A large number of road accidents and major road fatalities occur in
Singapore each year. To lessen the same scenerio the factors must
be clearly identified. Proper relationship must need to derive to
know the magnitude of each factor in occurring road accidents. Both
qualitative and quantitative factors have influence in occurring
road accidents and road fatalities. The qualitative factors include
the lack of traffic education and enforcement, drink-driving,
speeding, red-running, hand phone driving, lack of training for
motorcyclists, lack of campaign and so on. Though a big portion of
road accidents are being occurred by the qualitative factors, it is
very difficult to quantify them all with some numeric value. But
there are still big portions of road accidents are being occurred
each year by some quantitative factors. So, the existing study is
designed only to distinguish the influential behavior of some
quantitative parameters. It is assumed that the quantitative
factors may have some influence on road accidents and road
fatalities. So, some selected quantitative parameters will be
examined by all possible regressions approach to investigate for
linear relationships among them.
Presently, Infrastructure management becomes the top priority of
each government body to provide the best quality life to its
citizens. However, due to lack of resources and rapid population
growth, a big share of its citizens are deprived from their basic
services. The most common services that are expected to provide
from the government bodies includes education, utilities,
recreational facilities, community services etc. Due to unplanned
distribution of its resources, some regions are overly served
whereas other regions have no accessibility to those services.
Hence, it is utmost importance to formulate the policy to have
equivalent access to each facility or service in terms of travel
time or distance, travel cost, comfort etc. As a case study,
Rajshahi City Corporation Area has been considered to analyze the
performance of its public services using geospatial data and the
policy and recommendations have been drawn.
Bangladesh is a developing country which is incorporated with
numerous resources like land, water, people also. Here majority of
people live in rural areas and their life is dependent on some
valuable agricultural land which is their main earning source. But
this land area is being decreasing and population is increasing day
by day. The new pressure is being created on agricultural land
area. In this study, Compact township approach has been taken as a
study topic aiming to incorporate all the rural settlement in one
place where all the urban facilities and service like water supply,
electricity, gas, education would be provide and previous homestead
area would be treated as agricultural land. In addition, their
employment generation place would be near to the homestead area. By
considering this option the study area has been selected P uti a
Union, S hibpur, Narsingdi Dist rict. B y conducti n g a household
's questionnaire survey, an additional official survey and some
group discussion their existing social, physical, economic,
environmental condition has been known.
Bangladesh is a developing country with a per capita GDP of
approximately US$500 per annum. The country's economy is mainly
based on agriculture. However, this scenario has gradually been
changing since 1990. A construction boom started in the country
after 1990 owing to the necessity for industrial buildings,
corporate offices, housing units, roads and other types of
infrastructure. Bangladesh has made major progress in recent years,
with sustained macroeconomic stability. The Government of
Bangladesh has been pursuing a policy of promoting a competitive
market-based economy through financial and industrial policy
reforms, as well as trade liberalization.Major challenges faced by
the Bangladesh construction sector in this context relate to how to
improve the local technological capacity through technology
transfer, enhance competition in the domestic market and improve
the competitiveness of domestic enterprises through efficiency
gains. In this book the key strengths, weaknesses, opportunities
and threats for Bangladesh construction industry are identified.
The business process for local and foreign firms are included with
an emphasis on methods of tendering and taxation process.
A collocation meshless method is developed for the numerical
solution of Partial Differential Equations (PDEs) on the scattered
point distribution. The meshless shape functions are constructed on
a group of selected nodes (stencil) arbitrarily distributed in a
local support domain by means of a polynomial interpolation. This
shape function formulation possesses the Kronecker delta function
property, and hence many numerical treatments are as simple as
those of the Finite Element Method (FEM). Nearest neighbor
algorithm is used for the support domain nodes collection and a
search algorithm based on the Gauss-Jordan pivot method is applied
to select a suitable stencil for the construction of the shape
functions and their derivatives. This search technique is subject
to a monitoring procedure which selects appropriate stencil in
order to keep the condition number of the resulting linear systems
small. Various meshless collocation schemes for the solution of
elliptic, parabolic and hyperbolic PDEs are investigated for the
proposed method. Different types of PDEs are studied as test cases
and all of the computational results are examined.
The green plant cover of highly populous Bangladesh is degrading
rapidly. Lack of knowledge on flowering and fruiting seasons of
plants is partly responsible for this situation. Fruit-eating
birds, the agents for seed dispersal and germination, are also
important. In this study, the fruiting season, fruit color spectra,
avian frugivore diversity, avian frugivores relationship with fruit
size, foraging and fruit handling techniques were documented. Both
the fruiting season and Fruit-eating birds in a mixed evergreen
forest of Bangladesh were focused to understand the contribution of
these biological agents in a ecosystem.
