This dataset is related to the research article entitled "A system of automatic recognition of species of Brazilian flora based on textural characteristics of macroscopic images of wood", by Deivison Venicio Souza, Joielan Xipaia Santos, Helena Cristina Vieira, Tawani Lorena Naide, Silvana Nisgoski and Luiz Eduardo S Oliveira accepted in the journal Wood Science and Technology.
Wood samples were from the collection of the Wood Anatomy and Quality Laboratory (LANAQM) of Federal University of Paraná (UFPR), located in Curitiba, Paraná. The wood samples’ transversal surfaces were sanded with a 120 sandpaper and macroscopic images of 46 species were taken with a Zeiss Discovery V 12 stereomicroscope, with size of 2080 × 1540 pixels and 10× magnification. The captured images have a resolution of 150 dpi. A total of 1,901 macroscopic images were obtained.
Of the 46 species used in this study, 7 are on Brazil’s official list of endangered species. More specifically, the species Araucaria angustifolia and Ocotea porosa are classified in the category “Endangered”, Cedrela fissilis, Bertholletia excelsa, Mezilaurus itauba and Swietenia macrophylla are part of the “Vulnerable” group, and Euxylophora paraensis is considered “Critically Endangered”.

This dataset is composed of 58 apple tree images. They were taken during full bloom in an apple orchard located at National Institute of Agricultural Technology (INTA) Experimental Station, General Roca, Argentina (39° 1’ 34’’ S; 67° 44’ 24.6’’ W).The orchard was established in 2003 with ‘Red Chief’ cultivar apple trees grafted on MM111 rootstock .Trees were planted in a total area of 0.8 ha at a distance of 1.5m between trees by 4m between rows and were trained as espalier. A few days before full bloom, images were obtained from 32 trees, under two conditions: i) natural daylight between 10 am and 13 pm, ii) at night with the artificial flash light of the camera. A black curtain was unfolded behind the trees when images were obtained under daylight conditions in order to avoid interference from neighboring trees. All images were taken with an RGB digital camera (14.1 MP) at approximately 3.0 m from the tree in a 90° angle to the row. An object of known dimensions (a 15x15 cm square) was placed in each tree as a scale reference. Simultaneously, all the flowers on each tree were manually counted.
Images taken by using different proximal sensors can be used to estimate the number of flowers or fruits in trees. The accuracy of those methods have been studied and tested by many researchers during the past few years with encouraging results. Since manual counting method in fruit crops is a time-consuming labor and also lead to inaccurate results, image analysis could be used as an alternative procedure. The use of images could provide reliable and consistent data.
En se basant sur les résultats de recherches réalisés ces derniers années, il a été démontré que le Ratio de Concentration présente une influence sur la performance global des collecteurs solaires cylindro-parabolique. Notament ce paramètre influe sur l'entropie et l'efficience thermique. De ce fait, sa variation pourait également avoir des conséquences sur l'éfficience optique du concentrateur. C'est a juste titre qu'il a été entrepris cette étude qui vise a comparer l'éfficience optique de trois modèles de concentrateurs distingués par trois differentes ratio de concentration en les simulant numeriquement para la méthode MCRT atravers le logiciel SolTrace.
En effet, les trois valeurs du ratio de concentretion e les données de simulation ont été obtenus en optimisant les paramètres géométriques e optiques du concentrateur par le biais des équations mathématiques qui gouvernent son fonctionement. La simulation numérique a été fait en maintenant la distance du foyer constante a 1,75. Après la simulation numérique, les resultats obtenus sont présentés sous deux banques de données pour chaque modèle de collecteur : le flux de chaleur autour de du tube absorbeur e les points dínterssections des rayons solaires avec les éléments du concentrateur.
Histone deacetylases have been recognized as a potential target for epigenetic aberrance reversal in the various strategies for cancer therapy, with HDAC6 implicated in various forms of tumor growth and cancers. Diverse inhibitors of HDAC6 has been developed, however, there is still the challenge of iso-specificity and toxicity. In this study, we built a categorical random forest model on all HDAC6 inhibitors curated in the Chembl database (3,742). The model had an 85% balanced accuracy upon rigorous validations and was used to screen the SCUBIDOO database; 7785 hit compounds resulted and were docked into HDAC6 CD2 active-site. The top two compounds had a binding affinity of -78.56kcal/mol and -78.21kcal/mol respectively. The compounds were subjected to exhaustive docking protocols (Qm-polarized docking and Induced-Fit docking). Upon optimization of the compounds, the compounds showed improved binding affinity, putative specificity for HDAC6, and good ADMET properties. We have therefore developed an accurate and reliable model to screen for HDAC6 inhibitors and suggested a series of optimized structures showing high binding affinity and putative specificity for HDAC6.

Figure 1 (Fig1_Measurement_Setup) shows a hydraulic illustration of the investigated exhaust air heat pump (EHA-HP) and the position of the installed sensors.
Air temperature and humidity on all four sides of the unit (outdoor air, extract air coming from the building, supply air to the building and exhaust air leaving the house) and electrical power consumption of the unit (compressor and ventilators) were measured and logged.
The measurement period was 55 winter days with an interval of 1 second.
In addition, the dynamic pressure difference (as an indication of the air volume rate) on the exhaust side was logged during the measurement period. Finally, the air volume rates of the unit at different ventilation levels was measured using Constant injection tracer gas method. Figure 2 (Fig2_summary_Vol_rates) summarizes the measured air volume rates and ventilators’ powers usage in different levels.
The measurements were conducted in a KfW 55 efficient house with a living area of 235 m² near Stuttgart, Germany.
The EHA-HP was installed in an air based hybrid heating system as the central heating source of the building.
Figure 3 (Fig3_Applied_Sensors) gives an overview of the applied measurement methods and used sensors. Logging and conversion of signals were conducted using a modular I/O system; the fieldbus controller Ethernet 750-881 from WAGO Kontakttechnik.
