Operationalising CMMI: integrating CMMI and CoBIT perspective

– The use of capability maturity model integration (CMMI) on its own can be problematic for the organisation because it does not provide a roadmap to implementation or identification of key process improvement areas, but instead only provides the goals for each level of implementation. Addition of another framework such as control objectives for information and related technology (CoBIT) can add the required operational data, but poses some unique challenges for implementation. However, the integration of Information Technology Infrastructure Library (ITIL), CoBIT, and ISO/IEC 22007 provides a roadmap to the integration of CMMI and CoBIT. The purpose of this paper is to discuss this co‐implementation and integration of the two frameworks, as well as the underlying framework of a new proposed integration model. , – A literature review approach is used to address issues that have evolved from the empirical literature regarding the integration of CMMI and ITIL with other standards and determining whether this approach can be applied to the integration of CMMI and CoBIT as well. This literature review also provides insight into roadblocks to the implementation and structural improvements for CMMI. , – The literature review demonstrated that the integration of CMMI and CoBIT could potentially be performed using the same techniques used in integrating ITIL and CoBIT, which provides a valuable guideline for further research into this area. However, further work will be required in order to determine the specifics of integration. , – The paper adds to the existing literature by discussing the integration of CMMI and CoBIT and examining how these two frameworks can work together in order to create the basis for a new integration model.
Comprehensive evaluation of natural enemy dominant species of
 Breuipalpus oboyats
 in tea garden in autumn and winter

The purpose of this study was to comprehensively evaluate the dominant natural enemies of Breuipalpus oboyats in autumn and winter tea gardens. The relationship between natural enemies and B.oboyats in time and space was studied by niche analysis and geostatistics combined with angular cosine coefficient method. According to the comparison of the sum of closeness index, it is found that the top three natural enemies (from large to small) that are most closely related to B.oboyats in the “Nongkangzao” tea garden are Plexippus paykulli, Clubiona japonicola, and Xysticus ephippiafus; “Pingyangtezao” tea garden are X.ephippiafus, Plexippus setipet, and Oxyopes sertatus. In front of the two tea gardens, one of the three natural enemies is the same. The evaluation of the comprehensive closeness index of the two tea gardens shows that the top three natural enemies most closely related to B.oboyats are X.ephippiafus, P.paykulli, and O.sertatus. X.ephippiafus is the most important natural enemy of B.oboyats in tea gardens in autumn and winter; the dominant natural enemies of the same pests in different varieties of tea gardens in the same area are often different.
An infrastructure for social software

In a virtual world, as DVE (distributed virtual environment) applications are often called, logistic support must be supplied by software. As the range of DVE applications expands, they will need software support of a kind rarely envisioned by previous generations of programmers. A new breed of programs is required: social software. The overriding point of social software is not simulation but conversation. Its applications are not substitutes for real-world interaction, but extensions of it. Its "worlds" are not virtual in the customary sense; they are real media for meeting others online. Designers of social software are less concerned with how well their on-screen objects mimic real-world objects than with how well they connect their users to each other. Simulation environments can be thought of as being like the "preview" mode of a word processor, designed to match the look of a printed document. Social environments, by comparison, are like hypertext, opening up avenues of communication that were unforeseen in the media that preceded them. The disparate programs meant for virtual worlds will need a common platform to underpin widespread social interaction.
Study of trend analysis and extreme events of temperature over Varanasi during summer monsoon season

Temporal changes in the monthly and seasonal temperatures over Varanasi District were analysed, based on the 40 years of time series databases of daily temperatures from 1971 to 2010. The temperature changes during the two tricades of 1971-2000 and 1981-2010 and also for four decades starting from 1971 to 2010 were investigated and both the Mann–Kendall (MK) trend test and simple linear regression analyses were employed to detect trends in the mean maximum temperatures and mean minimum temperatures. Various extreme temperatures criteria, as well as their corresponding frequencies, were chosen to explore the trends of extreme climate change over Varanasi. The warming of seasonal mean temperature is mainly attributed to changes in the minimum temperature, particularly during the last three decades. A pre-monsoon cooling and its association with increase in heat wave days suggest that, alongwith large-scale circulation, regional and local factors may have played a vital role in influencing the observed climate in the studied area.
Design of Drawbar Transducers for Measuring Dynamic Forces

ABSTRACT ACCURACY of static calibration for measuring dynamic forces was shown to be a function of the frequency ratio (forcing function frequency/transducer natural frequency). Static calibration used for measuring dynamic draft forces with steel drawbars was shown to have errors less than 1% for frequency ratios less than 0.1. Two analytical methods (lumped mass and wave propagation) for estimating transducer lowest natural frequency were discussed. Accurate reconstruction of dynamic force was shown to depend on the ratio of sampling frequency to the highest frequency present in the dynamic force. Guidelines indicate the dynamic force should be sampled at a frequency six to ten times higher than the highest frequency present in the dynamic force.
Determination of the parameters of a statistical ensemble of micro-objects in a waveguide optical microscope

The inverse problem was made with the use of the Tikhonov's regularization and analytical extension of power spectral density. The possibility to achieve a superresolution was demonstrated.
Correlation between Physiological Parameters of Automobile Drivers and Traffic Conditions

Driving a car is a complex cognitive process in which even a small lack of attention can have disastrous consequences. Various studies have been conducted in the past focusing mainly on the driver’s internal state (physical and emotional) like drowsiness, fatigue and mental stress as these are the major cause behind large number of fatal road accidents worldwide. The studies show that in most of the automobile driver’s Galvanic Skin Response (GSR) and Heart Rate (HR) parameters are more closely related to drivers stress level. The authors accessed raw physiological signals available at PHYSIONET website and then extract useful statistical features from these. The most relevant features were then selected using open source software. Removal of irrelevant features makes the stress detection model much faster and helps to gain a deeper insight into the underlying processes of stress detection and classification. Correlation analysis on the selected features showed that Mean HR and Mean Hand GSR are the two statistical features that have a very strong correlation with changing traffic conditions.
LLC resonant converter for front end DC/DC conversion

A new LLC resonant converter is proposed for front end DC/DC conversion in a distributed power system. Three advantages are achieved with this resonant converter. First, ZVS turn on and low turn off current of MOSFETs are achieved. The switching loss is reduced so we can operate the converter at higher switching frequency. The second advantage is that with this topology, we can optimize the converter at high input voltage. Finally, with this topology, we can eliminate the secondary filter inductor, so the voltage stress on the secondary rectifier will be limited to two times the output voltage, better rectifier diodes can be used and secondary conduction loss can be reduced. The converter utilizes leakage and magnetizing inductance of a transformer. With magnetic integration concept, all the magnetic components can be built in one magnetic core. The operation and characteristic of this converter is introduced and efficiency comparison between this converter and a conventional PWM converter is given which shows a great improvement by using this topology.

Compact waterjets for high-speed ships

Abstract The article describes the development and validation of a compact waterjet propulsion system for high-speed vessels. The development was conducted in four discrete phases over a period of 4 years: Phase 1 involved studies of pump-type options for compact units; Phase 2 used advanced Computational Fluid Dynamics (CFD) to design the preferred pump type for a high-speed ship design; Phase 3 involved the manufacture and performance/cavitation testing of a model of the pump designed in Phase 2; and Phase 4 involved the construction and testing, in a towing tank, of a self-propelled model to determine the critical interaction effects between the hull and the waterjet inlet. Following an introduction that serves to define the challenge, the article discusses what is good and not so good about marine waterjet propulsion. It then describes the design approach, the design tools used, the testing procedures, and the validation comparison of CFD predicted and model test results. In addition, it describes the whole-ship impact of using these advanced pumps in terms of the significant improvements possible in ship speed, range or payload. The overall program was considered to be an outstanding success with the potential of having major benefits to future high-speed ships.
Evidence of Swim secretion and association with extracellular matrix in the Drosophila embryo.

Secreted wingless-interacting protein (Swim) is the Drosophila ortholog gene of the mammalian Tubulointerstitial Nephritis Antigen Like 1 (TINAGL1), known also as lipocalin-7 (LCN7), or adrenocortical zonation factor 1 (AZ-1). Swim and TINAGL1 proteins share a significant homology, including the somatomedin B and the predictive inactive C1 cysteine peptidase domains. In mammals, both TINAGL1 and its closely related homolog TINAG have been identified in basement membranes, where they may function as modulators of integrin-mediated adhesion. In Drosophila, Swim was initially identified in the eggshell matrix and subsequently was detected in the culture medium of S2 cells. Further biochemical analysis indicated that Swim binds to wingless (wg) in a lipid-dependent manner. This observation together with RNAiknockdown studies suggested that Swim is an essential cofactor of wg-signalling. However, recent elegant genetic studies ruled out the possibility that Swim is required alone to facilitate wgsignalling in Drosophila, because flies without Swim are viable and fertile. Here, we use the UAS/Gal4 expression system together with confocal imaging to analyze the in vivo localization of a chimeric Swim-GFP in the developing Drosophila embryo. Our data fully support the notion that Swim is an extracellular matrix component that upon ectopic expression is secreted and preferentially associates with the basement membranes of various organs and with the specialized tendon matrix at the muscle attachment sites (MAS). Interestingly, the accumulation of Swim at the MAS does not require integrins. In conclusion, Swim is an extracellular matrix component, and it is possible that Swim exhibits overlapping functions in concert with other undefined components.
About the beginnings of wireless

Many scientists and engineers contributed – more or less successfully – to the development of radio and wireless. This historical survey describes briefly the projects realized more than a century ago by some of them, at the early beginnings of wireless. It is hoped, in this manner, to draw attention to the unknown or forgotten researchers who built up the considerable body of knowledge that led to Marconi's remarkable achievements.
Toward real-time endocardial boundary detection from intracardiac echocardiographic images: a comparative study

In this paper a novel method is proposed for live endocardial boundary identification. The goal is to achieve an optimal solution to the problem of real-time automatic detection and tracking of endocardial border in ultrasonic image sequences acquired through Intracardiac Echocardiography (ICE). Border identification of 2D ultrasonic images, which normally consists of a number of stages namely preprocessing, segmentation, detection and visualization of the border, is a cumbersome task. ICE's potential in guidance of minimally invasive interventions requires online boundary detection of its inherently less speckled images. Numerous studies have addressed this issue in echographic images by proposing various methods applicable at each stage. With this repository of methods available, a comparative study is performed on single-image segmentation approaches. An algorithm based on order-statistics operators is proposed to achieve fast border delineation in a sequence of images. This method can outperform other approaches in terms of time and robustness, and does not require user interaction.
RESILIENT MODULUS OF FREEZE-THAW AFFECTED GRANULAR SOILS FOR PAVEMENT DESIGN AND EVALUATION. PART 1. LABORATORY TESTS ON SOILS FROM WINCHENDON, MASSACHUSETTS, TEST SECTIONS

This work is the first of a series of four reports about laboratory and field testing of various granular road and airfield subgrades. This report details the acquisition, testing and analysis of six soils from a test site in Winchendon, Massachusetts. Repeat load triaxial tests were done on frozen and thawed soils to characterize the variations in their resilient properties throughout the seasons. Linear regression yielded empirical equations relating the resilient modulus to applied stress, unfrozen water content (for frozen soils), moisture tension (for thawed soils) and density. Equipment and test procedures (given in detail) were developed that allowed simulation in the laboratory of the gradual recovery of stiffness that occurs in the field after thawing. The resilient moduli were strongly dependent on soil state, dropping at least two orders of magnitude upon thawing. For all soils the moduli increased with increasing confining stress, generally decreased with increasing principal stress ratio, and increased with increasing moisture tension levels. The resilent moduli increased by a factor of approximately two as the materials recovered from the effects of a freeze-thaw cycle. This recovery process is well modeled as a function of the soil moisture tension level. The stress sensitivity did not appear to be a function of the soil moisture tension level. The report also includes tabulations of all the repeated load triaxial test data.
Registration based on Euclidean reconstruction and natural features tracking for augmented reality systems

Purpose – The purpose of this paper is to propose a novel registration method using Euclidean reconstruction and natural features tracking for AR‐based assembly guidance systems.Design/methodology/approach – The method operates in two steps: offline Euclidean reconstruction and online tracking. Offline stage involves obtaining the structure of scene using Euclidean reconstruction technique. The classification trees are constructed using affine transform for online initialization. In tracking, the classification‐based wide baseline matching strategy and Td,d test are used to get a fast and accurate initialization for the first frame after which a modified optical flow tracker is used to fulfill the task of feature tracking in the real‐time video sequences. The four specified points are transferred to the current image to compute the registration matrix for augmentation.Findings – Firstly, Euclidean reconstruction was used instead of projective reconstruction to get the projections of predefined features.

Design of a vision-based autonomous path-tracking control system and experimental validation

Abstract This paper describes an automated path-tracking system using a vision sensor. A lateral control law for path tracking is especially emphasized which is developed by using back-stepping control design methodology. To establish the proposed control system, the lateral offset to the reference path, the heading angle of the vehicle relative to the tangent line to the path, and the path curvature are required. Those inputs to the controller have been calculated through a Kalman filter which is frequently utilized for the purpose. Lane mark detection has been achieved in an electronic control unit platform with a vision sensor. The yaw rate and side-slip angle also needed in the controller are estimated by the observer. To demonstrate the performances of the proposed controller at different speeds, an experiment has been conducted on a proving ground having a straight section and a curved section with a curvature of about 260m.
Run-off and Soil Loss Estimation Using Numerical Approach in Hard Rock Terrain.

The present study reveals the potential run-off estimation, soil erosion and scope of groundwater recharge in the Bundelkhand region in the state of U.P. , India. The estimation of run-off and soil erosion have provided a platform to evaluate the realistic potential for water conservation in the study area. The study area is characterized by occurrence of mild to severe drought conditions with significant run-off and poor infiltration. Geomorphological factors such as land use changes, slope, and nature of soil affect the run-off rate and discharge significantly. Soil map and rainfall data for the study area were acquired to evaluate the hydrological soil group (HSG) and antecedent moisture condition (AMC) respectively. Soil Conservation Services and Curve Number (SCS-CN) method has been used to calculate the run-off volume at the point where river/streams join together while soil loss has been calculated using revised universal soil loss equation of RUSLE model with the input of spatial data sets such as soil texture, rainfall, topography etc. The maximum run-off (355mm) has been estimated in watershed-1 during 2016 and minimum (1 mm) in watershed-4 respectively. The estimated run-off varies from 5.5% to 28% of the total rainfall in the study area, while soil loss is maximum (2.1x106 ton/ha) in the watershed-1. It is a fact that soil loss is in conformity with run-off. This finding provides the roadmap for the selection of suitable artificial recharge structures to augment the groundwater in the study area.
10.3.2 The Development of an Architecture Framework for Systems Engineering Process Simulators

Systems engineering process simulators can help users to explore risks and evaluate the consequences of various project, process, and organization decisions. These types of simulators can incorporate the complex system dynamics associated with various concerns and include critical factors, their associated relationships, and corresponding effects, allowing one to reason and explore various decision options. Simulators can also help educate current and new engineers to understand the multi‐faceted issues related to systems engineering projects and processes. In support of the development of these types of simulators, this paper discusses the need for an architecture framework for systems engineering simulators. An architecture framework is proposed as an enabler to assist in the development of systems engineering process simulators.
Exercise adherence‐related perceptual responses to low‐load blood flow restriction resistance exercise in young adults: A pilot study

Resistance exercise (RE) with blood flow restriction (BFR) is recognized as a beneficial strategy in increasing skeletal muscle mass and strength. However, the effects of BFR on changes in perceptual parameters, particularly those related to exercise adherence, induced by RE are not completely understood. In this study, we examined the exercise adherence‐related perceptual responses to low‐load BFR‐RE. Sixteen young males performed both BFR and non‐BFR (NBFR) sessions in a crossover design. The bilateral knee extensor low‐load RE was performed with a standard BFR‐RE protocol, consisting of four sets (total 75 repetitions), using 20% of one‐repetition maximum. BFR‐RE was performed with 200 mmHg pressure cuffs placed around the proximal region of the thighs. NBFR‐RE was performed without pressure cuffs. The ratings of perceived exertion and leg discomfort measured using the Borg's Scales were higher for BFR‐RE session than for NBFR‐RE session (both p < 0.001 for interaction effect). The Feeling Scale‐measured affect and Task Motivation Scale‐measured task motivation were lower for BFR‐RE session than for NBFR‐RE session (both p < 0.05 for interaction effect); by contrast, the Numerical Rating Scale‐measured perceived pain was higher for BFR‐RE session than for NBFR‐RE session (p < 0.001 for interaction effect). The Physical Activity Enjoyment Scale‐measured enjoyment immediately after RE was lower with BFR than with NBFR (p < 0.001). These findings suggest that BFR exacerbates the exercise adherence‐related perceptual responses to low‐load RE in young males. Therefore, further studies are needed to develop effective strategies that minimize the BFR‐RE‐induced negative effects on perceptual responses.
