Building a Multi-tenant Cloud Service from Legacy Code with Docker Containers

In this paper we address the problem of migrating a legacy Web application to a cloud service. We develop a reusable architectural pattern to do so and validate it with a case study of the Beta release of the IBM Bluemix Workflow Service [1] (herein referred to as the Beta Workflow service). It uses Docker [2] containers and a Cloudant [3] persistence layer to deliver a multi-tenant cloud service by re-using a legacy codebase. We are not aware of any literature that addresses this problem by using containers.The Beta Workflow service provides a scalable, stateful, highly available engine to compose services with REST APIs. The composition is modeled as a graph but authored in a Javascript-based domain specific language that specifies a set of activities and control flow links among these activities. The primitive activities in the language can be used to respond to HTTP REST requests, invoke services with REST APIs, and execute Javascript code to, among other uses, extract and construct the data inputs and outputs to external services, and make calls to these services.Examples of workflows that have been built using the service include distributing surveys and coupons to customers of a retail store [1], the management of sales requests between a salesperson and their regional managers, managing the staged deployment of different versions of an application, and the coordinated transfer of jobs among case workers.
The Artificial Life Roots of Artificial Intelligence

Behavior-oriented Artificial Intelligence (AI) is a scientific discipline that studies how behavior of agents emerges and becomes intelligent and adaptive. Success of the field is defined in terms of success in building physical agents that are capable of maximizing their own self-preservation in interaction with a dynamically changing environment. The paper addresses this Artificial Life route toward AI and reviews some of the results obtained so far.
Classification of healthcare data using genetic fuzzy logic system and wavelets

Healthcare plays an important role in promoting the general health and well-being of people around the world. The difficulty in healthcare data classification arises from the uncertainty and the high-dimensional nature of the medical data collected. This paper proposes an integration of fuzzy standard additive model (SAM) with genetic algorithm (GA), called GSAM, to deal with uncertainty and computational challenges. GSAM learning process comprises three continual steps: rule initialization by unsupervised learning using the adaptive vector quantization clustering, evolutionary rule optimization by GA and parameter tuning by the gradient descent supervised learning. Wavelet transformation is employed to extract discriminative features for high-dimensional datasets. GSAM becomes highly capable when deployed with small number of wavelet features as its computational burden is remarkably reduced. The proposed method is evaluated using two frequently-used medical datasets: the Wisconsin breast cancer and Cleveland heart disease from the UCI Repository for machine learning. Experiments are organized with a five-fold cross validation and performance of classification techniques are measured by a number of important metrics: accuracy, F-measure, mutual information and area under the receiver operating characteristic curve. Results demonstrate the superiority of the GSAM compared to other machine learning methods including probabilistic neural network, support vector machine, fuzzy ARTMAP, and adaptive neuro-fuzzy inference system. The proposed approach is thus helpful as a decision support system for medical practitioners in the healthcare practice. 2014 Elsevier Ltd. All rights reserved.
Classification of canal control algorithms

Different control algorithms for the regulation of irrigation canals have been developed and applied throughout the world. Each of them can be characterized according to several criteria, among which are: the considered variables (controlled, measured, control action variables), the logic of control (type and direction), and the design technique. The following text presents definitions of these terms and a classification of the algorithms detailed in the literature. To summarize and compare algorithms, a structured table of the main published canal control algorithms is presented.
Internet of Things Based Intelligent Street Lighting System for Smart City

This project aims for designing and executing the advanced development in embedded systems for energy saving of street lights. Currently we have a manual system where the street lights will be switched ON in the evening before the sunsets and they are switched OFF in the next day morning after there is sufficient light on the outside[1]. But the actual timing for these lights to be switched ON is when there is absolute darkness. With this, the power will be wasted up to some extent. This project gives solution for electrical power wastage [2]. Also the manual operation of the lighting system is completely eliminated. The proposed system provide a solution for energy saving. This is achieved by sensing and approaching a vehicle using an IR transmitter and IR Receiver couple. Upon sensing the movement the sensor transmit the data to the microcontroller which furthermore the Light to switch ON [4]. Similarly as soon as the vehicle or an obstacle goes away the Light gets switched OFF as the sensor sense any object at the same time the status(ON/OFF) of the street light can be accessed from anywhere and anytime through internet. This project is implemented with smart embedded system which controls the street lights based on detection of vehicles or any other obstacles on the street .Whenever the obstacle is detected on the street within the specified time the light will get automatically ON/OFF according to the obstacle detection and the same information can be accessed through internet. The real time information of the street light(ON/OFF Status) can be accessed from anytime, anywhere through internet.
Nanoscale light–matter interactions in atomic cladding waveguides

Alkali vapours, such as rubidium, are being used extensively in several important fields of research such as slow and stored light nonlinear optics quantum computation, atomic clocks and magnetometers. Recently, there is a growing effort towards miniaturizing traditional centimetre-size vapour cells. Owing to the significant reduction in device dimensions, light-matter interactions are greatly enhanced, enabling new functionalities due to the low power threshold needed for nonlinear interactions. Here, taking advantage of the mature platform of silicon photonics, we construct an efficient and flexible platform for tailored light-vapour interactions on a chip. Specifically, we demonstrate light-matter interactions in an atomic cladding waveguide, consisting of a silicon nitride nano-waveguide core with a rubidium vapour cladding. We observe the efficient interaction of the electromagnetic guided mode with the rubidium cladding and show that due to the high confinement of the optical mode, the rubidium absorption saturates at powers in the nanowatt regime.
Heart failure assessment at the community pharmacy level: a feasibility pilot study.

BACKGROUND
A key element missing in disease-management programs for heart failure (HF) is participation of the community pharmacist. The purpose of this study is to determine if a simple and efficient clinical tool will allow community pharmacists to identify patients at risk for worsening HF.


DESIGN
The One Minute Clinic for Heart Failure (TOM-C HF) was developed as a simple six-item symptom screening tool to be used during routine patient/customer interactions.


SETTING
Ten community pharmacies located in the upper Midwest.


PATIENTS
Self-identified HF patients.


RESULTS
121 unique patients were evaluated over a 12-month period. The application of this clinical tool took between 1 and 5 minutes in over 80% of the interactions. Seventy-five patients (62%) had one or more signs or symptoms of worsening HF. The most common symptoms detected included edema (39%) and increased shortness of breath (17%). Self-reported weight gain of more than 5 pounds was seen in 19% of patients.


CONCLUSION
The TOM-C HF tool was used to identify patients in a time-efficient manner in the community pharmacy setting who appear to be developing worsening HF. Inclusion of the community pharmacists as an early screen for HF decompensation may be an important link in disease-management programs to help reduce hospital readmission rates.
TDR Measurement Method for Voltage-Dependent Capacitance of Power Devices and Components

The measurement of circuit parasitic parameters and the evaluation of equivalent circuit models are both necessary techniques for noise analysis and the circuit design of high-speed power electronics circuits. Recently, time-domain reflectometry (TDR) has emerged as a technique for measuring circuit parameters. This paper proposes a TDR method for measuring the voltage- dependent capacitance of power devices and passive components. This method can be used to measure the capacitance on any dc bias voltage. The Coss value of MOSFETs with VDS = 0-350 V, the anode-cathode capacitance under reverse bias condition on SiC diodes, and voltage-dependent capacitances of ceramic capacitors were measured in experiments.
A micromachining process for die-scale pattern transfer in ceramics and its application to bulk piezoelectric actuators

This paper reports on a batch mode planar pattern transfer process for bulk ceramics, glass, and other hard, brittle, nonconductive materials suitable for micromachined transducers and packages. The process is named LEEDUS, as it combines lithography, electroplating, batch mode micro electro-discharge machining (/spl mu/EDM) and batch mode micro ultrasonic machining (/spl mu/USM). An electroplating mold is first created on a silicon or metal wafer using standard lithography, then using the electroplated pattern as an electrode to /spl mu/EDM a hard metal (stainless steel or WC/Co) tool, which is finally used in the /spl mu/USM of the ceramic substrate. A related process (SEDUS) uses serial /spl mu/EDM and omits lithography for rapid prototyping of simple patterns. Feature sizes of 25 /spl mu/m within a 4.5/spl times/4.5 mm/sup 2/ die have been micromachined on glass-mica (Macor) ceramic plates with 34 /spl mu/m depth. The ultrasonic step achieves 18 /spl mu/m/min. machining rate, with a tool wear ratio of less than 6% for the stainless steel microtool. Other process characteristics are also described. As a demonstration, octagonal and circular spiral shaped in-plane actuators were fabricated from bulk lead zirconate titanate (PZT) plate using the LEEDUS/SEDUS process. A device of 20 /spl mu/m thickness and 450 /spl mu/m/spl times/420 /spl mu/m footprint produces a displacement of /spl ap/2/spl mu/m at 40 V.
Stress, coping and burn-out in nursing students.

AIM
To explore the relationship between sources of stress and psychological burn-out and to consider the moderating and mediating role played sources of stress and different coping resources on burn-out.


BACKGROUND
Most research exploring sources of stress and coping in nursing students construes stress as psychological distress. Little research has considered those sources of stress likely to enhance well-being and, by implication, learning.


METHOD
A questionnaire was administered to 171 final year nursing students. Questions were asked which measured sources of stress when rated as likely to contribute to distress (a hassle) and rated as likely to help one achieve (an uplift). Support, control, self-efficacy and coping style were also measured, along with their potential moderating and mediating effect on burn-out.


FINDINGS
The sources of stress likely to lead to distress were more often predictors of well-being than sources of stress likely to lead to positive, eustress states. However, placement experience was an important source of stress likely to lead to eustress. Self-efficacy, dispositional control and support were other important predictors. Avoidance coping was the strongest predictor of burn-out and, even if used only occasionally, it can have an adverse effect on burn-out. Initiatives to promote support and self-efficacy are likely to have the more immediate benefits in enhancing student well-being.


CONCLUSION
Nurse educators need to consider how course experiences contribute not just to potential distress but to eustress. How educators interact with their students and how they give feedback offers important opportunities to promote self-efficacy and provide valuable support. Peer support is a critical coping resource and can be bolstered through induction and through learning and teaching initiatives.
OSCILLATION CRITERIA FOR FORCED SECOND-ORDER MIXED TYPE QUASILINEAR DELAY DIFFERENTIAL EQUATIONS

This article presents new oscillation criteria for the second-order delay differential equation (p(t)(x′(t))α)′ + q(t)x(t− τ) + n X i=1 qi(t)x αi (t− τ) = e(t) where τ ≥ 0, p(t) ∈ C1[0,∞), q(t), qi(t), e(t) ∈ C[0,∞), p(t) > 0, α1 > · · · > αm > α > αm+1 > · · · > αn > 0 (n > m ≥ 1), α1, . . . , αn and α are ratio of odd positive integers. Without assuming that q(t), qi(t) and e(t) are nonnegative, the results in [6, 8] have been extended and a mistake in the proof of the results in [3] is corrected.
A Bayesian Method for Transformer Life Estimation Using Perks' Hazard Function

This paper introduces PJM Interconnection's new method to model and predict transformers' service lives. A simplified Perks' equation is used to model the hazard rates, which will be used synonymously with retirement rates in this paper, of transmission transformers. A Bayesian Method is used to model the uncertainty in the three parameters of Perks' equation. This method is different from the traditional Iowa Curve method in that: 1) it gives a continuous family of transformer life distributions as well as the extinction likelihoods, rather than a limited number of distribution patterns and 2) a closed-form distribution can also be deduced with only three parameters, which can assume all the three distribution patterns of Iowa Curves: right, left, and symmetrically modal. The method has been successfully applied to the statistics on hundreds of large electric transformers in PJM. Example problems are provided and solved with this new method
Market structure , liberalization and performance in the Malawian banking industry

Financial sector reforms in Malawi began in the late 1980s as a continuation of structural adjustment programmes sponsored by the International Monetary Fund and the World Bank. Prior to liberalization, the financial system was highly repressed, with heavy government intervention in the banking sector through credit and interest rate controls. Furthermore, the banking sector was highly oligopolistic: two banks dominated commercial banking activities. Financial sector reforms led to the removal of credit ceilings and interest rate controls and opened the banking system to new competition. This study examines the effect of financial sector reforms on market structure, financial intermediation, savings mobilization and commercial bank profitability in the Malawian banking industry. The evidence in this study shows that some signs of financial repression still exist, although some positive developments have taken place. The results show that financial liberalization has significantly increased financial depth and savings mobilization, increased credit to the manufacturing sector, and reduced the monopoly power in the Malawian banking system. However, real interest rates have fallen, intermediation margins have increased, credit to the public sector has increased and that to the private sector has fallen. Using the market structure–performance hypothesis, the study finds a significant relationship between monopoly power and commercial bank profitability, but rejects the efficient market hypothesis. Thus, although interest rates were under control for most of the study period, other bank services that generate income for commercial banks were subject to monopoly power abuse.
Patients’ knowledge of potential pelvic floor changes associated with pregnancy and delivery

Physicians cite pelvic floor injury as a major reason for Cesarean section as their personal preferred delivery mode. This study was undertaken to determine whether patients receive information about possible pelvic floor complications of pregnancy/delivery. Day 1 post-partum women completed a 52-item questionnaire assessing information given during routine antenatal care. Pelvic floor and general questions were intermixed. Of the 232 patients, the mean age was 26.9 years, with 59.5% white, 32.8% African-American and 7.7% other. Most (84.5%) had at least grade 12 education. The following percentage of patients reported receiving no information about: Kegel exercises 46.1%; episiotomy 51.3%; urinary incontinence 46.6%; fecal incontinence 80.6%; change in vaginal caliber 72.8%; neuropathy 84.9%. Counseling on all of these issues occurred significantly less frequently than education on general pregnancy topics. Our results suggest that knowledge and instruction of pelvic floor risks is very much lacking and provide us with an impetus to develop educational tools.
Reconstruction of microtia.

SUMMARY
The reconstruction of microtia continues to represent one of the more challenging plastic surgery procedures. The limitations of the reconstruction are partly inherent in the soft-tissue deficiencies present in increasing degrees from large conchal remnant microtia, to lobular microtia, to the displaced remnant in auricular dystopia, and partly because of the high level of technical expertise required. After a brief review of the history of ear reconstruction in general and microtia specifically, issues related to the transition in the popularity from techniques involving three or more stages (Tanzer and Brent) to the current popularity of two-stage procedures (Nagata, Firmin, and Park) are discussed in detail. Each of the popular procedures is viewed in relation to timing of the reconstruction, procedure planning, and how both the soft tissues and framework construction are handled, in each of the stages. The most significant differences include whether the autogenous cartilage framework is constructed with or without the tragal construct (for the lobular-type microtia), whether or not the lobule is rotated in the first-stage reconstruction, whether an additional cartilage block is placed behind the framework for added ear projection, and how that added block is covered (choice of fascia flap and skin graft). Each of the techniques has to be varied in reconstruction of auricular dystopia in light of the associated skeletal and soft-tissue hypoplasia. In this article, the author demonstrates that although there may be significant advantages to the two-stage reconstructions of Nagata and Firmin, some may feel that the larger amount of cartilage harvested, the later optimal age for beginning the reconstruction, the additional scalp scars engendered by using the temporoparietal fascia flap in the second-stage elevation of the framework, and even the exchange of lobule tissue (and ability to later pierce ears) to obtain better coverage of the concha and tragus are unacceptable. Having gained experience with each of the varied approaches and having modified them when unusual variations in deformities have required it, the author discusses his current preferences. Clearly, this author feels that there may be significant advantages to delaying the reconstruction to age 10 years or older, yet experience gained over the past 25 years would seem to indicate that as in all other aspects of plastic and reconstructive surgery one must never be wed to a single approach, and experience and flexibility are essential in obtaining the optimal outcome in all variations of the deformity.

Empathy among Medical Students: Is There a Relation with Quality of Life and Burnout?

BACKGROUND
We aimed to assess medical students' empathy and its associations with gender, stage of medical school, quality of life and burnout.


METHOD
A cross-sectional, multi-centric (22 medical schools) study that employed online, validated, self-reported questionnaires on empathy (Interpersonal Reactivity Index), quality of life (The World Health Organization Quality of Life Assessment) and burnout (the Maslach Burnout Inventory) in a random sample of medical students.


RESULTS
Out of a total of 1,650 randomly selected students, 1,350 (81.8%) completed all of the questionnaires. Female students exhibited higher dispositional empathic concern and experienced more personal distress than their male counterparts (p<0.05; d ≥ 0.5). There were minor differences in the empathic dispositions of students in different stages of their medical training (p<0.05; f<0.25). Female students had slightly lower scores for physical and psychological quality of life than male students (p<0.05; d<0.5). Female students scored higher on emotional exhaustion and lower on depersonalization than male students (p<0.001; d<0.5). Students in their final stage of medical school had slightly higher scores for emotional exhaustion, depersonalization and personal accomplishment (p<0.05; f<0.25). Gender (β = 0.27; p<0.001) and perspective taking (β = 0.30; p<0.001) were significant predictors of empathic concern scores. Depersonalization was associated with lower empathic concern (β =  -0.18) and perspective taking (β =  -0.14) (p<0.001). Personal accomplishment was associated with higher perspective taking (β = 0.21; p<0.001) and lower personal distress (β =  -0.26; p<0.001) scores.


CONCLUSIONS
Female students had higher empathic concern and personal distress dispositions. The differences in the empathy scores of students in different stages of medical school were small. Among all of the studied variables, personal accomplishment held the most important association with decreasing personal distress and was also a predicting variable for perspective taking.
A compiler for linear algebra operations

In this paper we present a compiler that translates arithmetic expressions containing matrices to efficient sequences of calls to basic linear algebra kernels.
Partition Search

We introduce a new form of game search called partition search that incorporates dependency analysis, allowing substantial reductions in the portion of the tree that needs to be expanded. Both theoretical results and experimental data are presented. For the game of bridge, partition search provides approximately as much of an improvement over existing methods as a-0 pruning provides over minimax.
