Modeling the escalation/de-escalation of response operation levels in disaster response networks using hierarchical Colored Petri Nets (CPN) approach
2018
In emergency situations, the first responders need to act promptly to situations, while the disaster management authorities' response might not be at the same speed. Delays by disaster management authorities had a direct impact on response operations led response teams to the shift away from command and control structures to net-centric ones. This paper is part of a study to examine patterns of emerging organizational relations and coordination structures in disaster response operations. Understanding coordination patterns in disaster chaos can help to integrate those patterns in the planning and execution in the modern disaster management operations. We use dynamic modeling methods to anal…
Experimental Command and Control Center for Crisis and Disaster Management: A Living-Lab Approach
2021
The living-lab is a planned research infrastructure that includes user involvement and the co-design process. This article presents an overview of the innovative experimental control room for crisis management that adopts this living-lab approach in all research co-creation activities. The aims of this paper are threefold: (1) To study possible control room research methods, focus areas, and technologies that can be tailored to the living-lab approach; (2) To illustrate and share experience on the possibilities to tailor an experimental command and control center as a living-lab. (3) To explore the features to fulfill to maximize the benefit of the living-lab for all intended audiences. By …
Student outcomes in Philippine elementary schools: An evaluation of four experiments
1999
International audience; Policymakers in most developing countries are concerned about high dropout rates and poor student learning in primary education. The government of the Philippines initiated the Dropout Intervention Program in 1990-92 as part of its effort to address these issues. Under this program, four experimental interventions were randomly assigned to 20 schools in selected low-income areas. Pre- and post-intervention data were collected from these schools, as well as from 10 control schools, in order to evaluate the program's impact on dropout behavior and student learning. The economic justification for replication appears to be strongest for the interventions that provided te…
Positions constructed for a female therapist in male batterers' treatment group
2012
How the gender of the therapist affects the treatment of intimately violent men has been little researched. In this study we examined the positions that batterers construct for a female therapist in batterers' group treatment. The data consisted of five videotaped therapy groups for male batterers. Three positions of a woman were constructed: woman in general; woman as spouse and woman personally as herself. These positions were often based on a constructed difference between men and women. The female therapist repositioned herself to diminish the difference constructed between the genders and to make fear of the spouse visible. peerReviewed
On a class of compactly epi-Lipschitzian sets
2003
The paper is devoted to the study of the so-called compactly epi-Lipschitzian sets. These sets are needed for many aspects of generalized differentiation, particulary for necessary optimality conditions, stability of mathematical programming problems and calculus rules for subdifferentials and normal cones. We present general conditions under which sets defined by general constraints are compactly epi-Lipschitzian. This allows us to show how the compact epi-Lipschitzness properties behave under set intersections.
Decompositions of Weakly Compact Valued Integrable Multifunctions
2020
We give a short overview on the decomposition property for integrable multifunctions, i.e., when an &ldquo
Single-input perturbative control of a quantum symmetric rotor
2022
We consider the Schr\"odinger partial differential equation of a rotating symmetric rigid molecule (symmetric rotor) driven by a z-linearly polarized electric field, as prototype of degenerate infinite-dimensional bilinear control system. By introducing an abstract perturbative criterium, we classify its simultaneous approximate controllability; based on this insight, we numerically perform an orientational selective transfer of rotational population.
Chattering phenomenon in quantum optimal control
2022
We present a quantum optimal control problem which exhibits a chattering phenomenon. This is the first instance of such a process in quantum control. Using the Pontryagin Maximum Principle and a general procedure due to V. F. Borisov and M. I. Zelikin, we characterize the local optimal synthesis, which is then globalized by a suitable numerical algorithm. We illustrate the importance of detecting chattering phenomena because of their impact on the efficiency of numerical optimization procedures.
NIGHT-Care: A Passive RFID System for Remote Monitoring and Control of Overnight Living Environment
2014
AbstractAn Ambient Intelligence platform, NIGHTCare, for remote monitoring and control of overnight living environment is here proposed. The platform, entirely based on RFID passive technology is able to recognize nocturnal behaviors and activities, generates automatic alarms in case of anomalous or pathological events and support diagnostics. The results of a complete test in real scenario are presented, together with a numerical assessment of electromagnetic safety issues.
Spectral Measurement of Photon Emission from Individual Gold Nanoparticles Using Scanning Tunneling Microscopy
2016
The light emission spectra of individual Au nanoparticles induced by a scanning tunneling microscope (STM) have been investigated. Two-dimensional ensembles of tunnel-coupled Au particles were prepared by thermal evaporation onto a native oxide silicon wafer in ultrahigh vacuum (10 – 9 mbar). Our STM measurements show a single peak at photon energy 1.6 eV in the tunneling mode and two peaks at 2.2 eV (connected with the Mie plasmon) and 1.45 eV (a new peak which was not discussed in literature before) in the field emission mode.
