Long short-term memory for indoor localization using WI-FI received signal strength and channel state information

Indoor location information is increasing in importance in contemporary communication services and applications. In this paper, we discuss the long short-term memory (LSTM) performance for indoor localization in non-line-of-sight (NLoS) conditions using the received signal strength (RSS) and channel state information (CSI) obtained from Wi-Fi signals. As such, we describe the CSI and RSS acquisition system that is used to build a rich dataset to experiment with classical machine learning and deep learning models. The distance range error matrix is combined with the confusion matrix to obtain the distance range error probability where we have demonstrated that the LSTM model exhibits a maximum range error of less than 5 m with 4% probability

Valorisation des produits laitiers typiques de Thessalie : diagnostic et stratégie locale

Publication du projet européen LACTIMED (ANIMA / CIHEAM-IAMM) avec l'Université de ThessalieLactimed a réalisé un diagnostic de la filière laitière de Thessalie (Grèce) afin d’aider les autorités locales et les structures d’appui à adopter une stratégie pour la valorisation des produits laitiers typiques de leur territoire. Ce rapport de diagnostic inclut un état des lieux de la filière, l’analyse des résultats d’enquêtes de terrain menées auprès des producteurs, l’identification de produits laitiers typiques avec leur cahier des charges de production et des informations sur le marché domestique

Arte, verdad y la verdad del arte como acción creadora

En el ámbito del desarrollo del devenir artístico, la acción creadora ha sido movilizada y potenciada siempre en función de unos criterios de regulación que han formulado y articulado semánticamente dicha acción: el concepto de verdad es en este sentido clave y signficado en la determinación creadora y estética

Are artificial insemination centres ready to replace egg yolk by low density lipoproteins (LDL) in extenders for bull semen cryopreservation? : recent results review

Poster Abstract P50International audienceEgg yolk is widely used by artificial insemination (AI) centers for bull semen cryopreservation. Laboratory studies revealed that yolk contains granules that inhibit the respiration of spermatozoa and reduce their motility. Also, they interfere with microscopic observations. Egg yolk could also be a source of microbial contaminations. Therefore, there have been many attempts to find out which components in the egg yolk provide the cell protection with the aim to replace egg yolk with it’s cryoprotective fraction in order to prepare a clearly chemically defined extender without inconveniences. Many investigations showed that LDL is the cryoprotective fraction of egg yolk. However, prior to extending its use to AI centres, in vivo fertility studies were required. Semen was taken from three bulls and frozen-thawed in two extenders: the LDL extender and a standard tris-egg-yolk extender. The quality of the semen was assessed prior to AI: motility was assessed using Hamilton Thorne ceros 12, and the integrity of the plasma membrane was assessed using the hypo-osmotic swelling test. For the first time, pregnancies were obtained following the AI of cows in the field (n = 193) with semen that had been frozen-thawed in the LDL extender. No significant difference (p > 0.05) was detected between the success rates of AI between the semen that had been frozen-thawed in the LDL extender (59.2%) and the control extender, Tris- egg yolk (65.3%). In conclusion, the in vivo fertility of semen that has been frozen-thawed in the LDL extender is maintained since gestations are obtained following AI; the LDL extender is suitable for use by AI centres

Dibutades o el arte de dibujar

El presente ensayo pretende explicar el dibujo como una actividad que se encuentra entre dos contrarios tomados de las teorías de Kandinsky: realismo puro y abstracción pura. Ambos se encuentran representados por dos famosas anécdotas clásicas escritas por Plinio en su Historia Natural que son el desafío entre Zeuxis y Parrasio, y el desembarco de Apeles en Rodas, en busca de Protógenes. Otra anécdota tomada también de los escritos de Plinio, la fábula de Dibutades -en donde se relata el nacimiento del dibujo en Corinto- será considerada como la solución a estos dos contrarios. En cualquier caso, esta solución no será tomada como síntesis o como cualquier tipo de justo medio, sino como paradoja, como paradoja creativa
