Desain dan Pengembangan Sistem Kecerdasan Robotika Muatan Roket dengan 5 Derajat Kebebasan dengan Kontrol Sistem Pendaratan Navigasi X-Y Kartesian

In this study a design and manufacture a rocket payload system that has the ability to fly autonomously intelligently is discussed. The rocket payload system was designed to be able to return to the landing position. This system consists of two sub systems, namely rocket payload and host computer (ground segment). A robotic-based rocket payload has a CPU-based system controller with a specific I/O for sensor-actuator is equipped with a set of telemetry systems. The I/O data can be sent to the host computer at the ground segment. Host computer with the ground segment is a useful tool to receive data from a rocket payload telemetry or navigation data which is then processed by a computer in the form of tables, graphs and map navigation. Direction control systems used for rocket payload system is fuzzy logic control with the input of compass and GPS data and the output scale propeller actuation to the system used by rocket payload. Testing of control systems was conducted in laboratory scale. Input is data of the desired setpoint with output in PWM DC Motor form to stabilize the rocket payload. The test results obtained for this direction control system to minimize the ∆error value of the set point desired direction so that the error is almost close to zer

A Development Environment for Visual Physics Analysis

The Visual Physics Analysis (VISPA) project integrates different aspects of physics analyses into a graphical development environment. It addresses the typical development cycle of (re-)designing, executing and verifying an analysis. The project provides an extendable plug-in mechanism and includes plug-ins for designing the analysis flow, for running the analysis on batch systems, and for browsing the data content. The corresponding plug-ins are based on an object-oriented toolkit for modular data analysis. We introduce the main concepts of the project, describe the technical realization and demonstrate the functionality in example applications

Towards Zero-Waste Furniture Design

In traditional design, shapes are first conceived, and then fabricated. While this decoupling simplifies the design process, it can result in inefficient material usage, especially where off-cut pieces are hard to reuse. The designer, in absence of explicit feedback on material usage remains helpless to effectively adapt the design -- even though design variabilities exist. In this paper, we investigate {\em waste minimizing furniture design} wherein based on the current design, the user is presented with design variations that result in more effective usage of materials. Technically, we dynamically analyze material space layout to determine {\em which} parts to change and {\em how}, while maintaining original design intent specified in the form of design constraints. We evaluate the approach on simple and complex furniture design scenarios, and demonstrate effective material usage that is difficult, if not impossible, to achieve without computational support

Threat Modelling for Active Directory

This paper analyses the security threats that can arise against an Active Directory server when it is included in a Web application. The approach is based on the STRIDE classification methodology. The paper also provides outline descriptions of countermeasures that can be deployed to protect against the different threats and vulnerabilities identified here

gCSP: A Graphical Tool for Designing CSP systems

For broad acceptance of an engineering paradigm, a graphical notation and a supporting design tool seem necessary. This paper discusses certain issues of developing a design environment for building systems based on CSP. Some of the issues discussed depend specifically on the underlying theory of CSP, while a number of them are common for any graphical notation and supporting tools, such as provisions for complexity management and design overview
