Exact Wavefunctions for a Delta Function Bose Gas with Higher Derivatives

A quantum mechanical system describing bosons in one space dimension with a kinetic energy of arbitrary order in derivatives and a delta function interaction is studied. Exact wavefunctions for an arbitrary number of particles and order of derivative are constructed. Also, equations determining the spectrum of eigenvalues are found

An Econometric Analysis of the Effects of Climate Change on Arable Crop Production in Botswana from 1980-2008

Climate variability and change have been implicated to have had significant impacts on global and regional food production particularly the common stable food crops performance. However, the extent and nature of these impacts still remain are uncertain. In this study, records of crop production (maize and sorghum), climatic variables and non-climatic variables were used to carry out a comprehensive study of the effects of climate change on arable farming in Botswana. It estimates the effect of random year-to-year variation in weather on agricultural output using a 28-years district-level panel data. Crops differed markedly in their responses to the climate variables. Maize production performed badly compared to sorghum which proved to be drought resistant and performed very well under the climate environment of Botswana.  The results further showed that the inclusion of area planted is very important in this analysis. When considering area planted as an exogenous explanatory variable, we found a monotonic positive relationship between the production of maize and sorghum with area planted, indicating that economies of scale are dominant throughout the plot size distribution. In general, the analysis indicated that increasing temperature and decreasing rainfalls are both damaging to Botswana’s agriculture. These results suggest that climate change is likely to impose significant costs on the Botswana economy unless farmers can quickly recognize and adapt to increasing temperatures. Such rapid adaptation may be less plausible in a developing country, where access to information and capital is limited. Even though the analysis did not incorporate the carbon fertilization effect or the role of technology and change in prices for the future, significant information for policy making can be extracted. By filling these gaps, more information for decision making can be generated. Keywords: climate change, Botswana, arable farming, panel dat

Impact of the Extended Marketing Mix elements on Customer Service in the Insurance industry in Botswana

Excellent insurance companies are blending all the 3Ps of services marketing in their marketing activities to retain existing customers as well as to attract potential ones. This study has put efforts to investigate the impact of the extended marketing mix elements on customer service in the insurance industry in Botswana.  The objective of this study was to establish if there is a relationship between the extended marketing mix elements and customer service. Causal research design was employed and the questionnaire was used to collect the data. Data was analyzed using descriptive and inferential statistics. The study revealed that there is strong positive correlation between the extended marketing mix elements on customer service. Customers expect a high level of service delivery from the insurance companies.  The study concludes that insurance companies should invest in training its personnel mainly on the products offered by the company. Insurance companies should automate their processes and continue to improve the service escapes to attract and retain clients. Keywords: Extended marketing Mix, Customer Service, Service Qualit

Two-photon absorption in potassium niobate

We report measurements of thermal self-locking of a Fabry-Perot cavity containing a potassium niobate (KNbO3) crystal. We develop a method to determine linear and nonlinear optical absorption coefficients in intracavity crystals by detailed analysis of the transmission lineshapes. These lineshapes are typical of optical bistability in thermally loaded cavities. For our crystal, we determine the one-photon absorption coefficient at 846 nm to be (0.0034 \pm 0.0022) per m and the two-photon absorption coefficient at 846 nm to be (3.2 \pm 0.5) \times 10^{-11} m/W and the one-photon absorption coefficient at 423 nm to be (13 \pm 2) per m. We also address the issue of blue-light-induced-infrared-absorption (BLIIRA), and determine a coefficient for this excited state absorption process. Our method is particularly well suited to bulk absorption measurements where absorption is small compared to scattering. We also report new measurements of the temperature dependence of the index of refraction at 846 nm, and compare to values in the literature.Comment: 8 pages. To appear in J. Opt. Soc. Am.

Statistical correlation of structural mode shapes from test measurements and NASTRAN analytical values

The software and procedures of a system of programs used to generate a report of the statistical correlation between NASTRAN modal analysis results and physical tests results from modal surveys are described. Topics discussed include: a mathematical description of statistical correlation, a user's guide for generating a statistical correlation report, a programmer's guide describing the organization and functions of individual programs leading to a statistical correlation report, and a set of examples including complete listings of programs, and input and output data

Fiber-optic three axis magnetometer prototype development

The goal of this research program was to develop a high sensitivity, fiber optic, interferometric, three-axis magnetometer for interplanetary spacecraft applications. Dynamics Technology, Inc. (DTI) has successfully integrated a low noise, high bandwidth interferometer with high sensitivity metallic glass transducers. Also, DTI has developed sophisticated signal processing electronics and complete data acquisition, filtering, and display software. The sensor was packaged in a compact, low power and weight unit which facilitates deployment. The magnetic field sensor had subgamma sensitivity and a dynamic range of 10(exp 5) gamma in a 10 Hz bandwidth. Furthermore, the vector instrument exhibited the lowest noise level when only one axis was in operation. A system noise level of 1 gamma rms was observed in a 1 Hz bandwidth. However, with the other two channels operating, the noise level increased by about one order of magnitude. Higher system noise was attributed to cross-channel interference among the dither fields
