Maritime shipping necessitates flexible and cost-effective port access worldwide through the global network. This paper presents an efficient method to identify major communities, analyses network connectivity of based on community structure. The is represented by a signless Laplacian matrix which can be decomposed generate its eigenvectors corresponding eigenvalues. largest gaps between eigenvalues were then used determine optimal number communities within eigenvalue decomposition offers...

The methods to evaluate the robustness of a network have been extensively studied. Such often require obtaining traffic equilibrium conditions or solving mathematical problems, and these can only be applied limited size. On other hand, nowadays detail road data downloaded freely, such may provide different insights on evaluation. This paper applies capacity-weighted eigenvector centrality method identify strongly weakly connected parts large networks. is one evaluation based topology with...

Anonymous communication is desirable for personal, financial, and political reasons. Despite the abundance of frameworks constructions, anonymity definitions are usually either not well defined or too complicated to use. In between ad-hoc specific protocols which sometimes only provide weakened guarantees. This paper addresses this situation from perspectives syntax, security definition, construction. We propose simple yet expressive syntax definition anonymous communication. Our covers with...

The 21st Century Maritime Silk Road (MSR) initiated by China involves the construction of a new form regional economic cooperation between and associated countries. Priority is given to eliminating maritime bottlenecks improving connectivity in shipping network along MSR. However, such potential have rarely been quantitatively identified. In this paper, we present recursive spectral bi-partitioning method detect container This identifies locating cuts with least total link frequency,...

This paper proposes a novel method to address the ferry network design problem (FNDP). Ferry transport is an increasingly important component of public transport, providing mobility for people in large cities with harbours or rivers. It therefore that networks are well designed. The connections between stations and locations hubs optimal passengers revealed by maximum passenger utility spanning tree connecting all stations. harnesses equivalence entropy maximisation find which connects A...

The ability to regulate myocardial blood flows (Q) in accord with changing O2 needs may be depressed sepsis. This could an important concern when sympathomimetics are used augment systemic oxygen delivery (QO2) this syndrome as increased accompany infusion of class drugs. Therefore after measuring the effect sepsis on metabolism, we then infused various evaluate sepsis+sympathomimetic interaction QO2. We measured Q left (LV) and right (RV) ventricles by radioactive microsphere technique 36...

A consequence of the pandemic was significant disruption to global container flows from 2020 2022, with cargo time spent in containers, ship congestion ports, and dwell times terminals all peaking during this period. After reviewing 2021 data for trans-Pacific trade lane, paper presents a system dynamics model that explains how these factors are related each other. The highlights importance speed which containers loaded unloaded ships terminals, rollovers (containers left behind). It is...

This paper describes the background and actual circuit designs in development of 48-channel modified duobinary PCM line repeater. The reasons for choice coding technique are explained. equalization requirement signal terms channel roll-off factor is obtained by considering crosstalk penalty, intersymbol interference, ease hardware implementation. implementations various repeater sections-equalization, clock recovery, data regeneration-are outlined. main considerations design size, power...
