Modeling, Investigating, And Quantification Of The Hot Weather Effects On Construction Projects In Oman, Mubarak Khamis Al Alawi Apr 2025

Modeling, Investigating, And Quantification Of The Hot Weather Effects On Construction Projects In Oman, Mubarak Khamis Al Alawi

The Journal of Engineering Research

The construction industry is recognized as one of the industries most exposed to climatic conditions. Construction projects are mainly executed in an outdoor environment and the activities are considered weather-sensitive. Severe weather conditions can directly affect the productivity and efficient operation of construction projects. In addition, the weather is known to be one of the main factors that decrease labour productivity in construction projects causing project delays, cost overruns, and contractual claims between contractors and clients. Oman has a hot climate with very high temperatures in summer, warm winters, and low annual rainfall. During extremely hot weather, labour productivity significantly …

Modelling Of Electrical Submersible Pumps For Petroleum Multiphase Fluids, An Intelligent Approach Supported By A Critical Review And Experimental Results, M Mohammadzaheri, Reza Tafreshi, Zurwa Khan, Hamidreza Ziaiefar, Mojataba Ghodsi, Mathew Franchek, Karolos Grigoriadis

The Journal of Engineering Research

This paper initially reviews existing empirical models which predict head or pressure increase of two-phase petroleum fluids in electrical submersible pumps (ESPs), then, proposes an alternative model, a fully connected cascade (FCC in short) artificial neural network to serve the same purpose. Empirical models of ESP are extensively in use; while analytical models are yet to be vastly employed in practice due to their complexity, reliance on over-simplified assumptions or lack of accuracy. The proposed FCC is trained and cross-validated with the same data used in developing a number of empirical models; however, the developed model presents higher accuracy than …

In Achieving The Most Of Limited Research Budget For Engineering Research Projects: A Case Study At Sultan Qaboos University, M Zarog Apr 2025

In Achieving The Most Of Limited Research Budget For Engineering Research Projects: A Case Study At Sultan Qaboos University, M Zarog

The Journal of Engineering Research

Motivating engineering research in universities with limited or tight research budgets is a challenging task. There is always a conflict between researchers attempting to secure enough funds to ease their own research, and funding bodies and universities trying to achieve high quality research while lowering research expenses. This conflict leads to a situation where universities and researchers cannot achieve their goals altogether. This study attempts to partially resolve this issue by optimizing research expenditure for the benefit of both universities and researchers and suggests some policies regarding what type of research (modelling based or experimental based) universities should support. Other …

Carrier Based Pwm Technique And Adaptive Neural Network Based Rotor Resistance Estimator For The Performance Enhancement Of Vector Controlled Induction Motor Drives, Venkadesan A

The Journal of Engineering Research

In this paper, the carrier based Pulse Width Modulation (PWM) technique and neural network based rotor resistance estimator are proposed for vector controller Induction motor (IM) drives. The popular sine PWM is used for induction motor drive. The popular sine PWM has poor harmonic profile and (DC) utilization. The space vector modulation (SVM) technique overcomes the disadvantages of sine PWM. But SVM is computationally complex. Hence a simple PWM technique namely “carrier based PWM technique” similar to SVM is identified and proposed for vector controlled IM drive. The experimental set up is built up and the performance of carrier based …

Influence Of Exposure To An Aggressive Environment On Cyclic Fatigue Response And Life Of An Alloy Steel, Tirumalai Srivatsan, K. Manigandan, A. Patnaika, T.S. Srivatsan

The Journal of Engineering Research

Corrosion or environment-induced degradation often occurs in structural steel as an electrochemical process which leads to gradual loss in mass over a period when subjected to prolonged exposure to an aggressive environment. Immediate effects of this environment-induced degradation, also referred to in industry circles as corrosion, includes a progressive reduction of the cross section, which in turn has a detrimental influence on stiffness and load carrying capacity of the components in a structure, such as a bridge, a stiffened panel or a building. Due to its high strength, low alloy A572 Grade 50 steel is a potentially viable candidate for …

Design Of A Testing Facility For Investigation Of Drill Pipes Fatigue Failure, Jamil Abdo, E. Hassan, A. Al-Shabibi, J. Kwak Apr 2025

Design Of A Testing Facility For Investigation Of Drill Pipes Fatigue Failure, Jamil Abdo, E. Hassan, A. Al-Shabibi, J. Kwak

The Journal of Engineering Research

Drillstring and down-hole tool failure usually results from failing to control one or more of the vibration mechanisms. The solution starts with the ability to measure different modes of vibration, hence identifying different vibration mechanisms. Lateral, torsion and axial are vibration modes that take place when drill pipes run into problems downhole. Due to the three modes of vibration mechanisms such as bit bounce, stick-slip, lateral shocks, bit and bottom hole assembly (BHA) whirl, parametric and torsional resonance occur. Understanding the causes of the destructive loads is the main step towards developing approaches to prevent or reduce their effects, hence …

An Enhanced Smith Predictor Based Control System Using Feedback-Feedforward Structure For Time-Delay Processes, M. Mohammadzaheri, R. Tafreshi Apr 2025

An Enhanced Smith Predictor Based Control System Using Feedback-Feedforward Structure For Time-Delay Processes, M. Mohammadzaheri, R. Tafreshi

The Journal of Engineering Research

This paper presents enhanced Smith predictor based control systems (SPBCSs) for processes with a time-varying or fixed time delay. This work focuses on improving the arrangement and asynchrony of SPBCS components rather than the design of the predictor and the feedback controller, which have been well discussed in the literature. The proposed control system advances SPBCS through implementation of two design recommendations: (i) replacing the classical feedback controller by a feedback-feedforward control system, and (ii) synchronizing the reference signal and the predicted output. As a result, common shortcomings of SPBCSs or control systems based on Pade approximation, i.e. the …

Estimating Drilling Cost And Duration Using Copulas Dependencies Models, M. Al Kindi, M. Al-Lawati, N. Al-Azri

The Journal of Engineering Research

Estimation of drilling budget and duration is a high-level challenge for oil and gas industry. This is due to the many uncertain activities in the drilling procedure such as material prices, overhead cost, inflation, oil prices, well type, and depth of drilling. Therefore, it is essential to consider all these uncertain variables and the nature of relationships between them. This eventually leads into the minimization of the level of uncertainty and yet makes a "good" estimation points for budget and duration given the well type. In this paper, the copula probability theory is used in order to model the dependencies …

Stochastic Allocation Of Transmit Power For Realistic Wireless Channel Models, N. G. Tarhuni, M. Elmusrati, M. Al-Nadabi Apr 2025

Stochastic Allocation Of Transmit Power For Realistic Wireless Channel Models, N. G. Tarhuni, M. Elmusrati, M. Al-Nadabi

The Journal of Engineering Research

Control of transmitted power is crucial for the successful operation of multi-user wireless channels communications. There are practical situations in which the transmitted power cannot be adjusted by feedback information; hence, only forward transmit power allocation can be applied, especially in situations where a feedback channel is not available in a wireless network or when wireless nodes are only transmit types. Conventionally, transmitted power can be fixed. Higher gain may be observed if the sensors’ transmitted power is randomized. In this work, random power allocation for a Nakagami-m distributed wireless channel model was investigated, and a number of random distributions …
