The effects of curing conditions and polymer — cement ratio on the compressive and flexural strengths of acrylic emulsion polymer-modified concrete reinforced with steel fibre were investigated. Combined dry and wet curing enable to developed both the strengths of cement matrix and acrylic emulsion polymer together. Inclusion of acrylic emulsion polymer at a certain polymer-cement ratio with steel fibre as reinforcement improves the bonds between the cement matrix and steel fibre due to the acrylic emulsion polymer forms in the cement matrix. In addition, acrylic emulsion polymer modification can significantly improve the flexural strength of the normal steel fibre reinforced concrete. Compared with steel fibre reinforced concrete, the compressive strength of the acrylic emulsion polymer-modified concrete reinforced with steel fibre can increase gradually even after 28 days. The mixtures are tested, both in fresh and hardened states and to meet practical and technical requirement of SFRPMC. The results are analyzed using the Taguchi experimental design methodology. The best possible levels of mix proportions are determined for maximization through compressive strength, splitting tensile strength, flexural strength and modulus of elasticity. Analysis of variance (ANOVA) is performed on the measured data and S/N (signal to noise) ratios. A correlation derived from the results of Taguchi experimental design is proposed as a predictive equation for estimation of strength of these composites.","PeriodicalId":6383,"journal":{"name":"2011 Fourth International Conference on Modeling, Simulation and Applied Optimization","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73003376","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this paper: first of all, using Lambert's model, the power received at the receiver via single reflection propagation inside the cabin was modeled. Then, the free space loss which depends on distance and height of transmitter and receiver from ceiling was calculated. Thirdly, in order to estimate the multipath power penalty, from the impulse response model, the delays spread dispersions and mean delays, which are related to reflection patterns and the distance between transmitter and receiver were derived and modeled. Finally, ceiling bounce model was developed to obtain the impulse response and 3dB cut off frequency. After modeling in the passenger aircraft cabin, the results are the minimum power received and the maximum bud-rate that is available to be achieved.","PeriodicalId":6383,"journal":{"name":"2011 Fourth International Conference on Modeling, Simulation and Applied Optimization","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73880705","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These mutations primarily disrupt the reading frame, leading to an absence of functional dystrophin protein. Exon-skipping through the use of antisense oligonucleotides has served as a promising therapeutic approach for DMD, and clinical trials in DMD patients are currently underway. Recently, stable and less-toxic antisense oligonucleotides have been developed with a higher efficacy in mouse and dog models of DMD. Despite these advancements, this therapeutic approach is limited by relatively poor systemic delivery of antisense oligonucleotides to muscle, as well as toxicity effects. This review highlights the challenges for antisense oligonucleotide-based therapeutics for DMD, in particular with methods using exon 51-skipping.","PeriodicalId":6383,"journal":{"name":"2011 Fourth International Conference on Modeling, Simulation and Applied Optimization","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85016492","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Both natural and manufactured beverages may contain a small amount of alcohol (specifically ethanol) as sugar based food is fermentable into alcohol. Therefore, Muslim consumers must be aware that the allowable percentage of alcohol to exist in the food as mentioned by the Shari'ah is only 0.01%. The main inspiration of this work is to develop a low cost yet reliable alcohol percentage detector for non-alcoholics beverages. The optical properties of beverages that respond to the infrared radiation in the optical wavelengths and frequencies range are thoroughly studied. In the proposed model, percentage of ethanol in the beverages is directly determined by using the first derivative of near-infrared (NIR) absorbance spectrum where the range of wavelength used is from 1680 nm to 1700 nm. By making suitable assumptions of the NIR technique, the alcohol detector system was designed, modeled and simulated by using Microsoft Excel and Microsoft Visual Basic. The model of the alcohol detector system was found to be practical for prototype development and hence the product would help the Muslim consumers to indentify whether the beverages they consumed Halal or not.","PeriodicalId":6383,"journal":{"name":"2011 Fourth International Conference on Modeling, Simulation and Applied Optimization","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2011-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79672463","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most of the current broadband operates at high frequency and thus has limited transmission range. Multi-hop relaying technology is seen as an efficient solution that could enhance coverage and improves system capacity. However, overall system performances worsen as the number of hop increases. Providing efficient route selection is one of the key issues to be tackled to improve overall system performance in multi-hop relay network. In this paper, we propose route selection algorithm based on channel condition for WiMAX Mobile multi-hop relay network.
