by Alfred Aho, Sean Gallagher, Nancy Griffeth, Cynthia Schell, and Deborah Swayne Abstract We describe a language called Chisel and an editing tool for Chisel called Sculptor for defining requirements for communications services. The purpose of Sculptor and Chisel is to speed the service creation process by improving communication between organizations, by automating tedious manual work, and by...

Historical and recent challenges to the practice of comparative forensic examination have created a driving force for the formation of objective methods for toolmark identification. In this study, fifty sequentially manufactured chisels were used to create impression toolmarks in lead (500 toolmarks total). An algorithm previously used to statistically separate known matching and nonmatching st...

Motivation: Availability of large volumes of genomic and enzymatic data for taxonomically and phenotypically diverse organisms enables researchers to explore the adaptive mechanisms that led to diversification of enzymatic functions. We present Chisel, a computational framework and a pipeline for an automated, high-resolution analysis of evolutionary variations of enzymes. Chisel allows automat...

OBJECTIVE The aim of this study was to evaluate the influence of different splitting techniques, namely, "mallet and chisel" versus "spreading and prying", used during bilateral sagittal split osteotomy (BSSO) on postoperative hypoesthesia outcomes. STUDY DESIGN We systematically searched the PubMed and Cochrane databases (from January 1957 to November 2012) for studies that examined postoper...

The CHISEL notation was developed by Bellcore as an informal graphical notation for describing telecomms services and features. CRESS (CHISEL Representation Employing Systematic Specification) is an enhanced version of CHISEL with tightly defined rules for the syntax and static semantics of diagrams. More importantly, CRESS has formal denotations given by SDL (Specification and Description Lang...

We present a novel interaction device tracked in 6 degrees of freedom by two commodity cameras. The inexpensive Light Chisel is statically illuminated with two LEDs, and uses no additional sensor (e.g. inertial or magnetic) or means of communication or synchronization. Its form factor is well suited for a screwdriver or chisel grip, allowing the Light Chisel to be rolled between the fingers. Th...

Ultrasonic assisted drilling (UAD) has been reported effective for thrust force reduction during drilling of CFRP resulting in lower exit delamination. However, this process is not fully understood in relation to machining theory. This work focused on understanding the separate effects of chisel and cutting edges during UAD in comparison with conventional drilling (CD). Experiments were perform...

Excessive harvest of corn (Zea mays L.) stover for ethanol production has raised concerns regarding negative consequences on soil physical quality. Our objective was to quantify the impact of two tillage practices and three levels of corn stover harvest on near-surface soil physical quality through the Least Limiting Water Range (LLWR). We evaluated no harvest, moderate and high stover harvest ...
