This paper focuses on ontology construction as a foundation for knowledge representation. We present here the processes of knowledge acquisition, analysis, and representation using a conceptual modeling tool, the Inferential Modeling Technique (IMT), as a basis for ontology construction. To illustrate the knowledge modeling process, we apply IMT for knowledge analysis in the domain of petroleum...

background: safety programs are a core part of safety management in workplaces that can reduce incidents and injuries. the aim of this study was to investigate the influence of safety training observation program (stop) technique as a behavior modification program on safety climate in a construction company . methods: this cross-sectional study was carried out on workers of the petrochemical co...

While in the historic urban fabric of Iran's cities, there are numerous traditional buildings that have stood up for more than one hundred years, today's buildings, in spite of advanced construction technologies, are not comparable with those traditional ones in terms of resiliency and durability. The sustainable vernacular strategies in design and construction of these traditional houses are t...

The construction process control of large-scale projects is one of the difficulties and the keys in the owner’s project management. Based on generalization process index, this paper proposes an approach to construction project process control. The paper elaborates on the concept and calculation of generalization process index, which, on analysis, possesses Markov property. Monthly generalizatio...

Having been very much impressed by the results obtained with use of a segment of the sigmoid colon as a partial substitute for the urinary bladder (colo-cystoplasty), we decided to perform total substitution of the cancerous bladder with an isolated segment of the sigmoid colon anastomosed to the urethra, thus obtaining a functional artificial bladder from which the patient would void through t...

Research paper Allen studied hundreds of construction projects and developed an accu-rate, practically useful model of their labor profiles. We combine Al-len’s labor profile with standard Earned Value Management (EVM) techniques and derive a simple, practical formula that estimates the fi-nal schedule from early project data. The schedule estimation formula is exact; it requires no approximati...

Since the first frame-mounted fascia lata heart valves were used clinically (Ionescu and Ross, 1969), over 260 tissue valves made of autologous or homologous fascia lata or of heterologous pericardium have been inserted at this institution in the mitral, aortic, and tricuspid positions. Encouraged by our results, especially with aortic valve replacement, over more than four and a half years (Io...

A two-staged technique for construction of experimental aneurysms in swine is described. The jugular vein is initially anastomosed to the carotid artery. Spontaneous hypertrophy of the vein is modeled by placing restraining sutures to create a fusiform aneurysm. Subsequent endovascular closure of this aneurysm leaves a sidewall aneurysm pouch. Staging allows maturation of the anastomosis, and t...

All the real world parameters such as temperature, pressure etc., are analog in nature, In order to control these physical parameters using computers, which are digital in nature, high speed signal processing board is used. This mainly consists of devices such as analog to digital converter, digital to analog converters and timer which perform the interfacing function between analog and digital...
