3B şekil oluşturulma sürecinde herhangi ek donanım gerektirmeyen Odaktan Şekil (Shape From Focus - SFF) en çok tercih edilen stratejilerdendir. SFF stratejisi, oluşturma farklı odaklı 2B görüntü serisi kullanmakta ve üç temel aşamadan oluşmaktadır: (1) Farklı serisinin elde edilmesi, (2) Görüntü piksellerinin odaklama değerlerinin hesaplanması (3) Maksimum pikselin seçilmesi. Yüksek doğruluk da...

This paper investigates an adaptive coordinated control problem of spacecraft formation flying (SFF) system subject to uncertain mass and external perturbations. First, a general unified structure is proposed represent the adjustable performance functions like exponentially appointed-time convergent ones. Then, controller developed based on two-layer envelope characterize transient steady-state...

We present a framework in which the transition between many-body localized (MBL) phase and an ergodic one is symmetry breaking. consider random Floquet spin chains, expressing their averaged spectral form factor (SFF) as function of time terms transfer matrix that acts space direction. The SFF determined by leading eigenvalues this matrix. In MBL phase, eigenvalue unique, symmetry-unbroken whil...

Purpose – To seek to produce low-voltage, soft mechanical actuators entirely via freeform fabrication as part of a larger effort to freeform fabricate complete electromechanical devices with lifelike and/or biocompatible geometry and function. Design/methodology/approach – The authors selected ionomeric polymer-metal composite (IPMC) actuators from the literature and the authors’ own preliminar...

We used estimates of autotrophic respiration (RA), net primary productivity (NPP) and soil CO2 evolution (Sff), to develop component carbon budgets for 12-year-old loblolly pine plantations during the fifth year of a fertilization and irrigation experiment. Annual carbon use in RA was 7.5, 9.0, 15.0, and 15.1MgCha 1 in control (C), irrigated (I), fertilized (F) and irrigated and fertilized (IF)...

A major challenge in tissue engineering is the generation of cell-seeded implants with structures that mimic native tissue, both in anatomic geometries and intratissue cell distributions. By combining the strengths of injection molding tissue engineering with those of solid freeform fabrication (SFF), three-dimensional (3-D) pre-seeded implants were fabricated without custom-tooling, enabling e...

Purpose – The paper’s aim is to show the development of materials and methods which allow freeform fabrication of macroscopic Zn-air electrochemical batteries. Freedom of geometric design may allow for new possibilities in performance optimization. Design/methodology/approach – The authors have formulated battery materials which are compatible with solid freeform fabrication (SFF) while retaini...

Background Infant feeding may consist of direct breastfeeding (DBF), pumping and bottle feeding (P&F), formula feeding (FF), solid food feeding (SFF), and any combination. An accurate evaluation of infant feeding requires descriptions of different patterns, consistency, and transition over time. Methods In United States of America, the Infant Feeding Practice Study II collected information on...
