Head (Fig. 1); antennal torulus placed slightly above lower margin of eye; malar space dark, as long as or shorter than eye width; ocelli arranged in obtuse triangle; mandible (Fig. 2) 4-dentate, third tooth shorter, and a concavity between third and fourth teeth; maxillary palp (Fig. 3) unsegmented, swollen basally, with one seta at apex. Antennal formula 1, 1, (2), 2, 3; antenna (Figs 5–8) with 2 anelli (Figs 7, 8: A1 and A2); funicle 2 segmented, segments asymmetrical, with PLS, F2 broader than long; clava 3-segmented with very long setae and PLS. Mesosoma with pronotum medially divided into two plates; mid lobe of mesoscutum and scutellum each with 2 pairs (2+2) setae; side lobe of mesoscutum with 1 seta along anterolateral corner and axilla; propodeal margin almost straight posteriorly and about as long as metanotum medially; posterior two-thirds of mesoscutum, and scutellum with longitudinally cellulate sculpture, anterior one-third of mesoscutum with polygonal cells. Fore wing hyaline with venation extending to slightly less than half wing length; costal cell very narrow; marginal vein longer than premarginal or stigmal veins; premarginal vein broader than marginal vein; RS1 absent [except two or three setae below stigmal vein]; disc moderately densely setose with setae arranged in rows. Legs with tarsal formula 3-3-3. Metasoma longer than mesosoma; ovipositor short, extending from TV of gaster and hardly exserted. Male. Unknown. Etymology. The genus is named after the son of the second author (SBA), Ayaan + ‘-ella’ Latin suffix added to generic name.Published as part of Khan, Mohd Talib & Anis, Shoeba Binte, 2017, A new genus of Trichogrammatidae (Hymenoptera: Chalcidoidea) from India, pp. 165-168 in Zootaxa 4344 (1) on pages 165-166, DOI: 10.11646/zootaxa.4344.1.9, http://zenodo.org/record/104236
A One-Way Car-Sharing Based Approach for Combined Shared Mobility of Freight and Passengers
No full textClimate change stresses the need for research and development of innovative sustainable mobility solutions that provide reliable and convenient door-to-door services for both passengers and freight. The increase in urban population and the popularity of e-commerce further highlights the need for action. In this regard, crowd-shipping is often perceived as an efficient, cost-effective, and sustainable alternative (or complement) to the management of urban freight mobility through efficient utilization of current transportation capacities. In this framework, inspired by the concept of MaaS (Mobility as a Service) in integrating various forms of transport and transport-related services into a single on-demand mobility service, this paper proposes a car-sharing-based service for the combined mobility of passengers and freight. In doing so, one-way car-sharing and crowd-shipping concepts are integrated in order to serve part of the existing freight demand in a sustainable and cost-efficient way for users, societies, and the environment. An optimization model is proposed to optimally plan the activation of one-way car-sharing and crowd-shipping services and to determine the optimal number of vehicles to assign to them. Such decisions are aimed at minimizing the total imbalance by serving passenger and freight demand during different time periods. In doing so, the willingness of users to carry freight in their vehicles is also taken into consideration. The capability of the proposed approach is evaluated through representative numerical examples aimed at showing the impact of the model parameters on the solution.Transport and Plannin
Online Diagnosis based on Chronicle Recognition of a Coil Winding Machine
No full textThis paper falls under the problems of the diagnosis of Discrete Event System (DES) such as coil winding machine. Among the various techniques used for the on-line diagnosis, we are interested in the chronicle recognition and fault tree. The Chronicle can be defined as temporal patterns that represent system possible evolutions of an observed system. Starting from the model of the system to be diagnosed, the proposed method based on the P-time Petri net allows to generate the chronicles necessary to the diagnosis. Finally, to demonstrate the effectiveness and accuracy of the monitoring approach, an application to a coil winding unit is outlined
Human Machine Interface for monitoring a winding machine
No full textThe monitoring function that we are developing is part of an overall monitoring process. It aims, on the basis of the information available on its operating modes, to detect, locate and diagnose failures that may affect its performance and operational safety. The purpose of this paper is to carry out a method for monitoring an automated system based on a Human Machine Interface (HMI). The purpose of monitoring task is the detection and the rapid localization of faults in order to minimize the average system downtime. Finally, we illustrate the implementation of the proposed supervision approach on a winding machine in order to monitor the bobbins quality
Robust Control under Uncertainty for Seaport Handling Equipments
No full textAbstractUncertainty in transport includes mainly unavailability of transportation resource, durations of maintenance activities and the infrastructure constraints. The uncertainty influences the transportation resource availability, and consequently the planned transport schedule. Developments presented in this paper are devoted to the robustness control of transportation system. A robust control strategy towards uncertainty is presented. The presented control strategy tries to reduce unavailability of machines in transportation system and to minimize the total transfer time. To illustrate the effectiveness and accuracy of proposed robustness approach, an application to a seaport handling equipments is outlined

No full textEmbracing the future of the policy sciences: big data in pedagogy and practice
No full textAlthough the emergence of Big Data provides an opportunity to synthesize and mobilize ever greater amounts of policy-relevant knowledge, it has not received adequate attention in studies of policy pedagogy and practice. In this chapter, we highlight the relevance of Big Data to policy analysis, policy implementation, and policy studies through a discussion of basic machine learning techniques and an illustration of their application in the case of better understanding policy response to COVID-19. Subsequently – based on a bibliometric review of nearly 2,500 publications on big data in public policy and content analysis of course titles and descriptions in 122 programs worldwide – we make an evidence-informed appeal to increase the uptake of big data in policy research as well as teaching. We conclude that appropriate engagement with the big data phenomenon can help the policy sciences remain relevant and move a step closer to integrating policy research, pedagogy, and practice.Green Open Access added to TU Delft Institutional Repository ‘You share, we take care!’ – Taverne project https://www.openaccess.nl/en/you-share-we-take-care Otherwise as indicated in the copyright section: the publisher is the copyright holder of this work and the author uses the Dutch legislation to make this work public.Organisation & Governanc
