This paper proposes a systematic method to identify the joint zero offset of industrial robot. Small offset always exist in robot joint, which affect the precision in kinematic equations leading to calculate wrong joint angle values. To solve these problems, the proposed method employs a portable dual Position Sensitive Detector (PSD) device and a focusable laser point (FLP). The portable dual ...

IP can help to address social challenges, including health care, poverty and food security, and environmental sustainability. Innovation is a critical part of the solution when tackling important societal challenges, and IP rights provide businesses with incentives to invest in relevant inventions so as to produce needed innovations. Creating this knowledge and facilitating access and transfer ...

More and more organizations cooperate in networks to perform increasingly complex tasks. Rather than managing their resources in isolation, organizations construct inter-organizational networks in which flows of information support joint value-creating processes. Organizations participating in such networks need to understand how closer cooperation with selected members of that network can be f...

In the human brain, forgetting is a very effective way of focusing on the important things, while unstressing irrelevant details. In the ForgetIT project, we use forgetting and other processes in the human brain such as the context-driven reconstruction of memories as an inspiration for creating intelligent methods for joint information and preservation management. In this paper, we present sel...

Synthetic DNA oligonucleotides can direct the exchange of single nucleotides within coding regions of mammalian genes by hybridizing to their complementary sequence in the chromosome and creating a recombination joint structure with a single mismatched base pair. Inherent DNA repair processes recognize the mismatch and resolve it using the DNA sequence of the oligonucleotide vector as the templ...

Two trapped ions that are kilometers apart can be entangled by the joint detection of two photons, each coming from one of the ions, in a basis of entangled states. Such a detection is possible with linear optical elements. The use of two-photon interference allows entanglement distribution free of interferometric sensitivity to the path length of the photons. The present method of creating ent...

Collaborative Virtual Environments provide the capability of remote users working together in a virtual reality simulation in order to accomplish a joint task. An application creating such an environment would make heavy use of 3-dimensional object descriptions and hence would require their efficient storage, transport and access. In this paper we will discuss the suitability and advantages of ...

aim: abnormal joint mobility is an important factor in movement dysfunction and physical disability. a general lack of descriptive details exists for measurements of hip rotation range of motion (rom). this study was designed to establish the influence of hip position on active and passive range of motion of the hip in external and internal rotation(ext & int rot). material & methods: ...

in this research, the influence of bolt preload on the fatigue strength of 2024-t3 aluminium alloy double lap bolted joints has been studied experimentally and numerically. to do so, three sets of the specimens were prepared and each of them subjected to tightening torque of 1,2.5 and 5 n-m and then fatigue tests were conducted under various cyclic axial load levels. in the numerical method, th...

abstract   background: sacroiliac joint (sij) dysfunction is a widely known but poorly defined   cause of low back pain. to our knowledge, few published studies have been   conducted to evaluate systematically the prevalence and significance of concomitant   sacroiliac joint dysfunction in patients with herniated lumbar discs. as concomitant   sij dysfunction in low back pain patients is likely...
