To date, China has established intellectual property cooperation relationships with more than 50 partner countries and international organizations, whose goal is to create an innovation and business environment in which the value of knowledge is duly respected. “数字丝绸之路”建设亮点纷呈。共建国家加强数...
Digital transformationis the fundamental rewiring of how an organization operates. The goal of a digital transformation, as outlined in the new McKinsey bookRewired: A McKinsey Guide to Outcompeting in the Age of Digital and AI(Wiley, June 20, 2023), should be to build a competitive advantage ...
We can use the moving train thought experiment to present a simplified version of Lorentz Transformation: Bob on the ground uses the ground as his reference frame (x,ct), where x is the space coordinate and ct is the time coordinate scaled by the speed of light c. In order to simplify ...
We can check that an infinitesimal general coordinate transformation ("Einstein" transformation) δxμ=ξμδxμ=ξμ acting on the metric gives (δξg)μν(x)=(ξρ∂ρ)gμν+(∂μξρ)gρν+(∂νξρ)gρν(2.2)(2.2)(δξg)μν(x)=(ξρ∂ρ)gμν+(∂μξρ)...
Suppose we want to rotate a point (x1 y1) clockwise through an angle? about the origin of the coordinate system. Then mathematically we can show that x2 = x1cos ? + y1sin? and y2 = x1sin? – y1cos? These equations become applicable only if the rotation is about the...
In essence, the world transformation places a model into the world; hence its name. The following illustration shows the relationship between the world coordinate system and a model's local coordinate system.The world transformation can include any combination of translations, rotations, scalings, ...
While project managers may coordinate a few aspects of their project, a project coordinator’s role is more focused. A project coordinator exclusively handles the day-to-day processes. This includes managing costs, building reports for stakeholders, and reporting to the project manager (in some ins...
What is translation versus rotation? Rotation & Translation: Definition of rotation is defined using an example of a square placed in an x-y coordinate frame. Similarly, the definition of translation is defined using an example of a square placed in the x-y coordinate frame. Both are defined...
4.What is coordinate structure and what properties does it have? Some structures are formed by joining two or more elements of the same type with the help of a conjunction such as and or or. Such phrasesare called coordinate structures. Coordination exhibitsthe followfor important properties: ...
1) There is no limit on the number of coordinated categories that can appear prior to the conjunction. 2) A category at any level (a head or an entire XP) can be coordinated. 3) Coordinated categories must be of the same type. 4) The category type of the coordinate phrase is identica...
