Sbert M. Point-based modeling from a single image
No full textAbstract. The complexity of virtual environments has grown spectacularly over the recent years, mainly thanks to the use of the currently cheap high performance graphics cards. As the graphics cards improve the performance and the geometry complexity grows, many of the objects present in the scene only project to a few pixels on the screen. This represents a waste in computing effort for the transforming and clipping of maybe a lot of polygons that could be substituted by a simple point or a small set of points. Recently, efficient rendering algorithms for point models have been proposed. However, little attention has been focused on building a point-based modeler, using the advantages that such a representation can provide. In this paper we present a modeler that can generate 3D geometry from an image, completely built on points. It takes as input an image and creates a point-based representation from it. Then, a set of operators allow to modify the geometry in order to produce 3D geometry from the image. With our system it is possible to generate in short time complex geometries that would be difficult to model with a polygon-based modeler.
A review and comparative study of cancer detection using machine learning : SBERT and SimCSE application
No full textAVAILABILITY OF DATA AND MATERIALS : The data can be accessed at the host database (The European Genome-phenome Archive at the European Bioinformatics
Institute, accession number: EGAD00001004582 Data access).BACKGROUND : Using visual, biological, and electronic health records data as the sole
input source, pretrained convolutional neural networks and conventional machine
learning methods have been heavily employed for the identification of various malignancies.
Initially, a series of preprocessing steps and image segmentation steps are
performed to extract region of interest features from noisy features. Then, the extracted
features are applied to several machine learning and deep learning methods for the
detection of cancer.
METHODS : In this work, a review of all the methods that have been applied to develop
machine learning algorithms that detect cancer is provided. With more than 100 types
of cancer, this study only examines research on the four most common and prevalent
cancers worldwide: lung, breast, prostate, and colorectal cancer. Next, by using
state-of-the-art sentence transformers namely: SBERT (2019) and the unsupervised
SimCSE (2021), this study proposes a new methodology for detecting cancer. This
method requires raw DNA sequences of matched tumor/normal pair as the only input.
The learnt DNA representations retrieved from SBERT and SimCSE will then be sent to
machine learning algorithms (XGBoost, Random Forest, LightGBM, and CNNs) for classification.
As far as we are aware, SBERT and SimCSE transformers have not been applied
to represent DNA sequences in cancer detection settings.
RESULTS : The XGBoost model, which had the highest overall accuracy of 73 ± 0.13 %
using SBERT embeddings and 75 ± 0.12 % using SimCSE embeddings, was the best
performing classifier. In light of these findings, it can be concluded that incorporating
sentence representations from SimCSE’s sentence transformer only marginally
improved the performance of machine learning models.The South African Medical Research Council (SAMRC) through its Division of Research Capacity Development under the Internship Scholarship Program from funding received from the South African National Treasury.https://bmcbioinformatics.biomedcentral.comam2024Computer ScienceSchool of Health Systems and Public Health (SHSPH)Non
The transformation of environmental law into ecological law
No full textHuman activities are damaging the ecological foundations of life. We are currently facing a
broad and comprehensive global ecological crisis. In the age of Anthropocene, humanity is
called to recognize its responsibility to act in order to address such ecological challenge, leaving
behind old paradigms and models, and moving towards a new legal approach to human
development in harmony with Nature.
A new attitude is needed to tackle the global ecological crisis. This should consist in the
transformation of environmental law into ecological law. The transformation should be based
on three main changes, including a new main objective, a new reference approach and a new
key paradigm. The new main objective should consist in ecological integrity as a pre-requisite
for Nature protection. The new reference approach should overcome the dichotomy between
an anthropocentric and an eco-centric approach. The new key paradigm should promote a shift
from a culture of domination to a culture of respect.
In order to achieve the transformation from environmental law into ecological law, it will be
necessary to re-assess the existing corpus of environmental law, and indeed all of
contemporary law, relying upon a revised set of principles, objectives and tools

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods

Simulation of thermal plant optimization and hydraulic aspects of thermal distribution loops for large campuses
No full textFollowing an introduction, the author describes Texas A&M University and its utilities system. After that, the author presents how to construct simulation models for chilled water and heating hot water distribution systems. The simulation model was used in a $2.3 million Ross Street chilled water pipe replacement project at Texas A&M University. A second project conducted at the University of Texas at San Antonio was used as an example to demonstrate how to identify and design an optimal distribution system by using a simulation model. The author found that the minor losses of these closed loop thermal distribution systems are significantly higher than potable water distribution systems. In the second part of the report, the author presents the latest development of software called the Plant Optimization Program, which can simulate cogeneration plant operation, estimate its operation cost and provide optimized operation suggestions. The author also developed detailed simulation models for a gas turbine and heat recovery steam generator and identified significant potential savings. Finally, the author also used a steam turbine as an example to present a multi-regression method on constructing simulation models by using basic statistics and optimization algorithms. This report presents a survey of the author??s working experience at the Energy Systems Laboratory (ESL) at Texas A&M University during the period of January 2002 through March 2004. The purpose of the above work was to allow the author to become familiar with the practice of engineering. The result is that the author knows how to complete a project from start to finish and understands how both technical and nontechnical aspects of a project need to be considered in order to ensure a quality deliverable and bring a project to successful completion. This report concludes that the objectives of the internship were successfully accomplished and that the requirements for the degree of Degree of Engineering have been satisfied

No full textIncludes author's vita"Submitted to the College of Engineering of Texas A&M University in partial
fulfillment of the requirement for the degree of Doctor of Engineering."Includes bibliographical referencesA review of the author's internship experience with CH���M HILL, Inc.
during the period September 1975 through May 1976 is presented. During this nine month
internship the author worked as an Engineer II in the Industrial Processes discipline of this
large consulting engineering firm... The author's prime responsibility was as one of three
lead design engineers on the design of a large wastewater treatment facility for a pulp mill
in Hoquiam, Washington owned by ITT Rayonier Inc. The work generally consisted of the design
of individual treatment units and associated piping and pumping. The purpose of the project
was to provide wastewater treatment capabilities that would satisfy the effluent limitations
(standards) imposed upon the mill by the State of Washington Department of Ecology and the
U.S. Environmental Protection Agency. The author's assignment also entailed necessary
interaction with the project manager and other CH���M HILL design engineers and support staff
members, the client's representatives, and representatives of two other consulting engineering
firms working on the project. Thus, the internship position at CH���M HILL provided considerable
experience coordinating the author's work with the work of other engineers, guiding the design
and administrative efforts of a support staff, and interacting regularly with the client and
other consulting firms. This broad exposure to a variety of engineering and organizational
problems provided a valuable educational experience
