The document discusses techniques for decomposing software projects to aid in cost estimation. It describes decomposing by problem or process. Process decomposition breaks down framework activities like communication. For complex projects, communication can be broken into smaller tasks. The document also discusses software sizing methods, empirical estimation models, and making buy versus build decisions. It outlines manual and automated cost estimation techniques from project-level to activity-level estimates.

The document discusses different types of data sets and various concepts related to data preprocessing. It describes common data types like records, relational data, and transaction data. It also defines key concepts in data preprocessing like data objects, attributes, handling missing/noisy data, data integration, reduction, transformation and discretization. The goal of these techniques is to clean, integrate and prepare raw data for analysis.

Clustering.pdfsaman Iftikhar

��

Clustering is an unsupervised learning technique that groups similar objects together. It involves grouping data points such that items in the same cluster are more similar to each other than items in different clusters. This document discusses and compares several clustering algorithms, including K-means, K-medoids, and hierarchical clustering. It also covers applications of clustering in domains such as marketing, astronomy, genomics, and more.

Science saman Iftikhar

��

The document discusses the five senses and sense organs in humans. It describes how sensory cells receive stimuli from the environment and group together to form sense organs like the skin, nose, tongue, eye and ear. It then focuses on describing the skin in more detail, including its layers - the epidermis and dermis. It notes the functions of skin, including protection, temperature control, and its role as a sense organ for touch, pain, pressure, heat and cold. It discusses the key cell types and structures involved in the skin and sensory processes.

This document discusses operating system protection and security. It defines protection as controlling access to system resources and ensuring enforcement of access policies. The goals of protection are to ensure objects are only accessed correctly by allowed processes. Security focuses on malicious external threats, while protection handles internal access control. The document outlines various attacks, authentication methods, and types of malware like viruses, worms, and trojans. It also describes domain-based access control and implementation in UNIX using user IDs.

Interface andexceptionssaman Iftikhar

��

An exception occurs when the normal flow of a program is disrupted, such as dividing by zero or accessing an out-of-bounds array element. Exceptions are handled using try-catch blocks to catch specific exceptions or finally blocks to clean up resources. Methods can throw exceptions using the throw statement or specify thrown exceptions in the method declaration using throws. Programmers can also create custom exception classes by extending the Exception class.

Ethical principles in psychological researchsaman Iftikhar

��

This document discusses ethics in psychological research. It defines ethics as moral principles that govern behavior or activities. Ethics in psychology refers to correctly following rules to protect research participants from harm while respecting their rights. The American Psychological Association establishes guidelines for ethical research including obtaining informed consent, avoiding deception, protecting participants' safety, maintaining confidentiality, allowing withdrawal from studies, and debriefing participants after a study. Key ethical factors are avoiding pressure, ensuring safety, giving proper credit, and maintaining communication with participants.

polysemy tag detect in tag setssaman Iftikhar

��

The document presents a methodology for detecting polysemy tags in a tag set using WordNet and Wikipedia. The methodology retrieves tags and URLs from Delicious RSS feeds as an experimental dataset. Polysemy words in the tag sets are detected using WordNet definitions and Wikipedia pages. The results show that WordNet alone cannot detect all polysemy tags, but the addition of Wikipedia improves accuracy. The approach is evaluated based on the types of polysemy detected, and it is able to identify common types like contrastive and complementary polysemy but not rare types. Future work could focus on detecting more uncommon polysemy types.

Selectionsaman Iftikhar

��

The document outlines the 8 steps of the selection process: 1) blank application form, 2) preliminary interview, 3) employee testing, 4) employment interview, 5) reference checking, 6) medical examination, 7) decision making, and 8) induction. The selection process involves choosing qualified candidates through application forms, interviews, tests, and examinations to fill positions in an organization.

Pipelinesaman Iftikhar

��

A pipeline is a series of processing elements where the output of one element is input to the next. Pipelines can operate sequentially or in parallel. Common types of pipelines include instruction pipelines in CPUs, graphics pipelines in GPUs, software pipelines using system calls, and HTTP pipelining. The key aspect of pipeline design is balancing stage processing times so the pipeline outputs finished items at the rate of its slowest stage. Reservation tables are used to visualize scheduling in pipelines. Multiprocessing uses multiple CPUs connected with shared memory and I/O to boost system speed, provide fault tolerance, and better match applications.

Context diagramsaman Iftikhar

��

A context diagram shows the system boundaries and major information flows between external entities and the system. It indicates people, organizations, and systems that communicate with the system, and depicts the data received from and sent to the outside world. A context diagram is also known as a level 0 data flow diagram, showing the system's major processes, data flows, and data stores at a high level of abstraction. Examples of context diagrams are presented.

Databasesaman Iftikhar

��

The document provides instructions for creating different objects in Microsoft Access: a table, form, report, query, and labels. It describes opening Access, using the design view to create a table with fields and data types, and entering data. It also lists the steps to use the form and report wizards to generate a form and report. Creating a query involves using the query wizard to select specific fields. Finally, it notes that labels can be generated by clicking on labels under the create option menu.

Flags registerssaman Iftikhar

��

This document discusses flag usage in computing. It explains that the flag register contains 16 bits that show the status of operations, with 9 bits indicating the current status. There are status flags like carry, zero, and sign that reflect the outcome of arithmetic operations. Additionally, there are control flags that direct CPU operations. Examples are provided to illustrate how specific instructions affect the flags.

Y - Recursion The Hard Way GopherCon EU 2025Eleanor McHugh

��

In most modern programming languages, including Go, it's possible for a function to call itself recursively. It's such a mainstream technique that we've come to take it for granted. But what if functions couldn't call themselves? There's a branch of mathematics called Combinatorics which answers just these kinds of questions, and this presentation takes these ideas and phrases them in Go to teach a deeper view of computation through the medium of code.

Threat Modeling a Batch Job Framework - Teri Radichel - AWS re:Inforce 20252nd Sight Lab

��

This presentation is similar to another presentation I gave earlier in the year at the AWS Community Security Day, except that I had less time to present and incorporated some AI slides into the presentation. In this presentation I explain what batch jobs are, how to use them, and that AI Agents are essentially batch jobs. All the same security controls that apply to batch jobs also apply to AI agents. In addition, we have more concerns with AI agents because AI is based on a statistical model. That means that depending on where and how AI is used we lose some of the reliability that we would get from a traditional batch job. That needs to be taken into consideration when selecting how and when to use AI Agents as batch jobs and whether we should use AI to trigger an Agent. As I mention on one side - I don't want you to predict what my bank statement should look like. I want it to be right! By looking at various data breaches we can determine how those attacks worked and whether the system we are building is susceptible to a similar attack or not.
