SenseBoard: Sensor monitoring for air quality experts
Full text linkAir quality monitoring is crucial within cities since air pollution is one of the main causes of premature death in Europe. However, performing trustworthy monitoring of urban air quality is not a simple process. Especially, if you want to try to create extensive and timely monitoring of the entire urban area using low-cost sensors. In order to collect reliable measurements from low-cost sensors, a lot of work is required from environmental experts who deploy and maintain the air quality network, and daily calibrate, control, and clean up the data generated by these sensors. In this paper, we describe SenseBoard, an interactive dashboard created to support environmental experts in the sensor network control, management of sensor data calibration, and anomaly detection
Knowledge Graphs for Community Detection in Textual Data
No full textOnline sources produce a huge amount of textual data, i.e., freeform text. To derive insightful information from them and facilitate the application of Machine Learning algorithms textual data need to be processed and structured. Knowledge Graphs (KGs) are intelligent systems for the analysis of documents. In recent years, they have been adopted in multiple contexts, including text mining for the development of data-driven solutions to different problems. The scope of this paper is to provide a methodology to build KGs from textual data and apply algorithms to group similar documents in communities. The methodology exploits semantic and statistical approaches to extract relevant insights from each document; these data are then organized in a KG that allows for their interconnection. The methodology has been successfully tested on news articles related to crime events occurred in the city of Modena, in Italy. The promising results demonstrate how KG-based analysis can improve the management of information coming from online sources
SANICLAY-T: simple thermodynamic-based anisotropic plasticity model for clays
Full text linkIn this work the anisotropic model for clays SANICLAY proposed by Dafalias and Taiebat (2013) is reformulated within the framework of hyper-elastoplasticity. The model, called SANICLAY-T, is fully defined by two scalar potential functions, the free energy and the rate of dissipation. It is first presented in the triaxial space and then generalised in the multiaxial one. The model reproduces exactly the original one for the case of associate flow rule, while leads to a different outcome for non-associated flow. When compared to existing hyperplastic models accounting for rotational hardening, the proposed one proves to be more versatile, as characterised by less restrictive constraints on the hardening and asymptotic behaviour of the soil. The predictive capability of the model is illustrated with reference to experimental data on natural and reconstituted clays, highlighting its merits and limitations
Prefazione a Rollo F: Il DNA nello studio dei resti umani antichi, principi, metodi, applicazioni
No full textBone lesions from the ossuary of the Napoleonic battle of Marengo, northern Italy (14th June 1800).
No full textMarengo was the scenario of one of the most important battles of the Napoleonic age, where about 7,000 soldiers died, among whom the French General Desaix.
However, the exploration of the Marengo ossuary revealed only a small sample of the dead soldiers and was represented in general by the long bones of the limbs. In fact, if we exclude the children and the bones of sure archeological derivation, the remains of the soldiers, males between 20 and 30 years of age, who certainly died in the battle, are about 250.
Despite these limits, a number of traumatic lesions were diagnosed, which have been subdivided in chronic pathologies, prior to the battle, and acute pathologies, which took place during the battle.
The chronic pathologies include a case of ossification due to a muscle trauma, nine cases of periostitis and three cases of recovered fractures.
The ossification of an injury of the muscle took place along the linea aspera of the femur, connected with the insertion of the adductors and the pectineous, muscles which are particularly developed in horsemen. Three cases of periostitis, also observed along the linea aspera of the femur in connection with the insertion of the adductors, can also be ascribed to the heavy practice of horse-riding.
Six cases of tibial periostitis connected with the insertion of the inferior tibialis can be considered "marching" lesions. The presence of these lesions, caused by the frequent marching practice in infantry detachments, is not surprising.
The fractures, all well consolidated at the level of the medio-diaphysial tract, and for this reason referring to direct traumas, can be connected with the military profession or probably took place in previous combats.
The first case is a medio-diaphysial fracture of the right radius (also called “defense” or “Parry’s” fracture), well consolidated “in axis”, with no deformation or shortening of the forearm; the fracture was probably very well treated by a good military surgeon.
Interesting is the fracture of a right humerus, consolidated in angular deformity, with a 5 cm shortening of the bone.
Finally there is the fracture of a right tibia, very badly healed, with a severe shortening of the inferior limb of about 6 cm.
Very few – although significant – diagnoses of acute lesions have been made, certainly coinciding with a rapid death of the subject involved.
There are also two lesions caused by a cutting blade, and another one caused by a fire-arm.
A right humerus shows a thin cut, with sharp margins, 3.5 cm long, 2 mm wide, 3.5 cm deep, involving posteriorly the superior epiphysis. This almost perfect median cut has a vertical direction, involving the head, the anatomic and the surgical neck.
The characteristics are those of the point of a “briquet”, the typical dagger of the French infantry. The wound was certainly produced from behind, and top-downwards, involving the right humerus through the deltoid. From this direction, it is likely that the blow was directed against a run-away or a falling soldier.
Another lesion was caused by a cutting blade involving the left area of a frontal bone. The lesion consists in a triangular cut with superior apex, 11 mm long and a maximum of 3.2 mm wide, involving the frontal tuber in its medium tract; presumably, the wound was produced by the central part of a cutting blade, possibly a “briquet” in this case as well.
The lesion caused by a fire-arm involves the right half of the squama of a frontal bone. It consists in a circular breach, with clear-cut margins, extending towards the interior and showing a clear inward beveling; it shows a trunk-conic profile, with an external diameter of 21.5 mm and an internal diameter of 27 mm. The defect was certainly produced by a penetrating projectile, and the external diameter of 21.5 mm well corresponds to the 20 mm caliber of the so-called “biscaillens”, the iron balls of the grape-shot cannons.
It is evident that the exiguous number of lesions we have identified can only offer a glimpse of the traumatology of this important battle-field of the Napoleonic age. It is sufficient however to explain the scientific interest of the results obtained with this type of material.
Only an accurate exploration of eventual military common graves or of an entire war cemetery with intact burials could offer a more global and realistic traumatological picture
