Currently there is one of the prevalent diseases of 21st century is liver disorders annually killing so many people’s round the worlds. A range of therapies have been provided by researcher to evaluate results. Early diagnosis is of considerable amount of significance in treating the disease. Diagnosis is of the physician skills conducting based on their knowledge’s and experience yet an error ...

In this paper we analyze two methods of artificial intelligence: the Bayesian filter and the Fuzzy Logic engine. In order to do this we present each method and compare them. The mentioned methods have similar backgrounds but from epistemological point of view they are different. The paper ends with three case studies: the first about a Fuzzy Logic engine which is integrated into a Bayesian filt...

This paper reviews motivations for introducing fuzzy sets and fuzzy logic to knowledge representation in artificial intelligence. First we consider some areas of successful application of conventional approaches to system analysis. We then discuss limitations of these approaches and the reasons behind these limitations. We introduce different levels of representation for complex systems and dis...

Chronic exposure to environmental ultraviolet radiation (UVR) plays a key role both in photocarcinogenesis and induction of accelerated skin ageing. Sailors commonly experience a significant number of cutaneous problems, related to the exposure to environmental factors due to their working conditions. Among these factors, sun exposure is able to determine both acute and chronic skin damage, mos...

freshwater resources represent around 3% of all water on earth, and less than 1% of that is available. consideringcurrent conditions, as well as future predictions of need, freshwater resources cannot meet human needs. thus,sweetening of the brackish water can be performed to provide freshwater for human use. solar energy, because ofiran's climatic conditions, may be used for sweetening the bra...

In this study, an artificial neural network (ANN) based model for prediction of solar energy potential in Kuala Lumpur, Malaysia was developed. Standard multilayered, feed-forward, back-propagation neural networks were designed using Microsoft Excel (MS Excel). The meteorological data were acquired from Malaysia Meteorological Department. The data was consists of meteorological data from one st...

Introduction: Normal exposure to sunlight results in the production of vitamin D in human body, which happens because of the interaction between ultraviolet radiation and cholesterol in skin. Exposure to sunlight is responsible for 90 percent of vitamin D needed for the body. Studies show that Iran is a country with high percentage of lack of vitamin D (83 percent). Based on pr...

The representation of knowledge is one of the fundamental research areas in the realm of artificial intelligence. One approach to this subject has been provided by the Arden Syntax for Medical Logic Systems. At present, this syntax includes typical procedural programming language elements used to define crisp decision logic. However, medical knowledge usually contains linguistic uncertainty tha...

The research objective was to gather and collate data that will enable dermatologists to quantify exposure to solar radiation so that they can give accurate advice to patients using heliotherapy, thereby minimising harm from sun exposure. Other patients can also be advised regarding ultraviolet index (UVI) and sun safety. The concept of minimal erythema dose per hour (MED/h) may be useful in fu...

It has been a practice in control system design to provide certain means of control in any control system by using different techniques such as adding compensators like PI, PD, and PID, with the incorporation of machine intelligence techniques such as fuzzy logic, artificial neural networks, and evolutionary computation. This paper presents a design approach in the development of compensators f...
