Charge Symmetry Breaking in 500 MeV Nucleon-Trinucleon Scattering
Elastic nucleon scattering from the 3He and 3H mirror nuclei is examined as a
test of charge symmetry violation. The differential cross-sections are
calculated at 500 MeV using a microsopic, momentum-space optical potential
including the full coupling of two spin 1/2 particles and an exact treatment of
the Coulomb force. The charge-symmetry-breaking effects investigated arise from
a violation within the nuclear structure, from the p-nucleus Coulomb force, and
from the mass-differences of the charge symmetric states. Measurements likely
to reveal reliable information are noted.Comment: 5 page
Criteria of Nonacademic Characteristics Used to Evaluate and Retain Community Counseling Students
The authors investigated ways in which selected 2001 standards of the Councii for Accreditation of Counseling and Related Educational Programs, namely, retention and evaluation criteria relative to nonacademic characteristics, are addressed within Community Counseling master\u27s-degree programs. Results from this survey research study illustrated various retention criteria that are used to evaluate students in various community counseling programs across the country
Atomic Properties of Lu
Singly ionised Lutetium has recently been suggested as a potential clock
candidate. Here we report a joint experimental and theoretical investigation of
\ce{Lu^+}. Measurements relevant to practical clock operation are made and
compared to atomic structure calculations. Calculations of scalar and tensor
polarizabilities for clock states over a range of wavelengths are also given.
These results will be useful for future work with this clock candidate.Comment: 12 pages, 5 figure
Comparison of the Aggregate Production Planning for Low-Demand Products in an MTO and MTS Systems Based on Linear Programming in the Ceramic Industry
The aggregate production planning for low-demand items in a ceramic company is based on a Make-to-order (MTO) policy (no inventories are allowed). The production scheduler receives forecasts for the next 12 months and must develop an updated master production schedule to meet all requirements. Plaster moulds are required to produced finished goods. Due to the lack of mould storage capacity in the plant, after fulfilling demand, the required plaster moulds must be scrapped, incurring in high manufacturing cost. Thus, in this project, a reduction of mould production is proposed through a Make-to-stock (MTS) system, where holding inventory for low-demand items is allowed. A linear programming model is formulated with the objective of minimise total operational costs; mould production costs, inventory costs, setup costs and penalty costs. The model shows an optimal production schedule, and we compare it with the current MTO approach. Despite a significant increase in holding costs is found, the reduction in the remaining costs result in the saving of 7.51% from the total costs. The model allows to meet current market demand forecasts in a short time, but in the case of an unexpected order, the customer will have to be granted a lead time according to the time needed to complete this requirement. For further research, goal programming method can be applied in order to seek more goals to achieve

Experimental laboratory system to generate high frequency test environments
This is an extension of two previous analytical studies to investigate a technique for generating high frequency, high amplitude vibration environments. These environments are created using a device attached to a common vibration exciter that permits multiple metal on metal impacts driving a test surface. These analytical studies predicted that test environments with an energy content exceeding 10 kHz could be achieved using sinusoidal and random shaker excitations. The analysis predicted that chaotic vibrations yielding random like test environments could be generated from sinusoidal inputs. In this study, a much simplified version of the proposed system was fabricated and tested in the laboratory. Experimental measurements demonstrate that even this simplified system, utilizing a single impacting object, can generate environments on the test surface with significant frequency content in excess of 40 kHz. Results for sinusoidal shaker inputs tuned to create chaotic impact response are shown along with the responses due to random vibration shaker inputs. The experiments and results are discussed. 4 refs., 5 figs
