Abstract :

Infiltration is a complex physical process in timeand space, which isdifficult to characterize with precision under the intrinsicheterogeneous and dynamic soil conditions. The precise determination of the water infiltration in the soil helps to minimize the risks of degradation, especially with the processes of surface runof and flood. Dashte-Abbas is one of the most talented agricultural areas of the Ilam province and Iran country. measurement and classification of soil infiltration is essential to better manage water resources and the prevention of desertification in the Dashte-Abbas plain. Measurement of soil infiltration is time and cost consuming and but many models have been developed for infiltration estimate, which prevents of a lot of time and high costs consuming. Kostiakov is one of the models that is being used widely to estimate soil infiltration, which as the most widely used model in the planing of soil and water. The main objectives of this study were: to; 1) validate the Kostiakov model estimates with the measured cumulative infiltration and 2) to determine the coefficients of Kostiakov model. For this purpose, soil infiltration measured using the double-ring infiltrometer in 37 stations with 3 repetitions. Using the data obtained, Kostiakov model coefficients were determined. Mean values of a and c coefficients were 0.4275 and 0.7542, respectively. Results showed that the range of variation of coefficient of c was large, which demonstrated considerable spatial variability in the study area. The normalized root mean square error (NRMSE) indicates the total difference between the measured and modeled (estimated) values was NRMSE=0.15, and performance efficiency was EF= 0.74. Thus, it confirms that the Kostiakov model accurately estimates the cumulative infiltration in the Dashte-Abbas plain in southwestern Iran.

Abstract :

Wind energy is no doubt the most competitive low carbon energy. Many traditional power plants have also set up wind parks. Due to the randomness of the wind power output, power plant faces the problem of how to make a dispatch plan for its power generation units when the load demands is confirmed from the electric power market in advance. This paper presents a green revenue management model for power plants with wind parks under an uncertain power out put condition. Generation cost, spinning reserve cost and external cost (emission) are all taken into account. The model has a stochastic programming formulation designed to capture the randomness of wind power output. A novel approach of robust optimization and ant colony algorithm are applied to solve the problem on a scenario-basis. Decision-makers’ risk aversion is considered in the objective function. Mean absolute value is used to measure risk of deviation of revenue from its expected value. As the external cost of carbon emission and the randomness of the wind power output are considered in the model, the result presents a robust dispatch plan for the power plant, which can achieve good benefit.

Abstract :

The average annual precipitation in Iran is less than one-third of the world average. Also, distribution of rainfall on temporal and spatial scales is poor. For combat water shortage, rain water harvesting (RWH) is the best option in the arid regions like Iran. The main purpose of this study was site selection of water harvesting systems. At the first stage, factors influencing site selection of RWH systems and rainwater storage were determined. The four main criteria including physiographic, rainfall, vegetation and soil factors were selected. At the second stage, standardized and weighted factors based on analysis hierarchy process (AHP) and finally, each layer was multiplied by its weight. Results showed that the most important factor for site selecion of RWH is slope factor. But the importance of elevation classes factor was greater than the slope factor in the pitting method in comparison with farrowing method.

Abstract :

Information and Communication Technology (ICT) has made significant impact on healthcare industry across the globe. Its adoption and use, which result into e-healthcare, has transformed the way healthcare services are delivered. Hospitals in Nigeria are adopting e-healthcare in order to improve transparency, efficiency and effectiveness in service delivery. This paper attempts to present a developed Patient Management Information Systems (PMIS) using a case study of General (State) Hospital, Ijebu-Ode, Ogun State, Nigeria. The main objective is to design a web-based medical application capable of eliminating paper-based healthcare system where patient’s health information are collected every time a patient visits the healthcare centre thereby allowing e-healthcare physicians to collect Personal Identifiable Information (PII) only once and frequently update its related medical records. The application is based on a browser/server framework. PMIS supports adaptive as well as standard recording of patient’s data, along with automatic appointment notification and record keeping using the WAMP server as a delivery channel.

Abstract :

Under linear demand conditions, assuming there is a two-echelon supply chain carbon emission reduction system composed of a supplier and a retailer, we introduce the Nash Bargaining fair Solution into the model, engage in case studies to examine the supplier's optimal wholesale price and his optimal carbon emission reduction as well as the retailer's optimal retail price. For that reason, we consider three different cases such as the retailer having fairness preference, the supplier having the fairness preference and both of them enjoying fairness preference at the same time. The study found out that both supplier’s wholesale price and retailer’s sales price are affected either by their own fairness preference or by that of the other party, more important in the game the supplier will not actively take the initiative to reduce carbon emissions since the volume will progressively decrease as a supply chain entity’s fairness preference degree increases.

Abstract :

The appearance of lipid plaques on the walls of blood vessels is called atherosclerosis. According to the World Health Organization’s statistics, atherosclerosis can affect blood vessels, regardless of age and occupation of the person. In spite of a number of studies, devoted to the investigation of this disease, the exact factors and their influence on atherosclerotic plaque formation and evolution have not yet been determined. Presented investigation examines the influence of mechanical factors on the evolution of atherosclerosis. In this paper a time-dependent coupled problem of the atherosclerotic plaque formation and evolution in the coronary artery has been presented. Penetration of low-density lipoproteins (LDL) into internal layers of the blood vessel, diffusion of macrophages and deformation of the vessel wall with endothelial defects have been considered. The mathematical model of the arterial wall has been implemented using the finite element (FE) package Comsol Multiphysics. The solution has been obtained by means of the following working modes: Convection/Diffusion (for the LDL penetration process), Diffusion (for the LDL modified by macrophages, or foam cells), and Moving Mesh (for visualizing the wall deformation).

Abstract :

Every day an enormous amount of data is retrieved and transmitted on the Internet. Internet gives rise to have the relevant information more quickly. Most of the users or researchers required the image data from the available image database. For the retrieval of concern image data from the huge database is tedious task in terms of the storage and retrieval time. So the image data storage and retrieval time are the perplexities of any database systems. To overcome these perplexities, the image retrieval systems are exist and proposed in the literature. The majority of image retrieval systems focus mainly on color distribution. The most popular and well-developed techniques are based on color or brightness histograms. Many problem domains used the concept of content based image retrieval. Attribute based approaches are used to retrieve the images from image database. But feature based approaches are generally used in Content-based image retrieval systems. The important common features of the image: color, texture, shape, boundary, intensity levels, frequency domain feature, spatial domain feature are used as the basis to form the feature database in content based image retrieval.

Abstract :

A movement during measurements can generate motion artifacts in photoplethysmography(PPG) signals. The motion artifacts reflect some information of tester’s motion. If we can extract the relevant information from these interferences, it probable will be a new information collection method for portable physiological monitor. This paper first analyzes the relationship between the motion artifact and the PPG signals form the Beer-Lambert law. Then, compare the influence of PPG signals by different direction of movement. Finally, extract the information of motion through the reconstruction of wavelet transforms modulus maxima. Through compares the extracted signal and the real motional signals collected by accelerometer (ACC), two signals have certain relativity. The extracted signal can basically reflect the tester’s movement. It will be a new way of community and athletes medical care.
