As a result of the enormous demand placed on this valuable resource, documentation has become a paramount requirement in their effective utilisation. Such documentation relate to inventories, maintenance records, costs, utilisation and breakdown records, etc. This book presents the development and application of INTELLIPLANT, a web-based system plant information management system. The system evolved as an integration of a web-based Relational Database Management System (RDBMS) and a Model Base Management System (MBMS). The RDBMS was designed from forms collected during a pilot/ field investigation, while the MBMS emerged from the assemblage of time series models developed from a rigorous analytical procedure of historical records. INTELLIPLANT has the capacity to generate over 20 real-time history reports on-line through its RDBMS structure. ····· 1036121266

Hence, it is necessary to develop a simple and efficient technique to enhance the lateral strength, stiffness, and energy dissipation potential of such non-ductile RC frames. A strengthening technique consisting of steel caging to increase the lateral strength of deficient ground-storey columns and aluminium shear-yielding dampers (Al SYD) to improve the overall energy dissipation potential and lateral stiffness is proposed to enhance seismic performance of non-ductile open-ground-storey RC frames. A performance-based design method was developed with the objective that the structure should develop sufficient flexural strength and inelastic rotation at a target yield mechanism to withstand the probable seismic demand. ····· 1036121188

Introduction of LTE improved the situation to some extent. However as a high percent of mobile data traffic is generating from indoors, LTE at higher frequencies cannot really meet the ever increasing demand of data traffic and reasonable QoS. This Book provides an analysis of the network throughput with LTE technology that includes macro and indoor traffic distribution pattern using system level simulation environment. Simulation results show that with increasing percentage of indoor traffic, the throughput of macro network decreases significantly. Lately, two possible solutions emerged to offload the indoor traffic by WiFi or Femtocell. A brief overview of the two solutions is presented and the more promising, femtocells are further evaluated. The analysis shows the increase in macro network throughput by offloading the traffic via femtocells. Deployment of Femtocells can surely be of great interest to both users and operators providing users with good QoS and operators with low CapEx and OpEx while providing the high revenue. ····· 1036121128

This particular rescue robot has the capability of moving through rough terrain with the help of treads acquiring the ability even to climb the stairs. The other task that it can perform is that it will detect fire and will extinguish it. Any two disasters of the same type do not have damages that are alike and, in the same disaster, no two regions are likely to exhibit similar damage characteristics. Thus, rescue robotic devices should be adaptable, robust, and predictive in control when facing ever changing scenarios. Furthermore it can be used as a platform for carrying out various other tasks like fire extinguishing, mine detection or another most recent use for defusing IED s (Improvised Explosive Devices). With the help of this robot the position of a person under rubble can also be determined without compromising the safety of the rescuer. Our idea is to incorporate as best we can the techniques used by rescuers into our robot so that may demonstrate its usage in any high risk area involving human morbidity thus providing us with a combination of man and machine coupled with safety. ····· 1036121021

For a rich set of applications implementing Intelligent Highways, like application related to road safety, traffic monitoring and management, road disaster mitigation etc. the road side infrastructure plays a vital role for any VANET. This is the reason that efficient communication between the vehicles and the road side infrastructure is required. Meeting this requirement becomes very difficult as nodes in a VANET are highly mobile and thus the network topology is highly dynamic. This work aims to achieve a better vehicle to infrastructure communication. The application under consideration is providing a zero traffic lane (Z-Lane) for an ambulance using VANET. To achieve the goal the first step is to identify a suitable vehicular mobility model. This monograph documents the related literature survey. The simulation based experimental setup for the said application using SUMO(Simulation of Urban Mobility) and NS2(Network Simulator 2)are thoroughly explained in this monograph. ····· 1036120990
für 71.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray To increase the production in mines, it is essential to increase the availability of heavy earth moving machinery (HEMM). A number of maintenance schedule exists for maintenance of HEMM. A new type of maintenance schedule namely `noise spectrum based maintenance` is introduced in this book. This type of maintenance is a type of `preventive maintenance` as opposed to the historical practice of `periodic maintenance` based solely on operating hours. In this case `preventive` refers to premature or significant acoustical degradation as opposed to operational degradation. One major advantage of this maintenance strategy is its simplicity. It requires only the noise spectrum to be obtained at regular intervals for HEMM. The maintenance approach reported in this book are based on extensive experimental work carried out in the field and therefore can be confidently used by the mining industry. This book will be of immense help to maintenance personnel in mining industry, academicians and researchers working in Mining Engineering domain. ····· 1036120885

für 71.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray This book presents the development of Ultra Wideband (UWB) technology, its standardisation, UWB pulse parameters, different UWB transceiver architectures and its applications. Wireless Sensor Networks (WSN) is one such application where UWB technology can be employed. The WSN applications demand portability and ultra low power consumption from its components. UWB impulse radio transceiver, which is one of the suitable architectures for WSNs, uses coherent reception and digital domain pulse correlation. The current UWB receiver uses significant hardware parallelism in the digital backend. The hardware parallelism ensures successful receiver operation in worst case channel conditions. However, it significantly increases the power consumption and deters the UWB receiver from being employed in the WSN. In UWB communication the channel conditions are not always worst and continuously vary with time and environment. This book proposes a novel real-time reconfigurability algorithm that estimates the channel conditions and effectively utilises the hardware resources by adapting the receiver to different channel conditions which considerably reduces average power consumption. ····· 1036120711

This book, therefore, provides a new framework of risk assessment of power systems which combines the precision of a probabilistic method with the flexibility and correctness of customer and interruption parameters. The framework is presented in the form of case studies and a new reliability worth index is derived. The risk-based approach applied to the interpretation of risk-based interruption cost (RBIC) index significantly influences the perception on the network`s reliability performance and allows the uncertainty in a network planning or operation decision to be quantified. Use of the new reliability worth index offer more flexibility in reliability worth assessment and produce more accurate results.

The exercise of market power has antisocial impacts in the liberalised electricity markets. It results in inefficient short-term dispatch outcomes, and affects the efficiency of longer-term generation investment decisions. And thus, it results in power price rises and substantial wealth transfers between electricity customers and generators. Electricity market regulators around the world tend to be interested in mechanisms for predicting marker power ex ante and detecting and controlling the exercise of market power ex post. The common indices of ex ante market power indicators however, mostly disregard transmission constraints, variation of wind farms capacities, and dynamics of electric power systems. This paper carries out a probabilistic study of market power using an index termed Probabilistic Transmission-Constrained Pivotal Supplier Indicator (Probabilistic TC-PSI). Two probabilistic approaches (a) Monte Carlo Method (MCM), and (b) Two-Point Estimation Method (T-PEM) are employed in the probabilistic study and then compared to each other. ····· 1036120233

However, MAC layer restrains the performance improvement due to its different overhead. We proposed an efficient MAC scheme Frame Aggregation Method that would mitigate the overhead inefficiency. The principle of Frame Aggregation Method is to aggregate as many as possible packets from the upper layer into large frames. Thus, the frames will be very large as long as there are enough packets to be aggregated. To support various functionalities provided by Frame Aggregation Method , new MAC frame formats and the corresponding dynamic logic such as queuing mechanisms are designed.
