CFRP STRENGTHENING OF CIRCULAR CONCRETE SLAB WITH AND WITHOUT OPENINGSIAEME Publication
This paper includes an investigation and experimental testing of R.C circular slabs with and without opening and strengthens with CFRP sheets, CFRP bare, and both. Normal concrete (NC) and self-compacted concrete (SCC) were used to cast the slabs. The experimental part includes testing of fourteen circular slabs divided into four groups having diameter of 1200mm and thickness of 80mm. Three types of strengthening used; the first type is CFRP sheets only, the second type is CFRP bar only, and the third type is the combination of the two types of strengthening (i.e. CFRP sheets and CFRP bar together). The use of CFRP sheets delays the appearance of the cracks by (14.75%-51.76%) compared with slabs without strengthening. The experimental results showed that the opening existence in the slabs without strengthening reduces the ultimate load carrying capacity by (24.98%-27.77%) compared with slab without opening, and the higher reduction in the ultimate load occurs in the slab (S2S2) by (30.55%) which is strengthen with CFRP sheets and contains two square opening.

Speaker: João Miranda
Language: English
OutSystems Platform is a product for rapid application delivery of desktop and mobile web applications. As part of the product, we offer performance instrumentation, monitoring and troubleshoot capabilities for the generated applications. The goal is to offer a zero-friction experience when troubleshooting desktop and mobile web performance problems, without requiring any special instrumentation effort when building the application. This talk will cover how we achieve that goal and how the approach can be applied to other projects. We have to decide which metrics to gather, how to gather them and mash it all up in out-of-the-box dashboards. All the while, we want our clients to be able to use the raw instrumentation data so they can integrate it with their own application performance monitoring solutions.

1.Review news reports from a specific data breach. Choose a breach f.pdfarihantpatna
1.Review news reports from a specific data breach. Choose a breach for which plausable news
reports have identified how the attack occured and have identified the likely attacker. Complete
the following reports.
a. write a thrat agent profile of the likely attacker
b. write an attack scenario for the data breach.
c. write an attack case study about the data breack.
2.based on your answer to tha question above, develop an authentication policy for Alice,
asuming she faces weak authentication threats at home.
3. Review news reports for cyber attacks. identify a cyber attack that relied on masquerade to
succeed. Write an attack case study about that attack. Be sure to explain how the masquerade
was supposed to work and whether or not it succeeded.
Solution
The Attack Surface describes all of the different points where an attacker could get into a system,
and where they could get data out.
The Attack Surface of an application is:
You overlay this model with the different types of users - roles, privilege levels - that can access
the system (whether authorized or not). Complexity increases with the number of different types
of users. But it is important to focus especially on the two extremes: unauthenticated, anonymous
users and highly privileged admin users (e.g. database administrators, system administrators).
Group each type of attack point into buckets based on risk (external-facing or internal-facing),
purpose, implementation, design and technology. You can then count the number of attack points
of each type, then choose some cases for each type, and focus your review/assessment on those
cases.
With this approach, you don\'t need to understand every endpoint in order to understand the
Attack Surface and the potential risk profile of a system. Instead, you can count the different
general type of endpoints and the number of points of each type. With this you can budget what
it will take to assess risk at scale, and you can tell when the risk profile of an application has
significantly changed.
Identifying and Mapping the Attack Surface
You can start building a baseline description of the Attack Surface in a picture and notes. Spend
a few hours reviewing design and architecture documents from an attacker\'s perspective. Read
through the source code and identify different points of entry/exit:
The total number of different attack points can easily add up into the thousands or more. To
make this manageable, break the model into different types based on function, design and
technology:
You also need to identify the valuable data (e.g. confidential, sensitive, regulated) in the
application, by interviewing developers and users of the system, and again by reviewing the
source code.
You can also build up a picture of the Attack Surface by scanning the application. For web apps
you can use a tool like the OWASP_Zed_Attack_Proxy_Project or Arachnior Skipfish or w3af
or one of the many commercial dynamic testing and vulnerability scanning tools or servi.
Performance is the most important attribute for success of any commercial and Enterprise Software. In a client server environment, developers focus a lot on optimizing the Data and Logical Tiers. Optimization of Presentation Tier which is responsible for more than 30 % of performance is usually ignored.
The document is developed with the intension to teach the technical staff on Optimizing the Presentation Tier which significantly improves the performance of the Client Server applications.
Measure anything, measure everything.
Effortless monitoring with Statsd, Collectd and Graphite can increase software development productivity and quality at the same time.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

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).
