In this paper LQG control over unreliable communication links is derived. That to say, the channels between controller and actuators sensors are unreliable. This of growing importance as networked systems use wireless in becoming increasingly common. The problem how optimize case examined situation where components done with acknowledgments. Previous solutions finite horizon discrete time hold-...

This past October, I published an editorial (Blatt, 2015) appraising the social media phenomenon of PubPeer. I raised several issues with the Web site that I maintain do not serve the scientific community and will only entrench many of the underlying attitudes and behaviors that PubPeer claims it seeks to counter. The response tomyeditorial exceededall expectations— in 18 days it garnered 348 c...

It is well-known that several fundamental problems of fault-tolerant distributed computing, such as Consensus and Atomic Broadcast, cannot be solved in asyn-chronous systems with crash failures. These impossibility results stem from the lack of reliable failure detection in such systems. To circumvent such impossibility results, we introduce the concept of unreliable failure detectors that can ...

We describe how virtualization techniques can be used to address the problems of reliability, security, and backward compatibility in extensible systems. We specify the conditions under which this approach can be applied and present an architecture for its implementation: VEXE, or Virtual EXtension Environments. Further, we detail our experience with implementing VEXE’DD, a system for increasin...

The need for a neuronal coding scheme that is robust against the corruption of action potentials seems to support the idea of population rate coding, where the relevance of a single spike decreases proportional to the increase of population size. In order to test this intuition, we here investigate the e*ciency and robustness of a population rate coding scheme in comparison to a place coding sc...

To empirically factor out the perceived constraints affecting rice production in Kano River Irrigation Project State, Nigeria, current study used cross-sectional data collected through a semi-structured questionnaire complemented by an interview schedule from 217 farmers selected via multi-stage sampling technique 2020. High input cost, inadequate training, unreliable water supply, waterlogging...
