Description: CV模型是一种重要的图像分割模型,本文针对其收敛速度慢、效率低的缺点提出一种求解CV模型的新方法.首先将CV模型的能量泛函改写成与原来有相同稳定解的总变分公式形式,然后使用对偶公式法求总变分公式的极小值,再在其中引入一速度项以加快模型的收敛速度.新方法一方面克服了梯度下降法要求时间步长小、迭代次数多的缺点,经过较少次的迭代就能收敛,减少了迭代计算的次数-CV model is one of the most important image segmentation model and disadvantage in view of its convergence rate is slow and low efficiency of the proposed a new method for solving the CV model. First, the energy functional of the CV model adapted and had the same stable solution total variational formula, and then use the dual formula method for total variation formula of minimum, and in which introduced a speed to accelerate the convergence speed of the model. New method to overcome the gradient descent method requires small time steps, the number of iterations of the shortcomings of the, after a few times of iteration will converge, reducing the number of iterative computation

Description: In wireless sensor networks, multipath routing is
used to alleviate reliability degradation due to multihop transmissions
over error-prone wireless channels. However, multipath
routing is not energy-efficient, as it requires all the nodes in the
network to always be awake. To prolong the network lifetime
while maintaining a certain reliability performance, we propose
Sleeping Multipath Routing, which selects the minimum number
of disjoint paths to achieve a given reliability requirement and
puts the rest of the network to sleep.

Description: 在一个果园里，多多已经将所有的果子打了下来，而且按果子的不同种类分成了不同的堆。多多决定把所有的果子合成一堆。
每一次合并，多多可以把两堆果子合并到一起，消耗的体力等于两堆果子的重量之和。可以看出，所有的果子经过n-1次合并之后，就只剩下一堆了。多多在合并果子时总共消耗的体力等于每次合并所耗体力之和。
因为还要花大力气把这些果子搬回家，所以多多在合并果子时要尽可能地节省体力。假定每个果子重量都为1，并且已知果子的种类数和每种果子的数目，你的任务是设计出合并的次序方案，使多多耗费的体力最少，并输出这个最小的体力耗费值。
例如有3种果子，数目依次为1，2，9。可以先将1、2堆合并，新堆数目为3，耗费体力为3。接着，将新堆与原先的第三堆合并，又得到新的堆，数目为12，耗费体力为12。所以多多总共耗费体力=3+12=15。可以证明15为最小的体力耗费值。
输入
输入包括两行，第一行是一个整数n(1<＝n<=10000)，表示果子的种类数。第二行包含n个整数，用空格分隔，第i个整数ai(1<＝ai<=10000)是第i种果子的数目。
输出
输出包括一行，这一行只包含一个整数，也就是最小的体力耗费值。输入数据保证这个值小于2^31。-In an orchard, a lot has shot down all the fruit, and the fruit is divided into different types according to different stack. We decided to put all the fruit of a lot of synthetic pile. Every merger, a lot of fruit into two piles can put together, physical consumption equal to the weight of the fruit and piles. As can be seen, all the fruit after n-1 merger, on the left a pile. When you merge a lot of fruit in the total consumption of physical strength equal to the sum of the consumption of each merger. Because it will take great effort to put these fruits to move back home, so a lot of fruit in consolidation to save energy as much as possible. The number of species and the number of each fruit is assumed that each fruit weight is 1, and the fruit is known, your task is to design a combined order of programs to spend a lot of physical minimum, and output value of the minimum physical cost. For example there are three kinds of fruit, followed by the number 1,2,9. 1,2 heap can first merg

Description: Abstract—This paper proposes a new strategy to meet the controllable
heating, ventilation, and air conditioning (HVAC) load
with a hybrid-renewable generation and energy storage system.
Historical hourly wind speed, solar irradiance, and load data are
used to stochastically model the wind generation, photovoltaic
generation, and load. Using fuzzy C-Means (FCM) clustering,
these data are grouped into 10 clusters of days with similar data
points to account for seasonal variations. In order to minimize
cost and increase efficiency, we use a GA-based optimization
approach together with a two-point estimate method. Minimizing
the cost function guarantees minimum PV and

Description: Texture-Aware Fast Global Level Set Evolution-Due to its intrinsic advantages such as the ability to automatically handle complex shapes and topological changes, the level set method has been widely used in image segmentation. Nevertheless, in addition to be computational expensive, it has the limitation to very often lead to a local minimum because of the energy functional to be minimized is non-convex. In this work, we use the geometric active contours and the image thresholding frameworks to design a novel method for global image segmentation. The local lattice Boltzmann method is used to solve the level set equation. The proposed algorithm is therefore effective and highly parallelizable. Experimental results on satellite, natural and medical images demonstrate the effectiveness and the efficiency of the proposed method when implemented using an NVIDIA graphics processing units
The present Matlab code is the implementation of our work.
For using:
1- Open the main code (TAFGLSE.m),

Description: crazyflie python源码
Theseankelly, from the community, has started a Windows client for Crazyflie 2.0. It connects Crazyflie using bluetooth low energy and works both on phone and on PC running windows. Last week, he transferred the source code repos in the Bitcraze github so that it can have more visibility. We plan to eventually released it in the Windows store, but first it needs to have a little bit more features :-). To this end we have created a milestone on GitHub and have filled a couple of tasks. The plan is to get to a minimum set of functionalities. That for, we will focus on phone support first but if you are interested in PC support do not hesitate to say so and push tickets for it (gamepad support and configuration is the first thing I can think about for desktop support).
Last week Fred released a new version of the Android client. The outstanding new feature is a support of the LED and Buzzer decks when using Crazyradio! It means that you can now change the light effects and play sounds on the Crazyflie from the phone. This is even better because it means that the Android client code is now able to access the param subsystem and soon the log subsystem: this will allow for much more interactions in the future (like access to advanced Crazyflie settings and supporting more decks). The support of decks using BLE and more are on going so stay tuned and if you have any functionality request please head to the GitHub ticket tracker.
