Abstract: In this paper, we define ii-open set in bitopological space as follows: Let ( , , ) be a bitopological space, a subset A of is said to be ( – ii- open set ) if there exist U,V ≠ and U,V such that: A=int1(U) or A=int2 (V) A or A We study some characterizations and properties of this class. Also, we explain the relation between ii- open sets and open sets, i-open sets and α-open sets in bitopological space. Furthermore, we define ii- continuous mapping on bitopological spaces with some properties.
Abstract: Let R be a commutative ring with identity. We consider ΓB(R) an annihilator graph of the commutative ring R. In this paper, we find Hosoya polynomial, Wiener index, Coloring, and Planar annihilator graph of Zn denote ΓB(Zn) , with n= pm or n=pmq, where p, q are distinct prime numbers and m is an integer with m ≥ 1 .
Abstract: One of the most important problems that a teacher faces when using a smart board in the teaching process is the fall of a strong light beam from the projector on their faces and bodies. The focus of this light is harmful to the human eye, which leads to temporary blindness when it falls directly on the eye. It also leads to harmful side effects. The light falling on the presenter body will make the picture on the screen looks unprofessional and unclear and distract the attention of the students. Solving this problem will led to better lectures delivering for both the teachers and the student. In this study, a system is designed to track the movement of the teacher using an infrared transmitter that is attached to the teacher’s freshness or head cap. Electronic signals directed to an infrared receiver are installed on the front of the projector device in order to send these signals to the computer for analysis according to the proposed algorithms to determine the teacher face position. A black shade square) is placed in the designated and displayed on the smart board where the lighting will decrease on the face and eyes of the teacher, as this shade will be moving with the movement of the transmitter. This method aims to protect the teacher’s eyes from the harmful strong light.
Abstract: Biometric images are considered as one of the major coefficients in the field of personal authentication. One of the main approaches for personal identification is based on palm print. So studying the features extracted from palm print image adopted to get high efficient system for any recognition systems. In this research two major phases are hold on, in the first phase a database was built for 100 persons by acquiring four images for both hands (4 for left hand and 4 for right hand), then processed to extract ROI (region of interest) by looking for the palm centroid then a square area is fixed based on that centroid. The pre-process play an important step for stable features. Evaluation of the seven moments for each image (8 images) follow the preprocess then stored in the database file (so each person will have 56 values), this phase called personal database preparation. The second phase is the detection phase, which requires the same steps to get 56 values then go through the database looking for the closest person to the tested one. The system evaluation measured by statistical metrics which show good result goes up to 95.7% when applied on 50 persons with different conditions. Also the effect of ROI dimension with individual hands and integrated both of them studied, and the recommended dimension is 192*192.
Abstract: Due to the increase of development in modern technology which entered in most fields of life including sustainable agriculture; most studies revealed that most lesions result from over irrigation which causes fungi in plant and soil salinity. Recently; some very important terms emerged and changed most agricultural concepts such as the sustainable agriculture, green cities and smart irrigation systems. Most of these systems improved the quality of production and reduced lesions. In this paper a smart irrigation system was designed depending on Field Capacity F.C value, Wilting Point W.P value. In addition to the ranges of moisture that are measured in the field which are important in decision making of irrigation and selecting the best values to rely on such as threshold value in designing for the sake of maintaining moisture in the soil permanently. The best field moisture value was recorded when designing was %24 at threshold value in a clay soil field. Finally; the best types of microcontrollers ESP8266 & ESP-32S and moisture sensors, which are used to upload the data to Adafruit server. Also, the fast and light Message Queuing Telemetry Transport (MQTT) protocol, was used to transfer the ranges of moisture through the system and cloud computing.
Abstract: Blood donation (BD) is one of the most significant contributions that a person can make towards the society. The growing android technology has made the process of BD easier and hassle-free. The Nineveh blood bank is an android application made for such great and noble cause. The application connects the givers and the requesters of blood who live in the Nineveh province, Iraq. The blood requester can serach from a list of all donors who have the same blood group and directly contact them without any third-party involvement. The Nineveh Blood application creates giver’s/requester’s profile through the Google Firebase Real-time database. In which, a one WebSocket two-way channel can constantly send the data back-and-forth between the server and the clients, and store the data as a JavaScript Object Notation (JSON) file.
Abstract: The maintainability of the software is one of the most substantial aspects when assessing software product quality. It is known as the easiness with which the current software can be changed. In the literature, a great number of models have been suggested to predict and measure maintainability during various stages of the Software Development Life Cycle, to conduct a comparative study of the existing suggested models of the prediction, only few attempts have been done. This study hints at the basics about the manner of how to measure maintainability in the object-oriented (OO) design knowing that the maintainability will be measured differently at every level. Also, we will concentrate on the artificial intelligence technologies of these studies.
Abstract: The Holy Quran is a sea of words, articulations, phrases, regulations, laws, and judgments. Therefore, when we dive in the Quran verses we need a large amount of information in various aspects to achieve the required knowledge. The word (Al-Noor) is one of the Quran's vocabularies, which enjoys a special place, and this privacy came from the specificity of the Quran and its sanctity. The word (Al-Noor) has one pronunciation and many meanings and vocabulary. The research has sought to know God's lights: “the science, the guidance, the kernels, and faith “the closest and most intense and congregated of the verse (35/Al-Noor). Furthermore, this verse was chosen due to it speaks about the Sultan of Allah Almighty and god's light. Finally, the research has used the algorithm of “subtractive clustering and weighted subtractive clustering” measured and Matlab language (2013) to achieve the practical aspect of the study.
Abstract: This study aimed to use the cluster analysis to find the difference in the level of financial indicators of the National Insurance Company for the period (2008-2015) and to determine which financial indicators contributed significantly to this difference in the financial position of the company during the period under study. A cluster analysis method was used, represented by the hierarchical method (single link) and the method of averages (k-means). Where was concluded that the year (2008) had a low financial position for the company, while the year (2015) had an increase in the financial position of the company. And that the most important indicators that were the reason for the decline in the financial situation in the years (2008 and 2009) is the percentage of the company's contribution in other companies, while the rate of expenses and the rate of growth of the life insurance portfolio and the percentage of the company's contribution in other companies' were the most important factors that led to improvement The financial position of the company in the period (2010-2012) compared to previous years.
Abstract: The process of separating signal from a mixture of signals represents an essential task for many applications including sound signal processing and speech processing systems as well as medical signal processing. In this paper, a review of sound source separation problem has been presented, as well as the methods used to extract features from the audio signal, also, we define the Blind source separation problem and comparing between some of the methods used to solve the problem of source separation.
Abstract: Nowadays, the field of Internet of Things (IoT) has become a new trend and one of the most attractive areas of research. It has a wide range of applications; starting from smart devices to developing smart cities. The main issue in this kind of applications is the limitation in network resources (e.g., energy, memory, connectivity, etc.). Most of the works in the literature deal with this issue in a traditional way. For instance, developing routing protocols that find the optimal path for data forwarding. This paper looks to this issue from a different angle. In this work, we aim at testing different mobility patterns and then investigate their impact of the consumption of network resources under particular distributions and data routing protocols. The aspect we aim to investigate and measure is the amount of data exchanged, which in turn affects the power and the memory consumption of a network. We also measure two more aspects; performance stability, and data coverage area. The results show that mobility models play a significant role in the overall network performance.
Abstract: Dates are a great food that meets many human needs, and the government should encourage and intensify efforts to support the expansion of palm cultivation and development and focus on its production in our country as a means of food security in the future. In addition, palm trees have an important economic role in improving the country's economy. In this paper, a sharp decline in the quality of production will be highlighted. So, the aim of the study is to know the most important types of palm trees that affect the production of tigers for the year 2019 if the study includes 11 governorates, and the multiple linear regression method has been applied in selecting the most important types affecting the production.. and the types of palm trees did not appear Halawi and Khattawi and Khadari any effect on Dates production in the aforementioned year, although these types are considered to be one of the desirable first-class varieties in the Iraqi market, and for export in particular, in a manner that supports the country's economy.
