This paper introduces enhanced filtered channels in the suggested design of the optical communication system formed for 5G mobile communication over optical fiber. The main goal is to overcome the limited bandwidth of radio wave systems and to enable high-data-rate transmission. The dense wavelength division multiplexing based on the radio-over-fiber (DWDM-RoF) system has succeeded in satisfying a high data rate of 0.64 Tbps by a multichannel filtered system through a 180 km distance within the C-Band through a multichannel filtered approach. The design includes 64 filtered channels with an optimized bandpass filter (BPF), making unprecedented channel convergence possible. The system transmits at low power 0 dBm (1.0 mW)

In this paper, a description of a design for new DES block cipher, namely DES64X and DES128X. The goals of this design, a part of its security level, are large implementation flexibility on various operating systems as well as high performances. The high level structure is based on the principle of DES and Feistel schema, and proposes the design of an efficient key-schedule algorithm which will output pseudorandomsequences of subkeys. The main goal is to reach the highest possible flexibility, in terms of round numbers, key size, and block size. A comparison of the proposed systems on 32-bit, 64-bit operating system, using 32-bit and 64-bit Java Virtual Machine (JVM), showed that the latter has much better performance than the former.

    Twenty-two of the Starling Sturnus vulgaris Linnaeus, 1758 were collected in Baghdad city during the period from January to September, 2014, and examined for endoparasites. Ten (45.45%) were found infected with either the cestode Passerilepis crenata (Goeze, 1782) (31.81%) or the nematode Dispharynx nasuta (Rudolphi, 1819) (13.63 %). Morphometric and meristic features for these worms were expressed. D. nasuta is recorded here for the first time from S. vulgaris for Iraq.

This research investigates the possibility of assessing and applying Malaysia's learning-information-base of successful private sector financing strategies for spurring economic growth in the Iraqi setting. The Malaysian model, especially with regard to support for small and medium enterprises (SMEs), is studied to chart the relevance and applicability of the concept to the Iraqi economy in the span of 2004-2023. Adopting descriptive-analytical and inductive method, the study brings forth Malaysia's diversified financing arrangements involving internal sources, external sources, public-private partnerships, and incentives with a specific aim. It is found that the Malaysian systems for its SME development, along with tax incentives and st

Background: Clinical classification of patients with acute coronary syndrome is essential step in identifying severe cases before referring them, fairly quickly, for the ultimate investigation of coronary angiography .Hence it is important to find out the extent at which the severity of the disease, based on clinical classification, agrees with its severity at angiography and to see whether traditional Risk factors or pas ischaemia played a role.
Patients and Methods : The angiographer data of 178 consecutive pts with Acute Coronary Syndrome (ACS) were retrospectively analyzed. The pts consisted of 114 with Unstable Angina (UA)  and 64 pts with Non-ST-Segment Elevation Myocardial Infarction (NSTEMI). Pati

This research examines the relationship between aggregate supply and inflation in Iraq during (2004-2023) through deviations in aggregate supply that lead to changes in output and inflation. The core issue of the research lies in how any change in aggregate supply results in a shift of the aggregate supply curve from its initial position. This study employed a deductive methodology, theoretical frameworks, descriptive and quantitative assessments, and econometric techniques to analyze the connection between aggregate supply, which is treated as a dependent variable, and inflation, categorized as the independent variable. The findings of the analysis validated the hypothesis and confirmed a statistically significant association between th

The origin of this technique lies in the analysis of François Kenai (1694-1774), the leader of the School of Naturalists, presented in Tableau Economique. This method was developed by Karl Marx in his analysis of the Departmental Relationships and the nature of these relations in the models of " "He said. The current picture of this type of economic analysis is credited to the Russian economist Vasily Leontif. This analytical model is commonly used in developing economic plans in developing countries (p. 1, p. 86). There are several types of input and output models, such as static model, mobile model, regional models, and so on. However, this research will be confined to the open-ended model, which found areas in practical application.

Abstract

This study aims to identify the degree to which the first cycle teachers use different feedback patterns in the e-learning system in addition to the differences in the degree of use according to specialization, teaching experience, and in-service training in the field of classroom assessment, as well as the interaction between them. The study sample consisted of (350) female teachers of the first cycle in government schools in Muscat Governorate for the academic year 2020/2021. The study used a questionnaire that contained four different patterns of feedback, which are reinforcement, informative, corrective, and interpretive feedback. The psychometric properties of the que

The child spends several hours watching animated films, which affect their behavior negatively and positively. This calls parents to monitor what their children are watching, to show them the serious risks of some violent films, and to direct them toward choosing both positive and educational programs that develop their positive behavior. This study aimed to explore the positive and negative effects of watching animation films as well as to identify the role animation films in increasing the cognitive knowledge of kindergarteners. To do this, the descriptive and analytical methods were used. A questionnaire was adopted as a tool for data collection. A scale of (45) items classified into three categories was applied on  the r

The research seeks to examine the ability of fifth preparatory students in solving a mathematical problem in relation to system thinking. To this end, the researcher chose (140) fifth preparatory students from four-different secondary schools in Kirkuk city for the academic year (2016-2017). Two tests were adopted to collect study data: a test of (5) items about skills in solving math problem designed by (Al-raihan, 2006); and a test of system thinking skills designed by the researcher himself consisted of (14) items. It was divided into four skills (analyzing the main system to subsystems, eliminating all inner gaps of system, identifying the inner connection of system, and reorganizing the system). The findings indicated a good ability

The current study examined the effect of different sample sizes to detect the Item differential functioning (DIF). The study has used three different sizes of the samples (300, 500, 1000), as well as to test a component of twenty polytomous items, where each item has five categories. They were used Graded Response Model as a single polytomous item response theory model to estimate items and individuals’ parameters. The study has used the Mantel-Haenszel (MH) way to detect (DIF) through each case for the different samples. The results of the study showed the inverse relationship between the sample size and the number of items, which showed a differential performer.

Background: women with acute coronary syndrome have increased in-hospital morbidity & mortality as compared with men following percutaneous coronary intervention (PCI). It remains unclear if this difference secondary to the sex or other confounding variables.

Patients and Methods: We sought to examine the characteristics and outcomes of 71 consecutive women (49.2%) and men (50.7) undergoing PCI at The Iraqi Center of Heart Diseases from October 2005 to March 2006.
