Quasi-resonant DC-link voltage inverter with enhanced zero-voltage switching control
PublicationA new topology modification of the parallel quasi-resonant circuit for a dc-link voltage inverter enables regulation of the zero voltage dc-link subperiods and the dc-link voltage gradient settings. The proposed circuit is based on four MOSFET switches with free-wheeling diodes for controlled quasi-resonant recharging between L-C tank in order to assure inverter zero voltage switching (ZVS) conditions. Design optimization of the...

Chatter Vibration Surveillance by the Optimal-linear Control of Spindle Speed and Randomly Varying Spindle Speed
PublicationW artykule opisano dynamikę procesu skrawania smukłym frezem kulistym. Jako metodę nadzorowania drgań chatter zastosowano zmienną prędkość obrotową wrzeciona. Jest ona dobierna z wykorzystaniem energetycznego wskaźnika jakości co prowadzi do optymalno-liniowego sterowania prędkością obrotową. Dodatkowo zastosowano nadzorowanie drgań chatter poprzez losowo zmienną prędkość obrotową.

A concept of drive and control system of a novel device for people evacuating from large passenger ships
PublicationRosnąca z roku na rok liczba oraz wielkość i szybkość pasażerskich statków morskich wymusza szukanie nowatorskich lub doskonalenie dotychczasowych metod bezpiecznej ewakuacji ludzi z tak dużych obiektów. W artykule zaprezentowano koncepcję jednej z takich oryginalnych metod, w której między innymi, zastosowano wyciągi łańcuchowe do utrzymywania na czas rejsu oraz do opuszczania w razie ewakuacji łodzi ratunkowych. Przedstawiono...

A frequency-domain surveillance of the robot's structural vibration with a use of modal control at energy performance index
PublicationRozważano drgania niestacjonarnego układu nośnego robota IRb-6. W celu nadzorowania drgań zastosowano algorytm sterowania modalnego przy energetycznym wskaźniku jakości w dziedzinie częstotliwości. Podejście takie umożliwia wykorzystanie elementów projektowania mechatronicznego do nadzorowania drgań, którego celem jest minimalizacja amplitudy drgań końcówek manipulacyjnych, a w konsekwencji - poprawa dokładności i powtarzalności...

Multiobjective Water Distribution Systems Control of Pumping Cost, Water Quality, and Storage-Reliability Constraints
PublicationThis work describes a multiobjective model for trading-off pumping cost and water quality for water distribution systems operation. Constraints are imposed on flows and pressures, on periodical tanks operation, and on tanks storage. The methodology links the multiobjective SPEA2 algorithm with EPANET, and is applied on two example applications of increasing complexity, under extended period simulation conditions and variable energy...

Bending Moment Control and Weight Optimization in Space Structures by Adding Extra Members in the Optimal Locations
PublicationThis paper investigates the reduction of bending moment in critical members by adding some extra members in the optimum location. Instead of enlarging the size of members to resist the moment, eight additional members are added in the optimum location to reduce the bending moment in the critical members. The total weight of the proposed structure with extra members is less than that of the original structure that resists the induced...

Remote command and control capabilities for data acquisition systems provided by delay-tolerant network mechanisms
PublicationThe paper presents an assessment of a remote device reconfiguration service employing a Delay Tolerant Network (DTN) mechanisms. This service has been implemented as a part of a communication appliance dedicated to marine data transfer in off-shore and open sea areas. The service has been successfully deployed and validation test have been completed. The practical use-case has been defined as remote access to the equipment operating...

Interpretation and modeling of emotions in the management of autonomous robots using a control paradigm based on a scheduling variable
PublicationThe paper presents a technical introduction to psychological theories of emotions. It highlights a usable ideaimplemented in a number of recently developed computational systems of emotions, and the hypothesis thatemotion can play the role of a scheduling variable in controlling autonomous robots. In the main part ofthis study, we outline our own computational system of emotion – xEmotion – designed as a key structuralelement in...

Modification of the structural model of manipulator's carrying system for a use of modal control at energy performance index.
PublicationW pracy rozważa się drgania niestacjonarnego układu nośnego manipulatora IRb-6 modelowanego dyskretnie metodą sztywnych elementów skończonych. Z uwagi na gwałtowne ruchy (start, zatrzymanie) poszczególnych członów manipulatora, jest to problem o dużym znaczeniu praktycznym. Jednym ze sposobów nadzorowania tych drgań jest wykorzystanie sterowania modalnego przy energetycznym wskaźniku jakości. Uwzględnia on zmianę w czasie względem...

The possible unreliability of self-efficacy beliefs and perceived control - when nascent entrepreneurs may be overconfident
Publicationpoczucie samoskuteczności oraz poziom postrzeganej kontroli są istotnymi czynnikami decydującymi o wyborze działań oraz o wytrwałości w ich kontynuowaniu. zbyt wysokie poczucie samoskuteczności, które znacznie odbiega od faktycznej skuteczności oraz iluzja kontroli mogą powodować nadmierne zaangażowanie w działania, które mają znikome szanse powodzenia. artykuł przedstawia teoretyczną analizę znaczenia różnych źródeł poczucia samoskuteczności...

Successive cytotoxicity control by evolutionary surface decorated electronic push-pull green ZnCr-LDH nanostructures: Drug delivery enlargement for targeted breast cancer chemotherapy
PublicationThe reason for the increasing bioavailability and biocompatibility of the porous nanomaterials in the presence of different (bio)molecules is still unknown. The role of difference functional groups and their interactions with the potential bioavailability and biocompatibility is of great importance. To investigate the potential contribution of the electronic effects (especially on the surface of the porous nanomaterials) on their...
