When cardiac arrest occurs to patients, the emergency medical service(EMS) is a top priority for saving their life or avoiding the critical injury to the brain and internal organ. Among the EMS, cardiopulmonary resuscitation (CPR) is crucial to save their life. The implementation of CPR is usually determined by the carotid artery palpation method. However, the method has several shortcomings in the...
We report a multimodal microscopic imaging system which offers high-frequency ultrasound B-mode, acoustic radiation force impulse (ARFI), and multispectral image for examination of excised human tumor ex vivo. Examination of excised tumors from the lesions of interest is one of the crucial procedures during surgical operations to treat cancer. Particularly, if tiny reaming tumors exist at the surgical...
The paper suggests a therapeutic device for hemiparesis that combines robot-assisted rehabilitation and mirror therapy. The robot, which consists of a motor, a position sensor, and a torque sensor, is provided not only to the paralyzed wrist, but also to the unaffected wrist to induce a symmetric movement between the joints. As a user rotates his healthy wrist to the direction of either flexion or...
In this paper, we propose a framework that can prevent accidents due to careless or inattentive driving by providing the necessary traffic information to the driver. The proposed system complements the driver by providing the missed cognitive information regarding the traffic. The proposed system is divided into three parts. First, the system checks the condition of the driver in real time, and detects...
There are a number of different attributes to describe ontology of proteins such as protein structure, biomolecular interaction, cellular location, and protein domains which represent the basic evolutionary units that form protein. In this paper, we propose a mathematical approach, formal concept analysis (FCA), which toward abstracting from attribute-based object descriptions. Based on this theory,...
Recent efforts towards mobile cloud propose to offload mobile applications to cloud servers for the improved performance and battery life of mobile devices. However, existing schemes completely ignore the costs of cloud resources by assuming that idle servers are always available for free of charge. These unrealistic assumptions make each server run only a small load to achieve the guaranteed high...
An estimated 20–50 million people get injured and at least 1.2 million people die in automotive accidents every year. To avoid this, several security systems such as lane departure warning system, vehicle detection system, advanced cruise control system, etc., have been developed. But they are very expensive. In our research, we focus on developing low cost intelligent vehicle systems. In this paper,...
Cloud infrastructure providers deploy Dynamic Resource Management (DRM) to minimize the cost of datacenter operation, while maintaining the Service Level Agreement (SLA). Such DRM schemes depend on the capability to migrate virtual machine (VM) images. However, existing migration techniques are not suitable for highly utilized clouds due to their latency and bandwidth critical memory transfer mechanisms...
A new rigidity penalty was developed to improve the accuracy of an intensity-based B-spline deformable image registration, and its impact on the displacement vector field (DVF) within cervical vertebrae was investigated. The developed rigidity penalty was tested on ten (10) pairs of cone-beam computed tomography (CBCT) scans. The results were compared to those with a conventional rigidity penalty...
This paper presents a development of program in long-term dynamic stability. The long-term voltage instability is caused by reactive-power reserves. The reactive-power reserve problems are especially determined by over-excitation limiter (OXL) and under load tap changer (ULTC), etc., which are the power device having a few to 10's minutes of time periods. The previous method estimating long-term voltage...
Existing thermal management systems for microprocessors assume that the thermal resistance of the heat-sink is constant and that the objective of the cooling system is simply to avoid thermal emergencies. But in fact the thermal resistance of the usual forced-convection heat-sink is inversely proportional to the fan speed, and a more rational objective is to minimize the total power consumption of...
