biomedical_machine_learning_poster_48''x36''
This document summarizes a project to develop a statistical model for biomedical text mining using machine learning algorithms. The project uses a Hidden Markov Model trained with the Baum-Welch algorithm to identify biological entities in literature. It clusters seven entities from GENIA corpus abstracts and aligns them to PubMed abstracts to generate probability matrices. Various machine learning classifiers like kNN, Naive Bayes, and SVM are also implemented and evaluated on the task. The work is supported by grants from NIH.
check sheet
A check sheet is a structured form for collecting and analyzing repeated observational data. It involves defining the event or problem to be observed, determining the data collection period, designing a simple form for recording data with checkmarks or symbols, labeling the form, testing the form, and recording data each time the event occurs. Check sheets are well-suited for collecting frequency data on events, problems, defects and their causes in production processes.
Aggregate fact tables
Aggregates are precalculated summaries derived from fact tables at the lowest level of granularity, where facts are captured at the most detailed level possible from operational systems. Choosing a star schema with a fact table at the lowest grain has advantages, as it allows producing large result sets from a simple structure with dimension tables connected to a most granular fact table reflecting single orders, invoices, and products from operational systems. This requires aggregating the fact table to address the large size and need for aggregated views of the data.
Agreggates i
The document discusses strategies for improving data warehouse performance through the use of aggregate tables. It describes how aggregate tables summarize fact data across dimension attributes to reduce the number of rows that must be accessed by queries. The key points covered include: defining potential aggregate tables based on fact and dimension grains; identifying aggregates that can benefit common queries and drill-across reports; and assessing aggregates based on the number of rows summarized and potential user benefits to optimize performance gains.
Belajar spss
The document appears to be analyzing crosstabulation output from SPSS comparing two variables: persalinan (type of delivery) and senam_hamil (whether prenatal exercise was regular or irregular). It finds that there is no significant association between these two variables based on a chi-square test (p=0.266).
Dax Power Pivot: Introductory Level
The document discusses PowerPivot in Excel and its usefulness for supply chain analytics. PowerPivot allows Excel to have the functionality of a relational database by adding a PowerPivot tab. It can link multiple tables together more easily than vlookup, and can link to different database types. PowerPivot is useful for supply chain analytics because supply chain data often involves transaction files that reference multiple tables. The components of PowerPivot include the PowerPivot tab interface and the data model interface. PowerPivot can also connect to other large datasets.

Webinar: From Relational Databases to MongoDB - What You Need to Know
Relational databases weren't designed to cope with the scale and agility challenges that face modern applications. MongoDB can offer scalability, performance and ease of use - but proper design will be a critical factor to that success. We'll take a dive into how MongoDB works to better understand what non-relational design is, why we might use it and what advantages it gives us. We'll develop schema designs by example, and consider strategies for scale out.
A Primer for Relational Database Design and Use
This document provides an overview of Microsoft Access and how to design databases and applications using its features. It discusses what Access is, when to use Access over Excel or SPSS, and how to create tables, queries, forms and reports. The key aspects covered include basic database design principles, creating relationships between tables, using queries to select, calculate, group and export data, and building a graphical user interface with forms and reports. Resources for learning more about Access are also provided.

Когда задают вопрос: "Что такое хороший дизайн базы данных?", - первое что всплывает в голове - нормализация и правила, которые нам рассказывали ещё в институте. Но почему-то всё чаще мы слышим что нормализация это зло, сейчас диски и память дешёвые, и в принципе лучше иметь денормализированную схему.
Но так ли это?
В этом мы и разберёмся в ходе доклада, посмотрев реальные примеры, преимущества и недостатки как нормализации, так и денормализации.
Database Systems - Normalization of Relations(Chapter 4/3)
The document discusses normalization, which is a process for relational database design that reduces data redundancy and improves data integrity. It involves decomposing relations to eliminate anomalies like insertion, deletion, and modification anomalies. Several normal forms are described - 1NF, 2NF, 3NF, BCNF, 4NF, and 5NF - each addressing different types of dependencies and anomalies. The goal of normalization is to organize the data in a logical manner and break relations into smaller, less redundant relations without affecting the information contained.
Force.com Data Modeling: The Advantages of Denormalization
Your data model choices impact analytics, performance, security, user experience, and coding requirements. While it might seem counterintuitive, the key to successful Force.com data model design is a pattern of denormalization, with tightly coupled attributes that describe core entities, rather than the traditional pattern of normalization. Join us as we explore the pros and cons of these design patterns.
Hierarchical Denormalization
This document discusses hierarchical de-normalization and its effects on database performance. It introduces normalization and de-normalization as common processes in database design. The methodology section describes comparing the efficiency of de-normalized and normalized data models using a set of single-dimensional and multi-dimensional queries. The conclusion is that hierarchical de-normalization likely improves query performance by reducing response times for queries involving multiple joins in a data warehouse.

3. The goal is to provide an alternative educational approach to teaching database normalization that is more practical and helps improve students' understanding compared to traditional theoretical explanations.
Eav Data Model Concepts
This presentation covers EAV type of data modeling. We would check various aspects of data modeling and compare them with different types of data modeling. Basically this relates to a type of data modeling in database.
Databases: Denormalisation
Denormalization involves deliberately relaxing normalization rules to introduce redundancy into a database design in order to improve performance when a fully normalized system is unable to meet performance requirements. It may involve combining relations so they remain normalized but contain null values, or leaving relations in second normal form instead of moving to third normal form. While denormalization can speed up retrievals, it often sacrifices flexibility and slows down updates, making implementation more complex. Normalization is still important, but denormalization may be used after considering performance needs versus these tradeoffs.

Study start up activities in clinical data management
Study start-up (SSU) is so much more than a one-time document management exercise. It’s a global, strategic operation that can get new drugs approved faster – and it’s ripe for innovation – from Site Selection to Site Activation and Site Training.
Many SSU tech solutions deployed by sponsors don’t deliver the results promised because they add burden without benefits to clinical research sites. The result? Site staff simply avoid using them.
When that happens, document exchange and tracking falls back to paper, email and Excel formats – with CRAs holding the processes together.

How to achieve better time management in EDC start up
Clinical data management requires strict time management processes, especially in study start up within an electronic data capture (EDC) system. Three steps that clinical data management teams can take to outline the planning and executing of each task that needs to be considered are as follows:
Make a List: Create a daily or weekly task list and schedule when each task will be completed. This strategy will assist you in maintaining focus and staying organized.
Set realist goals: Be realistic about what you can finish in the amount of time you have. When setting unrealistic goals, failure is almost certain to follow.
Explore time-saving techniques: Examples of techniques that could help save time include grouping similar tasks together or using a timer to stay focused.
To help get started, here is a list of EDC considerations for Study Start-Up deadlines:
Protocol finalization and study enrollment
Split go-live considerations
eCRF Specification meetings (this will ensure proper collaboration and minimize any back-and-forth communication)
EDC add-on modules (which will be required and need validation?)

Static Load Balancing of Parallel Mining Efficient Algorithm with PBEC in Fre...
This document presents a proposed static load balancing method for parallel mining of frequent sequences. It partitions the set of all frequent sequences into disjoint prefix-based equivalence classes (PBECs). It estimates the relative execution time of each PBEC using the sequential PrefixSpan algorithm on sampling data sets. The PBECs are then assigned to processors based on these estimated execution times to balance the computational load. The goal is to develop an efficient parallel frequent sequence mining algorithm that can scale to large datasets through static load balancing of computations across multiple processors.

Mining useful information and helpful knowledge from large databases has evolved into
an important research area in recent years. Among the classes of knowledge derived, finding
sequential patterns in temporal transaction databases is very important since it can help model
customer behavior. In the past, researchers usually assumed databases were static to simplify datamining problems. In real-world applications, new transactions may be added into databases
frequently. Designing an efficient and effective mining algorithm that can maintain sequential
patterns as a database grows is thus important. In this paper, we propose a novel incremental mining
algorithm for maintaining sequential patterns based on the concept of pre-large sequences to reduce
the need for rescanning original databases.

ABSTRACT
A data warehouse provides information for analytical processing,
decision making and data mining tools. As the concept of real-
time enterprise evolves, the synchronism between transactional
data and data warehouses, statically implemented, has been
redefined. Traditional data warehouse systems have static
structures of their schemas and relationships between data, and
therefore are not able to support any dynamics in their structure
and content. Their data is only periodically updated because they
are not prepared for continuous data integration. For real-time
enterprises with needs in decision support purposes, real-time data
warehouses seem to be very promising. In this paper we present a
methodology on how to adapt data warehouse schemas and user-
end OLAP queries for efficiently supporting real-time data
integration. To accomplish this, we use techniques such as table
structure replication and query predicate restrictions for selecting
data, to enable continuously loading data in the data warehouse
with minimum impact in query execution time. We demonstrate
the efficiency of the method by analyzing its impact in query
performance using benchmark TPC-H executing query workloads
while simultaneously performing continuous data integration at
various insertion time rates.
Keywords
real-time and active data warehousing, continuous data
integration for data warehousing, data warehouse refreshment
loading process.
1. INTRODUCTION
A data warehouse (DW) provides information for analytical
processing, decision making and data mining tools. A DW
collects data from multiple heterogeneous operational source
systems (OLTP – On-Line Transaction Processing) and stores
summarized integrated business data in a central repository used
by analytical applications (OLAP – On-Line Analytical
Processing) with different user requirements. The data area of a
data warehouse usually stores the complete history of a business.
The common process for obtaining decision making information
is based on using OLAP tools [7]. These tools have their data
source based on the DW data area, in which records are updated
by ETL (Extraction, Transformation and Loading) tools. The ETL
processes are responsible for identifying and extracting the
relevant data from the OLTP source systems, customizing and
integrating this data into a common format, cleaning the data and
conforming it into an adequate integrated format for updating the
data area of the DW and, finally, loading the final formatted data
into its database.
Traditionally, it has been well accepted that data warehouse
databases a ...
The graphical analysis for maintenace management method
This article proposes a new graphical tool called the Graphical Analysis for Maintenance Management (GAMM) method to support maintenance management decision making. The GAMM method visualizes equipment dependability data like the number and duration of corrective and preventive interventions over time. It helps identify opportunities to improve operations and maintenance by analyzing patterns in the timing and impacts of interventions. The GAMM method estimates reliability using nonparametric estimators and graphs cumulative intervention rates over time based on historical maintenance data.

IRJET- Disease Prediction System
This document describes a disease prediction system that uses machine learning algorithms like decision trees, random forests and naive Bayes to predict a disease based on symptoms provided by a patient. The researchers developed a logistic regression model to take in symptoms and predict the likely disease. It was created using Python and aims to help busy professionals more easily identify health issues before they become serious. The system was built using techniques like data collection, preprocessing, model training/evaluation and aims to improve performance over iterations. It was found to provide time savings and early disease warnings compared to traditional diagnosis methods.

Elimination of data redundancy before persisting into dbms using svm classification,
Data Base Management System is one of the
growing fields in computing world. Grid computing, internet
sharing, distributed computing, parallel processing and cloud
are the areas store their huge amount of data in a DBMS to
maintain the structure of the data. Memory management is
one of the major portions in DBMS due to edit, delete, recover
and commit operations used on the records. To improve the
memory utilization efficiently, the redundant data should be
eliminated accurately. In this paper, the redundant data is
fetched by the Quick Search Bad Character (QSBC) function
and intimate to the DB admin to remove the redundancy.
QSBC function compares the entire data with patterns taken
from index table created for all the data persisted in the
DBMS to easy comparison of redundant (duplicate) data in
the database. This experiment in examined in SQL server
software on a university student database and performance is
evaluated in terms of time and accuracy. The database is
having 15000 students data involved in various activities.
Keywords—Data redundancy, Data Base Management System,
Support Vector Machine, Data Duplicate.
I. INTRODUCTION
The growing (prenominal) mass of information
present in digital media has become a resistive problem for
data administrators. Usually, shaped on data congregate
from distinct origin, data repositories such as those used by
digital libraries and e-commerce agent based records with
disparate schemata and structures. Also problems regarding
to low response time, availability, security and quality
assurance become more troublesome to manage as the
amount of data grow larger. It is practicable to specimen
that the peculiarity of the data that an association uses in its
systems is relative to its efficiency for offering beneficial
services to their users. In this environment, the
determination of maintenance repositories with “dirty” data
(i.e., with replicas, identification errors, equal patterns,
etc.) goes greatly beyond technical discussion such as the
everywhere quickness or accomplishment of data
administration systems.

Pivoting approach-eav-data-dinu-2006
The document describes and benchmarks three approaches for extracting Entity-Attribute-Value (EAV) data from clinical databases into a tabular format:
1. Using full outer joins, which performed poorly for larger numbers of attributes, especially in Oracle.
2. Using left outer joins, which scaled better in Oracle but had exponential growth in execution time in SQL Server.
3. Using hash tables and memory to perform the equivalent of multiple joins, which had the best and most linear performance across databases tested.
Modifying this approach to retrieve all attribute values up front removed irregular performance in SQL Server 2000 but increased execution times for smaller numbers of attributes in other databases.
Demand Value Identification using Improved Vector Analysis
This document summarizes a research paper that uses machine learning techniques like support vector regression and optimization algorithms like particle swarm optimization and artificial bee colony to improve demand forecasting in supply chain management. It begins with an abstract that outlines using SVR with PSO and ABC to optimize parameters and minimize inventory and transportation costs. It then reviews relevant literature on support vector machines, support vector regression, using PSO and ABC with SVR, and the artificial bee colony algorithm. The objectives are defined as optimizing inventory costs through improved information sharing in the supply chain. The full paper would apply these techniques to a case study and compare results.

IRJET- A Review of Data Cleaning and its Current Approaches
This document summarizes various approaches to data cleaning. It begins by stating that data cleaning is an important preprocessing step in data mining to detect and remove corrupted, inaccurate, or inconsistent data. It then reviews several common data cleaning techniques, including constraint-based data repairing, statistical methods, interactive approaches, Hadoop-based distributed cleaning, and clustering-based outlier detection. The document concludes that the appropriate cleaning approach depends on the type of data but the overall goal is to improve data quality and accuracy for downstream analysis and mining.
ICIC 2014 Tracking of the Mode of Action Landscape in Breast Cancer using Rep...
Assessment of the “Mode of Action Landscape” for particular disease areas is of high interest for pharmaceutical companies. To enable identification of upcoming, established and vanishing modes of action over time and clinical phases it is crucial to have tools for integration and comparison of drug pipeline data from various sources, including informative visualizations of changes in the landscape.
The BizInt Smart Charts product family including VantagePoint - Smart Charts Edition (VP-SCE) enables these analyses and was therefore selected for evaluation. Data was integrated from different key drug pipeline databases, and the newly developed VP-SCE provided opportunities to use in-house data for normalization of important field content such as the highly diverse lists of “Mode of Action” generated by the pipeline databases. Using an example of pipeline data in the field of breast cancer we will show how the data was curated and processed to reach the final landscape, and how the programs can be applied in the most effective way. Examples of visualizations for facilitated decision-making will also be shown. To this end, our presentation will provide insight on the value of integrating and visualizing both external and internal data from drug pipelines employing these tools.
Enhancement techniques for data warehouse staging area
This document discusses techniques for enhancing the performance of data warehouse staging areas. It proposes two algorithms: 1) A semantics-based extraction algorithm that reduces extraction time by pruning useless data using semantic information. 2) A semantics-based transformation algorithm that similarly aims to reduce transformation time. It also explores three scheduling techniques (FIFO, minimum cost, round robin) for loading data into the data warehouse and experimentally evaluates their performance. The goal is to enhance each stage of the ETL process to maximize overall performance.
Integrated quality management system
MasterControl's integrated quality management software system centralizes and integrates quality processes like CAPA, deviations, and complaint handling. This allows companies to effectively monitor and comply with regulations while improving quality enterprise-wide. The software automates and streamlines document control, change control, training control, audits, and other quality processes. Hundreds of companies use MasterControl's configurable system to facilitate compliance with FDA and ISO standards.
IRJET- Comparative Study of ETL and E-LT in Data Warehousing
This document compares the Extract, Transform, Load (ETL) approach and the Extract, Load, Transform (ELT) approach for loading data into a data warehouse. It discusses how ETL works by extracting data from various sources, transforming it using business rules, and loading it into the data warehouse. ELT instead extracts and loads the raw data first before transforming it. The document reviews past research on both approaches and discusses their advantages and disadvantages. It aims to evaluate the performance differences between ETL and ELT.
Earned Value Management Meets Big Data
The Earned Value Management System (EVMS) maintains period–by–period data in its underlying databases. The contents of the Earned Value repository can be considered BIG DATA, characterized by three attributes – 1) Volume: Large amounts of data; 2) Variety: data comes from different sources, including traditional data bases, documents, and complex records; 3) Velocity: the content is continually being updated by absorbing other data collections, through previously archived data, and through streamed data from external sources.
With this time series information in the repository, analysis of trends, cost and schedule forecasts, and confidence levels of these performance estimates can be calculated using statistical analysis techniques enabled by the Autoregressive Integrated Moving Average (ARIMA) algorithm provided by the R programming system. ARIMA provides a statistically informed Estimate At Completion (EAC) and Estimate to Complete (ETC) to the program in ways not available using standard EVM calculations. Using ARIMA reveals underlying trends not available through standard EVM reporting calculations.
With ARIMA in place and additional data from risk, technical performance and the Work Breakdown Structure, Principal Component Analysis can be used to identify the drivers of unanticipated EAC.

The CBC machine is a common diagnostic tool used by doctors to measure a patient's red blood cell count, white blood cell count and platelet count. The machine uses a small sample of the patient's blood, which is then placed into special tubes and analyzed. The results of the analysis are then displayed on a screen for the doctor to review. The CBC machine is an important tool for diagnosing various conditions, such as anemia, infection and leukemia. It can also help to monitor a patient's response to treatment.
Electric vehicle and photovoltaic advanced roles in enhancing the financial p...
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

Medical image analysis has witnessed significant advancements with deep learning techniques. In the domain of brain tumor segmentation, the ability to
precisely delineate tumor boundaries from magnetic resonance imaging (MRI)
scans holds profound implications for diagnosis. This study presents an ensemble convolutional neural network (CNN) with transfer learning, integrating
the state-of-the-art Deeplabv3+ architecture with the ResNet18 backbone. The
model is rigorously trained and evaluated, exhibiting remarkable performance
metrics, including an impressive global accuracy of 99.286%, a high-class accuracy of 82.191%, a mean intersection over union (IoU) of 79.900%, a weighted
IoU of 98.620%, and a Boundary F1 (BF) score of 83.303%. Notably, a detailed comparative analysis with existing methods showcases the superiority of
our proposed model. These findings underscore the model’s competence in precise brain tumor localization, underscoring its potential to revolutionize medical
image analysis and enhance healthcare outcomes. This research paves the way
for future exploration and optimization of advanced CNN models in medical
imaging, emphasizing addressing false positives and resource efficiency.
Comparative analysis between traditional aquaponics and reconstructed aquapon...
The aquaponic system of planting is a method that does not require soil usage. It is a method that only needs water, fish, lava rocks (a substitute for soil), and plants. Aquaponic systems are sustainable and environmentally friendly. Its use not only helps to plant in small spaces but also helps reduce artificial chemical use and minimizes excess water use, as aquaponics consumes 90% less water than soil-based gardening. The study applied a descriptive and experimental design to assess and compare conventional and reconstructed aquaponic methods for reproducing tomatoes. The researchers created an observation checklist to determine the significant factors of the study. The study aims to determine the significant difference between traditional aquaponics and reconstructed aquaponics systems propagating tomatoes in terms of height, weight, girth, and number of fruits. The reconstructed aquaponics system’s higher growth yield results in a much more nourished crop than the traditional aquaponics system. It is superior in its number of fruits, height, weight, and girth measurement. Moreover, the reconstructed aquaponics system is proven to eliminate all the hindrances present in the traditional aquaponics system, which are overcrowding of fish, algae growth, pest problems, contaminated water, and dead fish.

Optimizing Gradle Builds - Gradle DPE Tour Berlin 2024
Sinan from the Delivery Hero mobile infrastructure engineering team shares a deep dive into performance acceleration with Gradle build cache optimizations. Sinan shares their journey into solving complex build-cache problems that affect Gradle builds. By understanding the challenges and solutions found in our journey, we aim to demonstrate the possibilities for faster builds. The case study reveals how overlapping outputs and cache misconfigurations led to significant increases in build times, especially as the project scaled up with numerous modules using Paparazzi tests. The journey from diagnosing to defeating cache issues offers invaluable lessons on maintaining cache integrity without sacrificing functionality.

EFFICIENT EXECUTION METHODS OF PIVOTING FOR BULK EXTRACTION OF ENTITY-ATTRIBUTE-VALUE-MODELED DATA
- 1. EFFICIENT EXECUTION METHODS OF PIVOTING FOR BULK EXTRACTION OF ENTITY-ATTRIBUTE-VALUE-MODELED DATA ABSTRACT Entity-Attribute-Value (EAV) tables are widely used to store data in electronic medical records and clinical study data management systems. Before they can be used by various analytical (e.g., data mining and machine learning) programs, EAV-modeled data usually must be transformed into conventional relational table format through pivot operations. This time- consuming and resource-intensive process is often performed repeatedly on a regular basis, e.g., to provide a daily refresh of the content in a clinical data warehouse. Thus, it would be beneficial to make pivot operations as efficient as possible. In this paper, we present three techniques for improving the efficiency of pivot operations: (1) filtering out EAV tuples related to unneeded clinical parameters early on, (2) supporting pivoting across multiple EAV tables, and (3) conducting multi-query optimization. We demonstrate the effectiveness of our techniques through implementation. We show that our optimized execution method of pivoting using these techniques significantly outperforms the current basic execution method of pivoting. Our techniques can be used to build a data extraction tool to simplify the specification of and improve the efficiency of extracting data from the EAV tables in electronic medical records and clinical study data management systems.
