Wavelet-Based Numerical Methods for Signal Processing
No full textModern signal processing makes great use of wavelet transforms since they provide a flexible way to examine nonstationary signals both across time and frequency. This study looks at the optimization and use of several wavelet transforms include dual tree complex wavelet, stationary wavelet transforms (SWT), discrete wavelet transform (DWT), and continuous wavelet transform (CWT). For jobs including denoising, compression, feature extraction, and time frequency analysis, transform (DTCWT) is used. The paper looks at the tradeoffs between how fast it works, how good it is, and how reliable it is when choosing the right transform for various kinds of signals, including pictures, ECG, and speech. Important issues covered are the retention of high frequency components, edge integrity, and look into sophisticated approaches like synchro squeezed wavelet transforms (SSWT) for better frequency tracking and wavelet Galerkin feature stability across signal types. The study also examines techniques for resolving partial differential equations. Through performance evaluation using parameters such Signations Ratio (SNR), Peak Signations Ratio (PSNR), and Structural Similarity Index (SSIM), the research gives fresh perspective on the optimum methods for using wavelet transforms to address practical signal processing challenges

pdf Observational Study on Breast Lump Cases in Iraqi Women Visiting the Breast Cancer Screening Unit at Al Elweiya Teaching Hospital in Baghdad: Dr. Lutfi Ghulam Awazli, Rafif Nemah Hassoni and najim Abid Issa
No full textBreast lumps or swelling are a common concern for women and carry potential risks, especially with the global rise in breast cancer cases. In Iraq, the incidence of breast cancer is increasing, notably impacting younger women. Common breast symptoms prompting women to seek medical attention include breast pain, nipple discharge, and palpable masses. Increased public awareness and enhanced screening methods have enabled earlier detection, allowing for treatment during stages where complete surgical resection and curative options are viable. This study aimed to examine the relationship between demographic and clinical factors and the presence of breast lumps, as well as to identify the age distribution of a study was conducted on women with palpable breast lumps who attended Al-Elweiya Teaching Hospital. This prospective study included 209 cases of palpable breast masses in female patients, assessed through a comprehensive evaluation process at the Tumor Women Center in Al-Elweiya Maternity Teaching Hospital between February and December 2023. Patients presenting with clinical signs of breast lumps underwent a thorough medical history, physical examination, and further assessment via mammogram, ultrasonography, FNAC, and/or core biopsy. Following diagnosis, patients were either scheduled for follow-up or definitive surgery. Among the 209 cases, the majority of patients (27.2%) were in the 41-50 age groups. Benign breast lumps accounted for 144 cases (68.8%), while 65 cases (31.1%) were malignant. A highly significant (P=0.001) association was observed between cases of malignant breast lumps and the 50-59 age group. Factors in married women who have fewer than five children, nipple retraction, and lymph node involvement showed highly significant correlations with breast lumps (P<0.01). Benign breast disease was the most prevalent diagnosis, with fibro-adenoma being the most common benign lesion. Breast cancer cases were less frequent, affecting about one-third of women and showing a trend toward younger age groups.
Mechanochemical synthesis of hydrazone lanthanide complexes to overcome the conventional method limitation
No full textThe synthesis of lanthanide (III) Schiff base complexes will use a solvent-less reaction as a broad method of producing chemical products without the need for solvents. Mechanochemical synthesis produced pure products directly and demonstrated quantitative conversion without any byproducts. Schiff base ligand synthesis using lanthanides (III). The reaction of isatinmonohydrazone with salicylaldehyde, which then reacted with lanthanide (III) chloride for forming complexes of Ln (HISA)2Cl3 type, in which HISA= [(2-hydroxy-benzaldehyde)-3-isatin] bishydrazone and Ln = La (III), Sm (III), Eu (III), and Gd (III). In vibratory ball-mill conditions, all reactions have been conducted. Magnetic susceptibility measurement, molar conductance, UV spectral data, and proton NMR spectral data were used for characterizing the complexes and the ligand. X-ray diffraction (XRD) was used for characterizing the structure of ligand and lanthanides (III) complexes. XRD pattern of the ligand showed its crystalline nature, whereas that of lanthanum (II1) complex showed its amorphous nature. The ligand served as a neutral tridentate, which coordinated through neutral, azomethine, and tridentate. The goal of this study is to develop environmentally friendly as well as economic process for the synthesis of some lanthanide(III) complexes with heterocyclic hydrazone, that avoid the use of solvent, minimize the formation of byproduct, with high yield, and short reaction time
The Impact of Past Stress on the Temporomandibular Joint: A Survey among First and Fifth Stage Dental Students at Dijlah University College: Amir A. Majeed
No full textThe present study aims to assess the prevalence of temporomandibular disorder symptoms among dental students at Dijlah University College and to investigate their association with sex, parafunctional habits, psychological stress, and anxiety. Additionally, it seeks to identify possible risk factors for the development of temporomandibular disorders, with a focus on students in the first and fifth stages of the dentistry program.
A cross-sectional study was conducted on a total of 434 dental students at Dijlah University College in Baghdad, Iraq. The sample included 167 fifth-stage students and 267 first-stage students, comprising 196 males and 238 females. Data was collected using a structured questionnaire developed by researchers, administered over a period of approximately four months, from December 1, 2023, to March 10, 2024.
The results indicated a significant correlation between temporomandibular joint disorders and gender, with a higher incidence observed in females compared to males. Additionally, the prevalence of temporomandibular joint pain was significantly higher among fifth stage students compared to first stage students. However, the intensity of pain was significantly higher in stage one students than in stage fifth students.
TMD is significantly (P<00) more prevalent in females than males. While TMJ pain is more common among fifth-stage students, its severity is greater (P<00) in first-stage (preclinical) students
The Limits of the Arbitrator’s Authority According to the Ottoman Civil Code
No full textهدف البحث إلى بيان حدود السلطة الممنوحة للمحكمين في مجلة الأحكام العدلية، وذلك من خلال دراسة مقارنة مع القوانين الوضعية الحديثة. كما سعى إلى بيان مدى توافق هذا النظام التقليدي مع مقتضيات العدالة والاستقرار القانوني في التحكيم. واتبع البحث منهجًا تحليليًا مقارنًا، معتمدًا على تحليل النصوص الشرعية والتشريعية الواردة في المجلة، ومقارنتها بالتشريعات الحديثة في الدول العربية، ودراسة الآراء الفقهية والقضائية ذات الصلة.
وخلص البحث إلى أن المجلة تمنح المحكمين صلاحيات واسعة مستمدة من اتفاق الأطراف، لا سيما عند تفويضهم بالحكم وفقًا لمبادئ العدالة. إلا أن هذه الصلاحيات ليست مطلقة، بل مقيدة بمعايير قانونية وأخلاقية، كمراعاة النظام العام، وعدم مخالفة القواعد الإلزامية، والالتزام بحقوق الدفاع والمساواة. كما أظهر البحث التباين بين اشتراط المجلة عددًا زوجيًا من المحكمين، واشتراط القوانين الوضعية عددًا فرديًا. في نهاية الدراسة، أوصى الباحث بتحديث النصوص المتعلقة بالتحكيم في مجلة الأحكام العدلية لتتماشى مع المعايير القانونية الحديثة. وأكد على تحديد صلاحيات المحكم بوضوح عند إصدار حكمه بما يتفق مع العدالة، وتعزيز ثقافة التحكيم كطريقة بديلة فعّالة تتسم بالإنصاف والمرونة، دون المساس بالضمانات الأساسية للمتقاضين.The research aimed to demonstrate the limits of the authority granted to arbitrators in the Majalla al-Ahkam al-Adliyya, through a comparative study with modern positive laws. It also sought to demonstrate the compatibility of this traditional system with the requirements of justice and legal stability in arbitration. The research followed a comparative analytical approach, relying on an analysis of the Sharia and legislative texts contained in the Majalla, comparing them with modern legislation in Arab countries, and examining relevant jurisprudential and judicial opinions.
The research concluded that the Majalla grants arbitrators broad powers derived from the agreement of the parties, particularly when they are authorized to rule in accordance with the principles of justice. However, these powers are not absolute, but are restricted by legal and ethical standards, such as observing public order, not violating mandatory rules, and adhering to the rights of defense and equality. The research also demonstrated the discrepancy between the Majalla\u27s requirement of an even number of arbitrators and the requirement of an odd number of arbitrators in positive laws. At the end of the study, the researcher recommended updating the arbitration-related texts in the Majalla to align with modern legal standards. He emphasized the need to clearly define the arbitrator\u27s powers when issuing an award in accordance with justice, and to promote the culture of arbitration as an effective alternative method characterized by fairness and flexibility, without compromising the fundamental guarantees of litigants

The obligation of notification as a direct legal mechanism for consumer protection within the insurance contract
No full textيُعد الالتزام بالإعلام أحد أبرز الضمانات القانونية التي توفر حماية فعالة للمستهلك خاصة ضمن عقود التأمين التي تمثل أحد أهم نماذج عقود الاستهلاك في العصر الحديث، ورغم أن الأصل في العقود الاستهلاكية أن يقع عبء الإعلام على عاتق الطرف المحترف – بوصفه الطرف الأقوى من حيث الإمكانيات والخبرة – فإن المشرع العراقي وإن لم ينص صراحة على التزام المؤمن بالإعلام ضمن إطار قانوني خاص بعقد التأمين إلا أن هذا الالتزام يُستفاد ضمناً من المبادئ العامة للقانون المدني العراقي رقم (40) لسنة1951، ومن قانون حماية المستهلك رقم (1) لسنة 2010.
وفي هذا السياق يُنظر إلى عقد التأمين بوصفه من العقود التي تتطلب شفافية ومصداقية عالية لما تنطوي عليه من آثار مالية ومعنوية كبيرة على المستهلك وهو ما يفرض على المؤمن واجباً جوهرياً بالإعلام عن كل ما من شأنه التأثير في قرار المستهلك (المؤمن له) بشأن التعاقد، ويهدف هذا الالتزام إلى تضييق فجوة المعرفة بين الطرفين، وتكريس مبدأ حسن النية والتوازن العقدي.
The duty of disclosure stands as one of the most prominent legal safeguards ensuring effective consumer protection, particularly in insurance contracts, which represent a significant form of consumer agreements in the modern era. While, in principle, the burden of disclosure in consumer contracts generally falls on the professional party—being the stronger party in terms of resources and expertise—the Iraqi legislator, although not explicitly providing for a duty of disclosure on the insurer within a specific legal framework for insurance contracts, implicitly recognizes this obligation through the general principles of the Iraqi Civil Code(law No.40 of 1951) and the Consumer Protection (Law No. 1 of 2010.(
In this context, the insurance contract is viewed as one that requires a high level of transparency and good faith, due to the considerable financial and moral consequences it may have for the consumer .This imposes a fundamental duty on the insurer to disclose any information that could influence the consumer’s (the insured’s) decision to enter into the contract. The purpose of this obligation is to bridge the knowledge gap between the parties and to uphold the principles of good faith and contractual balance
توافق القرآن الكريم مع الحقائق والنظريات العلمية المعاصرة
No full textتتناول هذا البحث موضوع توافق القرآن الكريم مع النظريات العلمية المعاصرة وهو من الموضوعات ذات الأهمية الواسع والمثير حيث يتناول العلماء والمفكرين العلاقة بين النصوص القرآنية والاكتشافات العلمية الحديثة . ويُعد هذا البحث محاولة لفهم مدى انسجام ما ورد في القرآن الكريم مع ما توصلت إليه العلوم في مجالات متنوعة مثل علم الفلك والطب وعلم الاحياء والفيزياء .
يجب ألّا يتوقّع أحد أن يُبيّن القرآن الكريم جميع مسائل العلوم الطبيعيّة وأسرار وخواصّ كلّ الأشياء، لأنّ القرآن لم ينزل لبيان هذه الامور، فهو ليس دائرة للمعارف أو كتاباً لعلم طبقات الأرض (الجيولوجيا) أو لعلم النبات، وإنّما هو كتاب للتربية والهداية، نزل ليقود الناس إلى حياةٍ نقية مقترنة بالسعادة والفضيلة ويحكمها الصدق والأمانة والنظام والرحمة، وليوصلها في النهاية إلى القرب من اللَّه تعالى. (الشيرازي ، 2014 ، ص123).
يتناول موضوع "توافق القرآن الكريم مع النظريات العلمية المعاصرة" العلاقة بين النصوص القرآنية والمكتشفات العلمية الحديثة، موضحًا كيف ينسجم الوحي الإلهي مع القوانين والنظريات التي تم التوصل إليها في عصرنا. يُعد هذا التوافق دليلاً على مصدرية القرآن الإلهية، حيث يتضمن إشارات علمية دقيقة سبقت عصر الاكتشافات بقرون، مما يجعله كتابًا خالدًا صالحًا لكل زمان ومكان.
يُركز الموضوع على الإعجاز العلمي، الذي يعني تقديم القرآن حقائق علمية لم تكن معروفة في زمن نزوله، ولكنها اكتُشفت لاحقًا بفضل التقدم العلمي. على سبيل المثال، تشير الآيات المتعلقة بخلق الإنسان وتكوينه في مراحل محددة إلى دقة مذهلة تتوافق مع علم الأجنة الحديث. كما تناولت آيات أخرى موضوعات كونية، مثل نشأة الكون واتساعه، وهو ما أكده علم الفلك المعاصر
