Delay-Based Digital Audio Effects Module for DJs and Musicians
Indiana University Purdue University IndianapolisThis module can manipulate audio signals, in real time, by modulating them in the time domain. This device is nicknamed “The Time Machine”. This device is meant for DJs and musicians who wish to be able to change characteristics about the music that they are playing during a live performance. This device allows the user to be able to change the playback speed of a song, such as slowing the song down and speeding it up. It allows the user to reverse the song. This device allows the user to perform momentary loops at various lengths for a stutter effect. This device can even change up the rhythm of a song by rearranging parts within a sequence. This device also lets the user perform vinyl effects, like what DJ’s do. This device lets the user be able to remix music on the fly and in real time.
The device has a touch screen user interface and a set of 12 hardware push buttons. The user is able program each of the buttons using a touch screen interface. The user selects which button they want to program with the touch screen interface. They can then select from a list of 25 different delay-based audio effects to program to the button. This gives the user full customizability of the layout on the control board. The user can load all 12 buttons with different effects in any arrangement they choose. The user plugs their audio device into the input of the module with a 3.5 mm jack. They then plug in a speaker or headphones. There is a Tap Tempo on the GUI used to synchronize the effects to the tempo of any song. After the song is synchronized, the user can then perform combinations of delay-based audio effects to remix any song.
The origins of this device came from a project for the Multi-Disciplinary Undergraduate Research Institution at IUPUI. I led a team of 3 other researchers where we were tasked with developing a digital audio effects module. During the research, we evaluated several different types of digital signal processors and devices to house our touch screen graphical user interface which was used in this project. I expanded on this project to add more functionality and customizability to the device.
The inspiration for this project came from a VST (Virtual Studio Technology) plugin called Gross Beat, from Image Line.Electrical Engineering Technolog

Epilepsy - Post-Traumatic or Not
This article discusses the legal issues presented in Muscarello v. Peterson. The case presents clearly the medical aspects in ascertaining whether epilepsy is a result of injury or is a result of independent factors. As the court stated, the decision rests basically on medical evidence and its evaluation by the jury

Hospital Privileges Revisited
It is the opinion of this writer that the laws relating to hospital privileges basically are sound and in the public interest.There is no clear reason to overthrow the accumulated wisdom of the last hundred years. American hospitals have become the best in the world because of the freedom with which they have been allowed to function. This does not militate against the constant march for improvement. As can be seen, there are cases where individuals are handicapped in their use of hospitals.These situations reflect social problems, not defects in existing laws which, like our Constitutional rights, sometimes are somewhat unsatisfactory in their application. Basically then, no physician has an absolute right to practice in a hospital. It would be a sad day if such a right were ever to exist. For it is the qualifications and restrictions on the privilege to practice in a hospital that have helped to eliminate , the poorly trained, the maladjusted, and the who have plagued the American medical profession and the public
Post-Traumatic Epilepsy and the Law
Post-traumatic epilepsy is a condition of great importance to the lawyer in personal injury work in that it can result from injury. In any specific case, it must be differentiated from epilepsy resulting from other causes. In addition, it is an unusual entity in that it may develop long after the injury. Therefore the probability or improbability of such a complication may be an important medicolegal consideration. This paper analyzes many of these factors and illustrates how present knowledge can be better used in the legal handling of such problems
