Dust storms are increasingly threatening the forest ecosystem in Western Iran. Due to its coverage of vast area of Zagros forest, the Quercus brantii is at the front line of the attack. Most tree deaths in this forest are from this species. This study aims to investigate the effect of simulated dust on wood development and leaf stomata from seedlings of Persian oak. The oak seedlings were...

Ultrasound has been widely employed in food industry, while some of its working parameters are usually neglected to be described in its application, which caused the difficulty of reproducing and comparing the results obtained by different groups. So it is definitely not sufficient to simply state the ultrasound conditions such as ultrasound power, frequency and t...

Catamaran added V-like center bow (INCAT) is investigated as a wave-piercing vessel to decrease vertical acceleration and diminish slam events during sea-keeping operation. The catamaran and the vessel bow were modeled and the vertical acceleration of model was validated with experimenal test. The geometry of V-like center-bow such as slope of center bow and elevation from demi-hulls was optimi...

A self-organizing cooperation strategy for multiple unmanned surface vessels (USVs) to pursue intelligent evaders in the case of a dynamic obstacle vessel is proposed. Firstly, cooperative hunting proposed form an Apollonius circle. According escape strategies under different encirclement states, pursuers are divided into pursuit group and ambush group. The drives area completes together with I...

Knowing the activity of fishing vessels accurately and in real time means a leap quality management activity. This paper presents development new monitoring integral system (FAMIS) that can complement overcome limitations current vessel systems (VMS). FAMIS is developed on basis low-cost mobile device with GPS sensors, accelerometer, gyroscope magnetic field integrates different statistical met...

Background: The interaction between the blood and the vessel wall is of great clinical interest in studying cardiovascular diseases, the major causes of death in developed countries.Objective: To understand the effects of incorporating fluid-structure interaction into the simulation of blood flow through an anatomically realistic model of abdominal aorta and renal arteries reconstructed from CT...

Automatic vessel collision-avoidance systems have been studied in the fields of artificial intelligence and navigation for decades. And to facilitate automatic collision-avoidance decision-making in two-vessel-encounter situation, several expert and fuzzy expert systems have been developed. However, none of them can negotiate with each other as seafarers usually do when they intend to make a ha...

The heart is a muscular organ which pumps blood through blood vessels to different organs of the body. It is the most significant and vital organ in the human body. Without this organ, life is unimaginable. Doctors and scientists have been trying for a long time to create something similar or equivalent to the heart. The purpose is to develop a temporary machine or pump for a person who has a d...
