Pembuatan Aplikasi Simulasi Ujian Praktik Pengambilan Surat Izin Mengemudi Kendaraan Roda Empat

The development of video games today have been growing rapidly. The latest technology, allows users to feel like in the virtual world of a video game. Simulation Game is one genre that can teach something to the user. Simulation Games like driving simulator can be used as a training tool before encountering a real condition with real vehicles.This thesis will generate a 3-dimensional application that can simulate practice exams for four-wheeled vehicles. The development of the application is using Unity Engine program with C# programming language. Logitech G27 Steering Wheel is used as the controller.The test results showed that the steering wheel device can generate output in accordance with steering control on the car. In this thesis, the test results indicate that the materials of practice test are made in 3-dimensional view is look alike reality with the practice of the real exam. This application also can be done by using the device steering wheel to steer the car in a virtual world

Analisis Sistem Pemasaran Stroberi pada Koptan Bali Buyan Berry di Desa Pancasari Kabupaten Buleleng

Analysis of Marketing System Strawberry on Koptan Bali Buyan Berry in the Village of Pancasari District Buleleng The study aims to determine of the function, structure, conduct and the performance of the market. Data used in this study is qualitative data and quantitative data, the data obtained and analyzed. The results showed on the functioning of the market there are three functions, namely market exchange, physical and facilities. Total of marketing agencies that are in the market structure as much as 1 merchant wholesalers, traders inter-city, inter-island trader and 4 retailers. Pricing in the study by bargaining and how to pay the monthly farmers with cash, the inter-city merchant cash once a month, on the inter-island trader bimonthly cash and at retailers with cash paid on the spot. The performance of the market and the marketing margin is calculated with the farmer\u27s share. At first marketing channel marketing margin is IDR 12,000 to the farmer\u27s share of 53.84%, the second marketing channel marketing margin is IDR 14,000 to the farmer\u27s share of 50% and the third marketing channel marketing margin of IDR 17,250 to the farmer\u27s share of 44.48%. Farmers should sell strawberries not only to the marketing agencies that already have the attachment of cooperation in order to obtain a higher sales price

RoSSO: A High-Performance Python Package for Robotic Surveillance Strategy Optimization Using JAX

To enable the computation of effective randomized patrol routes for single- or multi-robot teams, we present RoSSO, a Python package designed for solving Markov chain optimization problems. We exploit machine-learning techniques such as reverse-mode automatic differentiation and constraint parametrization to achieve superior efficiency compared to general-purpose nonlinear programming solvers. Additionally, we supplement a game-theoretic stochastic surveillance formulation in the literature with a novel greedy algorithm and multi-robot extension. We close with numerical results for a police district in downtown San Francisco that demonstrate RoSSO's capabilities on our new formulations and the prior work.Comment: 7 pages, 4 figures, 3 tables, submitted to the 2024 IEEE International Conference on Robotics and Automation.

A Stochastic Surveillance Stackelberg Game: Co-Optimizing Defense Placement and Patrol Strategy

Stochastic patrol routing is known to be advantageous in adversarial settings; however, the optimal choice of stochastic routing strategy is dependent on a model of the adversary. We adopt a worst-case omniscient adversary model from the literature and extend the formulation to accommodate heterogeneous defenses at the various nodes of the graph. Introducing this heterogeneity leads to interesting new patrol strategies. We identify efficient methods for computing these strategies in certain classes of graphs. We assess the effectiveness of these strategies via comparison to an upper bound on the value of the game. Finally, we leverage the heterogeneous defense formulation to develop novel defense placement algorithms that complement the patrol strategies.Comment: 9 pages, 1 figure, jointly submitted to the IEEE Control Systems Letters and the 2024 American Control Conference.

Haptic guidance improves the visuo-manual tracking of trajectories

BACKGROUND: Learning to perform new movements is usually achieved by following visual demonstrations. Haptic guidance by a force feedback device is a recent and original technology which provides additional proprioceptive cues during visuo-motor learning tasks. The effects of two types of haptic guidances-control in position (HGP) or in force (HGF)-on visuo-manual tracking ("following") of trajectories are still under debate. METHODOLOGY/PRINCIPALS FINDINGS: Three training techniques of haptic guidance (HGP, HGF or control condition, NHG, without haptic guidance) were evaluated in two experiments. Movements produced by adults were assessed in terms of shapes (dynamic time warping) and kinematics criteria (number of velocity peaks and mean velocity) before and after the training sessions. CONCLUSION/SIGNIFICANCE: These results show that the addition of haptic information, probably encoded in force coordinates, play a crucial role on the visuo-manual tracking of new trajectories

Cell morphology drives spatial patterning in microbial communities

The clearest phenotypic characteristic of microbial cells is their shape, but we do not understand how cell shape affects the dense communities, known as biofilms, where many microbes live. Here, we use individual-based modeling to systematically vary cell shape and study its impact in simulated communities. We compete cells with different cell morphologies under a range of conditions and ask how shape affects the patterning and evolutionary fitness of cells within a community. Our models predict that cell shape will strongly influence the fate of a cell lineage: we describe a mechanism through which coccal (round) cells rise to the upper surface of a community, leading to a strong spatial structuring that can be critical for fitness. We test our predictions experimentally using strains of Escherichia coli that grow at a similar rate but differ in cell shape due to single amino acid changes in the actin homolog MreB. As predicted by our model, cell types strongly sort by shape, with round cells at the top of the colony and rod cells dominating the basal surface and edges. Our work suggests that cell morphology has a strong impact within microbial communities and may offer new ways to engineer the structure of synthetic communities
