The secondary congestion problem arises from the pooling of the trucks at the port gates because of the delays of the port operations. The absence of the truck parking areas inside the port causes additional truck trips between the port and auxiliary truck servicing areas around the port. For reducing the impacts of the associated problems of the port induced truck traffic, truck parking areas can be used as buffer zones between the port and city. The purpose of this study is to develop a Decision Support System (DSS) with using multimethod simulation and cost optimization model for the capacity design of a truck parking area for a city port. The preliminary design of the parking area is used to estimate the development cost and outputs of the simulation model is coupled for the capacity optimization for truck arrival scenarios. The methodology is implemented for a case study of the İzmir city port in Turkey. The results of the study indicated that significantly different parking area capacities are required for different truck dwell times for the time restricted and unrestricted truck arrivals","PeriodicalId":7140,"journal":{"name":"Acta Scientiarum-technology","volume":"58 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2022-07-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80512033","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The fibers used in this study are made of Polyethylene Terephthalate (PET), produced from soft drink bottles, and added to the soil with 2 mm width and 1 cm length, in the content of 1% in relation to soil dry mass. Also, contents of 3% and 5% Portland cement, in relation to soil dry mass and two additives, additive 1 at a ratio of 0.25 kg m-³ dry soil and additive 2 at a ratio of 0.60 kg m-³ dry soil, were used to evaluate the possible effect of these variables on the investigated engineering behavior parameters. The compaction results indicated that the inclusion of PET fibers in soil-cement mixtures tends to decrease the maximum dry unit weight compared to fiber-free mixtures. Also, if compared to soil-cement-fiber mixtures, the incorporation of additives to soil-cement-fiber composites resulted in higher values of maximum dry unit weight and lower values of optimum moisture content, but still maintaining values lower than obtained for compacted soil. Results of the direct shear test showed enhanced shear strength with the addition of fibers to soil-cement, for both the parameter of cohesion and the internal friction angle of the material in comparison to fiber-free composites, which demonstrates the potential application of these composites in geotechnical works.","PeriodicalId":7140,"journal":{"name":"Acta Scientiarum-technology","volume":"66 ","pages":""},"PeriodicalIF":0.8,"publicationDate":"2022-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72540224","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this study was to evaluate the influence of a biostimulant and the plant extract (Cyperus rotundus) on the growth forage, and grain production in millet (cultivar IPA BULK 1BF) submitted to salt stress conditions. The research was carried out at the Serra Talhada Academic Unit, Federal Rural University of Pernambuco, in the Semiarid region of the Northeast of Brazil, from February to April 2017. The experiment was installed in randomized blocks, in a 3x4 factorial scheme, composed of a biostimulant (ACADIAN®), nutsedge extract, and the control, in four salinity levels of the irrigation water, electrical conductivities of 0, 1, 2 and 4 dS m-1, with four repetitions. Biometric analysis of all plants was carried out weekly to monitor crop growth. At 77 days after emergence, measures of net CO2 assimilation and transpiration rates were obtained. The harvest occurred with the maturation of the grains (ED9), being analyzed the dry mass of the different morphological components of the plant. The biostimulant at the level of 2 dS m-1 promoted an increase of 66% in the leaf area of millet compared to the control. With 4 dS m-1, the nutsedge extract provided an increase of 253% in the leaf area compared to the control. These expressive results obtained with the use of these compounds reflected in a production of dry leaf blade mass. The IPA BULK 1 BF millet cultivar has tolerance to the salinity levels studied in this research. The nutsedge extract and the biostimulant are alternatives capable of stimulating the growth and the production of forage of millet under the presence of salts in the irrigation water, however, these compounds have no influence on grain production","PeriodicalId":7140,"journal":{"name":"Acta Scientiarum-technology","volume":"1 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2022-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75220702","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The current study describes the production kinetics of cellulases in stirred tank reactor by using mutant and wild strains of T. dupontii. The fermentation span of both the strains in bioreactor was examined. It is was found in mutant strain of T. dupontii fermentation time required for optimum production was reduced to 48h as compared to 72h in wild strain. The kinetic studies also exhibited greater value of µ (h-1) in case of mutated strain in comparison with wild strain. The effects of some other critical factors like agitation intensity dissolve oxygen, aeration, temperature, size of inoculum and pH was estimated on enzyme production kinetics. The results shows maximum activity of cellulases was attained at 220 rpm, 15% dissolve oxygen, aeration rate 1.5 vvm, 55°C, 8 % inoculum size and pH 5.5 for both strains respectively. The higher values of enzyme production kinetics i.e. Yp/x, Qp, Qx and qp in STR in case of mutant strain indicates its superiority over wild strain of T. dupontii. Thus mutant thermophilic T. dupontii might be a potential candidate for industrial applications.","PeriodicalId":7140,"journal":{"name":"Acta Scientiarum-technology","volume":"60 1","pages":""},"PeriodicalIF":0.8,"publicationDate":"2022-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85990290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

But the available information still throws a stiff challenge to users while selecting the needed information. Such an issue can be solved by applying information filtering for locating the required information through a Recommender System. While using a RS, the users find it easy to curate and collect relevant information out of massive databanks. Though various types of RS are currently available, yet the RS developed by Collaborative Filtering techniques has proven to be the most suitable for many problems. Among the various Recommended Systems available, movie recommendation system is the most widely used one. In this system, the recommendations will be made based on the similarities in the characteristics as exhibited by users / items. The movie recommendation system contains a huge list of user objects and item objects. This paper combines Collaborative Filtering Technique with association rules mining for better compatibility and assurance while delivering better recommendations. Hence, in the process, the produced recommendations can be considered as strong recommendations. The hybridization involving both collaborative filtering and association rules mining can provide strong, high-quality recommendations, even when enough data is unavailable.
