The New Hampshire Greenhouse Gas Emissions Reduction Fund: Year 3 (July 2011-June 2012) Evaluation

The Greenhouse Gas Emissions Reduction Fund (GHGERF) was created by the New Hampshire legislature in 2008 and has been administered by the New Hampshire Public Utilities Commission (PUC). The purpose of the Fund was to support energy efficiency, energy conservation, and demand response programs to reduce New Hampshire’s greenhouse gas emissions. Funding was derived from the State’s participation in the Regional Greenhouse Gas Initiative (RGGI), a cooperative effort by nine northeastern states to reduce carbon dioxide emissions in the electric power sector via a cap and trade program. As of June 2012, RGGI auctions have resulted in revenues to New Hampshire of $38.7 million, of which$21.8 million had been paid out to grants through June 2012. These funds have been distributed primarily through a competitive grant process administered by the PUC. The total amount of GHGERF grant awards is equal to 0.5% of the $6 billion that New Hampshire spends annually on energy across all sectors. These grants funded a wide variety of projects and programs which directly benefitted New Hampshire homes, schools, businesses, towns, and non-profit organizations. Details for each grant award are available at the PUC’s website. Completed projects supported by GHGERF funds (as of June 2012) have resulted in annual reductions of fossil fuel energy use in NH by 227,400 million BTUs (MMBTUs). Additionally, the GHGERF creates annual energy savings for NH residents and businesses of over$6.7 million and reduces annual carbon dioxide emissions by 22,900 metric tons. Cumulative energy savings due to projects completed as of June 2012 are estimated to be 4.0 million MMBTUs through 2030. NH residents and businesses are expected to save $107.8 million through 2030 based on current energy prices. Carbon dioxide emissions reductions are estimated to be 366,500 metric tons through 2030. In addition to energy reductions, GHGERF has supported energy efficiency workforce development for 700 workers with over 11,300 training hours (as of June 2012). GHGERF has also financially supported almost 2,300 building benchmarking and energy audit evaluations. During the past three years, GHGERF has delivered significant energy savings and served a wide-base of residential, commercial, and industrial energy customers throughout New Hampshire. The experience and capacity built during the three year period allowed GHGERF to deliver the highest amount of energy saved per dollar spent during this past reporting period. The model of having a central specialized expert organization work with multiple energy customers, as seen in all of the grants awarded in 2010, has proven to be a successful one and should be considered as NH’s RGGI program shifts to the NH electric utility energy efficiency programs

Spectroscopy of D-type asteroids

We have performed a spectroscopic survey of 19 D-type asteroids. Comparison with previous photometry shows excellent agreement. Although the majority have similar colors to cometary nuclei, no cometary emission bands were present in any of the spectra. Absorption bands sporadically appearing were apparently due to stellar objects, and no features inherent to the asteroids were observed

New rr-Matrices for Lie Bialgebra Structures over Polynomials

For a finite dimensional simple complex Lie algebra $\mathfrak{g}$, Lie bialgebra structures on $\mathfrak{g}[[u]]$ and $\mathfrak{g}[u]$ were classified by Montaner, Stolin and Zelmanov. In our paper, we provide an explicit algorithm to produce $r$-matrices which correspond to Lie bialgebra structures over polynomials

Insights into the Fallback Path of Best-Effort Hardware Transactional Memory Systems

DOI 10.1007/978-3-319-43659-3Current industry proposals for Hardware Transactional Memory (HTM) focus on best-effort solutions (BE-HTM) where hardware limits are imposed on transactions. These designs may show a significant performance degradation due to high contention scenarios and different hardware and operating system limitations that abort transactions, e.g. cache overflows, hardware and software exceptions, etc. To deal with these events and to ensure forward progress, BE-HTM systems usually provide a software fallback path to execute a lock-based version of the code. In this paper, we propose a hardware implementation of an irrevocability mechanism as an alternative to the software fallback path to gain insight into the hardware improvements that could enhance the execution of such a fallback. Our mechanism anticipates the abort that causes the transaction serialization, and stalls other transactions in the system so that transactional work loss is mini- mized. In addition, we evaluate the main software fallback path approaches and propose the use of ticket locks that hold precise information of the number of transactions waiting to enter the fallback. Thus, the separation of transactional and fallback execution can be achieved in a precise manner. The evaluation is carried out using the Simics/GEMS simulator and the complete range of STAMP transactional suite benchmarks. We obtain significant performance benefits of around twice the speedup and an abort reduction of 50% over the software fallback path for a number of benchmarks.Universidad de Málaga.

Evaluation of laser range-finder mapping for agricultural spraying vehicles

In this paper, we present a new application of laser range-finder sensing to agricultural spraying vehicles. The current generation of spraying vehicles use automatic controllers to maintain the height of the sprayer booms above the crop. However, these control systems are typically based on ultrasonic sensors mounted on the booms, which limits the accuracy of the measurements and the response of the controller to changes in the terrain, resulting in a sub-optimal spraying process. To overcome these limitations, we propose to use a laser scanner, attached to the front of the sprayer's cabin, to scan the ground surface in front of the vehicle and to build a scrolling 3d map of the terrain. We evaluate the proposed solution in a series of field tests, demonstrating that the approach provides a more detailed and accurate representation of the environment than the current sonar-based solution, and which can lead to the development of more efficient boom control systems

Relaxation of the field-cooled magnetization of an Ising spin glass

The time and temperature dependence of the field-cooled magnetization of a three dimensional Ising spin glass, Fe_{0.5}Mn_{0.5}TiO_{3}, has been investigated. The temperature and cooling rate dependence is found to exhibit memory phenomena that can be related to the memory behavior of the low frequency ac-susceptibility. The results add some further understanding on how to model the three dimensional Ising spin glass in real space.Comment: 8 pages RevTEX, 5 figure
