Role of system analyst
A system analyst performs three main roles:
1. They research problems within an organization's existing systems and processes, plan solutions to improve efficiency and productivity, and recommend new hardware and software systems.
2. They act as an agent of change by introducing new IT systems and working to minimize resistance to changes.
3. They investigate issues with current systems, monitor new systems, and gather facts and opinions from users to define requirements and solve problems.
System Analyst
The system analyst is responsible for converting customer needs and requirements into computerized systems. They must have strong technical skills to work with programmers, developers, and administrators, as well as good communication and presentation skills to understand customers and present systems. As the role requires interacting with many different departments, system analysts must be good problem solvers, creative thinkers, and able to work with a variety of people.
System analysis
System analysis involves defining users' goals and usage patterns, inventing functional solutions to meet those goals, defining navigation paths, creating UI mockups, and polishing interface elements. Data is raw material that is collected and processed into information, which is then used by managers to run organizations efficiently. The key characteristics of a system are organization, interaction, interdependence, and integration toward a central objective, while its core elements are inputs/outputs, a processor, control, feedback, boundaries/interfaces, and environment.

DEPENDABLE PRIVACY REQUIREMENTS BY AGILE MODELED LAYERED SECURITY ARCHITECTUR...
Software Engineering covers the definition of processes, techniques and models suitable for its
environment to guarantee quality of results. An important design artifact in any software
development project is the Software Architecture. Software Architecture’s important part is the
set of architectural design rules. A primary goal of the architecture is to capture the
architecture design decisions. An important part of these design decisions consists of
architectural design rules In an MDA (Model-Driven Architecture) context, the design of the
system architecture is captured in the models of the system. MDA is known to be layered
approach for modeling the architectural design rules and uses design patterns to improve the
quality of software system. And to include the security to the software system, security patterns
are introduced that offer security at the architectural level. More over, agile software
development methods are used to build secure systems. There are different methods defined in
agile development as extreme programming (XP), scrum, feature driven development (FDD),
test driven development (TDD), etc. Agile processing is includes the phases as agile analysis,
agile design and agile testing. These phases are defined in layers of MDA to provide security at
the modeling level which ensures that security at the system architecture stage will improve the
requirements for that system. Agile modeled Layered Security Architectures increase the
dependability of the architecture in terms of privacy requirements. We validate this with a case
study of dependability of privacy of Web Services Security Architectures, which helps for secure
service oriented security architecture. In this paper the major part is given to model
architectural design rules using MDA so that architects and developers are responsible to
automatic enforcement on the detailed design and easy to understand and use by both of them.
This MDA approach is implemented in use of Agile strategy in three different phases covering
three different layers to provide security to the system. With this procedure a premise
conclusion has been given that with the system security the requirements for that system are
improved. This paper summarizes that security is essential for every system at initial stage and
upon introduction of security at middle stage must lead to the change in the system i.e., an
improvement to system requirements.

Low power architecture of logic gates using adiabatic techniques
The growing significance of portable systems to limit power consumption in ultra-large-scale-integration chips of very high density, has recently led to rapid and inventive progresses in low-power design. The most effective technique is adiabatic logic circuit design in energy-efficient hardware. This paper presents two adiabatic approaches for the design of low power circuits, modified positive feedback adiabatic logic (modified PFAL) and the other is direct current diode based positive feedback adiabatic logic (DC-DB PFAL). Logic gates are the preliminary components in any digital circuit design. By improving the performance of basic gates, one can improvise the whole system performance. In this paper proposed circuit design of the low power architecture of OR/NOR, AND/NAND, and XOR/XNOR gates are presented using the said approaches and their results are analyzed for powerdissipation, delay, power-delay-product and rise time and compared with the other adiabatic techniques along with the conventional complementary metal oxide semiconductor (CMOS) designs reported in the literature. It has been found that the designs with DC-DB PFAL technique outperform with the percentage improvement of 65% for NOR gate and 7% for NAND gate and 34% for XNOR gate over the modified PFAL techniques at 10 MHz respectively.

3-6 June 2024, Niš, SerbiaUnderstanding Inductive Bias in Machine Learning
This presentation explores the concept of inductive bias in machine learning. It explains how algorithms come with built-in assumptions and preferences that guide the learning process. You'll learn about the different types of inductive bias and how they can impact the performance and generalizability of machine learning models.
The presentation also covers the positive and negative aspects of inductive bias, along with strategies for mitigating potential drawbacks. We'll explore examples of how bias manifests in algorithms like neural networks and decision trees.
By understanding inductive bias, you can gain valuable insights into how machine learning models work and make informed decisions when building and deploying them.

Requirement elicitation techniques for software
- 1. REQUIREMENT ELICITATION TECHNIQUES FOR SOFTWARE Arbab (23126) Qasim Ali (22772) Adeel hassan ( ) Submited by :
- 2. REQUIREMENT ELICITATION Requirements elicitation is the collection of the requirements of any given system or product from users, customers and other important stakeholders
- 3. REQUIREMENT GATHERING TECHNIQUE Stake holder analysis Brainstorming One on one interview Group Interview Document Analysis Focus Group Interface Analysis Observation Prototyping Requirements Workshop Reverse Engineering Survey
- 4. STAKE HOLDER ANALYSIS Definition: Stake holder analysis identifies all the user and stakeholders who may influence or be impacted by the system. This this help ensure that the needs of all those involved are taken into account. Benefits: Ensure that all relevant stakeholder are considered All important stakeholder are captured, yet that irrelevant actors are not included. Drawbacks: There is danger that to much time is spent on identifying roles and relationships and the teams is swamped data.
- 5. BRAINSTORMING Definition: It is utilized in requirements elicitation to gather good number of ideas from a group of people. Usually brainstorming is used in identifying all possible solutions to problems and simplifies the detail of opportunities. Basic Rules Generate may idea as possible Let your imagination soar It casts a broad net, determining various discreet possibilities. Benefits Generate the variety of idea in a short time Produce new and creative ideas
- 6. ONE ON ONE INTERVIEW Definition: The most common technique for gathering requirements is to sit down with the clients and ask them that they need. The discussion should be planned out ahead of time based on the type of requirements you are looking for benefits Privacy of everyone in-depth a stakeholder thoughts and get his or her perspective Risks: Time consuming Misunderstanding
- 7. INTERVIEW Interviews of users and stakeholders are important in creating wonderful software. Without knowing the expectations and goal of the stakeholders and users, you are highly unlikely to satiate them
