In this paper, the proposed CANTrack solution is described and its implementation is thoroughly explained. CANTrack is a sophisticated Computer Aided Design (CAD) tool that supports the entire development process for automotive networked systems. CANTrack differentiates itself from other competitive tools; by not only supporting planning, development, testing and finally starting-up; but also incorporating the unique features of CAN bus security enhancement and tool customization upon customer needs. The Controller Area Network (CAN) bus security feature is implemented using an intuitive algorithm that encrypts the 8-byte payload data using a symmetric key that is being dynamically changed using synchronized key generators across all nodes. This algorithm makes the encrypted message unique at any instance of time to avoid replay attacks. The algorithm is tested thoroughly on an experimental setup using Vector Canoe; with the results of two use cases presented.

Swirling flow in gas turbine combustors is a very common tradition in aerospace and/or industrial applications. This is because, swirl flows help to anchor flames, and cause better air-fuel mixing which enhance combustion efficiency and reduce harmful emissions. As a result, it is of a high interest to be able to predict the behavior of swirling turbulent flows in order to better design combustors. Therefore, this study performs a numerical simulation of an isothermal swirling turbulent flow of air at room temperature in a combustor model, created using a 0.4 free vortex swirler. The simulation was performed via a computational fluid dynamics (CFD) software. Results of three different turbulence models were compared against experimental measurements found in the open literature for the same swirler and same all flow specifications upstream of the swirler. Consequently, it was found that the k-ε turbulence model best predicts the actual swirl flow behavior and exhibits superior prediction quality compared to the other tested models.

The aim of this paper is to develop an improved maintenance strategy for a manufacturing system composed by several identical parallel leased machines using Center-of-Gravity approach. We present at first the optimal production plan of the studied system found by minimizing its total cost of leasing, setup, inventory and work times. Then, according to the obtained production plan, we determine the maintenance strategy for each machine. Once found, these plans are used to find the configuration of the new improved maintenance strategy by combining numerous maintenance actions in a single and unique one according to Center-of-Gravity approach.

This paper shows a detailed modeling process for a hexacopter, taking as a control variables, the force and torques actuating on the vehicle. It also shows the hexacopter equilibrium manifold, with some numerical results that evidence the symmetry along the x and y axis. Finally, a nonlinear optimal control problem is formulated in order to see the hexacopter maneuverability capabilities, showing clearly the difficulty of motion on the x and y axis, due to the lack of actuators on those axis. Some numerical results of trajectories that the hexacopter is able to follow are shown.

Synchronous Sine Triangle Pulse Width Modulated (SPWM) inverter operating an induction motor ensures lower harmonic losses and better drive system performance. Conventionally, this synchronism is realized by linear frequency controller which multiplies the fundamental frequency with a suitable number to attain the value of carrier frequency, thus linearly increasing the carrier frequency as the motor speed increases.This work is based on the offline analysis of motor current data and selects the optimal carrier frequency for various operating speeds. This optimal carrier frequencies data results into a second degree polynomial which is then incorporated in the drive system controller. The proposed polynomial dynamically adjusts the carrier frequency with the changing motor speed which results in lower total harmonic distortion and lesser overall drive system losses as compared to the linear frequency controller. This work also suggests a novel strategy for switching the inverter mode of operation from sine triangle to square wave when the machine speed reaches above the base speed. The proposed methodology for mode switching is realized by adjusting the carrier frequency of the triangular waveform to zero which makes this transition seamless and does not cause any torque ripples. The so designed drive system with synchronous SPWM and mode switching from SPWM to square wave and vice versa is simulated and its performance is experimentally validated on a 175 Watt prototype induction machine.

The use of manipulator on quadrotor is highly restricted due to expected arising instability problems. This paper investigates a new approach in designing manipulators mounted on quadrotors that ensures maintaining maximum MM-UAV stability. In this approach, an algorithm is used to predict the payload's mass variation that results from catching or releasing objects. The ability of the manipulator to preserve the quadrotor stability is verified by simulation. The results of the study reveal that the manipulator can move while ensuring the stability of the quadrotor. This approach ensures that the resulting shift in the quadrotor center of gravity (CoG) does not exceed 0.5 mm at a specific payload mass in the steady state. The results also show that the reaction torque on the quadrotor which is caused by the manipulator's movement is approximately zero in the steady state.

With the ever growing demand of prosthetics due to increased amputations, there is a need for development of an economic prosthetic foot which has similar functional integrity to that of a higher end model. The main need of this arises in developing countries where people are not able to afford such prosthetics. The primary objective of this study is the development of an Energy Storage And Return foot that is economically viable. In this Work, finite element simulations were conducted for a new Acrylonitrile Butadiene Styrene (ABS) material. The proposed ABS foot showed identical results to that of a commercial Carbon Fiber foot. Moreover, the proposed foot is cheaper, has a less weight, and appropriately stiff.

Data centers are experiencing tremendous growth in the number of servers and networking devices with an increase in traffic to cloud infrastructures. Data center network (DCN) topology plays an important role in providing acceptable level of performance to cloud applications. This paper presents the results of a simulation studies comparing the performance of several well-known DCN topologies under the same simulation and inter-network traffic workload environments.

A reasonable clamping form can effectively reduce the distortion and defect in wire and arc additive manufacturing. In this paper, a three-dimensional finite element model with verified weld-bead profile and heat source model is established. Using the Simufact.welding finite element analysis software, four typical clamping forms are compared in total distortion and residual stress distribution. The results demonstrate that the edge clamping form has the better performance than the corner clamping form. In edge clamping form, the transversal clamping plays the dominant role than the longitudinal clamping in guaranteeing the dimensional precision. Basing on the analysis of residual stress distribution, the clamping form with only the transversal clamping can obtain the least residual stress distribution.
