Mobile Wireless Sensors Networks (MWSNs) are used in several applications presenting difficult/dangerous environment and/or requiring the movement of sensors after initial deployment. Optimizing the use of the limited energy resource in a MWSN is a key challenge for researchers to maintain longer network survival. This paper attempts to provide an energy-efficient data routing solution for […]
In this paper, variable latency speculative Multiply-Accumulator (MAC) architectures are introduced. The proposed architectures use the idea of integrating the results vectors of multiplier in parallel with the accumulator to create asynchronous data paths design. The proposed variable latency speculative MACs consist of two short and long data paths and a circuit is used to […]
In today’s industrialized world, to survive in competitive markets, businesses are required to identify the expectations of their customers, whether explicitly or implicitly, and focus on these needs from the planning to the operational level. To produce customer-oriented products, it is important to extract design requirements that meet the identified needs. The purpose of the […]
The successful operation of a wireless sensor network depends on the proper coverage of the environment, which in turn is affected by the number and location of sensors. In most cases, the sensors are placed randomly in the deployment region, so by default, most coverage is not achieved in their initial deployment. One of the […]
In this paper, we use a nonlinear hierarchical model predictive control (MPC) to stabilize the Segway robot. We also use hardware in the loop (HIL) simulation in order to model the delay response of the wheels' motor and verify the control algorithm. In Two-Wheeled Personal Transportation Robots (TWPTR), changing the center of mass location and […]
With the expansion of human activities, the volume of waste and hazardous waste produced has increased dramatically. Increasing the volume of waste has created challenges such as transportation hazards, cleanup, disposal, energy consumption, and most important environmental problems. The difficulty of unsafe waste control is one of the critical studies topics. Finding the optimal location […]
Applying semiconductor technology, network-on-chips (NoCs) are designed on silicon chips to expand on-chip communications. Three-dimensional (3D) mesh-based architecture is also known as a basic NoC architecture characterized by better energy consumption and latency compared with two-dimensional (2D) ones. Recently developed architectures are based on regular mesh. However, there are serious drawbacks in NoC architectures including […]
A discrete-time (DT) high-resolution and low-power sturdy multi-stage noise-shaping (SMASH) sigma-delta (ΣΔ) modulator is introduced. It proposes major solution for high-resolution applications relying on M-bit digital input-feedforward (DFF) technique which eliminates a power-hungry analog adder before the stage’s quantizer, decreases number of comparators for quantizer implementation and reduces the swing of the integrator’s output and […]
Soft tissue modeling is a challenging issue in tissue engineering. Tissue is a complex environment. It is assumed to represent viscoelastic behavior. Therefore, a complicated process is required to model its stress-strain relationship. In this paper, a non-integer order model is considered for the tissue’s mechanical behavior. The order indicates the amount that the tissue […]
Plasma is a unique phase of matter constituting positively or negatively charged atoms, excited atoms, neutral atoms, electrons, radicals, etcetera displaying a unique role in the nuclear fusion research besides studying electrical discharges in the domain of switching devices and biomedical applications lately. We discuss in this extensive proposition the fundamental plasma characteristics such as […]
