By taking into account surface transition layers (STL), the dielectric properties of ferroelectric thin films described by the transverse Ising model are discussed in the framework of the mean field approximation. Functions of the intra-layer and inter-layer couplings are introduced to characterize STL, which makes the model more realistic compared to previous treatment of surface layers using ...

This scientific paper will cover the process of creating two 3D objects, accompanied by a brief history printing technology, designing model in CAD software, saving appropriate format supported printer, features technology and materials from which object can be made examples where products created applied. The models was studio "Xtrude Design & Print" Skopje. Two have been printed. A creati...

The purpose of this work is to evaluate the surface roughness (Ra) of the customised bone implant fabricated by Selective Laser Sintering (SLS). Computer Tomography (CT) scan data of the femur bone was taken for the study. The scan data was converted to .stl file format. Taguchi’s design of experiments was conducted to fabricate the customised implants using SLS. The quantitative measures of su...

We present an overview of the HPC++ Parallel Standard Template Library (PSTL), a parallel version of the C++ Standard Template Library (STL). The PSTL is part of HPC++, a C++ library and language extension framework being developed by the HPC++ consortium as a standard model for portable parallel programming in C++. The PSTL includes distributed versions of the seven STL containers (vector, lis...

We present a mathematical programming-based method for model predictive control of cyber-physical systems subject to signal temporal logic (STL) specifications. We describe the use of STL to specify a wide range of properties of these systems, including safety, response and bounded liveness. For synthesis, we encode STL specifications as mixed integer-linear constraints on the system variables ...

The biosynthetic route for epoxyangelate esters of the sesquiterpene lactones (STL) uvedalin and enhydrin from in vitro cultures of Smallanthus sonchifolius (Asteraceae) was investigated with (13)C-precursors for the first time in the literature. Photomicroscope analyses and studies using MALDI-MS imaging confirmed that glandular trichomes accumulate STL.

This study evaluated the feasibility of utilizing a 3D-printed anthropomorphic patient-specific head phantom for patient-specific quality assurance (QA) in intensity-modulated radiotherapy (IMRT). Contoured left and right head phantoms were converted from DICOM to STL format. Fused deposition modeling (FDM) was used to construct an anthropomorphic patient-specific head phantom with a 3D printer...

Manufacturing of any product involves not only in design and material selection but also selection of appropriate manufacturing process required to obtain the desire shape and properties of the product. Prototyping is a process of structure pre-production models of a product to test various aspects of its design. Rapid Prototyping (RP) techniques are methods that allow to quickly producing phys...

Accurate temperature prediction is of great significance to human life and social economy. A series traditional methods machine learning have been proposed achieve prediction, but it still a challenging problem. We propose model that combines seasonal trend decomposition using loess (STL) the bidirectional long short-term memory (Bi-LSTM) network high-accuracy daily average China cities. The de...

In general, a software for Rapid Prototyping (RP) has to read the part geometry in STL (STereoLithography) format, slice it electronically, generate information for layer addition and send these data to the RP machine. This work presents the development of a RP software to achieve that. The main objectives are to obtain autonomy on the processing parameters and to develop a system which could b...
