In this paper, we consider the problem of energy detection for spectrum sensing over the α-κ-μ fading channel, in a Bayesian framework. The α-κ-μ fading distribution includes popular models such as Rayleigh, Rice, Nakagami-m, Weibull, one-sided Gaussian, α-μ, κ-μ and κ-μ extreme distributions as special cases. We present a fast-converging infinite series expression for the probability of overall error,...
This paper presents a new method for testing materials at the microscale at high temperature under bending in-situ in SEM. The proposed method consists of a straining stage with built-in force and displacement sensors attached to a heating stage inside the SEM. The sample is co-fabricated with the stage to eliminate any misalignment error. The method is applied to test the strength of single crystal...
Energy saving in buildings has attracted many researchers attention. One of the research topics is occupancy detection for each room to automatically control airconditioner, light, heating, etc. by monitoring the temperature, humidity, light, and co2 using the corresponding sensors. For existing data analysis, traditional regression methods such as CART, RF, LDA are often used to predict the occupancy...
When the human body is immobile, it deteriorates after a short period of time. Early and frequent mobilization of a patient or resident is thus critical to maintaining or regaining health. The effects of immobility are often a deterioration of numerous body systems and increased dependence on caregivers to assist with activities of daily living [1]. Complications associated with chronic immobility...
We propose a preferential theme matrix for selecting a problem in carrying out the minor project for 6th semester Computer Science and Engineering (CSE) students. The matrix comprises of emerging technologies, research areas and the application domains as the parameters. It included Internet of Things, Cloud Computing, Mobility and Web Technology as emerging technologies. The focused research areas...
With the evolution of 5G wireless communication systems, we have witnessed an increase in the demand for wireless broadband applications and services. However, fixed allocation of the frequency spectrum has led to an under-utilization of the spectral resources, making it hard to find unoccupied bands to deploy new services. To address the spectrum scarcity problem, a new and promising technology has...
On-line supervised spotting and classification of subsequences can be performed by comparing some distance between the stream and previously learnt time series. However, learning a few incorrect time series can trigger disproportionately many false alarms. In this paper, we propose a fast technique to prune bad instances away and automatically select appropriate distance thresholds. Our main contribution...
In modern cognitive ratio systems, the spectrum is becoming increasingly crowded and expensive; thus spectrum sensing becomes more important than ever before. Traditional spectrum sensing assumes Gaussian noise (or of other given distributions) in general. However when secondary users (SUs) have no prior information about the measurement distributions, the spectrum sensing schemes assuming given distribution...
Crouch Gait (CG) can be observed in the hemiplegia persons after ischemic stroke. Walking with Crouch Gait (CG) shown a large gaits disorder. This paper explores the use of adaptive wavelet extreme learning machine (AW-ELM) to classifying different gait conditions for hemiplegia and healthy subjects. Three participants having a Crouch Gait problem with categories of Mild, Moderate, and Severe gait...
CNC lathe is popular automatic machine tools, which basically requires Programmable Logic Controller (PLC) for the mechanical motion of the machine. This paper discuss the initial implementation of PLC-CNC in controlling the AC induction motor as rotation servo of the lathe turret. The implementation was mainly tested on CNC lathe machine with 4 different conditions that is 270 rpm, 240 rpm, 210 rpm...
This paper proposes a GA-SVM classification method which is applied to the dynamic evaluation of taekwondo. For classifying a dynamic action, we converted a dynamic action signal to a frequency spectrum signal for analysis. However, the useful features were concentrated in a part of the frequency spectrum, and the useless features led to a decline in accuracy, operation speed, and efficiency of the...
The takeover phase from highly automated systems, when the transition phase is short (here 10s), is critical for the driver when he has been out of the driving loop. We conducted a simulator study on 26 drivers to compare three conditions: manual mode (MD), transition from automated driving (AD) to MD with a classical head up display (HUD), transition from (AD) to MD with an augmented reality (AR)...
This paper presents a thorough microscopic simulation investigation of a recently proposed methodology for highway traffic estimation in the presence of mixed traffic, i.e., traffic comprising both connected and conventional vehicles, which employs only average speed measurements stemming from connected vehicles and a limited number (sufficient to guarantee observability) of flow measurements from...
Driving test is critical to the deployment of autonomous vehicles. It is necessary to review the related works since the methodologies summaries are rare, which will help to set up an integrated method for autonomous driving test in different development stages, and help to provide a reliable, quick, safe, low cost and reproducible method and accelerate the development of autonomous vehicle. In this...
Lung cancer is the number one cause of cancer deaths. Many early stage lung cancer patients have a resectable tumor, however, their cardiopulmonary function needs to be properly evaluated before they are deemed operative candidates. Pulmonary function is assessed via spirometry and diffusion capacity. If these are below a certain threshold, cardiopulmonary exercise testing (CPET) is recommended. CPET...
In this paper, A test bench system used in the test of UAV is put forward. The system is consisted of four parts which includes bearing part of UAV, ground support position, transmission mechanism and measuring weight parts. Bearing part of UAV is used for placing the object to be measured which is connected to one end of the drive mechanism through the connecting shaft, The other end of the drive...
This article describes the design and development of an electronic data glove to study hand movement of individuals with movement impairments due to brain injury. Customized stretch sensors were used to measure the five metacarpophalangeal joint angles. The main features of the device are cost-effective, lightweight, and high memory capacity. It records the bending angle of all 5 metacarpophalangeal...
This paper presents an optimized SRAM that is repairable and consumes less power consumption. To increase the number of good SRAMs per wafer, redundancy logic and e-fuse box are added to SRAM, thereby building SR SRAM. In order to reduce power consumption, power on and off states are added into SR SRAM, consequently constructing LPSR SRAM. Also the testing method of the SoC which has been successfully...
Smartwatches become increasingly powerful and popular. These personal devices carry multiple sensors that continuously measure, collect, and analyze various sensitive personal information. Therefore, a strong and user friendly authentication mechanism is much needed to prevent illegitimate accesses to those devices. However, traditional protection approaches are far from sufficient and desirable for...
Positioning and timing subsystems are crucial components for cooperative and autonomous driving. Both during development and for validation and certification, it is crucial that advanced testing systems are available. To support the complete development life cycle, testing tools for hardware in the loop testing, open test track testing, and public road testing are required. This paper gives an overview...
