Development of a framework for obsolescence resolution cost estimation
No full textCurrently, manufacturing organisations worldwide are shifting their business
models towards Product-Service Systems (PSS), which implies the
development of new support agreements such as availability-based contracts.
This transition is shifting the responsibilities for managing and resolving
obsolescence issues from the customer to the prime contractor and industry
work share partners. This new scenario has triggered a new need to estimate
the Non-Recurring Engineering (NRE) cost of resolving obsolescence issues at
the bidding stage, so it can be included in the support contract. Hence, the aim
of this research is to develop an understanding about all types of obsolescence
and develop methodologies for the estimation of NRE costs of hardware
(electronic, electrical and electromechanical (EEE) components and materials)
obsolescence that can be used at the bidding stage for support contracts in the
defence and aerospace sectors.
For the accomplishment of this aim, an extensive literature review of the related
themes to the research area was carried out. It was found that there is a lack of
methodologies for the cost estimation of obsolescence, and also a lack of
understanding on the different types of obsolescence such as materials and
software obsolescence. A systematic industrial investigation corroborated these
findings and revealed the current practice in the UK defence sector for cost
estimation at the bidding stage, obsolescence management and obsolescence
cost estimation. It facilitated the development of an understanding about
obsolescence in hardware and software. Further collaboration with experts from
more than 14 organisations enabled the iterative development of the EEEFORCE
and M-FORCE frameworks, which can be used at the bidding stage of
support contracts to estimate the NRE costs incurred during the contracted
period in resolving obsolescence issues in EEE components and materials,
respectively. These frameworks were implemented within a prototype software
platform that was applied to 13 case studies for expert validation
Determination of nitrofurantoin drug in pharmaceutical formulation and biological fluids by square-wave cathodic adsorptive stripping voltammetry
No full textNitrofurnation is an antibacterial drug. It is used in the treatment of initial or recurrent urinary tract infections caused by susceptible organisms. The cyclic voltammogram of the drug in Britton-Robinson buffers (pH 2-11) exhibited a single well-defined cathodic peak at the hanging mercury drop electrode, that due to the reduction of its nitro group to the amine stage. A fully validated, sensitive, and reproducible developed procedure was described for determination of the drug in bulk form, pharmaceutical formulation, human serum and human urine using, square-wave cathodic adsorptive stripping voltammetry. The optimal experimental parameters for the drug assay were: accumulation POTENTIAL=?0.4 V (vs. Ag/AgCl/ KCls), accumulation TIME=40 s, FREQUENCY=120 Hz, pulse AMPLITUDE=50 mV and scan INCREMENT=10 mV in Britton–Robinson buffer (pH 10). A mean percentage recovery of 100.68 +/- 0.17 (n = 5) and a detection limit of 1.32 x 10(-10) M of bulk drug were achieved. Applicability to assay of the drug in pharmaceutical formulation, human serum and human urine was studied and illustrated. The mean percentage recoveries were found as: 101.49 +/- 0.65, 103.94 +/- 0.73 and 101.98 +/- 0.52 (n = 5) in pharmaceutical formulation, human serum and human urine, respectively. Detection limits of 2.86 x 10(-10) M and 5.77 x 10(-10) M nitrofurantoin were achieved in human serum and urine, respectively

Uncertainty challenges in service cost estimation for product- service systems in the aerospace and defence industries
No full textOrganised by: Cranfield UniversityContracting for availability is expected to become more prevalent for product -service systems (PSS) in the
aerospace and defence industries. These contracts tend to transfer responsibilities for the operational phase
from the customer to the supplier. In parallel, with operational life spans spanning several decades, the
ability to deal with uncertainty in cost estimation for support activities is becoming critical. This paper outlines
challenges within this process derived from literature as well as issues that were highlighted during
interviews with four major defence and aerospace organisations.Mori Seiki – The Machine Tool Compan

Dispelling the Myths Behind First-author Citation Counts
No full textWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
