SysML v2 is an upcoming version of the Systems Modeling Language that aims to address limitations in the current version (v1). It has a formal foundation using KerML, a new metamodel that is not limited by being a UML profile, and a textual notation to integrate with existing technologies. A standardized API will also allow SysML tooling to better interoperate. The goal of these changes is to enable effective model-based systems engineering by putting system models with real meaning and semantics at the center.

Introduction to the OMG Systems Modeling Language (SysML), Version 2
Tutorial presented at the MODELS 2020 virtual conference on the proposed OMG Systems Modeling Language, Version 2, as of the initial submission of the specification.
SysML v2 and the Next Generation of Modeling Languages
The Systems Modeling Language (SysML) is a particularly successful offshoot of the Unified Modeling Language (UML) tailored for Model-Based Systems Engineering. After a decade of growing use of SysML, in 2017 the Object Management Group (OMG) issued a Request for Proposals (RFP) for a new version of the language. A year into the ongoing work to respond to this RFP, it is clear that SysML v2 needs to be more than just an expansion of the functional capabilities of SysML. Rather, it must address fundamental architectural issues that have made it difficult to further evolve SysML v1 to address the needs of its user community. Therefore, the language is being re-designed using a new kernel metamodel with formally grounded semantics. This kernel can then be extended using semantic model libraries, rather than by expanding the language metamodel itself. This approach will allow SysML v2 to be not only the modeling language for traditional systems engineering, but also the foundation for a whole new generation of modeling languages.
SysML v2 and MBSE: The next ten years
SysML v2 aims to enhance SysML over the next decade to further increase adoption of model-based systems engineering (MBSE). Key areas of focus for SysML v2 include improving the precision and expressiveness of the language, integrating language concepts more consistently, improving interoperability with other tools, and enhancing usability. A submission team is developing SysML v2 based on user needs and requirements from requests for proposals, taking an agile and collaborative approach. Usage-focused modeling is a proposed paradigm shift that emphasizes modeling system usages over structure to make SysML more intuitive.

We know change can be intimidating. The coming release of SysML V2 can seem intimidating, as it is a product of 70 organizations and 170 people collaborating. Join us for our next webinar, “Dissecting SysML V2,” with Systems Engineer, Lilleigh Stevie. We will look closely at the next generation of OMG’s modeling language by covering its background, purpose and objectives, KerML, familiar and new concepts, pilot implementation, and where this will take us in the future. There will be a designated time at the end for questions, so bring any you may have with you. Register today and we will see you there!
Executable UML and SysML Workshop
This is a one day workshop presentation, primarily on the new OMG Foundational UML specification for executable model semantics, but also discussing extensions for executable SysML (System Modeling Language) models.
Equivalences and diffrences between SysML and Arcadia / Capella
The document is a presentation on equivalences and differences between SysML and Arcadia/Capella. It provides high-level positioning of the modeling languages and methods, outlines several diagram types that have similarities between SysML and Capella, and identifies three main differences. The presentation aims to help people understand how Capella relates to SysML while having a simpler learning curve for systems engineers.
Capella Days 2021 | Introduction to CAPELLA/ARCADIA and NASA Systems Engineer...
The NASA System Engineering (SE) handbook aims to provide general guidance and information on systems engineering, as it should be applied throughout NASA. The handbook introduces 3 common technical processes. One of these, is the System Design Process, describing the stakeholders expectations, requirements definition, logical decomposition and design solution definition. The 4 activities can be supported by a Model-Based Systems Engineering (MBSE) approach. To do so, an appropriate method and tool is necessary as the one provided by the ARChitecture Analysis & Design Integrated Approach.
ARCADIA, with its modeler CAPELLA, is a MBSE solution supporting system modeling activities. Based on 4 architectural layers, which are Operational Analysis, System Analysis, Logical and Physical Architecture, it is a structured architecture engineering method for defining and validating multi-domain systems.
This talk will present an educational overview of the ARCADIA methodology and System Design Process from the NASA SE, by introducing MBSE artefacts for space system.
The HUBBLE Space Telescope (HST) is a Cassegrain reflector telescope. Orbiting above the earth, HST elaborates a clear view of the universe free from the blurring and absorbing effects of the atmosphere. In order to illustrate the journey throughout CAPELLA, the HST will be introduced, as example, based on public information available.
Improving MBSE maturity with open-source tool Capella
MBSE aims at transitioning the Systems Engineering practice from a document-centric approach to a model-centric approach. It is envisioned to be the next shift enhancing significantly our systems engineering capacities, in order to cope with the steadily growing systems' complexity. Although MBSE has been a trending topic over the last few years, its adoption among systems engineers is still growing slowly.
In this presentation, Stephane Lacrampe will introduced some of the challenges in MBSE adoption and explained how the Arcadia method and the Capella tool are enablers for accelerating MBSE adoption among the systems engineering community.

From Monolithic to Microservices
This document discusses the transition from monolithic architecture to microservices architecture. It begins by outlining challenges with monolithic systems like long development cycles and difficulties scaling. It then defines microservices as loosely coupled services that have bounded contexts. The document provides examples of how to evolve a monolith to microservices by starting with existing services and gradually decomposing the monolith. It acknowledges challenges in distributed systems and eventual consistency that come with microservices. Overall, the document presents microservices as enabling faster innovation, increased agility and delighted customers compared to monolithic systems.
Solution Architecture
The document defines the roles of solution architect, enterprise architect, and technical architect. It states that a solution architect is responsible for converting business requirements into an architectural design and blueprint for a solution. The solution architect needs input from stakeholders and provides outputs like application, database, infrastructure, and implementation designs. It also outlines the differences between the roles, noting that an enterprise architect focuses on enterprise-wide strategy, a solution architect focuses on delivering a specific solution, and a technical architect specializes in particular technologies within a solution. Finally, it shows how a solution architect contributes throughout the total life cycle of a solution.

Derek Chiles, AWS Solutions Architect, will review best practices and recommended architectures for deploying microservices on AWS.
Service-mesh options with Linkerd, Consul, Istio and AWS AppMesh
Service mesh abstracts the network from developers to solve three main pain points:
How do services communicate securely with one another
How can services implement network resilience
When things go wrong, can we identify what and why
Service mesh implementations usually follow a similar architecture: traffic flows through control points between services (usually service proxies deployed as sidecar processes) while an out-of-band set of nodes is responsible for defining the behavior and management of the control points. This loosely breaks out into an architecture of a "data plane" through which requests flow and a "control plane" for managing a service mesh.
Different service mesh implementations use different data planes depending on their use cases and familiarity with particular technology. The control plane implementations vary between service-mesh implementations as well. In this talk, we'll take a look at three different control plane implementations with Istio, Linkerd and Consul, their strengths, and their specific tradeoffs to see how they chose to solve each of the three pain points from above. We can use this information to make choices about a service mesh or to inform our journey if we choose to build a control plane ourselves.

MBSE with Arcadia method step-by-step Physical Architecture.pdf
The objective of the Physical Architecture in defining the “real” concrete components that comprise the system. To start the Physical level based on the Logical level, Capella proposes transitions similar to those that we used when we went from the Operational Analysis to the System Analysis, then from the System Analysis to the Logical Architecture. Thus, it can be created as many Physical Functions as Logical Functions, by also keeping the Functional Exchanges and Functional Chains.
Running containers in production, the ING story
- ING is transforming itself into a digital bank and using containers and microservices as part of its cloud native journey.
- ING has developed its own container hosting platform called ICHP, which runs on OpenShift and provides self-service capabilities for development teams to host applications.
- ICHP aims to provide reliable hosting while minimizing handovers and enabling development teams to focus on delivering value to the business rather than managing infrastructure.
MLOps with Azure DevOps
MLOps refers to applying DevOps practices and principles to machine learning. This allows for machine learning models and projects to be developed and deployed using automated pipelines for continuous integration and delivery. MLOps benefits include making machine learning work reproducible and auditable, enabling validation of models, and providing observability through monitoring of models after deployment. MLOps uses the same development practices as software engineering to ensure quality control for machine learning.
Living the AWS Well Architected Framework
Uturn Data Solutions presentation on the AWS Well Architected Framework - AWS Chicago Summit - August 2, 2018
Tailoring Arcadia Framework in Thales UK
Architecture frameworks provide an approach to describing systems and the presentation of these elements and relationships to deliver the stakeholder needs. Essentially, frameworks provide templates for our engineering artefacts.
The design of a framework must accommodate a level of freedom in its usage; specific enough to answer the majority of stakeholder concerns whilst generic enough to allow for differences between projects. This balancing act often results in framework design being more generic to allow for a wider audience. Having an untailored framework, which is more ‘open’, can lead to creating inconsistent viewpoints.
Arcadia is one such framework as implemented through the Capella tool. The framework provides 4 perspectives/levels for product definition:
- The Operational Analysis, where the user needs are considered. Note: no concept of the System at this level.
- The System Analysis, where we define the contribution and scope of the System as a ‘black box’, identifying external interfaces, and top-level system functions.
- The Logical Architecture, where we break the System down into logical ‘blocks’ and decompose the functionality.
- The Physical Architecture, in which we define a (candidate) physical architecture, further decompose the functions, and deploy this functionality to the physical sub-systems, hardware, software and/or firmware.
In this talk, we acknowledge the strengths of the Arcadia framework, and the benefits it brings, whilst considering the need to tailor the generic viewpoints. We will provide examples of how we have adopted the generic Arcadia framework and further specified some of the viewpoints to meet the needs of our stakeholders. We will discuss future work looking at how we can translate these specialisations across other areas of the model. Finally, we will provide some suggestions and advice on tailoring views to meet your own needs and ensuring stakeholder engagement with the model.
Using Capella on a Brazilian Nanosat Project
Discover how MBSE is used on the Brazilian CubeSat development program.
With two nano satellites already in operation (NANOSATC-BR1 and NANOSATC-BR2), the Brazilian National Institute for Space Research (INPE-MCTI) is currently in the conceptual phase of a third mission (NANOSATC-BR3).
Giulia Herdies from the Federal University of Santa Maria in Brazil, will present how the Capella tool and the Arcadia method are used in the second phase of the project, to develop the concept of this mission.
During this webinar, she explains:
-Why the use of MBSE is vital for development of the conceptual phase, by allowing a global understanding of the mission by all involved.
-How stakeholders' needs and project restrictions were broken down within the operational, functional and physical aspects, which resulted in a preliminary definition of a viable concept solution.

Systems engineering is an iterative approach traditionally applied one-way, from the definition of the user needs to the implementation of a solution that satisfies certain requirements and is constrained by cost and schedule. This presentation instead aims at exploring the educational benefits of applying the opposite practice, thus retrieving system and subsystem level requirements based on a solution already implemented and taking advantage of the MBSE possibilities to realize a model of the system according to the ARCADIA method and systems engineering approach, using the Capella MBSE Tool. This reverse-engineering process has been applied to a renowned Space mission, the ESA Mars Express satellite, whose goal is to investigate all aspects of the martian environment, including the subsurface, surface and atmosphere of the planet, in order to search for evidence of extinct or extant life. The uppermost goal of this project is to demonstrate the benefits for university students at a Master's level keen on systems engineering in implementing the Capella tool to retrieve the system architecture and the operational processes in a "reversed" strategy. In this work, students have been compelled to apply systems engineering processes to justify the design choices and exploit the already well-known missions and capabilities to build the architecture and functional chains as a starting point for the reverse engineering of the identified subsystems. The results prove it is possible, and also recommendable time-wise, to teach Space engineering and Systems engineering students by using this inverse approach, rather than the canonic one in which students have to design a whole mission from scratch.

A pattern language for microservices - June 2021
The microservice architecture is growing in popularity. It is an architectural style that structures an application as a set of loosely coupled services that are organized around business capabilities. Its goal is to enable the continuous delivery of large, complex applications. However, the microservice architecture is not a silver bullet and it has some significant drawbacks.
The goal of the microservices pattern language is to enable software developers to apply the microservice architecture effectively. It is a collection of patterns that solve architecture, design, development and operational problems. In this talk, I’ll provide an overview of the microservice architecture and describe the motivations for the pattern language. You will learn about the key patterns in the pattern language.

A pattern language for microservices - June 2021
The microservice architecture is growing in popularity. It is an architectural style that structures an application as a set of loosely coupled services that are organized around business capabilities. Its goal is to enable the continuous delivery of large, complex applications. However, the microservice architecture is not a silver bullet and it has some significant drawbacks.
The goal of the microservices pattern language is to enable software developers to apply the microservice architecture effectively. It is a collection of patterns that solve architecture, design, development and operational problems. In this talk, I’ll provide an overview of the microservice architecture and describe the motivations for the pattern language. You will learn about the key patterns in the pattern language.

Dataiku & Snowflake Meetup Berlin 2020
From the Data Work Out event:
Performant and scalable Data Science with Dataiku DSS and Snowflake
Managing the whole process of setting up a machine learning environment from end-to-end becomes significantly easier when using cloud-based technologies. The ability to provision infrastructure on demand (IaaS) solves the problem of manually requesting virtual machines. It also provides immediate access to compute resources whenever they are needed. But that still leaves the administrative overhead of managing the ML software and the platform to store and manage the data.
A fully managed end-to-end machine learning platform like Dataiku Data Science Studio (DSS) that enables data scientists, machine learning experts, and even business users to quickly build, train and host machine learning models at scale, needs to access data from many different sources and can also access data provided by Snowflake. Storing data in Snowflake has three significant advantages: a single source of truth, shorten the data preparation cycle, scale as you go.

As recently as three years ago, the cloud was viewed as a differentiator for some PLM vendors. The PLM world was divided between those who viewed the cloud as “the future” and those who viewed it as a fad. Today, most PLM vendors touch the cloud or engage with it in some way. But... what has really changed? Where do we stand with the big questions/challenges with PLM? Can the cloud still be the source of a competitive differentiator for PLM vendors?

Leveraging Alf for SysML, Part 2: More Effective Trade Study Modeling
Alf is the OMG-standard textual language specifically designed for specifying executable behavior in the context of graphical, executable UML and SysML models. It is the best alternative to using complicated activity diagrams or scripting languages not designed for use in models. Part 2 of this tutorial focuses on leveraging Alf in SysML models for studying trade-offs between design variants.
Leveraging Alf for SysML, Part 1: Better Simulation Modeling
The document discusses leveraging the Alf action language for executable modeling in SysML. It provides an overview and introduction to using Alf with SysML, including hands-on exercises to create a heating simulation model. The key topics covered include installing the Alf plugin, the basics of Alf syntax and semantics, mapping Alf to fUML, using Alf for operations, state machines, signals, and more. Hands-on steps demonstrate creating blocks, activities, and state machines with Alf code to model and execute a heating simulation.
The Very Model of a Modern Metamodeler
Philosophers have been talking about metaphysics since Aristotle. Logicians have used metalanguages for 80 years. And, in the last 50 years, computer scientists have produced metaobjects, metaclasses and metamodels. “Going meta” is now even part of the popular culture. What is this all about?
It is about the incredibly powerful human ability to reflect on what we are doing. Bringing this capability to our modeling languages, we can create languages able to express their own definitions. But, with real semantic formalization, we also open up the possibility of creating tools that can reflect on the very models they are being used to create. What might this mean for the next generation of modeling languages and tools?
This presentations goes meta, to reflect on reflection and try to figure it out.
Precise Semantics Standards at OMG: Executing on the Vision
The document discusses standards for precise semantics in executable modeling developed by the Object Management Group (OMG). It summarizes Foundational UML (fUML), the Action Language for fUML (Alf), the Precise Semantics of Composite Structure (PSCS), and the Precise Semantics of State Machines (PSSM). It outlines potential future standards and provides resources for these existing and upcoming specifications.
Model Driven Architecture without Automation

Using Alf with Cameo Simulation Toolkit - Part 2: Modeling
Alf is an OMG-standard textual language with a familiar Java-like syntax, but it is designed specifically to be used in the context of graphical, executable UML and SysML models. This language is available for use in No Magic's Cameo Simulation Toolkit (CST) v18.5 to write expressions and behaviors in executable UML. This presentation follows on from "Using Alf with Cameo Simulation Toolkit - Part 1", covering the use of Alf for specifying behaviors in models of multiple, communicating objects, including synchronous operation calling and asynchronous signal sending.
Using Alf with Cameo Simulation Toolkit - Part 1: Basics
Alf is an OMG-standard textual language with a familiar Java-like syntax, but it is designed specifically to be used in the context of graphical, executable UML and SysML models. This language is available for use in No Magic's Cameo Simulation Toolkit (CST) v18.5 to write expressions and behaviors in executable UML. Behind the scenes, Alf is actually compiled into UML activity models, which are then automatically integrated into your overall model, so they can be seamlessly executed using CST. This presentation gives an introduction to the Alf language, a tutorial on how to use it in CST and hands-on exercises to try yourself. You will be amazed at how much quicker and easier it is to write three lines of Alf code, rather than create by hand an equivalent activity model of 20 or more elements!
Programming in UML: An Introduction to fUML 1.3 and Alf 1.1
Based on a tutorial presentation given at the OMG Executable UML Information Day, this version of the presentation has been updated for fUML 1.3 and Alf 1.1, the latest versions as of this upload.
Hands On With the Alf Action Language: Making Executable Modeling Even Easier
Do you use the industry-leading model execution capabilities provided by Cameo Simulation Toolkit (CST)? Do you love being able to simulate systems using state machines and activities? But, on the other hand, do you dread the complexity of using activity diagrams to code really detailed behavior? Or do you get annoyed by having limited access your model state if you use a scripting language instead? Now there is a solution! The Alf Plugin gives you the ability to use the OMG-standard Alf action language to write expressions and behaviors in models executed using CST. Alf is a textual language with a familiar Java-like syntax, but it is designed specifically to be used in the context of graphical, executable UML and SysML models. Indeed, behind the scenes, Alf is actually compiled into UML activity models, which are then automatically integrated into your overall model, so they can be seamlessly executed using CST. This tutorial gives you an introduction to the Alf language, instruction on how to install and use the Alf Plugin with CST, and a chance to try it out hands-on. You will be amazed at how much quicker and easier it is to write three lines of Alf code, rather than create by hand an equivalent activity model of 20 or more elements!
Standards-Based Executable UML: Today's Reality and Tomorrow's Promise
This webinar demonstrates the practical realization of standards-based executable modeling in UML, showing its importance for moving forward in a number of, perhaps, unexpected areas, including agile development methods, multi-core programming and model-based system engineering. Today’s Executable UML is based on the OMG’s Foundational UML (fUML) standard, for executable object-oriented and activity modeling, and the Action Language for fUML (Alf) standard, which defines a corresponding textual representation. But this is only the beginning. Additional Executable UML standards are being built on this foundation, including recent ones for composite structure and state machines.
UML: This Time We Mean It!
This document provides an overview of the history and development of the Unified Modeling Language (UML) and Foundational UML (fUML) standard for executable modeling. It discusses how UML evolved from its origins in object-oriented analysis and design in the 1980s-1990s to add formal execution semantics definitions. fUML and the Action Language for Foundational UML (Alf) provide a computationally complete subset of UML with a defined execution model, addressing UML's previous lack of precise semantics. The document outlines the key components and implementations of fUML and Alf and their role in specifying UML's structural and behavioral semantics formally.
A Unified View of Modeling and Programming
The document discusses the unification of modeling and programming using executable UML. It argues that a program is a model of computation that is abstracted from implementation details, and that a programming language allows the creation of execution models. UML can be used for both domain modeling and executable modeling of computations through its precise execution semantics. A combined modeling/programming language should allow expression of problem and solution domain models with both formal semantics for reasoning and execution semantics for behavioral models, using both textual and graphical notations.
UML as a Programming Language
The Unified Modeling Language (UML) is, of course, a modeling language. But there are now standard, executable semantics for a subset of UML (known as Foundational UML or fUML) and a standard language that provides a textual representation for this subset (the Action Language for fUML or Alf). Doesn’t this just make at least this subset of UML into a programming language?
Well, yes. After all, a programming language is really itself a modeling language for modellng computations that can actually be executed on computation hardware. In this view, all programs are models, but only some models, the executable models, are programs. Which means that an “executable modelling language” is, by definition, a programming language.
But is this a good thing? That is the question explored in this presentation, which argues that the answer is “yes”. And, moreover, UML as a programming language may, in fact, be important for moving forward in a number of, perhaps, unexpected areas, including agile development methods and programming for multi-core architectures.
Executable UML Roadmap (as of September 2014)
The document outlines the past, present, and future of executable UML specifications. It discusses foundational UML (fUML) which defines an executable subset of UML, the Action Language for fUML (Alf) which provides a textual notation, and the Precise Semantics of UML Composite Structures (PSCS) which extends fUML for modeling composite structures. It describes open source and commercial implementations of these specifications and notes ongoing work to finalize the specifications and extend them to cover additional UML elements like state machines. The long term vision is for a suite of specifications that define the precise semantics of different aspects of UML to enable executable modeling.
Essence: A Common Ground for Flexible Methods
The document discusses Essence, a common ground for flexible software engineering methods. It provides a kernel of essential concepts and a language for defining methods and practices close to how practitioners work. The kernel includes things like activities, competencies, and states. The language allows graphically and textually defining elements like alphas (abstract progress attributes), activity spaces, and competencies. Practices can then be composed from these elements to provide guidance tailored to different contexts. An example shows defining the Scrum practice by extending elements from the kernel. The goal is a flexible yet common foundation to help practitioners across a variety of methods and experience levels.
UML: Once More with Meaning
The Unified Modeling Language (UML) has arguably succeeded in becoming the most commonly used modeling notation for software development. But “modeling” in the software community seems largely to mean simply drawing pictures, either to represent the problem domain or to blueprint a solution, without a precise enough meaning to fully specify the functionality of the system being developed. As a result, the UML standard,S up to and including UML 2.4.1, do not define the semantics of UML models at all precisely.
Nevertheless, there has also long been an interest in models that are more precise, even to the extent that they may be executed in their own right. It has taken a while for this viewpoint to penetrate into the mainstream of UML usage. But there has been in a great deal of work in recent years toward the standardization of the formal semantics of UML models – the “meaning” behind the pictures: the Foundational UML (fUML) specification adopted in 2008; the Action Language for fUML (Alf), adopted in 2010; the UML 2.5 specification (which includes a semantics conformance point for the first time); and the Precise Semantics of UML Composite Structures.
This presentation reviews the state of this work and the implications in practice of bringing real meaning to UML.
Succeeding with Agile in the Federal Government: A Coach's Perspective
The document summarizes key principles from the Agile Manifesto and provides advice for implementing Agile practices in government organizations. It discusses embracing individuals and interactions over processes; delivering working software over documentation; prioritizing customer collaboration over contract negotiation; and responding to change rather than rigidly following a plan. The document offers dos and don'ts for applying these Agile concepts when working with government agencies and contractors.
UML 2.5: Specification Simplification
A presentation on the UML 2.5 specification simplification effort, presented at the 3rd Biannual Workshop on Eclipse Open Source Software and OMG Open Specifications.
Models, Programs and Executable UML
1. All programs are models that specify computations to be executed on a computer, with programming languages serving as modeling languages.
2. Executable UML models are programs because UML 2 has constructs that allow specification of Turing-complete computation models with precise execution semantics.
3. Executable UML models are useful because they can be tested like programs without needing to be recoded, instead being compiled from models at a higher level of abstraction.
Programming in UML: An Introduction to fUML and Alf
The document discusses programming in UML using the Foundational UML (fUML) standard and the Action Language for fUML (Alf). It provides an overview of fUML and Alf, which define an executable subset of UML and a textual action language for specifying behaviors in UML models. The document uses a motivating example of an e-commerce ordering system to illustrate key concepts of executable UML including activities, actions, structure, and asynchronous communication.

Prediction of Electrical Energy Efficiency Using Information on Consumer's Ac...
Energy efficiency has been important since the latter part of the last century. The main object of this survey is to determine the energy efficiency knowledge among consumers. Two separate districts in Bangladesh are selected to conduct the survey on households and showrooms about the energy and seller also. The survey uses the data to find some regression equations from which it is easy to predict energy efficiency knowledge. The data is analyzed and calculated based on five important criteria. The initial target was to find some factors that help predict a person's energy efficiency knowledge. From the survey, it is found that the energy efficiency awareness among the people of our country is very low. Relationships between household energy use behaviors are estimated using a unique dataset of about 40 households and 20 showrooms in Bangladesh's Chapainawabganj and Bagerhat districts. Knowledge of energy consumption and energy efficiency technology options is found to be associated with household use of energy conservation practices. Household characteristics also influence household energy use behavior. Younger household cohorts are more likely to adopt energy-efficient technologies and energy conservation practices and place primary importance on energy saving for environmental reasons. Education also influences attitudes toward energy conservation in Bangladesh. Low-education households indicate they primarily save electricity for the environment while high-education households indicate they are motivated by environmental concerns.

Bituminous road construction project based learning report
Road construction is not as easy as it seems to be, it includes various steps and it starts with its designing and
structure including the traffic volume consideration. Then base layer is done by bulldozers and levelers and after
base surface coating has to be done. For giving road a smooth surface with flexibility, Asphalt concrete is used.
Asphalt requires an aggregate sub base material layer, and then a base layer to be put into first place. Asphalt road
construction is formulated to support the heavy traffic load and climatic conditions. It is 100% recyclable and
saving non renewable natural resources.
With the advancement of technology, Asphalt technology gives assurance about the good drainage system and with
skid resistance it can be used where safety is necessary such as outsidethe schools.
The largest use of Asphalt is for making asphalt concrete for road surfaces. It is widely used in airports around the
world due to the sturdiness and ability to be repaired quickly, it is widely used for runways dedicated to aircraft
landing and taking off. Asphalt is normally stored and transported at 150’C or 300’F temperature
A high-Speed Communication System is based on the Design of a Bi-NoC Router, ...
The Network on Chip (NoC) has emerged as an effective
solution for intercommunication infrastructure within System on
Chip (SoC) designs, overcoming the limitations of traditional
methods that face significant bottlenecks. However, the complexity
of NoC design presents numerous challenges related to
performance metrics such as scalability, latency, power
consumption, and signal integrity. This project addresses the
issues within the router's memory unit and proposes an enhanced
memory structure. To achieve efficient data transfer, FIFO buffers
are implemented in distributed RAM and virtual channels for
FPGA-based NoC. The project introduces advanced FIFO-based
memory units within the NoC router, assessing their performance
in a Bi-directional NoC (Bi-NoC) configuration. The primary
objective is to reduce the router's workload while enhancing the
FIFO internal structure. To further improve data transfer speed,
a Bi-NoC with a self-configurable intercommunication channel is
suggested. Simulation and synthesis results demonstrate
guaranteed throughput, predictable latency, and equitable
network access, showing significant improvement over previous
designs

Accident detection system project report.pdf
The Rapid growth of technology and infrastructure has made our lives easier. The
advent of technology has also increased the traffic hazards and the road accidents take place
frequently which causes huge loss of life and property because of the poor emergency facilities.
Many lives could have been saved if emergency service could get accident information and
reach in time. Our project will provide an optimum solution to this draw back. A piezo electric
sensor can be used as a crash or rollover detector of the vehicle during and after a crash. With
signals from a piezo electric sensor, a severe accident can be recognized. According to this
project when a vehicle meets with an accident immediately piezo electric sensor will detect the
signal or if a car rolls over. Then with the help of GSM module and GPS module, the location
will be sent to the emergency contact. Then after conforming the location necessary action will
be taken. If the person meets with a small accident or if there is no serious threat to anyone’s
life, then the alert message can be terminated by the driver by a switch provided in order to
avoid wasting the valuable time of the medical rescue team.
