Electric motors are the largest consumer of world electric energy, consuming more than twice as much as lighting, the next largest consumer. Electric motors account for between 43 and 46% of all global electricity consumption approximately. They give rise to about 6 040 Mt of CO2 emissions. End‐users approximately spend USD 565 billion per year on electricity [1]. In recent years, increase in e...

This paper introduces the basic concept of the Position Navigation and Timing (PNT) Module as future part of a ship side Integrated Navigation System (INS). Core of the PNT Module is a sensor fusion based processing system (PNT Unit). The paper will focus on important aspects and first results of the initial practical realization of such a PNT Unit, including a realization of a Consiste...

The positivity and asymptotic stability of the descriptor time‐varying discrete‐time linear systems are addressed. The Weierstrass‐Kronecker theorem on the decomposition of the regular pencil is extended to the time‐varying discrete‐time descriptor linear systems. Using the extension necessary and sufficient conditions for the positivity of the systems are established. Sufficien...

A prototype for an operational ship routing Decision Support System using time‐dependent meteo‐oceanographic fields is presented. The control variable is ship course, which is modified using a directional resolution of less than 27 degrees. The shortest path is recovered using a modified Dijkstra’s algorithm. Safety restrictions for avoiding surfriding and...

Necessary and sufficient conditions for the asymptotic stability of positive fractional continuous‐ time linear systems with many delays are established. It is shown that: 1) the asymptotic stability of the positive fractional system is independent of their delays, 2) the checking of the asymptotic stability of the positive fractional systems with delays can be reduced to checking...

This paper presents the methodology and research results on identification of potential users of the ESABALT system, which is targeted towards improving the situational awareness in the Baltic Sea region. We describe the technique of analysing the stakeholders involved in maritime sector processes, especially in maritime transport processes, while also taking into account their differen...

Marine biology is a hybrid subject that combines aspects of organismal function, ecological interaction and the study of marine biodiversity.[1] The earliest studies of marine biology can be traced back to the Phoenicians and the Greeks who are known as the initial explorers of the oceans and their composition.[2] However, it was Aristotle (384-322 BC) who was the first to record any observatio...

Unavailability of a ship propulsion system under aging effects and proper maintenance is estimated using GO‐FLOW. GO‐FLOW is an effective software tool for the unavailability analysis of complex systems. Aging effects are incorporated into GO‐FLOW using a time‐dependent technique and assuming a linear aging model. The results show that the aging effects and improper maint...
