In addition, it would address the issues such as Emergency Lanes Misuse, Deaths in Ambulance due to traffic related delays.Road accidents is the 8th leading cause of human death per annum. Day to day observations indicate, Indians in particular follow traffic rules not because of safety but out of fear of being penalized. E.g. people avoid red light jumping if they see a cop stationed right next to traffic signal.“NO HUMAN VEHICLE TOLL SYSTEM” prototype utilizes Radio Frequency Identification (RFID) Technology and camera projections. It detects the RFID tags via radio waves pre-installed in vehicles. RFID readers installed on the roads would read RFID tags using radio waves, the moment a vehicle passes through it. The signal would then be send to the microcontroller for further processing. Arduino Mega microcontroller is utilized in the prototype. The microcontroller connected to internet commands the server to search for unique RFID tag in the database and advances the process per protocol. To make the system more robust, AI cameras are being utilized to take pictures of the registration plates for reconfirmation before ticket issuance.Based on the above, the prototype would potentially address issues such – Traffic Signal Jumping, Over speeding, Intentional hindrance of Emergency Vehicles, tracking lost vehicle(s), Fake Registration Plate Detection, Driving without Seatbelt and Helmet, Drinking and Driving .In terms of numbers, it may result in 80% reduction in road accidents.","PeriodicalId":143710,"journal":{"name":"European Journal of Engineering Science and Technology","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123657646","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}

It is one of the most significant aspects of water resources management and development programme to use different hydrological models for predicting the flow of river basins. Calibration and validation of the developed hydrological model is also important so that the model users can be confident while estimating the flow of the watershed. In this study, a semi-distributed hydrological model was developed for 0.176 million km2 Upper Blue Nile river basin using Soil and Water Assessment Tool (SWAT). The applicability of SWAT was assessed for rainfall- runoff simulation in Upper Blue Nile basin. The model was calibrated and validated using 10 years of discharge data. Model calibration and sensitivity analysis were performed with sequential uncertainty fitting (SUFI-2), which is one of the programs interfaced with SWAT, in the package SWAT-CUP. The most and least sensitive parameters were CN2 (curve number) and GW_DELAY (ground water delay time) respectively. Performance of the model was evaluated based on Nash Sutcliff Efficiency (NSE) and Coefficient of Determination (R2) which were 0.71 and 0.66 respectively for calibration. Overall, the model demonstrated good performance in producing the patterns and trend of the observed discharge which assures the suitability of the SWAT model for future scenario analysis. Uncertainty analysis of the SWAT model of upper Blue Nile basin, consideration of other parameters and incorporating more flow data from other stations within the basin is recommended for future studies.","PeriodicalId":143710,"journal":{"name":"European Journal of Engineering Science and Technology","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121936280","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}

The samples, having three different fiber orientation angles as ± (40°), ± (55°) and ± (70°), were fabricated by filament winding technique. Crushing parameters, in terms of load-displacement response, load carrying capacity, energy absorption capability and mean crushing stress, were determined for each sample. The results showed that the fiber orientation angle were found to have significant influences on crashworthiness of composite pipes. The increase in fiber orientation angle resulted with decrease in energy absorption capability and increase in crushing load efficiency. In the view of specific energy absorption aspect, minimum value of 32.20 J/g was obtained in ± (70°) fiber orientation and improvements up to 46% were achieved by increasing in orientation angle. Also, detailed investigations on fracture mechanisms were performed to understand failure modes. All samples were exhibited the progressive crushing in types of lamina bending or brittle fracturing.","PeriodicalId":143710,"journal":{"name":"European Journal of Engineering Science and Technology","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129477732","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}

Owing to containing high fluxing agent, green glass cullet had been selected to develop wall tiles. It can reduce the sintering temperature of ceramic bodies. In addition, the green color of waste glass can promote the new texture of ceramic wall tiles. All materials used in this study consisted of green glass cullet (GGC), local ball clay (LBC), and local white clay (LWC). They were dried, milled, and sieved through a 50 mesh (297 micrometers) screen. Mixture formulations of materials had been conducted by using a tri-axial diagram. The rectangular specimens with dimension 50x100x7 mm were prepared by uniaxial pressing. They were all fired at 950oC with soaking for 1 h. Bending strength and water absorption of specimens were tested and compared with a Thai Industrial Standard (TIS 2508-2555). The results revealed that the formula contained 60% GGC, 30% LBC, and 10% LWC can achieve TIS 2508-2555. In addition, Scanning Electron Microscopy and X-Ray Diffraction technique were employed to characterize the microstructure of specimens.

In other words, it is necessary to define a subtle and nuanced set of complementary possibilities between human beings and nature while investigating metropolitan landscape structures. To this end, this paper aims to elaborate on the natural structures of the river-valleys of Tehran with specific consideration of one river-valley called Darband. With a length of 33km through the urban and peri-urban areas of Tehran from the northernmost to the southernmost points, Darband river-valley provides a wide range of potentials – as well as problems – in terms of human-nature interaction in its neighborhoods. This spectrum of potential includes mainly: inner-city local and medium-sized parks and the tendency for neighborhood-scale communication; urban spaces of squares and streets and the disappearing history; big parks and unconstructed pieces of land and social attitudes associated with specific days; mountainous recreational areas; and bridges as landscape in transit as well as acting as pause points. In this design- and context-based research, the applied methodology consists of a review of the related literature, direct observation, interviews, and design and planning. In this paper, the focus is primarily on socio-cultural aspects of sustainability, and the environmental aspect is studied as an affiliated and interdependent aspect.","PeriodicalId":143710,"journal":{"name":"European Journal of Engineering Science and Technology","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126273093","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}

The fiscal area represents a strategic sector for the public administration and the recent introduction of the electronic tax process by the Italian Ministry of Economy and Finance has made it possible to significantly improve the resolution of tax disputes. With the aim of overcoming some of its data security limits, in this work we propose a blockchain based solution designed to improve the conduct of the digital tax process by making it safer, faster and with lower transaction costs. In particular, the main improvements relate to two different dimensions of analysis, on the one hand a better level of privacy guaranteed by the introduction of trial files within a blockchain network, on the other hand the use of smart contracts ensures the enforceability of the court's decision and reduces transaction costs related to the conduct of the tax process. The specific model designed is based on a permissioned blockchain and an algorithm for reaching distributed consent, for which we describe in detail the principles of operation that allow the different entities involved to take part in the tax process.","PeriodicalId":143710,"journal":{"name":"European Journal of Engineering Science and Technology","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-08-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133150889","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}
