Study the effect of the painted look in the works of illustration of iranian painter artists

Modern painting in Iran seems dynamic and energetic at first glance; however, some believe that it’s alien to Iranian national Identity and some others believe it has led to identity crisis. Painting and portraiture has undergone considerable changes. The importance of these changes, characteristics and functions, lead to our research goal. Research goal: to study the effects of artistic view in portraiture works of for Iranian painters: Ali Akbar Sadeghi, Mohammad Ali Bani Asadi, Karim Nasr and Farshid shafiei. Research method: The method used in this study is descriptive-analytic. Collecting data: The way to collect data is documentary and field research. Findings: Findings show that there is no significant difference between these two arts in many artistic works of modern painters and sometimes they overlap. Moreover, considering national Identity, painters have tried to modernize painting by the use of modern art methods. They have combined traditional art factors with western modern painting experience, added by national belief to create a kind of harmony and balance between these two arts

Optimal Usage of Robot Manipulators

Robot-based automation has gained increasing deployment in industry. Typical application examples of industrial robots are material handling, machine tending, arc welding, spot welding, cutting, painting, and gluing. A robot task normally consists of a sequence of the robot tool center point (TCP) movements. The time duration during which the sequence of the TCP movements is completed is referred to as cycle time. Minimizing cycle time implies increasing the productivity, improving machine utilization, and thus making automationaffordable in applications for which throughput and cost effectiveness is of major concern.Considering the high number of task runs within a specific time span, for instance one year, the importance of reducing cycle time in a small amount such as a few percent will be more understandable.Robot manipulators can be expected to achieve a variety of optimum objectives. While the cycle time optimization is among the areas which have probably received the most attention so far, the other application aspects such as energy efficiency, lifetime of the manipulator, and even the environment aspect have also gained increasing focus. Also, in recent era virtual product development technology has been inevitably and enormously deployed toward achieving optimal solutions. For example, off-line programming of robotic workcells has become a valuable means for work-cell designers to investigate the manipulator’s workspace to achieve optimality in cycle time, energy consumption and manipulator lifetime.This chapter is devoted to introduce new approaches for optimal usage of robots. Section 2 is dedicated to the approaches resulted from translational and rotational repositioning of a robot path in its workspace based on response surface method to achieve optimal cycle time.Section 3 covers another proposed approach that uses a multi-objective optimization methodology, in which the position of task and the settings of drive-train components of a robot manipulator are optimized simultaneously to understand the trade-off among cycletime, lifetime of critical drive-train components, and energy efficiency. In both section 2 and 3, results of different case studies comprising several industrial robots performing different tasks are presented to evaluate the developed methodologies and algorithms. The chapter is concluded with evaluation of the current results and an outlook on future research topics on optimal usage of robot manipulators

Interaction between motor vehicles and bicycles at two-lane roundabouts: a driving volatility-based analysis

Drivers' instantaneous decisions regarding speed and acceleration/deceleration, as well as the time rate of acceleration change (jerk) can result in a volatility driving behaviour with significant impact on cyclist safety. The contribution of this article is the assessment of driving volatility in motor vehicle (MV)-bicycle interactions at two-lane roundabouts. Traffic flow and bicycle GPS data were collected from two two-lane roundabouts. Then, traffic, emissions and safety models were used to evaluate volatility impacts on safety, pollutant emissions and traffic performance. The findings showed jerk have an impact on driving volatility between MVs and bicycles, regardless of roundabout design with higher amplitude of variation for MVs. However, MVs had higher acceleration-deceleration variation than bicycles.publishe

Method for optimising the performance of a robot

A method for optimizing performance of a robot. At least one experiment is designed including at least two tests. Each test differs from at least one other test in the experiment regarding the location of the task in relation to the robot. The boundaries that are allowable for location of a task are calculated/determined. The effect on optimality for at least one test in the experiment is calculated/determined. The experimental data is fit to an algorithm. The optimal location of the task is calculated/determine

Investigation Stability of Upper Limb Function in Handballers with Glenohumeral Internal Rotation Deficit

Objective: Glenohumeral Internal Rotation Deficit is one of the important risk factors in throwing athletes that can cause adverse effects on glenohumeral joint biomechanics during throwing activity and overhead activity. Methods: In this descriptive study, 30 male student Hanballers (age=18 to 25 years) were categorized into healthy (n=15) and Glenohumeral Internal Rotation Deficit (n=15) groups. Upper quarter y balance test (YBT-UQ) was used for measuring functional instability of dominant shoulder. MANOVA test was run for comparing the performances of the two groups.  Results: In all directions, the stability of the shoulder in Hanballer with Glenohumeral Internal Rotation Deficit was significantly lower than that in the healthy group. Conclusion: Based on the results of this study, functional stability of the unstable shoulder of Hanballers with Glenohumeral Internal Rotation Deficit is lower than the functional stability of the healthy subjects; therefore, we suggest that the upper extremity stabilization exercises, specially the closed kinetic chain exercises be added to the shoulder rehabilitation programs
