Welcome to the Listening Time podcast. Hey everybody this is Coner and you are listening to episode 123 of the Listening Time podcast I hope you are all doing great at the time of recording this it’s the very end of summer here in the Northen of ?hemisphere and so autumn is just around the corner in English when we say that something is just around the corner we are saying that it’s just about to appear or it’s about to happen it’s gonna happen very soon.

So fall is just around the corner and a lot of people are really happy about this because a lot of people here like this season they like autumn they like to see the colors'->\ changing they like this season or food->seasonal food there are a lot of different kind->types of food that people start to eat during the->\ autumn that they don’t eat in->during the spring or summer and so a lot of people like this season.

One fun thing about this season is there’re a lot of activities for childern for example pangkong->pumpkin patches these are->\ places where they see->sell pumpkins but they also have a lot of activities for kids and me and my family we are planing on going to a couple of pumpkin patches this season and I think i will do an episode on pumpkin pathches so you’ll get to hear about that hopefully.

And I was thinking about this episode->topic of fun activities for children because I was thingking of pumpkin patches and a->about different things like that and i decided that i wanted to do an episode about some of my favorite activities that I did when I was a kid. So my childhood activities specific things that I did outdoors. Things I did outside I thought I->it would be fun to look back and remember my childhood and some of my favorite things that i did outside so i hope that this is->will be an interesting episode for you today.

And before we start i want to remind you that my new podcast is avaliable now Us conversations where I talk to different English teachers from around the US and we talk about many things and have natural conversations with->at normal speed and you have a->the transcript availbale with the definations of keywords and phrases we use so make sure to sign up for that if you are interested the link is in the episode description below this episode that is patreon.com/usconversations.

And if you want my specialized training to help you undersatand native speakers when they speak fast then make sure to join my membership the link is also in the description of->below this episode so click on that and join if you are interested in getting my specialized training.

And of course if you are a Spanish or Portuguess speaker you can also check out my e-book if you want to start reading fictions->\ in English those links are down below as well and if you like this episode please share it with anyone else you know who is learning English and please give it a five-star rating and write a review. Alright let’s get started.

Are you ears ready? you know what time it is. It’s listening time.

Alright let’s talk about some of my favorite childhood activities that i did. some of my favorite things i did outdoor->outdoors because i did somethings in doors->indoors as well i have->had some fun activities that i did inside. but i want to focus on the outdoors activies today. so the first one that i want to talk about is buiding a tree house so you’ve probably seen this in movies or TV shows before where the kids build an some types->some type of house in their back yard->backyard maybe in a big tree and this is something that is pretty class->classic trandition here in the US.

内容概要:本文介绍了一个基于MATLAB实现的无人机三维路径规划项目,采用蚁群算法(ACO)与多层感知机(MLP)相结合的混合模型(ACO-MLP)。该模型通过三维环境离散化建模,利用ACO进行全局路径搜索,并引入MLP对环境特征进行自适应学习与启发因子优化,实现路径的动态调整与多目标优化。项目解决了高维空间建模、动态障碍规避、局部最优陷阱、算法实时性及多目标权衡等关键技术难题,结合并行计算与参数自适应机制,提升了路径规划的智能性、安全性和工程适用性。文中提供了详细的模型架构、核心算法流程及MATLAB代码示例,涵盖空间建模、信息素更新、MLP训练与融合优化等关键步骤。; 适合人群:具备一定MATLAB编程基础,熟悉智能优化算法与神经网络的高校学生、科研人员及从事无人机路径规划相关工作的工程师;适合从事智能无人系统、自动驾驶、机器人导航等领域的研究人员; 使用场景及目标:①应用于复杂三维环境下的无人机路径规划,如城市物流、灾害救援、军事侦察等场景;②实现飞行安全、能耗优化、路径平滑与实时避障等多目标协同优化;③为智能无人系统的自主决策与环境适应能力提供算法支持; 阅建议:此资源结合理论模型与MATLAB实践,建议者在理解ACO与MLP基本原理的基础上,结合代码示例进行仿真调试,重点关注ACO-MLP融合机制、多目标优化函数设计及参数自适应策略的实现,以深入掌握混合智能算法在工程中的应用方法。
