A Study of Digital Architecture Talent Development Based on the Workcamp Model
Digital architecture is a trend that can not be ignored in today's construction industry, and the development of digital technology has had a far-reaching impact on the traditional construction industry. The cultivation of digital architecture talents has become an important issue in the field of architecture education. In this paper, we take the demand for talent in the construction industry and the development trend of digital architecture as the background, explore the teaching mode and characteristics of the work camp, and put forward a set of digital architecture talent cultivation strategies based on the work camp mode. Through the combination of theoretical analysis and practical operation, it provides certain reference significance for the cultivation of digital architecture talents
Using Experience Classification for Training Non-Markovian Tasks
Unlike the standard Reinforcement Learning (RL) model, many real-world tasks
are non-Markovian, whose rewards are predicated on state history rather than
solely on the current state. Solving a non-Markovian task, frequently applied
in practical applications such as autonomous driving, financial trading, and
medical diagnosis, can be quite challenging. We propose a novel RL approach to
achieve non-Markovian rewards expressed in temporal logic LTL (Linear
Temporal Logic over Finite Traces). To this end, an encoding of linear
complexity from LTL into MDPs (Markov Decision Processes) is introduced to
take advantage of advanced RL algorithms. Then, a prioritized experience replay
technique based on the automata structure (semantics equivalent to LTL
specification) is utilized to improve the training process. We empirically
evaluate several benchmark problems augmented with non-Markovian tasks to
demonstrate the feasibility and effectiveness of our approach
Stacking Dependent Optical Conductivity of Bilayer Graphene
The optical conductivities of graphene layers are strongly dependent on their
stacking orders. Our first-principle calculations show that while the optical
conductivities of single layer graphene (SLG) and bilayer graphene (BLG) with
Bernal stacking are almost frequency independent in the visible region, the
optical conductivity of twisted bilayer graphene (TBG) is frequency dependent,
giving rise to additional absorption features due to the band folding effect.
Experimentally, we obtain from contrast spectra the optical conductivity
profiles of BLG with different stacking geometries. Some TBG samples show
additional features in their conductivity spectra in full agreement with our
calculation results, while a few samples give universal conductivity values
similar to that of SLG. We propose those variations of optical conductivity
spectra of TBG samples originate from the difference between the commensurate
and incommensurate stackings. Our results reveal that the optical conductivity
measurements of graphene layers indeed provide an efficient way to select
graphene films with desirable electronic and optical properties, which would
great help the future application of those large scale misoriented graphene
films in photonic devices.Comment: 20 pages, 5 figures, accepted by ACS Nan
