In the last decade, neuro-energetics has become an important research topic, which can contribute to better understanding and interpreting brain imaging data. We need to understand how the brain encodes information coming from the environment, and how this information is converted to knowledge and meaning useful for intentional action and decision making. Valuable information can be derived from both single neuron and population (neuropil) recording in order to investigate the cognitive cycle. Usually pulses are measured with electrodes placed intracellularly while oscillations are measured through ECoG. Our main interest here is to investigate the relationship between the creation of knowledge and meaning and the metabolic cycle in neural populations, as well as the conversion of incoming action potentials to the dendritic structure of the neuron into currents which will contribute to new action potentials. This process we call the pulse-wave-pulse conversion. We model the coupling the energy consumption associated with new action potentials and the metabolic cycle, and the conclusions for future large-scale neuro-energetic models.

5. Integration – Why?•  Business applications rarely live in isolation.•  Users expect instant access to all business functions anenterprise can offer.•  Functionality may reside in different systems.•  Requires disparate applications to be connected into a larger,integrated solution.
6. Integration – How?•  Architecting integration solutions is a complex task.•  There are many conflicting drivers and even more possible rightsolutions.•  No “cookbook” for enterprise integration solutions.•  Asynchronous messaging architectures have proven to be thebest strategy for enterprise integration because they allow for aloosely coupled solution that overcomes the limitations ofremote communication, such as latency and unreliability.
7. Why Patterns?Patterns are an excellent way to ensure:1.  Everyone understands the model taken – poses a designproblem and presents a solution2.  Common vocabulary3.  Use of best practices – experience base that architects havegained by repeatedly building solutions and learning frommistakes.4.  Faster development time – reuse of patterns and not reinventpatterns

9. Enterprise Integration Patternshttp://www.eaipatterns.com/”The core language of EAI, defined in thebook Enterprise Integration Patterns byGregor Hohpe and Bobby Woolf, is also thecore language of defining ESB flows andorchestrations, as seen in the ESBsdeveloper tooling.”
10. Enterprise Integration Patterns§  EIPs are patterns using asynchronous messaging as the styleof integration.§  They are technology-agnostic which means it does not matterwhat programming language or operating system you use.§  Categorization of Patterns•  Messaging Channels•  Message Constructions•  Message Routing•  Message Transformation•  Messaging Endpoints•  System Management
11. WSO2 ESB is…•  A lightweight, high performance ESB•  Feature rich and standards compliant•  SOAP and WS-* standards•  REST support•  Domain specific protocol support (eg: FIX)•  User friendly and highly extensible•  100% free and open source with commercial support
12. WSO2 ESB – Functional Components•  Mediators•  Sequences•  Endpoints•  Proxy Services•  Event Sources•  Priority Executors•  Message Stores•  Tasks•  Local Entries•  Registry
13. More on Functional Components•  Each functional component serves a specificpurpose•  Functional components can be mixed andmatched to implement various integrationscenarios and patterns•  Configuring WSO2 ESB for a given scenariorequires:•  Identifying the right set of components•  Putting them together in the optimal manner
14. Mediatorshttp://docs.wso2.org/wiki/display/ESB460/MediatorsRich mediator library, wherein most cases a singlemediator can be directly mapped to an EIP.
