The United Nations Declaration on the Rights of Indigenous Peoples (UNDRIP) stands as the most prominent international human rights instrument that defines and protects the rights of indigenous peoples globally. While it represents a landmark achievement, it significantly lacks comprehensive provisions addressing the rights of indigenous women, particularly environmental rights. This study undersc
For those who experience development-induced displacement and involuntary resettlement, they have to confront a range of adverse consequences, including the impoverishment risks, lifestyle and livelihood changes, and the precarity brought by asymmetrical power relations. Based on a case study of the Three Gorges Project (TGP), this research investigates the role of state law in shaping the identit
A method is presented for assessing disturbances in SISO loops.The method indicates if the SISO loop under consideration will benefit from an addition of feed forward control from a measured disturbance. The method uses minimal process knowledge and is based on measurement from normal operation.
With the rise of Internet of Things (IoT) accessories such as network attached cameras, light bulbs and thermostats are all constantly connected to the Internet and security concerns must be taken seriously. If a bug exists in an application it could be hacked by a malicious adversary that then could harm the underlying system, leak information or attack other devices or networks. Applications sho
In this study, design of low-order feedforward controllers from both reference signal and measurable disturbance for proportional–integral–derivative (PID) controllers is considered. The feedforward controllers from reference are equivalent to the use of a PID controller with set-point weighting. The design problem is formulated as a convex optimisation problem and then solved for a batch of proce
This paper presents new tuning rules for PIcontrol of processes with essentially monotone step response that aretypically encountered in process control. The rules are based oncharacterization of process dynamics by three parameters that can beobtained from a step response experiment. The rules are obtained bymaximizing integral gain subject to a constraint on themaximum sensitivity. They are almo
Tuning an ideal PID and then using its parameters in a real one, can yield undesired results. Nonetheless, many rules conceived for the ideal PID are successfully used in practice, owing to their greater flexibility. A systematic method would thus be useful to extend ideal PID tuning rules to the real PID, so as to preserve said flexibility while synthesising a realistic controller. This manuscrip
Objectives: The role of persistent chlamydial infection of the Fallopian tubes in ectopic pregnancy is still unresolved. Therefore, we examined tissue of the Fallopian tubes from patients with ectopic pregnancy for the presence of Chlamydia trachomatis. In addition, other markers of C. trachomatis infection implicated in the pathogenesis of tubal damage were studied including antibodies to heat sh
Software development for embedded systems has a lot of dependencies on the hardware of the system. To possibly reduce the lead time and ease the development process, an emulated model is investigated. This model is examined in terms of how it fits in the platform transition, daily development and testing processes at Axis. The results indicate that an emulated model is a powerful tool for a softwa
In this paper, a performance benchmark for the assessment of two feedforward control architectures for the load disturbance compensation problem is proposed. In particular, two indices are devised so that the advantage of using a feedforward compensator with respect to the use of a feedback controller only is quantified. Furthermore, these metrics will help to make quantitative comparisons among d
This paper is intended to answer the question: “When is a simple dead-time compensator expected to perform better than a PID?”. The performance criterion used is the integrated absolute error (IAE). It is compared for PI and PID controllers and a simple dead-time compensator (DTC) when a step load disturbance is applied at the plant input. Both stable and integrating processes are considered.
