A linguistic geometry for 3D strategic planning

This paper is a new step in the development and application of the Linguistic Geometry. This formal theory is intended to discover the inner properties of human expert heuristics, which have been successful in a certain class of complex control systems, and apply them to different systems. In this paper we investigate heuristics extracted in the form of hierarchical networks of planning paths of autonomous agents. Employing Linguistic Geometry tools the dynamic hierarchy of networks is represented as a hierarchy of formal attribute languages. The main ideas of this methodology are shown in this paper on the new pilot example of the solution of the extremely complex 3D optimization problem of strategic planning for the space combat of autonomous vehicles. This example demonstrates deep and highly selective search in comparison with conventional search algorithms

Network languages for intelligent control

AbstractIn order to discover the inner properties of human expert heuristics, which were successful in a certain class of complex control systems, and apply them to different systems, we develop a formal theory: the Linguistic Geometry. This research includes the development of syntactic tools for knowledge representation and reasoning about large-scale hierarchical complex systems. It relies on the formalization of search heuristics of high-skilled human experts, which allow one to decompose a complex system into a hierarchy of subsystems, and thus solve intractable problems reducing the search. The hierarchy of subsystems is represented as a hierarchy of formal attribute languages. This paper includes a brief survey of the Linguistic Geometry and a detailed comparative description of two comprehensive examples of solving optimization problems for military autonomous agents with cooperative and opposing interests operating on surface and in space. These examples include actual generation of the hierarchy of languages and demonstrate the drastic reduction of search in comparison with conventional search algorithms

A linguistic geometry for space applications

We develop a formal theory, the so-called Linguistic Geometry, in order to discover the inner properties of human expert heuristics, which were successful in a certain class of complex control systems, and apply them to different systems. This research relies on the formalization of search heuristics of high-skilled human experts which allow for the decomposition of complex system into the hierarchy of subsystems, and thus solve intractable problems reducing the search. The hierarchy of subsystems is represented as a hierarchy of formal attribute languages. This paper includes a formal survey of the Linguistic Geometry, and new example of a solution of optimization problem for the space robotic vehicles. This example includes actual generation of the hierarchy of languages, some details of trajectory generation and demonstrates the drastic reduction of search in comparison with conventional search algorithms

Revisiting Major Discoveries in Linguistic Geometry with Mosaic Reasoning

AbstractIn discovering the nature of the Primary Language of the human brain introduced by J. von Neumann, two components have been investigated. The first component is Linguistic Geometry (LG), the algorithm of optimizing war-fighting strategies. LG's universal applicability in various domains and its power in generating human-like strategies suggested that LG should be a component of the Primary Language. The second component is the algorithm of inventing new algorithms. This paper researches the role of mosaic reasoning, a component of the Algorithm of Discovery, in obtaining the key results in LG such as the algorithms for generating trajectories and zones

Systematic review of the clinical pattern of hypersensitivity reactions caused by carboplatin in two geographic areas: Massachusetts and Spain

Traballo Fin de Grao en Medicina. Curso 2020-2021INTRODUCCIÓN: La creciente disponibilidad de fármacos y el incremento de su uso ha implicado un aumento en las reacciones de hipersensibilidad. Las reacciones de hipersensibilidad frente al carboplatino pueden implicar la retirada del fármaco, conllevando a que el paciente no pueda recibir la primera, o incluso, la única línea terapéutica. La desensibilización es un procedimiento que permite al paciente recibir, de manera segura el fármaco, cuando no existen alternativas similares. Esta técnica se fundamenta en la administración controlada de dosis crecientes de fármaco, induciendo en el paciente, una tolerancia temporal, permitiendo así que pueda continuar con su tratamiento. OBJETIVO: Analizar el patrón clínico de las reacciones de hipersensibilidad a carboplatino, centrándonos en los síntomas y en la patología tumoral de base, así como el análisis de los síntomas observados durante los procedimientos de desensibilización DISEÑO Y FUENTES DE DATOS: Revisión sistemática de los artículos publicados en PubMed desde 2015 hasta diciembre de 2020 en España y Massachusetts RESULTADOS: Esta revisión se basa en la comparación de 5 artículos, en la que pacientes con diversas patologías tumorales han recibido carboplatino. Los síntomas cutáneos aparecen en el 100% de los pacientes, siendo el eritema la entidad más frecuente. CONCLUSIÓN: En la reacción de hipersensibilidad inicial a carboplatino la sintomatología cutánea es la más prevalente (eritema y prurito), seguido de sintomatología respiratoria, cardiovascular y gastrointestinal. Los pacientes afectos de tumor de ovario presentan especial susceptibilidad a desarrollar una reacción de hipersensibilidad. El procedimiento de desensibilización es seguro, siendo poco frecuente la aparición de reacciones durante el mismo, las cuales, en caso de existir, suelen ser de menor gravedad que la reacción inicial. En relación con el carboplatino, la mayoría de los síntomas observados son cutáneosINTRODUCTION: The increasing availability of pharmaceutical drugs and their use has implied an increase in hypersensitivity reactions. Hypersensitivity reactions to carboplatin could lead to the discontinuation of the drug administration, even when it is the first or only therapeutic line. Desensitization is a procedure that allows the patient to receive the pharmaceutical drug in a safe manner when there are no other similar alternatives. This technique is based on a controlled administration of incremental doses of the drug, inducing a temporary tolerance in the patient, thus allowing them to continue with the treatment. OBJECTIVE: To analyze the clinical pattern of hypersensitivity reactions to carboplatin focusing on the symptoms and the underlying tumor pathology, as well as the analysis of the symptoms observed during desensitization procedures. DESIGN AND DATA SOURCES: Systematic review of articles published in PubMed from 2015 to December 2020 in Spain and / or Massachusetts area. RESULTS: This review is based on the comparison of 5 articles, in which patients with various tumor pathologies have been administered carboplatin. Skin symptoms appear in 100% of patients, erythema being the most frequent one. CONCLUSION: The initial hypersensitivity reaction to carboplatin consists mainly of cutaneous symptoms (erythema and pruritus) but also respiratory, cardiovascular and gastrointestinal symptoms are shown, although to a minor extent. Patients with ovarian tumors are particularly susceptible to developing a hypersensitivity reaction. Desensitization procedure is safe and the appearance of reactions during the process is infrequent. If reactions occur, they are usually less serious than the initial reaction. In the case of carboplatin, most of the observed symptoms are cutaneou

Ach: IPC for Real-Time Robot Control

We present a new Inter-Process Communication (IPC) mechanism and library. Ach is uniquely suited for coordinating perception, control drivers, and algorithms in real-time systems that sample data from physical processes. Ach eliminates the Head-of-Line Blocking problem for applications that always require access to the newest message. Ach is efficient, robust, and formally verified. It has been tested and demonstrated on a variety of physical robotic systems. Finally, the source code for Ach is available under an Open Source BSD-style license

Navigation Among Movable Obstacles: Real-Time Reasoning in Complex Environments

Electronic version of an article published as International Journal of Humanoid Robotics, Vol. 2, No. 4, December, 2005 pp. 479-504; DOI: 10.1142/S0219843605000545 ; © World Scientific Publishing Company ; http://www.worldscinet.com/ijhr/ijhr.shtmlIn this paper, we address the problem of Navigation Among Movable Obstacles (NAMO): a practical extension to navigation for humanoids and other dexterous mobile robots. The robot is permitted to reconfigure the environment by moving obstacles and clearing free space for a path. This paper presents a resolution complete planner for a subclass of NAMO problems. Our planner takes advantage of the navigational structure through state-space decomposition and heuristic search. The planning complexity is reduced to the difficulty of the specific navigation task, rather than the dimensionality of the multi-object domain. We demonstrate real-time results for spaces that contain large numbers of movable obstacles. We also present a practical framework for single-agent search that can be used in algorithmic reasoning about this domain

The Motion Grammar: Linguistic Perception, Planning, and Control

We present the Motion Grammar: a novel unified representation for task decomposition, perception, planning, and hybrid control that provides a computationally tractable way to control robots in uncertain environments with guarantees on completeness and correctness. The grammar represents a policy for the task which is parsed in real-time based on perceptual input. Branches of the syntax tree form the levels of a hierarchical decomposition, and the individual robot sensor readings are given by tokens. We implement this approach in the interactive game of Yamakuzushi on a physical robot resulting in a system that repeatably competes with a human opponent in sustained game-play for matches up to six minutes

Design and Performance of Thermal Energy Storage Module using High Thermal Conductivity Phase Change Composite Material

HVAC (Heating, Ventilation and Cooling) accounts for approximately 15-30% of a commercial building’s electricity cost and about 20-40% of electricity consumption. Electricity costs charged by the utilities companies for commercial building customers includes consumption charges ($/kWh) and demand charges ($/kW) depending on the time of use (TOU) charges. Thus, there is great interest to reduce the electricity consumption charges and demand charges by using new energy efficient technologies and products. One such product is a thermal energy storage (TES) system using a phase change material (PCM) to offset the cooling costs associated with air-conditioning systems by reducing the electricity consumption during peak time periods. A patented phase change composite (PCC) TES material was developed that has high thermal conductivity and adjustable phase change temperature. Compared to ice, the PCC TES system is capable of higher heat transfer rate and has lower system and operational costs. Proof of concept demonstration and working prototype results of a PCC TES system were successfully completed. Results show that a PCC TES system can be designed for a commercial building and maintain high efficiency with either low or high discharge rates. Techno-economic analysis for peak shaving or peak load shifting of a commercial air-conditioning system was studied, comparing Ice and PCC TES system. Results show that a PCC TES system can compete with Ice TES system with favorable ROI (return on investment).
