This document discusses reducing energy usage in homes in a low-cost and effective manner. It states that energy usage in homes is expensive due to too much energy being used. A low-cost solution is needed to reduce household energy usage and costs. The proposed solution is to promote knowledge and education to architects, engineers, and the public to design homes that use energy asymmetrically by taking advantage of sunlight and natural wind. This can be helped by using appliances that periodically and automatically turn on and off through mechanical means, substituting human error and reducing unnecessary energy usage.

Sprinkler myths and facts
Fires in homes pose a major threat, as fires caused over 3,000 civilian deaths in 2013, with 83% occurring in homes. All model safety codes require fire sprinklers in new home construction as they are proven to effectively protect lives and property from fires. Sprinklers control fires and may extinguish them before firefighters arrive. They typically only activate the sprinkler nearest the fire, leaving the rest of the home dry. Sprinklers significantly reduce property damage and the risk of dying in a home fire.

Dandelion Hashtable: beyond billion requests per second on a commodity server
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

The typical problem in product engineering is not bad strategy, so much as “no strategy”. This leads to confusion, lack of motivation, and incoherent action. The next time you look for a strategy and find an empty space, instead of waiting for it to be filled, I will show you how to fill it in yourself. If you’re wrong, it forces a correction. If you’re right, it helps create focus. I’ll share how I’ve approached this in the past, both what works and lessons for what didn’t work so well.

Chris Jones, Director of Product Management at BrainChip , presents the “Temporal Event Neural Networks: A More Efficient Alternative to the Transformer” tutorial at the May 2024 Embedded Vision Summit.
The expansion of AI services necessitates enhanced computational capabilities on edge devices. Temporal Event Neural Networks (TENNs), developed by BrainChip, represent a novel and highly efficient state-space network. TENNs demonstrate exceptional proficiency in handling multi-dimensional streaming data, facilitating advancements in object detection, action recognition, speech enhancement and language model/sequence generation. Through the utilization of polynomial-based continuous convolutions, TENNs streamline models, expedite training processes and significantly diminish memory requirements, achieving notable reductions of up to 50x in parameters and 5,000x in energy consumption compared to prevailing methodologies like transformers.
Integration with BrainChip’s Akida neuromorphic hardware IP further enhances TENNs’ capabilities, enabling the realization of highly capable, portable and passively cooled edge devices. This presentation delves into the technical innovations underlying TENNs, presents real-world benchmarks, and elucidates how this cutting-edge approach is positioned to revolutionize edge AI across diverse applications.Crafting Excellence: A Comprehensive Guide to iOS Mobile App Development Serv...

From Natural Language to Structured Solr Queries using LLMs
This talk draws on experimentation to enable AI applications with Solr. One important use case is to use AI for better accessibility and discoverability of the data: while User eXperience techniques, lexical search improvements, and data harmonization can take organizations to a good level of accessibility, a structural (or “cognitive” gap) remains between the data user needs and the data producer constraints.
That is where AI – and most importantly, Natural Language Processing and Large Language Model techniques – could make a difference. This natural language, conversational engine could facilitate access and usage of the data leveraging the semantics of any data source.
The objective of the presentation is to propose a technical approach and a way forward to achieve this goal.
The key concept is to enable users to express their search queries in natural language, which the LLM then enriches, interprets, and translates into structured queries based on the Solr index’s metadata.
This approach leverages the LLM’s ability to understand the nuances of natural language and the structure of documents within Apache Solr.
The LLM acts as an intermediary agent, offering a transparent experience to users automatically and potentially uncovering relevant documents that conventional search methods might overlook. The presentation will include the results of this experimental work, lessons learned, best practices, and the scope of future work that should improve the approach and make it production-ready.

- 2. 2 As energy usage becomes more acute and expensive, there are many efforts to reduce its usage cost especially in the home. If you consider a typical house, how would you reduce energy usage if you are cost constrained i.e. the solution needs to be low cost yet effective. PROBLEM DESCRIPTIO N PART 1
- 3. 3 PROBLEM STATEMENT BENEFIT S Energy in homes are expensive, the main reason for this is too much energy usage. A low cost solution to reduce energy usage in home needs to be found. There will be a significant reduction in overall household costs, energy usage and heat emission. PROCESS FLOW
- 4. 4 CAUSE & EFFECT CHAIN ANALYSIS Lack of Education/ Knowledge
- 5. 5 ENGINEERING CONTRADICTION If proper education/ knowledge is offered, then energy awareness increases, but this will incur higher cost and more time for its successful implementation. Improving Parameter Worsening Parameter #24 Loss of Information #22 Loss of Energy #27 Reliability #25 Loss of Time #33 Ease of Operation (Manufacturability) NARROWED INVENTIVE PRINCIPLES
- 6. 6 PROPOSED SOLUTION #10 Prior Action: Appliances with prior built-in technology to save energy. E.g: auto “on” and “off” sensor. #19 Periodic Action: Periodic Reminders, Transition from Analog to Digital Control, periodic “on” and “off”. #28 Mechanical Substitution: Auto “on” and “off” instead of relying on human “clumsiness”. E.g: Feedback control circuitry. #4 Asymmetry: Asymmetric home designs + renewable energy.
- 7. 7 FINAL SOLUTION (Prior Action, Periodic Action, Mechanical Substitution, Asymmetry) Knowledge/ Education should be promoted to architects, engineers and public to have homes with asymmetric (non- conventional) usage of energy, by making full use of sunlight in bright hours of the day, using natural wind from the environment. This can be helped by prior knowledge in building and using modern electrical appliances that substitute human carelessness by periodically and automatically turning “off” and “on” unused and idling electrical appliances substituting mechanical means of human reliability.
