rectangular waveguide (wr) is one of the earliest types of transmission lines. rectangular waveguide can be produced by hot extrusion process. in this paper, the hot extrusion process of cuzn5 rectangular waveguide was investigated by finite element method (fem). in addition, genetic algorithm method (ga) was used to optimize the die geometry and process conditions to achieve the lowest magnitu...

This paper presents an individually addressable 32x32 microelectrode array (MEA) system with built-in CMOS potentiostat for analyzing single droplets and ultra-small volume samples. The proposed system has advantages of smaller sample requirement, higher density, small form factor, low power and higher sensitivity and advanced functionality over the conventional electrode array. Each electrode ...

HYPOTHESIS Passive, active, and historical suicidality are associated with preference for death over disability. DESIGN Community nonpatients without pain, community patients with pain, and patients with acute and chronic pain were compared for endorsement of disability perception and preference for death over disability. Phi correlations and chi-square analyses were calculated between prefer...

The achieved results are inspired by the paper of Seiffert (Die Wurzel, ...

During tube hydroforming process, the friction conditions between and die have a great importance on material plastic flow distribution of residual stresses final component. Indeed, three-dimensional finite element model process in case square section has been performed, using dynamic static approaches, to study effect both induced by process. First, comparative numerical experimental results c...

These impedance conditions correspond to the class F operating condition, the ideal voltage and current shapes for which are shown in Figure 1. Here a sum of odd harmonics produces a square voltage waveform and a sum of even harmonics approximates a half-sinusoidal current shape. In reality, both extrinsic and intrinsic transistor parasitic elements have a substantial effect on the efficiency, ...

The processor uses a set of ten custom VLSI chips fabricated in HP's high-performance NMOS-III technology. The chip implements all 140 of containing architecture's instructions on an 8.4-mm-square die containing 115,000 transistors. ing ten complex chips concurrently takes more than a casual approach to organization and planning. It's capable of supporting multiple users CAD technical HP-UX app...

India is a vast country and is larger than the whole of Western Europe. On its 1 620 000 square miles of land over 650 000 000 people live and die. The population is believed to be increasing at a rate of more than 13 millions each year. There are over 220 different languages and many different communities and cultures, all of which are responsible for the colourful and exciting life of the nat...

Deep drawing process is one of the most applicable methods in producing industrial parts. In this process, the initial blank deforms to final product using a rigid punch and die. In this investigation, the effect of deep drawing process parameters of brass/steel laminated sheet composites on required forming force has been investigated. The process simulated using finite element method (FEM) an...

Square is a multivariate quadratic encryption scheme proposed in 2009. It is a specialization of Hidden Field Equations by using only odd characteristic elds and also X as its central map. In addition, it uses embedding to reduce the number of variables in the public key. However, the system was broken at Asiacrypt 2009 using a di erential attack. At PQCrypto 2010 Clough and Ding proposed two n...
