The document describes the 4MD model used by EPE to forecast distributed generation adoption in Brazil. The 4MD model uses a Bass diffusion model approach to project the number of adopters of technologies like PV, wind, and thermal by sector. It estimates the potential market size, then defines adoption rates based on innovation and imitation parameters estimated from historical data. Finally, it distributes projected adopters between technologies based on resource potential and historical shares to estimate installed capacity and generation. The model provides forecasts at a high geographic resolution to help assess policy impacts through 2050.

This webinar will address the key drivers of the PV market and industry in the coming years based on the Trends 2020. Gaëtan Masson, Operating Agent of IEA PVPS Task 1, will look at the past developments and future scenarios, from a global market development point of view to some key price evolution features. From social aspects of PV, collective and decentralised self-consumption policies to floating PV, this webinar will browse the global landscape of PV development.
Izumi Kaizuka, deputy chair of the IEA PVPS Task 1, will present the trends of the PV Industry. The production of polysilicon, ingots, wafers, PV cells and modules have been growing with the growth of the PV market. The gap between manufacturing capacity of PV module and the demand contributed to the recent price reduction thus resulted in lower LCOE of PV power. Across the value chain, the PV upstream sector makes efforts to improve efficiency, output and reliability. Further progress of cost reduction is expected. In the downstream sector, players are also applying various methods to reduce LCOE.

Innovation technology questions1 Explain how computer-aided .docxjaggernaoma
Innovation technology questions
1 Explain how computer-aided design and flexible manufacturing technologies help create small niches in the market place. Provide an example to illustrate your answer
Answer: Computer-aided design and flexible manufacturing help create small niches in the marketplace by allowing firms to develop and produce a greater number of versions of their products. This means that companies can now tailor their offerings to small niches in the marketplace. For example, in 2012, Toyota offered 16 different passenger vehicle lines under the Toyota brand (e.g., Camry, Prius, Highlander, and Tundra). Within each of the vehicle lines, Toyota also offered several different models (e.g., Camry L, Camry LE, Camry SE) with different features and at different price points. Students’ answers will vary.

2At a retreat by the Cleveland City Council, community leaders held a discussion on attracting and developing new businesses and increasing employment rates in the city. One leader suggested that the city should consider sponsoring a business incubator. Explain what an incubator is and how this might help the city meet its goals. What other ideas should be considered
Answer: An incubator is an institution designed to nurture the development of new businesses that might otherwise lack access to funding or advice. It allows companies to share costs and resources until they can stand on their own. If an incubator were started in Salisbury, it would help new businesses to grow and prosper. These businesses could then move out to locations of their own and hire local residents as employees. The city would not have to offer tax breaks or compete with other cities for the location of existing companies, but would be growing their own businesses.

3 How can the s-curves be used as a prescriptive tool? What would be the limitations of this approach?
Answer: Managers can use the s-curve model as a tool for predicting when a technology will reach its limits and as a prescriptive guide for whether and when the firm should move to a new, more radical technology. Firms can use data on the investment and performance of their own technologies, or data on the overall industry investment in a technology and the average performance achieved by multiple producers. Managers could then use these curves to assess whether a technology appears to be approaching its limits or to identify new technologies that might be emerging on s-curves that will intersect the firm’s technology s-curve. Managers could then switch s-curves by acquiring or developing the new technology.
However, there are many limitations to doing this. First, it is rare that the true limits of a technology are known in advance, and there is often considerable disagreement among firms about what a technology’s limits will be. Second, the shape of a technology’s s-curve is not set in stone. Unexpected changes in the market, component technologies, or complementary techno.

In software engineering, the right architecture is essential for robust, scalable platforms. Wix has undergone a pivotal shift from event sourcing to a CRUD-based model for its microservices. This talk will chart the course of this pivotal journey.
Event sourcing, which records state changes as immutable events, provided robust auditing and "time travel" debugging for Wix Stores' microservices. Despite its benefits, the complexity it introduced in state management slowed development. Wix responded by adopting a simpler, unified CRUD model. This talk will explore the challenges of event sourcing and the advantages of Wix's new "CRUD on steroids" approach, which streamlines API integration and domain event management while preserving data integrity and system resilience.
Participants will gain valuable insights into Wix's strategies for ensuring atomicity in database updates and event production, as well as caching, materialization, and performance optimization techniques within a distributed system.
Join us to discover how Wix has mastered the art of balancing simplicity and extensibility, and learn how the re-adoption of the modest CRUD has turbocharged their development velocity, resilience, and scalability in a high-growth environment.

Providing Globus Services to Users of JASMIN for Environmental Data AnalysisGlobus
JASMIN is the UK’s high-performance data analysis platform for environmental science, operated by STFC on behalf of the UK Natural Environment Research Council (NERC). In addition to its role in hosting the CEDA Archive (NERC’s long-term repository for climate, atmospheric science & Earth observation data in the UK), JASMIN provides a collaborative platform to a community of around 2,000 scientists in the UK and beyond, providing nearly 400 environmental science projects with working space, compute resources and tools to facilitate their work. High-performance data transfer into and out of JASMIN has always been a key feature, with many scientists bringing model outputs from supercomputers elsewhere in the UK, to analyse against observational or other model data in the CEDA Archive. A growing number of JASMIN users are now realising the benefits of using the Globus service to provide reliable and efficient data movement and other tasks in this and other contexts. Further use cases involve long-distance (intercontinental) transfers to and from JASMIN, and collecting results from a mobile atmospheric radar system, pushing data to JASMIN via a lightweight Globus deployment. We provide details of how Globus fits into our current infrastructure, our experience of the recent migration to GCSv5.4, and of our interest in developing use of the wider ecosystem of Globus services for the benefit of our user community.
First Steps with Globus Compute Multi-User EndpointsGlobus
In this presentation we will share our experiences around getting started with the Globus Compute multi-user endpoint. Working with the Pharmacology group at the University of Auckland, we have previously written an application using Globus Compute that can offload computationally expensive steps in the researcher's workflows, which they wish to manage from their familiar Windows environments, onto the NeSI (New Zealand eScience Infrastructure) cluster. Some of the challenges we have encountered were that each researcher had to set up and manage their own single-user globus compute endpoint and that the workloads had varying resource requirements (CPUs, memory and wall time) between different runs. We hope that the multi-user endpoint will help to address these challenges and share an update on our progress here.
