The equation of Motion by Gibbs - Appell formulation has been used the least for deriving the dynamic equations of manipulator robots. So, in this paper a new systematic method for deriving the equation of motion of n - rigid robotic manipulators with revolute - prismatic joints (R - P - J) is considered. The equation of motion for this robotic system is obtained based on (G - A) formulation. All the mathematical operations are done by only 3×3 and 3×1 matrices. Also, all dynamic characteristics of a link are expressed in the same link local coordinate system. Based on the developed formulation, an algorithm is proposed that recursively and systematically derives the equation of motion. Finally, a computational simulation for a manipulator with three (R - P - J) is presented to show the ability of this algorithm in deriving and solving high degree of freedom of robotic system.

Aims: Head lice infestation is a common and significant health issue among students and in school settings. It is particularly more prevalent in children aged 5-13 years. This study aimed to investigate the determinants of preventive behaviors against pediculosis based on the theoretical framework of the health belief model among students in the urban areas of Heris County.
Instrument & Methods: This descriptive-analytical correlational study was conducted with 1,000 students in urban schools in Heris County, East Azerbaijan. Data were collected through a census of all fourth and fifth-grade students in elementary schools. The research instrument was a questionnaire designed based on the health belief model, which had been validated, and its reliability was confirmed in previous studies. After the students completed the questionnaires, the data were analyzed using SPSS 16 by ANOVA and multiple linear regression.
Findings: Fourth-grade students demonstrated higher awareness (p=0.027) compared to fifth-grade students. Perceived susceptibility (p=0.001) and perceived barriers (p=0.004) were significantly (p=0.0001) higher in individuals with no history of pediculosis infestation compared to those with a history of pediculosis infestation. Except for the perceived severity construct, all components of the health belief model had a significant correlation with preventive behaviors against pediculosis. Furthermore, awareness (p=0.0001), self-efficacy (p=0.0001), perceived barriers (p=0.0001), gender (p=0.0001), and maternal education (p=0.024) were identified as key predictors of these behaviors, and these parameters collectively accounted for 21.5% of the variance in behavior changes (R²=0.215).
Conclusion: Awareness, self-efficacy, and perceived barriers play a significant role in adopting preventive behaviors against pediculosis infestation.

The main purpose of this paper is to derive the inverse dynamic equation of motion of n-rigid robotic manipulator that mounted on a mobile platform, systematically. To avoid the Lagrange multipliers associated with the nonholonomic constraints the approach of Gibbs-Appell formulation in recursive form is adopted. For modeling the system completely and precisely the dynamic interactions between the manipulator and the mobile platform as well as both nonholonomic constraints associated with the no-slipping and the no-skidding conditions are also included. In order to reduce the computational complexity, all the mathematical operations are done by only 3×3 and 3×1 matrices. Also, all dynamic characteristics of a link are expressed in the same link local coordinate system. Finally, a computational simulation for a manipulator with five revolute joints that mounted on a mobile platform is presented to show the ability of this algorithm in generating the equation of motion of mobile robotic manipulators with high degree of freedom.

The main goal of this paper is to present a mathematical model for inverse dynamic equation of elastic robotic manipulator with revolute-prismatic joints. Due to the fact that there is no limitation on the number of mechanical arms, the proposed model must be extracted based on a systematic and automotive algorithm. Also according to the high computational complexity, the equations should be formed by a recursive formulation. Hence, a recursive and systematic methodology for deriving the equation of motion of elastic robotic arm with revolute-prismatic joints is presented. The inverse dynamic equations for this robotic system are obtained based on Gibbs-Applle formulation. All dynamic expressions of a link are expressed in the same link local coordinate system. Finally, in order to show the ability of this formulation in deriving and solving the equation of motion of such systems, a computational simulation for a flexible single robotic arm with revolute-prismatic joint is presented.

This paper presents a research into the progress of modeling of N-viscoelastic robotic manipulators. The governing equations of the system is obtained by using Gibbs-Appell (G-A) formulation and Assumed Mode Method (AMM). When the beam is short in length direction, shear deformation is a factor that may have substantial effects on the dynamics of the system. So, in modeling the assumption of Timoshenko Beam Theory (TBT) and its associated mode shapes has been considered. Although considering the effects of damping in continuous systems makes the formulations more complex, two important damping mechanisms, namely, Kelvin-Voigt damping as internal damping and the viscous air damping as external damping have been considered. Finally, to validate the proposed formulation a comparative assessment between the results achieved from experiment and simulation is presented in time domain.

This paper presents the investigation of general formulation and numerical solution of the dynamic load carrying capacity (DLCC) of flexible link manipulator. The proposed method is based on open loop optimal control problem. A two point boundary value problem (TPBVP) is provided, extracted from the Pontryagin's minimum principle. The indirect approach is employed to derive optimality conditions. The system’s dynamics equation of motion is obtained from Gibbs-Appell (G-A) formulation and assumed mode method (AMM). Elastic properties of the links are modeled according to the assumption of Timoshenko beam theory (TBT) and its associated mode shapes. As TBT is more accurate compared with the Euler-Bernoulli beam theory, it is exploited for mathematical modeling of flexible links. The main contribution of the paper is to calculate the maximum allowable load of a flexible link robot while an optimal trajectory is provided. Finally, the result of the simulation and experimental platform are compared for a two-link flexible arm to verify the introduced technique. The efficiency of the proposed method is illustrated by performing some simulation studies on the IUST flexible link manipulator. Simulation and experimental results confirm the validity of the claimed capability for controlling point-to-point motion of the proposed method and its application toward DLCC calculation.

Conventional lateral force resisting systems, dissipate seismic energy through plastic deformation in primary structural members that results in significant damage in buildings. In most cases, repair of these induced damages are impossible from the structural viewpoint, or have not economic justification. Recent research works are to localize the induced damage to specific elements (as fuse, dampers and etc.) without plasticization of primary load-carrying elements that ensure the stability of structure. In steel structures, the self-centering rocking braced system is an innovative type of seismic lateral force resisting systems that is developed with aim to minimize structural damages, residual drifts and enable repair or replace of damaged elements with minor expense after experiencing earthquakes. Steel braced frame with controlled rocking system consists of three primary components: (1) steel braced frame with rigid joints and no connections to base foundation at the column bases that is free to rock cyclically during excitation; (2) post tensioning cables which are connected to the frame top and foundation base in order to provide retreat back or self-centering capability of the system. Expressed mechanism plays an important role in restoration of quake-imposed displacement into its initial position; and (3) the replaceable energy dissipating elements that act as structural fuses to absorb seismic energy through undergoing of inelastic deformations and provide the required ductility of the system prior to instability or collapse. In this type of lateral force resisting systems, the post tensioned cables and the members of the braced frame are design to remain elastic during excitation and provide high stiffness, strength and global stability of the structure with minor local deformations. In this design concept, post tensioned strands are the key members known in providing self-centering capability of the system and occurrence of any plastic deformation in these elements endangers overall stability of system. Probable exceedance of seismic force may result in yield of post-tensioned cables and consequent elimination of restoring functionality of self-centering mechanism. In current research work, the steel material is replaced by carbon fiber reinforced plastic (CFRP) fabric in post tensioning strands, and the consequent effects of proposed substitution is investigated on the behavior of braced frame and linked structural components. The research was conducted on two steel braced frames with controlled rocking system equipped with steel and CFRP cables and the models are analyzed using nonlinear dynamic time history analysis (NLTHA) procedure. The frames are subjected to JMA-Kobe ground motion record, that is scaled to 69%, 100% and 120% intensity groups which corresponds to unit, 1.45 and 1.74 times of maximum considered earthquake (MCE) ground motion level. Extracted results show that using CFRP post tensioned cable instead of steel cables, can protect the system against instability even under 100% Kobe ground motion record scale and leads to a more reliable type of controlled rocking systems. This study also revealed that remaining the CFRP cable on elastic region not only controls the frame lateral displacement, also prevents early failure in fuses under severe earthquakes and ensures the seismic energy dissipating capability of the structure.

In this article, the dynamic equations of multiple flexible links robotic manipulators fabricated of functionally graded materials (FGM), whose properties vary continuously along the axial direction and also along the thickness, are examined. Gibbs-Appell methodology and Timoshenko Beam Theory according to the Assumed Mode Method are utilized to obtain the equations of motion and to model the flexible characteristics of links, respectively. Subsequently, the influence of power law index on the vibration response of a two-link functionally graded robotic manipulator is studied for two cases in which the mechanical properties of links vary once along the axial direction and again along the thickness direction of each link. By introducing a parameter called signal energy, it is shown that the power law index has a substantial effect on the vibrational behaviors of the mentioned system; and that by choosing a proper power law index, system vibrations can be reduced considerably in a passive way.

Pistachio is one of the most popular nuts in the world because of its taste and nutritional properties. Mostly, its consumed dry in harvest period. Major factors limiting for shelf life of pistachios are browning and water accumulation. In this study, the effects of citric acid (1, 1.5 and 2%) and ascorbic acid (15, 25 and 35 ppm) and two types of plastic packs (polyethylene and polystyrene) on storage life (days 0, 25 and 45), Ahmad aghaie pistachio was studied. According to panelists, the use of acid treatments for 25 day of storage was able to maintain the appearance and taste characteristics of pistachio and since then there was no significant difference between treatment and the control sample. Pistachios treated with 15 ppm ascorbic acid in polystyrene pack were more favorable in appearance and browning than polyethylene pack. The maximum of phenol was related to ascorbic acid treatments (15 ppm) in polyethylene pack. Anthocyanin and chlorophyll amount decreased during storage, but carotenoids first increased and then decreased. Pistachio pigments such as chlorophyll, anthocyanin and carotenoids were preserved in polyethylene packages than polystyrene. Citric acid treatment (1.5%) had the maximum percentage of fat. Overall, the polyethylene pack and ascorbic acid 15 and 25 ppm and citric acid 1.5% concentration maintained the qualitative and quantitative properties of pistachio.
