Time–space convergence (TSC) refers to the decline in travel time between geographical locations as a result of transportation, communication, and related technological and social innovations. TSC influences the development of cities and their economic competitiveness in regional and global economies; it...

Transportation Technology Innovation and Time-Space Convergence:The Case of Hu-Ning Corridor The dimension of time and space are compressing by the updated transportation technology. Using the case of Hu-Ning corridor,the paper presented the phenom... X Liu,J Zhou - 《Urban Development Studies》 ...
3. Space–time convergence result Let εhn be the error between the continuous solution and the fully discrete solution. Note that we have u(tn)−uhn=eh(tn)+ehn, thanks to this decomposition, Hypothesis 1.1 and Lemma 2.6 we can state our final result. Theorem 3.1 Assume that eh0=eh1...
This paper concerns the space/time convergence analysis of conservative two-step time discretizations for linear wave equations. Explicit and implicit, second- and fourth-order schemes are considered, while the space discretization is given and satisfies minimal hypotheses. Convergence analysis is done us...
This chapter deals with the design of multiple input multiple-output (MIMO) radar space-time transmit code (STTC) and space-time receive filter (STRF) to enhance moving targets detection in the presence of signal-dependent interferences, where we assume
space coordination for national energy supply could be devised as three stages: namely,local,regional and international.In 2008,for example,the average distance of fuels' movement for the whole country climbed up to 2435 km,nearly 3 folds more than that of 1980 when the time-space coordination ...
where L is the Lipschitz constant of f, and the last identity is due to the dominated convergence theorem43. To see statement 2, we first note that the negation of the signal −I provides us with $$\begin{array}{l}{{\mathrm{e}}}^{-\int\nolimits_{0}^{t}f(-I(s)){\mathrm{...
In this section, first we give definition of the modulus of continuity and then analyze the convergence of the presented method. Assume that Ω ¯ = [ − 1 , 1 ] × [ − 1 , 1 ] Ω =[−1,1]×[−1,1]. With C r ( Ω ¯ ) 𝐶𝑟(Ω ) we denote the space of...
