High-latitude ion transport and energetic explorer (HI-LITE): a mission to investigate ion outflow from the high-latitude ionosphere

The proposed HI-LITE Explorer will investigate the global ion outflow from the high-latitude ionosphere, its relationship to auroral features, and the consequences of this outflow on magnetospheric processes. The unique nature of the HI-LITE Explorer images will allow temporal and spatial features of the global ion outflow to be determined. The mission's scientific motivation comes from the fundamental role high-latitude ionospheric ions play in the dynamics of the solar wind driven magnetospheric-ionospheric system. These outflows are a major source of plasma for the magnetosphere and it is believed they play an important role in the triggering of substorms. In addition this paper describes the HI-LITE spacecraft and instruments.

Extracting planetary waves from geomagnetic time series using Empirical Mode Decomposition

Empirical Mode Decomposition is presented as an alternative to traditional analysis methods to decompose geomagnetic time series into spectral components. Important comments on the algorithm and its variations will be given. Using this technique, planetary wave modes of 5-, 10-, and 16-day mean periods can be extracted from magnetic field components of three different stations in Germany. In a second step, the amplitude modulation functions of these wave modes can be shown to contain significant contribution from solar cycle variation through correlation with smoothed sunspot numbers. Additionally, the data indicate connections with geomagnetic jerk occurrences, supported by a second set of data providing reconstructed near-Earth magnetic field for 150 years. Usually attributed to internal dynamo processes within the Earth's outer core, the question of who is impacting whom will be briefly discussed here.

Dennis Mahoney, Electrician, Consolidated Edison Company, New York

A graduate of the New York Trade School's Electrical program in 1958, Dennis Mahoney is show at work for the Consolidated Edison Company in New York. Caption written on reverse reads "Dennis J. Mahoney is shown closing the Armature Switch of a Rotary Converter in a D.C. substation. The average rotary in our stations has a capacity of 4,200 K.W. and there are 30 such stations in Manhattan with an annual output of 800,000 amperes. Although the D.C. load is gradually being reduced, it can be seen that there is still considerable demand for direct current in Manhattan." Black and white photograph.

Hydropower Energy Simulation Using Mike 11 Model; A Case Study In South Germany's Small Run-Of-River Hydropower Plants

Renewable energy production is a basic supplement to stabilize rapidly increasing global energy demand and skyrocketing energy price as well as to balance the fluctuation of supply from non-renewable energy sources at electrical grid hubs. The European energy traders, government and private company energy providers and other stakeholders have been, since recently, a major beneficiary, customer and clients of Hydropower simulation solutions. The relationship between rainfall-runoff model outputs and energy productions of hydropower plants has not been clearly studied. In this research, association of rainfall, catchment characteristics, river network and runoff with energy production of a particular hydropower station is examined. The essence of this study is to justify the correspondence between runoff extracted from calibrated catchment and energy production of hydropower plant located at a catchment outlet; to employ a unique technique to convert runoff to energy based on statistical and graphical trend analysis of the two, and to provide environment for energy forecast. For rainfall-runoff model setup and calibration, MIKE 11 NAM model is applied, meanwhile MIKE 11 SO model is used to track, adopt and set a control strategy at hydropower location for runoff-energy correlation. The model is tested at two selected micro run-of-river hydropower plants located in South Germany. Two consecutive calibration is compromised to test the model; one for rainfall-runoff model and other for energy simulation. Calibration results and supporting verification plots of two case studies indicated that simulated discharge and energy production is comparable with the measured discharge and energy production respectively.

The Apple of His Ire: For monologist Mike Daisey, the death of Steve Jobs was another defining moment in a remarkable career

Interview with Dennis Stamper

In his January 12, 2015 interview with Michelle Dubert-Bellrichard, Dennis Stamper shares his memories of being one of the first male, day students from 1969-1972. Stamper details his studies and professors from the Philosophy and Religion Department, as well as the Psychology Department. Stamper includes his perception of the atmosphere at Winthrop during a time of great change in the country, and how that experience coupled with his work in the Wesley Foundation and the influence he received from professors paved the way for he currently lives his life. Stamper concludes his interview detailing his studies and careers after Winthrop. This interview was conducted for inclusion into the Louise Pettus Archives and Special Collections Oral History Program.
