Automatic Generation of Figural Analogies With the IMak Package

2018

Automatic Item Generation (AIG) techniques are offering innovative ways to produce test items as they overcome many disadvantages involving standard item writing, such as time-consuming work and resource-intensive demands. Although this field is relatively new, it is progressing at a high speed, and several contributions have been accomplished. Nevertheless, a scarce amount of AIG software evidencing favorable psychometric properties of the generated items has been made accessible to the broad scientific community. This research had two goals: first, to present an empirical study of items produced with the aid of the Item Maker (IMak) package available online and, second, to present IMak it…

The perception of odor objects in everyday life: a review on the processing of odor mixtures

2014

International audience; Smelling monomolecular odors hardly ever occurs in everyday life, and the daily functioning of the sense of smell relies primarily on the processing of complex mixtures of volatiles that are present in the environment (e.g., emanating from food or conspecifics). Such processing allows for the instantaneous recognition and categorization of smells and also for the discrimination of odors among others to extract relevant information and to adapt efficiently in different contexts. The neurophysiological mechanisms underpinning this highly efficient analysis of complex mixtures of odorants is beginning to be unraveled and support the idea that olfaction, as vision and au…

Struktur-Wirkungs-Beziehungen bei Histaminanaloga, 18. Mitt. Absolute Konfiguration und histaminartige Wirkung der Enantiomere von 5-Amino-4,5,6,7-te…

1979

Es werden die Racemattrennung von 5-Amino-4,5,6,7-tetrahydro-benzimidazol (3), die Bestimmung der absoluten Konfiguration sowie die histaminartige Wirksamkeit der Enantiomere am Ileum (H1) und Atrium (H2) des Meerschweinchens beschrieben. Structure-Activity Relationship of Histamine Analogues, XVIII: Absolute Configuration and Histamine-like Activity of the Enantiomers of 5-Amino-4,5,6,7-tetrahydrobenzimidazole The resolution of 5-amino-4,5,6,7-tetrahydrobenzimidazole (3), the determination of the absolute configuration and the histamine-like activity of the enantiomers on the guinea-pig ileum (H1) and atrium (H2) are reported.

Stereoselective Synthesis of the Antiprotozoal Lactone Passifloricin A and Seven Isomers Thereof

2004

The conjugated delta-lactone passifloricin A, a natural product with antiprotozoal activity, and seven isomers thereof have been synthesized in enantiopure form. It has been shown in this way that the proposed structure for the natural compound was erroneous. The correct structure is now evidenced. Key steps of the syntheses were asymmetric Brown-type aldehyde allylations and ring-closing metatheses.

On automatic algorithm configuration of vehicle routing problem solvers

2019

Many of the algorithms for solving vehicle routing problems expose parameters that strongly influence the quality of obtained solutions and the performance of the algorithm. Finding good values for these parameters is a tedious task that requires experimentation and experience. Therefore, methods that automate the process of algorithm configuration have received growing attention. In this paper, we present a comprehensive study to critically evaluate and compare the capabilities and suitability of seven state-of-the-art methods in configuring vehicle routing metaheuristics. The configuration target is the solution quality of eight metaheuristics solving two vehicle routing problem variants.…

A Dynamic Electrical Scheme for the optimal reconfiguration of PV modules under non-homogeneous solar irradiation

2012

This paper presents a strategy for the maximization of the output power of photovoltaic (PV) systems under non homogeneous solar irradiation by means of automatic reconfiguration of the PV arrays layout. The innovation of the proposed approach is the employment of a simple Dynamic Electrical Scheme (DES), allowing a large number of possible modules interconnection, to be installed between the PV generator and the inverter. The models of the PV generator and of the DES have been realized and simulated with Simulink (Dynamic System Simulation for MATLAB). The attained experimental results appear to be quite interesting in terms of the attainable benefit in power and thus energy terms. The lim…

Mobile Technology Adoption and the Effects of Cultural Factors

2019

Mobile technologies are an important part of human life in both the personal and professional realms. Many services (banking, news, health, education, etc.) that traditionally offered either face-to-face, telephone, or other conventional platforms and technologies are now establishing services on mobile platforms as well. Mobile gadgets are now also being used by company employees as sales automation tools. The importance of culture in technology adoption and usage has been well-established. The adoption of any technology includes a set of factors that determine if the technology is either accepted or rejected, and the individual strengths of these determining factors may vary greatly, depe…

Engraved in the Body : Ways of Reading Finnish People's Memories of Mental Hospitals

2021

Finnish psychiatric practice has been heavily based on institutionalization. Mental hospitalsMental hospital have thus been part of Finns' lives in many ways. Our multidisciplinary researchMultidisciplinary research group has investigated how experiences in these institutions are remembered today by analysing writings by patients, relatives, personnel and their children, collected in 2014--2015 with the Finnish Literature Society. The memoriesMemory cover phases of psychiatric care from the 1930s to the mid-2010s. This article presents multiple ways in which experiences that are often difficult verbalize can be interpreted, e.g. by drawing on perspectives from creative, artistic and cultura…
