Abstract A growing number of studies seek to identify global priority areas for conservation and restoration. These studies often produce maps that highlight the benefits of concentrating such activity in the tropics. However, the potential equity implications of using these prioritization exercises to guide global policy are less often explored and articulated. We highlight those equity issues by examining a widely publicized restoration priority map as an illustrative case. This map is based on a prioritization analysis that sought to identify places where restoration of agricultural land might provide the greatest biodiversity and carbon sequestration benefits at the lowest cost. First, we calculate the proportion of agricultural land in countries around the world that the map classifies as a top 15% restoration priority. A regression analysis shows that this map prioritizes restoration in countries where displacing agriculture may be most detrimental to livelihoods: countries that are poorer, more populated, more economically unequal, less food secure, and that employ more people in agriculture. Second, we show through another regression analysis that a similar pattern appears sub-nationally within the tropics: 5 km × 5 km parcels of land in the tropics that are less economically developed or more populated are more likely to be top 15% restoration priorities. In other words, equity concerns persist at a subnational scale even after putting aside comparisons between the tropics and the Global North. Restorative activity may be beneficial or harmful to local livelihoods depending on its conceptualization, implementation, and management. Our findings underline a need for prioritization exercises to better attend to the risks of concentrating potentially negative livelihood impacts in vulnerable regions. We join other scholars calling for greater integration of social data into restoration science.

ABSTRACT Identifying and mapping especially sensitive environments in coastal areas is essential to protecting these environments from the effects of oil spills. Accordingly, “hot spot” habitats and resources in the Chesapeake Bay, one of the nation's major estuarine ecosystems, have been illuminated in a unique series of four seasonal maps. Incorporating these maps into contingency planning and spill response efforts not only speeds the identification of priority areas requiring protection from oil spills, but also enhances the effort itself.

Google Maps is becoming popular in digital maps because of its user friendly human computerinteraction and easy to use Application Programming Interface (API) as a plugin to onlineapplications. Vehicular Ad-hoc Network (VANET) is conceptualizing moving cars as nodes ina dynamic road network. VANETs help manage the traffic through communication messagesamong the vehicles. In huge traffic loads too many messages create network congestion andstarvation. The basic objective of this research is to augment conventional VANET by addingmessage prioritization methodology, i.e. messages for top priority vehicles will be transmittedprior to the ones with lower priority. To this end, an algorithm has been developed andimplemented in a web application that incorporates Google maps for getting and displayingvehicle information. The proposed algorithm has been evaluated using experiments forthroughput and congestion avoidance in the network.

Prioritized Planning (PP) is a fast and popular framework for solving Multi-Agent Path Finding, but its solution quality depends heavily on the predetermined priority ordering of the agents. Current PP algorithms use either greedy policies or random assignments to determine a total priority ordering, but none of them dominates the others in terms of the success rate and solution quality (measured by the sum-of-costs). We propose a machine-learning (ML) framework to learn a good priority ordering for PP. We develop two models, namely ML-T, which is trained on a total priority ordering, and ML-P, which is trained on a partial priority ordering. We propose to boost the effectiveness of PP by further applying stochastic ranking and random restarts. The results show that our ML-guided PP algorithms outperform the existing PP algorithms in success rate, runtime, and solution quality on small maps in most cases and are competitive with them on large maps despite the difficulty of collecting training data on these maps.

The criminal justice system in the United States was not created to treat mentally ill people. Despite this fact, the number of seriously mentally ill people in prisons and jails now exceeds the number in state psychiatric hospitals by tenfold.
At the same time, the epidemic of mass incarceration in the United States has become one of the most pressing economic and social problems our country has faced in the last three decades.
One novel approach to reducing prison populations and lowering costs to taxpayers has been justice reinvestment. However, for justice reinvestment to meet its ultimate goal of reducing incarceration rates, saving tax payer dollars, and creating safer communities, the JRI must begin to focus more attention and resources on how to better address the unique needs of the mentally ill in the criminal justice system.

The presence of priority and emerging flame retardants (FR) in the environment deserve attention since many of these substances are toxic and persistent. The aim of this thesis was to evaluate the occurrence and impact of priority and emerging flame retardants in the aquatic environment. To accomplish this main objective, the present thesis involved the development of multiresidue methods for the analysis of different FR families in water, sediment, dust and sewage sludge and the application of developed methods for FR monitoring in rivers (UK and Spain) and wastewater treatment plants (WWTPs). Firstly, a multiresidue method based on gas chromatography (GC) coupled to quadrupole mass spectrometry (MS) was developed to determine organophosphorus flame retardants (OPFRs), polybrominated diphenyl ethers (PBDEs), new brominated flame retardants (NBFRs), bromophenols, bromoanilines, bromoanisoles and bromotoluenes. A comparison of two ionization techniques (electron ionization - EI, and electron capture negative ionization - ECNI) and two acquisition modes (selected ion monitoring – SIM, and selected reaction monitoring - SRM) revealed that GC-ECNI-MS/SIM presented the highest sensitivity at expenses of identification capacity, while GC-EI-MS/MS was the most selective technique, permitting the identification of target compounds at the pg levels. This last method was proposed for the determination of FRs in environmental samples. An extraction method for 8 PBDEs, 9 NBFRs and 10 OPFRs in river water and wastewater was developed based on solid phase extraction using Oasis HLB cartridges. In addition, a passive sampling method for monitoring of OPFRs and NBFRs in surface water was developed using the ceramic dosimeter device with HLB as receiving phase. The passive sampler was efficient for the monitoring of target compounds in river water for a deployment time of about 3 weeks, as evidenced by comparison of results obtained by passive and grab sampling. Furthermore, the extraction of target compounds in sediment, sewage sludge and dust was developed using ultrasound-assisted extraction with ethyl acetate/cyclohexane (5:2, v/v), clean-up with florisil cartridges and analysis by GC-EI-MS/MS. The method proved to be efficient and robust for analysis of target compounds in the studied matrices, as evidenced by the results obtained using spiked samples, a certificated reference material and by participating in an interlaboratory study.
Monitoring studies were performed at the River Aire (Yorkshire, UK) and at three Spanish rivers (Nalón, Arga and Besòs). In all cases, samples were collected in several points alongthe rivers, fromthe sourceto the mouth, and afterWWTP outputs, in order to identify themost important sourcesof FRs. In addition, influents, effluentsand sludge samples from five Spanish WWTPs were analyzed forevaluatingthe impact of WWTPs as a source ofFRto receiving waters. Among all FR studied, OPFRswerethe most ubiquitouscontaminants in surface waters, andWWTPeffluents wereindicated as the main source ofthese compounds.BDE-209 was themost abundantPBDEcongenerand was detected in water inthe River Aire (UK),in sediments fromthe River Besòs (Catalonia)and in sewage sludge.Low frequency of detection wasobserved for NBFRs in the studied riversand WWTPs.The minor presence of NBFR in the aquaticenvironment pointsto the impression thateither thesecompounds havenotbeen used in Spain or the UK or eitherthatthey have not been used long enough or atsufficient amounts to pose an environmental problem.A toxicity testperformed with Daphniamagnarevealed that OPFRs toxicity (EC50) waswell correlated with their lipophilicity (log Kow), that these compoundspresent similar mode of actionand thattheir joint effects are additive.This mean that joint toxicity of OPFRs at lowconcentrations can produce toxic effects in theaquatic organisms,andsomixturesof these contaminantsmust be considered in risk assessmentstudies. Finally, theriskassessment performed for the studied rivers indicated no risk associated to observedOPFR levels in waters. However, apotential risk foraquatic organismswas estimatedfor the River Aire (UK) associated tothehigh concentrationsof BDE-209 in water.El objetivo de la presente tesis consistió en el desarrollo de métodos para el análisis multiresiduo de distintas familias de retardantes de llama en matrices ambientales, y su aplicación en estudios de vigilancia ambiental. Entre los diferentes métodos instrumentales desarrollados, el método basado en la cromatografía de gases acoplada a la espectrometría de masas en modo tándem (GC-EI-MS/MS) fue el más adecuado para el análisis de ocho éteres de polibromodifenilo (PBDEs), nueve nuevos retardantes de llama bromados (NBFRs) y diez retardantes de llama organofosforados (OPFRs) en las matrices ambientales propuestas en este estudio. Para el análisis de agua, se desarrolló un método basado en la extracción en fase sólida utilizando cartuchos HLB. Además, se desarrolló un método de muestreo pasivo para la determinación de cuatro OPFRs y dos NBFRs en agua de río utilizando un muestreador “ceramic dosimeter” y HLB como fase receptora. Para el análisis de sedimentos, lodos de depuradora y polvo, se desarrolló y validó un método utilizando la extracción líquido-sólido en un baño de ultrasonidos con acetato de etilo/ciclohexano (5:2, v/v), y purificación de los extractos con cartuchos florisil. El estudio de vigilancia ambiental incluyó la determinación de los compuestos objeto de estudio en 4 ríos de Inglaterra y España y cinco depuradoras en Catalunya. Se analizaron aguas y sedimentos de los ríos e influentes, efluentes y lodos de las depuradoras. Se observó que los OPFRs son los compuestos más ubicuos y más abundantes en todas las muestra ambientales, mientras el BDE-209 se detectó en los ríos y en los lodos de las depuradoras. Los demás PBDEs, y el DBDPE, HBB, PBEB, PBT, EHTBB, BTBPE y BEHTBP se detectaron con una menor frecuencia. Los estudios de toxicidad con Daphnia magna indicaron que mezclas de OPFRs poseen toxicidad aditiva. Se llevó a cabo la evaluación del riesgo para los distintos ríos estudiados y se observó que no hay un riesgo asociado con los niveles de los OPFRs presente en las aguas, pero se observó un riesgo asociado a la presencia del BDE-209 en las aguas del río Aire en Inglaterra.

A construção dos mapas Genéticos é importante para o melhoramento genético de plantas, pois são através desses mapas que pode se determinar em que pontos dos cromossomos as unidades hereditárias podem estar. Com o objetivo de verificar se o método Bayesiano incluindo a informação a priori pode ou não ser empregado nos estudos de construção de mapas Genéticos, estimativas Bayesianas e de máxima verossimilhança para a freqüência de recombinação foram obtidas, envolvendo espécies de polinização aberta. Para isso, foram considerados diferentes tipos de marcadores: marcadores completamente informativos e marcadores parcialmente informativos. Através de simulações de conjuntos de dados combinando dois marcadores de cada vez, as estimativas da freqüência de recombinação foram obtidas através de um algoritmo baseado na função de verossimilhança para os dois métodos de estimação usados. A caracterização das fases de ligação foi baseada na distribuição da probabilidade a posteriori dos arranjos de alelos alternativos em dados marcadores para dois cromossomos homólogos de cada genitor, condicional aos fenótipos observados dos marcadores. Os resultados obtidos permitem concluir que o método Bayesiano pode ser usado em estudos de ligação Genética com o uso da informação a priori. Quanto a estimação das fases de ligação, os dois métodos levam sempre à mesma conclusão.The construction of the Genetic maps are essential for the genetic improvement of plants, because through this maps that it can be determined in which spots within the chromosomes the hereditary unities could be. With the aim of checking whether the Bayesian method including the prior information can or not to be used in the studies of Genetic maps construction, Bayesians estimates and of maximum likelihood for the recombination frequency were obtained, outbreeding species. For that, diferent types of markers were considered containing fully informative markers and partially informative markers. Through simulations of groups of data combining two markers one at a time, the estimates of the recombination frequency were obtained through a general maximum-likelihood based algorithm for the two used estimate methods. The characterization of linkage phases was based in the posterior probable distribution of the assignment of alternative alleles at given markers to two homologous chromosomes of each parent, conditional on the observed phenotypes of the markers.The results obtained allows to conclude that the Bayesian method can be used in studies of Genetic linkage with the use of the priori information. As the estimate of the linkage phases, the two methods always get to the same conclusion.

En France, au contraire de pays comme les États-Unis, la pratique de l'évaluation économique a priori des actions collectives de lutte contre les inondations est largement déficiente. Ce constat est inquiétant dans une perspective d'allocation optimale de ressources nécessairement limitées. Quand elle existe, cette évaluation n'intègre pas les préférences des populations affectées. Ce manque est à contre-courant des préconisations de la convention d'Aarhus signée par la France. Dans cette thèse, l'apport envisageable de l'évaluation contingente est explorée. Deux enquêtes ont été réalisées, sur deux terrains aux caractéristiques contrastées : sur le bassin versant de l'Yzeron (zone péri-urbaine sur un petit bassin versant aux crues rapides et aux enjeux humains forts) et au Mans (zone urbaine à la confluence de la Sarthe et de l'Huisne aux crues lentes et aux enjeux humains faibles). Inscrite dans une perspective d'évaluation a priori de différents niveaux de protection collective, la réalisation de ces enquêtes a nécessité l'élaboration d'un outil de communication permettant une description, accessible aux non-experts, des effets des scénarios contingents sur le degré d'exposition d'une collectivité aux inondations. L'analyse des enquêtes permet un certain nombre d'analyses critiques quant aux choix méthodologiques employés (impact du choix des taxes locales comme support de paiement sur le taux de refus par exemple). Elle permet également de dégager un comportement des individus interprété comme une acceptabilité du risque d'inondation au-delà d'un certain niveau de protection. Confirmée, cette conclusion aurait un impact direct sur la nécessité de pratiquer enfin une évaluation économique a priori des actions collectives de lutte contre les inondations, intégrant de surcroît explicitement les préférences des populations affectées.

Aim: To examine the relationship between reported vigorous physical activity (VPA) and body mass index (BMI) in children (6–7 years) and adolescents (13–14 years). Methods: In the International Study of Asthma and Allergies in Childhood Phase Three, 75 895 children's parents and 199 502 adolescents answered questions relating to VPA, height and weight. The association between VPA and BMI was analysed using general linear models, adjusting for country gross national index. Results: Compared to children who undertook no VPA, those in the infrequent group (once or twice per week) and those in the frequent group (three or more times per week) had mean (95% CI) BMI values 0.07 kg/m 2 (0.03–0.11) and 0.09 kg/m 2 (0.03–0.15) greater, respectively (p = 0.001). Compared to adolescents reporting no VPA, those in the infrequent group had a BMI 0.19 kg/m 2 (0.15–0.23) greater while those in the frequent group had a BMI 0.01 kg/m 2 (−0.03–0.05) greater (p < 0.0001). Conclusion: Reported VPA is not associated with lower BMI among children and adolescents. Investigation of VPA and BMI may be best undertaken in conjunction with other variables in the energy expenditure equation. A focus on VPA alone may be an inefficient way to manage BMI.Revisión por pares

Η ανάγκη αντιμετώπισης του προβλήματος της ρύπανσης των επιφανειακών και υπόγειων υδάτων έχει οδηγήσει στην ανάπτυξη νέων και αποτελεσματικών μεθόδων για την απομάκρυνση έμμονων και μη βιοαποικοδομήσιμων ενώσεων από το νερό και τα υγρά απόβλητα. Η παρούσα διατριβή πραγματεύτηκε τη συστηματική μελέτη της διάσπασης ρύπων προτεραιότητας και αναδυόμενων ρύπων που ανήκουν σε διαφορετικές χημικές κατηγορίες (DEET, metribuzin, 2-ισοπρόπυλο-3-μεθόξυ πυραζίνη, η πενταχλωροφαινόλη, βενζοϊκό οξύ, Cr(VI) και φαινολικές ενώσεις) με τη μέθοδο της ετερογενούς φωτοκατάλυσης και τη χρήση εμπορικά διαθέσιμων δραστικών μορφών TiO2 και τροποποιημένων σωματιδίων ΤiΟ2 με αμέταλλα που παρουσιάζουν φωτοκαταλυτική δραστικότητα στο ορατό φάσμα της ακτινοβολίας. Για το σύνολο των ενώσεων που μελετήθηκαν, η έρευνα επικεντρώθηκε: i) στη μελέτη της κινητικής της αποδόμησης και της ολικής ανοργανοποίησης τους με τη μέθοδο της ετερογενούς φωτοκατάλυσης, ii) στη μελέτη της επίδρασης λειτουργικών παραμέτρων στην απόδοση της φωτοκαταλυτικής απομάκρυνσης των ρύπων και στην εύρεση των βέλτιστων συνθηκών με την εφαρμογή των δύο ευρέως χρησιμοποιούμενων χημειομετρικών μεθόδων, της μεθοδολογίας επιφάνειας απόκρισης (RSM) και των τεχνητών νευρωνικών δικτύων (ANNs), iii) στην ανίχνευση και ταυτοποίηση ενδιάμεσων προϊόντων διάσπασης των οργανικών ρύπων με φασματομετρικές τεχνικές όπως υγρή χρωματογραφία-φασματομετρία μαζών υψηλής διακριτικής ικανότητας και ακρίβειας μάζας με αναλυτή τροχιακής παγίδας (Orbitrap) και αέρια χρωματογραφία–φασματομετρία μάζας με την τεχνική ιοντισμού με πρόσκρουση ηλεκτρονίων (Εlectron Impact, EI) και φασματοσκοπία ηλεκτρονικού παραμαγνητικού συντονισμού, iv) στη συνεισφορά των δραστικών ειδών οξυγόνου, οπών και ηλεκτρονίων στη φωτοκαταλυτική αποικοδόμηση των ρύπων, v) στη μελέτη του ρόλου των φυσικών συστατικών (χουμικά και φουλβικά οξέα) διαφόρων υδατικών συστημάτων καθώς και στην εκτίμηση της επίδρασης του υδατικού μέσου στην κινητική της διεργασίας, vi) στην εκτίμηση της τοξικότητας πριν και κατά τη διάρκεια της φωτοκαταλυτικής επεξεργασίας.
Με την εφαρμογή της ετερογενούς φωτοκατάλυσης επετεύχθη πλήρης απομάκρυνση όλων των ρύπων-μοντέλων που μελετήθηκαν και υψηλός βαθμός ανοργανοποίησης των διαλυμάτων τους. H φωτοκαταλυτική διάσπαση λαμβάνει χώρα σε ποσοστό μεγαλύτερο του 90% σε χρόνους που κυμαίνονται από 20-180 λεπτά ανάλογα με το μελετώμενο ρύπο. Ένας μεγάλος αριθμός κύριων προϊόντων διάσπασης και τουλάχιστον ένα ισομερές για τα περισσότερα από αυτά, ταυτοποιήθηκε κατά τη φωτοκαταλυτική διάσπαση της PCP, του DEET, του ΜΕΤ και της ΙPMP με τη χρήση προηγμένων τεχνικών φασματομετρίας μάζας. Με βάση τα προϊόντα που ταυτοποιήθηκαν, προτάθηκαν οι μηχανισμοί της φωτοκαταλυτικής διάσπασης των μελετώμενων ρύπων που περιλαμβάνουν κυρίως αντιδράσεις υδροξυλίωσης, οξείδωσης και απαλκυλίωσης. Η οξείδωση μέσω ριζών υδροξυλίου (HO•)βρέθηκε να αποτελεί το κύριο οξειδωτικό είδος σε όλα τα μελετώμενα συστήματα. Η δοκιμή τοξικότητας που πραγματοποιήθηκε, πριν και κατά τη διάρκεια της φωτοκαταλυτικής επεξεργασίας των οργανικών ρύπων έδειξε ότι η μέθοδος της ετερογενούς φωτοκατάλυσης οδηγεί σε πλήρη αποτοξικοποίηση των διαλυμάτων.
Σύμφωνα με τα αποτελέσματα της φωτοκαταλυτικής οξείδωσης των οργανικών ρύπων-μοντέλων και της φωτοκαταλυτικής αναγωγής του Cr(VI) που μελετήθηκαν στην παρούσα διατριβή, η μέθοδος της ετερογενούς φωτοκατάλυσης μπορεί να αποτελέσει μια αποδοτική εναλλακτική πρόταση αντιρρύπανσης έναντι των κλασσικών μεθόδων. Η ουσιαστική λύση σε προβλήματα ρύπανσης αποφεύγοντας τη μεταφορά των ρύπων από τη μία φάση στην άλλη, η δυνατότητα χρήσης και αξιοποίησης ήπιων μορφών ενέργειας όπως η ηλιακή ακτινοβολία και η σύζευξη της μεθόδου με άλλες βιολογικές ή/και φυσικοχημικές μεθόδους επεξεργασίας αποδεικνύουν τις μεγάλες προοπτικές που παρουσιάζει.In order to avoid deterioration of water resources, considerable efforts have been devoted to develop suitable purification methods that can easily remove recalcitrant (persistent) and non-biodegradable contaminants from water and wastewater. In the present thesis the photocatalytic removal of selected priority pollutants and emerging contaminants belonging in different chemical categories has been investigated in detail. DEET, metribuzin, 2 isopropyl-3-methoxy pyrazine, pentachlorophenol (PCP), benzoic acid (BA), Cr(VI) and phenolic compounds were selected as target compounds. The commercial form of TiO2 (Degussa P25) and NF-codoped TiO2, a material with improved photo efficiency and visible light response were used as photocatalysts. The main objectives of this thesis were: i) to evaluate the kinetics of selected pollutants disappearance and mineralization, ii) to investigate the effect of significant parameters on the total process efficiency as well as to optimize the photocatalytic procedure by means of chemometric optimization tools such as central composite design, response surface methodology and artificial neural networks, iii) to identify the transformation products formed during the photocatalytic treatment by using powerful analytical techniques such as high resolution accurate mass LC-MS, GC–MS and EPR spectroscopy, iv) to assess the role of the reactive species in the reaction mechanism using different scavengers, v) to assess the macroscopic effects of DOM (HA, FA) and water matrix on the photocatalytic degradation and vi) to evaluate the toxicity along the photocatalytic process. By the application of heterogeneous photocatalysis almost compete removal of the selected model contaminants and high percentages of mineralization were achieved. Photocatalytic removal (> 90%) was succeeded after 20-180 min of irradiation time, depending on the studied pollutant. Numerous different structures of transformation products (TPs), with at least one isomer for the majority of them, were identified with high resolution accurate mass liquid chromatography (HR-LC–MS) and gas chromatography mass spectrometry (GC–MS). Based on by-product identification using HR-LC-MS and GC–MS techniques possible degradation pathways were proposed. The pathways mainly include hydroxylation, oxidation and dealkylation reactions. Hydroxyl radicals (HO•) were determined to be the predominant reactive species during photocatalysis in all the studied systems. Toxicity assessment revealed the efficiency of the photocatalytic treatment to achieve almost complete detoxification of the solution. According to the results obtained for the photocatlytic oxidation of the studied organic pollutants-models and photocatalytic reduction of Cr(VI), heterogeneous photocatalyis was shown to be a great potential as a sustainable treatment technology. Ιts inherent destructive nature, not involving mass transfer, the potential use of solar radiation as well as the combination of heterogeneous photocatalysis with biological and/or physicochemical methods make this method particularly attractive for environmental decontamination and detoxification.

AbstractThis study aims to examine the importance and performance analysis using a diagonal regression approach. Scale measurement used semantic differential. The diagonal of the regression coefficient was used to map the coordinates of the balance of the importance and performance analysis assessments with an estimation of the data spread of the standard error of estimation at an error rate of 5%. The results of the study indicate that there are 5 strategic areas of IPA: high priority areas to be improved, areas of a balance of performance and importance (ISO-IPA), low priority, keep up the good performance, and possible areas of waste of resources indicator.

AbstractSwitzerland is recognised as an immigration country. As in other European countries, awareness of the socio-economic costs of the non-integration of immigrants has led Swiss policy-makers to promote integration both as an individual duty (conditional on the requirements and individual responsibilities of a foreign person), as well as a policy priority for stakeholders at federal, cantonal, and communal levels. This pragmatic, yet in some cases restrictive, approach to integration has evolved gradually over time and has been strengthened by the divisive debates around foreigners that surrounded the 2014 initiative against mass immigration. In this context, we seek to provide a timely analysis of the evolving legal and policy framework that regulates the integration of migrants, refugees and asylum-seekers (MRAs) into the Swiss labour market and society. While we shed light on the development and changes pertaining to the relevant legislative and institutional framework, we also highlight key aspects that play an obstructing role to immigrants’ integration. Ultimately, we contend that not only certain legislative and administrative aspects, but also direct democratic instruments have provided important disabling barriers to migrants’ integration as they have not effectively managed to challenge ‘Fortress’ actualities and exclusionary trajectories of boundary construction.

The COVID-19 pandemic has challenged health systems worldwide by decreasing their reserves and effectiveness. In this changing landscape, the urge for reallocation of financial and human resources represents a top priority. In screening, effectiveness and efficiency are most relevant. In the quest against cervical cancer, numerous molecular ancillary techniques detecting HPV DNA or mRNA or other related biomarkers complement morphological assessment by the Papanicolaou test. However, no technique is perfect as sensitivity increases at the cost of specificity. Various approaches try to resolve this issue by incorporating several examination results, such as artificial intelligence are proposed. In this study, 1,258 cases with a complete result dataset for cytology, HPV DNA, HPV mRNA, and p16 were used to evaluate the performance of a self-organizing map (SOM), an unsupervised artificial neural network. The results of the SOM application were encouraging since it is capable of producing maps discriminating the necessary tests and has improved performance.

On small production lots on which medicinal plants are grown, irrigation systems of a smaller capacity (“drip, drip” and “sprinkling” systems) are mainly used. The water for irrigation should be in keeping with the national and the potential European quality standards, and should be as “free” as possible of potential pollutants, such as feces, heavy metals, pesticides, and toxicologically hazardous matters. Therefore, in this chapter, several priority MAPs are selected according to their importance for this sector, and their needs are analyzed in drought and irrigation conditions. In this group of plants, the authors included the following: marshmallow (Althaea officinalis L.), peppermint (Mentha piperita L.), valerian (Valeriana officinalis L.), lovage (Levisticum officinale Koch), lemon balm (Melissa officinalis L.), ribwort plantain (Plantago lanceolata L.), marigold (Calendula officinalis L.), and basil (Ocimum basilicum L.).

The aim of the study is to observe the dynamics of soil movement and deformation of the complex of buildings and structures in the Pidhoretskyi monastery on the basis of geodetic measurements in complex engineering and geological conditions in the protected area, as well as permanent monitoring of vertical displacements for analysis and further recommendations for concerning safe operation of engineering constructions. Due to significant landslides on the slopes of the terrace, the buildings and structures of the Pidhoretskyi monastery are in a state of emergency. To save the architectural monument of the 18th century, which is located on the territory of Plisnetskyi reserve, a reference geodetic planned-height network (proving ground) has been created, which allows to determine the magnitude and direction of soil landslides; to determine the deformation of buildings and structures; to determine the amount of subsidence of structures as well as monitoring these processes. The support network consists of 2 planned-height (source) soil geodetic points for control of six stationary observation stations, 4 of which are located on one top of the mountain slope, and 2 are on the other. The height basis is created by leveling of the II class. Planned-height network consists of eight lines: some are designed and laid parallel to the church buildings, others are directed towards the ravines to determine the dynamics of their movement. A total of 87 reinforcing marks for linear - angular observations are laid. To observe the deformations of buildings and structures, 35 external wall signs (benchmarks) were laid in the foundations of the buildings, 20 were laid in the retaining wall and 22 internal signs (dowels) were laid in the stone floor of the church. The total number of all wall signs are 77. We proposed the manufacture of polymer poles on the ground from the polymer pipes, with which we fixed all points of the planned height network. The convenience of their use is due to the fact that they meet the requirements of the instructions and they can be used in the territories of cultural heritage sites of national importance, without violating the Law of Ukraine. Centers can be made from improvised materials quickly and conveniently; their cost is quite low; ease and forced centering of devices and reflectors above the signs eliminates centering errors. Research methods. Geometric leveling of the second class with Ni-002 level and observation of displacements in the targets was performed at the proving ground. Research results. For the first time on the territory of Pidhoretskyi monastery a stationary geodetic proving ground was created for permanent observations of soil movements, deformations of buildings and structures. The points of the proving ground are laid down by the proposed types of centers. On the basis of geodetic observations, uneven and uniform subsidence of the marks of the studied buildings and structures, displacement of points of alignment were determined; maps of vertical movements of the earth's surface of the territory of the Pidhoretskyi monastery were created.

Though a clinical pathway is one of the tools used to guide evidence-based healthcare, promoting the practice of evidence-based decisions on healthcare services is incredibly challenging in low resource settings (LRS). This paper proposed a novel approach for designing an automated and dynamic generation of clinical pathways (CPs) in LRS through a hybrid (knowledge-based and data-driven based) algorithm that works with limited clinical input and can be updated whenever new information is available. Our proposed approach dynamically maps and validate the knowledge-based clinical pathways with the local context and historical evidence to deliver a multi-criteria decision analysis (concordance table) for adjusting or readjusting the order of knowledge-based CPs decision priority. Our finding shows that the developed approach successfully delivered probabilistic-based CPs and found a promising result with Jimma Health Center “pregnancy, childbearing, and family planning” dataset.

The IBSEN model of Imagination in Brain Systems for Episodes and Navigation explores how the architect’s experience is brought to bear in the design of architecture by building on the VISIONS model of understanding a visual scene and the TAM-WGM model of navigation. IBSEN develops the idea that a building provides both views from various viewpoints and places where particular experiences can be felt, and actions can be performed. For this, the design must support a variety of scripts for both practical and contemplative action and the cognitive maps that relate places for them. Nodes from different maps may be combined as scripts are harmonized with respect to a specific embedding of places in three-dimensional space. The chapter examines the role of the hippocampus in episodic memory and imagination, and observes that memory and imagination, episodic or not, are construction processes. During design, long-term working memory links internal and external memory systems, providing priority access to (but not only to) memory fragments that have proved relevant to the current design process. The designer in some sense “inverts” imagined experiences and behaviors of users of the forthcoming building. As the book ends, the author notes that we are only at the beginning of new collaborative studies that take cog/neuroscience out of the lab and into the building and the street.

Satisfying human needs means to respond directly to human choice / human commands at the time of purchase, in real time operation, for maintenance / tech mods over the life history of the vehicle, and for refreshment in the future hybrid electric vehicles (HEV) equipped with four-independent in-wheel motors (IWM). This leads to maximizing human choice. To meet human choice means not only to keep the human fully informed on a series of choices, but also to maximize their self-awareness. Meeting human choice requires visual performance maps. Based on the future HEV with an open (modular) architecture, visual performance maps help customers make right choices what they want, so that a vehicle can be tailored to a particular customer priority such as cost and drivability for an aggressive driver. This paper demonstrates how different types of an IWM are matched to different types of customers. The decision framework developed in this paper is based on detailed human needs structured by performance maps to visually guide the customer in terms of purchase / operation / maintenance / refreshment decisions. Part I is focused on purchase criteria, while Part II discusses operation / maintenance / refreshment criteria.

Following the 2000 European Landscape Convention, a new act strengthening landscape protection instruments has been in force since 2015. It sets forth legal aspects of landscape shaping (Dziennik Ustaw 2015, poz. 774) and introduces landscape audits at the province level. A landscape audit consists in identification and characterization of selected landscapes, assessment of their value, selection of so-called priority landscapes and identification of threats for preservation of their value. An audit complies with GIS standards. Analyses use source materials, i.e. digital maps of physical-geographical mesoregions, current topographic maps of digital resources of cartographic databases, latest orthophotomaps and DTMs, maps of potential vegetation, geobotanic regionalization, historic-cultural regionalization and natural landscape types, documentation of historical and cultural values and related complementary resources. A special new methodology (Solon et al. 2014), developed for auditing, was tested in 2015 in an urban area (Myga-Piatek et al. 2015). Landscapes are characterized by determining their analytic (natural and cultural) and synthetic features, with particular focus on the stage of delimitation and identification of landscape units in urban areas. Czestochowa was selected as a case study due to its large natural (karst landscapes of the Czestochowa Upland, numerous forests, nature reserves) and cultural (Saint Mary’s Sanctuary, unique urban architecture) potential. Czestochowa is also a city of former iron ore and mineral resources exploitation, still active industry, dynamic urban sprawl within former farming areas, and dynamically growing tourism. Landscape delimitation and identification distinguished 75 landscape units basing on uniform landscape background (uniform cover and use of the land). Landscape assessment used a new assessment method for anthropogenic transformation of landscape – the indicator describing the correlation between the mean shape index (MSI) and the Shannon diversity index (SHDI) (Pukowiec-Kurda, Sobala 2016). Particular threats and planning suggestions, useful in development of urban areas, were presented for selected priority landscapes.

Floods are one of the deadliest natural disasters in the world. According to the World Meteorological Organization (WMO), this is a consequence of the increasing frequency of heavy precipitation, changes in upstream land use, and a continuously increasing concentration of population and assets in flood-prone areas [1]. For this reason, flood prevention, and protection are a growing priority these days. Flood hazard mapping is a state-of-the-art tool for decision-makers and stakeholders when it comes to flood protection and Flood Risk Management Plans. The visualization of the various parameters (range, depths, velocities, etc.) of a flood event gives a clear vision for implementing measures that help to protect and restore the natural functions of rivers and floodplains. This article presents the different types of flood hazard maps - with either a single parameter or a combination of several parameters (range, depths, velocities, and combination of flow velocity and flow depth. For this purpose, results obtained from 2D modeling with the software product HEC-RAS were used. The digital terrain model used was provided by Drone and has a resolution of 0.05 cm. Land cover information from CLC 2018 was used to determine the Manning coefficients. According to Art. 146e. of the Water Act (New, SG No. 61/2010) [2], several scenarios should be considered for Bulgaria: low-probability floods, medium-probability floods, and high-probability floods. As a result, a number of maps with different probabilities of flood occurrence and different flood parameters were obtained. These maps were used to analyze and assess potential damage in the different flood scenarios and parameters.

With the ongoing stagnation of the progress towards higher efficiency gas turbines, alternative approaches in combustion receive more attention than ever before. Besides, increasing efficiency and reducing emissions at the same time has become a first priority of the industry in the last few decades. Constant volume combustion is considered a technology capable of achieving a significant increase in thermal efficiency when applied in gas turbines. In this work, models of gas turbine cycles with two different combustion methods, being a shockless explosion combustion and an isobaric homogeneous combustion, will be simulated and compared. A code based on the one dimensional Euler equations is utilized to calculate the exhaust gas outlet parameters of the shockless explosion combustion chamber, while taking into account all the gas dynamic phenomena in it. The efficiency of the turbine is computed by steady state operational maps. The simulations provide numerous detailed results with a focus on the dependency of the SEC cycle’s thermal efficiency to the compressor pressure ratio and the turbine inlet temperature. Evaluating the kinetic energy in the total enthalpy of the turbine inlet flow is also an essential investigation.

Ontario’s initial mass COVID-19 vaccination strategy in place until April 8, 2021 was based on per-capita regional allocation of vaccines with subsequent distribution – in order of relative priority – by age, chronic health conditions and high-risk congregate care settings, COVID-19 hotspots, and essential worker status. Early analysis of Ontario’s COVID-19 vaccine rollout reveals inequities in vaccine coverage across the province, with residents of higher risk neighbourhoods being least likely get vaccinated. Accelerating the vaccination of COVID-19 hotspots and essential workers will prevent considerably more SARS-CoV-2 infections and COVID-19 hospitalizations, ICU admissions and deaths as compared with Ontario’s initial mass vaccination strategy (Figure 1).

As Ontario expands access to the COVID-19 vaccine beyond the Phase 1 priority populations, strategic planning and execution of mass vaccine rollout will have a significant impact on the health and safety of Ontario’s 14.5 million residents. There are six key elements of Israel’s successful COVID-19 vaccine campaign that can be readily applied to Ontario to expedite and expand the province’s vaccine rollout strategy: a simple vaccine prioritization process; modification to the transport, storage, and distribution of the vaccines; effective communication to promote vaccine confidence; decentralization of vaccination sites; centralized organization through Health Maintenance Organizations (HMOs) using a fully integrated information technology (IT) system in a universal health care system; and the engagement of community-based personnel, infrastructure, and resources.

Повний текст джерелаАнотація:
The report provides a review of how risk is conceived of, modelled, and mapped in studies of infectious water, sanitation, and hygiene (WASH) related diseases. It focuses on spatial epidemiology of cholera, malaria and dengue to offer recommendations for the field of WASH-related disease risk mapping. The report notes a lack of consensus on the definition of disease risk in the literature, which limits the interpretability of the resulting analyses and could affect the quality of the design and direction of public health interventions. In addition, existing risk frameworks that consider disease incidence separately from community vulnerability have conceptual overlap in their components and conflate the probability and severity of disease risk into a single component. The report identifies four methods used to develop risk maps, i) observational, ii) index-based, iii) associative modelling and iv) mechanistic modelling. Observational methods are limited by a lack of historical data sets and their assumption that historical outcomes are representative of current and future risks. The more general index-based methods offer a highly flexible approach based on observed and modelled risks and can be used for partially qualitative or difficult-to-measure indicators, such as socioeconomic vulnerability. For multidimensional risk measures, indices representing different dimensions can be aggregated to form a composite index or be considered jointly without aggregation. The latter approach can distinguish between different types of disease risk such as outbreaks of high frequency/low intensity and low frequency/high intensity. Associative models, including machine learning and artificial intelligence (AI), are commonly used to measure current risk, future risk (short-term for early warning systems) or risk in areas with low data availability, but concerns about bias, privacy, trust, and accountability in algorithms can limit their application. In addition, they typically do not account for gender and demographic variables that allow risk analyses for different vulnerable groups. As an alternative, mechanistic models can be used for similar purposes as well as to create spatial measures of disease transmission efficiency or to model risk outcomes from hypothetical scenarios. Mechanistic models, however, are limited by their inability to capture locally specific transmission dynamics. The report recommends that future WASH-related disease risk mapping research: - Conceptualise risk as a function of the probability and severity of a disease risk event. Probability and severity can be disaggregated into sub-components. For outbreak-prone diseases, probability can be represented by a likelihood component while severity can be disaggregated into transmission and sensitivity sub-components, where sensitivity represents factors affecting health and socioeconomic outcomes of infection. -Employ jointly considered unaggregated indices to map multidimensional risk. Individual indices representing multiple dimensions of risk should be developed using a range of methods to take advantage of their relative strengths. -Develop and apply collaborative approaches with public health officials, development organizations and relevant stakeholders to identify appropriate interventions and priority levels for different types of risk, while ensuring the needs and values of users are met in an ethical and socially responsible manner. -Enhance identification of vulnerable populations by further disaggregating risk estimates and accounting for demographic and behavioural variables and using novel data sources such as big data and citizen science. This review is the first to focus solely on WASH-related disease risk mapping and modelling. The recommendations can be used as a guide for developing spatial epidemiology models in tandem with public health officials and to help detect and develop tailored responses to WASH-related disease outbreaks that meet the needs of vulnerable populations. The report’s main target audience is modellers, public health authorities and partners responsible for co-designing and implementing multi-sectoral health interventions, with a particular emphasis on facilitating the integration of health and WASH services delivery contributing to Sustainable Development Goals (SDG) 3 (good health and well-being) and 6 (clean water and sanitation).

The long-term goals of our research are to understand the regulation of sclerotial development and pathogenicity in S. sclerotiorum. The focus in this project is on the elucidation of the signaling events and environmental cues involved in the regulation of these processes, utilizing and continuously developing tools our research groups have established and/or adapted for analysis of S. sclerotiorum. Our stated specific objectives were to: 1. Follow activities and function of S. sclerotiorumPKA. 2. Identify and functionally evaluate effectors of the S. sclerotiorumERK-likeMAPK signaling pathway. 3. Perform structural and functional analysis of genes whose expression is altered under conditions affecting either PKA and/or MAPK. As can be seen below, we have not only met most of the listed goals, but have also expanded our research. We have been working both together and in parallel in order to advance our goals. We have jointly shown how an ERK-likeMAPK is required sclerotia formation. We have analyzed, in parallel, the involvement of PKA in sclerotiogenesis and, interestingly, have reached some overlapping results but each group has provided a slightly different interpretation to the picture obtained. It will be interesting to see how this aspect of the analysis progresses, as we jointly tackle the yet unresloved issues. We have also made progress on the analysis of ser/thr phosphatases (specifically – calcineurin, which has been reported to interact with PKA) and PP2A in S. sclerotiorum as well as the S. sclerotiorum rasgene, which we have cloned and shown induces SMK1, the ERK-like kinase responsible for sclerotia formation. In addition to the time and efforts invested towards reaching the specific goals mentioned, both PIs are actively involved in a major international effort to sequence and annotate the entire S. sclerotiorum genome. Though time consuming (and perhaps requiring divergence of some time and resources from the original workplan), we have given this topic a very high priority to this effort as the long term implications of the success of this venture are enormous.

La Politique bioalimentaire du gouvernement du Québec place les attentes des consommateurs et leur santé au cœur des priorités pour les prochaines années. Offrir des produits répondants aux besoins des consommateurs figure parmi les principales orientations définies pour atteindre les ambitions et les cibles de cette politique. Dans ce contexte, le Baromètre de la confiance des consommateurs québécois à l’égard des aliments du CIRANO est un outil important et très utile à la prise de décisions pour le gouvernement, mais aussi pour l’ensemble des parties prenantes du secteur bioalimentaire. Réalisé sur une base régulière, le Baromètre permet de bien cerner les tendances et de tenir compte de l’évolution du contexte dans lequel les Québécoises et Québécois font des choix en matière d’alimentation. Ce rapport constitue la première édition du Baromètre et fournit des informations riches, opportunes et inédites sur un ensemble d’enjeux reliés au niveau de confiance des consommateurs à l’égard des aliments. Cette première édition est fondée sur une enquête administrée du 9 au 15 mai 2019 auprès d’un échantillon représentatif de 1017 personnes et est surtout utile afin d’avoir une photo de la situation au Québec en 2019, ce qui servira de point de repère pour les autres éditions.

La Politique bioalimentaire du gouvernement du Québec place les attentes des consommateurs et leur santé au cœur des priorités pour les prochaines années. Offrir des produits répondants aux besoins des consommateurs figure parmi les principales orientations définies pour atteindre les ambitions et les cibles de cette politique. Dans ce contexte, le Baromètre de la confiance des consommateurs québécois à l’égard des aliments du CIRANO est un outil important et très utile à la prise de décisions pour les différentes directions du ministère de l’Agriculture, des Pêcheries et de l’Alimentation du Québec (MAPAQ), mais aussi pour l’ensemble des parties prenantes du secteur bioalimentaire. Réalisé sur une base régulière, le Baromètre permet de bien cerner les tendances et de tenir compte de l’évolution du contexte dans lequel les Québécoises et Québécois font des choix en matière d’alimentation. Comme c’était le cas de la première édition en 2019, le Baromètre de 2021 fournit des informations riches, opportunes et inédites sur un ensemble d’enjeux reliés au niveau de confiance des consommateurs à l’égard des aliments. Il permet aussi d’identifier des actions à privilégier pour le gouvernement, incluant des leviers pour augmenter la consommation d’aliments biologiques ou d’aliments du Québec, s’attaquer au gaspillage alimentaire ou encore encourager les pratiques d’affaires responsables comme le bienêtre animal ou le respect de l’environnement. Cette deuxième édition du Baromètre est fondée sur une enquête administrée du 8 au 11 février 2021 auprès d’un échantillon représentatif de 1005 personnes. Le rapport présente des statistiques descriptives très détaillées, mais aussi les résultats d’analyses multivariées et tests statistiques afin de déterminer si les résultats varient significativement en fonction de certaines caractéristiques sociodémographiques des personnes interrogées comme le sexe, l’âge, la région de résidence, le revenu. Les analyses multivariées permettent aussi de déterminer si certains comportements, contextes, aptitudes ou attitudes ont un impact sur diverses variables d’intérêt, toutes choses égales par ailleurs.

The goal of the one-year feasibility study was to identify specific cytotoxic T-lymphocyte (CTL) epitopes to Neosporacaninum in the natural bovine host in order to make progress toward developing an effective peptide-based vaccine against bovine neosporosis. We tested the hypothesis that: N. caninum SRS2 peptides contain immunogenicCTLepitope clusters cross-presented by multiple bovine MHC-I and MHC-IIhaplotypes. The specific objectives were: (1) Map bovine CTLepitopes of N. caninum NcSRS-2 and identify consensus MHC-I and class-II binding motifs; and (2) Determine if subunit immunization with peptides containing N. caninum-specificCTLepitopes cross-reactive to multiple bovine MHChaplotypes induces a CTL response in cattle with disparate MHChaplotypes. Neosporosis is a major cause of infectious abortion and congenital disease in cattle, persisting in cattle herds via vertical transmission.5 N. caninum abortions are reported in Israel; a serological survey of 52 Israeli dairy herds with reported abortions indicated a 31% infection rate in cows and 16% infection rate in aborted fetuses.9,14 Broad economic loss due to bovine neosporosis is estimated at $35,000,000 per year in California, USA, and $100,000,000 (Australian) per year in Australia and New Zealand.13 Per herd losses in a Canadian herd of 50 cattle are estimated more conservatively at $2,305 (Canadian) annually.4 Up to date practical measures to reduce losses from neosporosis in cattle have not been achieved. There is no chemotherapy available and, although progress has been made toward understanding immunity to Neospora infections, no efficacious vaccine is available to limit outbreaks or prevent abortions. Vaccine development to prevent N. caninum abortion and congenital infection remains a high research priority. To this end, our research group has over the past decade: 1) Identified the importance of T-lymphocyte-mediated immunity, particularly IFN-γ responses, as necessary for immune protection to congenital neosporosis in mice,1,2,10,11 and 2) Identified MHC class II restricted CD4+ CTL in Neosporainfected Holstein cattle,16 and 3) Identified NcSRS2 as a highly conserved surface protein associated with immunity to Neospora infections in mice and cattle.7,8,15 In this BARD-funded 12 month feasibility study, we continued our study of Neospora immunity in cattle and successfully completed T-lymphocyte epitope mapping of NcSRS2 surface protein with peptides and bovine immune cells,15 fulfilling objective 1. We also documented the importance of immune responses NcSRS2 by showing that immunization with native NcSRS2 reduces congenital Neospora transmission in mice,7 and that antibodies to NcSRS2 specifically inhibition invasion of placental trophoblasts.8 Most importantly we showed that T-lymphocyte responses similar to parasite infection, namely induction of activated IFN-γ secreting Tlymphocytes, could be induced by subunit immunization with NcSRS2 peptides containing the Neospora-specificCTLepitopes (Baszler et al, In preparation) fulfilling objective 2. Both DNA and peptide-based subunit approaches were tested. Only lipopeptide-based NcSRS2 subunits, modified with N-terminal linked palmitic acid to enhance Toll-like receptors 2 and 1 (TLR2-TLR1), stimulated robust antigen-specific T-lymphocyte proliferation, IFN-γ secretion, and serum antibody production across different MHC-IIhaplotypes. The discovery of MHC-II cross-reactive T-cellinducing parasite peptides capable of inducing a potentially protective immune response following subunit immunization in cattle is of significant practical importance to vaccine development to bovine neosporosis. In addition, our findings are more widely applicable in future investigations of protective T-cell, subunit-based immunity against other infectious diseases in outbred cattle populations.

The objectives of this project were to develop procedures and models, based on neural networks, for quality sorting of agricultural produce. Two research teams, one in Purdue University and the other in Israel, coordinated their research efforts on different aspects of each objective utilizing both melons and tomatoes as case studies. At Purdue: An expert system was developed to measure variances in human grading. Data were acquired from eight sensors: vision, two firmness sensors (destructive and nondestructive), chlorophyll from fluorescence, color sensor, electronic sniffer for odor detection, refractometer and a scale (mass). Data were analyzed and provided input for five classification models. Chlorophyll from fluorescence was found to give the best estimation for ripeness stage while the combination of machine vision and firmness from impact performed best for quality sorting. A new algorithm was developed to estimate and minimize training size for supervised classification. A new criteria was established to choose a training set such that a recurrent auto-associative memory neural network is stabilized. Moreover, this method provides for rapid and accurate updating of the classifier over growing seasons, production environments and cultivars. Different classification approaches (parametric and non-parametric) for grading were examined. Statistical methods were found to be as accurate as neural networks in grading. Classification models by voting did not enhance the classification significantly. A hybrid model that incorporated heuristic rules and either a numerical classifier or neural network was found to be superior in classification accuracy with half the required processing of solely the numerical classifier or neural network. In Israel: A multi-sensing approach utilizing non-destructive sensors was developed. Shape, color, stem identification, surface defects and bruises were measured using a color image processing system. Flavor parameters (sugar, acidity, volatiles) and ripeness were measured using a near-infrared system and an electronic sniffer. Mechanical properties were measured using three sensors: drop impact, resonance frequency and cyclic deformation. Classification algorithms for quality sorting of fruit based on multi-sensory data were developed and implemented. The algorithms included a dynamic artificial neural network, a back propagation neural network and multiple linear regression. Results indicated that classification based on multiple sensors may be applied in real-time sorting and can improve overall classification. Advanced image processing algorithms were developed for shape determination, bruise and stem identification and general color and color homogeneity. An unsupervised method was developed to extract necessary vision features. The primary advantage of the algorithms developed is their ability to learn to determine the visual quality of almost any fruit or vegetable with no need for specific modification and no a-priori knowledge. Moreover, since there is no assumption as to the type of blemish to be characterized, the algorithm is capable of distinguishing between stems and bruises. This enables sorting of fruit without knowing the fruits' orientation. A new algorithm for on-line clustering of data was developed. The algorithm's adaptability is designed to overcome some of the difficulties encountered when incrementally clustering sparse data and preserves information even with memory constraints. Large quantities of data (many images) of high dimensionality (due to multiple sensors) and new information arriving incrementally (a function of the temporal dynamics of any natural process) can now be processed. Furhermore, since the learning is done on-line, it can be implemented in real-time. The methodology developed was tested to determine external quality of tomatoes based on visual information. An improved model for color sorting which is stable and does not require recalibration for each season was developed for color determination. Excellent classification results were obtained for both color and firmness classification. Results indicted that maturity classification can be obtained using a drop-impact and a vision sensor in order to predict the storability and marketing of harvested fruits. In conclusion: We have been able to define quantitatively the critical parameters in the quality sorting and grading of both fresh market cantaloupes and tomatoes. We have been able to accomplish this using nondestructive measurements and in a manner consistent with expert human grading and in accordance with market acceptance. This research constructed and used large databases of both commodities, for comparative evaluation and optimization of expert system, statistical and/or neural network models. The models developed in this research were successfully tested, and should be applicable to a wide range of other fruits and vegetables. These findings are valuable for the development of on-line grading and sorting of agricultural produce through the incorporation of multiple measurement inputs that rapidly define quality in an automated manner, and in a manner consistent with the human graders and inspectors.
