Various joining methods are available for composite structures, with anticipated benefits for the most obvious way of exploiting the nature of thermoplastic materials: melting and reconsolidation. A proper joint selection and detailed design, however, will require quantitative results obtained in an objective and reproducible procedure. The objective of this paper was to develop benchmark proce...

resistance spot welding is an important manufacturing process in the automotive industry for assembling bodies. the quality and strength of the welds and, by extension, the body is mainly defined by the quality of the weld nuggets. the most effective parameters in this process are sheet material, geometry of electrodes, electrode force, current intensity, welding time and sheet thickness. the p...

Abstract Zn–Al–Mg coating galvanized steel in resistance spot welded (RSW) different configurations of DC51D was investigated to illustrate the nugget evolution process and mechanical properties joints. Results show that microstructure joints can be divided into zone (FZ), heat-affected (HAZ), base metal (BM). FZ composed lath martensite. The average hardness value weld joint 110 HV 0.2 while u...

Daging ayam merupakan salah satu hasil ternak yang harganya relatif terjangkau dan memiliki kandungan gizi bagus. dapat diolah menjadi aneka olahan, seperti sosis, nugget, bakso. Nugget adalah produk dengan bahan baku daging ayam. Produk ini berupa resctructed meat macam-macam sesuai keinginan, dipadu sedikit tepung kemudian diselimuti panir, sehingga rasanya sangat diminati oleh semua kalangan...

For many expensive deterministic computer simulators, the outputs do not have replication error and the desired metamodel (or statistical emulator) is an interpolator of the observed data. Realizations of Gaussian spatial processes (GP) are commonly used to model such simulator outputs. Fitting a GP model to n data points requires the computation of the inverse and determinant of n × n correlat...

A novel pelage color variant appeared in a laboratory colony of white-footed mice (Peromyscus leucopus) from Massachusetts. The mature adult coat color of this variant exhibits a rich golden tan appearance on the dorsum with white underparts. The trait is inherited as an autosomal recessive. Phenotypic comparisons with other rodents suggest that the trait is attributable to an allele at the bro...

A Robotic System is being developed to automate the crucible packing process in CZ semiconductor wafer production. It requires the delicate manipulation and packing of highly irregular polycrystalline silicon nuggets, into a fragile fused silica crucible. For this application, a dual optical 3-D surface geometry measuring system that uses active laser triangulation has been developed and succes...
