Corrugated core sandwich panels are used extensively in the engineering field. To understand the behavior of the corrugated materials and identify their properties, these materials are investigated to establish their behavior pattern. One method to reduce the complexity of modeling corrugated core sheets is through homogenization. In this paper a homogenization method is derived for sandwich panel with an arc-tan corrugation. The reduction of the 3D plate to 2D orthotropic structure is based on Castigliano's second theory. The derived model for the elastic moduli in x1 and x2 directions is utilized to calculate (E1) and (E2), which are two of five properties that characterize any orthotropic corrugated core sheet. Theoretically derived model compares well with other models found in the literature. The same model can be easily extended to find other material constants needed to fully describe corrugated panels.

Liquid sheets have been studied extensively for the past few decades owing to its importance from atomization point of view. Enhanced atomization is always important for effective performance of injection systems in Internal Combustion (IC) engines and rocket propulsion applications. The atomization depends mainly on the thickness of the upstream liquid sheet. The current study is an attempt to review the prominent works done on analysing the breakup of liquid sheets and techniques used till date for quantifying the dynamics of the breakup.

Energy consumption evaluation was performed on buildings, owned by Kuwait's ministry of public housing, before and after modifying the thermo-optical properties of the existing glazing. The investigated building for this study is located in the State of Kuwait and was selected to highlight the effect of glaze coating on the overall energy efficiency using the country geographical conditions. A simulation software, called DesignBuilder, was used to construct and model the selected building and estimate its electricity consumption after applying different types of glazing modifications. This includes employing commercial coatings and films on the original building double-glaze glass in the form of a single layer nanocoating, multi-layer nanocoating, nanoceramic film, and 30% tented film. Furthermore, the parameters of the original and modified glazes, such as Solar heat gain coefficient, light transmission, and solar transmission value, were obtained experimentally then used in DesignBuilder to simulate the building annual energy consumption. The results indicated that, the original building designed had an annual consumption of about 62.2 MWh, while the multi-layer nanocoating case showed a total consumption of 56.3 MWh. Comparing the two cases, the overall energy saving achieved by the multi-layer nanocoating scenario was roughly 9.5%. The present study confirms that using nanocoatings can be beneficial toward reducing building overall energy consumption, and thus can be considered as an economical solution for the State of Kuwait.

A video signal can be expressed as a 3D signal where the rows and columns of pixels represent the first and the second dimension, while the third dimension is the time. The 3D nature of video signals has produced an additional source of data redundancy; that is, the temporal redundancy. Utilizing signal redundancy is the fundamental driving force for steganography techniques. In this paper, the Directional Pixogram is proposed to optimally exploit the redundancy in a video segment. The Directional Pixogram is a 1D vector that starts from a certain initial position and then grows in the direction of the motion vector associated with that initial position. It is expected that this temporal vector will contain highly correlated pixels. Therefore, the Discrete Cosine Transform (DCT) can express this vector within few significant DCT coefficients leaving a large amount of insignificant DCT coefficients. Thus, experimental results have shown that the proposed Directional Pixogram is able to obtain outstanding stego quality while hiding with very high hiding capacities.

Over the past few decades, the concept of sustainable building has become the mainstream among architects, urban designers, and the building industry. The use of appropriate building materials that demonstrate constructive environmental attributes is of prime importance to realize green buildings. In this context, wood, as a renewable building material, exhibits numerous significant ecological characteristics, including low carbon impact, and low embodied energy. In addition, the simplicity of the timber structural systems, along with their sustainability and biocompatibility, makes them more competitive for constructing buildings than other structural systems. Accordingly, the architectural profession witnessed many exciting experiments using wood in tall buildings as well as in the urban context. However, the main objective of this research is to examine the specific natural characteristics of wood, which qualifies it to be an appropriate replacement for fossil-fuel-based products such as steel and concrete. It also intends to discuss some representative architectural projects, which successfully employed wood as their primary structural system. However, this study aims to highlight the significance of wood as a potentially sustainable resource for the future of the building industry.

Past studies have suggested that welding current and voltage are signature variables that have potential information on welding quality and can be used for real-time monitoring while welding. This work explores the interaction between gas metal arc welding parameters such as stick out distance, gas flow rate and transverse speed to the mean and standard deviation of welding voltage and current. SA 516 gr.70 boiler plates with v-grooves were welded using KUKA KR robot and Fronius TPS 5000 power source. Data acquisition system with a sampling rate of 8 kHz was used to acquire current and voltage data during welding. Experimental tests were organized using central composite design. Mean and standard deviation of voltage and current are analyzed using response surface analysis. The measured voltage was confirmed previously to be an effective parameter for detecting porosity using control chart and probability density distribution. Therefore, in this research, the effects and interactions of welding parameters are statistically analyzed. Stick out distance is concluded to be the most effective factor on to the responses being investigated. A change in the gas flow rate can affect the voltage significantly but will not alter the welding current. In addition, mathematical models are developed to forecast mean and normal voltage and current deviations in real-time.

This paper presents a numerical study of axial behavior of circular concrete columns reinforced with Glass Fiber Reinforced Polymer (GFRP) bars and spirals. A nonlinear finite element (FE) model was developed using ABAQUS to predict the compressive behavior of the concentrically loaded columns. Initially, the FE model was verified using an existing experimental paper which investigate the axial capacity of circular concrete columns reinforced with GFRP bars and spirals. The concrete used in the experiment had a compressive strength of 41.9 MPa. Parametric study aiming at evaluating the effect of varying the longitudinal and transverse GFRP reinforcement ratios in the columns was carried out. The results indicated that both the ductility and peak load increase when the reinforcement ratio increases. For spirals, when the diameter increases or the pith decreases, the ductility and capacity increase but with keeping a pitch that allows confinement in the case of changing the spiral diameter.

In this paper, a cost-free Artificial Intelligence-based application for smartphones built to detect vitamin deficiencies in humans using pictures of specific body organs is introduced. Recent vitamin deficiency detection methods require costly laboratory analysis. A wide spectrum of vitamin deficiencies can show one or more visually distinguishable symptoms and indications that appear in multiple locations in the human body. The application provides individuals with the capability to diagnose their possible vitamin deficiencies without the need to provide blood samples through the analysis of photos taken of their eyes, lips, tongue, and nails. The application then suggests a list of nutritional sources to fight the detected deficiency and the expected complications through nutritional micro-correction. The intelligent software was trained to distinguish and differentiate vitamin deficiencies with high confidence from imagery inputs of the selected body parts that are known to show different symptoms in terms of changes in the tissue's structure when the human body suffers a nutritional deficit. The platform also allows medical experts to assist in improving the range of detection and accuracy of the application through the contribution and verification of visual data of their patients allowing for more refined image analysis and feature extraction capabilities with the potential to surpass human's ability to diagnose medical conditions. This application is a useful tool for people to overcome a global problem that affects millions of people worldwide mainly as a result of inadequate nutritional awareness, and it will help healthcare workers in the long term in obtaining more accurate diagnoses.

The main objective of this work is to calculate the harvested voltage and power from piezoelectric stack installed in the quarter and half car models. Both models are subjected to random excitation at different road classes. The mathematical models are built and developed by using MATLAB/Simulink. The obtained results show that harvested voltage and power are increased with the road roughness levels and car velocity. From very smooth to very rough road levels, the harvested power was increased by 434 mW for quarter car model and 537 mW for half car model.
