From βαλανεῖα to thermae: unveiling the transition from Greek to Roman architectural models of baths by technological and provenance archaeometric st…

2019

So far unexplored, the introduction and the spread of the Roman thermal buildings in the prima provincia (Sicily) are widely debated in the current archeological studies. Mainly due to the lack of systematic excavations and intensively technological studies, the assessment of thermae in the Hellenistic-Roman Sicily has been thus far interpreted as a new social and architectural experience. However, a more careful archeological investigation would suggest a gradual transformation of the architectural landscape from the purely Greek bath tradition to the canonical thermae types. The aim of this paper is therefore to study the classical hot bath culture and, in particular, the transition from …

Caesarvs : el dios venerado en el templo del Collado de las Piedras Labradas (Jarilla, Cáceres).

2018

En el presente artículo estudiamos algunas inscripciones votivas halladas junto a las ruinas del templo romano del Collado de las Piedras Labradas (Jarilla, Cáceres). Hasta el momento, no se conocía el nombre de la deidad venerada en este recinto sagrado pero, a partir del estudio de dos de las inscripciones que de allí proceden, hemos podido concluir que el dios adorado en este templo era Caesarus, una deidad indígena lusitana. A partir de esta identificación hemos investigado el significado del teónimo y de su único posible paralelo: Caesariciaecus, testimoniado en el pueblo de Martiago (Salamanca). Teniendo en cuenta estos datos y el contexto montañoso en el que se situaba el templo, hem…

Considerazioni sulle strutture edilizie dell'area del Tempio-Criptoportico

2013

Il contributo si prefigge lo scopo di analizzare le emergenze architettoniche dell'area del Tempio-Criptoportico, centro cultuale della città romana di Urbs Salvia. Il grande complesso sntuariale venen eretto in età tiberiano-claudia al di sopra di un quartiere abitativo di notevole pregio che si affacciava sul lato orientale del Foro della città. Un poderoso Criptoportico fungeva da sostegno ad un Tempio esastilo corinzio, del quale oggi restano solo scarni resti del podio, circondato da un portico su tre lati. Lo studio propone una ipotesi ricostruttiva del complesso e delle sue fasi di vita.

Il Tempio-Duomo di Pozzuoli. Lettura e Progetto

2007

Il progetto presentato al concorso per il restauro del Tempio-Duomo di Pozzuoli, diviene una occasione di ricerca che si propaga oltre la conclusione del confronto internazionale. I tre coautori, infatti, includono nella pubblicazione, oltre alle tavole di rilievo, di progetto e agli altri elaborati a corredo della proposta, ulteriori approfondimenti. Attraverso questi, da angolazioni diverse, si dimostrano la complessità degli argomenti fornita dall’occasione concorsuale e le ragioni per cui era corretto proseguire lo studio. In particolare, nella sua riflessione a posteriori, Andrea Sciascia sostiene quanto centrale sia stato nel progettare un testo architettonico molto stratificato e fra…

Aparatūra “Lotoss” poliuretāna plastmasas detaļu atliešanai kosmosā

2020

1980. gadā kosmosa stacijā “Salūts” pirmoreiz kosmonautikas vēsturē tika realizēts putupoliuretāna ieguves eksperiments mikrogravitācijas apstākļos, kura rezultāta tika iegūtas jaunas atziņas par ķīmiski tehnoloģisko procesu norisi kosmosā. Kosmosā tapa Maskavas olimpisko spēļu simbola lācīša figūra. Iekārtu "Lotoss", kas pašreiz atrodas Latvijas Ķīmijas vēstures muzeja krājumā, LPSR Zinātņu Akadēmijas Koksnes ķīmijas institūtā izstrādājis latviešu ķīmiķis, ķīmijas doktors, izgudrotājs un gleznotājs Arnolds Alksnis, un tā domāta polimerizācijas reakciju pētīšanai bezsvara stāvoklī.

Modelling and prediction of retention in high-performance liquid chromatography by using neural networks

1995

Multi-layer feed-forward neural networks trained with an error back-propagation algorithm have been used to model retention behaviour of liquid chromatography as a function of the composition of the mobile phases. Conventional hydro-organic and micellar mobile phases were considered. Accurate retention modelling and prediction have been achieved using mobile phases defined by two, three and four parameters. With micellar mobile phases, the parameters involved included the concentrations of surfactant and organic modifier, pH and temperature. It is shown that neural networks provide a competitive tool to model varied inherent nonlinear relationships of retention behaviour with respect to the…

An Application of Hybrid Models in Credit Scoring

2000

The predictive capability of parametric and non-parametric models in solving problems related to financial classification has been widely proved in empirical research carried out in the financial field, particulary in problems like bond rating, bankruptcy prediction and credit scoring. However, recently, it has been shown that a combination of different models generally reduces the prediction error, so that the best alternative to consider may not be a specific model but a combination of them. In this paper, we study hybrid systems based on the aggregation of individual (parametric and nonparametric) models. Our hybrids are built by using both parametric and non parametric models as the sys…

CostNet: An End-to-End Framework for Goal-Directed Reinforcement Learning

2020

Reinforcement Learning (RL) is a general framework concerned with an agent that seeks to maximize rewards in an environment. The learning typically happens through trial and error using explorative methods, such as \(\epsilon \)-greedy. There are two approaches, model-based and model-free reinforcement learning, that show concrete results in several disciplines. Model-based RL learns a model of the environment for learning the policy while model-free approaches are fully explorative and exploitative without considering the underlying environment dynamics. Model-free RL works conceptually well in simulated environments, and empirical evidence suggests that trial and error lead to a near-opti…
