In the past decade, academic world established a variety of fragile states
index systems. They were generally based on the evaluation of society, environment,
economy and government. Given that climate change has far-reaching impact for the
quality of humankind and the development of a country, we have reasons to believe
that climate change may have increased fragility of a country. We used analytic
hierarchy process and established fuzzy synthetic evaluation models to identify when
a sate is fragile, vulnerable, or stable. And we used the gray correlation method to
analyze the correlation between climate change and each evaluation indicators. Then,
we combined with Yemen's specific situation; we found that climate change makes its
more fragile through the impact to food production, water supply, natural disasters
and other evaluation indicators. We also demonstrated that Yemen will not become
so vulnerable without these adverse weather effects.

Big data can be defined as high volume, high velocity and high variety of
data that require high performance processing. Predictive modelling is a process of
creating a model to predict the future behavior from the data. A predictive model is
made up of predictors which are factors that influence future results. A Proposed
prediction model is identifies best prediction algorithm by evaluating the performance
of an algorithm. The model contains preprocessing module and predicting module
which trailed by performance evaluation to find best prediction algorithm. The
preprocessing module emphasizes flow of preprocessing methods. The prediction
module combines various efficient algorithms to prediction, amid them the best
prediction algorithm can be identified by performance evaluation measurement.

To model the milling process, you need an accurate model of the cutting
tool. The article presents a methodology developed for designing a part with
replaceable "end milling cutter" plates in a three-dimensional configuration. The
model of a "face milling cutter" type with carbide inserts includes a large number of
variables, such as diameter, number of teeth, their clearance angles, and the like.
Therefore, the geometry of such a cutting tool is chosen on the basis of similar details
studies. The proposed model was developed using the CAD system of SolidWorks.
The cutting insert deformation of the milling cutter in the SolidWorks Simulation
module is analyzed, as a result of the calculated cutting force acting on it, it is
determined that the cutting inserts meet the accuracy requirements for surface
treatment of grade 2-4.

Low Noise Amplifier (LNA) is generally the first stage in microwave
communication system. The quality factor of the receiver is greatly determined by the
performance of LNA. Design of a low noise amplifier (LNA) is a very critical as it
amplifies the received signal and contributes most of the noise figure of whole
receiver. LNA is an integral component of RF receiver and it performs various
functions i.e. amplification, noise reduction, Noise Figure reduction, better
stabilization and noise immunization. However, design of a LNA requires the tradeoff of many important parameters including gain, Noise Figure (NF), stability, power
consumption, cost and design complexity. In this paper, we have designed and
optimize the performance of a single stage stable LNA through an optimization
algorithm. Our optimized single stage LNA circuit provides a gain of 11.78 dB and
noise figure of 1.86 dB. These are the most important design parameter of a LNA. In
this design, a microwave BJT numbered AT3103 from Avago technologies was used.
The simulation and performance optimization was carried out in Agilent design
package Advance Design Systems (ADS). This LNA operates at center frequency of
2 GHZ and it can be used in L-Band satellite applications.

The Ritz method was used in this paper for the flexural analysis of a
statically indeterminate Euler – Bernoulli beam with a prismatic cross section. The
beam considered was a propped cantilever of length, l, fixed at x = 0, and simply
supported at x = l; and carrying a linearly distributed transverse load on the
longitudinal axis. Two cases of coordinate (basis) functions were studied. In the first
case, the basis functions were constructed to satisfy the deflection boundary
conditions, but not the force boundary conditions. In the second case, the basis
functions were constructed to satisfy all the boundary conditions. It was found that
the stiffness equations formed with the basis functions that satisfied all the boundary
conditions gave the exact solutions for deflection, bending moments and shear force
distributions along the beam’s longitudinal axis. The effectiveness of the Ritz method
for solving statically indeterminate Euler Bernoulli beam flexure problems was thus
highlighted.

Metrics are an important technique in quantifying desirable software and
software development characteristics of aspect oriented software development
(AOSD). Theoretical and empirical validation of metrics and of their relation to
software attributes is a cumbersome and long process. It is of paramount importance
that we validate the utility of metrics we use in order to enable others to use them,
too. Aspect oriented programming is an efficient approach to improve the software
program at the time of software maintenance for modularizing crosscutting concerns.
However, in order to take the advantages of AOP, there is a need for supporting the
systematic refactoring of crosscutting concerns to aspects. This paper presents a new
cognitive complexity metric namely Cognitive Weighted Number of Children for
measuring coupling in Aspect Oriented Software.

Indonesia's chemical industry is faced with the challenge of increasing its
supply chain competitiveness, while the chemical industry in Indonesia generally still
does not have a holistic performance measurement system in its supply chain. The
objective of this research is to develop the framework of supply chain performance
measurement of the chemical industry using SCOR and DMAIC models. The
research stages are the selection of chemical industry supply chain indicators,
benchmarking of indicators, development of the framework for supply chain
performance measurement for Indonesia’s chemical industry, and the improvement of
the supply chain performance. The implementation was carried out at the cases in the
market leader company which produces textile dyes product in Indonesia. The result
of expert consensus recommends 28 indicators of the industrial chemical supply
chain. The best in class for each supply chain performance indicator become the
performance target on the performance measurement framework which is developed.
The results of measuring the performance of the chemical industry supply chain in
the textile dyes product showed good performance at flexibility aspect, medium at
cost, reliability, and asset management cost aspect, and low at responsiveness aspect.
There were three critical to quality (CTQ) for responsiveness aspects; these are
demand analysis, raw material issue, and breakdown machine. The recommended
improvements are to provide training on demand analysis, to improve communication
with the regional party, to provide alternative vendors, raw material scheduling,
procurement of buffer stock for raw material critical, and scheduling preventive
maintenance.

Combining with the actual conditions of Venezuela, we apply fuzzy
synthetic evaluation models based on analytic hierarchy process to calculate the
tipping point that makes the country fragile. Then, we establish a gray forecasting
model and predict that the climate change will push the country to more fragile by
indirectly affecting food production, water supply, natural disasters and economy in 3
years. Finally, we have reason to believe that the government can effectively mitigate
the impact of climate change on the state fragility through some human intervention.

More than 2 billion people in the world today suffer from micronutrient
deficiencies caused largely by a dietary efficiency of vitamins and minerals. The
public health importance of these deficiencies lies upon their magnitude and their
health consequences, especially in pregnant women and young children, as they
affect fetal and child growth, cognitive development and resistance to infection.
Although people in all population groups in all regions of the world may be affected,
the most widespread and severe problems are usually found amongst resource poor,
food insecure and vulnerable households in developing country. Some efforts that
have been done to solve the problem such as micronutrient fortification in rice,
because it is the staple food consumed by more than 90% Indonesia’s population. The
objectives of this research were determined and evaluated the stability of
micronutrient level during rice fortification and cooking. The results showed that
micronutrients decreased during rice fortification and cooking. The raw-fortified rice
contained 38.52 - 59.91mg/L of iodine, 0.92-1.79mg/L of vitamin A and15.64 -
48.39 mg/L of iron depending on the concentration of the coating material used.
After cooking, the fortified rice contained 3.00- 3.93mg/L of iodine,0.43 - 1.0 mg/L
of vitamin A and 12.92-19.66 mg/lof iron. The levels of micronutrients,
although experienced significant losses, still meet the daily needs according to the
Regulation of World Health Organization.

Buildings in hot countries experience significant amount of heat gain
through windows and this affects the thermal comfort of buildings' occupants. The
proposed glazing is specially designed to reduce the electricity consumption for
lighting and cooling. The optical properties of the glazing have been optimized by
using rigorous coupled-wave analysis method. The glazing consists of ITO and four
periodic pairs of Si/SiO2, deposited on a glass sheet. The fabrication of the glazing
and the testing has been performed at the laboratories of the Faculty of Science,
University of Witwatersrand, South Africa. Magnetron sputtering technique has been
used for the fabrication. The optimum thicknesses of ITO, Si and SiO2, obtained from
the simulation and the experimental work, are 0.1 μm, 0.15 and o.4 μm, respectively.
The glazing transmits 70-80% of the visible light and reflects almost all the infrared
radiation.
