An intelligent system is a that can automatically adapt changing environments varying process requirements minimal supervision assistance from operators. Therefore, become recognized core high technology enhance ove...

Abstract Deviations between nominal and actual tolerances are a challenging problem during turning processes of thin-walled workpieces. One main cause these deviations is the clamping force applied by chuck to hold workpiece. Due low stiffness workpieces, large workpiece deformations can occur even when forces low. For this reason, needs be precisely adjusted. A possible approach chucks with in...

Magneto-optical traps (MOTs) are widely used for laser cooling of atoms. We have developed a high-flux compact cold-atom source based on pyramid MOT with unique adjustable aperture that is highly suitable portable quantum technology devices, including space-based experiments. The adjustability enabled an investigation into the previously unexplored impact size atomic flux, and optimisation allo...

This paper presents the design and development of a miniature integrated jumping running robot that can adjust its route trajectory has passive self-righting. The mechanism was developed by using novel strategy combines hard-bodied animal (springtail) soft-bodied (gall midge larvae) locomotion. It could reach height about 1.5 m under load 98.6 g 1.2 156.8 g. To enhance flexibility robot, clutch...

double layer zno/sno2 thin film resistive gas sensors were fabricated by successive pvd of those oxides onto porcelain substrates. the metallic contacts were provided by electron beam evaporation of platinum onto substrates prior to deposition of the gas sensitive layers. deposits were thermally annealed at different temperatures. it was shown that the activation energy of electrical conduction...

The design of infrastructure used for deploying water quality sensors can potentially impact data quality. Despite this, sensor has not been well discussed in the peer-reviewed literature. Here, we present side-by-side measurements from two contrasting designs; a “monopod” consisting strut driven into streambed and downrigger suspended an “overhead cable.” We collected over approximately 6-mont...

Reconfigurable intelligent surfaces (RISs) appear as one of the most promising paradigms for future wireless communications, because their high adjustability diverse communication demands and additional information-carrying capability by reflecting patterns. This paper investigates capacity RIS-assisted multiple-input multiple-output (MIMO) symbiotic communications utilizing multiple patterns, ...

Thin metallic films on dielectric nanospheres are demonstrated to have a high potential for fabrication of cost-effective SERS substrates. In addition the morphological advantages that offer attaining density hot-spots, possessing shape adjustability by uncomplicated thermal treatment make them an attractive platform tuneable Furthermore, when combined with oblique angle metal deposition techni...

Bird strikes are a predominant threat to aviation safety, especially in airport airspace. Effective wildlife surveillance methods required for the harmonious coexistence of management and friendly ecology. Existing works indicate close relationship between bird activities weather. The relevance activity weather is favorable intuitive understanding ecological environments providing constructive ...

BACKGROUND Sonographers' perceptions of ergonomic and work-related pain problems at work have so far mostly been researched in quantitative studies by questionnaires. There is a need of experience-based research to deepen the knowledge about how sonographers perceive ergonomic problems at work. Therefore, the aim of this qualitative study was to describe sonographers' perceptions of ergonomic p...
