Since the low-precision of m-level navigation application based on GNSS pseudo-range observations, it is insatiable to develop requirements of intelligent command for the construction tower crane. To improve the monitoring accuracy for construction tower crane based on GNSS method, a high-precision monitoring approach applied to fixed-point and lofting of hoisting operation by GNSS carrier phase observations is proposed. It is applied to the intelligent command of hoisting operation for the construction tower crane, and a set of GNSS-based fixed-point and lofting of hoisting operation system, named as GNSS_PLS, is designed and developed. The experimental results show that, for 6 minutes (360 epochs) of the monitor station installed on the top of the construction tower crane, the minimum error of North-RMS is 0.009m, the maximum error of North-RMS is 0.015m and the average error of North-RMS is 0.013m; the minimum error of East-RMS is 0.008m, the maximum error of East-RMS is 0.014m and the average value of East-RMS is 0.011m; the minimum error of Up-RMS is 0.021m, the maximum error of Up-RMS is 0.036m and the average value of Up-RMS is 0.030m. The monitoring accuracy of intelligent command of the GNSS_PLS system is obtained to cm-level and the effectiveness and feasibility of the proposed solutions are verified.","PeriodicalId":14142,"journal":{"name":"International journal of engineering and technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89168869","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}

This research is aimed at improving the method of recognizing inner emotions. The proposed new method is an automated method for classifying emotions using signals (EDA). Temporal analysis of the acquired frequency that provides a space of characteristics, based on which different emotions can be identified. For this purpose, the complex wavelet function (C-Morlet) is applied to the recorded EDA signals. The data set used in this study is a set of multifaceted recordings of social and communication behaviors as well as EDA records. The data set is interpreted to extract a time sequence corresponding to the three main emotions “happiness”, “boredom” and “acceptance”. The simulation results show that the level 3 violet sym4 conversion removes noise from the ETG signal well and increases the signal to noise. The results of the simulation using this method are more efficient than other methods and reduce more noise.","PeriodicalId":14142,"journal":{"name":"International journal of engineering and technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88861207","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 it will be described the application of wireless sensors and Android based application as mobile monitoring tool in achieving highly efficient shrimp aquaculture monitoring system. A set of four water quality parameter sensors (pH, temperature, conductivity and DO) were submerged into the pond using a buoy, in which an electronics and Xbee wireless transmitter have been installed to transmit the measured data into a fixed monitoring station. The main component of the fixed monitoring station was a smart data logger capable of performing automatic aeration system. Data transmission from the monitoring station to the master station was done through GSM/GPRS module of a Raspberry microcontroller. Using internet connection, a web based server has been developed from which the Android based application retrieved the measured parameter data. Graphical analysis of water quality data can be performed from a mobile phone, allowing users to monitor the aquaculture regardless of their geographical location. This system has been implemented in a shrimp aquaculture in Bangka island, Indonesia. In addition to giving real-time water quality data, the system was able to reduce the operational electricity cost because of the automatic aeration feature. Consistently, the system has been sending the measurement data to the web server, which is accessible using Android mobile phones worldwide.","PeriodicalId":14142,"journal":{"name":"International journal of engineering and technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86159739","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}

Perhaps it is due to this point of view which considersarchitecture of each part of the world as an identity for that part. In the modern era especially in the field of ideas’ interaction, the process of globalization needs to apply some elements in biological society which play adominant role in people’s beliefs, and what will be more desirable than architectural signs in environment which are directly judged by all people. The architecture of mosques is regarded as the most prominent proof of architecture derivedfrom Islamic art and instructions which can be the turning point of architecture’s evolution in the field of Islamic art. In the present research, we have tried to study the instances of mosques’ architecture in Iran and contemporary world based on analyzing intellectuals’ perspectives toward Islamic art. Through this research, It is expected for researchers to tangibly comprehend the process of evolution in mosques and Islamic centers’ architecture as the most fundamental sign of Islamic art in world and in the modern era, and to clarify that in comparison to various interests of world’s designers and architects, which patterns of Islamic art hidden in these signs are more stable.","PeriodicalId":14142,"journal":{"name":"International journal of engineering and technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87158354","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}
