How do agile practices support automotive SPICE compliance?

In the automotive domain, Automotive SPICE® is a common requirement for software and system development. Most automotive companies face the problem of complying with this model, especially, when dealing with agile development in order to benefit from advantages, such as higher customer collaboration or faster development. This paper describes the evaluation of how agile practices support Automotive SPICE requirements, based on literature reviews and expert opinion and including 772 mappings. 103 of 155 agile practices including Scrum and XP were used to cover 173 of 185 Automotive SPICE requirements (base practices and work products). Most Automotive SPICE base practices are supported (96%), while there is less support for work products (87%). The results are coherent with existing more high-level mappings but show more details. These results enable companies to benefit from agile without compromising Automotive SPICE conformity.

Influence of teacher empowerment on teachers ’ organizational commitment , professional commitment and organizational citizenship behavior in schools

The present study focuses on the relationship between teacher empowerment and teachers’ organizational commitment, professional commitment (PC) and organizational citizenship behavior (OCB). It examines which subscales of teacher empowerment can best predict these outcomes. The data were collected through a questionnaire returned by a sample of 983 teachers in Israeli middle and high schools. Pearson correlations and multiple regression analyses indicated that teachers’ perceptions of their level of empowerment are significantly related to their feelings of commitment to the organization and to the profession, and to their OCBs. Among the six subscales of empowerment, professional growth, status and self-efficacy were significant predictors of organizational and PC, while decisionmaking, self-efficacy, and status were significant predictors of OCB. Practical implications of the study are discussed in relation to teachers, principals and policy-makers. r 2004 Elsevier Ltd. All rights reserved.
Peripheral splittings of groups

We define the notion of a “peripheral splitting” of a group. This is essentially a representation of the group as the fundamental group of a bipartite graph of groups, where all the vertex groups of one colour are held fixed—the “peripheral subgroups”. We develop the theory of such splittings and prove an accessibility result. The theory mainly applies to relatively hyperbolic groups with connected boundary, where the peripheral subgroups are precisely the maximal parabolic subgroups. We show that if such a group admits a non-trivial peripheral splitting, then its boundary has a global cut point. Moreover, the non-peripheral vertex groups of such a splitting are themselves relatively hyperbolic. These results, together with results from elsewhere, show that under modest constraints on the peripheral subgroups, the boundary of a relatively hyperbolic group is locally connected if it is connected. In retrospect, one further deduces that the set of global cut points in such a boundary has a simplicial treelike structure.
Optimization of Magnetic Circuit for Brushless Doubly Fed Machines

This paper presents an optimized design method for the magnetic circuit of brushless doubly fed machines (BDFMs). The BDFM is an attractive electrical machine, particularly for wind power applications, as a replacement for doubly fed slip-ring generators. This study shows that the conventional design methods for the BDFM stator and rotor back iron can be modified, leading to a lighter and smaller machine. The proposed design concepts are supported by analytical methods, and their practicality is verified using two-dimensional finite-element modeling and analysis. Two BDFMs with frame sizes D180 and D400 are considered in this study.
Data Reduction and Noise Filtering for Predicting Times Series

In this paper we introduce a modification of the real discrete Fourier transform and its inverse transform to filter noise and perform reduction on the data whilst preserving the trend of global moving of time series. The transformed data is still in the same time domain as the original data, and can therefore be directly used by any other mining algorithms. We also present a classification algorithm MinCov in this paper. Given a new data tuple, it provides values for each class that measures the likelihood of the tuple belonging to that class. The experimental results show that the MinCov algorithm is comparable to C4.5, and using MinCov as a mining algorithm the average hit rate of predicting the sign of stock return is 23.92% higher than that on the original data. This means that the predicting accuracy has been remarkably improved by means of the proposed data reduction and noise filtering method.
Prospects of microbial cell factories developed through systems metabolic engineering

While academic-level studies on metabolic engineering of microorganisms for production of chemicals and fuels are ever growing, a significantly lower number of such production processes have reached commercial-scale. In this work, we review the challenges associated with moving from laboratory-scale demonstration of microbial chemical or fuel production to actual commercialization, focusing on key requirements on the production organism that need to be considered during the metabolic engineering process. Metabolic engineering strategies should take into account techno-economic factors such as the choice of feedstock, the product yield, productivity and titre, and the cost effectiveness of midstream and downstream processes. Also, it is important to develop an industrial strain through metabolic engineering for pathway construction and flux optimization together with increasing tolerance to products and inhibitors present in the feedstock, and ensuring genetic stability and strain robustness under actual fermentation conditions.
Non-linear Analysis of Scalp EEG by Using Bispectra: The Effect of the Reference Choice

Bispectral analysis is a signal processing technique that makes it possible to capture the non-linear and non-Gaussian properties of the EEG signals. It has found various applications in EEG research and clinical practice, including the assessment of anesthetic depth, the identification of epileptic seizures, and more recently, the evaluation of non-linear cross-frequency brain functional connectivity. However, the validity and reliability of the indices drawn from bispectral analysis of EEG signals are potentially biased by the use of a non-neutral EEG reference. The present study aims at investigating the effects of the reference choice on the analysis of the non-linear features of EEG signals through bicoherence, as well as on the estimation of cross-frequency EEG connectivity through two different non-linear measures, i.e., the cross-bicoherence and the antisymmetric cross-bicoherence. To this end, four commonly used reference schemes were considered: the vertex electrode (Cz), the digitally linked mastoids, the average reference, and the Reference Electrode Standardization Technique (REST). The reference effects were assessed both in simulations and in a real EEG experiment. The simulations allowed to investigated: (i) the effects of the electrode density on the performance of the above references in the estimation of bispectral measures; and (ii) the effects of the head model accuracy in the performance of the REST. For real data, the EEG signals recorded from 10 subjects during eyes open resting state were examined, and the distortions induced by the reference choice in the patterns of alpha-beta bicoherence, cross-bicoherence, and antisymmetric cross-bicoherence were assessed. The results showed significant differences in the findings depending on the chosen reference, with the REST providing superior performance than all the other references in approximating the ideal neutral reference. In conclusion, this study highlights the importance of considering the effects of the reference choice in the interpretation and comparison of the results of bispectral analysis of scalp EEG.
When Female Applicants Meet Sexist Interviewers: The Costs of Being a Target of Benevolent Sexism

American undergraduate participants (N=205) read an interview transcript and then evaluated male interviewers and a female job applicant to investigate perceptions of women who receive benevolent or hostile sexism (relative to non-sexist controls). As predicted, positive evaluations of the male interviewer in the benevolent and hostile sexist conditions negatively predicted participants’ hiring decisions—an effect that was fully mediated by low ratings of applicant competence. In accord with ambivalent sexism theory’s claim that women who challenge male dominance are not eligible for protective paternalism, participants’ hostile sexism scores predicted lower ratings of applicant competence and hireability, but only when the interviewer was a benevolent sexist. Implications for workplace discrimination are discussed.
Features of a fully renewable US electricity system: Optimized mixes of wind and solar PV and transmission grid extensions

Wind and solar PV generation data for the entire contiguous US are calculated, on the basis of 32 years of weather data with temporal resolution of one hour and spatial resolution of 40×40 km, assuming site-suitability-based as well as stochastic wind and solar PV capacity distributions throughout the country. These data are used to investigate a fully renewable electricity system, resting primarily upon wind and solar PV power. We find that the seasonal optimal mix of wind and solar PV comes at around 80% solar PV share, owing to the US summer load peak. By picking this mix, long-term storage requirements can be more than halved compared to a wind only mix. The daily optimal mix lies at about 80% wind share due to the nightly gap in solar PV production. Picking this mix instead of solar only reduces backup energy needs by about 50%. Furthermore, we calculate shifts in FERC (Federal Energy Regulatory Commission)-level LCOE (Levelized Costs Of Electricity) for wind and solar PV due to their differing resource quality and fluctuation patterns. LCOE vary by up to 35% due to regional conditions, and LCOE-optimal mixes turn out to largely follow resource quality. A transmission network enhancement among FERC regions is constructed to transfer high penetrations of solar and wind across FERC boundaries, based on a novel least-cost optimization approach.
A RARE CASE OF EPIDERMOID CYST OF CLITORIS

Epidermoid cysts are slow growing tumours of the epidermal cells, commonly seen in neck, scalp, face or trunk. Generally, epidermoid cysts of the clitoris are seen after genital mutilation and trauma. We hereby report a case of epidermoid cyst of clitoris in a 16 year old girl who presented with complaints of genital swelling without any history of previous mutilation / trauma. Simple resection of the cyst was done with complete cosmetic recovery.
On the security of TLS renegotiation

The Transport Layer Security (TLS) protocol is the most widely used security protocol on the Internet. It supports negotiation of a wide variety of cryptographic primitives through different cipher suites, various modes of client authentication, and additional features such as renegotiation. Despite its widespread use, only recently has the full TLS protocol been proven secure, and only the core cryptographic protocol with no additional features. These additional features have been the cause of several practical attacks on TLS. In 2009, Ray and Dispensa demonstrated how TLS renegotiation allows an attacker to splice together its own session with that of a victim, resulting in a man-in-the-middle attack on TLS-reliant applications such as HTTP. TLS was subsequently patched with two defence mechanisms for protection against this attack.
 We present the first formal treatment of renegotiation in secure channel establishment protocols. We add optional renegotiation to the authenticated and confidential channel establishment model of Jager et al., an adaptation of the Bellare--Rogaway authenticated key exchange model. We describe the attack of Ray and Dispensa on TLS within our model. We show generically that the proposed fixes for TLS offer good protection against renegotiation attacks, and give a simple new countermeasure that provides renegotiation security for TLS even in the face of stronger adversaries.

Hypertension and hearing impairment in workers of iron and steel industry.

The objectives of the present study were to study the (i) prevalence of hypertension and hearing impairment in iron and steel industry workers, (ii) association between hypertension and hearing impairment, (iii) association between hypertension and hearing impairment, with duration of exposure, and (iv) correlation between levels of sound and noise induced health problems viz. hypertension and hearing impairment in a cross sectional study involving Workers working in iron and steel industry at Nagpur. Of a total of 804 workers, 770 workers participated in the study. There were five sections in the factory; Steel melting section (SMS), rolling mill section (RMS), quality control department (QCD), maintenance department (MD) and administration department (AD). Workers working in SMS, RMS, & QCD formed a continuously exposed group (CEG); workers of MD and AD formed intermittently exposed group (IEG). Workers were interviewed, examined and information was collected in a pre-tested pro-forma. Blood pressure was measured, and tuning fork tests were done to assess hearing ability. Prevalence of hypertension among CEG (25.51%) was significantly higher than IEG (14.05%). (X2-14.28, df-1, P<0.001). There was positive association between duration of exposure and prevalence of hypertension. The prevalence of hearing impairment was significantly more in CEG (20.5%) as compared to IEG (8.91%). (X2-11.69, df-1, P<0.001). Occurrence of hearing impairment was also directly proportional to the duration of exposure. The correlation between level of sound exposure and hearing impairment was found to be significant (r=0.98; P<0.05), the correlation between level of sound and hypertension was found to be statistically insignificant (r=0.84; P>0.05). The results of the present study indicate that hypertension and hearing impairment are commoner in workers continuously exposed to high levels of occupational noise.
Recovery in remitted first-episode psychosis at 7 years of follow-up of an early dose reduction/discontinuation or maintenance treatment strategy: long-term follow-up of a 2-year randomized clinical trial.

IMPORTANCE
Short-term outcome studies of antipsychotic dose-reduction/discontinuation strategies in patients with remitted first-episode psychosis (FEP) showed higher relapse rates but no other disadvantages compared with maintenance treatment; however, long-term effects on recovery have not been studied before.


OBJECTIVE
To compare rates of recovery in patients with remitted FEP after 7 years of follow-up of a dose reduction/discontinuation (DR) vs maintenance treatment (MT) trial.


DESIGN
Seven-year follow-up of a 2-year open randomized clinical trial comparing MT and DR.


SETTING
One hundred twenty-eight patients participating in the original trial were recruited from 257 patients with FEP referred from October 2001 to December 2002 to 7 mental health care services in a 3.2 million-population catchment area. Of these, 111 patients refused to participate and 18 patients did not experience remission. PARTICIPANTS After 7 years, 103 patients (80.5%) of 128 patients who were included in the original trial were located and consented to follow-up assessment.


INTERVENTION
After 6 months of remission, patients were randomly assigned to DR strategy or MT for 18 months. After the trial, treatment was at the discretion of the clinician.


MAIN OUTCOMES AND MEASURES
Primary outcome was rate of recovery, defined as meeting the criteria of symptomatic and functional remission. Determinants of recovery were examined using logistic regression analysis; the treatment strategy (MT or DR) was controlled for baseline parameters.


RESULTS
The DR patients experienced twice the recovery rate of the MT patients (40.4% vs 17.6%). Logistic regression showed an odds ratio of 3.49 (P = .01). Better DR recovery rates were related to higher functional remission rates in the DR group but were not related to symptomatic remission rates.


CONCLUSIONS AND RELEVANCE
Dose reduction/discontinuation of antipsychotics during the early stages of remitted FEP shows superior long-term recovery rates compared with the rates achieved with MT. To our knowledge, this is the first study showing long-term gains of an early-course DR strategy in patients with remitted FEP. Additional studies are necessary before these results are incorporated into general practice.

Study and Analysis of Routing and Spectrum Allocation (RSA) and Routing, Modulation and Spectrum Allocation (RMSA) Algorithms in Elastic Optical Networks (EONs)

With the growth of Internet users’ traffic demands, the efficient and cost-effective usage of bandwidth and spectrum in optical networks plays an important role in improving service provisioning. An Elastic Optical Network (EON) is a new generation of optical networking that can provide high flexibility and scalability in spectrum allocation and data rate accommodation to support different traffic types. In fact, EON can allocate the available resources in a network according to users’ demands. Besides, EON generates elastic optical paths (the paths with variable bit rates) and divides available spectrum flexibly according to the traffic demands of users. This study reviews and analyzes one of the most important topics in EON namely Routing and Spectrum Allocation (RSA). In fact, RSA selects the most appropriate resources according to the conditions of the resources and flexibility assigns them to the connection demands. RSA can be divided into two categories: without adjusting modulation format (simply referred to as RSA) and with adjusting modulation format (called Routing, Modulation and Spectrum Allocation (RMSA)). In this article, we review all available RSA and RMSA algorithms proposed for EON, analyze and compare them through both quality of performance and computational complexity aspects for the first time.
Process simulation using finite element method — prediction of cutting forces, tool stresses and temperatures in high-speed flat end milling

End milling of die/mold steels is a highly demanding operation because of the temperatures and stresses generated on the cutting tool due to high workpiece hardness. Modeling and simulation of cutting processes have the potential for improving cutting tool designs and selecting optimum conditions, especially in advanced applications such as high-speed milling. The main objective of this study was to develop a methodology for simulating the cutting process in flat end milling operation and predicting chip flow, cutting forces, tool stresses and temperatures using finite element analysis (FEA). As an application, machining of P-20 mold steel at 30 HRC hardness using uncoated carbide tooling was investigated. Using the commercially available software DEFORM-2D , previously developed flow stress data of the workpiece material and friction at the chip–tool contact at high deformation rates and temperatures were used. A modular representation of undeformed chip geometry was used by utilizing plane strain and axisymmetric workpiece deformation models in order to predict chip formation at the primary and secondary cutting edges of the flat end milling insert. Dry machining experiments for slot milling were conducted using single insert flat end mills with a straight cutting edge (i.e. null helix angle). Comparisons of predicted cutting forces with the measured forces showed reasonable agreement and indicate that the tool stresses and temperatures are also predicted with acceptable accuracy. The highest tool temperatures were predicted at the primary cutting edge of the flat end mill insert regardless of cutting conditions. These temperatures increase wear development at the primary cutting edge. However, the highest tool stresses were predicted at the secondary (around corner radius) cutting edge.  2000 Elsevier Science Ltd. All rights reserved.
Diagnosis of cystic fibrosis by sweat testing: age-specific reference intervals.

OBJECTIVE
To develop reference intervals (RIs) for sweat chloride and sodium in healthy children, adolescents, and adults.


STUDY DESIGN
Healthy, unrelated subjects aged from 5 to >50 years and subjects who were pancreatic insufficient with cystic fibrosis (CF) were recruited. Sweat collection was performed on all subjects with the Wescor Macroduct system. Sweat electrolytes were analyzed with direct ion selective electrodes. DeltaF508 mutation analysis was performed on the healthy subjects >/=15 years old.


RESULTS
A total of 282 healthy and 40 subjects with CF were included for analysis. There was no overlap of sweat chloride between the group with CF and the group without CF, but there was some overlap of sweat sodium. Sweat chloride increased with age, with the rate of increase slowing progressively to zero after the age of 19 years. The estimated median (95% RI) for sweat chloride were: 5 to 9 years, 13 mmol/L (1-39 mmol/L); 10 to 14 years, 18mmol/L (3-47 mmol/L); 15 to 19 years, 20 mmol/L (3-51mmol/L); and 20+ years 23 mmol/L (5-56mmol/L).


CONCLUSIONS
We have successfully developed the age-related RI for sweat electrolytes, which will be useful for clinicians interpreting sweat test results from children, adolescents, and adults.
