An assumption-based truth-maintenance system
- Artificial Intelligence
, 1986
"... In this paper we (1) define the concept of a Clause Man-agetnent System (CMS) — a generaizatiou of de Kleer’s ATMS, (2) motivate such systems in terms of efficiency of search and abductive reasoning, and (3) characterize the computation affected by a CMS in terms of the concept of prime implicants. ..."

it does, oc-casionally transmits a propositional clause2 to the CMS. The Reasoner is also permitted to query the CMS any time it feels so inclined. A query takes the form of a proposi-tional clause C. The CMS is expected to respond with every shortest clause S for which the clause S V C is a log
Reevaluating Amdahl’s law
- Commun. ACM
, 1988
"... At Sandia National Laboratories, we are currently en-gaged in research involving massively parallel process-ing. There is considerable skepticism regarding the via-bility of massive parallelism; the skepticism centers around Amdahl’s law, an argument put forth by Gene Amda.hl in 1967 [l] that even w ..."

Memory access buffering in multiprocessors
- In Proceedings of the 13th Annual International Symposium on Computer Architecture
, 1986
"... In highly-pipelined machines, instructions and data are prefetched and buffered in both the processor and the cache. This is done to reduce the average memory access la-tency and to take advantage of memory interleaving. Lock-up free caches are designed to avoid processor blocking on a cache miss. W ..."

The neural substrate of human empathy: effects of perspective-taking and cognitive appraisal
- J Cogn Neurosci
"... & Whether observation of distress in others leads to empathic concern and altruistic motivation, or to personal distress and egoistic motivation, seems to depend upon the capacity for self–other differentiation and cognitive appraisal. In this experi-ment, behavioral measures and event-related f ..."

Learning interface agents
- In AAAI
, 1993
"... Interface agents are computer programs that employ Artificial Intelligence techniques in order to provide assistance to a user dealing with a particular comput-er application. The paper discusses an interface agent which has been modelled closely after the metaphor of a personal assistant. The agent ..."

. The agent learns how to as-sist the user by (i) observing the user’s actions and imitating them, (ii) receiving user feedback when it takes wrong actions and (iii) being trained by the us-er on the basis of hypothetical examples. The paper discusses how this learning agent was implemented us-ing memory
Improved query performance with variant indexes
, 1997
"... Abstract: The read-mostly environment of data warehousing makes it possible to use more complex indexes to speed up queries than in situations where concurrent updates are present. The current paper presents a short review of current indexing technology, including row-set representation by Bitmaps, ..."

, and then introduces two approaches we call Bit-Sliced indexing and Projection indexing. A Projection index materializes all values of a column in RID order, and a Bit-Sliced index essentially takes an orthogonal bit-by-bit view of the same data. While some of these concepts started with the MODEL 204 product

A Locally Adaptive Data Compression Scheme
, 1986
"... A data compression scheme that exploits locality of reference, such as occurs when words are used frequently over short intervals and then fall into long periods of disuse, is described. The scheme is based on a simple heuristic for self-organizing sequential search and on variable-length encoding ..."

How long will it take to fix this bug
- In Workshop on Mining Software Repositories
, 2007
"... Predicting the time and effort for a software problem has long been a difficult task. We present an approach that au-tomatically predicts the fixing effort, i.e., the person-hours spent on fixing an issue. Our technique leverages existing issue tracking systems: given a new issue report, we use the ..."

Our approach thus allows for early effort estimation, helping in assign-ing issues and scheduling stable releases. We evaluated our approach using effort data from the JBoss project.
