Graphical System Design Guide to Power Electronics Co-Simulation ...

Updated, 11/1/2011 This is a guide to power electronics demonstration samples for Multisim/LabVIEW co-simulation. These new tools are intended to enable desktop development of power electronics control IP for LabVIEW FPGA, enabling you to develop/test/debug/validate before you compile to physical hardware. By exploring these samples, you can learn basic features of the co-simulation environment as well as the techniques you will need to accurately simulate LabVIEW FPGA control systems with your power electronics circuits. By exploring the samples and suggested exercises in this document with live interactive LabVIEW front panels, you can also enhance your intuitive understanding of the switch mode power electronics circuits and control systems. The goal of these graphical system design tools is to significantly accelerate the development of inverter control systems, by enabling you to develop your exact deployment code on the desktop (without long FPGA compiles), and using formal software verification techniques (build each IP block to specification and perform functional verification testing on the desktop whenever changes or updates are made). NI hopes the new tools will serve as a catalyst and platform for innovation and creativity and would like to invite you to expand and enhance the samples contained in this guide. We encourage you to develop, document and share through the online Power Electronics Development Center community site the following: 1. Power electronics circuit examples, 2. Power electronics control algorithms for LabVIEW FPGA, 3. Multisim power electronics component models, 4. Comparisons between physical test data and simulation results, and 5. Training materials or curriculum for industry professionals or university students. In some cases, you may be able to negotiate discounted access to the NI hardware and software tools to reward and encourage the development and sharing of valuable material for the power electronics developer community. Please email proposals to NI Clean Energy Product Manager, Brian.MacCleery@ni.com.

An Ontological Approach to Business Process Modeling

Business people use informal methods to represent business processes (BP), having the main objective to support an enterprise organization. On the other hand, application software is increasingly based on Service Oriented Architectures, where the application logic is represented by executable BP (e.g., by using BPEL.) Despite both are aiming at BP modelling, the methods used by business people and IT specialists are quite different. The former use informal, descriptive methods, with an intuitive semantics difficult to be translated to the formal representation needed in the IT world. This paper presents the main lines of an ontological framework for the representation of BP semantics: BPAL (Business Process Abstract Language.) It is primarily conceived to provide a formal semantics to BPMN, an informal BP modelling method that is emerging in the business world. The modelling categories of BPAL are based on well accepted business notions, such as activity, decision, role. We believe that it may be useful beyond BPMN, in more general business contexts. BPAL is an abstract language (no drawing symbols are provided) having a procedural semantics (allowing a translation to an executable form, BPEL), and a declarative semantics, to be processed by an inference engine.

Measuring Similarity between Business Process Models - Mendling

Quality aspects become increasingly important when business process modeling is used in a large-scale enterprise setting. In order to facilitate a storage without redundancy and an efficient retrieval of relevant process models in model databases it is required to develop a theoretical understanding of how a degree of behavioral similarity can be defined. In this paper we address this challenge in a novel way. We use causal footprints as an abstract representation of the behavior captured by a process model, since they allow us to compare models defined in both formal modeling languages like Petri nets and informal ones like EPCs. Based on the causal footprint derived from two models we calculate their similarity based on the established vector space model from information retrieval. We validate this concept with an experiment using the SAP Reference Model and an implementation in the ProM framework. Keywords: Business Process Modeling, Event-driven Process Chains, Similarity, Equivalence.

BIM 101—Basics of BIM BIM 102—Advanced Navisworks Training

Monday, October 14, 2013 8:00 a.m. — 12:00 p.m. The Basics of BIM Chapter Education Program is designed specifically for SMACNA Contractors who are eager to learn the essential concepts of BIM. This course will benefit Contractors without any formal CAD experience, as well as Contractors versed in 3D CAD, but may not have performed in the BIM arena. This half-day course is designed to give an overview of BIM to prepare SMACNA contractors for involvement in BIM related projects. Some of the key takeaways from this course will be to define BIM as it relates to SMACNA Contractors, discuss the past, present, and future of BIM, and identify the hardware and software costs for implementation.

UNDERSTANDING FURNITURE STYLES Chapter 20

CHANGING STYLES How Styles are Identified …  Some furniture styles are identified by the person who originated the design  Some furniture styles are identified by the general design movement of the time  Some furniture styles are identified by the era in which they were first made. – Called “Period Pieces” – Often named for the king or queen who was in power during that time Classic and Fads  Classics – Stand the test of time; now in museums or collector’s homes; replicas created  Fads – Come in and out; some fads never return WHY DESIGNS CHANGE Several reasons … available materials, methods of manufacturing, changes in lifestyle, tastes Materials and Manufacturing  Modern synthetic materials have different properties than traditional wood, thereby creating potential for new designs. – Example – Wood chairs are carved while some plastic chairs may be molded from liquid plastic.  As new materials are developed, furniture makers experiment with different processes to develop new furniture. WHY DESIGNS CHANGE Lifestyle Changes  Designs often reflect the time during which the pieces were made and the lifestyles of the people who used the furniture. • Example – 18th century in France and England … much of the furniture was formal and elegant, reflecting the lifestyle of the royal courts. • Example – Early colonialist of the New World … much plainer and informal.
