The document discusses element birth and death in multiphysics simulations. It describes how elements can be deactivated and reactivated to model effects like material removal or addition over time. Elements are deactivated by reducing their stiffness rather than removing them. Birth and death can be used to model phenomena like phase changes, failure propagation, and layered fabrication processes. Commands are provided to control element activation based on calculated results like temperature.

Recipes 9 of Data Warehouse and Business Intelligence - Techniques to control...Massimo Cenci
In the loading of a Data Warehouse is important to have full control of the processing units that compose it.
Each processing unit must be carefully monitored both in the detection of errors that may occur,
both in the analysis of the execution times
OverviewUsing the C-struct feature, design, implement and .docxalfred4lewis58146
Overview
Using the C-struct feature, design, implement and test a new (programmer-defined) data type that can be used to represent and manipulate a collection of sorted integers. Such a data type can be used, for instance, by an instructor to process test scores (assuming test scores are recorded as integral values); each instance (object) of the data type would be able to represent a group of related test scores in that case. The operations supported should include the following:
Checking to see if the collection is empty.
NOTE: A collection is empty if it doesn't contain any values.
Finding the number of values in the collection.
Adding a new value to the collection.
NOTE:
You should NOT simply append the new item to the end of the array and then use a sorting algorithm of some kind to sort the array. You also should NOT use any temporary arrays to perfom the insertion.
TIP:
Adopt/adapt the StoreOrdered function of Assignment 4.
Finding the collection's lowest/highest value.
NOTE:
The lowest/highest value is undefined if the collection is empty.
Finding the value at a given position in the collection, with position starting at 1 (i.e., array index 0 corresponds to position 1, array index 1 corresponds to position 2, and so on).
NOTE:
A positional value is undefined if the collection is empty.
Finding the collection's average.
NOTE:
The average is undefined if the collection is empty.
Removing an occurrence (if exists) of a specified value from the collection.
Finding the number of occurences of a specified value in the collection.
Resetting the collection to an empty collection.
Adding a given collection into another collection.
NOTE:
The given collection (addend) and the collection to be added to (benend) may be the same collection before the operation takes place (in which case the operation will result in "each of the items in the original collection is duplicated exactly once").
TIP:
The "adding a new value to collection" function (assuming implemented correctly) should prove useful here.
Combining two given collections into a third one (which is a new collection to be returned).
TIP:
The "adding a new value to collection" function (assuming implemented correctly) should prove useful here.
Testing to see if two given collections are identical.
NOTE:
Two collections are identical if they contain the same number of items and the values contained in every corresponding pair of items are equal.
Some Specifics
You will use a fixed-sized, compile-time array (and other supporting data members) to implement the new data type that can be used to declare variables (objects) each of which can represent a collection of up to MAX_SIZE integers. For the purpose of testing, set MAX_SISE to 10; your design and implementation of the data type, however, should enable the maximum size to be easily modified, i.e., only need to change the value that MAX_SIZE is set to.

# Overview of Oracle Database Fundamentals
## Introduction to Oracle, Triggers, and Wrapping
Oracle Database is a powerful and widely used relational database management system (RDBMS). It provides a robust platform for managing large volumes of data efficiently. Key features of Oracle include its ability to handle complex queries, support for multi-user environments, and a comprehensive suite of security measures.
**Triggers** are procedural code executed automatically in response to certain events on a particular table or view in a database. They are essential for maintaining data integrity and enforcing business rules. **Wrapping** in Oracle refers to the process of encoding PL/SQL source code to protect it from unauthorized viewing and tampering.
## Functions/Responsibilities of a DBA
A Database Administrator (DBA) is responsible for the overall management and maintenance of a database system. Key responsibilities include:
- **Installation and Configuration**: Setting up Oracle databases, including installing the software and configuring database instances.
- **Performance Monitoring**: Continuously monitoring database performance to ensure optimal operation and identifying potential issues.
- **Backup and Recovery**: Implementing and managing backup procedures to protect data against loss and ensuring the ability to recover data in case of hardware failures or other disasters.
- **Security Management**: Ensuring that the database is secure from unauthorized access by managing user permissions and roles.
- **Troubleshooting**: Diagnosing and resolving database issues, including performance bottlenecks, connectivity problems, and data corruption.
## Oracle Product Details
Oracle offers a range of products and editions to meet different needs, from small applications to large enterprise systems. Key products include:
- **Oracle Database Standard Edition**: Suitable for small to medium-sized businesses, offering essential database features at a lower cost.
- **Oracle Database Enterprise Edition**: Provides advanced features, including high availability, performance optimization, and security enhancements, ideal for large enterprises.
- **Oracle Cloud**: Oracle's cloud services, including Autonomous Database, which offers self-driving, self-securing, and self-repairing capabilities.
## Oracle Files, System, and User Processes
Oracle database architecture consists of several key components:
- **Control Files**: These files contain metadata about the database structure, including the database name, timestamps, and pointers to data files and redo log files.
- **Data Files**: Store the actual data within the database.
- **Redo Log Files**: Record all changes made to the data, enabling recovery in case of a failure.
- **System Processes**: Manage tasks such as memory allocation, I/O operations, and process scheduling.
- **User Processes**: Handle interactions between the user applications and the database.

Hands-on-OpenIPSL.org using OpenModelica!
Instructor:
Luigi Vanfretti, PhD - RPI
luigi.vanfretti@gmail.com
Abstract:
The Modelica language, being standardized and equation-based, has proven valuable for the for model exchange, simulation and even for model validation applications in actual power systems. These important features have been now recognized by the European Network of Transmission System Operators, which have adopted the Modelica language for dynamic model exchange in the Common Grid Model Exchange Standard (v2.5, Annex F).
Following previous FP7 project results, within the ITEA 3 openCPS project, the presenters have continued the efforts of using the Modelica language for power system modeling and simulation, by developing and maintaining the OpenIPSL library: http://openipsl.org
This tutorial will follow the seminar introducing OpenIPSL.org and give you hands-on-experience on using the library using the OpenModelica modeling and simulation environment.
It is assumed that you have very little experience with OpenModelica and the Modelica language, so detailed instructions are provided.
You will need to bring your computer with OpenModelica installed, see the following link for a .pdf information on installation: https://goo.gl/oLAFv4
You will be working with three examples. In the first example, you will work setting up a power system from scratch and performing simulations using OpenModelica and the OpenIPSL. The second example consists on performing linear analysis using OMNotebook, and implementing a power system stabilizer for the model of example one. Finally, in the third example, you will perform simulations of a typical IEEE 9-Bus power systems and perform a simple analysis of results.

GDG Cloud Southlake #33: Boule & Rebala: Effective AppSec in SDLC using Deplo...James Anderson
Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle.
Gopinath Rebala
Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery. Gopi also has a strong connection with our customers, leading design and architecture for strategic implementations. Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

9. In some circumstances, an element's birth and death status depend upon an ANSYS-calculated quantity, such as temperature, stress, strain, etc. You can issue commands such as ETABLE and ESEL to determine the value of such quantities in selected elements, and to change the status (melted, solidified, ruptured, etc.) of those elements accordingly. This capability is useful for modeling effects due to phase changes (as in welding processes, when structurally inactive molten material solidifies and becomes structurally active), failure-surface propagation, and other analysis-dependent element changes. 13.2. Understanding Element Birth and Death To achieve the "element death" effect, the ANSYS program does not actually remove "killed" elements. Instead, it deactivates them by multiplying their stiffness (or conductivity, or other analogous quantity) by a severe reduction factor ( ESTIF ). This factor is set to 1.0E-6 by default, but can be given other values. (For more information, see Apply Loads and Obtain the Solution .) Element loads associated with deactivated elements are zeroed out of the load vector, however, they still appear in element-load lists. Similarly, mass, damping, specific heat, and other such effects are set to zero for deactivated elements. The mass and energy of deactivated elements are not included in the summations over the model. An element's strain is also set to zero as soon as that element is killed. In like manner, when elements are "born," they are not actually added to the model; they are simply reactivated . You must create all elements, including those to be born in later stages of your analysis, while in PREP7. You cannot create new elements in SOLUTION. To "add" an element, you first deactivate it, then reactivate it at the proper load step.
10. I When an element is reactivated, its stiffness, mass, element loads, etc. return to their full original values. Elements are reactivated with no record of strain history (or heat storage, etc.); however, initial strain defined as a real constant (for elements such as LINK1 ) will not be affected by birth and death operations. Unless large-deformation effects are activated ( NLGEOM ,ON), some element types will be reactivated in their originally specified geometric configuration. (Large-deformation effects should be included to obtain meaningful results.) Thermal strains are computed for newly-activated elements based on the current load step temperature and the reference temperature. Thus, newborn elements with thermal loads may not be stress-free as intended. The material property REFT can be used instead of the global TREF to specify material-dependent reference temperatures, allowing you to specify the activation temperature as a stress-free temperature.
11. I 3.4. Employing Birth and Death You can apply element birth and death behavior to most static and nonlinear transient analyses using the same basic procedures described in the various analysis guides. Modify your basic analysis procedure as follows to incorporate the element birth and death feature: 13.4.1. Build the Model While in /PREP7 , create all elements - even those that will not be activated until later load steps. You cannot create new elements outside of /PREP7 . 13.4.2. Apply Loads and Obtain the Solution For all analyses employing element birth and death, perform the following actions in the solution ( SOLU ) phase:
12. 13.4.2.1. Define the First Load Step In the first load step, you must choose the analysis type and all appropriate analysis options via the ANTYPE command. For a structural analysis, activate large-deflection effects via the NLGEOM ,ON command. For all birth and death applications, set the Newton-Raphson option to full explicitly in the first load step via the NROPT command. (The ANSYS program cannot predict the presence of an EKILL command in a subsequent load step.) Deactivate ( EKILL ) all of the initially inactive elements that you intend to add (reactivate) in later load steps. Elements are deactivated (or activated) in the first substep of the load step, and maintain that status through the rest of the load step. The default reduction factor used as a stiffness multiplier might not suffice for some problems; sometimes, you may need to use a more severe reduction factor. To provide a new value for the reduction factor, issue the ESTIF command. Nodes not connected to any active elements may "float," or pick up stray degree-of-freedom (DOF) responses. You may want to constrain inactive DOFs ( D , CP , etc.) in some cases to reduce the number of equations to be solved and to avoid ill-conditioning. Constraining inactive DOFs can become more important for cases in which you want to reactivate elements with a specific shape (or temperature, etc.). If so, remove the artificial constraints when you reactivate elements, and remove nodal loads from inactive DOFs (that is, at nodes not connected to any active elements). Similarly, you must specifically add nodal loads (if any) to reactivated DOFs.

14. 1 3.4.2.2. Define Subsequent Load Steps In the remaining load steps, you can deactivate and reactivate elements as desired. As before, be sure to apply and delete constraints and nodal loads as appropriate. To deactivate and reactivate elements, issue the EKILL and EALIVE commands, respectively. 13.4.2.2.1. Sample Input for Subsequent Load Steps The following simplified input listing demonstrates how you might deactivate and reactivate elements: ! Second (or subsequent) load step: TIME,... ESEL,...

Adds nodal loads as appropriate to active DOFs DDELE,... ! Deletes constraints from reactivated DOFs SAVE SOLVE
15. 13.4.3. Review the Results Typically, you will follow standard procedures when postprocessing an analysis containing deactivated or reactivated elements. Be aware that "killed" elements are still present in your model, even though they make an insignificant contribution to the stiffness (conductivity, etc.) matrix; therefore, they are included in element displays, output listings, etc. For example, deactivated elements are included in nodal results averaging (via the PLNSOL command) and will "smear" the results. Ignore the entire element printout for deactivated elements because many items computed make little physical sense. To remove deactivated elements for element displays and other postprocessing operations, issue the ESEL command.
16. 13.4.4. Use ANSYS Results to Control Birth and Death At times, you will not explicitly know the location of elements that you need to deactivate or reactivate. For example, if you want to "kill" melted elements in a thermal analysis (that is, to model the removal of melted material), you will not know the location of those elements beforehand; you will need to identify them on the basis of their ANSYS-calculated temperatures. When the decision to deactivate or reactivate an element depends on the value of an ANSYS result item (such as temperature, stress, strain, etc.), you can use commands to identify and select the critical elements. To identify the critical elements, issue the ETABLE command. To select the critical elements, issue the ESEL command. You could then deactivate or reactivate the selected elements. To deactivate the selected elements, issue the EKILL ,ALL command. To reactivate the selected elements, issue the EALIVE ,ALL command. Note You could also use the ANSYS Parametric Design Language to write a macro to perform such an operation. See the ANSYS Parametric Design Language Guide for more information.
