    Model for Spatiotemporal Crime Prediction with Improved Deep Learning

    No full text
    Crime is hard to anticipate since it occurs at random and can occur anywhere at any moment, making it a difficult issue for any society to address. By analyzing and comparing eight known prediction models: Naive Bayes, Stacking, Random Forest, Lazy:IBK, Bagging, Support Vector Machine, Convolutional Neural Network, and Locally Weighted Learning – this study proposed an improved deep learning crime prediction model using convolutional neural networks and the xgboost algorithm to predict crime. The major goal of this research is to provide an improved crime prediction model based on previous criminal records. Using the Boston crime dataset, where our larceny crime dataset was extracted, exploratory data analysis (EDA) is used to uncover patterns and explain trends in crimes. The performance of the proposed model on the basis of accuracy, recall, and f-measure was 100% outperforming the other models used in this study. The analysis of the proposed model and prediction can aid security services in making better use of their resources, anticipating crime at a certain time, and serving the society better

    We exposed Dorper-cross ewes at 120–135 days of gestation to a hot (40°C, 60% relative humidity) and a cold (4°C, 90% relative humidity) environ- ment and to treadmill exercise (2.1 km/h, 5° gradient) and measured fetal lamb and ewe body temperatures using pre- viously implanted abdominal radiotelemeters. When ewes were exposed to 2 h of heat or 30 min of exercise, body temperature rose less in the fetus than in the mother, such that the difference between fetal and maternal body temper- ature, on average 0.6°C before the thermal stress, fell signif- icantly by 0.54 0.06°C (SE, n 8) during heat exposure and by 0.21 0.08°C (n 7) during exercise. During 6 h of maternal exposure to cold, temperature fell significantly less in the fetus than in the ewe, and the difference between fetal and maternal body temperature rose to 1.16 0.26°C (n 9). Thermoregulatory strategies used by the pregnant ewe for thermoregulation during heat or cold exposure appear to protect the fetus from changes in its thermal environment.Peer reviewedfinal article publishedfetussheephyperthermiafetomaternal thermal gradien

    Development and validation of evaporation model for a multi-component fuel considering volume-average internal mass and enthalpy

    No full text
    We developed a droplet evaporation model for a multi-component fuel, considering the nonuniform dis-tributions of both mass fraction and temperature inside multi-component fuel droplet. The distribution equations satisfy the conservation of droplet mass and enthalpy. We proposed mass fraction and temper-ature distribution equations inside a droplet to accurately determine variations between the numerical assumptions of a liquid phase and a gas phase. We found that an obvious gradient appears in the mass fraction and temperature distribution profiles at various ambient temperatures. To verify the accuracy of the developed model, we further compared the predicted droplet lifetimes with the experimental results at various ambient temperatures. The consideration of the pre-evaporation process led to more accu-rate droplet lifetime prediction using the present model. We also investigated the differences between the present model and the uniform distribution model. The difference in the predicted droplet lifetime becomes more than 10% at practical spray combustion conditions. Thus, internal distribution of mass fraction ad temperature must be considered in practical spray combustion simulations. (c) 2021 Elsevier Ltd. All rights reserved

    Comparison between a bottom-up and a top-down approach for the compilation of environmental extensions for the Multi-Region Input-Output database EUREGIO

    No full text
    In this thesis two different approaches for the construction of environmental extensions compatible with the MRIO database EUREGIO are compared alongside with the latest liter- ature on consumption-based accounts. To date, few studies have focused on the provision of sub-national accounts at the NUTS2 level of detail and never production-based accounts have been compiled for the European NUTS2 level of detail. The first approach described as the bottom-up approach uses TNO’s MACC emission inventory for the year 2010 which compiles spatially explicit emission data at the source for 9 different pollutants across Europe with a 0.1àx 0.05à longitude-latitude resolution for over 250 source sectors. The second approach described as the top-down approach uses NAMEA data from EUROSTAT by disaggregating it to the regional level following a linear approach based on the regional economic output of a sector compared to the national economic output of the same sector. The two differ- ent approaches for the compilation of environmental extensions are compared both at the production-based accounts and the consumption-based accounts level mapping the existing relative difference across sectors at the national and regional level. The level of heterogeneity in the magnitude of the relative difference of the accounts increases proportionally with geo- graphic detail underlying the fact that a bottom-up construction is able to better grasp the regional scale. This is ever more prominent when looking at particular sectors such as the utilities sectors ss2 and ss5. Of the analysed NUTS2 European regions, the carbon footprint of 74% of the regions presents an upwards deviation of more than 4% compared to the bench- mark study with footprints ranging from 2 to 46 tCO2/cap for Umbria (IT) and Souther Finland (FI) respectively. The obtained results highlight the advantage of the bottom-up approach for more accurate distribution of the emissions at the regional scale from industries to the consumers resonating with similar conclusions from other authors. Despite this, several recommendations are made to improve the quality of the bottom-up approach with possible future applications.The Master's programme Industrial Ecology is jointly organised by Leiden University and Delft University of Technology.Industrial Ecolog

    The author of the present study deals with the contemporary state of memoir liter-ature based on the analysis of some recent Czech and Slovak memoirs. The prob-lem of contemporary memoir texts is connected with the position of the memoirist in the society, his courage and openness. In the past the author dealt with the chronicle and the novel-chronicle and with the whole layer of genres situated on the boundary of fiction and nonfiction (diary, essay, reportage, column, memoirs etc.). His typology of the memoir literature is based on the three-level structure (theme, structure and genre, narrative strategy). He prefers to call contemporary memoir literature because its structure is very heterogeneous, and the fear of the memoirist, his anxiety and aversion to express too radical views lead to soft focus, uncertainty, evasiveness, the lack of clear opinions – there are the characteristic features of contemporary memoir literature as a reflection of the state of the world and the man of the second decade of the 21 century. These features are being demonstrated at the works written by Czech and Slovak writers, significant personal-ities of culture, politicians, artists etc. The postmodernist understanding of virtuality and uncertainty, ambivalence of the truth and the lie reflect the pressure of contem-porary world as rationally inexplicable and generally incomprehensible in the sense of the knowledge of the principles of its construction and functioning which is asso-ciated with the problem of the evident and hidden power. In such a world the human being feels alone and lost

    A Practical Guide to the Therapy of Narcolepsy and Hypersomnia Syndromes

    No full text
    # The Author(s) 2012. This article is published with open access at Springerlink.com Summary Narcolepsy and other syndromes associated with excessive daytime sleepiness can be challenging to treat. New classifications now distinguish narcolepsy/hypo-cretin deficiency (also called type 1 narcolepsy), a lifelong disorder with well-established diagnostic procedures and etiology, from other syndromes with hypersomnolence of unknown causes. Klein-Levin Syndrome, a periodic hyper-somnia associated with cognitive and behavioral abnormal-ities, is also considered a separate entity with separate therapeutic protocols. Non hypocretin-related hypersomnia syndromes are diagnoses of exclusion. These diagnoses are only made after eliminating sleep deprivation, sleep apnea, disturbed nocturnal sleep, and psychiatric comorbidities as the primary cause of daytime sleepiness. The treatment of narcolepsy/hypocretin deficiency is well-codified, and involves pharmacotherapies using sodium oxybate, stimu-lants, and/or antidepressants, plus behavioral modifications. These therapies are almost always needed, and the risk-to-benefit ratio is clear, notably in children. Detailed knowledge of the pharmacological profile of each compound is needed to optimize use. Treatment for other syndromes with hypersom-nolence is more challenging and less codified. Preferably, therapy should be conservative (such as modafinil, atomox-etine, behavioral modifications), but it may have to be more aggressive (high-dose stimulants, sodium oxybate, etc.) on a case-by-case, empirical trial basis. As cause and evolution are unknown in these conditions, it is important to challenge diagnosis and therapy over time, keeping in mind the possibility of tolerance and the development of stimulant addiction. Kleine-Levin Syndrome is usually best left untreat-ed, although lithium can be considered in severe cases with frequent episodes. Guidelines are provided based on the liter-ature and personal experience of the author
