is Hermitian in the general, complex case by definition of an inner product. The Gram matrix is positive semidefinite, and every positive semidefinite matrix is the Gramian matrix for some set of vectors. The fact that the Gramian matrix is positive-semidefinite can ...
Walking can help you burn calories to lose weight. Here, experts share the number of calories burned walking and how to begin a walking plan. The Number of Calories Burned Walking Might Surprise You
The energetic cost of running can be quantified through the measurement of oxygen consumption (VO2) during running at a given submaximal speed. During aerobic activities (like submaximal running), VO2 provides an indirect estimate of energy expenditure. [8]

In mathematics, a Euclidean distance matrix is an n×n matrix representing the spacing of a set of n points in Euclidean space.For points ,, …, in k-dimensional space ℝ k, the elements of their Euclidean distance matrix A are given by squares of distances between them.
Intense exercise lasting 20–45 minutes at least three time per week, or a job with a lot of walking, or a moderate intensity job. Very active 2.1 1.9 Intense exercise lasting at least an hour per day, or a heavy physical job, such as a mail carrier or an athlete in training. Extremely active 2.4 2.2
The temperature change in the water is then accurately measured with a thermometer. This reading, along with a bomb factor (which is dependent on the heat capacity of the metal bomb parts), is used to calculate the energy given out by the sample burn. A small correction is made to account for the electrical energy input, the burning fuse, and ...
