The research aims to know the impact of science, technology, engineering, and mathematics education on both creative thinking and mathematical achievement. To achieve it, the two researchers followed the quasi-experimental approach with an experimental design for two groups, one experimental and the other a control. The research sample consisted of (32) female students from the fourth scientific grade in Al-Intisar Preparatory School for Girls / Al-Rasafa, First Directorate. The sample was chosen intentionally and was divided into two groups: a control group studying by the traditional method, their number (16), and an experimental group that applied the STEM approach, their number also (16). There was parity between the two research groups in the variables (chronological age, previous achievement in mathematics, innovative thinking). The research tools consist of testing innovative thinking skills (fluency, flexibility, originality, relationships) and achievement tests. The research experiment was applied before and after. To test the validity of the hypotheses, data were collected and then statistically analyzed using appropriate statistical methods. The results of the research found that there were statistically significant differences in both the tests of innovative thinking and mathematical achievement in favor of the experimental group that studied according to the STEM approach, and in light of the results, the researchers recommended several recommendations and suggestions.

In light of the advanced technological development in the world, this study aims to use alternative energy for generating electric energy at the lowest cost. Solar cells are devices that have special operating conditions. The most important of these conditions are the temperature of cells and the intensity of solar radiation. Sometimes the climate condition does not match the ideal conditions used for operating solar cells in many regions around the world. Although the Middle East and Iraq in particular, is considered one of the sunniest areas in the world, solar energy cannot be relied upon to generate electric energy effectively because of the problem of high temperature in solar cells in the summer as well as the problem of dust. In this paper, a simple and economical method was designed to overcome the main problems in the operation of solar cells represented by high temperature in solar cells as well as the problem of dust accumulated on the surface of solar cells which impedes the entry of sunlight into those cells. The method is conducted by immersing the solar cells in running water at a distance that should be close to the surface of the water.

In view of the increasing demand for electric energy, parallel to global warming and increasing temperatures in the world, efforts must be made to find new and environmentally friendly ways to produce electric energy and eliminate the burning of fossil fuels. In this paper, we propose to approve hybrid plants for the production of electric power in Iraq due to the availability of the privileged location and the amount of clean energies that can be invested. We have chosen a small area located in the south of Iraq and suggested the establishment of a hybrid plant between solar energy, wind, and the national grid, and the results were very impressive, where at a very low cost it is possible to cover the district's need of electricity and export the rest to the national grid at a price (0.015 kwh). We chose this type of station, wherein in the daytime, it is possible to take advantage of solar energy, as well as wind energy, if available. And wind energy can be used at any time when there is wind at a speed higher than 3 m/s, where energy can be generated at night hours and the absence of sunlight for any reason. This study was carried out with the help of the NASA space website and the Homer program to study renewable energies.

Due to underground environments, wear and tear, rats, etc., underground cables are vulnerable to a large range of faults. It's difficult to diagnose the cause of the fault and the whole cable must be separated from the ground to inspect and repair faults. The project work is intended to use the ESP32 controller for detecting the fault location in underground cable lines from the base station in kilometres. The cable needs to be checked for faults to find a fault in the cable. The basic principle of Ohms law is used in this prototype. The current will vary based on the cable 's fault length. In big cities, instead of overhead wires, the electrical cables run underground. It is hard for detecting the precise location of the fault for the repairing phase of that specific cable if the fault occurs in it underground cable. The suggested device finds the precise the fault position. The system is designed with a group of resistors representing cable length in km and a set of switches are generated to cross check the accurateness of the same at any known distance. The voltage across series resistors changes accordingly in the case of a problem, which can then be transferred to an ADC to produce accurate digital data by using programmed C++ that further displays fault position in the distance. The distance, phase, & time of the fault is shown on a computer or mobile device using the internet. The IoT is used to show information on the internet by using ESP32 WiFi module. The website is generated using HTML coding and the fault information is displayed on the website.

According to future predictions, reliance will be largely on solar panels to provide electrical energy. Given its importance, the factors that maintain or increase its efficiency must be studied. Among the factors that reduce its efficiency are temperature, shade, dust and many others. The effect of the temperature on the performance and efficiency of a photovoltaic (pv) panel is the one of the main important facing the renewable energy, especially in hot regions, e g. South part of iraq. The high temperature to which the pv module is exposed in hot weather reduces the open circuit voltage and the efficiency. In this work, use two methods for cooling, namely water cooling and air cooling. The first method of cooling was air cooling by using dc fan that placed in the back of pv module. While the second method water cooling divided in two techniques, the first technique done by using two pieces of aluminum for cooling (water cooling blocks) placed in the rear of pv module and the second technique of water cooling by using copper perforated tube for spraying water placed in the front of pv module. The average of experimental results shows that the use of technique spraying water cooling are highest enhancement in efficiency than others techniques (water cooling blocks and dc fan) and more effective at high pv temperatures.

The result of the designed controller shows that the system has remained stable (remained vertically) and very fast (less than 1sec) until the system reaches the desired output.

The majority of the existing gases constitute a risk to the health of humans and the environment in general. There is a wide range of diseases that can arise as a result of exposure to toxic and dangerous gases, which can be a cause of death or serious health problems. More so, deadly explosions may occur as a result of leakages of such gases. However, such consequences can be avoided when these dangerous gases are not detected early. Many researchers have proposed different kinds of systems for the detection of gas leakage, but most of the proposed systems were mainly designed to detect LPG gas. Therefore, in this study, a system is proposed for detecting different kinds of flammable and toxic gases. The gases that are detectable by the proposed system include smoke, Ethanol, CNG Gas, Methane, toluene, propane, Carbon Monoxide, acetone, Hydrogen Gas, and Formaldehyde. The system can detect gases efficiently and release evacuation alarms simultaneously, then send SMS for emergencies. The proposed system is ready to use and can be installed at any work location.

What the world is seeing about the deterioration of public safety in various cities and the increase in the rate of crimes against children makes parents constantly worry about their children when they go to school and until they return from it. To dispel these fears, the idea emerges to create an application that allows parents to know the whereabouts of their children and notify them with a message if the children exceed the area specified for them. In this application, the process of discovering the child’s precise location in a specific area is carried out by determining the latitude and longitude using the GSM radio navigation system. After that, the mobile receives all the information about the location via the GSM modem. A GSM modem has been programmed to achieve communication between the modem and the child by two methods of communication through which the child’s location is determined. Ensuring that the child’s location is known at any time and informing the person responsible for tracking him is the primary function of this system. This device connects to the child in an appropriate manner and it turns on when the child exits the designated area for him, after which a message is sent to the tracker. The device can be triggered using a short messaging system (SMS) where the user can communicate remotely to the GSM using a mobile.

The cloud computing system has a significant role in the distance education field, because it is an important tributary of virtual education, especially mobile and blended education. Perhaps, the only challenge that must be overawed is the comprehensive coverage of rapid access to the Internet. So, the student can benefit from the applications that we will call from now and onward cloud computing services. There is no need to establish evidence to emphasize the importance of employing technological innovations to develop educational practices for developing educational curricula in Iraqi universities, but it is vital to employ technological innovations in the educational process, and this must be related to overcoming the problems facing the educational process. Therefore, employment should not be for technological dazzling that often accompanies technological innovations, but employment must be a function of urgent needs or demands. In this study, the educational process concept, with its multiple cloud inputs and outputs, was discussed how the education crisis could be overcome in all its institutions by resorting to how to employ the electronic cloud in distance education. This study also examined all the specifications of that environment and the possibility of their application in colleges and educational institutions.

RF Waveguide taper have a significant role in radar or communication systems through the use of it for joining two waveguides that have different cross sections, and this difference may be in dimensions of cross section or in the shape of it. the tapering may be from rectangular to rectangular waveguide (i.e. each waveguide operating at a certain frequency), or transition from rectangular to circular or elliptical waveguide. In this paper; two rectangular to rectangular waveguide tapers have been fabricated to join waveguide operating at C band frequencies with another one operating at X band frequencies. The fabricated tapers have the same shape but differ in length (8 cm, and 16 cm) in order to measure the effect of length on the most important parameters that have an effect on the performance of the taper, like voltage standing wave ratio "VSWR", return losses, and input resistance. Many tests have been done using two - port network analyzer. The results of the tests indicate that there is no effect on the performance of the waveguide taper although there is an extra 8 cm in length.

Streaming of video over wireless heterogeneous networks coping with the problem of packet loss which affects the perceived video quality. The service providers usually use the Peak Signal to Noise Ratio PSNR as a metric measure for the quality of their provided service. So they use the quality of service QoS of the network as a sign on the quality of their presented service. The QoS deal with the objective tests of the provided service, which mean the measure of PSNR of the presented objects. The presented objects may not get the satisfaction of the network users due to many factors although that the PSNR of the used service is enough for presenting the service. Recently the service providers use the Quality of Experience QoE term which deal with the subjective test of the presented object (i.e. the user satisfaction measure). In this paper we propose a new model to identify the importance or the significance of the role of the QoE assessment for the service providers. To verify our proposed model we did a referendum for 55 participants in order to assess their judgment on the quality of some presented videos. The results of the referendum match the consideration of the proposed model.

Standard horn antennas are an important device to evaluate many types of antennas, since they are used as a reference to any type of antennas within the microwave frequency bands. In this project the fabrication process and tests of standard horn antenna operating at X-band frequencies have been proposed. The fabricated antenna passed through multi stages of processing of its parts until assembling the final product. These stages are (milling, bending, fitting and welding). The assembled antenna subjected to two types of tests to evaluate its performance. The first one is the test by two port network analyzer to point out S & Z parameters, input resistance, and the voltage standing wave ratio of the horn, while the second test was done using un-echoic chamber to measure the gain, side lobes level and the half power beam width. The results of testing come nearly as a theoretical value of the most important of antenna parameters, like; gain, side lobe level, -3 dB beam width, return loss and voltage standing wave ratio "VSWR", input Impedance.
