Izolirana i nestala banijska naselja
IN CROATIAN: Ruralna naselja u kontinentalnoj Hrvatskoj obilježena su snažnom depopula[1]cijom, prometnom izoliranošću i velikim brojem napuštenih i praznih mjesta. Područje Banije desetljećima je posebno izloženo snažnoj depopulaciji. Od 195 nenaseljenih mjesta u Hrvatskoj 2021. godine, čak njih 13 je na području Ba[1]nije. Banijska napuštena naselja, u kojima nitko više ne živi pored ruševina ili tragova kuća i okućnica, s devastiranom infrastrukturom, nepostojećim jav[1]nim prijevozom i, na kraju, u potpuno zapuštenim ruralnim krajolicima, svje[1]doče demografskom slomu, izumiranju i nestajanju. Raznoliki razlozi (migra[1]cije, ratovi i katastrofe, ekonomski i politički razlozi) doveli su do društvene i kulturne izolacije. U ovome radu prikazat će se prazna i napuštena naselja (Baturi, Bišćanovo, Brubno, Donja Trstenica, Donji Selkovac, Gornje Jame, Turčenica, Kobiljak, Ostojići, Zut, Bukovica i Mala Vranovina) pomoću doku[1]mentiranja devastiranih i danas jedva vidljivih ostataka materijalne kulture. Uz to analizirat će se „svakodnevica u prošlosti“ korištenjem arhivske građe o stanovnicima i životu u prošlosti te pomoću iskustava, doživljaja, sjećanja i privatne arhive (sačuvani predmeti, fotografije) njihovih bivših stanovnika. --------------- IN ENGLISH: Rural settlements in Continental Croatia are characterized by severe depopulation, traffic isolation, and a large number of abandoned and empty settlements. The Banija Region has been particularly affected by severe depopulation for decades. Of the 195 uninhabited settlements in Croatia in 2021, as many as 13 are in the Banija Region. Uninhabited and abandoned settlements, where no one lives anymore next to the ruins or traces of houses and gardens, with devastated or destroyed infrastructure, non-existent public transport, and completely neglected rural landscapes testify to demographic collapse, extinction, and desertion. Various reasons (migrations, wars and disasters, economic and political reasons) have led to social and cultural isolation. In this paper, we will show empty and abandoned settlements (Baturi, Bišćanovo, Brubno, Donja Trstenica, Donji Selkovac, Gornje Jame, Turčenica, Kobiljak, Ostojići, Zut, Bukovica, and Mala Vranovina) by documenting the devastated and barely visible remains of material culture. In addition, we will analyse “everyday life in the past” using archival material about life in the past, and through the experiences, memories, stories, and private archives (preserved objects, photos) of their former residents

Computational Methods in Multi-Messenger Astrophysics using Gravitational Waves and High Energy Neutrinos
This dissertation seeks to describe advancements made in computational methods for multi-messenger astrophysics (MMA) using gravitational waves GW and neutrinos during Advanced LIGO (aLIGO)’s first through third observing runs (O1-O3) and, looking forward, to describe novel computational techniques suited to the challenges of both the burgeoning MMA field and high-performance computing as a whole.
The first two chapters provide an overview of MMA as it pertains to gravitational wave/high energy neutrino (GWHEN) searches, including a summary of expected astrophysical sources as well as GW, neutrino, and gamma-ray detectors used in their detection. These are followed in the third chapter by an in-depth discussion of LIGO’s timing system, particularly the diagnostic subsystem, describing both its role in MMA searches and the author’s contributions to the system itself.
The fourth chapter provides a detailed description of the Low-Latency Algorithm for Multi-messenger Astrophysics (LLAMA), the GWHEN pipeline developed by the author and used in O2 and O3. Relevant past multi-messenger searches are described first, followed by the O2 and O3 analysis methods, the pipeline’s performance, scientific results, and finally, an in-depth account of the library’s structure and functionality. In particular, the author’s high-performance multi-order coordinates (MOC) HEALPix image analysis library, HPMOC, is described. HPMOC increases performance of HEALPix image manipulations by several orders of magnitude vs. naive single-resolution approaches while presenting a simple high-level interface and should prove useful for diverse future MMA searches. The performance improvements it provides for LLAMA are also covered.
The final chapter of this dissertation builds on the approaches taken in developing HPMOC, presenting several novel methods for efficiently storing and analyzing large data sets, with applications to MMA and other data-intensive fields. A family of depth-first multi-resolution ordering of HEALPix images — DEPTH9, DEPTH19, and DEPTH40 — is defined, along with algorithms and use cases where it can improve on current approaches, including high-speed streaming calculations suitable for serverless compute or FPGAs.
For performance-constrained analyses on HEALPix data (e.g. image analysis in multi-messenger search pipelines) using SIMD processors, breadth-first data structures can provide short-circuiting calculations in a data-parallel way on compressed data; a simple compression method is described with application to further improving LLAMA performance.
A new storage scheme and associated algorithms for efficiently compressing and contracting tensors of varying sparsity is presented; these demuxed tensors (D-Tensors) have equivalent asymptotic time and space complexity to optimal representations of both dense and sparse matrices, and could be used as a universal drop-in replacement to reduce code complexity and developer effort while improving performance of existing non-optimized numerical code. Finally, the big bucket hash table (B-Table), a novel type of hash table making guarantees on data layout (vs. load factor), is described, along with optimizations it allows for (like hardware acceleration, online rebuilds, and hard realtime applications) that are not possible with existing hash table approaches. These innovations are presented in the hope that some will prove useful for improving future MMA searches and other data-intensive applications

HERITAGE 2022. International Conference on Vernacular Heritage: Culture, People and Sustainability
Vernacular architecture, tangible and intangible heritage of great importance to European and global culture, represents the response of a society culturally linked to its territory, in terms of climate and landscape. Its construction features are born from the practical experience of the inhabitants, making use of local materials, taking into consideration geographical conditions and cultural, social and constructive traditions, based on the conditions of the surrounding nature and habitat. Above all, it plays an essential role in contemporary society as it is able to teach us important principles and lessons for a respectful sustainable architecture.
Vernacular Heritage: Culture, People and Sustainability will be a valuable source of information for academics and professionals in the fields of Environmental Science, Civil Engineering, Construction and Building Engineering and ArchitectureMileto, C.; Vegas López-Manzanares, F.; Cristini, V.; García Soriano, L.

EOLANG and -calculus
Object-oriented programming (OOP) is one of the most popular paradigms used
for building software systems. However, despite its industrial and academic
popularity, OOP is still missing a formal apparatus similar to
-calculus, which functional programming is based on. There were a
number of attempts to formalize OOP, but none of them managed to cover all the
features available in modern OO programming languages, such as C++ or Java. We
have made yet another attempt and created -calculus. We also created
EOLANG (also called EO), an experimental programming language based on
-calculus

[Resumen] Las Jornadas de Automática (JA) son el evento más importante del Comité Español de Automática (CEA), entidad científico-técnica con más de cincuenta años de vida y destinada a la difusión e implantación de la Automática en la sociedad. Este año se celebra la cuadragésima tercera edición de las JA, que constituyen el punto de encuentro de la comunidad de Automática de nuestro país. La presente edición permitirá dar visibilidad a los nuevos retos y resultados del ámbito, y su uso en un gran número de aplicaciones, entre otras, las energías renovables, la bioingeniería o la robótica asistencial. Además de la componente científica, que se ve reflejada en este libro de actas, las JA son un punto de encuentro de las diferentes generaciones de profesores, investigadores y profesionales, incluyendo la componente social que es de vital importancia.
Esta edición 2022 de las JA se celebra en Logroño, capital de La Rioja, región mundialmente conocida por la calidad de sus vinos de Denominación de Origen y que ha asumido el desafío de poder ganar competitividad a través de la transformación verde y digital. Pero también por ser la cuna del castellano e impulsar el Valle de la Lengua con la ayuda de las nuevas tecnologías, entre ellas la Automática Inteligente. Los organizadores de estas JA, pertenecientes al Área de Ingeniería de Sistemas y Automática del Departamento de Ingeniería Eléctrica de la Universidad de La Rioja (UR), constituyen un pilar fundamental en el apoyo a la región para el estudio, implementación y difusión de estos retos.
Esta edición, la primera en formato íntegramente presencial después de la pandemia de la covid-19, cuenta con más de 200 asistentes y se celebra a caballo entre el Edificio Politécnico de la Escuela Técnica Superior de Ingeniería Industrial y el Monasterio de Yuso situado en San Millán de la Cogolla, dos marcos excepcionales para la realización de las JA. Como parte del programa científico, dos sesiones plenarias harán hincapié, respectivamente, sobre soluciones de control para afrontar los nuevos retos energéticos, y sobre la calidad de los datos para una inteligencia artificial (IA) imparcial y confiable. También, dos mesas redondas debatirán aplicaciones de la IA y la implantación de la tecnología digital en la actividad profesional. Adicionalmente, destacaremos dos clases magistrales alineadas con tecnología de última generación que serán impartidas por profesionales de la empresa. Las JA también van a albergar dos competiciones: CEABOT, con robots humanoides, y el Concurso de Ingeniería de Control, enfocado a UAVs. A todas estas actividades hay que añadir las reuniones de los grupos temáticos de CEA, las exhibiciones de pósteres con las comunicaciones presentadas a las JA y los expositores de las empresas. Por último, durante el evento se va a proceder a la entrega del “Premio Nacional de Automática” (edición 2022) y del “Premio CEA al Talento Femenino en Automática”, patrocinado por el Gobierno de La Rioja (en su primera edición), además de diversos galardones enmarcados dentro de las actividades de los grupos temáticos de CEA.
Las actas de las XLIII Jornadas de Automática están formadas por un total de 143 comunicaciones, organizadas en torno a los nueve Grupos Temáticos y a las dos Líneas Estratégicas de CEA. Los trabajos seleccionados han sido sometidos a un proceso de revisión por pares

Decision Support Systems
Decision support systems (DSS) have evolved over the past four decades from theoretical concepts into real world computerized applications. DSS architecture contains three key components: knowledge base, computerized model, and user interface. DSS simulate cognitive decision-making functions of humans based on artificial intelligence methodologies (including expert systems, data mining, machine learning, connectionism, logistical reasoning, etc.) in order to perform decision support functions. The applications of DSS cover many domains, ranging from aviation monitoring, transportation safety, clinical diagnosis, weather forecast, business management to internet search strategy. By combining knowledge bases with inference rules, DSS are able to provide suggestions to end users to improve decisions and outcomes. This book is written as a textbook so that it can be used in formal courses examining decision support systems. It may be used by both undergraduate and graduate students from diverse computer-related fields. It will also be of value to established professionals as a text for self-study or for reference
