This paper takes as its point of departure advocacy planning approaches’ consideration that urban renewal is incompatible with any kind of socially effective urban planning. It focuses on analysing the Architects’ Renewal Committee in Harlem (ARCH), the first organisation solely devoted to advocacy planning in the United States, and places particular emphasis on the critiques of urban renewal strategies in the late 1960s in the North-Eastern ...

Modern messaging applications often rely on out-of-band communication to achieve entity authentication, with human users verifying and attesting to long-term public keys. This is done primarily to reduce reliance on trusted third parties by replacing that role with the user. Despite a great deal of research focusing on analyzing the confidentiality aspect of secure messaging, the entity authenticity aspect of it, which relies on the user ...

All-digital basestation (BS) architectures for millimeter-wave (mmWave) massive multi-user multiple-input multiple-output (MU-MIMO), which equip each radio-frequency chain with dedicated data converters, have advantages in spectral efficiency, flexibility, and baseband-processing simplicity over hybrid analog-digital solutions. For all-digital architectures to be competitive with hybrid solutions in terms of power consumption, novel ...

The need for fast and robust optimization algorithms are of critical importance in all areas of machine learning. This paper treats the task of designing optimization algorithms as an optimal control problem. Using regret as a metric for an algorithm's performance, we study the existence, uniqueness and consistency of regret-optimal algorithms. By providing first-order optimality conditions for the control problem, we show that regret-optimal ...
