Coordinating Resource Use in Open Distributed Systems

In an open distributed system, computational resources are peer-owned, and distributed over time and space. The system is open to interactions with its environment, and the resources can dynamically join or leave the system, or can be discovered at runtime. This dynamicity leads to opportunities to carry out computations without statically owned resources, harnessing the collective compute power of the resources connected by the Internet. However, realizing this potential requires efficient and scalable resource discovery, coordination, and control, which present challenges in a dynamic, open environment. In this thesis, I present an approach to address these challenges by separating the functionality concerns of concurrent computations from those of coordinating their resource use, with the purpose of reducing programming complexity, and aiding development of correct, efficient, and resource-aware concurrent programs. As a first step towards effectively coordinating distributed resources, I developed DREAM, a Distributed Resource Estimation and Allocation Model, which enables computations to reason about future availability of resources. I then developed a fine-grained resource coordination scheme for distributed computations. The coordination scheme integrates DREAMbased resource reasoning into a distributed scheduler, for deciding and enforcing fine-grained resource-use schedules for distributed computations. To control the overhead caused by the coordination, a tuner is implemented which explicitly balances the overhead of the control mechanisms against the extent of control exercised. The effectiveness and performance of the resource coordination approach have been evaluated using three case studies. Experimental results show that the approach can effectively schedule computations for supporting various types of coordination objectives, such as ensuring Quality-of-Service, power-efficient execution, and dynamic load balancing. The overhead caused by the coordination mechanism is relatively modest, and adjustable through the tuner. In addition, the coordination mechanism does not add extra programming complexity to computations.
Revolution in Wheat Production and Total Factor Productivity in Gujarat : The Contribution of Resear ch Investment

This paper has analyzed the growth in TFP of wheat crop and its sources in Gujarat state from 190-91 to 2011-12. The Tornqvist Theil Index has been used to calculate the total output index, total input index and TFP index. Two outputs and ten inputs have been used to construct output and input indices. The results rev eals that during 2000s the area, production and yield of whea t were increased at remarkable rate of 11.62, 14.68 and 2. 74 per cent per annum in Gujarat, followed by Madhya Pradesh and Rajasthan. It has also registered moderate grow th rates of output indices and TFP indices about 1.53 and 1.0 5 per cent per annum, respectively in 2000s. This was contributed by the release of viz., GW-496 and GW-503 in 1989, GW-273 in 1997, GW-322 in 2002, GW-366 in 2006, including proper agronomical practices as well plant protection measures by the then GAU and SAUs in the state, remarkably increased the productivity of wheat in first decade of 21 century. The Investment on wheat research generated 29 percen t IRR found to be a highly paying proposition in study period. The sources of productivity growth indicated that government expenditure on agricultural research and education, balance use of fertilizers and developme nt of ground water as well as canal irrigation in the state, and good monsoon has positive and significant impact on TFP. It essential that growth in TFP needs to be sustaining, through varietal improvements and irrigation developments.
Long ‐ Term Trend of the Tropical Paci fi c Trade Winds Under Global Warming and Its Causes

The recent intensification of trade winds over the tropical Pacific is the strongest ever observed in the past hundred years. This strengthening trend is of great interest in recent research, but the causes are still unclear. Using two relatively long‐term surface wind data sets, the present research shows that there is an overall strengthening trend of the trades in the western equatorial Pacific and an overall weakening trend in the eastern equatorial Pacific. This long‐term trend pattern can be primarily attributed to the cold tongue mode (CTM) rather than to the impact of El Niño–Southern Oscillation (ENSO), El Niño Modoki, or Interdecadal Pacific Oscillation (IPO). The CTM, the second empirical orthogonal function mode of the sea surface temperature anomalies (SSTA) in the tropical Pacific, represents a strong long‐term trend of tropical Pacific background state under global warming. According to the Gill‐Matsuno theory, the easterly winds over the western equatorial Pacific are induced by the equatorial Pacific cooling and warming SSTA associated with the CTM, while the westerly winds over the eastern equatorial Pacific is primarily due to the eastern equatorial Pacific cooling SSTA associated with the CTM. Ultimately, an alternative explanation of past and future changes of the trades is expected to lead to improved understanding of the global climatic impacts of the enhanced trades in tropical Pacific under global warming.
The Validity of 2 D Numerical Simulations of Vertical Structures Around a Bridge

This paper deals with a computational study for evaluating the capability of 2D numerical simulation for predicting the vertical structure around a quasibluff bridge deck. The laminar form, a number of BANS equation models, and the LES approach are evaluated. The study was applied to the deck section of the Great Belt East Bridge. The results are compared with wind-tunnel data and previously conducted computational simulations. Sensitivity of the results with regard to the computational approaches applied for each model is discussed. Finally, the study confirms the importance of safety-barrier modelling in the analysis of bridge aerodynamics. @ 2003 Elsevier Science Ltd. All rights reserved.

SIMULATION OF THE THERMAL MECHANISM IN SEMICONDUCTORS UNDER ACTION OF PULSED ELECTROMAGNETIC FIELD

The paper presents a model taking into account the time character of heat localization and distribution in semiconductor devices unlike the classical Wunsch-Bell linear model describing the thermal mechanism of EM-radiation action on REA. The classification of action levels is given. The nonlinear model permitting to determine the time boundary of heat propagation in the semiconductor device is presented. In the time range t>tcr a uniform volumetric heating of the object takes place, and for t<tcr there is a heat localization in the range of energy release due to the lag of the heat dissipation process behind the energy input process. Taking this into account one determines the energy leading to irreversible results of action. The model allows one to determine the feeblest aspects of REA. PACS: 61.80. -x
Effects of Compensation on Satisfaction How Much Compensation Should a Firm Offer for a Flawed Service ? An Examination of the Nonlinear

This research examines the nonlinear effects of compensation on customer satisfaction in order to determine the optimal compensation after a flawed service. As our core contribution, we argue that the nature of this nonlinear effect depends on the way customers handle a flawed service. Building on the Service-Dominant (S-D) logic, this research introduces two specific failure handling tactics—when customers reject versus accept a flawed value proposition—that affect the shape of the nonlinear function of compensation on satisfaction. Our key hypotheses are tested with two experiments that manipulate 11 compensation levels (0–200%) and the two failure handling tactics (rejection vs. acceptance). Consistent with our logic, both studies reveal an S-shaped curve progression for service rejection and a concave shape for service acceptance. For service rejection, the highest incremental effect of compensation on satisfaction lies in between 60% and 120%. For service acceptance, the highest return in satisfaction is obtained with the first dollars invested in partial compensation. As a major managerial takeaway, firms can use these findings to determine the compensation level that provides the best satisfaction return.
A Pose-Independent Method of Animating Scanned Human Bodies

With the development of 3D scanning technique, animating scanned human body model becomes one of the most active research fields in virtual human modeling. Most of the existing methods have difficulty in animating scanned human body models with arbitrary poses automatically. In this paper, a new framework for pose- independent animating scanned human body is presented. Firstly, feature points and topological structure of the model can be extracted automatically according to Morse function which is based on geodesic distance of human body model and then the body is divided into segments. Secondly, joints can be calculated by analyzing the circularity function of geodesic isolines of the model. Thirdly, vertexes of human body models are mapped to the skeleton and the deformation weights of the vertexes are calculated. The experiments demonstrate that our approach is pose-independent, robust and automatic.

Wavelet-Based Approximation Techniques in Database Systems

growing number of data- base applications require online, interactive access to very large volumes of data to perform a variety of data analysis tasks. As an example, large Internet service providers (ISPs) typically collect and store terabytes of detailed usage information (NetFlow/SNMP flow statistics and packet-header information) from the underlying network to satisfy the requirements of various network-manage- ment tasks, including billing, fraud/anom- aly detection, and strategic planning. This data gives rise to massive, multidimen- sional relational data tables typically stored and queried/analyzed using com- mercial database engines (e.g., Oracle, with massive data sets lies in the use of appropriate data-reduction techniques for constructing compact synopses that can accurately approximate the important fea- tures of the underlying data distribution. Wavelets are a useful mathematical tool for hierarchically decomposing functions in ways that are both efficient and theoretically sound. Broadly speak- ing, the wavelet transform of a function consists of a coarse overall approxima- tion together with detail coefficients that influence the function at various scales. The wavelet transform has a long history of successful applications in signal and image processing (9), (10). Several recent studies have also demonstrated the effectiveness of the wavelet transform (and Haar wavelets, in particular) as a tool for approximate query processing over massive relational tables (2), (5), (6) and continuous data streams (3), (7). Briefly, the idea is to apply wavelet trans- form to the input relation to obtain a compact data synopsis that comprises a select small collection of wavelet coeffi- cients. The excellent energy compaction and decorrelation properties of the wavelet transform allow for concise and effective approximate representations that exploit the structure of the data. Furthermore, wavelet transforms can generally be computed in linear time, thus allowing for very efficient algo- rithms. In this column, we provide a brief overview of recent work and results on wavelet-based approximation tech- niques for relational database systems.
On Chip Transformer Design for CMOS Power Amplifiers

CMOS technology has been widely applied to the design of RF circuits by advantage of low cost, compact size and high system-on-chip integration capability. But the high power amplifier is undesirable building block for C MOS process due to the low breakdown voltage of gate oxide[1]. This problem becomes more serious as the minimum gate lengths are scaled down in each new process generation. The other problem associated with the design of on-chip power amplifiers using CMOS processes is the high loss of on-chip impedance transformation [2]. This is caused by the highly conductive substrate, as well as thin metal and dielectric layers. Recently, many literatures have been presented CMOS power amplifiers in wireless communications comparable to other process ones. The breakdown voltage is one of the inherited drawbacks of CMOS transistor, so typical CMOS power amplifiers adapted the cascode type differential structure as in figure 1 to relieve the voltage stress at the output. Due to the limitation of the output voltage swing, the optimum load for the power cell should be minimized. Also, its structure inevitably needs differential to single-ended conversion at output stage[3].
A hierarchical Bayesian approach to record linkage and population size problems

We propose and illustrate a hierarchical Bayesian approach for matching statistical records observed on different occasions. We show how this model can be profitably adopted both in record linkage problems and in capture--recapture setups, where the size of a finite population is the real object of interest. There are at least two important differences between the proposed model-based approach and the current practice in record linkage. First, the statistical model is built up on the actually observed categorical variables and no reduction (to 0--1 comparisons) of the available information takes place. Second, the hierarchical structure of the model allows a two-way propagation of the uncertainty between the parameter estimation step and the matching procedure so that no plug-in estimates are used and the correct uncertainty is accounted for both in estimating the population size and in performing the record linkage. We illustrate and motivate our proposal through a real data example and simulations.
DISPERSION MODELLING OF PM 10 FOR CHRISTCHURCH , NEW ZEALAND : AN INTERCOMPARISON BETWEEN MM 5 AND TAPM

The performance of two geophysically based high-resolution mesoscale models in simulating the meteorology and dispersion of PM10 for the city of Christchurch, New Zealand is assessed. Christchurch usually experiences severe degradation in air quality during austral winter. The formation of a nocturnal inversion layer and the emissions of particulate matter (PM10) mainly from solid fuel home heating appliances lead to severe haze episodes about 30 nights each winter. The motivation here is to compare the performance of TAPM against MM5 in the complex topographic setting of Christchurch. A strong incentive for using TAPM as a research tool is its computational efficiency and its ability to perform long-term simulations with relative operational ease. The modelling results are compared within the context of simulating meteorology and dispersion with a high-resolution computational mesh (grid spacing of 1 km 2 ) for the period 1-4 August 2000, when the Christchurch Air Pollution Study (CAPS2000) was underway. Initial analysis shows that both models are able to simulate surface-layer meteorology and PM10 dispersion with a satisfactory level of skill (i.e. Index Of Agreement > 0.7 for temperature, u-, and v-components of wind velocity), with MM5 scoring slightly better for all variables.
A Store Manager's Account of His Company Strategy: A Pilot Study

A growing number of scholars in the strategic management field adopt a humanised approach to research via studying strategists and their strategising activities. However, most research is still centred on middle and top management. The pilot study described here illustrates the importance of looking at strategising among first line managers who are becoming increasingly active strategists in certain modern organisational structures. Besides serving as a pilot study for future piece of research, this study attempts to explore how a retail outlet manager perceived his organisational strategy. It also looks at the connection between some of his daily activities and the company’s strategy. This was achieved with a single case study design and analysis of data set produced from observing weekly meetings and interviewing the manager. This pilot study indicates that the store manager sees two strategies within his organisations - an overall strategy and a localised version of that strategy. Further, he is unaware of his strategic agency and that communication is an important part of strategising. These findings support the need for more studies on strategists and strategising activities and confirm the rationale for conducting a full-scale research using a comparative case study approach.
Estimation of permanent magnet motor parameters

To properly design and optimize a control system of a permanent-magnet (PM) machine, the machine model and its parameters must be known. This study presents a method for developing a model and estimating the parameters of a PM machine from standstill time-domain step response data. A dq-axis equivalent circuit model with a general number of damper windings is defined to describe the behavior of the PM machine. Standstill simulation studies were performed on a known PM machine to generate synthetic test data to be used for estimation procedure verification. The stand-still dq-axis model is subjected to a step-input signal and the resulting output is used for parameter estimation. The output-error estimation algorithm is used to estimate the unknown parameters of the dq-axis model. Stand-still tests were then performed on a 4 pole, 1 kW PM machine to obtain data. The PM machine parameters were estimated and the model verified against experimental input and output test data.
Mosquito Larvicidal Properties of Anisomeles Malabarica (L.) Extracts Against the Malarial Vector, Anopheles Stephensi (Liston)

Anopheles stephensi mosquitoes are the leading vector of malaria in Indian subcontinent, parts of Asia and the Middle East. Mosquito control is facing a threat due to the emergence of resistance to synthetic insecticides. Plants may be alternative sources of mosquito control agents. The present study assessed the role of larvicidal activities of methanolic leaf and inflorescence extract of Anisomeles malabarica (L.) against malarial vector Anopheles stephensi Liston (Insecta: Diptera : Culicidae). The larvicidal activity was assayed against the mosquito species at various concentrations ranging from (20 to 100 ppm) under the laboratory conditions. The LC50 and LC90 value of the methanolic leaf and inflorescence extract of Anisomeles malabarica (L.) was determined by Probit analysis. The percentage of mortality of Anopheles stephensi after the treatment of Anisomeles malabarica on I to IV instar larvae from 20,40,60,80 to100 ppm. The LC50 and LC90 values were represented as follows: LC50 value of I instar was 50.24%, II instar was 54.70%, III instar was 59.03% and IV instar was 64.33%, respectively. LC90 value of I instar 106.99%, II instar was 113.33%, III instar was 118.04% and IV instar was 119.94%, respectively. The present results suggest that the effective Anisomeles malabarica leaf and inflorescence crude extracts have potential to be used as an ideal eco-friendly approach for the control of mosquito vectors.
The great enigma : Afghanistan ' s ruby / spinel mines

Whenever possible, quotations found throughout this article have been faithfully transcribed from the original source. The only corrections made have been minor changes in punctuation. As a result, readers may encounter inconsistencies in spelling, etc. My approach has been that, when doubt existed, the original would stand as printed. Certain quotations are quite lengthy. Rather than rewriting or paraphrasing what others have found (and, in the process, claiming it as his own), the author believes that history is better served by repeating their words exactly. Hence the extensive use of quotations from the primary literature (including the original footnotes). In so doing, the danger of misinterpretation is lessened. My own thoughts on the meaning of such quotes follow. This approach allows readers to make up their own minds on the original authors' intent. [1] Some may question the need for such extensive historical detail. I include it in an attempt to show the threads of wisdom connecting us with our past. In today's modern world it is easy to believe that anything worth knowing has resulted from recent study. Such is not the case and I hope that this article can open readers' eyes to the glories (and excesses) of human tradition and history.
Patient Monitoring System through Mobile Devices

Medical personnel, nowadays, use mobile devices to access patient’s information ubiquitously. Security, authentication and privacy on mobile devices must be met in order for the complete adoption of mobile devices in medical field. Also, the bio medical image compression involved should provide a good compromise between the quality of the reconstructed image and the compression ratio involved. The use of hybrid algorithms, seem to meet both the demands. This paper presents one such hybrid algorithm in which Discrete Cosine Transform (DCT) is performed on the approximation coefficients of Discrete Wavelet Transform (DWT). The security aspect is met by performing LSB level substitution in one of the detail sub bands. Results have shown the hybrid algorithm to yield better compression ratio and quality when compared to the two level decomposition performed by DWT.
Gaze-c ouple d Perspective for E nhanced Human-Machine Interfaces in Aeronautics

In aeronautics, many Virtual/Augmented Reality (V/AR) facilities, such as flight simulators, control-tower simulators, remote towers and flight reconstruction software, rely on the assumption that the viewer will most likely stay still in a pre-defined position. For this reason, they can be dubbed Desktop Virtual/Augmented Reality (D-V/AR) interfaces, in contrast with ‘gaze-coupled’ V/AR interfaces, which take into account the viewpoint position within the rendering pipeline.
