Leadership capability of team leaders in construction industry
This research was conducted to identify the important leadership capabilities for
Malaysia construction industry team leaders. This research used exploratory sequential
mix-method research design which is qualitative followed by quantitative research
method. In the qualitative phase, semi-structured in-depth interview was selected
and purposive sampling was employed in selecting 15 research participants involving
team leaders and Human Resource Managers. Qualitative data was analysed using
content and thematic analyses. Quantitative data was collected using survey
questionnaire involving 171 randomly selected team leaders as respondents. The data
was analyzed using descriptive and inferential statistics consisting of t-test, One-way
Analysis of Variance (ANOVA), Pearson Correlation, Multiple Regression and
Structured Equation Modeling (SEM). This study found that personal integrity, working
within industry, customer focus and quality, communication and interpersonal skill,
developing and empowering people and working as a team were needed leadership
capabilities among construction industry team leaders. The research was also able to
prove that leadership skill is a key element to develop leadership capability. A
framework was developed based on the results of this study, which can be used as a
guide by employers and relevant agencies in enhancing leadership capability of
Malaysia construction industry team leade
Sec24p and Sec16p cooperate to regulate the GTP cycle of the COPII coat
Vesicle budding from the endoplasmic reticulum (ER) employs a cycle of GTP binding and hydrolysis to regulate assembly of the COPII coat. We have identified a novel mutation (sec24-m11) in the cargo-binding subunit, Sec24p, that specifically impacts the GTP-dependent generation of vesicles in vitro. Using a high-throughput approach, we defined genetic interactions between sec24-m11 and a variety of trafficking components of the early secretory pathway, including the candidate COPII regulators, Sed4p and Sec16p. We defined a fragment of Sec16p that markedly inhibits the Sec23p-and Sec31p-stimulated GTPase activity of Sar1p, and demonstrated that the Sec24p-m11 mutation diminished this inhibitory activity, likely by perturbing the interaction of Sec24p with Sec16p. The consequence of the heightened GTPase activity when Sec24p-m11 is present is the generation of smaller vesicles, leading to accumulation of ER membranes and more stable ER exit sites. We propose that association of Sec24p with Sec16p creates a novel regulatory complex that retards the GTPase activity of the COPII coat to prevent premature vesicle scission, pointing to a fundamental role for GTP hydrolysis in vesicle release rather than in coat assembly/ disassembly
Upper extremity assessment and rehabilitation system for stroke patients
Stroke is the leading cause of disabilities worldwide. Upper extremity impairments are very common after stroke. To support the recovery process, conventional assessment methods such as Fugl-Meyer Assessment (FMA) and Motor Assessment Scale (MAS) are widely used to assess motor performance of stroke patients. However, the assessments face some limitations such as being subjective and time-consuming. Many research have been done to solve the limitations of conventional assessments by using motion capture sensor or robotics for objective assessment. The main objective of this research is to design and develop a vision-based automated rehabilitation and assessment system to assess upper extremity of stroke patients. A Kinect-based system was used as an upper extremity stroke rehabilitation assessment system with isolated training movement namely Shoulder Abduction-Adduction (SAA). Three experiments were conducted involving a total of eight healthy subjects and three stroke patients. A total of six out of nine collected features have been proved being significantly different using t-test method. The suitable features were selected using three different features selection methods, namely Relief-F, Principal Analysis Component, and Correlation-based Feature Selection. These three feature sets were then trained with four different classifiers: Artificial Neural Network (ANN), Support Vector Machine (SVM), Random Tree and Random Forests in order to achieve the best predictive model. With a total of three feature sets and four classifiers, a total of 12 predictive models were constructed in this thesis. The 12 models were evaluated based on correlation-analysis. The result shows that the combination of ReliefF and SVM achieved accuracy of 91.04%, highest correlation coefficient of 0.9929 and lowest root mean square error of 0.1183 among all the constructed models

Simulation 3D des ondes de batillage générées par le passage des bateaux et des processus associée de transport de sédiments
Les ondes de batillage générées par l avancement des bateaux détruisent les rives des voies navigables et accélèrent les phénomènes d érosion aussi bien au niveau des berges qu au niveau du fond du canal. Leurs caractéristiques cinématiques dépendent de la vitesse, de l enfoncement, du chargement du bateau et également de la profondeur de la voie navigable. En outre, les masses d eau accélérées par l immersion des bateaux et par leur système propulsif, induisent la remise en suspension d une grande quantité de sédiments et provoquent l érosion du fond de la voie navigable.Dans cette thèse, un modèle numérique 3D est présenté pour simuler la génération de ces ondes de batillage. Ce modèle, basé sur les équations de Navier-Stokes (RANS), a été couplé à un modèle d advection-diffusion 3D pour caractériser la répartition et le mode de transport sédimentaire au passage du bateau. Ce couplage est mis en oeuvre avec prise en compte des effets des hélices du système propulsif du bateau.Ship-generated waves in restricted waterways lead to the stream banks erosion and cause environmental damage which harms fish, plants, benthos, plankton, etc. They also alter the channel morphology because of the resuspension and transport of bed material by accelerated flows caused by moving-ships. The magnitude of these waves depends mainly on the geometrical and kinematical parameters of the convoy.The objective of this study is to predict the relationship between these geometrical and kinematical parameters and the amplitude of ship-generated waves as well as the water plane drawdown. Numerical simulations are conducted by solving the 3-dimensional Navier-Stokes equations along with the k- model for turbulent processes. The results are compared firstly with the empirical models and secondly with experimental measurements performed by the French Compagnie Nationale of Rhône (CNR). The exitance of the propeller increases the sediment in suspension. Therefore, the relationships between the re-suspended sediments and the advancing speeds of the convoy, the wakes generated by the moving convoy, as well as the number of barges are studied by adding 3D advection-diffusion equation and a propeller model.COMPIEGNE-BU (601592101) / SudocSudocFranceF
