"Several interdisciplinary studies highlight imperfect information as a possible explanation of skill mismatches, which in turn has implications for unemployment and informality rates. Despite information failures and their consequences, countries like Colombia (where informality and unemployment rates are high) lack a proper labour market information system to identify skill mismatches and emp…
This book is a collection of the accepted papers presented at the Workshop on Artificial Intelligence with Biased or Scarce Data (AIBSD) in conjunction with the 36th AAAI Conference on Artificial Intelligence 2022. During AIBSD 2022, the attendees addressed the existing issues of data bias and scarcity in Artificial Intelligence and discussed potential solutions in real-world scenarios. A set o…
The ongoing deployment of 5G networks is a key enabler for realizing upcoming services at scale, including the massive deployment of the Internet of Things, providing communications to support autonomous vehicles, and supporting the realization of smart cities. However, as the limitations of existing approaches become apparent, the need for next-generation technologies is growing, in terms of i…
Metal 3D printing, as an advanced forming, can manufacture parts directly from digital model by using layer by layer material build-up approach. This manufacturing method can prepare complex shape metal parts in short time, with and high precision. Three-dimensional printing processes can be classified into two major groups: Powder Bed Fusion-based technologies and Directed Energy Deposition. T…
The family of technologies collectively known as additive manufacturing (AM) technologies, and often called 3D-printing technologies, is rapidly revolutionizing industrial production. AM’s potential to produce intricate and customized parts starting from a digital 3D model makes it one of the main pillars for the forthcoming Industry 4.0. AM also offers the opportunity to preci…
Non-Abelian gauge theories, such as quantum chromodynamics (QCD) or electroweak theory, are best studied with the aid of Green’s functions that are gauge invariant off-shell, but unlike for the photon in quantum electrodynamics, conventional graphical constructions fail. The pinch technique provides a systematic framework for constructing such Green’s functions…
The purpose of this manual is to provide guidance to States in establishing their regulatory system for the certification of land aerodromes. The establishment of such a regulatory system is intended to ensure that the facilities, equipment and operational procedures at certified aero-dromes are in compliance with the Standards and Recommended Practices specified in Volume I of Annex 14 to the …
Safe aeroplane operations during all types of weather conditions are of the utmost concern to all air carers, alrport authortles, alr traffic control and users of air transport services. A revlew of the history of aeroplane accidents In the alr transportation Industry revealed that a substantial number are related to winter operations. An examination of these accidents showed a need for formall…
The differences between “international health†and “global health†are not well defined; many use the terms interchangeably. Both fields seek to address health issues that cross borâ€Âders and present hazards to diverse populations across the continents and the world. For some public health workers, international health addre…
