Economic Spatial Structure in China: Evidence from Railway Transport Network

This study analyzes the structure of China’s overall railway transport network and its sub-networks of conventional railway and high-speed railway, with the aim to understand the country’s economic spatial structure that is reflected by or underlines the railway transport network. First, the results indicate that compared with developed cities, backward cities not only have fewer train services but also lack a symmetrical transport plan; backward cities tend to connect with developed cities rather than within themselves. Second, the national-level urban hierarchy was established using the proposed algorithm, which helped reveal the economic geography of three economic plates in China. Third, the law of the primate city is not prominent in a large country such as China, which is undergoing regional restructuring with the economic center of gravity shifting to the coastal area while also moving south.

Subspace Detours Meet Gromov–Wasserstein

In the context of optimal transport (OT) methods, the subspace detour approach was recently proposed by Muzellec and Cuturi. It consists of first finding an optimal plan between the measures projected on a wisely chosen subspace and then completing it in a nearly optimal transport plan on the whole space. The contribution of this paper is to extend this category of methods to the Gromov–Wasserstein problem, which is a particular type of OT distance involving the specific geometry of each distribution. After deriving the associated formalism and properties, we give an experimental illustration on a shape matching problem. We also discuss a specific cost for which we can show connections with the Knothe–Rosenblatt rearrangement.

Thinking Together and Governance in Transport Planning

Sustainability issues challenge most conventional approaches to policy design and implementation. One broader concern is how to create the conditions for the desired sustainability options to be realized. In this pursuit, policy design has several tasks to accomplish, such as strengthening governance, promoting learning, and enabling self-organization. The case study presented in this paper is an example of this undertaking. It is part of activities carried out at IRES Piemonte for supporting the sustainability-oriented transport plan of the Piedmont region in Italy. It deals with the development of an ICT tool to address the following question: given the list of the transport plan’s interventions which ones are more likely to be a successful package and achieve the desired goals most effectively? The paper outlines the conceptual and methodological underpinnings of the tool and illustrates the main results of an application which involved participants from different regional departments.

Optimal transport maps on Alexandrov spaces revisited

We give an alternative proof for the fact that in n-dimensional Alexandrov spaces with curvature bounded below there exists a unique optimal transport plan from any purely $$(n-1)$$ ( n - 1 ) -unrectifiable starting measure, and that this plan is induced by an optimal map. Our proof does not rely on the full optimality of a given plan but rather on the c-monotonicity, thus we obtain the existence of transport maps for wider class of (possibly non-optimal) transport plans.

The NOC Architecture assumes urgent part while planning correspondence frameworks intended for SOC. The NOC engineering be better over traditional transport, mutual transport plan , cross bar interconnection design intended for on chip organizations. In a greater part of the NO C engineering contains lattice, torus or different geographies to plan solid switch. In any case, the greater part of the plans are neglects to advance a Quality of Service, blocking issues, cost, Chip as well as mostly plan throughput, region transparency with inactivity. Proposed plan we are planning a reconfigurable switch for network on chip plan that improve the correspondence performance. The proposed configuration dodges the restrictions of transport based interconnection plans which are frequently applied in part progressively reconfigurable FPGA plans. . With the assistance of this switch plan we can accomplish low inactivity and high information throughput.

Transportation Planning with Minimal Costs

In this paper, the classical problem of optimal transport plan is considered taking into account the capacity of certain sections of the transport network. Let vpq units of goods be delivered from point p to point q. At thesame time, each section of the transport network has a limited capacity, which is expressed in a certain volume of goods that can be passed through it per unit of time. The goal is to distribute goods flows along different routes in such a way that all transport needs are completely satisfied, the roads are not overloaded, and at the same time the total transport costs (for example, in the form of fuel consumption,time costs, etc.) reach their minimum. It should be noted that without restrictions on capacity, the task is solved trivially: it is necessary to distribute all transportation from point p to point q on the shortest route. To solve this problem, a mathematical model of the transport network is formulated. It is proposed to reduce the solution of the this problem to the solution of the linear programming problem. As a result, we propose an algorithm for planning transportation in such a way that the total costs will be the lowest. In addition, one of the algorithm steps required solving the problem of finding the k-th path along the length between 2 nodes. To solve this problem, the corresponding algorithm is proposed. This algorithm is recursive.
