Rangka batang (truss) adalah sistem struktural yang terdiri dari sejumlah bagian (batang), masing-masing diyakini bertindak sebagai sambungan pada simpulnya dan hanya dapat menahan gaya aksial. Pengukuran gaya-gaya rangka sederhana (truss apparatus) merupakan salah satu modul dalam Praktikum Fenomena Dasar Mesin. ini bertujuan agar mahasiswa mampu memahami perhitungan parameter-parameter pentin...

We discuss the behavior of free perfect staggered fermions and truncated versions thereof. The study includes flavor non-degenerate masses. We suggest a new blocking scheme, which provides excellent locality of the perfect lattice action. A truncation procedure adequate for the structure of staggered fermions is applied. We consider spectral and thermodynamic properties and compare truncated pe...

We construct a perfect lattice action for staggered fermions by blocking from the continuum. The locality, spectrum and pressure of such perfect staggered fermions are discussed. We also derive a consistent fixed point action for free gauge fields and discuss its locality as well as the resulting static quark-antiquark potential. This provides a basis for the construction of (classically) perfe...

We perform a comparative study of the infrared properties of overlap and staggered fermions in QCD. We observe that the infrared spectrum of the APE/HYP improved staggered Dirac operator develops a four-fold near-degeneracy and is in quantitative agreement with the infrared spectrum of the overlap operator. The neardegeneracy allows us to identify the zero modes of the staggered operator and we...

Recent studies suggest that the softerror rate in microprocessor logic is likely to become a serious reliability concern by 2010. Detecting soft errors in the processor’s core logic presents a new challenge beyond what error-detecting and correcting codes can handle. Currently, commercial microprocessor systems that require an assurance of reliability employ an error-detection scheme based on d...

The subconscious influence of framing on perceptions of political issues is well-document in political science and communication research. A related line of work suggests that drawing attention to framing may help reduce such framing effects by enabling frame reflection, critical examination of the framing underlying an issue. However, definite guidance on how to identify framing does not exist...
