In this paper, we study the impact of carbon tax regulation on a two-stage supply chain operating under vendor managed consignment inventory (VMCI) partnership. We formulate simple models for the VMCI-type supply chain to determine the vendor's production lot size and the quantity to be shipped to the buyer that minimize the sum of the system-wide operational costs and carbon tax penalty. We present some structural properties for the optimal operating policies and show numerically that significant cost savings and carbon reduction can be achieved by adjusting the production and shipping quantities.

Regenerative braking technology is crucial for electric vehicle applications. Where, the motor is used as a generator to charge the vehicle's battery. However, the regenerated energy is not fully returned to the battery. Some power losses are experienced in between such as losses in the motor's armature and switching losses. The motor drive system described in this paper has an energy storage system comprised of a supercapacitor module and a lithium ion battery connected through a DC/DC converter to a dc motor. This allows efficient, high power transfer under regenerative braking and acceleration. Managing the power flow through the DC/DC converter and therefore the supercapacitor voltage is a key control parameter that affects the efficiency of the overall system.

Various local optimization techniques such as Interior Point Algorithm have been widely used to optimize the parameters of models representing biodynamic responses to vibration. The quality of the obtained solutions depends on the initial guesses. This paper presents a comparison between the performance of Particle Swarm Optimization and Genetic Algorithm in optimizing the parameters of a human body model, where these techniques do not require initial guesses. The model represents the vertical apparent mass and the fore-and-aft cross-axis apparent mass of the seated human body during vertical excitation. With both optimization methods, the model provided close fits to the moduli and phases for both median data and the responses of 12 individual subjects. However, it was noted that using PSO provided a better solution with less mean error than GA and a faster solution in most of the cases.

In the present paper, we present a new research bridge between two of the current hottest research branches in electrical engineering devices namely; CMOS imaging and Photovoltaics (PV). We start by showing the similarity between core areas of interest in each one namely the device, i.e. the photodiode and the difference between the two research areas. We conclude with an equation that depicts the central contribution of this paper demonstrating that any improvement at the device level made in CMOS imaging technology will inevitably and positively impact PV and visa-versa. Particularly, the suggested intelligent (bio-mimicked) photo-sensors can boost the solar energy conversion of their PV counterparts. This might not be possible in certain cases where fabrication technologies do not allow that and for that matter a non-disruptive change in the fabrication processes are necessary to take advantage of the new devices advancements. Finally, we present a futuristic solution based on the above pivotal idea opening a door for novel applications especially in battery-less biomedicals and wearables.

The main purpose of the present paper is to study free vibration of nonclassical micro plates with piezoelectric layers. To this end, the plate is modeled according to Kirchhoff's plate theory. Piezoelectric layers are modeled according to linear piezoelectricity theory and due to the small thickness, the electric field is assumed to be constant in these layers. The strain energy of the system is obtained using modified couple stress theory (MCST) and the governing equation of motion is derived using Hamilton's principle. The finite element model is used to solve the obtained equations and effects of piezoelectric layers and material length parameter scale on the natural frequency of the system are studied.

Studying gaze behavior (where someone looks) is an emerging area of research particularly in the domain of behavioral psychology. Gaze behavior can, for instance, indicate the amount of attention paid in certain tasks and whether the performance is natural or not. Also, it can indicate the level of competence and experience of the user. Therefore, it has the potential to be used as an evaluative tool in upper limb prosthetic field. In order to obtain informative results from gaze data, the visual scene need to be divided into areas of interests (AOIs) and the time of gaze fixation (eye fixation) has to be calculated. This process is usually completed manually by a rater, who goes through the gaze trial frame by frame, to report at which AOI the gaze is fixated at each frame. Therefore, this process is extremely tedious and is highly subjective, and thus prone to unsystematic error. The aim of this paper is to report the development of an automated algorithm which used to analyze gaze data and obtain an initial indication of its validity and reliability.

The performance of the systems which based on wireless signals such as localization system relies mostly on the propagation model. Radio signals can be mainly difficult to model because the channel varies significantly with the environment such as indoors. This paper studies two popular propagation models for indoor environments. Practically, these models do not estimate the radio signal fading properly. For that, we proposed a neuro-fuzzy based model as a propagation model which simulates the received signal strength for indoor environments. Compared with the empirical measurements, the proposed model shows higher accuracy in prediction of received signals than other existing channel models.

SELective Buried OXide MOSFET (SELBOX) structure reduces the self-heating and kink effect challenges linked with the Silicon on Insulator (SOI) MOSFET. The SELBOX structure also dissipates less static power than the BULK MOSFET while maintaining a high operating speed. In this paper, we present a model that describes the reduction in static power dissipation. SELBOX, SOI and BULK MODFET devices are designed and simulated with Silvaco TCAD tools. Simulation results are also presented and compared with the model results.

This paper develops a mathematical model of an inverted wheeled robot and uses it to simulate and animate the robot dynamics. The robot is modeled as a three-body system consisting of a pendulum and two wheels where the Newtonian mechanics is employed to derive the dynamical equations. The proposed model, in its current configuration, is designed to simulate and animate the controlled robot for forming a virtual controller-testing setup. The open-loop system is simulated by solving the nonlinear dynamic equations recursively within an animation loop by using the Runge-Kutta 4 (RK4) method. The nonlinear model is linearized for designing a PID controller to stabilize the closed-loop system of the robot. The animation process is conducted by creating two graphical objects that resemble the wheel and pendulum in a graphical user interface window. The keyboard arrows are used to interactively input the horizontal motion of the robot cart to the animation process where there is also an option to switch the controller off. Simulation results are provided for both the open-loop and closed-loop cases to illustrate the effectiveness of the results.

The Steel Plate Shear Walls (SPSW) system is one of many Lateral Force Resisting Systems (LFRS) added to the design codes over recent years. It comprises an array of steel plates or walls (referred to as the Web) that are welded into a steel beams and columns frame (Horizontal and Vertical Boundary Elements, HBE and VBE). When subjected to lateral forces, these web plates buckle diagonally and develop a tension field along the opposite diagonal. Under substantial earthquake loads, these plates are allowed to yield along the tension diagonal which provides the necessary energy dissipation during seismic activity. The city of Dubai, UAE has become an international and regional business hub featuring hundreds of tall building structures. The degree of seismic risk that Dubai faces is yet to be agreed upon amongst researchers and structural engineering practitioners. This paper presents the design and analysis of a standard 20-story steel structure employing SPSW to be built in Dubai, UAE subjected to three varying levels of seismic activity reported by researchers. The structural performance of the varying designs is quantified via nonlinear monotonic pushover analyses in the OpenSees platform.
