In today's era, Wide-area monitoring plays a major role in modern power system (smart grid). To monitor this, we need to place Phasor Measurement Units (PMUs) in the system in such a way that the complete observability of the system is achieved. PMUs have the capability that they can provide synchronized measurements of both voltage and current. In this paper, a Minimum Connectivity Based Reduction...
Reverse logistics is an activity associated with a product/service after the point of sale, the ultimate goal to optimize or make more efficient aftermarket activity. Enterprises that have implemented reverse logistics have been able to enhance consumer service and response times, minimize environmental influences by minimizing waste and enhance complete corporate citizenship. In this connection,...
Across broadband access networks, significant opportunities to minimise energy consumption exist at the application and networks level but are not fully coordinated. For example, an application can tune its QoS in accordance with the available power levels of network systems. As a first step towards enabling energy efficiency, we study the interrelationship between energy consumption and application...
Neurofibromatoses (NF) are a group of genetic multisystem disorders involving products of all three germ lines: Neuroectoderm, mesoderm, and endoderm. Four varieties of this disorder have been described.
Design of Fractional Order PID controller (FOPID) for speed regulation of DC motor is presented in this paper. In comparison with conventional PID, FOPID is more flexible and trustworthy to control higher order systems. The FOPID exhibits the Iso-damping property to enhance the robustness of closed loop response of the system against gain variations. According to parameters adjustment problems of...
The main aim of this paper is to design PID control PWM module using field programmable gate array (FPGA) technology. FPGA based realization offers high speed, complex functionality, consume less power, and provides parallel processing. In this paper, we have implemented PID control PWM module on programmable logic design software Quartus II and verified on DE0 Nano Board (Cyclone IV FPGA family of...
An 80GHz bandwidth distributed amplifier with 7Vpp differential output swing and PO1dB of 13 dBm per side, a 125GHz bandwidth PIN-diode SPST switch with 23dBm output compression point and over 22 dB of isolation up to 160 GHz, and a 40–100GHz bandpass filter with less than 3dB insertion loss are reported in a 90nm SiGe BiCMOS process. The circuits represent critical building blocks for analog transmitter...
We present the electrical characteristics of the first 90nm SiGe BiCMOS technology developed for production in IBM's large volume 200mm fabrication line. The technology features 300 GHz fT and 360 GHz fMAX high performance SiGe HBTs, 135 GHz fT and 2.5V BVCEO medium breakdown SiGe HBTs, 90nm Low Power RF CMOS, and a full suite of passive devices. A design kit supports custom and analog designs and...
The trio emerging technology-cloud computing, semantic web and multi-agent systems — has been pivotal in catalyzing the paradigm shift in Information Technology (IT). Despite Enterprise Resource Planning, Supplier Relationship Management systems, and other solutions; current IT systems are unable to extract and share knowledge from text on the web without human intervention. This has made the restructuring...
Scaling both the fT and the fMAX of SiGe HBTs is quite challenging due to the opposing physical device requirements for improving these figures of merit. In this paper, millisecond anneal techniques, low temperature silicide and low temperature contact processes are shown to be effective in reducing the base resistance. These processes when combined with a novel approach to address the collector-base...
Magnetoencephalography (MEG) has been shown to be a useful diagnostic tool for presurgical evaluation of pediatric medically intractable partial epilepsy. MEG source localization has been shown to improve the likelihood of seizure onset zone (SOZ) sampling during subsequent evaluation with intracranial EEG (ICEEG). We investigated whether frequency-dependent ictal MEG onset source localization further...
In this paper, A continuous glow discharge is investigated which takes place between the two electrodes out of which one is floating in air. The powered electrode geometry is a disk while the floating electrode is a graphite rod with a sharp tip. The voltage of around 5kV and 20 kHz was applied to the powered electrode. This was generated using a half bridge resonant converter operated in above resonant...
Across broadband access networks, significant opportunities to minimise energy consumption exist at the application and networks level but are not fully coordinated. For example, an application can tune its QoS in accordance with the available power levels of network systems. As a first step towards enabling energy efficiency, we study the inter-relationship between energy consumption and application...
We report results from a 130nm Indium Phosphide (InP) double heterojunction bipolar transistor (DHBT) technology. A 0.13×2µm2 transistor exhibits a current gain cutoff frequency ft >520GHz, with a simultaneous extrapolated power gain cutoff frequency fmax>1.1THz. The HBTs exhibit these RF figures-of-merit while maintaining a common-emitter breakdown voltage BVCEO=3.5V (JE=10µA/µm2). Additionally,...
Given the growing complexity and energy consumption of customer premises equipment (CPE) in smart home networks and the consequent need for optimal energy usage, there is a need for better coordination of the power operational states of the CPE devices. In particular, this paper presents an energy model to synchronise the behaviour of a Home-Gateway (HG) with the CPE such as a set-top box with exemplar...
In this paper the capability of Relevance Vector Machines to perform multiclass classification has been illustrated. It has been demonstrated how faults in an analog circuit can be diagnosed by analyzing these faults as a multiclass machine learning problem. A simple first order Op-amp RC circuit validates our methodology which can be further applied to more complex analog circuits employing a larger...
A 0.25µm InP DHBT process has been developed for THz frequency integrated circuits. A 0.25×4µm2 HBT exhibits an extrapolated ƒt/ƒmax of 430GHz/1.03THz at IC =11mA, VCE= 1.8V. The transistors achieve this performance while maintaining a common-emitter breakdown voltage (BVCEO) >4V. Thin-film interconnects and backside wafer processes have been developed to support selected IC demonstrations. The...
Nature's Real Estate such as water, minerals, oil & gas, and coal is the precious gift available for the welfare of mankind since time immemorial. In spite of the efforts initiated by many countries in the development of non-conventional energy resources, it is too early to visualize that the gap between supply and demand of energy could be bridged in the near future. With this backdrop, the policy...
Passive systems are playing prominent role in the design and development of innovative reactor systems because of generally perceived enhanced safety and reliability on account of reduced human intervention and ample grace period for the operator in case of accidental conditions. These systems are considered to be more reliable than the active systems, due to their dependence solely on the natural...
In this paper we describe a solution for incorporating human emotions into the conversational system for automatic ontology construction. We find semantic similarity using LSA, Latent Semantic Analysis, between the new sentence and the corpus corresponding to each human emotion stored in ontology, structured database of sentences corresponding to human emotions. If the semantic similarity of the new...
