SATEST : The 1997 Rotterdam Experiment on VTS Operator Performance

IFAC Proceedings Volumes, 1998
Abstract Traffic management and control systems are deployed in all modes of tranportation to ensure a safe and efficient traffic flow. In maritime transportation, traffic control is perfonned by Vessel Traffic Services (VTS). In search for optimal support for VTS operators, tools are developed constantly. A performance based measurement of situation

Prediction table to improve maritime situation awareness by VTS operator

2013 International Conference on Fuzzy Theory and Its Applications (iFUZZY), 2013
A prediction of vessels movements helps to improve safety of navigation. In an arbitrary water area, the prediction information of vessels to be encountered can be provided by observing inbound/outbound vessels for ports. This study proposes a prediction table representing leeway and arrival time at each waypoint. Given the table, the encounted vessels

The VT-operator Semigroup for Two Kinds of Regular Semigroups

Semigroup Forum, 1999
A by now standard way of studying the lattice of congruences on a regular semigroup is via various operators. This approach originated with the study of the \(T\) and \(K\) operators on an inverse semigroup: with any congruence \(\rho\) are associated \(\rho k\), \(\rho K\), \(\rho t\) and \(\rho T\), respectively the least and greatest congruences ...

Realization of 0.7-V analog circuits by adaptive-Vt operation of FinFET

IEEE Custom Integrated Circuits Conference 2010, 2010
An adaptive-threshold-voltage differential pair and a low-voltage source follower using independent-double-gate-(IDG-) FinFETs are proposed for a low-voltage operational amplifier (op amp). These circuits were implemented by our FinFET technology that enables co-integration of connected-DG- (CDG-) and IDG-FinFETs.

Organization of Vessel Traffic on Dredged Świnoujście-Szczecin Fairway: VTS Operators’ Viewpoint on the Use of Infrastructure for Ships Passing

European Research Studies Journal, 2023
DESIGN/METHODOLOGY/APPROACH: A marketing research method was used to conduct the research. A questionnaire was developed, and the survey was carried out among VTSOs employed in Vessel Traffic Services centers in Szczecin and Świnoujście.

On v-filters and normal v-filters of a residuated lattice with a weak vt-operator

Information Sciences, 2008
The properties of \(v\)-filters and normal \(v\)-filters of a residuated lattice with a weak \(vt\)-operator are investigated. Some good results are obtained.

Mechanical ventilation in the operating room: Adjusting VT, PEEP, and FiO2

Trends in Anaesthesia and Critical Care, 2012
Summary Perioperative ventilatory management is a key component of patient outcome. Ventilation with physiological tidal volume decreases pulmonary inflammatory response, intubation time, risk of re-intubation, and postoperative pulmonary complications (PPC). Atelectasis is closely related to anaesthesia, produces hypoxaemia, and increases the risk of

Bulk-driven gain-enhanced fully-differential amplifier for VT + 2Vdsat operation

2008 IEEE International Symposium on Circuits and Systems (ISCAS), 2008
A bulk-driven fully differential CMOS amplifier based on an active bootstrapped gain enhancement technique is introduced. The gain enhancement technique produces gains in excess of 100dB at supply voltages below VT + 2Vdsat in a two stage amplifier. The design constraints for obtaining maximum speed with this architecture are discussed.

Structure, organization and operation of the VTS centre in Malmö

2014
The study of the organization and efficiency of the VTS services is an important part of the sea traffic safety research. The performance of the VTS staff as well as the impact of various engineering and technological factors exercise a major influence on the efficiency of the VTS service. The study of the organizational structure of and the technology
