There are issues with flexible DC transmission system such as a lack of control freedom over power flow. In order to tackle these issues, flow controller (DCPFC) is incorporated into multi-terminal, grid. recent years, multi-port based on modular multi-level converter has become focal point research due its simple structure and robust scalability. This work proposes model predictive (MPC) strat...

With the development of rural power market in our country, how to improve the operation more correctly and timely of power quantity collection, transmission and processing becomes a problem. The requirement of equipment in power quantity collection needs new and higher demands. The advantage of using dual-port RAM and main-spare CPU structure, when main CPU running, spare CPU supply monitoring ...

We investigate analytically and via simulations one-port circuits consisting of two bipolar junction transistors (BJT’s) and a few linear resistors connected in a feedback structure. These circuits possess topologies and parameter values such that their terminal one-port i v characteristics exhibit a negative differential resistance (NDR) region. These structures have been used in the past to m...

This paper deals with the realization of the four-pair terminal definition of impedance standards. A simple, though reliable, system is described that allows an automatic compensation of the voltage at the low potential port of impedance standards to be obtained. Such a system employs a commercial data acquisition board and a signal generator with adjustable-phase capability, which acts as the ...

The paper presents a container stacking model that simulates, solves and optimizes the container stacking activity within a fluvial or maritime port. This activity constitutes a real world problem that is omnipresent in logistic and transportation domain. Given container arrivals in a container port terminal, the objective is to assign a slot to each one in a storage area at least cost with res...

The extension and application of a queuing network model to the management of core logistic processes at the Gioia Tauro marine container terminal is presented. Real features incorporated in the model require simulation to solve it. A manager-friendly simulator is designed for the real case study, under the constraint of guaranteeing a finer representation of: the congestion phenomenon at the p...

Tannerella forsythia, a Gram-negative anaerobic bacterium, is an important pathogen in periodontal disease. This bacterium possesses genes encoding all known components of the type IX secretion system (T9SS). T. forsythia mutants deficient in genes orthologous to the T9SS-encoding genes porK, porT and sov were constructed. All porK, porT and sov single mutants lacked the surface layer (S-layer)...

We consider a port consisting of a cluster of inter-related terminals, where container vessels arrive cyclically. The problem is to strategically assign a terminal and a time interval of berthing to each of the vessels in the cycle. Restricting properties are terminal quay lengths and quay crane capacity. Conflicting objectives are i) minimizing the number of required quay cranes, ii) minimizin...

Cyber-Physical Systems (CPS) are physical systems whose operations coordinated, monitored, and controlled by computing communication functions. These typically heterogeneous, including Internet of Things information technology subsystems, can present a myriad implementation details, making them very complex systems. An important type CPS is maritime container terminal (cargo port), which facili...

Modern ports face significant challenges as strategic nodes of global supply chains, being responsible for the coordination inbound and outbound flows at deep-sea in hinterland transport corridors. Digitization adoption disruptive technologies can help to tide over operational challenges. Automated Ground Vehicles (AGVs) are an integral part operations many modern ports, especially inside conta...
