Application of Storm Erosion Index (SEI) to parameterize spatial storm intensity and impacts from Hurricane Michael
Authors: Janssen Matthew , Lemke Laura , Miller Jon
Published: December 2019

Hurricane Michael made landfall as a Category 5 Hurricane on 10 October 2018 between Mexico Beach, Florida and Tyndall Air Force Base in Panama City Beach, Florida causing damages totaling $25 billion (Beven et al. 2019). While damages were caused by both wind and surge, this paper is solely concerned with the surge induced damages which were observed predominantly within 50 km (27 nmi) of the hurricane’s path. Generally, regions to the east of Hurricane Michael’s landfall sustained the most severe damages and appear consistent with the spatial gradient in peak water levels. This gradient was marked; with surge induced damage concentrated in the immediate vicinity of Mexico Beach and attenuating significantly over distances as little as 37 km (20 nmi) to the west in Panama City Beach and east in Port Saint Joe (Kennedy, in review). The gradient in erosion was also pronounced, with Panama City Beach experiencing an average erosion rate of 0.4 m3/m (3.9 cy/ft) while Mexico Beach and Cape San Blas experienced rates approximately three (1.1 m3/m or 11.5 cy/ft) and five (1.7 m3/m or 18.5 cy/ft) times that. For inherent reasons, the pronounced gradient in surge damages and erosion values are of primary interest to coastal researchers and managers. Storm Erosion Index (SEI), developed by Miller and Livermont (2008) combines the three primary drivers of coastal erosion (wave height, total water level, and storm duration) into a physically meaningful form to evaluate storms based on their erosion potential. Here, SEI is applied to explore these spatial variations at seven distinct regions within the Florida Panhandle and are compared to the observed impacts for both erosion and structural damages. These regions include: (west to east) Panama City Beach, Tyndall Air Force Base (AFB), Mexico Beach, Cape San Blas, Port St. Joe, St. Vincent Island, and St. George Island. Empirically, the cumulative SEI relates well with the observed beach erosion; while the Peak Erosion Intensity (PEI) was found to better capture the trends in structural damages. By capturing the spatial variation of the storm intensity, SEI and PEI are therefore proposed as a viable engineering demand parameter with potential applications in community scale fragility curves.

Deregulation in power industry is restructuring of the rules and economic incentives that government set up to control and drive the electrical power industry. Restructuring in electricity industry will create new business opportunities where new firms selling new products and services will appear, consumers will have alternatives in buying electricity services, and new technologies such as metering and telecommunication devices will develop. Bidding by participants is one of the major challenges. To overcome this issue, strategic bidding models are being developed based on market structure, auction rules and bidding protocols. This paper proposes to formulate an optimal bidding strategy algorithm for DisCos and analyze its impact in the market operations. The bidding optimization is aimed at developing bids that get selected in the market operations and simultaneously maximizing the total profit of DisCos and minimizing power imbalances. Power Exchange market, which is simple yet enables competition, will be considered. This is proposed to be done using MATLAB coding and Genetic Algorithm tool box. Multiple simple bids are modeled. Power imbalance for each of the possible cases is computed. Decision variables (L1,L2,L3) and (C1,C2,C3) are used in order to compute objective functions i.e. Minimization of Power imbalances and maximization of profit, using MATLAB coding and GA tool box.

Conventional trolley needs to be pushed physically around the building. When more items are placed in the trolley, the trolley becomes heavier and harder to navigate. In order to solve this problem, this paper proposes a modification made to the conventional trolley and discusses the viability of using color as the automatic following mechanism on the shopping cart. Two tests are conducted to investigate the performance of the intelligent shopping cart. The first test is to find the most suitable color whereas the second test is to evaluate the reliability of color to be used as the following mechanism. The assessment of results utilized Euclidean distance equation and Matlab/Simulink. The results shows that the Red Green Blue (RGB) pixel value of the chosen colors are changing as the trolley moves around the building because of the lighting position and intensity around the building. The color detection apps is able to endure a limit of 18.03% of color difference from the original selected color before it loses the reference. The utilization of only color as following mechanism has a high tendency to be disrupted by noise because of an adjustment in light intensity and lighting position.

This paper presents an experimental investigation of shear and flexural bond strength of masonry prisms for newly developed sediment masonry bricks. The masonry prisms were constructed in three levels stack-bonded prisms for shear bond strength test and five levels stack-bonded prisms for flexural bond strength test using cement mortar and cement-lime mortar with pre-wetted and dry masonry units. The bond strengths of sediment brick masonry were tested accordance with RILEM TC 127-MS and ASTM E518 for shear and flexural bond strengths respectively. The results were compared to clay brick and cement-sand brick masonry. The results show that pre-wetted sediment brick masonry exhibits higher flexural and shear bond strengths of about 1.5 times and 5 times respectively compared to dry (non-wetted) sediment brick masonry. Using cement-lime mortar in pre-wetted sediment brick masonry leads to increment of the bond strengths and pre-wetting action is essential for sediment brick masonry to prevent failure of shear bond strength.

Due to rapid expansion in road transportation, a more environmentally benign fuel is required in order to control the air pollution. More competent and feasible development of the transportation sector has attracted many interests from various countries including Malaysia. Ethanol fuel is cleaner and sustainable compared to gasoline fuel. Although first generation bioethanol has been utilized globally, it raised the concern about food versus fuel issues. The solution for this is by utilizing agricultural waste as feedstock for bioethanol production. Therefore, this paper investigated the rice straw bioethanol production and its effect on economy and environment when rice straw bioethanol is utilized as a gasoline substitute in Malaysia. Approximately 6% of total gasoline consumption could be saved if rice straw is utilized for bioethanol production, while reducing 92% of air pollution. Based on the life cycle cost model, it was found that the total production cost for 50 ML rice straw bioethanol production plant with a lifetime of 20 years amounts to nearly 200 million USD, which the unit production cost is 0.16 USD per liter of bioethanol, which is Lower than the gasoline price. Therefore, Malaysia should consider bioethanol as a potential alternative fuel to address the problem of depleting fossil sources and global warming.

The use of roller compacted concrete pavement (RCCP) has increased noticeably over the last few decades, given its economic and environmental benefits. This type of concrete is known for its ability to incorporate natural wastes, such as fly ash. Moreover, to improve the performance and enhance the workability of RCCP, superplasticizer can be used. This study aims to investigate the effect of superplasticizer on the performance of high volume fly ash (HVFA) in RCCP. In achieving this aim, different mixtures of RCCP were prepared, where fly ash replaced 50% of the cement content, in addition to adding superplasticizer in quantities equal to 0%, 0.25%, 0.50%, and 0.75% by weight of the cementitious content. The results showed that up to 0.75% superplasticizer content that there was first, a positive relationship between the superplasticizer content and the compressive, splitting-tensile, and flexural strength. Secondly, increasing the superplasticizer content from 0% to 0.75% caused a noticeable improvement in the workability of the HVFA RCCP and caused a decrease in Vebe time of around 12 s. lastly, superplasticizer caused a reduction in porosity of HVFA RCCP and increased water absorption. Accordingly, this study revealed that it is possible to produce workable and durable concrete with high strength by adding superplasticizer to HVFA RCCP.

Thermoelectric generator can utilize various combinations of heat sink and heat source. In this paper, the performance of thermoelectric generator that uses surrounding air as heat source and coldness from ice-water mixture is presented. The objective was to evaluate the open circuit voltage produced by thermoelectric generator, at a range of differences in temperature between the cold and hot surfaces of module. In this work, the thermoelectric module was placed between aluminum heat sink and cold beverage container that contained ice-water mixture. The heat sink operates using the difference in buoyancy of surrounding air (i.e. natural convection). The hot and cold surfaces temperature of thermoelectric modules was measured using Type-K thermocouples. A digital multimeter was connected to the thermoelectric module for measurement of open circuit voltage. The open circuit voltage produced by the thermoelectric generator was linearly proportional to the magnitude of difference in temperature of two surfaces of a thermoelectric module. The electrical power produced by the generator was up to 14 miliWatt. A simple test showed that with a suitable voltage amplification device, this thermoelectric generator can supply enough power for LED bulbs. The finding presented is suitable for the development of energy scavenging devices, which is relevant to stand-alone power generation system.

This paper presents a study on the voltage and electric fields behaviours of a 10kV polymer insulator with moss deposited under dry (air) condition. The aim of this study is considering on the electrical behaviour of insulator by having a surface layer of moss on it that can change the withstand voltage of insulators. It should be mentioned that these moss layers are commonly crated in the jungles especially in the tropical countries. To study on the above mentioned case, simulations were carried out using ANSYS High Frequency Structure Simulator (HFSS). The simulation insulator modelling includes the computerized evaluation of voltage and electric field distribution at three different locations for both clean and moss contaminated insulators. Noted that the electric field and also voltage profiles at different parts of insulators has been determined using applied simulated model. The moss contamination polymer insulator displayed a discontinuous distribution of the electric field compared to the clean insulator and their voltage distribution decreased with distances from the source. The results indicated that electric field along the insulator surface were greatly affected by hydrophobicity characteristic of the polymer. Therefore, the surrounding air of the moss contaminated insulator was prone to initiate a flashover.

This paper proposed a programmable wireless router testbed designed using a microcontroller, Raspberry Pi. The proposed router provides a solution to the limitation of off-the-shelf wireless router on its ability to be configured and embedded with new algorithms. The proposed router testbed is designed to have one Header Pi and three Forwarding Pis which act to inject label and forward packet respectively. The evaluation of results is validated with off-the-shelf router. From the setup, it is proven that Raspberry Pi is suitable to be used as a testbed for academic experiment as it has the ability to be reprogrammed. In addition, it has a compact design which eases for laboratories use. Based on the performance evaluation results, both proposed Raspberry Pi router testbed and off-the-shelf router are in line with each other despite the expected differences in terms of throughput, delay and jitter performance. This proves that the designed programmable Raspberry Pi router testbed can be utilized for small-scale hardware experiment purposes rather than software simulation.

Diabetes has shown to be a chronic disease world over, mainly caused due to reduced physical activity and increased obesity. World health organization statistics show diabetes as a leading cause of disability universally. To avoid extreme medical conditions of subjects, regular monitoring of their glucose levels has been suggested. The most common method that has been in use is the pinprick method for glucose monitoring which carries the risk of contamination as well as irritation. One possible approach called noninvasive technique can be adopted to avoid this major concern. This paper presents designing Inter-Digital-Sensor (IDS) for non-invasive sensing of the glucose level. The sensor-based chip once mounted onto the upper arm or pinkie finger of diabetes subject, is able to sense different glucose levels concentration as impedance plots. A set of several simulation results has been obtained using COMSOL for getting optimized dimensions of the sensor digits. This research has presented the generation of an electric field and intensity by using electrode of known length with element spacing varying from 250μm to 600μm developed over 15mm x 20mm sensor area. An ID of 475μm width spacing with ten (10) digits producing 2.33 pF of capacitance value with impedance resonating at 13 GHz of frequency is reported in this paper.

Composites are not isotropic like their metal counterparts, e.g. steel and aluminum, as they are made of two distinctive phases known as the matrix and the reinforcing phases. In addition, weight, fiber direction, fiber composition and even the manufacturing process are all critical factors in determining the strength, stiffness and the behaviour of a composite member. All of that create more challenging designing and manufacturing approaches. This paper shows how to model a GFRP cross arm using SOLIDWORKS to create the 3D geometrical model because it has an intuitive and easy to use user interface, and ANSYS to create the numerical model and the analysis for its great and comprehensive capabilities in the finite element analysis. The cross arm was found to be safe against the failure modes of fiber, matrix, in-plane shear, out-of-plane shear and delamination under all load cases which satisfies the ultimate limit state requirements but the concern was on the serviceability limit state which had a deflection of 34 mm.

The present work investigates the wear properties of nanoclay-modified carbon fiber reinforced polymer (CFRP) composites when sliding under adhesive and abrasive wear. The specimens were fabricated using epoxy resin, short carbon fiber, and nanoclay filler of 1.0wt%, 3.0wt%, and 5.0wt% content. The wear tests were conducted using pin-on-disc and abrasion resistance test rig for adhesive and abrasive wear condition, respectively. Operating parameters were fixed at 30N load, 300rpm speed and 10km distance for both tests. Pure CFRP composite exhibited lower wear performance compared to pure epoxy in both test conditions. However, with nanoclay incorporation, the wear properties of CFRP composite have improved up to 56% and 44% under adhesive and abrasive wear, respectively. Therefore, the composite reinforced polymer of carbon fiber and nanoclay filler in epoxy matrix provides a synergistic effect under adhesive and abrasive wear conditions. The experimental findings suggest that the CFRP composite has the potential for tribological components and application such as sliding-contact and rolling-contact bearings.
