Generally, the 3ω method for the measurement of fluid thermal properties is based on an approximate solution to heat conduction model assuming vanishing heater-thickness, no dielectric layer and infinite heater-length. In this study, a novel three-dimensional model and partial differential equations of the dimensionle…
The polymeric industry handles Tetrafluoroethylene (TFE) as basic material for polymer (PTFE) and co- polymer (PCTFE) production. As a chemically unstable gas, it can react in an explosive way, without the presence of any other gases. Once initiated such an exothermic reaction can propagate through the pipe system of…
This paper proposes a combination of annular copper and cylindrical copper as the TSV conductor to decrease the effect of thermal mismatch between copper and silicon in MEMS packaging, which results in a reliability risk between redistribution layer (RDL) and TSV. There are three important factors which may have the m…
Determination of the annealing condition has always been critical and challenging for performance improvement of the carbon-based devices. In this paper, rapid thermal annealing (RTA) in hydrogen followed by rapid cooling down with a double-thermal-region movable furnace for carbon nanotube thin film transistors (CNT-…
L’acétylation est une modification post-traductionnelle des protéines essentielles. Elle est impliquée dans bon nombre de processus cellulaires importants comme la régulation de la structure de la chromatine et le recrutement de protéines. Deux groupes d’enzymes, soient les lysines acétyltransférases et les lysines dé…
The Lamb waves and horizontal shear waves' propagation in LiTaO3thin plate is investigated as a function of Euler angles. Both velocity and electromechanical coupling factor largely depend on the plate's thickness. Around (0°, 30°, 0°), LiTaO3thin plate has a high velocity and a suitable coupling factor for a high fre…
O fenômeno da transferência simultânea de calor e massa presente nos absorvedores das máquinas de refrigeração por absorção foi estudado pela Técnica da Transformada Integral Generalizada, GITT, do inglês, Generalized Integral Transform Technique, para três casos de interesse prático com crescente grau de dificuldade…
In this paper we present a holistic wafer-level manufacturing process for nanoscopic sensor devices based on individualized single-wall carbon nanotubes (SWCNTs) integrated in MEMS. The fabrication technology is demonstrated in detail. Moreover, a first application in form of a MEMS test stage for SWCNT strain and rel…
Patients who undergo spine surgery can have suboptimal outcomes postoperatively from pseudarthrosis. Historically, iliac crest bone graft, which provides all of the critical elements of bone repair, has been the gold standard for spine fusion, however, recent studies suggest that less than 6% of the U.S. spine surgeon…
In this work a Nd doped PG with high Tg and high refractive index was manufactured and used to produce a core/cladding rod structure, using a cladding passive PG composition with compatible thermo-mechanical properties. The optical and fluorescence properties of the active glass resulted to be comparable to those of c…
Toluene nitration with mixed acid is a very complex process, because there are many reactions involved in the nitrotoluene production process, such as mononitration as a main reaction, dinitration, trinitration, oxidization, and decomposition of products as side reactions. Therefore, it is difficult to calculate an ac…
Abstract An der Universität Siegen werden in Zusammenarbeit mit Fotoverbundglas Marl GmbH neuartige Glas‐Polycarbonat‐Verbundtafeln entwickelt. Verglichen mit üblichen Verbundsicherheitsgläsern ist eine Steigerung der Leistungsfähigkeit der Verbundtafeln durch ein innovatives Herstellungsverfahren und die Verwendung i…
P ropeller shaft merupakan salah satu bagian terpenting dari instalasi penggerak kapal. Model propeller shaft dibuat dengan material dasar paduan aluminium 6063 melalui proses pengecoran. HPDC ( High Pressure Die Casting ) merupakan salah satu metode dalam proses pengecoran yang memiliki banyak kelebihan dibandingkan…
An electric field distribution in a top electrode plane/periodical poled (PP) plate/bottom electrode plane looks like a cross-field model (by Smith) of an interdigital transducer (IDT) to generate a surface acoustic wave (SAW). Therefore, this structure has the possibility to generate an acoustic wave. This structure…
Traditional virtual clothing prototyping is achieved by wrapping 2D pattern pieces on virtual mannequins. This paper describes a reverse approach that develops 3D garments first and unwraps 2D pattern pieces out of them. To achieve this, a 3D drawing board for men’s upper body outerwear was developed from bodyscan dat…
El objetivo de este trabajo es el estudio experimental de la influencia del material del portaherramientas en la estabilidad dinámica durante el fresado de superficies inclinadas de acero para trabajos en frío AISI D6. La evaluación de la estabilidad dinámica se basó en el análisis de los espectros de frecuencia de la…
A planar dual band antenna with wideband characteristics using metamaterial (MTM) is proposed in this paper. Stepped impedance resonator (SIR) inspired metamaterial is loaded in the patch of the antenna. SIR metamaterial is different from conventional composite right left handed (CRLH) metamaterial as it doesn't reali…
Cryopreservation of PBMC (peripheral blood mononuclear cells) was done to preserve and analyze the number of PBMC derived from blood samples which come in at different time. The batch analysis wasperformed at the same time in order to reduce variations in results. The analysis on the cells numbers carried out after 1,…
A triple band, planar antenna using composite right/left-handed (CRLH)metamaterial (MTM) is presented in this paper. Proposed antenna produces zeroth order resonance (ZOR) at 1.04 GHz. Composite MTM behavior is obtained from series gap taken in patch, meander line inductor, complementary slot rings, rectangular stub a…
In this paper the evolution of microstructures and its impact in Al-ZnO as deposited thin film on different substrates such as Si, SiO2, Polyimide, Glass by using DC sputtering at 400W in presence of argon flow 30 sccm are investigated. The XRD of the films suggests that the deposited films are polycrystalline hexagon…
