New dispatching rules and due date assignment models for dynamic job shop scheduling problems
(Inderscience Enterprises Ltd., 2018)In this paper, new due date assignment models and dispatching rules have been designed for the dynamic job shop scheduling problem. All of them have competitive results compared to the models from previous studies. The ... -
( Potentiometric and spectrophotometric determination of fluoride in some natural waters of Dogubayazit region). [Dogubayazit yoresindeki bazi su kaynaklarinda spektrofotometrik ve potansiyometrik yontemerle fluorur miktarlarinin arastirilmasi.]
(1983)Seventeen samples, out of 23, contained fluorides higher than recommended control limits for fluorides in drinking waters by WHO. It has been reported by many workers who studied in the area for the last 10 yr, that dental ... -
Quantitative determination of escin. A comparative study of HPLC and TLC-densitometry
(1994)Escin was quantitatively determined by both HPLC and TLC-densitometric techniques in horse-chestnut extracts. The results were found to be accurate, reproducible and in excellent agreement. -
Some physical effects of reaction rate on PbS thin films obtained by chemical bath deposition
(Elsevier Science BV, 2013)Thin films of polycrystalline lead sulfide (PbS) have been deposited on glass substrates at 303 +/- 1 K using chemical bath deposition (CBD). The precipitation of PbS on solid surfaces under four different reaction conditions ... -
Strained band edge characteristics from hybrid density functional theory and empirical pseudopotentials: GaAs, GaSb, InAs and InSb
(IOP Publishing LTD, 2016)The properties of a semiconductor are drastically modified when the crystal point group symmetry is broken under an arbitrary strain. We investigate the family of semiconductors consisting of GaAs, GaSb, InAs and InSb, ... -
Theoria, praxis, poiesis: A continuum scheme
(2011)The present age provides that the new production technologies are in a continuous experimental production in terms of both quantitative and rapidness criteria. Thinking and testing speed comes closer with these experiences. ... -
U-type assembly line balancing with ergonomic factors for balance stability [Sürdürülebi·li·r denge i·çi·n ergonomi·k faktörleri· i·çeren u-ti·pi· montaj hatti dengelemesi·]
(2012)In this paper, we present a new mathematical model of U-type assembly line balancing problem based on the performance factors of the operators, the amount of energy used and incompatibility between the tasks. Many researchers ...
