Alternatives for Navigating Small Unmanned Air Vehicles without GPS

Considering the increased reliance on GPS navigation for the Army’s Unmanned Aircraft Systems, adversaries have invested in capabilities to deny our systems access to genuine GPS signals. Although significant effort has been put forth in the areas of anti-jamming and anti-spoofing in GPS receivers, a need for alternative navigation methods in a GPS denied environment has grown in importance. This report outlines the recommendation and analysis completed for Mr. Lars Ericsson of the Army Project Manager Unmanned Aircraft Systems (PM-UAS).  The report includes background research in the domain space, comprehensive stakeholder analysis, derived system requirements and functional requirements, ending with alternative generation, value scoring, costing, and provided findings for a recommended alternative for future consideration. 

Understanding Brexit: impacts at local level: Ceredigion case study

The UK is in a critical juncture with regard to the process of negotiations to leave the European Union. Important discussions are taking place which will shape the future relation between Britain and the EU. The economic analyses published on the issue have, so far, largely failed to grasp the attention of the general public. Most of the discussions about Brexit have focused at a national level and there has been very little evidence-based discussion at a local level. This project aims at stimulating a reflexive participatory research process involving citizens, policy-makers, business people and civil-society representatives. It introduces an innovative methodology that contextualises quantitative data through expert interviews and the analysis of local sources. The reports and discussion panels organised within the framework of the project seek to increase our understanding about the impact of Brexit at a local level

Understanding Brexit: impacts at a local level: the London Borough of Barnet case study

The UK is in a critical juncture with regard to the process of negotiations to leave the European Union. Important discussions are taking place during 2018 which will shape the future relation between Britain and the EU. The economic analyses published on the issue have, so far, largely failed to grasp the attention of the general public. Most of the discussions about Brexit take place in what could be described as elite circles and tend to be London based; there has been very little evidence-based discussion at local levels. Moreover, one of the obstacles to local level evidence based discussions is a distrust of expert evidence

Understanding Brexit: impacts at a local level: Southampton case study

According to local experts and reports, only a ‘short-term slow growth’ is expected after Brexit as Southampton is not heavily dependent on EU funding or exposed to EU markets. A Brexit opportunity is to develop a skilled workforce able to compete internationally. Of the sectors identified, those that were most promising are transport and dock-related jobs. The area has individual industrial strengths that can offer opportunity under Brexit

Understanding Brexit: impacts at a local level: Mansfield case study

Mansfield was selected as a case study of a town that has undergone significant industrial restructuring during the last four decades, following the decline of traditional industries such as coal mining and textiles. Mansfield still faces acute challenges in terms of attracting high value-added businesses and increasing the skills and earnings of the local population. the remarkably high share of the Leave vote in the area cannot be understood without taking into consideration some structural characteristics of the Mansfield economy in the post-coal mining period

Non-standard neutrino interactions in IceCube

Non-standard neutrino interactions (NSI) may arise in various types of new physics. Their existence would change the potential that atmospheric neutrinos encounter when traversing Earth matter and hence alter their oscillation behavior. This imprint on coherent neutrino forward scattering can be probed using high-statistics neutrino experiments such as IceCube and its low-energy extension, DeepCore. Both provide extensive data samples that include all neutrino flavors, with oscillation baselines between tens of kilometers and the diameter of the Earth. DeepCore event energies reach from a few GeV up to the order of 100 GeV - which marks the lower threshold for higher energy IceCube atmospheric samples, ranging up to 10 TeV. In DeepCore data, the large sample size and energy range allow us to consider not only flavor-violating and flavor-nonuniversal NSI in the μ−τ sector, but also those involving electron flavor. The effective parameterization used in our analyses is independent of the underlying model and the new physics mass scale. In this way, competitive limits on several NSI parameters have been set in the past. The 8 years of data available now result in significantly improved sensitivities. This improvement stems not only from the increase in statistics but also from substantial improvement in the treatment of systematic uncertainties, background rejection and event reconstruction
