This paper presents the numerical analysis of 2Dimensional (2-D) FCC-MDW of the Optical Code Division Multiple Access (OCDMA) based on variations of transmission bit rate. This 2-D OCDMA code is a combination of 1-D Flexible Cross Correlation (FCC) and 1-D Modified Double Weight (MDW). The performance of 2-D FCC-MDW is evaluated at different bit rate; 622Mbps, 1Gbs and 2.5Gbps and can be demonstrated...
Hyper-threading (HT) technology allows one thread to execute its task while another thread is stalled waiting for shared resource or other operations to complete. Thus, this reduces the idle time of a processor. If HT is enabled, an operating system would see two logical cores per each physical core. This gives one physical core the ability to run two threads simultaneously. However, it does not necessarily...
Compartment model is used for drug delivery explanation in pharmacokinetics. The conventional method to calculate the drug concentration is a numerical method. In the case of multi compartment model is high complexity that difficult to solve by numerical method. This article presents the model complexity reduction using model optimization by Gramian-based input/output balancing of state-space realizations...
After some studies on the HMLP neural network output equation, it was found out that parts of the equation resemble matrix multiplication operation. Therefore, an approach to calculate the output equation of the HMLP using matrix multiplication method was proposed. The proposed approach was simulated and compared with another approach to calculate HMLP output using loops. The result proved that the...
Breast cancer is an abnormal cell locates in the breast tissue. Early detection plays an important role as it helps for long-term survival. The available systems are expensive and need expert to operate it. This paper presents a low-cost and user-friendly breast cancer detection system for end user at home. This system consisted of a pair of home-made antenna, Ultra wide-band (UWB) transceiver to...
Adaptive media playout (AMP) control, common receiver-based technique, is proposed to adjust the playout rate based on the bit-rate fluctuation of network channels to avoid playout interruptions. Most AMP techniques found in the literature adjust playout frame rate based on the buffer fullness or the buffer fullness variation. However, choosing an appropriate threshold to adjust a playout frame rate...
Despite the recent plethora of empirical attempt at improving image quality in the emerging image processing field, image resolution is pressingly fraught with dire challenges today. Image enhancement research remained progressive because of the advancement in contemporary globalization that mandates an improvement in image quality and it becomes essential to run the best quality of image in some...
Mathematical morphological image processing is one of the methods that provides enhancement to the image, improves the image by creating better imaging and focuses on the interest information for the image. Mathematical morphological is applied to the image using various characteristics of the structuring element (SE) for the purposes of observation and comparison. Mathematical morphological is programmed...
This paper presents the design and optimisation of film bulk acoustic wave resonator (FBAR) using nano electro mechanical systems (NEMS) technology in 10–20 GHz frequency band. The effect of thickness, width and length and damping factor of the FBAR are analysed. The air-gap FBAR are designed due its ability to achieve high quality (Q) factor in 10–20 GHz frequency band. The proposed designs achieve...
The leukemia classification based on bone marrow samples highly benefits the doctors in the confirmation of leukemia occurrence from blood test. This paper focuses on the classification of bone marrow acute leukemia cells into three groups namely normal, acute promyelocytic leukemia subtype (M3) and other acute leukemia subtypes. The images are implemented with a series of digital image processing...
One of the challenges faced by automatic facial emotion recognition nowadays is the ability to deal with complicated environmental conditions such as noisy environments. In order to solve this problem, this paper aims to examine facial emotion recognition under noisy environment using empirical mode decomposition (EMD). EMD is a multiresolution technique which is adaptively decomposed nonstationary...
The number of registered vehicles worldwide is increasing dynamically in recent years, over 72 million automobiles were sold in 2015. The AAA Foundation for traffic safety found that driver or passengers spending an average of 46 minutes per day inside a vehicle. Unfortunately, human awareness of indoor air quality in the vehicle cabin is surprisingly low. The quality of air within the vehicle cabin...
A planar nanodevice, known as the self-switching diode (SSD) has been demonstrated to rectify electromagnetic signals at microwave and terahertz frequencies. This diode has a non-linear current-voltage (I-V) characteristic due to the structure of the device which consists of asymmetric nanochannel. To further explore the properties of SSD rectifiers, in this work, silicon-based SSDs with different...
This work demonstrates a simple home automation system that allows the user to control home appliances through wireless. Lights, air conditioners, electronic doors and fans are among the appliances that can be used in this system. In this system, the controlling and monitoring the appliances can perform in two methods. The first method is through a web server meanwhile the second method is by using...
The ability to perform real-time signal analysis on physiological signal is important in today's technology. This allows physician to monitor their patient's health condition and provide the necessary action immediately. To obtain accurate measurement of this signal, proper signal interface between the patient body and the signal analyzer is crucial. In this work, a microprocessor system interfaced...
