Addition of higher order plate elements to NASTRAN
Two plate elements, the linear strain triangular membrane element CTRIM6 and the higher order plate bending element CTRPLT1, were added to NASTRAN Level 16.0. The theoretical formulation, programming details, and bulk data information pertaining to the addition of these elements are discussed. Sample problems illustrating the use of these elements are presented
A cluster expansion approach to renormalization group transformations
The renormalization group (RG) approach is largely responsible for the
considerable success which has been achieved in developing a quantitative
theory of phase transitions. This work treats the rigorous definition of the RG
map for classical Ising-type lattice systems in the infinite volume limit at
high temperature. A cluster expansion is used to justify the existence of the
partial derivatives of the renormalized interaction with respect to the
original interaction. This expansion is derived from the formal expressions,
but it is itself well-defined and convergent. Suppose in addition that the
original interaction is finite-range and translation-invariant. We will show
that the matrix of partial derivatives in this case displays an approximate
band property. This in turn gives an upper bound for the RG linearization.Comment: 13 page
Frontliner Services In PT Kai Commuter Jabodetabek New Klender Station, East Jakarta
Service excellent will produce satisfaction for customers. Many companis now are providing the best service to get consumers satisfaction. This research is to find out the implementation of service excellent provided by the frontliner officer PT KAI Commuter Jabodetabek at Klender Baru Station in East Jakarta. The research conducted through qualitative method from January to February 2017. Frontliner officer who became the main service at PT KCJ in Klender Baru Station is divided into several parts including: Officer Counters, Announcer, Passager Service and Inside Security Officer (PKD). The results show that PT KCJ has a good service procedure, and also shown through the report that PT KJC has less complaint from the passenger. Nevertheless, service excellent implementation is still facing the obstacles, such as train travel disturbance, queue at the counter, and lack of seats to wait for the train. Suggestions for PT KCJ to add train travel and additional facilities such as seats and gate-in gate-out Machine
Listen, Attend, and Walk: Neural Mapping of Navigational Instructions to Action Sequences
We propose a neural sequence-to-sequence model for direction following, a
task that is essential to realizing effective autonomous agents. Our
alignment-based encoder-decoder model with long short-term memory recurrent
neural networks (LSTM-RNN) translates natural language instructions to action
sequences based upon a representation of the observable world state. We
introduce a multi-level aligner that empowers our model to focus on sentence
"regions" salient to the current world state by using multiple abstractions of
the input sentence. In contrast to existing methods, our model uses no
specialized linguistic resources (e.g., parsers) or task-specific annotations
(e.g., seed lexicons). It is therefore generalizable, yet still achieves the
best results reported to-date on a benchmark single-sentence dataset and
competitive results for the limited-training multi-sentence setting. We analyze
our model through a series of ablations that elucidate the contributions of the
primary components of our model.Comment: To appear at AAAI 2016 (and an extended version of a NIPS 2015

Light anti-nuclei production in pp collisions at =7 and 14 TeV
A dynamically constrained coalescence model based on the phase space
quantization and classical limit method was proposed to investigate the
production of light nuclei (anti-nuclei) in non-single diffractive (NSD) pp
collisions at =7 and 14 TeV. This calculation was based on the final
hadronic state in the PYTHIA and PACIAE model simulations, the event sample
consisted of 1.2 events in both simulations. The PACIAE model
calculated yield of 6.247 in NSD pp collisions at
=7 TeV is well comparing with the ALICE rough datum of 5.456. It indicated the reliability of proposed method in some extent. The
yield, transverse momentum distribution, and rapidity distribution of the , , and in NSD pp collisions at
=7 and 14 TeV were predicted by PACIAE and PYTHIA model simulations.
The yield resulted from PACIAE model simulations is larger than the one from
PYTHIA model. This might reflect the role played by the parton and hadron
rescatterings.Comment: 5 pages, 2 figure
