Adding Real-time Features to PHP ApplicationsRonny López
It's possible to introduce real-time features to PHP applications without deep modifications of the current codebase.
Using WAMP you can build distributed systems out of application components which are loosely coupled and communicate in (soft) real-time.
There is no need to learn a whole new language, with the implications it has.
It also opens the door to write reactive, event-based, distributed architectures and to achieve easier scalability by distributing messages to multiple systems.
Why do requirements need to be managed?
- Fewer requirements defects
- Reduce development rework
- Fewer unnecessary features
- Lower enhancement costs
- Faster development
- Fewer miscommunications
- Reduced scope creep
- Reduced project Chaos
- More accurate system testing estimates
- High customer and team members satisfaction
Performance testing is testing an application for speed, stability and scalability in “Production like Environment” under virtual user load to meet Non-Functional requirements

Skills that are adequate to build a small system will not suffice to build a larger system. This slidedeck was used in a talk where the differences were highlighted and methods and techniques to build large systems recommended.
Data processing is an integral part of most modern software development. Understanding of Abstract Algebra and Category theory will be beneficial for addressing data processing concerns.
software development practices like procedural coding are like training wheels, they help when we start development, but are detrimental later. This presentation lists few such practices and their alternatives
Using recycled concrete aggregates (RCA) for pavements is crucial to achieving sustainability. Implementing RCA for new pavement can minimize carbon footprint, conserve natural resources, reduce harmful emissions, and lower life cycle costs. Compared to natural aggregate (NA), RCA pavement has fewer comprehensive studies and sustainability assessments.
NUMERICAL SIMULATIONS OF HEAT AND MASS TRANSFER IN CONDENSING HEAT EXCHANGERS...ssuser7dcef0
Power plants release a large amount of water vapor into the
atmosphere through the stack. The flue gas can be a potential
source for obtaining much needed cooling water for a power
plant. If a power plant could recover and reuse a portion of this
moisture, it could reduce its total cooling water intake
requirement. One of the most practical way to recover water
from flue gas is to use a condensing heat exchanger. The power
plant could also recover latent heat due to condensation as well
as sensible heat due to lowering the flue gas exit temperature.
Additionally, harmful acids released from the stack can be
reduced in a condensing heat exchanger by acid condensation. reduced in a condensing heat exchanger by acid condensation.
Condensation of vapors in flue gas is a complicated
phenomenon since heat and mass transfer of water vapor and
various acids simultaneously occur in the presence of noncondensable
gases such as nitrogen and oxygen. Design of a
condenser depends on the knowledge and understanding of the
heat and mass transfer processes. A computer program for
numerical simulations of water (H2O) and sulfuric acid (H2SO4)
condensation in a flue gas condensing heat exchanger was
developed using MATLAB. Governing equations based on
mass and energy balances for the system were derived to
predict variables such as flue gas exit temperature, cooling
water outlet temperature, mole fraction and condensation rates
of water and sulfuric acid vapors. The equations were solved
using an iterative solution technique with calculations of heat
and mass transfer coefficients and physical properties.
A review on techniques and modelling methodologies used for checking electrom...nooriasukmaningtyas
The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.
Understanding Inductive Bias in Machine LearningSUTEJAS
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.
Online aptitude test management system project report.pdfKamal Acharya
The purpose of on-line aptitude test system is to take online test in an efficient manner and no time wasting for checking the paper. The main objective of on-line aptitude test system is to efficiently evaluate the candidate thoroughly through a fully automated system that not only saves lot of time but also gives fast results. For students they give papers according to their convenience and time and there is no need of using extra thing like paper, pen etc. This can be used in educational institutions as well as in corporate world. Can be used anywhere any time as it is a web based application (user Location doesn’t matter). No restriction that examiner has to be present when the candidate takes the test.
Every time when lecturers/professors need to conduct examinations they have to sit down think about the questions and then create a whole new set of questions for each and every exam. In some cases the professor may want to give an open book online exam that is the student can take the exam any time anywhere, but the student might have to answer the questions in a limited time period. The professor may want to change the sequence of questions for every student. The problem that a student has is whenever a date for the exam is declared the student has to take it and there is no way he can take it at some other time. This project will create an interface for the examiner to create and store questions in a repository. It will also create an interface for the student to take examinations at his convenience and the questions and/or exams may be timed. Thereby creating an application which can be used by examiners and examinee’s simultaneously.
Examination System is very useful for Teachers/Professors. As in the teaching profession, you are responsible for writing question papers. In the conventional method, you write the question paper on paper, keep question papers separate from answers and all this information you have to keep in a locker to avoid unauthorized access. Using the Examination System you can create a question paper and everything will be written to a single exam file in encrypted format. You can set the General and Administrator password to avoid unauthorized access to your question paper. Every time you start the examination, the program shuffles all the questions and selects them randomly from the database, which reduces the chances of memorizing the questions.
3. Ads Quality
• many reviewers, categorized into two buckets :-
• Software: ML models, content of ads(regexs, all caps, emojis, embedded
links), history of advertiser
• Human reviewers: Inspector/Review Queue.
4. • many ad types
• review logic can vary per ad-type
• review logic can vary over time
5. • certain ad types require permissions/certifications
• cost/capacity of reviewers need to be considered
6.
7. Problems
• Each Reviewer has different schema to communicate with each other
and need to track all communication themselves.
• Difficult to track lifecyle of an ad
• Difficult to track performance of each reviewer
• Low developer productivity
13. Value is created in interactions between
suppliers and producers(roles)
The platform regulates and manages activity
by creating conditions for interactions
47. Applying DRY on behavior of a Reviewer
• Communicates with each other asynchronously
• Each reviewers has a kafka topic with specific schema to get requests
to review
• Calls other reviewers with their different event schemas
• Receive Response In terms of an event from reviewers which were
invoked via kafka.
• Returns response to caller by sending an Event with some specific
schema like ReviewItemClosedMessage etc.
48. First Abstraction
• They have the port to review an ad.
• They have the port to get response from other reviewers.
50. Server
• public interface Server {
Task<Response> review(
@NonNull Reviewee reviewee,
@NonNull Actor client,
@NonNull ReviewSession session);
}
Reviewee - Ad information
Client – caller which request for review
Session – session of a review (guid)
51. Client
• public interface Client {
Task<Response> onReview(
@NonNull Reviewee reviewee,
@NonNull Actor server,
@NonNull ReviewSession session,
@NonNull ReviewDecision reviewDecision);
}
Reviewee - Ad information
Client – caller which request for review
Session – session of a review (guid)
Review Decision – decision of a server (target reviewer)
52. • Kafka Event Schema
• Address of target reviewer i.e. kafka topic of target reviewer
• Just have to know identifier of other reviewer
Reviewers should not care about
54. TSCP Review Api Library
(Platform provided construct)
It has the responsibility of
• taking care of resolving target topic of kafka or may be restli endpoint
of target reviewer.
• It converts review request or review response into required common
kafka message schemas.
56. Kafka Schemas
Only 2 avro schemas for communication across reviewers
• ReviewRequestMessage - details of ad, caller, header, sessiom
• ReviewResponseMessage – decision of a reviewer
57. Server Stub
Similar concept to RPC
• It acts as a server proxy
• Construct and send a
ReviewRequestMessage kafka message
58. Client Stub
Similar concept to RPC
• It acts as a client proxy
• Construct and send a
ReviewResponseMessage as a kafka
message
59. Reviewer Registry
• Resolver of client and server based on urn(namespace and id) of a
reviewer.
• It has list of all ports and corresponding kafka topics.
63. ReviewerGeneratorFactory
• Takes input as List of Reviewers
• Starts Kafka Client and kafka Server Listeners for
all reviewers with the help of ReviewerRegistry
