Using Microsoft Power BI for sales forecasting as a data mining technique
No full textThis study aims to predict the sales of a commercial organization in order to know the role that modern information technology plays in achieving accurate and rapid processing of data based on the data mining tool represented in the Microsoft Power BI business intelligence program, through a theoretical and applied study. The significant role played by the estimated future sales information in the planning process as well as guiding and rationalizing the decisions of the sales manager to improve the performance of the organization
Factors influencing immediate post-angiographic occlusion outcomes in intracranial aneurysms treated with the woven endobridge device: a multi-center analysis and predictive model from the WorldWideWEB consortium
No full textThe Woven EndoBridge (WEB) device treats wide-necked bifurcation aneurysms, but occlusion rates vary. This study aims to identify factors associated with immediate WEB device occlusion. Data from patients treated with WEB devices across 36 sites were analyzed. Machine learning algorithms and ordinal regression models were developed to predict immediate incomplete occlusion for ruptured and unruptured aneurysms. The study included 1565 patients, with 436 ruptured and 1129 unruptured aneurysms. Immediate complete occlusion was achieved in 38.3% of ruptured and 32.8% of unruptured aneurysms. For ruptured aneurysms, the CatBoost classifier achieved an AUROC of 0.69. Key predictors of incomplete occlusion included pretreatment mRS, aneurysm diameter, and MCA location. Ordinal regression revealed that smoking history (OR: 1.95, p < 0.001), neck diameter (Odds Ratio [OR]: 1.50, p < 0.001), and presence of a branch from the aneurysm (OR: 2.06, p = 0.016) were associated with incomplete, while bifurcation aneurysms (OR: 0.55, p = 0.017) were associated with complete immediate occlusion. For unruptured aneurysms, the CatBoost classifier achieved an AUROC of 0.68. Significant predictors of immediate incomplete occlusion included aneurysm neck width, MCA location, and presence of daughter sac. Ordinal regression revealed that smoking history (OR: 1.29, p = 0.032), neck diameter (OR: 1.24, p < 0.001), and presence of a daughter sac (OR: 1.53, p = 0.005) were associated with incomplete, while bifurcation aneurysms (OR: 0.71, p = 0.02) and posterior circulation location (OR: 0.68, p = 0.01) were associated with complete immediate occlusion. Careful evaluation of patient demographics and specific aneurysm characteristics may help improve the outcomes of intracranial aneurysms treated with WEB device.

A study of the language of selected 15th and 16th century aljamiado manuscripts.
No full textPhDThis thesis consists of a survey of the linguistic features
of datable aljamiado manuscripts, taken as nearly as possible
at twenty year intervals from 1429 to 1597, with the purpose of
ascertaining to what extent Morisco writings in Arabic character
shed any light on contemporary Spanish pronunciation and whether
any chronology of sound-change in Castilian can be recorded from
the collated evidence. The chief features examined are initial
F-, the sibilants, the plosive and fricative value of d and the
possibility of early instances of yeïsmo. On the whole it has been
found that the Moriscos were not innovators and the language of
even late sixteenth-century manuscripts still shows forms current
at the beginning of the century. The thesis includes transcriptions
of extracts from MSS. B.N.5319, J.1, B.N.5073/6/7/12, B.N. 4908/1,
B.N. 5364, T.13, T.16, B.N.5223 and J.30. There is also a Glossar
