In this study, domestic wastewater sludge was utilized in concrete production as partial cement changing with different ratios (0, 5, 10, and 15) % with dry sludge. The study showed that the compressive strength test showed that the partial replacement of cement by dry sludge caused reduction increased directly with the increase of sludge ratio compared with concrete reference specimens. The study found that dry sludge can be …

Identifying Risk Factors Influencing Traffic Accidents For Baghdad Expressways, Hasan Joni, Mustafa Jasim

Engineering and Technology Journal

In this paper, the SPSS program (version 25) and Binary Logistic Regression Model were used to implement and identify the risk factors that affect traffic accidents on Baghdad highways. Due to the increase in the number of traffic accidents that led to injuries and deaths in Iraq during the past years and the lack of specialized studies in traffic accidents, especially on highways, this required the preparation of a study to know the causes of accidents and to explore the factors that have a relative impact on (the severity of the accident). Four highways in the capital, Baghdad, were chosen …

Numerical Simulation Of The Effect Of Repeated Load And Temperature On The Behavior Of Asphalt Layers, Hind Akram, Miami Hilal, Mohammed Fattah

Engineering and Technology Journal

Roads and highways are used by different vehicle types, and the heavy vehicles among them can be considered the most critical in loading, which causes failure in the pavement structure and increases rehabilitation and maintenance costs. In this study, the composite effects for wheel loads and temperature were considered in the finite element analysis using Abaqus 6.14. The asphalt layer was modeled as an elastic material, while the base and subbase layers were modeled as an elastoplastic material following the Mohr-Coulomb model. Also, the impact of wheel loads on flexible pavement settlement and the main output of analyzing pavement structure …

A Proposed Wot System For Diagnosing The Infection Of Coronavirus (Covid-19), Dalal Thair, Akbas Ali

Engineering and Technology Journal

Coronavirus is one of the viruses that have broadly affected humans and the health system in general. The problem is that there is no treatment for the virus yet, and the virus spreads very quickly through coughing or touching. Therefore, patients infected with this virus must be isolated in their homes or designated care places. Therefore, the research aims to find appropriate methods to diagnose people with the virus remotely to avoid "mixing and trying to determine the virus's focus spread by presenting a new framework for e-health to identify Coronavirus patients. Since the web of things (WoT) is helpful …

Improving Machine Learning Performance By Eliminating The Influence Of Unclean Data, Murtadha Ressan, Rehab Hassan

Engineering and Technology Journal

Regardless of the data source and type (text, digital, photo group, etc.), they are usually unclean data. The term (unclean) means that data contains some bugs and paradoxes that can strongly impact machine learning processes. The nature of the input data of the dataset is the most important reason for the success of the learning algorithm. More than one factor influences machine learning results in a specific task. The characteristics and the nature of the data are the main reasons for the algorithm's success. This paper generally examines data processing entered into an algorithm to learn machines.

Moderating Effects Of Leadership Style And Organizational Culture On Information Technology Involvement, Erick Dyson

Walden Dissertations and Doctoral Studies

This quantitative correlational study investigated the relationships among leadership styles, organizational culture, information technology involvement (INV), IT adoption intention (ITA), and knowledge-sharing intention (KSI) among managerial staff in educational institutions in the northeastern United States. Grounded in the technology acceptance model (TAM) and knowledge management theory, the study utilized survey responses from 141 participants in supervisory roles. Regression analyses revealed that INV significantly predicted ITA (F = 31.725, p < .001), accounting for 17.7% of the variance. However, ITA demonstrated a statistically significant but inverse relationship with KSI (F = 7.995, p < .001), indicating that greater ITA was associated with lower KSI. Hierarchical regression showed that the inclusion of leadership styles and organizational cultures improved model fit, with the final model explaining 53.3% of the variance in KSI. Charismatic, transformational, and transactional leadership styles moderated the ITA and KSI relationship, while servant and transactional leadership directly predicted KSI. Among cultural types, hierarchy and market cultures moderated the ITA and KSI relationship, while adhocracy, hierarchy, and market cultures directly predicted KSI. Seventeen significant two-factor interactions were identified, highlighting the complex interplay of leadership and culture. Reliability analyses confirmed acceptable internal consistency (α = .71 -.85), and regression diagnostics indicted no assumption violations. These findings challenge traditional TAM assumptions and emphasize the need for context-aware strategies integrating leadership and culture to enhance knowledge sharing in digitally transforming institutions.

Towards Sustainable Energy Storage: Evaluating The Performance Of Three Polymer Electrolytes For Zinc-Ion Batteries, Roya Rajabi, Shichen Sun, Buke Sun, Jamil A. Khan, Kevin Huang

Faculty Publications

Polymer electrolytes have been explored as an alternative to conventional aqueous electrolytes in zinc-ion batteries, particularly for flexible and wearable applications. Despite the increasing interest in polymer electrolyte-based zinc-ion batteries (ZIBs), their development is still in its early stages due to various challenges. In this study, we investigated three promising polymer electrolytes: CSAM (carboxyl methyl chitosan with acrylamide monomer), PAM (polyacrylamide monomer hydrogel electrolyte), and p-PBI (phosphate-doped polybenzimidazole solid electrolyte) with Zn(ClO₄)₂ and Zn(OTf)₂, as electrolytes for zinc-ion batteries. The p-PBI solid electrolyte showed high mechanical stability and improved resistance to short-circuiting during cycling. The …

Time Invariant Variables In The Mundlak And Hausman-Taylor Panel Data Models, Badi H. Baltagi, Long Liu

Center for Policy Research

This paper shows that the classic augmented Mundlak (1978) regression yields the between estimator for time-invariant variables. It is well known that the estimates of the time varying variables yield the fixed effects estimates. While the latter are consistent for this correlated random effects model, the between estimates are not. The between estimator is consistent only when the Hausman (1978) test does not reject the null based on between versus fixed effects. An alternative modified Hausman and Taylor (1981) estimator is proposed. Monte Carlo experiments are performed to compare various estimators under a correlated random effects as well as a …

We experienced a 45-year-old male with ADPKD who developed spontaneous retroperitoneal hemorrhages with hypertension in the right subcapsular renal space without trauma. After his condition worsened with conservative management, he was treated by renal transarterial embolization (TAE). Over the next eight years, he experienced bilateral bleeding at three different sites and underwent repeated endovascular treatment with renal TAE to stop the bleeding. After the fourth occurrence, the patient underwent hemodialysis. Although renal cysts and urinary tract bleeding occur frequently in ADPKD, retroperitoneal hemorrhage is rare; however, TAE is both effective and a good way to preserve renal function.
