Gambang's existence which is getting dimmer, has made the writer call to make it writing in organology studies. As a native of region, author feels he responsibility life Gambang art. This organological study aims become written document process making xylophones; when people want learn xylophones, they can see this article. Thus also reducing fear threat extinction xylophone. paper uses descri...

Abstract Although type Ia supernovae (SNe Ia) are very important in many astrophysical fields, such as cosmology, their explosion mechanisms and progenitor systems still remain unclear. In physics, the relative equivalent width (REW) of Si ii 635.5 nm absorption feature reflects velocity interval silicon SN ejecta, which may then provide constraints on SNe Ia. this paper, we divide into broad-l...

A lighting controls study performed over a three month period provided data that can be used to determine the impact of manual switching and dimming controls on occupant behavior and attitudes and on energy use. Data were analyzed for 58 private offices on a single floor of a modern office building in Boulder, Colorado. Each office was equipped with a ceiling-mounted infrared motion sensor, a d...

Background. With a projected rise in the procurement of home automation systems, we experimentally investigate security risks that homeowners might be exposed to by compact fluorescent lamps (CFL), where the lamps themselves do not have network capabilities but are controlled by compromised Internet-enabled home automation systems. Aim. This work seeks to investigate the feasibility of causing ...

It is of prime importance to recognize evolution and extinction effects in supernovae results as a function of redshift, for SN Ia to be considered as distance indicators. This review surveys all observational data searching for an evolution and/or extinction , according to host morphology. For instance, it has been observed that high-z SNe Ia have bluer colours than the local ones: although th...
