Abstract: Techniques for visualizing dependent relationships in computer program analysis trace elements are described. A code analysis service analyzes computer code associated with a software application for at least one of errors or policy violations. The service outputs a trace log identifying a path within the computer code that results in an error or policy violation. The trace log includes a set of trace elements each corresponding to a line of the computer code. The output is displayed as a tree data structure including nodes. The nodes may include indentations indicating dependent relationships between and among variables initialized at lines in the computer code corresponding to the nodes. Alternatively, the nodes may be arranged as a hierarchy with edges connecting adjacent nodes, and nodes at different levels indicating dependent relationships. The tree data structure may include annotations providing additional contextual information about the actions performed at each node.

Abstract: In a method for heat treating alloy compositions within UNS N07028 the alloy composition is heated at a temperature between 1550° F. and 1750° F. for at least two hours, and then heated at a lower temperature between 1300° F. and 1550° F. for at least two hours. The alloy composition may be heated at a temperature between 1850° F. and 1950° F. for at least one hour before heating the alloy composition at a temperature between 1550° F. and 1750° F.

Abstract: Techniques for performing compile-time checks of source code using static analysis are described herein. One or more application programming interface calls to a remote computing service provider are detected in a set of source code listings using static analysis, and properties of each call are checked against a user-defined model containing rules defining incorrect behavior. If incorrect behavior is detected, a visualization is presented containing information about the incorrect behavior.

Abstract: Various technologies related to control flow integrity checking are described herein and can be used to greatly improve software security. During static analysis, a canonical control flow graph can be built. Execution of a program can be interrupted at runtime, and the call stack can be observed to verify control flow integrity of the program using the canonical control flow graph. Attacks using stack tampering can be avoided, regardless of how the stack tampering is achieved. Non-invasive techniques can be used, making the technologies applicable in situations where source code is not available. Real-time operating system protection can be supported.

Abstract: A wedge-shaped nozzle for dispensing fluids onto a round surface is disclosed. The nozzle dispenses the fluid with a generally uniform volume of fluid per unit area of the round surface to achieve rapidly a uniform thickness of applied fluid on the round surface. The wedge-shaped nozzle has orifices of equal size disposed on its bottom through which the fluid is dispensed. The orifices are disposed along arcs, with increasing numbers of orifices on the arcs at greater and greater distances of the arcs from the apex of the wedge-shaped nozzle. The numbers of the orifices on each arc are proportional to the area of an annular region determined by the arcs.

Abstract: The present invention relates to a system and a method for reducing the linewidth of ultra thin resist features. The present invention accomplishes this end by applying a densification process to an ultra thin resist having a thickness of less than about 2500 Å formed over a semiconductor structure. In one aspect of the present invention, the method includes providing a semiconductor substrate having a device film layer formed thereon. An ultra thin resist is then deposited over the device film layer. The ultra thin resist is patterned according to a desired structure or feature using conventional photolithography techniques. Following development, the ultra thin resist is implanted with a dopant. After the implantation is substantially completed, the device film layer is anisotropically etched.
