Exploiting Data Analytics and Deep Learning Systems to Support Pavement Maintenance Decisions
2021
Road networks are critical infrastructures within any region and it is imperative to maintain their conditions for safe and effective movement of goods and services. Road Management, therefore, plays a key role to ensure consistent efficient operation. However, significant resources are required to perform necessary maintenance activities to achieve and maintain high levels of service. Pavement maintenance can typically be very expensive and decisions are needed concerning planning and prioritizing interventions. Data are key towards enabling adequate maintenance planning but in many instances, there is limited available information especially in small or under-resourced urban road authorit…
Zdolności logistyczne w kształtowaniu obsługi klienta
2022
Wciąż rosnąca konkurencja skłania przedsiębiorstwa do poszukiwania źródeł przewagi konkurencyjnej. Istotnym elementem tworzenia tej przewagi jest obsługa klienta. Właściwie realizowana obsługa klienta pozwala osiągnąć satysfakcję i zadowolenie klienta, co umożliwia tworzenie i utrzymywanie przewagi konkurencyjnej. Jednym ze sposobów właściwego kształtowania obsługi klienta są zdolności przedsiębiorstw, w tym zdolności logistyczne. Celem artykułu jest przedstawienie znaczenia zdolności logistycznych w kształtowaniu obsługi klienta. W artykule przedstawiono (1) koncepcję zdolności logistycznych, (2) istotę, fazy i elementy obsługi klienta, (3) transformację podejścia do obsługi klienta w kier…
Logistics potentials of success as the factors affecting firm performance
2019
Firms are permanently looking for ways to achieve expected market and economic outcomes, which are the basis for superior performance as well as strong, long-term competitive advantage. The most important market outcomes are: (1) customer satisfaction, (2) customer loyalty, and (3) marketshare. In turn, the most important economic outcomes are: (1) profit, (2) profitability, and (3) return on investment (ROI). In achieving such performance and advantage the important role is assigned - among others - to the so-called logistics potentials of success. Logistics potentials of success are significant parts of the “general” firm potentials of success, which comprise: (1) resources, (2) capabilit…
Selected methods of location logistic distribution centers in food supply chains
2020
W pracy przedstawiono jedną z wielu prezentowanych w literaturze przedmiotu metodę wyboru lokalizacji logistycznego centrum dystrybucyjnego w łańcuchach dostaw żywności. Metoda ta rozpatruje problem wyboru lokalizacji w aspekcie kosztów całkowitych lub czynnika przestrzeni, a dokładniej – odległości. W pracy przedstawiono możliwość zastosowania tej metody. W tym celu przedstawiono krótki przegląd literatury, następnie na końcu artykułu pokazano możliwość zastosowania metody do rozwiązania problemu.
ANALISI GIS E MODELLI STATISTICI PER LA VALUTAZIONE DELLA SUSCETTIBILITÀ DA FRANA A SCALA DI BACINO: IL CASO STUDIO DEL BACINO DEL TORRENTE MARVELLO
Lo studio condotto nel presente lavoro di tesi ha affrontato il tema della valutazione, a scala di bacino idrografico, della suscettibilità ai fenomeni di tipo colamento, attraverso l’applicazione di modelli statistici e tecniche di analisi spaziale GIS. La fase iniziale della preparazione di un modello di suscettibilità da frana prevede la realizzazione di un inventario degli eventi verificatesi nell’area di studio. Questo passo è di fondamentale importanza, considerando che proprio attraverso l’archivio frane è possibile analizzare ed individuare le condizioni che in passato hanno favorito l’innesco dei movimenti di versante. L’identificazione di queste condizioni, infatti, consente di pr…
Analisi comparativa di modelli euristici e statistici spaziali nella derivazione della suscettibilità da colate rapide di fango e detrito.
2013
La suscettibilità da frana può essere definita come la propensione di una determinata area all’innesco di movimenti di massa, in relazione alle caratteristiche intrinseche dei terreni di copertura e del substrato, delle caratteristiche morfologiche ed alla maggiore esposizione nei confronti degli agenti climatici. Nel corso degli anni sono stati sviluppati vari metodi per valutare la suscettibilità, basati su approcci sia di tipo deterministico che statistico. Tutti i metodi si basano su poche assunzioni fondamentali secondo cui la franosità è controllata da leggi meccaniche che possono essere determinate in modo empirico, statistico o deterministico. Scopo del presente lavoro è quello di v…
Methodological advances in the functional profiling of genomic studies
2013
In this thesis we present bioinformatic tools and algorithms for the analysis of genomic data such as those generated by microarray devices or next generation sequencing techniques. Particularly, we develop new approaches to gene set analysis. The described procedures should be useful in practice to tackle complex biological experiments, but hopefully will also be methodologically relevant, as they introduce new ways of conceptualizing genomic functional profiling. Our very flexible approach allows for the inclusion of not just one kind of genomic measurement but many. It makes possible, for instance, to analyze expression measurement and genomic variation data at a time. This multidimensio…
Neighborhood Mobility and Unmet Physical Activity Need in Old Age: A 2-Year Follow-Up
2020
Background: Many older people report a willingness to increase outdoor physical activity (PA), but no opportunities for it, a situation termed as unmet PA need. The authors studied whether lower neighborhood mobility and PA precede the development of unmet PA need. Methods: Community-dwelling 75- to 90-year-old people (n = 700) were interviewed annually for 2 years. Unmet PA need, neighborhood mobility, and PA were self-reported. In addition, accelerometer-based step counts were assessed among a subgroup (n = 156). Results: Logistic regression analyses revealed that lower baseline neighborhood mobility (odds ratio 3.02, 95% confidence interval [1.86, 4.90] vs. daily) and PA (odds ratio 4.37…
Forward logistic regression for earth-flow landslide susceptibility assessment in the Platani river basin (southern Sicily, Italy)
2013
Forward logistic regression has allowed us to derive an earth-flow susceptibility model for the Tumarrano river basin, which was defined by modeling the statistical relationships between an archive of 760 events and a set of 20 predictors. For each landslide in the inventory, a landslide identification point (LIP) was automatically produced as corresponding to the highest point along the boundary of the landslide polygons, and unstable conditions were assigned to cells at a distance up to 8 m. An equal number of stable cells (out of landslides) was then randomly extracted and appended to the LIPs to prepare the dataset for logistic regression. A model building strategy was applied to enlarg…
Relevance of trade facilitation in emerging countries exports
2012
The objective of this article is to analyse trade flows in emerging nations with a maritime boundary, where trade facilitation plays a decisive role in their international development. In order to detect possible patterns in performance, we apply the economic approach of gravity models using the World Bank Logistic Performance Index (LPI) as a good proxy of trade facilitation. The results of the estimation lead to the conclusion that the more complex the transportation of goods is, the more influential the logistics indicator, trade facilitation being most prominent in Middle East exporters.
