Author (s): |
Alein J. S., Yeturi Pramod Kumar Reddy,
Vasugi K. and S. Elavenil |
Abstract: |
The
use of in-filled columns is a new trend in composite construction
industry. The bearing capacity is more than the sum of individual load
carrying capacity of the stainless steel tube and concrete. In this
paper the austenitic stainless steel tube of 304 grade is used. The
conventional concrete is replaced by using geopolymer concrete as an
infill material. A stainless steel tube of various thickness is used as
a major parameter in this experimental investigation. The behavior of
infilled stub column and hollow stub column is studied experimentally by
applying gradual load along with analytical study using finite element
software ANSYS. The design strength of the composite stub column was
predicted by carrying out numerical investigation using various
international codes. The ultimate load carrying capacity of the infilled
stub column was calculated by experimental and analytical work and the
results of the same were compared for numerical simulation. The results
based on strength parameters were directly proportional to the thickness
of the material used. |

Title: |
Development of diesel piezo injector
driver using microcontrollers |
Author (s): |
Youngju Lee and Choong Hoon Lee |
Abstract: |
A
diesel piezo injector driver was developed using microcontrollers and
MOSFETs. Fuel injection with a common rail injector is possible when
controlling the magnitude of the hydraulic pressure acting on the nozzle
needle. There are two types of solenoids and piezo-electric components
to open and close the hydraulic passages acting on the nozzle needle. A
solenoid-type injector is driven by controlling the current waveform
supplied to the injector via a peak & hold approach. The solenoid-type
injector driver can be implemented with a circuit that switches the
driving power with one transistor which has a high current capacity. In
contrast, a piezo-type injector is driven by the contraction and
expansion of piezoelectric elements that open and close the hydraulic
passages to control the movement of the nozzle needle. In order to
control the contraction and expansion of the piezoelectric element in a
piezo injector, charge and discharge control of the current supplied to
the injector is required. For this purpose, a pair-switch circuit
capable of charging and discharging the current supplied to the injector
has been developed. The driving voltage of the piezo injector was in the
range of 100 ~ 140V. High voltage and current switches were used for
charging and discharging. Fuel injection at a high common rail pressure
was possible with higher driving voltage supplied to the piezo injector.
The control signal supplied to the MOSFET (IRF640N) is generated with
the output pin or CCP pin of an 8-bit microcontroller PIC16F917. The
common rail pressure was controlled by supplying square waves while
varying the duty ratio of the control signal. The microcontroller's
capture compares PWM (CCP) pins outputs the control signal. When the
duty ratio of the PWM square wave supplied to the rail pressure
controller is increased, the common rail pressure is decreased. |

Effect of bacillus subtilis on mechanical
behavior of bacterial concrete |
Author (s): |
C. Venkata Siva Rama Prasad and T. V. S.
Vara Lakshmi |
Abstract: |
In
the recent past bacterial concrete has been emerged as remedial measure
of healing cracks in structures like bridges, RCC Buildings, RCC Pipes,
Canal Lining, Pavement etc. Crack formation is incredibly common
occurrence in concrete structure that permits the water and completely
different sort of chemical into the concrete through the cracks and
reduces their strength and that additionally have an effect on the
reinforcement once it comes contact with water, carbon dioxide and
different chemicals. For repairing the cracks occurred within the
concrete, it needs regular maintenance and special sort of treatment
which can be terribly expensive. So, to solve this problem Henk Jonkers
introduced bacterial concrete to repair the cracks occurred in the
concrete structures. This research has demonstrated that particular
types of microorganisms can really be useful method to repair cracks in
the existing concrete structures. In this paper, experimental
investigation done to arresting the cracks in the concrete using
bacillus subtilis bacteria and calcium lactate. The selection of
bacteria depends on its survival in alkaline environment. In this study
bacillus subtilis bacteria with calcite lactate is used in different
percentages such as 5%, 10%and 15% of cement weight for M20 and M40
grade concrete. An empirical relation between flexural strength and
compressive strength is proposed in the form of ft = 0.66 vfck. |

Title: |
A review: The effects of particle
properties on solid particle erosion for oil and gas pipelines
applications |
Author (s): |
Dinesh Kanesan and Mysara Eissa Mohyaldin |
Abstract: |
The
production of sand along with hydrocarbons has been a major problem
faced by the oil and gas industry ever since the discovery of oil and
gas. The production of sand from the reservoirs may result in erosion,
accumulation, plugging and contamination by sand particles. Sand
particle erosion may lead to failure of piping components or equipment,
leaks in pipelines, and also hazard to personnel on site. Hence, the
prediction of solid particle erosion rate is critical in ensuring the
integrity of equipment and the safety of the system. Empirical models
are developed by performing experiments to measure erosion rate at
different particle properties and flow parameters. Particle properties
include particle size, shape and hardness. Any change in these
properties will result in a change in the erosion rate. In this review
paper, the findings of previous researchers on the effects of particle
properties on solid particle erosion rates were identified and reviewed.
In addition, the limitations in some of the research done were
highlighted to enable researchers to further study on the identified
areas. This current work would be beneficial to researchers who are
developing empirical models by identifying the key particle properties
to be included in their solid particle erosion prediction models. |

Estimation of harmonics using adaptive
wavelet neural network |
Author (s): |
M. Sujith and S. Padma |
Abstract: |
Increase in the power electronic devices had leads to the harmonic
contamination. Harmonic analysis is done to know about the origin and
cause of the harmonics in the power system. The low order harmonics is
monitored because these are very dangerous and cause serious power
quality issues. Wavelet networks (WNs) is an effective version of
nonlinear signal processing techniques in recent years an adaptive
wavelet neural network (AWNN) is the most appropriate for prevailing
low-order harmonics estimation. Odd-harmonic components of the
voltage/current signal are decomposed into the frequency bands by using
the above technique. Instead of one complete cycle data for estimating
the harmonics the proposed scheme only requires an only half-cycle data
point. The back propagation is used for training of the network
parameters which is a easy, fast converging and reliable learning
algorithm. The experimental signal which is obtained is examined with
the projected method. The output result conforms that AWNN technique is
effective in estimating the lower order harmonics, inter-harmonics if
they are deviated from the fundamental frequency. |

Villacanas and Jessica S. Velasco |
Abstract: |
The
demand for fish is continuously rising due to its high nutritional
value. Inexpert manual determination of fish freshness can cause false
assessment and result to the possibility of food poisoning. This study
developed an android application that automatically identifies the three
most consumed fish in the Philippines, namely milkfish, round scad, and
tilapia. Through image processing, the application classifies the
freshness of the fish from level 1 (stale) to level 5 (fresh) by using
the RGB values of the eyes and gills as well as determining its
remaining shelf life. The software was developed by iterative learning
of a feed forward neural network with 30 fish samples per species that
were used to obtain a total of 800 images each for the eyes and gills.
The results of the study showed that the device yields acceptable
results in identifying the fish and in determining its freshness. |

Abstract: |
Local
conditions wind multiplier map considered as one of the essential
supporting tool in windstorm disaster management because through this
map effected of local conditions to windstorm intensity (gust/wind
speed) in any grid area of 1 km x 1 km can be made known. Local
conditions multiplier for each grid area need to be multiplied with
predicted windstorm intensity from the source (downdraft) in order to
determine the actual intensity on land surface. Next, through the actual
intensity, potential damages can be identified. Information regarding
potential damages enables local authorities and public in the affected
area to make early preparation in minimizing the impacts caused by
windstorm occurrence. Production of this map is according to severe wind
gust risk assessment which taking into account of terrain (roughness),
shielding multiplier and topographic (hill-shape) factors. Multiplier
for each factor are based on the Malaysian Standard (MS1553: 2000) and
Australian/New Zealand standard (AS/NZS1170.2: 2011). Kuantan District
has been selected as a case study based on two factors, one of a
district in Malaysia with highest number of windstorm occurrences and
the only district that has been studied about its land cover roughness.
As a matter of fact, this article is to provide guidance in producing
supporting tool that could be as added value in windstorm disaster
management in the future. |

Title: |
Associative coprocessor block based on PLD
for different computer systems |
Author (s): |
Martyshkin A. I. |
Abstract: |
The
article considers the possibility of implementing an associative
coprocessor block on a modern element base for specialized computer
systems. The goal of the article is the development and study of the
associative co-processor block on PLD, for specialized computing, for
example, multi-processor, systems, performing associative function and
data storage functions. The object of research and development of this
article is the associative coprocessor based on PLD. The search
operation is widely used in different purposes as users and systems.
However, this operation is one of the most labor-intensive and requires
time-consuming when implemented in the traditional way, when the search
data is sequentially read from the machine RAM to the CPU, where they
perform the appropriate operation. The paper proposes associative
co-processor connected to the PCI bus of a computer system, providing
search and comparison of “more – less” simultaneously in 32 of said
pre-loaded in the associative memory. Finally, conclusions have been
made. The use of the VHDL language as a universal means of hardware
description of integrated circuits provides the flexibility of the
project and the ease of debugging the operation of the device. Modeling
the associative co-processor was carried out in CAD Web pack ISE of
Xilinx company. This allows to evaluate the correct operation of the
hardware coprocessor in the composition of computing systems without
building the actual layout. Introduction efficiency of the module is
assured by the fact that the coprocessor performs a time-consuming
operation to search for and compare data and thus relieves the CPU and
increases the performance of the computing system as a whole. The
results obtained in the article can find application in the search
engines for different purposes: servers, databases, search machines used
at stations, airports and for fast implementation of the search task
operating systems. |

Claudia Lorena Garzon-Castro, Luis M.
Beltran, Lina K. Corredor and Luis E. Uribe |
Abstract: |
Manage a soccer tournament can be a tedious task if it is done manually.
This article presents the development of SIDUTSA, an on-line system
based on decision trees, which allows the administration of the football
tournaments to be automatic. By entering only, the participating teams
and the results of the matches, the system organizes the matches
automatically at each stage of the championship playoffs, quarter
finals, semi finals and the final. SIDUTSA was developed using the
language of Transact-SQL programming and a SQL Server database manager.
It is shown that it is possible to implement low-cost systems using
efficient software architectures, easy to manage and potentially
scalable. It was possible to develop software that allows you to: 1)
automate the information corresponding to the management of soccer
tournaments, 2) generate reports of the classification of the
participating teams, 3) give independence to personnel in charge of the
logistics, and 4) contributes to the decline in the use of paper. It is
hoped that this tool can be used in other institutions that also carry
out soccer tournaments. |
