In this paper, a CMOS monolithic calibrated position-sensitive detector (PSD) for detecting light-spot position applications is newly proposed. A calibration technique is proposed in this work. With the calibration circuits, the proposed chip successfully detects the position of a small light in a real environment. Before performing the proposed calibration circuits, the maximum linear error is 54...
In this paper, a CMOS driving circuit with compensation function for gyroscope applications is newly proposed. Associating with closed-loop driving circuits, the compensation technique is proposed mainly to maintain the stability of gyroscope when it is possibly operated under extreme environment. After performing the proposed compensation technique, this problem coming from stability can largely...
A comparative analysis of Boost and Buck-Boost Converter for power factor correction (PFC) with diode bridge rectifier is discussed in this paper. Boost and Buck-Boost PFC converter faces very high THD and poor PF in open loop control. Thus Hysteresis Band Current controller is used to reduce the Total harmonic distortion (THD) of input current waveform and improve power factor. PFC is attained here...
The aim of simulation technique for production line is to find out the most feasible scheme which designers made for the project. Simulation technique can verify the actual effect of the project from the schemes. Combined with the actual production mode, the article analyzed the bottleneck of production efficiency under different shifts. It mainly discussed the value of simulation technology for production...
By using HDCP engineering code as a verification prototype, the critical path was identified and extracted from timing path report. The gate monitoring report could be getting from monitoring gates which are corresponding to the critical path in the netlist, while doing simulation with different testbench. Through the comparison between the path report and the gate monitoring report, coverage rate...
Recent years have seen increased interest in the use of off-grid solutions for electrification of rural areas. Off-grid electrification (such as solar home systems and micro-grids) are particularly applicable to the rural African context, where little infrastructure exists and in many regions grid extension is prohibitively expensive. To be economically viable, these systems must maximize the power...
In the paper it has been proposed to use a fuzzy-controller in telecommunication networks for improving the routing process. An architecture of the fuzzy-controller was developed. Linguistic variables, terms and membership functions for input and output values have been defined. Rules base has been developed. The operation of the fuzzy-controller has been simulated.
This paper presents OCCI simulation extension, a generic simulator for any kind of resources. To achieve that, we first study the position of cloud simulator entities against OCCI model. Afterward, we define an OCCI extension simulation. In order to study the usefulness of this extension, we implement in the second time a module for Eclipse IDE to define OCCI configuration graphically. This tool uses...
Increasing demand of multimedia functions in mobile influenced systems provides limitations to battery usage in terms of power. To overcome this problem SLIMbus is designed by MIPI alliance which gives higher bus bandwidth by supporting more number of data channels, supports clock gear mechanism that gives less power consumption in hand held devices by changing the clock frequency dynamically. SLIMbus...
Robotic workplaces are now commonplace and not just in modern automotive companies. Robots help to reduce the cycle time of assembly lines and enhance quality assurance regarding handmade production. The demands placed on a robotic workplace have changed greatly since the first standalone installation. Complex assembly lines incorporating robotic cell and multi robot cooperation represented a typical...
Floating point number can co-occurrently develop a prominent range of numbers and a high level of precision. Multiplication of floating point numbers found extensive use in wider range of technological and commercial calculations. It is needed to implement faster multipliers involving limited area and consuming reduced power. An IEEE-754 format established multiplier applying Vedic Urdhva — Tiryagbhyam...
In Data Communication [1], when two or more stations send the data at the same time, there are possibilities that the data packets from different stations may collide. Thus, a protocol is required which may coordinate the data transfer among the computers that share the medium. One such MAC (Medium Access Control) Protocol uses sharing of the transmission channel using three methods namely token passing,...
Temporal Derivative Cellular Neural Network (TDCNN) is an important class of neural networks. These networks find a lot of application in real life mostly in the real-time image processing. However, the main challenge is to implement this network in hardware. Therefore, in this paper, sinh-domain realization of single cell architecture of TDCNN which forms the only building block of complex TDCNN...
Built in Logic Block Observer (BILBO) is a bank of flip-flops which are used for self-testing for complex digital IC's in pipeline approach. As per the Launder's principle, KTln2 heat is dissipated if there is any loss in bit. Since BILBO is designed with irreversible logic gates we observe large amount of leakage power which affects its performance. So by keeping this as main criteria, our paper...
When complex system designs with complex specifications, where more than one address and data need to process simultaneously, than various protocols are used to process. There are various serial and parallel protocols are significant to used. But, now a day, AMBA AXI protocols are generally used for the interface. In this research work we present a flexible module with generic interfaces. Our implementation...
This paper proposes a delay-aware resource provisioning policy for virtualized wireless networks (VWNs) to minimize the total average transmit power while holding the minimum required average rate of each slice and maximum average packet transmission delay for each user. The proposed cross-layer optimization problem is inherently non-convex and has high computational complexity. To develop an efficient...
When assessing the robustness, vulnerability or resilience of transportation networks, topological performance indicators of the considered network are often used. Approaches that integrate operating conditions and organisational aspects are sorely lacking in the literature. In this paper, mass railway transportation network's performance indicators that take into account the operating conditions...

In multi-controller software-defined networking (SDN) environments, a flow whose path includes switches that are managed by different controllers experiences increased flow setup latency, which is critical for delay-sensitive applications. To address the issue, we propose an optimal controller assignment scheme that minimizes the average flow setup latency while limiting load imbalance between controllers...
In this paper, we propose a new structure that combines Grey Prediction with Line of Sight (GP-LOS) to predict yaw angle in order to achieve path following for autonomous underwater vehicle (AUV). The proposed structure can be described by two stages. First, we use grey prediction to predict the position coordinates of the next time. Second, taking advantage of the principles of the Line of Sight,...
