real time assistance to manual assembly through depth camera and visual feedback
Abstract The current fourth industrial revolution significantly impacts on production processes. The personalized production paradigm enables customers to order unique products. The operators assemble an enormous component variety adapting their process from product to product with limited learning opportunities. Digital technologies are increasingly adopted in production processes to improve performance and quality. Considering this framework, this research proposes a hardware/software architecture to assist in real-time operators involved in manual assembly processes. A depth camera captures human motions in relation with the workstation environment whereas a visual feedback guides the operator through consecutive assembly tasks. An industrial case study validates the architecture
Syncope in the elderly: An update
Abstract Syncope in the elderly is an extremely prevalent clinical condition characterized by high mortality and presence of recurrences. The diagnosis of syncope in the elderly is sometimes difficult and multidimensional geriatric assessment should be carefully administered. Diagnostic algorithms should be applied with attention, although unknown syncope is still frequent. The therapeutic approach to syncope in the elderly is complicated by the high prevalence of neurally-mediated syncope, in which the therapeutic approach is still unknown. The establishment of a "Syncope Unit" has certainly improved the diagnostic-therapeutic approach to patients with syncope, especially in old age where the management is extremely difficult
A multimodal approach for tracing lateralization along the olfactory pathway in the honeybee through electrophysiological recordings, morpho-functional imaging, and behavioural studies
Recent studies have revealed asymmetries between the left and right sides of
the brain in invertebrate species. Here we present a review of a series of
recent studies from our labs, aimed at tracing asymmetries at different stages
along the honeybee's (Apis mellifera) olfactory pathway. These include
estimates of the number of sensilla present on the two antennae, obtained by
scanning electron microscopy, as well as electroantennography recordings of the
left and right antennal responses to odorants. We describe investigative
studies of the antennal lobes, where multi-photon microscopy is used to search
for possible morphological asymmetries between the two brain sides. Moreover,
we report on recently published results obtained by two-photon calcium imaging
for functional mapping of the antennal lobe aimed at comparing patterns of
activity evoked by different odours. Finally, possible links to the results of
behavioural tests, measuring asymmetries in single-sided olfactory memory
recall, are discussed.Comment: 28 pages, 8 figure
[Comparison of computerized tomography and sialography in diagnosis of parotid cysts].
In this study it has been valued the differences between T.C. and "scialography" in the parotid gland cystic lesions. Between 1986 and 1987 we examined 100 patients affected by parotid gland diseases utilizing the two different techniques. In 7 patients we diagnosed cystic lesions of parotid gland. Afterwards we compared the results obtained by T.C. and by scialography
Role of Ventricular Rate Response on Dementia in Cognitively Impaired Elderly Subjects with Atrial Fibrillation: A 10-Year Study
The role of ventricular rate response (VRr) on the incidence of dementia in elderly subjects with cognitive impairment and atrial fibrillation (AF) is not known. Thus, we examined the ability of VRr to predict dementia in cognitively impaired elderly subjects with and without AF.
A total of 358 cognitively impaired elderly subjects (MMSE 50/<90 bpm) VRr. A 10-year follow-up was performed.
Cognitively impaired subjects with dementia at the end of the follow-up were 135 (37.7%): 33 in the presence (75.0%) and 102 (32.5%) in the absence of AF (p < 0.001). Multivariate analysis shows that AF is a strong predictor of dementia (hazard ratio, HR = 4.10; 95% confidence interval, CI = 1.80-9.30, p < 0.001). More importantly, low/high VRr ( 90 bpm) is predictive of dementia in the presence (HR = 7.70, 95% CI = 1.10-14.20, p = 0.03) but not in the absence (HR = 1.85; 95% CI = 0.78-4.47; p = 0.152) of AF.
This study demonstrates that AF predicts dementia in elderly subjects with cognitive impairment. Moreover, VRr seems to play a key role in the incidence of dementia in cognitively impaired elderly subjects with AF
