In modular construction projects, unit production and onsite work are conducted concurrently, enabling shorter duration, lower cost, improved quality. Because of the nature work, building design details should be determined early in phase, which requires information from participants. However, process for stick-built does not include such information, leads to errors design, as omissions conflicts participants, causing reworking phase. To reduce errors, an flow identified representing...

Silicon nanowires have used the development of sensitive chemical biosensors....

The rise in single-person households has resulted social problems like loneliness and isolation, commonly known as "death by loneliness." Various factors contribute to this increase, including a desire for independent living communication challenges within families due societal changes. Older individuals alone are particularly susceptible isolation limited family lack of activities. Addressing these issues is crucial, proactive solutions needed. It important explore diverse measures tackle...

A novel design for a chip-scale miniature oven-controlled crystal oscillator (OCXO) is presented. In this design, all the main components of an OCXO--consisting oscillator, temperature sensor, heater, and temperature-control circuitry--are integrated on single CMOS chip. The OCXO package size can be reduced significantly with because resonator does not require separate most circuitry Other characteristics such as power consumption warm-up time are also improved. Two different types quartz...
