Werner Enterprises Strategic Audit

Werner Enterprises is a large trucking company based in Omaha, Nebraska, operating out of 15 terminals around the country. It is among the top five trucking companies in the United States. This report examines the trucking industry and where Werner Enterprises stands within it, as well as Werner Enterprises’ competitive advantages, and how future challenges of the trucking industry may affect the company. The report utilizes a PESTEL and Porter’s Five Forces analysis to closer examine the external environment and industry Werner Enterprises operates in. Following this evaluation, recommendations are provided based on Werner Enterprises’ current positioning and future challenges in the trucking industry

The least squares process of MEDIA for computing DRVID calibration polynomials

A process is described and evaluated for computing a least squares polynomial approximation of data points in which the optimum degree of the polynomial is automatically determined. An iterative smoothing technique is used to replace every point with the value taken on by a moving least squares polynomial computed from a subset of points centered at the point to be replaced. The optimum degree of the resulting polynomial approximation is determined by analyzing the finite differences of each successive set of smoothed points. To evaluate the process, both artificially constructed data and actual Mariner Mars 1971 (MM'71) tracking data are used. This process was incorporated into a transmission media calibration computer program (MEDIA), which calibrates radiometric data to overcome the effects on the tracking signal of charged particle media. MEDIA was used in support of MM'71

PART I. ELECTROPHILE STRUCTURE AS A FACTOR IN ALKYLATIONS OF CAMPHOR DERIVATIZED GLYCINATES. PART II. PUMMERER REACTIONS OF S-OXIDES OF 1,3-OXATHIOLAN-5-ONES AND 1,3-THIAZOLIDIN-4-ONES.

Part I. Alkylation reactions of the camphor imine of t-butyl gly- cinate 1 were found to proceed with varing amounts of diastereo- facial selectivity depending on the electronic nature of the alkylating agent. Saturated alkyl halides gave diastereomeric excesses up to 67%. Allylic and benzylic alkylating agents reacted to provide diastereomeric excesses up to 98%. A transition state model which involves a favorable electronic interaction between the pi system of the alkylating agent and the lithium enolaate has been proposed to explain the enhanced diastereoselectivities observed for these types of alkylating agents. (DIAGRAM, TABLE OR GRAPHIC OMITTED...PLEASE SEE DAI) (UNFORMATTED TABLE FOLLOWS) NCH(,2)CO(,2)t-Bu NCHCO(,2)t-Bu 1 R(TABLE ENDS) (1-Bromoethyl)benzene, 3-bromocyclohexene, and 5,5-dimethyl- 3-bromocyclohexene were found to react to give only two of the four possible diastereomers. It was determined that the stereochemically pure center of the products from these reactions was C-3 (by amino acid numbering). Palladium mediated allylation reactions of the sodium enolate of 1 were also possible. Part II. Attempts to capture the sulfur stabilized carbonium ion intermediate of the Pummerer reaction of 1,3-oxathiolan-5-ones and 1,3-thiazolidin-4-ones with olefins and benzene are described. The reactions were unsuccessful with the oxathiolanones studied. Substi- tutions at the 5-position of 3-methyl-1,3-thiazolidin-4-one have been achieved using trifluoroacetic anhydride as the catalyst. 5-Phenyl substitutions of all thiazolidinones were easily performed utilizing an excess amount of concentrated sulfuric acid as the catalyst. Aldol and alkylation reactions of the 3-methyl-thiazolidinone were also successful. Source: Dissertation Abstracts International, Volume: 47-09, Section: B, page: 3750.
