Film “Huma Amas” ini bertujuan menyuarakan isu di Kalimantan Timur yaitu lingkungan dan kecil khususnya daerah sekitar tambang batubara.Karya visualisasinya menggunakan kedalaman ruang (depth of field) berbeda-beda sebagai representasi k...

The present work shows the results obtained from experimental investigations of the augmentation of turbulent flow heat transfer in a horizontal tube by means of mesh inserts with air as the working fluid. Sixteen types of mesh inserts with screen diameters of 22mm, 18mm, 14mm and 10mm for varying distance between the screens of 50mm, 100mm, 150mm and 200mm in the porosity range of 99.73 to 99....

The operational cost of 300mm wafer production is significantly greater than that of 200mm fabs. Real-time monitoring of product can save time and money through reduced scrap and decreased cycle time. Current process monitoring generally incorporates stand-alone metrology, which is time consuming and requires excessive wafer handling by production operators. The benefits of integrated metrology...

Gomphonema, a freshwater diatom, is currently being studied to determine its effect on the capacity of hydroelectric canals and the structure of turbulent boundary layers. Gomphonema is the primary fouling organism present in Tarraleah No.1 Canal (operated by Hydro Tasmania) and was found to cause a 10% reduction in flow carrying capacity. Filamentous algae streamers up to 200mm long have also ...

We present a simple device for multiplex quantitative enzyme-linked immunosorbant assays (ELISA) made from a novel melt-extruded microcapillary film (MCF) containing a parallel array of 200mm capillaries along its length. To make ELISA devices different protein antigens or antibodies were immobilised inside individual microcapillaries within long reels of MCF extruded from fluorinated ethylene ...

This paper presents the design, fabrication and characterisation of InGaAs–InAlAs high electron mobility transistors (pHEMTs) suitable for low-frequency LNA designs. Very low levels of leakage, in the order of 0.05A/cm, are demonstrated by the pHEMTs, which have enabled the implementation of large-geometry, low-noise devices. Transistors with gate widths ranging from 200mm to 1.2mm are demonstr...

An electro-conjugate fluid (ECF) is a kind of functional fluid, which produces a jet flow (ECF jet) when subjected to high DC voltage. This study introduces the ECF jet to develop a novel inchworm like in-pipe mobile robot which mainly consists of two clamping units (a clamping actuator, an ECF jet generator and an ECF tank) and a propelling unit (a propelling actuator, an ECF jet generator and...

This paper presents the design of a compact rectangular dielectric resonator antenna (RDRA) for wireless applications. A metal plate has been attached to top surface of the RDRA to achieve significant reduction in the resonant frequency of the antenna. A simple microstrip feeding mechanism has been used to excite this compact rectangular DRA. Performance parameters such as resonant frequency, i...
