Abstract:
Background: Smart phones have become an integral part of youth. But at the same time addiction towards its use have become a serious concern among them. The objective of this study was to evaluate the level of smart phone usage among medical college students and their demographic characteristics.Methods: A cross sectional study was conducted on 192 medical students. A self administered SAS scale has been used to assess the level of smart phone addiction. Subjects were classified into smart phone non-user group, a low smart phone user group and a high smart phone user group.Results: Out of 192 subjects who completed the questionnaires 85.40% (n=164) had smart phone addiction. Out of the total 192 students 28 students (14.60%) were low smart phone users, of which 9 were boys (14.30%) and 19 were girls (14.70%). Among 164 (85.40%) high smart phone users 54 students were boys (85.70%) and 110 were girls (85.30%) which was not statistically significant at 5% level (chi square=0.007, p=0.935).Conclusions: Medical college students in Andaman and Nicobar Islands are more vulnerable for smart phone addiction.

Abstract:
A fresh split gill mushroom or locally known as cendawan kukur (Schizophyllum commune Fr.) (SC) was obtained from Terengganu, Malaysia. The SC samples were dried in an oven and extracted with several polarities of solvent such as water, ethanol, dichloromethane and hexane. Then the SC extracts were tested for their scavenging activity against the DDPH radical models. The scavenging activities were calculated as a percentage of DDPH radicals discolouration and measured as scavenging activities of the S. commune extracts. The finding observed the highest scavenging activities resulted from SC-H2O (85.40%), followed by SC-ethanol (54.91%), SC-dichloromethane (0.46%) extracts and no observation of scavenging activities showed by a non-polar extract (SCHexane). In this finding, the scavenging activity of SC-H2O extract against DDPH radicals was found more potent at 85.40% and it showed the highest activities as compared to the other SC-DCM and SC-EtOH extracts. In the next observation, the scavenging activities of the single SC-water extract against free radical DDPH were observed for another 30 mins by an interval of 5 mins increment after the incubation time. As a result, the scavenging activities of SC-H2O extract against DDPH free radicals maintained its activities between 85.40-85.76% within 30 mins. These observed that the SC-H2O extracts presented a highly potent antioxidant as compared to other SC extracts in this model. Finally, an additional HPTLC method was used as a preliminary observation of the SC extract separation profiles. The result of SC water extracts (polar extract) observed the same Rf value (0.25) of the unknown compound as compared to the SC-EtOH and SCDCM extracts, and this spot compound was not observed in the non-polar extract of SCHexane. The polar and mid-polar extractable materials were more abundant in TLC separations and are related to the % TSS and strength of the mushroom aroma in the extracts. These preliminary studies will be continued for the S. commune phytochemicals discovery and the development of a new product of S. commune flavour extracts.

Abstract:
A Re-rich phase (up to 85.40% wt.Re) was occasionally found in a single crystal superalloy during thermal exposure. Interestingly, this phase is located in front of the dendrite periphery in the interdendritic region, while the Re is segregated in the dendrite core. Formation of this phase was suggested to relate to the unusual accumulation of the Re resulting from the uneven diffusion process of Re. Appearance of this phase may imply the preference of forming Re-Re atomic bond in the superalloys.

Abstract:
Une très faible lumière nous parvient depuis le ciel. Celle-ci n'est pas uniformément répartie sur la carte du ciel mais présente des anistropies. En analysant ces anistropies, nous pouvons déduire son spectre de puissance, ce qui nous permet de déduire les paramètres de l'univers. En supposant que le modèle statistique de génération de ces anistropies soit un modèle hiéarchique linéaire Gaussien et en ajoutant une distribution a priori sur les paramètres, nous pouvons faire de l'inférence Bayésienne sur ces paramètres. Ceci nous permet d'avoir non pas seulement un estimateur ponctuel des paramètres mais aussi des barres d'erreur sur ces quantités. Afin de mener à bien cette inférence, nous reprenons et développons l'échantillonneur de Gibbs utilisé jusque là dans la littérature sur l'analyse du fond diffus cosmologique. Nous proposons un moyen de raccourcir le temps de résolution d'un système en très grande dimension tout en gardant la distribution cible invariante. Nous proposons également un algorithme basé sur une variable auxiliaire pour contourner cette résolution. Finalement, en présentant les paramétrisations centrée et non centrée, nous utilisons une stratégie d'interweaving afin d'avoir un algorithme mélangeant bien sur l'ensemble du ratio signal sur bruit.Le second projet concerne la compression des chaînes de MCMC. Sous-échantillonner une chaîne de Markov augmente toujours la variance asymptotique de l'estimateur obtenu. Nous voulons donc garder les points les plus représentatifs afin que cette variance asymptotique n'augmente pas trop. En utilisant une méthode d'échantillonnage pour des sondages et des "control variates", nous proposons une méthode en deux étapes afin de ne garder les points les plus représentatifs de la loi cible parmi une chaîne de MCMC: d'abord, nous utilisons des control-variates afin d'obtenir un estimateur s'écrivant comme une somme pondérée de la chaîne initiale. Ensuite, nous utilisons la méthode du cube afin de sous-échantillonner la chaîne pondérée obtenue à l'étape précédente. Nous proposons une façon de gérer les poids négatifs que la première étape peut donner. Nous proposons également deux façons d'avoir des control-variates: l'une, basée sur le "Stein trick" et la seconde, basée sur les control-variates de Gibbs. Ainsi, notre méthode ne nécessite pas la fonction de score
We receive a faint light from the sky. This light is not uniform on the map of the sky but presents anisotropies. From these anisotropies, we can deduce its power spectrum, which in turn allows us to determine the cosmological parameters of the universe. Assuming the statistical model generating the sky map is a hierarchical linear Gaussian model and adding a prior distribution on the parameters, we can make Bayesian inference on these parameters. This allows us not only to have point estimates of the parameters, but also error bars on these quantities. In order to make this inference, we further develop the usual Gibbs sampler used in the CMB data analysis literature. We propose a way to shorten the resolution of a very high dimensional system while keeping the target distribution invariant. We also offer an algorithm based on an auxiliary variable to get around this resolution. Finally, using the concepts of centered and non centered parametrization, we use an interweaving strategy to have good mixing properties on the entire signal-to-noise ratio range.The second project regards the compression of MCMC chains. Subsampling a Markov chain always increases the asymptotic variance of the resulting estimator. Hence we want to keep the points that are the most representative so that this variance does not increase too much. Using a survey sampling method and control variates, we propose a two steps procedure to keep the points that are the most representative of the target distribution out of a MCMC chain: first, we use control-variates in order to get an estimator which writes as a weighted sum of the chain. Then, we use the cube method to subsample the weighted chain we got at the end of the first step. We propose a way to deal with negative weights arising at the first step, which are incompatible with the cube method. We also provide two ways to build control-variates: one based on the Stein trick and the other one based on the Gibbs control variates. Hence, our method does not necessitate the availability of the score function

Abstract:
While studies indicate there is a strong link between pro-environmental values and behaviour, they also show that such values are not necessarily enacted consistently across all areas of our lives. There are many psychosocial factors that can affect congruent enactment. Improving our understanding of what these factors are and how they influence cognition and behaviour is critical for subverting our inadequate response to ecological crisis, yet it is an area that remains under explored. In this thesis I investigate factors affecting enactment of pro-environmental values by individuals in organisational contexts. Integrating Interpretative Phenomenological Analysis with frame and metaphor analysis in an innovative transdisciplinary and cross-level methodology, my study enquires into the lived, embodied and situated experience of six sustainability managers and leaders in the UK and Canada in their work to influence pro-environmental practices in their organisations. Using semi- structured interviews as the primary data source, over 70 highly nuanced and in-depth findings are generated, enriching our understanding of psychological threat coping strategies from a systemic perspective: • Sources of threats and tensions that arise for sustainability managers in their work to influence organisational practices (e.g. thwarted autonomy, competency or relatedness needs, incongruence in values) • Types of coping strategies used to negotiate these tensions (including identity work, emotion regulation, seeking support from external partners, constructing a motivational story, nature connection) • Ecologically adaptive and maladaptive outcomes of these responses for the individual and the organisation (including indirect impacts on vitality and effectiveness) • Factors affecting the efficacy of adaptive coping strategies (e.g. type of motivation, type of self-awareness, cognitive frames about nature) • Contextual factors (organisational, cultural worldview) • How these factors interact with each other, creating feedback loops The conceptual models I have constructed make these largely unconscious psychosocial processes visible; and may be of practical use to individuals in facilitating deeper awareness of the dynamics in their situation and helping to identify where interventions can be made to improve their efficacy and resilience in influencing pro-environmental change in their organisations.

Abstract:
In a context of compelling evidence from both the US and UK suggesting that R&D investment is positively related to operating and/or market performance, at a first stance this PhD Thesis examines the relation between R&D investment and persistence in operating and market performance using a large dataset of UK companies during the period 1990-2003. The findings confirm the relation between R&D intensity and consistent growth in sales and gross income but only when taking the industry sector in which a firm operates into account. Moreover, the evidence found indicates a positive relation between R&D intensity and subsequent risk-adjusted excess stock returns among firms that engage in R&D. There is also shown that R&D intensity improves persistence in excess stock returns: the highest R&D intensity firms are found to earn higher risk-adjusted excess returns than the sample median return more consistently, compared to lower R&D intensity firms, as well as firms with no R&D. The weight of the evidence is consistent with some form of mispricing related to the market's slow adjustment to the emerging evidence of significant enhancement in operating performance following recent R&D investment. The Thesis also examines whether R&D plays a role in the relationship between dispersion in analysts' earnings forecasts and returns, given that R&D has been testified empirically in prior literature as an influencing factor for both forecast dispersion and stock returns separately, and forecast dispersion on its own has been identified as a factor with an impact on returns. In addition, in the context of existing evidence on R&D being positively related with greater analyst forecast errors, the Thesis goes one step further and examines the impact of R&D, intensity on forecast revisions. The hypothesis is in favour of a positive association between R&D and the magnitude of revisions, due to the inherent uncertainty of the R&D investment. These topics are examined again for UK listed firms in the period 1990-2003 and there is testified that R&D intensity is a contributing factor for analyst forecast dispersion for the UK, confirming prior findings for the US. There is confirmed a negative relationship between forecast dispersion and returns, which is found to hold even after controlling for the impact of R&D on returns. After decomposing dispersion in analysts' forecasts into analyst forecast uncertainty and a pure differences in opinion part, there is also found that as R&D intensity increases, the ability of R&D to influence returns also increases for high dispersion and high forecast uncertainty firms, but the ability of R&D to influence returns is getting very week for high divergence of opinion firms. This finding implies that in the presence of high R&D intensity, dispersion has an impact on returns mainly through the forecast uncertainty component of forecast dispersion, and not through the divergence of opinion component. Finally, there is generally found a positive relationship between R&D intensity and forecast errors and revisions, which is most times statistically significant though only in the case of revisions, when there exists a reasonable amount of time between the initial and the revised analyst forecast, after controlling for other factors.

Abstract:
The effects of androgens reach far and wide and can be physiological as well as pathological. They are not limited to males and involve almost every system in the human body. Their influence on reproductive development and behaviours is well studied, but more recently, attention has turned to the wider reaching consequences of androgen exposure. Disorders of sex development (DSD) are rare conditions in which individuals may be deficient in, or resistant to, the effects of androgens. The long-term health and quality of life for these individuals is not well reported, but where there are reports, there are descriptions of increased depressive like behaviours, anxiety and poor social functioning. Lack of androgens has been linked to poorer neurocognitive outcomes in some studies and there is a concern that more aggressive hormone replacement should be considered in early life for those individuals lacking in androgens. These disorders can be difficult to study for many reasons. Firstly, they are rare conditions. Secondly, adults with DSD do not tend to visit hospital regularly and can therefore be challenging to engage in research. Thirdly, studying the effects of early life exposure to steroid hormones and relating these to later life behaviours is incredibly complex. Animal models have been used for many years to study the hormonal environment. For my first study, I used a model of rodent neonatal androgen blockade by treating pups with the anti-androgen flutamide for the first five days of life. The animals were studied again in adolescence (6 weeks of age) and early adulthood (10 weeks of age). There were no significant differences found in testosterone, dihydrotestosterone and androstenedione levels in either age group, demonstrating that the androgen blockade was transient. The anogenital index (AGI) was significantly shorter in the treated animals when compared to controls at 6 weeks of age and 10 weeks of age. Phallus length was significantly shorter in treated males when compared to the healthy males at 6 weeks of age and at 10 weeks of age. Phallus weight was significantly lower in the treated animals at 10 weeks of age when compared to the healthy animals. This work demonstrated that my rodent model of neonatal androgen blockade was an effective one. My next study used the same rodent model and aimed to link the perinatal hormonal environment with in vivo brain chemistry using a painless, non-invasive technique known as Magnetic Resonance Spectroscopy. Using a mixed effects model, I analysed the effects of sex, gender, treatment with flutamide and age on the metabolite pattern of the rodent brain. Ɣ-aminobutyric acid (GABA), glucose, glutamine, glutamate, phosphocholine and myo-inositol all changed over time. The combined peaks of glutamate and glutamine also demonstrated a significant change over time. GABA, glutamate, phosphocholine and myo-inositol showed significant sex differences as did the combined peaks of glycerophosphocholine and phosphocholine, N-acetylaspartate (NAA) and N-acetylaspartylglutamate (NAAG) and glutamate and glutamine. Aspartate, GABA and myo-inositol were all significantly changed by treatment of the animals with flutamide and GABA and myo-inositol levels in treated males were similar to control females at both 6 and 10 weeks. My final study using the rodent model of androgen blockade looked at the histological changes in the brain. Brains were sectioned and stained for neuronal cell counts and microglial cell counts, and PCR for the Androgen Receptor (AR) was performed. I demonstrated significant, sexually dimorphic changes in neuronal cell counts, microglial cell counts and androgen receptor expression in two clearly defined areas in the rodent brain. In summary, my rodent work demonstrated a link between the neonatal hormonal environment and the sexually dimorphic chemistry and histology of the in vivo brain, and supports the hypothesis that the microglial cell plays a critical role in brain masculinisation. To include a translational aspect to this thesis I extended my work to a population of undermasculinised boys, who were attending hospital for an hCG stimulation test as part of their investigations for 46 XY DSD. The hCG stimulation test is a valuable method for assessing androgen production but there is a need to explore its utility in assessing androgen responsiveness and long-term prognosis. I aimed to assess the effects of the hCG test on the in vivo brain chemistry using MRS, and the peripheral transcriptome using microarray. I reliably demonstrated metabolites in the brains of healthy male infants, healthy female infants and affected male infants. Healthy male infants had significantly lower levels of N-acetylaspartate than affected males in the hypothalamus and lower levels of the phosphocholines in the frontal cortex. In my transcriptomic study of DSD patients, I demonstrated the existence of an androgen responsive group of small RNAs that are measurable in peripheral mononuclear blood cells, and that change over the short duration of an hCG stimulation test, raising the prospect of combining the biochemical assessment of testosterone production with an objective molecular assessment of androgen sufficiency. In summary, in this thesis I have successfully linked the early hormonal environment with later life in vivo brain chemistry, confirmed by histological studies. I have also identified a novel marker, which could potentially be used as an assessment of androgen sufficiency in the future.

Abstract:
Se ha observado en los últimos años un incremento del personal de enfermería con formación de grado, lo cual influye en un aumento cuantitativo, pero no denota ni se observa un cambio sustancial en cuanto a la mejora en la atención de pacientes. Es por ello que el presente trabajo de investigación tiene como objetivo fundamental determinar en qué medida la formación de grado de los enfermeros, se refleja en las intervenciones de enfermería al atender a pacientes. Es un estudio de tipo cuantitativo, no experimental de corte transversal y aplicado. La muestra tomada fue no aleatoria e intencional, seleccionando un total de 63 licenciados, que se desempeñan en las áreas de internación, a los que se les realizó una entrevista personal mediante un cuestionario estructurado con preguntas cerradas.

Abstract:
Transition from preschool to first grade primary school has been an important topic for worldwide researchers concerned about the promotion of an effective adaptation process for children entering primary school. Studies have highlighted the importance of this process for children’s academic and personal development. The main aim of this study was to explore the perceptions of transition between preschool and first grade primary school held by teachers, headteachers and parents in the public education system in Mexico City. A questionnaire was developed based on previous transition studies and administered to a sample 15 preschool and 15 primary school teachers. A semi-structured interview was conducted with five parents from preschool and primary school and five headteachers from preschool and primary school in Mexico City. Overall, the results revealed that teachers moderately used some practices (e.g., creating children´s portfolio), whilst some practices were rarely used (e.g., primary school visits). Teachers rarely carry out activities with families and other teachers. Teachers’ reported children´s problems mostly focused on behaviour and following directions. Working in the same school for a number of years, predicted more family involvement in school matters. Preschool teachers who attended more specialised courses reported more children´s problems. Parents and headteachers are aware of this transition and concerned about children’s lack of academic skills; however neither group employs a range of effective transition practices to support children. These findings are in line with the international literature, however, further research is needed to address particularities in Latin American contexts. Findings from this study open a window for further research in Mexican educational settings focused on current educational policy reforms. Implications are discussed for research, policy and practice.

Abstract:
Theoretical and numerical studies of chaotic mixing are performed to circumvent the difficulties of efficient mixing, which come from the lack of turbulence in microfluidic devices. In order to carry out efficient and accurate parametric studies and to identify a fully chaotic state, a spectral element algorithm for solution of the incompressible Navier-Stokes and species transport equations is developed. Using Taylor series expansions in time marching, the new algorithm employs an algebraic factorization scheme on multi-dimensional staggered spectral element grids, and extends classical conforming Galerkin formulations to nonconforming spectral elements. Lagrangian particle tracking methods are utilized to study particle dispersion in the mixing device using spectral element and fourth order Runge-Kutta discretizations in space and time, respectively. Comparative studies of five different techniques commonly employed to identify the chaotic strength and mixing efficiency in microfluidic systems are presented to demonstrate the competitive advantages and shortcomings of each method. These are the stirring index based on the box counting method, Poincare sections, finite time Lyapunov exponents, the probability density function of the stretching field, and mixing index inverse, based on the standard deviation of scalar species distribution. Series of numerical simulations are performed by varying the Peclet number (Pe) at fixed kinematic conditions. The mixing length (lm) is characterized as function of the Pe number, and lm ∝ ln(Pe) scaling is demonstrated for fully chaotic cases. Employing the aforementioned techniques, optimum kinematic conditions and the actuation frequency of the stirrer that result in the highest mixing/stirring efficiency are identified in a zeta potential patterned straight micro channel, where a continuous flow is generated by superposition of a steady pressure driven flow and time periodic electroosmotic flow induced by a stream-wise AC electric field. Finally, it is shown that the invariant manifold of hyperbolic periodic point determines the geometry of fast mixing zones in oscillatory flows in two-dimensional cavity.

Abstract:
In this study, we experimentally studied our newly designed and built 5-cell stack high temperature PEM fuel cell prototype at different operating conditions to investigate the effects of CO poisoning on the cell performance. The effects of temperature variations with different amount of CO poisoning on the current-voltage characteristics of the fuel cell stack are investigated. Experimental data of this type would be very useful to develop design parameters for fuel reformer. The high CO tolerance of high temperature PEM fuel cell stack makes it possible to feed the reformate gas directly from the reformer without further CO removal. Thus, upon considering the fact that a steam reformer is a consumer of heat and water, and the fuel cell stacks are a producer of heat and water, the integration of the fuel cell stack and the reformer is expected to improve the entire system performance. The results obtained from our 5-cell stack test showed variations in current-voltage characteristics at different temperatures with different CO poisoning rates. The results are promising to understand the overall system performance development strategy of high temperature PEM fuel cell in terms of current-voltage characteristics while fed with on-site reformate hydrogen gas with different CO concentrations in the anode feed stream.

Abstract:
Safety related valves in nuclear power plants are required to be qualified in accordance with the ASME QME-1 standard. This standard describes the requirements and the processes for qualifying active mechanical equipment that are used in nuclear power plants. It does not cover the qualification of electrical components that are addressed using IEEE standards; however, QME-1 recognizes that both mechanical and electrical components must be qualified when they are interfaced as an assembly. Qualifying both mechanical and electrical valve assemblies can be challenging. Considerable amount of judgment is used when developing the plan to qualify any valve with an electric motor actuator. If the wrong steps are taken in planning the tests, the results from the tests may not be useful thus triggering the need to perform additional tests to comply with QME-1 requirements. This paper presents lessons learned in the process of qualifying valve assemblies to meet QME-1 requirements. The lessons include the decision processes associated with planning and executing valve testing, analysis of the valve assemblies for natural frequency determination, and missed opportunities to capture relevant test data during the tests. Finally, the paper will discuss challenges associated with justifying the tests and extending the results of the tests to cover untested valve assemblies.

Abstract:
Projectile motion under idealized conditions has been well understood for centuries. However, once aerodynamic forces (drag and lift) are introduced, the motion becomes significantly more difficult to analyze and predict. This paper compares two aerodynamic models on the flight of a baseball — the first by Robert Adair and the second by Greg Sawicki, Mont Hubbards, and William Stronge. Applied to the distance traveled by a baseball, the two models predict substantially different results. The results of the models were further examined through interactive computer simulations using Working Model and Autolev.

Abstract:
Recently, it has been discovered that RF waveguides can be used as onboard wireless sensors for the direct measurements of angular positions of a moving object and that a combination of RF waveguides may be used to measure full spatial angular orientation of the object. This paper deals with the computational issues that arise in resolving the spatial orientation from the measurement data of a set of RF waveguide sensors. The paper presents an algorithm that combines a heuristic search method with the least-squares approach for computing the full orientation of an object. The goal is to develop a general and efficient method for computing spatial orientation from the sensor data of a class of angular position sensors that have smooth sensor profiles.

Abstract:
Designing family of products, instead of single products, using a common platform approach has gained momentum in various industries. One of the main challenges faced by companies includes specifying a product family architecture to support the varieties. Designers need to consider different viewpoints related to product, assembly, manufacturing, etc. during the development of the product family architecture. The purpose of this paper is to present a configuration reasoning method to develop a product family architecture that not only satisfy, but also has improved characteristics for different viewpoints. This paper attempts to accomplish these objectives by developing representations for components, modules, product family architecture, and assembly process. The paper also presents mathematical formulations to generate feasible product family architectures, indices for architecture evaluation, rules to ensure feasibility and improve from multiple viewpoints. The application of this configuration reasoning framework is illustrated using identifying product family architecture for a set of coffeemakers.

Abstract:
The simple beam acts as a constraint element when used in flexure mechanisms. Non-linearities arising from the force equilibrium conditions in a beam significantly affect its properties as a constraint element. Consequently, beam-based flexure mechanisms typically suffer from performance tradeoffs in terms of motion range, accuracy and stiffness. This paper presents simple yet accurate approximations that capture this non-linearity and allow for the closed-form analysis of flexure mechanisms of moderate complexity. These general analytical tools enable a designer to parametrically predict key performance parameters of a conceived mechanism such as mobility, over-constraint, stiffness variation, and error motions, without resorting to tedious numerical or computational methods. To illustrate their effectiveness, these approximations are used in deriving the closed-form force-displacement characteristics of several important beam-based flexure modules, and the results are validated using Finite Element Analysis. Variations in the beam shape and flexure module geometry are also considered analytically.

Abstract:
In this paper, we discuss several applications of automatic differentiation to multibody dynamics. The scope of this paper covers the rigid, flexible, and constrained dynamical systems. Particular emphasis is placed on the development of methods for automating the generation of equations of motion and the simulation of response using automatic differentiation. We also present a new approach for generating exact dynamical representations of flexible multibody systems in a numerical sense using automatic differentiation. Numerical results will be presented to detail the efficiency of the proposed methods.

Abstract:
In this study, an efficient approach for modeling the vibration of multi-stage rotors is proposed in order to allow more realistic predictions of the free and forced response of bladed disks. The reduced-order modeling approach is based on component mode synthesis, with each stage (bladed disk) treated as a separate component. Thus, each component retains cyclic symmetry, and single-sector models may be used for calculating the component modes. Because adjacent stages typically have different numbers of blades, the single-stage models are synthesized by projecting the stage-to-stage interface motion onto a common basis of circumferentially harmonic shapes. In this manner, any mismatch between sector sizes and finite element meshes at the interface can be handled systematically and automatically, without requiring additional multi-point constraints. For further size reduction, secondary modal analysis is performed on the entire synthesized model. Therefore, only a small set of multi-stage modes are retained in the final reduced-order model, yielding an extremely compact model that retains high accuracy relative to the parent finite element model.

Abstract:
This paper proposes to cluster project actors (i.e., members) to form complementary teams based on their interactions and interdependencies with each other. First, the Design Structure Matrix (DSM) is used to model the interactions between project members, which are based on the number of deliverables exchanged between them. Then, an agglomerative clustering technique is proposed to place the project members into groups. The algorithm permits management to impose certain restrictions on team formations, such as the number and maximum size of the teams, which members must be placed together, and which members must be kept apart. Most importantly, the algorithm allows cyclic information exchanges (i.e., loops) to be inserted into team clusters. It produces as output the recommended team formations, as well as the percentage of the total number of interactions that occur within the clustered teams. The proposed clustering method is illustrated using data collected from a vehicle development project at a large European automotive company.
