Due to the characteristics of the elevator system itself, traditional control algorithms are difficult to apply to elevator dispatching. However, the fuzzy control algorithm does not require the establishment of an accurate mathematical model, and can be well integrated with the elevator system. Based on fuzzy control, the elevator dispatch can be optimized. The traffic fuzzy inference controller is designed to identify the elevator traffic mode according to the flow of people; the elevator fuzzy inference device is designed to construct the objective function according to the evaluation index. Siemens S7-1200 series PLC is used to control the elevator, the elevator model uses Elevator Simulation Pro for simulation debugging, and Portal WINCC is used as the host computer for debugging to monitor.

Geographically, Soropia sub-district is located in Konawe district, Southeast Sulawesi, which consists of a large number of coastal areas which are transitional sites between land and sea. This condition has indirectly affected the shape of the area’s character caused by the relocation carried out by the government in an effort to build a tourist area in Bokori Island to move the coastal settlements in Bajoe Village, Soropia Sub-District. This coastal settlement is a form of reflection of the marine culture inherent in the Bajo people. One of the coastal settlements in the Soropia sub-district is a settlement in Bajoe Village with a building orientation towards land orientation. Due to this issue, in Bajo Village and its surroundings, there are three different site orientations in Luni coastal area including water-based buildings, semi-water buildings that tread on water and land, and land-based buildings. In addition, there is also a diversity of house functions in this coastal area which provide the characteristics of Bajo tribe’s coastal building identity in Bajo Village, Soropia Sub-District. To find out the diversity of the characteristics and identity of Bajo tribe’s coastal settlements in Bajo Village, a review of the typology is carried out.

Estimating the Reliability (Probability of Failure) of Reinforced Concrete (RC) structures in marine environments has been of major concern among researchers in recent years. While General (uniform) corrosion affects the reinforcement by causing a uniform loss of its cross-sectional area, Pitting (localized) corrosion concentrates over small areas of the reinforcement. Many studies have focused on the effect of general corrosion, the effect of pitting corrosion on the structure reliability has not been fully investigated. Furthermore, due to the variability associated with the parameters involved in the reliability estimation of the corroded structure, this paper focuses on the effect of variability of pitting corrosion on the structure reliability. The analysis also takes into consideration the Spatial Variability (SV) of key deterioration parameters often neglected in previous studies. The authors have used their experimental data in modeling SV parameters of a specific deterioration parameter. The analysis adopted here used Monte Carlo (MC) simulation technique to construct a Spatial-Time Dependent model to estimate the girder reliability. The results showed that pitting corrosion potentially has a far more aggressive effect on the structure reliability than general corrosion and that pitting corrosion affects shear resistance far more severely than it would affect flexure resistance. The analysis showed that after 50 years of service, the reduction in the beam reliability due to pitting corrosion was 51% higher than that caused by general corrosion and that considering SV has caused the reliability predicted in terms of pitting corrosion to decrease by 12%. In the case of general corrosion, the decrease in beam reliability was only about 2% for the SV scenario.

A pavement’s main role is to serve as a comfortable and safe riding surface for road users. Unfortunately, contractors often face a severe issue which is pavement distress. Pavement rehabilitation is a significant and improvable process, which regulates the road network’s function and is negatively impacted by deterioration. Considering the fact that pavement’s rehabilitation is a continuous and significant activity, there should be effective maintenance to prevent repeated and recurrent works. As such, in order to meet the goals of the pavement, this research aims to highlight the pavement defects’ sources and assess the effectiveness of pavement rehabilitation and maintenance efforts in terms of cost, time and quality within the Semarang Toll Highway district of Indonesia. Data collection involves collecting information from the bill of quantity, operation reports, contract documents and consultant reports. Following this, the information and presented and assess based on this study’s aim and objectives. In conclusion, some distress sources are identified to enhance the effectiveness of pavement rehabilitation and maintenance efforts within Semarang Highway.

Maxwell-like equations are offered that are valid not only for electromagnetic, but also for gravitational fields. They are based on an expanded form of the law of energy conversion, which explicitly takes into account the nonequilibrium of systems and the ability of energy to transfer from one energy carrier to another. This makes it possible to eliminate the distinction between electromechanics and the field theory, to find out the meaning of the magnetic vector potential as a function of the charge rotation speed, to reveal the tensor nature of the magnetic field and the presence of a divergent component of the scalar nature in it. The existence of the Lorentz magnetic forces and the presence of a work-performing moment therein are proved. Maxwell-like equations do not contain field operators and have a simpler form covering nevertheless a broader spectrum of phenomena due to taking into account the convective components of bias currents. Wave equations alternative to the Maxwell ones are offered and the non-electromagnetic nature of light is substantiated.

In recent years, housing prices across the country have been on a slow upward trend, and the real estate market is crisscrossed, and Shenyang is no exception. This paper chooses the Elman neural network that can process dynamic time series information to predict the trend of average housing prices in Shenyang. The article selects the average house price of Shenyang for 72 months from September 2015 to August 2021 in Shenyang, using 7 months as a set of training samples, the first 6 months as input data, and the seventh month as output data .There are 66 groups in total, the first 58 groups are used as training sets, and the last 8 groups are used as test sets. At the same time, the BP neural network and the RBF neural network are used for the same prediction, and the prediction results of the three are compared and analyzed. It was found that both the Elman neural network and the BP neural network are better than the RBF neural network in predicting performance. In terms of error details, since the Elman neural network can better process time series data, compared to the BP neural network, the predicted value of the Elman neural network is closer to the true value, and the predictability is better.

Porta Cabin Shelters are temporary dwellings constructed with Sandwich Panels, and used in operational sites by Oil and Gas Firms in Nigeria and Africa. This study carried out thermal performance analysis of Standard Porta Cabin Shelters used in Nigeria Liquified Natural Gas (NLNG) operational Sites using EN ISO 13786: 2017 and ISO 6946:2017 Calculation Methods and Procedures. The Calculation results were tested against the European Building Regulations Part L for compliance. This study reveals that the Porta Cabin shelters failed the compliance test. Analysis for possible compliance was undertaken and the outcome shows that construction of the roof, ceiling and walls with insulator (Sandwich Panels with Polyurethane Foam (PUF) as core materials thickness within the range of 80mm to 120mm) comply with the provision of European Building Regulations. Further analysis shows that adding about 80mm to 110mm thickness of insulator layer to the floor thermal layers will correct the major non-compliance in the floor construction and enhance thermal comfort of the shelters.

Further analysis shows that adding about 80mm to 110mm thickness of insulator layer to the floor thermal layers will correct the major non-compliance in the floor construction and enhance thermal comfort of the shelters.","PeriodicalId":379926,"journal":{"name":"Scholars Journal of Engineering and Technology","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133345936","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}
