Automatic building change detection required for metropolitan and urban
planning , industrial city planning, road and highway planning, unauthorized
construction detecting, stopping any new construction on risky or highly dense areas,
planning for homeland security etc. This research proposal aims for automatic
building change detection and 3D map generation using multispectral imagery and 3-
dimentional height data. The goal for this research proposal is to detect building
changes with precise geometric accuracy and use the detected building changes data
to generate 3D building map. High resolution aerial and satellite imagery and highly
dense height data from LIDAR can detect building change and can generate an
accurate up-to-date 3D building map.

By studying quantum state, quantum state spaces as well as multiple qubits
of quantum mechanics, it is found that an active path finding robot can be designed
on the basis of quantum mechanics. To begin with, quantum encoding, quantum logic
gates, quantum logic circuit, quantum gate arrays and quantum parallelism are
studied. Then a robot on the basis of quantum bits is designed. Finally, an active path
finding algorithm on the basis of quantum fourier transforms and related pathing
finding algorithm are found. Meanwhile, some examples and related analyses
indicate that an active path finding robot on the basis of quantum mechanics is
feasible.

River bank erosion has always been a challenging problem in Bangladesh.
Conventional method of designing erosion protection structures are governed by the
hydraulic loads resulting from currents and waves. In practice, toe protection
elements are dumped into flowing water and settle somewhere on the river bed to
form an apron. The present study has been undertaken to investigate experimentally
the aspect of underwater threshold condition of toe protection elements. The
experiments are conducted in the large tilting flume of the Hydraulics and River
Engineering Laboratory of Water Resources Engineering Department, BUET. Cubeshaped Concrete Block (CC block) is considered as erosion resistant material. A
geometrically similar undistorted scale factor of 20 has been selected to conduct the
experiment. Hydraulic parameters and CC block are selected based on typical field
condition and the experiment is designed according to the scale. Two different initial
water level (set-up 1 and set-up 2) is deliberated for the same size of CC block to
investigate the hydraulics of threshold characteristics. During experimentation
various observations are made and the measured data are used to analyze various
hydraulic features of threshold condition. Gradual smooth increment of flow is
ensured to reach threshold condition. At this stage, water level is 0.212 m, section
average velocity is 0.55 m/s and depth averaged velocity is 0.54 m/s for set-up 1.
While for set-up 2, water level is 0.256 m, section average velocity is 0.54 m/s and
depth averaged velocity is 0.53 m/s. Though the threshold velocity magnitude for setup 1 and set-up 2 are very close, the corresponding water level is quite different since
initial depth of flow is different. It is expected that the results obtained here can be
useful to develop predictive expression for estimating the threshold velocity of CC
blocks. Scope of detailed analyses in this area of interest is in progress.

In this study EPANET, a widely used water distribution package was
linked to OptiGa, a Visual Basic ActiveX control for implementation of genetic
algorithm, through Visual Basic programming technique, to modify the computer
software called OptiNetwork. OptiNetwork was applied to Badarawa / Malali
distributionnetwork consisting of 96 pipes of different materials, 75junctions, two
tanks, and a source reservoir (i.e treatment plant) from which water is pumped
through a pumping main to the overhead reservoir and later distributed to the
network by gravity. After several runs the cost obtained from this network using
OptiNetwork software under the application of genetics algorithm is
$433,520.00which is lower than $435,118.00 obtained from OptiDesigner software.
This difference is approximately 3% lower than the result obtained from
OptiDesigner (a commercial software) with minimum pressure head of 3m and
maximum of 100, Pressure penalty of 200,000 and probability of mutation equal to
0.03, also the commercial diameters of 4”, 6”, 8”, 10”, 12”, 14”, 16” 18” 20’’,
22’’and 24’’ dmin =4”, dmax = 24” were used for the distribution network during
the optimization process. The results obtained shows that the introduction of the
modified software (OptiNetwork) is justified. This is because it has been able to
improve the search method in terms of achieving the “least-cost” designed water
distribution system that will supply sufficient water quantities at adequate pressure
to the consumers.

This paper critically reviews methods applied in forecasting production of
unconventional gas plays. The review focuses on methodologies suitable for shale gas
plays, methodological ability to account for parameter and data uncertainty, as well as
suitability for appraising undeveloped shale gas plays. The production analysis and
forecast methods reviewed include empirical/decline curves, type curves and
analytical/numerical methods applicable to unconventional gas production analysis
and forecast. The review shows that most of the studies focus on developed shale gas
plays, neither account for shale gas well reservoir heterogeneity nor account for
below ground uncertainties-such as reservoir and source rock properties. This study
concludes that significant research is needed to address the identified limitations of
existing studies.

A new method for preconcentration of ultratrace amounts of Co (II), Ni(II)
and Cu(II) ions in various matrices has been proposed. The method is based on the
adsorption and chelation of the metal ions on Amberlite XAD-4 resin modified with
Quinol via azotisation prior to their determination by standard spectrophotometric
method. The effect of pH, type, concentration and volume of eluent, sample
volume,flow rates of sample and elution solutions, and interfering ions have been
investigated. The optimum pH for retention of the metal ion were10.0, 7.0 and 7.0
respectively. Eluent for quantitative elution was 5 ml of 2 mol l−1 HCl. The optimum
sample and eluent flow rates were found to be 2.5 ml min−1. The sorption capacity of
the resin was found to be 0.60, 0.45 and 0.52mmolg-1 for Co (II), Ni (II) and Cu (II)
respectively. The preconcentration factor of the method was 250 for all the metals.
The detection limit values were in the range of 3.0- 5.0 µgl-1. The accuracy of the
method was confirmed by analyzing standard synthetic mixtures and standard
addition methods. This procedure was applied to the determination of Cobalt, Nickel
and Copper from various water samples and SRM’s.

The historical weather datasets of different locations of India were complied
for solar radiation, maximum and minimum temperatures and sunshine hours. Solar
radiation is vital parameter, measured only at 35 meteorological stations all over the
India. Our country, with diverse agro climatic zones, although covered by huge network
of 550 Automatic Weather Stations but still faces the problem of acquisition of data
related to key meteorological parameters. This paper aims to calibrate the coefficient of
two equations: 1) Angstrom Prescott Equation [Rs= (a+b*n/N) Ra], which has input of
sunshine hours data 2) Supit–Van Kappel Equation [H=Ho (a √Tmax-Tmin +b√ (1-
Cw/8) +c), with the inputs of easily available temperature and cloud cover data, on the
basis of 25 stations all over India representing diverse agro climatic zones. Extrapolation
technique was used for the stations that are located within radius of 200 km. The
relationship of solar radiation with square root of the difference in maximum and
minimum temperatures was significant. The northern region showed greater range of
predictability, i.e. 0.43 to 0.86 in winter; 0.19 to 0.82 in pre monsoon; 0.25 to 0.84 in
monsoon and 0.40 to 0.89 in post monsoon which was statistically significant. The
degree of prediction was higher for locations in northern and western regions, which
was poor for all location in southern and eastern regions. The transmissivity of the
atmosphere for global solar radiation under perfectly clear sky conditions is given as the
sum of the regression coefficient a & b of Angstrom Prescott Equation. Also, the
transmissivity of an overcast atmosphere is interpreted as the value of the intercept, a.
From our regression constants (a = 0.23 and b = 0.38), it is observed that the
atmospheric transmissivity under clear skies is 0.61. This result compares well with the
value of 0.67 to 0.70 reported for the humid tropics [4]. The clear-sky transmissivity of
most tropical regions in general seems to lie between 0.68 and 0.75 [1, 8].

PT Nexus Fashion & Sports is a manufacturing industry that produces work
gloves and sports. The company's current production system has not been able to run
effectively and in balance because production demand and production planning always
change. Applying the right production system can provide the right production process.
The Toyota Production System (TPS) can help companies cope with demand fluctuations
and control production planning in a controlled manner. The basis for the implementation
of TPS is the principle of heijunka, namely the fundamental removal of mura, muri, and
muda. This study aims to measure the effectiveness of the production process and design
the TPS based on the principle of heijunka to improve the productivity of human labor.
Analysis of production process effectiveness using manufacturing cycle effectiveness
(MCE) method was 67% and improvement proposal was 69%. Production rate balancing
(mura) on production scheduling of TPS design based on heijunka principle using mixed
model scheduling method produces daily flat based production. Alignment of workload
(muri) using work load analysis method in March and April 2017 TPS design based on
the principle of heijunka there were advantages of 1 person and 4 people. The average
human work productivity of TPS design based on heijunka principle increased by 1.10%.
