Channel allocation in wireless data center networks (2011)

Unbalanced traffic demands of different data center applications are an important issue in designing Data center networks (DCNs). In this paper, we present our exploratory investigation of utilizing wireless transmissions in DCNs. Our work aims to solve the congestion problem caused by a few hot nodes to improve the global performance. We model the wireless transmissions in a DCN by considering both the wireless interference and the adaptive transmission rate. Moreover, both throughput and job completion time are taken into account to evaluate the impact of wireless transmissions on the global performance. Based on this model, we formulate the channel allocation in wireless DCNs as an optimization problem and design a genetic algorithm (GA) based approach to address it. To demonstrate the effectiveness of wireless transmissions as well as our GA-based algorithm in a wireless DCN, extensive simulation study is carried out and the results validate our design.
Discussion of results (2012)

The problems of optics, acoustics and quantum mechanics, the theory of partial differential equations, probability theory and number theory lead to the need to study oscillatory integrals with large values of the parameter.
Test program development in VLSI testing (2002)

This paper describes how an automatic test program generation environment is developed by making use of the Summit Design's TDS software modules as the basic building blocks. A new design-to-test process flow is defined. A solution of eliminating conversion errors of simulation post-processing is also proposed. In this approach, a functional test program can be generated within minutes, which dramatically shortens the test program development time and gets a new product faster to market.
Wellbore Stabilization Increases Fracture Gradients and Controls Losses/Flows During Drilling (2004)

Abstract This paper presents formation treatment technology that helps (1) reduce well-construction costs, (2) improve and maintain wellbore integrity during drilling, and (3) enable economical production from reservoirs with challenging drilling and cementing conditions. The technology presented helps stabilize and improve wellbore conditions by several different downhole mechanisms and types of sealing materials. This paper emphasizes one of the most promising of these mechanisms: increased near-wellbore fracture gradients (NWFG), or wellbore pressure containment (WPC) caused by stress alterations in the rock surrounding cracks induced by sealants forced into the cracks to slightly widen them near the wellbore. Industry studies1,2 sometimes refer to these stress alterations as "stress cages." The alteration process3 has been described as a WPC failure mechanism in which tensile force switches to compressive force as the fracture is sealed near the wellbore. Each side of the wellbore connecting the two fracture wings is moved by the compressive force in directions perpendicular to the fracture plane and proportionally to the increase in fracture width. As a result of this WPC improvement, engineers may plan wells with fewer casing/liner strings and with upper hole sections of smaller diameter. Under certain conditions, it is possible to construct the "one-trip" well, wherein only one bit-run is needed to drill to total depth (TD) from the surface-casing shoe. The new technology can also help prevent or mitigate unstable hole conditions that interfere with the drilling process. Wellbore-stabilization technologies presented are designed for wells with narrow mud-weight windows (MWW) that can lead to well-construction incidents such as (1) loss of circulation, (2) failed shoe tests, (3) poor annular zonal isolation, (4) the need for extra strings of casing to enable drilling through depleted formations, and (5) lack of sufficient mud weight to prevent hole collapse and gas kicks. The key process in the system is placement of sealant in wellbore cracks to strengthen the wellbore to enable the use of a greater range of mud weights, i.e., a wider MWW. Results from a numerical simulation analysis model are reported. The model is an aid to well planners in their efforts to design wells with (1) fewer casing strings, and (2) small-diameter upper-hole casings. Case histories from around the world indicate that this process can result in substantial cost savings and that it represents a real breakthrough in drilling and completion technology. Improved primary cementing and sustained annular zonal isolation during production are also described. The fracture gradient (FG)-increasing treatments were applied during drilling to prevent lost circulation while cement slurry was being placed in setting casing and liner strings. Production cost savings included shorter periods to start of production, improved well integrity, prevention of annular wellhead pressures, no skin damage in reservoirs, and easy seal removal from producing natural fractures.
Visual performance and biocompatibility of 2 multifocal diffractive IOLs (2007)

Diffractive MIOLs were effective in improving functional capacity for distance and near and provided a good quality of vision due to a significant reduction in spherical aberration, particularly in the Tecnis MIOLs. The higher capsular biocompatibility of the ReSTOR MIOL compared with the Tecnis MIOL could ensure long-term stability.
Storage systems for national information assets (1992)

An industry-led collaborative project, called the National Storage Laboratory (NSL), has been organized to investigate technology for storage systems that will be the future repositories for the national information assets. Lawrence Livermore National Laboratory through its National Energy Research Supercomputer Center (NERSC) is the operational site and the provider of applications. It is anticipated that the integrated testbed system will represent a significant advance in the technology for distributed storage systems capable of handling gigabyte class files at gigabit-per-second data rates. The NSL collaboration is undertaking research in four areas: network-attached storage; multiple, dynamic, distributed storage hierarchies; layered access to storage system services; and storage system management. An overview of the prototype storage system is given. Three application domains have been chosen to test and demonstrate the system's effect on scientific productivity; climatic models, magnetic fusion energy models, and digital imaging. >
Drift study from an air-assisted spray nozzle (2011)

Increased use of pesticides has necessitated development of such pesticide application systems that have maximum effectiveness with minimum losses of pesticides. The drift is one of the losses from a spraying system, which is to be quantified for the development of improved pesticide application equipments. Spray drift tests in field conditions are labour intensive or require very sophisticated instruments for measurements. These depend on wind and climate conditions during the test along with nearby terrain and vegetations etc. Also, it is difficult to assess the influence of different variables on spray drift. An experimental setup was designed and fabricated to quantify the drift from the spray nozzle and to reduce the time as well as resources required for field measurement of drift. This drift represents the maximum possible drift from the nozzle, thus called drift potential. Laboratory experiments were conducted to quantify drift and to determine the effect of nozzle pressure, air speed and forward speed of air-assisted sprayer on spray drift potential. Results showed that drift potential varied from 4.21 % to 46.81 % and it increased with increase in nozzle pressure, air speed and forward speed of the air-assisted sprayer. Among the parameters under study, nozzle pressure influenced the drift potential maximum.
A Hybrid Simulated Annealing And Gradient-Based Algorithm For The Estimation Of Unsaturated Soil Parameters (2007)

Simulation of water flow in the unsaturated zone requires knowledge of hydraulic conductivity
and water content functions. In most applied studies these functions are described by the well-known
van Genuchten constitutive model, which has five independent parameters. Model parameters are usually
determined from laboratory experiments, although often these estimates are non-representative of field
conditions. In recent years, the use of inverse methods in conjunction with field experiments has become
a promising alternative for the accurate estimation of unsaturated soil parameters. Essentially, this procedure
involves the minimization of a cost or objective function that measures the discrepancy between
observed and simulated data. In the present work we estimate the van Genuchten model parameters from
hypothetical drainage experiments using a hybrid optimization strategy based on simulated annealing
and a quasi-Newton method. Drainage experiments are modeled by solving Richards equation with appropriate
initial and boundary conditions. To obtain approximate solutions of Richards equation we use
a Galerkin finite element method. The algorithm behavior and the consequences on the estimated van
Genuchten model parameters using different objective functions are explored. Objective functions are
constructed from two sets of data which are usually obtained on field experiments: pressure head p versus
time measured at different depths and water content  versus depth measured at different times. The
proposed estimation procedure is tested using synthetically generated data. Numerical examples show
that the inverse modeling of drainage experiments using a hybrid simulated annealing and gradient-based
algorithm provides an excellent methodology for an efficient and accurate estimation of unsaturated soil
parameters.
Multiple Vehicles License Plate Tracking and Recognition via Isotropic Dilation (2011)

In this paper, a new algorithm for Automatic License Plate Localisation and Recognition (ALPR) is proposed on the basis of isotropic dilation that can be achieved using the binary image Euclidean distance transform. In a blob analysis problem, any two Region of Interest (RoIs) that is discontinuous are typically treated as separate blobs. However, the proposed algorithm combine with Connected Component Analysis (CCA) are coded to seek for RoI within a certain distance of other RoI to be treated as non-unique. This paper investigates the design and implementation of several pre-processing techniques and isotropic dilation algorithm to classify moving vehicles with different backgrounds and varying angles. A multi-layer feed-forward back-propagation Neural Network is used to train the segmented and refined characters. The results obtained can be used for implementation in the vehicle parking management system.

Action Under Uncertainty (1994)

If one executes a plan, one will need to ‘know whether’ facts tested in it are true, and to ‘know how’ to execute primitive actions in it. It is possible to axiomatize what one needs to know for a plan to be satisfactory. Instead, this paper attempts to explain such knowledge subgoals by showing how they arise from the natural conditions for being a good plan (that it is effective, it terminates and is operational) and from having to act under uncertainty about fact and about meaning.
Sign Language Recognition with the Kinect Sensor Based on Conditional Random Fields (2014)

Sign language is a visual language used by deaf people. One difficulty of sign language recognition is that sign instances of vary in both motion and shape in three-dimensional (3D) space. In this research, we use 3D depth information from hand motions, generated from Microsoft's Kinect sensor and apply a hierarchical conditional random field (CRF) that recognizes hand signs from the hand motions. The proposed method uses a hierarchical CRF to detect candidate segments of signs using hand motions, and then a BoostMap embedding method to verify the hand shapes of the segmented signs. Experiments demonstrated that the proposed method could recognize signs from signed sentence data at a rate of 90.4%.
Glycerol as an agent eliciting small conformational changes in alcohol dehydrogenase. (1975)

Yeast alcohol dehydrogenase is an example of a protein in which the K-m for substrate is substantially decreased by the presence of glycerol. The polyol has the effect at pH 8.0 or above of decreasing K-m and K-s for substrate and of altering both the protein's intrinsic fluorescence and ultraviolet absorption difference spectrum. The relationship between each of thse parameters and glycerol concentration displays a transition at a glycerol concentration of 20%. Circular dichroism values for the enzyme are not affected by glycerol over a large range of concentration and temperature. Treatment of the enzyme with glutaraldehyde results in the formation of cross-linked tetramers, the K-m of which are not altered by the presence of the solvent. The data are interpreted as reflecting a change in the conformation of the protein induced by glycerol.

Personality disorders as disorganisation of attachment and affect regulation (2006)

If personality disorder is no longer to be a diagnosis of exclusion it needs a conceptual framework that fits both the symptoms of the illness and the behavioural problems that constitute its current diagnostic criteria. In this article, we suggest that personality disorder is best understood as disorganisation of the capacity for affect regulation, mediated by early attachments. We present evidence for this argument based on both developmental and neurobiological research.

The Peptidyl-Prolyl Isomerase Activity of SlyD Is Not Required for Maturation of <i>Escherichia coli</i> Hydrogenase (2007)

Escherichia coli SlyD, which is involved in the biosynthesis of the metal cluster in the [NiFe]-hydrogenase enzymes, exhibits several activities including that of a peptidyl-prolyl isomerase (PPIase). Mutations that result in deficient PPIase activity do not produce corresponding decreases in the other activities of SlyD in vitro or in hydrogenase production levels in vivo.
Submerged marine debris detection with autonomous underwater vehicles (2016)

Garbage and debris produced by humans is commonly found in natural underwater environments such as oceans, lakes and rivers. Removal of submerged marine debris is required to prevent threats to marine and human life, and to maintain a sustainable environment. Detecting and mapping debris is hard due to unique difficulties of the underwater environment. In this paper we propose the use of Autonomous Underwater Vehicles to detect submerged marine debris from Forward-Looking Sonar (FLS) imagery. We train a Convolutional Neural Network to classify 96 χ 96 images and use this classifier as an object detector in a sliding window fashion. With this detector we can precisely separate debris from background seafloor. In a dataset of household marine debris captured with an ARIS Explorer 3000 FLS, we obtain 80.8% correct debris detections with a binary detector, and 70.8% with a multiclass detector. Our system can also generate detections for untrained objects, which indicates its good generalization capability. We believe our results point in a direction that Neural Networks combined with FLS form a powerful object detection system for small objects in underwater environments, which is ideal for marine debris.
Analysis and enhancement of human-machine interfaces using a joystick controller (2000)

This article deals with performance evaluation of human operations in point-to-point displacement tasks using a joystick. Analysis of operator outputs during an experimental task revealed a pattern of partially overlapping submovements with predictable velocity characteristics and forms. A velocity-dependent gain control added to the joystick–cursor interface improved performance when compared to a conventional linear transformation. This control algorithm can be recommended for many similar human–machine interfaces. A specific performance evaluation was applied to estimate the characteristics of different remote control designs. This approach can be used for evaluating human–machine systems. © 2000 John Wiley & Sons, Inc.

Constant Addition utilizing Flagged Prefix Structures (2005)

The role of addition and subtraction in digital systems is sometimes complicated due to the arrival of certain operands occurring at different times. For example, floating-point arithmetic typically requires the exponent logic to wait until an output is received from post-normalization. Previously, logic designers have resorted to the use of conditional sum and carry-select adders to make their design efficient. Recently, a new technique has been proposed that utilizes the concept of flagged prefix addition. Flagged prefix addition utilizes the parallel-prefix adder and slightly modifies it to yield a new adder that is capable of adding A+B or A+B+1. Moreover, alterations to the logic can easily be made to allow difference operations to occur as well. The paper presents an extension to flagged prefix addition to allow an arbitrary number to be added to the logic. Results are shown for several designs in AMI C5N 0.5 /spl mu/m technology.
Dietary Supplementation (1997)

In the present study, 6 weight trained men performed nine 15-set sprints on a cycle ergometer on 3 occasions after consuming a 3-day diet that was either high in carbohydrate (CHO), high in protein (Pro), or mixed (Mix). Blood acid-base status was determined at baseline, immediately preexercise, during exercise, and at recovery. There were no significant preexercise changes or differences in either blood lactate or pH; however, [HCO3] was significantly lower with the Pro and Mix diets. With exercise came significant changes in all measures of acid-base status; however, there were no significant differences among the respective diets. At no time did work or peak power output differ significantly across diets. Previous studies have suggested that diet may influence acid-base status and exercise time to exhaustion. The results of this study suggest that while dietary composition can result in slight acid-base changes, these changes do not influence total work and peak power output during repeated bouts of supramaximal exercise.

The Second Food-Production Campaign (2000)

At the start of the Second World War, the free market economy which had regulated agricultural production at macro level as well as allocating resources within the sector, was considered incapable of meeting the challenges of a siege economy. Experiences from the First World War prompted the government to delegate responsibility for food distribution to the Ministry of Food and for controlling food production to the Ministry of Agriculture. It was considered paramount to establish a bureaucratic system of local administration to co-ordinate the farming community because of the ‘innate conservatism of the British farmer’ to agricultural change1 and their opposition to centralized control.2 Sir Reginald Dorman-Smith, Minister of Agriculture, was at pains to emphasize: ‘There will be no farming from Whitehall this time. Instead both farmers’ and allotment holders’ efforts are being organized locally by committees of practical men who know what can and cannot be done in your town or your village.’3 This chapter analyzes the government’s management of the market mechanism and statistics relating to the success of the second food-production campaign in raising total agricultural output. Attention is also devoted to the effectiveness of the WAECs in transforming the agricultural sector and their relationships with farmers, collectively and individually.
Novel Lowpass Harmonic Filters for Satellite Application (2005)

A new class of Iowloss spurious-free lowpass filters in ridged waveguide have been developed for space application.

THE PENETRATION OF ATMOSPHERIC INVERSIONS BY HOT PLUMES (1959)

Abstract Power-station chimneys emit hot gases which may be sufficiently buoyant to penetrate inversions associated with periods of smog. Two notable instances of smog in Great Britain have been examined, applying formulae derived by Sutton and Priestley. A method has been suggested whereby an estimation may be made of the amount of heat required to ensure the penetration of an inversion by a plume.
