Fully Connected Drill Boring Machine Excavation Face of Hydraulic System

Coal Technology (2011)

JI Jun-cheng

The fully mechanized coal face in the front must have a drill boring machine.First hit the eye backward road.Kick down the eye,drilling,pumping station,console,switches,cables,etc.,must withdraw behind the boring machine,heavy workload and high labor intensity,therefore,the need to study the tunneling machine to provide hydraulic power for the drilling work.In addition,procurement of drilling rigs ordered the body only when the other is not set,can reduce procurement costs.

A Dynamic Negative Log-Likelihood Optimization Method for Device Selection in Federated Learning with Over-The-Air Computation

2021 7th International Conference on Computer and Communications (ICCC) (2023)

JI Jun-cheng Chan‐Tong Lam Ke Wang Benjamin K. Ng

This paper addresses an optimization problem of device selections and aggregation errors in over-the-air computation with federated learning (AirCompFL) systems. To achieve this, we first propose an AirCompFL system model and then formulate the device selections problem as a multi-objective mixed integer programming problem. We then propose a dynamic negative log-likelihood weighted optimization decision (DNLWOD) approach to solve the above problem. The method selects a device based on multiple criteria for enhancing the overall performance, which optimizes the weight of each criterion to balance and minimize aggregation errors automatically and simultaneously. Experimental results show that the DNLWOD method can effectively reduce aggregation errors to enhance the performance of the AirCompFL system, outperforming the existing algorithms in terms of the overall performance, average performance and aggregated error. This work shows that in a wireless edge networking environment with the AirCompFL system, the proposed scheme can provide an effective strategy for selecting devices and optimizing aggregation to increase the communication efficiency and mitigate the aggregation errors.

Clinical observation of surgical treatment of gastric ulcer

Central Plains Medical Journal (2019)

Yuxing Li JI Jun-cheng

Objective To explore the clinical effect of surgical treatment of gastric ulcer. Methods A total of 76 patients with gastric ulcer treaded from December 2016 to December 2018 in the First People’s Hospital of Yangquan were divided into two groups. The 38 cases in the control group were treated with routine conservative treatment, and 38 cases in the observation group were treated by surgery. Results In the observation group, the total effective rate (97.37% ) was higher and complication rate (18.42%)were lower than those in the control group; the recurrence rate of the observation group was lower than those of the control group in 3 months (0) and 6 months (5.26%) after operation. Conclusions The overall curative effect of surgical treatment for gastric ulcer patients is more remarkable, the complication rate and recurrence rate are lower, and the surgical treatment has higher application value.
