Author, publisher and bookseller : a tripartite synergy in Nigerian book industry
No full textThis work is about the roles of Author, Publisher and Bookseller in Book development in
Nigeria. The paper started by delving into the history of Book Publishing in Nigeria after
which it proceeded by defining who an author, a publisher, and a bookseller is and
expatiated on the indispensable roles of these key actors in Nigerian Book Industry and in
the emerging Information Society. Furthermore, the various constraints to book
development were identified while the paper advised on how the Book Industry can be
further promoted in Nigeria. However, the paper concluded and made recommendations
on how the Book sector can help in enhancing scholarship in the country

Geographic profiling in Nazi Berlin: fact and fiction
No full textGeographic profiling uses the locations of connected crime sites to make inferences about the probable location of the offender’s ‘anchor point’ (usually a home, but sometimes a workplace). We show how the basic ideas of the method were used in a Gestapo investigation that formed the basis of a classic German novel about domestic resistance to the Nazis during the Second World War. We use modern techniques to re-analyse this case, and show that these successfully locate the Berlin home address of Otto and Elise Hampel, who had distributed hundreds of anti-Nazi postcards, after analysing just 34 of the 214 incidents that took place before their arrest. Our study provides the first empirical evidence to support the suggestion that analysis of minor terrorism-related acts such as graffiti and theft could be used to help locate terrorist bases before more serious incidents occur
Assessing measurement system acceptability for process control and analysis using gage R&R
No full textPlan BGage R&R, which stands for gage repeatability and reproducibility, is a statistical tool that is applied to measure the amount of variation in the measurement system which arises from the people taking the measurement and the measurement device. The purpose of conducting the GR&R is to quantify measurement error and to reduce the measurement system variation if it is excessive. In a typical gage R&R study, several operators each measure a selected set of items more than once. This study is pursued in a large-scale manufacturing plant in western Wisconsin in order to evaluate the capability of a set of new measurement equipment that is just purchased by the company. Some potential problems related to the measurement system might be exposed after this study and recommendations would be made in order to achieve a successful quality improvemen
Design and Development of a Date Harvesting Machine
No full textExisting date harvesting machines are vehicles equipped with a long arm to lift a man
on a platform to harvest the fruits. The arm and the vehicle are heavy (4 to 8 tonnes),
expensive (from £16 000) and are not sufficiently manoeuvrable in constricted date
groves. Most dates in the main producing countries, including Iran, are therefore
harvested manually. The manual method is unsafe, slow, expensive (£0.63 per tree)
and the fruit quality is often damaged.
A light, weight 4 wheel drive, remotely controlled tree climbing machine is, therefore,
a potential solution to the problems of harvesting and servicing (such as pollinating
and pruning). A prototype of such a device was designed, developed and evaluated
under laboratory conditions. To determine the operating characteristics and feasibility
the machine was designed to climb the tree using pneumatic tyres as traction wheels.
The machine can be transformed to ground drive and move between trees under its
own power. This approach reduces the machine weight, cost and size because the
tree trunk is used as a support for the machine to climb to the fruits. It is operated
and controlled from the ground which improves the operator safety.
A vertical traction theory for this type of machine has been developed based on the
tree size and surface characteristics and machine size and weight which can be used to
design date harvesting and climbing machines with different capacities. The test
results showed that the experimental machine could achieve a tractive efficiency of
90% and that the optimum wheel slippage was between 10 - 15%. The machine
consumes a maximum of 1.4 kW power which is only 3% of the power requirement
of existing systems. The machine weight is 150 kg which is 2- 4% of the existing
systems' weight. It is capable of climbing the tree at a maximum speed of 0.27 m/s
although the optimum speed is 0.17 m/s for best control. The prototype can carry a
payload of 100 kg of dates and, considering a field efficiency of 75%, it can
potentially harvest a tree in 22 minutes which is 18 % faster than the manual system in Iran and 6% faster than one of the mechanised systems used in Saudi Arabia. The
harvester can work on tree diameter ranges from 300 to 850 mm and can pass over
the tree leaf bases of 41 mm high. The machine should not damage the tree because
the tree resists the machine stresses with a minimum safety factor of 7.
An economic analysis showed that it can be manufactured in Iran at 20 % of the cost
of existing systems. The machine cost per tree is equal to the hand harvesting method
(£O. 63 per tree) for Iranian farmers if it harvests 978 trees per year
Central Australian date industry: a strategy for development
No full textMade available by the Northern Territory Library via the Publications (Legal Deposit) Act 2004 (NT).This report is intended to give a more detailed assessment of climate and water resources in potential development areas for date production. It documents research undertaken and observations made during the 1991-92 date season, then makes specific recommendations to encourage development of a Central Australian date industry.Introduction -- Climatic requirements of the date palm -- Phenology of recognised date varieties -- Potential areas for date production -- Research to support development of a date industry -- Conclusion and recommendations: a strategy for development -- References
Computational evaluation of the periodic performance of a NACA 0012 fitted with a Gurney flap
No full textA detailed computational investigation into the periodic two-dimensional performance of a NACA 0012 section fitted with 2 and 4 percent h/c Gurney flaps operating at a Reynolds number of 0.85×106 is presented. The aim of the work was to determine the suitability of the incompressible Reynolds-averaged Navier-Stokes (RANS) formulation in modeling the vortex shedding experienced by lifting sections with blunt, sharp edged features. In particular, whether under-converged steady state calculations could be used for section design performance evaluation in place of the computationally intensive time accurate flow simulations. Steady, periodic, and time-averaged two-dimensional lift and drag coefficients, as well as vortex shedding frequency, were predicted and compared with the available experimental data. Reasonable agreement was found, once sufficiently fine grids had been generated, and the correct time step determined for the time accurate simulations
