The Giacobbe candidates

In these days, I have had the need to run several jobs on a High-Performance Computing (HPC) system. Specifically, I wanted to perform multiple kriging simulations with the GEOFrame hydrological modeling system. GEOFrame already supports parallel processing, so each job can perform multiple simulations simultaneously using a topology file—typically synthetic to avoid unnecessary waits at leaf nodes. To further accelerate the workflow, I split my topology into multiple files and submitted each as part of an array job. Below, I share some useful commands, starting with the PBS file for submitting array jobs. Each simulation file is named grap${PBS_ARRAY_INDEX} , where ${PBS_ARRAY_INDEX} varies from 1 to 90.

Introduction At the end of the summer of 2024 and during autumn, I rediscovered Val Campelle for hiking. Although I had explored these places before, including ski touring during the winter, this time felt different. I was drawn back not just for the physical activity but because my focus shifted from purely sportive motivation to a deeper interest in the history and landscape. Why Val Campelle? At the beginning, I chose this place because of the availability of relatively long circular hikes. After my first excursion, combined with some past memories, I became curious to invest more time exploring this valley and nearby areas such as Val Malene. A Memorable Visit to Val Malene In 2023, I visited Val Malene, and more specifically, I hiked to Costabrunella Lake. Coincidentally, on the same day, a ceremony in memory of partisans was taking place, which significantly increased my interest. I had not known about the presence of partisans during the Seco...

Keeping your paper library well-organized is essential for finding the right document at the right time. A good organization system helps you stay focused on your research, save time, and improve productivity. Over the years, I have experimented with several digital tools for managing bibliographies and taking notes. I’ve read blogs, watched tutorials, and incorporated advice from others, adapting these methods to fit my personal workflow. My requirements are quite common: organizing papers, taking notes, and accessing them seamlessly across devices such as my laptop and tablet. There are many sources for discovering research papers: recommendations from supervisors, references within papers I’ve read, and social media posts about new studies—both on general platforms like X (formerly Twitter) and research-specific networks like ResearchGate. This results in a massive collection of interesting papers to read and organize. My primary tools are Zotero and Notion. I followed Holl...

Organizing my daily tasks and long-term goals is essential as I balance my work, PhD research, personal growth, and leisure time. Over time, I've developed a system that blends analog and digital tools to keep everything in order. Here's an overview of how I use these tools and resources to manage work, track habits, and pursue new interests. Although the system can be a bit complex, it works for me, and I regularly try to update and improve the steps. Bullet Journal for Daily Planning and Habit Tracking My bullet journal is the heart of my organization. I track daily tasks, important thoughts, and monitor new habits. I started using this method after reading The Bullet Journal Method by Ryder Carroll [2] , which serves as the foundation for my approach. I adapt the method to suit my needs. For example, I don’t use it for appointments or general note-taking—only for specific to-dos and habit tracking. My structure includes: Index: This is the ...

A basin network can be seen as a graph, specifically as a directed acyclic tree . In GEOframe , the topology of the basins, which describes the direction of the flow and the interconnections of the basins, is usually saved in a text file with two columns: the first column represents the origin basin , and the second column represents the target basin . The 0 is used to mark the outlet of the network. For example: 8 7 7 4 6 5 5 4 4 3 3 2 2 1 1 0 The 0 mark the outlet. In my work, I've encountered the need to manipulate basin networks so verifying the topological correctness of these new graphs is crucial. To accomplish this task, I chose the NetworkX Python library. This library facilitates a variety of tasks—such as cutting the network, iterating through the network, and comparing two or more networks within the same watershed—thanks to its class structure, specifically the Graph class. As a result, I've developed some functions for basic operations on the network and sha...

The Beginning It's been a long time since I first heard about Julia . Despite my interest, I never got around to actually studying it. That changed recently when I attended a short course on Julia at the last EGU General Assembly . Inspired by what I learned, I returned home determined to dive into programming with Julia. First Steps I started with a basic book on Julia, aiming to build a solid foundation. The simplicity and power of the language fascinated me, and soon, I felt ready to take a more hands-on approach. My Project: A Julia Package As I gained confidence, I began writing my own package. This project is still a work in progress on github. The package includes: Reading Time Series: It can read a time series from a CSV file, handling special formatting and metadata. Goodness of Fit Functions. Graph Operations on river networks.(in progres) Geometry/Geography Operations. Focus on Geography In this blog post, I want to delve into the last point —...
