In terms of such implementation, this paper shows that the previously discussed S-L projection learning is inappropriate to constructing a family of projection learning, and proposes a new version called partial oblique projection (POP) learning. In POP learning, a function space is decomposed into two complementary subspaces, so that functions belonging to one of the subspaces can be completely estimated in noiseless case; while in noisy case, the dispersions are set to be the smallest. In addition, a general form of POP learning is presented and the results of a simulation are given.展开更多

The new network combines the advantages of both projectionpursuit and wavelet shrinkage. Restoring image is very difficult when little is known about apriori knowledge for multisource degraded factors. WDPPLN successfully resolves this problemby separately processing wavelet coefficients and scale coefficients. Parameters in WDPPLN,which are used to simulate degraded factors, are estimated via WDPPLN training, using scalecoefficients. Also, WDPPLN uses soft-threshold of wavelet shrinkage technique to suppress noisein three high frequency subbands. The new method is compared with the traditional methodsand the Projection Pursuit Learning Network (PPLN) method. Experimental results demonstratethat it is an effective method for unsupervised restoring degraded image.展开更多

Using the Lyapunov--Krasovskii functional stability theory, a differential-difference mixed parametric learning law and an adaptive learning control law are constructed to make the states of two different chaotic systems asymptotically synchronised. The scheme is successfully applied to the generalized projective synchronisation between the Lorenz system and Chen system. Moreover, numerical simulations results are used to verify the effectiveness of the proposed scheme.展开更多

Society expects university students to gain certain basic skills important when working for a company. These skills can be divided broadly into action, thinking, and teamwork. The purpose of this paper is to propose a method of project-based education for developing fundamental competencies for working persons. Many studies have been reported on educational methods with project management techniques, but few have considered project-based education aiming at improving fundamental competencies for working persons. If these competencies can be developed through project-based education, it will be possible to develop not only teamwork skills, but also a wide range of skills involving action as well as thinking. The traditional Japanese university curriculum comprises specialized subjects and the liberal arts. The author proposes the addition of project-based education to develop basic skills needed in the workforce. This research proposes an education model for basic competency training and examines the educational outcomes by studying results of a cooking tool project assigned to university students. The model includes Teoriya Resheniya Izobretatelskikh Zadatch (TRIZ, a Russian acronym for the theory of inventive problem solving), a World Cafe, and the SECI process (a process of knowledge creation comprised of socialization, externalization, combination, and internalization in knowledge management) in the hope that this model will be conducive to implementing effective project-based learning. This research concludes that it is possible to develop the basic skills needed by university students in society through project-based learning under a basic skills education model.展开更多

Despite the growing awareness, relatively fewer project-based firms have institutionalized mechanisms to systematically capture new project knowledge and re-use it to improve the execution of subsequent projects. The peculiarity of projects presents unique challenges that make the cognitive approach to learning difficult to implement. As such, researchers are recommending the social constructivist perspective of learning as the most viable strategy for cultivating learning within and across projects. However, scant work has been undertaken from this sociological perspective to analyze how temporary organizations manage knowledge arising from and relating to projects. From this standpoint, the aim of this paper is to discuss the learning mechanisms of construction firms. The study adopted a quantitative strategy by employing a questionnaire survey into the learning practices of construction projects in Ghana. Drawing on preliminary findings from the literature, the study proposes a model for cultivating learning within projects from the social constructivist viewpoint. In the model, project management practitioners can purposefully nurture or structure a project learning activity through four mechanisms <em>viz</em>.: <em>institutionalization, externalization, socialization and internalization</em>. The proposed model is subsequently validated in an empirical study into the learning practices during the implementation of construction projects in Ghana. Based on the empirical results, it seems that knowledge sharing and transfers through the four aforementioned learning mechanisms proposed by the model are highly regarded within project management practice in Ghana.展开更多

To reflect some real situations, the learning effect is considered in the project portfolio selection problem for the first time.

One numerical example under different scenarios is demonstrated and the impact of considering learning effect is then discussed.展开更多
