But natural fibres suffer from lower strength which can be overcome through hybridisation with stronger synthetic fibres like carbon or glass. This work explores the potential reinforcement of fibres from palm leaf stalks for fabricating polymer composites. The fibres were pre-treated with glass fibres to form as fibre mats and hybridised with glass fibres prior to reinforcement. These mats were reinforced in the polyester resin matrix as different layers to form a hybrid composite. Experiments were done by varying the length of fibre, fibre volume and with different treatments using response surface methodology. Tensile strength was measured as response. The tensile strength was spotted maximum in 8% potassium permanganate (KMnO4) treated palm fibres with optimum fibre length 40 mm and volume fraction of 20%. The surface study on these composites through scanning electron microscope (SEM) examination was satisfactory. Hence this specimen combination was best suited and recommended to manufacture components like car bonnets, bumpers, etc.","PeriodicalId":346646,"journal":{"name":"Int. J. Comput. Aided Eng.

The presence of abrasive reinforcing particles and the conventional machining of these materials induces severe tool wear and poor surface finish. Wire-cut electro discharge machining is one of the best unconventional machining process for AMCs and it continues to rise at an accelerated rate. In this work, an attempt has been made to fabricate aluminium (A6061) reinforced zinc oxide particles by stir casting technique and determine the machinability behaviour of the sample. The process parameters regarded are pulse on time, voltage and wire feed rate and the measurable output parameters are metal removal rate and surface roughness. The experiments are carried through Taguchi's L9(33) orthogonal array as per design of experiment procedure.

For instance, your Google home is listening to you and collecting data, your Facebook knows a lot about you; Amazon's Alexa gets to know our everyday wants. This implies that our data is used to spy on us for advertising purposes, hence these siren servers make the overall profit off us. This paper throws light on developing a dApp (decentralised application) that could be used in a voting system. Everything around us is digitising which does not mean we are moving towards a safe and secured scheme, thus the revolutionary Blockchain technology is used to deploy an e-voting system (Giorgino, 2018) and this is done using the Ethereum Blockchain (Wang et al., 2018).","PeriodicalId":346646,"journal":{"name":"Int.

This trend has become a contributing factor towards increasing unemployment rates in South Africa. Consequently, work integrated learning (WIL) has been introduced in the curriculum of South African universities of technology (UoTs) to bridge the gap between theoretical knowledge and real-life industry experience. To learn the contribution of WIL in improving the quality of graduates, it becomes highly imperative to investigate the impact of WIL with focus on specific discipline. Therefore, based on the Kolb's learning model, this paper investigated the impact of WIL on undergraduate ICT students' learning. A quantitative survey instrument was adapted from existing scales and used on a sample of 76 ICT undergraduate students who had recently completed WIL. The results showed that over 90% of the students indicated that WIL significantly enhanced their learning.","PeriodicalId":346646,"journal":{"name":"Int. J. Comput. Aided Eng.

It is an Audrino based platform equipped with pre-calibrated sensors to sense gases like sulphur dioxide (SO2), carbon monoxide (CO), ammonia (NH3), and particulate matter (PM10) in the air. Audrino board with the gas sensors, global system for mobile communications (GSM) and ZigBee module forms the wireless sensor motes used for the field deployment. Wireless sensor network built with ZigBee links can be scaled up using the GSM connectivity to interface with the external world. Air pollution monitoring is performed using a system of sensor nodes with the help of wireless communication via a ZigBee protocol. We proposed a static wireless sensor network to supervise air contamination level, and a multi-hop algorithm is implemented over ZigBee WSN.

Storing of large images require large storage space. To reduce the storage space, compression methods are employed. In this paper, we analyse the effect of lossy image compression on the performance of biometric identification systems. We propose a scheme to evaluate the recognition performance at low bitrates of hand images. The images are compressed using set partitioning in hierarchical trees (SPIHT) encoding. A powerful feature extraction algorithm based on quantising the phase information of the local Fourier transform is used. The nearest neighbour (NN) classifier and the support vector machine (SVM) classifier are employed to classify the feature extraction. The obtained results show at the compression does not significantly affect the performance of recognition operation at low bitrate for unimodal and multimodal systems. Thus, the low bitrate images perform equivalent to uncompressed images in the recognition system.","PeriodicalId":346646,"journal":{"name":"Int. J. Comput. Aided Eng.

Multiple algorithms and approaches have been developed in order to harvest information from this data. These algorithms have different approaches and therefore result in varied outputs in terms of performance and interpretation. Due to their functionality, different algorithms perform differently on different datasets. In order to compare the effectiveness of these algorithms, they are run on different datasets under a given set of fixed restrictions (e.g., hardware platform, etc.). This paper is an in-depth analysis of different algorithms based on trivial classifier algorithm, kNN, and the newly developed ARSkNN.
