A high-speed digital signal processor for atmospheric radar, part 7.3A

The Model SP-320 device is a monolithic realization of a complex general purpose signal processor, incorporating such features as a 32-bit ALU, a 16-bit x 16-bit combinatorial multiplier, and a 16-bit barrel shifter. The SP-320 is designed to operate as a slave processor to a host general purpose computer in applications such as coherent integration of a radar return signal in multiple ranges, or dedicated FFT processing. Presently available is an I/O module conforming to the Intel Multichannel interface standard; other I/O modules will be designed to meet specific user requirements. The main processor board includes input and output FIFO (First In First Out) memories, both with depths of 4096 W, to permit asynchronous operation between the source of data and the host computer. This design permits burst data rates in excess of 5 MW/s

Quality and price of fresh market strawberries in West Tennessee

Tennessee strawberry producers have received an average of about three and one-half million dollars annually from strawberry sales for the past ten years. While this amount is less than one percent of the state\u27s total crop value, strawberries rank eighth as a source of crop income. In addition to being the most widely grown truck crop, they have been in most years the most valuable crop. Unlike most other crops, the characteristics of the strawberry make the marketing process extremely difficult. The product grade or quality as established on the farm never improves during the product\u27s journey to the consumer. Deterioration sets in immediately after harvest, many times before, and continues at a rate determined by environmental conditions. The primary environmental factors of temperature and humidity are not always easily controlled in the marketing process, as evidenced by present marketing techniques. It is, therefore, very important that as strawberries start through the marketing channels that they have the proper quality characteristics if they are to make this market journey successfully. Many factors Influencing quality on the farm cannot be controlled but harvesting methods can directly influence the product grade. While quality receives much credit for the success of a marketing season, the medium of awarding such success is through price. Costa and returns are the final guage for the grower in measuring the success of a particular enterprise. The quality of a product is expected to respond to price incentive and price is expected to rise or fall with quality where quality is the main consideration in establishing price. Quality is supposed to provide a basis for establishing value at the various levels of marketing and is especially important in determining first sale price of some farm products. The grade or degree of quality is described by industry-wide standards and the respondent price is supposedly determined by product demand and supply the translation of these forces by local marketing firms. Yet, it may be that impediments arise which so reduce the level of interplay between these forces that proper responses are not seen in certain markets. The farmer and the marketing firm are both strongly concerned with price and quality factors

Synthesis and 1 H‐nmr of deuterium labeled D,L‐homoserine lactone hydrochlorides

The synthesis of six regiospecific deuterated D,L‐homoserine lactone hydrochlorides from the appropriately deuterated 2‐bromo‐1‐(tetrahydropyranyloxy) ethanes which were obtained by reduction of the corresponding ethyl bromoacetates are described. The proton nmr of each lactone is recorded and the chemical shift and coupling constants are reported.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/90051/1/2580240404_ftp.pd

Evaporite karst geohazards in the Delaware Basin, Texas: review of traditional karst studies coupled with geophysical and remote sensing characterization

Evaporite karst throughout the Gypsum Plain of west Texas is complex and extensive, including manifestations ranging from intrastratal brecciation and hypogene caves to epigene features and suffosion caves. Recent advances in hydrocarbon exploration and extraction has resulted in increased infrastructure development and utilization in the area; as a result, delineation and characterization of potential karst geohazards throughout the region have become a greater concern. While traditional karst surveys are essential for delineating the subsurface extent and morphology of individual caves for speleogenetic interpretation, these methods tend to underestimate the total extent of karst development and require surficial manifestation of karst phenomena. Therefore, this study utilizes a composite suite of remote sensing and traditional field studies for improved karst delineation and detection of potential karst geohazards within gypsum karst. Color InfraRed (CIR) imagery were utilized for delineation of lineaments associated with fractures, while Normalized Density Vegetation Index (NDVI) analyses were used to delineate regions of increased moisture flux and probable zones of shallow karst development. Digital Elevation Models (DEM) constructed from high-resolution LiDAR (Light Detection and Ranging) data were used to spatially interpret sinkholes, while analyses of LiDAR intensity data were used in a novel way to categorize local variations in surface geology. Resistivity data, including both direct current (DC) and capacitively coupled (CC) resistivity analyses, were acquired and interpreted throughout the study area to delineate potential shallow karst geohazards specifically associated with roadways of geohazard concern; however, detailed knowledge of the surrounding geology and local karst development proved essential for proper interpretation of resistivity inversions. The composite suite of traditional field investigations and remotely sensed karst delineations used in this study illustrate how complex gypsum karst terrains can be characterized with greater detail through the utilization of rapidly advancing technologies, especially in arid environments with low vegetation densities

The Conservative Tradition in America

Conservatism, once at the periphery of American politics. now occupies a central and strategic position in the seat of political power. The 1994 election confined a realignment of American politics along conservative lines In the general electorate, but in the halls of academe conservatism remains a neglected subject, on the fringes of the curriculum and outside the door of the faculty lounge Many academics are politically liberal, and few scholars in the social science disciplines take conservative intellectual positions seriouslyhttps://tigerprints.clemson.edu/faculty_monographs/1001/thumbnail.jp
