Data Formats and Visual Tools for Forecast Evaluation

Authors: Andrey Davydenko, Cuong Sai, Maxim Shcherbakov
Comments: 16 Pages.

Forecast evaluation is inevitably connected with the need to store actuals and forecasts for further analysis. The issue gets complicated when it comes to handling rolling-origin forecasts calculated for many series over multiple horizons. In designing forecast data formats it is important to provide access to all the variables required for exploratory analysis and performance measurement. We show that existing approaches used to store forecast data are not always applicable for implementing reliable cross validation techniques. Here we propose flexible yet simple data schemas allowing the storage and exchange of actuals, forecasts, and additional variables of interest. We also demonstrate how various forecast evaluation tools can be implemented based on the schemas proposed.

Cryptographic Key Generation

Authors: George Rajna
Comments: 71 Pages.

Cryptography is often used in information technology security environments to protect sensitive, high-value data that might be compromised during transmission or while in storage. [41] In a step forward for information security for the Internet of Things, a team of researchers has published a new paper in the online edition of Nano Letters in which they have engineered a new type of physically unclonable function (PUF) based on interfacial magnetic anisotropy energy (IAE). [40] Researchers from Linköping University and the Royal Institute of Technology in Sweden have proposed a new device concept that can efficiently transfer the information carried by electron spin to light at room temperature-a stepping stone toward future information technology. [39] Now writing in Light Science & Applications, Hamidreza Siampour and co-workers have taken a step forward in the field of integrated quantum plasmonics by demonstrating on-chip coupling between a single photon source and plasmonic waveguide. [38] Researchers at University of Utah Health developed a proof-of-concept technology using nanoparticles that could offer a new approach for oral medications. [37] Using scanning tunneling microscopy (STM), extremely high resolution imaging of the molecule-covered surface structures of silver nanoparticles is possible, even down to the recognition of individual parts of the molecules protecting the surface. [36] A fiber optic sensing system developed by researchers in China and Canada can peer inside supercapacitors and batteries to observe their state of charge. [35] The idea of using a sound wave in optical fibers initially came from the team's partner researchers at Bar-Ilan University in Israel. Joint research projects should follow. [34] Researchers at the Technion-Israel Institute of Technology have constructed a first-of-its-kind optic isolator based on resonance of light waves on a rapidly rotating glass sphere. [33]

Wormhole Attacks as Security Risk in Wireless Sensor Networks and Countermeasures of RPL

Authors: Marco Mühl
Comments: 5 Pages. In German

Security is a big topic for basically every network. Attackers are consistently improving their methods and should always be considered a big threat. Especially in Wireless Sensor Networks (WSN) it is important to find countermeasures. But often this is a big challenge: Finding the right balance between security, effort, performance and cost is not easy. In this paper it is shown, how the Routing Protocol for Low Power and Lossy Networks (RPL) can handle an often used attack on networks: the wormhole attack.

It is Easier to Verify the Solution Than to Find it - II

Authors: Valdir Monteiro dos Santos Godoi
Comments: 14 Pages. In portuguese.

Introducing the concepts of variable languages and languages with semantic we presented an original proof of the famous P versus NP problem of Computer Science. This proof don't implies that the NP-complete problems not belongs to P, so the P versus NP-complete problem remains open, as well as it is possible (perhaps) to solve the SAT problem in polynomial time.
