Analog Multiple Description Joint Source-Channel Coding Based on Lattice Scaling

2015

Joint source-channel coding schemes based on analog mappings for point-to-point channels have recently gained attention for their simplicity and low delay. In this paper, these schemes are extended either to scenarios with or without side information at the decoders to transmit multiple descriptions of a Gaussian source over independent parallel channels. They are based on a lattice scaling approach together with bandwidth reduction analog mappings adapted for this multiple description scenario. The rationale behind lattice scaling is to improve performance through bandwidth expansion. Another important contribution of this paper is the proof of the separation theorem for the communication …

Thermoeconomic diagnosis of air conditioning systems: experimental assessment of performance for improved reliability

2018

Thermoeconomic diagnosis is an exergy-based fault detection and diagnosis technique which has been recently extended to air conditioning systems. So far, developments of this technique have relied only on simulation data without being evaluated using real data. For the first time, this work aims at assessing the performance of thermoeconomic diagnosis using experimental data obtained from a five-ton packaged rooftop air conditioning unit (RTU) installed at Herrick Laboratories, Purdue University. The RTU was tested in psychrometric chambers under a wide range of operating conditions and fault levels. The following faults were investigated: (i) evaporator fouling, (ii) condenser fouling and …

QUEXME: A Query Expansion Method Applied to Water Information System

2009

The aim of the paper is to present and apply a QUery EXpansion MEthod called QUEXME while querying the Euro-Mediterranean Information System (EMWIS) on know-how in the Water sector. EMWIS provides a strategic tool for exchanging information and knowledge in the water sector between and within the Euro Mediterranean partnership countries (www.emwis.net). Information retrieval on the web or through some cooperation of information sources or some general knowledge bases is a complex process and a great challenge with the emergence of the semantic web. The aim of the query expansion method is to help and guide users to build their requests giving them some usually related terms close to their q…

Il lavoro etero-organizzato prima e dopo il caso Foodora Italia.

2019

l contributo ripropone la discussione sull’esegesi della fattispecie disciplinata dall’art. 1 comma 2 del d. lgs. n. 81 del 2015 (nel testo anteriore alla riforma del 2019) trattata dall’autore nei Colloqui Giuridici sul Lavoro del 2015 (a cura) di Antonio Vallebona per il Massimario di Giurisprudenza del Lavoro. Lo studio rigettava la tesi che il lavoro organizzato dal committente fosse la terza fattispecie e anzi con riferimento delle condizioni di applicazio­ne dimostrava la necessità di una lettura includente. La conclusione era che la nuova disciplina aveva natura antifraudolenta e determinava un allargamento (relativo) dell’area della subordi­nazione conseguente alla riduzione del cam…

This article republishes (after the Italian Supreme Court judgement n.166/2020 on the Foodora Italia case) the contribution to the exegesis of the case brought by art. 1 para­graph 2 of the d. lgs. n. 81 of 2015 (in the text before the 2019 reform) delivered by the author in the 2015's "Colloqui Giuridici sul Lavoro" (edited) by Antonio Vallebona for the "Massimario di Giurisprudenza del Lavoro". The study rejected the thesis that the job organ­ised by the client was an intermediate regulation between the employee and the self-employed ones. Indeed regarding the conditions for its application it showed the need for extensive reading. The conclusion was that the new discipline was (and is) an anti-fraudulent one. It led to a (relative) expansion of the area ofsubordination as a consequence of a reduction in the scope of coordinated self-employed work. A little more than four years after that article the Italian Supreme Court (with the judgement n.166/2020) on the Foodora Italia case addresses for the first time the issue of the hetero-organised work (by art. 1 paragraph 2 of the d. lgs. n. 81 of 2015). The Supreme Court fully adheres to the paper's thesis. So in terms of the "re­medial" function of the standardthe nature of the organisation's specific conditionand eventually reducing the legal frame for coordinated work. The fact that the procedural matter dealt with the riders was (then and now is) utterly irrelevant for the correct interpretation of such a new provision. Giving to riders of the employee status is not an effect of the peculiarit­ies of the work through digital platforms. It is a consequence of the remedial nature of such a case-law.

The expansion of a European feudal monarchy during the 13th Century: the Catalan-Aragonese Crown and the consequences of the conquest of the kingdoms…

2009

-Enric.Guinot@uv.es In the middle of the 13th century the Crown of Aragon conquered by military means the Muslim Mediterranean Coast of the Iberian Peninsula, incorporating it into the European feudal world; this resulted in the destruction of the Andalusí state and part of its society as well as in a redistribution of towns, villages, houses and lands among Christians. The historiography of some years ago emphasized the role of trade and urban burgesses in these new societies, but present opinion is more related to a long expansion of feudal society as well as the creation in Majorca and Valencia of a colonial society. Logically, the consequences of this process had also an effect in Catal…

Unitary transformations depending on a small parameter

2011

We formulate a unitary perturbation theory for quantum mechanics inspired by the LieDeprit formulation of canonical transformations. The original Hamiltonian is converted into a solvable one by a transformation obtained through a Magnus expansion. This ensures unitarity at every order in a small parameter. A comparison with the standard perturbation theory is provided. We work out the scheme up to order ten with some simple examples.

Role of coefficient of thermal expansion on bond strength of ceramic veneered yttrium-stabilized zirconia

2017

Background Incompatible coefficient of thermal expansion (CTE) is supposed to be a reason for chipping of ceramic veneered zirconia. This study evaluates the effect of veneering ceramic at varied CTE on bond strength to zirconia. Material and Methods Zirconia disks (Z, O 10 mm, 1.0 mm thickness) were prepared from Y-TZP (Cercon®) and sintered at 1350°C for 6 hours. All zirconia disks were veneered with ceramics ((O 7.0 mm, 1.5 mm thickness) with varied CTE including VITADur® alpha (VDα), VITAVM®7 (VM7), VITAVM®9 (VM9), Cercon® ceramkiss (CCK), IPSe.max® ceram (IeC), and IPS dSIGN® (IdS) (n=15). The specimens were thermo-cycled (5-55 °C, 500 cycles) prior to determine the shear bond strength…

Myotonic dystrophy associated expanded CUG repeat muscleblind positive ribonuclear foci are not toxic to Drosophila

2005

Myotonic dystrophy type 1 is an autosomal dominant disorder associated with the expansion of a CTG repeat in the 3 0 untranslated region (UTR) of the DMPK gene. Recent data suggest that pathogenesis is predominantly mediated by a gain of function of the mutant transcript. In patients, these expanded CUG repeat-containing transcripts are sequestered into ribonuclear foci that also contain the muscleblind-like proteins. To provide further insights into muscleblind function and the pathogenesis of myotonic dystrophy, we generated Drosophila incorporating CTG repeats in the 3 0 -UTR of a reporter gene. As in patients, expanded CUG repeats form discrete ribonuclear foci in Drosophila muscle cell…
