the problem of navigation among movable obstacles (namo) is to find a collision free path for a robot while the robot is able to manipulate and transfer some objects (if possible or needed) to clear its path toward the goal. namo is a np-complete problem and is in a class of motion planning problems that have dynamic environments. in this domain, an optimal plan for the robot can be defined wit...

Problem statement: In multihomed host, if data transfer starts using CMT, unaware of paths status causes delay in data transfer or packet loss due to path failure. Transmission Path (one or more paths) failures result in out-of-order data delivery causing receiver buffer blocking and preventing sender from transmitting further data. Approach: Multipath State Aware Concurrent Multipath Transfer ...

A sensor network is made up of a large number of sensors with limited energy. Sensors collect environmental data then send them to the sink. Energy efficiency and thereby increasing the lifetime of sensor networks is important. Direct transfer of the data from each node to the central station will increase energy consumption. Previous research has shown that the organization of nodes in cluster...

End-to-end data transfer has long been a fundamental service of Internet. With the trend of multi-interface communication terminals and redundant paths between them both in cellular networks and in the Internet, efficient protocols of multipath transfer are needed to gain the benefits of multi-interfaces. In this paper, we propose SAR-RMTP, a Self-adapted Rescheduling Reliable Multipath Transfe...

Generally speaking, a vibration system consists of three parts: vibration resource, vibration transfer path, and vibration receiver. Based on the dynamic sensitivity technique, this paper proposes a method for evaluating the contribution of each vibration transfer path to the dynamic response of the vibration receiver. Nonlinear stiffness is an important factor in causing the nonlinearity of vi...

This paper presents data fusion algorithm of fault diagnosis considering sensor measurement uncertainty. Random-fuzzy variables (RFV) are used to model testing patterns (TPs) and fault template patterns (FTPs) respectively according to on-line sensor monitoring data and typical historical sensor data reflecting every fault mode. A similarity measure is given to calculate matching degree between...

In this paper we present an analysis of over 236,000 file transfers between 10 widely distributed Internet hosts. The goal of this work is to broaden the understanding of how network path and congestion properties contribute to delays in TCP file transfers. The first part of our analysis investigates how end-to-end path properties (eg. physical distance, router hops, autonomous system hops, or ...

Many problems concerning lattice paths, especially on the square lattice have been accurately solved. For a single path, many methods exist that allow exact calculation regardless of whether the path inhabits a strip, a semi-infinite space or infinite space, or perhaps interacts with the walls themselves. It has been shown that a transfer matrix method using the Bethe Ansatz allows for the calc...

Binaural Transfer Path Analysis (BTPA) was originally developed for assessing the binaural contributions of individual vehicle noise paths. It is a powerful modeling tool enabling engineers to explore noise transfer mechanisms by distinguishing between excitation source strengths and the transfer behavior of individual elements. The method is well-known for powertrain noise analysis, including ...
