Due to their various promising potential applications in the field of structural control, semi-active control of Magneto-Rheological (MR) dampers has been enjoying significant research focus for more than two decades. In this paper, a new direct voltage control algorithm for the MR damper is proposed to enhance the seismic response of civil structures. The MR dampers are represented using a modified Bouc-Wen model. A mathematical model representing a 3-story frame building with MR dampers at the ground floor in a chevron brace configuration, is used for the simulations. The proposed control law shows a high ability of attenuating structural response (floor accelerations and displacements). Simulations of the structural response under to the El Centro earthquake ground motion, are used to demonstrate the efficiency of the proposed control algorithm. The proposed control algorithm performance compares very well against other control algorithms available in the literature given its inherent relative simplicity.

According to IRENA the number of countries adopted a target to ratify the renewable energy on their electricity grid went from 43 countries to 164 over a course of 10 years only. These targets which will increase renewable energy share on the electricity grid, implies the use of Distributed Generation (DG) like roof-top PV panels or the construction of small scale dispersed renewable-based power plant like wind or PV farms. The aim of this paper is to study the impacts of high PV and wind penetration into the grid. To address these impacts, a comprehensive study performed on a test system provided by IEEE to model the integration of DG plants into a 33kV distribution network using Etap software. Three levels of integration were modeled to reflect the impact of DG plants penetration on gradual basis, 6 scenarios have been assumed and two types of tests have been carried out to investigate their impact on the grid; fault level and frequency transient stability were performed individually at each level of penetration. Additionally, in order to examine the grid performance during extreme weather conditions, several events have been assumed to model the intermittent properties of renewable energy generation. The obtained results showed very good performance of the grid for penetration less than 30% while higher level of PV and wind penetration requires further attention and modification on the grid side.

The sub-frame which insulates the vehicle chassis from the high frequency excitation of the engine has a great influence on vehicle performance. Currently, the research on the influence of sub-frame on vehicle performance mainly aims at the vehicle vibration attenuation and noise reduction performance, and there is a lack of research on vehicle handling stability and the accurate description of the high frequency excitation force of the engine. This paper is characterized by a more accurate description of the role of the engine in the sub-frame excitation force, as well as a more comprehensive study of the impact of the sub-frame on vehicle performance. Firstly, the dynamic engine model with high frequency excitation changing with cylinder pressure is built, and the flexible sub-frame model is built by modal method. Then they are integrated into the vehicle simulation model. The simulation is conducted in the conditions of acceleration resonance, ride comfort and handling stability. Through the simulation this paper analyses the influence of the different key design parameters (mass, structure stiffness, mounting stiffness and damping coefficient) of sub-frame on the vibration isolation performance of sub-frame to vehicle, vehicle ride comfort and handling stability. This research may improve our understanding of the impact of the sub-frame and its mount system on the vehicle performance under the high frequency excitation of the engine, so as to provide an effective reference for their design.

Sensor fusion represents a robust approach to ecologically valid obstacle identification in building a comprehensive electronic travel aid (ETA) for the blind and visually impaired. A stereoscopic camera system and an infrared sensor with 16 independent elements is proposed to be combined with a multi-scale convolutional neural network for this fusion framework. While object detection and identification can be combined with depth information from a stereo camera system, our experiments demonstrate that depth information may be inconsistent given material surfaces of specific potential collision hazards. This inconsistency can be easily remedied by supplementation with a more reliable depth signal from an alternate sensing modality. The sensing redundancy in this multi-modal strategy, as deployed in this platform, may enhance the situational awareness of a visually impaired end user, permitting more efficient and safer obstacle negotiation.

Continuous Passive Motion (CPM) has been totally accepted as a physical therapy in the recent decades. There have been a number of CPM systems from the most complicated mechatronic systems to the least, developed for this purpose. Despite all improvements in manufacturing such machines, an optimum design needing an acceptably low power for efficient functioning has not yet been targeted. The aim of this paper is to kinematically synthesize a linkage-based mechanism for knee CPM with three-accuracy-point approach. An optimization problem is then defined to find the mechanism with the least amount of power generated by the driver joint and force generated at knee joint.

A quadrotors is a type of Unmanned Aerial Vehicles (UAV) systems that attract the researchers in the control field since it's a highly nonlinear, underactuated system. In this paper, a non-linear dynamic model based on quaternions is developed. Differential flatness is an approach that enables the optimization to occur within the output space and therefore simplifies the problem of the trajectory tracking. This work aim to combine both methods in order to create a differential flatness-quaternion based approach that enables the quadrotors to follow a desired optimal path and avoid any singularities that can occur. The trajectory tracking is assured by a double loop control structure based on the LQR controller.

This paper seeks to jointly optimize the operational decisions associated with raw material procurement, production lot sizing as well as finished product dispatching for a two layer supply chain comprised of a single-vendor and a single-buyer. A more general raw material replenishment schedule is considered wherein multiple raw material shipments may take place within one cycle, referred to as multi-to-one (MTO) policy, or alternatively a single shipment that covers the production for multiple cycles, referred to as one-to-multi (OTM) policy, may rather be adopted depending on whichever is optimal. The aforementioned decisions are simultaneously optimized through mathematical models that embrace the integer multiplier of the cycle time policy. A numerical example that illustrates the performance of the developed models is also presented.

From the statistical point of view the solution is based on the maximum-likelihood method. The paper presents analytical equations for likelihood coefficients and the structural scheme of their forming in the solution of radar signal recognition. To analyze the efficiency of the proposed algorithms are found boundary equations for probability calculating of correct signals with the usage of Chernoff-Kailath ratios.

Wheelchairs equipped with fixed positioned robotic arms is proposed to help paralyzed people. However, such a configuration makes it hard for the users to orient the wheel chair such that the task in need lies within the arm workspace. In this work a robotic arm that slides over a track mounted over a wheelchair is proposed to attain much wider workspace, at no extra complexity of arm design. Proposed design also reliefs the need to orient the wheelchair for extra user comfort. This work represents the Kinematic equations, Dh-parameters and dynamic modeling & simulation of an RRR robotic arm moving along a path built onto a wheelchair including the 3D workspace of the system. Preliminary results show robotic arm can achieve a very dexterous workspace at no extra cost in terms of arm torques yet offering a great comfort for wheelchair users.
