Sekolah Bisa Jadi Sumber Stres Anak

KOMPAS.com – Di sekolah, guru adalah pengganti orangtua bagi anak. Selain itu, tujuan pendidikan sesungguhnya adalah membentuk anak menjadi pribadi yang antara lain cerdas secara intelektual dan emosional. Kenyataannya, guru dan aturan sekolah seringkali menjadi sumber stres anak. Inilah contoh dan solusinya:

Terlalu banyak PR
Solusi: PR banyak tidak akan menimbulkan stres jika ada jadwal rutin untuk mengerjakannya. Orangtua harus membantu anak mengatur prioritas jadwal rutinnya di rumah. Lakukan kerjasama dengan pihak sekolah, diskusikan dengan guru bagaimana menciptakan PR dalam bentuk lain yang dapat dilakukan sambil bermain.

 

On local gouging in five-axis sculptured surface machining using flat-end tools

Abstract
This paper proposes an exact method for the detection and elimination of local gouging, at a cutter contact point, in five-axis machining of sculptured surfaces using flat-end tools. The designed surface is assumed to be at least C2 and could have C1 and/or C0 seams. q2000 Elsevier Science Ltd. All rights reserved.

A novel haptics-based interface and sculpting system for physics-based geometric design

Abstract
Conventional geometric design techniques based on B-splines and NURBS often require tedious control-point manipulation and/or painstaking constraint speci®cation via unnatural mouse-based computer interfaces. In this paper, we propose a novel and natural haptic interface and present a physics-based geometric modeling approach that facilitates interactive sculpting of spline-based virtual material. Using the PHANToM haptic device, modelers can feel the physically realistic presence of virtual spline objects and interactively deform virtual materials with force feedback throughout the design process. We develop various haptic sculpting tools to expedite the deformation of B-spline surfaces with haptic feedback and constraints. The most signi®cant contribution of this paper is that point, normal, and curvature constraints can be speci®ed interactively and modi®ed naturally using forces. To achieve the real-time sculpting performance, we devise a novel dual representation for B-spline surfaces in both physical and mathematical space: the physics-based mass-spring model is mathematically constrained by the B-spline surface throughout the sculpting session. We envision that the integration of haptics with traditional computer-aided design makes it possible to realize all the potential offered by both haptic sculpting and physics-based modeling in CAD/CAM, virtual prototyping, human±computer interface, and medical training and simulation. q 2001 Elsevier Science Ltd.

Membongkar Gurita Cikeas – FULL

Pengarang: George Junus Aditjondro

Penerbit: Galang Press

Ukuran: 6.7 MB

Format: Pdf

Buku Membongkar Gurita Cikeas yang ditulis oleh George Junus Adijtondro telah menjadi perbincangan super hangat di masyarakat. Menurut beberapa sumber, Buku setebal 183 halaman ini salah satunya berisi pembahasan mengenai oligarki kekuasaan yang terbangun di seputar lingkaran kekuasaan SBY.

Kini buku tersebut menjadi incaran banyak orang yang ingin tahu seperti apa isinya, maklum buku Gurita Cikeas saat  ini telah menghilang dari peredaran, hmm.. entah siapa yang menyuruh ditariknya kembali buku itu dari pasaran.

Dalam buku Membongkar Gurita Cikeas George menjelaskan, lingkaran kekuasaan yang dimaksud adalah tiga komponen penyokong kekuasaan SBY. Yakni para menteri atau pejabat, pengusaha, dan keluarga.

Tiga komponen ini, lanjut George, memiliki kontribusi besar dalam kemenangan SBY pada Pemilu 2009. Sedangkan skandal kasus Bank Century yang dipakai sebagai sub judul, hanya sebagai salah satu contoh kasus kecil pengguliran dana kampanye untuk SBY.

Kira-kira seperti itulah isi buku Gurita Cikeas yang menggemparkan tersebut. Admin sendiri sedang mencari link download e-book ini barangkali ada yg sudah simpan di internet . Bagi yang penasaran seperti apa isi buku membongkar Gurita Cikeas anda bisa melihat resensinya berikut saya petik dari inilah.com

CFACA: component framework for feature-based design and process planning

Abstract
Automatic generation of manufacturing information from design has been the research focus in advanced CAD/CAM applications, i.e. feature-based applications for design, process planning and other automated manufacturing applications. However, our current development mode has seriously troubled research in these application fields. For example, with our current development mode, the functionality and data of one application cannot be accessed by other applications; applications are monolithic, they are time-consuming to develop and hard to customize and update for meeting the user’s requirements. Typically, each researcher has to develop independently a complete set of new monolithic application almost built from scratch to create features and then perform various process-planning functionalities. This development mode leads to such a tremendous and tough work in advanced CAD/CAM applications that, though researchers in these fields have developed countless feature-based application programs, the problem of integrating CAD and CAM applications is still largely unsolved. From the viewpoint of component technology, we seem to be wasting more time than we should be, doing ineffective work that is orders of magnitude greater and harder. The component technology, which emerged in the 1990s, has been widely regarded as the software development technology of tomorrow, and is changing the development mode of the software industry now, but has never been explored in advanced CAD/CAM application fields. The paper introduces a method of achieving the new technology in advanced CAD/CAM application fields. As an example, the paper discusses in detail the interface components in feature-based machining application domain to explain how the component technology is used in a specific advanced CAD/CAM field and how powerful the technology is. The framework in the paper is the first component framework for advanced CAD/CAM applications. Because the component technology provides developers with much more productive and powerful development mode, it is believed that this development technology is the technology of tomorrow in advanced CAD/CAM fields, and that it will change the development mode of advanced CAD/CAM applications. q2000 Elsevier Science Ltd.
