Abstraction of Representation for Interoperation
No full textion of Representation for Interoperation David A. Maluf and Gio Wiederhold Department of Computer Science Stanford University Stanford, CA 94305 Abstract. When combining data from distinct sources, there is a need to share meta-data and other knowledge about various source domains. Due to semantic inconsistencies, problems arise when combining knowledge across domains and the knowledge is simply merged. Also, knowledge that is irrelevant to the task of interoperation will be included, making the result unnecessarily complex. An algebra over ontologies has been proposed to support disciplined manipulation of domain knowledge resources. However, if one tries to interoperate directly with the knowledge bases, semantic problems arise due to heterogeneity of representations. This heterogeneity problem can be eliminated by using an intermediate model that controls the knowledge translation from a source knowledge base. The intermediate model we have developed is based on the concept of abst..

An architectural gem
No full textThe School of Mathematics is one of Gio Ponti's major achievements and certainly one of the highest expressions of Italian Modernism. This chapter explains the main architectural and urban features of the building and it's context within the university campus of Rome. To the well know exceptional library, a unique example in the history of architecture, the author has dedicated a brief description, highlighting the role of the stained glass window originally designed by Ponti for this room and for the main facade of the building. The chapter closes with a thorough telling of the life of the building, from construction to nowadays, describing the many extensions, alterations and modifications. which have blurred the original "crystal-like" shape designed by Gio Ponti
Construction of a chamber to measure liquid lithium alloy vapor pressures and measurement of the lead-lithium eutectic vapor pressure

The chamber was made of three sections. The first section was a suitcase was made to transport air sensitive samples (such as lithium) between LAVA and storage in a glove box. The second section was a load lock that allows the transfer of samples into or out of the lower chamber. The third section could then be kept at high or ultra-high vacuum almost continuously. Keeping the lower section at this low pressure minimized the turnaround time between tests; although, bringing this section up to atmosphere is sometimes unavoidable. This section housed the stage for the sample holders and the heating coils. To measure the lithium alloys— Pb83Li17 is the alloy of interest in this thesis— in LAVA, the Knudsen effusion technique is used. This involves placing the alloy into a so-called Knudsen cell, which maintains a stable vapor pressure of the alloy, while allowing a small amount of evaporate to escape through an orifice. To do this the cell must: be compatible with the samples used (lithium, lead, and tin), be at a uniform temperature during testing, and have a properly designed effusion orifice. To address the compatibility and temperature uniformity, molybdenum was chosen as the cell material. The shape of the effusion orifice was chosen to be that of a cone rather than a cylinder with the small hole facing outward (a diameter of 3 mm for the small side and 12.66 mm for the larger side). In addition to a Knudsen cell, the Knudsen effusion technique requires the measurement of the change in sample mass from an evaporation run. In LAVA this was done using a dual Quartz Crystal Microbalance (QCM). The QCM was centered over the Knudsen cell, and given the cosine distribution of the evaporate, the viewing factor of the QCM crystal can be calculated and used to determine the total mass loss of the sample in the cell. However, to accurately determine the vapor pressure from the change in mass, the species of the evaporate must be known as well as how much of the evaporate it makes up. So, to modify the Knudsen effusion technique to work for multi species evaporate, and to determine the composition of the evaporate, witness plates were used to capture some evaporate material. These silicon wafers were positioned above the Knudsen cell to allow for the evaporate to deposit onto them. To make the lithium alloys produce a measurable amount of evaporate for this setup, they must be molten. The approach to this in LAVA was to use an induction heater. The induction heater allowed for volumetric heating and thus a simple heating design. Another benefit of induction heating (over something like resistive heating) is that it can heat a workpiece very quickly. Over the course of data collection, there were issues with having the QCM too close to the evaporate source, which caused jumps in the frequency measured. This was fixed by moving the QCM farther away, but that lowered the evaporate signal to background ratio, meaning that higher temperatures would be required to be able to make meaningful measurements. Data collection began with measurement of lithium vapor pressure to confirm that vapor pressures could be measured correctly in LAVA. This was done before and after the issue with the QCM was found. With the confirmation of the lithium runs prior to lead-lithium, it was necessary to adapt the Knudsen effusion technique to work with the expected two evaporate species of lead-lithium. The approach taken with this was to collect the evaporate onto witness plates, remove the plates and analyze them. One of the few techniques available that could even detect lithium was TOF SIMS. In addition to being able to detect lithium, a composition of the evaporate was also able to be made. This composition was used to weigh the data from the QCM to determine ”partial vapor pressures” of lead and lithium to calculate a total vapor pressure. Before the QCM issue became significant, the lead-lithium vapor pressures overestimated the literature vapor pressures by at least one order of magnitude. The lead-lithium vapor pressures measured appear to be uniform over the temperature range (500 K to 750 K). These values hover around 1 × 10^−5 Torr. Along with the vapor pressures, the cell mass loss rate was calculated from the QCM data. Over the same temperature range, the values ranged from 250 ng s^−1 to 1400 ng s^−1. The values did not have a clear relationship with temperature. Further converting the cell mass loss rate to particle flux from the cell did not appear to create any trends with temperature and ranged in value from 1 × 10^16 cm^−2 s^−1 to 1 × 10^17 cm^−2 s^−1. All of this data also was dependent on the composition of the evaporate, which was found to have significant amounts of lead across the temperature range (in atomic percentages: 11 % to 100 %). Like with the mass rate and particle flux, there was no apparent trend in composition. After the QCM issue was addressed, the overestimation of lead-lithium vapor pressure became at least an order of magnitude larger. The temperature range was increased to 550 K to 800 K due to the induction heater not being able to maintain temperature at the lower end of the previous temperature range. The values for vapor pressure ranged from 1 × 10^−4 Torr to 1 × 10^−2 Torr, with the highest point around 700 K. Unlike the previous iteration, the evaporate composition results showed that the evaporate was all lithium. Because no lead was detected in the Time of Flight Secondary Ion Mass Spectrometry (TOF SIMS) machine, X-Ray Fluorescence (XRF) was also done on the samples to confirm this and did not detect any lead. Because this disagrees with the previous data, there may be some issue with re-evaporation or the repeatability of the measurements at these temperatures. To address the issues with overshooting vapor pressure and disagreement of composition results of the previous two data sets, an increased cell temperature and therefore the vapor pressure was used. The new temperature range was 800 K to 1200 K. This ended up working, as the experimental lead-lithium vapor pressures were within one order of magnitude of the experimental data. The measured vapor pressures were in the range 1 × 10^−3 Torr to 1 × 10^−1 Torr. The particle flux data also made more sense than in either previous iteration. The overall particle flux did increase with increasing temperature. The particle fluxes ranged from 1 × 10^20 cm^−2 s^−1 to 1 × 10^21 cm^−2 s^−1. Composition results remained significantly lead heavy with samples having 70 % to 100 % (atomic) lead concentrations
Unveiling a Hidden Gem: Gio Ponti's Villa Namazee in Tehran (1957 - 64)
No full textLAUREA MAGISTRALECostruita dal celebre architetto Gio Ponti (1891-1979), Villa Namazee è la terza ed ultima villa costruita da Ponti al di fuori del territorio europeo. Costruita tra il 1957 e il 1964, questa villa si trova a Teheran, in Iran, e segue temporalmente le ville Planchart e Arreaza, costruite in Venezuela. La villa fu commissionata a Ponti da Shafie Namazee, una figura di spicco della società aristocratica iraniana del periodo precedente alla Rivoluzione islamica. Tuttavia, con l’allontanamento dei proprietari dopo la Rivoluzione, la villa ha subito un processo di confisca ed espropriazione, per poi essere venduta a vari proprietari nel corso del tempo. Nel 2007 arriva il riconoscimento come patrimonio nazionale, status che verrà revocato nemmeno dieci anni dopo, nel 2016, per aprire la strada alla sua demolizione e alla sostituzione con un hotel di lusso di nuova costruzione. Di fronte all’opposizione di molteplici esponenti della cultura architettonica locale e internazionale, la villa è stata ripristinata come patrimonio nazionale nel marzo 2020, con un verdetto immutabile e insindacabile.
Per diversi anni, dopo la Rivoluzione, il destino di villa Namazee è rimasto incerto, con l’accesso alla villa limitato dai legittimi proprietari. Di conseguenza, le informazioni disponibili riguardanti l’edificio sono state per diverso tempo molto limitate o errate: basti pensare al susseguirsi di voci, fortunatamente infondate, che circolavano fino a pochi anni fa circa la demolizione dell’edificio (sorte invece sfortunatamente toccata a villa Arreaza). Dal punto di vista della letteratura architettonica esistente su Gio Ponti e le sue opere, villa Namazee è citata solo poche volte e sempre con dati ripetitivi e limitati.
Utilizzando documenti d’archivio, tra cui disegni, lettere e fotografie, nonché conducendo interviste e studi analitici e comparativi, questa tesi si propone quindi di far luce su un capolavoro meno noto e oscuro di Gio Ponti. Nei primi tre capitoli, l’autrice si confronta con il tema della committenza, domandandosi come un architetto italiano sia arrivato a progettare una villa privata in Iran, ripercorrendo il contesto storico, politico, culturale e architettonico dell’Iran e di Teheran durante il secondo governo Pahlavi. Inoltre, un approfondito studio del rapporto intercorso tra cliente e architetto è stato condotto attraverso l’analisi della corrispondenza d’archivio. Il quarto capitolo di questa tesi, centrale per la comprensione del lavoro di ricerca, si concentra sul percorso evolutivo di Villa Namazee a partire dagli anni della sua costruzione e documentando puntualmente le sue trasformazioni nel tempo, fino ad arrivare al suo stato attuale, attestato con fotografie e video inediti realizzati in occasione della visita alla Villa da parte dell’autrice nel settembre 2023.Villa Namazee, designed by the renowned Italian architect, Gio Ponti (1891-1979), was the third and last villa designed by Ponti outside the European borders. Constructed between 1957 and 1964, this villa is located in Tehran, Iran, after the previous villas of Planchart and Arreaza in Venezuela. The villa was commissioned by Shafie Namazee, a prominent figure in the aristocratic society of Iran before the Islamic Revolution. However, with its owners moving away after the revolution, it was confiscated, expropriated and sold to various owners over time. In 2007, it was recognized as a national heritage, but its status was revoked in 2016 to pave the way for its demolition and replacement with a luxury hotel. Facing opposition from local and international architectural communities, the villa was reinstated as a national heritage in March 2020 with this verdict being unchangeable even in the future.
For many years after the revolution, villa Namazee’s fate remained uncertain, as private owners restricted access to the property. Consequently, there has been limited information available regarding the villa which until a few years ago, many believed it to have been demolished like the unfortunate fate that faced villa Arreaza. In all the numerous, existing literature on Gio Ponti and his works, villa Namazee is mentioned only a few times and always with repetitive and limited data.
This thesis, aims to shed light on a lesser-known and obscure masterpiece of Gio Ponti, by using archival documents including drawings, letters and photographs, as well as conducting interviews and analytical and comparative studies. In the first three chapters, the author has tried to explain how an Italian architect came to design a private villa in Iran by going through the historical, political, cultural and architectural context of Iran and Tehran during the second Pahlavi rule. Additionally, the archival correspondences were studied to gain insights into the client-architect relationship. Moving forward, the fourth and central chapter of this thesis focuses on the evolutionary journey of villa Namazee from its construction years and transformations through time, arriving to its current state at the end which was achieved by author’s personal visit to the site in September 2023

Carbon dynamics and trophic relationships in a human impacted and mangrove dominated tropical estuary (Can Gio, Vietnam)
No full textLes estuaires à mangroves sont des écosystèmes très dynamiques qui transportent du carbone provenant des eaux continentales et de la production côtière vers la plaine d’inondation, et exportent vers l’océan une partie de celui fixé par la végétation environnante. Les mangroves sont des écosystèmes très productifs et servent ainsi de zones de nurserie et d’alimentation pour de nombreuses espèces côtières qui y pénètrent lors de la marée montante et exportent lors de la marée descendante la matière qu’ils y ont ingérée. Cependant, les quantités et la qualité du carbone qui est échangé dans l’estuaire, ainsi que les transformations qui s’y opèrent, sont encore mal connues. Ce travail de thèse a pour objectif d’étudier le cycle du carbone dans l’estuaire traversant la mangrove de Can Gio, au sud du Vietnam, ainsi que les organismes macroscopiques connectant la mangrove au compartiment océanique par leurs déplacements ; ceci, afin de mieux comprendre le bilan de carbone de la mangrove de Can Gio, et plus largement, celui des mangroves tropicales. Les résultats présentés sont issus de 3 campagnes d’échantillonnage ; la première en saison sèche, uniquement le long de l’estuaire traversant la mangrove ; la deuxième en saison humide, le long de l’estuaire et dans un chenal de vidange ; et la dernière afin de simuler en laboratoire le devenir d’effluents crevetticoles une fois rejetés dans l’estuaire. Des suivis des masses d’eau ont été effectués en différentes zones du réseau hydrographique de la mangrove, à chaque fois au cours d’un cycle tidal complet (24 h), et diverses espèces macroscopiques ont été capturées dans le lit mineur et la zone intertidale. Cette étude s’intéresse à la fois aux formes minérales du carbone, notamment le CO2 qui joue un rôle clé dans la régulation du climat, à ses formes organiques, en particulier les acides gras qui sont utilisés comme traceurs de la matière organique dans les réseaux trophiques et qui possèdent de nombreuses fonctions métaboliques, et enfin à des spécificités du compartiment microbien, qui contribue au remaniement de ce carbone.Mangrove estuaries are highly dynamic environments importing carbon originating from both the watershed and the coastal ocean to the adjacent floodplain, and exporting to the ocean a fraction of that photosynthesised by the surrounding vegetation. Mangroves are very productive ecosystems. Thus, they serve as a nursery for a wide variety of coastal species entering the ecosystem during flood, and exporting during ebb the carbon they consumed. However, the quantities and the quality of carbon exchanged within the estuary, along with the transformations occurring during the water transit, are still not fully understood. This work aims to examine the carbon cycle in the main estuarine channel of the Can Gio mangrove, located in southern Vietnam, along with macroscopic species connecting the mangrove ecosystem to the coastal ocean through their movements; this, in order to better understand the carbon budget of the Can Gio mangrove, and at a broader scale, of tropical mangroves. Results presented in this manuscript are originating from 3 sampling campaigns; the first performed during the dry season, along the main estuarine channel only; the second achieved during the wet season, along both the main estuarine channel and a mangrove tidal creek; and the last in order to simulate in controlled conditions the fate of shrimp pond effluents once released in the estuary. Water column parameters were surveyed at different sites located on the mangrove waterways, each during a complete tidal cycle (24 h), and various macroscopic species were sampled from both the intertidal zone and the water column. This study examines concomitantly mineral forms of carbon, particularly CO2, which plays a major role in climate mitigation; its organic forms, especially fatty acids, used as biomarkers in trophic webs studies and implied in diverse metabolic functions; and specificities of the microbial compartment, contributing to the cycling of this carbon
