Microfluidic devices are gaining popularity in a variety of applications, ranging from molecular biology to bio-defense. However, the widespread adoption of this technology is constrained by the lack of efficient and cost-effective manufacturing processes. This paper focuses on the roller imprinting process, which is being developed to rapidly and inexpensively fabricate micro-fluidic devices. ...

The pecan separator machine made to facilitate speed up breaking fruit order increase work efficiency hope can achieve high form good yields. purpose this help community processing maximum its production, also productivity fruit, which improve community's economy. research method applied study experiment...

Despite the advanced technologies of battery back-up for heart-lung consoles and the availability of system-wide generators, electromechanical failure is still occurring. Several heart-lung machine manufacturers still provide unsafe handcranking devices to use in the case of an emergency while using a roller blood pump. A new design has been engineered to eliminate safety and quality issues for...

In this paper, we describe a hydraulic system design and vehicle dynamic modeling for development of tire roller traction, an essential aspect in the system analysis of tire rollers. Generally, tire rollers are one of the most useful types of machines employed in road construction, technically applied to many construction fields. We also conceptualize a new hydraulic and driving system as well ...

In this paper the mechanical analysis of the film picking forks roller tooth in field -cleaning machine was done. A finite element analysis model was built and used by the non-linear finite element analysis method. It is obtained from the result of post-processing calculation and analysis that according to the Fourth Strength Theory, the maximum equivalent stress on the pole tooth root under th...

Performa atau unjuk kerja bulldozer sangat dipengaruhi oleh kondisi komponen undercarriage. Pada saat beroperasi, track roller menekan dan menggelinding di atas link sehingga terjadi gesekan antara akibatnya kedua permukaan tersebut mengalami keusan. Gesekan keausan merupakan kerugian dalam bentuk kehilangan energi material yang membutuhkan biaya [4]. Oleh karenanya penelitian terhadap laju tin...
