Published: April 2019

Traditionally human interacts with a computer by using keyboard and mouse. Considering person with handicapped from the wrist to the fingertip or amputated wrists or fingertips need alternative way; using voice or hand gesture. This work focuses on the use of hand-gesture image recognition. There are two main issues should be considered; less interactivity in static hand gesture recognition, and less accuracy in dynamic hand gesture recognition. This paper attempts to improve the accuracy of hand-gesture image recognition by experimenting simple deep learning neural network (DLNN). As this work uses a simple DLNN, the relation between the hidden layers is not considered. The number of hidden layers in the proposed architecture of the DLNN for the experiments vary from one to five.With the aims to understand the effect of the number of neurons in the hidden layers, the DLNN is experimented using different numbers of hidden neurons. Six different types of hand gestures are considered. 800 videos on hand gestures taken from Vision for Intelligent Vehicles and Applications (VIVA) portal are used in the experiment. The data is divided into two; one as training data and another part is for testing. The best result is achieved when the DLNN uses two hidden layers with 250 neurons in the first hidden layer, and 100 neurons in the second hidden layer. The average of the achieved accuracy level is 77.56%. Experimental results also show that the more number of hidden layer causes over-fitting (does not make the recognition better). It is also observed that the increase of hidden layer number and hidden neurons only affect the accuracy of recognition of the trained dataset and does not improve the recognition of untrained dataset. This result is because the interrelation among the hidden layer are not considered.

Published: April 2019

There are number of factors which control the rate of process of natural carbonation and make it very slow in cement based material. Studies show that the effect of carbonation is mostly limited to corrosion of steel reinforcement in R.C.C. structures (including cover depth design and service life prediction). Research at global level is focused on developing a cost effective and safe technology for the possibility of carbon dioxide sequestration as per IPCC guide lines, and attempts are being made to apply the accelerated carbonation technology for CO2 sequestration in concrete.  This paper discusses about the detailed study on the uptake quantity of carbon dioxide in concrete, increase of strength and changes in mineral content by adopting. The concrete grades of M15, M20, M25 and M30 were taken for investigating the strength with respect to time of exposure and pressure by adopting Accelerated Carbonation Technology by using commercially available pure CO2 for carbonation curing. After the testing of concrete for strength, XRD analysis was carried out to study the conversion of calcium hydroxide into calcium carbonate due to carbonation.  This green technology would help cement, concrete, precast product and other similar manufacturing industries to obtain carbon credit and they can adopt this green technology to reduce their industrial carbon dioxide emissions into the atmosphere to reduce global warming.

Published: April 2019

An assortment of retrofitting strategies are utilized to redesign existing structures. Fiber Fortified Polymer (FRP) materials have been utilized to reinforce numerous basic segments. One of the promising strategies for reinforcing solid individuals in flexure is the close surface-mounted (NSM) FRP strategy. The greater part of the occasions, holding is the basic factor that controls the structure of this method. In this examination, pullout tests were performed to explore the holding conduct of NSM-CFRP poles. The parameters were the span of the CFRP bars and the notch geometry. The goal of this investigation was to acquire a pullout limit that is in any event half of the CFRP rigidity. Three diverse pole sizes were utilized, and an aggregate of six pullout examples were tried. The outcomes demonstrated that utilizing parallel scores essentially expanded the pullout quality. Without horizontal depressions, the most extreme pullout quality for the littlest bar estimate was under half of the CFRP rigidity. The outcomes additionally demonstrated that the security quality is exceedingly influenced by the distance across of the CFRP bars.
Empirical Formula for Assessment Concrete Compressive Strength by Using Ultrasonic Pulse Velocity
Authors: Shakir Al-Aasm Hameed
Published: April 2019

Statistical practical program was carried out to establish a fairly accurate empirical formula between compressive strength of concrete and ultrasonic pulse velocity. The work has a strong empirical base, but it is firmly governed by theory. In concrete, the compressive strength of concrete is related to the type, proportion and physical properties of aggregate but it is well known to be intensely affected by the properties of the cement paste, which relate, mainly, to the w/c ratio. The other variables such as age and density of concrete, salt content in fine aggregate and curing method have a relatively little effect on compressive strength of concrete. Therefore, the program involves field testing of reinforced concrete members that their w/c ratio and cube uniaxial compressive strength are known. The results were used as input data in statistical program (SPSS) to develop an empirical formula between the compressive strength of concrete and ultrasonic pulse velocity. The proposed formula was confirmed by the results of previous experiments. Although the relationship between the compressive strength of concrete and ultrasonic pulse velocity physically indirect, the statistical program revealed that the pulse velocity test could be used with acceptable error in evaluating the compressive strength of concrete.

Authors: Rodi N.S.Noor , Malek M.A. , Ismail A.R.
Published: April 2019

Nowadays, various algorithms inspired by natural processes have been extensively applied in solving engineering problems. This study proposed Artificial Immune Systems (AIS), a computational approach inspired by the processes of human immune system, as an algorithm to predict future rainfall. This proposed algorithm is another alternative technique as compared to the commonly used Statistical, Stochastic and Artificial Neural Network techniques traditionally use in Hydrology. Rainfall prediction is pertinent in order to solve many hydrological problems. The proposed Clonal Selection Algorithm (CSA) is one of the main algorithms in AIS, which inspired on Clonal selection theory in the immune system of human body that includes selection, hyper mutation, and receptor editing processes. This study proposed algorithm is utilised to predict future monthly rainfall in Peninsular Malaysia. The collected data includes rainfall and other four (4) meteorological parameters from year 1988 to 2017 at four selected meteorological stations. The parameters used in this analysis are humidity, wind speed, temperature and pressure at monthly interval.  Four (4) meteorological stations involved are Chuping (north), Subang Jaya(west), Senai (south) and Kota Bharu (west) represented peninsular Malaysia. Based on the results at testing stage, it is found that the trend and peaks of the hydrographs from generated data are approximately similar to the actual historical data. The highest similarity percentage obtained is 91%. The high values of similarity percentage obtained between simulated and actual rainfall data in this study, reinforced the hypothesis that CSA is suitable to be used for prediction of continuous time series data such as monthly rainfall data which highly variable in nature.  As a conclusion, the results showed that the proposed Clonal Selection Algorithm is acceptable and stable at all stations.

Miniature microstrip diplexer at band frequencies of (1.45/1.95GHz and 2.5/3.5GHz) in two considered channels using the coupled stepped impedance resonators (SIRs) has been presented in this study with mathematical analysis. This diplexer has dual pairs of coupled SIRs with impedance ratio and the source-load coupling lines. As a result of the tuning of impedance ratio and length ratio  of SIRs, the resonant modes are possibly determined to achieve 2nd order bandpass filter (BPF) with dualband frequency responses for the investigated diplexer. The investigated microstrip diplexer has a simple outline, compact dimensions, an in effect design technique and straightforward calculations of impedance, electrical lengths, fractional bandwidth, coupling factors and other electrical specifications.

Book is an important medium for teaching in higher education. It is facilitated by a library or a reading room which enabled student and teacher to fulfill their references for teaching and learning activities. For easy searching, each book classified by categories. In our institution, Information Technology Major of State Polytechnic of Malang, those categories are specifics to computer science topics. Every book entry need to be classified accordingly and to perform such task, one need to understand major keywords of the book title to correctly classify the books. The problem is, not all the librarian have such knowledge. Therefore manually classifying hundreds and even thousands of book is an exhausting work. This research is focused on automatic book classification based on its title using Naive Bayes Classifier and Log Probabilistic. The Log Probabilistic implementation is to solve the probability calculation result that is too small that cannot be represented in a computer programming floating points variable type. The algorithm then implemented in a web application using PHP and MySQL database. Evaluation has been done using Holdout method for 240 training dataset and 80 testing dataset resulting in 75% of accuration. We also tested the accuracy using K-fold Cross Validation resulting in 66.25% of accuration.

This paper describes the use of virtualization technology in the linux network teaching process in linux firewall implementation. The problem that is often faced by teacher and student is the limitation of computer devices in implementing network topology design. The use of virtualization technology can be used as a device to create a virtual network laboratory, which is an implementation of real laboratories and network simulation software that is useful to explain the concept of computer network management. With this in mind, it can provide an overview of project characteristics, especially the implementation of linux networks in the area of virtualization technology. Linux network virtualization implementation to help the teaching process used netkit. Netkit can be used as a linux network simulation, where each virtual machine host has a linux operating system, and can implement a computer network based on the design of a real network topology. The method used to implement the Linux firewall by creating a virtual laboratory, where virtual laboratories are built based on the real network topology design. Testing is done on a virtual laboratory by implementing a network topology design and running based on a test scenario.

This experiment investigates the effects of utilizing Rahnama cultivar with high non-starchy polysaccharide content and supplementation of xylanase enzyme in poultry feed on the productivity features, nutrient digestibility and intestinal enzymes activity of 21-47 week laying hens. The experiment was conducted quite randomly and in factorial design that included eight treatments with 4 wheat levels (zero, 23, 46 and 69% that contained 1.8, 2.0, 2.2, 2.4% of xylose respectively) and two level enzymes (with and without enzyme) and 5 replications (6 hens) in each replication. During the experiment, by xylose level increase in diet, the weight (p>0.05) and mass of the egg (p>0.01) decreased and feed conversion ratio increased (p>0.05) but there was no effect on feed consumption and egg production rate. Diet supplementation with xylanase resulted in egg production increase (p>0.05), weight and mass increase of eggs (p>0.01) and improved feed conversion ratio (p>0.01). Xylose levels increase resulted in decrease in fat and metabolic energy digestibility of the diet (p>0.05); and, amylase enzymes activity in duodenum and amino peptidase, and lipase in duodenum and jejunum (p>0.01) increased. However, xylanase supplement had no effect on any intestinal enzymes. Diet supplementation with xylanase decreased viscosity of ileum (p>0.01). Increased xylanase level in diet resulted in decreased productivity features of laying hens, increased intestinal enzyme activity and decreased fat and metabolic energy digestibility.
