Ricardo Santos, João Matias, and Antonio Abreu propose using multi-objective evolutionary algorithms to help consumers select sustainable household appliances. Their model maximizes economic well-being and environmental well-being by evaluating appliances based on attributes like cost, energy usage, and noise. A case study applies the model to select appliances for a 4-person household within a €2,700 budget. The results provide a Pareto frontier of efficient solutions and show potential savings of €2,112 per year in costs and 1,458 kg of CO2 emissions by adopting the model's recommendations.
Calculation Tools & ICT Insights on energy saving: SAT-S, Save@Work, GreenSpe...ICT FOOTPRINT .eu
The 4th ICTFOOTPRINT free webinar has crucial information on ICT Calculation tools and Sustainable ICT insights on energy savings, on 23rd February 2017, 15:00 CET. All those who want to improve ICT energy efficiency in their business are welcome to join us in this exciting webinar.
After years of seemingly infinite IT resources, software developers are facing new efficiency challenges on smartphones and IoT devices. Mobile users want more features, but not less battery life. Thomas Corvaisier (CEO of GREENSPECTOR) introduced the concept of software eco-design, and tell us how it may help lowering the consumption of IT resources while preserving performance and user experience.
Frédéric Croisson, from Deloitte Sustainability, showcased the ICTFOOTPRINT.eu Self-Assessment Tool for Services (SAT-S), a useful, quick and easy-to-use tool that calculates the carbon footprint of your ICT services. The tool helps users not only to make informed decisions about how to make an ICT service sustainable, but also discover the impact of ICT devices & activities in terms of Green House Gas emissions and primary energy consumption.
Energy savings can be achieved thanks to simple sustainable daily practices, which can be implemented by organisations employees. Karen Robinson shared some sustainable ICT practices and introduce the save@work initiative, which encourages public sector employee’s to come together in teams to reduce the energy consumption of their building by making small changes to their everyday energy consuming behaviours. Adding an element of competition to the project has been a significant driver in encouraging teams to really examine and challenge those unconscious energy consuming behaviours. The scale of working in a large office has also highlighted those practices that on their own seem to make almost insignificant savings but when applied across an office of over 300 people, have a very different impact.

Module 10 - Section 7,8 & 9: Enabling effects of ICTs for climate action 2011...Richard Labelle
This presentation focuses on the role of ICTs in enabling the reduction of greenhouse gas (GHG) emissions, in facilitating greater energy efficiency and overall in contributing to the promotion of sustainability and LED (low emission development).
Slide presentations developed to demonstrate how Information and Communication Technologies (ICTs) be used to address climate change, and why ICTs are a crucial part of the solution – i.e. in promoting efficiency, Green Growth & sustainable development, in dealing with climate change and for climate and environmental action. These slide presentations were delivered in February 2011 in Seongnam, near Seoul in Korea.
These presentations were developed and delivered over 2.5 days on the occasion of a Regional Training of Trainers Workshop for upcoming Academy modules on ICT for Disaster Risk Management and Climate Change Abatement. These modules were developed as part of the Academy of ICT Essentials for Government leaders developed by the United Nations (UN) Asia Pacific Centre for ICT Training (APCICT), based in Songdo City, in the Republic of South Korea.
These presentations were developed in 2011, and are somewhat out of date, but most of the principles still apply. Module 10, which has been published, does not include much of the information outlined in these presentations, which are fairly technical. They were developed to address a significant gap in understanding of the technical basis of using ICTs for climate action and because there is a clear bias in development circles against the importance of dealing with climate change mitigation in developing countries. These presentations are an attempt to redress this lack and are published here with this purpose in mind.
The author, Richard Labelle, is presently working on updating these presentations to further highlight the importance of addressing climate change and the important role that technology including ICTs, play in this effort.

Automobile Management System Project Report.pdfKamal Acharya
The proposed project is developed to manage the automobile in the automobile dealer company. The main module in this project is login, automobile management, customer management, sales, complaints and reports. The first module is the login. The automobile showroom owner should login to the project for usage. The username and password are verified and if it is correct, next form opens. If the username and password are not correct, it shows the error message.
When a customer search for a automobile, if the automobile is available, they will be taken to a page that shows the details of the automobile including automobile name, automobile ID, quantity, price etc. “Automobile Management System” is useful for maintaining automobiles, customers effectively and hence helps for establishing good relation between customer and automobile organization. It contains various customized modules for effectively maintaining automobiles and stock information accurately and safely.
When the automobile is sold to the customer, stock will be reduced automatically. When a new purchase is made, stock will be increased automatically. While selecting automobiles for sale, the proposed software will automatically check for total number of available stock of that particular item, if the total stock of that particular item is less than 5, software will notify the user to purchase the particular item.
Also when the user tries to sale items which are not in stock, the system will prompt the user that the stock is not enough. Customers of this system can search for a automobile; can purchase a automobile easily by selecting fast. On the other hand the stock of automobiles can be maintained perfectly by the automobile shop manager overcoming the drawbacks of existing system.
Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

Some reasons to integrate resilience…
To be resilient to that changes, the system should include the
capability to adapt and preserve at the same time its original
functions.
• due to the technology innovation, economic crisis (consumer
surplus), and climate change.
This occurs particularly with energy services….
• increased rate of disruptive events regarding energy area (e.g.
climate change, economic crisis, technological evolution, etc.)
challenging the way that systems are designed.

• An approach was presented to provide sustainable household appliances from the
market, to the decision-agent (consumer), by considering two objectives,
regarding sustainability; environment and economic well-being.
• The main objective, was to maximize the consumer well-being (environment and
economics) regarding the lifecycle of each appliance, during its usage phase.
• The social wellbeing was also promoted, by suit the obtained solutions to the
consumer needs.
• The relative importance, given by the DA (consumer), was also considered, in
order to weight the DA decision through both dimensions to be maximized;
• NSGA-II can also find the Pareto frontier of the solutions, providing therefore
several alternative solutions to the consumer.
• The achievements presented on this work, allows to proceed in a way of getting
a more completed approach that maximizes both dimensions of sustainability
(Economical, Environmental and Social) with the social dimension, being
therefore integrated into the model developed here, in order to better express
the consumer preferences

A New Approach to Provide Sustainable Solutions for Residential
Sector
Editor's Notes
As it mentioned before, the industry and service sectors are going through profound transformation towards digitalization and integration of new levels of “smartness”, originating therefore the 4th industrial revolution.
This transformation, is led by terms such as Industry 4.0, Smart Manufacturing and Economy 4.0, giving therefore an interdisciplinary character, expressed by an increasing digitalization and interconnection of systems, products, services and business models. The link between the physical and the cyber worlds, as well as the integration of the “exponential technologies”, are key features of this innovation trend.
The approach presented here, was developed to support a Decision-Agent (DA), who wants to acquire a set of electrical appliances (energy services) from the market.
On Fig.1, it is presented an approach to provide an optimal set of appliances, regarding each energy service, needed by the DA (e.g. Consumer
The available solutions were pre-selected, according to a set of criteria (Table 1), and based on number of occupants /consumers, to improve the use of the efficient appliances. In this work, it was considered four (e.g. family) occupants.
Additionally, the consumer wants to explore the consequences of his choices in future, regarding those made on present, and by predicting an eventual situation of indirect rebound effect, between light and air conditioner appliances.
This can be estimated by using scenario simulations during the air conditioner life cycle (previously selected), and by making changes around different light appliances (Table 2) according to a set of scenarios (Table 3).
The consumption profile was performed, by making a set of assumptions based on the hours, which was then extrapolated to a weekly and year base. However, the decision-agent (consumer) can also define its usage profile according to its needs, or by using the profile, considered in the case study presented here, as a default.
This attributes, are usually measured on different measurement scales. Therefore, in order to transform the criteria to follow the same scale and units, it was used an expression to stablish the relationship between the new and the previous value of 𝑥 𝑖𝑗 ( 𝑔 𝑗𝑡 ) , respective
Based on the value attributes previously achieved, it was used the additive model to aggregate them, referred to each option i, regarding energy service j, which was further improved, by applying optimization techniques, by using NSGAII algorithm.
The approach presented here, was developed to support a Decision-Agent (DA), who wants to acquire a set of electrical appliances (energy services) from the market.
On Fig.1, it is presented an approach to provide an optimal set of appliances, regarding each energy service, needed by the DA (e.g. Consumer
Based on the diagram of Fig.1, the decision variables can be defined as:
Where the objective is to maximize the savings for the consumer:
According to [6], it was considered the following objective function ( 𝑉 𝑅 ):
The codification used, was binary, given the complexity with the use of real formulation to tackle this problem, mainly in terms of the additional number of constraints.
The initial population was 100 individuals, and the parents were selected by using Roulette method, with a single crossover point method and crossover rate of 0,45.
The selected mutation operator, was Normal Random with a mutation rate of 0,01.
The model will be applied by using a case study, and considering a consumer (DA), who wishes to acquire 7 types of appliances. His building has four occupants (him included) and the relative importance’s ( 𝜔 𝐴 and 𝜔 𝐵 ) are respectively 0,7 and 0,3. All the remaining assumptions
The remained NSGA-II parameters (initial population, crossover and mutation rate) were defined after several computational experiments.
The parameter of max generations, was tested at first, where it was selected a maximum generation number of 90 to show that if 90 iterations were enough to find the Pareto frontier. Other parameters were also tested, such as the population size (100 individuals),the tournament size (10), the crossover rate (0.9), and the mutation rate (0.3). The obtained results, regarding 90th and 100th generations, are presented on Fig. 6 a), where it can be seen that both cases, have similar Pareto frontier. In this sense it was selected the max number iterations/generations of 90. Then, it was preformed several combinations of crossover and mutation rates of NSGA-II
On Table 4, it is presented an example of a feasible solution obtained from GAs, as well as its savings in terms of CO2 emissions, for a budget of 2600 Euros.
CO2 savings were calculated by using a carbon footprint indicator (emission factor), obtained from [20].
According to Table 4, the consumer can save up to € 215.6 (€ 1,447.1 € - 1231.5), corresponding to a reduction of 1452,9 kg of CO2 and during a period of 10 years.
In this work, it was presented an approach to provide sustainable household appliances from the market, to the decision-agent (consumer), by considering two objectives,
