Climate Refugees: Uncertainty and InsecurityJosh Gellers
This lecture presents the precarious state of climate refugees, whose status is not defined under current international law. It examines several case studies (Syria, Tuvalu, and Kivalina) in which populations are on the move or are under imminent danger as a result, directly or indirectly, of climate change. The presentation also evaluates several possible solutions devised by legal scholars and political scientists to address to what many regard as an impending crisis.
How Raft consensus algorithm will make replication even better in MongoDB 3.2...Ontico
MongoDB exhibits a fairly classic leader-based replication architecture, with builtin automatic provisioning and failovers. Since it was developed, an academic paper from Stanford has introduced a distributed consensus algorithm called Raft — which happens to be rather similar to the home grown algorithm of MongoDB. This talk will give a brief overview of Raft and how we are retrofitting some of it into MongoDB 3.2 to make our replication even more robust.
This talk is quick reference of all the different queerability options that MongoDB offers to developers that want to build mobile and geospatial referenced applications. We reviewed the basic functionality but also recent improvements in the query and indexation engine of MongoDB geospatial features

To meet customers' requirements for high-quality networks, LTE trial networks must be optimized during and after project implementation. Radio frequency (RF) optimization is necessary in the entire optimization process. This document provides guidelines on network optimization for network planning and optimization personnel.
LTE specifications support the use of multiple antennas at both transmitter (tx) and receiver (rx). MIMO (Multiple Input Multiple
Output) uses this antenna configuration.
LTE specifications support up to 4 antennas at the tx side and up to 4 antennas at the rx side (here referred to as 4x4 MIMO
configuration).
In the first release of LTE it is likely that the UE only has 1 tx antenna, even if it uses 2 rx antennas. This leads to that so called
Single User MIMO (SU-MIMO) will be supported only in DL (and maximum 2x2 configuration).
The Master Information Block (MIB), which includes a limited number of the most frequently transmitted parameters which are essential for a UE’s initial access to the network.
System Information Block Type 1 (SIB1), which contains parameters needed to determine if a cell is suitable for cell selection, as well as information about the time domain scheduling of the other SIBs.
System Information Block Type 2 (SIB2), which includes common and shared channel information
Main purpose of this document is to discuss LTE basic call flows.
It also introduces LTE network architecture, Nodes, their functionality as well as interfaces that
connect these network nodes.
A brief description of UE states is also given.

Handover between WCDMA and GSM allows the GSM network to be used
to give fallback coverage for WCDMA technology. This means that subscribers
can experience seamless services—even with a phased build-out
of WCDMA—which is of importance to the commercial launches in 2003.
As the leading total system provider, Ericsson has developed technologies
that overcome the challenges of interworking between WCDMA and
GSM. For example, Ericsson was first to demonstrate handover from
WCDMA to GSM in a live network.
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.
