Advances in Document Clustering with Evolutionary-Based Algorithms

Document clustering is the process of organizing a particular electronic corpus of documents into subgroups of similar text features. Formerly, a number of conventional algorithms had been applied to perform document clustering. There are current endeavors to enhance clustering performance by employing evolutionary algorithms. Thus, such endeavors became an emerging topic gaining more attention in recent years. The aim of this paper is to present an up-to-date and self-contained review fully devoted to document clustering via evolutionary algorithms. It firstly provides a comprehensive inspection to the document clustering model revealing its various components with its related concepts. Then it shows and analyzes the principle research work in this topic. Finally, it compiles and classifies various objective functions, the core of the evolutionary algorithms, from the related collection of research papers. The paper ends up by addressing some important issues and challenges that can be subject of future work.

Potential Use of Recycled Asphalt Pavement (RAP) in Hot MixAsphalt

The objective of the present paper is to examine the effect of Recycled Asphalt Pavement (RAP) on marshall properties and indirect tensile strength of HMA through experimental investigation. A mixture with 0% RAP was used as a control mix to evaluate the properties of mixes with 5%, 10%, and 15% RAP. One type of RAP was brought from Bab Al-moadam’s road in Baghdad for this purpose. The experimental testing program included Marshall and Indirect Tensile Strength tests. The results indicated that the bulk density, flow and VFA increase with the increasing of the percentage of RAP, while increasing in RAP results decreases in VTM and VMA values. Furthermore, the stability is changed from 10.1 kN for the control mix to12, 13.6 and 11.7 kN

The Privacy of public companies in Iraq: a comparative study

General companies are one of the methods that help managing general economic services. Countries have taken a step into this type of management because of the criticism-related to the different styles of managements. Criticism have been directed specifically at the direct type of management to such general economic services. Most of the Iraqi economic general services are being ran by this type of style; general type.

What has been agreed upon, whether in France, Egypt or Iraq has been that such establishments of general companies have to take place either by legislating a special order that states constructing a general company by the legislator or according to the law by authorizing law by the legislator to one of the local per

Percutaneous Transluminal Mitral Commissurotomy using Inoue Balloon in Iraqi population

 Background: Mitral stenosis (MS) is the most common valve disease in developing countries and there are many ways to deal with this condition. The aim of this study was to evaluate the immediate results of percutaneous transvenous mitral commissurotomy (PTMC) in patients with severe symptomatic rheumatic mitral stenosis.
Patients and Methods: From May 2006 to August 2007, 58 patients (17 male, 41 female) with age range (16-57) years, underwent PTMC in Ibn AL- Bitar Hospital for Cardiac Surgery. All the patients were symptomatic, their MVA 1.5 cm2 with NYHA class II-IV. Clinical evaluation and echocardiographic examination were carried out before and after PTMC, mitral valve structures were assessed

Iconic Form in Modern Graphic Design: علي محمد شواي غدير

The graphic field invests the visual space then shows the shape by all means of expression that have a certain meaning. The research is interested in studying the iconic form in the modern graphic design through investing names and flags and the extent of their action in the social life and invest them from one to another looked at from viewpoint of trading and consumption and investing their wide popularity. The study problem is manifested in the following question:
1- Does the iconic form help in ad circulation?
The importance of the research lies in the following:
1- Reading the visual iconic form through deciphering its current symbols. The form combines a concept and a case or a form and meaning.

Refused Derived Fuel RDF and its role in reducing production

Refuse derived fuel (RDF) is considered one of the most important types of low cost thermal energy which can be tapped in the industry, especially the cement industry in particular being the need of high thermal energy during the production processes, and in this paper we have implemented the use of a derivative of the fuel RDF  as a substitute for gasoline , to reduce production costs and thereby achieve production efficiency, and the methodology used in this research statistical analysis as well as the use of the cost of kaizen target for the purpose of reducing costs and achieve production efficiency, and this has reduced the cost total cement production by which led to reduce total costs of cement production by 8.4% and an incre

Predictive values of risk factors in management of diabetic foot

Background: Outcome of management of patients with diabetic foot is difficult to predict. Assessment of variables in history , examination and investigations were analyzed with outcome of management and whether can be assigned as prognostic factors .
Methods: prospective study of 300 patients with diabetic foot in Baghdad teaching hospital during the period from April 2000 to March 2004,certain criteria was taken in history and examination, these were investigated and treated either by conservative procedure or amputation.
Results: most common age group was 50-59 years ( 33.3%). The male to female ratio was 2:1. Conservative debridement was performed in ( 60%) of patients while amputation was employed in&nb

The role of quality of working life in regulatory alienation

Abstract

The goal of this research is to know the quality of working life and its impact on the level of the organizational sense of alienation among a sample of teaching Anbar University in the center of Baghdad. Find and seek to achieve a number of cognitive and practical goals.

Where the quality of work life constitutes one of the main sources to enable organizations of excellence in light of the volatile environment, as is one of alienation regulatory organizations avoid the phenomena that occur because of their negative effects on performance and thus achieve their goals. The most research problem in question the existence of the main deficiencies in the application of the concepts of organiz

Misleading Presentation of Colorectal Cancer in an Otherwise Healthy Patient

Background: Colorectal cancer (CRC) represents the second most common malignancy and the fourth most common cause of cancer deaths. CRC can manifest early with bright red bleeding per rectum, tenesmus, and altered bowel habits. These symptoms are often attributed to benign lesions, including anal fissure. Our objective is to highlight the alarming scenario of an anal fissure masking the clinical features of an underlying colorectal cancer in healthy middle-aged patients.

Case Report

Our case report aims to discuss how congruent clinical features of benign-looking anal fissure can delay the diagnosis of rectal cancer. In January 2019, a healthy forty-four years old Iraqi male with no famil

Study of Desertification using Remote Sensing Imagery in South Iraq

Recently The problem of desertification and vegetation cover degradation become an  environmental  global  challenge. This problem could be summarized as  as the land cover changes. In this paper, the area of Al- Muthana in the south of Iraq will be consider as one of Semi-arid lands. For this purpose, the Ladsat-8 images can be used with 15 m in spatial resolution. In order to over Achieve the work, many important ground truth data must be collected such as, rain precipitation, temperature distribution over the seasons, the DEM of the region, and the soil texture characteristics. The extracted  data  from this project are  tables, 2-D figures, and GIS maps represent the distributions of vegetation area
