The intracellular pH of cancerous cell is commonly acidic while the intracellular pH of normal cell is neutral. The objective of this study is to study the electrical characterization in terms of resistance between the pH of sensing material with the intracellular pH of the cells. Three different pH of Graphene Oxide (GO) were used as a solvent to analyze their interaction towards breast cancer cells (MCF7) and breast normal cells (MCF10a). GO which produced by Hummer's method was used due to their solubility and biocompatibility characteristics which easily diffuse through the cell. In this experiment, the characteristics of GO were analyzed and confirmed by using Atomic Force Microscopy (AFM) and Fourier Transform Infrared spectroscopy (FTIR). In order to measure the resistance of MCF7 and MCF10a cells after treated with GO for 24 hours, gold electrodes with 10 μ-gaps of interdigitated electrodes (IDEs) were used. The results were obtained for three periods of time which were immediate, 5 minutes and 10 minutes after the treated cells being exposed at room temperature. The results show that the resistance of MCF10a cells increased after treated with higher pH of GO which is pH 7 and the resistances of the MCF7 cells decreased as the pH of GO increased to pH 7. Finally, the viable cells were calculated by using haemocytometer in order to prove that the increased of the resistances were due to the increased number of viable cells.

Virtualization detection on publicly exposed computing resources can have serious security implications. It can lead to the exploitation of known vulnerabilities in the virtualization software and also to carrying out attacks on shared virtual resources. The impact of such attacks can be very severe on public clouds, as numerous clients who subscribe to the cloud services share the infrastructure. Yet the threat of virtualization detection has been often overlooked by many cloud service providers. In this paper, we show how the three popular public clouds namely the Amazon EC2, Google Computing Engine and the Microsoft Azure clouds are vulnerable to this risk. We summarize the various approaches used for virtualization detection and present the results obtained on the public clouds from an attacker's perspective. We demonstrate that the publicly exposed guest instances are not hardened to prevent this information leakage to the attackers. In addition to the prior known approaches, we also propose and demonstrate a new approach for detecting virtualization, based on the location and size of the descriptor tables.

Cellular Neural Networks (CNN) were developed by Chua and Yang in 1988. The main characteristics of CNN are the local connection and the parallel signal processing. CNN consists of cells connected each other and they are arranged in a lattice. CNN is applied to the image processing because the its structure is similar to the image data. The performance of the CNN depends on the parameters which is called the template. When the template has a good influence of the processing, CNN can perform complex processing. In this study, we propose switching two templates CNN. The feature of the proposed method is switching two templates by using the maximum and the minimum output values surrounding the cell. We consider that cells are placed in the input image; edge, background, etc. We apply the proposed method to edge detection and investigate its performance.

Reliability and robustness of Internet of Things (IoT)-cloud-based communication is an important issue for prospective development of the IoT concept. In this regard, a robust and unique client-to-cloud communication physical layer is required. Physical Unclonable Function (PUF) is regarded as a suitable physics-based random identification hardware, but suffers from reliability problems. In this paper, we propose novel hardware concepts and furthermore an analysis method in CMOS technology to improve the hardware-based robustness of the generated PUF word from its first point of generation to the last cloud-interfacing point in a client. Moreover, we present a spectral analysis for an inexpensive high-yield implementation in a 65nm generation. We also offer robust monitoring concepts for the PUF-interfacing communication physical layer hardware.

This paper presents a 2.4GHz single chip quadrature low noise amplifier (QLNA) and IQ mixer in standard 180 nm CMOS technology. Quadrature generation is achieved in the RF path using a type-II RC-CR network which exhibits good phase and amplitude balance while reducing insertion loss making it less vulnerable to process variations and external components. Various circuit techniques such as PCSNIM and low power optimization are adopted to acquire good performance with respect to power consumption and cost. In the implementation of LNA stage, an inductive source degeneration and inductive loading is used for low noise, high gain and good input matching. The mixing stage integrates an active IQ mixer with low pass filter (LPF) load. Current bleeding technique is adopted to further improve the conversion gain and noise performance. The extracted results of this proposed design shows a high gain of 22dB at IF frequency of 100MHz with a noise figure (NF) of 9dB. The input 1-dB compression point (P1DB) and input referred third-order intercept point (IIP3) are −20 dBm and −11dBm respectively. The overall QLNA-mixer consumes 3.5 mA of current from a 1.8 V headroom.

A 2xVDD output buffer with process and voltage (PV) compensation technique is proposed to keep slew rate (SR) within predefined ranges regardless PV variations. The reason of temperature variation is not considered is that it is found to be relatively low correlated to slew rate for 90 nm process or better. All bias voltages in process and voltage variation detectors are generated from bandgap circuits such that variations have been guaranteed by simulation within less than 4.10%. The data rate is 650/500 MHz given 1.0/2.0 V supply voltage with 20 pF load, respectively, by physical measurements. The Δ SR improvement is 30.7% and 31.4% for 1× VDD and 2× VDD, respectively, when the proposed PV compensation design is activated.

The digital low dropout (LDO) voltage regulator are widely used in digital circuits which has multiple power domain and large dynamic supply ranges in System on Chip (SoC) application. The closed-loop transfer function of digital LDO is hard to derive because of two factors. One is mixture of discrete- and continuous-time operation. The other is the nonlinear comparator gain. However, the availability of open-loop transfer function is also limited by the non-constant feedback factor. Therefore, the prediction of digital LDO performance in the early design stage is difficult. Moreover, designer cannot explore the design space effectively. This paper builds a time-domain behavior model in MATLAB/Simulink to estimate transient response performance of DLDO and voltage ripple in steady state. This paper avoid complex mathematical operations. The result of the estimation is compared with transistor level simulation by HSPICE.

Greenhouse generally is a house that isolates its internal environment from its external environment. The aim of this work is to create an artificial environment for plants where the goal is to accelerate plant growth. This will contribute to agriculture industries like in fruits and vegetables production. The project involves the use of ARM board as platform to collect and control variable parameter and Web-based graphical user interface for monitoring and controlling the system. It is shown that the greenhouse environment can be monitored and controlled through Internet via built in Wi-Fi on the controller board.

The analysis was done on the particles mobility changes when the medium conductivity varied. The analysis was also done when the particles suspended in different mediums conductivity. The effect of dielectrophoresis on the velocity of the particle when the frequency increased has been successfully discovered.

In this study, we investigate the spread of chaotic behavior to complex network. We propose three types random network models with different network topology. In each network model, the proposed network is composed of coupled chaotic circuits when one circuit is set to generate chaotic attractor and the other circuits are set to generate three-periodic attractors. By using computer simulations, we investigate ratio of propagation and spread of chaotic behavior by changing the initial chaos position. We compare their differences of simulation results in scale-free and random networks. From the simulation result, in scale-free network, the ratio of propagation is effected by clustering coefficient and path length.
