ZRG: A High Resolution 3D Residential Rooftop Geometry Dataset for Machine Learning

In this paper we present the Zeitview Rooftop Geometry (ZRG) dataset. ZRG contains thousands of samples of high resolution orthomosaics of aerial imagery of residential rooftops with corresponding digital surface models (DSM), 3D rooftop wireframes, and multiview imagery generated point clouds for the purpose of residential rooftop geometry and scene understanding. We perform thorough benchmarks to illustrate the numerous applications unlocked by this dataset and provide baselines for the tasks of roof outline extraction, monocular height estimation, and planar roof structure extraction

Theology of God’s presence in Benedict XVI’s catechesis regarding a prayer

The paper describes Benedict XVI’s reflection on the presence of God, included in the catechesis regarding a prayer. As mentioned in the beginning of the Pope did not make a separate catechesis regarding the presence of God, but this topic appeared on most of his catechesis “the school of praying”. A very practical concept emerges from the arguments the Pope included on the topic of God’s presence. Benedict XVI shows a path of finding a desire of God’s presence within, through serving others and also through inspiring others for their own discoveries

Miłosierny Samarytanin w refleksji teologicznej Josepha Ratzingera/Bendykta XVI

In his interview with Jaques Servais the pope Benedict XVI spoke in a very positive way about the fact that pope Francis preaches so often about God’s mercy. Commenting on this pastoral method, he said that the story of the Good Samaritan is especially attractive for a modern man. According to him, it stems from the inner desire of the heart to meet the Good Samaritan who will take care of him and lead him to safety. In the end, this is a desire to experience God’s mercy and loving care. This article looks at other teachings of Joseph Ratzinger/Benedict XVI on the parable of the Good Samaritan. The pope invites us to set out on the way of forming our hearts by asking ourselves “How to live?” After cleaning up our relationships of love with God and with other people we should stop analyzing who do I own love and become neighbors to others. The process of shaping our hearts will be complete once our hearts become “the heart that sees”. Sees the needs of others and notices the spiritual poverty. In both of those situations the Christian who lives the program of the Good Samaritan will try to fulfill those needs

Teologia modlitwy chrześcijańskiej w pismach Josepha Ratzingera/Benedykta XVI

The key to understanding the theological thought of Joseph Ratzinger/ Benedict XVI is Jesus Christ. The future pope built his dogmatic and fundamental theology discourse around the Son of God. His focus on Christ is also noticeable in his reflection on Christian prayer. Therefore, this dissertation is opened by the Prologue which presents the results of studies and formulates the key to hermeneutic interpretation of Ratzinger’s theology of prayer and at the same time the key to this dissertation. It introduces how Christology of prayer stems from spiritual Christology. Christology is born from Jesus’s prayer. His prayer is the source of Christian prayer, it is the fruit of Jesus’s whole life, his Incarnation and Passover; prayer is based on experiencing the process of adopting the attitude of the Son of God. (...) The final part of the dissertation summarizes the findings and concludes that there is a consistent theology of prayer present in the multitude of Joseph Ratzinger’s/ Benedict XVI writings

Barely-Visible Surface Crack Detection for Wind Turbine Sustainability

The production of wind energy is a crucial part of sustainable development and reducing the reliance on fossil fuels. Maintaining the integrity of wind turbines to produce this energy is a costly and time-consuming task requiring repeated inspection and maintenance. While autonomous drones have proven to make this process more efficient, the algorithms for detecting anomalies to prevent catastrophic damage to turbine blades have fallen behind due to some dangerous defects, such as hairline cracks, being barely-visible. Existing datasets and literature are lacking and tend towards detecting obvious and visible defects in addition to not being geographically diverse. In this paper we introduce a novel and diverse dataset of barely-visible hairline cracks collected from numerous wind turbine inspections. To prove the efficacy of our dataset, we detail our end-to-end deployed turbine crack detection pipeline from the image acquisition stage to the use of predictions in providing automated maintenance recommendations to extend the life and efficiency of wind turbines
