After total hip arthroplasty (THA), restoration of hip center of rotation (COR) is essential to ensure stability of the prosthetic hip and longevity of the prosthesis. Our aim was to determine whether, and how, the COR changed postoperatively compare

Most fungal infections primarily occur in immunocompromised patients. We describe a case of osteomyelitis involving the first metatarsal head due to Cryptococcus neoformans in a previously healthy immunocompetent patient. She was treated with surgica

In this paper, a nonlinear controller with dead-zone and saturation is proposed in order to improve the antishock performance. Since using dead-zone and saturation improves the stability margin, we can use a higher gain for the dead-zone than in the

In this paper, we present a novel control method with clamping force estimation for an electric parking brake system. This simple control structure can be implemented at low cost as it does not require a clamping force sensor. The characteristic curv

This paper presents a voice coil motor (VCM) prediction based dual-stage actuator (DSA) control for fast seek and settling times. In the conventional control systems, VCM follows a reference signal, whereas a micro-actuator (MA) seeks a VCM position

A fault detection method with parity equations is proposed in this paper. Due to its low cost implementation, the velocity of the motor is not measurable in electric parking brake (EPB) systems. Therefore, residuals are not reliable when estimating t

In this paper, we present a new tracking control method for holographic digital data storage systems. Holographic data storage systems that use disk media need a different tracking method from those that use optical and hard disk drives. Here, we pre

Self-servo track writing is a process of writing servo bursts on a subsequent track using servo bursts from the previously written track as a reference. A fundamental obstacle in self-servo track writing is radial error propagation due to written-in
