How Singapore is Paving the Way for Global Smart CitiesSolace
Singapore is at the leading edge of global smart city initiatives and is a good deal of the way along the path to truly transforming the “city nation” for the benefit of its citizens and the redefinition of its government. Everything is on the table for reinvention in Singapore from smart transportation to smart energy to smart buildings to how its citizens receive smarter healthcare.
But what is a “smart city”? A smart city uses technology to deliver services, uses technology to reduce costs for service providers and uses technology to allow citizens to improve the running of the city. With sensors planted measuring everything from traffic to street lights, Singapore has deep insights into the lessons in IoT deployment and delivery on a truly large scale.
On October 13th, 2016 at the Internet of Things Developer meetup, Sumeet Puri presented a social and technical perspective on the Singapore smart cities initiative from two viewpoints: his role as an architect of several Singapore Smart City projects and as a resident of Singapore living through the transformation of his surroundings. Sumeet will share stories about Singapore’s efforts, and give us insights into the technical decisions needed to make this a reality. Sumeet will talk about architecting for IoT at scale, lessons learned from the Singapore Smart City Initiatives and the response of the public to these changes.
This is a presentation that focuses on autonomous vehicles technology. The presentation describes key sensor technologies integrated under the bonnet of a driverless car. After a brief introduction, the presentation dwells deeper into each sensor technology demonstrating examples of self driving cars such as Google's self driving car, DARPA URBAN challenge etc., along the way. It also introduces the concept of electronic control units which is responsible for collecting data from different sensors and respond to other units accordingly. The slides also build a platform for vehicle to vehicle communication technology, types and its application areas.
Bringing the Internet of Things “IoT” to Government: Enabling Smart NationsAmazon Web Services
Local and regional governments around the world are using the cloud to transform services, improve their operations, and reach new horizons for citizen services. People are more connected to each other than ever before, and the increased connectivity of devices creates new opportunities for the public sector to truly become hubs of innovation, driving technology solutions to help improve citizens' lives. This session highlights how AWS IoT enables applications to communicate with all of your devices, all the time, even when they aren’t connected, with the goal of driving cost savings, innovation, and enhanced decision making for smarter cities.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

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.
