Levodopa is the gold standard therapy for Parkinson's disease (PD), but its prolonged usage leads to additional motor complications, namely levodopa-induced dyskinesia (LID). To assess LID and adjust drug regimens for optimal relief, patients attend regular clinic visits. However, the intermittent nature of these visits can fail to capture important changes in a person's condition. With the recent...
IEEE Standard 3004.5 provides information to help engineers select the proper low voltage circuit breaker for a particular industrial or commercial power system application. This paper is an overview of what is in this new standard and highlights the new or revised content from that contained in IEEE Standard 1015–2006 Applying Low Voltage Circuit Breakers Used in Industrial and Commercial Power Systems,...
Long-term treatment of Parkinson's disease with the dopamine precursor 3,4-dihydroxyphenylalanine (l-DOPA) is compromised by the development of motor complications, including involuntary movements termed dyskinesia. The neural mechanisms underlying l-DOPA-induced dyskinesia (LID) involve altered activity of GABAergic striatal output pathways resulting, directly and indirectly, in underactivity of...
This paper continues investigations of the concept of maximum low voltage circuit breaker ratings that facilitate fast tripping for arcing faults with a selectively coordinated system. Motor loads are the focal point of the report. Guidelines are provided for maximum motor horsepower ratings that should be used depending on the kVA rating of the suppy-side transformer. Using the guidelines should...
Guidance is provided to designers of low voltage distribution systems on the maximum low voltage feeder rating of a unit substation that will allow the secondary main circuit breaker short time or instantaneous function to be sensitive enough to detect and trip on arcing currents and still coordinate with the feeder breaker settings. Recommendations are presented based on the transformer kVA rating,...
Proposed IEEE Standard 3001-5-D1 is a preferred practice for the application of electrical apparatus in industrial and commercial facilities and includes references to ANSI/IEEE practices. This paper will focus on the information contained in this new recommended practice, identifying the rating information and other practical information that the reader may find useful.
Plug-in electric vehicles, i.e. vehicles that use electric motors as the prime means of power will begin to be mass-produced in 2011. The need for electric vehicle charging stations in industrial and commercial facilities is beginning and will grow as the number of plug-in electric vehicles, or PEVs grows. Power system engineers will face challenges when applying the electric vehicle charging stations...
Coordination studies utilize time current curves to determine the extent to which upstream overcurrent protective device pick-up and time delays must be increased to provide selectivity with downstream devices. These increases in device time delays result in increased let through energy and greater arc flash hazards. Advanced breaker trip unit technologies, including zone selective interlock, maintenance...

We report on the measurement of interstrip parameters of p-type silicon strip sensors which we are developing in a large collaboration to be used in a future tracker for the LHC upgrade. We measure on test structures with about 1 cm long strips the interstrip resistance, interstrip capacitance (at 1 MHz) and punch-through protection both pre-rad and after irradiation with 70 MeV protons to a fluence...
