Simulation of car bumper material using finite element analysis.

Bumper is one of the main parts which are used as protection for passengers from front and rear collision. The aim of this study was to analyze and study the structure and material employed for car bumper in one of the national car manufacturer. In this study, the most important variables like material, structures, shapes and impact conditions are studied for analysis of the bumper beam in order to improve the crashworthiness during collision. The simulation of a bumper is characterized by impact modelling using Abaqus 6.9 according to the speed that is 13.3 m sec-1 (48 km h-1) given in order to analyse the results. This speed is according to regulations of Federal Motor Vehicle Safety Standards, FMVSS 208- Occupant Crash Protection whereby the purpose and scope of this standard specifies requirements to afford impact protection for passengers. In this research, the three types of material were selected that are relevant to be applied to the front bumper beam. The materials consist of Expanded Polypropylene (EPP), Glass Mat Thermoplastics (GMT) and Sheet Molding Compound (SMC). These materials were studied by impact modelling to determine the kinetic energy, potential energy and strain energy. The selected materials are compared to each other to find the best material with highest material strength and structure. Simulation using Finite Element Analysis software, which is ABAQUS was conducted. The results showed that a modified SMC bumper can reduce the impact of collision with higher performance and was suggested to replace GMT and EPP. The duration taken for SMC to deflect the impact was the shortest compared to GMT and EPP The findings also showed that EPP cannot totally absorb the energy and reduce the impact of collision

Copyright @ 2003 IEEEThe use of terminal shunt capacitance has different effects on the displacement factor and distortion factor components of the power factor. These effects are considered for nonlinear loads with ideal supply, and also where the supply impedance exists but is small compared with the load impedance. Optimization of the displacement factor is found to result in reduction of the distortion factor to a minimum value

Rasio Likuiditas, Rasio Solvabilitas Dan Rasio Profitabilitas Terhadap Price To Book Value (PBV) Pada Perusahaan Food And Beverage Tahun 2011-2014

The writer do the research to show the significant impact in accordance with partial as well as simultaneous in the variable of current ratio (CR), Debt to Equity Ratio (DER), and Net Profit Margin (NPM) toward Price to Book Value at the Food and Beverage company, or sub sector of food and drink which registered in the Indonesia stock exchange period 2011-2014. Whose research is quantitative by using purposive sampling technique thoughtful determining sample, and it can be able to obtained of 16 companies from 20 companies. The writer used a secondary data based on ICMD (Indonesia Capital Market Directory) in the Indonesia stock exchange. To show the analysis method in this research, the writer used an analysis descriptive, regression double linear, classic assumption testing consider: normality testing, multicolinearity testing, auto-correlation testing, and heteroskedasity. Beside that, this method also exist the hypotheses testing by using T technique. F testing toward significant level of 0,05 and coefficient determination (R2). The result of the study shows that in the classical assumption test is not found any problem. Partially shows that the negative variable of current ratio (CR) and variable of Debt to Equity Ratio (DER) do not influence the Price To Book Value (PBV). Net Profit Margin variable influences the Price To Book Value (PBV). Simultaneously, shows that Current Ratio (CR), Debt to Equity Ratio (DER), and Net Profit Margin (NPM) influences the Price To Book Value (PBV) obtained 4.722 Fhitung with significant value 0,005. With the result of the determination coefficient Rsquer obtained 0,151 which mean 15,1% variabel Price To Book Value (PBV) can be explained by CR, DER, and NPM variable, the 84,9% residue is explained by actors outside the research

Hydrography, nutrients and plankton abundance in the hot spot of Abu Qir Bay, Alexandria, Egypt

The hydrography, nutrient levels and plankton abundance were investigated monthly for a complete annual cycle in the southwestern part of Abu Qir Bay, the most polluted and biologically productive area on the Egyptian Mediterranean coast. Intense temporal and spatial variability was observed in all measured parameters characteristic of the effects of several effluents discharged into the bay. Based on the present investigation, the southwestern Bay can be divided ecologically and biologically into two parts: one including the near shore strip, which is directly affected by the waste waters, and a second comprising the southwestern part of the coastal strip and the offshore stations, both of which are relatively far away from the land-based effluents.The Bay water was characterized by low transparency (monthly average: 64-280 cm), dissolved oxygen (monthly average 2.0-6.8 mg/l) and surface salinity (monthly average: 24.8-37.9 ppt), the highest limits usually being in the offshore section. Water fertility and plankton production were high in the Bay indicating an occasionally acute degree of eutrophication, particularly nearshore. Great variations occurred in the concentrations of nutrients throughout the year, with monthly averages of 0.8-50.88 mM for ammonia, 0.42-3.28 mM for nitrite, 1.29-17.36 mM for nitrate, 0.32-3.61 mM for reactive phosphate and 1.09-33.34 mM for reactive silicate. Similarly, the abundance of both phytoplankton and zooplankton showed pronounced temporal and spatial variability, whereas the monthly average chlorophyll-a fluctuated between 2.06 and 52.64 mg/l and zooplankton between 31x103 and 248.6x103 ind./m3. However, the absolute values of all parameters indicated remarkably wider ranges of variations.Significant correlation was found between chlorophyll-a and some ecological parameters like temperature, salinity, transparency, dissolved oxygen, nitrite and between zooplankton and temperature, while there was a significant correlation between nutrient concentrations and salinity changes

Analisis Pemasaran Produk Air Kemasan Sesuai Preferensi Konsumen (Studi di PT. Cahaya Bumi Intanpari)

Competition in the food and beverage business is a profitable opportunity for business actors in this time. Ddetermine the characteristics of bottled drinking water consumers, identify the attributes that become the preference for consumers, and identify the marketing strategy is the purposes of this study. The method used is conjoint analysis and marketing mix (4p). Questionnaires and interviews are done for data collection. It is known that most consumers are less than 25 years old, work as employees, and have a monthly income between Rp 2,000,000 – Rp 5,000,000, domiciled outside the city of Solo and have consumed Airmu products between 1-3 times. The stimuli most liked by the respondents are large size straws (7mm), gallon product types, subscription members, sales promotion through event and available in every mall. While the attribute order that is important to respondents is the type of product (31.756%), sales promotion (24.676%), straw size (17.889%), location (14.14%) and price promos (11.538%). The results of calculation of multiple linier regression are partially known only the price variable has a significant effect on consumer decisions. Meanwhile, the Ftable value of 2.74 and Fcount of 3.839 indicates that all independent variables affect the dependent variablesimultaneously
