Product-type operators between minimal M\"{o}bius invariant spaces and Zygmund type spaces
In this paper, we consider product-type operators from
minimal M\"{o}bius invariant spaces into Zygmund type spaces. So some
characterizations for boundedness and essential norm of these operators are
obtained. As a result some conditions for the compactness will be given
Developing a Decision Support System for Integrated Decision-Making in Purchasing and Scheduling under Lead Time Uncertainty
Decision-making in supply chain management is complex because of the relations between planning tasks from different stages and planning levels. Uncertainties such as unpredictable supplier lead times and supply chain disruptions further complicate decision-making. Considering the case study of a company in printed circuit board assembly, a three-level concept is proposed that includes a decision support system. The global single-source supply network is characterized by highly variable lead times. Hence, the company maintains high inventory levels to prevent running out of stock. The decision support system considers the purchasing and scheduling decision problems in an integrated way. The prototypical implementation of the purchasing algorithm uses a genetic algorithm that recommends reorder days and order quantities using a simulation model. In addition, it evaluates the risks of the recommended solution by calculating the probability of stockouts for each order cycle
広島大学考古学研究室所蔵の西アジア青銅柄鉄剣をめぐって
いわゆる「鉄芯」入り青銅剣(バイメタル青銅剣)とされてきた広島大学考古学研究室所蔵資料についての再調査を行う。バイメタル青銅剣は、紀元前800~1200ごろ年にカスピ海南部の山岳地帯において出現する金属器で、鉄利用の初期の様相を明らかにするうえで重要である。西アジア北部地域における鉄製利器の祖型として、鉄製棒状部品を内蔵する青銅剣(「鉄芯」入り青銅剣)の存在が指摘され、編年・機能研究が行われてきた。しかし、当該資料はおそらく現代において改変された青銅柄鉄剣であったことが判明した。他機関所蔵品の知見も加味すると、研究対象の多くに同様の可能性があり、「鉄芯入り」青銅剣を前提に導かれたこれまでの知見や議論は根本的な見直しを迫られることになる。紀元前2000年紀の終わりにカスピ海周辺に出現する「鉄芯入り」青銅剣が実は青銅柄鉄剣であったわけであり、それ以前に鉄製利器の導入期といった、より原初的な初期鉄器の実態がある可能性が高くなる。今回の再調査はそうした研究の脆弱性を露呈し、西アジアにおける初期鉄器時代の議論を転換する結果となった
"Go Tell the Assyrians, Thou Who Passest By, That Here, Obedient to Their Laws, We Lie..."
This paper deals with a topic hardly studied by our fellow scholars: the management of casualties during the aftermath of a victorious battle for the Neo-Assyrians. The paper will propose a typology of casualties according to different points of their different kinds of status, plus some questions on some problems still encountered by modern soldiers nowadays
Missing Links: Demic Diffusion and the Development of Agriculture on the Central Iranian Plateau
This thesis studies the development of agricultural settlements on the Central Iranian Plateau during the Neolithic and Chalcolithic periods. To date, no Early Neolithic sites (ca. 8000-6500 BC) are known on the Central Plateau. This thesis aims to establish whether there was an Early Neolithic presence on the Central Plateau through taking a combined approach involving: a review of the current information available on the Neolithic of Iran and surrounding areas; the re-calibration and chronometric hygiene evaluation of existing radiocarbon determinations for Neolithic sites in Iran and neighbouring areas in order to map the ‘spread’ of agriculture; and the analysis of new data from recent archaeological research the Central Iranian Plateau. In studying the development of agriculture on the Central Iranian Plateau this thesis will provide valuable information on the origins and spread of agriculture in Central and South Asia, a region which has received relatively little archaeological attention in comparison to Europe. In particular, this research will elucidate whether the prevalent model for the spread of agriculture across Europe – Ammerman and Cavalli-Sforza’s (1984) ‘Wave of Advance’ – is equally applicable to Central Asia, as has been suggested by Renfrew (1987), but never explicitly tested. As this research utilises both new and old data and provides both temporal and spatial perspectives, it represents an original study of the prehistoric period on the Central Iranian Plateau
La diosa de Galera, fuente de aceite perfumado
The Goddess from Galera was found in a tomb of the Iberian cemetery of Tutugi (Granada) dated c. 450 BC with a structure similar to the royal tomb of Pozo Moro. The Galera-Goddess is an alabaster sculpture dated in the VIII BC. from a Syrio-Phoenician workshop. It was a sacred vase for perfumed oil, devoted to the ritual anoint of god sculptures and sacred kings.
The vase represents the goddess Astart, seated in her throne between two sphinxes and conceived as the Tree of Life. From her breasts come out the sacred perfumed oil which give life to the King, protect him magically and give him the Everlasting Life, as shown in oriental texts and iconography. Thereafter, it was not a keimélion brought trough Phoenicians trade, but a sacred object arrived to the Far West from a Nord-Syrian royal context trough the koiné of the Phoenician colonisation. As it was found in an Iberian royal tomb, it documents the origin of the ideology and ritual from the Tartessian and Iberian kings in the Orientalaizing Period.La llamada Diosa de Galera apareció en una tumba real de la necrópolis ibérica de Tutugi (Granada), comparable a la de Pozo Moro, aunque de mediados del siglo V a.C. Es una escultura de alabastro labrada en un taller áulico sirio-fenicio del siglo VIII a.C. para servir como vaso sagrado de aceite perfumado destinado en exclusiva a la unción ritual de estatuas de divinidad y/o de reyes divinizados.
La diosa Astart, entronizada entre dos esfinges, aparece concebida como Árbol de la Vida, pues de sus pechos brota el divino néctar o ambrosía perfumado que da al Rey la vida, le protege mágicamente y le garantiza la vida eterna en el Más Allá, según indican textos y representaciones orientales.
Se trata de un objeto ritual sacro de ámbito regio, no de un simple keimélion traído por los fenicios. Sería la divinidad protectora de algún miembro de estirpe real nordsirio llegado a Occidente a través de la koiné colonial fenicia. Su aparición en una tumba real de Hispania documenta cómo se debió conformar la ideología y el ritual de las elites regias de Tartessos y del mundo ibérico en el Periodo Orientalizante
Estimating the maximum earthquake magnitude in the Iranian Plateau
The Iranian Plateau has been subjected to destructive earthquakes throughout its history. Reliable assessment of the seismic hazard in this earthquake-prone region is therefore essential. Our study focuses on estimating the maximum earthquake magnitude as one of the main parameters of seismic hazard analysis. We implemented two quantitative approaches, namely, probabilistic and deterministic. The probabilistic method allows combining the historical (i.e. incomplete) and the instrumental parts of a catalogue with different levels of completeness and considers the uncertainties in earthquake magnitude determination. In this study, we used a unified, declustered, and complete catalogue of earthquakes in Iran, covering the period from the fourth century BC to 2019. We calculated the maximum possible magnitudes for hundreds of grid points by using the seismicity data in a 200-km radial region around each grid point. The maximum possible earthquake was observed to vary between 6.0 and 8.2, and the highest values were found in the Alborz-Azarbayejan seismotectonic province, Kopeh-Dagh, central east Iran, Makran, and the southeast Zagros. The lowest mmax values were found in the Persian Gulf, Arabian Platform, Esfahan-Sirjan region, and the Dasht-e-Kavir Desert in central Iran. As a second part to this study, we calculated the maximum credible earthquakes for 1103 identified major faults by using five empirical magnitude-scaling relationships. Our results were consistent with both the observed earthquakes and the seismic potential of the various seismogenic zones of Iran. The study results can be used in future seismic hazard analyses and have fundamental implications for mitigating seismic risk in Iran.http://link.springer.com/journal/10950hj2022Geolog
Mobility and economic transition in the 5th to the 2nd millennium B.C. in the population of the Central Iranian Plateau, Tepe Hissar
Iranian archaeology has had a keen interest in exploring unexplained events occurring during the 5th to the 2nd millennium B.C. on the Central Iranian Plateau. This is represented by transformations in material culture, a differentiation in mortuary practices, and site abandonment and reoccupation, and has traditionally been explained by the influx of new populations into Central Plateau sites. The site of Tepe Hissar, the subject of this research, located in the north-east region of the Central Plateau and appears to have undergone these changes during its existence (late 5th to the early 2nd millennium B.C.). This research uses a bioarchaeological approach to tests the hypotheses that the socio-cultural-economic changes that occurred at Tepe Hissar over time, accompanied by influxes of new people into the site, particularly in Hissar periods II and III; ultimately impacted on subsistence economy, diet, and general health, and also resulted in a rise in tension and interpersonal violence.
The biological affinity data suggest that the changes at Tepe Hissar were not accompanied by large scale population replacement/immigration/or invasion. Rather, there was more small scale population replacement over time, although these changes were accompanied by interpersonal violence. These changes did not greatly impact on the general health of people over time, although people in each period experienced different frequencies of stress and disease, and periods of malnutrition; both females and males were affected equally in each period.
The dental disease data showed that changes during Hissar II and III had a significant impact on the oral-health of people, and Hissar I experienced better oral-health compared to later periods; this may be due to changes in subsistence economy and diet, food preparation techniques, and how the teeth were used as tools. The data indicate that males possibly suffered poorer dental health compared to females at this site; they may have had a different diet, or possibly used their teeth as a third hand more than females.
The isotopic data (C/N) showed that the inhabitants had access to similar food resources across all periods; individuals from each period, both sexes from different age-categories, had a similar diet based on C3 plants and animal protein, as well as a small contribution from fresh water resources.
Overall, this research suggests that the society who lived at Tepe Hissar overall may have had an appropriate social structure and adequate food resources to withstand socio-cultural-economic changes, enabling the community to be more centralised socially, economically, and politically such that the changes and events they experienced did not markedly affect their health or nutritional status
