Measuring and analyzing German and Spanish customer satisfaction of using the iPhone 4S Mobile Cloud service
No full textThis paper presents the customer satisfaction analysis for measuring popularity in the Mobile Cloud, which is an emerging area in the Cloud and Big Data Computing. Organizational Sustainability Modeling (OSM) is the proposed method used in this research. The twelve-month of German and Spanish consumer data are used for the analysis to investigate the return and risk status associated with the ratings of customer satisfaction in the iPhone 4S Mobile Cloud services. Results show that there is a decline in the satisfaction ratings in Germany and Spain due to economic downturn and competitions in the market, which support our hypothesis. Key outputs have been explained and they confirm that all analysis and interpretations fulfill the criteria for OSM. The use of statistical and visualization method proposed by OSM can expose unexploited data and allows the stakeholders to understand the status of return and risk of their Cloud strategies easier than the use of other data analysis
Brain Segmentation ? A Case study of Biomedical Cloud Computing for Education and Research
No full textMedical imaging is widely adopted in Hospitals and medical institutes, and new ways to improve existing medical imaging services are regularly exploited. This paper describes the adoption of Cloud Computing is useful for medical education and research, and describes the methodology, results and lesson learned. A working Bioinformatics Cloud platform can demonstrate computation and visualisation of brain imaging. The aim is to study segmentation of brains, which divides the brain into ten major regions. The Cloud platform has these two functions: (i) it can highlight each region for ten different segments; and (ii) it can adjust intensity of segmentation to allow basic study of brain medicine. Two types of benefits are reported as follows. Firstly, all the medical student participants are reported to have 20% improvement in their learning satisfaction. Secondly, 100% of volunteer participants are reported to have positive learning experience
Some Observations on the Construction of Space in the Prose of W. G. Sebald
No full textPierwodruk: „Białostockie Studia Literaturoznawcze” 2016, nr 8.This essay discusses the relationship between how space is constructed in the works of W. G. Sebald, and a fundamental characteristic of his texts, namely their hybridity. The author focuses, in particular, on the function of photography in Sebald’s narrations. Photographs, though themselves iconographic signs with strong referentiality, do not eliminate a strong textualization of space in Sebald’s works.Katedra Teorii Literatury, Uniwersytet Łódzki814115
Zawartosc fosforu i jego frakcje w pomiocie brojlerow
No full textPrzeanalizowano pomioty brojlerów pochodzące z doświadczenia żywieniowego, którego celem było zbadanie wpływu dodatku fitazy do czterech rodzajów paszy: śruty pszennej, śruty jęczmiennej, wytłoku rzepakowego i śruty poekstrakcyjnej na strawność fityny. W badanych próbkach oznaczono: całkowitą zawartość fosforu po mineralizacji „na mokro”, zawartość fosforu fitynowego poprzez ekstrakcję i wytrącanie fityny w formie fitynianu żelaza, a następnie jej mineralizacji „na mokro” oraz zawartość mineralnych frakcji fosforu metodą Jacksona i Changa w modyfikacji Petersona i Corey’a. Zawartość fosforu mineralnego obliczono jako sumę fosforanów mineralnych. Całkowita zawartość fosforu wahała się w granicach 10,32 - 18,15 g P·kg⁻¹ s.m. pomiotu, dodatek fityny do paszy obniżył udział fosforu fitynowego w pomiotach. Zawartość fosforanów rozpuszczalnych w wodzie wahała się w granicach 31,32% (wytłok rzepakowy) - 81,85% (śruta jęczmienna z dodatkiem fitazy) całkowitej zawartości fosforu pomiotów kurzych. Udział fosforanów glinu wahał się w granicach 2,51% (śruta jęczmienna z dodatkiem fitazy) - 9,46% (wytłok rzepakowy z dodatkiem fitazy) fosforu całkowitego, a fosforanów żelaza (III) 0,73 - 3,13%. Nie stwierdzono obecności frakcji fosforanów okludowanych. Dodatek fityny do paszy zwiększył procentowy udział frakcji fosforu mineralnego w całkowitym, a także procentowy udział fosforanów rozpuszczalnych w wodzie w odniesieniu do zawartości frakcji fosforu mineralnego.The droppings of broiler chicks got from the feeding experiment including four kinds of poultry feeds, with and without addition of phytase, were analysed for the contents of phosphorus and its fractions. The contents of: total phosphorus (1) was determined in „base solution” obtained after wet mineralization by spectrophotometric method; phosphorus in phytin (2) was determined after exraction of phytin, precipitation with Fe³⁺ and wet mineralization; the mineral phosphorus forms (3) were determined by Jackson and Chang method in Peterson and Corey’s modification. The content of phosphorus in mineral forms was calculated as a sum of particular mineral compounds.
The content of total phosphorus ranged from 10.32 to 18.15 g P·kg⁻¹ DM. Addition of phytin to the feeds decreased the concentration of phytin phosphorus in broiler droppings. The concentration of phosphate dissoluble in water in the manure ranged from 31.32% (after feeding with rape seed oil cake) to 81.85% (after feeding with ground barley grain with phytase addition) in relation to total concentration of phosphorus in poultry manure. The percentage of mineral phosphate in total phosphorus concentration was as follow: aluminium phosphate ranged from 2.51% (droppings after feeding with ground barley grain plus phytase) to 9.46% (droppings after feeding with rape seed oil cake plus phytase), iron III phosphate ranged within 0.73 - 3.13%. The addition of phytin to feeds increased percentage of mineral phosphate in total content of phosphorus as well as the percentage of phosphate dissoluble in water, in relation to mineral phosphate
High cell density cultivation of Escherichia coli W using sucrose as a carbon source
No full textEscherichia coli W was cultivated in the pH-stat fed-batch mode in a chemically defined medium containing sucrose as a sole carbon source. A final cell concentration of 105 g/L could be obtained in 36 hrs by feeding 20 g sucrose+0.57 g MgSO47H2O for a definite on-time upon the pH rise. Using the same strategy, a recombinant strain harboring pSYL104 could also be grown to 125 g/L in 48 hrs

Effective soundscape characterisation of an acoustic metamaterial based window: A comparison between laboratory and online methods
No full textQualitative investigation of the sound environment from human perception has lately reached wider attention through psychophysical and Soundscape descriptors; However, laboratory or in situ questionnaire can only reach a limited amount of demographic backgrounds, as, in a limited variety of cultural and geographical variation in a medium-short time, risking to bias/influence the results of the analysis. Starting from a related paper, the authors illustrated how to include human perception and psychoacoustics in evaluating an acoustic metawindow (AMW) unit effectiveness. This paper investigates the robustness of the mixed laboratory and online methodology and proves the validity of the exclusively online-based soundscape questionnaire method according to a number of headset setups. For this reason, a first Laboratory experiment with a fixed and controlled setup was followed by an Online 1 experiment, where the same participants took the same questionnaire (with a three weeks' time difference). Finally, the Online 2 experiment was used to broaden the sample background (results concerned the online method only). The setups mostly influenced the participants' responses by neutralising it (in 48% of the cases) while reporting a rate with an acceptable error (45% of Δrate = 0/5 and 39% of Δrate = 1/5). Wired headphones based rates agreed with the laboratory one consistently (36% of Δrate = 0 and overall CV = 2–25% through soundscape descriptors). Wired earphones had a similar Δrate percentage but with an overall more neutralised soundscape perception (overall CV = 1–40% compared with Laboratory rates). Wireless earphones caused the extremer Δrate (54% of Δrate = 3). Finally, natural and human noises are more detectable spontaneously, while traffic or other artificial noise are mostly recognised when directly addressed to the participants. This additional analysis gives more precise information about how efficient is the online method compared to the laboratory one. If accounted accordingly, an online-based soundscape questionnaire setup could also be viewed as a solid alternative to grasp a wider range of human perception points of view according to a broader cultural and geographical background
Oddanie czci kurzowi. W. G. Sebald i czytanie w tropach
No full textFew writers paid as much attention to dust as W. G. Sebald. The author of Austerlitz saw in it „the lowest sign of annihilation” and a “boundary between being and nothingness,” an elegiac way of making the dead present in the text. For Sebald, all the ways of reading the past were “reading (in) dust,” making this particular way close to prophesying. The author of the essay follows Sebald’s opinion, tracing various forms and manifestations of the “prophetic epistemological paradigm.” Reading the irregular, reading „what has never been written,” has also its political aspect of (re)thinking the past from the remains of destruction. This is how dust becomes critical and subversive matter
