Anomalous Detection for High-Frequency Electricity Consumption DataWeiling Kang
Over-consumption of electrical energy has been a growing concern worldwide. Energy waste incurs not only economic issues but also severe environmental concerns, such as light pollution and increased carbon emissions. Therefore, the goal of our project is to enable the households to understand their electricity consumption behavior and to be aware of unexpected power consumption value through the means of training energy usage dataset with Auto ARIMA, SARIMA (seasonal autoregressive integrated moving average) and RNN (recurrent neural network) machine learning models. We believe effective energy consumption feedback mechanism can reduce energy consumption, help economic savings and achieve sustainability.

The electric power sector is poised for transformative changes. The growing penetration of distributed energy resources, including distributed generation such as solar PV or fuel cells, electric vehicles, stationary batteries, and demand response, could remake electricity markets, power system operations, and utility business models alike. Regulators, utilities, and new technology companies are now positioning themselves for a new era of electricity innovation. What will the utility sector of the future look like? Who will deliver electricity services a decade or two from now? Who is best positioned to grow market share and capture new market opportunities? Will energy consumers benefit from a more distributed power system?
Energy efficiency in synchronous single-phase motors 220 (VAC) - 50 (Hz) PMSM...Ibar Federico Anderson
Taking into account the importance of the Energy Efficiency (EE), especially the one referring to the single-phase electric power, of domiciliary and commercial consumption. The problem of the environmental impact (carbon footprint) that is being generated, means an opportunity for the development of more efficient products in the consumption of electric energy (final objective). In clear orientation with this ethical line of Dis. Ind., We worked with our own Ecodesing methodology, focused on the fifth stage of life cycle analysis (LCA): efficient use of electric energy. The purpose was to develop a synchronous motor of type PMSM of 220 (volts), 50 (Hz) of alternating current (AC); to be used in fans, air conditioners and other cooling systems: air forcers, etcetera. The main result obtained was the reduction of 52% of the active power (W), without loss of speed (revolutions per minute) of the blades. As a final conclusion we can say that there was a saving of 58% consumption of active electric power (kWh).

PhD: Self-Forecasting Energy Load Stakeholders for Smart Grids Ilic Dejan 2014Dejan Ilic
The unpredictability of energy loads is responsible for a significant portion of efficiency loss in power grids. Today, we are not only facing uncertainties in consumer loads, but increasing adoption of renewable energy production is also affecting producers. In order to reduce load uncertainties, emerging Smart Grid business models call for the active participation of traditionally passive stakeholders, such as office buildings or even residential consumers. These models include, for instance, active involvement in grid operations, participation in local energy markets, demand response programs, etc. Still, many of these require stakeholders to make accurate load forecasts, which is hard to achieve on small scales.
To overcome this obstacle, this work introduces the concept of variable energy storage where assets of stakeholders, such as electric vehicles, are used to improve accuracy by absorbing errors of their self-forecasts. Since accuracy as such is achieved internally, by reporting the self-forecast to external parties a deterministic energy signature is achieved. The challenges of this dissertation are to (1) enable an efficient communication in between stakeholders, (2) reach sufficient forecast accuracy of an individual or a small group of consumers, and to (3) build a system that enables the deterministic behaviour of self-forecasting stakeholders. This work addresses these challenges and evaluates proposed solutions on real world cases. The combined contribution enables self-forecasting energy load stakeholders whose deterministic load behaviour make them reliable resources that can greatly benefit themselves and other stakeholders. Equally as important, deviation from their predicted loads can be measured and intentional load changes can be verified, solving one of the great problems of incentivizing in Smart Grids.

Energy Science Engineering and management systemkeshavmech2008
Energy management includes planning and operation of energy production and energy consumption units as well as energy distribution and storage. Objectives are resource conservation, climate protection and cost savings, while the users have permanent access to the energy they need. It is connected closely to environmental management, production management, logistics and other established business functions. The VDI-Guideline 4602 released a definition which includes the economic dimension: "Energy management is the proactive, organized and systematic coordination of procurement, conversion, distribution and use of energy to meet the requirements, taking into account environmental and economic objectives".[1] It is a systematic endeavor to optimize energy efficiency for specific political, economic, and environmental objectives through Engineering and Management techniques.[2]
Energy efficiency
Base line of energy assessment
One of the initial steps for an effective energy cost control program is the base line energy assessment, which examines the pattern of existing energy usage by the government or any sub-entity of the government or private organization. This program will set the reference point for improvements in energy efficiency. Energy efficiency can improve the existing energy usage and benchmarking of every individual section such as area, sub-area and the industry etc. .
Organizational integration
It is important to integrate the energy management in the organizational structure, so that the energy management can be implemented. Responsibilities and the interaction of the decision makers should be regularized. The delegation of functions and competencies extend from the top management to the executive worker. Furthermore, a comprehensive coordination can ensure the fulfillment of the tasks.
It is advisable to establish a separate organizational unit "energy management" in large or energy-intensive companies. This unit supports the senior management and keeps track. It depends on the basic form of the organizational structure, where this unit is connected. In case of a functional organization the unit is located directly between the first (CEO) and the second hierarchical level (corporate functions such as production, procurement, marketing). In a divisional organization, there should be a central and several sector-specific energy management units. So the diverse needs of the individual sectors and the coordination between the branches and the head office can be fulfilled. In a matrix organization the energy management can be included as a matrix function and thus approach most functions directly.
Energy management in operational functions
Facility management
Facility management is an important part of energy management, because a huge proportion (average 25 per cent) of complete operating costs are energy costs. According to the International Facility Management Association (IFMA), facility management is "a profession that encompass
An over view of the maturing of Energy Management from an ad hoc practice to a defined Systems Engineering Practice. Examples of method, planning, earned value management, and metrics are included.

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.
Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

2. Why Should Tourism Care about Energy?
• According to the EPA, an average hotel spends $2,196 per available
room each year on energy
• According to Pacific Gas and Electric's Food Service Technology
Center, the commercial food service sector wastes $8 billion on
inefficient cooking, holding and storage
• According to the US Energy Information Administration, commercial
electricity prices have risen about 40% between 1999 and 2009
• Lodging and food
service are two of the
biggest users of energy

3. Step One: Developing an Energy Plan
Assemble “Energy Team”
responsible for and passionate
about saving:
energy/environment/costs
Evaluate Analyze
blow your own horn!- what needs what type of systems do you use,
more work? what opportunities are there
Execute Prioritize
be proactive and actually pull the best ‘bang for buck’, which are
trigger most important
4. Energy in the Tourism Industry
Where does all that energy go?
Source: EPA Hotel Energy Use Profile
Source: A Profile of Energy Use In Restaurants
5. Calculating Energy Costs of an Appliance:
To calculate how much an appliance would cost to
operate per year:
1. Appliance’s wattage multiplied by the # of hours used per day
multiplied the # of days used per year
2. Divide the by 1,000 to get the number of kilowatt-hours used
annually
3. Then multiple the number of kilowatt-hours by your electricity
rate in $/kilowatt-hour (typically around $0.08 per kWh)
Step #1
Lamp with three 60 watts bulbs X 10 hours/day X 300 days a year = 540000 Wh/year
Step #2
900000 Wh/year ÷ 1000 Wh/kWh = 540 kWh/year
Step #3
9 kWh/year X 0.08 $/kWh = $43 a year
6. Energy Audits and Paybacks:
• An analysis or inspection of energy flows within a
building or a process
•Conducted to identify
• Where improvements can be made
• Establish baselines compare with industry standards and
measure success of future efforts
