Design for the past
The thesis project started off with an investigation of the Coal Gas Factory in Datong City, and an interview of a former factory employee. All relevent information is covered in the Report.
This thesis project proposes for an alternative factory design solution for the past (1980s), acknowledging its inevitable failure in its future (2000s).
The design acknowledges architecture’s nature of temporality, and is focused on making architecture transformative--creating space and environment for architecture to be transformed in order to accommodate updated programs and activities when its no longer able to serve its original purpose
A Universal Update-pacing Framework For Visual Tracking
This paper proposes a novel framework to alleviate the model drift problem in
visual tracking, which is based on paced updates and trajectory selection.
Given a base tracker, an ensemble of trackers is generated, in which each
tracker's update behavior will be paced and then traces the target object
forward and backward to generate a pair of trajectories in an interval. Then,
we implicitly perform self-examination based on trajectory pair of each tracker
and select the most robust tracker. The proposed framework can effectively
leverage temporal context of sequential frames and avoid to learn corrupted
information. Extensive experiments on the standard benchmark suggest that the
proposed framework achieves superior performance against state-of-the-art
trackers.Comment: Submitted to ICIP 201
Normalized ground states for a biharmonic Choquard system in
In this paper, we study the existence of normalized ground state solutions
for the following biharmonic Choquard system \begin{align*}
\begin{split}
\left\{
\begin{array}{ll}
\Delta^2u=\lambda_1 u+(I_\mu*F(u,v))F_u (u,v),
\quad\mbox{in}\ \ \mathbb{R}^4,
\Delta^2v=\lambda_2 v+(I_\mu*F(u,v)) F_v(u,v),
\quad\mbox{in}\ \ \mathbb{R}^4,
\displaystyle\int_{\mathbb{R}^4}|u|^2dx=a^2,\quad
\displaystyle\int_{\mathbb{R}^4}|v|^2dx=b^2,\quad u,v\in H^2(\mathbb{R}^4),
\end{array}
\right.
\end{split}
\end{align*} where are prescribed, , with , are
partial derivatives of and have exponential subcritical or
critical growth in the sense of the Adams inequality. By using a minimax
principle and analyzing the behavior of the ground state energy with respect to
the prescribed mass, we obtain the existence of ground state solutions for the
above problem.Comment: arXiv admin note: text overlap with arXiv:2211.1370
Normalized solutions for a fractional -Laplacian Choquard equation with exponential critical nonlinearities
In this paper, we are concerned with the following fractional -Laplacian
Choquard equation
\begin{align*}
\begin{cases}
(-\Delta)^s_{N/s}u=\lambda |u|^{\frac{N}{s}-2}u +(I_\mu*F(u))f(u),\ \
\mbox{in}\ \mathbb{R}^N,
\displaystyle\int_{\mathbb{R}^N}|u|^{N/s} \mathrm{d}x=a^{N/s},
\end{cases}
\end{align*} where , is a
prescribed constant, ,
with , is the primitive function of , and is a
continuous function with exponential critical growth of Trudinger-Moser type.
Under some suitable assumptions on , we prove that the above problem admits
a ground state solution for any given , by using the constraint
variational method and minimax technique
Normalized ground states for a biharmonic Choquard equation with exponential critical growth
In this paper, we consider the normalized ground state solution for the
following biharmonic Choquard type problem \begin{align*}
\begin{split}
\left\{
\begin{array}{ll}
\Delta^2u-\beta\Delta u=\lambda u+(I_\mu*F(u))f(u),
\quad\mbox{in}\ \ \mathbb{R}^4,
\displaystyle\int_{\mathbb{R}^4}|u|^2dx=c^2,\quad u\in H^2(\mathbb{R}^4),
\end{array}
\right.
\end{split}
\end{align*} where , , ,
with , is the primitive function
of , and is a continuous function with exponential critical growth in
the sense of the Adams inequality. By using a minimax principle based on the
homotopy stable family, we obtain that the above problem admits at least one
ground state normalized solution.Comment: arXiv admin note: text overlap with arXiv:2210.0088
The Implementation of Central Bank Policy in China: The Roles of Commercial Bank Ownership and CEO Faction Membership
We examine the roles of bank ownership and CEO political faction membership in facilitating or hindering the implementation of central bank policy in China. Specifically, we examine the response of China's commercial banks to People's Bank of China (PBC) guidelines intended to decrease mortgage lending and to slow down the rise in residential property prices. We find that both bank ownership and faction membership matter. Central government-owned banks whose CEOs are members of the specialist finance faction within the Chinese Communist Party (CCP) respond most strongly to PBC guidance, whereas provincial or city government-owned banks whose CEOs are members of a generalist faction respond least strongly. The implementation of PBC policy has real effects: in those cities where central government-owned banks with specialist CEOs constitute a larger percentage of total bank branches, house prices grew more slowly, as did the number of residential real estate transactions and the number of new listings. Where in contrast provincial and city government-owned banks with generalist CEOs dominate, the number of transactions grew faster; the rate of house price appreciation and the number of listings were however unaffected. We conclude that China's different levels of government and the CCP's different factions enjoy some discretion in responding to PBC guidance and that they exploit the discretion they are afforded to vary the strength of their response
Normalized solutions for a fractional Choquard-type equation with exponential critical growth in
In this paper, we study the following fractional Choquard-type equation with
prescribed mass
\begin{align*}
\begin{cases}
(-\Delta)^{1/2}u=\lambda u +(I_\mu*F(u))f(u),\ \ \mbox{in}\ \mathbb{R},
\displaystyle\int_{\mathbb{R}}|u|^2 \mathrm{d}x=a^2,
\end{cases}
\end{align*} where denotes the -Laplacian operator,
, , with
, is the primitive function of , and is a
continuous function with exponential critical growth in the sense of the
Trudinger-Moser inequality. By using a minimax principle based on the homotopy
stable family, we obtain that there is at least one normalized ground state
solution to the above equation.Comment: arXiv admin note: text overlap with arXiv:2211.1370
