Hush kit for the Pratt and Whitney JT8D-1 through -17 engines Two JT4As installed on a KLM DC-8. A hush kit is an aerodynamic device used to help reduce the noise produced by older aircraft jet engines. These devices are typically installed on older turbojet and low-bypass turbofan engines, as they are much louder than later high-bypass ...
Hans-Joachim Haase (1915 – December 20, 2001) was a German clockmaker, optician and inventor, who became known for an apparatus for testing binocular vision and for the MKH method, an alternative method intended to improve binocular vision using corrective lenses.
The motor system acts to point both eyes at the target of interest; any offset is detected visually (and the motor system corrects it). Heterophoria occurs only during dissociation of the left eye and right eye, when fusion of the eyes is absent.
PRISM (Parallel Reduced Instruction Set Machine) [1] was a 32-bit RISC instruction set architecture (ISA) developed by Digital Equipment Corporation (DEC). It was the outcome of a number of DEC research projects from the 1982–1985 time-frame, and the project was subject to continually changing requirements and planned uses that delayed its introduction.
The lower prism uses one total internal reflection, followed by a second reflection on the bottom surface to direct the beam into the second Schmidt prism. This second reflection in the lower prism happens at less than the critical angle, therefore the Schmidt–Pechan prism requires a reflective coating for this surface to be usable in ...
The Oregon Department of Corrections is the agency of the U.S. state of Oregon charged with managing a system of 12 state prisons since its creation by the state ...
Digital room correction may involve minimum phase algorithms, to maintain wavefront coherence over the intended frequency range. The use of analog filters, such as equalizers, to normalize the frequency response of a playback system has a long history; however, analog filters are very limited in their ability to correct the distortion found in many rooms.
The victim navigates to a website infected by an exploit kit. Links to infected pages can be spread via spam, malvertising, or by compromising legitimate sites. The victim is redirected to the landing page of the exploit kit. The exploit kit determines which vulnerabilities are present, and which exploit to deploy against the target.
