The document discusses Model-driven Architecture building for constrained systems using the ARCADIA method. ARCADIA is a model-based architecture engineering approach that starts from standards like DoDAF and IEEE 1471, and integrates and enriches them with additional viewpoints and non-functional analysis capabilities. It allows collaborative validation of architectures through standards. The method involves formalizing and sharing operational and system needs models, and then developing logical and physical architecture models. These models can then be automatically analyzed using multiple viewpoints like safety, performance, and cost to validate and optimize the solution architecture.
This document discusses business analysis methodologies and frameworks. It defines a methodology as describing who performs what tasks using what inputs to produce what outputs, when, how, and why. A framework is described as a partially completed solution with options for completion. The document outlines the Unified Methodology Architecture (UMA) components of roles, tasks, inputs, outputs, processes, and guidance. It presents a business analysis framework that maps requirements from business objectives to technical requirements. Finally, it discusses how methodologies and frameworks can be customized based on factors like competency levels and technique complexity.
This document proposes a formal approach to constructing process views from non-well-structured BPMN processes. It defines key BPMN elements and how they relate in a process. Rules are defined to regulate view generation while ensuring structural and behavioral consistency. An algorithm is developed to find the minimal set of elements to aggregate for a given user-specified set. This approach allows selective aggregation of branches and considers events and exceptions in the aggregation.
The document discusses managing federal agencies during turbulent times using an enterprise architecture approach. It states that federal agencies now need to focus on performance, customers, and high-value services to meet new standards. An enterprise architecture implements an operations concept and strategy tied to the agency's mission through defined releases. Each release provides new capabilities while integrating components to keep the enterprise functioning, with information systems development keeping pace with business changes.
Ever wonder what a robust, well-formed and fully articulated methodology should look like? We've used our Methodology Framework to provide you an real-world (and free!) example.

Compliance by Design for Artifact-Centric Business ProcessesUniversität Rostock
This document discusses an approach called "compliance by design" for ensuring that artifact-centric business processes are compliant with regulations. It involves:
1) Specifying a business process model, artifacts, agents, locations and goals
2) Translating legal texts into compliance rules
3) Modeling the compliance rules and integrating them with the business process model
4) Using tools to generate a compliant business process model that satisfies both behavioral and compliance requirements.
This approach aims to avoid subsequent proofs of compliance by building compliance into the design from the start. It also allows flexibility to change compliance rules without needing to regenerate the entire process model.
LoLA is an explicit-state model checker for Petri nets that focuses on standard properties and uses many reduction techniques such as stubborn sets, symmetries, and sweep-line heuristics to efficiently analyze large state spaces. It takes Petri nets as input in the form of place/transition nets or high-level algebraic nets and allows users to specify verification tasks involving properties such as boundedness, reachability, and temporal logics. LoLA is open source and has been used in several case studies to generate experimental results tables exploring the impact of basic design decisions.
The document describes various techniques for implementing a Petri net state space search:
1. It discusses how transitions are fired and states are evaluated by marking changed places and checking enabled transitions.
2. State predicates are stored in negation-free normal form to efficiently check state properties.
3. The state space is managed by representing states as bit vectors and organizing them in a decision tree for fast lookup and insertion.
4. Search organization involves firing transitions, finding/inserting states, and backtracking with a search stack and write-only memory approach.
This document discusses integrating the LoLA model checker as a web service for verifying Petri net properties. It lists soundness checks that LoLA can perform, including classical, weak, and relaxed soundness. It provides URLs for editing Petri nets in Oryx and calling the LoLA web service from the University of Rostock service technology site to verify properties by translating nets from PNML to LoLA format and running LoLA as a system call.
Niels Lohmann explores several case studies applying symbolic systems biology techniques:
1) Analyzing biochemical reaction chains using the tool LoLA for fast reachability queries.
2) Finding hazards in Globally Asynchronous Locally Synchronous (GALS) circuits design using Petri nets and partial order reduction.
3) Verifying service choreographies for deadlocks by translating models to open workflow nets and discovering a design flaw.
LoLA is a tool for verifying properties of Petri nets. This document discusses how to:
1. Choose and manage LoLA configurations to optimally verify properties.
2. Ask the right verification questions in a specific, modular way to efficiently verify properties.
3. Optimize Petri net modeling to take advantage of LoLA's reduction techniques and scale verification.
4. Employ scripts and makefiles to automate calling LoLA and analyzing results.
5. Integrate calling LoLA from other tools using UNIX streams for modular verification.
The document summarizes the stubborn set method for state space reduction in Petri nets. It explains that the method works by defining a stubborn set of transitions in each marking that can fire independently of transitions outside the set. This allows reducing the state space by only exploring firings within each stubborn set, while still preserving properties like deadlocks. The proof for deadlock preservation is also outlined.
LoLA is an open source tool for verifying properties of Petri nets through explicit state space generation. It features many state space reduction techniques and can verify standard properties like boundedness, reachability, and LTL/CTL formulas. LoLA was created to generate experimental results tables and explore basic design decisions like having no GUI and generating a dedicated state space for each property. It has been under development since 1998 and is aimed at helping users verify realistic models efficiently.
The document describes the input language for the LoLA model checker. It allows specifying Petri nets and verification tasks in a high-level algebraic style. Key elements include:
1. Defining sorts, operations, and their interpretations to specify the types and functions used.
2. Declaring high-level places and markings as terms over sorts to represent multiple low-level places and tokens.
3. Specifying high-level transitions as procedures with guards and input/output terms to represent multiple low-level transitions.
4. Providing verification tasks as logical formulas involving state predicates to check properties over the unfolded net.
The document discusses applying counterexample guided abstraction refinement (CEGAR) to verifying properties of Petri nets. It summarizes using the Petri net state equation to represent reachable markings as solutions to a system of linear equations. It then describes using CEGAR to iteratively check solutions and refine the abstraction by adding increments when solutions are found to be infeasible. The approach is implemented in a tool called Sara which shows better performance than other tools on verification problems involving large Petri nets and parameterized systems.
This document describes a joint research project between the University of Rostock's Computer Science and Electrical Engineering departments. The project aims to develop tools and formal methods for analyzing systems and synthesizing web services for resource-constrained devices. This will be done by applying the Devices Profile for Web Services (DPWS) standard, which allows using web service technology on embedded systems and sensor networks in a way that is compatible with existing enterprise web services. The goal is to enable web service capabilities on more intelligent devices that increasingly communicate with each other.
Workshop presentation given by Niels Lohmann on February 22, 2011 in Karlsruhe, Germany at the Third Central-European Workshop on Services and their Composition (ZEUS 2011).
This document compares Petri nets and state spaces for modeling and verification. It discusses that state spaces allow modeling global state changes over time, while Petri nets consider asynchronous components and causality of events. The document also describes techniques for efficient state space generation from Petri nets, such as checking enabled transitions with constant time, firing transitions with constant effort, backtracking transitions, and storing markings in a set. Reduction techniques like linear algebra, sweep-line methods, symmetries, and stubborn sets are also covered to reduce the state space.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UPRAHUL
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.
