Design Patterns for Graceful Degradation ∗
"... The term graceful degradation describes the smooth change to a lower state of some system aspect as a response to the occurrence of an event that prohibits the manifestation of the fully fledged system behavior. Graceful degradation has appeared in a variety of domains, from image processing and tel ..."

Gracefully degradable pipeline networks
, 1996
"... A pipeline is a linear array of processors with an input node at one end and an output node at the other end. This paper presents k-gracefully-degradable graphs which, given any set of up to k faults, contain a pipeline that uses all the healthy processor nodes. Our constructions are designed to tol ..."

Graceful Degradation of Hand Gestures
"... Embodied Conversational Agents (ECAs) should interact with the user in a reactive way, using non-verbal modalities parallel to speech. Hand gestures, particularly, should be generated on the fly, and precisely timed to speech. However, this does not always succeed. In this short paper we discuss wha ..."

of graceful degradation of timing, in the framework of our GESTYLE gesture markup language.
Graceful Degradation in the Presence of Exceptions
"... In today’s software development processes, exception handling is mostly considered as an issue of minor impor-tance. Furthermore, explicit and systematic exception han-dling strategies and tool-support for reasoning about excep-tion flow and exception compatibility between components are very rare. ..."

Specifying graceful degradation in distributed systems
- ACM TODS
"... Distributed programs must often display graceful degradation, reacting adaptively to changes in the environment. Under ideal circumstances, the program’s behavior satisfies a set of application-dependent constraints. In the presence of failures, timing anomalies, or synchronization conflicts, howeve ..."

Graceful Degradation in Multi-Party Computation ⋆
"... Abstract. The goal of Multi-Party Computation (MPC) is to perform an arbitrary computation in a distributed, private, and fault-tolerant way. For this purpose, a fixed set of n parties runs a protocol that tolerates an adversary corrupting a subset of the participating parties, and still preserves c ..."

are only passive. In this paper, we provide the first treatment of MPC with graceful degradation of both security and corruptions. First of all, our protocols provide graceful degradation of security, i.e., different security guarantees depending on the actual number of corrupted parties: the more
A Product Family Approach To Graceful Degradation
, 2000
"... Design of gracefully degrading systems, where functionality is gradually reduced in the face of faults, has traditionally been a very difficult and error-prone task. General approaches to graceful degradation are typically limited to re-implementation of the system for a number of pre-designated fal ..."

Performance of graceful degradation for cache faults
- In IEEE Computer Society Annual Symposium on VLSI
, 2007
"... In sub-90nm technologies, more frequent hard faults pose a serious burden on processor design and yield control. In addition to manufacturing-time chip repair schemes, microarchitectural techniques to make processor components resilient to hard faults will become increasingly important. This paper c ..."

considers defects in cache memory and studies their impact on program performance using a fault degradable cache model. We first describe how defects at the circuit level in cache manifest themselves at the microarchitecture level. We then examine several strategies for masking faults, by disabling faulty
High-Level Synthesis of Gracefully Degradable ASICs
- in Proceedings of European Design and Test Conference
, 1996
"... We propose a novel graceful degradation scheme, L/U reconfiguration, which can tolerate a single permanent fault in each hardware class of ASIC datapaths. In the proposed scheme, dynamic hardware rebinding and operation rescheduling are performed by a systematic perturbation of the original configur ..."

Graceful Degradation of Speech Recognition Performance
- In: Proc. Eurospeech01
, 2001
"... This paper explores packet loss recovery in client-server Automatic Speech Recognition (ASR) systems. A forward error correction (FEC) system is designed and tested over several channel loss models, at variable amounts of data acquisition delay. In experiments with simulated packet loss, the FEC sys ..."

system provides robust ASR performance which degrades gracefully as packet loss rates increase. Comparing this scheme to several alternatives under low and medium loss channel conditions, we found one approach (multiple transmission plus interpolation) that yielded similar performance, but the FEC system
