The experiment was carried out at the College of Agriculture-University of Kirkuk during the agricultural seasons 2018 and 2019 to study the effect of speed and depth of ploughing on some technical indicators of mechanical unit and physical soil characteristics using a rotary plough. The experiment included 12 treatments, which are the compatibilit...

In both centralized and decentralized air-conditioning systems, the performance, sustainability, and efficiency of the systems in delivering thermal comfort within a specific area are assessed as part of the air thermal management platform evaluation process. The evaluation of air thermal management platforms entails a thorough examination of numer...

To assess and forecast the operational performance of a modified car seat for thermal management using an air conditioning system, statistical and machine learning (ML) models were used. By extending evaporator/condenser coils beneath the back and cushion surfaces of the car seat and using operational data on the HVAC system, such as seat temperatu...

Abstract: In the pursuit of developing efficient and sustainable renewable energy systems, the design and optimization of heat sinks play a crucial role. This study focuses on the simulation and analysis of heat transfer coefficients for rods of different diameters and materials, with the objective of enhancing the performance of renewable energy s...

In recent years, researchers have paid special attention to wall uniformity temperature and improvement in a micro-combustor (MC) for applications as thermos-photovoltaic (TPV) since they have a direct influence on feasibility and efficiency of the required conversion of energy. Numerous experimentation and numerical studies in the field of mic...

Simulation is an essential interactive computer tool that can be applied to monitor systems graphically. A simulation of motion is presented in this study to support the control of Segway Robot Transportation Platform (SRTP). The introduced system provides simulation of the SRTP using MATLAB. The nonlinear dynamic equations of the motion for the Se...

Abstract Computational fluid dynamics, especially based on finite volumes method, is currently an industrial standard tool for thermal and hydraulic systems. Engineers, researchers, and sometimes graphic designers use this tool, mostly through commercially available software packages. However, computational fluid dynamics has serious limitations. T...

Robotic manipulators are widely used in applications that require fast and precise motion. Such devices, however, are prompt to nonlinear control issues due to the flexibility in joints and the friction in the motors within the dynamics of their rigid part. To address these issues, the Linear Matrix Inequalities (LMIs) and Parallel Distributed Comp...

Dynamics Modeling and Motion Simulation of Segway Robotic Transportation System

An experiment was carried out at the Agricultural Research and Experiments Station in the Sayyada Region of the College of Agriculture - University of Kirkuk, in order to study the effect of forward tractor speed and depth of ploughing in some technical indicators and physical properties of soil in Loam soils in 2019. Two factors were studied, dept...

A field experiment was carried out in one of the plastic houses of the College of Agriculture, University of Kirkuk during the 2018-2019 agricultural season, to study the effect of three cultivation distances and three cucumber hybrids Cucumis sativus L. hybrids and their interaction on some of the characteristics of the cucumber plant using the dr...

Delamination is the most common failures in composite structures and has harmful effects on the structure integrity. As such, a proper monitoring systemof delamination crack propagation is an urgent need for advanced composites structures invarious engineering applications.This paper details an investigation performed on the use of Thermal Stress A...

Aerial Robot Arms (ARAs) enable aerial drones to interact and influence objects in various environments. Traditional ARA controllers need the availability of a high-precision model to avoid high control chattering. Furthermore, in practical applications of aerial object manipulation, the payloads that ARAs can handle vary, depending on the nature o...

Pressure sensors, converting pressure force to electrical outputs such as 4-20 mA or 0-10 V, are used in a vast variety of areas while being facing numerous challenging thermal conditions. A common way is to design a heat sink for establishing natural convection cooling to protect the sensor. This work assesses a heat sink design and conveys its pe...

This paper details a study which was carried out on the application of FBG sensors for investigation of delamination crack status in glass fibre reinforced composite materials. A woven glass (0/90) epoxy composite sample containing a purposely created delamination and an embedded FBG sensor was investigated to study the behaviour of delamination cr...

Embedded fiber Bragg grating (FBG) sensors have been widely used for damage monitoring of fiber composite structures for a few decades. However, many remaining engineering challenges have delayed FBG based in situ structural health monitoring (SHM) systems. One of the major problem associated with FBG based SHM system is the unavailability of relia...

Mode I fracture analysis being employed to study delamination damage in fibre-reinforced composite structures under in-plane and out-of-plane load applications. However, due to the significantly low yield strength of the matrix material and the infinitesimal thickness of the interface matrix layer, the actual delamination process can be assumed as...
