The maintenance and repair of existing concrete structures in the field of civil engineering is very important and it needs engineers with broad experiential knowledge. The difficulties of structural damage assessment, diagnosing distresses and obtaining recommendations on materials and procedures for repair are sometimes more complicated. Seeking to apply a single form of knowledge representat...

Manual surveys still represent the most widely used means for inspecting and evaluating pavements. Manual rating of pavements through windshield surveys to identify the types of surface cracking and other distresses leads to relatively slow evaluation. Furthermore, the survey crew must sometimes physically be in the travel lane to evaluate the pavement, exposing themselves to hazardous conditio...

Polycystic Ovary Syndrome (PCOS) is a female endocrine disorder which severely distresses women’s health. The disorder is characterized by a collection of incomplete developed follicles in the ovaries. Manual analysis of PCOS diagnosis often produces errors. So, in recent years many researchers have been enthusiastically working in automatic detection of PCOS. This paper reviews follicle detect...

BACKGROUND Leukemia and hematopoietic stem cell transplantation (HSCT) create physical, psychological, social, and spiritual distresses in patients. Understanding this threatening situation in adults with leukemia undergoing HSCT will assist health care professionals in providing holistic care to the patients. OBJECTIVES The aim of the present study was exploring the perceived threat in adult...

To investigate the cognitive characteristics that affect the emotional and functional distress caused by tinnitus and to decide and test the model to explain their relations, 167 patients with tinnitus, who visited Samsung Medical Center, Seoul, Korea between March 2001 and May 2002 were recruited. To examine their features related to tinnitus, the following scales were administered; Tinnitus-r...

With the advancement of 3D line laser imaging technology (“3D technology”, hereafter for the sake of brevity), high-resolution 3D transverse profile data (“3D data”, hereafter for the sake of brevity), has gained widespread interest from researchers, industry and highway agencies and has been used for collecting pavement surface distresses. However, the study of data characteristics, e.g. data ...

Many agencies use the AASHTO Guide for Design of Pavement Structures to design their pavement systems. The limitation inherent in this method is the empirical nature of the decision process, which was derived from a road test conducted almost 45 years ago in Ottawa, Illinois. The newly released Mechanistic-Empirical Pavement Design Guide (MEPDG), based on NCHRP Study 1-37A, has adopted a mechan...

Using of software on many objects requires study of question of increase of reliability of such software. Each mistake can bring in software on such objects to serious consequences and even distresses. In addition conciseness of periods required for development, limitation does not often allow in human and financial resource to reach required parameters of software safety. So it is necessary to...

This paper describes a 3-D automated pavement distress data collection and analysis system based on NRC’s Biris sensor technology. The paper introduces the problem to be solved, the selected design criteria, and the adopted solution to monitor the quality of road surfaces. The system geometry for the acquisition of the threedimensional coordinates of pavement surface distresses is presented. Mu...
