Why does K-means always converge? Since the algorithm iterates a function whose domain is a finite set, the iteration must eventually enter a cycle. Hence k-means converges in a finite number of iterations. Does K mean guaranteed to converge? Show that K-means is guaranteed to converge (to a local optimum). To prove convergence of the […]

What do architects need to consider when designing a building?
What do architects need to consider when designing a building? Five factors architects should consider when selecting building and flooring materials Physical Requirements. Obviously, the building materials must be functional for the intended purpose of the building. User Experience. Time and Money. Context/Setting. Upkeep. What are architects liable for? An engineer or an architect must […]
What is a developing flow?
What is a developing flow? Fully developed flow implies that the velocity profile does not change in the fluid flow direction hence the momentum also does not change in the flow direction. In such a case, the pressure in the flow direction will balance the shear stress near the wall. How do you tell if […]
What is lateral stability and how it affects the aircraft in flight?
What is lateral stability and how it affects the aircraft in flight? Lateral Stability (Rolling) Stability about the aircraft’s longitudinal axis, which extends from the nose of the aircraft to its tail, is called lateral stability. Positive lateral stability helps to stabilize the lateral or “rolling effect” when one wing gets lower than the wing […]
What is the bore on a wheel cylinder?
What is 70 dB noise level?
Which of the following is the best example of Bingham plastic?
Which of the following is the best example of Bingham plastic? Examples of Bingham plastic fluids: toothpaste, mayonnaise, chocolate, mustard. These fluids need a force to be applied before they can flow. Their viscosity doesn’t change depending of the force applied, or the amount of time the stress is exerted. Is blood a Bingham plastic? […]
What is the purpose of a pressure regulator quizlet?
What is the purpose of a pressure regulator quizlet? What is the purpose of a pressure regulator? Reduce the high cylinder or system pressure to the proper lower working pressure, it is important for the regulator to keep the lower pressure constant over a range of flow rates. What happens when a water pressure regulator […]
What is the aim of tensile test?
What is the aim of tensile test? Tensile tests help determine the effectiveness and behavior of a material when a stretching force acts on it. These tests are done under optimum temperature and pressure conditions and determine the maximum strength or load that the material can withstand. What two values are determined from a tensile […]
