Design for the Future Design Education: Student works of Politecnico di Milano
No full textToday's design education is facing new challenges!
“Critical, Sustainable, Collaborative" are our keywords to respond to the challenges.
The exhibition works come from more than 100 works with 7 degrees from the Politecnico di Milano and are divided into three exhibition areas of "large, medium, and small" on the scale of the design.
We believe that students have always been an important criterion for measuring design education quality. The curators, designers, and builders of this exhibition are all students of the PoliMi

Review: YANG JIECHANG, ART OF THE REAL
Get PDFThis is an abstract from an exhibition catalogue. The author, Hou Hanru, a celebrated Chinese critic and curator who lives and works in Europe and the US, discusses how Jie-Chang Yang used his calligraphy and ink paintings to deconstruct the exoticized image of Chinese art. Some manufacturing details of Yang\u27s work are introduced later in the essay. Jie-Chang Yang\u27s idea of the relationship between man and nature as well as man and culture is embodied via these arts, according to the author.

PT Hou-Tech Indonesia memiliki 3 orang ekspatriat yang menduduki jabatan top management, yaitu satu orang sebagai Presiden Direktur dan dua orang sebagai Wakil Presiden Direktur.
Metode penelitian yang digunakan dalam penelitian ini adalah penelitian deskriptif dengan pendekatan kualitatif. Metode pengumpulan data yang digunakan adalah wawancara, observasi dan dokumentasi. Metode analisis data yang digunakan dalam penelitian ini adalah triangulasi (yang digunakan untuk mengecek keabsahan data), reduksi data, penyajian data serta penarikan kesimpulan.
Hasil penelitian menunjukkan bahwa terdapat 2 budaya kerja Jepang yang diterapkan oleh ekspatriat pada PT Hou-Tech Indonesia, yaitu Kaizen dan 5S (Seiri, Seiton, Seiso, Seiketsu dan Shitsuke). Dua budaya kerja Jepang tersebut biasa digunakan oleh ekspatriat pada saat masih bekerja di Jepang. Selain itu, ternyata budaya kerja Jepang Kaizen dan 5S juga sudah diterapkan di perusahaan induk, yaitu Hou-Tech Co., Ltd. Baik ekspatriat, manajer Sumber Daya Manusia maupun karyawan lokal menilai bahwa penerapan budaya kerja Jepang sudah cukup berhasil dan sangat berperan penting dalam menigkatkan kinerja karyawan lokal. Bentuk peningkatan kinerja karyawan lokal dapat dilihat secara kuantitas maupun kualitas
Regularity and well-posedness of a dual program for convex best C1-spline interpolation
No full textAn efficient approach to computing the convex best C1-spline interpolant
to a given set of data is to solve an associated dual program by standard numerical
methods (e.g., Newton’s method). We study regularity and well-posedness of the
dual program: two important issues that have been not yet well-addressed in the literature.
Our regularity results characterize the case when the generalized Hessian of the
objective function is positive definite. We also give sufficient conditions for the coerciveness
of the objective function. These results together specify conditions when
the dual program is well-posed and hence justify why Newton’s method is likely to
be successful in practice. Examples are given to illustrate the obtained results
Armijo Newton method for convex best interpolation
No full textNewton's method with Armijo line search (Armijo Newton method) has been practically known extremely efficient for the problem of convex best interpolation and numerical experiment strongly indicates its global convergence. However, similar to the classical Newton method, the Newton matrix far from the solution may be singular or near singular, posing a great deal of difficulties in proving the global convergence of Armijo Newton method. By employing the objective function of Lagrange dual problem, it is observed that whenever the Newton matrix is near singular at some point, one can easily [at cost of O(N), N is the dimension of the problem] find a nearby point which has a well-conditioned Newton matrix and lower function value. In this case, Armijo Newton method starts from this nearby point. We prove that this slightly modified Armijo Newton method is globally as well as locally quadratically convergent, and in an important case, it also has finite termination property. Numerical results demonstrate the efficiency of the proposed method
Boundary conditions with adjustable slip length for the lattice Boltzmann simulation of liquid flow
No full textThe phenomenon of liquid slip has been studied by many researchers using the lattice Boltzmann method. However, boundary conditions for the lattice Boltzmann simulation of liquid flow are far from perfect and how to specify the boundary conditions for liquid flow with slip accurately is still a challenge. In this work, we introduce four widely used slip boundary conditions in gaseous flow into the simulation of liquid flow, two half-way schemes and two modified schemes. Theoretical analysis shows that all half-way schemes are equivalent in principle, so are the modified schemes. According to the equivalence of these schemes, these slip boundary conditions are improved by expanding the range of the combination parameters from [0,1] to [0,2] to surmount the barrier of limited simulated slip length. And the relations between the combination parameters and the slip length are deduced strictly in theory. The specified combination parameter is decided by the given slip length and the relaxation time. The discrete effects of these slip boundary conditions are analysed. If the grid is fine enough, the discrete effects can be ignorable and the local flow at the wall can be approximated as flow with linear velocity gradient. The accuracy and reliability of our method have been verified by the simulations of the Couette flow, the Poiseuille flow and the unsteady Womersley flow. The cylindrical Couette flow is also implemented to explore the possibility of simulating liquid flows with curved boundary
