Efficient Certification of Endpoint Control on Blockchain

PCP: Efficient Endpoint Congestion Control

In this paper, we present the design, implementation, and evaluation of a novel endpoint congestion control system that achieves near-optimal performance in all likely circumstances. Our approach, called the Probe Control Protocol (PCP), emulates network-based control by using explicit short probes to test and temporarily acquire available bandwidth. Like TCP, PCP requires no network support be...

Blockchain Based Access Control

Access Control systems are used in computer security to regulate the access to critical or valuable resources. The rights of subjects to access such resources are typically expressed through access control policies, which are evaluated at access request time against the current access context. This paper proposes a new approach based on blockchain technology to publish the policies expressing t...

Efficient Public Blockchain Client for Lightweight Users

Public blockchains provide a decentralized method for storing transaction data and have many applications in different sectors. In order for users to track transactions, a simple method is to let them keep a local copy of the entire public ledger. Since the size of the ledger keeps growing, this method becomes increasingly less practical, especially for lightweight users such as IoT devices and...

Biomechanical Constraints on the Control of Endpoint Stiffness

INTRODUCTION Humans regulate arm mechanics to allow for stable interactions with the environment across a broad range of tasks. Understanding how this regulation occurs is an essential problem in motor control. The steady state mechanical properties of the arm can be characterized by endpoint stiffness, the relationship between externally applied displacements of the hand and the steady state f...
