Research on the Influence of Early Experience on the Growth Rate of Science and Engineering Graduate Supervisors

This research is based on three northeastern double first-class polytechnic universities.A total of 1628 science and engineering graduate supervisors?resumes were referred to from an official website by the random sampling method,of which only 500 supervisors were included in consideration of complete information,key events,and time in terms of the educational background(undergraduate school,graduate school,doctoral school,number of masters,number for Dr.),early work background(number of postdocs,number of overseas visits,numbers of research work),and the growth rate(period from graduation to associate professor title).The higher education background and early work background were defined as early experience,and the database of these 500 science and engineering graduate supervisors with complete resume information from three double first-class universities in northeastern China was established.In this study,the growth rate of the growth period was divided into two at the critical period:the growth rate of the graduate supervisor to associate professors.Through stepwise multiple regression analysis,it was found that higher education background(undergraduate schools,graduate schools,doctoral schools,as well as the number of master's and doctorate degrees)as well as early work background(number of postdoctoral work,research work,and overseas visits)have a significant impact on the growth rate of graduate supervisors to associate professors.

Optimal deadlock avoidance Petri net supervisors for automated manufacturing systems

Deadlock avoidance problems are investigated for automated manufacturing systems with flexible routings. Based on the Petri net models of the systems, this paper proposes, for the first time, the concept of perfect maximal resourcetransition circuits and their saturated states. The concept facilitates the development of system liveness characterization and deadlock avoidance Petri net supervisors. Deadlock is characterized as some perfect maximal resource-transition circuits reaching their saturated states. For a large class of manufacturing systems, which do not contain center resources, the optimal deadlock avoidance Petri net supervisors are presented. For a general manufacturing system, a method is proposed for reducing the system Petri net model so that the reduced model does not contain center resources and, hence, has optimal deadlock avoidance Petri net supervisor. The controlled reduced Petri net model can then be used as the liveness supervisor of the system.

Non-Deterministic Liveness-Enforcing Supervisor Tolerant to Sensor-Reading Modification Attacks

In this paper, we study the supervisory control problem of discrete event systems assuming that cyber-attacks might occur. In particular, we focus on the problem of liveness enforcement and consider a sensor-reading modification attack(SM-attack) that may disguise the occurrence of an event as that of another event by intruding sensor communication channels. To solve the problem, we introduce non-deterministic supervisors in the paper, which associate to every observed sequence a set of possible control actions offline and choose a control action from the set randomly online to control the system. Specifically, given a bounded Petri net(PN) as the reference formalism and an SMattack, an algorithm that synthesizes a liveness-enforcing nondeterministic supervisor tolerant to the SM-attack is proposed for the first time.

Smaller & Smarter: Score-Driven Network Chaining of Smaller Language Models

With the continuous evolution and expanding applications of Large Language Models (LLMs), there has been a noticeable surge in the size of the emerging models. It is not solely the growth in model size, primarily measured by the number of parameters, but also the subsequent escalation in computational demands, hardware and software prerequisites for training, all culminating in a substantial financial investment as well. In this paper, we present novel techniques like supervision, parallelization, and scoring functions to get better results out of chains of smaller language models, rather than relying solely on scaling up model size. Firstly, we propose an approach to quantify the performance of a Smaller Language Models (SLM) by introducing a corresponding supervisor model that incrementally corrects the encountered errors. Secondly, we propose an approach to utilize two smaller language models (in a network) performing the same task and retrieving the best relevant output from the two, ensuring peak performance for a specific task. Experimental evaluations establish the quantitative accuracy improvements on financial reasoning and arithmetic calculation tasks from utilizing techniques like supervisor models (in a network of model scenario), threshold scoring and parallel processing over a baseline study.

The Design of Supervisory Institutions in the Ming Dynasty and Its Enlightenment to Modern Society

The supervisory system and the examination system are two indigenous political systems of China,and the former has a longer history than the latter when it comes to the origin.Having inherited the essence of the supervisory system since the Qin Dynasty,the supervisory rules in the Ming Dynasty opened a new chapter of legal thoughts of monitoring.This paper started with the design of the supervisory institutions in the Ming Dynasty recorded in the historical materials such as the Memoir of Ming Dynasty and The Interpretive Supplements to"The Great Learning",to get a glimpse of the main content of the legal thoughts of supervisory at that time,and tried to"take history as a mirror"to provide insights and lessons of the legal thoughts of supervisory in the Ming Dynasty for the later generations.

Deadlock-free Supervisor Design for Robotic Manufacturing Cells With Uncontrollable and Unobservable Events

In this paper,a deadlock prevention policy for robotic manufacturing cells with uncontrollable and unobservable events is proposed based on a Petri net formalism.First,a Petri net for the deadlock control of such systems is defined.Its admissible markings and first-met inadmissible markings(FIMs)are introduced.Next,place invariants are designed via an integer linear program(ILP)to survive all admissible markings and prohibit all FIMs,keeping the underlying system from reaching deadlocks,livelocks,bad markings,and the markings that may evolve into them by firing uncontrollable transitions.ILP also ensures that the obtained deadlock-free supervisor does not observe any unobservable transition.In addition,the supervisor is guaranteed to be admissible and structurally minimal in terms of both control places and added arcs.The condition under which the supervisor is maximally permissive in behavior is given.Finally,experimental results with the proposed method and existing ones are given to show its effectiveness.

英语世界中的“导师”概念及其职责辨析——兼论中西方“导师”用语及其职责的差别与当代启示

借由日语进入汉语的“导师”一词在英语世界中有三个常被混用的词汇——mentor、advisor及supervisor。经词源考辨,这三个词的内涵分别侧重引导、建议和监管,其外延范围广泛且不局限于专指研究生导师。当“导师”作为研究生导师使用时,其职责主要体现在为研究生提供学术、情感和职业支持。mentor大致属于“高学术、高情感、高职业”支持型,advisor大致属于“中学术、高情感、中职业”支持型,supervisor大致属于“高学术、低情感、低职业”支持型。对比中国与英美国家研究生导师的概念及职责发现,双方“导师”的职责均涉及上述三个职责维度。但是,英美国家的研究生导师因其用词的变化常蕴含职责侧重上的微妙差别,而中国的研究生导师则对研究生负有全面的指导职责。这一研究对于研究者在研究生教育领域开展精准的学术对话,进而深刻把握英美国家的导师制度及其与中国的差别具有重要的意义。

Assessment of Clinical Learning Environment, Supervision (CLES) among Nursing Students, Hyderabad, Sindh, Pakistan

Background: In nursing education for better teaching and essential professional skills, the clinical practice plays a substantial role. Practice at clinical settings permits students to convert theoretic knowledge into the knowledge of the skills mandatory for the care of the patient. Clinical learning environment (CLE) is an important part in education of nursing and has a sizable influence on the students’ learning. Objective: The purpose of this study is to examine perception and satisfaction of nursing students with their CLEs in Hyderabad, Pakistan. Methods: This cross-sectional study was conducted at three nursing institutes of Hyderabad from December 2018 to January 2019 among 342 nursing students. Clinical Learning Environment, Supervision and Nurse Teacher (CLES + T) assessment tool was used as the instrument to identify the students’ perception about the learning environment in clinical setting. Results: The mean age of the participants was 25.6 ± 4.93 with majority of them male (70.7%). Three domains, pedagogical atmosphere, supervisory relationship and nurse teacher role in clinical practice showed good reliability of more than 70%. Highest domains vise mean score was obtained for nursing premises on the ward (3.315) whereas lowest for nurse teacher role in clinical practice (NT) (3.062). Analysis of variance revealed that three domains supervisory relationship, leadership style of the ward manager and premises of nursing showed significant mean score difference among supervisor title. Conclusion: It was found that students valued positive supervision, ward manager leadership style premises of nursing on the ward as positive CLE. Learning environment varies between gender, clinical settings and supervision. Medicine ward appeared to deliver the finest learning situations for the nursing program.

Reinforcement Learning Behavioral Control for Nonlinear Autonomous System

Behavior-based autonomous systems rely on human intelligence to resolve multi-mission conflicts by designing mission priority rules and nonlinear controllers.In this work,a novel twolayer reinforcement learning behavioral control(RLBC)method is proposed to reduce such dependence by trial-and-error learning.Specifically,in the upper layer,a reinforcement learning mission supervisor(RLMS)is designed to learn the optimal mission priority.Compared with existing mission supervisors,the RLMS improves the dynamic performance of mission priority adjustment by maximizing cumulative rewards and reducing hardware storage demand when using neural networks.In the lower layer,a reinforcement learning controller(RLC)is designed to learn the optimal control policy.Compared with existing behavioral controllers,the RLC reduces the control cost of mission priority adjustment by balancing control performance and consumption.All error signals are proved to be semi-globally uniformly ultimately bounded(SGUUB).Simulation results show that the number of mission priority adjustment and the control cost are significantly reduced compared to some existing mission supervisors and behavioral controllers,respectively.

Cognitive Supervisor for an Autonomous Swarm of Robots

As a sequel to our recent work [1], in which a control framework was developed for large-scale joint swarms of unmanned ground (UGV) and aerial (UAV) vehicles, the present paper proposes cognitive and meta-cognitive supervisor models for this kind of distributed robotic system. The cognitive supervisor model is a formalization of the recently Nobel-awarded research in brain science on mammalian and human path integration and navigation, performed by the hippocampus. This is formalized here as an adaptive Hamiltonian path integral, and efficiently simulated for implementation on robotic vehicles as a pair of coupled nonlinear Schr?dinger equations. The meta-cognitive supervisor model is a modal logic of actions and plans that hinges on a weak causality relation that specifies when atoms may change their values without specifying that they must change. This relatively simple logic is decidable yet sufficiently expressive to support the level of inference needed in our application. The atoms and action primitives of the logic framework also provide a straight-forward way of connecting the meta-cognitive supervisor with the cognitive supervisor, with other modules, and to the meta-cognitive supervisors of other robotic platforms in the swarm.
