Sector-Based Detection for Hands-Free Speech Enhancement in Cars
, 2004
"... Abstract. Speech-based command interfaces are becoming more and more common in cars. Applications include automatic dialog systems for hands-free phone calls as well as more advanced features such as navigation systems. However, interferences, such as speech from the codriver, can greatly hamper the ..."

of the filtered output signal. The “explicit” method decides whether to adapt or not in a binary fashion, depending on prior estimation of target and interference energies. A major contribution of this paper is a direct, robust method for such estimation, directly derived from sector-based detection
Further Applications of Sector-Based Detection and Short-Term Clustering
, 2006
"... This paper presents an effective implementation of detection-localization of multiple speech sources with microphone arrays. In particular, the Scaled Conjugate Gradient descent is used for fast and precise localization, within a pre-detected volume of space, and a close to realtime implementation ..."

A sector-based, frequencydomain approach to detection and localization of multiple speakers
- in Proc. ICASSP
"... Detection and localization of speakers with microphone arrays is a difficult task due to the wideband nature of speech signals, the large amount of overlaps between speakers in spontaneous conversations, and the presence of noise sources. Many existing audio multi-source localization methods rely on ..."

on prior knowledge of the sectors containing active sources and/or the number of active sources. This paper proposes sector-based, frequency-domain approaches that address both detection and localization problems by measuring relative phases between microphones. The first approach is similar to delay

ENVIRONMENT AND BEHAVIOR / January 1999Bratt / CONSUMERS ’ ENVIRONMENTAL BEHAVIOR CONSUMERS’ ENVIRONMENTAL BEHAVIOR Generalized, Sector-Based, or Compensatory?
"... sarch interests focus on attitudes and behavior. ABSTRACT: The means applied to promote environmentally friendly behavior need to be evaluated. This study investigates the possibility that actions meant to improve recycling may have unintended consequences in fields other than the target behavior. T ..."

The relation between self-reported environmental behaviors in several sectors is stud-ied, with particular attention given to the question of whether increased recycling may develop into a compensatory behavior for less environmentally friendly behavior elsewhere.

Latent Sector Error Modeling and Detection for NAND Flash-based SSDs
"... Latent Sector Error (LSE) is a well-known problem in HDD-based storage systems. LSEs, which occur silently, may result in data loss during RAID recovery from disk failure. LSEs in HDDs are caused by various reasons such as write errors or media imperfections [1], which result in bit/symbol errors th ..."

HULL DETECTION BASED ON LARGEST EMPTY SECTOR ANGLE WITH APPLICATION TO ANALYSIS OF REALTIME MR IMAGES
"... We present a novel view of the hull detection problem in two dimensions. Our proposed method is based on the principle of finding Pareto optimal boundaries and extends it to the gen-eral problem of finding a hull for a given set of points. We first compute the largest empty sector angle (LESA) score ..."

Dumb money: Mutual fund flows and the cross section of stock returns,
- Journal of Financial Economics,
, 2008

ABSTRACT We use mutual fund flows as a measure for individual investor sentiment for different stocks, and find that high sentiment predicts low future returns. Fund flows are dumb ..."

sentiment affects stock prices, and specifically whether one can predict future stock returns using a flow-based measure of sentiment. If sentiment pushes stock prices above fundamental value, high sentiment stocks should have low future returns. For example, in 1999 investors sent $36 billion to Janus

PATTERN-BASED SEMI-AUTOMATIC ANALYSIS OF WEAKNESSES IN SEMANTIC BUSINESS PROCESS MODELS IN THE BANKING SECTOR

As banks have realized the need to look on their business in a process-oriented way, they have been engaged in numerous business process optimization or even reengineering (BPR) projects in the last decade to make their organizations more efficient. However, the success of BPR projects in banks vari ..."

) is yet in its infancy. Value from business process modeling can, however, only be unveiled when time-consuming, mostly manual business process analysis is performed and results in business process optimization. In this paper we develop a methodology for semi-automatic analysis and detection of weaknesses
