One of the most prominent trajectory-level task models applied is Dynamic Movement Primitives (DMP). However, it lacks the ability to tackle complex operations as often encountered in industrial assembly. Augmenting low-level models with a high-level framework in which different movement segments are deliberately parameterised is considered promising for such scenarios. This paper investigates the combination of trajectory-level DMPs with Methods-Time Measurement (MTM). We demonstrate how the MTM-1 system is utilised to establish distinguished DMP models for five of its basic elements, paving the way to benefitting from the sophisticated MTM system. The evaluation of the framework is conducted on a generic pick and place operation. Compared to a one-model-fits-all DMP approach for the whole task, the proposed method shows the advantage of appropriate temporal scaling, accuracy levelling and force consideration at adequate times. 2023-01-01T00:00:00Z http://hdl.handle.net/10453/197295 Title: Evaluating chloride durability of low-carbon concrete: insights from accelerated testing and tidal simulation Authors: Yang, Y; Thomas, P; Sirivivatnanon, V 2026-10-21T00:00:00Z http://hdl.handle.net/10453/197294 Title: From prescriptive to performance requirements: carbonation coefficient as a durability indicator Authors: Vasikova, I; Thomas, P; Sirivivatnanon, V Abstract: Current durability specifications largely rely on prescriptive requirements where carbonation resistance is indirectly controlled by mixture composition. This paper discusses the potential of the carbonation coefficient (k) to serve as a performance-based indicator for carbonation resistance and proposes accelerated carbonation testing as a practical verification method. Experimental evidence demonstrates that carbonation coefficients can be reliably determined for different low-carbon concrete systems and correlate strongly with compressive strength, providing a pathway towards future performance-based durability requirements. 2026-10-21T00:00:00Z http://hdl.handle.net/10453/197293 Title: Updating durability requirement of low carbon concrete in Australian standards Authors: Sirivivatnanon, V; Jiminez, A; Vasikova, I; Yang, Y; Thomas, P Abstract: There are 2 broad types of low carbon concrete in Australia. The first is concrete with high SCM such as fly ash or blast furnace slag and the second is the alkali activated binder concrete. They are specified to AS 3600 or AS 5100.5 and TS199 respectively. With the rapid adoption of low carbon concrete, the durability requirements in AS 3600 and AS 5100.5 are reviewed with respect to carbonation and chloride-induced corrosion. In this paper, the carbonation resistance and sorptivity of a range of low carbon concretes are examined justifying the changes in concrete cover requirements for the 50-year and 100-year design life of low carbon concrete structures. The resistance to chloride penetration and the required service life are examined by compliant to Transport for New South Wales B80 specifications and CCAA’s long-term field performance findings. NSW Government’s recommended specifications of the embodied carbon of low carbon concretes are presented and shown in relation to GCCA’s low carbon and near zero carbon ratings. 2026-10-21T00:00:00Z
