An Overview of RUP methodology
This presentation gives you a complete overview of RUP (Rational Unified Process) methodology. The presentation come with fail deal of slide comments.
Hazop Hazard and Operability Study
A Hazard and Operability (HAZOP) study is a structured and systematic examination of a planned or existing process or operation in order to identify and evaluate problems that may represent risks to personnel or equipment, or prevent efficient operation.
The HAZOP technique was initially developed to analyze chemical process systems, but has later been extended to other types of systems and also to complex operations and to software systems.

A Water Fall Model is easy to flow.
It can be implemented for any size of project.
Every stage has to be done separately at the right time so you cannot jump stages.
Documentation is produced at every stage of a waterfall model allowing people to understand what has been done.
Testing is done at every stage.
This model was not the first model to discuss iterative development.
As originally envisioned, the iterations were typically 6 months to 2 years long.
Each phase starts with a design goal and ends with the client (who may be internal) reviewing the progress thus far.
Analysis and engineering efforts are applied at each phase of the project, with an eye toward the end goal of the project.

Process hazard analysis 13,47
This document discusses hazard analysis, which allows employers to identify potential safety problems and corrective measures to improve safety. It describes several hazard analysis techniques including What-If analysis, checklists, Hazard and Operability Studies, and Failure Mode and Effects Analysis. What-If analysis involves experienced personnel brainstorming "What if?" questions to evaluate potential process hazards and failures. Checklists consist of yes/no questions about facility design and operation. Hazard and Operability Studies identify safety hazards and operational problems. While no technique can identify all accident scenarios, hazard analysis plays an important role in reducing industrial accidents when rigorously applied.
Process hazard analysis (pha)
A hazard is a situation that poses a level of threat to life, health, property, or environment. Most hazards are dormant or potential, with only a theoretical risk of harm; however, once a hazard becomes "active", it can create an emergency. Hazard and possibility interact together to create risk.
Identification of hazard risks is the first step in performing a risk assessment.
Hazard analysis
This document discusses process hazard analysis (PHA). It defines hazards as inherent characteristics that can cause harm. PHA allows employers to identify potential safety problems, corrective measures, and emergency plans. The analysis must be performed by a team with relevant expertise using an established methodology. It must address hazards, previous incidents, engineering controls, consequences of control failure, and more. Common methodologies include What-If analysis, checklists, HAZOP, FMEA, and fault tree analysis. The document concludes that companies using rigorous PHA are seeing reductions in accident frequency and severity.
Network cabling
What is Network Cabling?
Cable is the medium through which information usually moves from one network device to another.
There are several types of cable which are commonly used with LANs. In some cases, a network will utilize only one type of cable, other networks will use a variety of cable types. The type of cable chosen for a network is related to the network's topology, protocol, and size.
Barcode 63,70
As far back as the 1960s, barcodes were used in industrial work environments. Some of the early implementations of barcodes included the ability identify rail,road,cars,etc……
In the early 1970s, common barcodes started appearing on grocery shelves. To automate the process of identifying grocery items, UPC barcodes were placed on products.
Today, barcodes are just about everywhere and are used for identification in almost all types of business.
Poverty
This document discusses concepts related to poverty, including definitions of poverty lines and methods for measuring poverty. It outlines several key causes of poverty, such as low economic growth, population pressure, unemployment, and outdated social institutions. Finally, it lists some measures that can be taken to reduce poverty, like accelerating economic growth, reducing income inequality through legislation, controlling population growth, and improving quality of life for the poor.
filters
Filters are used to selectively pass or block ranges of frequencies in electronic circuits. The main types are low-pass filters, which pass low frequencies and block high frequencies; high-pass filters, which do the opposite; band-pass filters, which pass a band of frequencies; and band-stop or band-reject filters, which block a band of frequencies. Filters can be built using passive components like resistors, capacitors, and inductors in configurations like RC, RL, RLC, pi, and T networks or can use active components like op-amps. The document discusses examples and circuit diagrams of each main filter type.
Quadcopter final report anand
This document provides an overview of a quadcopter project. It introduces the project supervisor and describes the structure, design, control theory, and sensors of a quadcopter. It explains that quadcopters use four motors and propellers for lift and are controlled electronically rather than with complex mechanical systems like helicopters. It also discusses the PID control algorithm used to stabilize the quadcopter based on sensor feedback and error calculations. Sensor fusion is described as important for combining gyroscope and accelerometer readings to reduce noise and drift in the orientation estimates.

EWOCS-I: The catalog of X-ray sources in Westerlund 1 from the Extended Weste...
Context. With a mass exceeding several 104 M⊙ and a rich and dense population of massive stars, supermassive young star clusters
represent the most massive star-forming environment that is dominated by the feedback from massive stars and gravitational interactions
among stars.
Aims. In this paper we present the Extended Westerlund 1 and 2 Open Clusters Survey (EWOCS) project, which aims to investigate
the influence of the starburst environment on the formation of stars and planets, and on the evolution of both low and high mass stars.
The primary targets of this project are Westerlund 1 and 2, the closest supermassive star clusters to the Sun.
Methods. The project is based primarily on recent observations conducted with the Chandra and JWST observatories. Specifically,
the Chandra survey of Westerlund 1 consists of 36 new ACIS-I observations, nearly co-pointed, for a total exposure time of 1 Msec.
Additionally, we included 8 archival Chandra/ACIS-S observations. This paper presents the resulting catalog of X-ray sources within
and around Westerlund 1. Sources were detected by combining various existing methods, and photon extraction and source validation
were carried out using the ACIS-Extract software.
Results. The EWOCS X-ray catalog comprises 5963 validated sources out of the 9420 initially provided to ACIS-Extract, reaching a
photon flux threshold of approximately 2 × 10−8 photons cm−2
s
−1
. The X-ray sources exhibit a highly concentrated spatial distribution,
with 1075 sources located within the central 1 arcmin. We have successfully detected X-ray emissions from 126 out of the 166 known
massive stars of the cluster, and we have collected over 71 000 photons from the magnetar CXO J164710.20-455217.
The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptx
Although Artemia has been known to man for centuries, its use as a food for the culture of larval organisms apparently began only in the 1930s, when several investigators found that it made an excellent food for newly hatched fish larvae (Litvinenko et al., 2023). As aquaculture developed in the 1960s and ‘70s, the use of Artemia also became more widespread, due both to its convenience and to its nutritional value for larval organisms (Arenas-Pardo et al., 2024). The fact that Artemia dormant cysts can be stored for long periods in cans, and then used as an off-the-shelf food requiring only 24 h of incubation makes them the most convenient, least labor-intensive, live food available for aquaculture (Sorgeloos & Roubach, 2021). The nutritional value of Artemia, especially for marine organisms, is not constant, but varies both geographically and temporally. During the last decade, however, both the causes of Artemia nutritional variability and methods to improve poorquality Artemia have been identified (Loufi et al., 2024).
Brine shrimp (Artemia spp.) are used in marine aquaculture worldwide. Annually, more than 2,000 metric tons of dry cysts are used for cultivation of fish, crustacean, and shellfish larva. Brine shrimp are important to aquaculture because newly hatched brine shrimp nauplii (larvae) provide a food source for many fish fry (Mozanzadeh et al., 2021). Culture and harvesting of brine shrimp eggs represents another aspect of the aquaculture industry. Nauplii and metanauplii of Artemia, commonly known as brine shrimp, play a crucial role in aquaculture due to their nutritional value and suitability as live feed for many aquatic species, particularly in larval stages (Sorgeloos & Roubach, 2021).

Authoring a personal GPT for your research and practice: How we created the Q...
Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.

We will metaverse into the essence of immersive learning, into its three dimensions and conceptual models. This approach encompasses elements from teaching methodologies to social involvement, through organizational concerns and technologies. Challenging the perception of learning as knowledge transfer, we introduce a 'Uses, Practices & Strategies' model operationalized by the 'Immersive Learning Brain' and ‘Immersion Cube’ frameworks. This approach offers a comprehensive guide through the intricacies of immersive educational experiences and spotlighting research frontiers, along the immersion dimensions of system, narrative, and agency. Our discourse extends to stakeholders beyond the academic sphere, addressing the interests of technologists, instructional designers, and policymakers. We span various contexts, from formal education to organizational transformation to the new horizon of an AI-pervasive society. This keynote aims to unite the iLRN community in a collaborative journey towards a future where immersive learning research and practice coalesce, paving the way for innovative educational research and practice landscapes.
Phenomics assisted breeding in crop improvement
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.
ESR spectroscopy in liquid food and beverages.pptx
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.

Hazop Hazard and Operability Study
- 1. Presented By: Ashwani Kumar (2012-65) Sagar Verma(2012-07)
- 2. What is HAZOP? A Hazard and Operability (HAZOP) study is a structured and systematic examination of a planned or existing process or operation in order to identify and evaluate problems that may represent risks to personnel or equipment, or prevent efficient operation. A HAZOP is a qualitative technique based on guide-words and is carried out by a HAZOP team during a set of meetings. 2
- 3. BACK GROUND The HAZOP technique was initially developed to analyze chemical process systems, but has later been extended to other types of systems. First main textbook: Kletz, T. A.: “Hazop and Hazan -Identifying and Assessing Process Industry Hazards”, Institution of Chemical Engineers. 3
- 4. When to Use? Optimal from a cost viewpoint 1. when applied to new plants at the point where the design is nearly firm and documented or 2.to existing plants where a major redesign is planned. It can also be used for existing facilities.
- 5. Principles of HAZOP Concept •Systems work well when operating under design conditions. •Problems arise when deviations from design conditions occur. Basis •a word model, a process flow sheet (PFD) or a piping and instrumentation diagram (P&ID) Method •use guide words to question every part of process to discover what deviations from the intention of design can occur and what are their causes and consequences may be.
- 6. GUIDE WORDS Guide Words No, None More Of Less Of As Well As (More Than) Part Of Reverse Other Than Meaning Negation of Intention Quantitative Increase Quantitative Decrease Qualitative Increase Qualitative Decrease Logical Opposite of Intention Complete Substitution
- 7. EXAMPLE The flowsheet shows that raw material streams A and B are transferred by pump to a reactor, where they react to form product C. Assume that the flow rate of B should not exceed that of A. Otherwise, an explosion may occur. Let’s consider the flow of A in line 1: NONE No flow of A MORE Flow of A greater than design flow LESS Flow of A less than design flow AS WELL AS Transfer of some component additional to A PART OF Failure to transfer a component of A REVERSE Flow of A in a direction opposite to design direction OTHER THAN Transfer of some material other than A A B C B A B F F
