Usually buildings consume large amount of electricity for heating and cooling purposes, which can reach higher than 40%. Heat pumps are highly efficient devices that are used to lower energy consumption because they just require a little amount of electric power to trans-fer heat from a lower to a higher temperature source, which is the opposite of the natural flow. Green-house gas emissions can be reduced consequently if the electric power input is supplied from renewable energy sources such as hydropower, geothermal or solar energy. These devices can provide two to six times more energy output from the input energy required for system operation. Thermodynamic analysis is done for heating and cooling cycles of the heat pumps. Moreover, the different types and configurations will be discussed in addition to its various applications in real life. At the end, it is a useful device that can be used to lower energy consumption and emissions.

The current standard procedure for firearm examination is to compare two gunshot samples, one from the crime scene and the other from a firearm test shot. A bullet recovered at a crime scene can be studied using a comparison microscope, which allows a ballistics examiner to determine and compare the bullet to ascertain its source and if it was shot from the same firearm, which is a subjective analysis. The purpose of this research is to evaluate the approach of artificial intelligence for the examination of bullets to obtain an objective analysis. An effort was made through this research to evaluate the aims of artificial intelligence in forensic ballistics and to examine the class characteristics such as rifling marks and individual characteristics of a bullet and include a method of recommendation. The end-point objectives of this review are improvements and alterations to enhance the examination of a submitted bullet using the latest technological innovation such as a virtual microscope, quantum 3D microscope, and artificial intelligence expert systems. In conclusion, we discussed the use and relevance of advanced technologies to help obtain a reliable assessment of the bullet comparison other than the conventional methods.

The COVID-19 pandemic has imposed rapid and significant changes upon education systems. Most educational institutions transferred abruptly from traditional face-to-face delivery to distance learning formats through virtual classrooms. As a result of this shift, many faculty members have faced challenges in keeping their students engaged during lectures. Gamification is often proposed as a promising solution to enhance student motivation, engagement, and learning outcomes attainment. This study investigates the effectiveness of the gamification mechanism on undergraduate students in a computer programming course using Kahoot! and Nearpod during distance learning. The findings of the study show that there is some correlation between student engagement, learning motivation, academic performance, and the use of gamification.

A severity analysis is made to evaluate the effect of corresponding shock or transient vibration on the man on the vehicle passing through a series of road bumps. Road bumps cause undesirable human vibrations due to vehicle vibration meant to limit the vehicle speed. In this study, vehicle vibrations are first computed following the vibration analysis procedure, in which equations of motion are solved using MATLAB. A light vehicle is employed to record vibration measurement using a triaxial accelerometer setup indigenously with data acquisition using a laptop. The total vibration level received at the vehicle is evaluated through the design of the Vibration Nomograph based on ISO 2631 to assess the harmful and/or dangerous levels of vibration. It is found that if human beings are exposed to this level vibration for a more extended period of 12-h or more, they will be facing health hazards such as effects on the central nervous system and musculoskeletal diseases.

The prevalence of diabetes has been consistently increasing over the past decades. While implementation of sensor-based systems for managing diabetes is on the rise, manual monitoring efforts are still required in case of abnormal fluctuations in the blood glucose levels due to lack of intelligent systems. This paper presents an incremental research work developed on top of a previous work to build a smart system. The proposed system helps in managing Type-1 diabetes using future predictions to avoid hypoglycemia or hyperglycemia. It presents a smart healthcare device for diabetic patients with the ability of intelligently controlling the insulin dosage each time during automatic injection to maintain normal blood glucose levels. The system consists of an insulin pump, a continuous glucose monitor (CGM), and a microprocessor unit which utilizes artificial intelligence (AI) based algorithms to predict future blood glucose levels to avoid serious conditions. The prediction feature used in the proposed system distinguishes it from other commercially available products. Furthermore, the proposed system monitors the blood glucose levels of the patient and notifies the patient in case of critical conditions. It can also send a summarized report to the healthcare center and provide the patient with a timeline of collected data and insulin dosages injected. The device was implemented and tested with very good results.

This study aims to identify the drivers of patient safety challenges in healthcare. Hospital-level aggregate survey data from the UK hospital is used to identify what drives the number of reported incidents affecting patient safety. Leveraging a decision tree algorithm, our results suggest that the role of teamwork and safety culture in incident reporting and investigation are the most critical dimensions influencing the number of reported patient safety challenges. The decision tree algorithm can be useful for hospitals to enhance patient safety through data-driven approaches and direct resources towards service improvements.

In this paper, three different Rind Down analysis methods are used to pre-process an online wide-area damping controller. A modified Linear Prediction criteria (LPC) method is proposed to handle latency delay and data dropout in the communication channels, Prony and MC-Brid methods are used to estimate the eigenvalues of the low-frequency oscillation modes, and adaptive buffer size for Prony and MC-Bride methods is proposed to decrease the necessity to the offline damping controller. Then, the transfer function of the oscillation mode is extracted from these methods, and a simple order reduction technique is applied (zero-pole cancellation) to obtain a low order transfer function for the wide-area controller.

Concrete Filled Steel Tubes (CFSTs) have been studied and used for a long time since it confines the concrete inside which significantly increases its mechanical properties. Most current studies focus on the axial behaviour of CFST. Furthermore, there are few experiments that incorporate recycled and waste materials in the concrete mix of CFST beams. This study aims to evaluate the flexural response of CFST beams that incorporate Demolished Concrete Lumps (DCLs) in a unique arrangement to minimize their effect on different mechanical properties. Seven circular CFST specimen were casted and tested under bending using the four-point bending test, where the Universal Testing Machine (UTM) was utilized. Different DCL sizes and occupied areas are considered in this study. The CFST beams are evaluated by plotting moment vs. deflection and moment vs. microstrain curves, and the specimens are then compared by assessing the capacity, ductility, and stiffness.
