An empirically grounded agent based simulator for the air traffic management in the SESAR scenario

2017

In this paper we present a simulator allowing to perform policy experiments relative to the air traffic management. Different SESAR solutions can be implemented in the model to see the reaction of the different stakeholders as well as other relevant metrics (delay, safety, etc). The model describes both the strategic phase associated to the planning of the flight trajectories and the tactical modifications occurring in the en-route phase. An implementation of the model is available as an open-source software and is freely accessible by any user. More specifically, different procedures related to business trajectories and free-routing are tested and we illustrate the capabilities of the mode…

Scaling laws of strategic behavior and size heterogeneity in agent dynamics

2008

The dynamics of many socioeconomic systems is determined by the decision making process of agents. The decision process depends on agent's characteristics, such as preferences, risk aversion, behavioral biases, etc.. In addition, in some systems the size of agents can be highly heterogeneous leading to very different impacts of agents on the system dynamics. The large size of some agents poses challenging problems to agents who want to control their impact, either by forcing the system in a given direction or by hiding their intentionality. Here we consider the financial market as a model system, and we study empirically how agents strategically adjust the properties of large orders in orde…

Arbitrary qudit gates by adiabatic passage

2013

We derive an adiabatic technique that implements the most general SU($d$) transformation in a quantum system of $d$ degenerate states, featuring a qudit. This technique is based on the factorization of the SU($d$) transformation into $d$ generalized quantum Householder reflections, each of which is implemented by a two-shot stimulated Raman adiabatic passage with appropriate static phases. The energy of the lasers needed to synthesize a single Householder reflection is shown to be remarkably constant as a function of $d$. This technique is directly applicable to a linear trapped ion system with $d+1$ ions. We implement the quantum Fourier transform numerically in a qudit with $d=4$ (defined…

Goodness-of-fit tests in many dimensions

2004

A method is presented to construct goodness-of-fit statistics in many dimensions for which the distribution of all possible test results in the limit of an infinite number of data becomes Gaussian if also the number of dimensions becomes infinite. Furthermore, an explicit example is presented, for which this distribution as good as only depends on the expectation value and the variance of the statistic for any dimension larger than one.

The Wage Curve, Once More with Feeling: Bayesian Model Averaging of Heckit Models

2018

The sensitivity of the wage curve to sample-selection and model uncertainty was evaluated with Bayesian methods. More than 8000 Heckit wage curves were estimated using data from the 2017 household survey of Bolivia. After averaging the estimates with the posterior probability of each model being true, the wage curve elasticity in Bolivia is close to -0.01. This result suggests that in this country the wage curve is inelastic and does not follow the international statistical regularity of wage curves.

Wooden biochar as a carrier for endophytic isolates

2017

Abstract Plant growth promoting microorganisms (PGPM) serve as a basis for bio-fertilizers. The aim of this study was to evaluate the wood-derived biochar as a potential carrier for PGPM, previously isolated from plants. The selected microbial consortium was compatible with aged biochar obtained from tree branches and processed at temperatures of 600–800 °C. The effect of the consortium or biochar alone and biochar carrier-based bio-formulation on plant growth was estimated in a 14-day greenhouse experiment with barley. The length of shoots and roots increased by 46% and 32% respectively in comparison with control. Synergy of consortium with biochar was observed regarding root length. Conso…

Ascorbic Acid Stability in Ground Asparagus Samples and in Oxalic Acid Extracts

1995

To establish the storage conditions for asparagus preparation before ascorbic acid determination, samples were ground, the mass was divided into three aliquots that were, respectively, stored at 4°C, – 18°C, or extracted with 1% oxalic acid. The extract was further split into aliquots and stored at 25°, 4°, –18° and -75°C. Ascorbic acid content was measured at different times of storage by a polarographic method. The rate of degradation increased with storage temperature; the degradation rate was higher in ground samples than in extracts; no significant changes in ascorbic acid content were observed in extracts stored for 7 days at -18° or for 90 days at -75°C.

Historia Domu Rekolekcyjnego Konferencji Episkopatu Polski "Księżówka" w Zakopanem w latach 1910-1945

2016

W artykule została przedstawiona droga do zrealizowania, podjętego w 1891 r., przez Stowarzyszenie Domu Zdrowia dla Kapłanów w Zakopanem założenia, budowy domu wspólnoty, z uwzględnieniem bazy zakładu leczniczego. Obiekt przyjmował różną formułę: od domu dla księży w celach zdrowotnych, turystycznych po współczesne funkcje rekolekcyjno-szkoleniowe; od przeznaczenia dla osób wyłącznie duchownych, po szeroką ofertę korzystania z domu przez osoby świeckie. Tekst wprowadza w atmosferę panującą w „Księżówce” w czasach zaboru austriackiego, w II Rzeczypospolitej oraz w okresie okupacji hitlerowskiej.
