Demo abstract: Cross-technology TDMA synchronization using energy pattern beacons

2017

When different technologies use the same frequency bands in close proximity, the resulting interference typically results in performance degradation. Coexistence methods exist, but these are often technology specific and require technology specific interference detection methods. To remove the root cause of the performance degradation, devices should be able to negotiate medium access even when using different technologies. To this end, an architecture that allows cross-technology medium access by means of a Time Division Multiple Access (TDMA) scheme was devised. In order to achieve cross-technology synchronization, which is required for the TDMA solution, an energy pattern beacon is trans…

Reclutamiento y reclutas en la ciudad de Valencia (1717-1762)

2019

This research aims to analyze recruitment by quintas, Spanish word for recruitment levies by lot, in the city of Valencia and the townships included in its jurisdictional area. The analyzed period began in 1717 with the first levie decreted by king Philip V once the War of Spanish Succession was over. Applied this levie in the kingdom of Valencia, this was the first application of levies by lot. The closing year for the reported period up to 1762, whith the last levy made by king Charles III before the establishment of the annual periodicity for the recruitment process. Procedures with which human contingents claimed to the city of Valencia between the mentioned dates were organized and dis…

Cold tolerance during larval development: effects on the thermal distribution limits of Leptinotarsa decemlineata

2009

Insects' cold tolerance during their development is a surprisingly understudied subject in ecology, despite the fact that subzero temperatures during the growing season are common at high altitudes and latitudes. Subzero temperatures can have detrimental effects on organisms, restricting a species' range. This study addresses the question whether night frosts during the growing season have an instant or delayed negative impact on larval mortality of the Colorado potato beetle, Leptinotarsa decemlineata (Say) (Coleoptera: Chrysomelidae). We also tested whether populations from the centre (Poland) and margins (Russia) of the distribution range of L. decemlineata differ in their responses to s…

Poleward range expansion without a southern contraction in the ground beetle Agonum viridicupreum (Coleoptera, Carabidae)

2011

We investigated the extent of poleward shifts in the distribution range of Agonum viridicupreum due to climate change in the western Palaearctic. Species' records were obtained from extensive literature sources as well as from collections, and consistent amateur entomologists' recordings. Within the general geographic range of the species, we analyzed in detail two parts of both, the northern and southern distribution range boundaries: (1 and 2) north-western Germany (leading or high-latitude edge), (3) Israel and (4) southern Italy (rear or low-latitude edge). Temporal changes in the occurrence data of the species indicated a northward shift of the leading edge of a minimum of 100 km withi…

New Insights into the Functional Morphology of the Lever Mechanism of Salvia pratensis (Lamiaceae)

2007

† Background and Aims The functional morphology of Salvia pratensis flowers was re-investigated, after new insights revealed that pollen dispensing is one of the main functions of the staminal lever. In particular, no detailed information was available regarding the process of pollen transfer and the forces arising between the pollen-bearing thecae and the pollinating bee’s body. The assumption was made that these forces play a significant role in pollen dispensing. † Methods The functional morphology of S. pratensis flowers and the interaction between flowers and bees (Apis mellifera) were studied by reconstructing stress and strains by using qualitative and semi-quantitative theoretical a…

Kreacyjna zabawa z konwencją w "Listach" Michala Šandy do/i Karla Havlíčka Borovskiego

2020

Przedmiotem analizy jest niewielka książka zatytułowana Dopisy / Listy (2009) współczesnego pisarza Michala Šandy (1965), w której autor nawiązuje korespondencyjny dialog z Karlem Havlíčkiem Borovskim (1821–1856). Kreatywnie wykorzystuje w tym celu autentyczne listy, jakie czeski publicysta wysyłał z Brixen do brata Františka i splata je z półroczną relacją ze swojego życia opisywaną w konwencji realizmu magicznego. Dzięki wykorzystaniu motywu gry w scrabble oraz sięgnięciu po zasadę „ponownego napisania”, Šanda tworzy wielowarstwowy system odniesień, w którym znajdzie się m. in. miejsce dla Ernesta Hemingwaya. Ten swoisty dwugłos, zachowujący formalnie konwencję dyskursu epistolograficzneg…

Leo Tolstoy’s and Joseph Conrad’s Relation to Music

2017

It is important to stress that Tolstoy’s and Conrad’s texts are to be understood to include not only literary, and thus verbal, texts but also elements of other media, such as music, theatre and visual arts. It should be noted that for Conrad music was also one of the arts that he greatly appreciated. Though Conrad’s main concern was to make us “see,” he was also concerned with making us “hear.” The use of music to accompany sexual desire, frustration and violence is a technique often used by the writer. Likewise, music had an enormous infl uence on Tolstoy. He was fascinated with its power, just as with the power of sexuality, beauty and war. His favourite composer was Chopin, but he also …

Microbreweries, brewpubs and beerfirms in the Sicilian craft beer industry

2019

Purpose This paper aims to illustrate the organisational and managing models characterising the craft beer producers in Sicily (Southern Italy) and the main issues of the provision of raw materials. Design/methodology/approach A direct survey involving the overall population of 41 craft breweries operating in Sicily in 2016 was carried out. Then 29 questionnaires were collected for exploratory analysis. A hierarchical cluster analysis was also performed out to group companies by similar structural, productive and economic features. Findings The findings of the survey showed a Sicilian craft beer industry characterised by a substantial dependence on the import of malts hops and yeasts and t…
