In this paper, the new concept of the dynamic singular configuration of flexible manipulators is proposed. When we control flexible manipulators using the inverse dynamics method, we need to consider this dynamic singular configuration of flexible manipulators. Without considering it, the control around the dynamic singular configuration may become unstable. As an example, we derive the dynamic...

Mature market economies steadily raise full-benefit retirement ages and add flexible (or variable) age: early/late is punished/rewarded to neutralize the budgetary impact of free choice within wide age limits. New EU member states also ages, but typically restrict downward flexibility, conditioning it on long enough length contribution (e.g., Czechia) sometimes even forsake deduction (Females40...

Wireless sensor network (WSN) have become one of the most promising technology in sensing application environment. WSNs environment are able to provide a flexible deployment and maintenance of sensor networks. The sensor nodes can be deployed in highly dynamic environments and hence enable sensor networks to be potentially used in a wide range environment including military applications, securi...

Dual-fuelling provides a suitable method for operating compression-ignition engines on alternative fuels. The CFD package Fluent is being used to model the direct-injection of two such fuels simultaneously into an engine. The CFD models have been initially calibrated using high-speed photographic visualisation of the jets. Different orientations and staging of the jets with respect to each othe...

The need for fast and precise robots in the industrial environment, capable of attending the productivity and quality demands and that allow a high volume of work, needs the usage of manipulators with flexible links. Besides this, aeronautic applications demand the usage of long and thin arms, which leads to remarkable structural changes. Therefore, the development of manipulators with structur...

Efforts towards commercializing higher-speed optical transmission have demonstrated the need for advanced modulation formats, several of which require similar transceiver hardware architecture. Adaptive transceivers can be built to have a number of possible operational configurations selected by software. Such software-defined transceiver configurations can create specific modulation formats to...

This article describes a prototype system for multimodal human-machine interaction in mobile environments that is being developed within the German national SmartKom research project. The system is novel in that it a) aims at combining the flexibility of state-of-the-art handheld digital devices with the computing power of standard PC machinery, and b) connects two substantially different mobil...

Main contribution of this work is improving transient stability by installing Flexible AC Transmission System (FACTS) in power systems. For do this, Unified Power Flow Controller (UPFC) has been selected. Also a novel structure has been suggested to improve classic Harmony Search algorithm and suggested improved Harmony Search (iHS) algorithm. This algorithm has been used to obtain UPFC paramet...

the aim of this research is to understand and assess the application of organizational learning capabilities in the status quo and review desirable situations in the context of the agricultural faculty environment. data were collected from 329 faculty members in 19 public agricultural faculties using a survey questionnaire. results indicate that organizational learning capabilities are below av...
