Geopolymer was widely used for development purposes, but only a few were tested for machining purposes. This study focused on the parameter which can give effect to the tool wear in structural rubberized fly ash geopolymer (RFGP) and the most significant factor of machining in giving the best tool wear. This experiment was conducted using a CNC lathe machine with cutting speed 1000, 2000 and 3000 rpm, feed rate 0.05, 0.10 and 0.15 mm/rev and depth of cut 0.2, 0.4 and 0.6 mm. Taguchi L9 orthogonal array was used to design of experiment. Optimal cutting conditions was determined using signal-to-noise (S/N) ratio which calculated for VB max according to the “smaller-is-better” approach. The effects of the cutting parameters on tool wear were evaluated by analysis of variance (ANOVA). Results implied tool wear decreased with cutting speed. Therefore, the cutting speed of 2000 rpm, feed rate 0.15 mm/rev and depth of cut 0.4 mm demonstrated the lowest tool wear. The statistical analysis showed that the parameters that have the biggest effect on VB are the cutting speed and feed rate, respectively.Geopolymer was widely used for development purposes, but only a few were tested for machining purposes.

The ‘dadih’ and milk factory is kind of a small factory and it is called as SME (Small and Medium Enterprise). The purpose of visiting to these factories is to find out the main problem faced by the factories currently. Through a series of analysis such as questionnaire, interview and also observation, the problems are found. According to the factories visited, the cooking method by the factories are varies. Some of the factories are using the traditional method which is cooking by using gas stove and some are using semi-automated boiler. However, the boiling point of the traditional cooking method is around 100°C and it is not able to kill the milk spores in the milk products. A high temperature (135°C-150°C) to cook the milk products in short time (3s-5s) is the basic requirement to kill the milk spores in the milk products. The milk spores are the main reason to shorten the life span of the milk products. According to the information provided by the factory, the life span of ‘dadih’ produced by using the traditional method are very short which is maximum 2 or 3 weeks if it is refrigerated. In other words, if the products are placed in a normal room temperature, it will not last more than 4 hours. The problem is those factories are intended to buy a UHT boiler but the existing boiler in the market is too big and too expensive which is not suitable and affordable by Small and Medium size (SME) companies.

The complexity in housing affordability issue requires more consideration beyond mere economic viability. To increase life quality and well-being, the percentage of income spent on rent by individual household is essential for consideration. This study attempts to evaluate low income affordability level in Ado-Ekiti, Ekiti State Nigeria. A structures questionnaire was used to obtain data while analysis was done through Statistical packages for social sciences (SPSS). The outcome of the analysis indicated that a larger percentage of the targeted population spends above 30% of their monthly earnings on housing services. This relate with the benchmark set by several scholars, where authors maintained that a cost burden will exist where households spend above 30% on their housing services. This paper then concludes that majority of the dwellers in the study area experience a cost burden as they spend a large percentage of their monthly income on house rent. Hence this adversely affect their ability to meet other living expenses like medical bills, education, clothing, food and son on. Some recommendations are been suggested to improve the low-income housing affordability standard both within and outside the study area.

Fused deposition modelling (FDM) is a fast growing rapid prototyping (RP) technology due to its ability to build functional parts having a complex geometrical shape in a reasonable time period. The quality of built parts depends on many process variables. In this study, three important process parameters, such as layer thickness, orientation, and infill, are considered. Their influence on two responses such as tensile and flexural strength of test specimen is studied. Experiments are conducted based on the Taguchi method in order to reduce experimental runs. Empirical models relating response and process parameters are developed. The validity of the models is tested using analysis of variance (ANOVA). The major reason for weak strength may be attributed to distortion within or between the layers. Finally, the concept of desirability function is used for maximizing all responses simultaneously. It was found out that the use of layer thickness 0.25 mm, the orientation of 0 degrees, and infill of 100% are suggested in order to find the good strength for three-dimensional printing (3D printing) fused deposition modeling (FDM). Based on the result, it shows that the infill is the most significant factors that affect the strength of the three-dimensional printing (3D printing) fused deposition modeling (FDM) process followed by orientation and the layer thickness.Fused deposition modelling (FDM) is a fast growing rapid prototyping (RP) technology due to its ability to build functional parts having a complex geometrical shape in a reasonable time period.

The major reason for weak strength may be attributed to distortion within or between the layers. Finally, the concept of desirability function is used for maximizing all responses simultaneously. It was found out that the use of layer thickness 0.25 mm, the orientation of 0 degrees, and infill of 100% are suggested in order to find the good strength for three-dimensional printing (3D printing) fused deposition modeling (FDM). Based on the result, it shows that the infill is the most significant factors that affect the strength of the three-dimensional printing (3D printing) fused deposition modeling (FDM) process followed by orientation and the layer thickness.Fused deposition modelling (FDM) is a fast growing rapid prototyping (RP) technology due to its ability to build functional parts having a complex geometrical shape in a reasonable time period. The quality of built parts depends on many process variables. In this study, three important process parameters, such as layer thickness, orientation, and infill, are considered.

This paper introduces the isokinetic measurement in randomly applied on the upper arms spasticity patient. Isokinetic is the stroke patient exercise with assist by the medical robotic technologies to therapeutic, diagnostic and laboratory assessment in constant movement. The fatigue of the spasticity patient is ideally vital to understand to make sure the robotic arms is not over drive during exercise. The repetition exercise may cause of medially fatigue. The model propose can predict early fiber muscle action and effect of a range of pulse durations on muscle fatigue. The Spasticity robotic arms was introduced to maximum in medially fatigue can cause damage of the fiber muscle tissue. Flexor Carpi Ulnaris (FCU), Palmanis Longus (PL), Extensor Digitorum (ED) and Extensor Carpi Radials (ECR) is the important muscle body to analyze. The Spasticity Robot Arms (SRA) was design to assists stroke patient in order to understand the capability of user and to provide high impact rehabilitation exercise. The goal of this research is to propose suitable algorithm in order to control multiple degree of freedom (DOF) to achieve a limited number of pre-defined motor synergies. A set of experiments will be conducted on four number of subjects to verify the Fugl Meyer assessment of the proposed algorithm.This paper introduces the isokinetic measurement in randomly applied on the upper arms spasticity patient.

A copper nanoparticle exhibit electromagnetic spectrum that is potential in a biosensor development. It is crucial to design a low cost nanoparticle biosensor that is easily fabricated at precise sizes and density. This paper provides a convenient method for copper nanoparticle deposition on a glass substrate with a magnetron sputtering process known as Physical Vapor Deposition. The main objective is to determine a reliable prediction recipe for various nanometer copper film thicknesses. In this experiment, six glass slides were coated with copper at different sputtering time. The time was varied from 280 sec to 980 sec while Argon gas and DC power were maintained respectively at 80 sccm and 130 watt. Later, the optics based measurement and electron microscope were employed for assessing the copper film thickness. The experiment result indicates different thicknesses were achieved from 35 nm to 45 nm at various sputtering time. A uniform and continuous coating were achieved as magnified by Scanning Electron Microscope. The result is beneficial for evaluating the anisotropy of the copper coating for a nanoscale microbial detection at different spectral wavelength.A copper nanoparticle exhibit electromagnetic spectrum that is potential in a biosensor development.
