Działalność Zagranicznego Komitetu Odbudowy Zamku Królewskiego w Warszawie (1967–1972)

2018

Zdecydowana większość emigracyjnych elit politycznych zajęła negatywne stanowisko w sprawie zbiórki pieniędzy na restytucję Zamku Królewskiego w Warszawie. W 1. połowie lat 70. XX w. na całym świecie działało jednak kilkadziesiąt komitetów i organizacji polonijnych wspierających ową inicjatywę, najwięcej w Stanach Zjednoczonych, Australii, we Francji i w Kanadzie. Chronologicznie pierwszy tego typu komitet zawiązał się jeszcze w czerwcu 1967 r. w Londynie, na kilka lat przed decyzją władz PRL w sprawie podniesienia z ruin byłej siedziby królewskiej. Przewodniczącym Zagranicznego Komitetu Odbudowy Zamku Królewskiego w Warszawie został Ignacy Czaykowski. W skład komitetu weszły osoby, które w…

Boosting the performance of a Reverse Electrodialysis – Multi-Effect Distillation Heat Engine by novel solutions and operating conditions

2019

Abstract This work presents a performance analysis of a waste-heat-to-power Reverse Electrodialysis Heat Engine (RED-HE) with a Multi-Effect Distillation (MED) unit as the regeneration stage. The performance of the system is comparatively evaluated using two different salts, sodium chloride and potassium acetate, and investigating the impact of different working solutions concentration and temperature in the RED unit. For both salt solutions, the impact of membrane properties on the system efficiency is analysed by considering reference ionic exchange membranes and high-performing membranes. Detailed mathematical models for the RED and MED units have been used to predict the thermal efficie…

¿Por qué conservamos la biodiversidad? Un breve recorrido sociológico, psicológico y moral

2017

espanolEn este trabajo se muestran, de manera muy sucinta, algunos conceptos fundamentales sobre los valores que subyacen en la toma de las decisiones sobre la conservacion de la biodiversidad, asi como las bases psicologicas de la deliberacion en este contexto. Para ello, se describe, en primer lugar, un modelo sociologico clasico que ayuda a predecir la asignacion de recursos para la conservacion, basado en la construccion social y el poder “politico” oculto de las diferentes especies. En segundo lugar, se vincula dicho modelo con la taxonomia de valores subyacentes (no necesariamente excluyentes). Finalmente, se discute la base psicologica de la deliberacion valorativa a partir de la teo…

Membrane Bioreactors for wastewater reuse: Respirometric assessment of biomass activity during a two year survey

2018

Abstract Stricter effluent limits, water shortage conditions, land availability requires today even more the needs of advanced wastewater treatments. Attractive solutions come from membrane bioreactors (MBR), Integrated Fixed Film Activated Sludge (IFAS) or combinations (i.e., IFAS-MBRs). One crucial aspect for the applicability of this overall new technology, compared to the conventional activated sludge systems, is the lack of knowledge for design and manage (e.g., kinetic constants, optimal operative conditions etc.). In view of the above frame, the aim of the present study was to assess the kinetic and stoichiometric parameters of bacterial species in MBRs by means of respirometric tech…

SEMANTIC MANAGEMENT OF INTELLIGENT MULTI-AGENTS SYSTEMS IN A 3D ENVIRONMENT

2011

8 pages; International audience; This paper presents a new approach combining the 3D elements composing the environment of mobile agents with semantic descriptors from Building Information Models. Our proposal is based on the IFC standard, which is used in the field of Civil Engineering to build digital models of buildings during the design phase. The semantic of IFC objects composing the 3D environment is used to select and set up 3D objects and elements of simulation scenarios. The result of this process dynamically generates the input files for the JaSIM environment that performs the simulation. These files deserve the representation of the virtual environment in which the simulation is …

Ontological Analysis of the Project Risk Management Concept ‘Risk’

2018

Abstract The aim of the current research series is to examine the definitions of the concept ‘risk’ and analyze the concepts used in the definitions of ‘risk’ in the sources of these definitions in order to perform the ontological analysis of the concept of ‘risk’. Ontological and epistemological analysis of the concepts in the definition of the concept ‘risk’ was used to answer the question what ‘risk’ means in project management. This investigation represents a part of the research series where the ontological, epistemological and methodological analysis of project risk is performed with the aim to improve risk registers and risk management as a whole. In the previous studies the author a…

From common operational picture to common situational understanding: An analysis based on practitioner perspectives

2021

Abstract The concepts of Situational Awareness (SA) and Common Operational Picture (COP) are closely related and well-acknowledged to be crucial factors for effective emergency management. In multi-agency operations, such as extreme weather events, the involved first responders manage the event with different mandates, objectives, and tools which can make it challenging to build a COP. Effective collaboration requires a common situational understanding, based on knowledge about each other’s responsibilities and tasks, mutual respect and trust, as well as common communication tools for emergency communication and information sharing. This paper argues that the COP serves as a basis for decid…

Taking the Advantage of Smartphone Apps for Understanding Information Needs of Emergency Response Teams’ for Situational Awareness: Evidence from an …

2016

In search and rescue (SAR) operation, a lot of information is being shared among different emergency response groups. However, one of the key challenges experienced by these rescue groups during SAR operation is obtaining the complete awareness of the situation from the shared information. Moreover, one of the key actions of rescue leaders is to get the needed information in order to coordinate effectively with other teams and perform well. So, in this study we conduct an indoor fire drill with the help of Smartphone application with two settings (without SmartRescue smartphone application and with SmartRescue smartphone application) to find out what type of information is mostly communicat…

Creating futures images for sustainable cruise ships : insights on collaborative foresight for sustainability enhancement

2021

The aim of the study was to explore futures images of collaborative sustainability enhancement within a cruise ship building network. Addressing collaborative sustainability at the organizational level rather than at the macro (regional or planetary) level, the paper explores socially constructed and shared futures images, which are less widely studied than individual-level images of the future. We advance an analytical model for constructing and evaluating collectively held futures images based on the structure and content of those images. From our data, we identified four futures images: Money rules; The customer is always right; Local economy focus; and The most sustainable ships in the …
