OPTIMIZATION OF SIMP (SOLIDITY, INTEGRITY, MENTALITY, PROFESSIONALITY) ELECTION SUPERVISORS TO ACHIEVE DEMOCRATIC, HONEST AND FAIR ELECTIONS

A democratic country is a country whose government is run based on the principle of popular sovereignty. Popular sovereignty means that the people have the ultimate power to determine state policies and regulations. The people can use this power in various ways, such as elections, referendums, and petitions. The purpose of this writing is to maximize the performance of general election supervisors to realize democratic, honest and fair general elections. The research method uses descriptive qualitative analysis using data taken from literature sources and then analyzed. The results of the study that as election organizers must have an attitude of solidarity, integrity, mentality and professionalism. The responsibility of the election supervisor is the Election Supervisory Body (Bawaslu). Bawaslu as an institution responsible for implementing general elections is obliged to improve the loyalty, performance and behavior of election supervisors in order to achieve democratic, honest and fair general elections. Optimizing the behavior of election supervisors to improve integrity can be done with technical guidance, consolidation between election administrators and digitalization of supervisory applications

Risk Assessment of Rainwater Overflow from Lake Warouwaye in the Case of a Ten-Year Rainfall in Yeumbeul North, Senegal

This study is a part of a global approach in which, the main purpose is to understand the reasons behind the upsurge of flood events in the peri-urban area of the city of Dakar. Hydrological and hydraulics simulations were carried out to assess the risks of overflowing of the Lake Warouwaye after a so-called exceptional rain. Data were collected through field surveys, as well as site observations of dwellings before and after rain episodes. The simulations were performed using EPA’s Storm Water Management Model (SWMM) software with input data obtained from sub-software and supervisory applications such as Google Earth, Excel, and Global Mapper. The simulation results show factors of natural and anthropogenic origin may contribute to dysfunction hydrological elements such as the watershed capacity to drain and store water. In light of the results of this study, institutional governance efforts are to be made and to be sustained in order to reverse the tendency to occupy rainwater natural flow channels. It will also be necessary to involve the first actors who are the potential victims of flooding caused by the recurrent overflow of reservoirs.

On the current state of flotation modelling for process control

Despite significant effort in modelling and simulating flotation circuits, comprehensive model based control and optimisation implementations on industrial circuits remain scarce. In this paper, the factors preventing more widespread implementation of model-based control and optimisation applications are investigated by focussing on three aspects. Firstly, the critical variables required in a simplified flotation model are identified. Models that are currently used in control, optimisation and supervisory applications are thereafter analysed to determine to what extent the required variables are modelled. Finally, online instrumentation available to support these models are investigated, also including instrumentation that is still under development and not commonly available in commercial applications. Although models used in control applications tend to focus on subsections of the flotation process, there seem to be a good agreement between the required and modelled variables. Model fitting however often relies on extensive sampling campaigns that will need to be repeated regularly to maintain model accuracy. A number of online measurements of sufficient accuracy are still not available to support these models, compromising the long term reliable use of models in online applications. The fact that flotation processes are in many instances not extensively instrumented, constrains online maintenance and adaption of model based solutions further.

Dynamic Secrets and Secret Keys Based Scheme for Securing Last Mile Smart Grid Wireless Communication

An integrated and optimized smart grid cannot be achieved without a secure communication network. Due to the large-scale nature of the power system, the variety of technologies used, and limitations of communication bandwidth, supervisory applications for smart grid still use weak security in many deployments. Adversaries can potentially modify measurement values or inject bad commands over the network. In this paper, we propose a novel scheme based on dynamic secrets and encryption with secret keys. The scheme generates a series of dynamic secrets over the communication network, which are used to generate secret keys for data encryption. The generation of dynamic secret is frequent and no adversary can compromise the network for a longer period, even if he/she knows a secret key. The scheme is secure against eavesdropping, malicious communication injection, man-in-the-middle attacks, replay attacks, impersonation attacks, and chosen-plaintext attacks. The security analysis and performance evaluation show that our scheme is feasible to be used in the communications between supervisory and control nodes of various smart grid applications.

Computer vision assisted virtual reality calibration

A computer vision assisted semi-automatic virtual reality (VR) calibration technology has been developed that can accurately match a virtual environment of graphically simulated 3D models to the video images of the real task environment. We have developed a new 20-variable weighted least-squares algorithm that updates both camera and object models simultaneously for given two camera views of two mating objects. This simultaneous update enables accurate model matching even with rough, approximate initial camera calibrations. The developed semi-automatic VR calibration supports automated intermediate updates, eliminating nearly all operator interaction except for initial coarse matching. In our quasi-static supervisory telerobotic applications, intermediate VR calibrations are performed intermittently at a few robot stopping poses only, as a cost-effective and safer approach compared to real-time visual servoing. Extensive experimental results comparing alignment errors under various viewing conditions are presented.
